[0027] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0028] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention 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 invention, and not all embodiments.

[0029] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate for the embodiments of the utility model described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or device that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or devices.

[0030] In existing technologies, grinding is usually performed by fixing individual bearings. This is not only inefficient, but also cumbersome as it requires sequential installation and disassembly of each bearing. Furthermore, it can lead to inconsistent grinding levels among bearings in the same batch, affecting the overall grinding effect. Therefore, a grinding machine that can grind the end faces of multiple bearings simultaneously is needed.

[0031] In view of this, the present invention aims to provide a precision bearing machining grinding machine, in which, as Figure 1 and Figure 2 As shown, the bearing processing grinding machine includes a support base 1 and a grinding mechanism 2. The grinding mechanism 2 is mounted on the support base 1 to perform grinding work on the bearing. In this embodiment, a positioning mechanism 3 is provided on the support base 1. The positioning mechanism 3 is used to place multiple bearings and can fix multiple bearings.

[0032] The positioning mechanism 3 comprises a positioning box 31, a cover plate 32, and a clamping mechanism. The positioning box 31 is located at the bottom of the grinding mechanism 2, allowing the grinding mechanism 2 to grind the bearings on the positioning box 31. The cover plate 32 is detachably mounted on the upper end of the positioning box 31 using screws. The positioning box 31 contains multiple positioning slots 311, with the bottom of the bearing placed within each slot. In this embodiment, twenty positioning slots 311 are provided, enabling the grinding mechanism 2 to grind twenty bearings simultaneously. The twenty positioning slots 311 are evenly arranged as follows: Figure 5 As shown; Figure 4 As shown, the cover plate 32 has a positioning hole 321 corresponding to the positioning groove 311 at the upper end of the positioning groove 311, so that when the bearing is placed, the bottom of the bearing can directly enter the positioning groove 311. It should be noted that after the bearing is placed in the positioning groove 311, the upper end face of the bearing is located at the upper end of the cover plate 32, so that the grinding mechanism 2 can perform grinding work on the upper end face of the bearing. The positioning groove 311 limits the bottom of the bearing, and the positioning hole 321 limits the middle of the bearing to prevent the bearing from tilting when placed.

[0033] Regarding the clamping mechanism, it is used to clamp the bearing inside the positioning box 31 to prevent the bearing from shaking during grinding. The clamping mechanism is located inside the positioning box 31 and includes a first lead screw 33, a second lead screw 34, and a clamping motor 35. The first lead screw 33 and the second lead screw 34 are located on opposite sides inside the positioning box 31, with both ends of the first lead screw 33 and the second lead screw 34 mounted inside the positioning box 31 via rotating shafts. The threads on the first lead screw 33 and the second lead screw 34 have opposite directions of rotation. The clamping motor 35 is mounted inside the positioning box 31, and its output shaft is connected to the first lead screw 33 to drive its rotation. A pulley 37 is fixed to both the first lead screw 33 and the second lead screw 34, and the two pulleys 37 are connected by a belt drive to ensure that when the clamping motor 35 drives the first lead screw 33 to rotate, it can simultaneously drive the second lead screw 34 to rotate in the same direction. Figure 5 and Figure 6As shown, clamping plates 36 are provided on both the first lead screw 33 and the second lead screw 34. Multiple clamping plates 36 are provided. Since the positioning grooves 311 are arranged in five rows in this embodiment, five clamping plates 36 are provided on both the first lead screw 33 and the second lead screw 34 to clamp the bearings on the five rows of positioning grooves 311. The clamping plates 36 on the first lead screw 33 and the second lead screw 34 are staggered within the positioning box 31. The clamping plates 36 are used to clamp the bearings within the positioning box 31 from both sides. The clamping plates 36 on the first lead screw 33 and the second lead screw 34 are centrally symmetrically arranged. One end of each clamping plate 36 is threaded onto the first lead screw 33 and the second lead screw 34, and the other end is slidably connected to the inner wall of the positioning box 31. A slide rail is provided on the inner wall of the positioning box 31. A slider is provided, and one end of the clamping plate 36 extends to connect with the slider to ensure the stability of the movement of the clamping plate 36. During clamping, the clamping motor 35 is started to drive the first lead screw 33 to rotate. The multiple clamping plates 36 on the first lead screw 33 move to contact and clamp the bearing. At the same time, the pulley 37 drives the second lead screw 34 to rotate in the same direction. Since the threads on the first lead screw 33 and the second lead screw 34 turn in opposite directions, the clamping plates 36 on the second lead screw 34 move synchronously and in the opposite direction to the movement of the clamping plates 36 on the first lead screw 33. The clamping plates 36 on the first lead screw 33 and the clamping plates 36 on the second lead screw 34 move closer to each other to clamp and fix the bearing. After the grinding work is completed, the clamping motor 35 drives the first lead screw 33 to grip in the opposite direction, and the clamping plates 36 release their clamping of the bearing, allowing the bearing to be easily removed.

[0034] This utility model, through the arrangement of positioning box 31, cover plate 32 and clamping mechanism, can clamp and position multiple bearings simultaneously, so that grinding mechanism 2 can simultaneously grind the ends of multiple bearings fixed on positioning box 31, greatly improving grinding efficiency, ensuring that the grinding degree of multiple bearings on positioning box 31 is consistent, reducing grinding differences between bearings, and making it convenient and quick to clamp and fix multiple bearings. The bearings will not tilt when directly placed into positioning hole 321, and the positioning is accurate and convenient for unloading. It can also be adapted to clamping bearings of different sizes.

[0035] To improve the stability of bearing clamping, such as Figure 6 As shown, an arc-shaped clamping groove 361 is provided on the side of the clamping plate 36 near the positioning groove 311. The arc-shaped clamping groove 361 matches the arc shape of the side of the bearing to clamp the bearing, which can prevent the clamping plate 36 from sliding between the bearing during clamping and improve the stability of clamping.

[0036] In order to collect the debris generated during grinding; such as Figure 7As shown, an adsorption groove 312 is provided at the bottom of the positioning box 31. The adsorption groove 312 is located at the bottom of the positioning groove 311. A fan 38 is installed inside the adsorption groove 312. A filter screen is provided at the input end of the fan 38. The output end of the fan 38 is connected to the outside. The adsorption groove 312 is connected to the bottom of each positioning groove 311, so that negative pressure can be generated in each positioning groove 311 for adsorption. A support 39 is provided inside the positioning groove 311 to support the bearing. The support 39 is set as a mesh structure to allow gas and debris to enter the adsorption groove 312. In this embodiment, in order to accommodate bearings of different sizes, the positioning groove 311 is set as a larger groove. Therefore, after the bearing is placed, an adsorption channel will be formed around the bearing. During grinding, the debris is carried by the airflow through the adsorption channel and enters the adsorption groove 312 for collection.

[0037] To facilitate the loading and unloading of bearings; such as Figure 3 As shown, a moving mechanism 4 for driving the positioning box 31 is provided on the support base 1. The moving mechanism 4 includes a moving motor 41, a moving lead screw 42, a positioning rail 43, and a sliding seat 44. A mounting cavity is provided on the support base 1. The moving motor 41 is installed in the mounting cavity of the support base 1. The moving lead screw 42 is mounted on the support base 1 via bearings. The output shaft of the moving motor 41 is connected to one end of the moving lead screw 42, driving the moving lead screw 42 to rotate in both forward and reverse directions. The positioning rail 43 is fixed to the upper end face of the support base 1. The positioning rail 43 is located on the moving... The upper end of the moving lead screw 42; the sliding seat 44 is fixed to the bottom of the positioning box 31, and a limiting hole 45 is opened on the sliding seat 44. The positioning track 43 passes through the limiting hole 45, so that the sliding seat 44 and the positioning box 31 move along the direction of the positioning track 43. One end of the positioning track 43 extends to the bottom of the grinding mechanism 2, and the other end extends to the loading and unloading area for bearing loading and unloading. The bottom of the sliding seat 44 is threaded onto the moving lead screw 42, so that the sliding seat 44 and the positioning box 31 move on the positioning track 43 when the moving lead screw 42 rotates.

[0038] In this embodiment, the grinding mechanism 2 includes a support frame 21, a sliding frame 22, a lifting cylinder 23, a grinding motor 24, and a grinding disc 25. The support frame 21 is fixedly installed on the support base 1. The sliding frame 22 is installed on the support frame 21. The sliding frame 22 is vertically arranged and has a track vertically arranged on it. A slider is arranged on the track. The lifting cylinder 23 is installed on the support frame to drive the slider to rise and fall. The slider is fixedly connected to the mounting box. The grinding motor 24 is installed in the mounting box. The grinding disc 25 is connected to the bottom output shaft of the grinding motor 24. The cylinder drives the grinding motor 24 and the grinding disc 25 to rise and fall. The grinding motor 24 drives the grinding disc 25 to rotate to perform the grinding work on the bearing.

[0039] To improve the flexibility of the grinding mechanism 2, such as Figure 1 and Figure 2As shown, the support frame 21 is configured as a fixed part 211 and a rotating part 212. The rotating part 212 is located at the upper end of the fixed part 211, and the fixed part 211 is installed at the upper end of the support base 1. The sliding frame 22 is set on the rotating part 212 and moves with the rotating part 212. The fixed part 211 is provided with a driving component (not shown in the figure) to drive the rotating part 212 to rotate. The driving component to drive the rotating part 212 is a relatively mature existing mechanical mechanism, which will not be described in detail in this embodiment. For example, a motor, a drive gear and an internal gear ring can be set to cooperate to drive the rotation. By setting the grinding mechanism 2 as a horizontally rotatable mechanism, the position of the grinding disc 25 can be adjusted and the moving grinding operation can be performed.

[0040] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
