Problems solved by technology

[0002] At present, in order to prevent the pressure cap on the valve body from being loosened in the prior art, after the pressure cap is tightened, an anti-demolition spring retaining ring needs to be installed in the side of the pressure cap to prevent the pressure cap from being loosened. Loosening, falling off or even dismantling occurs during use, but when the anti-demolition spring retaining ring is installed, it is manually installed by workers, so the work efficiency is low; In the mouth of the pressing cap, workers not only have to work hard but also need to use sharp tools to install the anti-demolition spring retaining ring in place.
Therefore, it is easy for workers to be scratched by tools during the installation process.
Therefore, the existing technology has the disadvantages of low work efficiency and prone to work-related injuries.

Embodiment 1

[0019] Such as figure 1 , figure 2 , Figure 4 and Figure 5 The automatic assembly equipment for the anti-dismantling spring retaining ring of a gas cylinder valve pressure cap shown includes a base 1, a turntable 2 and a pressure rod 3, the turntable 2 is rotatably connected to the base 1, and the turntable 2 There is a limit hole 2.1 matching the shape of the pressure cap 12, that is, the cross-sectional shape of the limit hole 2.1 is the same as the hexagonal shape of the pressure cap 12, and it can also be understood that the limit hole 2.1 can limit the valve downward and circumferentially. Limit, specifically means that the limit hole 2.1 is a stepped hole, and the shape of the limit hole 2.1 matches the shape of the pressure cap 12, that is, the free end of the valve stem 15 can be inserted into the limit hole 2.1, and one end of the pressure cap 12 Part of the part is also inserted into the limit hole 2.1, and the limit hole 2.1 has the function of downward limit ...

Embodiment 2

[0026] Such as image 3As shown, a cylinder 11 is provided between the other end of the pressure rod 3 and the base 1 (an oil cylinder can also be used to replace the cylinder). The cylinder 11 includes a fixed end and a telescopic end. The fixed end of the cylinder 11 end is fixed on the base 1, and the telescopic end of the cylinder 11 is hinged with the other end of the compression rod 3, which can also be understood as the free end of the piston rod of the cylinder 11 is hinged with the other end of the compression rod 3, and the axis of the piston rod is connected with the other end of the compression rod 3. The end face of the base 1 is vertical, of course the cylinder 11 is connected with the air source, and generally the air source is connected with the control cabinet 9 or the control device of the cylinder 11 is connected with the control cabinet 9 . All the other structures are the same as that of Example 1.

Abstract

The invention discloses an automatic assembly apparatus for an anti-detachment spring retainer ring of a gas cylinder valve compression cap. The. The automatic assembly apparatus comprises a base (1), a turntable (2) and a compression bar (3), wherein the turntable (2) is rotatably connected to the base (1); a limiting hole (2.1) matched with the compression cap in shape is formed on the turntable (2); the middle part of the compression bar (3) is articulated to the base (1); and a downward projection (3.1) is arranged at one end of the compression bar (3) and located above the limiting hole (2.1). Compared with the prior art, the automatic assembly apparatus is characterized in that firstly, a valve body on which the anti-detachment spring retainer ring is placed and the compression cap is screwed down is placed in the limiting hole of the turntable; next, one part of the anti-detachment spring retainer ring is pressed into the side opening of the compression cap through the projection part of the compression bar, and simultaneously, the state of the compression bar at this moment is kept; then, after the turntable is rotated, and a valve rotates along with the turntable by one circle, the compression bar is capable of automatically and completely pressing the anti-detachment spring retainer ring into the side opening of the compression cap; and finally, the other end of the compression bar is pressed down, so that the projection part of the compression bar is lifted, and then the valve can be taken out. Therefore, a worker does not need to contact with the valve body in the mounting process and only needs to rotate the turntable, and even when the compression bar drops, the compression bar does not contact the hand of the worker, so that the safety of the worker in operation is guaranteed, the worker is not easy to suffer from industrial injury, and the working efficiency is also improved.
