Description

TECHNICAL FIELD

[0001] The application relates to the technical field of bearing riveting, in particular to a riveting device and a hub bearing riveting equipment. BACKGROUND

[0002] In the production and manufacturing of hub bearings, a riveting process (such as the assembly of a hub bearing retainer) needs to be performed, so that the hub bearing unit is made more compact and good pre-tightening force is generated, thereby improving the reliability and service life. When the riveting is performed, there is a risk that scratches will be caused on the surface of the hub bearing. Therefore, a good design of the riveting head and reasonable process parameters are the key to improving the riveting quality.

[0003] In the prior art, after the hub bearing is processed through a front-end process, it is transferred to a riveting station of a riveting device and is riveted by a riveting head. After the riveting is completed, the hub bearing is transferred to a rear end for processing of a next process. However, when the hub bearing is transferred by the riveting device, a pushing type or a conveying belt type transfer mode is usually adopted. In the pushing type transfer mode, sliding friction is generated between the lower surface of the hub bearing and the table top of the workbench, so that scratches are easily caused on the lower surface of the hub bearing. In the conveying belt type transfer mode, the positioning accuracy is low, and a positioning mechanism needs to be additionally provided, thereby increasing the equipment investment cost. Therefore, there is an urgent need for a riveting device to reduce the risk of scratches caused on the hub bearing in the transfer process and to improve the transfer accuracy of the hub bearing.

Two sliding grooves 613 are formed in the surface of the rotating disc 61, the clamping strip 62 is provided with two clamping strips and is correspondingly arranged with the two sliding grooves 613, and one end of each clamping strip 62 is slidably installed in the corresponding sliding groove 613. A reset spring 622 is installed between each clamping strip 62 and the rotating disc 61, and the reset spring 622 always forces the two clamping strips 62 to move away from each other.

[0042] The second clamping block 623 is fixedly installed at the end of each clamping strip 62 away from the rotating disc 61, and has the same structure as the first clamping block 313. The specific structure of the second clamping block 623 is referred to the structure of the first clamping block 313. The second clamping blocks 623 of the two clamping strips 62 form a second clamping area 621 for clamping the hub bearing flange plate.

A second driving member is arranged on the mounting seat 5 to drive the two clamping strips 62 to move close to each other. In the embodiment, the second driving member includes a pushing block 63, a lead screw 64 and a motor 65. The side wall of the mounting seat 5 close to the rotating disc 61 is provided with a mounting groove 55. The two ends of the lead screw 64 are rotatably installed in the mounting groove 55 and extend along the length direction of the transfer table 1. The pushing block 63 is provided with two pushing blocks 63 corresponding to the two clamping strips 62. Each pushing block 63 is connected with a connecting frame 631. The end of the connecting frame 631 away from the pushing block 63 extends into the mounting groove 55.

The two pushing blocks 63 are slidably installed in the mounting groove 55 of the mounting seat 5 through the respective connecting frames 631.

[0044] In the embodiment, the lead screw 64 is threadedly connected with the connecting frames 631 of the two pushing blocks 63 (the thread is not shown in the figure).

[0048] The rotating disk 61 is elliptical and has a major axis and a minor axis (the major axis and minor axis of the ellipse are common knowledge and will not be elaborated on here, and are not specifically marked in the figure). When the major axis of the rotating disk 61 rotates from the horizontal direction to the vertical direction, the bottom plate 51 and the top plate 52 move away from each other; when the major axis of the rotating disk 61 rotates from the vertical direction to the horizontal direction, the bottom plate 51 and the top plate 52 move closer to each other.

[0049] In order to improve the stability of the base plate 51, in other embodiments, a spring can be added between the base plate 51 and the mounting seat 5 to support the base plate 51 through the spring, so as to reduce the weight borne by the guide ball 54 of the base plate 51, thereby reducing the possibility of structural deformation of the guide ball 54 of the base plate 51.

[0050] The implementation principle of Example 2 of the present application is as follows: after the wheel hub bearing is transferred to the base plate 51 and the upper surface of the wheel hub bearing is inspected by the first probe 13, the two pushing blocks 63 are driven close to each other to force the second clamping blocks 623 of the two clamping bars 62 to clamp and fix the wheel hub bearing, and then the rotating disk 61 is driven to rotate to drive the wheel hub bearing to turn over, so that the first probe 13 can inspect the lower surface of the wheel hub bearing.

[0051] The guide ring groove 611 and the guide ball 54 are set to "connect in series" the rotating disk 61, the bottom plate 51 and the top plate 52, so that when the long axis of the rotating disk 61 rotates from the horizontal direction to the vertical direction, the rotating disk 61 can force the bottom plate 51 and the top plate 52 to move away from each other, providing avoidance space for the turning over of the hub bearing, thereby reducing the possibility of interference between the hub bearing and the bottom plate 51 during the turning over process of the hub bearing.

[0052] During rotation of the rotating disc 61, the two push blocks 63 and the two limiting blocks 53 combine to form a ring-shaped limiting ring, so that when the rotating disc 61 rotates, the inner circumferential wall of the limiting ring can limit the two clamping strips 62, so that the two clamping strips 62 keep the clamping effect on the hub bearing, thereby reducing the possibility that the two clamping strips 62 loosen during rotation of the rotating disc 61, and the hub bearing falls off, and improving the turnover effect of the overall structure.

[0053] Embodiment 3: The embodiment of the present application discloses a spin riveting device.

[0054] The spin riveting device disclosed by the embodiment of the present application is different from the embodiment 2 in that: Refer to Figure 9 The side plate 7 is installed in the flaw detection station 12 and located on one side of the bottom plate 51. The second probe (not shown in the figure) is installed on the side wall of the bottom plate 51 close to the side plate 7. The second probe is used for flaw detection on the outer circumferential wall of the hub bearing and is a visual camera.

[0055] In the embodiment, the upper surface of the bottom plate 51 is rotationally installed with a rotating plate 8. The hub bearing is placed on the rotating plate 8 and coaxial with the rotating plate 8. The upper surface of the bottom plate 51 is slidably installed with two sliding strips 511. The two sliding strips 511 are correspondingly arranged with the two clamping strips 62. The top wall of each sliding strip 511 is fixedly installed with a push strip 512. The push strip 512 is vertically arranged. The upper end of the push strip 512 is used for pushing the clamping strip 62. When the two clamping strips 62 are close to each other, the clamping strip 62 pushes the push strip 512 of the corresponding sliding strip 511 to force the corresponding sliding strip 511 to slide along the length direction of the sliding strip 511.

[0056] The outer circumferential wall of the rotating plate 8 is coaxially fixed with a linkage gear (not shown in the figure). Each sliding strip 511 is fixed with a linkage rack (not shown in the figure) close to the side wall of the rotating plate 8. The length direction of the linkage rack is consistent with the length direction of the sliding strip 511. The linkage racks of the two sliding strips 511 are in meshing transmission with the linkage gear, so that when the two clamping strips 62 are close to or away from each other, the rotating plate 8 can drive the hub bearing to rotate around the central axis of the rotating plate 8.

[0057] The implementation principle of the embodiment 3 of the present application is as follows: after the hub bearing is placed on the rotating plate 8 and the upper surface of the hub bearing is flaw detected by the first probe 13, the two clamping strips 62 are driven to be close to each other to clamp the hub bearing. During the sliding process of the clamping strip 62, the corresponding sliding strip 511 is pushed, so that the rotating plate 8 is forced to rotate, so that the second probe can comprehensively detect the circumferential wall of the hub bearing. When the clamping blocks of the two clamping strips 62 clamp the hub bearing, the hub bearing can be turned over, so that the lower surface of the hub bearing can be finally flaw detected, and the comprehensiveness of the flaw detection of the hub bearing is improved.

[0058] Embodiment 4: The embodiment of the present application discloses a hub bearing riveting device.

[0059] The hub bearing riveting device comprises a riveting workbench and the hub bearing riveting device described above, and the transfer table 1 is fixedly installed on the upper surface of the riveting workbench.

[0060] The above is the preferred embodiment of the present application, which does not limit the protection scope of the present application, so that: any equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
