Process detecting device used in machine manufacturing

Abstract

The invention discloses a process detecting device used in machine manufacturing. The process detecting device comprises a fixed base plate, a numerical control machine case is arranged on the upper end face of the fixed base plate, the numerical control machine case and the fixed base plate are of an integrated structure, a clamp body is arranged in a clamp groove, a taper shaft is fixedly connected to the middle position of the upper end face of the clamp body, the upper side of the taper shaft is sleeved with an expanding sleeve, a hob module is fixedly arranged at the left end of the interior of a machining space, and the left end of a stretchable rod penetrates out of the left end wall of a stretchable space and a stretchable groove and is fixedly connected with an across-measured distance detecting device. When the process detecting device works, a dividing groove guarantees that the expanding sleeve can expand towards the periphery evenly, the coaxality is guaranteed, the accuracy requirement in the machining process is guaranteed, the measurement angle is automatically adjusted, and the accuracy of a measurement value is guaranteed; and in the measurement process, workpieces in machining do not need to be detached, tooth breaking caused by repeated clamping is avoided, machining materials are saved, and the technological controllability is increased.

Description

technical field [0001] The invention relates to the field of processing process control, in particular to a process detection device in mechanical manufacturing. Background technique [0002] At present, in the field of gear processing, gear hobbing is the most important link, which directly affects the progress of subsequent processes. In the process of gear hobbing, the span distance of hobbing will change due to the influence of machine tool accuracy and temperature. , At this time, it is necessary to re-measure the span distance and then adjust the program according to the span distance measurement. It is difficult to complete the adjustment process in one step, and it needs to be debugged step by step. After the hobbing is clamped, due to the reason of the measuring ball, It is necessary to remove the workpiece from the fixture for measurement, because repeated clamping will cause rotten teeth and knife damage. Generally, unqualified workpieces cannot be processed and t...

[0002] At present, in the field of gear processing, gear hobbing is the most important link, which directly affects the progress of subsequent processes. In the process of gear hobbing, the span distance of hobbing will change due to the influence of machine tool accuracy and temperature. , At this time, it is necessary to re-measure the span distance and then adjust the program according to the span distance measurement. It is difficult to complete the adjustment process in one step, and it needs to be debugged step by step. After the hobbing is clamped, due to the reason of the measuring ball, It is necessary to remove the workpiece from the fixture for measurement, because repeated clamping will cause rotten teeth and knife damage. Generally, unqualified workpieces cannot be processed and tested again, which wastes resources, and there are also cases where the workpiece is not removed for measurement. The method is to smear butter on the measuring ball, so that the measuring ball is absorbed in the tooth surface. This measurement method is difficult to operate and the measurement is not accurate.
