High-precision expander inner taper machining device

Abstract

The invention discloses a high-precision expander inner taper machining device. The machining device comprises a base, an arc-shaped supporting plate, a sliding rod assembly, a fixing plate, a first fastening assembly, second fastening assemblies and an adjusting assembly, wherein the arc-shaped supporting plate is arranged on the base, the sliding rod assembly is in sliding connection with the arc-shaped supporting plate and slides in the arc direction of the arc-shaped supporting plate, the fixing plate is arranged on the arc concave side of the arc supporting plate and fixedly connected with the sliding rod assembly, a fixing hole is formed in the center of the fixing plate, sliding grooves are symmetrically formed in the top and the bottom of the fixing hole, the first fastening assembly comprises a plurality of threaded fastening clamping pieces, the second fastening assemblies are arranged on the side, away from the arc-shaped supporting plate, of the fixing plate and slidably arranged in the sliding groove, the adjusting assembly is arranged on the side, facing the arc-shaped supporting plate, of the fixing plate and used for controlling the two second fastening assemblies to slide in the sliding grooves at the same time. According top the machining device, stable machining of the inner taper of an expander can be achieved, operation is easy, and the machining precisionis high.

Description

technical field [0001] The invention relates to the technical field of mechanical parts processing, and more specifically relates to a high-precision tire-increasing inner taper processing device. Background technique [0002] At present, the tire expansion processing technology generally stays on the original processing method. Firstly, the outer circle of the tire expansion is supported by the three claws of the headstock of the internal grinding machine, and the inner taper of the outer circle and the end surface are finely ground. This kind of inner taper processing method has the advantages of simple operation. , Cost-saving advantages. [0003] However, with the gradual development of science and technology, the requirements for the precision of parts processing are getting higher and higher. Since the tire is a thin-walled part, it is easy to cause the inner taper and the outer circle to be out of center during processing, resulting in a decrease in machining accuracy...

Problems solved by technology

[0003] However, with the gradual development of science and technology, the requirements for the precision of parts processing are getting higher and higher. Since the tire is a thin-walled part, it is easy to cause the inner taper and the outer circle to be out of center during processing, resulting in a decrease in machining accuracy. Moreover, the traditional way of fixing tires does not have a stereotype effect on the outer wall of the tire, and problems such as deformation of the tire are prone to occur during the processing process, which greatly affects the processing accuracy.
