Detailed Description

The present invention is further described below in conjunction with the following figures and specific examples so that those skilled in the art may better understand the present invention and practice it, but the examples are not intended to limit the present invention.

Referring to fig. 1 to 5, the present invention discloses a magnetic chuck including a chuck body 10, an adjusting member 40 and an adsorption assembly. The disk body 10 is provided with a plurality of guide grooves 11 along the radial direction, and the guide grooves 11 are uniformly distributed around the center of the disk body 10. The central axis of the adjusting member 40 coincides with the central axis of the tray body 10, the adjusting member 40 is provided with a plurality of curved track grooves 41, and the plurality of track grooves 41 are uniformly distributed around the center of the adjusting member 40. The distance of the single track groove 41 from the center of the adjusting member 40 decreases in the track direction thereof, and the number of track grooves 41 is the same as the number of guide grooves 11. The adsorption component comprises a plurality of connecting rods 30, the connecting rods 30 are arranged in one-to-one correspondence with the guide grooves 11, the connecting rods 30 penetrate through the track grooves 41 and the guide grooves 11, and each connecting rod 30 is provided with an adsorption piece 20. The adjusting member 40 rotates to achieve simultaneous inward contraction or simultaneous outward movement of the plurality of suction members 20. After the adjusting part is adjusted in a rotating mode, the adjusting part can be fixed with the disc body, large bolts can be arranged for fixing the adjusting part and the disc body, the bolts penetrate through the adjusting part, the bolts are matched with the central threads of the disc, and therefore the adjusting part can be fixed with the disc body. Since the adjusting member 40 is provided with a plurality of track grooves which are uniformly distributed around the adjusting member 40, when the adjusting member 40 is rotated, the plurality of connecting rods 30 move synchronously, so that the plurality of adsorbing members 20 contract or expand synchronously, and the plurality of adsorbing members 20 can be on a circular track. Therefore, the magnetic sucker can adsorb workpieces with different sizes, and has the advantages of wide application range, good stability and balanced stress.

In the present invention, the adsorbing member 20 is an electromagnet. The electromagnet can adsorb ferromagnetic materials, has high adsorption strength, and is convenient for controlling the magnetic strength and the magnetic on-off.

Referring to fig. 3 and 4, the adsorption assembly further includes a spring 32 and a pin 31, one end of the pin 31 is slidably connected to the connection rod 30, the other end of the pin 31 is fixed to the adsorption member 20, and the spring 32 is sleeved on the pin 31. Because spring 32 cover is established on pin 31, but spring 32 one end butt regulating part 40, other end butt absorption piece 20, so, when this magnetic chuck adsorbs the work piece, can have better elastic buffer performance, prevent that magnetic chuck from damaging the product in adsorbing the excessive collision of product in-process. Because the electro-magnet has very strong magnetism, in the synchronous absorption product in-process of a plurality of adsorption heads, because the absorption piece 20 can follow the activity of spring 32 direction, also avoid the excessive collision that can product surface unevenness leads to, the requirement to the product is low, is convenient for adsorb different products.
