Abstract
A kind of sphere grinder.It is characterized in that: described frame is provided with rotary table；Described rotary table is provided with the clamping rotating mechanism that can clamp spheroid and drive spheroid to rotate；Being additionally provided with the grinding mechanism for grinding spheroid in described frame, described grinding mechanism includes drive shaft, connecting shaft for connecting valve seat, and the axis centre of described drive shaft and connecting shaft the most on the same axis, and is connected by a connector.Have an advantage in that simple and reasonable, and whole sphere can be able to be ground, improve grinding precision, make spheroid all can closely cooperate with valve seat under any state, improve ball valve overall tightness.
Description
Technical field
The present invention relates to a kind of valve process equipment, be 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 the valve rotated around the axis of valve rod.Ball valve is in many pipelines, for controlling the pressure of fluid, flow and the flow direction.For most of valves, sealing problem is matter of utmost importance, and the sealing property of ball valve requires the highest, thus the requirement to sphere is the highest.Generally use the sphere of valve seat and spheroid to carry out match grinding, make to reach coordinating between ball seal face and valve seat optimal cooperation.
Generally, ball valve generally uses hand lapping or mechanical lapping to the grinding of spheroid, but hand lapping inefficiency, labor intensity is big, and general of existing mechanical lapping carries out match grinding to ball seal end and valve seat, it is impossible to realize comprehensive grinding of sphere, cause spherome surface uneven, thus ball valve is when being turned on and off, easily wear and tear valve seat, affects ball valve sealing performance.
Summary of the invention
In order to overcome the deficiency of background technology, the present invention provides a kind of sphere grinder, solves existing grinder and is only ground ball seal end with valve seat, causes the problem that spherome surface is uneven.
The technical solution adopted in the present invention: a kind of sphere grinder, including frame, described frame is provided with rotary table；Described rotary table is provided with the clamping rotating mechanism that can clamp spheroid and drive spheroid to rotate；Being additionally provided with the grinding mechanism for grinding spheroid in described frame, described grinding mechanism includes drive shaft, connecting shaft for connecting valve seat, and the axis centre of described drive shaft and connecting shaft the most on the same axis, and is connected by a connector.
Described rotary table includes rotating disk, the first motor driving rotating disk to rotate.
Described clamping rotating mechanism includes the support being fixedly installed on the rotating pan and the thimble being arranged on support, rotary shaft and installs fixture on the rotary shaft, described thimble withstands the two ends of rotary shaft, and the connection of one of them thimble has the second motor, described fixture and spheroid vias inner walls secure fit.
It is additionally provided with gear reduction between described thimble and the second motor.
Described connector is in " L " character form structure.
The invention has the beneficial effects as follows: use above scheme, simple and reasonable, and whole sphere can be able to be ground, improve grinding precision, make spheroid all can closely cooperate with valve seat under any state, improve ball valve overall tightness.
Accompanying drawing explanation
Fig. 1 is embodiment of the present invention structural representation.
1-frame in figure, 2-rotating disk, 3-the first motor, 4-support, 5-thimble, 6-rotary shaft, 7-fixture, 8-the second motor, 9-reduction gearing, 10-valve seat, 11-connecting shaft, 12-connector, 13-drive shaft, 14-the 3rd motor, 15-spheroid.
Detailed description of the invention
Embodiments of the present invention is further illustrated below in conjunction with the accompanying drawings:
As it can be seen, a kind of sphere grinder, including frame 1, described frame 1 is provided with rotating disk 2, and described rotating disk 2 is driven by the first motor 3 of bottom and rotates, and rotating disk 2 rotates and spheroid 15 can be driven quickly to rotate around vertical axis.
Described rotating disk 2 is provided with the clamping rotating mechanism that can clamp spheroid 15 and drive spheroid 15 to rotate, described clamping rotating mechanism includes the support 4 being fixedly installed in rotating disk 2 and the thimble 5 being arranged on support 4, rotary shaft 6 and the fixture 7 being arranged in rotary shaft 6, described thimble 5 withstands the two ends of rotary shaft 6, one of them thimble 5 connects the second motor 8, described fixture 7 and spheroid 15 vias inner walls secure fit, spheroid 15 is positioned by thimble 5 and is driven rotation, coordinate rotation with rotating disk 2, sphere is formed a Continuous maching surface.
It is additionally provided with gear reduction 9 between described thimble 5 and the second motor 8, the rotating speed of the thimble 5 that slows down, ball lapping precision can be controlled further.
The grinding mechanism for grinding spheroid it is additionally provided with in described frame 1, described grinding mechanism includes drive shaft 13, connecting shaft 11 for connecting valve seat 10, the axis centre of described drive shaft 13 and connecting shaft 11 is the most on the same axis, and be connected by the connector 12 of " L " font, described drive shaft 13 is driven by the 3rd motor 3 and rotates, thus drive valve seat 10 to rotate around drive shaft 13 and swing back and forth, so that the grinding expanded range of valve seat 10 and spheroid sphere is to whole sphere, thus improve grinding precision, make spheroid all can closely cooperate with valve seat under any state, improve ball valve overall tightness.
