Abstract

The utility model discloses a tooling for mounting positioning pins and aims at providing the tooling which has convenient operation and simple structure and is applicable to mounting of the positioning pins on shaft parts with high precision. The tooling comprises a vertical rack and is characterized in that a through trench for placing a shaft is arranged in front of the rack, an upper through hole and a lower through hole are respectively arranged on the upper side surface and the lower side surface of the trench, an upper guide sleeve and a lower guide sleeve are respectively embedded in the upper through hole and the lower through hole, axial lines between an upper guide sleeve hole and a lower guide sleeve hole are required to be coaxial, vertical to the lower side surface and matched with the diameter of the positioning pin which is pressed in, a stepped shaft is mounted in the lower through hole, a guide pin which is matched with the lower guide sleeve hole is arranged at the small end of the stepped shaft, a jacking spring is mounted below the stepped shaft, and the length of the guide pin meets the following condition: when the stepped shaft is jacked by the jacking spring, the guide pin is higher than the lower side surface. The tooling has the advantages of accurate positioning, no skew of the positioning pin which is pressed in, convenient operation and high processing efficiency.

Description

The frock of alignment pin is installed

Technical field

The utility model relates to assembly tooling, particularly cooperates the frock of installation in axial workpiece high accurate hole radially with the high accuracy pin.

Background technology

In the conventional method that alignment pin radially is installed of axial workpiece, generally be to sell alignment pin holes with hammer to knock to squeeze into and get final product.This requirement for the operative employee is high especially, is easy to take place very much deflection, and influence cooperates intensity and precision, and for high-precision axial workpiece owing to knock the linearity generation gross distortion that can make axle, overproof and defective.

Summary of the invention

The purpose of this utility model provides a kind of easy to operate, and is simple in structure, is adapted at installing on the high-precision axial workpiece frock of alignment pin.

In order to achieve the above object, the tool structure that alignment pin is installed is: it includes upright frame, it is characterized in that being shaped on the perforation groove of shelving axle in the front of frame, upper side and downside at groove are shaped on through hole and lower through-hole respectively, in last through hole and lower through-hole, stud with upper guide bush and following guide pin bushing respectively, and require axis coaxle between upper guide bush hole and the following dowel hole, vertical with downside, match with the diameter of being pressed into alignment pin, multidiameter is installed in lower through-hole, the small end of multidiameter is that guide finger matches with following dowel hole, the jack-up spring is installed below the multidiameter, the length of guide finger is that guide finger exceeds downside when jack-up spring jack-up multidiameter.Be connected with the handle with the multidiameter axis normal on the described multidiameter, on frame, be shaped on the gathering sill that moves up and down for handle.

The frock of the installation alignment pin of making according to said structure, in use, the axle that will be processed with dowel hole earlier rests on the downside, and the guide finger that stretches out inserts in the dowel hole, implements the location.The alignment pin that need are pressed into is put into through hole, alignment pin is applied axial force, slowly and correctly alignment pin is pressed in the dowel hole by the pad axle.It is correct that whole frock has the location, and the alignment pin that is pressed into can deflection, easy to operate, advantage of high processing efficiency.

The specific embodiment

The utility model will be further described below in conjunction with accompanying drawing.

Fig. 1 is the state diagram of frock when beginning to press alignment pin that alignment pin is installed.As seen from the figure, it includes upright frame 1, be shaped on the perforation groove 3 of shelving axle 2 in the front of frame 1, upper side 4 and downside 5 at groove 3 are shaped on through hole 6 and lower through-hole 7 respectively, in last through hole 6 and lower through-hole 7, stud with upper guide bush 8 and following guide pin bushing 9 respectively, and require axis coaxle between upper guide bush hole 10 and the following dowel hole 11, vertical with downside 4, match with the diameter of being pressed into alignment pin 12, multidiameter 13 is installed in lower through-hole 7, the small end of multidiameter 13 is that guide finger 14 matches with following dowel hole 11, jack-up spring 15 is installed below the multidiameter 13, the length of guide finger 14 is that guide finger 14 exceeds downside when jack-up spring 15 jack-up multidiameters.Be connected with the handle 16 with multidiameter 13 axis normal on the described multidiameter 13, on frame 1, be shaped on the gathering sill 17 that moves up and down for handle 16.

In use, the axle 2 that will be processed with dowel hole 18 earlier rests on the downside, and the guide finger 14 that stretches out inserts in the dowel hole 18, implements the location.The alignment pin 12 that need are pressed into is put into through hole 6, apply axial force, slowly and correctly alignment pin 12 is pressed in the dowel hole 18 as shown in Figure 2, finish the installation of alignment pin 12 on axle 2 as shown in Figure 3 by 19 pairs of alignment pins 12 of pad axle.

Claims

1. the frock of alignment pin is installed, it includes upright frame, it is characterized in that being shaped on the perforation groove of shelving axle in the front of frame, upper side and downside at groove are shaped on through hole and lower through-hole respectively, in last through hole and lower through-hole, stud with upper guide bush and following guide pin bushing respectively, and require axis coaxle between upper guide bush hole and the following dowel hole, vertical with downside, match with the diameter of being pressed into alignment pin, multidiameter is installed in lower through-hole, the small end of its axis is that guide finger matches with following dowel hole, the jack-up spring is installed below the multidiameter, the length of guide finger is that guide finger exceeds downside when jack-up spring jack-up multidiameter.
