Valve assembling device

Abstract

According to the valve assembling device, a valve body is placed on a first grabbing station, then a ball valve is placed on a placing position on a placing disc, and then a first telescopic air cylinder is started to convey the placing disc to the position below a second clamping jaw; at the moment, a second clamping jaw can move on a second electric track to enable a placement disc to be located below the second clamping jaw, then the second clamping jaw clamps the ball valve and places the ball valve into a valve body on a first grabbing station, and then the first electric track drives the first clamping jaw to grab the valve body assembled with the ball valve; at the moment, the second telescopic air cylinder is started to bring the press-fitting station to the position below the first clamping jaw, then the first clamping jaw places the valve body assembled with the ball valve on the press-fitting station, then the second telescopic air cylinder is driven again to start to bring the press-fitting station to the position below the press-fitting head, and then the hydraulic cylinder is started to drive the press-fitting head to descend to carry out press-fitting on the ball valve and the valve body. A finished product is taken out after press fitting is completed; and then the actions are repeated. Therefore, the labor is reduced, and the accuracy is also improved.

Description

Technical Field

[0001] This invention belongs to the field of valve assembly technology, and particularly relates to a valve assembly device. Background Technology

[0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, and regulate and control the parameters (temperature, pressure, and flow rate) of the transported medium. Based on their function, they can be divided into shut-off valves, check valves, regulating valves, etc. Valves are control components in fluid transport systems, possessing functions such as shut-off, regulation, flow diversion, backflow prevention, pressure stabilization, flow splitting, or overflow pressure relief. Valves used in fluid control systems range from the simplest shut-off valves to various valves used in extremely complex automated control systems, with a wide variety of types and specifications. Valves can be used to control the flow of various types of fluids, including air, water, steam, various corrosive media, mud, oil, liquid metals, and radioactive media. Valves are also classified according to their material, such as cast iron valves, cast steel valves, stainless steel valves (201, 304, 316, etc.), chrome-molybdenum steel valves, chrome-molybdenum-vanadium steel valves, duplex steel valves, plastic valves, and non-standard customized valves.

[0003] When assembling existing valves, the ball valve is usually placed manually on the valve body, and then a pressure rod is used to hammer the ball valve into the corresponding position in the valve body. Each assembly process can usually only assemble one valve. Moreover, when manually hammering the ball valve into the valve, human beings cannot make precise control, which can easily damage the ball valve. The manual assembly process is too time-consuming and inefficient, making it difficult to achieve mass production. Workers are also prone to hand injuries from working for long periods of time. Summary of the Invention

[0004] This invention provides a valve assembly device, which aims to solve the problems mentioned in the background art.

[0005] The present invention is implemented as follows: a valve assembly device includes a base, a ball valve gripping assembly, and a pressing assembly;

[0006] The base is provided with two opposing support columns, and a crossbeam is provided between the two support columns. A first electric track and a second electric track are provided on the crossbeam, and a first gripper is provided on the first electric track and a second gripper is provided on the second electric track. A first gripping station is provided below the crossbeam.

[0007] The ball valve gripping assembly includes a bracket, a placement plate on the bracket, and a ball valve inside the placement plate;

[0008] The pressing assembly includes a hydraulic cylinder, the output end of which is connected to a pressing head, and a pressing station is provided below the pressing head.

[0009] Preferably, the bracket is provided with a first telescopic cylinder, and the output end of the first telescopic cylinder is connected to the placement tray.

[0010] Preferably, the pressing assembly further includes a pressing frame, the hydraulic cylinder is fixedly mounted on the top of the pressing frame, and the pressing frame is also provided with the pressing station.

[0011] Preferably, the pressing frame is provided with a second telescopic cylinder, and the output end of the second telescopic cylinder is connected to the pressing station.

[0012] Preferably, the pressing frame is provided with a slide rail, and the pressing station slides on the slide rail under the drive of the second telescopic cylinder.

[0013] Preferably, the placement plate has multiple placement positions, and the ball valve is accommodated inside each placement position.

[0014] Preferably, the bracket is provided with a slide rail, and the placement tray slides on the slide rail under the drive of the first telescopic cylinder.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] The valve body is placed on the first gripping station, and then the ball valve is placed on the placement plate. The first telescopic cylinder is then activated to move the placement plate below the second gripper. The second gripper can then move along the second electric track to position the placement plate below it. The second gripper then picks up the ball valve and places it into the valve body on the first gripping station. The first electric track then drives the first gripper to pick up the valve body with the assembled ball valve. At this point, the second telescopic cylinder is activated to bring the pressing station below the first gripper. The first gripper then places the valve body with the assembled ball valve into the pressing station. The second telescopic cylinder is then activated again to bring the pressing station below the pressing head. The hydraulic cylinder then lowers the pressing head to press the ball valve and valve body together. After pressing, the finished product is removed. This process is then repeated. This reduces manual labor and increases accuracy. Attached Figure Description
