Abstract

The utility model discloses a clamp having a floating-type positioning pin. The clamp comprises a substrate, multiple supporting columns located at one side of the substrate and used for supporting the substrate, an air cylinders located at the same side of the substrate with respect to the supporting columns, a fixing plate located at one end of the air cylinder and used for fixing the air cylinder, a locking block located at the other side of the air cylinder, and a floating-type positioning pin driven by the air cylinder and capable of penetrating through the substrate. According to the utility model, a locating or locating assisting function is realized, thereby ensuring that products to be processed can be more stable during the processing process, enabling the size control to be more flexible, and effectively guaranteeing the precision of the products.

Description

The fixture with floating location pin
Technical field
The utility model relates to a kind of fixture with floating location pin.
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 power mouth work workpiece 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 substrate homonymy a cylinder, be positioned at cylinder one end and fixedly cylinder fixed head, be positioned at the latch segment of cylinder opposite side, by air cylinder driven and can pass the floating location pin of substrate.
Preferably, described floating location pin comprises head and for the reciprocating spring of supporting head part.
Preferably, the number of described cylinder is two, and floating location pin is also two.
Preferably, the height of described floating location pin is greater than the height of latch segment.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
The utility model is realized the function of location or auxiliary positioning, can guarantee that like this processed product has higher stability in process, size Control is got up more flexibly individual, has effectively guaranteed the precision of product.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further described:
Fig. 1 is schematic perspective view of the present utility model.
Fig. 2 is the combination schematic perspective view of floating location pin and cylinder in the utility model.
Fig. 3 is the schematic perspective view under another visual angle of the utility model.
The specific embodiment
Embodiment: shown in figure 1-3, the utility model provides a kind of specific embodiment with the fixture of floating location pin, and it comprises: substrate 10, be positioned at substrate 10 1 sides and for several support columns 12 of supporting substrate 10, with support column 12 be positioned at substrate 10 homonymies a cylinder 20, be positioned at cylinder 20 one end and fixedly cylinder 20 fixed head 22, be positioned at cylinder 20 other ends latch segment 24, by cylinder 20, drive and can pass the floating location pin 30 of substrate 10.
Floating location pin 30 comprises head 32 and for the reciprocating spring 34 of supporting head part 32.
The utility model is according to the distortion of processed product and self flexible modulation, after adjusting completes, cylinder 20 starts and withstands latch segment, make floating location pin 30 complete and contact with processed product, realize the function of location or auxiliary positioning, can guarantee that like this processed product has higher stability in process, size Control be got up more flexibly individual, effectively guarantee the precision of product.
Certainly above-described embodiment is only explanation technical conceive of the present utility model and feature, and its object is to allow person skilled in the art can understand content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalent transformations of doing according to the Spirit Essence of the utility model main technical schemes or modification, within all should being encompassed in protection domain of the present utility model.
