[0039] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Fig. 9 As shown, the present invention provides a driving clamping device for a gear shaft grinder, comprising a gear shaft grinder frame 1, a discharging mechanism 2 is arranged on one side of the gear shaft grinder frame 1, a support plate 101 is fixedly connected to both ends of the top of the gear shaft grinder frame 1, a clamping rotating mechanism 3 is symmetrically arranged on the side of the support plate 101, and a gear shaft grinding mechanism 4 is installed on one side of the top of the gear shaft grinder frame 1;

[0040] A coordination and balancing mechanism 5 is installed on the top of the gear shaft grinder frame 1 , and a clamping mechanism 6 is installed in the middle of the top end of the gear shaft grinder frame 1 .

[0041] The unloading mechanism 2 includes a mounting base 201 and a mounting top seat 202 respectively arranged on the top and bottom of one side of the gear shaft grinder frame 1, and sliding rods 203 are fixedly connected to the top of the mounting base 201 and the bottom of the mounting top seat 202. One end of the mounting base 201 is movably connected to a folding frame 204, and the other end of the folding frame 204 is interlaced with the sliding rod 203. The bottom of the mounting base 201 is movably connected to a hydraulic telescopic rod 205, and a cross bar is movably connected between the telescopic end of the hydraulic telescopic rod 205 and the bottom end of the folding frame 204.

[0042] During specific use, after the processing of the T-piece 304 is completed, in order to facilitate the mechanical unloading of the heavier T-piece 304 and avoid damage caused by falling due to manual unloading, the hydraulic telescopic rod 205 on the top of the mounting base 201 is extended and retracted to push the cross bar at the bottom of the folding frame 204, so that the bottom end of the folding frame 204 slides back and forth on the sliding rod 203, thereby facilitating the continued adjustment of the horizontal height of the folding frame 204. At the same time, the top of the folding frame 204 slides on the sliding rod 203 at the bottom of the mounting base 201, so that the folding frame 204 can adjust its horizontal height, thereby facilitating the unloading of the T-piece 304.

[0043] The clamping rotating mechanism 3 includes a left working head feed spindle 301 fixedly connected to the side of the back plate 101, a first fixed mounting shell 302 is provided on one side of the left working head feed spindle 301, a first rotating servo 303 is fixedly connected to one side of the first fixed mounting shell 302, a T-piece 304 is provided on one side of the left working head feed spindle 301, a right working head feed spindle 305 is provided on one side of the T-piece 304, a second fixed mounting shell 306 is installed on one side of the right working head feed spindle 305, and a second rotating servo 307 is provided on one side of the second fixed mounting shell 306.

[0044] During specific use, in the grinding of shaft workpieces such as new energy shafts, the clamping position of T-piece 304 needs to be considered. If the entire T-piece 304 shaft needs to be processed, the T-piece 304 needs to be turned around because the clamping position needs to be avoided and cannot be completed in one go. Turning around will also cause repeated clamping, resulting in loss of precision and affecting the overall concentricity of the workpiece. The first rotary servo 303 and the second rotary servo 307 respectively drive the right working head feed spindle 305 and the left working head feed spindle 301 to feed the T-piece 304 to tighten the workpiece. The first rotary servo 303 and the second rotary servo 307 synchronously rotate and drive the T-piece 304. During grinding, no secondary clamping is required, and the grinding of the entire shaft is completed at one time. If there is no turning around, there is no concentric deviation. In addition, the mechanism is very suitable for automated occasions. There is no need for manual clamping of traction and rotation tools, automatic unloading, and automatic tightening and rotation of workpieces.

[0046] During specific use, when grinding the gear shaft, in order to evenly grind the T-piece 304, the rotation of the first drive motor 402 drives the first screw rod 403 to rotate, and the rotation of the first screw rod 403 makes it easier for the thread to drive the first movable seat 404 to move and slide on the slide rail 405. The left and right movement of the first movable seat 404 on the slide rail 405 makes it easier for the first servo motor 406 to drive the grinding cutter 407 to grind the T-piece 304.

[0048] During specific use, when the T-piece 304 is being balanced and ground, the first electric telescopic rod 505 at the bottom of the support column 501 is extended and retracted, so that the first electric telescopic rod 505 can adjust the adjustment arm 502 movably connected on the support column 501 when extending and retracting. By adjusting the adjustment arm 502, the rotating roller 504 of the mounting seat 503 is controlled to adjust the grinding and balanced rolling of the T-piece 304.

[0050] During specific use, when supporting and assisting the grinding of the T-piece 304, in order to prevent the T-piece 304 from falling off during material unloading and being unable to be clamped for loading, the handle 606 is manually turned to rotate the threaded screw 605 on one side of the handle 606, thereby facilitating the movable adjustment of the cross-folding frame 603 and the folding support adjustment of the cross-folding frame 603, thereby facilitating the rotating roller 607 to coordinate the support of the T-piece 304.

[0051] The top of the sliding rail 601 is slidably connected to the mobile frame 7, and the top of the mobile frame 7 is connected to the transverse adjustment frame 702 through the second electric telescopic rod 701.

[0052] During specific use, when adjusting and clamping the T-piece 304, the second electric telescopic rod 701 on the mobile frame 7 is extended and retracted to push the lateral adjustment frame 702, and the lateral adjustment frame 702 is adjusted. The extension and retraction of the third electric telescopic rod 703 facilitates the promotion of the longitudinal adjustment frame 704 for horizontal height adjustment, and facilitates the horizontal height adjustment of the clamping hand 709, thereby facilitating the clamping of the T-piece 304. The extension and retraction of the electric hydraulic cylinder 705 drives the moving slider 708 on the guide rod 707, so that the moving slider 708 can conveniently drive the clamping hand 709 to clamp the T-piece 304 during the movement.
