Abstract

The utility model relates to a hole-locating jig, which comprises a locating pin. The bottom of the locating pin is clamped in a groove on a workbench. The hole-locating jig is characterized in that the width of the locating pin is larger than that of each open hole on a to-be-located work piece. A chamfer is respectively disposed on both sides of the top of the locating pin so as to form an oblique plane. A spring is supported between the locating pin and the bottom of the groove on the workbench. As for the open holes of different calibers on the work piece, after the hole-locating jig is adopted, both sides of each open hole are clamped on the oblique plane of the locating pin. When the work piece continues to be pressed downwards, the spring contracts so as to locate each open hole. Therefore, the open holes of any calibers all can be clamped on the oblique plane of the locating pin, and the hole-locating jig is capable of being adapted to the open holes of any calibers, greatly reduces processing difficulty and improves locating speed.

Description

The hole localization tool

Technical field

The utility model relates to a kind of tool that the perforate on the workpiece is positioned of being used for.

Background technology

For workpiece as shown in Figure 11, need position the perforate on it 2.During the location, tool such as Fig. 2 of employing are said, comprise that the bottom embeds the alignment pin 4 in the workbench 3, tend to wear a set bolt 5 in order to fixed locating stud 4 in the alignment pin 4, and the bottom of set bolt 5 screws in the workbench 3.

During the location, the perforate 2 of workpiece 1 is inserted in the alignment pin 4, realize the location.Its shortcoming is obvious, and promptly the size of alignment pin 4 must closely cooperate with the size of perforate 2, must make different alignment pins 4 for the perforate 2 of different size; Improved machining accuracy so greatly; And, need waste time and energy for the different alignment pin 4 of different perforates 2 processing.

Summary of the invention

The purpose of the utility model provides a kind of localization tool that can be fit to the perforate of virtually any size.

In order to achieve the above object; The technical scheme of the utility model has provided a kind of hole localization tool; Comprise alignment pin, the bottom of alignment pin snaps in the groove on the workbench, it is characterized in that: the width of said alignment pin is greater than the width of all perforates on the workpiece to be positioned; Thereby have chamfering in the both sides at said alignment pin top and form the inclined-plane, between the bottom portion of groove of said alignment pin and workbench, be supported with spring.

Preferably, in said alignment pin, be equipped with bolt, the bottom of bolt screws in the said workbench, and said spring is wrapped in outside the screw rod of bolt.

For the perforate of different bores on the workpiece, behind the tool that employing the utility model provides, the both sides of perforate are stuck on the inclined-plane of alignment pin, and when workpiece was continued to press down, spring shrank, thereby perforate is positioned.This shows that no matter the perforate of which kind of bore can be stuck on the inclined-plane of alignment pin, therefore, the localization tool that the utility model provides can adapt to the perforate of any bore, greatly reduces difficulty of processing, has improved the speed of location.

Fig. 1 is a workpiece sketch map to be positioned;

Fig. 2 is existing localization tool sketch map;

A kind of hole localization tool sketch map of Fig. 3 for providing among the embodiment 1;

A kind of hole localization tool sketch map of Fig. 4 for providing among the embodiment 2.

The specific embodiment

For making the utility model more obviously understandable, now with preferred embodiment, and conjunction with figs. elaborates as follows.

Embodiment 1

As shown in Figure 3; A kind of hole localization tool that the utility model provides; Comprise alignment pin 6, the bottom of alignment pin 6 snaps in the groove on the workbench 3, and the width of alignment pin 6 is greater than the width of all perforates 2 on the workpiece 1 to be positioned; Thereby have chamfering in the both sides at said alignment pin 6 tops and form the inclined-plane, between the bottom portion of groove of alignment pin 6 and workbench 3, be supported with spring 7.

In conjunction with Fig. 1, during the location, behind the perforate 2 aligned pins 6 with workpiece 1,, make perforate 2 be stuck on the inclined-plane of alignment pin 6 both sides with workpiece 1 pressed downward, continue to press down workpiece 1, spring 7 shrinks, and continues to press down workpiece 1 and props up workbench 3 until workpiece 1, accomplishes the location.

Embodiment 2

As shown in Figure 4, the difference of present embodiment and embodiment 1 is, in alignment pin 6, is equipped with bolt 8, and the bottom of bolt 8 screws in the workbench 3, and spring 7 is wrapped in outside the screw rod of bolt 8.Other structures and working method are identical with embodiment 1.

Claims

1. hole localization tool; Comprise alignment pin (6); The bottom of alignment pin (6) snaps in the groove on the workbench (3); It is characterized in that: the width of said alignment pin (6) is gone up the width of all perforates (2) greater than workpiece to be positioned (1), at said alignment pin (6) thus the both sides at top have chamfering forms the inclined-plane, between the bottom portion of groove of said alignment pin (6) and workbench (3), be supported with spring (7).

2. a kind of hole as claimed in claim 1 localization tool is characterized in that: in said alignment pin (6), be equipped with bolt (8), the bottom of bolt (8) screws in the said workbench (3), and said spring (7) is wrapped in outside the screw rod of bolt (8).
