Abstract

The invention relates to a positioning device for drilling. The positioning device comprises a positioning baseplate. A support platform is arranged at the center of the baseplate. A through hole is formed in the support platform. Support screws are arranged on the baseplate. A handle and a rubber pad are arranged on the outer circle and at the top of each screw respectively. A bolt is mounted in the through hole. A bushing plate with drill jigs is sleeved on the bolt. A nut and a gasket mounted on the bolt are pressed on the bushing plate. The positioning device is simple in structure, flexible and convenient to use, simple to mount and clamp and high in processing accuracy.

Description

Drilling-hole positioning device

Technical field

The present invention relates to technical field of tooling clamps, relate in particular to for workpiece being carried out to the positioning fixture of Drilling operation.

Background technology

For the more complicated workpiece of structure, it is being positioned and is adding man-hour, use plain clamp to acquire a certain degree of difficulty to its location, especially to guarantee machining accuracy, must use special-purpose frock just can meet the demands, and frock must be easy to use, clamping efficiency is high, can guarantee its machining accuracy again simultaneously.

Summary of the invention

The present invention is directed to above-mentioned shortcoming of the prior art, a kind of drilling-hole positioning device is provided, it is simple in structure, flexible and convenient to use, and clamping efficiency is high, and machining accuracy is high.

The technical solution adopted in the present invention is as follows:

Drilling-hole positioning device, comprises positioning chassis, and chassis central authorities are with brace table, and on brace table, with through hole, on chassis, also with studdle, the cylindrical of screw rod and top are respectively with handle and rubber blanket; Bolt is housed in through hole, with the bushing plate of drill jig, is placed on bolt, on bolt, nut is installed and pad is pressed on bushing plate.

The invention has the advantages that: according to the structure of workpiece, the resilient rubber sheet gasket of tool for mounting on the studdle on chassis, workpiece is played to certain Balanceregulation, and studdle can regulate height, guarantees that whether the location of workpiece is accurate, bushing plate is pressed on workpiece, directly can to workpiece, carry out Drilling operation by drill jig, simple in structure, flexible and convenient to use, clamping efficiency is high, and machining accuracy is high.

Accompanying drawing explanation

Fig. 1 and Fig. 2 are structural representation 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 to Figure 2, the present invention includes positioning chassis 1, chassis 1 central authorities are with brace table 2, 2 pairs of workpiece main body section of brace table support, on brace table 2 with through hole 3, on chassis 1 also with studdle 4, 4 pairs of workpiece of studdle play the effect of supplemental support, the cylindrical of studdle 4 and top are respectively with handle 5 and rubber blanket 6, rotary handle 5 can regulate the height of studdle 4, and then the poised state of adjusting workpiece, because the structure of workpiece is more complicated, rubber blanket 6 can play the fine setting to workpiece, and can avoid rigidity contact, prevent the surface quality of workpiece to cause damage, bolt 9 is housed in through hole 3, with the bushing plate 7 of drill jig 8, is placed on bolt 9, nut 10 and pad 11 are installed on bolt 9 and are pressed on bushing plate 7, during processing location, bushing plate 7 is pressed on workpiece, by drill jig 8, completes the Drilling operation to workpiece,

Using method of the present invention is as follows:

The first step, is fixed on chassis 1 on operating desk;

Second step, is placed in workpiece on brace table 2, regulates the height of studdle 4 to supporting from workpiece bottom;

The 3rd step, installing drill template 7 is pressed on workpiece in advance;

The 4th step, mounting nuts 10 and pad 11 on bolt 9, and screw nut 10 and press on bushing plate 7;

The 5th step, according to the positioning states to workpiece, fine setting studdle 4, makes the location of workpiece more accurate;

The 6th step, carries out Drilling operation by 8 pairs of workpiece of drill jig.

More than describing is explanation of the invention, is not the restriction to invention, and limited range of the present invention, referring to claim, within protection scope of the present invention, can be done any type of modification.

Claims (1)

1. drilling-hole positioning device, comprise positioning chassis (1), it is characterized in that: chassis (1) central authorities are with brace table (2), brace table (2) is upper with through hole (3), on chassis (1), also with studdle (4), the cylindrical of studdle (4) and top are respectively with handle (5) and rubber blanket (6); Bolt (9) is housed in through hole (3), with the bushing plate (7) of drill jig (8), is placed on bolt (9) upper, nut (10) is installed on bolt (9) and pad (11) is pressed on bushing plate (7).
