Nondestructive testing device in manufacturing process

Abstract

The invention discloses a nondestructive testing device in the manufacturing process. The nondestructive testing device comprises a fixed bottom plate; a numerical control case is arranged on the upper end face of the fixed bottom plate, and the fixed bottom plate and the numerical control case are of an integrated structure; a clamp is arranged in a clamp groove; the middle of the upper end faceof the clamp is fixedly connected with a conical shaft; the upper side of the conical shaft is sleeved with an expanding sleeve; a hob module is fixedly arranged at the left end inside a machining space; and the left end of a telescopic rod penetrates out of the left end wall of a telescopic space and a telescopic groove to be fixedly connected with a span ranging testing device. During working ofthe nondestructive testing device, it is guaranteed that the expanding sleeve can be uniformly expanded towards the periphery through a partition groove, the coaxiality is guaranteed, the accuracy requirement in the machining process is guaranteed, the measurement angle is automatically adjusted, and the accuracy of the measurement value is guaranteed; and in the measurement process, workpieces during machining do not need to be removed, the tooth rotting phenomenon caused by repeated clamping is avoided, machining raw materials are saved, and technical controllability is improved.

Description

technical field [0001] The invention relates to the field of processing process control, in particular to a non-destructive testing device in the manufacturing process. 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.

[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.
