The invention discloses a fixing clamp. The fixing clamp is composed of a male clamp base, a female clamp base and a locating connection block. A plurality of arc grooves are formed in the upper surface of the male clamp base. A cylinder is arranged at the left end of the male clamp base. The cylinder and the male clamp base are integrated. A locating hole I is formed in the middle of the male clamp base. Triangular tooth tops for fastening a workpiece are arranged at the right end of the male clamp base. A round hole matched with the cylinder arranged at the left end of the male clamp base is formed in the right end of the female clamp base. A locating hole II is formed in the middle of the female clamp base. A locating hole III is formed in the middle of the locating connection block. According to the technical scheme, the fixing clamp is simple in structure, reasonable in design, convenient to clamp, and capable of improving work efficiency and reducing cost. By the adoption of the fixing clamp, one-off machining can be conducted on the surface of the workpiece, and the machining quality and the machining accuracy of the workpiece are guaranteed.

Description

A kind of stationary fixture

Technical field

The invention belongs to Fixture designing, specifically the workpiece of needs processing is fixed on to a kind of stationary fixture on platen.

Background technology

Being carried out to milling, plane, polishing etc., the surface of workpiece adds man-hour, the workpiece of needs processing must be fixed on the workbench of lathe, and the fixing fixture that all adopts of existing workpiece, fixture is when fixation workpiece, at present all need fixture to be fixed on the surface of workpiece, and then workpiece is processed, like this, adding man-hour, the fixture on surface of the work is just to being processed to form interference.On the one hand, fixture is when surface of the work clamps, and workpiece produces workpiece that slight deformation, especially area are large and thin and adding man-hour and more easily cause the damage of workpiece because be stressed; On the other hand, fixture is placed on surface of the work, owing to cannot the surface of the work of placing clamp being processed, just must first in the impregnable part of surface of the work, process, then, then change the position of fixture, other parts of workpiece are processed, like this, to workpiece, can not carry out comprehensive disposable processing, will cause lower compressive strain to workpiece, displacement connects cutter out-of-flatness, working (machining) efficiency is low, cannot guarantee the crudy of workpiece.

Summary of the invention

The object of the present invention is to provide a kind of stationary fixture, this clamp structure is simple, reasonable in design, and convenient mounting and clamping has improved operating efficiency, has reduced cost, can carry out disposable processing to surface of the work, has guaranteed crudy and the machining accuracy of workpiece.

For achieving the above object, a kind of stationary fixture of the present invention, is characterized in that: this stationary fixture comprises male clamping fixture seat, female clamping fixture seat and the piece that is located by connecting; The upper surface of described public clamping fixture seat is provided with the groove of a plurality of arcs, at the left end of public clamping fixture seat, is provided with cylinder, and cylinder and public clamping fixture seat are an integral body, in the centre of public clamping fixture seat, are provided with locating hole I, are provided with the triangle crown of fastening workpiece at the right-hand member of public clamping fixture seat; Described female clamping fixture seat and male clamping fixture seat match, and at the right-hand member of female clamping fixture seat, are provided with the circular port that the cylinder with male clamping fixture seat left end matches, and in the centre of female clamping fixture seat, are provided with locating hole II; The semicircle of the described piece bottom that is located by connecting is corresponding with the shape of groove on public clamping fixture seat, and the length of the piece that is located by connecting is corresponding with the length of public clamping fixture seat upper surface groove, in the centre of the piece that is located by connecting, is provided with locating hole III.

In technique scheme, surface of the work is being added to man-hour, workpiece is placed on platen, and a plurality of stationary fixtures of the present invention is fixed the two side ends of workpiece by the bolt being fixed on platen simultaneously.During sectional fixture, formerly the cylinder on male clamping fixture seat is inserted in the circular port on female clamping fixture seat, with bolt, insert and to female clamping fixture seat, position fixing in the middle locating hole II of female clamping fixture seat again, then, public clamping fixture seat is placed on to the side of workpiece with one side of triangle crown, by bolt, by the piece that is located by connecting, inserted in the locating hole I in the middle of public clamping fixture seat again, rotation bolt, the stationary fixture by workpiece two side ends is fixed workpiece.Stationary fixture of the present invention in use has following advantage: the first, and clamp structure is simple, reasonable in design, convenient mounting and clamping; Second, when fixation workpiece, at the fixing a plurality of fixtures of side of workpiece, stationary fixture is not to be fixed on the surface of workpiece, is to push workpiece by tensioner simultaneously, not only can effectively prevent the distortion of workpiece, and can guarantee surface of the work to carry out disposable machining, do not need movable clamp, improved operating efficiency, reduce cost, guaranteed crudy and the machining accuracy of workpiece.

The specific embodiment

Below in conjunction with accompanying drawing, a kind of stationary fixture of the present invention is described in further detail.

From Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8, a kind of stationary fixture of the present embodiment is comprised of male clamping fixture seat 1, female clamping fixture seat 2 and the semicircular piece 3 that is located by connecting.The upper surface of public clamping fixture seat 1 is provided with the groove 4 of a plurality of arcs, left end at public clamping fixture seat 1 is provided with cylinder 5, cylinder 5 is an integral body with public clamping fixture seat 1, in the centre of public clamping fixture seat 1, is provided with locating hole I 6, is provided with the triangle crown 7 of fastening workpiece at the right-hand member of public clamping fixture seat 1.Female clamping fixture seat 2 matches with male clamping fixture seat 1, at the right-hand member of female clamping fixture seat 2, is provided with the circular port 8 that the cylinder 5 with male clamping fixture seat 1 left end matches, and in the centre of female clamping fixture seat, is provided with locating hole II 9.The semicircle of piece 3 bottoms that is located by connecting is corresponding with the shape of groove 4 on public clamping fixture seat 1, and the length of the piece 3 that is located by connecting is corresponding with the length of public clamping fixture seat 1 upper surface groove 4, in the centre of the piece 3 that is located by connecting, is provided with locating hole III 10.In the present embodiment, upper surface at public clamping fixture seat 1 has a plurality of arc grooves 4, and on public clamping fixture seat 1, locating hole I 6 is holes of a long waist shaped, and object is according to varying in size to workpiece fixed position and workpiece, and convenience running fix bolt in locating hole I 6, convenient location.
