Description

Technical Field

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

[0002] A spring is a mechanical part that uses elasticity to work. A part made of elastic material deforms under the action of an external force and returns to its original state after the external force is removed. It is generally made of spring steel. A very important step in the production process of a spring is grinding. The surface of an unground spring has burrs and is not smooth and flat enough, which will pose a safety hazard during use. The structures of current grinding devices are generally the same. Basically, they all drive a grinding disc through a driving mechanism and can barely meet the use requirements.

[0003] The prior art such as the Chinese patent with the publication number of CN210160893U discloses a spring processing and grinding device, including a base.

The anti-disengagement block 420 is provided to prevent the bidirectional threaded rod 415 from disengaging from the support leg 2.

[0035] Specifically, twenty-four groups of second chutes 505 are provided on the surface of the second rotating disk 410.

[0038] The effects achieved by the above components are as follows: The rotation of the screw rod 501 causes the disc 510 to make a vertical displacement. As the disc 510 moves downward, the tapered column 512 also moves downward and applies an outward thrust to the clamping column 506, thereby causing the clamping column 506 to move outward. The telescopic sleeve is provided to prevent the disc 510 from rotating with the screw rod 501.

[0039] Working principle: By setting the grinding mechanism 4, first rotate the first rotary valve 416 to drive the rotation of the bidirectional threaded rod 415, and then drive the moving block 417 to move horizontally. The moving blocks 417 moving towards each other drive the grinding brush plate 418 to approach the middle through the first chute 419 until the grinding brush plate 418 contacts the spring. Subsequently, start the motor 402 to make the driving bevel gear 403 rotate, and then drive the driven bevel gear 404 to rotate. The two make both the first rotating disc 406 and the second rotating disc 410 start to rotate. The rotation of the first rotating disc 406 drives the rotation of the entire six groups of springs, and the rotation of the second rotating disc 410 drives the self-rotation of a single spring. By setting the grinding mechanism 4, the six groups of springs can be ground independently at the same time, and the two methods of the six groups of springs revolving and a single spring rotating can make all surfaces of the spring quickly receive grinding, effectively improving the usability of the spring processing and grinding device. In addition, by setting the clamping mechanism 5, first sleeved the springs on the six groups of clamping columns 506 respectively, then put the protective cover 422 into the annular groove 421, and then rotate the second rotary valve 504 to make the screw rod 501 rotate accordingly, so that the disc 510 makes a vertical downward displacement. The tapered column 512 on the disc 510 contacts the clamping column 506 during the downward movement, and continuously applies an outward thrust as it continues to move downward, thereby causing the clamping column 506 to slide outward in the second chute 505 until the spring is completely tightened, achieving the effect of stably clamping the spring. By setting the clamping mechanism 5, for springs of different sizes, only need to rotate the rotary valve to a certain position to stably clamp the six groups of springs at the same time, and prevent the springs from moving during the grinding process, effectively improving the stability of the spring processing and grinding device.
