Abstract
The utility model discloses a coaxiality detection device for two holes, which comprises a positioning body A (4) and a positioning body B (5). Both the positioning body A (4) and the positioning body B (5) are disk-shaped. The external diameter of the positioning body A (4) equals to the internal diameter of one of two holes, wherein the hole is smaller than the other hole. The external diameter of the positioning body B (5) equals to the internal diameter of the other hole of the two holes. Both the positioning body A (4) and the positioning body B (5) are connected with the corresponding holes in a clearance fit manner. The positioning body A (4) is connected with the positioning body B (5) via a connection shaft (6). The length of the connection shaft (6) equals to the distance between the two holes. The axial lead of the positioning body A (4) and the axial lead of the positioning body B (5) are mutually superposed. The beneficial effects of the utility model are that the coaxiality detection device for two holes is simple in structure, easy in processing, convenient and fast in operation, accurate and highly-efficient in detection result, allows needs of batch production and detection to be satisfied, and enables the processing efficiency of a pump body support to be effectively improved.
Description
Technical field
The utility model relates to the technical field that the endoporus right alignment detects, particularly a kind of two hole axiality detection devices.
Background technology
Pump housing support is the supporting and positioning device of the pump housing and main shaft, and like Fig. 1, pump housing support 1 comprises two endoporus; Wherein, hole A2 is used for supporting the location main shaft, and hole B3 is used for support and cooperates with the pump housing; Little because of this pump gap, if the right alignment of hole A2 and hole B3 is defective, it is steady to cause main shaft to rotate; Influencing the serviceable life of engine and pump, can cause this flow pump to turn round when serious, is very important and necessary to the hole A2 of pump housing support 1 and the detection of hole B3 right alignment therefore.
Current when detecting the right alignment in hole; Usually use revolving shaft collimation method, collimation method, coordinate method, wishbone method etc.; Mostly need special-purpose survey instrument when using the right alignment in these methods detection holes; And loaded down with trivial details, the consuming time length of measuring process, the requirement that can not satisfy batch process, detects has hindered the raising of production efficiency.
The utility model content
The purpose of the utility model is to overcome the shortcoming of prior art, and a kind of easy to use, two hole axiality detection devices that detection efficiency is high are provided.
The purpose of the utility model realizes through following technical scheme: a kind of two hole axiality detection devices; It comprises two positioning bodies and a coupling shaft; Described two positioning bodies are positioning body A and positioning body B, and positioning body A and positioning body B are disc, the external diameter of positioning body A with to survey the internal diameter size in the less hole of internal diameter in two holes identical; The external diameter of positioning body B is identical with the internal diameter size in survey another one hole in two holes; And all adopt clearance fit between positioning body A and positioning body B and the corresponding hole, an end of coupling shaft is connected with positioning body A, and the other end of coupling shaft is connected with positioning body B; The length of coupling shaft equates with the distance of being surveyed between two holes, and connects fixing positioning body A and the axial line of positioning body B overlaps by coupling shaft.
Described coupling shaft is the cylinder bodily form, and the axial line of the axial line of coupling shaft and positioning body A and positioning body B coincides.
The end face of described positioning body B is provided with handle.
The utlity model has following advantage:
The utility model is simple in structure, is easy to processing, and convenient to operation, testing result is accurate, efficient is high, can satisfy the demand of batch process, detection, can effectively improve the working (machining) efficiency of pump housing support.

Embodiment
Below in conjunction with accompanying drawing the utility model is done further description, but the protection domain of the utility model is not limited to the following stated:
As shown in Figure 2, a kind of two hole axiality detection devices, it comprises two positioning bodies and a coupling shaft 6; Described two positioning bodies are positioning body A4 and positioning body B5; Positioning body A4 and positioning body B5 are disc, and the external diameter of positioning body A4 is identical with the internal diameter size of pump housing support 1 hole A2, and the external diameter of positioning body B5 is identical with the internal diameter size of pump housing support 1 hole B3; All adopt clearance fit between positioning body A4 and the hole A2 and between positioning body B5 and the hole B3; One end of coupling shaft 6 is connected with positioning body A4, and the other end of coupling shaft 6 is connected with positioning body B5, and the length of coupling shaft 6 equates with distance between hole A2 and the hole B3; And connect fixing positioning body A4 and the axial line of positioning body B5 overlaps by coupling shaft 6; Coupling shaft 6 is the cylinder bodily form, and the axial line of the axial line of coupling shaft 6 and positioning body A4 and positioning body B5 coincides, and the end face of positioning body B5 is provided with handle 7.
The course of work of the utility model is following: positioning body A4 is penetrated pump housing support 1 from the hole B3 of pump housing support 1; And it is inner finally to penetrate hole A2; The outer wall of positioning body A4 closely contacts with the inwall of hole A2 each other, when coupling shaft 6 and the joint face of positioning body A4 are concordant with the inner face of hole A2, and the mated condition of the outer wall of detection and location body B5 and the inwall of hole B3; If the outer wall of positioning body B5 cooperates closely with the inwall of hole B3, then hole A2 and hole B3 right alignment are qualified; If can not closely cooperate between the inwall of the outer wall of positioning body B5 and hole B3, then hole A2 and hole B3 right alignment are defective.
