Description

Technical Field

[0001] This utility model relates to the field of speed reducer manufacturing technology, and in particular to a speed reducer seal assembly fixture. Background Technology

[0002] In the production of speed reducers, the assembly precision of the seals directly affects the sealing performance and service life of the equipment. Existing assembly devices use clamps connected to a fan to create negative pressure to pull the rubber rings during assembly. However, this method easily attracts dust and other foreign objects, causing airflow blockage and uneven suction on the rubber rings. This leads to deformation of the rubber rings, ultimately causing them to fall off, misaligned with the rotating ring, and impacting subsequent processing efficiency.

[0003] A patent document with authorization announcement number CN218311893U discloses a sealing component assembly device that can improve the feeding accuracy. The device includes a conveyor belt, a material trough and a straight guide rail on the side of the conveyor belt, a lifting cylinder at the bottom of the material trough, a lifting plate connected to the top of the lifting cylinder, a moving cylinder connected to the straight guide rail, a deflection motor and several inner clamping plates connected to the moving cylinder, and several outer clamping plates hinged to the side of the moving cylinder. A deflection torsion spring is provided at the hinge of the moving cylinder. The outer clamping plates correspond to the inner clamping plates, and the bottom end of the outer clamping plates is bent to form a material-picking hook. The deflection motor is connected to a deflection ring, which is sleeved on the outside of the outer clamping plates. The inner side of the deflection ring has an arc-shaped block. This achieves a U-shaped surrounding structure formed by the material-picking hooks at the lower ends of the inner and outer clamping plates, which lifts the rubber ring and avoids uneven force on different parts of the rubber ring, thus preventing deformation. This ensures that the rubber ring can be aligned and fall onto the moving ring, guaranteeing smooth subsequent processing.

[0004] However, the aforementioned comparative documents only pre-position the seal using simple positioning pins, without considering the installation deviation of the reducer housing. This makes the seal prone to eccentricity and twisting after assembly, leading to seal failure and affecting the production quality of the reducer. Therefore, we provide a reducer seal assembly fixture. Utility Model Content

This fixture enables the gearbox housing to be positioned and fixed during the assembly of the seal, preventing it from shifting. This ensures that the seal is accurately installed on the gearbox and improves the production quality of the gearbox.

[0026] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1

[0028] The prior art document addresses the issue of difficulty in stabilizing the gearbox housing, which can easily lead to seal misalignment and ultimately seal failure. This embodiment provides a gearbox seal assembly fixture, please refer to [reference needed]. Figure 1 - Figure 5 This device can position and fix the reducer housing during the assembly of the seals, preventing misalignment and ensuring precise installation of the seals on the reducer, thus improving the production quality of the reducer. The reducer seal assembly fixture includes a positioning sleeve 2 mounted on the top of a conveyor table 1, a clamping mechanism 3 for fixing seals of different sizes on the top of the conveyor table 1, and an adjusting and positioning mechanism 4 for stabilizing the reducer housing on the conveyor table 1. The clamping mechanism 3 can fix sealing rings of different sizes, improving the stability of the assembly, while the adjusting and positioning mechanism 4 can position and fix reducers of different sizes, thereby improving the applicability of the device and increasing the assembly efficiency of the seals.

[0029] The comparison document relies solely on simple positioning pins for pre-positioning of the seals, neglecting the installation deviation of the reducer housing. This leads to the seals being prone to eccentricity and twisting after assembly, causing seal failure and affecting production quality. To solve the above problems, the adjusting positioning mechanism 4 includes fixed frames 41 installed on both sides of the conveyor table 1. Sliding blocks 42 are slidably connected inside the fixed frames 41. A buffer spring 43 connected to the bottom of the sliding blocks 42 is connected to the bottom of the fixed frames 41. Horizontal seats 44 are installed inside the two sets of sliding blocks 42. Electric push rods 45 are installed at both ends inside the horizontal seats 44. A mounting rod 46 penetrating the side of the horizontal seat 44 is installed at the output end of the electric push rod 45. A positioning element 47 is movably installed inside the mounting rod 46. Several sets of elastic blocks are installed inside the positioning element 47. The elastic blocks can increase the friction with the reducer housing, further improving the fixing stability of the reducer. The positioning element 47 is also equipped with a series of elastic blocks. The fixing bolt is fixed to the mounting rod 46, which facilitates the disassembly and assembly of the positioning component 47 and makes it easy to replace it. A dual-axis motor 48 is installed at the bottom of the conveyor table 1. The output ends of the dual-axis motor 48 are connected to the rotating rods 49. Supports 410 that are rotatably connected to the rotating rods 49 are installed on both sides of the bottom of the conveyor table 1. The supports 410 are symmetrically distributed at the bottom of the conveyor table 1, which makes the rotating rods 49 rotate more stably. A pressing plate 411 is installed at the other end of the rotating rods 49. The pressing plate 411 and the pressure rod 412 are both made of rubber, which plays a double protection role. The outside of the slider 42 is equipped with a pressure rod 412 corresponding to the position of the pressing plate 411. The reducer is placed inside the positioning sleeve 2. The operation of two sets of electric push rods 45 causes the two sets of positioning parts 47 installed to position and fix the reducer housing, thereby improving the assembly stability of the seal. The operation of the dual-shaft motor 48 causes the two sets of rotating rods 49 to rotate, thereby driving the extrusion plate 411 to contact the pressure rod 412. This allows the height of the positioning parts 47 to be adjusted within a certain range, improving the positioning and fixing efficiency of the reducer.

[0030] Example 2

[0031] Based on Example 1, such as Figure 1 - Figure 5 As shown, based on the existing comparative documents, it is not easy to position and stabilize the reducer housing, which can easily cause the seal to shift and lead to seal failure. However, traditional assembly devices mostly use fixed-size positioning structures, which can only accommodate a single specification of seal. When the outer diameter, thickness or inner diameter of the seal changes, the corresponding structure needs to be replaced simultaneously, which reduces the assembly efficiency of the seal. Therefore, this device is also equipped with a structure to fix seals of different sizes.

[0032] Traditional assembly devices have fixed positioning structure dimensions, only suitable for a single specification of seal. When the size changes, the structure needs to be replaced, resulting in low assembly efficiency. To solve this problem, the clamping mechanism 3 includes a fixed frame 31 mounted on the top of the conveyor table 1. A vision sensor is installed on the upper inner side of the fixed frame 31 to facilitate more precise placement of the seal on the reducer. A drive motor 32 is mounted on the top of the fixed frame 31. A connecting plate 33 is mounted on the output end of the drive motor 32. An electrically controlled lifting rod 34 is mounted on one side of the top of the connecting plate 33. A circular frame 35 is mounted on the bottom of the electrically controlled lifting rod 34. A partition 36 is installed inside the circular frame 35. A circular cover 37 is mounted on the bottom of the partition 36. An asynchronous motor 38 is mounted inside the partition 36. The asynchronous motor 38 is distributed between the circular frame 35 and the partition 36. The circular frame 35 provides protection for the asynchronous motor 38. A square base 39 is installed at the output end of the 38. Bent rods 310 are rotatably connected inside the four corners of the square base 39. A clamping claw 311 is installed at the other end of the bent rod 310 and is slidably connected to the round cover 37. The clamping claws 311 are symmetrically distributed in pairs at the bottom of the round cover 37, so that seals of different sizes can be fixed and the fixing efficiency can be improved. Multiple sets of sliding grooves 312 adapted to the clamping claws 311 are opened on the outer side of the round cover 37. A vacuum cleaner 313 is installed on the other side of the top of the connecting plate 33. A vacuum cleaner hood 314 is installed at the bottom of the vacuum cleaner 313. The vacuum cleaner hood 314 is on the same vertical plane as the positioning sleeve 2, so that the dust can be vacuumed at the place where the seal is placed, thereby improving the production quality of the reducer. Before the seal is assembled, the vacuum cleaner 313 and the vacuum hood 314 are rotated to the top of the reducer by the operation of the drive motor 32, which can remove dust. After the dust is removed, the clamping structure is rotated to the top of the reducer. The square seat 39 is rotated by the operation of the asynchronous motor 38. Under the limit of the bent rod 310 and the slide groove 312, the four sets of clamping claws 311 fix the seal, which further improves the assembly efficiency of the seal.
