This invention discloses a semiconductor quartz component polishing device, relating to the field of quartz component polishing technology. The device includes a main body, inside which a polishing assembly and a rotating assembly coaxially arranged with the polishing assembly are installed. A mounting arm is mounted on the rotating end of the rotating assembly, and a ball head seat is mounted at the bottom of the mounting arm. A positioning assembly capable of vertical rotation is installed inside the ball head seat. Through the arrangement of the polishing assembly and the positioning assembly, the quartz rod is positioned, allowing the polishing assembly to first polish the end of the quartz rod. Then, combined with the cooperation of the rotating assembly and the electric push rod, the entire circumference of the quartz rod's end face can be uniformly and continuously contacted with the polishing assembly. This eliminates the need for manual polishing of the quartz rod by hand, efficiently chamfering the end of the quartz rod, eliminating quality fluctuations caused by inconsistent polishing force and path during manual polishing, effectively removing micro-cracks, scratches, and unevenness left from cutting, and reducing potential stress concentration points.

This utility model belongs to the technical field of rebar processing equipment, specifically relating to a straightening and traction fixing device for coiled rebar. The lower end of a support column is mounted on one end of the base along its length via a rotating mechanism. A support beam is provided in the upper middle part of the support column, extending upwards and inclined towards the other end of the base. The rotating mechanism includes a rotating seat and a rotating body, with the rotating body rotatably connected within the rotating seat. The upper end of the rotating body is fixed to the support column. Limiting grooves are provided on both sides of the rotating seat corresponding to the width of the base, and limiting strips extending into the limiting grooves are provided on both sides of the rotating body. With this rotating mechanism featuring a limiting structure, the support column can rotate horizontally relative to the rotating seat via the rotating body. Combined with the angle limitation of the fan-shaped limiting grooves, this not only adaptively compensates for the angular deviation of the coiled rebar unwinding, eliminating torsional stress in the rebar, but also prevents excessive deflection of the support column, avoiding feeding jams and equipment shaking, significantly improving the straightening accuracy of the rebar.

The utility model discloses a flange type low-temperature valve supporting structure which comprises a valve body supporting assembly and a heat insulation assembly which are connected through a connecting assembly to achieve a supporting function. The valve body supporting assembly comprises a hoop and a supporting frame, the heat insulation assembly comprises a hard heat insulation block and a bottom plate, and the hard heat insulation block can bear the weight of a valve, block heat conduction between the valve body supporting structure and an external supporting body and block a cold bridge. According to the supporting structure, the phenomenon that the deflection of the valve is too large due to the fact that the valve body is too heavy is avoided, cold energy of a medium is prevented from being transmitted to an external supporting body through the supporting piece, and a cold bridge is effectively avoided; the utility model has the characteristics of reasonable structural design, stable and reliable performance, wide application scene and the like.
