6results about How to "Size match" patented technology

The utility model relates to steel ingot casting technical field especially no step heat preservation cap mouth structure, it includes mud cap mouth, iron cap mouth and heat preservation cover. Mud cap mouth is conical, and the inner chamber adopts octagonal plum blossom shape taper structure, and the taper range is 0.8% 1.5%, iron cap mouth includes circular ring and lug, and is installed in close cooperation with mud cap mouth, heat preservation cover is composed of stone wool heat preservation board and metal sheet, and covers in the periphery to reduce the cooling rate. The utility model discloses through optimizing the inner chamber shape and cancelling step structure, reduces stress concentration and slag inclusion defect, significantly improves the billet yield, is applicable to electric furnace ingot and other metal ingot casting process.

This utility model relates to the field of cartoning machine technology, and more particularly to a medicine box positioning and error prevention device for a cartoning machine. The medicine box positioning and error prevention device for a cartoning machine includes a support frame, a control panel, a warning light, a connecting frame, and a vision sensor. Each of the two support frames has symmetrically distributed mounting holes on one side. The control panel is fixedly connected to the left side of one support frame, and a warning light is fixedly connected to the top of the control panel. A connecting frame is fixedly connected between the tops of the two support frames, and a vision sensor is fixedly connected through the middle of the connecting frame. The vision sensor is electrically connected to the control panel. This utility model uses a vision sensor combined with an image recognition algorithm to accurately determine whether a medicine box exists, whether its orientation is correct, and whether it is damaged, tilted, or overlapped. A laser scanner non-contactly detects the height, width, and position of the medicine box to ensure size matching.

The utility model discloses size detection device, including base, base top one side fixedly connected with stand, install lifting mechanism on the stand, be equipped with continuous detection mechanism on the base, continuous detection mechanism includes crossbeam and guide rail, the inside fixedly connected with guide rod of crossbeam, the sliding connection of guide rod has guide block, the fixed mounting of installation board has at guide block bottom -end, the fixed mounting of laser detection head has at installation board bottom -end, one end fixedly connected with electric push rod of guide block, belong to laser detection technical field. This size detection device, through placing work piece on a vacuum chuck, vacuum chuck adsorbs and holds the work piece to be measured, and moves motor drives two vacuum chucks to be at guide rail both ends respectively, one is at detection station, and the other is at the loading and unloading station, utilizes the detection time to replace work piece, reduces the time that work piece occupies to change, thereby can effectively improve the detection efficiency.

The extreme ultraviolet light source collecting mirror of the present invention is used to collect extreme ultraviolet light from an extreme ultraviolet light source in a photolithography process, and includes: a collecting mirror body that collects extreme ultraviolet light emitted from an extreme ultraviolet light source using a collecting mirror reflecting surface having a hole for a light path to pass through, and focuses the collected extreme ultraviolet light to a prescribed region; a collecting mirror transition section to which the collecting mirror body is mounted by means of a shaft-hole fit, and which is integrated with the collecting mirror body; and a mounting bracket to which the collecting mirror transition section is mounted by means of a shaft-hole fit.

The invention relates to the technical field of automatic ball mounting of ball bearings, and discloses an automatic ball mounting device for ball bearing production. A ball guide-in assembly is fixedly arranged on a supporting assembly, a mechanical arm is fixed to the outer edge of the top of the supporting assembly, and four first positioning assemblies are evenly distributed on the inner side of the supporting assembly; a second positioning assembly is fixed to the middle of the top of the supporting assembly, the outer diameter D of the outer ring can be visually obtained through the compression amount of a supporting spring, centering operation of the inner ring and the outer ring is completed through resilience force of the second positioning assembly, and then the outer ring and the inner ring can be centered with a positioning column. And meanwhile, the diameter d of the inner ring is detected through the compression amount of the first pressurizing spring and the second pressurizing spring, the size and the assembling number of the ball bodies can be conveniently matched according to the difference value of the outer diameter D of the outer ring and the inner diameter d of the inner ring, then the ball guiding-in assembly acts to complete the discharging operation of the corresponding ball bodies, and the ball loading accuracy and the matching degree are improved.
