Abstract
The utility model relates to a positioning tool used for inner circle lathing. The positioning tool comprises a casing, wherein the upper part of the base is connected with a positioning seat, and the exterior of the positioning seat is sleeved with a positioning cover; a plurality of arc-shaped lugs are distributed inside the positioning seat, a polygonal hole is among all arc-shaped lugs, and a spring pin is arranged on at least one arc-shaped lug. The positioning tool provided by the utility model has a simple structure and is simple and convenient to mount, the involving of the spring pin ensures the stability of parts inserted into the positioning seat, the polygonal hole is in interference fit with the polygonal base of the parts, locking is performed through the positioning cover and a fastening part, stability and accuracy during lathing of the parts can be ensured, the concentricity is ensured, and the processing quality and the processing efficiency are improved.
Description
Technical field
The utility model relates to frock, especially a kind of positioning tool for inner circle Vehicle Processing.
Background technology
At present in order to process various rotary surfaces, inside and outside circle cylinder, inner headed face, taper seat and the shaping surface of revolution all need to use Vehicle Processing, for Vehicle Processing, in order to guarantee the concentricity of position to be processed and part, prerequisite is the position stability that will guarantee part, so in the urgent need to designing a kind of frock with located higher stability.
Utility model content
The applicant, for above-mentioned existing issue, is studied improvement, and a kind of positioning tool for inner circle Vehicle Processing is provided, and has position stability good, the advantage that concentricity and machining accuracy are high.
The technical scheme that the utility model adopts is as follows:
For a positioning tool for inner circle Vehicle Processing, comprise base, on the top of base, connect positioning seat, the outer cover dress locating cover of described positioning seat; Multiple arc bumps are arranged in the inside of described positioning seat, between each arc bump, form polygonal hole, at least on an arc bump, resilient key are set.
Its further technical scheme is:
Described base, positioning seat and locating cover are circle;
On locating cover, have circular through hole, described circular through hole and locating cover, in the same center of circle, are positioned at the two ends of described circular through hole, at described locating cover, securing member are also set.
The beneficial effects of the utility model are as follows:
The utility model is simple in structure, simple installation, resilient key relate to fraction part in the solid stability embedding during positioning seat, the polygon base matched in clearance of polygonal hole and part simultaneously, and lock by locating cover and securing member, guarantee stability and the accuracy of part when Vehicle Processing, guaranteed concentricity, improved crudy and working (machining) efficiency.
Accompanying drawing explanation
Fig. 1 is blast structural representation of the present utility model.
Fig. 2 is partial structurtes schematic diagram of the present utility model after Assembly part.
Fig. 3 is perspective view of the present utility model.
Wherein: 1, base; 2, positioning seat; 3, locating cover; 201, arc bump; 202, resilient key; 203, polygonal hole; 301, securing member; 302, circular through hole; 4, polygon base; 401, interior circular hole; 402, round boss.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described.
As shown in Figure 1, a kind of positioning tool for inner circle Vehicle Processing comprises base 1, at the top of base 1 welding positioning seat 2, the outer cover dress locating cover 3 of positioning seat 2, on locating cover 3, have circular through hole 302, circular through hole 302 in the same center of circle, is positioned at the two ends of circular through hole 302 with locating cover 3, at locating cover 3, securing member 301 is also set.Multiple arc bumps 201 are arranged in the inside (in the utility model, arc bump 201 is 4) of positioning seat 2, between each arc bump 201, form polygonal hole 203, at least on an arc bump 201, resilient key 202 are set.Base 1, positioning seat 2 and locating cover 3 are circle.
The concrete assembling process of the utility model and part is as follows:
As shown in Figure 2, part to be processed comprises polygon base 4, at four jiaos of places of polygon base 4, installing hole is set, and the middle part that is positioned at described polygon base 4 arranges round boss 402, has the interior circular hole 401 that concentric is arranged in round boss 402.By polygon base 4 matched in clearance of part to be processed in the polygonal hole 203 of positioning seat 2, resilient key 202 contacts backward interior contraction with polygon base 4, when shape changeable base 4 stretch into completely polygonal hole 203 interior after, resilient key 202 is stretched out and is propped up the wall of polygon base 4 by elastic force, guaranteed the assembling strong degree of positioning seat 2 with part to be processed.In order to guarantee that part adds the solid stability in man-hour, as shown in Figure 3, locating cover is sleeved on to the periphery of positioning seat 2, the installing hole that four jiaos of places of the polygon base 4 by securing member 301 and part to be processed arrange is simultaneously locked, and has guaranteed to add the stability of part in man-hour.
More than describing is to explanation of the present utility model, is not the restriction to utility model, and the utility model limited range, referring to claim, within protection domain of the present utility model, can be done any type of modification.
