[0003] In the current existing technology, the quick clamping device used for valve processing is mainly composed of a fixed base, a support frame, an arc-shaped clamping plate and other components. Through the cooperation between these components, the valve can be clamped and fixed quickly and stably to improve the overall work efficiency during valve processing and production.

[0004] The existing quick clamping device for valve processing needs to be polished by a grinder at both ends of the valve during the valve production process so that the valve can be better and tightly connected later. However, the valve will vibrate and deviate during the polishing process, so it is necessary to use a clamping device to clamp and fix it. Some valve clamping devices are often clamped and fixed by the staff by turning the fastening bolts. However, the operation of clamping and fixing the valve by turning the fastening bolts back and forth is cumbersome, resulting in a decrease in the overall efficiency of valve processing and production, thereby increasing the labor of the staff. Therefore, in view of the above problems, a quick clamping device for valve processing is proposed. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1 and Figure 2 As shown, a quick clamping device for valve processing comprises a fixing seat 1; a mounting frame 11 is fixedly connected to the top of the fixing seat 1; a servo motor 12 is fixedly connected to the top of the fixing seat 1; a first bidirectional screw rod 13 is fixedly connected to the output end of the servo motor 12; a first pulley 14 is fixedly connected to the other end of the first bidirectional screw rod 13; a second pulley 15 is rotatably connected to a side wall of one side of the fixing frame 11; a transmission belt 16 is sleeved on the inner sides of the first pulley 14 and the second pulley 15; the inner side wall of the fixing frame 11 is opened A threaded hole 17 is provided; a second bidirectional screw rod 18 is rotatably connected to the inner side of the threaded hole 17; the other end of the second bidirectional screw rod 18 is connected to the second pulley 15; a pair of guide columns 19 are fixedly connected to the inner side wall of the mounting frame 11; a pair of sliders 110 are slidably connected to the outer side wall of the guide column 19; the sliders 110 are fixedly connected to the arc-shaped clamping blocks 111 on the side walls close to each other; a valve 112 is provided on the top of the fixing seat 1; a grinder 113 is fixedly connected to the inner top of the mounting frame 11; when working: The servo motor 12 is started to drive the first bidirectional screw rod 13 to drive the first pulley 14 to rotate together. During the rotation of the first pulley 14, the second pulley 15 can be driven to rotate in the same direction through the transmission belt 16. During the rotation of the second pulley 15, the second bidirectional screw rod 18 can be driven to rotate inside the threaded hole 17. Because the second bidirectional screw rod 18 is connected to the slider 110, and the slider 110 is connected to the arc clamping block 111, during the rotation of the second bidirectional screw rod 18, the slider 110 and the arc clamping block 111 are moved toward the side close to the valve 112. When the inner side wall of the arc clamping block 111 moves to fit the surface of the valve 112, the valve 112 can be quickly clamped and fixed, thereby reducing the work of clamping and fixing the valve by rotating the fastening bolts back and forth, which is cumbersome to operate, resulting in a decrease in the overall efficiency of the valve processing and production process, thereby reducing the labor of the staff; after the valve 112 is clamped and fixed, the grinder 113 can be used to grind the two ends of the valve 112.

[0024] like Figure 1 and Figure 4As shown, a dust box 2 is fixedly connected to the top of the mounting frame 11; a first connecting pipe 21 is connected to a side wall of one side of the dust box 2; an air pump 22 is fixedly connected to the other end of the first connecting pipe 21; a second connecting pipe 23 is fixedly connected to the bottom of the air pump 22; a dust suction port 24 is fixedly connected to the end of the second connecting pipe 23 away from the air pump 22; during operation: a large amount of dust is generated at both ends of the valve 112 during the grinding work, and the air suction pump 22 is started to allow the dust generated during the grinding of the valve 112 to enter the dust box 2 through the dust suction port 24, the second connecting pipe 23 and the first connecting pipe 21, thereby improving the working environment around the valve 112 during the grinding, reducing the large amount of dust generated when grinding the two ends of the valve 112, causing the dust to float in the air, which is easy to cause the staff to inhale it into the body, thereby improving the overall safety of the staff at work.

[0025] like Figure 1 , Figure 2 and Figure 3 As shown, a pair of first slide grooves 3 are provided on the top of the fixing seat 1; a slide column 31 is slidably connected inside the first slide groove 3; a scraper 32 is fixedly connected to a side wall of one side of the slide column 31; the scraper 32 is threadedly connected to the first bidirectional screw rod 13; a pair of connecting grooves 33 are provided on the top of the fixing seat 1; a fixing box 34 is fixedly connected to the bottom of the fixing seat 1; a box door 35 is rotatably connected to a side wall of one side of the fixing box 34; when working: when the grinding of both ends of the valve 112 is completed, the servo motor 12 is started to drive the first bidirectional screw rod 13 to reverse, Because the first bidirectional screw rod 13 and the scraper 32 are connected to each other, during the rotation of the first bidirectional screw rod 13, the first slide groove 3, the slide column 31 and the scraper 32 cooperate with each other to make the pair of scrapers 32 move away from each other. During the movement of the scraper 32, the debris that falls on the top of the fixed seat 1 when the valve 112 is polished can be pushed into the inner side of the connecting groove 33 and fall into the fixed box 34, thereby improving the cleanliness of the top surface of the fixed seat 1 and improving the overall work efficiency of the staff when cleaning the debris on the top of the fixed seat 1.

[0026] like Figure 2As shown, a pair of second slide grooves 4 are provided at the bottom of the inner side of the fixed box 34; the inner sides of the second slide grooves 4 are slidably connected to the storage box 41; a handle 42 is fixedly connected to the side wall of one side of the storage box 41; during operation: through the storage box 41 set inside the fixed box 34, the scraper 32 can make the debris fall directly into the storage box 41 through the connecting groove 33 during the process of cleaning the debris. When the debris collected in the storage box 41 needs to be cleaned, the box door 35 is rotated so that it no longer seals the side wall of the fixed box 34. Because the storage box 41 and the handle 42 are connected to each other, the handle 42 is pulled to make the storage box 41 move to the outside through the second slide groove 4 and detach from the fixed box 34, so that the debris in the storage box 41 can be quickly poured out, thereby improving the overall work efficiency of the staff when cleaning the debris in the storage box 41, and improving the cleanliness of the inside of the storage box 41.

[0027] like Figure 4 As shown, one end of the dust suction port 24 is fixedly connected to a porous protective cover 5; when working: when the vacuum pump 22 drives the dust suction port 24 to absorb and collect the dust generated when the valve 112 is polished, the porous protective cover 5 is set to prevent the debris from being absorbed by the dust suction port 24, thereby reducing the debris from being absorbed into the dust collecting box 2 through the dust suction port 24, the second connecting pipe 23 and the first connecting pipe 21, which may easily cause the vacuum pump 22 to be damaged, thereby improving the working life of the vacuum pump 22.

[0028] like Figure 2 As shown, the side wall of the arc-shaped clamping block 111 close to the valve 112 is fixedly connected with an arc-shaped elastic plate 6; when working: the arc-shaped elastic plate 6 is made of elastic material, and when the arc-shaped clamping block 111 clamps and fixes the valve 112, the arc-shaped elastic plate 6 first contacts with the valve 112, and the arc-shaped elastic plate 6 is in a squeezed state, so that the arc-shaped clamping block 111 is more tightly clamped when fixing the valve 112, thereby improving the overall stability of the valve 112 during grinding work.

[0029] like Figure 3 As shown, the scrapers 32 are fixedly connected with cleaning brushes 7 on the side walls close to each other. When working, the cleaning brush 7 moves along with the scraper 32. When the cleaning brush 7 moves, the dust and impurities adhered to the surface of the first bidirectional screw rod 13 can be cleaned, thereby improving the cleanliness of the surface of the first bidirectional screw rod 13.

[0030] Working principle: start the servo motor 12 to drive the first bidirectional screw 13 to drive the first pulley 14 to rotate together. During the rotation of the first pulley 14, the second pulley 15 can be driven to rotate in the same direction through the transmission belt 16. During the rotation of the second pulley 15, the second bidirectional screw 18 can be driven to rotate inside the threaded hole 17. Since the second bidirectional screw 18 is connected to the slider 110, and the slider 110 is connected to the arc clamping block 111, during the rotation of the second bidirectional screw 18, the slider 110 and the arc clamping block 111 are moved toward the side close to the valve 112. When the inner wall of the arc clamping block 111 moves to fit the surface of the valve 112, the valve 112 can be quickly clamped and fixed. The effect is reduced, thereby reducing the cumbersome operation of clamping and fixing the valve by rotating the fastening bolts back and forth, resulting in a decrease in the overall efficiency of the valve processing and production process, thereby reducing the labor of the staff; after the valve 112 is clamped and fixed, the grinder 113 can be used to grind the two ends of the valve 112; a large amount of dust will be generated when grinding the two ends of the valve 112, and the vacuum pump 22 is started to allow the dust generated when grinding the valve 112 to enter the dust collecting box 2 through the dust suction port 24, the second connecting pipe 23 and the first connecting pipe 21, thereby improving the working environment around the valve 112 when grinding, reducing the large amount of dust generated when grinding the two ends of the valve 112, causing the dust to float In the air, it is easy for workers to inhale it into their bodies, thereby improving the overall safety of workers at work; when the grinding of both ends of the valve 112 is completed, the servo motor 12 is started to drive the first bidirectional screw 13 to reverse. Because the first bidirectional screw 13 and the scraper 32 are connected to each other, during the rotation of the first bidirectional screw 13, the first slide groove 3, the slide column 31 and the scraper 32 cooperate with each other, so that a pair of scrapers 32 move away from each other. During the movement of the scraper 32, the debris that falls on the top of the fixed seat 1 when the valve 112 is ground can be pushed into the inner side of the connecting groove 33 and fall into the fixed box 34, thereby improving the cleanliness of the top surface of the fixed seat 1 and improving the safety of workers when cleaning. The overall work efficiency of the top of the fixed seat 1 is improved; by setting the storage box 41 inside the fixed box 34, the scraper 32 can make the scraper 32 drop directly into the storage box 41 through the connecting groove 33 during the process of cleaning the scraper 32. When the scraper 32 needs to clean the scraper 32, the box door 35 is rotated so that it no longer seals the side wall of the fixed box 34. Because the storage box 41 and the handle 42 are connected to each other, the handle 42 is pulled to move the storage box 41 to the outside through the second slide groove 4 and detach from the fixed box 34, so that the scraper 32 can quickly pour out the scraper 32, thereby improving the overall work efficiency of the staff when cleaning the scraper 32, and improving the cleanliness of the inside of the storage box 41.When the vacuum pump 22 drives the dust suction port 24 to absorb and collect the dust generated when the valve 112 is polished, the porous protective cover 5 can prevent the debris from being absorbed by the dust suction port 24, thereby reducing the possibility that the vacuum pump 22 is damaged when the debris is absorbed into the dust collection box 2 through the dust suction port 24, the second connecting pipe 23 and the first connecting pipe 21, thereby improving the service life of the vacuum pump 22; the arc elastic plate 6 is made of elastic material, and when the arc clamping block 111 clamps and fixes the valve 112, the arc elastic plate 6 first contacts the valve 112, and the arc elastic plate 6 is in a squeezed state, so that the arc clamping block 111 is more tightly clamped when the valve 112 is fixed, thereby improving the overall stability of the valve 112 during the polishing work; during the movement of the scraper 32, the cleaning brush 7 moves with it, and when the cleaning brush 7 moves, the dust and impurities adhered to the surface of the first bidirectional screw rod 13 can be cleaned, thereby improving the cleanliness of the surface of the first bidirectional screw rod 13. ;

Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
