Description

Technical Field

[0001] The utility model relates to the technical field of automobile seat frame welding, in particular to a welding fixture. Background Art

[0002] The car seat frame is the most basic component structure of the car seat. The seat frame is usually processed and fixed by welding. The car seat frame needs to be fixed in position during welding. The car seat welding fixture is a fixture used during welding in the production process of car seats, which can prevent the seat frame from shaking during the welding process.

[0003] In the prior art, it is often necessary to adjust the installation positions of multiple clamps according to the size of the seat frame, and the clamps are generally fastened to the mounting holes on the clamp table by multiple bolts. Therefore, each time the installation position of the clamp is adjusted, multiple bolts need to be turned, which is time-consuming, labor-intensive, inefficient, and has a high labor intensity for the staff. Therefore, we have introduced a welding clamp. Utility Model Content

[0004] The purpose of the utility model is to provide a welding fixture, which is convenient for quickly installing and removing the fixture from the fixture table, saving time and labor, and has high efficiency, reducing the labor intensity of the staff, so as to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] The top end of the fixing plate is provided with a fixing plate, and the fixing plate has a fixing portion which is fixedly provided with a fixing plate on the bottom end of the fixing plate.

[0007] Preferably, the unlocking mechanism includes a movable block, which is slidably arranged on the inner lower side of the rectangular groove, a V-shaped groove is provided at the upper end of the movable block, a push rod is fixedly provided on the side where the lower ends of the two locking blocks are close to each other, and a through hole is provided on the lower side of the rectangular groove.

[0008] Preferably, rollers are fixedly provided at the lower ends of the two push rods.

[0009] Preferably, a slope is provided on the lower side of one end of the locking block outside the sliding hole.

[0010] Preferably, an arc-shaped groove is provided at the upper end of the placement seat.

[0011] Preferably, a push block is slidably provided in the through hole, the upper end of the push block is fixedly connected to the movable block, and the lower end of the push block extends to the outside of the mounting rod.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The welding fixture is provided with a mounting rod, a spring, a locking block, a push rod, a push block and a movable block. When installing the fixture, the mounting rod at the bottom of the mounting plate is inserted into the corresponding mounting hole according to the size of the seat. The mounting hole drives the locking block to move into the sliding hole through the inclined surface and squeezes the spring. When the locking block moves to the bottom of the fixture table, the spring pushes the two locking blocks to engage with the bottom of the fixture table. When the fixture needs to be removed, the push block is pushed upward, and the push block drives the movable block to move upward. The push rod drives the two locking blocks to move into the sliding hole through the V-groove. At this time, the fixture can be removed from the fixture table, which is convenient for quickly installing and removing the fixture from the fixture table, saving time and effort, with high efficiency, and reducing the labor intensity of the staff.

[0019] See also Figures 1 to 3 , the utility model provides a technical solution:

[0020] A welding fixture comprises a fixture table 2, and a plurality of mounting plates 1 are provided at the upper end of the fixture table 2. Cylinders 5 and placement seats 3 are fixedly provided on both sides of the upper ends of the plurality of mounting plates 1. The piston rod ends of the cylinders 5 are fixedly connected with clamping plates 4. One end of the clamping plates 4 extends to the upper part of the placement seat 3. Mounting rods 6 are fixedly provided on both sides of the bottom of the mounting plate 1. A plurality of mounting holes matching the mounting rods 6 are evenly provided at the upper end of the fixture table 2. The lower ends of the mounting rods 6 pass through the mounting holes and extend to the lower part of the fixture table 2. A sliding hole is provided at the rod wall of the mounting rod 6 at the lower side of the fixture table 2. A rectangular groove is provided at the lower side of the sliding hole inside the mounting rod 6. Locking blocks 8 are slidably provided on both sides of the inner part of the sliding hole. The opposite ends of the two locking blocks 8 extend out of the sliding hole and are clamped with the bottom of the fixture table 2. A spring 7 is fixed between the two locking blocks 8, and an unlocking mechanism is provided in the rectangular groove.

[0021] The unlocking mechanism includes a movable block 11, which is slidably arranged at the lower side of the inner rectangular groove. A V-shaped groove is provided at the upper end of the movable block 11. A push rod 9 is fixedly provided on the side close to the lower ends of the two locking blocks 8, and a through hole is provided on the lower side of the rectangular groove.

[0022] Rollers 12 are fixedly provided at the lower ends of the two push rods 9 , and the rollers 12 reduce the friction between the push rods 9 and the V-shaped grooves.

[0023] The lower side of one end of the locking block 8 outside the sliding hole is provided with an inclined surface, which facilitates the locking block 8 to enter the installation hole.

[0024] An arc groove is formed at the upper end of the placement seat 3, and the arc groove can facilitate the positioning of the seat frame.
