Description

Technical Field

[0001] This utility model relates to the field of flexible bearing tooling technology, specifically flexible bearing assembly tooling. Background Technology

[0002] A flexible bearing is a type of bearing with special elastic deformation capabilities. When subjected to load, it can generate a certain degree of deformation through its own elastic structure to adapt to special working conditions. For example, in a harmonic reducer, a flexible bearing works in conjunction with a wave generator to achieve a large transmission ratio and compact structure by utilizing elastic deformation. It is like a flexible joint, cleverly transmitting power and ensuring transmission accuracy.

[0003] When manually assembling flexible bearings, workers typically place the inner ring and balls between the outer ring. During assembly, the outer ring is usually initially secured to facilitate the placement of the inner ring and balls. However, some assembly fixtures are currently unable to clamp bearing outer rings of different sizes, which affects the assembly process. In addition, during ball assembly, balls may accidentally fall out, as some fixtures cannot prevent them from falling outside the work area, which also affects the assembly process. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a flexible bearing assembly fixture, including a work plate, a side column fixed to one side of the work plate surface, a pushing mechanism provided on the surface of the side column, and action blocks provided on both sides of the work plate surface. One action block is fixed to the surface of the work plate, and the other action block slides on the surface of the work plate via the pushing mechanism. A placement groove is formed on the surface of each action block, and a clamping assembly is provided on the surface of the placement groove. The fixture also includes:

[0006] A tilting mechanism is provided on the surface of the work plate.

[0008] Preferably, the thread helix angle of the threaded rod is less than the equivalent friction angle, which gives the threaded rod self-locking properties.

[0009] Preferably, limit rods are fixed on both sides of the surface of the action block on one side, and the other end of the limit rod slides in the inner cavity of the side column.

[0010] Preferably, the clamping assembly includes a connecting frame, bolts, and a clamping block. The connecting frame slides on the surface of the placement groove and is connected to the actuating block by bolts. The clamping block is fixed to one side of the surface of the connecting frame.

The working plate is kept horizontal by the placement block and the placement plate on the other side. The barrier frame is fixed to the surface of the working plate. The through groove is opened on one side of the barrier frame. The collection shell is movably disposed on one side of the surface of the placement plate.

[0019] 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.

[0020] Please see Figure 1-4 As shown, the flexible bearing assembly fixture includes a work plate 1, a side post 2 fixed to one side of the surface of the work plate 1, a pushing mechanism 3 provided on the surface of the side post 2, and action blocks 5 provided on both sides of the surface of the work plate 1. One action block 5 is fixed to the surface of the work plate 1, and the other action block 5 slides on the surface of the work plate 1 through the pushing mechanism 3. A placement groove 6 is formed on the surface of the action block 5, and a clamping assembly 7 is provided on the surface of the placement groove 6. The fixture also includes:

[0021] Inclination mechanism 8 is provided on the surface of work plate 1.

[0022] When assembling flexible bearings, workers can flexibly select different clamping components 7 according to the size of the bearing to be assembled. With the cooperation of the propulsion mechanism 3, the outer ring of the bearing is clamped by the clamping components 7 on both sides to stabilize it, thus achieving the purpose of clamping the outer ring of bearings of different sizes. In addition, the tilting mechanism 8 can also block falling balls and collect them after the work is completed, improving the practicality of the device and the convenience of the assembly work.

[0023] The propulsion mechanism 3 includes a meshing cylinder 31 that rotates on one side of the surface of the side column 2. A threaded rod 32 is meshed in the inner cavity of the meshing cylinder 31. The other end of the threaded rod 32 is fixed to the surface of the action block 5. A force-bearing block 33 is fixed on the surface of the meshing cylinder 31. In this embodiment, through the arrangement of the meshing cylinder 31, the threaded rod 32 and the force-bearing block 33, the meshing cylinder 31 rotates under the action of the force-bearing block 33, which in turn causes the threaded rod 32 meshing in the inner cavity of the meshing cylinder 31 to rotate, thereby causing the threaded rod 32 to move, which in turn drives the action block 5 on one side to move.

[0024] The thread helix angle of the threaded rod 32 is less than the equivalent friction angle, which makes the threaded rod 32 self-locking. In this embodiment, this setting can prevent the threaded rod 32 from moving on its own after it has moved.

[0025] Limiting rods 4 are fixed on both sides of the surface of the action block 5. The other end of the limiting rod 4 slides in the inner cavity of the side column 2. In this embodiment, the limiting rod 4 provides a limit for the movement of the action block 5, thereby improving the stability of the action block 5 when it moves.

[0026] The clamping assembly 7 includes a connecting frame 71, a bolt 72, and a clamping block 73. The connecting frame 71 slides on the surface of the placement groove 6 and is connected to the action block 5 by the bolt 72. The clamping block 73 is fixed to one side of the surface of the connecting frame 71. In this embodiment, by setting the connecting frame 71, the bolt 72, and the clamping block 73, the specified connecting frame 71 and clamping block 73 can be set on the surface of the action block 5 by the bolt 72, thereby achieving the purpose of replacing the clamping block 73. This is suitable for flexible bearings of different sizes.

[0027] The tilting mechanism 8 includes placement blocks 81, placement plate 82, barrier frame 83, through groove 84, and collection shell 85. Several placement blocks 81 are fixed to the surface of the placement plate 82. The working plate 1 rotates on the surface of one side of the placement blocks 81 via a pivot. The working plate 1 is kept horizontal by the other side of the placement blocks 81 and placement plate 82. The barrier frame 83 is fixed to the surface of the working plate 1. The through groove 84 is formed on one side of the barrier frame 83. The collection shell 85 is movably disposed on one side of the surface of the placement plate 82. In this embodiment, the tilting mechanism 8 uses placement blocks 81 and placement plate 82 to tilt the plate. 2. The arrangement of the barrier frame 83, the through groove 84, and the collection shell 85 allows the working plate 1 to be placed in the working area under the action of the placement plate 82. Under the action of the placement block 81 on one side, a support point is provided for the rotation of the working plate 1. Under the action of the placement block 81 on the other side, the working plate 1 can be horizontally supported. Under the action of the barrier frame 83, the spilled bearing balls can be blocked. Then, after the working plate 1 is tilted, the balls can fall into the collection shell 85 under the action of the through groove 84, thus achieving the purpose of collecting the spilled balls.

[0028] Working principle: When using this device, the operator can flexibly select the corresponding clamping component 7 according to the size of the outer ring of the bearing to be assembled. Then, under the action of the connecting frame 71 and the bolt 72, the corresponding clamping block 73 is installed on the surface of the two side action blocks 5. Then, the outer ring of the bearing can be placed between the two side clamping blocks 73. Then, using the force block 33, under the action of the force block 33, the meshing cylinder 31 and the threaded rod 32 are meshed. Then, under the drive of the threaded rod 32, the one side action block 5 drives the clamping component 7 to clamp the outer ring of the bearing. Then, the operator can place the ball and the inner ring of the bearing between the outer ring, thereby achieving the purpose of assembling the flexible bearing. During assembly, if some bearing balls accidentally fall off, the blocking frame 83 will prevent the balls from rolling out of the working range. After the work is finished and the flexible bearing is removed, the operator can tilt the working plate 1, and the balls can fall into the collection shell 85 through the through groove 84, making it convenient for the operator to collect the fallen balls.
