The present invention relates to a grinding block technique, particularly to a grinding block suitable for different radians.
Grinding blocks are used to smooth rough surface of products and widely used in some hardware and plastic products. However, existing grinding blocks still have the following shortcomings when used: At present, flat grinding blocks and curved grinding blocks can be provided in the market. When different surfaces (flat and curved) are to be ground together, we have to change the blocks frequently, however, curved surfaces may not match, wasting a lot of time in finding suitable curved grinding discs and accordingly reducing the efficiency. In addition, different types of curved grinding discs are required, resulting in high cost, low efficiency and unsatisfactory effects. Therefore, a suitable grinding block suitable for different radians is proposed to solve the above issues.
In order to solve the above issues, the present invention provides the following technical solution: A grinding block suitable for different radians, which comprises a grinding block body and has at least one internal soft shaft; Connecting grooves are set on both sides of the grinding block body, and a grinding surface is set at the bottom.
As a preferred technical solution of the present invention, the soft shaft comprises a soft shaft body and a stable shaft fit at both ends of the stable shaft.
As a preferred technical solution of the present invention, a positioner is provided at a stable shaft end away from the soft shaft body.
As a preferred technical solution of the present invention, several Positioning Ribs I are evenly and circularly spaced in the soft shaft body.
As a preferred technical solution of the present invention, the interior of the soft shaft body is further provided with limit ring ribs inside the Positioning Ribs I, and the number of the limit ring ribs should be at least one.
As a preferred technical solution of the present invention, Positioning Ribs II are set in the stable shaft.
As a preferred technical solution of the present invention, both ends of the soft shaft body are internally provided with moving grooves, and a stable shaft end away from the positioner extends to the interior of the moving grooves.
As a preferred technical solution of the present invention, a moving cavity is provided inside the grinding block body, and the soft shaft body is movably fit inside the moving cavity.
As a preferred technical solution of the present invention, both ends of the moving cavity are provided with a limit cavity, and the positioner is fastened to the limit cavities.
As a preferred technical solution of the present invention, the outer diameter of the positioner is higher than that of the soft shaft body.
Compared with the prior art, the present invention provides a grinding block suitable for different radians, which has the following beneficial effects: This grinding block is suitable for different radians; By setting the soft shaft in the grinding block body and supporting the bent grinding block body with the soft shaft, the stability of the grinding block body after bending and deformation can be ensured. By using the stable shaft, the stability of the two ends of the grinding block body and a wide bending angle range after deformation can be ensured, which is more fitted to the shapes of products to be ground. Therefore, it is unnecessary for users to purchase grinding blocks with different shapes, reducing the usage cost and meeting users' requirements.

According to
As a specific technical solution of the present embodiment, the soft shaft 2 comprises a soft shaft body 21 and a stable shaft 22 fit at both ends of the stable shaft 22; The soft shaft body 21 and stable shaft 22 are both made of soft plastic and mainly used to wrap Positioning Ribs I 24 and Positioning Ribs II 26; As shown in
As a specific technical solution of the present embodiment, a positioner 23 is provided at a stable shaft 22 end away from the soft shaft body 21.
As a specific technical solution of the present embodiment, several Positioning Ribs I 24 are evenly and circularly spaced in the soft shaft body 21; The Positioning Ribs I 24 are made of fine metal wires such as copper wires, aluminum wires, iron wires and can be bent and positioned arbitrarily.
As a specific technical solution of the present embodiment, the interior of the soft shaft body 21 is further provided with limit ring ribs 25 inside the Positioning Ribs I 24, and the number of the limit ring ribs 25 should be at least one; The limit ring ribs 25 are made of carbon steel and can be used for shaping inside the soft shaft body 21, preventing the moving grooves 27 from being pressed flat. As shown in

As a specific technical solution of the present embodiment, both ends of the soft shaft body 21 are internally provided with moving grooves 27, and a stable shaft 22 end away from the positioner 23 extends to the interior of the moving grooves 27; When the grinding block body 1 is bent, the distance between the two ends of the soft shaft body 21 and the two ends of the moving cavity 13 increases; The setting of the stable shaft 22 can help to fill the gap between the two ends of the soft shaft body 21 and the two ends of the moving cavity 13; This design allows the two ends of the bent grinding block body 1 to always keep a good shaping thanks to the stable shaft 22.
As a specific technical solution of the present embodiment, a moving cavity 13 is provided inside the grinding block body 1, and the soft shaft body 21 is movably fit inside the moving cavity 13.
As a specific technical solution of the present embodiment, both ends of the moving cavity 13 are provided with a limit cavity 14, and the positioner 23 is fastened to the limit cavities 14; The outer diameter of the positioner 23 is higher than that of the soft shaft body 21; The limit cavities 14 can lock the positioner 23, preventing the positioner 23 from moving left and right inside the moving cavity 13 and making it always support the two ends of the grinding block body 1.
In summary, this grinding block is suitable for different radians; By setting the soft shaft 2 in the grinding block body 1 and supporting the bent grinding block body 1 with the soft shaft 2, the stability of the grinding block body 1 after bending and deformation can be ensured. By using the stable shaft 22, the stability of the two ends of the grinding block body 1 and a wide bending angle range after deformation can be ensured, which is more fitted to the shapes of products to be ground.
