Description

Technical Field

[0001] This utility model relates to the field of gearboxes, and more specifically, to a gearbox fixing clamp. Background Technology

[0002] A gearbox, also known as a speed reducer, is an independent component consisting of gear drives, worm drives, or gear-worm drives enclosed in a rigid housing. It is commonly used as a speed reduction transmission device between the prime mover and the working machine.

[0003] When machining a gearbox, a fixture is used to fix the outer shell, which facilitates operations such as drilling and grinding. Existing fixtures often fix the gearbox outer shell to the worktable, with the fixture in contact with the outer wall of the gearbox outer shell. However, the external dimensions of a gearbox vary depending on the requirements, and the shape and corners are often not completely symmetrical. Therefore, clamping by the outer wall requires the fixture to adapt to the shape of different gearbox outer shells. At the same time, the loading and unloading of gearbox outer shells often can only be done manually, followed by adjustment and handling, and unloading is also relatively inconvenient.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0025] The utility model will now be further described with reference to the accompanying drawings and specific embodiments:

[0026] Please see Figure 1-7A gearbox fixing fixture according to an embodiment of the present invention includes a worktable 1. Support legs 2 are fixedly installed on the bottom of the worktable 1. Horizontal sliding plates 3 are symmetrically installed along the center of the bottom of the worktable 1. The horizontal sliding plates 3 are arranged along the width direction of the worktable 1, and both ends of the horizontal sliding plates 3 extend beyond the sides of the worktable 1. Clamping components 4 are fixedly installed on the top of both ends of the horizontal sliding plates 3. A support component 5 is installed at the center of the top of the worktable 1. The gearbox to be processed is placed on the support component 5, and then the positions of the two horizontal sliding plates 3 are adjusted, thereby moving the clamping components 4. When the clamping components 4 contact the outer wall of the gearbox, the gearbox can be fixedly clamped.

[0027] The workbench 1 has extension plates 6 integrally formed on the center of the outer walls on both sides along its length. An adjusting cylinder 7 is fixedly installed at the bottom of one of the extension plates 6. The output shaft end of the adjusting cylinder 7 is fixedly connected to the bottom of the adjacent transverse plate 3. Activating the adjusting cylinder 7 will drive the transverse plate 3 connected to its output shaft to move and adjust.

[0028] The bottom of the worktable 1 is symmetrically equipped with slide rails 8 near both ends, and the slide rails 8 are arranged along the length of the worktable 1. The top of the transverse plate 3 is symmetrically equipped with a slide block 9, which is slidably mounted on the slide rail 8. A vertical shaft 10 is fixedly installed at the bottom center of the worktable 1, and a swing plate 11 is rotatably mounted on the vertical shaft 10. Connecting rods 12 are hinged to both ends of the swing plate 11, and the end of the connecting rod 12 away from the swing plate 11 is hinged to the corresponding transverse plate 3. When the adjusting cylinder 7 moves one side of the transverse plate 3, the moved transverse plate 3 will also drive the swing plate 11 to rotate around the vertical shaft 10 through the connected connecting rod 12. The vertical shaft 10 can then drive the connecting rod 12 at the other end to move synchronously, thereby realizing the synchronous movement operation of the other side of the transverse plate 3, realizing the mutual approach or separation of the two transverse plates 3, which facilitates the clamping of the gearbox on the support assembly 5.

[0029] The clamping assembly 4 includes a vertical frame 13, which is fixedly installed on the top of the transverse plate 3. A bushing 14 is fixedly installed through the top of the vertical frame 13, and a vertical shaft 15 is rotatably installed through the bushing 14. A right-angle frame 16 is fixedly installed at the top end of the vertical shaft 15, and a fixed shaft 17 is fixedly installed at both ends of the right-angle frame 16. A clamping wheel 18 is rotatably installed on the top of the fixed shaft 17. The two clamping wheels 18 at both ends of the same right-angle frame 16 can clamp the corners of the gearbox.

[0030] A first fixing nail 19 is fixedly installed at the top end of the upright frame 13 away from the bushing 14, and a second fixing nail 20 is fixedly installed at the bottom end of the right-angle frame 16 away from the first fixing nail 19. The first fixing nail 19 and the second fixing nail 20 are connected by a tension spring 21. A stop bar 22 is also fixedly installed on one side of the top of the upright frame 13, and the stop bar 22 is positioned away from the second fixing nail 20.

[0031] The support assembly 5 includes a fixed plate 23 fixedly installed at the top center of the workbench 1. An assembly base 24 is fixedly installed at the top center of the fixed plate 23. A rotating drum 25 is rotatably installed on the top of the assembly base 24. Two side frames 26 are symmetrically arranged along the center above the rotating drum 25. Several conveying rollers 27 are rotatably installed between the two side frames 26. A base plate 32 is fixedly installed at the bottom center between the two side frames 26. The bottom center of the base plate 32 is fixedly installed at the top end of the rotating drum 25. Placing the gearbox on the conveying rollers 27 facilitates loading and unloading. The rotating drum 25 allows the side frames 26 to be rotated, thereby changing the orientation of loading and unloading.

[0032] A sprocket 28 is installed at one end of the conveying roller 27. The sprocket 28 at the end of the conveying roller 27 is connected by a chain (transmission connection). An end plate 29 is fixedly installed at one bottom end of the frame 26. A motor 30 is installed at the bottom of the end plate 29. A reducer 31 is drivenly connected to the end of the output shaft of the motor 30. The reducer 31 is drivenly connected to the end of the conveying roller 27 that is close to it.

[0033] An outer protective sleeve 33 is also fixedly installed at the bottom of the base plate 32, and the outer protective sleeve 33 is sleeved on the outside of the rotating cylinder 25.

[0034] Through the above-described solution of this utility model, the structure of this utility model is simple and reasonable, quick and convenient to use, and can fix and clamp gearboxes of different specifications. Moreover, the right-angle frame 16 on the same clamping component 4 used to clamp the accelerator can rotate, so that the clamping wheel 18 can automatically fit according to the corner of the gearbox fixing fixture. The support component 5 used to support the gearbox fixing fixture can rotate, and the provided conveying roller 27 can facilitate loading and unloading of the gearbox fixing fixture.
