Abstract
The invention relates to a spherical surface finishing machine, belonging to the field of grinding machines. The spherical surface finishing machine is provided with a worktable. The spherical surface finishing machine is characterized in that a spindle driving mechanism is mounted at one end of the worktable, is powered by a spindle motor and is connected a spindle; a supporting spindle is mounted at the other end of the worktable through a supporting mechanism and is located at the same axis with the spindle, the supporting mechanism is mounted on a linear guiding wheel and is connected with a movable oil cylinder stretching rod arranged at the lower part of the worktable, and the movable oil cylinder is powered by a hydraulic power unit; a cutter table mechanism is mounted at the middle of the worktable and is driven by a swinging motor arranged at the lower part of the worktable, and a cutter is mounted at the upper end of the cutter table mechanism. The spherical surface finishing machine has the beneficial effects that the machining precision is high, and the roundness and surface roughness of a sphere are guaranteed; the efficiency is high; the operation is safe, and an operator only needs to feed and detach the sphere in the whole machining process and does not contact with the sphere in a cutting process; the environment is protected, no dust is generated in the machining process, and only scrap-shaped waste materials are generated.
Description
Technical field
The present invention relates to grinding machine field, at length say it is a kind of sphere polishing machine, relate in particular to ball body of valve high accuracy sphere polishing machine.
Background technology
As everyone knows, ball body of valve is valve important composition part, and its outer surface directly contacts with sealing ring, so its circularity and outer surface roughness directly affect valve seal.In order to guarantee the quality of valve, must guarantee that ball body of valve has very high circularity and good surface roughness.Present stage, spherome surface fine finishining mainly obtains by artificial polishing.Artificial polishing main working process is: spheroid is with main shaft High Rotation Speed, and artificial hand is taken sand paper to be placed on the spheroid of High Rotation Speed and moved back and forth, and the friction by sand paper and spheroid is with the unnecessary or coarse part in polished ball surface.During artificial polishing, along with people's hand position and sand paper different from sphere-contact dynamics, there is very large randomness in spheroid circularity, surface roughness, and artificial polishing efficiency is low, danger coefficient is high, polishing process produces a large amount of fine dusts, contaminated environment, harm health of human body.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of sphere polishing machine, machining accuracy is high, guarantees spheroid circularity and surface roughness; Efficiency is high; Safety, artificial of whole process needs upper ball, unloads ball, and working angles does not manually contact spheroid; Environmental protection, process does not produce dust, only produces long chip scrap.
The technical solution adopted for the present invention to solve the technical problems is: a kind of sphere polishing machine, be provided with workbench, it is characterized in that, workbench one end is provided with main shaft drives mechanism, main shaft drives mechanism provides power by spindle motor, main shaft drives mechanism is connected with main shaft, the workbench other end is provided with supports main shaft through supporting mechanism, supports main shaft and main shaft are on same axis, supporting mechanism is arranged on straight-line guidance rail, supporting mechanism is connected with the Shift cylinder expansion link that is arranged on workbench bottom, Shift cylinder provides power by hydraulic power unit, workbench middle part is provided with Dao Tai mechanism, Dao Tai mechanism is driven by the oscillating motor that is arranged on workbench bottom, Dao Tai mechanism upper end is provided with cutting knife.
The invention has the beneficial effects as follows, machining accuracy is high, guarantees spheroid circularity and surface roughness; Efficiency is high; Safety, artificial of whole process needs upper ball, unloads ball, and working angles does not manually contact spheroid; Environmental protection, process does not produce dust, only produces long chip scrap.
