Said driving mechanism comprises first spring that is arranged on the axle each intermediate plate applied thrust, is coated at the pressing plate of tapered portion and is used to drive the drive unit that pressing plate moves up and down, and said first spring is positioned on the axle of jointed shaft below.
Further; Also comprise the governor motion that is used for adjustable clamp cover upper-lower position, said governor motion comprises with the coaxial sliding axle that is connected of axle, is coated at sliding axle and the axle sleeve that is slidingly matched with its single-degree-of-freedom, the adjusting screw(rod) that cooperates with sleeve thread and two ends are fixedly connected on second spring on sliding axle and the adjusting screw(rod) end respectively;
Further, said adjusting screw(rod) is provided with locking nut;
Further, said axle is fixedly connected through radiation fins with sliding axle;
Further, said intermediate plate is two;
Further, said drive unit is a cylinder.
The beneficial effect of the utility model: chuck is used in the utility model valve grinding; It realizes clamping automatically and unclamping valve stem through intermediate plate and intermediate plate driving mechanism; Convenient mounting and clamping, clamping labour intensity is low, consuming time few, and this valve grinding is combined with power set with chuck; Can realize automatic grinding valve and valve retainer through the rotation of power set drive spindle, thereby the grinding precision and the grinding efficiency that can improve valve are high.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
Fig. 1 is the structural representation of the utility model valve grinding with chuck.
The specific embodiment
Fig. 1 is the structural representation of the utility model valve grinding with chuck.
As shown in the figure; Chuck is used in the present embodiment valve grinding; Comprise axle 1, be fixed in support bar 2 on the axle 1, be articulated at least two intermediate plates 3 on the support bar 2 and be used to drive the driving mechanism that intermediate plate 3 rotates around jointed shaft; Said intermediate plate 3 is formed the chuck of clamping valve stems, and the chuck end of jointed shaft top is provided with the clamping hole 4 adaptive and coaxial with axle 1 with valve stem, and the chuck of jointed shaft below is provided with a up-small and down-big tapered portion;
Said driving mechanism comprises first spring 5 that is arranged on the axle 1 each intermediate plate 3 applied thrust, is coated at the pressing plate 6 of tapered portion and is used to drive the drive unit 7 that pressing plate 6 moves up and down, and said first spring 5 is positioned on the axle of jointed shaft below.
The quantity of intermediate plate 3 is specially two in the present embodiment, and is simple in structure, is convenient to make; Certainly in different embodiments, the quantity of intermediate plate can also be for more than other number of two, like 3 or 4 etc.
In the present embodiment, said drive unit 7 is cylinder, and is simple in structure, is convenient to implement; Certainly drive unit 7 can also be other structure in different embodiments, and as can adopting motor-driven leading screw driving mechanism commonly used, but its embodiment is complicated than present embodiment.
Chuck is used in the utility model valve grinding; It realizes clamping automatically and unclamping valve stem through intermediate plate and intermediate plate driving mechanism; Convenient mounting and clamping, clamping labour intensity is low, consuming time few, and this valve grinding is combined with power set with chuck; Can realize automatic grinding valve and valve retainer through the rotation of power set drive spindle, thereby the grinding precision and the grinding efficiency that can improve valve are high.
As improvement to this embodiment; This valve grinding also comprises the governor motion that is used for adjustable clamp cover upper-lower position with chuck, and said governor motion comprises with the coaxial sliding axle that is connected of axle 18, is coated at sliding axle 8 and the axle sleeve 9 that is slidingly matched with its single-degree-of-freedom, is fixedly connected on second spring 11 on sliding axle 8 and adjusting screw(rod) 10 ends respectively with the adjusting screw(rod) 10 and the two ends of axle sleeve 9 threaded engagement.Through rotation adjusting screw rod 10, therefore the pretightning force between scalable valve and the valve retainer can adjust Grinding Quality and grinding efficiency through this governor motion.
