[0001] This invention relates to the field of gear machining for speed reducers, and more particularly to a clamping and fixing device for gear machining for speed reducers and its usage method. Background Technology

[0002] Clamping and fixing devices for gear reducer machining are key equipment for ensuring precise positioning and stability of gears during the gear manufacturing process. These devices are designed to firmly clamp the gear workpiece during cutting, grinding, and inspection, preventing vibration and displacement and ensuring machining accuracy. However, existing clamping and fixing devices for gear reducer machining cannot grind the cut gears; they must be transferred to grinding equipment after cutting, resulting in low machining efficiency and high processing costs.

[0003] Therefore, a clamping and fixing device for gear reduction gear processing and its usage method have been developed that can grind the workpiece while cutting, thereby improving workpiece processing efficiency and saving costs. Summary of the Invention

[0004] To overcome the shortcomings of existing clamping and fixing devices for gear reduction gear processing, which cannot grind the cut gears and require them to be transferred to grinding equipment after cutting, resulting in low gear processing efficiency and high processing costs, this invention provides a clamping and fixing device for gear reduction gear processing and its usage method that can grind the workpiece while cutting, thereby improving workpiece processing efficiency and saving costs.

[0005] The technical solution of the present invention is: a clamping and fixing device for machining reducer gears and its usage method, comprising a worktable, a collection box and a bidirectional lead screw, wherein the collection box is placed on the upper side of the middle part of the worktable and the bidirectional lead screw is rotatably connected to the front part of the worktable.

A grinding block is connected to the guide plate. An oil injection pipe is connected to the upper side of the first fixture.

[0010] Furthermore, it also includes a second clamp, a second movable fixing frame, a second motor and a first gear. The second clamp is threadedly connected to the left side of the bidirectional lead screw. The rear of the second clamp is slidably connected to the worktable.

[0012] Furthermore, it also includes the following steps:

[0013] S1: Engage the workpiece with the rotating connecting column, then place the fixed column between the first movable fixed frame and the second movable fixed frame, and then rotate the bidirectional screw by the handle to bring the first clamp and the second clamp closer to each other, thereby bringing the first movable fixed frame and the second movable fixed frame closer to each other to clamp the fixed column.

[0014] S2: Adjust the positions of the first and second movable fixing frames according to the position of the workpiece, drive the rotating connecting column to move so that the workpiece is below the workpiece. After adjustment, the workpiece will cut the workpiece into the shape of a gear.

[0015] S3: Rotate the workpiece to be cut to the grinding block. Through the action of the spring, the grinding block is embedded in the workpiece to be cut. Then start the first motor to drive the one-way lead screw to rotate, which moves the moving block and the guide plate, so that the grinding block moves in the workpiece to grind the workpiece.

[0016] The beneficial effects are: the present invention uses the force of the spring to make the grinding block embed into the cutting part of the workpiece, and then starts the first motor to drive the one-way lead screw to rotate, which moves the moving block and drives the guide plate to move, so that the grinding block moves in the workpiece.

[0029] like Figure 4 and Figure 5 As shown, it also includes a first motor 51, a one-way lead screw 52, ​​a moving block 53, a guide plate 54, springs 55, grinding blocks 56, and an oil injection pipe 57. The first motor 51 is connected to the left rear part of the first clamp 5. The one-way lead screw 52 is connected to the output shaft of the first motor 51. The front side of the one-way lead screw 52 is rotatably connected to the first clamp 5. The moving block 53 is threadedly connected to the one-way lead screw 52. The moving block 53 is slidably connected to the first clamp 5. The guide plate 54 is slidably connected to the moving block 53. Three springs 55 are connected between the guide plate 54 and the moving block 53. The grinding block 56 is connected to the guide plate 54. The oil injection pipe 57 is connected to the upper side of the first clamp 5.

[0030] like Figure 1 , Figure 3 and Figure 6 As shown, it also includes a second clamp 6, a second movable fixing frame 60, a second motor 61, and a first gear 62. The left side of the bidirectional lead screw 4 is threadedly connected to the second clamp 6. The rear of the second clamp 6 is slidably connected to the worktable 1. The right side of the second clamp 6 is slidably connected to two second movable fixing frames 60. The second motor 61 is connected to the rear second movable fixing frame 60. The first gear 62 is connected to the output shaft of the second motor 61. A fixing component 7 is provided between the first movable fixing frame 50 and the second movable fixing frame 60.

[0031] like Figure 1 , Figure 3 and Figure 7 As shown, it also includes a fixing component 7, which includes a workpiece 70, a rotating connecting column 71, a fixing column 72, and a second gear 73.

[0032] When using this invention, firstly, place the workbench 1 in the gear machining area of ​​the reducer, then engage the workpiece 70 with the rotating connecting column 71, and then place the fixing column 72 between the first movable fixing frame 50 and the second movable fixing frame 60. Next, rotate the double-acting screw 4 using the handle 3 to bring the first clamp 5 and the second clamp 6 closer together, causing the first movable fixing frame 50 and the second movable fixing frame 60 to move closer together and clamp the fixing column 72.

When the workpiece 70 rotates, the part of the workpiece 70 to be cut rotates to the grinding block 56. Through the force of the spring 55, the grinding block 56 is embedded in the part of the workpiece 70 to be cut. Then the first motor 51 is started, which drives the one-way lead screw 52 to rotate, so that the moving block 53 moves, and drives the guide plate 54 to move, so that the grinding block 56 moves in the workpiece 70. This achieves the effect of grinding the workpiece 70 at the same time as cutting, improving the processing efficiency of the workpiece 70 and saving costs. When the grinding block 56 grinds the workpiece 70, the oil spray pipe 57 can spray oil to lubricate the workpiece 70.
