Description

Technical Field

[0001] This utility model relates to the field of automobile manufacturing technology, and in particular to a welding fixture for automobile seat side panel frame. Background Technology

[0002] Car seat side panels are important interior components. Their frames are usually welded from metal tubing and reinforcing sheet metal parts. In the welding production process, in order to ensure the dimensional accuracy and welding quality of the assembly, special welding fixtures are required to accurately position and reliably clamp multiple parts to be welded.

[0003] Currently, traditional clamp designs often employ a one-cylinder-one-press mode, meaning that each clamping point is equipped with a separate drive cylinder.

[0004] The aforementioned existing technical solutions have the following drawbacks: although they are functionally reliable, they directly lead to complex fixture structures and high manufacturing costs. Utility Model Content

[0005] The purpose of this invention is to provide a welding fixture for the side panel frame of an automotive seat to solve the problems existing in the prior art.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A welding fixture for a car seat side panel frame includes a fixing plate. Three first pads are disposed on the top of the fixing plate. A first support block, a second support block, and a cylinder are respectively disposed on the top of the three first pads. The cylinder includes a body and a telescopic rod. The body is used to move the telescopic rod up and down. The telescopic rod is located at the inner top of the body. A pressure block is movably connected to the top of the telescopic rod. Positioning blocks are fixedly installed on the tops of both the first and second support blocks. A positioning groove is disposed at the middle of the top of each positioning block. The opposite ends of the positioning groove are completely open. The positioning groove is used to position the end of a workpiece. The pressure block is used to press the workpiece tightly inside the positioning groove under the action of the telescopic rod of the cylinder.

[0007] By adopting the above technical solution, the structure of the pressure block allows the frame and sheet metal parts that make up the seat side panel to be pressed simultaneously into the positioning groove under the drive of the cylinder. This enables a single drive structure to press multiple parts, reducing the number of drive structures and greatly saving manufacturing costs.

[0008] In a further embodiment, the pressure block is composed of an integrally formed first straight edge, a second straight edge, and a third straight edge. The first straight edge is located at one end of the second straight edge, and the third straight edge is located in the middle section of the second straight edge. The ends of the first straight edge and the third straight edge that are not connected to the second straight edge are opposite to each other. The end of the third straight edge that is not connected to the second straight edge is movably connected to the telescopic rod of the cylinder. A third support block is fixedly installed on the top of the cylinder body. The top of the third support block is provided with a horizontal circular hole, and both ends of the circular hole penetrate the third support block. A circular rod is rotatably installed in the circular hole. Both ends of the circular rod are provided with extension ends located outside the circular hole. A metal sheet is rotatably installed on the extension ends of the circular rod. A horizontal through hole is provided in the middle section of the third straight edge. A rotating shaft is rotatably installed in the through hole. Both ends of the rotating shaft are provided with extension ends located outside the through hole. The extension ends of the rotating shaft are movably connected to a metal sheet.

[0009] By adopting the above technical solution, when the cylinder's telescopic rod moves up and down, it will drive one end of the third straight edge to move up and down. The third straight edge rotates around the axis of the rotating shaft. However, since the cylinder's telescopic rod can only move up and down, it is necessary to use a thin metal sheet to achieve changes in horizontal displacement so as not to interfere with the overall rotation of the entire pressure block.

[0010] In a further embodiment, annular grooves are provided on both the extended end of the rotating shaft and the extended section of the round rod.

[0011] By adopting the above technical solution, the two ends of the rotating shaft and the round rod can be locked by a snap ring, thus preventing the rotating shaft and the round rod from coming out of their respective holes.

[0012] In a further embodiment, the positioning block includes a block and a plate, a second pad is provided between the block and the plate, at least three positioning holes are provided at equal intervals from top to bottom on one side of the block, and one end of the positioning hole passes through the second pad and the block, and the tops of the block and the plate are close to each other to form a positioning groove.

[0013] By adopting the above technical solution, a bolt is inserted into the middle positioning hole, and then threads are set in the corresponding positioning holes on the block to achieve a fixed connection between the plate and the block. Then, positioning pins are inserted into the remaining positioning holes to achieve the positioning of the plate and the block. Because the components that need to be positioned in the positioning groove are different, in order to reduce the adjustment and adaptation of the structure of this device and make this device adaptable to the welding of more models of seat frames, the positioning blocks are disassembled to achieve quick replacement.

[0014] In a further embodiment, a height-equalizing frame is fixedly installed at the bottom of the fixing plate. The height-equalizing frame consists of a rectangular frame and multiple height-equalizing sleeves. The multiple height-equalizing sleeves are evenly arranged circumferentially on the top of the rectangular frame. The top of the height-equalizing sleeves is fixedly connected to the fixing plate, and the bottom of the height-equalizing sleeves is fixedly connected to the rectangular frame.

[0015] In summary, this utility model has the following beneficial effects: 1. The structure of the pressure block allows the frame and sheet metal parts that make up the seat side panel to be pressed simultaneously into the positioning groove under the drive of the cylinder. This enables a single drive structure to press multiple parts, reducing the number of drive structures and greatly saving manufacturing costs. Attached Figure Description
