The utility model relates to an it is convenient that is used for the counter gear pump upper cover seal groove degree of depth to carry out the special detection device of gear pump upper cover seal groove degree of depth who detects, use this device can reduce the detection the degree of difficulty, the speed that accelerate to detect, improve the accuracy of testing result, for staff's work provides greatly.
Description
Technical field
This utility model relates to detection technical field of tools, especially a kind of gear pump upper cover seal groove degree of depth special detection device。
Background technology
The seal groove of gear pump upper cover is only small, its degree of depth is only 0.5mm, width is only 0.8mm, owing to seal groove is undersized, therefore use the instruments such as general slide calliper rule cannot its degree of depth be detected, at present, indirect mode can only be adopted to detect, not only waste time and energy, there is also the problems such as measurement result is inaccurate, measuring speed is slow。
Utility model content
The purpose of this utility model is in that to make up the deficiencies in the prior art part, it is provided that a kind of compact structure, convenient and practical, can improve the gear pump upper cover seal groove degree of depth special detection device of measurement result accuracy。
The purpose of this utility model is realized by techniques below means:
A kind of gear pump upper cover seal groove degree of depth special detection device, it is characterized in that: include end face locating piece, instrumentation, split bush and clamp nut, the bottom surface of end face locating piece is plane, a vertical through hole is made in the axle center of this end face locating piece, the bottom coaxial package of split bush in this through hole, one clamp nut of the upper outside coaxial package of split bush；The sleeve of instrumentation is coaxially inserted in the axis hole of split bush, and the lower end measuring 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 shaped with screw thread, and clamp nut screw-threaded engagement is arranged on outside split bush。
And, the described diameter measuring head lower end is less than 0.8mm。
Advantage of the present utility model and having the benefit effect that
1, this device is mainly made up of end face locating piece and instrumentation, the location that is pressed on the end face of workpiece by end face locating piece optimized integration, and the seal groove degree of depth can be detected by the measurement head of instrumentation。This detection method is very simple and convenient, and testing result can directly be read by dial gauge, ocular and clear, it is ensured that the accuracy of testing result, and improves the efficiency of detection。
2, this device uses end face location and clamp nut lock opening axle sleeve, and this structural design may insure that in measurement process, the stability of instrumentation, it is to avoid it rocks, thus being conducive to improving the precision measured。
3, this device adopts the sleeve of split bush locking instrumentation, the good stability not only locked, and coupling mechanism force is uniform, and therefore sleeve uniform force is hardly damaged, without influence on the accuracy of measurement result。
4, this apparatus structure is simple, easy to manufacture, easy to use, cost is low and is convenient for carrying。
5, this utility model is a kind of gear pump upper cover seal groove degree of depth special detection device for the gear pump upper cover seal groove degree of depth is detected, using this device can reduce the difficulty of detection, accelerate the accuracy of the speed of detection, raising testing result, the work for staff provides a great convenience。
Accompanying drawing explanation
Fig. 1 is front view of the present utility model；
Fig. 2 is that the A-A of Fig. 1 is to sectional view。
Detailed description of the invention
Embodiment of the present utility model is described in detail below in conjunction with accompanying drawing；It should be noted that the present embodiment is narrative, it not determinate, it is impossible to limit protection domain of the present utility model with this。
A kind of gear pump upper cover seal groove degree of depth special detection device, 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, and a vertical through hole is made in the axle center of this end face locating piece。The bottom coaxial package of split bush is in this through hole, and one clamp nut of the upper outside coaxial package of split bush, the outer surface of split bush is shaped with screw thread, and clamp nut screw-threaded engagement is arranged on outside split bush。Instrumentation in the present embodiment is dial gauge, and the sleeve 5 of instrumentation is coaxially inserted in the axis hole of split bush, and the lower end of the measurement 3 of instrumentation extends to the outside of end face locating piece bottom surface, measures the diameter of head lower end less than 0.8mm。
Using method of the present utility model is:
First dial gauge is returned to zero, then measurement head is inserted in the seal groove of workpiece to be detected and can measure。
