Device for adjusting circular degree of non-metallic ring

Abstract

The invention relates to a device for adjusting the circular degree of a non-metallic ring. The device comprises a circular tube sleeve and an adjusting rod, wherein the adjusting rod extends into thecircular tube sleeve and is movably arranged in the circular tube sleeve; the end parts of the circular tube sleeve and the adjusting rod are respectively provided with a supporting block; and the outer surface of each supporting block is arc. The length of the part, extending into the circular tube sleeve, of the adjusting rod makes the length of the adjusting device to be in a minimum state; the adjusting device is placed in the inner hole of a non-metallic circular ring; then the adjusting rod is adjusted to move in the circular tube sleeve so as to allow the length of the adjusting deviceto increase until the supporting blocks at the end parts of the circular tube sleeve and the adjusting rod contact with the surface of the inner hole of the non-metallic circular ring; and thus, theadjustment of the circular degree of the non-metallic ring is completed. Compared with the prior art, the device of the invention has the advantages of convenience in the adjustment of the circular degree, simple structure, convenient and reliable operation.

Description

technical field [0001] The invention relates to a roundness adjustment device, in particular to a non-metallic ring roundness adjustment device. Background technique [0002] The non-metallic ring (PTFE, PEEK material) blank is bonded to the wooden board. For the non-metallic ring blank with out-of-tolerance roundness, there is no device to adjust the roundness of the blank. It is difficult to control the roughness of the blank during the manufacture of non-metallic ring raw materials. roundness, resulting in a larger diameter ( The roundness error of the above) blanks is generally above 8mm, and even the roundness error of some large-diameter blanks exceeds 20mm. In order to ensure that there is a margin for machining, the thickness of the blank has to be left a lot, resulting in a waste of raw materials. Even so, when we are machining, we often encounter the phenomenon that there is not enough machining allowance during turning due to the out-of-tolerance roundness of th...

[0002] The non-metallic ring (PTFE, PEEK material) blank is bonded to the wooden board. For the non-metallic ring blank with out-of-tolerance roundness, there is no device to adjust the roundness of the blank. It is difficult to control the roughness of the blank during the manufacture of non-metallic ring raw materials. roundness, resulting in a larger diameter ( The roundness error of the above) blanks is generally above 8mm, and even the roundness error of some large-diameter blanks exceeds 20mm. In order to ensure that there is a margin for machining, the thickness of the blank has to be left a lot, resulting in a waste of raw materials.

Even so, when we are machining, we often encounter the phenomenon that there is not enough machining allowance during turning due to the out-of-tolerance roundness of the blank, and the resulting material scrap will cause great economic losses to the enterprise
