Description

Technical Field

[0001] The invention relates to the technical field of hydraulic valve processing, in particular to a valve hole deburring device for hydraulic valve processing. Background Art

[0002] The hydraulic valve is an automatic component operated by pressure oil. It is controlled by the pressure oil of the pressure regulating valve and is usually used in combination with the electromagnetic pressure regulating valve. It can be used to remotely control the on and off of the oil, gas and water pipeline systems of the hydropower station. After the valve hole of the hydraulic valve is drilled, in order to improve the processing quality, deburring equipment is needed to deburr the valve hole;

[0003] The current valve hole deburring equipment for hydraulic valve processing uses a magnet to adsorb the valve on the workbench, which has good stability and ensures the deburring effect;

[0004] However, in the actual operation process, the hydraulic valve to be deburred needs to be placed on the workbench first, fixed by magnet adsorption, and then deburred. After deburring, the grinding wheel needs to be pulled out from the valve hole, and then the deburred hydraulic valve is taken out from the workbench, and then the hydraulic valve is placed on the workbench again to continue deburring. In this way, a lot of working time is wasted after deburring until the next hydraulic valve is deburred, which reduces work efficiency. In addition, the valve hole of the hydraulic valve is deburred directly on the workbench, which causes the debris generated during the deburring process to easily remain in the valve hole, thereby reducing the quality of the deburring work.

The cleaning disc 24 is in a frustum shape. When the grinding wheel 19 moves upward, it drives the cleaning disc 24 at the top of the cleaning rod 23 to be inserted into the valve hole. In this way, after deburring, the downward movement of the grinding wheel 19 can drive the cleaning disc 24 to move downward close to the inner wall of the valve hole to scrape off the burrs attached to the valve hole.

After the upward movement, the height of the adjusting block 37 is higher than the height of the hydraulic valve on the conveyor belt 31. When the clamping plate 27 rotates to the conveyor belt 31, as the conveyor belt 31 continues to rotate, the hydraulic valve can be smoothly transported to the position between the two clamping plates 27 to clamp and load the material.

[0040] The debris shielding and collecting structure includes a shielding cylinder 44 installed in the middle of the processing table 1, a material discharge chute 45 connected to the shielding cylinder 44 is opened on the processing table 1, and horizontal plates 47 are installed on both sides of the material discharge chute 45 below the processing table 1.

During the deburring process, the burrs generated during the deburring process are collected on the processing table 1 through the shielding cylinder 44, thereby improving the quality of the working environment. In addition, the rotation of the rotating column 2 drives the scraper bar 46 to rotate closely against the processing table 1, pushing the debris on the processing table 1 to the material discharge chute 45, and discharging the debris from the material discharge chute 45 to the collecting frame 48 for collection, which is convenient for centralized processing.

[0041] The implementation principle of the valve hole deburring device for processing a hydraulic valve in the embodiment of the present invention is as follows: the second motor 29 on the bracket 28 is started to drive the roller 30 and the conveyor belt 31 to rotate, the conveyor belt 31 on the right side rotates in the direction close to the rotating column 2, and the conveyor belt 31 on the left side rotates in the direction away from the rotating column 2, and the second electric telescopic rod 26 on the cross plate 3 above the right conveyor belt 31 is started to drive the two clamping plates 27 to clamp and fix the hydraulic valve to be processed on the right conveyor belt 31, then, the first electric telescopic rod 7 on the fixed frame 4 is started to drive the lifting plate 6 to move upward on the guide rod 5, and one end of the insertion rod 10 is driven from the first vertical groove through the connecting rod 8. 12 slides into the first arc groove 13, and the first arc groove 13 wall is squeezed by one end of the rod 10 to drive the fixed cylinder 11 and the rotating column 2 to rotate as a whole, thereby rotating the hydraulic valve clamped on the right conveyor belt 31 toward the direction of the grinding wheel 19. When the rod 10 slides to the uppermost position of the first arc groove 13, the hydraulic valve after conveyance rotates to the position just above the grinding wheel 19. At this time, the lifting sleeve 9 continues to move upward on the fixed cylinder 11, driving one end of the rod 10 to slide upward in the second vertical groove 14. The rod 10 can limit the rotating column 2 and the hydraulic valve as a whole. At the same time, the first motor 21 is started to rotate through the first gear The wheel 20 and the second gear 22 drive the grinding wheel 19 to rotate, and the grinding wheel 19 is driven to be inserted into the valve hole to deburr the valve hole. After processing, the lifting plate 6 drives the grinding wheel 19 to move out of the valve hole on the guide rod 5, and in the process of moving down, the lifting plate 6 drives the insertion rod 10 to slide from the second vertical groove 14 to the second arc groove 15. The insertion rod 10 squeezes the groove wall of the second arc groove 15 to drive the rotating column 2 to rotate, and the next group of clamping structures on the cross plate 3 clamps the hydraulic valve to be deburred on the right conveyor belt 31. In this way, in the process of the grinding wheel 19 moving out of the valve hole, the deburred hydraulic valve can be driven to rotate to the conveyor belt on the left. On the belt 31, the clamping structure is loosened, and the hydraulic valve is unloaded by the conveyor belt 31 rotating on the left side. At the same time, the hydraulic valve to be deburred clamped on the lower clamping structure is rotated to the top of the grinding wheel 19, and the deburring process is continued. The working time is reasonably used and the work efficiency is improved. In the process of deburring, the burrs generated during the deburring process are collected on the processing table 1 through the shielding cylinder 44, so as to improve the quality of the working environment. The rotation of the rotating column 2 drives the scraper 46 to rotate close to the processing table 1, and pushes the debris on the processing table 1 to the unloading trough 45, and unloads from the unloading trough 45 to the collection frame 48 for collection, which is convenient for centralized processing.
