Problems solved by technology
[0002] At present, some front suspensions that rely on springs for shock absorption often have the situation that the cab is skewed due to the difference in the compression of the left and right springs during the assembly process, and the opening size of the suspension is difficult to control due to the flexible deformation of the springs, and the mounting surfaces on both sides are often flared. Shape or parallelogram shape, which caused great trouble to the assembly of the suspension and cab
In addition, the method of compressing the spring in the early stage is mainly to squeeze the spring manually with a crowbar. It is estimated that the spring needs to be manually compressed with a 1.5-meter crowbar to reach the specified compression amount, and it must be held until the springs on both sides are fixed before it can be released. Time-consuming and labor-intensive, and there are great security risks

Embodiment Construction
[0014] In order to further describe the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0015] figure 1 and 2 A spring pressing device shown includes a frame 3, and the upper, middle and lower parts of the frame 3 are sequentially provided with a cylinder 9, a horizontal operating table 1, and a PLC control box 8, and the horizontal operating table 1 is arranged with two parallel The assembly table 4 is arranged, the top plane of the assembly table 4 is provided with several fixed pins 2, and the opposite sides of the two assembly tables 4 are provided with positioning holes 10; the cylinder 9 is directly above the horizontal operation table 1 through the cylinder plunger 7 The pressure plate 6 is connected; the bottom of the workpiece is assembled on the assembly table 4, and the PLC control box 8 controls the operation of the cylinder 9 to make the pressure plate 6 press the ...

The invention relates to the technical field of automobile parts processing, in particular to a spring compressor. A cylinder, a horizontal operating table and a PLC control box are arranged sequentially on the upper, middle and lower portions of a frame, two parallelly arranged assembly tables are disposed on the horizontal operating table, a plurality of fixing pins are arranged on the top plane of the assembly table, and opposite sides of the two assembly tables are provided with positioning holes; the cylinder is connected with a compressing plate right above the horizontal operating table through a cylinder plunger; the bottom of a workpiece is fitted above the assembly tables, the PLC control box controls the cylinder to operate, enabling the compressing plate to compress the top of the workpiece. Opening size of a connecting plate is fixed before assembly, thus preventing workpiece distortion and overproof opening size due to spring compressing deformation from affecting the installation of the workpiece and a cab. As the cylinder transmits force evenly to left and right through a rigid element, compressions of the springs on two sides are substantially equal, preventing cab skew due to a bigger difference between the compressions of the springs on two sides.
