Abstract
The invention discloses an eccentric grinding tool of a valve body for grinding metal planes in the field of equipment processing. The eccentric grinding tool of the valve body comprises a grinding disc, a grinding head and a transmission shaft; the grinding head is an annular dull polish sheet, and is adhered to the bottom of the grinding disc through double-sided adhesive tapes; the upper part of the grinding disc is provided with a connecting jack; the transmission shaft is fixed on the grinding disc through the connecting jack. The eccentric grinding tool of the valve body is characterized in that one end of the transmission shaft is provided with a connecting bolt, and the other end of the transmission shaft is fixed on a rotary fixture; the connecting bolt is arranged in an eccentric manner; the grinding disc does eccentric rotation in grinding, and can prevent linear or concentric circular-shaped grinding tracks generated in the grinding, and can cover the grinding tracks last time in the next grinding. The eccentric grinding tool of the valve body, provided by the invention, has the advantages of being high in grinding quality, reliable in sealing, simple and reasonable in equipment and the like.
Description
Technical field
The present invention relates to the grinding tool of equipment manufacture field, particularly a kind of eccentric grinding tool of valve body that is applicable to the abrasive metal plane.
Background technology
Grinding tool is the instrument in order to grinding, grinding and polishing.In machine-building and other metal-processing industries, be widely adopted, existing metal flat grinding tool is by the stationary fixture that is fixed on grinding machine, drive the grinding tool rotation by turning cylinder, grinding tool includes mill, bistrique and power transmission shaft, because power transmission shaft and mill are concentric, can produce linearity or concentric circles grinding track in metal surface in process of lapping, affect grinding efficiency and airtight quality.
Summary of the invention
The object of the invention is to overcome deficiency of the prior art, provide a kind of grinding efficiency high, and grind even, good sealing effect, the grinding tool that the grinding track is the minor spiral line.
The objective of the invention is to be achieved through the following technical solutions:
The eccentric grinding tool of a kind of valve body, comprise mill, bistrique and power transmission shaft, bistrique is the ring-type abrasive segments, be built-up in the mill bottom by double faced adhesive tape, the connection jack is arranged at mill top, power transmission shaft is fixed on mill by connecting jack, it is characterized in that: power transmission shaft one end has connecting bolt, the other end is fixed in rotary clamp, connecting bolt is set for the eccentric, linearity or concentric circles grinding track that the eccentric setting of connecting bolt produces in can avoiding grinding, can cover the vestige of last time when next grinding: technique scheme is done to further restriction, power transmission shaft is fixed with being fixedly connected with by latch of mill, technique scheme is done to further restriction, and bistrique is replaceable bistrique, facilitates the replacing of bistrique.
The present invention compared with prior art has following beneficial effect:
1. Grinding Quality is reliable;
2. the sealing surface sealing after grinding is reliable.
3. equipment advantages of simple.
The accompanying drawing explanation
Fig. 1 is the eccentric grinding tool mill of valve body sectional view;
Fig. 2 is the eccentric grinding tool transmission shaft structure of valve body figure;
Fig. 3 is the eccentric grinding tool power transmission shaft of valve body side view.
In figure: mill 1, connection jack 2, bistrique 3, power transmission shaft 4 and connecting bolt 5.
The specific embodiment
Below in conjunction with Figure of description, content of the present invention is described further:
As shown be the eccentric grinding tool structural representation of valve body, comprise mill 1, connect jack 2, bistrique 3, power transmission shaft 4 and connecting bolt 5, the eccentric grinding machine grinding tool of valve body fixes by power transmission shaft 4 and the transmission fixture of drilling machine, the other end of power transmission shaft 4 connects mill 1, traditional power transmission shaft 4 is connected with the concentric shafts that is connected to of mill, mill is made High Rotation Speed along axle center, will produce linearity or concentric circles grinding track in polished metal surface like this, affect grinding efficiency and amount of grinding, the present invention is by changing the concentricity of power transmission shaft 4 connecting bolts 5, making power transmission shaft 4 and mill 1 be eccentric is connected, mill 1 is made eccentric rotary in grinding, produce linearity or concentric circles grinding track in can avoiding grinding, can cover the grinding vestige of last time when grinding next time.
