6 results about "Roller burnishing" patented technology

This invention relates to the field of machining tool technology, and more particularly to a mirror-finish roller burnishing cutter head. The cutter head includes a cutter head body with multiple mounting positions for mounting roller burnishing heads. Each mounting position is equipped with an adjustment mechanism, which independently adjusts the axial extension of the roller burnishing head relative to the end face of the cutter head body. This invention improves machining efficiency by providing multiple roller burnishing heads on the cutter head body and independently adjusting their axial extension. Adjusting the axial extension of each roller burnishing head through the adjustment mechanism ensures that the working end faces of each head are coplanar, eliminating end tooth runout and guaranteeing uniform pressure. Furthermore, when a roller burnishing head wears out, it can be individually compensated or replaced, extending tool life. This effectively solves the technical problems of low planar efficiency in single-head roller burnishing cutters and large end tooth runout in multi-head roller burnishing cutters, leading to uneven pressure and poor flatness.

This product is a roller burnishing tool that is attached to the tool post of a lathe and performs mirror finishing on spherical surfaces.

The utility model discloses a dry type roller polishing device. The dry type roller polishing device comprises a main body support, a polishing roller and a cover. A locking groove is formed in the cover, a rotating groove communicated with the locking groove is formed in the polishing roller, a rotating shaft is fixedly arranged in the rotating groove, a rotating block is rotationally installed on the rotating shaft, a locking block is fixedly arranged on the circumferential wall of the rotating block, and the locking block can be driven to rotate through a locking piece so that the locking block can be inserted into the locking groove; through the arrangement of the rotating block, the locking block, the locking groove and the locking piece, an operator can lock or unlock the cover only by rotating the knob, the operation time consumption is reduced through the design, and the working efficiency is remarkably improved; through the arrangement of the connecting shaft, the gear assembly and the power assembly, synchronous rotation of the polishing roller and the polishing roller can be achieved only through one driving motor, the purpose that a workpiece in the polishing roller rolls evenly is achieved, and energy consumption is low.

The invention belongs to the technical field of accessory stamping machining, and particularly relates to an accessory production die stamping device which comprises an upper die and a lower die. A punch and a plurality of pre-pressing springs for positioning a stamping part are arranged in the upper die; a groove is formed in the top end of the lower die, a base is arranged in the groove, and a base is rotationally connected into the groove; a material pushing assembly is arranged on the base; an air pressure conduction assembly and a hole processing assembly are arranged on the base; when a punch is used for punching, a material pushing assembly is synchronously extruded, a pressure roller is driven to trigger an air pressure conduction assembly to distribute air to a hole processing assembly through an air channel, a sliding block is driven to drive a scraper to rotate with a base as the axis to cut burrs, punching and burr cleaning integrated machining is achieved, and traditional modes such as manual grinding and roller polishing do not need to be relied on; the labor intensity is reduced, the problems of uneven hole wall roughness, workpiece deformation and high device maintenance cost are solved, batch production is adapted, and the machining efficiency and consistency are improved.

This invention belongs to the field of wind turbine bearing manufacturing, specifically relating to a process method for the friction surface of a yaw gear ring. The process method includes: semi-finish turning: using a semi-finish turning tool to semi-finish turn the friction surface of the yaw gear ring, removing most of the excess material; finish turning: using a finish turning tool to finish turn the friction surface of the yaw gear ring, forming evenly spaced oil reservoirs on the friction surface surface; and roller burnishing: using a dedicated roller burnishing tool to roller burnish the friction surface of the yaw gear ring, controlling the feed rate and workpiece speed via the machine tool to form a stable stress layer on the friction surface surface, while ensuring the surface roughness and profile length support ratio. This invention proposes a process method for the friction surface of a yaw gear ring. Using the above processing method ensures the stability of the yaw gear ring friction surface quality during mass production, guarantees the load-bearing capacity of the yaw gear ring, avoids abnormal vibration and noise during the operation of the yaw system, and improves the service life of the yaw gear ring.
