Description

Technical Field

[0001] This utility model relates to the field of wheel hub processing equipment, specifically a wheel hub plug quick gripping mechanism. Background Technology

[0002] If the bolt holes of car wheel hubs are not shielded before painting, the paint may clog the threads, affecting subsequent installation. Professional masking materials (such as caps) must be used to tightly seal the bolt holes to prevent paint from seeping in.

[0003] Wheel hub painting is completed on an assembly line. Before painting, manual labor is required to insert plugs into the bolt holes. This process is labor-intensive, inefficient, and prone to errors, thus affecting the overall production rhythm of the assembly line. Currently, the diameter of the bolt hole distribution circle on the wheel hub varies for each car model (but the number of bolt holes is the same; most car models on the market currently have five bolt holes). The current robotic arm cannot quickly adapt to different wheel hub models, affecting work efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a quick-gripping mechanism for wheel hub plugs to solve the problem of low installation efficiency of existing wheel hub plugs.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a wheel hub plug quick-gripping mechanism, comprising: Mounting bracket, The gripper is slidably mounted on the mounting bracket; A synchronous drive component, mounted on the mounting frame, is used to drive several grippers to slide synchronously along the mounting frame; The synchronous drive component includes a vertical motion unit and a horizontal motion unit. The horizontal motion unit is connected to the gripper, and the vertical motion unit is connected to the horizontal motion unit.

[0006] Preferably, the up-and-down motion unit includes an actuator and a drive unit, the actuator and the drive unit are connected, the drive unit drives the actuator to move up and down, and the actuator drives the left-and-right motion unit to move left and right.

[0007] Preferably, the actuator is provided with a guide portion, and the left and right movement unit includes a support frame and a guide arm disposed on the support frame. One end of the guide arm is connected to the guide portion, and the other end is connected to the gripper.

[0008] Preferably, the guide arm is rotatably connected to the support frame, and the guide arm rotates about the hinge point of the support frame. The guide arm is rotatably mounted on the support frame by a pin, allowing the guide arm to rotate. Here, the guide arm needs to be set with a special shape, such as an L-shape, so that the rotational motion can be converted into the linear motion of the gripper.

[0009] Preferably, the guide arm is slidably connected to the support frame. A connecting rod is provided between the guide arm and the guide part, with both ends of the connecting rod hinged, and the movement of the connecting rod is converted into the linear movement of the guide arm.

[0010] Preferably, the guide arm and the guide portion are wedge-shaped, and one end of the guide arm is provided with an elastic reset mechanism. The wedge-shaped structure converts the linear motion of the guide portion into the linear motion of the guide arm.

[0011] Preferably, the driving component is one of a cylinder, a hydraulic cylinder, and a lead screw module. The driving component is used to move the guide section up and down, and therefore can be driven in various ways.

[0012] Preferably, the gripper is a multi-claw cylinder.

[0013] Preferably, the mounting bracket is provided with a housing on its outer side.

[0014] Preferably, a flexible material layer is provided on the outer side of the actuating end of the gripper.

[0015] Compared with the prior art, the beneficial effects of this utility model are: A synchronous drive assembly combining vertical and horizontal motion units efficiently converts the linear motion of the drive component into the synchronous radial motion of multiple grippers. This conversion mechanism is compact, has a short transmission chain, and responds rapidly, significantly reducing the action time for gripping and releasing wheel hub caps, thus substantially improving the overall cycle time and efficiency of the automated production line. Adjusting the drive parameters allows for quick adaptation to the installation of wheel hub caps of different sizes.

[0016] The centralized control method of one source and multiple drives ensures the synchronicity and consistency of the movement of each gripper, avoiding the risk of jamming, eccentricity or falling due to the asynchrony of multiple independent drive units, and ensuring that the gripping action of the wheel hub cover is stable, reliable and accurate.

[0017] The structure is compact and highly integrated. Through the force transmission of the guide arm, the vertical power is converted into the horizontal clamping force, which is convenient for installation and integration on automated equipment with limited space. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1 As shown, the wheel hub cap quick-gripping mechanism of this embodiment includes: Mounting bracket 1, in some embodiments, includes an upper plate and a lower plate, both used for mounting equipment, and a housing 5 is provided on the outside to ensure safety.

[0025] The gripper 2 is slidably mounted on the mounting bracket 1; the gripper 2 is a multi-jaw cylinder, generally a three-jaw finger cylinder.

[0026] A synchronous drive component is mounted on the mounting frame 1 to drive several grippers 2 to slide synchronously along the mounting frame 1. The synchronous drive component includes a vertical motion unit 3 and a horizontal motion unit 4. The horizontal motion unit 4 is connected to the gripper 2, and the vertical motion unit 3 and the horizontal motion unit 4 are connected.

[0027] like Figure 2 As shown, the up-and-down motion unit 3 includes an actuator 31 and a drive unit 32. The actuator 31 and the drive unit 32 are connected. The drive unit 32 drives the actuator 31 to move up and down, and the actuator 31 drives the left-and-right motion unit 4 to move left and right. Here, left-and-right motion refers to movement along the radial direction towards or away from the center of the circle.

[0028] like Figure 3 and Figure 4 As shown, the actuator 31 is provided with a guide part 311. The left and right motion unit 4 includes a support frame 41 and a guide arm 42 disposed on the support frame 41. One end of the guide arm 42 is connected to the guide part 311, and the other end is connected to the gripper 2. In this embodiment, the drive component 32 adopts a screw module, including a motor 321, a rotating screw 322, a threaded sleeve 323, a limiting guide block 324, and related connecting accessories (not limited to bearings, couplings, etc.). The rotating screw 322 is mounted on the mounting frame 1 through bearings. The motor 321 is mounted on the mounting frame 1. The output shaft of the motor 321 is connected to the rotating screw 322 through a coupling. The threaded sleeve 323 is threadedly engaged with the rotating screw 322. The guide part 311 is fixedly connected to the threaded sleeve 323. The limiting guide block 324 is slidably engaged with the guide part 311, so that when the rotating screw 322 rotates, it drives the guide part 311 to move up and down. The upper part of the gripper 2 is mounted on the mounting frame 1 through a cross roller guide structure 6.

[0029] like Figure 5 and Figure 6 As shown, the guide arm 42 is rotatably connected to the support frame 41, and the guide arm 42 rotates around the hinge point of the support frame 41. One end of the guide arm 42 has a spherical structure, and an annular groove is provided on the guide part 311. The spherical structure of the guide arm 42 is inserted into the annular groove, so that the guide arm 42 and the guide part 311 form a hinge structure. The other end is connected to the gripper 2 to form a hinge structure. Here, the rotation of the guide arm 42 is used to realize the displacement of the gripper 2.

[0030] In some embodiments, the guide arm 42 is slidably connected to the support frame 41. The guide arm 42 is a connecting rod, and the movement of the connecting rod driven by the actuator 31 realizes the displacement of the gripper 2.

[0031] like Figure 7 As shown, in some embodiments, the guide arm 42 and the guide portion 311 are wedge-shaped, and one end of the guide arm 42 is provided with an elastic reset mechanism. When the guide portion 311 moves downward, it drives the guide arm 42 to move outward. When the guide portion 311 moves upward, the elastic reset mechanism drives the guide arm 42 to return to its original position. The elastic reset mechanism is usually a spring, which can achieve the return (the installation position of the spring can be set according to requirements to ensure that the guide arm 42 can return to its original position after the guide portion 311 is no longer compressed).

[0032] It should be noted that in other embodiments, the drive component 32 may also be a linear module such as a cylinder or hydraulic cylinder, which can drive the actuator 31 to move up and down.

[0033] To prevent the metal grippers from damaging the gripping area, a flexible material layer is provided on the outside of the actuating end of the gripper 2. The flexible material layer is not limited to soft materials such as silicone or rubber.

[0034] Taking the lead screw module as an example, during use, the position of the clamp 2 is adjusted according to the wheel hub mounting position to clamp the plug and install it into the mounting position. During adjustment, the drive motor 321 rotates, driving the lead screw 322 to move, causing the threaded sleeve 323 to move. Since the stroke of the threaded sleeve 323 is related to the displacement of the clamp 2 (which can be calculated through multiple experiments), controlling the stroke of the motor 321 adjusts the position of the clamp 2. This utility model adopts a centralized control method with one source and multiple drives, ensuring the synchronization and consistency of the movement of each clamp, and can quickly adapt to the installation of wheel hub plugs of different sizes. It solves the problem of low installation efficiency of existing wheel hub plugs.

[0035] The above description is merely an embodiment of this utility model, and common knowledge regarding specific structures and characteristics is not described in detail here. It will be apparent to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this utility model is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this utility model.
