Specific embodiment

It as shown in Figures 1 to 5, is a kind of sheet part the processing vacuum chuck, including vacuum pipe 1 of the utility model And the sucker 2 of 1 end of vacuum pipe is set, vacuum pipe 1 is equipped with a chassis 3, and chassis 3 is equipped with slidable limit The outside of plate 4, sucker 2 is equipped with elastic ring 5, and spring 6 is equipped between the inner wall and sucker of elastic ring 5, and spring 6 is hollow structure, One end of spring 6 is protruded into the inside of sucker 2 and is connected to sucker 2, and the other end of spring 6 protrudes into elastic ring 5, sets on spring 6 There are several vacuum sucking holes, the outer wall of elastic ring 5 is fixed with limit plate 4 by a bindiny mechanism.

Partition 7 is equipped in elastic ring 5, the inside of elastic ring 5 is separated into seal chamber 8 and connecting cavity 9 by partition 7, spring 6 One end is protruded into seal chamber 8, and bindiny mechanism includes the first threaded hole 10 being arranged in connecting cavity 9, and the first threaded hole 10 is along bullet Property 5 outer wall of circle circumferential direction be uniformly distributed, limit plate 4 be equipped with several second threaded holes 11, elastic ring 5 pass through screw rod 12 and first Threaded hole 10 and the second threaded hole 11 are fixedly connected.

The both ends of spring 6 are respectively equipped with the first sealing ring 13 and the second sealing ring 14, and the first sealing ring 13 is arranged in spring 6 With the junction of sucker 2, the junction of spring 6 Yu elastic ring 5 is arranged in the second sealing ring 14.

Telescopic rod 15 is equipped between limit plate 4 and chassis 3, limit plate 4 can be slided by telescopic rod 15 on chassis 3.

The end face of spring 6 and the end face of sucker 2.

Preferably, spring 6 is rubber spring, the damage of relatively thin part can be prevented during absorption.

The working principle of the utility model:

Negative pressure is generated with vacuum pump absorption vacuum, so as to adsorbent parts, when the size of part is more than sucker 2, The position at its edge is difficult to be adsorbed onto, so an elastic ring 5, elastic ring 5 and sucker is arranged in the external of sucker 2 in the utility model It is equipped with the hollow spring 6 being connected to sucker 2 between 2, while also being provided with vacuum sucking holes on spring 6, absorption can be increased Area, in addition, elastic ring 5 can also change as rectangle or profiled shape, specifically, by taking rectangle as an example, by the two of elastic ring 5 End is fixed by screw rod 12 and limit plate 4, and limit plate 4 is then stretched out a distance as needed, the position of spring 6 and Number can adjust according to actual needs.

The above are only specific embodiments of the present invention, but the technical characteristics of the utility model is not limited thereto.Appoint How based on the utility model, to solve essentially identical technical problem, essentially identical technical effect is realized, it is made Simple change, equivalent replacement or modification etc., are all covered by among the protection scope of the utility model.
