Description

Technical Field

[0001] The utility model relates to the technical field of bearing retainer processing, in particular to a bearing retainer processing deburring device. Background Art

[0002] The bearing cage, also known as the bearing retainer, refers to a bearing part that partially wraps all or part of the rolling elements and moves with them. It is used to isolate the rolling elements and usually guide the rolling elements and retain them in the bearing. In order to avoid affecting the movement of the rolling elements during the production process, the bearing cage usually requires a deburring device for deburring.

[0003] In the process of deburring the existing bearing cage, in order to ensure the effectiveness of the deburring process, it is usually necessary to limit the position of the bearing cage so that the cage can rotate but cannot escape from the deburring range of the deburring device. Therefore, the existing limiting method mostly adopts limiting clamping of the bearing cage, but the outer wall of the existing bearing cage is used to wrap the rolling element, and usually a plurality of spaces are opened at equal intervals, resulting in a small contact surface between the existing clamping structure and the outer wall of the cage, so that the cage is prone to shaking as the deburring device runs, thereby reducing the firmness of the cage position fixation, and further reducing the quality and efficiency of the cage deburring process.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] The utility model provides Figure 1-4 The bearing retainer processing and deburring device shown in the figure comprises a processing box 1, wherein the inner cavity of the processing box 1 is provided with a plurality of deburring structures 2 and a limiting structure 3.

[0021] First, the limiting structure 3 includes a first limiting rod 301, a second limiting rod 302 and a plurality of limiting blocks 305. The first limiting rod 301 and the second limiting rod 302 are both L-shaped. The top end of the first limiting rod 301 and the bottom end of the second limiting rod 302 are movably interlaced. The plurality of limiting blocks 305 are respectively fixed on the outer walls of the first limiting rod 301 and the second limiting rod 302. The limiting blocks 305 are located on the same vertical plane. A spring is fixed on the top end of the second limiting rod 302. The limiting structure 3 also includes a support plate 303 and a second motor 304. The support plate 303 is movably arranged in the inner cavity of the processing box 1 through the second motor 304, and the second motor 304 is fixedly arranged on one side of the processing box 1.

[0022] Secondly, if Figure 2 and Figure 3As shown in the figure, a strip groove is provided on the end surface of the support plate 303 away from the second motor 304, and the strip groove is used for installing the first limiting rod 301 and the second limiting rod 302 on the support plate 303. The spring fixedly arranged at the top of the second limiting rod 302 is fixedly arranged at the top of the inner cavity of the strip groove. The first limiting rod 301 is fixedly arranged in the inner cavity of the strip groove, and the second limiting rod 302 is movably arranged in the inner cavity of the strip groove through the spring, and the vertical inner cavity of the second limiting rod 302 is a cavity setting, so that the second limiting rod 302 When the rod 302 is under pressure, it can slide along the outer wall of the vertical rod body of the first limiting rod 301. When deburring the outer wall of the retainer, the setting of the limiting block 305 on the same vertical plane makes it possible for the bearing retainer to be sleeved on the ends parallel to the first limiting rod 301 and the second limiting rod 302. The force direction of the limiting block 305 is consistent with the force direction of the first limiting rod 301 and the second limiting rod 302, so that the interval space on the outer wall of the bearing retainer can be inserted, thereby strengthening the first limiting rod The expansion force of the positioning rod 301 and the second limiting rod 302 on the inner wall of the retainer, and the thickness of the limiting block 305 is less than the thickness of the retainer, so as to avoid affecting the deburring process of the outer wall of the retainer. After the retainer is fixed, the support plate 303 is driven to rotate by the second motor 304, and the rotation direction is opposite to the processing direction of the deburring structure 2, thereby ensuring the effectiveness and efficiency of the retainer deburring. On the contrary, when the inner wall of the retainer is deburred, the outer wall of the retainer is squeezed by the first limiting rod 301 and the second limiting rod 302. Similarly, the limit block 305 and the gap between the outer wall of the retainer are used to strengthen the restriction on the position of the retainer. Then, the support plate 303 is driven to rotate by the second motor 304, and the reverse movement of the retainer and the deburring structure 2 is indirectly driven. Thus, the deburring work of the inner and outer walls of the retainer is effectively limited. The gap on the retainer's own structure is used to cooperate with the setting of the limiting block 305 to limit its insertion. The structure is simple, the cost is low, and the practicability is strong.

[0023] Then, if Figure 2As shown in, the deburring structure 2 includes a grinding disc 201, a first motor 202, a stabilizing frame 203 and a cylinder 204. The top end of the grinding disc 201 is arranged for transmission with the output shaft of the first motor 202. The first motor 202 is fixedly arranged at the bottom end of the stabilizing frame 203. The stabilizing frame 203 is movably interlaced with the top end of the processing box 1 through the cylinder 204. The stabilizing frame 203 is concave-shaped. Both ends of the stabilizing frame 203 are movably interlaced with the outer wall of the processing box 1. While the stabilizing frame 203 provides position installation support for the first motor 202, it also improves the stability of the position movement of the first motor 202 and the grinding disc 201. The cylinder 204 is fixedly arranged at the top end of the processing box 1. The number of deburring structures 2 in this embodiment is two, and they are distributed in a vertical position on the processing box 1. With the cooperation of the two deburring structures 2, the outer wall and the inner wall of the retaining frame can be polished and deburred at one time. When the retaining frame is moved by the first limiting rod 301 and the second limiting rod After the positioning rod 302 and the limiting block 305 are fixed in position, the cylinder 204 can be started to drive the stabilizing frame 203 to descend, and the grinding disc 201 can be indirectly driven to descend until the grinding disc 201 is in contact with the top of the retaining frame. Then, the first motor 202 is started to drive the grinding disc 201 to rotate, and at the same time, the outer wall of the retaining frame can be polished and deburred with the reverse rotation of the retaining frame. Similarly, when deburring the inner wall of the retaining frame, the outer wall of the retaining frame is clamped by the first limiting rod 301, the second limiting rod 302 and the limiting block 305 to ensure the fixing of the position of the retaining frame. Then, the grinding disc 201 is first moved to the inner wall of the retaining frame, and then the first motor 202 is started to drive the grinding disc 201 to rotate, so that the inner wall of the retaining frame can be polished and deburred. The first motor 202 and the second motor 304 are both electrically connected to the external power supply through the external control switch.

[0024] Furthermore, a positioning structure 4 is arranged between the first limiting rod 301 and the second limiting rod 302, and the positioning structure 4 includes a positioning rod 401 and a plurality of positioning grooves 402, and the plurality of positioning grooves 402 are evenly spaced on the outer wall of the second limiting rod 302, the positioning rod 401 and the plurality of positioning grooves 402 are movably interlaced, and the positioning rod 401 is movably arranged on the outer wall of the first limiting rod 301, and the positioning structure 4 also includes a support spring 403 and a movable groove 404, and the movable groove 404 is arranged on the outer wall of the first limiting rod 301, and the support spring 403 is fixedly arranged in the inner cavity of the movable groove 404, and one end of the support spring 403 is fixedly arranged on the end of the positioning rod 401 away from the positioning groove 402.

[0025] Finally, if Figure 4As shown in the figure, the positioning rod 401 can move along the inner cavity of the movable groove 404 under the action of external force by being fixed with the support spring 403. In the absence of external force, the positioning rod 401 moves to align with the inner cavity of the positioning groove 402, and will automatically pop out and connect with the inner cavity of the positioning groove 402 by utilizing the elastic force of the support spring 403, so that the first limiting rod 301 and the second limiting rod 302 can limit the position by utilizing the insertion of the positioning rod 401 and the inner cavity of the positioning groove 402, so that the second limiting rod 302 can be fixed in position after the height is adjusted according to the different diameters of the retaining frame, so that it can be adapted to multiple The positioning rod 401 is used to limit the size of the retaining frame. At the same time, when the second limiting rod 302 slides along the outer wall of the first limiting rod 301, the positioning rod 401 will be squeezed by the inner wall of the second limiting rod 302 and move toward the inner cavity of the movable groove 404 using the compression performance of the support spring 403, thereby ensuring the flexibility of the second limiting rod 302 to move up and down. Furthermore, the limiting range of the first limiting rod 301 and the second limiting rod 302 is increased, so that the distance between the first limiting rod 301 and the second limiting rod 302 can be flexibly adjusted according to the different diameters of the retaining frame, which not only strengthens the limiting stability of the limiting structure 3, but also effectively improves the practicality of the limiting structure 3.
