Description

The multiple positioner of a kind of workpiece

Technical field

The utility model relates to a kind of object positioner, is specifically related to a kind of multiple positioner that is used for workpiece.

Background technology

As everyone knows, in the manufacture process of product, part processing is generally all accomplished through various device, on equipment during processing parts, usually by means of clamping apparatus to part to be processed along positioning and fix on the three-dimensional of solid.Traditional mechanical being clipped on the direction mostly only has one-time positioning mechanism at present, and the precision of one-time positioning is often lower, and this just has its limitation for miniature or precision component, and the one-time positioning that precision is lower will cause the reduction of part processing precision.

The utility model content

The utility model technical problem to be solved is; Overcome the existing lower deficiency of Working piece positioning device precision; Provide a kind of workpiece multiple positioner; It has the second positioning function on same direction, thereby reaches positioning accuracy height, effect that adjusting range is big, is particularly useful for small precision component.

The technical scheme that the utility model solves its technical problem is:

The multiple positioner of a kind of workpiece; It comprises block, big V-block, sliding shoe, Cam Follower, little V-block, movable block, spring and spring fixed block; The end side surface that said big V-block is longitudinally gone up is close proximity to block; Other end side is provided with V-shaped groove, and said Cam Follower is fixedly linked in the end of said sliding shoe and longitudinally pushes against in the V-shaped groove of said big V-block, and said spring fixed block, movable block and little V-block longitudinally are fixed in the last plane of said big V-block with being arranged in order; This little V-block is provided with the V-shaped groove of place work piece in the face of the side of movable block; This movable block is articulated on the said big V-block and can swings, and said spring clip places between said spring fixed block and the movable block, and pushes an end of movable block the V-shaped groove of said little V-block to.

The multiple positioner of the described workpiece of the utility model is provided with blind hole on its spring fixed block and the movable block separately, and the two ends of said spring are placed in respectively in this blind hole; Said little V-block and spring fixed block are fixed on the said big V-block through screw, and the middle part of said movable block is articulated on the said big V-block through removable pin; Said sliding shoe connects through bolt with Cam Follower.

The utility model carries out the location first time through movable block to workpiece on little V-block, through big V-block and Cam Follower workpiece is done location for the second time again, therefore has the function of multiple location.When if the workpiece of placing does not accurately put in place for the first time; Can carry out the location second time through the utility model; Thereby the utility model can carry out multiple location to workpiece in a big way; Have advantage simple in structure, easy to operate, that positioning accuracy is high, be specially adapted to the circular location that approaches optical filter and some tiny cylindrical works on mobile lens and the camera lens.

Description of drawings

Fig. 1 is the structure chart of the utility model.

Fig. 2 is the side view of Fig. 1.

Wherein, 1 sliding shoe, 2 Cam Followers, 3 little V-blocks, 4 fixing threaded holes, 5 blocks, 6 screws, 7 spring fixed blocks, 8 springs, 9 fixing holes, 10 movable blocks, 11 workpiece, 12 big V-blocks.

The specific embodiment

Combine specific embodiment and accompanying drawing that the utility model is described further at present.

Please combine to consult the sketch map of Fig. 1 and Fig. 2 the utility model, the multiple positioner of diagram workpiece comprises block 5, big V-block 12, sliding shoe 1, Cam Follower 2, little V-block 3, movable block 10, spring 8 and spring fixed block 7.

Said block 5 is fixed on the process equipment.The end side surface that said big V-block 12 is longitudinally gone up is close proximity to block 5, and its another end side surface is provided with a V-shaped groove.Said Cam Follower 2 is connected in the end of said sliding shoe 1 through bolt, and this sliding shoe 1 longitudinally (direction of arrow B) moves and drives Cam Follower 2 and pushes against in the V-shaped groove of said big V-block 12.Said spring fixed block 7, movable block 10 and little V-block 3 longitudinally are fixed in the last plane of said big V-block 12 with being arranged in order.Said little V-block 3 is provided with fixing threaded hole 4, and it is fixed on the said big V-block 12 through screw, and this little V-block 3 is provided with the V-shaped groove of place work piece 11 in the face of the side of movable block 10.The middle part of said movable block 10 is provided with fixing hole 9, and it is articulated on the said big V-block 12 through removable pin and can swings.Said spring fixed block 7 is fixed on the said big V-block 12 through two screws 6, and the side of this spring fixed block 7 is provided with a blind hole, also is provided with a blind hole on the side of said movable block 10 1 ends.Said spring 8 is folded between said spring fixed block 7 and the movable block 10; And its two ends are placed in respectively in the blind hole of this spring fixed block 7 and movable block 10; The elastic force that said spring 8 relies on self is pushed an end of movable block 10 V-shaped groove of said little V-block 3 to, thereby with workpiece 11 location and clamping.

The course of work of the multiple positioner of the described workpiece of the utility model is following:

As shown in Figure 1; To the outer end application of force of movable block 10, an end pressuring spring 8 of movable block 10 also outwards moves away the V-shaped groove of little V-block 3 in the direction of arrow A, this moment workpiece 11 is put into the V-shaped groove of little V-block 3; Regain the ejecting force of movable block 10 outer ends then; The elastic force of spring 8 is pushed an end of movable block 10 V-shaped groove of said little V-block 3 to, and movable block 10 pushes against workpiece 11 to the V-type limit of V-shaped groove, thereby workpiece 11 is carried out one-time positioning and clamping.If also do not reach the requirement of location, sliding shoe 1 will move in the direction of arrow B, drive on the V-type limit of V-shaped groove that Cam Follower 2 is pressed in big V-block 12, thereby carry out second location again, make workpiece 11 reach hi-Fix.

The utility model is not limited in above-mentioned embodiment, and in the scope of the utility model, any non-substantial variations, remodeling, interpolation or the replacement made all should belong to the protection domain of the utility model.
