Surface treatment device for hydraulic valve body

Abstract

The present invention relates to a surface treatment device for a hydraulic valve body applied in the field of valve processing. When grinding the valve block, the valve block is placed between a fixed transverse clamp and a fixed longitudinal clamp, and a transverse chuck and a longitudinal chuck are driven by an air push rod to move in the direction of the fixed transverse clamp and the fixed longitudinal clamp respectively to squeeze the valve block to fix it, and then a grinding mechanism grinds the upward side of the valve block. After grinding, the transverse chuck and the longitudinal chuck are away from the valve block, and an electric push rod close to the longitudinal flipping hole moves upward to lift the valve block to tilt it until the valve block completes a lateral flip of 90 degrees, and then the transverse chuck and the longitudinal chuck fix the valve block again for grinding. The above reciprocating movement can grind the four transverse surfaces of the valve block, and similarly, the two longitudinal surfaces can be polished to complete the grinding of all surfaces of the valve block. Through the above arrangement, the grinding of all valve surfaces can be completed without frequent manual flipping of the valve block, thereby improving the grinding efficiency of the valve block.

[0001] The invention relates to a surface treatment device for a hydraulic valve body, and in particular to a surface treatment device for a hydraulic valve body applied in the field of valve processing. Background Art

[0002] A hydraulic valve is an automated component operated by pressurized oil. It is controlled by the pressure oil of a pressure regulating valve and is usually used in combination with an electromagnetic pressure regulating valve. It can be used to remotely control the on / off of oil, gas, and water pipeline systems in hydropower stations. It is often used for clamping, controlling, lubricating, and other oil circuits.

[0003] The valve body of a hydraulic valve is usually rectangular. During processing, six sides need to be polished. A clamp is used to clamp the valve block during polishing. After polishing one side, the valve block is manually turned over and then fixed again until all six sides of the valve block are polished. The above polishing method requires a lot of manpower and therefore needs further improvement. Summary of the invention

[0004] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is that after one side of the valve body is polished, the valve block needs to be manually turned over and then fixed again, which consumes a lot of manpower and is not convenient for batch processing.

Through the above arrangement, the valve block can be better assisted to complete the longitudinal flipping.

[0008] As a further improvement of the present application, the sides of the transverse chuck and the longitudinal chuck are provided with sunken grooves, and the interior of the sunken grooves is fixedly connected with an electromagnet.

The above reciprocating movement can grind the four transverse surfaces of the valve block, and similarly, the two longitudinal surfaces can be polished to complete the grinding of all surfaces of the valve block. Through the above arrangement, the grinding of all valve surfaces can be completed without frequent manual flipping of the valve block, thereby improving the grinding efficiency of the valve block.

[0022] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0023] The first implementation method:

[0024] Figure 1-8 A surface treatment device for a hydraulic valve body is shown, comprising a bearing seat 1 and a grinding mechanism 2, wherein a fixing seat 3 is fixedly connected to the upper side of the bearing seat 1, and a mutually perpendicular fixed transverse clamping plate 4 and a fixed longitudinal clamping plate 5 are fixedly connected to the top of the fixing seat 3, a longitudinal slide groove 7 perpendicular to the fixed longitudinal clamping plate 5 is opened at one end of the fixing seat 3, and a transverse slide groove 6 perpendicular to the fixed transverse clamping plate 4 is opened at the other end of the fixing seat 3, and a transverse slide groove 8 and a longitudinal slide groove 9 are respectively slidably connected to the inner walls of the transverse slide groove 6 and the longitudinal slide groove 7, and the transverse slide groove 8 and the longitudinal slide groove 9 are respectively slidably connected to the inner walls of the transverse slide groove 6 and the longitudinal slide groove 7. The top of the longitudinal slider 9 is fixedly connected with a transverse chuck 801 and a longitudinal chuck 901, respectively; the bottom ends of the fixed seat 3 near the transverse slider 8 and the longitudinal slider 9 are fixedly connected with air push rods 10; the telescopic ends of the two air push rods 10 are fixedly connected with the bottom ends of the transverse slider 8 and the longitudinal slider 9, respectively; the fixed seat 3 is provided with a longitudinal flip hole 11 and a transverse flip hole 12 near the fixed transverse splint 4 and the fixed longitudinal splint 5, respectively; one end of the bearing seat 1 near the longitudinal flip hole 11 and the transverse flip hole 12 is fixedly connected with an electric push rod 13.

[0025] When grinding the valve block, the valve block is placed between the fixed transverse clamping plate 4 and the fixed longitudinal clamping plate 5, and the air push rod 10 drives the transverse clamping head 801 and the longitudinal clamping head 901 to move and squeeze the valve block in the direction of the fixed transverse clamping plate 4 and the fixed longitudinal clamping plate 5 to fix it, and then the grinding mechanism 2 grinds the upward side of the valve block. After grinding, the transverse clamping head 801 and the longitudinal clamping head 901 are away from the valve block, and the electric push rod 13 close to the longitudinal turning hole 11 moves upward to lift the valve block to tilt it until the valve block is completed. Flip it horizontally 90 degrees, and then fix the valve block again with the transverse chuck 801 and the longitudinal chuck 901 for grinding. The above reciprocating movement can grind the four horizontal surfaces of the valve block. Similarly, when grinding the two longitudinal surfaces, the electric push rod 13 close to the transverse flipping hole 12 moves upward to lift the valve block to complete the longitudinal flip of 90 degrees, thereby completing the grinding of all surfaces of the valve block. Through the above arrangement, there is no need to manually flip the valve block frequently to complete the grinding of all valve surfaces, thereby improving the grinding efficiency of the valve block.

[0026] The second implementation method:

[0027] Figure 4-10 A surface treatment device for a hydraulic valve body is shown. Different from the first embodiment, a transverse groove 14 parallel to the fixed transverse clamping plate 4 and a longitudinal groove 15 parallel to the fixed longitudinal clamping plate 5 are opened at one end of the fixed seat 3. The inner walls of the transverse groove 14 and the longitudinal groove 15 are slidably connected with a transverse blocking baffle 1401 and a longitudinal blocking baffle 1501, respectively. The bottom end of the bearing seat 1 is fixedly connected with two symmetrically arranged lifters 16. The telescopic ends of the two lifters 16 are fixedly connected with the bottom ends of the transverse blocking baffle 1401 and the longitudinal blocking baffle 1501, respectively.

[0028] When the valve block is flipped laterally, the longitudinal baffle 1501 is driven by the lift 16 to move completely upward, and the transverse baffle 1401 moves upward 0-1 cm. At this time, the longitudinal baffle 1501 can limit the valve block to prevent the valve block from longitudinal displacement, and the transverse baffle 1401 can prevent the valve block from longitudinal sliding when flipping. Similarly, when the valve block is flipped longitudinally, the transverse baffle 1401 moves completely upward, and the longitudinal baffle 1501 moves upward 0-1 cm. Through the above settings, the flipping of the valve block can be limited, thereby improving the flipping effect of the valve block.

[0029] A transverse flip plate 17 is arranged on the lower side of the supporting seat 1, and a longitudinal flip plate 18 is arranged on the lower side of the transverse flip plate 17. One end of the transverse flip plate 17 is hinged to one end of the supporting seat 1, and an upper hydraulic rod 1701 is hinged between the other end of the transverse flip plate 17 and the supporting seat 1, and one end of the longitudinal flip plate 18 is hinged to one end of the transverse flip plate 17, and a lower hydraulic rod 1801 is hinged between the other end of the longitudinal flip plate 18 and one end of the transverse flip plate 17. When the valve block flips laterally, the supporting seat 1 is lifted by the upper hydraulic rod 1701 to tilt the supporting seat 1, which can better assist the valve block to complete the transverse flipping. When the valve block flips longitudinally, the transverse flip plate 17 is lifted by the lower hydraulic rod 1801 to tilt the supporting seat 1, which can better assist the valve block to complete the longitudinal flipping.

[0030] The sides of the transverse chuck 801 and the longitudinal chuck 901 are both provided with an indented groove 19, and the interior of the indented groove 19 is fixedly connected with an electromagnet 20. When the valve block needs to be flipped laterally and the transverse chuck 801 is away from the valve block, the electromagnet 20 can be briefly started and stopped to pull the valve block outward a short distance, thereby reserving space for the flipping of the valve block and avoiding the valve block from being squeezed by the fixed transverse clamp 4 during rotation.

[0031] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
