Description
Technical Field
The invention belongs to the technical field of turning clamping tools, and particularly relates to an axial positioner for turning shaft workpieces.
Background
During the turning process, shaft parts are the most common type of machining. When the shaft workpiece is turned, particularly longer parts, the length of the workpiece extending out of the clamping jaw can only be measured through a steel plate ruler or a depth caliper, but the workpiece is easy to axially move in the clamping process of the clamping jaw, so that the extending length of the machined part cannot be accurately controlled, and the front end cannot be accurately positioned. Or the tail seat is locked, the tail seat handle is rocked back and forth to repeatedly position in a scale observation mode, time and labor are wasted, and scales are easy to shake. Therefore, the common practice is to leave a margin for the dimension of the shaft part in the length direction, and after the other dimensions of the part are processed, the length dimension is processed to the technical requirement. The disadvantages of the above process are: (1) the process flow is long; (2) the end face of the part needs to be processed for a plurality of times; (3) Because the total length of the part is finally processed, the correlation of the sizes of other length directions is considered, the measurement is difficult, and the size out-of-tolerance is easy to occur; (4) The processed surface needs to be clamped for many times, surface scratches are easy to cause, and the surface quality problem occurs.
