Description

Technical Field

[0001] The utility model relates to the technical field of polishing devices, in particular to a valve plate production polishing device. Background Technique

[0002] The valve plate usually refers to the bottom connecting plate of various switching valves. Many mechanical devices in life need to use the valve plate. According to different uses, the valve plate can be divided into hydraulic valve plates, butterfly valve plates, and automotive valve plates, etc. The hydraulic valve plate is an automated component operated by pressure oil. It is controlled by the pressure oil of the distribution valve and is usually used in combination with an electromagnetic distribution valve. It can be used to remotely control the on-off of the oil, gas, and water pipeline systems in hydropower stations. The butterfly valve, also called a flap valve, is a simple-structured regulating valve. The butterfly valve used for the on-off control of the medium in low-pressure pipelines refers to a valve whose closing member (valve flap or butterfly plate) is a disc and rotates around the valve shaft to achieve opening and closing. During the production process of the valve plate, it is necessary to polish and grind the upper and lower surfaces of the valve plate before it can be put into use. The polishing process needs to be completed by a valve plate production polishing device. Most of the existing valve plate production polishing devices are prone to shaking of the valve plate during polishing, resulting in a reduction in the polishing quality of the valve plate, and most of them cannot polish the valve plate evenly, and the polishing effect is not good.

[0030] Working principle: First, place the valve plate on the placement plate 6, then start the first electric push rod 9. The output end of the first electric push rod 9 drives the first telescopic rod 10 to extend. The first telescopic rod 10 drives the limiting plate 7 to rotate upward and be parallel to the placement plate 6, thereby fixing the valve plate on the placement plate 6 and preventing the valve plate from shaking when the polishing disc 24 polishes the valve plate. Then start the second motor 22. The output end of the second motor 22 drives the driving rotating shaft 23 to rotate. The rotation of the driving rotating shaft 23 drives the polishing disc 24 to rotate. Subsequently, start the hydraulic rod 14. The output end of the hydraulic rod 14 drives the third telescopic rod 15 to retract. The retraction of the third telescopic rod 15 drives the installation frame 16 to descend. The descent of the installation frame 16 drives the polishing disc 24 to contact the valve plate and polish the valve plate. When it is necessary to adjust the polishing position of the valve plate, the first motor 18 can be started. The output end of the first motor 18 drives the driving rotating shaft 19 to rotate. The rotation of the driving rotating shaft 19 drives the threaded rod 20 to rotate. The rotation of the threaded rod 20 drives the threaded block 21 to move horizontally. The horizontal movement of the threaded block 21 drives the polishing disc 24 to polish the valve plate horizontally. At the same time, start the second electric push rod 12. The output end of the second electric push rod 12 drives the second telescopic rod 13 to push the support rod 5 to move longitudinally. The movement of the support rod 5 drives the slider 3 to slide in the first chute 2. At the same time, the longitudinal movement of the support rod 5 drives the valve plate on the placement plate 6 to move longitudinally. Thus, the longitudinal movement can cooperate with the horizontal movement of the polishing disc 24 to enable the valve plate to be polished evenly, thereby improving the polishing effect of the valve plate.
