Fault diagnosis machining equipment for pin hole driving sphere

Abstract

The invention discloses fault diagnosis machining equipment for a pin hole driving sphere, and relates to the technical field of machining of non-standard spheres. The fault diagnosis machining equipment specifically comprises a base, a composite clamp mechanism, an adjustable rotary turning mechanism, an inner spherical surface machining pin and a fault monitoring mechanism; an operation table isarranged at one side of the bottom end of the base; and an indicating lamp is arranged at the middle end of a dust-proof housing. According to the fault diagnosis machining equipment for the pin holedriving sphere, through the arrangement of the composite clamp mechanism, the outer spherical surface and the inner spherical surface of a non-standard sphere can be independently clamped to ensure that the machining position of a workpiece cannot be shielded in a clamping process; through a movable connection design of a spatial shaft sleeve and a sliding groove which is formed between bearings,the workpiece is clamped by clamping jaws when the inner spherical surface is machined by a machine tool; a spline pin opening mechanism is located inside a chamber below a chuck to prevent the influence on the machining position; when the outer spherical surface is machined by the machine tool, the clamping jaws of the chuck are driven to move downwards by the spatial shaft sleeve; the spline pin opening mechanism is used for clamping the inner spherical surface; a streamline design is adopted; and the higher work efficiency achieved.

[0002] The pin-hole drive ball is mainly used to cut, distribute and change the flow direction of the medium in the pipeline. The pin-hole drive ball is widely used in petroleum refining, long-distance pipeline, chemical municipal, steel and other industries. At present, for the ball Workpiece, end surface polishing device is the most common type of finishing device on the market, but most of the device's workpiece trajectory is relatively simple, and the accuracy of the inner spherical surface (spherical deviation, ball diameter variation and surface roughness) directly affects The technical indicators such as the motion accuracy, noise and life of the pin-hole driven ball will affect the performance of equipment and instruments

[0003] The common problems of the existing non-standard ball processing equipment are: there is a cylindrical hole in the middle of the ball, and the existing groove processing of the ball valve ball needs to lock the ball valve ball, and then use the cutting machine to slot the upper end of the ball valve. When cutting and grooving the existing ball valve balls, the balls of the ball valve are generally locked by the extrusion of the locking plate, and the locking plate cannot lock it according to the structure of the ball valve ball, resulting in poor locking effect, because the locking force of the locking plate is too high The assembly will cause a certain deformation on the outer surface of the ball valve ball, which will affect the sealing performance of the ball valve ball body, and the ball valve ball is a smooth spherical structure, and the ball will rotate at a certain angle during cutting, resulting in poor slotting effect of the ball valve ball , and the existing processing procedures are difficult to monitor the processing process and respond quickly, and it is easy to cause irreversible damage to the life of the machine tool and the accuracy of the workpiece due to abnormal vibration of the machine tool and inaccurate position of the tool.
