One end of the threaded rod located on the outer side of the positioning platform is fixedly connected to a knob. The inner side of the arc-shaped slider is fixedly connected to a hinge block. When processing the gear, the inner edge of the gear is aligned with the triangular block and pressed downward, so that the inner edge of the gear contacts the triangular block and forces the connecting rod and the hinge block to rotate. A connecting rod passes through and is hinged on the inner side of the hinge block. The top surface of the connecting rod is fixedly connected to the triangular block. The moving block will drive the connecting rod to move together through the hinge block, thereby shortening the distance between the three groups of connecting rods. Reverse rotation will increase the distance between the connecting rods to adapt to the processing of gears of different sizes.

[0008] Preferably, the number of the arc-shaped sliding blocks is three groups, and arc-shaped rods penetrate between the three groups of arc-shaped sliding blocks, and arc-shaped springs are fixedly connected between every two groups of arc-shaped sliding blocks.

[0009] Preferably, a support rod is passed through and slidably connected to the top surface of the fixed block, and a placement plate is fixedly connected to the top surface of the support rod.

The connecting rod will tighten the torsion spring after rotation. When the top end of the gear exceeds the bottom end of the triangular clamping block, the tightened torsion spring will pull back the connecting rod to drive the triangular clamping block to clamp the top of the gear, so that the connecting rod clamps the inner edge of the gear.

[0014] Compared with the prior art, the utility model provides a gear positioning device for machining gears, which has the following beneficial effects:

[0015] 1. The gear positioning device for processing gears, when the top end of the gear exceeds the bottom end of the triangular clamping block, the tightened torsion spring will pull back the connecting rod to drive the triangular clamping block to clamp the top of the gear, so that the connecting rod clamps the inner edge of the gear, and when the gear is pressed downward, the placement plate will be pressed downward and the support rod will be pushed downward, and the second spring will be compressed. When the gear is clamped under the triangular clamping block, not only will the torsion spring clamp the inner edge of the gear by pulling back the connecting rod, but the compressed second spring will also push the placement plate to lift the gear to be processed, so that the bottom of the gear is clamped with the placement plate, and the triangular clamping block is clamped with the top of the gear, so that the gear is positioned more tightly and the gear teeth can be prevented from being worn during gear processing.

The moving block will drive the connecting rod to move together through the hinge block, shortening the distance between the three groups of connecting rods. Reverse rotation will increase the distance between the connecting rods to adapt to the processing of gears of different sizes. The adjustment is convenient and simple, and the adaptability is strong. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] like Figure 1-Figure 4 As shown, the utility model provides a technical solution: a gear positioning device for processing gears, including a positioning platform 1, a positioning part 2 is arranged inside the positioning platform 1, and the positioning part 2 includes: a fixed block 21, an active cavity 22, an arc-shaped slider 23, a moving block 24, a slide groove 25, a threaded rod 26, a knob 27, a hinge block 28, a connecting rod 29, a triangular clamping block 210, a torsion spring 211, an arc-shaped rod 212, an arc spring 213, a support rod 214, a placement plate 215, a limiting groove 216, and a spring 217.

[0023] The fixed block 21 is fixedly connected to the inner wall of the positioning platform 1, and a movable cavity 22 is provided on the bottom surface of the fixed block 21. An arc-shaped slider 23 is slidably connected to the inner side of the movable cavity 22, and a moving block 24 is fixedly connected to the bottom surface of the arc-shaped slider 23. A slide groove 25 is provided on the inner wall of the positioning platform 1, and the moving block 24 passes through the slide groove 25 and is slidably connected. The threaded rod 26 passes through the positioning platform 1 and is rotatably connected. A knob 27 is fixedly connected to one end of the threaded rod 26 located on the outer side of the positioning platform 1, and a hinge block 28 is fixedly connected to the inner side of the arc-shaped slider 23. When processing the gear When the inner edge of the gear is aligned with the triangular block 210 and pressed downward, the inner edge of the gear contacts the triangular block 210 and forces the connecting rod 29 and the hinge block 28 to rotate. The inner side of the hinge block 28 is penetrated and hinged with the connecting rod 29, and the top surface of the connecting rod 29 is fixedly connected with the triangular block 210. The moving block 24 will drive the connecting rod 29 to move together through the hinge block 28, so that the distance between the three groups of connecting rods 29 is shortened, and the reverse rotation will increase the distance between the connecting rods 29 to adapt to the processing of gears of different sizes. There are three groups of arc-shaped sliders 23, and the three groups of arc-shaped sliders 23 are penetrated by arc-shaped rods 212, and the arc-shaped springs 213 are fixedly connected between every two groups of arc-shaped sliders 23. The top surface of the fixed block 21 is penetrated and slidably connected with a support rod 214, and the top surface of the support rod 214 is fixedly connected with a placement plate 215. When the gear is pressed downward, the placement plate 215 will be pressed downward and the support rod 214 will be pushed downward, and the spring 217 will be compressed. When the gear is inserted into the bottom of the triangular clamping block 210, not only will the torsion spring 211 clamp the inner edge of the gear by pulling back the connecting rod 29, but the compressed spring 217 will also push the placement plate 215 to lift the gear to be processed, so that the bottom of the gear is clamped with the placement plate 215, and the triangular clamping block 210 is clamped with the top of the gear, so that the gear is positioned more tightly. The surface of the placement plate 215 is provided with a limiting groove 216, and the connecting rod 29 penetrates the limiting groove 216 and is slidably connected. The bottom surface of the placement plate 215 is fixedly connected with a spring 217, and the end of the spring 217 away from the placement plate 215 is fixedly connected to the top surface of the fixed block 21. The threaded rod 26 penetrates the moving block 24, and the threaded rod 26 is threadedly connected with the moving block 24.

The connecting rod 29 also penetrates the arc-shaped slider 23, and a torsion spring 211 is fixedly connected between the arc-shaped slider 23 and the connecting rod 29. After the connecting rod 29 rotates, the torsion spring 211 is tightened. When the top of the gear exceeds the bottom of the triangular clamping block 210, the tightened torsion spring 211 will pull back the connecting rod 29 to drive the triangular clamping block 210 to clamp the top of the gear, so that the connecting rod 29 clamps the inner edge of the gear.

[0024] Based on the above embodiment, when processing the gear, the inner edge of the gear is aligned with the triangular clamp block 210 and pressed downward, so that the inner edge of the gear contacts the triangular clamp block 210 and forces the connecting rod 29 and the hinge block 28 to rotate. After the connecting rod 29 rotates, the torsion spring 211 is tightened. When the top of the gear exceeds the bottom of the triangular clamp block 210, the tightened torsion spring 211 pulls back the connecting rod 29 to drive the triangular clamp block 210 to clamp the top of the gear, so that the connecting rod 29 clamps the inner edge of the gear, and when the gear is pressed downward, The placement plate 215 is pressed downward and the support rod 214 is pushed downward, and the spring 217 is compressed. When the gear is inserted into the bottom of the triangular clamping block 210, not only the torsion spring 211 clamps the inner edge of the gear by pulling back the connecting rod 29, but the compressed spring 217 also pushes the placement plate 215 to lift the gear to be processed, so that the bottom of the gear is clamped with the placement plate 215, and the triangular clamping block 210 is clamped with the top of the gear, so that the gear is positioned more tightly and the gear teeth can be prevented from being worn during gear processing.

[0025] If encountering gears of different sizes, the knob 27 can be turned to make the knob 27 drive the threaded rod 26 to rotate, and the moving block 24 is located on the inner side of the slide groove 25, so that the slide groove 25 limits the moving block 24, so that the threaded rod 26 rotates and drives the moving block 24 to slide in the slide groove 25, and the moving block 24 will drive the connecting rod 29 to move together through the hinge block 28, so that the distance between the three groups of connecting rods 29 is shortened, and the reverse rotation will increase the distance between the connecting rods 29 to adapt to the processing of gears of different sizes. The adjustment is convenient and simple, and the adaptability is strong.
