Description

Efficient bore hole workpiece positioning clamp

Technical field

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

Background technology

The precision workpiece of the high-accuracy requirement of processing at present uses machining center more, before being processed, workpiece needs first workpiece to be positioned, especially workpiece there are a plurality of holes, and each hole also will have the location of the workpiece of position relationship must be accurately, although otherwise the precision in the single hole that processes meets the requirements, the positional precision between Kong Yukong also larger error can occur.

The utility model content

The utility model provides a kind of efficient bore hole workpiece positioning clamp for above-mentioned shortcoming of the prior art, and it is simple in structure, and is flexible and convenient to use, and positioning accuracy is high.

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

Efficient bore hole workpiece positioning clamp comprises the chassis, is provided with block on the chassis, on the block sidewall with locating hole, on the chassis also with fixing hole and balancing weight; The block sidewall is fastened with sliding block, is provided with top shoe on sliding block, and the sliding block sidewall is equipped with hold-down screw and alignment pin; The sidewall of top shoe arranges adjustment screw with elongated hole in elongated hole; The second face on first surface on sliding block and top shoe cooperatively interacts and is the inclined-plane; Positioner is set on top shoe, and positioner comprises square locating piece, and locating piece at right angle setting positioning screw is in the locating hole on the first end insertion block of described positioning screw; One side of locating piece contacts with top shoe.

The utility model has the advantage of: slide block and the block that can mutually move is set on the chassis, the positioner of workpiece is coordinated with block, after processing preceding working procedure, only another sidewall of the locating piece on positioner need be coordinated with top shoe and can carry out next procedure, guarantee the Working position precision in each hole on workpiece; Simultaneously alignment pin is installed on sliding block, can be guaranteed the positional precision of slide block on the chassis, and then control the machining accuracy of workpiece, balancing weight is set on the chassis, make when rotating together with the rotating disk of chassis and equipment more steady.

The specific embodiment

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

As extremely shown in Figure 5 in Fig. 1, the utility model comprises chassis 4, be provided with block 42 on chassis 4, on block 42 sidewalls with locating hole 43, also with fixing hole 41 and balancing weight 5, chassis 4 can be fixed on the rotating disk of equipment by fixing hole 41 on chassis 4, balancing weight 5 can the chassis plays the effect of balance during 4 rotation, make chassis 4 smooth operations, do not affect the machining accuracy of workpiece; Block 42 sidewalls are fastened with sliding block 2, are provided with top shoe 1 on sliding block 2, and sliding block 2 sidewalls are equipped with hold-down screw 22 and alignment pin 23, and alignment pin 23 can take out, and can be used to monitor top shoe 1 and the positional precision of sliding block 2 on chassis 4; The sidewall of top shoe 1 is with elongated hole 12, the interior adjustment screw 13 that arranges of elongated hole 12, and when not screwing adjustment screw 13, top shoe 1 can move on sliding block 2; Second 11 on first surface 21 on sliding block 2 and top shoe 1 cooperatively interacts and is the inclined-plane, being conducive to moving; Positioner 3 is set on top shoe 1, and positioner 3 comprises square locating piece 31, and locating piece 31 at right angle setting positioning screws are in the locating hole 43 that the first end 32 of described positioning screw inserts on block 42; One side of locating piece 31 contacts with top shoe 1;

Using method of the present utility model is as follows:

Workpiece is matched with the second end 33 of described positioning screw, after processing a hole, top shoe 1 is moved horizontally, itself and locating piece 31 are separated, with the interior extraction of locating piece 43 from block 42 of the first end 32 of positioning screw, make in another side of locating piece 31 and match with top shoe 1, complete the processing of next procedure.
