Abstract

The utility model relates to a combined vice which is a mechanical processing universal fixture which is combined by whole set elements. The combined vice has the functions that the combined fixture clamps and positions various parts, and has also the rigidity and the clamping efficiency of a plain vice. If only a positioning element is replaced, parts with different types can be clamped, and the positioning requirements of different angles and positions can be met. The clamping scope is enlarged by a combined structure. The processing efficiency and the processing precision are enhanced, and the labor intensity is reduced. The element is conveniently maintained and replaced, and the precision of the vulnerable part is easily repaired. The repeating use rate of the element is high, so that the cost of producing and running is lowered.

Description

Combined vice

The utility model belongs to the machining universal fixturing.

Existing parallel jaw has clamping efficient height, good rigidly, but to the clamping bad adaptability of special-shaped part.Though and existing built-up jig has highly versatile, almost can adapt to the clamping requirement of any irregular part, but complete number of elements is big, generally (is disregarding securing member interior) more than 3,000, and management needs the special messenger with assembling, its management workload is big, complete cost is higher tens times than vice, even hundred times, and its combination poor rigidity, blank is forged in the casting of incompatibility clamping again, directly influences stock-removing efficiency.

The purpose of this utility model is to improve the weak point of existing plain vice and a kind of like this vice is provided, can be during this vice clamping part to be processed by adjusting the distance and the length setting element of two jaws, select suitable setting element and special-shaped jaw for use, keep its combination rigidity, and can adapt to the location needs of different angles and position, reach the purpose that enlarges the clamping scope and improve working (machining) efficiency.Clamping mode is simple, rigidity is strong, almost can adapt to any irregular part and casting and forge the blank part in its clamping size range, machine tooling uses it can once determine the coordinate space of part to be processed, simplifies technology, raise the efficiency, and cost is the 5%-1% of complete built-up jig.

The utility model has following accompanying drawing:

Fig. 2 length setting element

Fig. 3 gengon cushion block

Fig. 4 elastic fulcrum bar

Fig. 5 angle orientation element

Retouch technical solutions of the utility model with accompanying drawing below.

In the accompanying drawings, marking each numeral is expressed as follows respectively:

1, guide rail base, 2, slide block, 3, movable clamp port, 4, fixed nip, 5, screw mandrel is paid, and 6, fixed block, 7, the angle orientation element, 8, length setting element, 9, protruding jaw, 10, calibration block, 11, location-plate, 12, angle bar, 13, the rotation location-plate, 14, stop screw, 15, the polyhedron cushion block, 16, butterfly spring, 17, overcoat, 18, joint, 19, pole.

The purpose of this utility model reaches by following measure: the basic structure of utilizing plain vice, but on the top guide pass of guide rail base (1), have many positioning splines, the method that tightens up with key location and screw is equipped with fixed block (6) at the one end, at its other end screw mandrel is housed and pays (5) and slide block (2), fixed block (6) and slide block (2) can both be that benchmark vertically moves with guide rail base (1) like this, when the screw mandrel adjustment amount is not enough, fixed block (6) can be vertically moved the back positioning and fastening on guide rail base (1), or cancellation guide rail base ((1), on platen, directly install and fix piece (6) and slide block (2), enlarged clamping range.Movable clamp port (3) and fixed nip (4) are installed in respectively on slide block (2) and the fixed block (6), are furnished with angle setting element (7) on its working face, (9) three kinds of annexes of length setting element (8) and protruding jaw.When needing the special-shaped workpiece of clamping, can so both guarantee the clamping rigidity of other part of various processed abnormal shapes, and can carry out space orientation to workpiece again by selecting suitable annex for use and adjusting correct distance between two jaws.

The purpose of this utility model can also reach by following measure: respectively there is a locating hole two sides at guide rail base (1), they all are equipped with the vertical coplane of rotating central hole of axle with the bottom surface, this structure makes the centre of gyration of guide rail base (1) be easy to centering, and has satisfied the axiality of tune processing work stomidium.The two bottom sides face of guide rail base (1) is equipped with the garden curved scale piece (10) of 45 degree graduation, like this can be at the revolute function that does not have to realize under the situation of turret base the combined type vice.Axle can play the role of fastening to guide rail base (1) by nuts and washers.For example: work as rotary table with the milling machine table face,, make the actual range of work of main frame obtain enlarging owing to there be not this big of the revolution pedestal of vice, and make vertical milling, for sleeping in mill all unaffected.

Fig. 1, Fig. 2, Fig. 3, Fig. 4 and Fig. 5 are a kind of embodiment, and as shown in Figure 5, angle orientation element (7) is polygonal panel or V-block, be drilled with many paired dowel holes in the above, and the two paired dowel hole lines of centres and its dual-side angle difference are 2 degree or 5 degree.According to the angle of workpiece, can select the angle orientation element (7) that matches with it like this.

About length setting element (8), be divided into two kinds by its structural behaviour:

1, as shown in Figure 2: by clamping the stepless adjustable-length setting element (8) that side location-plate (11), angle bar (12), rotation location-plate (13) and stop screw (14) are formed, each other by being threaded, adjust, fixing, finally make the residing position of stop screw, can adapt to the location needs of different angles and position.

2, polyhedron cushion block (15) as shown in Figure 3, each end face of its outer rim does not wait the distance of center positioning hole axis, the working face position is also just different, with alignment pin be installed in fixed block (6) but both single-piece use, also can many uses.

The protruding jaw of annex (9) is except having the rigid top rod type, but as long as the workpiece clamping point just should be furnished with the enough elastic fulcrum bars of rigidity more than 2 o'clock, elastic fulcrum bar butterfly spring (16) as shown in Figure 4, overcoat (17), joint (18) and pole (19) are formed, and this structure can guarantee push rod (19), and be stressed when being compressed 1-3mm, spring force changes in the 300-900 scope, has satisfied the tight requirement of various blank work piece positionings.

Be installed in as shown in Figure 1 and replace jaw effect, V-arrangement jaw to make the combined type vice not only accurately but also easily carry out the clamping location when two vee-blocks on fixed block (6) and the slide block (2) are used separately as to clamping garden dish workpiece garden dish work.

The utility model has following advantage than prior art, both had built-up jig to the clamping positioning function of various workpieces, the rigidity and the clamping efficient that have again plain vice, only need to change the just dissimilar workpiece of energy positioning and clamping of suitable setting element, and can adapt to the location needs of different angles and position, thus enlarged the clamping scope, improved working (machining) efficiency and machining accuracy, alleviate labour intensity, and greatly reduced production cost.
