The application relates to the field of heating pipe processing, and provides a tube needle stamping equipment for a heating pipe, which is applied to the installation of a tube needle and a terminal pin of the heating pipe, the tube needle penetrating through the terminal pin; the stamping equipment comprises a rack, a placing piece, a stamping piece and an abutting piece; the placing piece is installed on the rack, and a placing groove for placing the heating pipe and the needle tube is arranged on the placing piece; the abutting piece is installed on the rack, the tube needle extends to the abutting piece through the placing groove, and the terminal pin is clamped with the abutting piece; the stamping piece is installed on the rack and located above the abutting piece; the stamping piece drives a stamping end to stamp the terminal pin, and the terminal pin is pressed by the stamping end and the abutting piece on the tube needle. The application has the effect of preventing the terminal pin from separating from the tube needle.

The utility model relates to a crystal fine grinding device which comprises a base station with a grinding working groove, a crystal rotating disc, a rotating disc driving assembly, a grinding disc, a swing arm and a swing arm driving mechanism. Wherein the swing arm comprises a transverse swing arm, a longitudinal swing arm and a vertical limiting frame; the vertical limiting frame comprises a vertical limiting rod, at least three connecting frames distributed in an annular array mode, a limiting wheel rod and a limiting wheel, the vertical limiting rod is connected to the front end of the longitudinal swing arm, and the multiple connecting frames are connected to the lower end of the vertical limiting rod in a radial mode; each vertical limiting rod is connected with a limiting wheel rod extending downwards, the lower end of each limiting wheel rod is rotationally connected with a limiting wheel, and the limiting wheels are attached to the side edge of the grinding disc so as to drive the grinding disc to move. The grinding device has the advantages that the grinding disc can make partial surface contact with a crystal, water replenishing is facilitated, the grinding effect is improved, the grinding disc is limited through the limiting wheel, it is guaranteed that the position of the grinding disc is accurate, and it is also guaranteed that the weight except the grinding disc interferes with grinding.

The present application relates to a positioning device, which comprises a base including a plurality of through holes and a sliding groove, a clamping assembly arranged in the sliding groove and including a first clamping block and a second clamping block, and an adjusting assembly including a first driving rod, a second driving rod and at least one rotating rod, the first driving rod including a first threaded section and a first umbrella-shaped gear, the second driving rod including a second threaded section and a second umbrella-shaped gear, the first clamping block and the second clamping block being arranged on the first threaded section and the second threaded section respectively, and each of the rotating rods including a third umbrella-shaped gear, the third umbrella-shaped gear being engaged with the first umbrella-shaped gear and the second umbrella-shaped gear respectively.

The application relates to a fixing structure, which comprises a fixing part, a movable part, a first elastic member, a button and a second elastic member. The fixing part is configured to be fixed to a frame. The movable part is slidingly connected to the fixing part. The movable part is configured to abut against a processing module in the frame. Two ends of the first elastic member abut against the fixing part and the movable part respectively. The button is slidingly connected to the fixing part. The button is configured to selectively combine with or separate from the movable part. Two ends of the second elastic member abut against the fixing part and the button respectively. The button is configured to be pressed along a first direction, so that the button slides away from the movable part along the first direction. When the button separates from the movable part, the first elastic member elastically restores, so that the movable part moves away from the fixing part along a second direction and abuts against an extension member of the processing module. The extension member is arranged on the periphery of the processing module.
