Abstract
A kind of sphere grinder.It is characterized in that: described frame is provided with rotary table; Described rotary table is provided with and can clamps spheroid and the clamping rotating mechanism driving spheroid to rotate; Described frame is also provided with the grinding mechanism for grinding spheroid, described grinding mechanism comprises driving shaft, connecting axle for connecting valve seat, and the axis centre of described driving shaft and connecting axle not on the same axis, and is connected by a connector.Its advantage is simple and reasonable, and can be able to grind whole sphere, improves grinding precision, spheroid all can be closely cooperated with valve seat under any state, improves ball valve overall tightness.
Description
Technical field
The utility model relates to a kind of valve process equipment, is specifically related to a kind of sphere grinder.
Background technology
Ball valve is that opening and closing element is spheroid, is driven by valve rod, and around the valve that the axis of valve rod rotates.Ball valve in many pipelines, for controlling the pressure of fluid, flow and the flow direction.Concerning most of valve, sealing problem is matter of utmost importance, and the sealing property of ball valve requires very high, thus also very high to the requirement of sphere.The sphere of usual employing valve seat and spheroid carries out match grinding, makes to reach ball seal face and coordinating between valve seat best cooperation.
Usually, ball valve adopts hand lapping or mechanical lapping usually to the grinding of spheroid, but hand lapping inefficiency, labour intensity is large, and general of existing mechanical lapping carries out match grinding to ball seal end and valve seat, cannot realize comprehensive grinding of sphere, cause spherome surface uneven, thus when ball valve unlatching or closedown, easily wear and tear valve seat, affects ball valve sealing performance.
Utility model content
In order to overcome the deficiency of background technology, the utility model provides a kind of sphere grinder, solves existing grinder and only grinds ball seal end and valve seat, cause the problem of spherome surface injustice.
The technical scheme that the utility model adopts: a kind of sphere grinder, comprises frame, and described frame is provided with rotary table; Described rotary table is provided with and can clamps spheroid and the clamping rotating mechanism driving spheroid to rotate; Described frame is also provided with the grinding mechanism for grinding spheroid, described grinding mechanism comprises driving shaft, connecting axle for connecting valve seat, and the axis centre of described driving shaft and connecting axle not on the same axis, and is connected by a connector.
The first motor that described rotary table comprises rotating disc, drives rotating disc to rotate.
Described clamping rotating mechanism comprises the support be fixedly installed on the rotating pan and the thimble be arranged on support, rotating shaft and installation fixture on the rotary shaft, described thimble withstands the two ends of rotating shaft, and one of them thimble is connected with the second motor, described fixture and spheroid vias inner walls secure fit.
Also gear reduction is provided with between described thimble and the second motor.
Described connector is in " L " character form structure.
The beneficial effects of the utility model are: adopt above scheme, simple and reasonable, and can be able to grind whole sphere, improve grinding precision, spheroid all can be closely cooperated with valve seat under any state, improve ball valve overall tightness.
Accompanying drawing explanation
Fig. 1 is the utility model example structure schematic diagram.
1-frame in figure, 2-rotating disc, 3-first motor, 4-support, 5-thimble, 6-rotating shaft, 7-fixture, 8-second motor, 9-reduction gearing, 10-valve seat, 11-connecting axle, 12-connector, 13-driving shaft, 14-the 3rd motor, 15-spheroid.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model embodiment is described further:
As shown in the figure, a kind of sphere grinder, comprises frame 1, and described frame 1 is provided with rotating disc 2, and described rotating disc 2 is driven by the first motor 3 of bottom and rotates, and rotating disc 2 rotates and spheroid 15 can be driven around vertical axis fast rotational.
Described rotating disc 2 is provided with and can clamps spheroid 15 and the clamping rotating mechanism driving spheroid 15 to rotate, the fixture 7 that described clamping rotating mechanism comprises the support 4 be fixedly installed on rotating disc 2 and the thimble 5 be arranged on support 4, rotating shaft 6 and is arranged on rotating shaft 6, described thimble 5 withstands the two ends of rotating shaft 6, one of them thimble 5 is connected with the second motor 8, described fixture 7 and spheroid 15 vias inner walls secure fit, spheroid 15 is located by thimble 5 and is driven rotation, coordinate with rotating disc 2 and rotate, sphere forms a Continuous maching surface.
Also be provided with gear reduction 9, the rotating speed of the thimble 5 that slows down between described thimble 5 and the second motor 8, ball lapping precision can be controlled further.
Described frame 1 is also provided with the grinding mechanism for grinding spheroid, described grinding mechanism comprises driving shaft 13, for the connecting axle 11 of connecting valve seat 10, the axis centre of described driving shaft 13 and connecting axle 11 is not on the same axis, and be connected by the connector 12 of " L " font, described driving shaft 13 is driven by the 3rd motor 3 and rotates, thus drive valve seat 10 to swing back and forth around driving shaft 13 rotation, thus make the grinding expanded range of valve seat 10 and spheroid sphere to whole sphere, thus raising grinding precision, spheroid all can be closely cooperated with valve seat under any state, improve ball valve overall tightness.
