Abstract
The invention discloses a metric/inch turning conversion device. The metric/inch turning conversion device comprises a lathe and a gearbox and further comprises a rotating shaft, a metric gear and an inch gear. The rotating shaft is located at the lower end of the gearbox, and the rotating shaft and the gearbox are rotatably connected. The metric gear penetrates through the rotating shaft, and the metric gear and the rotating shaft are rotatably connected. The inch gear penetrates through the rotating shaft, and the inch gear and the rotating shaft are rotatably connected. According to the metric/inch turning conversion device, compared with the prior art, the purpose of metric/inch conversion is achieved by installing the gears of different dimensions on the rotating shaft, when a metric part is turned, transmission is conducted through the metric gear with 120 teeth and other gears, when an inch part is turned, the metric gear is disengaged from a traditional gear system, the inch gear with 127 teeth enters the transmission system, positioning can be achieved through nuts, and in this way, the effect of accurate machining can be achieved without conversion.
Description
Technical field
The present invention relates to a kind of reforming unit, particularly relate to a kind of metric and English turning reforming unit.
Background technology
Along with the fusion development of technical field; drawing made in Great Britain is often there will be in Tutrning Process; traditional processing method carries out conversion processing according to 1in=25.4mm formula; but 25.4 numerical value are estimated values; accuracy is not high; directly can affect the precision of turning part size, in view of above-mentioned defect, be necessary to design a kind of metric and English turning reforming unit in fact.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of metric and English turning reforming unit, solves metric and English conversion and causes the problem that turning accuracy is not high.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of metric and English turning reforming unit, comprise lathe and gearbox, also comprise and rotate rotating shaft, metric system wheel, wheel made in Great Britain, described rotating shaft is positioned at gearbox lower end, and the two is rotationally connected, described metric system wheel is through rotating shaft, the two is rotatedly connected, and described English system wheel is through rotating shaft, and the two is rotatedly connected.
Further, described rotating shaft also runs through and has locking member, it is some nuts.
Further, described metric system wheel is also provided with 120 gear teeth.
Further, described English system wheel is also provided with 127 gear teeth.
Further, described metric system wheel center is also provided with clutch shaft bearing.
Further, described English system wheel center is also provided with the second bearing.
Compared with prior art, this metric and English turning reforming unit, the object of yard and meter turn is reached by gear rotating shaft again being installed different regulation, when turning metric system part, the metric system of 120 teeth wheel and other gears are used to carry out transmission, when turning part made in Great Britain, metric system wheel is departed from traditional gear system, the English system wheel being replaced by 127 teeth enters transmission system, by nut positioning instant can, the effect without the need to transforming accurately processing can be reached.

Following detailed description of the invention will further illustrate in conjunction with above-mentioned accompanying drawing.
Detailed description of the invention
Hereinafter, set forth multiple specific detail, to provide the thorough understanding to the concept forming described embodiment basis.But to one skilled in the art, embodiment described obviously can be put into practice when not have in these specific detail some or all.In other cases, well-known treatment step is not specifically described.
As Fig. 1, shown in Fig. 2, comprise lathe 1, gearbox 2, rotating shaft 3, metric system wheel 4, wheel 5 made in Great Britain, locking member 301, clutch shaft bearing 401, second bearing 501, rotating shaft 3 is positioned at gearbox 2 lower end, the two is rotationally connected, metric system wheel 4 is through rotating shaft 3, the two is rotatedly connected, wheel 5 made in Great Britain is through rotating shaft 3, the two is rotatedly connected, rotating shaft 3 also runs through and has locking member 301, it is some nuts, metric system wheel 4 is also provided with 120 gear teeth, wheel 5 made in Great Britain is also provided with 127 gear teeth, described metric system is taken turns 4 centers and is also provided with clutch shaft bearing 401, wheel made in Great Britain 5 centers are also provided with the second bearing 501, this metric and English turning reforming unit, the object of yard and meter turn is reached by the gear installing different regulation on rotating shaft 3, when turning metric system part, the metric system of 120 teeth wheel 4 and other gears are used to carry out transmission, when turning part made in Great Britain, metric system wheel 4 is departed from traditional gear system, the English system wheel 5 being replaced by 127 teeth enters transmission system, can by nut positioning instant, the effect without the need to transforming accurately processing can be reached.
The present invention is not limited to above-mentioned concrete embodiment, and those of ordinary skill in the art is from above-mentioned design, and without performing creative labour, all conversion made, all drop within protection scope of the present invention.
