Description

Technical Field

[0001] This utility model relates to the field of welding fixtures, specifically a welding fixture for the frame of a car rear seat. Background Technology

[0002] The rear seats of a car consist of a frame, seat cushion, backrest, and adjustment mechanism. The frame supports and fixes the seat cushion and backrest. The frame is made of welded iron metal. Currently, when manually welding the rear seat frame of a car, the splicing parts are placed on a welding table, aligned, and pressed and fixed before welding. The fixing is done by applying pressure by hand. This fixing method is time-consuming and labor-intensive, cannot free up the hands for welding work, and the joints are not easy to press tightly, which is not conducive to achieving high-precision welding and assembly.

[0003] To address the aforementioned issues, we propose a welding fixture for the rear seat frame of automobiles, which improves upon the shortcomings of existing technologies. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a welding fixture for the rear seat frame of an automobile. In order to solve the above-mentioned technical problem, this utility model provides the following technical solution:

[0005] This utility model discloses a welding fixture for a rear seat frame of an automobile, comprising a welding table. A baffle and a vertical plate are fixed to both ends of the upper surface of the welding table. Two retractable guide rods are inserted into the vertical plate. An extrusion plate is fixedly connected to the inner end of each guide rod, and a spring is fitted onto the guide rod. An end plate is fixedly connected to the outer end of each guide rod, and a steel wire rope is fixedly connected to the end plate. Multiple lateral sliding supports are also provided on the extrusion plate. A retractable insertion plate is inserted into the other end of each support. A vertically movable pressure rod is inserted into the outer end of the insertion plate, and a pressure plate is fixed to the bottom end of the pressure rod. A hanging frame is fixed to the center of the bottom of one end of the welding table. A vertically movable foot pedal is provided on the hanging frame, and a second hanging frame is fixedly connected to the foot pedal. The other end of the steel wire rope passes through the welding table and is fixedly connected to the second hanging frame.

[0006] Preferably, a second spring is also fitted onto the pressure rod.

[0007] Preferably, a limiting groove is provided on the inner wall of one or both side plates of the hanging frame, and limiting blocks extending into the limiting groove are fixedly connected to both sides of the foot pedal.

[0008] Preferably, the upper surface of the extrusion plate is provided with a groove, and a sliding rod is fixedly connected between the inner walls of the two ends of the groove, and the bracket is slidably sleeved on the sliding rod.

[0009] Preferably, the bottom surface of the pressure plate is also fitted with a rubber pad.

[0010] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0011] By installing a retractable guide rod on the vertical plate, with a spring fitted on the guide rod and a pressing plate at the inner end of the guide rod, the spring's own elasticity pushes the pressing plate to press and fix the splice onto the welding table. The pressing plate is moved by a combination of a foot pedal and a steel wire rope, eliminating the need for manual pressing and fixing. Multiple sliding brackets are installed on the pressing plate, with retractable insertion plates on the brackets. The insertion plates are equipped with a combination of a pressure rod, a pressure plate, and a spring to press and fix the splice onto the welding table. This automotive rear seat frame welding fixture uses mechanization to replace manual fixing of splice parts, saving time and effort, freeing up hands, improving the tightness of the connection, and thus achieving high-precision welding assembly.

[0018] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention. Example

[0019] like Figure 1-4As shown, a welding fixture for a car rear seat frame includes a welding table 1. A baffle 2 and a vertical plate 3 are fixed to both ends of the upper surface of the welding table 1. Two retractable guide rods 4 are inserted into the vertical plate 3. A pressing plate 5 is fixedly connected to the inner end of each guide rod 4, and a spring 6 is also fitted onto the guide rod 4. An end plate 7 is fixedly connected to the outer end of each guide rod 4, and a steel wire rope 8 is fixedly connected to the end plate 7. Multiple brackets 9 that can slide laterally along the pressing plate 5 are also provided on the pressing plate 5, and a retractable connector plate is inserted into the other end of each bracket 9. 10. A pressure rod 11 that can be pulled up and down is inserted into the outer end of the plug plate 10. A pressure plate 12 is fixed to the bottom end of the pressure rod 11. A hanging frame 14 is also fixed at the center of the bottom of one end of the welding table 1. A foot pedal 15 that can be moved up and down is set on the hanging frame 14. A second hanging frame 16 is fixedly connected to the foot pedal 15. The other end of the steel wire rope 8 passes through the welding table 1 and is fixedly connected to the second hanging frame 16, forming an integral welding fixture structure for the rear seat frame of a car. It saves time and effort, frees up the hands, and improves the tightness of the connection.

[0020] In this embodiment, a second spring 13 is also sleeved on the pressure rod 11 for pressing down the pressure plate 12, and the pressure plate 12 is used to press the splice onto the welding table 1 from top to bottom.

[0021] In this embodiment, limit grooves 18 are provided on the inner walls of the two side plates of the hanging frame 14, and limit blocks 17 extending into the limit grooves 18 are fixedly connected to both sides of the foot pedal 15 to ensure that the foot pedal 15 can only slide up and down, avoid shaking, and improve stability.

[0022] In this embodiment, a groove 19 is provided on the upper surface of the extrusion plate 5, and a slide rod 20 is fixedly connected between the inner walls of both ends of the groove 19. The bracket 9 is slidably sleeved on the slide rod 20, which facilitates the adjustment of the pressing position of the pressure plate 12 and has strong flexibility and adjustability.

[0023] In this embodiment, a rubber pad is also adhered to the bottom surface of the pressure plate 12, which provides good protection and prevents damage to the splicing parts.

[0024] The principle and advantages of this utility model: When using this automotive rear seat frame welding fixture, first slide the bracket 9 to both ends of the extrusion plate 5, then pick up the splice, press down on the pedal 15 with your foot, pull the guide rod 4 outward, compress the spring 6, and increase the distance between the extrusion plate 5 and the baffle 2. Then place the splice on the welding table 1, aligning the joints of the splice. Then release the pedal 15, and the spring 6 uses its own elasticity to push the guide rod 4 inward, thereby firmly pressing and fixing the splice between the extrusion plate 5 and the baffle 2. Lift the pressure rod 11 to compress the second spring 13, increasing the distance between the pressure plate 12 and the welding table 1. Then slide the extrusion plate 5 to align the pressure plate 12 with the splice. Adjust the position of the pressure plate 12 by extending or shortening the insertion plate 10. Then release the pressure rod 11 and use the elastic force of the second spring 13 to press down the pressure plate 12. Use the pressure plate 12 to vertically press the splice. After pressing, welding can be carried out. Mechanization replaces manual fixing of the splice, saving time and effort, freeing up hands, improving the tightness of the connection, and thus achieving high-precision welding assembly.

[0025] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
