Abstract
The utility model discloses a device for simultaneously machining inner threads and outer threads of a one-way valve. The device for simultaneously machining the inner threads and the outer threads of the one-way valve comprises a screw tap sleeve, wherein a screw tap is arranged in the center of the screw tap sleeve, a screw die sleeve capable of horizontally moving is connected to the outer diameter of the screw tap sleeve in a sleeved mode, a reset spring is arranged between the screw die sleeve and the screw tap sleeve, a long groove is formed in the screw die sleeve, a screw fixed on the screw tap sleeve is arranged in the long groove, screw dies are arranged in the screw die sleeve, and the screw dies and the screw tap are concentrically installed. The device can be used for simultaneously machining the inner threads and the outer threads, and largely improves work efficiency.
Description
Technical field
The utility model relates to a kind of check valve internal and external threads simultaneous machining device.
Background technology
At present, our seen check valve on market, the internal and external threads on it is all generally that separate machined completes, and this mode has increased a procedure undoubtedly, causes manufacturing cost to increase, and operating efficiency reduces, and haves much room for improvement.
Addressing these problems is extremely urgent as from the foregoing!
In view of this, the inventor has done deep research, and by feat of the experience of being engaged in for many years relevant industries and practice, design a kind of check valve internal and external threads simultaneous machining device, can solve deficiency of the prior art, can process internal and external threads, operating efficiency improves greatly simultaneously, and this case produces thus.
The utility model content
The purpose of this utility model is to provide a kind of check valve internal and external threads simultaneous machining device, can process internal and external threads simultaneously, and operating efficiency improves greatly.
Check valve internal and external threads simultaneous machining device, it is characterized in that: comprise the screw tap cover, center at the screw tap cover is provided with screw tap, a die sleeve that can move horizontally of socket on the external diameter of screw tap cover, and being provided with back-moving spring between die sleeve and screw tap cover, described die sleeve is provided with elongated slot, is provided with in elongated slot and is fixed on the screw that screw tap puts, be provided with screw die in die sleeve, described screw die and screw tap be concentric installs setting.
Further, be provided with annular boss on screw tap cover outer wall.
The beneficial effects of the utility model: the utility model is a die sleeve of socket on the external diameter of screw tap cover, screw tap and screw die are to install and arrange with one heart, die sleeve is enclosed within screw tap and puts and can only move horizontally, and can not rotate, because can only move horizontally with screw confinement plate facing.Processing time, because the pitch of two screw threads is different, so die sleeve can move forward automatically, to guarantee the pitch of screw thread.Hence one can see that, and the utility model, in actual process, reduces by a procedure, has improved efficiency, has reduced cost.
Wherein screw effect: the one, fixing screw tap; The 2nd, the horizontally-guided bar of die sleeve.
Wherein, the setting of annular boss, effect that can the backer, after completing processing, reset to herein by back-moving spring, increases work efficiency.In addition, also can improve the installation stability of die sleeve.
As from the foregoing, the utility model can be processed internal and external threads simultaneously, and operating efficiency improves greatly.
In order further to explain the technical solution of the utility model, below by specific embodiment, the utility model is elaborated.
The accompanying drawing explanation
Fig. 1 is cross-sectional view of the present utility model.
Fig. 2 is the structural representation that the utility model is overlooked direction.
The specific embodiment
As depicted in figs. 1 and 2, the utility model relates to a kind of check valve internal and external threads simultaneous machining device, it is characterized in that: comprise screw tap cover 1, center at screw tap cover 1 is provided with screw tap 2, a die sleeve that can move horizontally 3 of socket on the external diameter of screw tap cover 1, and be provided with back-moving spring 4 between die sleeve 3 and screw tap cover 1, described die sleeve 3 is provided with elongated slot 5, be provided with the screw 6 be fixed on screw tap cover 1 in elongated slot 5, be provided with screw die 7 in die sleeve 3, described screw die 7 arranges with the concentric installation of screw tap 2.
Further arrange, at screw tap, overlap on 1 outer wall and be provided with annular boss 8.
More than that the technical scheme that the utility model embodiment is provided is described in detail, having applied specific case herein sets forth principle and the embodiment of the utility model embodiment, the explanation of above embodiment, be only applicable to the principle that the utility model embodiment is understood in help; , for one of ordinary skill in the art, according to the utility model embodiment, on the specific embodiment and range of application, all can change to some extent, in sum, this description should not be construed as restriction of the present utility model simultaneously.
