[0023] 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.

[0024] like Figure 1 , 2As shown in Figure 5, a hole processing auxiliary device for metal casting valves includes a drilling machine body 1; a placing table 11 is installed in the middle of the drilling machine body 1; two groups of electric push rods 12 are installed on the top of the placing table 11; the output end of the electric push rod 12 is fixedly connected to a clamping plate 13; two groups of connecting rods 14 are fixedly connected to the middle of the clamping plate 13; a first pull rope 15 is hinged at the end of the connecting rod 14, and the first pull rope 15 is slidably arranged in the middle of the placing table 11; a vertical block 16 is fixedly connected to the end of the first pull rope 15; a baffle 17 is fixedly connected to the middle of the vertical block 16, and the baffle 17 is slidably arranged in the middle of the placing table 11; when working, the staff needs to install the drilling machine body 1 in the working area, and then place the valve to be processed on the top of the placing table 11, and by setting two groups on the top of the placing table 11, and then turning on the switches of the two groups of electric push rods 12, the output end of the electric push rod 12 drives the clamping plate 13 to move until the middle of the clamping plate 13 is placed on the top of the placing table 11 After the valve is in contact, the valve can be fixed under the action of the extrusion force. At the same time, when the output end of the electric push rod 12 is clamping the valve, the connecting rod 14 at the end of the clamping plate 13 will move synchronously, and pull the first pull rope 15 during the movement, so that the first pull rope 15 slides on the inner wall of the placement table 11. At the same time, under the action of the vertical block 16, the baffle 17 will be pulled upward to move until the two groups of baffles 17 are unfolded. This step cooperates with the set clamping plate 13 to increase the speed of fixing the valve. At the same time, under the action of the two groups of unfolded baffles 17, the middle part of the baffle 17 will block the splashing residue generated by the drilling machine body 1 after the metal casting valve is processed, reduce the problem of hot metal impurities flying to the outside world and affecting nearby staff, improve the cleanliness of the working environment of the drilling machine body 1, and at the same time, the turned baffle 17 can block the sparks generated by the rotation of the middle part of the drilling machine body 1, reducing the damage to the eyes of nearby staff.

[0025] like Figure 2 and 3As shown, the output end of the electric push rod 12 is fixedly connected to a connecting block 2; the top of the connecting block 2 is fixedly connected to a shell 21; a fixing piece 22 is provided on the top of the shell 21; a first spring 23 is fixedly connected to the inner wall of the fixing piece 22; a first slide column 24 is fixedly connected to the end of the first spring 23, and the first slide column 24 is slidably arranged on the inner wall of the fixing piece 22; a pressure plate 25 is connected to the torsion spring at the end of the first slide column 24, and the middle part of the pressure plate 25 is arranged in an arc shape; when working, by arranging the pressure plate 25 at the output end of the clamping plate 13, when the clamping plate 13 gradually approaches the valve, the protruding pressure plate 25 will contact the middle part of the valve, and after contacting the arc surface in the middle of the valve, it moves downward. The first spring 23 is bent, and continued pushing will stretch the middle part of the first spring 23, and generate a reverse force, thereby squeezing the valve body fixed in the middle part. Under the downward squeezing action of the two groups of pressure plates 25, the valve body can be reinforced. This step cooperates with the downwardly bent pressure plate 25 to improve the stability when fixing the spherical valve, and reduce the problem that the spherical valve is difficult to fix with only two groups of planar clamps 13. The accuracy of the output end in the middle of the drilling machine body 1 when opening the valve is improved, and the problem of valve position deviation during the opening process is reduced. The reaction force generated by the first spring 23 can be used to further improve the stability of the valve when it is fixed.

[0026] like Figure 3 and 4 As shown, the middle part of the housing 21 is rotatably connected with a rotating shaft 3; the top of the rotating shaft 3 is fixedly connected with a screw rod 31; the fixing member 22 is threadedly connected in the middle part of the screw rod 31; the side wall of the housing 21 is fixedly connected with a first slide column 24; the end of the fixing member 22 is fixedly connected with a second slide column 33, and the second slide column 33 is slidably arranged on the inner wall of the limit member 32; during operation, by providing a rotating rotating shaft 3 in the middle part of the housing 21, when the staff needs to adjust the working height of the fixing member 22, they can rotate the rotating shaft 3 by hand, so that the rotating shaft 3 can synchronously drive the screw rod 31 to rotate during the rotation process, thereby causing the fixing member 22 to move, and under the action of the second slide column 33, the fixing member 22 can only move up and down straightly until the working position of the fixing member 22 is adjusted. This step cooperates with the screw rod 31 to improve the flexibility of the fixing member 22 when it is used, and reduces the problem that the pressure plate 25 of a fixed height is difficult to contact the outer wall of the valve due to different valve models placed on the top of the placing table 11.

[0027] like Figure 3 and 4As shown, a reinforcing rod 4 is fixedly connected to the top of the screw 31; a cloth 41 is fixedly connected to the middle of the reinforcing rod 4; and a plurality of counterweights 42 are fixedly connected to the bottom of the cloth 41. During operation, by arranging the cloth 41 on the top of the screw 31, the counterweights 42 will expand to both sides under the action of rotational inertia when the staff rotates the rotating shaft 3, so that the cloth 41 presents an umbrella shape, and the impurities attached to the middle of the cloth 41 are thrown out. At the same time, after the rotation of the screw 31 is stopped, the counterweight 42 will hit the middle of the screw 31 under the action of gravity and generate a vibration force. This step can be combined with the cloth 41 to cover part of the middle area of ​​the screw 31 to reduce the adhesion of metal impurities. At the same time, the force of the counterweight 42 hitting the middle of the screw 31 can improve the cleanliness of the middle of the screw 31 and reduce the problem of large resistance when the screw 31 moves between the fixing member 22.

[0028] like Figure 2 and 5 As shown, the inner wall of the placement table 11 is fixedly connected with multiple groups of second springs 5; the end of the second spring 5 is fixedly connected with a rubber pad 51; the first pull rope 15 is arranged on the inner wall of the rubber pad 51; when working, by arranging multiple groups of second springs 5 ​​on the inner wall of the placement table 11, when the output end of the electric push rod 12 pulls the first pull rope 15 to move, the middle part of the first pull rope 15 will contact with the rubber pad 51, and squeeze the second spring 5 at the stressed end, and use the generated elasticity to correct the movement position of the first pull rope 15. This step, combined with the rubber pad 51 made of soft material, can reduce the problem of large surface wear when the first pull rope 15 slides on the inner wall of the placement table 11 and the middle part directly contacts the inner wall of the placement table 11, thereby improving the service life of the first pull rope 15. At the same time, the elastic second spring 5 will limit the working position of the first pull rope 15.

[0029] like Figure 1 and 2 As shown, the end of the baffle 17 is fixedly connected to a second pull rope 6; the middle of the second pull rope 6 is fixedly connected to a ball 61; when working, by arranging the second pull rope 6 in the middle of the two groups of baffles 17, the baffle 17 can drive the ball 61 to shake up and down under the action of inertia when it moves. This step, combined with the shaking ball 61, can improve the staff's observation of whether the clamp 13 fixes the valve, and further improve the accuracy of fixing the valve.

[0030] like Figure 3As shown, a plurality of groups of friction grooves 7 are provided in the middle of the rotating shaft 3, and the friction grooves 7 are arranged in a circular array in the middle of the rotating shaft 3; during operation, by providing the friction grooves 7 in the middle of the rotating shaft 3, when the staff member rotates the middle of the rotating shaft 3, his hand will contact the rotating shaft 3 before the rotating shaft 3, and this step, combined with the recessed rotating shaft 3, can enhance the friction force of the staff member when rotating the rotating shaft 3 and reduce the problem of hand slipping.

[0031] The working principle is that after the drilling machine body 1 is installed in the working area, the valve to be processed is then placed on the top of the placement table 11. Two groups of electric push rods 12 are set on the top of the placement table 11, and then the two groups of electric push rods 12 switches are turned on, so that the output end of the electric push rod 12 drives the clamping plate 13 to move until the middle of the clamping plate 13 contacts the valve placed on the top of the placement table 11, and the valve is fixed under the action of the extrusion force. At the same time, when the output end of the electric push rod 12 is clamping the valve, the connecting rod 14 at the end of the clamping plate 13 will move synchronously, and pull the first pull rope 15 during the movement, so that the first pull rope 15 slides on the inner wall of the placement table 11. At the same time, under the action of the vertical block 16, the baffle 17 will be pulled upward to move until the two groups of baffles 17 are unfolded. By providing a pressure plate 25 at the output end of the clamping plate 13, when the clamping plate 13 gradually approaches the valve, the protruding pressure plate 25 will contact the middle of the valve, and after contacting the arc surface in the middle of the valve, it will bend downward. After continuing to push, the middle of the first spring 23 will be stretched, and a reverse force will be generated, thereby squeezing the valve body fixed in the middle. Under the downward squeezing action of the two groups of pressure plates 25, the valve body can be reinforced. By providing a rotating shaft 3 in the middle of the shell 21, the staff needs to adjust the fixing member 22 When the work height is reached, the rotating shaft 3 can be rotated by hand, so that the rotating shaft 3 can synchronously drive the screw rod 31 to rotate during the rotation process, thereby causing the fixing member 22 to move. Under the action of the second sliding column 33, the fixing member 22 can only move up and down in a straight line until the working position of the fixing member 22 is adjusted. By arranging a cloth 41 on the top of the screw rod 31, when the staff rotates the rotating shaft 3, under the action of rotational inertia, the counterweight 42 will expand to both sides, so that the cloth 41 presents an umbrella shape, and the impurities attached to the middle of the cloth 41 are thrown out. At the same time, after the screw rod 31 stops rotating, the counterweight 42 will hit the In the middle of the screw 31, a vibration force is generated. By arranging multiple groups of second springs 5 ​​on the inner wall of the placement table 11, when the output end of the electric push rod 12 pulls the first pull rope 15 to move, the middle of the first pull rope 15 will contact the rubber pad 51, and squeeze the second spring 5 at the force-bearing end, and use the generated elasticity to correct the movement position of the first pull rope 15. By arranging a second pull rope 6 in the middle of the two groups of baffles 17, the baffle 17 can drive the ball 61 to shake up and down under the action of inertia when it moves. By arranging a friction pattern 7 in the middle of the rotating shaft 3, when the staff rotates the middle of the rotating shaft 3, his hand will contact the rotating shaft 3 before the rotating shaft 3.

[0032] The above shows and describes the basic principle, main features and advantages of the utility model. 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.
