Technical Field
[0001] This utility model relates to the field of gripper technology, specifically a gripper for positioning automotive parts. Background Technology
[0002] As a core piece of equipment in automated production, the automotive parts positioning gripper is made of high-strength alloy steel and carbon fiber composite materials, possessing high rigidity and lightweight characteristics. Its structural design includes multi-degree-of-freedom joints, flexible clamping modules, and a force feedback system. It achieves precise positioning and adaptive gripping through servo motors and pneumatic components. Built-in vision recognition and laser rangefinder sensors can detect the position and posture of the workpiece in real time. In conjunction with a PLC control system, it completes processes such as gripping, handling, and assembly. It is suitable for the flexible production of irregularly shaped parts such as engine blocks, gearbox gears, and body stamping parts, meeting the needs of modern automotive manufacturing with high cycle time and high repeatability positioning accuracy.
[0003] However, it still has some drawbacks. For example, when the automotive parts positioning gripper grips large parts, it usually uses external clamping or fixed fixtures, which is difficult to adapt to hole structures of different sizes, resulting in insufficient positioning accuracy and low gripping efficiency. Traditional fixtures need to be pre-adjusted and cannot adapt to the inner wall of the hole. For gripping irregular or deep hole parts, there are problems of cumbersome operation and poor stability.
[0004] To address the aforementioned issues, this application proposes a dedicated gripper for positioning automotive parts. Summary of the Invention
[0005] The purpose of this utility model is to provide a special gripper for positioning automotive parts, so as to solve the problem mentioned in the background art of difficulty in adapting to hole structures of different sizes.
[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a special gripper for positioning automotive parts, comprising a main body of a positioning gripper device, with a gripper extension rod movable below the main body of the positioning gripper device, and two sets of gripper extension rods provided in mirror image correspondence. Built-in expandable gripper control motors are installed on the outer sides of the two sets of gripper extension rods. These built-in expandable gripper control motors facilitate the gripping of larger parts by inserting them into holes in the parts, subsequently releasing the expandable gripper to grip and move the parts for processing. This design improves the gripping efficiency of large parts, and its adaptive hole gripping method avoids the positioning errors of traditional fixtures.
[0007] Preferably, a steering connection device is installed on the top of the main body of the positioning gripper device, and a heat dissipation device is fixedly connected to the front of the main body of the positioning gripper device.
[0008] Preferably, a horizontal moving motor is installed on the right side of the main body of the positioning gripper device, an operation panel is installed on the left side of the main body of the positioning gripper device, and extendable grippers are movable on both sides below the two sets of gripper extension rods.
[0009] Preferably, a linkage rod is installed on one side of the horizontal moving motor. The linkage rod is movable inside the main body of the positioning gripper device. A rotating bearing is installed on one side of the linkage rod. Threaded layers are installed on both sides of the linkage rod, and the threaded layers are mirror images of each other. An internal threaded cylinder is engaged on the surface of the threaded layer, and the internal threaded cylinder is movable inside the main body of the positioning gripper device.
[0010] Preferably, a gripper extension rod is fixedly connected below the internally threaded cylinder, a longitudinal linkage gear is installed on one side of the built-in expandable gripper control motor, the longitudinal linkage gear moves inside the gripper extension rod, a transverse linkage gear meshes on one side of the longitudinal linkage gear, and a rotating extension rod is fixedly connected below the transverse linkage gear.
[0011] Preferably, a short gear is fixedly connected below the rotating extension rod. The short gear moves inside the gripper extension rod. Toothed plate devices mesh on both sides of the short gear, and there are two sets of toothed plate devices that are mirror-corresponding. An expandable gripper is fixedly connected to one side of each set of toothed plate devices. Telescopic limit blocks are fixedly connected to both sides of each expandable gripper, and each pair of expandable grippers is mirror-corresponding. When using this device, after the gripper extension rod is inserted into the hole of a large component, the built-in expandable gripper control motor starts, driving the transverse linkage gear to rotate through the longitudinal linkage gear, which in turn drives the rotating extension rod and the short gear to rotate. The short gear meshes with the mirror-symmetrical toothed plate devices on both sides, pushing the two sets of expandable grippers to expand outward synchronously along the guide of the telescopic limit blocks, thereby achieving an adaptive gripping action against the inner wall of the hole.
[0012] Compared with the prior art, the beneficial effects of this utility model are: This utility model features a detachable moisture-proof board. The detachable design allows for quicker maintenance and replacement of the self-adhesive soft moisture-proof layer built into the detachable moisture-proof board when used inside a cold storage facility. This reduces the time and cost associated with maintenance. Attached Figure Description
