Workpiece positioning and clamping device for thread cutting machine

The invention discloses a workpiece positioning and clamping device for a thread cutting machine, comprising a supporting seat with an inner cavity, a running mechanism arranged on the upper plane of the supporting seat and a drive mechanism arranged inside the cavity of the supporting seat. The running mechanism consists of two V-shaped claws, a left dragging plate and a right dragging plate, wherein the openings of the two V-shaped claws opposite and the left dragging plate and the right dragging plate form a pair of jaws capable of opening and closing; the drive mechanism is arranged in the cavity of the supporting seat and comprises a pneumatic motor fixed at one side of the cavity of the supporting seat, a set of gears and pinions installed in the center of the cavity of the supporting seat in a meshed way, a left handed ballscrew pair and a right handed ballscrew pair, wherein the pinions are sleeved with the motor by a shaft, the two ballscrew pairs are inserted into inner bores of the gears by shafts, and ball nuts are respectively and fixedly connected with the left dragging plate and the right dragging plate. The device has functions of excircle automatic positioning andself-adaptively clamping and protecting and can stably follow up the cutting motion of a cutter so that a certain cutting depth is kept between the cutter and the excircle of each section of a workpiece.

Wide light evening light source module

The invention relates to a backlight module with wide amplitude and even light, which can be used as light source by installing in lamp house by assembling one or a plurality of modules. The invention comprises a straight tube type light source, an even light reflection board with multi turning surfaces and an even light bowl. The reflection board with multi turning surfaces and even light respectively comprises a reflection area, a lens diffuse mixing reflection area and a diffuse reflection area from central line to two sides, and each reflection area is formed by one or more than one reflection surfaces, and positioned under the straight tube type light source. The even light bowl is positioned above the straight tube type light source, and provided with a rhomboidal beam orifice, and the edge is in randomly scattered tooth shape, and the face facing the light source is the lens reflecting surface, and the face facing the display surface is the diffuse reflection surface. The design of three areas solves the difficulty of reflected light distribution and control. Reflection ray can be reflected in a cross way in the distance by the even light bowl, and the light ray can be gentler. The effective use rate of the module reaches about 90 percent, wide amplitude reaches 500 to 600 mm, and lighting evenness reaches more than 90 percent. Moreover, the advertising light box thickness is controlled between 70 mm to 50 mm.
