Description

Technical Field

[0001] This invention relates to the field of integrated drilling and grinding technology, and more specifically to an integrated drilling and grinding device for processing stop valves. Background Technology

[0002] In traditional gate valve manufacturing, drilling and grinding are usually performed separately, requiring different equipment. This fragmented processing method not only increases operational complexity but also leads to low production efficiency. In contrast, integrated drilling and grinding devices combine drilling and grinding functions into one unit, allowing multiple processing steps to be completed on a single machine. This significantly shortens the processing cycle and improves production efficiency. Using an integrated device reduces equipment investment; since it integrates drilling and grinding functions, companies do not need to purchase two separate machines, saving on equipment purchase costs. Furthermore, it improves the quality of gate valves and reduces scrap and rework rates, further lowering production costs. In addition, integrated devices reduce labor costs; due to easier operation, companies can reduce the number of operators or lower their skill requirements, further reducing production costs. Integrated drilling and grinding devices typically offer high flexibility and adjustability, allowing for adjustments and optimizations to meet diverse market demands.

[0003] The integrated drilling and grinding device for gate valve processing generally involves preparatory work first, then starting the drilling mechanism, feeding the drill bit, then starting the grinding mechanism, adjusting the grinding position, grinding, then checking the processing quality, cleaning the equipment, and shutting down the equipment.

[0004] Currently, the integrated drilling and grinding equipment used for gate valve processing only includes two main processes: drilling and grinding. Drilling is followed by grinding. During drilling, large debris is generated and gets stuck in the drilled hole. The debris carries the heat from drilling and is then ground, which undoubtedly greatly delays the grinding progress. In addition, cleaning the drilled debris and dust will undoubtedly pollute the environment and affect the health of workers if inhaled. Summary of the Invention

Detailed Implementation

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The integrated drilling and grinding device for processing stop valves involved in the present invention is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Reference Figure 1 , 34. The present invention provides an integrated drilling and grinding device for processing a stop valve, including a support base 1, the support base 1 including a base 101, the base 101 having a bottom cavity 102 inside, a sealing plate 103 at the top of the bottom cavity 102, a support shaft 104 at the bottom of the bottom cavity 102, a rotating clamp assembly 2 rotatably connected inside the support base 1, a stop valve body 10 movably connected above the rotating clamp assembly 2, a support venting cylinder 4 above the stop valve body 10, a filter pipe 5 fixedly connected above the support venting cylinder 4, an air storage tank 6 fixedly connected to the tail of the filter pipe 5, an exhaust assembly 7 fixedly connected between the air storage tank 6 and the support base 1, and a cleaning assembly 3, a drilling assembly 8, and a grinding assembly 9 rotatably connected inside the support venting cylinder 4. The cleaning component 3 includes a first internal gear 301, a first rotating ring 302 fixedly connected to the bottom of the first internal gear 301, a first row fan 303 fixedly connected around the first internal gear 301, a first external gear 304 meshing with the inside of the first row fan 303, a connecting shaft 306 keyed to the center of the first external gear 304, a blowing and brushing component 305 fixedly connected to the bottom of the connecting shaft 306, a plurality of continuous discs 307 arrayed outside the connecting shaft 306, a first gear 309 connected to the outside of the continuous discs 307, a second motor 308 keyed to the first gear 309, a third motor 3010 rotatably connected to the top of the connecting shaft 306, and a first vent pipe 3011 provided outside the first row fan 303. In this embodiment, it should be specifically noted that when the first gear 309 is stationary, the continuous disc 307 and the first gear 309 are automatically locked together.

[0029] The main difference between this embodiment and the prior art is that this embodiment uses the flow of gas and the rotation of the exhaust fan to generate negative pressure to absorb metal debris and iron powder generated during drilling, cleaning and grinding, thereby absorbing dust and metal debris during drilling and cleaning and solving the environmental pollution problem generated during drilling and grinding. Specifically, it includes the rotating clamp assembly 2, cleaning assembly 3, drilling assembly 8 and grinding assembly 9. The above structure is the main structure of this embodiment. It solves the problem that the waste chips stuck in the drill hole will increase the grinding progress, removes the chips that carry the heat generated by the drill hole, and reduces the problem of excessive ellipticity caused by thermal expansion and contraction during grinding. The gas storage tank 6 is an existing structure. The specific structure and connection method of the gas storage tank 6 will not be described in detail in this embodiment.

[0030] Reference Figure 2 and 5The rotating clamp assembly 2 includes a first motor 201, which is fixedly connected to the base 101. The shaft of the first motor 201 is keyed to a drive shaft 202. A driven shaft 203 is meshed with one side of the drive shaft 202. A rotating table 204 is keyed inside the driven shaft 203. A steering hydraulic clamp 205 is connected above the rotating table 204. The filter pipe 5 includes a four-way connector 501, which is fixedly connected to the supporting ventilator 4. A transition pipe 504 is fixedly connected to the upper part of the four-way connector 501. The air inlet of the transition pipe 504 is sequentially provided with a filter assembly 502 and a first one-way valve 503. The transition pipe 504 is connected to the air storage tank 6.

[0031] In this embodiment, it should be specifically explained that after drilling, the cleaning component 3, drilling component 8, and grinding component 9 are restored to their original positions. The first motor 201 drives the drive shaft 202, which is fixedly connected to it, to rotate. The drive shaft 202 drives the driven shaft 203, which is meshed with it, to rotate. The driven shaft 203 drives the rotating table 204, which is keyed to it, to rotate. The rotating table 204 drives the shut-off valve body 10 to rotate to the corresponding position below the cylinder 401. The dust and debris after drilling continuously enter the interior of the gas storage tank 6 through the first one-way valve 503 after being filtered by the filter component 502 from the four-way valve 501.

[0032] Reference Figure 6 The supporting ventilator 4 includes a cylindrical tube 401. The bottom of the cylindrical tube 401 has a plurality of circumferentially arranged tool passage holes 402 for cleaning components. A rotating groove 403 is provided around the tool passage holes 402. A plurality of ventilation grooves 404 are arranged around the rotating grooves 403. The ventilation grooves 404 penetrate the bottom, while the rotating grooves 403 do not penetrate the bottom. The tool passage holes 402 are fixedly connected to the periphery of the ventilation grooves 404. The supporting plate 405 is L-shaped, and the horizontal plate of the supporting plate 405 is located at the ventilation... Above the air groove 404, the horizontal plate of the support plate 405 is provided with a shaft ventilation hole 406. The shaft ventilation hole 406 is coaxial with the corresponding tool passage hole 402. The shaft ventilation hole 406 is surrounded by a dispersion hole 407. The horizontal plate of the shaft ventilation hole 406 is connected to the top of the cylinder 401 by a vertical rod. The top of the cylinder 401 is provided with a honeycomb-shaped ventilation hole 409. The ventilation hole 409 corresponds to the tool passage hole 402 with the ring-shaped distribution of the object. The cleaning shaft passage hole 408 is coaxial with the shaft ventilation hole 406.

[0033] In this embodiment, it should be specifically noted that the airflow of the cleaning component 3, the drilling component 8, and the grinding component 9 all passes through the tool passage hole 402 and the vent hole 409.

[0034] Reference Figure 7 and Figure 9The drilling assembly 8 includes a drill bit 801. A shaft of a drilling motor 802 is fixedly connected to the top of the drill bit 801. A drilling hydraulic cylinder 807 is fixedly connected to the top of the housing of the drilling motor 802. A second external gear 803 is keyed to the shaft of the drilling motor 802. The second external gear 803 meshes with a second internal gear 804. A second rotating ring 805 is fixedly connected to the bottom of the second internal gear 804. A second exhaust fan 806 is fixedly connected to the periphery of the second internal gear 804. A second vent pipe 808 is fixedly connected between the upper and lower parts of the cylinder 401. The second vent pipe 808 surrounds... The grinding assembly 9, located around the second row fan 806, includes a grinding head 901. The top of the grinding head 901 is fixedly connected to the shaft of a grinding motor 902. The top of the housing of the grinding motor 902 is fixedly connected to a grinding hydraulic cylinder 907. The shaft of the grinding motor 902 is keyed to a third external gear 903. The third external gear 903 meshes with a third internal gear 904. The bottom of the third internal gear 904 is fixedly connected to a third rotating ring 905. The periphery of the third internal gear 904 is fixedly connected to a third row fan 906. A third vent pipe 908 is fixedly connected between the upper and lower parts of the cylinder 401.

[0035] In this embodiment, it should be specifically explained that: the drilling hydraulic cylinder 807 is activated, which pushes the drilling motor 802 downward. When the drill bit 801 contacts the platform of the shut-off valve body 10, the drilling motor 802 is activated to begin drilling. The shaft of the drilling motor 802 starts to drive the drill bit 801, which is fixedly connected to it, to rotate. The drilling hydraulic cylinder 807, equipped with a pressure sensor, senses the pressure change and adjusts the pressure on the drill bit 801 in real time to make the drilling force appropriate. At the same time, the rotation of the shaft of the drilling motor 802 drives the keyed second external gear 803 to rotate. The second external gear 803 drives the second internal gear 804, which is meshed with it, to rotate. The second internal gear 804 drives the second exhaust fan 806 to rotate. The rotation of the second exhaust fan 806 generates negative pressure. At the same time, the dust and metal debris generated during drilling are sucked into the ventilation slot 404 under the negative pressure generated by the rotation of the second exhaust fan 806. The second vent pipe 808 activates the grinding hydraulic cylinder 907, which in turn drives the grinding motor 902 downwards. When the grinding head 901 contacts the table surface of the shut-off valve body 10, the grinding motor 902 is activated to begin drilling. The shaft of the grinding motor 902 drives the grinding head 901, which is fixedly connected to it, to rotate. The grinding hydraulic cylinder 907, equipped with a pressure sensor, senses the pressure change and adjusts the pressure on the grinding head 901 in real time to ensure appropriate drilling force. Simultaneously, the rotation of the shaft of the grinding motor 902 drives the keyed third external gear 903 to rotate. The third external gear 903 drives the third internal gear 904, which meshes with it, to rotate. The third internal gear 904 drives the third row fan 906 to rotate. The rotation of the third row fan 906 generates negative pressure. At the same time, dust and metal debris generated during drilling are sucked into the third vent pipe 908 through the vent groove 404 under the negative pressure generated by the rotation of the second row fan 806.

[0036] Reference Figure 8 The air blowing and brushing assembly 305 includes an air-venting cylinder 3051, which is barrel-shaped. Several air blowing holes 3052 are connected and circumferentially connected to the inner wall of the air-venting cylinder 3051. Brush bristles 3053 are fixedly connected to the outside of the air-venting cylinder 3051.

[0037] In this embodiment, it should be specifically explained that: the air source inside the air blowing and brushing component 305 blows air through the air blowing hole 3052, and the brush bristles 3053 clean the inside of the drill hole, causing large metal chips to fall to the ground and small dust and metal fragments to remain suspended.

[0038] Reference Figure 10 The exhaust assembly 7 includes an exhaust plate 701, a through pipe 702 passing through the top of the exhaust plate 701, branch pipes 703 on both sides of the through pipe 702, and an exhaust pipe 704 in front of the branch pipes 703, the exhaust pipe 704 passing through the front surface.

[0039] In this embodiment, it should be specifically explained that: the one-way valve inside the gas storage tank 6 releases the gas inside the gas storage tank 6 from the gas storage tank 6, and enters through the through pipe 702, passes through the branch pipe 703, and finally exits through the outlet pipe 704. The discharged gas has a certain pressure and will pre-clean the debris on the support base 1.

[0040] The working principle of this invention is as follows: the negative pressure generated by the flow of gas and the rotation of the exhaust fan is used to absorb the metal debris and iron powder generated during drilling, cleaning and grinding. This absorbs the dust and metal debris generated during drilling and cleaning, solving the environmental pollution problem generated during drilling and grinding. Furthermore, the cleaning process is added between the drilling component 8 and the grinding component 9. Removing the debris stuck in the drill hole will improve the grinding progress. Removing the debris that carries the heat generated by drilling will reduce the ellipticity deviation caused by thermal expansion and contraction during grinding.

[0041] The specific steps are as follows: First, place the shut-off valve body 10 to be processed on the rotating table 204 and make it coaxial with the cylinder 401, with the drilling position of the shut-off valve body 10 located directly below the drill bit 801. Start the steering hydraulic clamp 205 to fix the rotating table 204. Other shut-off valve bodies 10 may have different numbers of large holes. Here, we take drilling three holes on one surface as an example. To begin drilling the first hole, the drilling hydraulic cylinder 807 is activated. The drilling hydraulic cylinder 807 pushes the drilling motor 802 downwards. Once the drill bit 801 contacts the platform of the shut-off valve body 10, the drilling motor 802 is activated to begin drilling. The shaft of the drilling motor 802 begins to rotate the drill bit 801, which is fixedly connected to it. The drilling hydraulic cylinder 807, equipped with a pressure sensor, senses pressure changes and adjusts the pressure on the drill bit 801 in real time to ensure appropriate drilling force. Simultaneously, the rotation of the drilling motor 802's shaft drives the keyed second external gear 803 to rotate, which in turn drives the meshing second internal gear 803. When gear 804 rotates, the second internal gear 804 drives the second row fan 806 to rotate. The rotation of the second row fan 806 generates negative pressure. At the same time, the dust and metal debris generated during drilling are drawn into the second vent pipe 808 through the vent groove 404 under the negative pressure generated by the rotation of the second row fan 806. They then enter the four-way valve 501 through the vent hole 409. After passing through the filter assembly 502, the clean air after removing the dust and metal debris is stored in the air tank 6. The pressure inside the air tank 6 increases. When the first hole of the shut-off valve body 10 is drilled, the drilling hydraulic cylinder 807 retracts the second rotating ring 805 and returns to the starting position. The second hole is drilled. The first motor 201 is started, driving the drive shaft 202, which is fixedly connected to it, to rotate. The drive shaft 202 drives the driven shaft 203, which is meshed with it, to rotate. The driven shaft 203 drives the rotating table 204, which is keyed to it, to rotate. The rotating table 204 rotates the shut-off valve body 10 to a suitable position below the cylinder 401. The suitable position is when the shut-off valve body 10 has rotated 90 degrees. At the same time, the air-blowing brush assembly 305 is positioned directly above the first drilled hole, and the drill bit 801 is positioned directly above the second drilling position. The subsequent process is the same as the first hole. Simultaneously, the second motor 308 is started, driving the first gear 309 to rotate, which in turn drives the continuous disc 307 downward, causing the connecting shaft 306 and the air-blowing brush assembly 305 to move downward. When the air-blowing brush assembly 305 begins to contact the first drilled hole, the third motor 3010 is started, driving the connecting shaft 306, which is meshed with it, to rotate. The first external gear 304 and the air-blowing brush assembly 305 are rotated. The air source inside the air-blowing brush assembly 305 blows air through the air-blowing hole 3052, and the brush bristles 3053 clean the inside of the drilled hole, causing large metal chips to fall to the ground and small dust and metal debris to be suspended. At the same time as the first external gear 304 rotates, the first exhaust fan 303 is rotated to generate negative pressure, which causes small dust and metal debris to enter the first ventilation pipe 3011 through the ventilation groove 404, and enter the four-way 501 through the ventilation hole 409. After the filter assembly 502 removes the dust and metal debris, the clean air enters the air storage tank 6 for storage. The pressure inside the air storage tank 6 increases. When the second hole of the shut-off valve body 10 is drilled, the drilling hydraulic cylinder 807 retracts the second rotating ring 805 back to the starting position. At the same time, the second motor 308 rotates in the opposite direction, driving the first gear 309 to rotate and driving the air-blowing brush assembly 305 to be retracted upward to the original position. The third hole is drilled. The first motor 201 is started, driving the rotating table 204 to rotate the shut-off valve body 10 to a suitable position below the cylinder 401 (90 degrees in the same direction as the shut-off valve body 10). Simultaneously, the air-blowing and brushing assembly 305 is positioned directly above the second hole, and the drill bit 801 is positioned directly above the third hole. The subsequent process is the same as the second hole. Simultaneously, the grinding hydraulic cylinder 907 is started, pushing the grinding motor 902 downwards. When the grinding head 901 contacts the table surface of the shut-off valve body 10, the grinding motor 902 is started to begin drilling. The shaft of the grinding motor 902 begins to drive the grinding head 901, which is fixedly connected to it, to rotate. The grinding hydraulic cylinder 907, equipped with a pressure sensor, senses pressure changes and adjusts the grinding head 901 in real time. The pressure of 1 ensures the drilling force is appropriate. At the same time, the rotation of the shaft of the grinding motor 902 drives the key-connected third external gear 903 to rotate. The third external gear 903 drives the meshing third internal gear 904 to rotate. The third internal gear 904 drives the third row fan 906 to rotate. The rotation of the third row fan 906 generates negative pressure. At the same time, the dust and metal debris generated by drilling are sucked into the third vent pipe 908 through the vent groove 404 under the negative pressure generated by the rotation of the second row fan 806. They then enter the four-way 501 through the vent hole 409. After passing through the filter component 502, the clean air after removing the dust and metal debris enters the interior of the air storage tank 6 for storage. The pressure inside the air storage tank 6 increases. When the drilling of the third hole of the shut-off valve body 10 is completed, the entire device returns to its original position. Subsequently, the hydraulic clamp 205 releases the shut-off valve body 10 and removes the shut-off valve body 10. The one-way valve inside the gas tank 6 releases the gas inside the gas tank 6 from the gas tank 6, and enters through the through pipe 702, passes through the branch pipe 703, and finally exits through the outlet pipe 704. The discharged gas has a certain pressure and will pre-clean the debris on the support base 1.

[0042] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
