Abstract
The utility model discloses a valve block clamping tool. The tool comprises a round fixture, a clamping block and a clamping screw, wherein a mounting hole for placing a valve block is formed in the middle of the round fixture; one side of the mounting hole is communicated with a placing groove capable of accommodating the clamping block; a thread through hole matched with the clamping screw is formed in the external surface of the round fixture; the clamping screw is pressed against the clamping block through the thread through hole; and the clamping block clamps the valve block under the action of acting force of the clamping screw. Pre-marking is not needed when a plane and a center hole of the valve block are machined by the tool, so that work efficiency is improved, the position accuracy of the center hole is improved, and the surface of the valve block is difficult to damage.
Description
Technical field
The utility model relates to a kind of clamping tool, is specifically related to a kind of clamping tool for clamping valve piece.
Background technology
When the plane of processing valve piece and centre bore, generally need first to be clipped on the lathe valve is packaged by chuck, process its plane, need behind the plane machining workpiece is taken off, the position of centre bore is determined in line, needs go up the processing that lathe carries out centre bore again.Adopt this processing mode to have following shortcoming
1, operation is many, waste of manpower, material resources;
2, because the valve piece is modified, and its hardness is not very high, directly uses the chuck clamping, crush easily valve piece surface;
3, the hole site precision of determining by line is not high.
The utility model content
The technical problem that (one) will solve
The technical problems to be solved in the utility model provide a kind of process simple, the hole site precision high and be difficult for crushing the clamping tool of valve piece.
(2) technical scheme
For solving the problems of the technologies described above, the utility model provides a kind of valve packaged folder instrument, it comprises circular clamp, fixture block and pinching screw, the middle part of circular clamp offers for the installing hole of placing the valve piece, one side of installing hole is communicated with the standing groove that can hold fixture block, offer the tapped through hole that matches with pinching screw on the outer surface of circular clamp, pinching screw is supported fixture block by tapped through hole, and fixture block is the pinched valve piece under the active force of pinching screw.
Wherein, this fixture block is installed in the standing groove by hold-down screw, is set with spring on the hold-down screw, and an end of spring is resisted against on the outer surface of circular clamp, and its other end is resisted against the head of hold-down screw.
(3) beneficial effect
Compared with prior art, use the utility model that plane and the centre bore of valve piece are processed, do not need prior line, improved operating efficiency, improved the positional precision of centre bore, and be difficult for crushing valve piece surface.
Description of drawings
Fig. 1 is the Facad structure schematic diagram of the packaged folder instrument of the utility model valve.
Fig. 2 is the A-A generalized section of Fig. 1.
The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is described in further detail.Following examples are used for explanation the utility model, but can not be used for limiting scope of the present utility model.
The structure of the packaged folder instrument of the utility model valve as shown in Figure 1, its A-A cross-section structure as shown in Figure 2, the packaged folder instrument of this valve comprises circular clamp 1, fixture block 2 and pinching screw 5, the middle part of circular clamp 1 offers installing hole 11, one side of installing hole 11 is communicated with the standing groove 12 that can hold fixture block 2, offer the tapped through hole that matches with pinching screw 5 on the outer surface of circular clamp 1, pinching screw 5 is supported fixture block 2 by tapped through hole, and fixture block 2 is the pinched valve piece under the active force of pinching screw 5.This fixture block 2 and valve piece both sides plane-plane contact have avoided fixture block 2 to crush the valve piece.
This fixture block 2 is installed in the standing groove 12 by 2 hold-down screws 4, all is set with spring 3 on each hold-down screw 4, and an end of this spring 3 is resisted against on the outer surface of circular clamp 1, and its other end is resisted against the head 41 of hold-down screw 4.
Add man-hour, the valve piece is inserted in the installing hole, overcome acting force of the spring by screwing pinching screw, promote fixture block and clamp this valve piece, after machining, unscrew pinching screw, make fixture block restore next time the beginning position in the effect of spring, can take out easily the valve piece this moment.Adopt plane and the centre bore of this clamping tool processing valve piece, do not need prior line, improved operating efficiency, improved the positional precision of centre bore, and be difficult for crushing valve piece surface.
It below only is preferred embodiment of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
