[0022] As Figures 1-3 shown, it relates to a processing fixture for a gear chamber cover, including an N-type base 1, multiple groups of clamping assemblies 4 and multiple groups of supporting assemblies 7. The number of each group of clamping assemblies 4 is two. Two symmetrical strip-shaped grooves 2 are opened at the top of the N-type base 1. Transverse movement assemblies 3 are slidably connected inside both of the two strip-shaped grooves 2. Each group of two clamping assemblies 4 can be fixedly connected to the two transverse movement assemblies 3 respectively. A driving assembly 5 for driving the two transverse movement assemblies 3 to move synchronously is provided inside the bottom end of the N-type base 1. A placing groove 6 for installing the supporting assembly 7 is opened in the middle of the upper surface of the N-type base 1.

[0023] Mounting plates 8 are fixedly provided on both sides of the bottom end of the N-type base 1, and mounting holes are opened on the mounting plates 8.

[0024] The mounting plates 8 can be fixedly installed on the surface of the milling machine through the mounting holes.

[0025] Each group of supporting assemblies 7 includes a positioning plate 71, and the positioning plate 71 can be clamped inside the placing groove 6. A plurality of supporting columns 72 for supporting the gear chamber cover are fixed on the surface of the positioning plate 71. The heights of the supporting columns 72 of each group of supporting assemblies 7 are different.

[0026] When fixing the fixed gear chamber cover, it can be placed on the tops of multiple support columns 72. The support columns 72 are used to support the gear chamber cover, and the gear chamber cover is ensured to be horizontal. Different gear chamber covers can be supported by different support components 7, and the support components 7 can be directly taken out from the placement groove 6. During installation, the positioning plate 71 of the support component 7 can be directly placed inside the placement groove 6.

[0027] The transverse movement component 3 includes a slider 31 slidably connected to the strip-shaped groove 2. A second rack 34 is fixed to the lower surface of the slider 31. The inside of the second rack 34 is hollow-designed. A guide rod 35 penetrates and is slidably connected inside the second rack 34. One end of the guide rod 35 is fixedly connected to the inner wall of the N-shaped base 1.

[0028] The second rack 34 can drive the slider 31 to move along the strip-shaped groove 2, and the guide rod 35 plays a supporting role for the second rack 34.

[0029] The driving component 5 includes a vertical shaft 51 and a hydraulic telescopic rod 52 fixed to the inner side wall of the N-shaped base 1. A first rack 53 is fixed to the telescopic end of the hydraulic telescopic rod 52. The top end of the vertical shaft 51 is rotatably connected to the inner top wall of the N-shaped base 1 through a bearing. A driving gear 54 and a driven gear 55 are fixed to the surface of the vertical shaft 51. The first rack 53 meshes with the driving gear 54, and the driven gear 55 meshes with the two second racks 34.

[0030] When the hydraulic telescopic rod 52 drives the first rack 53 to move, the first rack 53 will drive the driving gear 54 to rotate. The driving gear 54 then drives the vertical shaft 51 to rotate. Then, the driven gear 55 drives the two second racks 34 to move synchronously, and the moving directions of the two second racks 34 are opposite, thereby realizing the mutual approach or separation of the two sliders 31 in the strip-shaped groove 2.

[0031] A slot 32 is opened at the top of the slider 31. A magnet 33 is fixed to the inner bottom wall of the slot 32. The clamping component 4 includes a clamping plate 41, and an iron sheet 42 is fixed to the bottom end of the clamping plate 41. The bottom of the clamping plate 41 can be inserted into the slot 32. The heights of the clamping plates 41 of each group of clamping components 4 are different.

[0032] In this embodiment, the clamping plate 41 is fixed in the slot 32 by the attraction of the magnet 33 and the iron sheet 42. When the slider 31 moves along the strip-shaped groove 2, the clamping plate 41 can be driven to move synchronously. When the two clamping plates 41 approach each other under the drive of the driving component 5, the two clamping plates 41 can clamp and fix the gear chamber cover from the side of the gear chamber cover. For different types of gear chamber covers, the clamping component 4 in the slot 32 can be disassembled and replaced to ensure that the top end of the clamping plate 41 is lower than the end face of the gear chamber cover when the clamping plate 41 clamps the gear chamber cover, so that the end face milling of the gear chamber cover will not be affected.

[0033] A rubber pad is fixed on the surface of the clamping plate 41. By providing the rubber pad, the clamping plate 41 can protect the gear chamber cover when clamping it.

[0034] Working principle: For the gear chamber cover to be processed, select a corresponding set of clamping components 4 and install them on the tops of the two sliders 31. Then select a corresponding set of support components 7 and place them inside the placement groove 6. Next, place the gear chamber cover on the tops of the support components 7. After the gear chamber cover is placed, start the hydraulic telescopic rod 52 to drive the sliders 31 of the two transverse movement components 3 to approach each other, thereby driving the two clamping plates 41 to clamp and fix the gear chamber cover.
