Problems solved by technology

[0003] However, since the size of the bearings in the watch is very small (usually around 1 mm), the requirements for machining accuracy are very high.
Especially in some cases, it is required to process the inner hole of the jewel bearing into a variable-diameter inner hole whose generatrix is ​​an arc, and ordinary processing methods are difficult to meet the demand

Embodiment

[0041] Such as figure 1 and figure 2 As shown in Fig. 1, a device for processing arc-shaped inner holes of watch jewel bearings, including a guide wheel mechanism and a feeding mechanism.

[0042] Wherein, the guide wheel mechanism includes a guide wheel 1 and a grinding steel wire 2 .

[0043] The guide wheel 1 is cylindrical, and the side of the guide wheel 1 is provided with a guide wheel spiral groove; the guide wheel spiral groove takes the axis of the guide wheel 1 as the axis and spirally surrounds the side of the guide wheel 1, and the cross section of the guide wheel spiral groove is consistent with the jewel bearing to be processed. 3 to match the shape.

[0044] One side of the gemstone bearing 3 to be processed is stuck in the spiral groove of the guide wheel, and a grinding steel wire 2 is passed through the inner hole of the gemstone bearing 3 to be processed; the grinding steel wire 2 presses the gemstone bearing 3 to be processed into the spiral groove of th...

Abstract

The invention discloses a watch jewel bearing bore arc processing device, which comprises a feeding mechanism and a tightening mechanism, which are arranged at the two ends of a guide wheel mechanism respectively. The guide wheel mechanism comprises a guide wheel and a grinding steel wire. The side surface of the guide wheel is provided with a guide wheel spiral groove. One side of a jewel bearing to be processed is clamped in the guide wheel spiral groove. The grinding steel wire passes through a bore of the jewel bearing to be processed. The feeding mechanism comprises a feeding feeder, a jewel bearing limiter and a feeding end steel wire tightening support. The feeding feeder comprises a feeding push plate, a feeding screw rod and a balance guide bar. The feeding push plate is arranged on a slide block. One end of the feeding push plate is suspended, and the suspended end of the feeding push plate is provided with a bent arc plate. The slide block is internally provided with the feeding screw rod and the balance guide bar. When the feeding screw rod rotates, the slide block is driven to reciprocate along the balance guide bar. The grinding steel wire presses the bore of the jewel bearing to be processed, and grinds the bore wall of the bore of the jewel bearing to be processed, and thus the device can process the jewel bearing accurately and quickly.

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 (commonly known as: watch drills) to improve the service life of the watch and ensure the stability of the mechanical transmission inside the watch. [0003] However, since the bearings in watches are very small in size (usually around 1 mm), the requirements for machining accuracy are very high. Especially in some cases, it is required to process the inner hole of the jewel bearing into a variable-diameter inner hole whose generatrix is ​​an arc, and ordinary processing methods are difficult to meet the demand. [0004] Therefore, there is an urgent need to develop a processing device that can increase the processing speed and ensure the...
