Abstract
The present invention relates to lid seal groove depth special inspecting equipment on a kind of gear pump, including end face locating piece, instrumentation, split bush and clamp nut, the bottom surface of end face locating piece is plane, make a vertical through hole in the axle center of the end face locating piece, the bottom coaxial package of split bush in the through hole, one clamp nut of upper outside coaxial package of split bush；The sleeve of instrumentation is coaxially inserted into the axis hole of split bush, and the lower end of the measurement head of instrumentation extends to the outside of end face locating piece bottom surface.The present invention is a kind of for lid seal groove depth special inspecting equipment on the gear pump that is detected to lid seal groove depth on gear pump, the difficulty that can reduce detection using this equipment, speed, the accuracy of raising testing result of accelerating detection, are that the work of staff is provided a great convenience.
Description
Technical field
The present invention relates to detect technical field of tools, a kind of especially lid seal groove depth dedicated test on gear pump
Equipment.
Background technology
The seal groove very little covered on gear pump, its depth is only 0.5mm, and width is only 0.8mm, due to close
Sealing groove is undersized, therefore its depth cannot be detected using instruments such as general slide calliper rule, at present, can only
Detect, not only waste time and energy also there are problems that measurement result is inaccurate, measuring speed using indirect mode.
The content of the invention
It is convenient real it is an object of the invention to make up the deficiencies in the prior art part, there is provided a kind of compact structure
With lid seal groove depth special inspecting equipment on the gear pump of measurement result accuracy can be improved.
The purpose of the present invention is realized by following technological means：
Lid seal groove depth special inspecting equipment on a kind of gear pump, it is characterised in that：Including end face locating piece,
Instrumentation, split bush and clamp nut, the bottom surface of end face locating piece is plane, the end face locating piece
A vertical through hole is made in axle center, the bottom coaxial package of split bush in the through hole, split bush it is upper
One clamp nut of coaxial package on the outside of portion；The sleeve of instrumentation is coaxially inserted into the axis hole of split bush,
The lower end of the measurement head of instrumentation extends to the outside of end face locating piece bottom surface.
And, described instrumentation is dial gauge.
And, the outer surface of described split bush is formed with screw thread, and the engagement of clamp nut screw thread is arranged on opening
Axle sleeve outside.
And, the diameter of described measurement head lower end is less than 0.8mm.
Advantages and positive effects of the present invention are：
1st, this equipment is mainly made up of end face locating piece and instrumentation, and end face locating piece is pressed in the end of workpiece
Optimized integration positioning on face, the measurement head of instrumentation can be detected to seal groove depth.The detection method
It is very simple and convenient, and testing result can directly be read by dial gauge, ocular and clear, it is ensured that detection
The accuracy of result, and improve the efficiency of detection.
2nd, this equipment is positioned and clamp nut lock opening axle sleeve using end face, and this structure design may insure
In measurement process, the stability of instrumentation, it is to avoid it is rocked, so as to be conducive to improving the precision for measuring.
3rd, this equipment using split bush lock instrumentation sleeve, the good stability not only locked, and
Coupling mechanism force is uniform, therefore sleeve uniform force, is hardly damaged, and does not interfere with the accuracy of measurement result.
4th, this device structure is simple, easy to manufacture, easy to use, low cost and be convenient for carrying.
5th, the present invention is a kind of for covering sealing on the gear pump that is detected to lid seal groove depth on gear pump
Groove depth special inspecting equipment, the difficulty that can reduce detection using this equipment, speed, the raising for accelerating detection
The accuracy of testing result, is that the work of staff is provided a great convenience.
Brief description of the drawings
Fig. 1 is front view of the invention；
Fig. 2 is the A-A of Fig. 1 to sectional view.
Specific embodiment
Describe embodiments of the invention in detail below in conjunction with the accompanying drawings；It should be noted that the present embodiment is narration
Property, it is not limited, it is impossible to which protection scope of the present invention is limited with this.
Lid seal groove depth special inspecting equipment on a kind of gear pump, including end face locating piece 4, instrumentation 1,
Split bush 6 and clamp nut 2, the bottom surface of end face locating piece is plane, the axle center system of the end face locating piece
Go out a vertical through hole.The bottom coaxial package of split bush in the through hole, the upper outside of split bush
One clamp nut of coaxial package, the outer surface of split bush is formed with screw thread, and the engagement of clamp nut screw thread is arranged on
Split bush outside.Instrumentation in the present embodiment is dial gauge, and the sleeve 5 of instrumentation is coaxially inserted into
In the axis hole of split bush, the lower end of the measurement head 3 of instrumentation extends to the outer of end face locating piece bottom surface
Side, the diameter of measurement head lower end is less than 0.8mm.
Application method of the invention is：
First dial gauge is returned to zero, is measured by then measurement head is inserted in the seal groove of workpiece to be detected.
