For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, indirect connection through an intermediate medium, internal communication between two components, or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0027] The utility model provides a technical solution:

[0028] Example 1

[0029] Combine Figures 1 to 5 A gearbox processing fixture includes a base 3, a clamping mechanism 1 is provided on the top of the base 3, and a positioning mechanism 2 is provided on the outside of the clamping mechanism 1;

[0030] The clamping mechanism 1 includes a flip assembly 11 , a clamping assembly 12 and a limit assembly 13 . The flip assembly 11 is arranged on the left and right sides of the top of the base 3 , the clamping assembly 12 is arranged inside the flip assembly 11 , and the limit assembly 13 is arranged outside the clamping assembly 12 .

[0031] The flip assembly 11 includes a support frame 1101, which is fixedly connected to the left and right sides of the top of the base 3. A turntable 1102 is rotatably connected to the top of the support frame 1101, a cam 1103 is fixedly connected to the turntable 1102, and a fixed screw barrel 1104 is fixedly connected to the cam 1103. The clamping assembly 12 includes a threaded shaft 1201, which is threadedly connected to the inner ring of the fixed screw barrel 1104, and a torsion disc 1202 is fixedly connected to the outer side of the threaded shaft 1201. The inner side of the shaft 1201 is rotatably connected to a splint 1203, and the inner side of the splint 1203 is fixedly connected to a protrusion 1204. The limiting assembly 13 includes a limiting slide 1301, which is fixedly connected to the outer side of the splint 1203. The inner side of the outer ring of the limiting slide 1301 is fixedly connected to a pad 1302, and the pad 1302 is fixedly connected to the outer side of the splint 1203. The outer side of the limiting slide 1301 is fixedly connected to a connecting frame 1303, and the connecting frame 1303 is sleeved on the outer ring of the threaded rotating shaft 1201.

[0032] Furthermore: the staff only needs to rotate the torsion plate 1202 to drive the splint 1203 to move inward, so that the splints 1203 on the left and right sides cooperate with the protrusion 1204 to complete the clamping of the gear box body. Since the splints 1203 on the left and right sides are independently controlled, the staff can control the position deviation of the gear box after it is fixed by adjusting the distance that the splints 1203 on the left and right sides move inward. At the same time, since the turntable 1102 is rotatably connected to the top of the support frame 1101, the staff can flip the fixed gear box as needed, so that after the device fixes the gear box, the staff can still adjust the position relationship of the gear box, which is convenient for the staff to process and handle it later and convenient for the staff to use.

[0033] Example 2

[0034] See Figure 1 、 Figure 2 、 Figure 3 and Figure 5 , and on the basis of Example 1, it is further obtained that the positioning mechanism 2 includes a reset component 21, a positioning component 22 and a pulling component 23, the reset component 21 is arranged on the outside of the flip component 11, the positioning component 22 is arranged above the reset component 21, and the pulling component 23 is arranged on the front and rear sides of the reset component 21.

[0035] The reset assembly 21 includes a fixed cylinder 2101, which is fixedly connected to the outer side of the support frame 1101. A rectangular slide 2102 is slidably connected to the fixed cylinder 2101. A compression spring 2103 is fixedly connected to the top of the rectangular slide 2102. The compression spring 2103 is fixedly connected to the bottom of the fixed cylinder 2101. The positioning assembly 22 includes a clamping block 2201, which is fixedly connected to the top of the rectangular slide 2102. A positioning sleeve 2202 is clamped on the top of the clamping block 2201. The positioning sleeve 2202 is fixedly connected to the outer side of the turntable 1102. The pulling assembly 23 includes a movable slide 2301, which is fixedly connected to the front and rear sides of the rectangular slide 2102. The movable slide 2301 is slidably connected to the front and rear sides of the fixed cylinder 2101. The inner circle of the movable slide 2301 is rotatably connected to the pull rod 2302, and the pull rod 2302 is sleeved on the outer side of the fixed cylinder 2101.

[0036] Furthermore: the rectangular slide 2102 drives the block 2201 to always maintain the force of moving upward under the action of the compression spring 2103, so that the block 2201 is engaged with the bottom of the outer ring of the positioning sleeve 2202 to complete the positioning of the turntable 1102, so that the staff can position the turntable 1102 at any angle during the rotation of the turntable 1102, thereby increasing the stability of the device during use.

[0037] In actual operation, when this device is used, when the gear box needs to be clamped, the staff rotates the torsion plates 1202 on both sides, and the rotation of the torsion plates 1202 drives the threaded shaft 1201 to rotate, and the threaded shaft 1201 rotates on the inner ring of the fixed screw cylinder 1104 to move inward, and the inward movement of the threaded shaft 1201 drives the clamping plates 1203 and the protrusion 1204 to move inward until the distance between the left and right clamping plates 1203 is slightly larger than the side length of the gear box. After that, the staff places the gear box between the left and right clamping plates 1203, and then rotates the left and right torsion plates 1202 again to move the left and right clamping plates 1203 inward until the limit is reached. At this time, the clamping process of the gear box is completed;

[0038] When it is necessary to flip the clamped gearbox, the staff first pulls the pull rods 2302 on the left and right sides to move downward. The pull rods 2302 move downward and drive the rectangular slide 2102 to move downward through the moving slide 2301. The rectangular slide 2102 moves downward and drives the block 2201 to move downward. The block 2201 moves downward and retracts into the fixed cylinder 2101 to release the connection with the positioning sleeve 2202. Then the staff can rotate the turntable 1102 to control the gearbox to flip. After the flipping angle is appropriate, the staff releases the limit of the pull rods 2302 on the left and right sides. At this time, the rectangular slide 2102 drives the block 2201 to move upward under the action of the compression spring 2103. The block 2201 moves upward and is clamped in the outer ring of the positioning sleeve 2202. At this time, the positioning process of the turntable 1102 is completed, and the angle flipping process of the clamped gearbox is completed.
