The device comprises a round positioning disc, wherein a plurality of positioning holes and a plurality of positioning pins are formed in the positioning disc; a pair of short pressing block and a long pressing block are arranged on the positioning disc; an adjusting device is arranged below the long pressing block; the short pressing blocks and the long pressing block are fixedly connected with the positioning disc through bolts; and two counterweights are uniformly arranged on the positioning disc. The positioning device is simple in structure, simple and convenient to operate and high in positioning precision.
Description
Technical field
The utility model relates to technical field of tooling clamps, relates in particular to the frock clamp that the workpiece to the fine finishining endoporus positions.
Background technology
Processing to the hole generally is divided into first roughing, fine finishining again, all need workpiece is accurately located in process, especially fine finishining, higher to the positioning accuracy request of workpiece, workpiece 1 as shown in Figure 1, need to carry out fine finishining to its lip-deep installing hole 11, can adopt the mode of Vehicle Processing, but will guarantee its machining accuracy, at first must guarantee its positioning accuracy.
The utility model content
The utility model provides a kind of finish turning hole positioning device for the problems referred to above of the prior art, and it is simple in structure, and is easy and simple to handle, and the location machining accuracy is high.
The technical scheme that the utility model adopts is as follows:
The finish turning hole positioning device comprises circular positioning disk, on positioning disk with several locating holes and several alignment pins; A pair of short briquetting and a long briquetting are installed on positioning disk, are placed with adjusting device below long briquetting, short briquetting and long briquetting all are connected and fixed by bolt and positioning disk; Be evenly equipped with two balancing weights on positioning disk;
Further technical scheme is as follows:
The quantity of described locating hole and alignment pin is three;
Locating hole on described positioning disk is counterbore;
On described short briquetting and long briquetting all with elongated hole.
The utility model has the advantage of: locating hole is set on circular positioning disk is connected with lathe, the configuration balancing weight for the state of balance positioning disk, also with alignment pin and briquetting, positions compression to workpiece on the while positioning disk, guarantees the positioning accuracy of workpiece; Simple in structure, easy and simple to handle, the location machining accuracy is high.
Description of drawings
Fig. 1 is the stereogram after workpiece processing.
Fig. 2 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 depicted in figs. 1 and 2, the utility model comprises circular positioning disk 2, on positioning disk 2 with several locating holes 22 and several alignment pins 23, in the present embodiment, the quantity of locating hole 22 and alignment pin 23 is three, and locating hole 22 is counterbore, use bolt that positioning disk 2 and turntable of machine tool are connected and fixed, described bolt is in counterbore, and alignment pin 23 is distributed on leading section 11 both sides of workpiece 1 and the side-walls of workpiece 1, and workpiece 1 is carried out pre-determined bit; A pair of short briquetting 3 and a long briquetting 4 are installed on positioning disk 2, be placed with adjusting device 5 below long briquetting 4, short briquetting 3 and long briquetting 4 all are connected and fixed by bolt 6 and positioning disk 2, on short briquetting 3 and long briquetting 4 all with elongated hole, bolt 6 coordinates with described elongated hole, can be short according to the structural adjustment of workpiece 1 position of briquetting 3 and long briquetting 4; Also be evenly equipped with two balancing weights 21 on positioning disk 2, can play the effect of balance positioning disk 2 states, guarantee the positioning accuracy of positioning disk 2 workpiece 1 in rotation process;
Method of operating of the present utility model is as follows:
The first step is between three alignment pins 23, good with the location positioning of workpiece 1 on positioning disk 2 with workpiece 1 pre-determined bit;
Second step is pressed in short briquetting 3 and long briquetting 4 on workpiece 1, and adjusts the position of each briquetting, by bolt 6, workpiece 1 is compressed, and adjusts simultaneously adjusting device 5, makes long briquetting 4 be in level and is pressed on workpiece 1;
The 3rd step, use bolt that positioning disk 2 location are fixed on the rotating disk of lathe, described bolt is in counterbore on positioning disk 2;
The 4th step started lathe, made positioning disk 2 High Rotation Speeds, under balanced action, finish turning processing was carried out in the hole 11 on workpiece 1 at balancing weight 21.
Above description is to explanation of the present utility model, is not the restriction to utility model, and the utility model limited range within protection domain of the present utility model, can be done any type of modification referring to claim.
