Description

Technical Field

[0001] This utility model belongs to the field of automotive parts processing technology, and in particular relates to a stable and reliable automotive parts fixture. Background Technology

[0002] A fixture is a device used in mechanical manufacturing to fix a workpiece in the correct position for processing or inspection; it is also called a clamp. In a broader sense, any device used to quickly, conveniently, and safely install a workpiece at any stage of the manufacturing process can be called a fixture. Automotive parts require clamping and fixing before processing.

[0003] Some hydraulic clamps can automatically clamp target automotive parts, reducing manual labor. However, hydraulic clamps can only maximize the contact area of ​​the target when the lever arm is parallel. Otherwise, the contact area is insufficient and the clamping force range is small, resulting in the problem of low clamping stability of conventional hydraulic clamps.

[0004] To address these issues, we propose a stable and reliable automotive parts fixture. Utility Model Content

[0005] The purpose of this invention is to solve the problem of low clamping stability of conventional hydraulic clamps, and to propose a stable and reliable clamp for automotive parts.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A stable and reliable automotive parts clamp includes a hydraulic rod with a fixed base externally connected to the hydraulic rod. An arc-shaped pressing block is fixedly connected to the upper end of the hydraulic rod. A clamping arm is rotatably mounted on the upper part of the fixed base, and the lower end of the clamping arm is in movable contact with the arc-shaped pressing block. A return spring is provided between the fixed base and the clamping arm, with one end fixedly connected to the fixed base and the other end fixedly connected to the clamping arm. A bolt is threaded onto the clamping arm. Driving the hydraulic rod to extend it causes it to act upwards on the arc-shaped pressing block, which in turn acts upwards on the clamping arm. The arc-shaped pressing block increases the stability of the contact area with the clamping arm, causing it to push the rear of the clamping arm upwards, thus causing the front of the clamping arm to swing downwards. The clamping arm then drives the bolt to clamp the target automotive parts. Tightening the bolt adjusts the fit between the clamping arm and the target automotive parts, thereby ensuring clamping stability.

[0008] Preferably, the fixed base includes a bearing and a base body, with the lower end of the bearing fixedly connected to the base body. The base body is welded to the target table surface, and the bearing guides the swing of the clamping arm.

[0009] Preferably, the clamping arm includes a rotating rod and a rotating shaft, with the rotating shaft fixedly connected to the middle of the rotating rod. A bearing guides the rotation of the rotating shaft, causing the rotating rod to rotate around the rotating shaft.

[0010] Preferably, the clamping arm further includes an arc-shaped block, which is fixedly connected to one end of the rotating rod. The arc-shaped block increases the roundness of the contact point between the clamping arm and the arc-shaped extrusion block.

[0011] Preferably, the arc-shaped extrusion block comprises a block body, the upper end of which has an arc-shaped surface. The arc-shaped surface increases the stability of the contact area between the arc-shaped extrusion block and the clamping arm.

[0012] Preferably, the bolt includes a threaded rod and a pressure plate, the pressure plate being fixedly connected to one end of the threaded rod. The pressure plate increases the contact area between the bolt and the target automotive component.

[0013] Preferably, the bolt includes a knob, which is fixedly connected to the end of the threaded rod facing away from the pressure plate. The knob increases the operating lever length of the threaded rod; turning the knob rotates the threaded rod, which then acts on the pressure plate, facilitating adjustment of the clamping and fixing position.

[0014] In summary, the technical effects and advantages of this utility model are as follows:

[0015] 1. Drive the hydraulic rod to extend, and use the hydraulic rod to act upward on the arc-shaped extrusion block. The arc-shaped extrusion block then acts upward on the clamping arm. The arc-shaped extrusion block increases the stability of the contact range with the clamping arm, causing the arc-shaped extrusion block to push the rear of the clamping arm upward, thereby causing the front of the clamping arm to swing downward. The clamping arm drives the bolt to press the target automotive parts. Tighten the bolt to adjust the matching degree between the clamping arm and the target automotive parts, thereby ensuring the pressing stability.

[0016] 2. Use a knob to increase the length of the threaded rod operating lever. Turning the knob drives the threaded rod to rotate, and the threaded rod acts on the pressure plate, making it easy to adjust the clamping and fixing position. Attached Figure Description
