Abstract

The utility model aims to provide a positioning device without secondary positioning and adjustment. The positioning device comprises a positioning body and a positioning base connected with each other optionally up and down, the positioning body is connected with a work piece needs to be machined, the positioning base is connected with a machine tool, a clamping surface is arranged on the positioning body, fixed teeth are arranged on the clamping surface, a positioning screw is arranged on the opposite surface of the clamping surface, and the work piece is fixedly positioned by the positioning body through the clamped assembly of the positioning screw and the fixed teeth. The positioning device realizes the fixation of the work piece and the positioning body through the positioning screw and the fixed teeth, realizes convenient and firm positioning, avoids the secondary positioning adjustment of the work piece, improves the work efficiency and avoids the malposition situation.

Description

A kind of positioner

Technical field

The utility model relates to a kind of positioner.

Background technology

In existing part processing, electrode processing, what have directly is fixed on workpiece to be processed on the machining tool; The backing plate that passes through that has is fixed on the machining tool.If in the process of processing, workpiece need be taken off carry out other operation after, be placed on again on the machining tool, need once more the location to adjust, have the defective that the location is inaccurate, wasted the time simultaneously.

The utility model content

The purpose of this utility model is to disclose a kind of positioner that does not need the secondary location to adjust.

Positioner described in the utility model, comprise and can select up and down the location body and the positioning base that connect, the location body links to each other with workpiece to be processed, positioning base links to each other with machining tool, the location body is provided with clamping face, be provided with fixed teeth on clamping face, be provided with dog screw on the opposite face of clamping face, the location body is by the stationary positioned that realizes workpiece that clamps of dog screw and fixed teeth.

Wherein, the location upper part of body is the cavity that cylindrical inside is square for the outside, and clamping face is arranged on four planes of vertical level in the cavity.

Wherein, clamping face is two, and these two clamping face next-door neighbours are provided with.

Wherein, the location upper part of body is spill, and clamping face and dog screw are separately positioned on two end faces of projection.

Wherein, clamping face and dog screw are respectively four.

Wherein, be provided with positioning jack in positioning base, be provided with dowelled spanner in the outside of positioning base, the bottom of location body is provided with insertion end, and the location body inserts locating hole by insertion end and positioning base is realized positioning and fixing.

Wherein, be provided with four location balls in the positioning jack, insertion end is cylindrical, and when insertion end was inserted positioning jack, dowelled spanner can inwardly press the location ball fixedly secured positioning base and insertion end.

Wherein, machining tool is Digit Control Machine Tool CNC.

The utility model is realized the fixing of workpiece and location body by dog screw and fixed teeth, and the location is convenient, firm, has avoided the secondary location of workpiece to adjust, and has improved operating efficiency, and can not produce dislocation.

The specific embodiment

Below in conjunction with accompanying drawing, a specific embodiment of the present utility model is described in detail, but is to be understood that protection domain of the present utility model is not subjected to the restriction of the specific embodiment.

As shown in Figure 1-Figure 3, positioner of the present utility model comprises location body and positioning base, and the bottom of location body is provided with insertion end 4, and positioning base is provided with positioning jack 5, in positioning jack 5, be provided with four location balls, be provided with dowelled spanner 6 in the outside of positioning base.

The location upper part of body is that an outside is the cavity that cylindrical inside is square, and the two adjacent surfaces of the wall vertical with horizontal plane of cavity is provided with clamping face, and clamping face is provided with fixed teeth 2, is respectively equipped with dog screw 3 on the two sides relative with clamping face.

When the user uses this positioner, workpiece to be processed 1 is put into cavity, screwed in place screw 3, make workpiece 1 being installed between dog screw 3 and the fixed teeth 2 tightly, insertion end 4 is put into positioning jack 5, pull dowelled spanner 6, make the location ball insertion end 4 being fixed up tightly, then positioning base is fixed on machining tool particularly Digit Control Machine Tool (Computernumber control, CNC) on.

As Fig. 4-shown in Figure 6, different with embodiment one, the top of the fixed body of embodiment two is the spill setting, four groups of clamping faces and dog screw 3 are separately positioned on two end faces of projection, clamping face is provided with fixed teeth 2, and other parts are identical with being provided with of embodiment one, do not repeat them here.

In the utility model, if in the process of processing, workpiece need carry out other operation, can insertion end be unclamped from positioning jack by dowelled spanner, positioning base can separate with the location body, workpiece is carried out other operation with the location body is related, behind the EO, insertion end is put into positioning jack, positioning base and location body are fixed up, can continue workpiece is processed, needn't carry out the secondary location, for example avoid playing the operation of showing, accurate positioning in the branch once more to workpiece, fixation has improved operating efficiency, and can not produce dislocation.

More than disclosed only be a specific embodiment of the present utility model, still, the utility model is not limited thereto, any those skilled in the art can think variation all should fall into protection domain of the present utility model.
