Description
Technical Field
The utility model belongs to the technical field of T type groove processing, a T type groove milling cutter is related to.
Background
The T-shaped groove is an inverted T-shaped groove processed on the working surface of the cast iron platform or the wooden platform, and is mainly used for fixing a workpiece by matching with a bolt and a screw so as to carry out work such as welding or assembly. The processing steps of the T-shaped groove are generally as follows:
1) drawing a processing line on the end surface and the upper plane of a platform to be processed;
2) planing a straight groove on the platform by using a milling cutter or a grooving cutter;
3) and (4) planing grooves on the left side surface and the right side surface at the bottom of the straight groove by using a T-shaped milling cutter or an elbow cutter.
In the method, two types of cutters are used for planing the straight groove and the left and right side grooves respectively, so that the number of the cutters is increased, multiple tool changing and multiple tool setting operations are required, the operation is complicated, and the machining precision is influenced.
SUMMERY OF THE UTILITY MODEL
The object of the present invention is to provide a T-slot milling cutter for overcoming the above-mentioned drawbacks of the prior art.

The T-shaped groove can clamp the groove side edge base at the bottom of the groove without separating from the cutter bar, and the groove side edge is exposed out of the guide groove so as to plane the side face of the bottom of the straight groove.
Further, the sum of the lengths of the straight groove side edge and the groove side edge is smaller than the length of the guide groove, so that the groove side edge can keep a longer distance from the straight groove side edge when moving to the highest position, and the work of the straight groove side edge is prevented from being influenced.
Furthermore, an upper bolt hole and a lower bolt hole are formed in the guide groove, the distance between the upper bolt hole and the top of the guide groove is equal to the length of the groove side edge base, and the distance between the lower bolt hole and the bottom of the guide groove is equal to the length of the groove side edge base.
Furthermore, a bolt matched with the groove side edge base is arranged in the upper bolt hole or the lower bolt hole. When the groove side edge base moves to the highest position, the bolt is screwed into the upper bolt hole, and the bottom of the groove side edge base is limited and fixed; when the recess side sword base removed to the minimum, in bolt hole down with the bolt screw in, carry on spacing fixedly to the top of recess side sword base, guarantee job stabilization nature.
Furthermore, the length of the groove side edge is smaller than that of the straight groove side edge, so that grooves on the left side surface and the right side surface are planed at the bottom of the straight groove, and finally the T-shaped groove consisting of the grooves on the left side surface and the right side surface and the straight groove is obtained.
Furthermore, the cutter bar is also provided with chip removal grooves matched with the straight groove side edge and the groove side edge respectively, so that chips can be removed conveniently.
When the utility model is used for processing T-shaped grooves, the movable groove planing mechanism is firstly moved to the top of the guide groove, the bolt is screwed into the upper bolt hole, and the straight groove is planed on the platform to be processed by the straight groove side blade on the side of the cutter bar; then directly take out the bolt in the upper bolt hole, make the recess side sword move to the guide way bottom downwards, later screw in the bolt hole down, dig out the recess of left and right sides in straight flute bottom by the recess side sword, and need not to carry out the tool changing or tool setting operation.
Compared with the prior art, the utility model has the characteristics of it is following:
1) firstly, a straight groove is planed on a platform to be processed through a straight groove side blade on the side surface of a cutter bar, then grooves on the left side surface and the right side surface are planed at the bottom of the straight groove through a groove side blade, and finally T-shaped groove processing is realized without tool changing or tool setting operation, so that the operation is simplified, and the processing precision can be ensured;
2) the movable groove planing mechanism can slide up and down on the side face of the cutter bar along the guide groove, not only can keep away from the straight groove side blade when the straight groove side blade planes the straight groove and avoid interference on the straight groove side blade, but also can stretch into the bottom of the straight groove after the straight groove planing is finished so as to plane the groove on the left side face and the right side face of the bottom of the straight groove, and the reliability is good.
