6results about How to "Guaranteed grinding accuracy" patented technology

The utility model discloses a plate polishing device relates to plate polishing technical field, the utility model discloses a work table still includes: adjusting portion, adjusting portion sets up at the top of work table, configuration portion, configuration portion sets up on work table, adjusting portion includes adjusting assembly, adjusting assembly installs at the top of work table, and lifting assembly, lifting assembly installs at the top of work table. The utility model discloses setting adjusting portion, solved because just with plate random placement on polishing belt, simply rely on the movement of polishing belt to drive the plate forward and complete polishing simultaneously, this operation mode lacks the effective positioning and firm fixation of plate, make plate in the polishing process, when receiving slight external force interference or slight change of self -stress, easy to have position deviation, thereby lead to the overall polishing precision to drop, finally cause the problem of adverse effect to finished product quality.

This utility model discloses an automatic grinding device for a coffee grinder blade, relating to the field of blade grinding technology. The device includes a worktable with a rotating placement disc inside. A rotating mechanism for use with the placement disc is located inside the worktable. A central fixing mechanism is provided on the interior and lower surface of the placement disc. A protective cover is fixedly connected to the upper surface of the worktable, and a first cylinder is fixedly mounted on the upper surface of the protective cover. The output end of the first cylinder passes through the protective cover and is fixedly connected to a mounting bracket. A DC motor is fixedly mounted on one side of the mounting bracket, and the output end of the DC motor passes through one side of the mounting bracket and is fixedly connected to a grinding blade. This application uses a central positioning mechanism to ensure the blade is in a centered position when fixed, effectively improving the stability of the equipment operation. The rotating mechanism facilitates uniform and stable rotation of the blade during grinding, thereby improving the grinding efficiency of the grinding equipment.

The utility model discloses a kind of compressor impeller blade top grinding tool, belong to compressor impeller processing field.The tool, including annular fixed plate and transition shaft;The center of the fixed plate is equipped with the through-hole of installation transition shaft, the outer ring of through-hole is equipped with several notches for sliding of bed chuck jaw, it is equipped with several first locating hole, first mounting hole and second mounting hole on fixed plate, through the cooperation of positioning rod and first locating hole, fixed plate is positioned on bed chuck chuck, through the cooperation of first mounting hole, stud, T-shaped block and nut arranged on bed chuck chuck, fixed plate is fixed on bed chuck chuck;The transition shaft fixes impeller, and transition shaft is fixed on fixed plate.The utility model can be separately ground blade top to single impeller blade top, install the tool on multiple ordinary horizontal lathe, then multiple impellers can be simultaneously ground blade top, greatly shorten product manufacturing cycle, and can guarantee grinding accuracy and surface roughness.

This invention discloses an edge grinding device for piston skirt casting, belonging to the field of piston skirt processing technology. The invention comprises an electric telescopic rod, a movable platform, a T-shaped turntable, a pusher groove, movable balls, rubber ring one, and rubber ring two. The top bar is pulled open by a pin shaft, pushing the clamping top blocks outwards, causing multiple clamping top blocks to tightly adhere to the inner wall of the piston skirt body, completing the automatic centering and clamping fixation of the piston skirt body. After the movable platform drives the piston skirt body to press against the grinding belt, rubber ring one on the outer side of the conical seat and rubber ring two on the outer side of the I-shaped seat are tightly pressed together. Driven by a drive motor, transmission wheels one and two drive the I-shaped seat to rotate. Under the friction of rubber ring one and rubber ring two, the T-shaped turntable drives the piston skirt body to rotate slowly around its own axis, pressing against the grinding belt, thereby achieving comprehensive grinding of the piston skirt body's surface edges.

This invention discloses a concave finned high-efficiency heat-dissipating grinding wheel, comprising a base layer and an abrasive layer. Multiple heat dissipation grooves are evenly spaced on the circumferential arc surface of the abrasive layer, and the inner walls of each groove are semi-circular. Concave fins are symmetrically fixedly connected to the inner walls of each groove near their center. Multiple heat dissipation holes are evenly and continuously formed on both sides of the abrasive layer near their edges, and spiral fins are fixedly connected to the inner walls of each hole. This invention significantly increases the heat dissipation area of ​​the grinding wheel by providing heat dissipation grooves with concave fins on the circumferential arc surface and both sides, thus significantly improving heat dissipation efficiency. It can quickly and effectively dissipate the heat generated during grinding, preventing thermal deformation of the grinding wheel due to excessive temperature, ensuring grinding accuracy and surface quality. Furthermore, the concave fins and heat dissipation grooves are integrally formed, resulting in a simple structure, convenient manufacturing process, and ease of large-scale production and application.

The utility model relates to the technical field of polishing device, especially small -size seamless pipe inner repair grinding equipment. It includes installation table body, one pair of installation groove is opened to the top symmetry of installation table body, every installation groove all is provided with transmission assembly, every transmission assembly all is provided with repair grinding auxiliary assembly, and the polishing plate of removable is provided between two repair grinding auxiliary assemblies. The utility model discloses adjustable fixed block through repair grinding auxiliary assembly, and the small diameter seamless steel pipe of different inner diameter is faced, and only needs to carry out fine adjustment to fixed block position through nut and screw rod, makes it and different pipe diameter steel pipe adaptation, and the polishing plate both ends are inserted into the slot fixed, and then realize the polishing of the inner wall of various pipe diameter steel pipe, greatly promote the versatility of equipment processing, satisfy the diversified production demand.
