The utility model discloses a bearing housing processing clamp, which belongs to the technical field of bearing housing processing and comprises a lathe faceplate and a positioning plate, and a positioning boss is arranged in the middle of the positioning plate. The positioning boss and the lathe faceplate are coaxial; and at least two pressing rods are detachably mounted on the lathe faceplate. A positioning boss in the center of the positioning disc is positioned and inserted into a machined first bearing hole, the edge of a flange is pressed through two pressing rods, the end face of the flange is tightly attached to the positioning disc, the positioning disc is driven to rotate through a lathe faceplate, and therefore the bearing box is driven to rotate; the end face away from the flange and the second bearing hole are machined through the lathe, the high coaxiality of the first bearing hole and the second bearing hole is effectively guaranteed, and the perpendicularity of the end face and the bearing hole is guaranteed. And the secondary clamping of the bearing box body is simple, convenient and reliable, tedious alignment is not needed, the time is greatly saved, the working efficiency is improved, and the production cost is reduced. The overall structure is simple, using is convenient, and practicability is good.

The utility model relates to a numerical control lathe thin-wall part machining universal tool which comprises a tool body of a multi-layer structure, the lowermost layer of the tool body is connected with a lathe faceplate, grooves with various specifications and diameters are formed in the front face of the tool body of the lowermost layer and used for being matched with and assembling profiling of different specifications, and therefore machining adaptation of different thin-wall part products is achieved. Through an innovative multi-layer structure and replaceable profiling design, the manufacturing cost of the profiling tool is reduced, the clamping efficiency of debugging is improved, rapid, efficient and low-cost machining of thin-walled workpiece products in numerical control lathe machining is achieved, and remarkable beneficial effects are achieved.

The invention relates to a large thin-wall workpiece turning vibration reduction tool which comprises a fixed vibration reduction mechanism and a fixed vibration reduction mechanism, the fixed vibration reduction mechanism comprises a plurality of vibration reduction rings, the inner sides of the vibration reduction rings are connected with vibration reduction structures, the vibration reduction rings are arranged outside a machined workpiece in a surrounding mode and connected with a lathe faceplate, and the vibration reduction structures provide damping force for workpiece vibration; the movable vibration reduction mechanism comprises a connecting base, a vibration reduction plate and a vibration reduction assembly, the vibration reduction plate can move relative to the connecting base in the first direction, the vibration reduction assembly comprises a displacement amplification structure and a damper, the displacement amplification structure is connected with the vibration reduction plate and the damper, and the displacement of the vibration reduction plate is amplified and input into the damper; the vibration reduction plate is attached to the outer wall or the inner wall of the turning position of the machined workpiece, the first direction is parallel to a first straight line which passes through a cutting point and perpendicularly intersects with the axis of the machined workpiece, and the connecting base is fixed relative to the machined workpiece in the first direction. Vibration in the workpiece machining process can be reduced, machining can be conducted under high machining technological parameters, and high quality and high efficiency of workpiece machining are guaranteed.

This utility model relates to the field of machining technology, and in particular to a crankshaft lathe faceplate with a support and locking device. The faceplate body is equipped with a support device, and a ring is provided around the circumference of the faceplate body. At least one locking device is provided around the faceplate body, comprising two opposing clamping members for locking the ring. Each clamping member is equipped with a pin as a fulcrum and can swing around it. Each clamping member has a piston at its tail as a drive for its swing. The pistons of the two clamping members are arranged oppositely, with opposite pushing directions. In this embodiment of the utility model, a ring is provided at the edge of the faceplate body, and a locking device is provided around the faceplate body, comprising two clamping members that can lock the ring. Each clamping member is equipped with a piston, and the piston's pushing action can quickly lock the ring, thereby locking the faceplate. This prevents changes in the angle of force on the workpiece during crankshaft journal machining, thus ensuring crankshaft machining accuracy.
