Connecting mechanism for indexing of machine tool angle head with indexing value being 5 degrees

Abstract

The invention relates to a connecting mechanism and method for indexing of a machine tool angle head with the indexing value being 5 degrees. The connecting mechanism comprises the angle head, a cylindrical indexing device and a machine tool spindle, wherein the cylindrical indexing device is fixed to the machine tool spindle, the angle head is connected with the cylindrical indexing device in the circumferential direction, cylindrical indexing bosses with the indexing value of 5 degrees are evenly distributed on the end face of the angle head, and an indexing transmission device in the cylindrical indexing device rotates under the action of external force and drives the angle head to rotate through cylindrical indexing bosses. According to the connecting mechanism, the whole circle of 360-degree rotary positioning work with the indexing value of 5 degrees of the angle head can be completed, the connecting mechanism is particularly suitable for the situation that the angle of the angle head needs to be adjusted for multiple times during one-time clamping, the problem that the machining efficiency is reduced due to the fact that the angle is confirmed through meter punching is solved, the fatigue feeling and misoperation of workers due to repeated meter punching and alignment are avoided, and the processing efficiency and the processing precision are improved.

[0002] In the field of mechanical processing, the main shaft of a three-axis horizontal milling machine is usually parallel to the horizontal plane. Due to the structure of the workpiece, it is necessary to process features such as planes and holes in the workpiece cavity. When processing these features, it is necessary to add a new machining axis perpendicular to the main shaft. To achieve the goal, in the case of cost saving, the angle head is usually used to expand the processing range of the machine tool. The most commonly used is the 90° right-angle angle head. This angle head can freely adjust the angle in the direction of rotation of the spindle. To process planes, holes and other structures with different angles, after adjusting the angle, clamp the long rod on the right-angle head, and then check the straightness of the long rod with a meter, to indirectly confirm the error of the angle after rotation, when one clamping needs multiple times When adjusting the angle of the angle head, it takes too long to make a meter each time, and the accuracy of adjusting the angle is low, resulting in knife marks and dimensional errors on the processing surface, which increases the labor intensity of the workers, and easily causes the workers to feel tired and lead to work emotions. Low, reducing the processing efficiency
