Abstract
The utility model discloses a clamp, comprising a substrate, multiple supporting columns located at one side of the substrate and used for supporting the substrate, multiple air cylinders at the same side of the substrate with respect to the supporting columns, and multiple clamping members arranged at the other side of the substrate, wherein the clamping members are controlled pneumatically by a number of the air cylinders. Compared with a manual locking screw clamping device, the clamp of the utility model is advantaged in that the production efficiency is relatively substantially improved; the uncertain factors during the processing process are reduced; the quality stability is guaranteed; and the employees' labor intensity is lowered.
Description
Technical field
The utility model relates to a kind of fixture.
Background technology
High speed development along with computer technology, there is the change of essence in traditional manufacturing industry, utilize Digit Control Machine Tool processing, the quality conformance of its product processing is good, the efficiency of machining accuracy all exceeds much than machine tool, especially at irregular, the complicated curve of profile or by the product of the processing of face, Alternative Composite and high-precision requirement, add man-hour, its advantage is that traditional machine tool is incomparable.Fixture is the important component part of numerical control machining center, its effect is that workpiece is fixed on the accurate location of lathe, complete the various processing to workpiece, the reliable clamping again that should walk accurately, obviously the quality of its structure has vital impact to machining accuracy, working (machining) efficiency; The special fixture that digital control processing is used seldom, is all generally that workpiece is placed on parallel jaw, with dial gauge centering position, more auxiliary with a little parallels, angle bar location, then with parallel jaw, clamp.Add and also will measure and arrange workpiece coordinate system man-hour, inefficiency, and positioning precision is not high.And clamped one time can only processing work Yi Ge orientation machined surface.For the small or in irregular shape element of size, utilize general hanger or fixture fixing more difficult, and take time and effort.Some parts need to carry out fine finishining to its positive and negative, and like this, two faces all need there is higher positioning precision when location.In prior art, do not have a kind of fixture to provide not only accurately but also positioning clamping fast this part, when processing another side, often need to change fixture, affect efficiency.
Summary of the invention
In view of the defect that above-mentioned prior art exists, the utility model object is to propose a kind of fixture in order to overcome above-mentioned shortcoming.
The technical solution of the utility model is: a kind of fixture, it comprises: substrate, be positioned at substrate one side and for several support columns of supporting substrate, with support column, be positioned at several cylinders of substrate homonymy and be arranged on several holders of substrate opposite side, wherein said holder is by the wherein cylinder pneumatic control of a part.
Preferably, it further comprises several limited blocks, several back-up blocks and several floating location pins, and wherein said limited block and back-up block are positioned at substrate opposite side, and floating location pin is by the cylinder pneumatic control of another part.
Preferably, described holder comprises by the connecting rod of air cylinder driven, is connected with connecting rod and around the depression bar of rotating shaft campaign, the pull bar coordinating with depression bar and brace.
Preferably, described cylinder comprises for the first cylinder of pneumatic actuation holder and the second cylinder of pneumatic actuation floating location pin.
Preferably, it further comprises fixes the fixed head of the second cylinder and the latch segment that allows floating location pin to pass, and wherein fixed head and latch segment are positioned at substrate one side.
Preferably, described limited block lays respectively at the surrounding of substrate, and is highly greater than the height of back-up block.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
The utility model is compared with traditional manual lock screw clamping tool, and production efficiency is greatly improved: reduce uncertain factor in process, guaranteed quality stable; Reduced employee's labour intensity.
