Abstract
The invention relates to a device for machining and positioning a fine hole of a bolt. The device comprises a positioning plate, wherein two weighing blocks, a positioning pin and positioning holes are arranged on the positioning plate; a positioning base is mounted on the positioning plate in a vertical direction of the positioning pin; a first V-shaped groove is arranged on the positioning base; a pressing block is mounted on the positioning base; a second V-shaped groove is arranged on the pressing block; the two weighing blocks are symmetrically arranged relatively to the positioning pin; the three positioning holes are uniformly distributed; and distances from the positioning holes to the center of the positioning plate are the same. The device for machining and positioning the fine hole of the bolt provided by the invention has the advantages of simple structure, simplicity and convenience in operation, and high machining precision.
Description
Technical field
The present invention relates to technical field of tooling clamps, relate 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 in that it is positioned, if Fixture designing is unreasonable, relatively rotating of screw rod and frock occurs very easily, affects machining accuracy.
Summary of the invention
The present invention is directed to the problems referred to above of the prior art, the smart hole of a kind of bolt processing and positioning device is provided, it is simple in structure, and is easy and simple to handle, and machining accuracy is high.
The technical solution adopted in the present invention is as follows:
The smart hole of bolt processing and positioning device comprises positioning disk, on the positioning disk with two balancing weights, alignment pin and locating holes, direction vertical with alignment pin on the positioning disk is equipped with positioning seat, with the first V-shaped groove, briquetting is installed on the positioning seat on the positioning seat, on the briquetting with the second V-shaped groove; Two balancing weights are symmetrical arranged about alignment pin; Locating hole is uniform to be that three and each locating hole are 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 invention has the advantages that: at positioning disk balancing weight is set, the balance when being conducive to the positioning disk rotation guarantees machining accuracy; Be provided with the positioning seat of V-shaped groove on the 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 the positioning disk; The present invention 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 invention.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
As shown in Figure 1, the present invention includes positioning disk 1, on the positioning disk 1 with two balancing weights 2, alignment pin 3 and locating hole 4; Direction vertical with alignment pin 3 on the positioning disk 1 is equipped with positioning seat 5, with the first V-shaped groove, briquetting 6 is installed on the positioning seat 5 on the positioning seat 5, and with the second V-shaped groove, described the first V-shaped groove matches with the second V-shaped groove workpiece 8 is compressed on the briquetting 6; 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 to be that three and each locating hole 4 are 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 even, 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.
More than describing is explanation of the invention, is not that limited range of the present invention within protection scope of the present invention, can be done any type of modification referring to claim to the restriction of invention.
