Abstract
The utility model relates to the field of product detection and particularly relates to a center distance detection device. The center distance detection device is capable of quickly detecting center distance between holes and small in error. The center distance detection device comprises a base and is characterized in that a fixed conical pin and a movable conical pin are installed on the base, the bottom of the movable conical pin is connected with a ball bearing, and the ball bearing is connected with a mechanical meter.
Description
Technical field
The utility model relates to the product detection field, is specially a kind of center distance check tool.
Background technology
The parts of auto parts and components cover plate one class are because the installation requirements operated by rotary motion has more mounting hole, it not only has specification requirement to the pore size of mounting hole, centre distance for Kong Yukong also has specification requirement, generally first distinguish distance and pore size between measured hole, and then calculate, so just have larger error, and detection efficiency is lower.
Summary of the invention
In order to address the above problem, the utility model provides a kind of center distance check tool, and it can detect the centre distance of portalling with the hole fast, and error is little.
Its technical scheme is such: it comprises base, it is characterized in that, fixedly tapered pin, a removable tapered pin is installed on described base, and described removable tapered pin bottom connects ball bearing, and described ball bearing connects stem-winder.
It is further characterized in that, is provided with dismountable calibrating device on described base, is provided with the calibration hole that coordinates with described fixedly tapered pin, removable tapered pin on described calibrating device; Described fixedly tapered pin, removable tapered pin connect described base by spring; Described stem-winder is installed on described base by gauge stand.
After adopting structure of the present utility model, one fixedly tapered pin, a removable tapered pin is installed on base, removable tapered pin bottom connects ball bearing, ball bearing connects stem-winder, tested workpiece is by fixedly tapered pin, removable tapered pin are located, by the stem-winder reading, can detect fast the centre distance of portalling with the hole, error is little.

Embodiment
See Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, it comprises base 1, and fixedly tapered pin 2, a removable tapered pin 3 is installed on base 1, and removable tapered pin 3 bottoms connect ball bearing 4, and ball bearing 4 connects stem-winders 5; Fixedly tapered pin 2, removable taper 3 connect base 1 by spring 6, stem-winder 5 is installed on base 1 by gauge stand 7, be provided with dismountable calibrating device 9 on base 1, be provided with the calibration hole 10 that coordinates with fixedly tapered pin 2, removable tapered pin 3 on calibrating device 9.
its testing process is as described below: fixedly tapered pin 2, removable tapered pin 3 are aimed at respectively in two holes of tested workpiece 8, then be positioned on base 1, make fixedly tapered pin 2, removable tapered pin 3 and hole chucking, determine the centre distance of Kong Yukong by stem-winder 5 readings, judge whether up to specification, when calibrating device 9 is arranged, the calibration hole 10 of calibrating device 9 is aimed at fixedly tapered pin 2, removable tapered pin 3 is placed, make calibration hole 10 and fixing tapered pin 2, removable tapered pin 3 chuckings are calibrated reading, then take calibrating device 9 away, tested workpiece 8 is put, make the hole of workpiece 8 and fixing tapered pin 2, removable tapered pin 3 chuckings, if stem-winder 5 readings are constant, up to specification, drive ball bearing 4 moves stem-winder 5 readings is changed if removable tapered pin 3 is moved, change according to reading and judge whether in error range, thereby judge whether up to specification, fixedly tapered pin 2, removable taper 3 connects bases 1 by spring 6, can fluctuate, and makes the hole and fixedly tapered pin 2, removable taper 3 more easily tighten.
