Description

Technical Field

[0001] The utility model relates to the technical field of gear processing, in particular to a fixing fixture for gear processing. Background Art

[0002] Gears can transfer power from one shaft to another and increase or decrease torque as needed. By combining gears of different sizes and shapes, different transmission ratios can be achieved, thereby changing the output speed and torque. Gear sets can change the direction of rotation. For example, by using a worm and worm wheel combination, the direction of rotation can be changed from horizontal to vertical, or vice versa. Gears need to be processed to finally get the required specifications or sizes. Before processing, the gears need to be fixed to avoid gear offset or shaking during processing, resulting in unqualified results. Fixing the gears requires the use of a fixing fixture for gear processing.

[0003] The fixture uses its clamping components, such as jaws, fixture chuck, etc., to firmly fix the gear workpiece on the fixture to ensure that it will not move or twist during the processing. The fixture is usually equipped with locating pins or locating holes to ensure that the gear workpiece is in the correct position. These locating components can cooperate with the corresponding features on the workpiece to ensure the accurate positioning of the workpiece during the processing. The fixture may be equipped with adjusting bolts or clamping force control devices to adjust the strength of the fixture clamping components to adapt to gear workpieces of different sizes and shapes.

[0004] Traditional fixtures are usually designed for workpieces of specific sizes and shapes, so the fixture may need to be adjusted or replaced when the workpiece is changed, which will increase the mold change time and processing costs. Since traditional fixtures usually require manual adjustment and fixation of the workpiece, the processing preparation time is relatively long, which may reduce processing efficiency. The positioning and fixing mechanism of traditional fixtures may be affected by mechanical wear or looseness, resulting in reduced processing accuracy. Since traditional fixtures require workers to operate and adjust the workpiece on the fixture, there may be a risk of clamping or injury. Utility Model Content

[0005] In order to make up for the above shortcomings, the utility model provides a fixing fixture for gear processing, which aims to improve the problem that the fixture can only clamp workpieces of specific sizes and shapes, and needs to be manually adjusted and fixed. Since traditional fixtures require workers to operate and adjust the workpiece on the fixture, there may be a risk of clamping or injury.

[0006] The cam is provided with a toothed plate, and the toothed plate ...

[0007] Furthermore, the fixing assembly includes a moving block, and the moving block is slidably connected inside the machine body.

[0008] Furthermore, a connecting column is slidably connected inside the moving block.

[0009] Furthermore, a second rack is provided on the side wall of the connecting column, and a fixed shaft is fixedly connected inside the moving block.

[0010] Furthermore, the side wall of the fixed shaft is rotatably connected with a second gear, the second gear is meshed with the second rack, and the second rack is slidably connected inside the moving block.

[0011] Furthermore, a motor is fixedly connected inside the moving block, a rotating disk is fixedly connected to an output end of the motor, and connecting shafts are fixedly connected to two side walls of the gear.

[0012] Furthermore, one end of the connecting shaft is fixedly connected to a worm wheel, and the side wall of the turntable is fixedly connected to a worm.

[0013] Furthermore, the worm is meshed with the worm wheel.

[0014] The utility model has the following beneficial effects:

[0015] 1. In the utility model, the push rod is firstly outputted by the cylinder, thereby driving the fixed rod, and then driving the slider to slide, thereby driving the connecting plate to slide, and then driving the fixed block to slide. In this process, due to the mutual cooperation of the slider, the fixed block and the connecting plate, the clamping plate is driven to slide, and then the rack 1 is driven to move. Since the gear 1 and each rack 1 are meshed with each other, the rack 1 on the other side is driven to move through the gear 1, and then the clamping plate on the other side is driven to slide, thereby achieving the effect of fixing the workpiece, thereby avoiding direct contact between the workers and the clamp, and reducing the risk of injury by the clamp.

[0016] 2. In the utility model, the motor outputs the turntable to drive the worm to rotate. Since the worm and the worm wheel are meshed with each other, the connecting shaft drives the gear 2 to rotate. In this process, the gear 2 is meshed with the rack 2. As the gear 2 rotates, the rack 2 also slides, thereby driving the moving block to slide on the connecting column, thereby completing the adjustment of the distance between the processing device and the workpiece, so that the processing device can adapt to gears of different specifications, thereby improving work efficiency and providing a guarantee for the quality of the gears.

[0025] Specifically, the push rod 3 is output through the cylinder 2, and since the fixed platform 23 is provided with a slide groove 5, the fixed rod 4 can slide in the slide groove 5. The fixed column 7 is connected to the fixed plate 12, which causes the slider 6 to move on the fixed column 7. The slider 6 is connected to the fixed block 8 through the connecting plate 13, so when the slider 6 moves, the fixed block 8 will also move accordingly. The slider 6 is connected to the rack 9, and the rack 9 is meshed with the gear 10. In this process, since the fixed block 8 slides on another fixed column 7, there is another slider 6 on the fixed column 7. The slider 6 is connected to another fixed column 7 through another connecting plate 13, thereby driving the other rack 9 to move. Eventually, the splints 11 on both sides move toward the middle.

[0026] Reference Figure 4The fixed component includes a moving block 22, which is slidably connected to the inside of the body 1. A connecting column 21 is slidably connected to the inside of the moving block 22. A rack 20 is provided on the side wall of the connecting column 21. A fixed shaft 19 is fixedly connected to the inside of the moving block 22. A gear 2 18 is rotatably connected to the side wall of the fixed shaft 19. The gear 2 18 meshes with the rack 20. The rack 20 is slidably connected to the inside of the moving block 22. A motor 14 is fixedly connected to the inside of the moving block 22. A turntable 24 is fixedly connected to the output end of the motor 14. A connecting shaft 17 is fixedly connected to the side wall of the gear 2 18. A worm gear 16 is fixedly connected to one end of the connecting shaft 17. A worm 15 is fixedly connected to the side wall of the turntable 24. The worm 15 meshes with the worm wheel 16.

[0027] Specifically, the motor 14 outputs power to the turntable 24, so that the worm 15 rotates, and the worm 15 meshes with the worm wheel 16, so that the worm wheel 16 rotates following the rotation of the worm 15. In this process, the worm wheel 16 is connected to the gear 2 18 through the connecting shaft 17, and the gear 2 18 is connected to the fixed shaft 19. Therefore, as the worm wheel 16 rotates, the gear 2 18 also rotates accordingly. The gear 2 18 meshes with the rack 20, and the rack 20 is fixed on the connecting column 21, and the connecting column 21 is connected to the body 1. Therefore, the rotation of the gear 2 18 drives the moving block 22 to slide along the connecting column 21 to realize the control of the distance of the workpiece, thereby achieving the control of the distance of the workpiece.

[0028] Working principle: The push rod 3 is output through the cylinder 2. Since the fixed platform 23 is provided with a slide groove 5, the fixed rod 4 is pulled to slide in the slide groove 5. Since the fixed column 7 is connected to the fixed plate 12, the slider 6 is driven to slide on the fixed column 7. Since the slider 6 is connected to the fixed block 8 through the connecting plate 13, as the slider 6 slides, the fixed block 8 also slides. Since the slider 6 is connected to the rack 9, the rack 9 is meshed with the gear 10. In this process, since the fixed block 8 slides on another fixed column 7, there is another slider 6 on the fixed column 7, and the slider 6 is connected to another fixed column 7 through another connecting plate 13, the rack 9 drives the other rack 9 to move, which leads to the two The clamping plate 11 on the side moves toward the middle, thereby completing the fixation of the workpiece, and the turntable 24 is output through the motor 14, thereby driving the worm 15 to rotate. Since the worm 15 and the worm wheel 16 are meshed with each other, the worm wheel 16 rotates as the worm 15 rotates. In this process, since the worm wheel 16 is fixed to the gear 2 18 through the connecting shaft 17, and the gear 2 18 is connected to the fixed shaft 19, as the worm wheel 16 rotates, the gear 2 18 also rotates. In view of the fact that the gear 2 18 and the rack 2 20 are meshed with each other, and the rack 20 is on the connecting column 21, and the connecting column 21 is fixed to the body 1, the gear 2 18 drives the moving block 22 to slide along the connecting column 21, thereby achieving the control of the workpiece distance.
