Gears refer to mechanical elements that transmit motion and torque through the meshing between gears. They are composed of a certain number of gears. The gearbox is a composite mechanical structure composed of multiple stages of gears. Gears of various sizes are combined and meshed to achieve transmission in different proportions.

[0003] However, it still has the following disadvantages in actual use:

[0004] When the existing press-in jig is used by the staff, the press-in jig needs to be welded and installed on the processing mechanism in advance to achieve the function of auxiliary processing. When the press-in jig fails, the staff needs to disassemble it. The whole operation process is inconvenient and cumbersome, which delays the work progress of the staff. Utility Model Content

[0027] See also Figure 1-4 As shown, this embodiment is a press-in fixture for a gear box gear assembly, including a placement plate 1, a fixing frame 2 is installed above the placement plate 1, a mounting plate 6 is installed above the placement plate 1, and also includes a mounting mechanism: the mounting mechanism includes a mounting plate 6 arranged below the placement plate 1, a knob 8 is rotatably connected to the outer surface of the mounting plate 6, one end of the knob 8 is fixedly connected to a connecting rod 11, one end of the connecting rod 11 is threadedly connected to a clamping block 7, and a guide assembly is provided on one side of the clamping block 7; a positioning mechanism: the positioning mechanism is arranged above the placement plate 1.

[0028] The mounting mechanism serves as the main bearing structure and can increase the installation stability of the entire structure by being installed integrally with the device.

[0029] Furthermore, the guide assembly includes a guide block 10 arranged on one side of the clamping block 7 , and a slide groove 9 is provided at the bottom end of the placement plate 1 .

[0030] The guide assembly is arranged to prevent the clamp block 7 from rotating with the rotation of the connecting rod 11, thereby playing a guiding role.

[0031] Furthermore, the reset assembly includes a compression spring 13 arranged on the outer surface of the sleeve rod 16 , and there are two groups of support frames 14 , which are located at both ends of the compression spring 13 .

[0032] The reset assembly is arranged so that after the sleeve blocks 3 are squeezed and the force disappears, the two sets of sleeve blocks 3 can be automatically reset.

[0033] Furthermore, the outer surface of the connecting rod 11 is provided with a thread, the inside of the clamping block 7 is provided with a thread groove, the inside of the mounting plate 6 is provided with an empty groove 12, and the inside of the empty groove 12 is penetrated by the connecting rod 11.

[0034] The arrangement of the thread and the thread groove can enable the connecting rod 11 to rotate and drive the clamping block 7 to slide.

[0035] Working principle: After the fixture is placed at the installation location, by simultaneously rotating the knobs 8 on both sides of the installation plate 6, the knobs 8 can be rotated to drive the connecting rod 11 fixedly connected at one end to rotate, so that the clamping block 7 threadedly connected to one end of the connecting rod 11 is displaced, and at the same time, the guide block 10 installed at one end of the clamping block 7 slides along the guide track of the slide groove 9, so that the two groups of clamping blocks 7 clamp and position the installation location to achieve the purpose of installation.

[0036] See also Figure 1-4 As shown, this embodiment is based on the above-mentioned embodiment 1 and further includes: a positioning mechanism is arranged on a support frame 14 above the placement plate 1, a cylinder 4 is installed above the support frame 14, a sleeve rod 16 is installed on the inner side of the fixed frame 2, the outer surface of the sleeve rod 16 is slidably connected with a sleeve block 3, a clamping block 5 is installed above the sleeve block 3, a reset component is arranged on the outer surface of the sleeve rod 16 located on the inner side of the sleeve block 3, and a limiting component is arranged on one side of the fixed frame 2 located below the sleeve block 3.

[0037] Furthermore, the limiting assembly includes a guide rail 15 arranged on one side of the fixing frame 2 , and the sleeve block 3 is slidably connected above the guide rail 15 .

[0038] The setting of the limit assembly can enable the sleeve block 3 to slide and guide along the upper side of the guide rail 15 .

[0039] Working principle: before putting the gear assembly into the cylinder 4, the staff slides the sleeve block 3 on the outer surface of the sliding sleeve rod 16 to make the sleeve block 3 slide along the guide track of the guide rail 15, so that the two sets of sleeve blocks 3 squeeze the compression spring 13, thereby shrinking the block 5 installed on the compression spring 13. At this time, the gear assembly is put into the cylinder 4, and the squeezing of the sleeve block 3 is released at the same time, so that the two sets of block blocks 5 are reset and the gear assembly is positioned. When taking the pressed gear, the above reverse steps can be directly applied;

[0040] This step can facilitate the staff to perform positioning operations and prevent the gear assembly from shifting during the press-fitting process.
