Description

Technical Field

[0001] This utility model relates to the field of automotive parts manufacturing technology, specifically a double-sided welding fixture for automotive parts manufacturing. Background Technology

[0002] Welding fixtures are tooling equipment used to accurately position and reliably clamp workpieces, facilitating their assembly and welding, and ensuring the structural accuracy of the workpieces. Automotive parts manufacturers actively utilize welding fixtures adapted to the product structure in their welding production processes. This plays a crucial role in improving product quality, reducing worker workload, and accelerating the automation of welding production.

[0003] Automotive component welding fixtures are fixtures used during the welding process in automotive component production. They prevent automotive components from shaking during the welding process. In the automotive component welding process, after side A of the component is welded, side B also needs to be welded. Currently used fixtures require removing the frame after side A is welded, repositioning it, and then fixing it again, which is not convenient.

[0004] Therefore, a double-sided welding fixture for automotive parts production was designed based on the above technical problems. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology and solve the problems mentioned in the background technology, this utility model proposes a double-sided welding fixture for the production of automotive parts.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a double-sided welding fixture for automobile parts production, including a frame, the frame including a first upright and a second upright arranged opposite to each other, a clamping and rotating assembly is provided on one upright and a rotating mechanism is provided on the other upright.

[0007] The clamping and rotating assembly includes a clamping assembly and a rotating assembly. The rotating assembly includes a rotating disk and a rotating frame. The rotating frame drives the rotating disk to rotate. The clamping assembly is connected to the rotating disk. The rotating frame includes a transmission assembly and a drive assembly.

[0008] The rotating mechanism includes: a second clamping assembly connected in sequence, the second clamping assembly rotating relative to the second upright via a bearing, the bearing passing through the second upright, and a locking mechanism provided on the bearing;

[0009] The heights of the clamping assembly and the second clamping assembly are consistent.

[0010] The transmission assembly includes a three-bar structure, with one end of the three-bar connected to the rotating disk and the other end connected to the drive assembly.

[0011] Working principle: When a workpiece needs to be welded, it is first clamped on the frame by the clamping and rotating assembly and the rotating mechanism. The workpiece is further locked by the locking mechanism to prevent it from rotating. Then, the workpiece A side is welded. The locking mechanism is opened, and then the clamping and rotating assembly drives the transmission assembly through the drive assembly to rotate the clamping assembly and the rotating assembly. The clamping assembly drives the workpiece to rotate, so that the workpiece can be flipped. After the locking mechanism is locked, the workpiece B side is welded.

[0012] Preferably, a lifting platform is provided below the clamping assembly. When the workpiece is rotated, the lifting platform descends to ensure that the workpiece can rotate smoothly. When welding is required, the lifting platform rises to ensure that the workpiece can be placed smoothly on the lifting platform, avoiding the problem of the workpiece sliding down during the welding process due to gravity, and ensuring the stability of the workpiece position during the welding process.

[0013] Preferably, the lifting platform includes a placement platform and a cylinder disposed at the bottom of the placement platform, and the placement platform is located below the clamping assembly and the second clamping assembly.

[0014] Preferably, the lifting platform is provided with a limiting component, which includes multiple limiting baffles. The limiting baffles are located above the platform and can move on the platform. The rear side of the limiting baffle is connected to the second cylinder to further limit the workpiece.

[0015] Preferably, the drive assembly includes a driven gear, a drive gear, and a drive mechanism. The driven gear and the drive gear mesh with each other. The drive gear is connected to the drive mechanism, and the driven gear is connected to the transmission assembly. The meshing of the driven gear and the drive gear makes the drive assembly more stable during the process of driving the clamping assembly to rotate the workpiece, which makes the positioning more accurate and avoids the problem of workpiece displacement after rotation.

[0016] Preferably, the clamping assembly includes a pneumatic gripper, and the second clamping assembly includes a pneumatic gripper.

[0017] Preferably, both the pneumatic gripper and the workpiece contact area are provided with an elastic anti-slip layer to avoid damage to the workpiece and slippage during the gripping process.

[0018] Preferably, the drive mechanism includes a servo motor.

[0019] The advantages of this utility model are:

[0020] 1. In the process of welding automotive parts, when the welding of side A of the part is completed and side B still needs to be welded, this utility model uses a rotating clamping assembly to clamp and rotate the automotive parts, avoiding the need to remove the frame and reposition and fix it after welding side A. This improves efficiency and reduces labor costs. In addition, the rotation in this application;

[0021] 2. The clamping assembly of this utility model is provided with a lifting platform below it. When the workpiece is rotated, the lifting platform lowers to ensure that the workpiece can rotate smoothly. When welding is required, the lifting platform rises to ensure that the workpiece can be placed smoothly on the lifting platform, avoiding the problem of the workpiece sliding down during the welding process due to gravity, and ensuring the stability of the workpiece position during the welding process.

[0022] 3. The lifting platform of this utility model is provided with a limiting component, which includes multiple limiting baffles. The limiting baffles are located above the platform and can move on the platform. The rear side of the limiting baffle is connected to the cylinder, which further limits the workpiece and further ensures the stability of the workpiece. Attached Figure Description
