Abstract
The utility model discloses a kind of detection means for being used to detect crosshead screwed hole and outer circles, it includes detection bar, it is characterised in that：The detection bar includes thread segment and light bar segment, the light bar segment is symmetricly set on the both ends of thread segment, the detection bar is used to be installed on crosshead, and the thread segment of the detection bar is used to close with the corresponding threaded holes of crosshead, and detection table is each equipped with two light bar segments of detection bar.The utility model is by setting detection bar, the geometric center position of the detection bar is coordinated with crosshead by screw thread, both ends are to being referred to as light bar segment, so in detection, the light bar segment at both ends is poised state, which side would not occur and weigh the problem of which side is light, can correctly reflect crosshead screwed hole and the cylindrical axiality of crosshead, effectively raise testing result.
Description
Technical field
It the utility model is related to a kind of detection means for being used to detect crosshead screwed hole and outer circles.
Background technology
Crosshead screwed hole and its outer circles are an important Geometrical Tolerance Principles of compressor, and generally use is by ten
Prefix is cylindrical to be fallen on V shape iron, and piston rod is screwed in cross head thread, and the mode that table is played at the both ends of piston rod detects, and is led to
Multiple rotary cross head is crossed, table measurement is repeatedly played on piston rod is cylindrical, to judge outside the cylindrical each bus of piston rod and crosshead
The depth of parallelism of circle bus, so as to detect cross head thread and the cylindrical axiality of crosshead.Due to crosshead and piston rod thread
Cooperation is that gap coordinates, and piston rod is screwed in cross head thread in one end of piston rod by the connection screw thread of piston rod and crosshead
Interior, one end can sink piston rod under gravity, cause this detection mode error too big, it is impossible to correctly to reflect crosshead
Screwed hole and the cylindrical axiality of crosshead.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of energy for above-mentioned the shortcomings of the prior art
Improve the detection means for being used to detect crosshead screwed hole and outer circles of accuracy of detection.
Technical scheme is used by the utility model：A kind of inspection for being used to detect crosshead screwed hole and outer circles
Device is surveyed, it includes detection bar, it is characterised in that：The detection bar includes thread segment and light bar segment, and the light bar segment is symmetrically set
Put at the both ends of thread segment, the detection bar is used to be installed on crosshead, and the thread segment of the detection bar is used for and crosshead
Corresponding threaded holes close, be each equipped with detection table in two light bar segments of detection bar.
By above-mentioned technical proposal, in addition to v block, crosshead it is cylindrical fall on v block.
By above-mentioned technical proposal, the external diameter of the light bar segment is less than the core diameter of thread of thread segment.
By above-mentioned technical proposal, the identical length of two light bar segments etc..
By above-mentioned technical proposal, the thread segment of the detection bar and the screwed hole of crosshead coordinate for gap.
By above-mentioned technical proposal, the geometric center of the detection bar is located at the geometric center of crosshead screwed hole.
In detection, crosshead is positioned on v block, detection bar is screwed in crosshead connection screw thread, and make detection
The geometric center of bar is located at the geometric center of crosshead connection screw thread, then plays table, measurement detection at the both ends of detection bar respectively
The difference in height at bar both ends, rotate crosshead, measure the height at detection bar both ends again, so as to measure crosshead screwed hole with it is cylindrical
Coaxial angle value.
Having the beneficial effect that acquired by the utility model：The utility model by setting detection bar, the detection bar it is several
What centre is coordinated with crosshead by screw thread, and both ends are to being referred to as light bar segment, and so in detection, the light bar segment at both ends is flat
Weighing apparatus state, would not occur which side weight which side it is light the problem of, can correctly reflect cylindrical coaxial of crosshead screwed hole and crosshead
Degree, effectively raises testing result.
Brief description of the drawings
Fig. 1 is structure chart of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in figure 1, present embodiments provide a kind of detection dress for being used to detect crosshead screwed hole and outer circles
Put, it includes detection bar 2 and v block 4.The detection bar 2 includes thread segment 6 and light bar segment 5, and the light bar segment 5 is symmetrical arranged
At the both ends of thread segment 6, the identical length of two light bar segments etc..The external diameter of the light bar segment is less than the bottom footpath of thread segment.The inspection
Measuring staff 2 is used to be installed on crosshead 3.
In detection, crosshead 3 is positioned on v block 4, detection bar 2 screwed in the connection screw thread hole of crosshead 3,
And the geometric center of detection bar is located at the geometric center of crosshead connection screw thread, wherein, the thread segment and crosshead of detection bar
Screwed hole be that gap coordinates, then detection table 1 is set at the both ends of detection bar respectively, the difference in height at measurement detection bar both ends,
Crosshead is rotated, the height at detection bar both ends is measured again, so as to measure crosshead screwed hole and outer circles value.
