Sand blowing clamp structure for metal piece

Abstract

The utility model discloses a sand blasting clamp structure for a metal piece. The sand blasting clamp structure comprises a top protective sleeve and a bottom protective sleeve, the bottom of the annular protective sleeve is inserted into the annular groove of the metal piece; the outer side protective sleeve sleeves the outer side edge of the top surface of the metal piece; the outer side protective sleeve, the annular protective sleeve and the top protective sleeve are arranged at intervals and are not connected with one another. The outer side protection sleeve, the annular protection sleeve and the top protection sleeve are not connected with one another, the annular protection sleeve is axially pulled out through the protruding part to be stressed and pulled out of the annular groove of the metal piece, and the problem that the sand blowing clamp is integrally damaged due to the fact that the annular plug body is connected with the sand blowing clamp through two symmetrical connecting arms when the connecting arms are taken out is solved.

Description

Technical Field

[0001] The utility model relates to a metal part sand blasting fixture structure and belongs to the technical field of sand blasting fixtures. Background Art

[0002] During the processing of metal parts, sometimes specific parts need to be sandblasted, while parts that do not need sandblasting need to be protected.

[0003] For the metal part 1 with the annular groove 11, see Figure 4 After the existing protective sand blasting fixture 2 wraps the metal part 1, the annular groove 11 of the metal part 1 is inserted into the annular plug 21 of the sand blasting fixture 2. Figure 3 Although the annular plug 21 and the sand blasting fixture 2 can protect the parts of the metal part 1 that do not need sand blasting processing, since the annular plug 21 is connected to the sand blasting fixture 2 through two symmetrical connecting arms 22, the connecting arms 22 are prone to breakage when being removed, resulting in damage to the entire sand blasting fixture. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a metal part sand blasting fixture structure.

[0005] The utility model is realized through the following technical solutions.

[0006] The utility model provides a metal part sand blasting fixture structure, comprising:

[0007] A top protective cover that fits over the top of the metal piece;

[0008] An annular protective sleeve with a bottom portion inserted into an annular groove of the metal piece;

[0009] An outer protective cover covering the outer edge of the top surface of the metal part;

[0010] The outer protective cover, the annular protective cover and the top protective cover are spaced apart from each other and are not connected to each other.

[0011] The outer protective cover, the annular protective cover and the top protective cover are all made of rubber.

[0012] The bottom of the annular protective sleeve inserted into the annular groove of the metal piece is inclined inwards.

[0013] Protrusions are fixed on both sides of the top of the annular protective sleeve.

[0014] The protruding portion is integrally and fixedly connected to the annular protective sleeve.

[0015] The beneficial effects of the utility model are that the outer protective sleeve, the annular protective sleeve and the top protective sleeve are not connected to each other, and the annular protective sleeve is pulled out from the annular groove of the metal part by axially pulling out through the protrusion, thereby solving the problem that the annular blocking body is connected to the sand blasting fixture through two symmetrical connecting arms, and the connecting arms are easily broken when being taken out, resulting in overall damage to the sand blasting fixture.

[0022] The technical solution of the utility model is further described below, but the scope of protection required is not limited to the description.

[0023] like Figure 1 to Figure 2 shown.

[0024] A metal part sand blasting fixture structure of the present application includes:

[0025] The top protective cover 31 is inserted into the top of the metal part 1 and is made of rubber. The top protective cover 31 is inserted into the top of the metal part 1 to avoid wasting a long time by wrapping the top of the metal part 1 with cloth for protection.

[0026] It also includes an annular protective sleeve 32 with an inwardly inclined bottom. The bottom of the annular protective sleeve 32 is inclined so that it can be quickly inserted into the annular groove 11 of the metal component 1; protrusions 321 are fixed on both sides of the top of the annular protective sleeve 32, and the protrusions 321 can carry the annular protective sleeve 32 to rotate in the annular groove 11 to protect and cover the damaged part of the top protective sleeve 31, and at the same time, the annular protective sleeve 32 can be pulled out of the annular groove 11 of the metal component 1 by force through the protrusions 321.

[0027] It also includes an outer protective sleeve 33 covering the outer edge of the top surface of the metal part 1, and the outer circumference of the outer protective sleeve 33 is larger than the outer edge of the top surface; the outer protective sleeve 33, the annular protective sleeve 32 and the top protective sleeve 31 are spaced apart and not connected to each other.

[0028] When removing the entire sand blasting fixture, since the outer protective sleeve 33, the annular protective sleeve 32 and the top protective sleeve 31 are not connected to each other, the annular protective sleeve 32 is pulled axially by the protrusion 321 and is pulled out of the annular groove 11 of the metal part 1. This solves the problem that the annular blocking body 21 is connected to the sand blasting fixture 2 through two symmetrical connecting arms 22, and the connecting arms 22 are prone to breakage during removal, resulting in damage to the entire sand blasting fixture; then, the outer protective sleeve 33 is detached and removed from the outer edge of the top surface of the metal part 1, and the top protective sleeve 31 is detached and removed from the top of the metal part 1.
