The utility model discloses a compressor valve piece polishing device, including base, the upper end right side fixed mounting of base has the vertical board, the right -hand end fixed mounting of vertical board has first electric jar, the output of first electric jar swing joint has grinding wheel, the upper end left side fixed mounting of base has L shape frame, the right -hand end downside fixed mounting of L shape frame has fixed plate, the upper end of fixed plate is swing joint with carousel through the pivot, aims at solving the problem of polishing uneven. Its technical scheme main point is: a compressor valve piece polishing device. The utility model utilizes the arc -shaped groove structure that has on valve piece, is realized to valve piece circumferential position angle's accurate locking through adjustable arc -shaped positioning insert block and cooperation, and the positioning column of cooperation center carries out radial positioning, and the common action of both, has guaranteed that the position of valve piece is completely consistent each time clamping, has solved the problem of partial over -grinding or under -grinding because of the jumping thoroughly, has improved the uniformity of polishing significantly.

The application discloses a high-shading PETG shrink film and a preparation system thereof, and relates to the technical field of plastic film production. The preparation system comprises a feeding cylinder, a first conveying screw rod rotatably installed in the feeding cylinder, a driving element connected with the first conveying screw rod and installed at one end of the feeding cylinder, an extrusion die head installed at the other end of the feeding cylinder, a second conveying screw rod installed in the feeding cylinder, a supporting and mixing mechanism installed between the first conveying screw rod and the second conveying screw rod, and a reciprocating filtering assembly movably installed between the supporting and mixing mechanism and the second conveying screw rod. The application limits the shading agent to be rutile titanium dioxide with a specific particle size range and the adding proportion, so that the shrinkage performance of the film is considered while the high-shading property is ensured. The supporting and mixing mechanism driven by the first conveying screw rod is arranged in the preparation system, so that the forced mixing and stirring of the material are realized in the conveying process.

The invention relates to the technical field of all-in-one machines, and discloses a steel bar sawing and threading all-in-one machine which comprises a mounting frame, an annular guide rail is arranged at the top end of the mounting frame, a plurality of sets of normally-closed clamp mechanisms are arranged at the top end of the annular guide rail, and each normally-closed clamp mechanism comprises an upper clamp cover, a lower clamp body, a connecting roller, a torsion spring and a conveying sliding table. The upper clamp cover is arranged at the top end of the lower clamp body, the lower clamp body is arranged at the top end of the conveying sliding table, the connecting rolling wheel is arranged on one side of the upper clamp cover, the linear guide rail is arranged at the top end of the mounting frame, and the follow-up redundancy supporting mechanism is arranged at the top end of the linear guide rail. Steel bar deflection and tailing waste are eliminated through multi-point relay clamping; the follow-up support provides rigid constraint at a sawing point to ensure that a notch is vertical; accurate positioning of the reinforcing steel bars from conveying to machining is achieved through redundancy constraint and undisturbed handover, secondary errors are thoroughly eliminated, and mantle thread chatter marks are completely eradicated; closed-loop circulation conveying works in parallel, and the machining efficiency is greatly improved.

The utility model discloses an automatic polishing device of automobile crankshaft, including work table, the rear side of work table is rotatoryly installed with first drive screw rod, is screw -threaded to be installed with mobile seat on first drive screw rod, is rotatoryly installed with polishing machine on mobile seat, the polishing machine is connected with first telescopic cylinder, the front side of work table is rotatoryly installed with second drive screw rod, is screw -threaded to be installed with mounting bracket on second drive screw rod, is rotatoryly installed with adjusting box on mounting bracket, the adjusting box is connected with second telescopic cylinder, is rotatoryly installed with adjusting screw rod in adjusting box, is screw -threaded to be installed with adjusting seat on adjusting screw rod, the adjusting seat is connected with connecting frame, the connecting frame is connected with auxiliary support, is rotatoryly installed with auxiliary pressure wheel on auxiliary support, the utility model discloses set up auxiliary pressure wheel on the other side of polishing machine, and auxiliary pressure wheel carries out dynamic abutment to the polishing position to eliminate the deflection and vibration of crankshaft because of unilateral stress.

This utility model relates to a positioning device for precision machining of metal castings. It includes a base plate, a support platform for supporting the metal casting, positioning elements for positioning the metal casting, a swing rod for moving the positioning elements, a turntable for swinging the swing rod, a rotating rod for rotating the turntable, and a transmission device mounted on the base plate. The support platform is mounted on the top of the base plate; both ends of the support platform have sliding openings; two sets of symmetrically arranged positioning elements are simultaneously slidably connected to the two sets of sliding openings; the turntable is arranged around the rotating rod. This invention solves the technical problem that existing positioning devices struggle to quickly adapt to the machining needs of castings of different models and sizes while ensuring machining accuracy. Furthermore, the positioning plates of existing devices often use welded or integral structures, requiring the disassembly of numerous related components when replacing the positioning plate to accommodate castings of different shapes, making maintenance and replacement extremely difficult.
