The technical effect of the present application scheme is that it is easy to press springs of different diameters together.

[0006] The present application can be implemented through the following technical solutions: A spring compression machine, including an adjustment rod, a first electric push rod, a moving block, a second electric push rod, a placement plate and a third electric push rod. The adjustment rod is placed vertically and several are configured. Several adjustment rods are used to sleeve the same spring. Several adjustment rods are evenly distributed around the spring and can contact the axial inner wall of the same spring; the first electric push rod is used to drive the adjustment rod to move horizontally and linearly to approach or move away from the axis of the spring; the moving blocks are configured in several and are distributed along the circumference of the spring, and the lower surfaces of several moving blocks can contact the upper surface of the spring; the second electric push rod is used to drive the moving block to approach or move away from the axis of the spring; the placement plate is provided with a hole through which the axis of the hole coincides with the axis of the spring, and the fixed part of the second electric push rod is fixedly connected to the placement plate; the third electric push rod is used to drive the placement plate to move linearly in the vertical direction, so that the moving block can compress the spring as the placement plate moves in the vertical direction.

[0013] In the above technical solution, by making the roller rollingly connected to the upper surface of the support frame, the telescopic end of the first electric push rod can be prevented from wearing when contacting the upper surface of the support frame, thereby extending the service life of the first electric push rod.

[0014] Furthermore, there are a plurality of rollers, and the axes of the plurality of rollers are parallel to each other.

[0015] In the above technical solution, by configuring a plurality of rollers, the plurality of rollers can simultaneously support the telescopic end of the first electric push rod, and the supporting effect is better.

[0021] In the above technical solution, the fixed end of the third electric push rod is detachably connected to the frame, and the frame is fixedly connected to the support frame. When the support frame is moved, it can be moved together with the placement plate. After moving the support frame, there is no need to align the axis of the hole and the spring, which is more convenient.

[0022] To sum up, the present application has the following technical effects: when it is necessary to compress springs with different diameters, the first electric push rod can be turned on to change the position of the adjusting rod so that the outer walls of the multiple adjusting rods in the length direction can contact the axial inner wall of the spring, and then the second electric push rod can be turned on to adjust the position of the moving block so that the moving block abuts against the upper surface of the spring, and then the third electric push rod is used to drive the placement plate to move vertically downward, and the moving block can compress the spring.

The outer walls of the three adjusting rods 1 in the length direction can contact the axial inner wall of the same spring 2, and the first electric push rod 3 is used to drive the adjusting rod 1 to approach or move away from the axis of the spring 2 along the radial direction of the spring 2, so that the three adjusting rods 1 can be sleeved with springs 2 with different diameters. A frame 13 is placed beside the three adjusting rods 1, and two third electric push rods 7 are detachably installed on the frame 13. The two third electric push rods 7 are used to drive the same placement plate 6 to move in the vertical direction. The placement plate 6 has a hole 61 extending through it, and the axis of the hole 61 coincides with the axis of the spring 2. Three moving blocks 4 are placed beside the hole 61. The three moving blocks 4 are arranged along the circumference of the spring 2 and the lower surfaces can contact the upper surface of the spring 2. The three moving blocks 4 are driven by a second electric push rod 5 to move linearly in the radial direction of the spring 2, so that the moving blocks 4 can approach or move away from the axis of the spring 2, and then the three moving blocks 4 can abut against the upper surfaces of springs 2 of different diameters. The fixed end of the second electric push rod 5 is detachably connected to the placement plate 6. During the downward movement of the placement plate 6 in the vertical direction, the moving blocks 4 can move downward together with the placement plate 6 to press the spring 2.

The two displacement sensors 8 can detect the moving distance of the adjusting rod 1 and the moving block 4 one by one. The first electric push rod 3 and the second electric push rod 5 are electrically connected to a controller 9. The six displacement sensors 8 are electrically connected to the six controllers 9 one by one. When the moving distance of the moving block 4 or the adjusting rod 1 reaches a preset value, the controller 9 can control the first electric push rod 3 or the second electric push rod 5 electrically connected to itself to stop extending or retracting, which is more convenient. Among them, a fixing sleeve 14 can be detachably installed at the bottom of each adjusting rod 1. The fixing sleeve 14 coincides with the axis of the adjusting rod 1. The lower surface of the spring 2 can be abutted against the upper surface of the fixing sleeve 14. The fixing sleeve 14 has a placement groove 141 along its own axial direction.
