CN201397118Y - Eccentric check tool - Google Patents

Abstract

The utility model relates to an eccentric check tool, which mainly solves the problems of the prior eccentric part that the measurement is inaccurate, and the accuracy of the installation position ofan eccentric locking collar is low. The eccentric check tool is characterized in that a positioning shaft (6) is connected with the lower part of a base (5), a through-hole clamping head (2) is transversely fixed at the upper part of the base (5), and a dial indicator (4) is clamped on the clamping head (2) through a through hole. The eccentric check tool has the characteristic that the excursionmeasuring of the eccentric part and the eccentric locking collar is accurate and convenient.

Description

A kind of eccentric cubing

Technical field:

The utility model belongs to a kind of testing tool of field of machining, relates in particular to a kind of eccentric cubing.

Background technology:

In machining, meet the part of some eccentric bent covers and so on through regular meeting, in process, need the side-play amount in frequent measured hole and hole, process qualified part with assurance.On lathe, be difficult to generally speaking directly measure side-play amount, though some measuring methods are arranged, very inaccurate yet, because measurement is inaccurate, will cause the part of processing defective, wasted material, artificial.In addition in some assembling processes, also need the cover of two different-diameters is mounted to the form of eccentric bushing, side-play amount has requirement, and the height of skew also has status requirement, this in the past situation is assembled with excentric shaft when assembling, but the skew high and low position error of installing is big, does not guarantee accuracy requirement.

The utility model content:

Measure inaccurate, the low deficiency of eccentric bushing installation site precision in order to overcome existing eccentric element, the utility model provides a kind of eccentric cubing, and this off-centre cubing has that the side-play amount of eccentric element and eccentric bushing is measured accurately, characteristics easily.

The technical solution of the utility model is: a kind of eccentric cubing, comprise cubing body and coupled base, handle, and the base bottom connects locating shaft, and base top fixed lateral has the dop of through hole, and dial gauge passes through hole and is stuck on the dop.

Above-mentioned handle can be fixed on the base, also can be fixed on the cubing body.

The utlity model has following beneficial effect: owing to take such scheme, locating shaft is arranged at the base bottom, dop is arranged at top, and is fixed with dial gauge on the dop, when measuring the side-play amount of part, only need locating shaft is directly cooperated with datum hole, perhaps cooperate with datum hole, dial gauge is withstood on round inwall, turning handle by the spacer shell (increasing the versatility of cubing) that matches with locating shaft, make the cubing body rotate a week, can measure the side-play amount of part.This off-centre cubing is simple in structure, easy to use, measures accurately, can effectively reduce the error that part occurs in process, increases work efficiency, and has also solved the installation accuracy problem of eccentric bushing in the assembling process simultaneously, has improved the product total quality.

Description of drawings:

Accompanying drawing 1 is a structural representation of the present utility model;

1-cubing body among the figure, 2-dop, 3-handle, 4-dial gauge, 5-base, 6-locating shaft.

Embodiment:

The utility model is described in further detail below in conjunction with accompanying drawing:

By Figure 1 and Figure 2, a kind of eccentric cubing, comprise cubing body 1 and coupled base 5, base 5 bottoms connect locating shaft 6, cubing body 1, base 5, locating shaft 6 can weld together, and also can directly be processed into one, and base 5 top fixed lateral have the dop 2 of through hole, dial gauge 4 passes through hole and is stuck on the dop 2, and the end of dial gauge 4 is outside.Handle 3 can be fixed on the base 5, also can be fixed on the cubing body 1, is handled easily, two handle 3 positioned opposite.

When detecting eccentric element, be benchmark, backstay 6 is mated with the hole in piece part that processes, part at different size, can adopt the different cubing of locating shaft 6 sizes, perhaps use the corresponding spacer shell of size, spacer shell is enclosed within on the locating shaft 6 exactly, earlier the spacer shell outside is cooperated with hole in piece part, dial gauge 4 is stuck in the through hole of dop 2, turning handle 3 makes 360 ° of cubing unitary rotation again, according to the reading of dial gauge 4, can measure side-play amount.When assembling, also be that locating shaft 6 (or spacer shell) is matched with datum hole, survey the maximum offset of another part, determine its direction position, finish matching requirements.This off-centre cubing is simple in structure, easy to use, measures accurately, can effectively reduce the error that part occurs in process, increases work efficiency, and has also solved the installation accuracy problem of eccentric bushing in the assembling process simultaneously, has improved the product total quality.

Claims (3)

1, a kind of eccentric cubing, comprise cubing body (1) and coupled base (5), handle (3), it is characterized in that: base (5) bottom connects locating shaft (6), and base (5) top fixed lateral has the dop (2) of through hole, and dial gauge (4) passes through hole and is stuck on the dop (2).

2, eccentric cubing according to claim 1 is characterized in that: handle (3) is fixed on the base (5).

3, eccentric cubing according to claim 1 is characterized in that: handle (3) is fixed on the cubing body (1).
