Description

Technical Field

[0001] This utility model relates to the field of planetary carrier technology, and in particular to a precision forming fixture for planetary carrier components. Background Technology

[0002] The planetary carrier is the core component of a planetary gear transmission system. It supports and connects the planetary gears, enabling them to revolve around the sun gear and transmit power. It is a structurally complex part, and a suitable planetary carrier structure should be lightweight, rigid, and easy to manufacture and assemble. Common structural forms include integral double-sided plate type, separate double-sided plate type, and single-sided plate type. The structural form of the planetary carrier largely depends on its intended use, the manufacturing method, and the assembly conditions of the planetary gear reducer. A reasonable planetary carrier structure should have small overall dimensions, be lightweight, ensure even load distribution among the planetary gears, and possess excellent machining and assembly processes, enabling the planetary gear transmission to have high load-bearing capacity and low vibration and noise.

[0003] The existing technical solutions mentioned above have the following drawbacks: the existing planetary carriers lack a stable clamping and fixing structure during processing, which cannot improve processing accuracy and affects product quality. Utility Model Content

[0004] The purpose of this invention is to provide a precision forming fixture for planetary carrier assemblies.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A precision forming fixture for planetary carrier components includes a base, a placement platform and a mounting base fixedly connected to the outer side of the base, a first positioning element and a second positioning element fixedly connected to the outer side of the placement platform, a first motor fixedly connected to the outer side of the mounting base, a lead screw installed inside the mounting base, a moving block sleeved on the outer side of the lead screw, a bracket fixedly connected to the outer side of the moving block, and a clamping block fixedly connected to the outer side of the bracket.

[0007] By adopting the above technical solution, a placement platform is added inside the base, and a positioning component is added outside the placement platform to position the bottom of the planetary carrier body. Then, a clamping part is added to the outside of the planetary carrier body. The first motor drives the lead screw to drive the moving block and the clamping block to move, so that the clamping block contacts the outside of the planetary carrier body. Multiple sets are pressed at the same time, which can clamp and fix the outside of the planetary carrier.

[0008] Furthermore, a support base is fixedly connected to the outer side of the base, a rotating arm is installed inside the support base, a clamping block is fixedly connected to the outer side of the rotating arm, a limit pin is fixedly connected inside the clamping block, and a rotating shaft is fixedly connected inside the rotating arm.

[0009] By adopting the above technical solution, a rotating arm that can rotate is added to the outside, which can drive the limit pin and the clamping block to rotate, insert the limit pin into the hole at the upper end of the planetary carrier body, limit the upper part, improve the overall stability and the accuracy during processing.

[0010] Furthermore, a first bevel gear is fixedly connected to the outer side of the rotating shaft, a limit plate is fixedly connected to the outer side of the support base, a second motor is fixedly connected to the outer side of the support base, a second bevel gear is fixedly connected to the output end of the second motor, and a planetary carrier body is installed on the outer side of the placement platform.

[0011] By adopting the above technical solution, the second motor drives two sets of bevel gears to mesh, which can drive the rotating shaft and rotating arm to rotate, making it convenient to control and adjust.

[0012] Furthermore, the mounting base, the first motor, the lead screw, the moving block, the bracket, and the clamping block are distributed in a ring at equal intervals. The output end of the first motor is fixedly connected to one end of the lead screw on the outside. The other end of the lead screw on the outside is rotatably connected to the mounting base through a bearing. The lead screw and the moving block are threadedly connected. The clamping block adopts an arc-shaped structure.

[0013] By adopting the above technical solution and adding multiple sets of clamping structures, the outer side can be clamped after positioning to ensure the stability of the overall structure.

[0014] Furthermore, the support base, rotating arm, clamping block, limiting pin, rotating shaft, first bevel gear, limiting plate, second motor, and second bevel gear are distributed in multiple rings at equal intervals. The limiting plate adopts an inclined structure. The first bevel gear and the second bevel gear are meshed and connected. The rotating arm and the support base are rotatably connected by the rotating shaft.

[0015] By adopting the above technical solution, and by adding multiple sets of upper-end limiting structures in conjunction with the bottom positioning components, the overall positioning accuracy can be improved, facilitating processing operations.

[0016] In summary, the beneficial technical effects of this utility model are as follows:

[0017] The system employs a placement platform, positioning components, a motor, a lead screw, a rotating arm, and a bevel gear. By adding positioning components and limiting pins and clamping blocks on the outside of the rotating arm, the planetary carrier body can be positioned first. By simultaneously performing positioning treatment at both the upper and lower ends, the positioning accuracy is improved. Then, a clamping structure is added to the outside to clamp the outside of the planetary carrier body, ensuring the stability of the overall structure and resulting in improved machining accuracy and workpiece stability.

The planetary carrier body 20 is installed on the outside of the placement platform 2. The placement platform 2 is added inside the base 1. A positioning component is added to the outside of the placement platform 2 to position the bottom of the planetary carrier body 20. Then, a part for clamping the planetary carrier body 20 is added to the outside. The first motor 6 drives the lead screw 7 to drive the moving block 8 and the clamping block 10 to move, so that the clamping block 10 contacts the outside of the planetary carrier body 20. Multiple sets are clamped at the same time to clamp and fix the outside of the planetary carrier. A rotating arm 12 that can rotate is added to the outside, which can drive the limit pin 14 and the clamping block 13 to rotate. The limit pin 14 is inserted into the hole at the upper end of the planetary carrier body 20 to limit the upper part, improve the overall stability and the accuracy during processing.

[0025] like Figure 1-4 As shown, mounting base 5, first motor 6, lead screw 7, moving block 8, bracket 9, and clamping block 10 are arranged in a ring at equal intervals. The output end of the first motor 6 is fixedly connected to one end of the lead screw 7 on the outside.

The limiting plate 17 adopts an inclined structure. The first bevel gear 16 and the second bevel gear 19 are meshed together. The rotating arm 12 and the support base 11 are rotatably connected through the rotating shaft 15.

[0026] The implementation principle of this embodiment is as follows: The planetary carrier body 20 is placed on the placement platform 2, and the bottom hole is aligned with the positioning component. Then, the second motor 18 is started, driving two sets of bevel gears to mesh, causing the rotating arm 12 to start rotating. The limiting pin 14 is inserted into the hole at the upper end of the planetary carrier body 20. At the same time, the clamping block 13 on the outside of the limiting pin 14 contacts the upper surface of the planetary carrier body 20 to achieve the clamping effect. Then, the first motor 6 is started, and the first motor 6 drives the lead screw 7 to drive the clamping block 10 to move, bringing the clamping block 10 into contact with the outside of the planetary carrier body 20. Multiple sets move simultaneously to achieve the clamping effect, improving the stability of the planetary carrier body 20 after installation and improving the processing accuracy.
