Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of automation equipment, in particular to a ring body processing system and method. BACKGROUND

[0002] The vehicle hub bearing is composed of two ring bodies and rolling bodies. In the processing of the ring bodies, due to the limitation of product structure and use function, the effective contact area of the outer periphery and the inner periphery of the ring body is small. The traditional clamping equipment is difficult to achieve reliable grabbing by clamping the outer periphery or the inner periphery of the ring body, and cannot meet the stability requirement of the movement of the ring body in the processing. To solve this grabbing problem, a hook structure can be used as a grabbing execution component. The hook is designed to match the inner periphery of the ring body, hooks the specific part of the inner periphery of the ring body, and then moves the hook through the driving mechanism to realize the transfer of the ring body between different processing stations and ensure the continuous processing of the ring body.

[0003] However, the contact between the hook and the ring body in the prior art is limited to the local area of the inner periphery, the number of contact points is limited, and the effective limiting of the ring body in the circumferential and radial directions is lacking, which leads to the phenomenon that the ring body shakes easily during the movement of the hook due to inertia, external force disturbance and other factors; this shaking directly leads to the unexpected relative friction between the contact part of the ring body and the hook and the surrounding equipment components, and then generates additional wear, which affects the processing precision of the ring body and the use stability of the equipment.

[0044] During the processing of the ring body 60, the ring body 60 needs to be transferred between different processing stations or spaces through the lifting and moving assembly 20. In the traditional transfer mode, the contact between the lifting and moving assembly 20 and the ring body 60 is mostly limited to a partial area of the inner circumferential surface, and there is a lack of effective limiting structure in the circumferential and axial directions of the ring body 60, and there is no suitable space and transition structure that can guide the stable movement of the ring body 60. Due to the structural characteristics of the ring body 60 itself, when the ring body 60 follows the lifting and moving assembly 20 to move, it is easy to be affected by inertia, external disturbance and other factors to produce a rocking phenomenon. This rocking not only leads to the risk of the ring body 60 falling off the lifting and moving assembly 20, but also causes unintended relative contact and friction between the ring body 60 and the lifting and moving assembly 20 or the surrounding related components, thereby generating additional wear, which is a technical problem that needs to be solved during the transfer of the ring body 60.

[0045] Embodiment one: the embodiment discloses a ring body processing system, as shown in the figure, the ring body processing system comprises a ring body 60, a lifting and moving assembly 20 and a second displacement assembly 30. The second displacement assembly 30 comprises a first sliding unit 31 and a ring moving unit 33. The first sliding unit 31 semi-surrounds a first sliding space and provides a temporary placement and transition moving space for the ring body 60. Figure 1

[0046] A positioning assembly 40 comprises a circumferential positioning unit 41 and a positioning back plate 42. The first sliding unit 31 and the positioning back plate 42 are sequentially arranged. The circumferential positioning unit 41 and the positioning back plate 42 surround a positioning space. A first set sliding surface is arranged on the side of the first sliding unit 31 close to the positioning back plate 42. A set positioning surface is arranged on the side of the positioning back plate 42 close to the circumferential positioning unit 41. The first set sliding surface and the set positioning surface are smoothly connected, thereby reducing the frictional resistance when the ring body 60 moves. Further, as shown in the figure, the circumferential positioning unit 41 comprises a first positioning part 411 and a second positioning part 412, which are used for circumferential positioning of the ring body 60. Figure 2

[0047] The ring body 60 processing system comprises a lifting and moving state and a ring moving state. In the lifting and moving state, the lifting and moving assembly 20 abuts against the inner circumferential surface of the ring body 60, the lifting and moving assembly 20 moves the ring body 60 into the first sliding space, and then the lifting and moving assembly 20 is released and removed. The abutment between the lifting and moving assembly 20 and the inner circumferential surface of the ring body 60 can reliably grasp the ring body 60, and then the ring body 60 can be quickly moved into the first sliding space. The release and removal of the lifting and moving assembly 20 can avoid interference with the subsequent ring moving operation, and effectively meet the operation requirement of quick transfer in a long distance. In the lifting and moving state, the minimum angle between the axial direction of the ring body 60 and the horizontal direction is less than or equal to a third set angle. The third set angle can be 5°, 10° or 15°, so that the axial direction of the ring body 60 is parallel or close to parallel to the horizontal direction.

[0048] ​​The moving ring state includes that the moving ring unit 33 moves into the space surrounded by the inner circumferential surface of the ring body 60 in the first sliding space, the moving ring unit 33 drives the ring body 60 to move into the positioning space, at this time, the machining assembly 50 can process the ring body 60. The axial end of the ring body 60 abuts against the first set sliding surface and the set positioning surface in turn, and the outer circumferential side of the ring body 60 abuts against the circumferential positioning unit 41. Further, the entire inner circumferential surface of the ring body 60 abuts against the outer circumferential surface of the moving ring unit 33, and the limiting effect is better. By driving the moving ring unit 33 to extend into the inner circumferential surface space of the ring body 60, combined with the guidance of the first set sliding surface and the limiting effect of the positioning space, and the smooth transition of the first set sliding surface and the set positioning surface, the accurate positioning of the ring body 60 is realized, so as to reduce the shaking of the ring body 60 in the transfer process, and finally prevent the ring body 60 from being abraded additionally. Further, the machining assembly 50 includes a machining wheel 51, a rotating wheel driving part and a machining driving part. The rotating wheel driving part can drive the machining wheel 51 to rotate, and the machining driving part can drive the machining wheel 51 to move.

The first set sliding surface cooperates with the first abutting part 3321, and the set positioning surface cooperates with the first abutting part 3321, which can limit the movement range of the ring body 60 in the axial direction of the abutting module 332, and ensure the axial posture stability of the ring body 60 in the moving ring process. The second abutting part 3322 supports the ring body 60. Further, the connecting module 331 includes a connecting part 3311, an extension part 3312, an extension driving part and a connecting driving part.

[0053] Further, as shown in FIG. 1, the lifting and moving assembly 20 includes a lifting and moving assembly 20, a first sliding space 31 and a second sliding space 32. Figure 5As shown, H1≥0.7×D; to ensure that the first set of sliding surface has sufficient height space, meet the attitude requirements when the ring body 60 moves, and ensure smoothness. Preferably, H1≥D, the larger the contact area, which can make the ring body 60 close to the first set of sliding surface side force more reasonable. 0

[0054] The first claw 222 includes a first rod 2221 and a second rod 2222. One end of the first rod 2221 is movably connected to the lifting seat 221, and the other end extends away from the lifting seat 221, so that the second rod 2222 can be close to the inner circumferential surface of the ring body 60. One end of the second rod 2222 is connected to the end of the first rod 2221 away from the lifting seat 221, and the other end extends towards the second claw 223. At least the first rod 2221, the second rod 2222, and the second claw 223 surround the lifting and moving space;

[0055] The lifting and moving state further includes that the second rod 2222 abuts against the inner circumferential surface of the ring body 60, and the first rod 2221 and the second claw 223 are arranged on both sides of the ring body 60 in the axial direction, further improving the stability of the lifting and moving clamping, and limiting the movement range of the ring body 60 along the axial direction thereof.

[0056] Further, the first sliding unit 31 includes a first sliding channel 311 and a first limiting portion 312. The first sliding channel 311 surrounds the first sliding space to provide a transition moving channel for the ring body 60. The bottom surface of the first sliding space close to the side of the positioning back plate 42 (such as the right side as shown) is lower than the bottom surface of the first sliding space away from the side of the positioning back plate 42 (such as the left side as shown). Figure 4 The first sliding channel 311 is arranged on the first set of sliding surface, and the first limiting portion 312 is arranged on the side of the first sliding space away from the first set of sliding surface. Figure 4(As shown on the left); gravity assists the annular body 60 to move towards the positioning back plate 42, reducing the driving force requirement of the moving ring unit 33. The first limiting part 312 is slidably connected to the first slide rail 311 to temporarily limit the annular body 60; when the first limiting part 312 is in the first sliding space, it can restrict the movement of the annular body 60 towards the positioning component 40.
