Description

Workpiece assembles fixture

Technical field

This utility model relates to clamp art.

Background technology

The most general fixture mainly has the fixtures such as vice, flat-nose pliers, V shape iron.Due to vice and flat-nose pliers Jaw plate is all flat board, can only be clamped by the two sides being parallel to each other that the cross section of clamping workpiece is rule regular polygon Workpiece；V shape iron supports cylindrical work only with its V-shaped part part, then coordinates vice or flat-nose pliers by Workpiece clamping.

During for the assembling of parts, need fast-assembling cache, and the form of diverse of part, and for there is inclined plane Gradient workpiece, these workpiece cannot utilize the fixtures such as above-mentioned conventional vice, flat-nose pliers, V shape iron firmly to clamp.So, design one Plant the fixture being specifically designed for wedge shape Workpiece clamping, be current technical staff's problem demanding prompt solution.

Utility model content

This utility model is intended to provide a kind of workpiece to assemble fixture, it is possible to be clamped the workpiece with inclined plane, side Just the assembling of workpiece.

Workpiece in this programme assembles fixture, including pedestal, and two calipers being connected on pedestal, also include all becoming To the grip block, spring and the slide bar that arrange, two described calipers all have horizontal through hole, are enclosed within slide bar in this through hole, Slide bar be respectively arranged at two ends with more than the inner limited block of through hole and outer limited block, described spring overcoat on slide bar, the two of spring End offsets with inner limited block, caliper respectively；Described inner limited block is provided with the groove that cross section is major arc shape, two described clampings Plate is all provided with the major arc shape fin of correspondence, and this major arc shape fin coordinates in major arc connected in star.

Beneficial effect: when not laying workpiece, slide bar is to medial movement under the promotion of spring, and grip block is at the bullet of spring It is extruded under power effect, drawing close to centre of grip block.During use, grip block is opened laterally, workpiece is placed on two clampings Between plate, grip block is close to against workpiece, grip block and workpiece slope under spring force effect thus is realized clamping, it is simple to people Work is installed；Simultaneously because be clamped by spring, so manually quickly grip block can manually be opened, so energy Enough realizations quickly clamp operation.

Using such scheme, grip block connects the fin of end and can rotate at groove, thus ensures that grip block can It is freely rotatable, to adapt to the wedge shape workpiece of differing tilt angles, there is the feature of fast-assembling cache simultaneously, substantially increase assembling Efficiency.

Further, arbitrary described caliper is slidably connected on pedestal, this slidably caliper be provided with tapped through hole, screw thread Being combined with lock-screw in hole, end and the pedestal of described lock-screw offset.Unscrew lock-screw, can arbitrarily slide movable Caliper, to regulate the distance between two calipers, thus adapt to various sizes of workpiece.

Further, described pedestal is provided with the chute slided for caliper, and the cross section of this chute is convex shape, caliper Both sides, bottom are provided with the projection corresponding with chute shape.Chute cross section is set to convex shape, it is possible to the projection on caliper Playing the restriction on longitudinally, limit caliper and move up and down, the slip of caliper is more stable.

Further, the top and bottom of described inner limited block are all provided with chamfering, compare right angle, and grip block is provided with bigger Revolution space.

Further, the lateral surface of described grip block is provided with arcuate groove, adds the revolution space of grip block.

Accompanying drawing explanation

Fig. 1 is the structural representation that this utility model workpiece assembles fixture embodiment；

Fig. 2 is the structural representation in Fig. 1 at A-A.

Detailed description of the invention

Below by detailed description of the invention, this utility model is described in further detail:

Reference in Figure of description includes: pedestal 1, caliper 2, lock-screw 21, slide bar 3, outer limited block 31, interior Limited block 32, spring 4, grip block 5, workpiece 6.

Embodiment is the most as shown in Figures 1 and 2:

Workpiece in this programme assembles fixture, including pedestal 1, and two calipers 2 being connected on pedestal 1, left Caliper 2 is welded on pedestal 1, and the caliper 2 of right is slidably connected on pedestal 1.Tapped through hole, spiral shell is had on the caliper 2 of right Being combined with lock-screw 21 in pit, the end of lock-screw 21 contacts with pedestal 1 and pushes against.Unscrew lock-screw 21, can be random The caliper 2 of slip right, to regulate the distance between two calipers 2, thus adapts to various sizes of workpiece 6.

All having horizontal through hole on each caliper 2, be enclosed within this through hole in slide bar 3, the two ends of slide bar 3 are respectively welded More than inner limited block 32 and the outer limited block 31 of through hole, being enclosed within slide bar 3 outside spring 4, the two ends of spring 4 are respectively and inner limited block 32, caliper 2 offsets；Described inner limited block 32 is provided with the groove that cross section is major arc shape, and it is right that two described grip blocks 5 are all provided with The major arc shape fin answered, this major arc shape fin coordinates in major arc connected in star.

Caliper 2 and the concrete mode that is slidably connected of pedestal 1 on the right be: is machined with chute on pedestal 1, this chute transversal Face is convex shape, and the both sides, bottom of caliper 2 are provided with the projection corresponding with chute shape.Chute cross section is set to convex shape, Projection on caliper 2 can play the restriction on longitudinally, limit caliper 2 and move up and down, the slip of caliper 2 is more stable.

The top and bottom of inner limited block 32 are all provided with chamfering, and the lateral surface of grip block 5 is provided with arcuate groove, adds folder Hold the revolution space of plate 5.

Operation principle: when not laying workpiece 6, slide bar 3 is to medial movement under the promotion of spring 4, and grip block 5 is at spring It is extruded under the elastic force effect of 4, drawing close to centre of grip block 5.During use, grip block 5 is opened laterally, workpiece 6 is placed Between two grip blocks 5, grip block 5 be close to against workpiece 6, grip block 5 and workpiece 6 inclined-plane under spring 4 elastic force effect thus Realize clamping, it is simple to manually install；Simultaneously because be clamped by spring 4, so can manually the most manually Open grip block 5, so being capable of quickly clamping operation.

Above-described is only embodiment of the present utility model, and in scheme, the known general knowledge such as concrete structure and characteristic is at this Too much describe.It should be pointed out that, for a person skilled in the art, in the premise without departing from this utility model structure Under, it is also possible to making some deformation and improvement, these also should be considered as protection domain of the present utility model, and these are all without impact The effect of this utility model enforcement and practical applicability.The protection domain that this application claims should be with the content of its claim Being as the criterion, the detailed description of the invention in description etc. records the content that may be used for explaining claim.
