[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] Example 1: As Figures 1 to 5 As shown in the embodiment of this utility model, a clamping device for valve string processing includes a worktable 1; a cavity 11 is provided in the middle of the worktable 1, and two sliding grooves 12 communicating with the cavity 11 are longitudinally spaced on the top of the worktable 1; two screws 14 are rotatably installed in the cavity 11, and the two screws 14 correspond one-to-one with the two sliding grooves 12 and are parallel to each other; two motors 13 are also fixedly installed in the cavity 11, and the two motors 13 are respectively connected to the two screws 14 for transmission; there are various ways to install the two screws 14, for example: one end of each screw 14 is concentrically fixedly connected to the output shaft of the corresponding motor 13, and the other end of each screw 14 is fitted with a bearing and rotatably connected to the side wall of the cavity 11 through the bearing; the ends of the two screws 14 that are far apart from each other are threaded with sliders 15, and the top of each slider 15 is fixedly connected with a sliding rod 16, and the upper end of each sliding rod 16 extends out of the sliding groove 12 and is fixedly connected with a clamping block 17.

[0024] Place the valve string to be processed onto the worktable 1. After adjusting the position of the valve string, start the motor 13. The motor 13 drives the screw 14 to rotate, causing the sliders 15 to slide on the screw 14. The sliders 15 drive the slide rods 16 to slide in the slide grooves 12, which in turn causes the clamping blocks 17 to move closer together to clamp the valve string. If the processing position of the valve string to be processed is not in the center of the valve string, the position of the valve string on the worktable 1 will be off-center. When fixing it, one of the motors 13 can be started first to position one side of the clamping block 17. After the setting is confirmed, another motor 13 is started to drive the screw 14 to rotate, and then the clamping block 17 on the other side pushes the valve string to contact the clamping block 17 on one side, and achieves the clamping effect. By setting two motors 13 to drive the screw 14 to rotate respectively, the slider 15 slides on the screw 14 to change the position of the clamping block 17. In this way, the valve string with different sizes can be flexibly adjusted and clamped. At the same time, when fixing the valve string whose processing position is off the center of the valve string, the processing center of the valve string can be aligned with the center of the worktable 1.

[0025] like Figure 3As shown, the opposite faces of the two clamping blocks 17 are provided with silica gel pads 2, and a plurality of magnetic strips 21 are fixedly installed in the silica gel pads 2. The two silica gel pads 2 are adsorbed on the corresponding clamping blocks 17 through the magnetic strips 21. When the clamping blocks 17 clamp the valve string, the silica gel pads 2 first contact the valve string and are then extruded and attached to the outer surface of the valve string. By arranging the silica gel pads 2, the valve string can be protected from being damaged and deformed due to excessive extrusion of the clamping blocks 17, and the uneven shape of the outer side of the valve string can be attached, thereby increasing the clamping force of the clamping blocks 17 on the valve string.

[0026] As shown in Figures 1 to 4 , two air guide pipes 3 are fixedly installed on the rear side of the top of the workbench 1, and the two ends of the two air guide pipes 3 are sealed and symmetrically arranged on the left and right sides of the workbench 1. The two air guide pipes 3 are each provided with a plurality of air holes 32 on the side facing the middle of the screw rod 14. During operation, the input ends of the two external air pipes 31 are connected to the air pump. The gas enters the air guide pipe 3 through the external air pipe 31 and is discharged from the air hole 32 to act on the processed valve string. The gas flow blows away the debris generated after processing. By arranging the external air pipe 31 to connect the gas, the gas acts on the surface of the processed valve string to blow away the debris generated during processing, avoiding the phenomenon that the debris causes the clamping block 17 to slip with the valve string, resulting in unstable clamping of the clamping block 17 on the valve string.

[0027] As shown in Figures 1 to 4 , two lighting lamps 4 are fixedly installed on the top of the two air guide pipes 3 on the side facing the middle of the screw rod 14. The air holes 32 on the two air guide pipes 3 are vertically spaced apart. Most of the valve string processing is completed by the mechanical arm. Workers need to check during this process, but the mechanical arm will cast a shadow on the processed valve string. The lighting lamp 4 illuminates it to reduce the shadow of the valve string and facilitate the worker to check the processing process of the mechanical arm.

[0028] As shown in Figures 1 to 5 , the workbench 1 is provided with an inclined light board 5 on the front side of the top, and the upper end of the light board 5 is inclined to the rear side of the workbench 1. The left and right sides of the light board 5 are fixedly installed with a support rod 51, and the lower ends of the two support rods 51 are fixedly connected with the workbench 1. The light of the lighting lamp 4 cannot irradiate the back of the valve string, and the light board 5 can reflect the light of the lighting lamp 4, and the reflected light can irradiate the back of the valve string.

[0029] Working principle: place the valve string to be processed on the workbench 1, adjust the position of the valve string, start the motor 13, the motor 13 drives the screw 14 to rotate, so that the sliding block 15 slides on the screw 14 respectively, the sliding block 15 drives the sliding rod 16 to slide in the sliding groove 12, and then drives the clamping block 17 to approach each other, clamping the valve string, if the processing position of the valve string to be processed is not in the center of the valve string, the position of the valve string on the workbench 1 will deviate from the center of the workbench 1, when fixing it, one of the motors 13 can be started first, the position of one side of the clamping block 17 is determined, and then the other motor 13 is started to drive the screw 14 to rotate, and then the other side of the clamping block 17 pushes the valve string to contact with one side of the clamping block 17 and realizes the clamping effect. By setting two motors 13 to drive the screw 14 to rotate respectively, the sliding block 15 slides on the screw 14 to change the position of the clamping block 17, so that the valve string of different sizes and different positions can be flexibly adjusted and clamped. At the same time, for the valve string whose processing position deviates from the center of the valve string, the center of the valve string processing can be corresponded to the center of the workbench 1 when it is fixed. When the clamping block 17 clamps the valve string, the silica gel pad 2 contacts the valve string first, and then is extruded and adheres to the outer surface of the valve string.

[0030] By setting the silica gel pad 2, the valve string can be protected to avoid over-extrusion of the clamping block 17, which can cause damage and deformation of the valve string. It can also adhere to the uneven shape of the outer side of the valve string, thereby increasing the clamping force of the clamping block 17 on the valve string. The external air pipe 31 is connected to the air pump, the gas enters the air guide pipe 3 through the external air pipe 31, and then is discharged from the air hole 32, acting on the valve string processing position. The airflow blows away the debris generated after processing, the gas is connected through the external air pipe 31, and the gas acts on the surface of the processed valve string through the air hole 32, blowing away the debris generated during processing, avoiding the phenomenon that the debris causes the clamping block 17 and the valve string to slip, causing the clamping block 17 to clamp the valve string unstably.

[0031] Most of the valve string processing is completed by the mechanical arm, and workers need to check during the process. The mechanical arm will cause shadow to the processed valve string, the illuminating lamp 4 illuminates it to reduce the shadow of the valve string, which is convenient for workers to check the processing process of the mechanical arm. The light of the illuminating lamp 4 cannot irradiate to the back of the valve string, the reflecting plate 5 can reflect the light of the illuminating lamp 4, and the reflected light can irradiate to the back of the valve string, so that the workers can check the valve string more comprehensively.

[0032] Example 2: The difference between example 2 and example 1 is that, as shown in Figures 1 to 5 The top of the workbench 1 on the front side of the reflecting plate 5 is provided with a collecting groove 6, and the lower end of the reflecting plate 5 is located in the enclosed area of the collecting groove 6. The airflow blown by the air hole 32 carries away the debris, which is guided by the reflecting plate 5, so that the debris falls into the collecting groove 6.
