[0020] When the hydraulic pump production fixture of the present invention clamps and fixes the hydraulic pump, the bottom bracket 2, which is movably connected to the L-shaped fixture bracket 1, is removed, and the hydraulic pump to be clamped is placed on the bottom bracket 2, and then the bottom bracket 2 is pushed to reset. At this time, the hydraulic pump located on the bottom bracket 2 enters the clamping range of the first clamping seat 4 and the second clamping seat 5 of the first clamping mechanism. At this time, the first clamping seat 4 and the second clamping seat 5 are driven closer to each other by the clamping drive mechanism to clamp and fix the hydraulic pump from both sides. In order to enhance the fixing effect, the second clamping mechanism can be controlled by the lifting mechanism to move to the outside of one end of the hydraulic pump according to the height of the hydraulic pump, and then the movable rod 8 in the movable groove on the base 7 is pushed so that one end of the movable rod 8 is inserted into the slot 9 on the other side of the base 7. After the two sets of second clamping mechanisms perform the same operation, the second clamping mechanism is controlled by the lifting mechanism to move in the opposite direction a distance until the movable rod 8 presses and fixes the front end face of the hydraulic pump.

[0021] The clamping drive mechanism includes a bidirectional screw 10 and a connecting seat. The bidirectional screw 10 is rotatably provided in the mounting groove 3 and driven by a motor 11. The bidirectional screw 10 is symmetrically threaded with a connecting seat. The connecting seat is slidably connected to the mounting groove 3. One end of the first clamping seat 4 and the second clamping seat 5 are respectively connected to the two connecting seats. By starting the motor 11, the bidirectional screw 10 can be driven to rotate, and then the two connecting seats threadedly connected to the bidirectional screw 10 can be moved relative to each other, thereby driving the first clamping seat 4 and the second clamping seat 5 connected to the connecting seat to move relative to each other, thereby clamping or releasing the hydraulic pump.

[0022] The lifting mechanism includes a cylinder 12 and a guide rod 13. The cylinder 12 is disposed within the groove 6. Slide holes are provided on the first clamping seat 4 and the second clamping seat 5 on both sides of the groove 6. The guide rod 13 slides within the slide holes. One end of the guide rod 13 and the output end of the cylinder 12 are both connected to the bottom of the base 7. By activating the cylinder 12, the base 7 can be driven to move up and down, and during this process, the guide rod 13 can be activated to maintain the stability of the movement.

[0023] One end of the movable rod 8 on the base 7 of one set of the second clamping mechanisms is matched with the slot 9 on the base 7 of the other set of the second clamping mechanisms.

[0024] The bottom bracket 2 includes a movable base 201 and a supporting base 202. The L-shaped fixture bracket 1 is provided with a movable groove 14, within which the movable base 201 slides. The supporting base 202 is located on top of the movable base 201. One end of the movable base 201 extends beyond the movable groove 14 and is provided with a handle 203. By providing a movable bottom bracket 2 to support the hydraulic pump, loading and unloading the hydraulic pump is more convenient, unaffected by the first and second clamping bases 4 and 5 on either side, and thus easy to operate.

[0025] The utility model provides a second clamping mechanism on a first clamping seat 4 and a second clamping seat 5 which are driven to move relative to each other by a clamping drive mechanism. The base 7 of the second clamping mechanism can be moved by controlling the lifting mechanism. The movable rod 8 movably connected in the movable groove on the base 7 can be moved so that one end is inserted into the slot 9 on the base 7 of the other group of second clamping mechanisms. The two movable rods 8 can be used to limit and fix the end face of the hydraulic pump, and the other end face of the hydraulic pump can be positioned by the L-shaped tooling bracket 1, so that the hydraulic pump can be stably fixed, avoiding the problem of unstable fixation caused by a single form of fixation.
