Abstract
Description
Technical Field
[0001] The utility model relates to a demagnetization matching device for a bearing. Background Art
[0002] During the manufacturing and processing of bearings, bearing materials will be magnetized due to various mechanical operations such as cutting, grinding, polishing, etc. The presence of this magnetization has a variety of potential negative effects on the performance and application of bearings, especially in high-precision and high-demand industrial applications.
[0003] During the operation of the bearing, if the bearing has residual magnetism, it will attract magnetic impurities such as iron particles. These impurities may be entrained in the lubricating oil, forming abrasive wear on the bearing surface, accelerating the wear and damage of the bearing. Bearings used in motors and other electrical equipment, if they are magnetic, may cause current to pass through the bearing path, causing so-called current erosion. This erosion will form small pits on the bearing surface, eventually impairing the operating performance of the bearing.
[0004] In addition, in some precision equipment and instruments, such as medical equipment and precision measuring tools, the magnetism of the bearings will interfere with the normal operation of the equipment and affect the measurement and operation accuracy of the equipment.
[0005] By demagnetizing the bearing, the overall reliability and service life of the bearing can be improved. Bearings that are not demagnetized are more likely to cause problems during operation, thus ending their service life prematurely.
[0006] In many traditional devices, it is difficult to accurately control the speed at which the bearing passes through the demagnetization device. Too fast a speed may result in the bearing not being completely demagnetized, while too slow a speed will reduce production efficiency. Due to the lack of an effective positioning system, the bearing may have position deviations when passing through the demagnetization device, resulting in uneven demagnetization effects, especially the treatment of key parts such as the inner ring groove diameter may not be ideal. Utility Model Content
[0007] The purpose of the utility model is to provide a demagnetization matching device for a bearing, which can better control the passage of the bearing to achieve effective demagnetization.
[0008] The utility model solves the above technical problems through the following technical solutions:
[0009] A demagnetizing and matching device for a bearing comprises: a base, the top of the base having a mounting surface inclined relative to a horizontal plane, a demagnetizing device, the demagnetizing device being mounted on the mounting surface, the demagnetizing device having a channel for demagnetizing the bearing, and a matching guide rail, the matching guide rail passing through the channel and being inclined relative to the horizontal plane, the inclination direction of the matching guide rail and the channel being the same as the inclination direction of the mounting surface.
[0010] Preferably, the inclination angle of the mounting surface is adjustable.
[0011] Preferably, a stop block is provided at the lower end of the fixed guide rail, and the stop block can be displaced in the fixed guide rail to block / release the bearing, and the demagnetization device has a sensor for detecting whether there is a bearing in the channel.
[0012] Preferably, when the residence time of the bearing in the channel is less than a set value, the stop block is displaced to block the bearing.
[0013] Preferably, when the bearing passes through the passage, the stop block is displaced to stop the bearing.
[0014] Preferably, the material stopper is connected to a pneumatic cylinder, and the pneumatic cylinder is controlled by a solenoid valve to drive the material stopper to extend into the fixed guide rail, or to retract so that the material stopper is separated from the fixed guide rail.
[0015] Preferably, the base is connected with a V-shaped bracket, and two supporting points of the V-shaped bracket are fixed to the bottom of the base. The inclination angle of the mounting surface can be adjusted by changing the mounting angle between the V-shaped bracket and the external device.
[0016] In summary, it is essential to achieve efficient and uniform demagnetization that the bearings maintain a uniform and constant speed when passing through the channel, while ensuring that each bearing passes through the demagnetization zone along the same path. This avoids poor demagnetization caused by position deviation or improper speed. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The present invention will be described more clearly and completely below by way of embodiments in conjunction with the accompanying drawings.
[0020] Figure 1 This is a structural schematic diagram of a demagnetization matching device for a bearing according to an embodiment of the utility model. Figure 2 FIG. 1 is a schematic diagram of the structure of a demagnetization matching device for a bearing during installation according to an embodiment of the utility model. Figure 1 , 2As shown, the demagnetization and matching device for the bearing involved in this embodiment includes: a base 7, the top of the base 7 has a mounting surface 71 inclined relative to the horizontal plane, a demagnetization device 6, the demagnetization device 6 is installed on the mounting surface 71, the demagnetization device 6 has a channel 61 for demagnetizing the bearing, and a matching guide rail 5, the matching guide rail 5 passes through the channel 61 and is inclined relative to the horizontal plane, and the inclination direction of the matching guide rail 5 and the channel 61 is the same as the inclination direction of the mounting surface 71.
[0021] The top of the base 7 has an inclined mounting surface 71, on which the demagnetization device 6 is installed. The inclined mounting helps to utilize gravity to assist the movement of the bearing on the fixed guide rail 5, ensuring that the bearing passes through the demagnetization channel 61 at a constant and appropriate speed. This natural inclined guiding method is more controllable than the traditional horizontal passing method, and can effectively prevent the problem of too fast or too slow speed. The fixed guide rail 5 passes through the channel 61 of the demagnetization device and is also inclined. This design ensures that the position of the bearing is accurate and stable when passing through the demagnetization device. The inclination of the guide rail is consistent with the inclination direction of the demagnetization device, which further enhances the stability of the passage and the uniformity of demagnetization, especially for key parts such as the inner ring groove diameter of the bearing. The bearing can maintain a uniform and constant speed when passing through the channel 61, while ensuring that each bearing passes through the demagnetization area along the same path, which is crucial to achieving efficient and uniform demagnetization. Poor demagnetization caused by position deviation or improper speed is avoided.
[0022] Furthermore, the inclination angle of the mounting surface 71 is adjustable.
[0023] Furthermore, a stop block 4 is provided at the lower end of the fixed guide rail 5 , and the stop block 4 can be displaced in the fixed guide rail 5 to block / release the bearing, and the demagnetization device 6 has a sensor for detecting whether there is a bearing in the channel 61 .
[0024] Further, when the bearing passes through the channel 61, the stopper block 4 is displaced to stop the bearing.
[0025] In other embodiments, when the residence time of the bearing in the channel 61 is less than a set value, the stopper 4 is displaced to block the bearing. When the sliding time of the bearing in the fixed guide rail 5 is not enough for demagnetization (for example, the sliding time is less than 6 seconds, which is sufficient for demagnetization), the stopper 4 blocks the bearing and makes it stay in the channel for the time required for demagnetization before releasing it.
[0026] Further, the stopper block 4 is connected to the air cylinder 3, and the air cylinder 3 is driven to extend into the fixed guide rail 5 or retract to make the stopper block 4 leave the fixed guide rail 5 through the solenoid valve installed on the solenoid valve bracket 1. The air cylinder 3 is installed on the air cylinder bracket 2.
[0027] Furthermore, the base 7 is connected with a V-shaped bracket 8, and the two fulcrums of the V-shaped bracket 8 are fixed to the bottom of the base 7. The inclination angle of the mounting surface 71 can be adjusted by changing the mounting angle between the V-shaped bracket 8 and the external device 9. Specifically in this embodiment, the apex of the V-shaped bracket 8 has a plurality of waist-shaped holes 81. When the bolts pass through the waist-shaped holes and are locked with the external device 9, the two brackets of the V-shaped bracket 8 can be formed in different positions, thereby changing the inclination angle of the mounting surface 71, so that the sliding time of the bearing in the fixed guide rail is adjusted.
[0028] The angle of inclination of the mounting surface 71 can be adjusted, which allows for finer control of the speed at which the bearing passes through the demagnetization device. Depending on the size and type of bearing, the angle can be adjusted to optimize the demagnetization time and effect, ensuring that each bearing is properly treated.
[0029] The stopper 4 at the lower end of the fixed guide rail 5 is displaceable to control the passage or stay of the bearing. When the sliding speed of the bearing is too fast, which may lead to incomplete demagnetization, the stopper 4 can move to temporarily block the bearing to ensure that the bearing stays in the channel 61 for a sufficient time to complete the demagnetization.
[0030] The stopper 4 is driven by the air cylinder 3, which is controlled by the solenoid valve mounted on the solenoid valve bracket 1. This arrangement allows the stopper to move quickly and accurately, and can be adjusted in real time according to the actual situation of the bearing, whether it is extended into or retracted into the fixed guide rail 5.
[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.
