Description

Technical Field

[0001] The utility model relates to a bearing processing and flipping mechanism, belonging to the field of bearing processing. Background Technique

[0002] During the processing of bearings, it is necessary to process the two sides of the bearings. After the bearings are placed on the conveyor line, the conveyor line drives the bearings to transfer. When the bearings are conveyed between the two chucks, the chucks installed on the pneumatic grippers control the reduction of the distance between them, so that the two chucks clamp the bearings. Then, the servo motor drives the pneumatic gripper to rotate 180°, so as to realize the flipping of the bearings. When the bearings are being flipped, there is a situation where the bearings fall from the gap between the two chucks, resulting in poor flipping stability of the bearings. Therefore, it is necessary to design a bearing processing and flipping mechanism to prevent the bearings from falling during the flipping process. Content of the Utility Model

[0003] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a bearing processing and flipping mechanism to solve the problems put forward in the above background technique. The utility model prevents the bearings from falling during the flipping process.

[0004] In order to achieve the above purpose, the utility model is realized by the following technical scheme: a bearing processing and flipping mechanism, including a servo motor, a pneumatic gripper is installed on the output shaft of the servo motor. On the side of the pneumatic gripper away from the servo motor, there are two chucks for clamping the bearings and located in the gap of the conveyor line. The two chucks are fixedly connected to the two jaw parts of the pneumatic gripper. One side of the chuck is provided with a plurality of strip-shaped openings arranged at equal intervals in a ring shape. The strip-shaped openings are arranged along the radial direction of the chuck. A stud for restricting the position of the bearing is inserted into the strip-shaped opening. One end of the stud outside the two chucks is threadedly connected with a first nut, and one end of the stud between the two chucks is threadedly connected with a second nut. A support member for generating a gap between the first nut and the chuck is sleeved on the stud.

[0005] Further, the support member includes a support ring. A support ring is provided between the first nut and the chuck. The support ring is sleeved on the stud. On the side of the support ring away from the first nut, a plurality of support rods are installed at equal intervals in a ring shape. One end of the support rod away from the support ring is inserted into the chuck.

[0006] Further, a plurality of threaded blind holes are arranged at equal intervals in a ring shape on the side of the support ring facing the chuck. One end of the support rod is processed with an external thread, and the end of the support rod processed with the external thread is threadedly connected in the threaded blind hole.

[0007] Further, a support plate is fixedly connected to the circumferential side of the chuck. The support plate is arranged along the radial direction of the chuck. The support plate and the chuck are of an integrally formed structure. The support plate is fixedly connected to the jaw part of the pneumatic gripper through a plurality of second screws.

[0008] Further, a connection plate is installed at the output end of the servo motor, and the connection plate is fixedly connected to the pneumatic gripper through a plurality of first screws.

[0009] Further, a convex disk matching with the connection plate is fixedly connected to one side of the pneumatic gripper facing the servo motor, and the first screw passes through the small hole on the connection plate and is threadedly connected to the convex disk.

[0010] Advantages of the utility model:

[0011] 1. In the utility model, stud bolts are inserted into the strip-shaped openings on the same side of the two clamping plates, and the relative positions of the stud bolts and the clamping plates are restricted by the first nut and the second nut. Thus, the stud bolts on the two clamping plates play a role in restricting the position of the bearing. The bearing enters between the two clamping plates from the side where the stud bolts are not installed on the two clamping plates. The pneumatic gripper contracts, the distance between the two clamping plates is reduced, and clamping of the bearing is achieved. At this time, one end of the stud bolt contacts the annular side surface of the bearing. During the process of the servo motor driving the pneumatic gripper to rotate, the stud bolt drives and lifts the bearing, playing a role in preventing the bearing from falling. After the pneumatic gripper rotates 180°, the bearing can continue to be transferred through the side where the stud bolts are not installed on the two clamping plates.

[0012] 2. According to the outer diameter of the bearing, the utility model adjusts the position of the stud bolt along the strip-shaped opening, so that the relative position between the stud bolt and the clamping plate meets the requirement of the outer diameter of the bearing, thereby meeting the needs of bearings with different outer diameters and expanding the scope of application.

[0013] 3. When the utility model restricts the relative position of the stud bolt and the clamping plate by using the first nut and the second nut, the structure formed by the support ring and the support rod is located between the first nut and the clamping plate. Furthermore, under the support of the support ring and the support rod, a gap is generated between the first nut and the clamping plate. When the first nut or the second nut and the stud bolt cannot be separated due to rust, the stud bolt can be cut off by using the distance between the first nut and the clamping plate, avoiding damage to components such as the clamping plate during the disassembly process.

[0021] See also Figure 1 The utility model provides a technical solution: a bearing processing turning mechanism, comprising a servo motor 1, a pneumatic clamp 4 is installed on the output shaft of the servo motor 1, wherein a connecting plate 14 is installed at the output end of the servo motor 1, and the connecting plate 14 is connected and fixed to the pneumatic clamp 4 through a plurality of first screws 2, that is, a convex plate 3 matching the connecting plate 14 is connected and fixed to the side of the pneumatic clamp 4 facing the servo motor 1, so that the first screw 2 passes through the small hole on the connecting plate 14 and is threadedly connected to the convex plate 3, on the one hand, the connection and fixation between the connecting plate 14 and the convex plate 3 is completed, and on the other hand, the thickness of the part where the first screw 2 is installed on the pneumatic clamp 4 is locally increased.

[0022] See also Figure 1 and Figure 3 Two chucks 8 for clamping bearings and located in the gap of the conveyor line are provided on the side of the pneumatic clamp 4 facing away from the servo motor 1. The two chucks 8 are connected and fixed to the two clamping jaws of the pneumatic clamp 4, that is, a support plate 6 is connected and fixed to the annular side of the chuck 8, and the support plate 6 is arranged along the radial direction of the chuck 8. The support plate 6 and the chuck 8 are an integrally formed structure, so that the support plate 6 is connected and fixed to the clamping jaw of the pneumatic clamp 4 by multiple second screws 5, thereby completing the assembly of the chuck 8 and the pneumatic clamp 4.

[0023] One side of the chuck 8 is provided with a plurality of strip-shaped openings 7 at equal intervals in a circular shape. The strip-shaped openings 7 are arranged along the radial direction of the chuck 8. A stud 13 for restricting the position of the bearing is inserted into the strip-shaped opening 7. One end of the stud 13 outside the two chucks 8 is threadedly connected with a first nut 9, and one end of the stud 13 between the two chucks 8 is threadedly connected with a second nut 12. The studs 13 are inserted into the strip-shaped openings 7 on the same side of the two chucks 8, and the relative positions of the studs 13 and the chucks 8 are restricted by the first nut 9 and the second nut 12. Thus, the studs 13 on the two chucks 8 play a role in restricting the position of the bearing. The bearing enters between the two chucks 8 from the side where the studs 13 are not installed on the two chucks 8. The pneumatic gripper 4 contracts, the distance between the two chucks 8 is reduced, and the bearing is clamped. At this time, one end of the stud 13 is in contact with the annular side of the bearing. During the rotation of the pneumatic gripper 4 driven by the servo motor 1, the stud 13 drives and lifts the bearing, playing a role in preventing the bearing from falling. After the pneumatic gripper 4 rotates 180°, the bearing can continue to be transferred through the side where the studs 13 are not installed on the two chucks 8. According to the outer diameter of the bearing, the position of the stud 13 is adjusted along the strip-shaped opening 7 so that the relative position between the stud 13 and the chuck 8 meets the requirements of the outer diameter of the bearing, thereby meeting the requirements of bearings with different outer diameters and expanding the applicable range.

A plurality of support rods 11 are installed at equal intervals in a circular shape on the side of the support ring 10 facing away from the first nut 9. One side of the support ring 10 facing the chuck 8 is provided with a plurality of threaded blind holes at equal intervals in a circular shape. One end of the support rod 11 is processed with an external thread, and the end of the support rod 11 processed with the external thread is threadedly connected into the threaded blind hole to complete the assembly of the support rod 11 and the support ring 10. The end of the support rod 11 away from the support ring 10 is inserted into the chuck 8. When the relative positions of the stud 13 and the chuck 8 are restricted by the first nut 9 and the second nut 12, the structure formed by the support ring 10 and the support rods 11 is located between the first nut 9 and the chuck 8. Furthermore, under the support of the support ring 10 and the support rods 11, a gap is generated between the first nut 9 and the chuck 8. When the first nut 9 or the second nut 12 and the stud 13 cannot be separated due to rust, the stud 13 can be cut off by using the distance between the first nut 9 and the chuck 8, avoiding damage to components such as the chuck 8 during the disassembly process.
