The invention discloses a tool clamp comprising a tool clamp body, a center movable shaft, an expansion sleeve, an end face positioning block, an outer circle clamping jaw and a locking nut. A cavityis formed in the axis of the tool clamp body. Threads are arranged on the inner wall of the cavity. The center movable shaft is located in the cavity and is in pull rod threaded connection with tool clamp body through the threads. The expansion sleeve is arranged on the center movable shaft in a sleeving manner. The conical surface of the inner side of the expansion sleeve is attached to the conical surface of one end of the center movable shaft. The end face positioning block is arranged on the expansion sleeve in a sleeving manner. The outer circle clamping jaw is arranged on the end face positioning block. The locking nut is arranged on the outer circle clamping jaw in a sleeving manner. The conical surface of the outer circle clamping jaw is attached to the conical surface of the innerside of the locking nut. Compared with the prior art, by means of the tool clamp, dual clamping can be achieved for machined parts, and therefore the machined parts are not prone to deform in the machining process, and the machining precision can be effectively improved.
Description
technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a tooling fixture. Background technique [0002] Flexible splines are flexible gears, which generally have a thin-walled cup shape, a thin-walled cylindrical shape, or a flat embedded type. [0003] In the production process of flexsplines, for thin-walled cup-shaped and thin-walled cylindrical flexsplines, the minimum wall thickness is 0.1mm, which is easily deformed in the actual processing process. Processing deformation will cause the size of the flexspline to be unstable, thus affecting the flexspline. The processing accuracy is low, and the processing yield is low. Contents of the invention [0004] The application provides a fixture, which can solve the technical problem of low machining accuracy of flex splines in the prior art. [0005] Specifically, the present invention provides a tooling fixture, which includes a tooling fixture body, a central movab...
