Abstract
The utility model provides a double-positioning center, which comprises an offset runout detection instrument and a center body fixedly connected with the offset runout detection instrument. A movable center is arranged on the offset runout detection instrument, a center shaft is arranged in the center body, an elastic body is sleeved on the tail portion of the center shaft, and a center is arranged in the head portion of the center shaft. The double-positioning center has the advantages that via said structure, the movable center of the offset runout detection instrument and the center of the center body can respectively directly act on the end surface of a workpiece, so that the distance between the two centers is the diameter of the workpiece; due to telescopic effect of a spring, the double-positioning center is suitable for measurement of molded surfaces in different diameters and can abut tightly against the molded surfaces, a bearing is assembled to enable the workpiece to rotate freely, and a positioning sleeve is matched and assembled with inner holes of the bearing to play the role of spacing, so that the diameter and length of the molded surface of the workpiece can be accurately and rapidly measured; and the double-positioning center is simple in operation and low in production cost.
Description
Technical field
It is top that the utility model relates to a kind of two location.
Background technology
At present, when measurement has the workpiece of profile, the workpiece that for example has tapering, curved surface etc. generally all uses survey instruments such as slide calliper rule, milscale, but its external diameter, length are difficult to conventional measurer detection, it is not high namely to enable accuracy in detection yet, have only with projector and universal tool-measuring microscope and detect, just can accurately detect, but complicated operation, inefficiency, the cost height.
The utility model content
The purpose of this utility model provides that a kind of tailstock location is top, and it can measure profile diameter and the length dimension with profile workpiece accurately and rapidly, and simple to operate, production cost is low.
The technical solution of the utility model is achieved in that a kind of two location is top, comprise beat instrument and the top body of fixedlying connected with it, described beat instrument is provided with mobile top, described top body inside is provided with tail spindle, described tail spindle afterbody is arranged with elastic body, and described tail spindle head is provided with top.
As preferably, the inside of described top body is that hollow structure and top body head are provided with locating sleeve.
As preferably, described locating sleeve inwall is provided with bearing.
As preferably, described elastic body is spring.
The beneficial effects of the utility model are: after adopting said structure, because top on the top and top body of movement of beat instrument directly acts on the workpiece end face respectively, so two distances between top are exactly the diameter of workpiece, again because the scalable effect of spring, so be applicable to the measurement of various profile diameter and can hold out against profile, running in bearings can make the workpiece rotation freely, locating sleeve cooperates with brearing bore and loads the back and play position-limiting action, can be accurate, measure profile diameter and the length dimension with profile workpiece fast, simple to operate, production cost is low.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment technical scheme, the accompanying drawing of required use is done to introduce simply in will describing embodiment below, apparently, accompanying drawing in describing below only is that this practicality is in order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below, apparently, accompanying drawing in describing below only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is structural representation of the present utility model;
Fig. 2 uses view for the utility model.
Embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
As depicted in figs. 1 and 2, a kind of two location are top, comprise beat instrument 10 and the top body 8 of fixedlying connected with it, described beat instrument 10 is provided with mobile top 7, described top body 8 inside are provided with tail spindle 3, and described tail spindle 3 afterbodys are arranged with elastic body 2, and described tail spindle 3 heads are provided with top 6.In the present embodiment, the inside of described top body 8 is that hollow structure and top body 8 heads are provided with locating sleeve 5, and described locating sleeve 5 inwalls are provided with bearing 4, and described elastic body 2 is spring.
In use, top body 8 is installed in the stiff end of beat instrument 10 tailstocks, top 6 of top body 8 is withstood on the fabrication hole of workpiece datum end face, the movement of beat instrument 10 top 7 withstands on the fabrication hole of other end, move by mobile top 7 and to exert pressure, workpiece reference field and apical pore are close to simultaneously, thereby have realized the purpose of apical pore and reference field " two location ", as long as rotational workpieces just can directly be read the numerical value of measure portion by height gauge 9.Because top 6 on the movement top 7 of beat instrument 10 and the top body 8 directly acts on the workpiece end face respectively, so two distances between top are exactly the diameter of workpiece, again because the scalable effect of elastic body 2, so be applicable to the measurement of various profile diameter and can hold out against profile, running in bearings 4 can make the workpiece rotation freely, locating sleeve 5 cooperates with bearing 4 endoporus and loads the back and play position-limiting action, can measure profile diameter and length dimension with profile workpiece accurately and rapidly, simple to operate, production cost is low.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
