Abstract

The utility model discloses a multi-journal measuring device. The device comprises a locating measuring head and a floating measuring head which are respectively connected with a pneumatic measuring instrument. Matching cushion blocks are arranged on a plane plate in line with intervals. The rod part of the locating measuring head is coordinated with the cushion block at the middle section. The centers of adjacent locating measuring head are regulated to be at the same level, which is taken as measuring basis. The rod parts of the floating measuring head are respectively sleeved by a spherical washer and a spring which are coordinated with the cushion blocks to form a flexible structure which automatically support in place. When in practical measurement, the measured journal is supported by the floating measuring head at first; and then the measured journal is pressed down and the middle section of the journal is closely leaned on the locating measuring head. The pneumatic measuring instrument is used for accurately measuring and setting the practical deviation value of the journal. The multi-journal measuring device is of convenient and quick measurement, which is especially suitable for the measuring tool of mass production.

Description

Multi-journal measuring device

Technical field

The present invention relates to a kind of measurer of measuring length, particularly a kind of measurement mechanism of measuring coaxial each section axle journal diameter simultaneously.

Background technology

Axle is the fundamental parts in the plant equipment.The axle of conventional structure all is provided with more than two the axle journal that cooperates with accessory mutually, and for the size detection of axle journal, prior art adopts general length measurer can accurately measure each section axle journal physical size respectively.But prior art only is adapted at single-piece production or the small serial production stage uses, and surveys for the multiaxis neck repacking of producing in enormous quantities, adopts the prior art detection efficiency low, can not satisfy the requirement of batch detection.

Summary of the invention

The present invention is primarily aimed at prior art low problem of detection efficiency when measuring the multiaxis neck, propose a kind of simple in structure, measure accurately, value shows many journal shaft measurement mechanism of tested each axle journal diameter simultaneously.

The present invention is achieved through the following technical solutions technical goal.

Multi-journal measuring device, it comprises location amount head and the amount of floating head that is connected with pneumatic measuring instrument respectively, and the cushion block that matches becomes same linear interval to arrange on flat board.Described location amount head cooperates with the cushion block that is positioned at the stage casing with bar portion, and the center of setting up adjacent positioned amount head is contour.Its improvements are: the bar portion of described amount of floating head is suit ball ring and spring respectively, cooperates the flexible structure that constitutes the autofitting supporting with the cushion block that is located at two avris.

In the said structure, the carrying plane of amount of floating head and location amount head is V-arrangement, and the centre-height of amount of floating head under free state is than the high 5～10mm of centre-height of location amount head.Spring shaft is to the 1～2kgf of elastic force greater than measured axis weight.

The present invention compared with prior art has following good effect:

1, simple in structure, easy to manufacture;

2, multiaxis neck synchro measure, the efficiency of measurement height is fit to the detection apparatus that work is produced many journal shaft in enormous quantities;

3, from supporting flexible structure in place, accurate positioning, it is convenient to measure.

Description of drawings

Accompanying drawing is the utility model structural representation.

Embodiment

Below with reference to the accompanying drawings and in conjunction with the embodiments, the utility model is described in further detail.

Multi-journal measuring device shown in the accompanying drawing is the embodiment that synchro measure is provided with 4 axle journal bevel gear shafts, it comprises the location amount that is connected with pneumatic measuring instrument 2 respectively 4,5 and amount of

floating head

3,6, and the

cushion block

8,10,11 that matches and 12 being aligned on dull and stereotyped 9 is spaced.Described location amount 4,5 cooperates with the

cushion block

10,11 that is positioned at the stage casing respectively with bar portion, and it is contour to set up both centers, and to measure 4,5 with the location be measuring basis.The bar portion of described amount of

floating head

3,6 is suit ball ring 13 and spring 7 respectively, cooperates the flexible structure that constitutes the autofitting supporting with the

cushion block

8,12 that is located at two avris.During actual the use, measured axis 1 with the direct frame of two ends axle journal on the V-arrangement carrying plane of amount of

floating head

3,6, in addition two axle journal correspondences are suspended on the V-arrangement carrying plane of location amount 4,5, the operative employee is by the manually downward application of force 1～2kgf, the V-arrangement carrying plane that makes two axle journals and the location amount 4,5 in the middle of being positioned at is by reality, amount of

floating head

3,6 is under ball ring 13 effects in the case, and a same measuring basis of 4,5 maintenances is measured in automatic and location.The 1:50000 pneumatic measuring instrument of using in the present embodiment 2, the synchronous actual deviation value that accurately detects 4 axle journals.The utility model is measured convenient, fast, is fit to do to detect the measurer of producing many journal shaft in enormous quantities.
