Abstract
The invention discloses a valve plate grinding equipment comprising a workbench. A stand column is arranged on the workbench, a grinding wheel is arranged on the stand column and is mounted on the side face of the stand column through a rotating shaft, an air cylinder and a clamping component are arranged on the workbench, a valve is clamped by a push rod of the air cylinder and the clamping component so as to be positioned below the grinding wheel, the clamping component comprises three clamping wheels in 'triangular' arrangement, an annular flange with the right trapezoid cross section is arranged on the peripheral face of the grinding wheel, and the grinding face of the annular flange consists of an arc face and a tapered face which are connected into a whole through a transition face. The valve plate grinding equipment has the advantages that the grinding wheel is designed with multi-shape faces, the outer circumference, the tapered face, the transition outer circumference and an outer circumference chamfer of a valve plate can be formed by grinding once, and thereby the technological process is shortened, repetitive positioning is reduced and processing precision of the valve is improved; labor employment cost is reduced and production efficiency is improved substantially.
Description
Technical field
The present invention relates to a kind of grinding attachment, particularly a kind of grinding attachment of grinding Valve Disc, belongs to the technical field of valve process equipment.
Background technology
Along with internal combustion engine is to the development in adjustment high load capacity direction, the more and more main height of required precision of valve.Traditional valve adds man-hour, by the disc portion of valve for coiling cylindrical and chamfering, the dish conical surface, transition arc, three parts are processed respectively by three process, all turnery processing is adopted owing to adding man-hour, and all to carry out clamping due to every procedure, easily produce error due to multiple clamping, therefore, the product valve precision processed and presentation quality poor.
Summary of the invention
Technical problem to be solved by this invention is the equipment for grinding providing a kind of grinding Valve Disc for the deficiencies in the prior art, this equipment for grinding realizes the processing of three process by one-time positioning, decrease the error produced due to multiple clamping, thus, substantially increase the precision of valve.
In order to solve the problems of the technologies described above, the equipment for grinding of a kind of grinding Valve Disc of the present invention, comprise workbench, described workbench is provided with column, described column is provided with emery wheel, described emery wheel is arranged on described column side by rotating shaft, described workbench is provided with cylinder, clamp assembly, valve clamps by push rod and the clamp assembly of described cylinder, valve is made to be positioned at below described emery wheel, described clamp assembly is made up of the pinch wheels that three arrange in triangle disposition, described emery wheel outer peripheral face is provided with annular flange flange, the cross section of described annular flange flange is right-angled trapezium, the grinding face of described annular flange flange is by arcwall face, taper surface forms, described arcwall face and described taper surface are linked into an integrated entity by transition face.
The equipment for grinding of above-mentioned a kind of grinding Valve Disc, wherein, the arc angle α of described arcwall face is 107 degree.Beneficial effect of the present invention: the present invention to the outer unit of the dish of Valve Disc, the dish conical surface, transition cylindrical and the outer first chamfering one-shot forming grinding of dish, can shorten technological process, decrease resetting, thus, improve the machining accuracy of valve.

Below in conjunction with accompanying drawing, the invention will be further described.
As shown in the figure, in order to solve the problems of the technologies described above, the equipment for grinding of a kind of grinding Valve Disc of the present invention, comprise workbench 1, described workbench 1 is provided with column 2, described column 2 is provided with emery wheel 3, described emery wheel 3 is arranged on described column 2 side by rotating shaft, described workbench 1 is provided with cylinder 4, clamp assembly 5, valve 6 clamps by push rod and the clamp assembly 5 of described cylinder 4, valve 6 is made to be positioned at below described emery wheel 3, described clamp assembly 5 is made up of the pinch wheels 51 that three arrange in triangle disposition, described emery wheel 3 outer peripheral face is provided with annular flange flange 31, the grinding face of described flange 31 is by arcwall face 311, taper surface 312 forms, described arcwall face 311 is linked into an integrated entity by transition face 313 with described taper surface 312, the arc angle α of described arcwall face is 107 degree.Described flange 31 is eccentrically set on the outer peripheral face of described emery wheel 3, because described flange is eccentrically set on the outer peripheral face of described emery wheel, improves the intensity of emery wheel, can extend service life of the present invention.The present invention to the outer unit of the dish of Valve Disc, the dish conical surface, transition cylindrical and the outer first chamfering one-shot forming grinding of dish, can shorten technological process, decreases resetting by emery wheel being designed to many types of, thus, improve the machining accuracy of valve; And reduce labor cost, significantly improve production efficiency.
The outer unit of dish of my company and the sharp joint development of Suzhou speciality, the dish conical surface, transition arc and dish portion chamfering form grinding equipment, the three process that disposable processing is original, adopt same positioning datum, decrease multiple clamping error and clamping time, the Product Precision of processing is higher, outward appearance exquisiteness is attractive in appearance, design and installation automatic loading/unloading on equipment simultaneously, a people can operate 3 equipment, reduces recruitment cost to a great extent, break away from the predicament that labour is in short supply, improve economic benefit.
This equipment adopts Taiwan import main shaft, and guarantee machine spindle precision and the failure rate is low that runs up, abrasive material adopts CBN forming grinding wheel, repeatedly can repair plating.Surface design is many types of, substantially increases the service efficiency of grinding tool, and after one-shot forming, every sheet emery wheel can grinding work piece 25-30 ten thousand, considerably reduces auxiliary material consumption.
