Description

Technical Field

[0001] The utility model relates to the technical field of bearing production, in particular to a ball pushing device for installing a ball bearing. Background Art

[0002] Ball bearings are a type of rolling bearings. The ball is installed between the inner and outer steel rings and can withstand large loads. They are also called ball bearings.

[0003] When installing ball bearings, a fixed number of balls need to be clamped between the outer steel ring and the inner steel ring and installed using a retaining frame. During the ball installation process, due to the small space and the inability to effectively fix the number of balls installed at a time, workers often encounter the need to install a single ball in a certain small space. It is very inconvenient to grab a single ball and install it. Therefore, a pushing device is needed to facilitate the placement of a single ball in the small space between the steel rings and ensure that the ball is pushed out smoothly and will not be taken out again by the pushing device.

DETAILED DESCRIPTION

[0022] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more specific definition of the protection scope of the present invention. The directional terms mentioned in the present invention, such as "up", "down", "front", "back", "left", "right", "top", "bottom", etc., are only for reference to the directions of the attached drawings. Therefore, the directional terms used are used to illustrate and understand the present invention, rather than to limit the present invention.

[0023] like Figure 1-3 The ball pushing device for installing a ball bearing shown in the figure comprises an operating tube 1, a feeding tube 2, a feeding tube 3, a stripping device 4, a control component 5, a spring 6, a pressure ring 7, a positioning magnetic ring 8 and a limit cover 9. The feeding tube 2 is fixedly arranged on the outside of the operating tube 1, the feeding tube 3 is sleeved on one end of the feeding tube 2, the stripping device 4 is clamped on the outside of the bottom of the operating tube 1, the control component 5 is arranged inside the operating tube 1, the pressure ring 7 is fixedly arranged on the inside of the operating tube 1, the positioning magnetic ring 8 and the limit cover 9 are clamped on the inside of the bottom of the operating tube 1, the control component 5 comprises a telescopic rod 51, a pressing head 52, a pressing plate 53, a ball head 54 and an adsorption magnetic block 55. The telescopic rod 51 is clamped on the inside of the top of the operating tube 1, the pressing head 52 is fixedly arranged on the top of the telescopic rod 51, the pressing plate 53 is fixedly arranged on the surface of the telescopic rod 51, the spring 6 is sleeved on the outside of the telescopic rod 51, the ball head 54 is fixedly arranged at the bottom end of the telescopic rod 51, and the adsorption magnetic block 55 is fixedly arranged on the inside of the bottom of the ball head 54.

[0024] Specifically, the stripping device 4 includes a clamping ring 41 and a claw 42, the clamping ring 41 is sleeved on the bottom outer side of the operating tube 1, the claw 42 is fixedly arranged at the bottom of the clamping ring 41, and the bottom of the claw 42 is inclined toward the center. The positioning magnetic ring 8 is fixedly arranged on the bottom outer side of the connecting end of the feeding tube 2 and the operating tube 1, and the limiting cover 9 is located at the bottom outer side of the positioning magnetic ring 8. A stabilizing ring sleeved on the outside of the telescopic rod 51 is fixed on the inside of the operating tube 1. The spring 6 is arranged between the pressure plate 53 and the pressure ring 7. An arc groove is arranged at the bottom of the ball head 54. The bottom of the adsorption magnetic block 55 and the arc groove surface of the bottom of the ball head 54 are located on the same arc surface. The ball head 54 is located on the top outer side of the connecting end of the feeding tube 2 and the operating tube 1. The limiting cover 9 has a funnel-shaped structure. The limiting cover 9 is made of rubber material. The inner side of the top of the limiting cover 9 and the inner side of the positioning magnetic ring 8 are located on the same arc surface as the inner wall of the operating tube 1.

[0025] In this embodiment, first, the inner diameter of the feeding tube 3 is slightly larger than the diameter of the ball. The feeding tube 3 is filled with the balls to be installed. After the balls enter the feeding tube 2, they fall into the operating tube 1. At this time, the balls are adsorbed and positioned by the positioning magnetic ring 8, thereby blocking the end of the feeding tube 2 to ensure that only a single ball is filled in the operating tube 1. The limiting cover 9 effectively provides an insurance function to prevent the positioning magnetic ring 8 from being unable to effectively adsorb the balls and causing the balls to fall directly. The limiting cover 9 has a funnel-shaped structure to effectively ensure the limiting support effect.

[0026] The ball is then pushed back into the operating tube 1 by the push rod 51 and the push plate 53 is pressed against the spring 6 to press the spring 6 into contraction. The ball head 54 is moved downward to push the adsorbed single ball downward to leave the positioning magnetic ring 8 and pass through the limiting cover 9. Since the limiting cover 9 is made of rubber and has good elasticity, it will not excessively hinder the movement of the ball. At this time, the surface of the ball fits the bottom of the ball head 54, and the adsorption magnetic block 55 effectively adsorbs the ball. Subsequently, the ball passes through the claw 42, and the claw 42 is stretched open by the ball. After the ball is pushed to the ideal area, the pressing head 52 is released. Under the action of the spring 6, the ball head 54 automatically rises. At this time, the ball will be blocked by the claw 42 and cannot enter the operating tube 1 again, thereby realizing the ball installation work. After the ball head 54 is reset, the single ball falls to the positioning magnetic ring 8 again, and a new ball installation work can be started.

[0027] It should be noted that the parts not covered in the present invention are the same as the prior art or can be implemented by the prior art; the various drives in the present invention can be implemented by corresponding power structures such as cylinders, oil cylinders, electric cylinders, motors, etc. in combination with connecting rods, guide rods, etc., and are not limited to the description in the specification and the structures in the drawings.

[0028] In the description of the embodiments of the present utility model, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "set", "provided with", etc. should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0029] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
