FIELD OF THE INVENTION
The present invention relates to a deceleration device for a power turret clutch, particularly to using a single transmission shaft to output two types of dynamic power having different rotation speeds respectively driving different mechanical units.
BACKGROUND OF THE INVENTION
In a multi-functional machine, a machine is equipped with a plurality of cutting seats accommodating different types of cutting tools, and the cutting tools can be automatically shifted to perform required machining.
In the conventional multi-functional machines, two motors respectively supply dynamic power to rotate the principal shaft and shift the cutting seats. Thus, the conventional multi-functional machines are usually bulky and expensive. However, the current trend is toward miniaturizing the multi-functional machines.
SUMMARY OF THE INVENTION
The primary objective of the present invention is to utilize a single dynamic power to support the rotation of the principal shaft and the shifting of the cutting seats.
To achieve the abovementioned objective, the present invention proposes a deceleration device for a power turret clutch, which comprises a deceleration gear assembly, a slide gear shaft, a displacement driving unit, and a transmission spindle, wherein the slide gear shaft has a gear, and the displacement driving unit drives the slide gear shaft to slide axially and reach a first position and a second position. When sliding to the first position, the slide gear shaft engages with a spindle connector. When sliding to the second position, the slide gear shaft disengages with the spindle connector and engages with the deceleration gear assembly. The transmission spindle drives the slide gear shaft to rotate and supplies dynamic power to the slide gear shaft.
The present invention is characterized in that a single transmission spindle provides dynamic power for the rotation of the shaft and the shifting of the cutting seats. Therefore, the present invention can greatly reduce the volume and cost of a multi-functional machine.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Below, technical contents of the present invention are described in detail with the embodiments. However, it should be understood that the embodiments are only to exemplify the present invention but not to limit the scope of the present invention.
Refer to FIG. 1, FIG. 2A and FIG. 2B. The deceleration device for a power turret clutch of the present invention comprises a deceleration gear assembly 10, a slide gear shaft 20, a displacement driving unit 30, and a transmission spindle 40. The slide gear shaft 20 has a gear 21, and the displacement driving unit 30 drives the slide gear shaft 20 to slide axially and reach a first position (as shown in FIG. 2A) and a second position (as shown in FIG. 2B). The displacement driving unit 30 is a hydraulic unit 31 having a first chamber 311 and a second chamber 312. When liquid is respectively injected into the first chamber 311 and the second chamber 312, the slide gear shaft 20 is driven to slide. Alternatively, the displacement driving unit 30 may be a pneumatic cylinder or an electromagnetic device, and the slide gear shaft 20 is pneumatically or electromagnetically driven to slide.
The transmission spindle 40 is arranged around the slide gear shaft 20 to form an internal motor. Alternatively, the transmission spindle 40 may be coupled to an external motor, and the external motor drives the transmission spindle 40 to rotate, and the transmission spindle 40 further drives the slide gear shaft 20 to rotate. Refer to FIG. 3, FIG. 4 and FIG. 5. The transmission spindle 40 is a hollow structure having an inner gear 41. The slide gear shaft 20 has an outer gear 23 corresponding to the inner gear 41. Via the engagement of the inner gear 41 and the outer gear 23, dynamic power is transmitted from the transmission spindle 40 to the slide gear shaft 20. The engagement of the transmission spindle 40 and the slide gear shaft 20 may also be realized with a six-wedge mechanism (as shown in FIG. 4) or a single-bayonet mechanism (as shown in FIG. 5).
Refer to FIG. 6 and FIG. 7. The deceleration gear assembly 10 is a planetary gear assembly 11 engaging with a rotational wheel device 12. The rotational wheel device 12 has a static wheel 121 and a rotary wheel 122. The static wheel 121 sleeves the rotary wheel 122, and a bearing 13 interposes between the static wheel 121 and the rotary wheel 122. The rotary wheel 122 has a plurality of installation holes 123 and an internal annular gear 124. The internal annular gear 124 engages with the planetary gear assembly 11. The edges of the static wheel 121 and the rotary wheel 122 respectively have fixing trenches 125 matching each other. A fastening element 126 (as shown in FIG. 11) is press-fitted to the fixing trenches 125 to fix the relative position of the static wheel 121 and the rotary wheel 122.
Refer to FIG. 8, FIG. 9A and FIG. 9B. A spindle connector 50 has a bevel gear seat 51, a slide connection rod 52, a bevel gear shaft 53 and a bevel gear 54. The bevel gear 54 and the bevel gear shaft 53 are rotatably installed inside the bevel gear seat 51, and engaged to each other by different directions of transmission. The bevel gear shaft 53 has an inner gear 531 engaging with the gear 21. The bevel gear 54 sleeves the slide connection rod 52 and rotates synchronously with the slide connection rod 52. The slide connection rod 52 slidably contacts the bevel gear seat 51. A displacement driving unit 55 drives the slide connection rod 52 to slide. The edge of the slide connection rod 52 has an inner transmission gear 522. The displacement driving unit 55 is a hydraulic unit, and liquid is injected to a chamber 551 to drive the slide connection rod 52 to slide (as shown in FIG. 9B).
Refer to FIG. 10, FIG. 11 and FIG. 12. FIG. 10 is a perspective view schematically showing the installation of cutting tools 60 and a casing 70. The gear 21 is arranged in the terminal of the slide gear shaft 20. The spindle connector 50 has the inner gear 531 exactly facing the terminal of the slide gear shaft 20. The circumference of the slide gear shaft 20 has an annular trench 22. The deceleration gear assembly 10 is arranged around the slide gear shaft 20. When the slide gear shaft 20 slides to the first position, the gear 21 engages with the inner gear 531 of the spindle connector 50, and the deceleration gear assembly 10 is located in the annular trench 22. When the slide gear shaft 20 slides to the second position, the gear 21 withdraws from the inner gear 531 of the spindle connector 50 and engages with the deceleration gear assembly 10.
In conclusion, the present invention uses a single motor to provide dynamic power for the rotation of the shaft and the shifting of the cutting seats. Further, the present invention uses a novel transmission structure to stably transmit dynamic power and promote the stability of the machine. Therefore, the present invention can greatly reduce the volume and cost of a machine and effectively promote the machining quality thereof.
