Description

Technical Field

[0001] This utility model relates to the field of machining fixtures, specifically a planetary gear machining fixture. Background Technology

[0002] Planetary gears are the core components of planetary gear transmission systems. They are precision mechanical parts and are widely used in transmission devices such as gearboxes, reducers, and differentials. As the core component of precision transmission parts (such as planetary gearboxes), the machining accuracy of planetary gears directly affects the stability and lifespan of the transmission system. Fixtures are required for positioning during machining.

[0003] Existing planetary gear machining fixtures require inserting planetary gears into the fixture. To prevent the planetary gears from detaching from the fixture, structures such as cylinders and pressure plates are needed to press down on the planetary gears. However, different sizes of planetary gears require different pressure plate lengths. To avoid the pressure plate being too short to press down on the planetary gears, or too long to press down on the planetary gears and cause machining obstacles, the pressure plate size needs to be changed frequently. This results in poor applicability of the fixture. Therefore, a new planetary gear machining fixture is proposed. Utility Model Content

The pressing component is used to press down on the positioning components. The upper pressing component includes a second cylinder, which is fixedly connected to the base. A top plate is fixedly connected to the output end of the second cylinder. An upper pressing plate is slidably installed on one end of the top plate. The upper pressing plate is used to press down on the upper end of the planetary gear.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] A planetary gear machining fixture, such as Figures 1-5 As shown, the system includes a base 1, with multiple sets of positioning components installed on the upper end of the base 1. A pressing component and an upper pressing component are provided around the positioning components on the upper end of the base 1. The pressing and lowering components are located on both sides of the positioning components. Each positioning component is equipped with a pressing component and an upper pressing component. The pressing component is used to press down on the positioning components. The upper pressing component includes a second cylinder 8, which is fixedly connected to the base 1. A top plate 9 is fixedly connected to the output end of the second cylinder 8. An upper pressing plate 11 is slidably installed on one end of the top plate 9. The upper pressing plate 11 is used to press down on the upper end of the planetary gear 7.

[0024] By inserting the planetary gear 7 into the positioning component, which is then installed on the base 1, the positioning component and the base 1 bracket are detachable. The lower pressing component presses down on the positioning component to fix it on the base 1, and the upper pressing component presses down on the planetary gear 7 to fix it on the positioning component. The upper pressing plate 11 slides on one end of the top plate 9. The length of the upper pressing plate 11 protruding from the top plate 9 is adjusted so that the length of the upper pressing plate 11 can be adapted to the size of the planetary gear 7. This eliminates the need for frequent changes in the pressing plate size and improves the applicability of the fixture.

[0025] The top plate 9 has a groove 10 with one end open. One end of the upper pressure plate 11 is slidably installed in the groove 10. A locking component for fixing the upper pressure plate 11 is slidably installed on the top plate 9.

[0026] One end of the upper pressure plate 11 slides in the slide groove 10. Adjust the length of the upper pressure plate 11 protruding from the top plate 9, and then fix the upper pressure plate 11 by the locking component.

[0027] The locking assembly includes a fixing rod 15, which is vertically slidably mounted on the top plate 9. The fixing rod 15 has a positioning plate 13 and a connecting plate 16 fixedly connected to its two ends respectively. The positioning plate 13 is located in the slide groove 10. The upper end of the upper pressure plate 11 has a toothed groove 12. The lower end of the positioning plate 13 has a toothed tooth 14 fixedly connected to it. The toothed tooth 14 engages with the toothed groove 12.

[0028] Pulling up the connecting plate 16, the positioning plate 13 is disengaged from the upper pressure plate 11 via the fixing rod 15, causing the teeth 14 to disengage from the tooth groove 12. The upper pressure plate 11 is not locked and can slide. Pressing down the connecting plate 16, the teeth 14 engage with the tooth groove 12, and the upper pressure plate 11 is locked and positioned.

[0029] A spring 17 is fitted on the side wall of the fixing rod 15. One end of the spring 17 is fixedly connected to the connecting plate 16, and the other end is fixedly connected to the upper end of the top plate 9. The spring 17 is in an extended state.

[0030] Spring 17 is always in an extended state and has a tendency to contract. Spring 17 pulls connecting plate 16 so that positioning plate 13 is always in close contact with upper pressure plate 11, so that positioning plate 13 firmly positions upper pressure plate 11.

[0031] The positioning component includes a positioning seat 5, a positioning groove 2 is provided on the upper end of the base 1, a positioning block 6 is fixedly connected to the lower end of the positioning seat 5, the positioning block 6 is inserted into the positioning groove 2, a fixed seat 18 is fixedly connected to the upper end of the positioning seat 5, and a planetary gear 7 is inserted into the fixed seat 18.

[0032] The positioning block 6 at the bottom of the positioning seat 5 is inserted into the positioning groove 2 of the base 1. The positioning groove 2 and the positioning block 6 are polygonal, and the positioning seat 5 cannot be rotated.

[0033] The pressing assembly includes a cylinder 3, which is fixed to the base 1. The output end of the cylinder 3 is rotatably connected to a pressing plate 4, which is used to press down the positioning seat 5.

[0034] After the positioning seat 5 is installed, cylinder 3 retracts, causing the lower pressure plate 4 to descend. The lower pressure plate 4 presses tightly against the positioning seat 5 to prevent the positioning seat 5 from detaching from the base 1.

[0035] The working principle of the planetary gear 7 machining fixture provided by this utility model is as follows:

[0036] The positioning seat 5 is inserted and installed on the base 1, and the planetary gear 7 is installed on the fixed seat 18. The output ends of cylinder 3 and cylinder 8 retract, and the upper pressure plate 11 and the lower pressure plate 4 press down on the upper end of the planetary gear 7 and the positioning seat 5 respectively. The connecting plate 16 is pulled, and the upper pressure plate 11 slides on one end of the top plate 9. The length of the upper pressure plate 11 protruding from the top plate 9 is adjusted so that the length of the upper pressure plate 11 can be adapted to the size of the planetary gear 7. Then the connecting plate 16 is released, and the positioning plate 13 fixes the upper pressure plate 11. The pressure plate size does not need to be changed frequently, and the applicability of the fixture is improved.
