Technical field

The invention belongs to jig field, more particularly, relate to the composite fixture that a kind of pressure can be surveyed.

Background technology

In machine industry, lathe is widely used in processing all kinds of parts, workpiece is reliably located adding man-hour requirement.Concerning the larger workpiece processing of single-piece, small lot, workload, generally can directly on platen, by adjusting fixture, realize positioning and clamping, the position of part is determined in the setting that by machining coordinate is then; For the part that has certain batch, need by selecting relevant special fixture to reduce labour intensity, reduce part processing non-cutting time, enhancing productivity.But when processing work, because processing content is different, conventionally to change special fixture, thereby reduce operating efficiency.For enterprise, in order to reduce cost, the versatility of fixture also should be taken into account, needs to guarantee that workpiece clamp pressure when clamping easily controls simultaneously.

Summary of the invention

The problem such as the clamping pressure that causes for existing fixture is wayward, special fixture versatility is not high, the invention provides a kind of pressure measurable type composite fixture.

For addressing the above problem, the present invention adopts following technical scheme.

A kind of pressure measurable type composite fixture, comprise clamping fixture seat, slide rail, large adjusting screw(rod), movable block, large clamp, minor adjustment screw rod, fixed block, little clamp, sensors A, sensor B, the lower end of described slide rail is arranged on clamping fixture seat, and the upper end of slide rail is stuck on the recessed edge in movable block lower end; Described large adjusting screw(rod) is meshed with movable block; Described large clamp lower end is pressed on the recessed edge in upper end of movable block, and the upper end of large clamp is provided with groove, and the vertical direction cross section on groove top is rectangle, and groove bottom is dovetail groove; Described fixed block is fixed on the groove side of large clamp; The upper end of described little clamp flushes with the groove upper end of large clamp, and the lower end of little clamp embeds in the dovetail groove of large clamp groove lower end; Described minor adjustment screw rod is meshed with fixed block, and one end of minor adjustment screw rod and little clamp are connected; On described large clamp, be provided with sensors A; On described little clamp, be provided with sensor B.

Than prior art, beneficial effect of the present invention is:

(1) the present invention is provided with large clamp and little clamp, to be applicable to the clamping of different size workpiece, has increased the versatility of special fixture.

(2) the present invention is provided with sensor on large clamp and little clamp, can be when clamp move, and assurance clamp in OK range, is unlikely to damage workpiece to the pressure of workpiece; Pressure during simultaneously Workpiece clamping for unlike material and size is made statistical table, convenient while operating in the future as a comparison, thereby increase work efficiency.

(3) the present invention is simple in structure, reasonable in design, is easy to manufacture.

Accompanying drawing explanation

Fig. 1 is front view of the present invention;

Fig. 2 is that Fig. 1 is along the cutaway view of A-A line;

Fig. 3 is top view of the present invention.

In figure: 1-slide rail, 2-large adjusting screw(rod), 3-movable block, 4-large clamp, 5-minor adjustment screw rod, 6-fixed block, 7-little clamp, 8-sensors A, 9-sensor B.

The specific embodiment

Below in conjunction with accompanying drawing, describe the present invention.

As shown in Figure 1, Figure 2, Figure 3 shows, pressure measurable type composite fixture comprises clamping fixture seat, slide rail 1, large adjusting screw(rod) 2, movable block 3, large clamp 4, minor adjustment screw rod 5, fixed block 6, little clamp 7, sensors A 8, sensor B9, the lower end of described slide rail 1 is arranged on clamping fixture seat, and the upper end of slide rail 1 is stuck on the movable block 3 recessed edge in lower end, described large adjusting screw(rod) 2 is meshed with movable block 3, described large clamp 4 lower ends are pressed on the recessed edge in upper end of movable block 3, the upper end of large clamp 4 is provided with groove, the vertical direction cross section on groove top is rectangle, groove bottom is dovetail groove, described fixed block 6 is fixed on the groove side of large clamp 4, the upper end of described little clamp 7 flushes with the groove upper end of large clamp 4, the lower end of little clamp 7 embeds in the dovetail groove of large clamp 4 groove lower ends, described minor adjustment screw rod 5 is meshed with fixed block 6, one end of minor adjustment screw rod 5 and little clamp 7 are connected, on described large clamp 4, be provided with sensors A 8, on tight 7 of described clip, be provided with sensor B9.

When the certain workpiece of processing dimension, rotation minor adjustment screw rod 5, makes little clamp 7 away from fixture center; Rotate large adjusting screw(rod) 2, movable block 3 is under the effect of large adjusting screw(rod) 2, slide rail 1 is slided to centre on clamping fixture seat, thereby drive the clamping of moving and complete of large clamp 4 to move, pressure when now sensors A 8 inductions clamp, and pass to display screen, guarantee the chucking power of workpiece to be unlikely to excessive.Otherwise the large adjusting screw(rod) 2 of counter-rotating can loosen workpiece.
