Description

Technical Field

[0001] This utility model belongs to the field of mechanical processing technology, and in particular relates to a riveting device for a brake rotor. Background Technology

[0002] In the manufacturing process of the door brake rotor, the connection between the rotor and the armature is usually achieved using a press-fitting process. Traditionally, this is done manually or with semi-automatic equipment.

[0003] The top of the existing rotor usually requires multiple riveting parts. However, due to the uneven structure of the rotor top, the riveting operation is usually achieved by adjusting the position of the pressure head on the riveting equipment or adjusting the position of the rotor.

[0004] In the existing technology, multiple actions are required to achieve all the riveting, which is inefficient. In addition, the side walls and bottom of the rotor are usually cylindrical, which makes it difficult to position the rotor without special concave and convex structures. Utility Model Content

[0005] The purpose of this invention is to provide a riveting device for a brake rotor to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, one technical solution adopted by this utility model is: a riveting device for a brake rotor, comprising a worktable, on which a press, a workpiece positioning fixture, an image acquisition device, and a fixture angle adjustment assembly are mounted;

[0007] The press includes a lifting assembly and a press head located at its common working end, the number of press heads being consistent with the number of riveted parts to be pressed on the rotor;

[0008] The workpiece positioning fixture is used to fix the workpiece;

[0009] The image acquisition device is used to acquire real-time position information of the riveted part on the rotor;

[0010] The tooling angle adjustment component can control the workpiece positioning tooling to rotate in the horizontal direction so that the part to be riveted on the rotor can correspond to the pressure head and complete the riveting work.

[0011] Preferably, the workbench is further provided with a tooling moving component, which is used to control the movement of the workpiece positioning tooling between the pressure head and the image acquisition device.

[0012] Preferably, the tooling adjustment assembly includes a lifting assembly and a rotating assembly placed at its working end. The working end of the rotating assembly is provided with a connector, and a connecting groove for use with the connector is provided below the workpiece positioning tooling.

[0013] Preferably, the workpiece positioning fixture includes a fixed seat, a rotating seat, and a clamping assembly. The fixed seat has a rotating groove, and the rotating seat rotates within the rotating groove. The clamping assembly includes an arc-shaped clamping block one, an arc-shaped clamping block two, and a clamping drive assembly. The arc-shaped clamping block one and the clamping drive assembly are both mounted on the rotating seat. The clamping drive assembly is used to control the arc-shaped clamping block two to move closer to or further away from the arc-shaped clamping block one to complete the clamping and releasing states of the rotor. The connecting groove is formed on the bottom surface of the rotating seat.

[0014] Preferably, the edges of the surfaces where the connector and the connecting groove are inserted into each other are beveled.

[0015] Preferably, the connector and the connecting groove are connected by a spline structure.

[0016] Preferably, the rotating seat is attached to the bottom wall of the rotating groove, the fixed seat has a through groove extending into the rotating groove to facilitate the entry of the connector, and ball bearings are provided between the side wall of the rotating groove and the side wall of the rotating seat.

[0017] Preferably, the workbench is equipped with a sensor for detecting the movement position of the tooling moving component.

[0018] Preferably, the pressure head is detachably connected to the lifting assembly.

[0019] Preferably, the first arc-shaped clamping block is detachably connected to the rotating seat, and the second arc-shaped clamping block is detachably connected to the clamping drive assembly.

[0020] The beneficial effects of this utility model are as follows: This solution uses the image acquisition device and the tooling angle adjustment component together to adjust the angle of the workpiece positioning tooling so that the part to be riveted on the rotor can be adjusted to the position aligned with each pressure head during the pressing process, so that the riveting of all the parts to be riveted can be completed at one time, and effectively overcomes the problem of not being able to effectively position the outer wall of the rotor and other cylindrical structures.

[0021] In this solution, the workpiece positioning fixture is controlled to move between the pressure head and the image acquisition device by the tooling moving component, so that the workpiece positioning fixture can be moved to the position directly below the image acquisition device, thereby achieving the best image acquisition effect and ensuring the accuracy of rotor positioning.

[0022] Among them, the spline structure of the connector and the connecting groove make it easy to connect the two together;

[0023] Among them, ball bearings are provided between the side wall of the rotating groove and the side wall of the rotating seat. This allows the ball bearings to support the rotating groove and the rotating seat during the process of the rotating seat being lifted, so as to avoid damage and noise caused by the contact and friction between the rotating groove and the rotating seat due to unstable connection between the connector and the connecting groove.

[0031] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0032] Example:

[0033] See Figure 1 A riveting device for a brake rotor includes a worktable 1, on which a press 3, a workpiece positioning fixture 2, an image acquisition device 4, and a fixture angle adjustment assembly 5 are mounted.

[0034] The press 3 includes a lifting assembly 32 and a pressing head 31 located at its common working end. The number of pressing heads 31 corresponds to the number of riveted parts 9 on the rotor 8. For details, please refer to [reference needed]. Figure 2 , Figure 6 A bracket is fixed on the workbench 1, and a support plate 33 is fixed on the bracket. The image acquisition device 4 and the lifting assembly 32 are both fixed on the support plate 33. A mounting head 34 is fixed at the working end of the lifting assembly 32, and several pressure heads 31 are installed on the mounting head 34. The lifting assembly 32 can be a cylinder.

[0035] The workpiece positioning fixture 2 is used to fix the workpiece;

[0036] The image acquisition device 4 is used to acquire the real-time position information of the riveted part 9 on the rotor 8;

[0037] The tooling angle adjustment component 5 can control the workpiece positioning tooling 2 to rotate in the horizontal direction so that the part to be riveted 9 on the rotor 8 can correspond to the pressure head 31 and complete the riveting work.

[0038] Among them, see Figure 1 , Figure 2 The workbench 1 is also provided with a tooling moving assembly 6. The tooling moving assembly 6 is used to control the movement of the workpiece positioning tool 2 between the pressure head 31 and the image acquisition device 4. Specifically, the tooling moving assembly 6 includes a guide rail 63 installed on the workbench 1, and a moving slide 62 slides on the guide rail 63. The moving slide 62 is driven by a moving cylinder 61.

[0039] Among them, see Figure 1 , Figure 2 , Figure 4 , Figure 5 The tooling angle adjustment assembly includes a second lifting assembly 52 and a rotating assembly 53 placed at its working end. The working end of the rotating assembly 53 is provided with a connector 54. The workpiece positioning tooling 2 has a connecting groove 211 below it for use with the connector 54. The lifting assembly is fixed on the mounting base 51, and the mounting base 51 is fixed on the bottom surface of the worktable 1. The second lifting assembly 52 can be a cylinder, and the rotating assembly 53 can be a servo motor.

[0040] Among them, see Figure 3 Figure 4The workpiece positioning fixture 2 includes a fixed seat 21, a rotating seat 22, and a clamping assembly. The fixed seat 21 is fixed on the movable slide table 62. The fixed seat 21 has a rotating groove, and the rotating seat 22 can rotate within the rotating groove. The clamping assembly includes an arc-shaped clamping block 29, an arc-shaped clamping block 28, and a clamping drive assembly 27. The arc-shaped clamping block 29 and the clamping drive assembly 27 are both mounted on the rotating seat 22. The clamping drive assembly 27 is used to control the arc-shaped clamping block 28 to move closer to or further away from the arc-shaped clamping block 29 to complete the clamping and releasing states of the rotor 8. The connecting groove 211 is opened on the bottom surface of the rotating seat 22. The clamping drive assembly 27 can be a cylinder. In order to ensure the mechanical balance of the rotating seat 22 as much as possible, a counterweight 210 is also installed on the rotating seat 22 so that the center of gravity of the rotating seat 22 is as central as possible.

[0041] The edges of the surfaces where the connector 54 and the connecting groove 211 are inserted into each other are beveled, which facilitates the insertion of the connector 54.

[0042] The connector 54 and the connecting groove 211 are connected by a spline structure, and the more splines there are, the easier it is to connect them.

[0043] The rotating seat 22 is attached to the bottom wall of the rotating groove. The fixed seat 21 has a through groove that extends into the rotating groove to facilitate the entry of the connector 54. Of course, a through groove that allows the connector 54 to pass through also needs to be opened on the worktable 1. An annular rolling groove 25 is opened on the side wall of the rotating groove. Several inlet grooves 24 that connect to the rolling groove 25 are opened on the top surface of the fixed seat 21. A retaining groove 26 corresponding to the position of the inlet groove 24 is opened on the side wall of the rotating seat 22. A ball bearing 212 is installed in the retaining groove 26. During assembly, the ball bearing 212 is placed on the retaining groove 26, aligned with the inlet groove 24, and then the rotating seat 22 is inserted into the rotating groove. After the rotating seat 22 touches the bottom wall 23 of the rotating groove, the ball bearing 212 falls into the rolling groove 25. It should be noted that when designing the control program, the height at which the connector 54 lifts the rotating seat 22 should be lower than the distance from the ball bearing 212 to the top wall of the rolling groove 25.

[0044] The workbench 1 is equipped with a sensor 7 for detecting the movement position of the tooling moving component 6. The sensor 7 is located on both sides of the guide rail 63 along its length. The sensor 7 can be an infrared ranging sensor 7 or the like.

[0045] The pressure head 31 and the lifting assembly 32 are detachably connected, and can be connected by means of bolts or the like.

[0046] The arc-shaped clamping block 29 is detachably connected to the rotating seat 22, and the arc-shaped clamping block 28 is detachably connected to the clamping drive assembly 27. The two can be connected by bolts.

[0047] Working principle and process:

[0048] When using the equipment of this solution, the workpiece is placed on the rotating seat 22 and the rotor 8 is made to fit against the arc-shaped part of the arc-shaped clamping part 1. Then, the clamping drive assembly 27 controls the arc-shaped clamping part 1 to clamp the rotor 8. Subsequently, the image acquisition device acquires images, and the tooling angle adjustment assembly 5 controls the connector 54 to connect with the connecting groove 211 and makes the rotating seat 22 rise slightly. According to the data acquired by the image acquisition device 4, the tooling angle adjustment assembly 5 controls the connector 54 to rotate the corresponding angle to meet the riveting position. Subsequently, the tooling moving assembly 6 drives the workpiece positioning tool 2 to move below the press 3. The lifting assembly 32 controls the press 3 to press down, thereby realizing the riveting action on the part 9 to be riveted on the rotor 8. It should be noted that due to the influence of the clamping drive assembly circuit, after the tooling moving assembly 6 drives the workpiece positioning tool 2 to return to the initial position, the tooling angle adjustment assembly 5 should control the workpiece positioning tool 2 to reset.

Any equivalent structural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
