CN205519181U - Dash some instruments - Google Patents

Abstract

The utility model provides a dash some instruments, including guide base member, drift and nut, the drift is a plurality of, and it is fixed with the guide base member through the nut on the guide base member to distribute. The utility model discloses a dash some instruments is pressing the laggard line pulse point of cover to rivet tightly, prevents that the bush is owing to receive the influence of factor such as vibration and take place to drop in the use.

Description

A kind of punching point instrument

Technical field

This utility model relates to Machining Technology, particularly a kind of special construction punching point instrument.

Background technology

Existing punching point instrument is from the surface that need to rush a position, carries out vertically downward rushing a little.At housing cavity During middle pressure lining, the external diameter (φ 41.5) of the lining owing to being pressed into is bigger than the aperture (φ 30.92) of housing, Rivet tightly so cannot be carried out punching point.

Utility model content

In order to cannot be carried out the technical problem that punching point is riveted tightly, this reality after solving the gland in the presence of background technology Propose a kind of punching point instrument with novel, after gland, carry out punching point rivet tightly, prevent lining in use Owing to the impact of the factor such as vibrated falls off.

Technical solution of the present utility model is: a kind of punching point instrument, it is characterised in that: described punching point work Tool includes guiding matrix, drift and nut；Described drift is multiple, is distributed on guiding matrix and passes through Nut is fixed with guiding matrix.

Above-mentioned punching point instrument also includes plug, and described plug is carried out with guiding matrix effect by the through hole of housing Rush a little.

Above-mentioned drift is three, and described nut is three, connects one to one.

A punching point instrument of the present utility model, the most stable due to its structure, the quality therefore carrying out punching point is steady Fixed reliable, and simple to operate.

Fig. 1 (b) is that this utility model guides matrix schematic diagram；

Fig. 2 is of the present utility model to be embodied as schematic diagram；

Detailed description of the invention

Seeing Fig. 1 (a), Fig. 1 (b), the utility model proposes and a kind of new rush an instrument, this instrument utilizes Housing original structure guides before doing and designs.By plug 1, matrix 2, nut 3, drift 4 is guided to form. Drift 4 is loaded on guiding matrix 2, with nut 3, drift 4 is fixed on guiding matrix 2.Nut 3 Preferably both 3 with drift 4, be evenly distributed in guide matrix 2 periphery, formed one metastable Structure.

See Fig. 2, during use, the guiding matrix 2 loading onto drift 4 is placed in housing from side, makes to draw Leader and the housing bore of leading matrix 2 fit tightly, and use plug 1 to tap by through hole above and guide base Body carries out rushing a little.

Claims (3)

1. a punching point instrument, it is characterised in that: described punching point instrument includes guiding matrix, drift and spiral shell Cap；Described drift is multiple, is distributed on guiding matrix and is fixed with guiding matrix by nut.

Punching point instrument the most according to claim 1, it is characterised in that: described punching point instrument also includes core Rod, described plug carries out rushing a little with guiding matrix effect by the through hole of housing.
