Vertical lathe for profiling internal and external circle of piston ring

Abstract

The invention relates to an upright piston ring round lathe, wherein its main axle frame is integral; four parts at two shoulders of main axle frame have four roller straight guide tracks; four tracks are fixed at four grooves at two shoulders; eight blocks are fixed at the inner sides of left and right posts; the blocks have enough mounting holes to be mounted on the left and right posts; each two blocks have one damping block between them to reduce the cutting vibration. The invention has compact structure, high accuracy, high producing efficiency and low cost.

Description

Technical field [0001] The invention relates to an improvement of a vertical lathe, which is mainly used for forming the inner and outer circles of piston rings. technical background [0002] The vertical piston ring inner and outer circle profiling lathe is an important equipment for piston ring forming. It is more advanced than the single outer circle profiling lathe and the horizontal inner and outer circle profiling lathe. High efficiency and other advantages, but its cost is expensive, so people continue to propose improved solutions to related technologies, for example, Chinese patent CN200410046700.0 discloses a kind of bed base There is a door-type box column on the top, and its door frame is equipped with an integral frame-type carriage head that slides up and down along it with a servo lifting drive, and an upper spindle and a lower spindle that are synchronously driven by the main motion servo motor are arranged on the vertical coaxial axis of the head. , the fro...

[0002] The vertical piston ring inner and outer circle profiling lathe is an important equipment for piston ring forming. It is more advanced than the single outer circle profiling lathe and the horizontal inner and outer circle profiling lathe. High efficiency and other advantages, but its cost is expensive, so people continue to propose improved solutions to related technologies, for example, Chinese patent CN200410046700.0 discloses a kind of bed base There is a door-type box column on the top, and its door frame is equipped with an integral frame-type carriage head that slides up and down along it with a servo lifting drive, and an upper spindle and a lower spindle that are synchronously driven by the main motion servo motor are arranged on the vertical coaxial axis of the head. , the front of the car is also equipped with a main shaft axial pressing device, the lower main shaft is hollow, the bottom plate of the servo tool holder is installed on the column of the door-type box, and a skateboard driven by profiling servo to slide horizontally is installed on the bottom plate. The outer turning tool on the same radial plane of the main shaft is coaxial with the lower main shaft, the copying servo motor, the main motion servo motor, and the servo motor of the servo lifter are connected with the numerical control system. The shape line data is placed in the computer, and the movement of the turning tool is realized through a fast servo mechanism, but this mechanism is relatively loose, occupies a large area, and the production cost of the whole machine is high
