DETAILED DESCRIPTION OF THE EMBODIMENTS
The present disclosure is further described below in combination with the drawings.
A clamping force visualization device as shown in FIG. 4 and FIG. 5 includes a first clamping body 01 for clamping an object, the first clamping body 01 is telescopically assembled on a base 14, an elastic element 110 is provided between the first clamping body 01 and the base 14, a clamping force scale 11 is provided on the first clamping body 01, a reading indicator 15 is provided on the base 14, when the first clamping body 01 clamps the object, the elastic element 110 measures a clamping force, and the reading indicator 15 points to the clamping force scale 11 for reading, such that the magnitude of the clamping force can be intuitively seen and read, thereby achieving accurate clamping. During clamping, as the magnitude of the clamping force changes, the relative position between the reading indicator and the clamping force scale will change, therefore, during specific implementation, the positions of the reading indicator and the clamping force scale can be exchanged.
In order to achieve a compact structure and accurate measurement, the base 14 and the first clamping body 01 are sleeved together, as shown in FIG. 4 and FIG. 5, a window 16 is provided on the base 14 located at an outer side, the reading indicator 15 is provided at an edge of the window and the clamping force scale 11 visible through the window is provided on the first clamping body 01 located at an inner side. During specific implementation, the window may be provided on the first clamping body located on the outer side, the reading indicator is provided at the edge of the window, and the clamping force scale visible through the window is provided on the base located at an inner side. Further, the positions of the reading indicator and the clamping force scale may be exchanged regardless of which one of the base and the first clamping body is at the outer side.
In addition, as shown in FIG. 8, a front end edge of the base 14 located at the outer side is used as the reading indicator, and the clamping force scale is provided on the first clamping body located at the inner side. Obviously, the front end edge of the first clamping body located at the outer side may also be used as the reading indicator, and the clamping force scale is provided on the base located at the inner side.
In order to avoid the inaccuracy of measurement of the clamping force caused by the shaking of the clamping body, the base 14 is provided with an axial hole 17, the first clamping body 01 is provided with a telescopic section 12, and the axial hole 17 is sleeved on the telescopic section 12. Further, the telescopic section 12 is provided with an inner hole 13, one end of the elastic element 110 is supported at the bottom of the axial hole 17, and the other end of the elastic element 110 is supported at the bottom of the inner hole 13. The base is provided with a column 18, and the elastic element 110 is a helical compression spring sleeved on the column 18, so that the helical compression spring is supported by the column while ensuring a compact structure, thereby avoiding inaccuracy of measurement caused by the bending of the helical compression spring when the helical compression spring is pressed. In view of the supporting function of the column for the helical compression spring, the column may also be provided on the first clamping body.
In order to calibrate and adjust the initial pressure of the elastic element, an adjustment screw 111 is configured for the first clamping body, and the adjustment screw 111 passes through the first clamping body and is connected to the base 14 for maintaining the assembly relationship of the first clamping body, the base and the elastic element, and moreover, the initial pressure of the first clamping body on the elastic element may be adjusted by screwing the adjustment screw. Depending on use requirements, the initial pressure may be zero, or a certain pressure value. In view of this, the clamping force scale and the reading indicator may be marked (such as imprinting, laser marking and pad printing) at corresponding positions after calibration and adjustment. As shown in the figures, the first clamping body includes a pad 112 at an end port thereof, and the pad shields the adjustment screw. Likewise, a second clamping body includes a pad at an end portion thereof, and the pad may increase the contact with the clamped object while protecting the surface of the clamped object.
On the basis of the above clamping force visualization device, a clamp includes the clamping force visualization device and a second clamping body 02 cooperating with the first clamping body 01 to realize clamping, i.e. being able to be used for clamping an object, and the clamp may take various forms.

By gripping the first handle 38 and the second handle 41, clamping is achieved and is locked by the locking mechanism, and unlocking is achieved by operating the unlocking mechanism, so as to release the clamping.
Regardless which structure form the clamp is taken, both the base 14 and the first arm 03 may be made integrally together as shown in FIG. 8. Or, the base 14 is assembled on the first arm 03, such that the base, the first clamping body and the elastic elements form an integral structure as shown in FIG. 4 and FIG. 5, which is independent of other structures of the clamp, the independent structure has a relatively small volume, thereby facilitating circulation between stations when calibrating and adjusting the initial pressure of the elastic element.

Correspondingly, the end portion of the first arm which fits the clamping groove is provided with a head fitting with the clamping groove, and a snap-fitting with a certain pre-tightening force is realized by using the elasticity of a material (such as engineering plastics), so as to avoid separation. Such an assembly manner particularly facilities the assembly.

As shown in FIG. 11 and FIG. 12, the unlocking handle 33, the force-applying clamping piece 34, and the locking clamping piece 35 of the fourth type of fixture are different from those in the above embodiments. Specifically, the unlocking handle 33 is located on the side of the first arm 03 facing the second arm 04, the locking clamping piece 35 is located between the unlocking handle 33 and the first arm 03, and the unlocking handle 33 and the locking clamping piece 35 may be of an integrated structure or may be separately provided iron sheets. The force-applying handle 32 is linked with the force-applying clamping piece 34, such that when the force-applying handle 32 and the fixed handle 31 are gripped, the guide rod 05 is caused to slide, and the second arm 04 moves close to the first arm 03, and the unlocking handle 33 is linked with the locking clamping piece 35, such that when the unlocking handle 35 and the fixed handle 31 are gripped, the locking of the locking clamping piece 35 on the guide rod is released, so as to release the clamping.
With reference to FIGS. 11-14, the assembly manner of the fourth type of clamp also differs from the above embodiments, especially the assembly among the first arm 03, the base 14 and the force-applying handle 32. As shown in FIG. 13, the top of the first arm 03 is provided with a first mounting frame, the base 14 is accommodated in the first mounting frame, a side wall of the first mounting frame is provided with an avoidance opening, and a part of the first clamping body 01 extends into the base 14 after passing through the avoidance opening.

Both the second mounting frame and the plastic base 39 are provided with through holes for the guide rod 05 to pass through.
In the drawings, although the first clamping body and the second clamping body are determined by reference signs, but practical implementation is not limited to such representation forms, and the positions of the first clamping body and the second clamping body may be exchanged, and the concept of the present disclosure can also be embodied.
The present application further provides a clamping force visualization clamp combination device.
