Description

Technical Field

[0001] This utility model relates to the field of positioner technology, specifically to a planetary gear reducer assembled positioner. Background Technology

[0002] Planetary gear reducers are a widely used industrial product that can reduce the speed of a motor while increasing its output torque. They are used as components in industries such as lifting, excavation, transportation, and construction.

[0003] An internal gear ring (A) is tightly coupled to the gearbox housing. At the center of the ring gear is a sun gear (B) driven by external power. Between the two is a planetary gear set (C) consisting of three gears equally distributed on the tray. This planetary gear set floats between the output shaft, the internal gear ring, and the sun gear. When the input power drives the sun gear, the planetary reducer can drive the planetary gears to rotate and revolve around the center along the trajectory of the internal gear ring. The rotation of the planetary gears drives the output shaft connected to the tray to output power.

[0004] Planetary gear reducers need to be rotated during assembly, usually by manual labor with the help of a crane. However, the rotation process causes the planetary gear reducer to become unstable due to the change in the center of gravity, posing a significant safety hazard. Utility Model Content

The technical problem it solves is that during the planetary reducer assembly process, the tilting motion poses a significant safety hazard and results in low efficiency.

[0018] Furthermore, the arm body of clamping arm B has a groove for placing the pressure arm.

[0019] Furthermore, the dual-slide screw module B is connected to the frame of the lifting mechanism in a fixed structure.

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the utility model will now be described in further detail with reference to the accompanying drawings and the following embodiments, so that the public can better understand the implementation method of this utility model. The specific implementation scheme of this utility model is as follows:

[0031] A planetary reducer assembly positioner includes a lifting mechanism 2, a tilting mechanism 3 mounted on the lifting mechanism 2, and a clamping mechanism mounted on the tilting mechanism 3. This structure is existing technology, as exemplified by the mechanism within a lifting and tilting positioner as described in Chinese Utility Model Patent Application No. 200920259512.4. The clamping mechanism is characterized by a double-slide screw module A4, which is fixedly connected to the tilting mechanism 3. Clamping arms A5 are fixedly mounted on the two slides of the double-slide screw module A4, and the clamping arms A5 are vertically connected to... Hydraulic cylinder 6 has a pressure arm 7 fixedly mounted on its output shaft. The planetary reducer is radially clamped by clamping arm A5, and then the edge of the planetary reducer is pressed against clamping arm A5 by pressure arm 7 for axial fixation, ensuring stability during the flipping process and improving safety. A double slide screw module B8 is mounted at the lower part of clamping arm A5. Clamping arms B9 are fixedly mounted on the two slides of the double slide screw module B8, and a support block 11 is fixedly mounted on the upper inner side of clamping arm B9 to support the planetary reducer and prevent damage to the gear parts of the planetary reducer due to pressure.

[0032] The turntable 12 is fixedly connected to the double slide table lead screw module B8 via the rotary drive 13, and the turntable 12 is located between the two clamping arms B9, which facilitates the rotation to install the surrounding parts, reduces the obstruction of the positioner, and improves the assembly efficiency.

[0033] It should be noted that both the double-slide screw module A4 and the double-slide screw module B8 include a support. The support has two slides slidably mounted on it. Inside the support, there are positive and negative screws that are rotatably mounted. The positive and negative threads of the positive and negative screws are respectively threaded to one of the slides to drive the two slides to move relative to or towards each other. The support is equipped with a geared motor or rotary motor that drives the positive and negative screws to rotate. The geared motor or rotary motor is connected to the middle of the positive and negative screws via a commutator and a key.

[0034] It should be noted that the clamping arm A5 and the pressure arm 7 are equipped with guide posts 14 to ensure stable operation.

[0035] Specifically, both clamping arms A5 and B9 include arm bodies that are fixedly connected to the corresponding slides. A retaining arm 15 is fixedly arranged on the inner side of the arm body, and the retaining arm 15 can fit against the outer peripheral surface of the planetary reducer. The support block 11 is arranged in an L-shape, and the vertical side of the support block 11 limits the edge surface, while the horizontal side of the support block 11 supports the lower end surface of the edge.

[0036] To reduce space occupation and better conform to the shape characteristics of the planetary reducer, the arm body of the clamping arm B9 is provided with a groove 10 for placing the pressure arm 7.

[0037] The dual-slide table lead screw module B8 is connected to the frame 1 of the lifting mechanism 2 in a fixed structure, ensuring that the positioner is an integral structure and reducing installation and adjustment time.

[0038] The working principle and process of this utility model are as follows:

[0039] First, the planetary gear reducer gear housing is located at the bottom, such as... Figure 5 As shown, the support block 11 is used to support and limit the outer edge.

[0040] When flipping is required, the double slide screw module A4 is activated to move the clamping arm A5 inward until the clamping arm 15 on the clamping arm A5 clamps the planetary reducer. Then, the hydraulic cylinder 6 is activated, and the output shaft of the hydraulic cylinder 6 drives the pressure arm to press the edge against the lower end face of the clamping arm 15 of the clamping arm A5. Then, the lifting mechanism 2 drives the parts and products on the double slide screw module A4 to move upward and stop after reaching the predetermined position. Then, the flipping mechanism 3 drives the double slide screw module A4 and the product to flip. After flipping 180 degrees, the lifting mechanism 2 moves it down until the planetary reducer is placed on the turntable 12 for assembly.
