Abstract
The invention discloses a processing fixing clamp, which comprises a clamp body, a mandrel, a pressing piece and a nut. A holding groove for holding workpieces is disposed on the top of the clamp body, the bottom end of the mandrel is fixed into the holding groove and positioned in the center of the holding groove, the diameter of the mandrel is determined according to the diameters of inner holes of the to-be-processed workpieces, the two workpieces are sleeved on the mandrel, to-be-processed surfaces of the two workpieces are attached to each other, the pressing piece is positioned at the top end of the mandrel, and the nut is arranged on the upper side of the pressing piece, is sleeved at the top end of the mandrel and presses the pressing piece, so that the two workpieces are fixed onto the clamp body. The processing fixing clamp is used for processing the workpieces, the two workpieces can be simultaneously clamped at one step, processing consistency of the workpieces is guaranteed, the efficiency of the workpieces is improved, and processing cost is reduced.
Description
Technical field
The present invention relates to a kind of machining and use servicing unit, stationary fixture is used in especially a kind of processing, belongs to machining and uses the fixture technical field.
Background technology
Along with development of science and technology, more and more industries are in order to satisfy growing demand, all towards mass, the big production development of automation.But for mechanical processing industry, because the required precision of workpiece to be processed, and reason such as workpiece to be processed self shape, make mechanical part add man-hour, still single processing work on machine.And production firm will satisfy the big production of mass, just must increase the quantity of machine.So not only increased costs such as a lot of equipment, manpower, occupation of land space, and working (machining) efficiency is not high yet.In addition, each the workpiece accuracy error that processes is all different, if need use two workpiece on machine or the equipment, the error after the assembling also can be bigger so, the serious operation or the service life that also will influence machine.
Summary of the invention
Technical problem to above-mentioned existence the objective of the invention is: proposed a kind of processing and used stationary fixture, it can once fix two workpiece of processing, has improved working (machining) efficiency, has also guaranteed the uniformity of two workpiece that time processing goes out.
Technical solution of the present invention is achieved in that a kind of processing uses stationary fixture, comprises clamp body, mandrel, briquetting and nut; The end face of said clamp body has the storage tank of place work piece; Said mandrel bottom is fixed in the storage tank, and is positioned at the center of storage tank; The diameter of said mandrel is decided according to the diameter of bore of workpiece to be processed; Be with two workpiece on the said mandrel, and the face to be processed of two workpiece is close to; Said briquetting is positioned at the mandrel top, and the briquetting top is provided with nut; Said nut sleeve is on the mandrel top, and nut compresses briquetting two workpiece all are fixed on the clamp body.
Preferably, have a plurality of through holes on the said briquetting; Said through hole is corresponding with the hole to be processed on the workpiece to be processed.
Preferably, in the through hole on the said briquetting, be equipped with pin; In the workpiece to be processed below the bottom insertion of said pin.
Preferably, said clamp body is a rectangle.
Preferably, said clamp body is circular, and storage tank is positioned at the center of clamp body.
Because the utilization of technique scheme, the present invention compared with prior art has advantage:
Stationary fixture is used in processing of the present invention, and it is fixed on two workpiece on the clamp body through briquetting and nut with pasting mutually; Then with the clamp body clamping to the workbench of lathe or on the chuck; Process, once two workpiece of while clamping have guaranteed the uniformity that workpiece is processed; And improved workpiece efficient, reduced processing cost.
Description of drawings
Below in conjunction with accompanying drawing technical scheme of the present invention is described further:
Accompanying drawing l is the user mode stereogram of processing of the present invention with stationary fixture;
Accompanying drawing 2 is the cutaway view of accompanying drawing 1;
Wherein: 1, clamp body; 2, storage tank; 3, workpiece; 4, briquetting; 5, mandrel; 6, pin; 7, nut; 8, through hole; 9, locating hole.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is described.
Accompanying drawing 1,2 is that stationary fixture is used in a kind of processing of the present invention, comprises clamp body 1, mandrel 5, briquetting 4, pin 6 and nut 7; Said clamp body 1 is a rectangle, and has the storage tank 2 of place work piece 3 on the end face of clamp body 1; Said mandrel 5 bottoms are fixed in the storage tank 2, and are positioned at the center of storage tank 2; The diameter of said mandrel 5 is identical with the internal diameter of workpiece 3; Be with two workpiece 3 on the said mandrel 5, and the face to be processed of two workpiece 3 is close to; Said briquetting 4 is positioned at mandrel 5 tops, and briquetting 4 tops are provided with nut 7; Said nut 7 is enclosed within mandrel 5 tops, and nut 7 compresses briquetting 4 two workpiece 3 all are fixed on the clamp body 1; Have a plurality of through holes 8 on the said briquetting 4; Need the locating hole 9 of processing corresponding on said through hole 8 and the workpiece 3; In the through hole 8 on the said briquetting 4, be equipped with pin 6; In the workpiece 3 below the bottom insertion of said pin 6.
During processing work, at first to be processed with two workpiece fits each other, and all is enclosed within workpiece on the mandrel; At this moment, the workpiece lower end that is arranged in the below just has been placed on the storage tank of clamp body, then briquetting is inserted on the mandrel; And through the nut screwing clamping briquetting, make two workpiece press and be fixed on the clamp body, directly clamp body is fixed on the drilling machine; Through hole on the briquetting just has been equivalent to the drill bushing of drill bit, and is more convenient, accurately workpiece has been carried out bore operation; After accomplishing boring; Directly clamp body is fixed on other lathes, in through hole, inserts pin, make the pin bottom be inserted in the locating hole that the below workpiece processes; Guaranteed the uniformity of two workpiece processing more; When having improved workpiece processing uniformity, also improve working (machining) efficiency, saved a lot of times.
The foregoing description only is explanation technical conceive of the present invention and characteristics; Its purpose is to let the personage that is familiar with this technology can understand content of the present invention and implements; Can not limit protection scope of the present invention with this; All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
