Description

Technical Field

[0001] The utility model relates to a bearing assembly tool, in particular to a steel ball feeding die. Background Art

[0002] The steel ball feeding mold is a device specially designed for handling and dispersing the fallen steel balls. The design and structure of this mold can effectively disperse the fallen steel balls for subsequent processing and use. The design and use of this mold can greatly improve production efficiency, save labor costs, and ensure the quality and consistency of steel balls.

[0003] At present, one cycle of steel ball feeding is that the steel ball feeding mold receives a number of steel balls from the upper level, then sends the steel balls into the gap between the inner and outer rings of the matching bearing, and then disperses the steel balls through the pressing rod. In this process, the crescent part of the bottom of the steel ball feeding mold will be in continuous contact with the steel balls, so the crescent part of the steel ball feeding mold is easy to break and damage, and the structural function of the steel ball feeding mold directly affects the quality of the steel balls, causing the entire steel ball feeding mold to be scrapped.

[0004] In view of this, the Chinese utility model patent publication (publication number CN 217452893 U, hereinafter referred to as document 1) discloses a steel ball feeding mold, which includes a steel ball feeding component and a crescent base, the steel ball feeding component has a steel ball channel and a blowing channel, the top of the crescent base is detachably connected to the steel ball feeding component, the bottom of the crescent base has a crescent part, the crescent base has a feeding channel, the bottom of the steel ball channel is connected to the feeding channel, so that the steel balls pass through the steel ball channel and the feeding channel in turn, the top of the blowing channel is used to communicate with the blowing device, and the bottom of the blowing channel is connected to the steel ball channel and / or the feeding channel, so that air passes through the blowing channel and the feeding channel in turn and is used to disperse the steel balls. If the crescent part is broken, only the crescent base needs to be replaced.

[0005] However, after the feed inlet channel on the crescent base of Document 1 is assembled with the steel ball groove, the steel balls are randomly scattered on the inner wall of the feed inlet channel. Since the steel balls collide with the inner wall at different angles, it is easy to cause the collision points and damage points of the inner wall of the feed inlet channel to appear concentrated at certain specific angles or areas, so that the crescent base needs to be replaced frequently. Utility Model Content

[0006] The purpose of the utility model is to provide a steel ball feeding mold, which can have better durability than the existing technology.

[0020] The present invention will be described more clearly and completely below by way of embodiments in conjunction with the accompanying drawings.

[0021] Figure 1 This is a schematic structural diagram of a steel ball feeding mold according to an embodiment of the utility model. Figure 2 , is a schematic diagram of the three-dimensional structure of the crescent portion of an embodiment of the utility model, Figure 3 Schematic diagram of the structure of the crescent portion of one embodiment of the utility model when viewed from above and from the side. Figure 4 This is a three-dimensional structural diagram of a crescent fixing seat according to an embodiment of the utility model. Figure 5 , which is a schematic diagram of the structure of the crescent fixing seat in a top view and a side view of an embodiment of the utility model. Figure 1-5 As shown, the steel ball feeding mold 1 involved in this embodiment is connected to a steel ball feeding component with a feeding channel (not shown in the figure), comprising: a crescent portion 2, the crescent portion 2 having a cylindrical feeding port 25 with an opening 24 on the side, and a disc-shaped base 20, a crescent fixing seat 3, having a recessed portion 31 that can be assembled with the base 20 and a through hole 32 for the feeding port 25 to pass through, the axial direction of the feeding port 25 is perpendicular to the base 20, and is formed on one side end face of the base 20, when the base 20 is assembled with the crescent fixing seat 3, one end of the feeding port 25 passes through the through hole 32, and the other end is connected to the feeding channel, and the crescent fixing seat 3 has a side with a recessed portion 31 fixed to the steel ball feeding component. The specific structure of the steel ball feeding component with a feeding channel can refer to the document 1 of the prior art, which will not be repeated here.

[0022] The cylindrical inlet 25 of the crescent 2 is matched with the through hole 32 of the crescent fixing seat 3. This design allows the inlet 25 to pass through the through hole 32 when necessary, so that the entire crescent 2 can be easily removed and replaced from the crescent fixing seat 3 after wear or damage. Since the crescent 2 is the part that directly contacts the steel ball and is most easily damaged, this easy-to-replace design can greatly reduce the maintenance cost and downtime of the entire mold. In short, compared with the prior art, only the crescent needs to be replaced instead of the crescent fixing seat.

[0023] In addition, since the feed port 25 has a cylindrical shape and is provided with an opening 24, it helps to more evenly distribute the impact force of the steel balls in the feed channel, thereby reducing concentrated wear in a specific area. The axial direction of the feed port 25 is perpendicular to the base 20 and is formed on one side end surface of the base 20. This vertical structural design helps to better guide and control the steel balls before entering the feed channel, thereby improving the uniformity of the steel ball dispersion.

[0024] Furthermore, the crescent portion 2 is formed of an elastic thermoplastic material. The elastic properties of the material can reduce the impact of hard collisions, thereby reducing the wear of the steel ball on the crescent portion. Thermoplastic materials have certain toughness and wear resistance, can absorb and disperse impact force, reduce damage and wear, and thus improve the durability of the crescent portion.

[0025] Furthermore, the crescent fixing seat 3 is formed in a disc shape and has screw countersunk holes 33 and 34 for adjusting the rotation angle of the crescent fixing seat 3 when fixing. By adjusting the rotation angle of the crescent fixing seat, the feeding direction and distribution of the steel balls can be optimized, and the uniformity of the dispersion of the steel balls can be further improved. This design also allows the user to adjust the contact surface according to the actual wear condition and evenly use different areas of the crescent part, thereby extending its service life.

[0026] Furthermore, the feed port 25 has a wing 251 extending from the edge of the opening 24 to the inside of the opening 24 at one end close to the base 20. Accordingly, the through hole on the crescent fixing seat 3 is formed into a corresponding shape to accommodate the passage of the wing 251. Here, extending to the inside of the opening 24 can also be understood as extending toward each other in the width direction of the opening 24. In this embodiment, the through hole is formed in the shape of a gourd hole, and the wing can pass through the protruding part of the gourd hole.

[0027] Furthermore, the feed port 25 has a protrusion 252 extending from the edge of the opening 24 and in the extending direction of the opening 24 at one end away from the base 20. Here, the extending direction of the opening 24 can also be understood as the length direction of the opening 24.

[0028] The design of the wing 251 and the protrusion 252 helps to better guide and control the flow direction of the steel balls, reducing the random scattering of the steel balls and the collision in the feeding channel. Such structural improvements not only help to reduce local wear, but also enhance the orientation of the steel balls when entering the channel, thereby improving the uniformity of the dispersion of the steel balls.

[0029] The wing 251 and the protrusion 252 ensure accurate positioning and fixation of the feed port through the design of the through hole (gourd hole) with matching shape, which helps to stabilize the structure of the mold and maintain the consistency of the dispersion of the steel balls.

[0030] Furthermore, the crescent portion 2 is fixed to the crescent fixing seat 3 by a plurality of bolts. Figure 3and Figure 5 As shown, the crescent portion 2 has screw holes 22 and 23, which correspond to screw holes 35 and screw holes 36 on the crescent fixing seat 3 for fixing. Using bolts to fix the crescent portion provides a stable and reliable connection method, which is convenient for maintenance and quick replacement when necessary. This fixing method allows the crescent portion to remain stable when subjected to repeated impacts, reducing additional wear caused by position movement.

[0031] The above contents are only preferred embodiments of the present invention and cannot limit the scope of implementation of the present invention. That is, all equivalent changes and modifications made within the scope defined in the claims of the present invention should still fall within the protection scope of the present invention.
