The positioning clamp comprises a bearing seat and positioning seats, wherein the bearing seat is provided with a cylinder section; the end face of the cylinder section is provided with a waist-shaped positioning table; the upper surface and the lower surface of the positioning table are respectively provided with a dovetail groove; the side wall and the bottom of each positioning seat are respectively provided with screw rods and a dovetail table; the dovetail tables are respectively located in the dovetail grooves. The positioning clamp is simple in structure, flexible and convenient to use, simple in clamping and high in processing precision.

Description

Line cutting positioning fixture

Technical field

The utility model relates to technical field of tooling clamps, relates in particular to for workpiece being carried out to the fixture of line cutting location.

Background technology

Workpiece 1 as shown in Figure 1, its bottom is with kidney-shaped portion 11, now need on the bottom surface of kidney-shaped portion 11, process rectangular channel, because it also has baroque two arc platforms 12, cannot use turner or milling processing, line cutting processing technology, as the conventional technique of field of machining, must accurately locate workpiece, otherwise not only can not process the satisfactory product of precision, also can cause irreparable damage, as workpiece is thoroughly scrapped etc.

Utility model content

The utility model, for above-mentioned shortcoming of the prior art, provides a kind of line cutting positioning fixture, and it is simple in structure, flexible and convenient to use, and clamping efficiency is high, and machining accuracy is high.

The technical scheme that the utility model adopts is as follows:

Line cutting positioning fixture, comprises load bearing seat and positioning seat; Load bearing seat is with cylindrical section, and the end face of cylindrical section is with kidney-shaped positioning table, and the upper and lower surface of positioning table is all with dovetail groove; The sidewall of positioning seat and bottom are respectively with screw rod and forked tail platform, and forked tail platform is positioned at dovetail groove.

The utility model has the advantage of: the cylindrical section end of load bearing seat arranges the positioning table matching with workpiece base apertures position workpiece is supported, on positioning table, dovetail groove is set simultaneously, make positioning seat in dovetail groove slidably, on positioning seat with screw rod, arc platform on workpiece can be clamped on the end face of cylindrical section, simple in structure, flexible and convenient to use, clamping efficiency is high, and machining accuracy is high.

The specific embodiment

Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described.

As shown in Figures 1 to 4, the utility model comprises load bearing seat 2 and positioning seat 3; Load bearing seat 2, with cylindrical section 21, adds man-hour, and cylindrical section 21 is convenient to clamping, the end face of cylindrical section 21 is with kidney-shaped positioning table 22, the bottom mounting hole of the dimensions of positioning table 22 and workpiece 1 measure-alike, can accurately locate it, and the upper and lower surface of positioning table 22 is all with dovetail groove 23; The sidewall of positioning seat 3 and bottom are respectively with screw rod 32 and forked tail platform 33, forked tail platform 33 is positioned at dovetail groove 23, forked tail platform 33 can move along dovetail groove 23, be convenient to the clamped position of the arc platform 12 on 32 pairs of workpiece 1 of adjusting screw(rod), rotary screw 32 can be clamped in arc platform 12 on the end face of cylindrical section 21;

Using method of the present utility model is as follows:

The first step, is clamped in cylindrical section 21 on load bearing seat 2 on lathe;

Second step, makes the mounting hole of workpiece 1 bottom match with positioning table 22;

The 3rd step, packs positioning seat 3 in the dovetail groove 23 on positioning table 22, and the forked tail platform 33 on positioning seat 3 is coordinated with dovetail groove 23;

The 4th step, the screw rod 32 on rotation forked tail platform 33, is clamped in the arc platform 12 on workpiece 1 on the end face of cylindrical section 21.

More than describing is to explanation of the present utility model, is not the restriction to utility model, and the utility model limited range, referring to claim, within protection domain of the present utility model, can be done any type of modification.
