Description
Technical field
The utility model relates to process equipment field, and specifically a kind of bracket frame modular fixture, is mainly used in needing multi-angle, the processing of multilevel bracket frame circumference.
Background technology
Fixture refers in machine-building process and is used for fixing processing object, makes it to occupy correct position, with the device of accepting construction or detecting.Fixture claims again jig, and in a broad sense, any operation in technical process, is used for installing rapidly, easily and safely the device of workpiece, all can be described as fixture.Such as weld jig, inspection jig, assembling jig, jig etc.Wherein jig is the most common, often referred to as fixture.On lathe, during processing work, for making the surface of workpiece can reach size, geometry and the specification requirements such as relative-position error surperficial with other of drawing regulation, before processing, workpiece must be installed to (location), clip (clamping).Fixture is conventionally by compositions such as setting element (determining the tram of workpiece in fixture), clamping device, tool setting induction element (determining relative position or the guiding tool orientation of cutter and workpiece), indexing means (make workpiece can complete the processing of several stations in once mounting, have circular index device and traveling priority indexing means two classes), Connection Element and clamp bodies (clamp base)
Fixture kind can be divided into by handling characteristics: 1. universal fixture.As machine vice, chuck, sucker, dividing head and rotary table etc., have very large versatility, can adapt to preferably the conversion of manufacturing procedure and processing object, its structure is shaped, the seriation of size, specification, wherein great majority have become a kind of standard accessory of lathe.2. specificity fixture.For the clamping of certain product parts on certain procedure needs specialized designs manufacture, service object is single-minded, and specific aim is very strong, generally by product manufactory designed, designed.Conventional have turning attachment, fraise jig, drill jig (guiding cutter hole or the jig of the use that reams on workpiece), boring template (guiding the boring cutter bar jig that bore hole is used on workpiece) and a pallet (for the mobile clamping on transfer line of modular machine, automatic production line of modular machine).3. flexible jig.Can change or adjust the special fixture of element.4. built-up jig.The fixture being comprised of the standardized component of difformity, specification and purposes, is applicable to single-piece, small serial production and temporary duty that trial production of new products and product are often changed.
Although fixture is of a great variety at present, but for some special-shaped workpiece, particularly need the special-purpose special-shaped workpiece of repeatedly counting, multi-angle is processed, also there is no a kind of reliable special fixture, such as bracket frame, generally for fixation, mostly need to design many support bars asymmetrically, but for convenient fixing, and fool-proof design, it is asymmetric that many support bars tend to be designed to, and just need to have a mark in process, also do not have at present a kind ofly for the processing of bracket frame circumference, can carry out concise and to the point mark bracket frame circumference modular fixture specially.
Summary of the invention
The utility model is for above technical problem, provides a kind of and for the processing of bracket frame circumference, can carry out concise and to the point mark bracket frame circumference modular fixture specially.
The utility model is achieved through the following technical solutions.
A kind of bracket frame modular fixture, comprise chuck body, positioning spindle, positioning fastener, mark screw rod, standing screw, it is characterized in that arranging in chuck body a plurality of through holes, positioning spindle is connected with positioning fastener after passing through hole middle in chuck body, to realize fixing workpiece, mark screw rod is through one of them through hole in chuck body, workpiece direction is carried out to mark, the screw portion of mark screw rod is divided into two sections of sizes, standing screw is a plurality of, a plurality of standing screws through the through hole in chuck body, carry out auxiliary positioning to workpiece respectively.Chuck body is L-shaped, and the through hole in chuck body is arranged on vertical plane.Via count in chuck body is five, each of corner location, middle one.Larger screw portion on mark screw rod and the threaded shank of standing screw are graded greatly.
The utility model utilizes mark screw rod to carry out mark to workpiece direction, and onesize by larger section of standing screw and mark screw rod is arranged to, therefore, can the adjustment along with workpiece by mark screw rod, by through holes different in chuck body, be fixed.Like this, at workpiece, carry out multi-step and add man-hour, mark screw rod can be carried out to mark by through holes different in chuck body, can realize step by step the repeatedly stable processing of number, multi-angle of special-shaped workpiece.
Accompanying drawing explanation
In accompanying drawing, Fig. 1 is the utility model structural representation, wherein:
1-chuck body, 2-positioning spindle, 3-positioning fastener, 4-mark screw rod, 5-standing screw.
Specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
A kind of bracket frame modular fixture, comprise chuck body 1, positioning spindle 2, positioning fastener 3, mark screw rod 4, standing screw 5, it is characterized in that arranging in chuck body 1 a plurality of through holes, after passing through hole middle in chuck body 1, positioning spindle 2 is connected with positioning fastener 3, to realize fixing workpiece, mark screw rod 4 is through one of them through hole in chuck body 1, workpiece direction is carried out to mark, the screw portion of mark screw rod 4 is divided into two sections of sizes, standing screw 5 is a plurality of, a plurality of standing screws 5 are respectively through the through hole in chuck body 1, workpiece is carried out to auxiliary positioning.Chuck body 1 is L-shaped, and the through hole in chuck body 1 is arranged on vertical plane.Via count in chuck body 1 is five, each of corner location, middle one.Larger screw portion on mark screw rod 4 and the threaded shank of standing screw 5 are graded greatly.
The utility model utilizes 4 pairs of workpiece directions of mark screw rod to carry out mark, and by larger section of standing screw 5 and mark screw rod 4 is arranged to onesize, therefore, can the adjustment along with workpiece by mark screw rod 4, by through holes different in chuck body 1, be fixed.Like this, at workpiece, carry out multi-step and add man-hour, mark screw rod 4 can be carried out to mark by through holes different in chuck body 1, can realize step by step the repeatedly stable processing of number, multi-angle of special-shaped workpiece.
