Description

Technical Field

[0001] This utility model relates to the field of bearing assembly machinery technology, specifically to an assembly mechanism for a linear ball bearing. Background Technology

[0002] A linear ball bearing is a mechanical component used to support and guide the movement of moving parts in a linear direction. It typically consists of an outer ring, an inner ring, rolling elements (usually steel balls), and a cage. The main function of a linear ball bearing is to reduce friction, making movement smoother, while also being able to withstand certain radial and axial loads. Linear ball bearings are widely used in various mechanical equipment, especially in applications requiring precise linear motion, such as CNC machine tools, automated equipment, measuring instruments, and printing equipment.

[0003] Current linear bearing assembly is done manually using simple auxiliary tools. During assembly, due to the small diameter of the balls (less than 2mm), it is difficult to control the balls during manual installation. This leads to problems such as misplaced balls, incorrect ball placement, and slow assembly speed, reducing production efficiency and compromising product quality. Furthermore, prolonged installation can damage the eyesight of installers, increasing the factory's labor costs.

[0004] In existing technologies, such as the patent with publication number CN104373468A, a linear bearing assembly device solves the assembly problem of the linear bearing balls and the linear bearing cage. During assembly, it is only necessary to install the cage, press the handle to draw in the balls, and install the outer ring to complete the entire linear bearing assembly process. However, in the above patent, the shape of the head positioning part matches the shape of the groove or hole of the linear bearing cage to be assembled, and there are gaps at both ends of the bearing inner shell and the cage. This will weaken the suction force in the cage groove. When the gap is larger than the inner diameter of the ball, it will also cause the ball to be adsorbed inside the gap, requiring manual replacement, causing damage to the cage and cumbersome procedures.

[0005] To address the aforementioned issues, it is necessary to provide an assembly mechanism for linear ball bearings that is easy to operate and has better adaptability. Utility Model Content

[0006] The purpose of this invention is to provide an assembly mechanism for linear ball bearings, overcoming the aforementioned defects in the prior art.

[0007] The technical solution to achieve the purpose of this utility model is: an assembly mechanism for a linear ball bearing, including a ball suction device, an air suction device, and a ball pool. The ball suction device includes a housing and a fixing member sleeved on the housing. An air passage is provided inside the housing, and the air passage of the housing is connected to the air suction device through a hose. A ball suction part is provided at the head of the housing, and at least one suction hole is provided on the side wall of the ball suction part. The ball suction part of the housing can be inserted into the cage. The fixing member is adapted to clamp the cage outside the ball suction part. An annular groove communicating with the suction hole is provided on the ball suction part at a position corresponding to the ball filling hole of the cage.

[0008] In a preferred embodiment, the annular groove is disposed at the end of the housing, and the bottom of the ball pool is provided with at least one flat surface. The fixing member and the bottom of the ball pool respectively seal the gaps at both ends of the retainer and the annular groove.

[0009] In a preferred embodiment, the fixing member is slidably disposed on the outside of the housing.

[0032] (Example)

[0033] See Figure 1 An assembly mechanism for a linear ball bearing includes a ball suction device 1, an air suction device 2, and a ball pool 3.

[0034] The ball suction device 1 includes a housing 11 and a fixing member 12 that is slidably sleeved on the housing 11. The housing 11 has a hollow structure, a connecting pipe port is provided at the tail end of the housing 11, and a suction hole 13 is provided on the side wall of the head of the housing 11.

[0035] The suction device 2 consists of a vortex air pump (not shown in the figure) and a suction pipe 21 connected to the vortex air pump. The suction pipe 21 housing is also provided with four suction pipe holes 22. Each suction pipe hole 22 can be connected to the connection port of a suction ball device 1 through a flexible hose.

[0036] The bottom of the ball pool 3 is a flat plate, which contains balls that are compatible with the cage 100. One end of the cage 100 is placed flat at the bottom of the ball pool 3.

[0037] The ball-suction part of the housing 11 can be inserted into the retainer 100; the fixing member 12 is adapted to clamp the retainer 100 on the outside of the ball-suction part, and the ball-suction part is provided with an annular groove 14 corresponding to the ball-filling hole of the retainer 100, which communicates with the suction hole 13. When the head of the housing 11 is inserted into the retainer 100, the flat plate at the bottom of the ball pool 3 and the fixing member 12 respectively seal both ends of the retainer 100. Through the cooperation of the ball pool and the fixing member, both ends of the retainer are sealed; a gap is left between the head of the housing 11 and the inside of the retainer 100, and the suction force of the suction hole 13 on the housing 11 located inside the retainer will be distributed to the ball-filling hole of the retainer through the gap. The balls in the ball pool are sucked into the retainer by the suction force, completing the ball filling. This design can be adapted to the ball filling of retainers of various specifications without the need to specifically open suction holes for the position of the retainer holes.

[0038] Furthermore, the fastener 12 is made of elastic rubber and is slidably disposed on the outside of the housing 11. The fastener 12 has good sealing performance, facilitates the fixing of the cage, has low cost, and is easy to maintain and replace. The sliding arrangement also makes it more convenient for operators to operate.

[0039] Furthermore, a handle 11-1 is provided at the tail of the housing 11, and the handle 11-1 is provided with a plurality of protrusions arranged in sequence; a stop 11-2 is provided between the handle 11-1 and the fixing member 12.

[0040] During operation, place the cage 100 at the bottom of the ball pool 3, insert the ball-absorbing part of the fixing member 11 into the cage 100, fix the fixing member 12 to the upper end of the cage 100, seal the upper end of the cage 100, turn on the suction device 2 to complete the ball loading. Then turn off the suction device 2 and install the cage 100 with the loaded balls into the outer ring of the bearing.

[0041] This embodiment utilizes a ball suction device to automatically load balls into the cage by designing the bottom of the ball pool and a sliding fixing component, effectively improving work efficiency and loading quality. The handheld part features raised protrusions to increase friction, facilitating operator handling and improving efficiency. By incorporating a suction pipe, multiple ball suction devices can be connected simultaneously, enabling one device to handle four simultaneously, further increasing production efficiency. Increasing the power of the vortex air pump can further increase the number of suction pipe holes, allowing connection of more suction devices and further improving work efficiency.
