Abstract

The utility model relates to a special tester for a radiator, belonging to a measuring tool and a testing tool. The utility model is composed of the special plug gauge of a thread central distance, a dial gauge, a connecting rod composed of an external connecting rod and an inner connecting rod. The utility model has the advantages of simple structure, and long service life, etc. The measuring accuracy and the testing speed can be increased.

Description

Special tester for radiator

The utility model is a kind of heating radiator appliance special for detecting, belongs to appliance.

At present, the producer that produces heating radiator when centre distance and verticality, adopts plug thread gauge to check accuracy of thread at the accuracy of thread of checking heating radiator respectively, detects feeler gauge with centre distance, centre distance indicator bracket, inspection side centre distance.Check verticality with the special-purpose feeler gauge of verticality, detect heating radiator check trouble with above-mentioned cubing, and the cubing quick abrasion.

It is convenient that the purpose of this utility model provides a kind of check, the efficient height, and little heating radiator appliance special for detecting weares and teares.

The utility model is realized with following technical scheme: the amount post of reprocessing out one section inspection center's distance on the drift or the no-go gage neck end top of plug thread gauge is merged into one with the amount post rule of the plug thread gauge of former separation and inspection center's distance and can detects thread center that accuracy of thread simultaneously again can inspection center's distance apart from special-purpose feeler gauge.Make the guide pin bushing of former dial gauge into screw thread coupling, make former dial framework into extension bar, extension bar is made up of interior extension bar and outer extension bar.Interior extension bar is contained in the outer extension bar, and a spring is housed on the interior extension bar, is processed with a convex shoulder platform at the mounting spring place.The screw thread coupling of the dial gauge after outer extension bar one end is processed with a threaded hole and changes a social system modification is connected, and is processed with a locating piece in the threaded hole, and the extension bar location is used in being used for.The outer extension bar other end is processed a threaded post, and the location buting iron is equipped with at extension bar threaded post place outside, is fixed by nut.

The utlity model has simple in structurely, long service life improves the characteristics of measuring accuracy and detection speed.

Now the utility model is described in further detail in conjunction with the accompanying drawings.

Fig. 1 is that the utility model detects synoptic diagram.

Fig. 2 is the utility model front view.

Fig. 3 is the cut-open view of the utility model extension bar.

Fig. 4 is the front view of the utility model thread center apart from special-purpose feeler gauge.

Fig. 1～4th, specific embodiment of the utility model, can detect the amount post 10 that thread center that accuracy of thread simultaneously again can inspection center's distance reprocesses out one section inspection center's distance apart from the no-go gage or the drift neck end of special-purpose feeler gauge 1, the guide pin bushing of former dial gauge 2 makes screw thread coupling 3 into, and extension bar 4 is made up of interior extension bar 8 and outer extension bar 7.Interior extension bar 8 is contained in the outer extension bar 7.One spring 9 is housed on the interior extension bar 8, at interior extension bar 8 spring 9 places is housed and is processed with a convex shoulder platform.Outer extension bar 7 one ends are processed with a threaded hole and are connected with the screw thread coupling 3 of transformation of the way distortion back dial gauge 2.Be processed with a locating piece in the threaded hole, extension bar 8 location are used in being used for.Outer extension bar 7 other ends are processed a threaded post, and location buting iron 5 is equipped with at outer extension bar 7 threaded post places, and are fixing by nut 6.

Claims

1, a kind of heating radiator appliance special for detecting, it is characterized in that the amount post 10 that thread center processes one section inspection center's distance apart from the no-go gage or the drift neck end of special-purpose feeler gauge 1, dial gauge 2 one end guide pin bushings make screw thread coupling 3 into, extension bar 4 is made up of interior extension bar 8 and outer extension bar 7, screw thread coupling 3 is connected the threaded hole of dial gauge 2 with outer extension bar 7, interior extension bar 8 is contained in the outer extension bar 7, on the interior extension bar 8 spring 9 is housed, interior extension bar 8 shock mounts 9 places are processed with a convex shoulder platform, outer extension bar 7 one ends are processed with a threaded hole, are processed with a positioning block in the threaded hole, and outer extension bar 7 other ends are processed a threaded post, positioning baffle 5 is equipped with at the threaded post place, and is fixing by nut 6.
