Manual accurate-indexing right-angle milling head

Abstract

The invention relates to the technical field of right-angle heads of machine tools, and in particular relates to a manual accurate-indexing right-angle milling head. The manual accurate-indexing right-angle milling head comprises a ram, a pad, a mouse tooth disc, a spindle sleeve, a right-angle head box body, a machine tool spindle, a key block, a gear knife handle, a spiral bevel gear I, a spiral bevel gear II, a shaft, a clamping jaw and a pop rivet, wherein the ram is fixedly connected with the pad; the upper end of the mouse tooth disc is fixedly connected with the spindle sleeve, and the lower end of the mouse tooth disc is fixedly connected with the right-angle head box body; the machine tool spindle is connected with the key block; the gear knife handle is connected with the spiral bevel gear I; the spiral bevel gear I is connected with the spiral bevel gear II which is connected with the shaft; and the clamping jaw is arranged at the center of the machine tool spindle and is connected with the pop rivet. According to the manual accurate-indexing right-angle milling head, the positioning precision and the repeated positioning precision after a manual right-angle head is rotated are improved, the machining precision of the manual right-angle head is improved, the problem that the right-angle head is not concentric with the machine tool during assembly is solved, and meanwhile, the problem that a bearing of the right-angle head is easily rusted due to water is solved, therefore, the right-angle milling head is easy to use and popularize.

Description

technical field [0001] The invention relates to the technical field of a machine tool right-angle head, in particular to a manual precision indexing right-angle milling head. Background technique [0002] The existing right-angle head replacement method is manual replacement. Manual replacement of the right-angle head is for positioning in four 90o directions. There is no positioning measure in the other directions, only locking, resulting in low positioning accuracy and repeat positioning accuracy. At the same time, the right-angle head is concentric with the machine tool spindle It is difficult to guarantee that if the right angle is not properly stored when it is not in use, the bearing of the right angle head may have the risk of water ingress and rust, which shortens the service life of the bearing. Contents of the invention [0003] In order to overcome the disadvantages of low positioning and repeated positioning accuracy, difficulty in ensuring the concentricity of...
