The existing measurement cubing short cylindrical shape measurement dish equally large with dead eye 11 that be design, a hole coaxial with cylindrical of middle processing, sounding rod 12 and Kong Cheng little clearance fit, dial gauge is adsorbed on sounding rod and is measured by magnetic stand.Because the specification of the pump housing 10 is more, make many special measurement dishes, both uneconomical, bring many troubles to production management.
Existing measuring method is as shown in Figure 3: two special measurement dishes 14 are placed on bearings at both ends hole 11, and sounding rod 12 passes from interstitial hole, and magnetic stand 13 is adsorbed on sounding rod 12 and measures.Because measurement dish 14 can not be just the same with dead eye 11 diameter dimensions, so this measurement exists positioning error, affect measuring accuracy.
Utility model content
For the problems referred to above, fundamental purpose of the present utility model is to provide a kind of can detect multiple pump housing right alignment, reduces the measurement cubing of the geometric error of testing cost.
The utility model solves above-mentioned technical matters by following technical proposals: a kind of geometric error is measured cubing, and described geometric error is measured cubing and comprised following mechanism: clamp body, two locating pieces, trip bolt and adjustment screw rods.
Clamp body: clamp body two ends are provided with groove, two locating pieces are arranged on respectively in the groove at two ends, and groove upper end all has the threaded hole that trip bolt is installed, and the centre of clamp body is provided with interstitial hole, clamp body two ends are provided with locating surface, and the center line of described locating surface and interstitial hole is in same plane.
Locating piece comprises two parts, is respectively and is adjacent to part on the locating piece that under the locating piece of workpiece datum hole that needs to detect, part and locating clip are concrete, and under described locating piece, part is partly vertical with on locating piece, and described locating piece top is divided and is provided with threaded hole.
Locating piece is contained in the groove of clamp body, adopts an adjustment screw rod to be screwed into the threaded hole of locating piece, rotates and adjusts screw rod, and locating piece moves inwards or outwards.
In specific embodiment of the utility model, described adjustment screw rod is adjusted the hexahedron of bolt rotary for convenience of adjustment away from one end of clamp body.
In specific embodiment of the utility model, described trip bolt adjusts away from locating piece one end the hexahedron that trip bolt rotates for convenience.
The novel positive progressive effect of this use is: the geometric error that the utility model provides is measured inspection and had the following advantages: the utility model adopts a set of cubing can carry out the pump housing coaxality measurement of all specifications, has saved testing cost.Can adjust to pump housing dead eye coaxially due to the cubing axle of cubing, so reduced measuring error, improve accuracy of detection.

Embodiment
Provide the utility model preferred embodiment below in conjunction with accompanying drawing, to describe the technical solution of the utility model in detail.
The geometric error that the utility model provides is measured cubing and is comprised as lower member: clamp body 1, locating piece 2, trip bolt 3, adjustment screw rod 4 etc.
Fig. 4 is the structural representation of clamp body in the utility model, and Fig. 5 is the structural representation of the C-C direction of Fig. 4, and Fig. 6 is the structural representation of the B-B direction of Fig. 4.As Figure 4-Figure 6: there is groove 101 at clamp body 1 two ends, two locating pieces 2 are arranged on respectively in the groove 101 at two ends, groove 101 upper ends all have the threaded hole 102 that trip bolt 3 is installed, the centre of clamp body 1 is provided with interstitial hole 103, clamp body 1 two ends are provided with locating surface 104, and the center line of locating surface 104 and interstitial hole 103 is in same plane.
