Description

Technical Field

[0001] The utility model relates to the technical field of spring preloading, in particular to a spring preloading machine. Background Art

[0002] A spring is a mechanical part that uses elasticity to work, including tension springs, compression springs, torsion springs, etc. As for compression springs, they need to be pre-stressed after production to pre-stress the spring to a set length. This process requires the use of a pre-stressing machine.

[0003] The utility model patent application document with publication number "CN218855505U" discloses a spring pre-pressing machine, including a workbench, a support column is fixed on the workbench table top, a mounting plate is fixed on the top of the support column, a cylinder is installed on the surface of the mounting plate, a fixing plate is fixed on the output end of the cylinder, a connecting plate is fixed on the bottom of the fixing plate, a pressing rod is fixed on the bottom of the connecting plate, a base is placed on the workbench table top, a positioning rod is fixed on the surface of the base, a spring is sleeved on the surface of the positioning rod, and a pressure plate is slidably connected to the surface of the positioning rod, the spring is arranged between the pressure plate and the base, and the top of the pressure plate is against the bottom of the pressing rod, by respectively sleeveing ​​multiple springs of different models on the surfaces of multiple positioning rods and under the action of the cylinder, the purpose of pre-pressing multiple springs of different models can be achieved at the same time, effectively improving the pre-pressing efficiency of the spring, and being able to pre-press different models of springs, reducing the pre-pressing cost of the spring.

[0004] The spring preloading machine disclosed in the above document has the following defects: when using this technical solution, it is not convenient to take out a large number of springs at one time after pressing the first batch of springs, which wastes a lot of time, and it is impossible to put the springs in advance after pressing the first batch of springs. Only after taking out the springs on the column can a batch of springs be put down, resulting in a work idle period and relatively low work efficiency.

[0005] It can be seen from this that the existing spring preloading machine does not have a good preloading structure, and it is necessary to improve the existing deficiencies and provide a spring preloading machine. Utility Model Content
