Description

Technical Field

[0001] The utility model relates to the technical field of spring processing, in particular to a spring end grinding device. Background Art

[0002] With the continuous development of the manufacturing industry and advancements in technology, the demand for precision parts is increasing. Springs, as a common elastic component, are widely used in the automotive, aerospace, mechanical equipment and other fields. To ensure the quality and performance of springs, proper polishing of their ends is particularly important.

[0003] Existing spring end grinding technologies primarily include manual grinding and simple power tool-assisted grinding. While manual grinding allows for flexible adjustment of force and angle, it requires significant manpower and results in low efficiency. While power grinding equipment can save manpower to a certain extent, most existing power grinding equipment can only grind one end of the spring at a time, and cannot simultaneously grind both ends. Consequently, each end must be polished sequentially, resulting in low efficiency. Utility Model Content

Then, the stepper motor can be started to drive the bearing platform to rotate, so that the bearing platform drives the spring to be ground to a position close to the grinding mechanism for grinding. Through the setting of the grinding mechanism, when the bearing platform drives the spring to be ground to move between the two grinding wheels, the second rotating motor is started to drive the grinding wheel to rotate, and at the same time, the first rotating motor is started to drive the bidirectional screw to rotate, so that the bidirectional screw drives the two support arms to approach each other, and the support arms drive the grinding wheel close to the spring. The two grinding wheels grind both ends of the spring at the same time, thereby improving work efficiency.

After grinding is completed, the dual-axis motor can be started to drive the one-way screw to rotate in the opposite direction, so that the two arc-shaped splints are separated and the spring can fall.

[0013] Optionally, rubber pads are fixedly connected to the sides of the two arc-shaped clamping plates that are close to each other.

[0014] By adopting the above technical solution and providing the rubber pad, it is possible to avoid damage to the spring caused by the arc-shaped clamping plate clamping the spring.

A clamping mechanism 24 is provided in each bearing groove 23. Through the setting of the bearing assembly 2, when the spring is polished, the spring to be polished can be placed vertically in the bearing groove 23 away from the polishing mechanism 3, and the clamping mechanism 24 can be used to clamp the spring. Then, the stepper motor can be started to drive the bearing platform 22 to rotate, so that the bearing platform 22 drives the spring to be polished to move to a position close to the polishing mechanism 3 for polishing.

[0034] Specifically, the clamping mechanism 24 includes two symmetrically arranged arc-shaped clamping plates 241, and a U-shaped groove is opened on one side of each bearing groove 23 inside the support seat 21.

The one-way screw 243 is horizontally arranged. An L-shaped connecting rod 244 is threadedly connected to the one-way screw 243. One end of the L-shaped connecting rod 244 is fixedly connected to the arc-shaped clamping plate 241. Through the clamping mechanism 24, place the spring between the two arc-shaped splints 241, start the dual-axis motor 242 to drive the two one-way screws 243 to rotate, so that the one-way screws 243 drive the two L-shaped connecting rods 244 to approach each other, and the L-shaped connecting rods 244 drive the two arc-shaped splints 241 to approach each other, thereby clamping and fixing the spring. After the grinding is completed, the dual-axis motor 242 can be started to drive the one-way screw 243 to rotate in the opposite direction, so that the two arc-shaped splints 241 are separated, so that the spring can fall.

[0035] Among them, the two arc-shaped clamping plates 241 are fixedly connected to the side close to each other with a rubber pad 245.

The dual-axis motor 242 is started to drive the two one-way screws 243 to rotate, so that the one-way screws 243 drive the two L-shaped connecting rods 244 to approach each other, and the L-shaped connecting rods 244 drive the two arc-shaped clamping plates 241 to approach each other, thereby clamping and fixing the spring. Then, the stepping motor can be started to drive the bearing platform 22 to rotate, so that the bearing platform 22 drives the spring to be ground to a position close to the grinding mechanism 3 for grinding. When the bearing platform 22 drives the spring to be ground When the spring moves between the two grinding wheels 36, the second rotary motor 35 is started to drive the grinding wheel 36 to rotate, and at the same time, the first rotary motor 32 is started to drive the bidirectional screw 33 to rotate, so that the bidirectional screw 33 drives the two support arms 34 to approach each other, and the support arms 34 drives the grinding wheel 36 to approach the spring. The two grinding wheels 36 grind both ends of the spring at the same time. When the polished spring passes over the collection bucket 13, the clamping mechanism 24 will release the spring, so that the spring automatically falls into the collection bucket 13 for collection. In addition, during polishing, the vacuum cleaner 39 can be started to suck the dust generated during the polishing process into the dust suction pipe 310 to reduce the pollution of dust to the environment.
