Abstract
The utility model provides a first flange device in car. Mainly solve present small -bore valve first flange is most in and process on the boring machine, not only process consuming timely, moreover when the flange of the processing back, be difficult to the problem guaranteed with special cutter and roughness. The utility model provides a first flange device in car comes both ends to carry out the clamping to the valve body through the live center with lathe chuck connection's locating lever, and the clamping is simple, fixes a position accurately, and the chasing speed is obvious for boring machine processing promotes, has both improved production efficiency, can guarantee size and roughness again. In addition, as preferred, as long as in lathe steady turning diameter allowed band, meet the valve product of different bores, only need to change and go up the locating lever and can carry out and switch processing.
Description
Technical field
The utility model belongs to valve manufacture field, is specifically related to head flange device in a kind of car.
Background technology
Smaller diameter valve generally refers to the valve of inside nominal diameter DN<40mm.The middle head flange of present smaller diameter valve is processed mostly on boring machine, not only processes consuming time, and process the back side flange time, with special tool and roughness be difficult to ensure.
Utility model content
In order to overcome the deficiency of background technology, the utility model provides head flange device in a kind of car, and the middle head flange mainly solving present smaller diameter valve is processed mostly on boring machine, not only processes consuming time, and process the back side flange time, with special tool and roughness be difficult to ensure problem.
The technical scheme that the utility model adopts is:
Head flange device in a kind of car, comprises rotating lathe chuck, described lathe chuck is connected with backstay, and described backstay one end is used for removably connecting and synchronous axial system with valve body;
Also comprise tailstock base, described tailstock base is provided with live center, and described live center and described backstay are coaxially arranged and the first through-hole wall snap fit of being provided with of front end and valve body;
Also comprise the lathe tool be arranged on knife rest, described lathe tool for on valve body in head flange outer face is corresponding arranges.
Described middle head flange is provided with the second through hole, and described body cavity is stretched into through described second through hole in described backstay one end; Also comprise locking nut, described locking nut and described backstay threaded engagement and press in described valve interior wall.
Described tailstock base is also provided with the handwheel for regulating described live center flexible.
Also pad is provided with between described locking nut and described valve interior wall.
Described backstay is provided with wearing layer.
The beneficial effects of the utility model are: the utility model provides head flange device in a kind of car, come two ends by live center and the backstay that is connected with lathe chuck and clamping is carried out to valve body, clamping is simple, accurate positioning, and cutting speed obviously promotes relative to Boring machine processing, both enhanced productivity, and size and roughness can be ensured again.In addition, as preferably, as long as in lathe tactical diameter allowed band, run into the valve products of different bore, backstay and practicable switching processing need only be replaced with.
Accompanying drawing explanation
Fig. 1 is the schematic front view of the utility model embodiment.
Fig. 2 is Figure 1A place close-up schematic view.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail: as shown in the figure, head flange device in a kind of car, comprise rotating lathe chuck 1, described lathe chuck 1 is connected with backstay 2, described backstay 2 one end is used for removably connecting and synchronous axial system with valve body 5; Also comprise tailstock base 7, described tailstock base 7 is provided with live center 6, and described live center 6 and described backstay 2 be coaxial to be arranged and the first through hole 51 inwall snap fit of being provided with of front end and valve body 5; Also comprise the lathe tool 81 be arranged on knife rest 8, described lathe tool 81 for on valve body 5 in head flange 3 outer face is corresponding arranges.Lathe chuck is driven by power source and rotates, power source can be motor etc., the utility model provides head flange device in a kind of car, come two ends by live center and the backstay that is connected with lathe chuck and clamping is carried out to valve body, clamping is simple, accurate positioning, and cutting speed obviously promotes relative to Boring machine processing, both enhanced productivity, and size and roughness can be ensured again.In addition, as preferably, as long as in lathe tactical diameter allowed band, run into the valve products of different bore, backstay and practicable switching processing need only be replaced with.
In the utility model, as shown in the figure, described middle head flange 3 is provided with the second through hole 31, and described valve body 5 inner chamber is stretched into through described second through hole 31 in described backstay 2 one end; Also comprise locking nut 4, described locking nut 4 is with described backstay 2 threaded engagement and press in described valve body 5 inwall.During assembling, backstay stretches in valve body, is then pressed on the inwall of valve body with locking nut, and easy to assembly, result of use is good.
In the utility model, as shown in the figure, described tailstock base 7 is also provided with the handwheel 71 for regulating described live center 6 flexible.Live center can be made to stretch out or take in by rotating handwheel, can adopt screw thread to realize here, structure is simple, and easy to adjust, result of use is good.
In the utility model, as shown in the figure, pad 41 is also provided with between described locking nut 4 and described valve body 5 inwall.More firm when assembling, there will not be and rock, result of use is better.
In the utility model, as shown in the figure, described backstay 2 is provided with wearing layer.Wearing layer can be made for high-abrasive material, as stellite etc.Longer service life.
Embodiment should not be considered as restriction of the present utility model, but any improvement done based on spirit of the present utility model, all should within protection domain of the present utility model.
