Abstract

The utility model relates to an efficient positioning clamp for drilling. The efficient positioning clamp for drilling comprises a base; a rectangular positioning block is arranged on the base; the top of the positioning block is provided with a threaded hole and a plurality of positioning pins; a T-shaped slot is arranged at the side surface of the positioning block; through holes are formed in the inside wall of the T-shaped slot; an upper clamping block and a lower clamping block are arranged in the T-shaped slot and are respectively provided with a semicircular slot at the side wall; the two semicircular slots form a circle hole; one end of each positioning pin extends into the T-shaped slot; the other end of each positioning pin is abutted against a pressure plate of which the edge is provided with a step; the step is matched with the edge of the positioning block; the pressure plate is fixedly connected with the positioning block by a compressing screw; a plurality of screws are arranged at the side wall of the positioning block; the end part of each screw is abutted against the corresponding positioning pin. The efficient positioning clamp for drilling is simple in structure, flexible and convenient to use, simple in clamping and high in machining precision.

Description

Efficient drilling positioning fixture

Technical field

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

Background technology

Bolt 1 as shown in Figure 1, now need to process in its end an aperture, because its size is less, 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.

Utility model content

The utility model, for above-mentioned shortcoming of the prior art, provides a kind of efficient drilling positioning 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:

Efficient drilling positioning fixture, comprise base, rectangle locating piece is set on base, the top of locating piece is threaded hole and several alignment pin, the sidewall of locating piece is with T-slot, and the madial wall of T-slot, with through hole, is equipped with fixture block and lower fixture block in T-slot, upper fixture block and lower fixture block sidewall are all with semi-circular groove, and described two half slots form a circular hole; Alignment pin one end is stretched in T-slot, and the other end withstands pressing plate, and platen edge is with step, the edge mate of step and locating piece, and pressing plate is connected by housing screw and locating piece, and the sidewall of locating piece is positioned at installs several screws, and the end of screw props up alignment pin.

The utility model has the advantage of: according to the concrete structure of workpiece, two fixture blocks with semi-circular groove are set to be clamped a plurality of workpiece simultaneously, and on locating piece, arrange dexterously can sectional fixture T-slot, alignment pin is installed from locating piece top to be clamped fixture, and then realize the accurate location to workpiece, simple in structure, flexible and convenient to use, clamping efficiency is high, and machining accuracy is high.

Accompanying drawing explanation

Fig. 1 is the structural representation of workpiece.

Fig. 2 is upper fixture block of the present utility model and the clamping schematic diagram of lower fixture block to workpiece.

Fig. 3 is the structural representation of pressing plate of the present utility model.

Fig. 4 is structural representation of the present utility model (not comprising pressing plate and upper and lower fixture block).

The specific embodiment

Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described.

As shown in Figures 1 to 4, the utility model comprises base 7, rectangle locating piece 10 is set on base 7, the top of locating piece 10 is threaded hole 9 and several alignment pin 11, the sidewall of locating piece 10 is with T-slot 8, the madial wall of T-slot 8 is with through hole 13, through hole 13 needs the bolt of Drilling operation 1 for installing, through hole 13 arranges a plurality of simultaneously, construction bolt 1 in batches, fixture block 2 and lower fixture block 3 are housed in T-slot 8, upper fixture block 2 and lower fixture block 3 sidewalls are all with semi-circular groove, described two half slots form a circular hole, described circular hole just in time can bolt 1 external diameter match, alignment pin 11 one end are stretched in T-slot 8, can exert pressure to upper fixture block 2, the other end withstands pressing plate 4, pressing plate 4 edges are with step 5, the edge mate of step 5 and locating piece 10, pressing plate 4 is connected by housing screw 6 and locating piece 10, housing screw 6 is arranged in screwed hole 9, can make pressing plate 4 several alignment pins 11 be compressed simultaneously, apply force rate compared with balance, clamping degree to each bolt 1 is more consistent, the sidewall of locating piece 10 is positioned at installs several screws 12, the end of screw 12 props up alignment pin 11, while not installing fixture block 2 and lower fixture block 3 in T-slot 8, can play the effect pre-fixing to alignment pin 11,

Using method of the present utility model is as follows:

The first step, is fixed on base 7 on operating desk;

Second step, makes to pack into fixture block 2 and lower fixture block 3 in T-slot 8;

The 3rd step, packs bolt 1 in the described circular hole forming and through hole 13 at upper fixture block 2 and lower fixture block 3;

The 4th step, screws housing screw 6, and pressing plate 4 is exerted pressure to several alignment pins 11 simultaneously, and then compresses upper fixture block 2 downwards;

The 5th step, carries out respectively Drilling operation to the bolt 1 of while clamping.

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.
