Description

Technical Field

[0001] This utility model belongs to the field of fixture technology, and in particular relates to a welding fixture. Background Technology

[0002] A fixture is a device used in mechanical manufacturing to fix a workpiece in the correct position for operation 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.

[0003] Because screw clamps require many turns to contact the target product and continue turning to clamp and fix it, while pull-type clamps have a relatively small clamping range, and since welding products do not require overcoming strong forces, quick clamping and clamping range are more important than firmness, resulting in the problem that conventional clamps are less effective for welding products.

[0004] To address this issue, we propose a welding fixture. Utility Model Content

[0005] The purpose of this utility model is to solve the problem that conventional fixtures are not very effective for welding products, and to propose a welding tooling fixture.

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

[0007] A welding fixture includes a guide frame. A toothed column is slidably mounted on the upper part of the guide frame. A toothed pin is provided on the side of the toothed column. The toothed column and the toothed pin are engaged and matched. The toothed pin is slidably mounted in the guide frame. A tension spring is provided between the guide frame and the toothed pin. One end of the tension spring is fixedly connected to the toothed pin, and the other end of the tension spring is fixedly connected to the guide frame. A pressure seat is slidably mounted on the lower end of the toothed column. A spring is provided between the pressure seat and the toothed column. The lower end of the spring is fixedly connected to the upper end of the pressure seat, and the upper end of the spring is fixedly connected to the lower end of the toothed column. A return spring is provided between the toothed column and the guide frame. The upper end of the return spring is fixedly connected to the upper part of the toothed column, and the lower end of the return spring is fixedly connected to the guide frame. Place the target product inside the guide frame, then press down on the toothed column. The toothed column acts downward on the spring, which in turn acts downward on the pressure seat, which in turn acts downward on the target. The toothed column is locked by the toothed pin, and the spring force continues to act on the pressure seat, so that the pressure seat continuously presses and fixes the target product, making it convenient and quick to press and fix the product.

[0008] Preferably, the guide frame includes a frame body, and a guide sleeve is fixedly connected to the upper part of the frame body. The guide sleeve is used to guide the tooth column to move up and down, and to guide the tooth pin to slide, so that the tooth pin can lock or unlock the tooth column.

[0009] Preferably, the guide frame further includes a leather block, which is fixedly connected to the lower part of the frame. The leather block increases the friction with the target product.

[0010] Preferably, the toothed column includes a pressing plate and a toothed column body. The lower end of the pressing plate is fixedly connected to the upper end of the toothed column body, and the toothed column body is slidably installed inside the guide sleeve. Pressing down on the pressing plate increases the contact area between the hand and the toothed column body, reduces the pressure, and directs the pressure downwards onto the toothed column body, thus improving operating comfort.

[0011] Preferably, the toothed column further includes a leather piece, which is fixedly connected to the upper part of the pressing plate. The leather piece increases the softness of the hand-pressed toothed column, further improving the comfort of operating it.

[0012] Preferably, the pressure seat includes a sliding column and a pressure plate. The lower end of the sliding column is fixedly connected to the upper end of the pressure plate. The sliding column is slidably inserted into the lower part of the toothed column. The spring is movably sleeved on the sliding column. The lower end of the spring is fixedly connected to the upper end of the guide frame, and the upper end of the spring is fixedly connected to the lower end of the toothed column. When the toothed column is locked by the toothed bolt, the spring force continues to act on the pressure plate and the target product, facilitating the pressing of the target product with the help of the spring force.

[0013] Preferably, the toothed bolt includes a toothed bolt body, which is slidably connected within the guide sleeve. The toothed bolt body engages with a toothed column. A connecting plate is symmetrically fixedly connected to the side of the toothed bolt body. The connecting plate is fixedly connected to one end of a tension spring, and the other end of the tension spring is fixedly connected to the guide sleeve. A pull button is fixedly connected to one side of the toothed bolt body. Pulling the pull button outwards acts on the toothed bolt body, causing it to overcome the spring force of the tension spring and disengage from the toothed column. Simultaneously operating both toothed bolts causes the toothed column to rise with the help of the return spring force, facilitating the release of the target product.

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

[0015] 1. Place the target product inside the guide frame, then press down on the toothed column. The toothed column acts downward on the spring, which in turn acts downward on the pressure seat, which in turn acts downward on the target. The toothed column is locked by the toothed pin, and the spring force continues to act on the pressure seat, so that the pressure seat continuously presses and fixes the target product, making it easy to quickly and easily press and fix the product.

[0016] 2. Press down on the pressure plate to increase the contact area between the hand and the pressure plate, reduce the pressure, and make the pressure act downward on the toothed column, thus improving the comfort of operation.

[0017] 3. After the toothed column is locked by the toothed bolt, the spring force continues to act on the pressure plate and the target product, making it convenient to press the target product with the help of the spring force.

[0018] 4. Pull the button outwards. The button acts on the toothed bolt, causing the toothed bolt to overcome the tension spring and detach from the toothed column. Simultaneously operate the two toothed bolts to make the toothed column rise with the help of the return spring, making it easier to release the target product. Attached Figure Description
