Abstract

The utility model discloses a self-tapping steel sleeve taking-out device which comprises a No. 1 part, a No. 2 part and a No. 3 part; no. 3 the part couple together 1 part and No. 2 part, wherein, 1 part and No. 3 part are interference fit, 2 parts and No. 3 part are clearance fit, 2 parts can use No. 3 parts to carry out the rotation of certain angle as the axle. The self-tapping steel sleeve taking-out device reduces the rejection rate and the rework rate of the steel sleeve and a casting, improves the yield of products, reduces the production finished products of the device and improves the qualification rate of the products. The device is suitable for the mechanical industry and has certain guiding significance for assembling parts which are not high in hardness and need to be frequently disassembled or bear larger torsion.

Description

Self tapping steel bushing remove device

Technical Field

The utility model belongs to the field of electronic and semiconductor equipment assembly, and particularly relates to a self-tapping steel sleeve taking-out device.

Background

The existing casting is widely applied to the manufacture of industrial equipment and is an indispensable part for mechanical manufacture. The addition of steel sleeves to castings is the most common and effective means for improving their joint strength. At present, the steel sleeve added into the casting is difficult to take out, and a method for breaking the steel sleeve and taking out the steel sleeve is generally used, so that the steel sleeve and the casting can be broken.

SUMMERY OF THE UTILITY MODEL

Utility model purpose: in order to solve the defects of the prior art, the utility model provides the design and application of a self-tapping steel sleeve taking-out device. The tapping steel sleeve taking-out device can completely take out the steel sleeve on the basis of not damaging the steel sleeve and the casting.

The technical scheme is as follows: a self-tapping steel sleeve taking-out device comprises a No. 1 part, a No. 2 part and a No. 3 part; no. 3 the part couple together 1 part and No. 2 part, wherein, 1 part and No. 3 part are interference fit, 2 parts and No. 3 part are clearance fit, 2 parts can use No. 3 parts to carry out the rotation of certain angle as the axle.

As an optimization: no. 2 part can rotation angle under the effect of self gravity, also can be through rotatory No. 2 part of little needle, when No. 2 part gets into the recess of self tapping steel bushing, rotatory No. 1 part just can take out the steel bushing.

As an optimization: the excircle diameter of No. 1 part be the internal diameter of screw steel bushing that moves back, the hardness of No. 1 part is 65 HRC.

As an optimization: no. 2 part be the thimble separation blade, adopt eccentric design, No. 2 part's hardness is 75 HRC.

As an optimization: the No. 3 part is a rotating shaft.

Has the advantages that: the self-tapping steel sleeve taking-out device reduces the rejection rate and the rework rate of the steel sleeve and a casting, improves the yield of products, reduces the production finished products of the device and improves the qualification rate of the products. The device is suitable for the mechanical industry and has certain guiding significance for assembling parts which are not high in hardness and need to be frequently disassembled or bear larger torsion.

Detailed Description

Examples

As shown in fig. 1, a self-tapping steel sleeve removing device comprises a part 1, a part 2 and a part 3; no. 3 part 3 connect together 1 part 1 and No. 2 part 2, wherein, 1 part 1 and No. 3 part 3 are interference fit, 2 part 2 and No. 3 part 3 are clearance fit, 2 part 2 can use 3 part 3 to carry out the rotation of certain angle as the axle.

In this embodiment, the No. 2 part can rotate the angle under the effect of self gravity, also can be through the rotatory No. 2 part of little needle, and when No. 2 part entered the recess of self tapping steel bushing, rotatory No. 1 part 1 just can take out the steel bushing.

In the embodiment, the diameter of the excircle of the No. 1 part 1 is the inner diameter of the withdrawn threaded steel sleeve, and the hardness of the No. 1 part 1 is 65 HRC. No. 2 part 2 be the thimble separation blade, adopt eccentric design, No. 2 part's hardness is 75 HRC. The No. 3 part 3 is a rotating shaft.

The self-tapping steel sleeve taking-out device reduces the rejection rate and the rework rate of the steel sleeve and a casting, improves the yield of products, reduces the production finished products of the device and improves the qualification rate of the products. The device is suitable for the mechanical industry and has certain guiding significance for assembling parts which are not high in hardness and need to be frequently disassembled or bear larger torsion.

The technical solutions in the embodiments of the present invention are clearly and completely described above, so that those skilled in the art can better understand the advantages and features of the present invention, and thus the protection scope of the present invention is more clearly defined. The embodiments described herein are only a few embodiments of the present invention, rather than all embodiments, and all other embodiments that can be derived by one of ordinary skill in the art without inventive faculty based on the embodiments described herein are intended to fall within the scope of the present invention.
