Abstract

The utility model relates to a shot blasting protection tool and has the beneficial effects that the shot blasting protection tool can be machined by a nylon stick, the nylon stick is flexible in texture, threads can be machined on the nylon stick conveniently, the abrasion is less after shot blasting, the service life is long, and the cost is low; the conical surface of the protection tool is adopted to protect an air vent, the outer surface of a workpiece is not covered, the phenomenon of shot-blasting missing is avoided, the integral appearance of the workpiece is attractive after shot blasting, when the conical surface is used for protection, no gap is formed between the conical surface and the workpiece, and the phenomenon that the interior of the air vent is scratched is avoided; the nylon stick is flexible in texture, causes no dents to the workpiece and cannot damage the workpiece, the protection tool has larger working allowance, and the requirement on machining precision is low.

Description

A kind of ball blast protection frock

1, technical field

The utility model relates to a kind of ball blast protection frock, the protecting tool set-up that specifically a kind of passage (8) that is used for protecting workpiece (workpiece shown in the similar Figure of description 3) is injury-free in process such as ball blast, sandblast, scratch.

2, background technology

Workpiece shown in accompanying drawing 3 (7) is being carried out ball blast or sandblast adds man-hour; The roughness that requires because of the passage (8) of workpiece (7) is lower, and does not allow to scratch, so must carry out sealing protection to passage (8); Usually the useful nuts and bolt of method that adopts carries out two-sided protection to passage; But when adopting the method, nut also can hide a part of workpiece outer surface, influences whole workpiece ball blast effect; Tighten and on workpiece (particularly stainless steel work-piece), to leave impression during the bolts and nuts assembling, workpiece is caused damage.

3, utility model content

In view of the deficiency of above-mentioned prior art, the utility model provides a kind of ball blast protection frock.

The utility model solves the technical scheme that its technical problem adopted: two sections thick nylon rods of intercepting, one section nylon rod threading, one section nylon rod machining internal thread; The diameter of two screw threads is identical; External screw thread is long slightly than internal thread, and the external screw thread root leaves escape, and taper seat is processed on the face of cylinder of workpiece; When the second portion external screw thread assembling of the internal thread of the first of frock and frock, the passage both sides of workpiece are protected through taper seat.

The beneficial effect of the utility model is, can adopt nylon rod to process, and nylon rod matter is soft, and machining screw is convenient, and wearing and tearing are less behind the ball blast, long service life, and cost is low; Adopt the taper seat of frock that passage is protected, do not hide the workpiece outer surface, do not have to leak and throw phenomenon, whole workpiece is attractive in appearance behind the ball blast, and is seamless between taper seat and the workpiece when adopting the taper seat protection, do not have the inner phenomenon of the passage of scuffing; Nylon rod matter is soft, can not cause impression to workpiece, the damage workpiece, and the protection frock leaves bigger allowance, and requirement on machining accuracy is low.

4, description of drawings

Installation diagram when accompanying drawing 1 plays protective action for frock shell and frock inner casing to the passage of workpiece.

Among the figure, 1, the frock shell, 2, the shell taper seat, 3, internal thread.4, frock inner casing; 5, inner casing taper seat, , external screw thread.7, workpiece, 8, passage.

5, the specific embodiment

Explanation at length below with regard to accompanying drawing the utility model spy being done below.

See accompanying drawing, the utility model is a kind of ball blast protection frock, and frock is divided into two parts; Be respectively frock shell (1) and frock inner casing (4), can have nylon rod to process, two sections nylon rods of intercepting; The internal thread (3) that one section processing tool shell (1) is inner, the external screw thread (6) on one section processing tool inner casing (4), the equal diameters of two screw threads; Internal thread (3) is long slightly than external screw thread (6), and external screw thread (6) root leaves escape, and taper seat (2,5) is processed on the face of cylinder of nylon rod; Frock shell (1) and frock inner casing (4) are put into passage (8) inside, when assembling, protect with the passage (8) of taper seat (2,5) to workpiece through screw thread.

Nylon rod matter is soft, and machining screw is convenient, and wearing and tearing are less behind the ball blast, long service life, and cost is low; Adopt taper seat that passage is prevented expanding, do not hide the workpiece outer surface, do not have to leak and throw phenomenon, whole workpiece is attractive in appearance behind the ball blast, and is seamless between taper seat and the workpiece when adopting the taper seat protection, do not have the phenomenon that scratches passage; Nylon rod matter is soft, can not cause impression to workpiece, the damage workpiece, and the protection frock leaves bigger allowance, and requirement on machining accuracy is low.

Claims

1. a ball blast protects frock, and it is characterized in that: frock is divided into two parts, is respectively frock shell (1) and frock inner casing (4); Can process two sections nylon rods of intercepting, the internal thread (3) that one section processing tool shell (1) is inner by nylon rod; External screw thread (6) on one section processing tool inner casing (4); The equal diameters of two screw threads, internal thread (3) is long slightly than external screw thread (6), and external screw thread (6) root leaves escape; Taper seat (2,5) is processed on the face of cylinder of frock, can frock shell (1) and frock inner casing (4) be put into passage (8) inside.
