Watch jewel bearing inner hole arc-shaped machining device

Abstract

The invention discloses a watch jewel bearing inner hole arc-shaped machining device. The device structurally comprises an adjusting micro-drill base,a micro-drill disassembling shaft,a bearing fixingand converting device,an operating table,a supporting foot frame and a rotary braking box body. Based on the prior art,fixing and angle changes of bearings are controlled through machines,and small watch bearings can be well fixed under the action of magnetism and limiting; under the action of the rotary braking box,bearing inner holes can be well machined; by means of a rotation control device,the machining angle of the bearing is driven,parts do not need to be disassembled,and therefore the workload is reduced; a sliding mechanism and a transmission mechanism are driven by an electric agentbraking device and finally act on a horizontal moving structure,the horizontal moving effect of the bearings can be achieved,the maneuverability during machining is improved,and the occurrence of jamming is prevented; the device improves the speed and quality of bearing inner hole machining,and a good fixing effect is achieved.

Description

technical field [0001] The invention relates to the technical field of watch manufacturing, in particular to a device for processing arc-shaped inner holes of watch jewel bearings. Background technique [0002] In mechanical watches, high-hardness artificial gemstones are usually used to manufacture bearing shafts and other easy-wear parts to improve the service life of the watch and ensure the stability of the mechanical transmission inside the watch. Due to the small size of the watch bearing and the relatively fine inner hole requirements, Existing processing devices cannot guarantee the accuracy of processing, and it is difficult to meet the requirements. The existing technology usually uses mechanical methods such as micro-drilling for processing. However, due to the small size of the watch bearing, it is difficult to control the bearing fixing device. The inner hole is deformed or even damaged, which reduces the processing speed and yield.
