Description

Technical Field

[0001] This utility model relates to the field of automotive repair equipment technology, and in particular to a convenient car spring removal and installation machine. Background Technology

[0002] In the field of modern automotive repair and maintenance, the disassembly and installation of car springs is a crucial and frequent operation. With the rapid development of the automotive industry, the models and styles of cars are becoming increasingly diverse, and their chassis structures, as well as the installation methods and specifications of springs, are also showing diversified characteristics. When disassembling and installing existing car springs, it is necessary to rely on some tool combinations that are not very versatile and are inconvenient to operate. The spring is first clamped to control its contraction before one end of the car shock absorber can be disassembled and the spring removed. However, the elastic potential energy stored in the spring may be suddenly released, and the car shock absorber as a whole is not fixed at this time. The car shock absorber as a whole will move, and the existing simple tool combinations are difficult to deal with effectively. This can easily cause serious personal injury to the operator.

Specifically, by setting the disassembly and assembly slot 101 into a "U" shape and fixing the drain pipe 102 to the front of the "U" shape, oil and dust can be collected when disassembling and assembling the springs on the car shock absorber. The "U" shape structure improves the ease of cleaning the disassembly and assembly slot 101, and the drain pipe 102 guides the oil and prevents the oil from staining the ground.

[0026] The disassembly / assembly groove 101 has U-shaped guide grooves 10101 in the middle of the left and right inner walls. The front and rear ends of the bidirectional screw 2 are rotatably connected to the front and rear side walls of the guide grooves 10101.

The telescopic front end of the electric cylinder 5 is fixedly connected to the outer wall of the rear side wall of the disassembly and assembly slot 101. Specifically, by connecting the telescopic front end of the electric cylinder 5 to the outer wall of the rear side wall of the disassembly and assembly slot 101, the distance between the U-shaped slider at the bottom rear side of the sliding bracket 4 and the rear side wall of the disassembly and assembly slot 101 can be changed, thereby adjusting the position of the sliding bracket 4 in the disassembly and assembly slot 101. This allows for adjustment according to the length of the car shock absorber, fixing one end of the car shock absorber to the fixing rod 401, thereby fixing the car shock absorber and improving the stability during the disassembly of the shock absorber spring, thus improving the efficiency of spring disassembly.

In 703, a rotating block 802 is fixedly connected to the end of the connecting rod 801. The rotating block 802 is slidably connected in the rotating groove 701 opened in the sliding guide block 7. Specifically, the motor 3 drives the connected bidirectional screw 2 to rotate. The bidirectional screw 2 is simultaneously connected to the synchronous pulley 201 through the synchronous belt 6, so that the two bidirectional screws 2 rotate at the same time, thereby adjusting the distance between the two sliding guide blocks 7 slidably connected on the left and right side walls of the disassembly and assembly groove 101. This facilitates the fixing and tightening of the car spring by the spring clip 8 connected on the sliding guide block 7, increasing the convenience of operation. This makes it easier to remove the car spring when disassembling the car shock absorber. Furthermore, the spring clip 8 is connected to the sliding guide block 7 through the connecting rod 801 and the rotating block 802, so that the spring clip 8 can rotate to adjust the connection angle of the spring clip 8 according to different springs.

The "U" shape structure improves the ease of cleaning the removal and installation slot 101, and the drain pipe 102 drains the oil. The electric cylinder 5 is connected to the rear side wall of the removal and installation slot 101 by extending its front end. The distance between the U-shaped slider at the bottom rear of the sliding bracket 4 and the rear side wall of the removal and installation slot 101 can be changed by the electric cylinder 5, thereby adjusting the position of the sliding bracket 4 in the removal and installation slot 101 to adjust according to the length of the car shock absorber. One end of the car shock absorber is fixed to the fixing rod 401. The upper part of the motor drives the connected bidirectional screw 2 to rotate, thereby fixing the car shock absorber and improving the stability when disassembling the shock absorber spring. The bidirectional screw 2 is driven by the motor 3 to rotate. The bidirectional screw 2 is simultaneously connected to the synchronous pulley 201 through the synchronous belt 6, so that the two bidirectional screw 2 rotate at the same time. This adjusts the distance between the two sliding guide blocks 7 that are slidably connected on the left and right side walls of the disassembly and assembly slot 101. This facilitates the fixing and tightening of the car spring by the spring clamp block 8 connected on the sliding guide block 7, thereby disassembling the car shock absorber and facilitating the removal of the car spring. The spring clamp block 8 is connected to the sliding guide block 7 through the connecting rod 801 and the rotating block 802, so that the spring clamp block 8 can rotate to adjust the connection angle of the spring clamp block 8 according to different springs.
