Description

Technical Field

[0001] This utility model relates to the field of automotive seat technology, and in particular to an automotive seat slide rail welding and fixing clamp. Background Technology

[0002] The angle of the seat needs to be adjusted in many situations, and this requires the use of car seat rails. Adjusting the seat angle in the driver's position is even more important, as the amount of legroom and movement space directly affects the driver's driving safety and comfort. Therefore, car seat rails play a significant role. Car seat rails mainly consist of several parts, including the left rail, the right rail, and the control lever. During the manufacturing process, support feet and lower support feet need to be welded onto the rails to facilitate their installation.

[0003] Before welding, a fixture is needed for positioning. However, existing fixtures typically involve clamping and positioning the slide rail first, then positioning and welding the lower support to the slide rail, and then positioning and welding the upper support to the slide rail in the same way. This process is cumbersome and prone to misalignment during welding, resulting in low welding efficiency and unreliable product quality. Therefore, it is necessary to propose a welding and fixing fixture for automotive seat slide rails to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a welding and fixing fixture for automotive seat slide rails, which has the advantages of high welding efficiency and better finished product quality.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a welding and fixing fixture for automotive seat slide rails, comprising a base plate, wherein a slide rail and a first positioning structure for fixing the slide rail are provided at the upper end of the base plate, a lower support leg and an upper support leg are provided at one end of the top of the slide rail, and a second positioning structure is provided at one end of the base plate near the lower support leg and the upper support leg to position it on the slide rail, the second positioning structure comprising two supports that stably support the end of the slide rail, a pneumatic clamp is fixedly installed between the two supports, a through square groove is provided between the slide rail, the lower support leg and the upper support leg, and a limiting insert that abuts against the square groove is fixedly installed on each of the two jaws of the pneumatic clamp.

[0006] By adopting the above technical solution, the slide rail is placed on the support and positioned by the first positioning structure. Then, the lower support and the upper support are placed at the end of the slide rail. After adjusting the position, the distance between the two limiting inserts is controlled by the pneumatic clamp to make them clamp with the square groove, thereby fixing the lower support and the upper support at the welding position of the slide rail at the same time. This allows the workers to weld the lower support and the upper support to the slide rail in one step, reducing the number of processes, reducing costs and increasing efficiency, and achieving higher welding accuracy.

[0007] A further feature of this invention is that the base plate is also provided with a pressing component that simultaneously presses the slide rail, the lower support leg, and the upper support leg together. The pressing component includes a first fixing plate fixed to the top of the base plate. A connecting plate is fixed to the first fixing plate. A movable plate and a manual quick clamp for pushing the movable plate down are provided at the upper end of the connecting plate. Two first pressure rods that are tightly pressed against the upper end of the upper support leg are fixed to the bottom of the movable plate.

[0008] By adopting the above technical solution, the moving plate is pressed down and fixed by the manual quick clamp, which drives the first pressure rod to move down. With the cooperation of the support, its lower end presses the upper support foot tightly, thereby improving the stability of clamping the upper support foot.

[0009] A further feature of this invention is that the top of the base plate is fixedly fitted with a lower support foot insert located on the rear side of the support, and the bottom of the movable plate is fixedly fitted with two second pressure rods that are tightly fitted to the upper end of the lower support foot.

[0010] By adopting the above technical solution, while the moving plate moves down, the second pressure rod is pushed down, and the lower support foot can be further positioned through the lower support foot insert, making the clamping more stable.

[0011] A further feature of this invention is that the first positioning structure includes two second fixing plates fixedly mounted on the top of the base plate, each of the two second fixing plates being equipped with a manual quick clamp, and the top of the base plate is also fixedly equipped with multiple columns for supporting the slide rail.

[0012] By adopting the above technical solution, the slide rail is placed on the column and its position is adjusted, and then it is quickly clamped and fixed by manual quick clamp.

[0013] A further feature of this invention is that the manual quick clamp includes a mounting plate, on which a pressing handle and a push rod are provided, a connecting piece is hinged between the pressing handle and the push rod, and a guide block that is slidably adapted to the push rod is fixedly mounted on the mounting plate.

[0014] By adopting the above technical solution, hold the push-down handle and lift it up. The push rod will move up through the connecting part. After placing the workpiece to be welded, push the handle down to quickly fix the workpiece.

[0015] The beneficial effects of this utility model are:

[0016] 1. In this utility model, the slide rail is placed on the support and positioned by the first positioning structure. Then, the lower support leg and the upper support leg are placed at the end of the slide rail. After the position is adjusted, the distance between the two limiting inserts is controlled by the pneumatic clamp so that they are clamped with the square groove. Thus, the lower support leg and the upper support leg are fixed at the welding position of the slide rail at the same time. This allows the workers to weld the lower support leg and the upper support leg to the slide rail in one step, reducing the number of processes, reducing costs and increasing efficiency, and achieving higher welding accuracy.

[0017] 2. In this utility model, the movable plate is pressed down and fixed by a manual quick clamp, which drives the first pressure rod and the second pressure rod to move down. With the cooperation of the support and the lower support foot support insert, the lower end of the rod presses the upper support foot and the lower support foot together, which improves the stability of the support foot clamping and prevents misalignment during subsequent welding.
