The high-precision drilling fixture for the cylinder workpiece comprises a bottom plate, wherein the bottom plate is successively and fixedly connected with one pair of regulation seats, a jig drilling seat and a supporting seat from left to right; the side walls of the regulation seats are provided with chutes; a V-shaped supporting block is installed in the chutes; a jack is installed below the V-shaped supporting block on the bottom plate; the jig drilling seat is provided with a horizontal positioning hole and a vertical drilling jig; the supporting seat is vertically and fixedly connected with a screw. The high-precision drilling fixture for the cylinder workpiece, which is disclosed by the utility model, has the advantages of simple structure, flexibility and convenience in use, simpleness in clamping and high processing precision.

Description

Cylinder workpiece high-precision borehole fixture

Technical field

The utility model relates to technical field of tooling clamps, relates in particular to the fixture that cylinder Workpiece boring is positioned.

Background technology

On cylinder workpiece, punch, although be more conventional technique, use common positioning tool to realize, but the workpiece of having relatively high expectations for borehole accuracy, must use accurate positioning tool to realize, otherwise borehole accuracy is undesirable, finally cause product rejection, increased the production cost of enterprise.

Utility model content

The utility model, for above-mentioned shortcoming of the prior art, provides a kind of cylinder workpiece high-precision borehole fixture, and it is simple in structure, flexible and convenient to use, and clamping efficiency is high, and machining accuracy is high.

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

Cylinder workpiece high-precision borehole fixture, comprises base plate; A pair of adjustment seat, jig seat and supporting seat from left to right are successively connected on base plate; Adjustment seat sidewall, with chute, is equipped with V-arrangement back-up block in described chute, the below that is positioned at V-arrangement back-up block on base plate is provided with jack; In jig seat with the drill jig of a horizontal location hole and a vertical direction; Screw rod is vertically connected on supporting seat.

The utility model has the advantage of: the both sides in jig seat arrange respectively adjustment seat and supporting seat, adjustment seat is vertically positioning workpiece, screw rod is installed on supporting seat, can position in the horizontal direction workpiece, and can accurately regulate workpiece displacement in the horizontal direction, simple in structure, flexible and convenient to use, clamping efficiency is high, and machining accuracy is high.

Accompanying drawing explanation

Fig. 1 is structural representation 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 base plate 1; A pair of adjustment seat 7, jig seat 4 and supporting seat 2 from left to right are successively connected on base plate 1; Adjustment seat 7 sidewalls are with chute, V-arrangement back-up block 8 is housed in described chute, back-up block 8 can slide up and down along described chute, the below that is positioned at V-arrangement back-up block 8 on base plate 1 is provided with jack 9, regulate jack 9 adjustable support pieces 8 at vertical height, and then the workpiece on V-arrangement back-up block 8 is carried out to vertical position adjustments; In jig seat 4, with the drill jig 6 of a horizontal location hole 5 and a vertical direction, during location, workpiece is inserted in locating hole 5, by drill jig 6, workpiece is carried out to perforation processing; The screw rod 3 that is vertically connected on supporting seat 2, the rectifying locating hole 5 of screw rod 3, can carry out workpiece spacing, simultaneously can rotary screw 3, make it withstand workpiece, regulate the position of workpiece in locating hole 5;

Using method of the present utility model is as follows:

The first step, is fixed on base plate 1 on operating desk;

Second step, is placed in cylinder workpiece on V-arrangement back-up block 8, and inserts in locating hole 5, makes the end of workpiece withstand on the end of screw rod 3;

The 3rd step, rotary screw 3, makes workpiece in the horizontal direction 9 along locating hole 5 axial translations;

The 4th step, confirms, after the location of workpiece, by drill jig 6, it to be carried out to Drilling operation.

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.
