Abstract
The invention discloses an L-shaped clamp for a milling machine, belonging to the field of machine tool clamps. The L-shaped clamp comprises a clamp base, a sliding track, an adjusting screw rod, a moving block and a clamping block, wherein the lower end of the sliding track is arranged on the clamp base, and the upper end of the sliding track presses a concave edge in the lower end of the moving block; the lower end of the clamping block presses a concave edge in the upper end of the moving block; the adjusting screw rod is meshed with the moving block; stairs are arranged at the lower end of a clamping surface of the clamping block; the clamping block is L-shaped along the vertical sectioning direction. The L-shaped clamp solves the problems that a conventional clamp is likely to axially play and to damage a workpiece because of large axial clamping force when being used for clamping the workpiece; the L-shaped composite clamp has the advantages of simple structure, reasonable design, and easiness in manufacturing.
Description
Technical field
The invention belongs to the jig field, more particularly, relate to a kind of fixture for milling machine.
Background technology
In machine industry, lathe is widely used in processing all kinds of parts, is adding man-hour, need to as locating surface, carry out the machining such as cylindrical, end face, screw thread and axial cut-out with end face or endoporus.But for inside workpiece, add man-hour, play, owing to only being subjected to radially chucking power, axially easily occurs in workpiece.If strengthen radially chucking power, axial float can be resolved to a certain extent, but is faced with the possibility of crushing workpiece.Therefore, a kind of fixture for the workpiece axial restraint of necessary design.
Summary of the invention
During for existing fixture holding workpiece, the problem of axially easy play, the excessive easily damaged workpiece of radial clamping power, the invention provides the L shaped fixture of a kind of milling machine.
For addressing the above problem, the present invention adopts following technical scheme.
The L shaped fixture of a kind of milling machine, comprise clamping fixture seat, slide rail, adjusting screw(rod), movable block and clamp, and the lower end of described slide rail is arranged on clamping fixture seat, and the upper end of slide rail is pressed on the recessed edge in movable block lower end; Described clamp lower end is pressed on the recessed edge in upper end of movable block; Described adjusting screw(rod) is meshed with movable block; The clamping area lower end of described clamp is provided with step, and clamp vertically sectional shape is L-shaped.
On the step of described clamp, inlay one deck carbide alloy.
Than prior art, beneficial effect of the present invention is:
(1) the clamping area lower end of clamp of the present invention is provided with step, and it can prevent that workpiece from adding the axial float in man-hour.
(2) the present invention, after on the clamping area of clamp, step being set, can reduce radially chucking power to a certain extent, has reduced the damage to surface of the work.
(3) the present invention is simple in structure, reasonable in design, is easy to manufacture.
The accompanying drawing explanation
Fig. 1 is front view of the present invention;
Fig. 2 is top view of the present invention.
In figure: 1-slide rail, 2-adjusting screw(rod), 3-movable block, 4-clamp.
The specific embodiment
Below in conjunction with accompanying drawing, describe the present invention.
As shown in Figure 1 and Figure 2, the L shaped fixture of a kind of milling machine, comprise clamping fixture seat, slide rail 1, adjusting screw(rod) 2, movable block 3 and clamp 4, and the lower end of described slide rail 1 is arranged on clamping fixture seat, and the upper end of slide rail 1 is pressed on the movable block 3 recessed edge in lower end; Described clamp 4 lower ends are pressed on the recessed edge in upper end of movable block 3; Described adjusting screw(rod) 2 is meshed with movable block 3; The clamping area lower end of described clamp 4 is provided with step, and clamp 4 vertically sectional shape is L-shaped.On the step of clamp 4, inlay one deck carbide alloy.
In use, by rotation adjusting screw(rod) 2, movable block 3 is under the effect of adjusting screw(rod) 2, promoting slide rail 1 slides to centre on clamping fixture seat, thereby the clamping of moving and complete that drives clamp 4 is moved, now side surface of workpiece matches with the clamping area of clamp 4, and the workpiece lower end is pressed on the step of clamp 4, completes location.Otherwise counter-rotating adjusting screw(rod) 2 can loosen workpiece.
As shown in Figure 1 and Figure 2, the L shaped fixture of milling machine comprises clamping fixture seat, slide rail 1, adjusting screw(rod) 2, movable block 3, clamp 4, the lower end of slide rail 1 is arranged on clamping fixture seat, the upper end of slide rail 1 is pressed on the movable block 3 recessed edge in lower end, clamp 4 lower ends are pressed on the recessed edge in upper end of movable block 3, and adjusting screw(rod) 2 is meshed with movable block 3.
The clamping area lower end of described clamp 4 is provided with step, and clamp 4 vertically dissects L-shaped, inlays tungsten carbide base carbide alloy on the step of described clamp 4.
Claims (2)
1. L shaped fixture of milling machine, comprise clamping fixture seat, slide rail (1), adjusting screw(rod) (2), movable block (3) and clamp (4), it is characterized in that, the lower end of described slide rail (1) is arranged on clamping fixture seat, and the upper end of slide rail (1) is pressed on the recessed edge in movable block (3) lower end; Described clamp (4) lower end is pressed on the recessed edge in upper end of movable block (3); Described adjusting screw(rod) (2) is meshed with movable block (3); The clamping area lower end of described clamp (4) is provided with step, and vertically sectional shape is L-shaped for clamp (4).
2. the L shaped fixture of milling machine according to claim 1, is characterized in that, inlays one deck carbide alloy on the step of described clamp (4).
