Description

Driven shaft milling key groove positioning tool

Technical field

The utility model relates to axle type clamping field of locating technology, particularly a kind of driven shaft milling key groove positioning tool.

Background technology

Need a plurality of keyways of processing on the driven shaft, its size and position accuracy demand are high.Add the traditional V-type locating piece of many employings in man-hour at present, this type of locating piece exists no axial location function, and the location area of axle is little; Locate insecurely, be prone to rotate, problem such as axial float, increased the keyway difficulty of processing; Influence the keyway crudy, restricted the raising of working (machining) efficiency.

The utility model content

The purpose of the utility model is to overcome the shortcoming of prior art, provides that a kind of clamping is stable, firm position, driven shaft milling key groove positioning tool with axial location function.

The purpose of the utility model realizes through following technical scheme:

Driven shaft milling key groove positioning tool, it comprises supporting seat and gland, and supporting seat comprises body A, and the upper surface of body A is provided with locating surface A, and locating surface A is spill arc surface, respectively is provided with a bolt hole on the body A of locating surface A both sides; Gland comprises body B, and the lower surface of body B is provided with locating surface B, and locating surface B is a last spill arc surface that matches with locating surface A, respectively is provided with a through hole B on the body B of locating surface B both sides; Gland is located on the supporting seat, and screw rod passes through hole B, is installed in the bolt hole, and the screw rod upper end is equipped with nut.

The body A of described locating surface A below is provided with two horizontal flanges, and horizontal flange is provided with through hole A.

Described body A lower surface also is provided with a cup head flat key.

The utlity model has following advantage:

The utility model adopts the circular arc locating surface to replace original V-arrangement locating surface, has increased the contact area of positioning tool with axle, and has been provided with the tie down screw structure; Make positioning tool be coupling touch tightr; Restraining force improves greatly, makes the positioning tool clamping stable, firm position; The supporting seat lower surface of positioning tool be provided with platen on the cup head flat key that cooperates of T type groove, make be positioned at collinear several keyways on the driven shaft can disposable processed completion, and can guarantee that these keyways are located along the same line.Therefore the utility model had both improved the working (machining) efficiency of driven shaft keyway, had also improved the crudy of keyway.
