Description
Technical field:
The utility model belongs to the manufacturing technology technical field, relates to a kind of device of measurement mechanical parts endoporus diameter of ring groove size, especially a kind of inside groove calliper.
Background technology:
At present, the septal fossula rule that can see on the market, it measures endoporus diameter of ring groove scope generally is between 50～160mm, it fathoms also very limited.Run into need to measure diameter greater than the 160mm size in, measure by the cross calliper of 1: 1 ratio usually, can only reach 11 grades but its measuring accuracy is the highest.Now in our actual production; the macropore seal groove that runs into 8～9 grades of precision through regular meeting is measured; can only pass through at macropore Nei Labiao; measure the difference of groove bottom and inner hole surface; calculate the diameter of seal groove; not only trouble is gone up in operation, and owing to be to measure in the hole, sees that meter reading is also difficult.
The utility model content:
In order to overcome the problem that exists in the background technology, the utility model provides a kind of inside groove calliper, and this calliper is measured endoporus diameter of ring groove scope at 155～245mm, even bigger, and it fathoms and also can reach more than the 240mm, and convenient reading is measured accurately.
The technical solution of the utility model is: this inside groove calliper comprises that an end has the mobile test arm of cylinder gauge head and fixing test arm, the other end of mobile test arm is for colluding trigger action, fixedly the other end of test arm is main connector, the dial gauge body is arranged on the main connector, the main connector of dial gauge body below and an end of control with changed scale casket housing fix, control with changed scale casket housing has support and mobile rack in the chamber, the lower end of mobile rack is with to collude trigger action hinged, the support upper end is stretched out control with changed scale casket housing and is fixed on main connector, the support bottom is provided with the sliding rack that can slide up and down, conjuncted gear wheel and pinion wheel are installed in the support bottom, pinion wheel is meshed with sliding rack, gear wheel is meshed with mobile rack, the upper end of sliding rack all the time with extend into control with changed scale casket housing in the lower surface of contact of indicator of dial gauge touch mutually.
Groove is arranged on the above-mentioned mobile rack vertically, have two guideposts in the groove at least, guidepost is fixed on the control with changed scale casket inner walls; Groove is arranged on the sliding rack vertically, have two guideposts in the groove at least, guidepost is fixed on the support.
The utlity model has following beneficial effect: this novel measurement mechanical parts endoporus diameter of ring groove size that is used for is particularly useful for measuring apart from the big darker and narrow seal groove of hole end surface.This novel structure in conjunction with cross calliper and septal fossula rule, being designed to main body is the cross articulated structure, and gauge head is wanted to go deep into narrower endoporus seal groove bottom, and gauge head is selected wear-resistant material for use.Because the diameter that will measure is bigger, exposes a test arm and is designed to handle structure, another test arm is designed to collude the trigger action structure.The two ends test arm length ratio that body surveyed in cross is 2: 1, passes through 5: 1 control with changed scale caskets again, the actual range that moves is fallen than 10: 1 pass to the dial gauge contact that is fixed on the calliper main body, reads measurement result.Convenient reading is measured accurately.Can measure larger-diameter endoporus seal groove diameter, measure endoporus diameter of ring groove scope at 155～245mm, in addition bigger, and it fathoms and also can reach more than the 240mm.
