Description

Technical Field

[0001] This utility model relates to the field of jig technology, and in particular to a pneumatic swing jig. Background Technology

[0002] Fixtures are special fixtures used to hold and position specific components or products. They are widely used in industries such as electronics, machinery and automobile manufacturing. They are usually made of materials such as metal, plastic or wood and are designed to improve production efficiency and quality. Fixtures can be divided into process assembly type, project testing type and circuit board testing type. During the processing, fixtures are not only used to fix the workpiece, but also play an auxiliary role in guiding the processing.

[0003] Conventional fixtures typically use horizontal displacement in the X and Y directions for clamping and positioning. However, when visually inspecting the workpiece, the clamping arms can cause horizontal obstruction. For example, when the visual inspection camera takes a picture of the workpiece in the X direction, the clamping components in the X direction will block the side of the workpiece, affecting the comprehensiveness of the visual inspection. Similarly, a similar occlusion problem will occur when taking a picture of the workpiece in the Y direction. Utility Model Content

[0004] The purpose of this utility model is to provide a pneumatic swing fixture that can effectively avoid the obstruction of the same-direction grippers during visual inspection, ensure comprehensive visual inspection of the workpiece under test, and improve the accuracy and efficiency of visual inspection.

[0005] To achieve the above objectives, a pneumatic swing fixture is provided, comprising: a mounting base, first supports symmetrically arranged on the front and rear sides of the mounting base, and second supports symmetrically arranged on the left and right sides of the mounting base. A first clamping part is rotatably connected to the first support, and a second clamping part is rotatably connected to the second support. A first cylinder is provided on the mounting base, and a second cylinder is provided on the second support. By setting the grippers in the X and Y directions to perform a lifting and flipping motion, the fixture alternately clamps the workpiece to be tested. This effectively avoids obstruction by grippers in the same direction during visual inspection. When the visual inspection camera is taking pictures of the workpiece in the X direction, the workpiece can be clamped by the first clamping part and the second clamping part can be released, thus not hindering the X-direction inspection. Similarly, when it is necessary to take pictures of the workpiece in the Y direction, the workpiece is clamped by the second clamping part first and the first clamping part is released, ensuring comprehensive visual inspection of the workpiece and improving the accuracy and efficiency of visual inspection.

[0006] According to the pneumatic swing fixture, the middle part of the first clamping part is provided with a connecting rod, and the connecting rod is connected to a slide mounted on a second cylinder.

[0007] According to the pneumatic swing fixture, the second cylinder drives the connecting rod to pull back the first clamping part and make it snap upward and inward by controlling the relative displacement of its upper slide.

[0008] According to the pneumatic swing fixture, the middle part of the second clamping part is provided with a connecting rod, which is connected to the upper part of the first support.

[0009] According to the pneumatic swing fixture, the bottom end of the first clamping part is rotatably fitted with a crossbar in the front-back direction, and a slider is installed on the first cylinder to connect with the crossbar at the bottom end of the first clamping part.

[0010] According to the pneumatic swing fixture, the first cylinder pushes the crossbar at the lower part of the first clamping part by controlling the relative displacement of its upper slide, thereby driving the connecting rod to make the first clamping part snap upward and inward.

[0011] According to the pneumatic swing fixture, the top of the mounting base is symmetrically fixed with a bearing seat at the front and back, and the top of each bearing seat is symmetrically equipped with a suction cup at the left and right sides.

[0012] According to the pneumatic swing fixture, when the second clamping part is released and lowered from the first clamping part, the top of its jaws is located on the lower side of the support seat.

[0013] According to the pneumatic swing fixture, the second clamping part and the first clamping part are Z-shaped or S-shaped.

[0014] According to the pneumatic swing fixture, the second cylinder is located above the first cylinder.

[0015] According to the pneumatic swing fixture, the first cylinder and the second cylinder can be bidirectional cylinders.

[0016] The above-mentioned solution has the following beneficial effects:

[0017] In this invention, by setting grippers in the XY directions to perform a lifting and flipping motion to alternately clamp the workpiece to be tested, the obstruction of grippers in the same direction during visual inspection can be effectively avoided. When the visual inspection is taking pictures of the workpiece in the X direction, the workpiece can be clamped by the first clamping part and the second clamping part can be released, so as not to hinder the X-direction inspection. Similarly, when it is necessary to take pictures of the workpiece in the Y direction, the workpiece is clamped by the second clamping part first and the first clamping part is released, ensuring that the workpiece to be tested can be fully visually inspected, thereby improving the accuracy and efficiency of visual inspection.
