Abstract

The invention belongs to the field of fixture equipment, and particularly relates to a drilling fixture for a drilling machine. The drilling fixture comprises a bottom plate, and is characterized in that a support block is arranged on the left of the bottom plate, a beam is arranged at an end of the support block, a through hole is arranged at an end of the beam, a drilling guide sleeve functioning in guiding is mounted in the through hole, a positioning stopper for limiting a workpiece is arranged in the middle of the bottom plate, an eccentric cam is arranged on the right of the bottom plate, and a handle convenient for people to rotate is arranged at the top of the eccentric cam. The drilling fixture can be used for rapidly positioning the workpiece, accelerating machining and reducing potential safety hazards in the machining process.

Description

Boring grab

Technical field

The invention belongs to anchor clamps servicing unit field, particularly a kind of simple in structure, the boring grab that can position workpiece fast.

Background technology

Machining is our main mode of production; Common car arranged, mill, plane, mill etc.; Cutter is as the indispensable parts of above-mentioned processing mode; The quality of cutter with and the quality of installing to being processed with significant effects, and the utilization of anchor clamps also helps improving the quality of various machinings.

In the boring process, people usually adopt hand-held mode to process for some simple parts; There are many problems in such mode: 1, artificial hand-held, in process, receive the influence of mechanical force, and hand exists easily rocks; Machining accuracy can not get guaranteeing; 2, adopt hand existences to need potential safety hazard, be unfavorable for staff's safety, 3, adopt the operating efficiency of aforesaid way to can not get assurance.

Summary of the invention

The present invention is directed to the deficiency of existing product, the present invention has designed a kind of can positioning workpiece fast, improves process velocity, reduces the boring grab of the potential safety hazard in the process.

The present invention realizes through following technical scheme:

Boring grab, it comprises base plate, it is characterized in that: the left side of described base plate is provided with back-up block; The end of back-up block is provided with crossbeam; The end of described crossbeam is provided with through hole, and the boring guide pin bushing that play the guiding role is installed in the through hole, and the middle part of described base plate is provided with carries out spacing position block to workpiece; The right side of described base plate is provided with eccentric cam, and the top of eccentric cam is provided with is convenient to the handle that people rotate.

In sum; Contact force with object is different when rotated through eccentric cam in the present invention; Realize clamping, adopt boring grab of the present invention, improved the clamping workpiece locating accuracy workpiece; Improve the speed of clamping, also can overcome the potential safety hazard that artificial offhand exists simultaneously.

Description of drawings

Fig. 1 is a structural representation of the present invention;

1 is base plate among the figure, and 2 is position block, and 3 is back-up block, and 4 is crossbeam, and 5 is handle, and 6 is eccentric cam.

The specific embodiment

Below in conjunction with accompanying drawing the present invention is further specified:

Boring grab as shown in Figure 1, it comprises base plate 1, the left side of described base plate 1 is provided with back-up block 3; The end of back-up block 3 is provided with crossbeam 4, and the end of described crossbeam 4 is provided with through hole, and the boring guide pin bushing that play the guiding role is installed in the through hole; The boring guide pin bushing carries out a guiding to drill bit, plays the effect of protection drill bit, prevents drill bit stressed excessive fractureing in working angles; The middle part of described base plate 1 is provided with carries out spacing position block 2 to workpiece, fast workpiece is positioned, and improves drilling accuracy; The right side of described base plate 1 is provided with eccentric cam 6; The top of eccentric cam 6 is provided with is convenient to the handle 5 that people rotate, and eccentric cam 6 is used for workpiece is fixedly clamped, the operation that people clamp and unclamp through 5 pairs of workpiece of rotary handle.

In sum; Contact force with object is different when rotated through eccentric cam in the present invention; Realize clamping, adopt boring grab of the present invention, improved the clamping workpiece locating accuracy workpiece; Improve the speed of clamping, also can overcome the potential safety hazard that artificial offhand exists simultaneously.
