Embodiment Construction

[0028] The present invention will be further described below with reference to the accompanying drawings.

[0029] Such as Figure 1 to Figure 5 As shown, a rubber-lined butterfly valve stem extrusion assembly fixture includes a sliding device and a fixing device for fixing the valve body 25 on one side of the sliding device. The sliding device includes a transmission mechanism and an extrusion mechanism for extruding the valve stem. and a moving mechanism, the extruding mechanism is connected with a transmission mechanism, and the transmission mechanism is arranged above the moving mechanism.

[0030] The moving mechanism includes a base plate 1, a guide rail 2, a ball bearing 3, a roller 4 sliding along the guide rail and a roller shaft 5, the guide rail 2 is fixedly connected to the base plate 1, and the roller 4 is connected to the roller shaft 5 through the ball bearing 3. One side of the roller shaft 5 is provided with a roller fixing plate 6 for fixing the roller 4, an...

Abstract

The invention discloses a valve rod extruding assembly fixture for a butterfly valve with rubber lining, which comprises a sliding mechanism and a fixing mechanism which is arranged at one side of the sliding mechanism and is used for fixing a valve body, wherein the sliding mechanism comprises a transmission gear, an extruding device for extruding a valve rod and a shifting device, the extruding device is connected with the transmission gear, and the transmission gear is arranged above the shifting device. The valve rod extruding assembly fixture for the butterfly valve with rubber lining has the following advantages that the labor intensity is effectively reduced, the production efficiency is increased, an oil cylinder and a telescopic connection sleeve are adopted for extruding, so the installation stress of the valve rod is uniform, no impacting phenomenon is generated, a valve seat is not easily damaged, and the product quality is ensured.

Description

technical field [0001] The invention relates to an extruding mechanism, in particular to an extruding and assembling fixture for a valve stem of a rubber-lined butterfly valve. Background technique [0002] At present, the method of manual knocking is mainly used as the assembly method of the rubber-lined butterfly valve, but this assembly method has the following defects: [0003] 1. When tapping manually, it is necessary to tap with tools such as rubber hammers. For large-sized assemblies, the labor intensity is high and the efficiency is low during assembly; [0004] 2. Due to the uneven impact force during manual knocking, the rubber-lined valve seat around the valve stem is prone to damage; [0005] 3. The vibration caused by manual knocking makes the center of the aligned valve plate and valve body move in irregular directions, and the valve stem is not easy to enter the valve body; [0006] 4. There are uncertain safety factors in manual knocking. Contents of the ...
