Abstract

The utility model relates to an efficient positioning tool for turning an outer circle. The efficient positioning tool comprises a positioning circular disc, wherein an annular positioning platform is arranged at the center of the circular disc; a cylinder is arranged at the center of the positioning platform; a thread hole is formed in the top face of the cylinder; the thread hole is internally provided with a bolt; the bolt is provided with a nut and a cover plate. The efficient positioning tool for turning the outer circle is simple in structure, flexible and convenient to use and high in clamping efficiency, and the machining precision is easy to guarantee.

Description

Efficient turning positioning tool

Technical field

The utility model relates to technical field of tooling clamps, relates in particular to the positioning fixture for workpiece being carried out to turning processing.

Background technology

Workpiece 1 as shown in Figure 1, its top is ring-type, bottom is the chassis with centre bore, chassis is connected by several bars with the cylindrical of top annulus, now need several bars described in it to carry out cylindrical car pin, but because the top clamping minister degree of workpiece 1 is shorter, use the higher realization of common scroll chuck, and machining accuracy also cannot guarantee.

Utility model content

The utility model, for above-mentioned shortcoming of the prior art, provides a kind of efficient turning positioning tool, and it is simple in structure, flexible and convenient to use, and clamping is simple, and machining accuracy is high.

The technical scheme that the utility model adopts is as follows:

Efficient turning positioning tool, comprises positioning disc, and disk central authorities are with ring-type positioning table, and positioning table center is cylinder, and the end face of cylinder and disk is threaded respectively hole and locating hole, and bolt is installed in screwed hole, and nut and cover plate are housed on bolt.

The utility model has the advantage of: the positioning table and the cylinder that match with workpiece polycrystalline substance are set on positioning disc and from workpiece bottom, it are carried out to effective location, bolt and cover plate are set simultaneously to be compressed it from the upper surface of workpiece, simple in structure, flexible and convenient to use, clamping is simple, and machining accuracy is high.

Accompanying drawing explanation

Fig. 1 is the structural representation of workpiece.

Fig. 2 is structural representation of the present utility model (lacking cover plate).

Fig. 3 is use state diagram of the present utility model.

The specific embodiment

Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described.

As shown in Figure 1 to Figure 3, the utility model comprises positioning disc 2, disk 2 central authorities are with ring-type positioning table 3, positioning table 3 is for the whole workpiece 1 of the bottom support from workpiece 1, and positioning table 3 centers are cylinder 4, and cylinder 4 coordinates location with the centre bore on workpiece 1 chassis, the end face of cylinder 4 is threaded hole 5, bolt 8 is installed in screwed hole 5, nut 6 and cover plate 7 are housed on bolt 8, by screwing nut 6, cover plate 7 can be pressed in the annular end face of workpiece 1;

Using method of the present utility model is as follows:

The first step, on the scroll chuck of positioning disc 2 fixing lathes;

Second step, by being placed on positioning table 3 of workpiece 1 chassis, makes the centre bore on workpiece 1 chassis coordinate with cylinder 4;

The 3rd step, passes bolt 8 cover plate 7 and puts in screwed hole 5;

The 4th step, screws the nut 6 on bolt 8, and it is pressed on cover plate 7, guarantees that cover plate 7 presses on the end face at workpiece 1 top;

The 5th step, carries out turning processing to workpiece 1.

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.
