[0021] Figure 1 is a schematic structural diagram of the clamp fixture mechanism in the present utility model; Figure 2 is a usage state diagram of the clamp fixture mechanism in the present utility model; Figure 3 is a schematic structural diagram of the position detection mechanism in the present utility model. Please refer to Figures 1 to 3 As shown, a preferred embodiment is shown. A clamp fixture mechanism is shown, which includes a clamp seat 1 and two clamps 2 rotatably provided at one end of the clamp seat 1. It also includes a supporting clamp 4 and rollers 5. Two rollers 5 are respectively arranged on the sides of the two clamps 2 close to each other. Among them, through holes are formed in the clamps 2, and the rollers 5 are installed in the through holes through rotating shafts. The rotating shafts at both ends of the rollers 5 can be rotatably connected to the inner walls on both sides of the through holes. The two rollers 5 are arranged at intervals. One end of each clamp 2 is respectively rotatably connected to the clamp seat 1, and a supporting clamp 4 is respectively provided at the other end of each clamp 2, and the supporting clamp 4 is bent and arc-shaped. In this embodiment, please refer to Figure 2 As shown, among them, after the supporting clamp 4 is connected to the clamp 2, it can rotate following the clamp 2. Through the setting of the supporting clamp 4, the clamp 2 can clamp a pipe column with a large diameter. Rollers 5 are provided on the clamp 2, and there is an interval between the rollers 5. The two rollers 5 can abut against the outer wall of the pipe column, which is convenient for clamping the pipe column. And when the rollers 5 contact the outer wall of the pipe column, they can rotate, which is convenient for the movement of the pipe column, so that the pipe column can smoothly enter between the two rollers 5, which is convenient for clamping the rollers 5.
[0022] Further, as a preferred embodiment, a clamping block 6 is provided at one end of the supporting clamp 4, and a clamping groove is formed at the other end of the clamping pliers 2. The clamping block 6 is arranged in the clamping groove. After the supporting clamp 4 is clamped with the clamping groove through the clamping block 6, the clamping block 6 and the clamping pliers 2 can be further connected by bolts, so that the supporting clamp 4 and the clamping pliers 2 are fixedly connected.
[0023] Further, as a preferred embodiment, a connecting seat 7 is further included. A connecting seat 7 is respectively arranged on one side of the two clamping pliers 2 close to each other, and one end of the connecting seat 7 is rotatably connected to the clamping pliers 2. The connecting seat 7 can be a block structure, mainly used to connect the clamping pliers 2 and the piston rod of the air cylinder 3, so that when the piston rod expands and contracts, it can drive the connecting seat 7 to rotate, and then the connecting seat 7 drives the two clamping pliers 2 to rotate.
[0024] Further, as a preferred embodiment, an air cylinder 3 is further included. An air cylinder 3 is arranged inside the clamp seat 1, and the piston rod of the air cylinder 3 extends out of the clamp seat 1 and is hinged to the other end of the connecting seat 7. The air cylinder 3 is fixedly arranged inside the clamp seat 1, specifically, it can be arranged at a position inside the clamp seat 1 close to the clamping pliers 2. A connecting hole can be arranged at the end of the piston rod of the air cylinder 3 for hinging with the other end of the connecting seat 7 by means of a pin shaft. See Figure 1 As shown, during use, the PLC controller outside the through hole controls the operation of the air cylinder 3. When the piston rod of the air cylinder 3 extends, it will drive the two connecting seats 7 to drive the two clamping pliers 2 to open. When the pipe column enters between the two clamping pliers 2 and reaches the specified position, then the piston rod of the air cylinder 3 contracts, driving the two clamping pliers 2 to tighten, so as to realize the clamping of the pipe column.
[0025] Further, as a preferred embodiment, a position detection mechanism 8 is further included. A position detection mechanism 8 is arranged at one end of the clamp seat 1. The position detection mechanism 8 is located between the two clamping pliers 2 and is located below the air cylinder 3. The position detection mechanism 8 is mainly used to detect whether the position of the pipe column between the two clamping pliers 2 is in place. If the position of the clamping pliers 2 is in place, the position sensor 11 in the position detection mechanism 8 will send a signal to the PLC controller, and at this time, the PLC controller will automatically control the operation of the air cylinder 3.
[0026] Further, as a preferred embodiment, the position detection mechanism 8 includes a pulley 9, a support plate 10, a position sensor 11, a guide rail 12 and a slider 13. A guide rail 12 is arranged inside the clamp seat 1. The support plate 10 is installed on the guide rail 12 through the slider 13. One end of the support plate 10 extends out of the clamp seat 1 and is installed with a pulley 9. A position sensor 11 is arranged on one side of the guide rail 12, and the other end of the support plate 10 can contact the position sensor 11. Among them, see Figure 3As shown in the figure, it further includes a mounting plate 16, and the guide rail 12 and the position sensor 11 are both arranged on the mounting plate 16. The mounting plate 16 is fixed inside the clamp seat 1 by bolts. When the pipe column contacts the pulley 9, the pulley 9 will squeeze the support plate 10, causing the support plate 10 to move on the guide rail 12. Then, the other end of the support plate 10 will approach the position sensor 11. When it contacts the position sensor 11, it indicates that the position of the pipe column has moved in place at this time.
[0027] Among them, it further includes two tension springs 14, which are distributed on both sides of the guide rail 12. One end of the tension spring 14 is connected to the mounting plate 16 through a base 15, and the other end of the tension spring 14 is connected to the outer wall of the other end of the support plate 10. The provided tension springs 14 are mainly used for the automatic reset of the support plate 10. When the pipe column leaves the pulley 9, the support plate 10 can automatically return to the original position under the action of the tension springs 14.
[0028] The above are only the preferred embodiments of the present invention, and do not limit the implementation manners and protection scope of the present invention. For those skilled in the art, it should be realized that all the equivalent replacements and obvious changes made by using the description and illustrations of the present invention should be included in the protection scope of the present invention.
