Abstract

The utility model relates to a bolt fine hole processing and positioning device, which comprises a positioning disk, wherein the positioning disk is provided with two balancing weights, a positioning pin and positioning holes; a positioning base is arranged on the positioning disk along a direction which is vertical to the positioning pin; the positioning base is provided with a first V-shaped groove; pressure blocks are arranged on the positioning base; the pressure blocks are provided with second V-shaped grooves; the two balancing weights are arranged symmetrically relative to the positioning pin; and three positioning holes are uniformly distributed, and are of the same distances away from the center of the positioning disk. The positioning device has the advantages of simple structure, easiness and convenience in operating and high processing accuracy.

Description

Bolt essence hole processing and positioning device

Technical field

The utility model relates to technical field of tooling clamps, relates in particular to a kind of positioner of being holed in the bolt end.

Background technology

Bolt contains screw rod and bolt head and forms, if its bolt head is carried out Drilling operation, because screw rod is cylinder, adds man-hour it is positioned, if Fixture designing is unreasonable, relatively rotating of screw rod and frock occurs very easily, affects machining accuracy.

The utility model content

The utility model is for the problems referred to above of the prior art, and a kind of bolt essence hole processing and positioning device is provided, and it is simple in structure, and is easy and simple to handle, and machining accuracy is high.

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

Bolt essence hole processing and positioning device comprises positioning disk, on positioning disk with two balancing weights, alignment pin and locating holes, direction vertical with alignment pin on positioning disk is equipped with positioning seat, with the first V-shaped groove, briquetting is installed on positioning seat on positioning seat, on briquetting with the second V-shaped groove; Two balancing weights are symmetrical arranged about alignment pin; Locating hole is uniform, and to be three and each locating hole identical to the distance at positioning disk center;

Further technical scheme is as follows:

Described briquetting is two and all is connected with bolt and positioning seat.

The utility model has the advantage of: balancing weight is set on positioning disk, and the balance when being conducive to the positioning disk rotation guarantees machining accuracy; Be provided with the positioning seat of V-shaped groove on positioning disk, positioning seat matches with briquetting with V-shaped groove workpiece is compressed, and also with alignment pin, is used for workpiece is carried out axial location on positioning disk; The utility model is simple in structure, and is easy and simple to handle, and machining accuracy is high.

Description of drawings

Fig. 1 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, the utility model comprises positioning disk 1, on positioning disk 1 with two balancing weights 2, alignment pin 3 and locating hole 4; Direction vertical with alignment pin 3 on positioning disk 1 is equipped with positioning seat 5, with the first V-shaped groove, briquetting 6 is installed on positioning seat 5 on positioning seat 5, and on briquetting 6, with the second V-shaped groove, described the first V-shaped groove matches with the second V-shaped groove workpiece 8 is compressed; Briquetting 6 is two and is connected by bolt 7 and positioning seat 5; Two balancing weights 2 are symmetrical arranged about alignment pin 3, are conducive to add the balance of positioning disk 1 rotation in man-hour; Locating hole 4 is uniform, and to be three and each locating hole 4 identical to the distance at positioning disk 1 center, locating hole 4 is used for positioning disk 1 is navigated to the chuck of lathe, guarantee that positioning disk 1 is stressed evenly, can improve the positioning accuracy of positioning disk 1, add man-hour, alignment pin 3 is used for axial location is carried out in the end of workpiece 8, and then guarantees the machining accuracy of the boring 81 of workpiece 8.

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.
