Abstract

The utility model discloses a clamp which comprises a tetragonal clamp body (1), wherein a plurality of positioning holes (2) are formed on the clamp body (1), two positioning convex blocks (3) are arranged on the clamp body (1), and the positioning convex blocks (3) are arranged on two corresponding ends on the same side of the clamp body (1). The utility model provides the clamp which is simple to use and has good positioning effect for solving the shortcomings in the prior art.

Description

Anchor clamps
Technical field
The utility model relates to a kind of anchor clamps.
Background technology
High speed development along with computer technology, the change of essence has taken place in traditional manufacturing industry, utilize Digit Control Machine Tool processing, the quality conformance of its product processing is good, the efficient of machining accuracy all exceeds much than machine tool, especially add man-hour at the plant product of compoundization processing and high-precision requirement of irregular, the complicated curve of profile or curved surface, multiplex (MUX), its advantage is that traditional machine tool is incomparable.Anchor clamps are important component parts of numerical control machining center, its effect is that workpiece is fixed on the accurate position of lathe, finish various processing to workpiece, should accurate positioning reliable clamping again, obviously the quality of its structure has fundamental influence to machining accuracy, working (machining) efficiency; The special fixture that digital control processing is used generally all is that workpiece is placed on the parallel jaw seldom, and is auxiliary again with a little parallels, angle bar location with dial gauge centering position, clamps with parallel jaw then.Add and also will measure and be provided with workpiece coordinate system man-hour, inefficiency, and positioning accuracy is not high.And clamping can only an orientation of processing work machined surface.For the small or in irregular shape element of size, utilize the fixing relatively difficulty of general hanger or anchor clamps, and take time and effort.The part that has need carry out fine finishining to its positive and negative, and like this, two faces all need high orientation precision when the location.Do not have a kind of anchor clamps to provide not only accurately but also positioning clamping fast in the prior art, when the processing another side, often need to change anchor clamps, influence efficient this part.In machinery manufacturing industry, use the low key element of precision such as black skin very common as the situation of processing location benchmark, because blanks etc. are low as location reference dimension, positional precision, if selection of location datum is utilized improper, very easily cause causing workpiece machining element position deviation owing to the location goes wrong.As on the workpiece boss, carry out the hole, the groove class adds man-hour, lacks the defective that effective location is easy to occur hole on the workpiece, the designing requirement of groove class position deviation, has a strong impact on the product function of use.
Summary of the invention
In order to overcome the deficiency that prior art exists, the purpose of this utility model is to provide a kind of anchor clamps simple, good positioning effect that use.
For reaching above purpose, the utility model provides a kind of anchor clamps, comprise tetragonal chuck body, described chuck body is provided with a plurality of locating holes, described chuck body is provided with two locating convex blocks, and described locating convex block is arranged on the opposite ends of described chuck body the same side.
Further improvement of the utility model is that described chuck body center also is provided with and the equidirectional outwards outstanding load-bearing projection of described locating convex block.
Further improvement of the utility model is, described load-bearing projection be shaped as circle.
Further improvement of the utility model is that the diameter of described load-bearing projection is 4cm.
Further improvement of the utility model is that each described locating convex block is provided with locating hole.
The beneficial effects of the utility model are: owing to adopted above technical scheme, by a plurality of locating holes, two locating convex blocks are set on chuck body, and be arranged on the opposite ends of chuck body the same side, reach the purpose that allows anchor clamps precisely locate, also avoided simultaneously the phenomenon of the inclination or the skew of anchor clamps in process, improved the precision of converted products, the stable quality of assurance.
Description of drawings
Accompanying drawing 1 is the front view of anchor clamps in the present embodiment.
Wherein
1, chuck body; 2, locating hole; 3, locating convex block; 4, load-bearing projection.
The specific embodiment
Below preferred embodiment of the present utility model is described in detail, thereby protection domain of the present utility model is made more explicit defining so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that.
Referring to accompanying drawing 1, a kind of anchor clamps comprise tetragonal chuck body 1, and chuck body 1 is provided with a plurality of locating holes 2, and chuck body 1 is provided with two locating convex blocks 3, and locating convex block 3 is arranged on the opposite ends of chuck body 1 the same side.Use the position of the whole anchor clamps in locating convex block 3 fixing backs just to determine.Each locating convex block 3 is provided with locating hole 2, and after using locating convex block 3, for the secure effect, 2 pairs of anchor clamps of locating hole that screw passes on the locating convex block 3 carry out once more fixing.
Chuck body 1 center also is provided with and locating convex block 3 equidirectional outwards outstanding load-bearing projections 4.Load-bearing projection 4 be shaped as circle, can also be other shapes certainly, as triangle, rectangle etc.Circular load-bearing projection 4 can reduce in the process of processing and the interference of body, avoids owing to load-bearing projection 4 corner angle being arranged, and cutter is scratched by the corner angle of load-bearing projection 4.
The diameter of load-bearing projection 4 is 4cm, the meeting of too small load-bearing projection 4 makes the anchor clamps crank, easy because mobile drive load-bearing projection 4 centre-of gravity shifts of the mobile or external cutter of anchor clamps in process, cause the run-off the straight of anchor clamps own, finally cause the skew of Working position, the quality of influence processing.
By above embodiment as can be seen, the utility model is a kind of anchor clamps simple, good positioning effect that use.
Above embodiment only is explanation technical conceive of the present utility model and characteristics; its purpose is to allow the people that is familiar with this technology understand content of the present utility model and is implemented; can not limit protection domain of the present utility model with this, all equivalences of doing according to the utility model spirit essence change or modification all is encompassed in the protection domain of the present utility model.
