[0035] See also Figure 1-Figure 2 , and combined with Figure 3-Figure 7 The punching positioning device in the present application is mainly used in the punching process of medical device tube assemblies. Specifically, the tube assembly is installed on a slider that can be telescopically moved forward and backward, and the slider is driven by the connection of the telescopic rod to move the tube assembly in the same straight line in its axial direction. By controlling the telescopic amount of the telescopic rod, the spacing between different hole positions is controlled to be the same, and it is ensured that all the hole positions are respectively on the same straight line in the axial direction of the tube assembly, thereby improving the accuracy of the punching operation.

[0036] The punching and positioning device specifically comprises a telescopic mechanism 1 and a displacement mechanism 2, the pipe assembly is placed on the displacement mechanism 2, and a punching machine performs a punching operation on the displacement mechanism 2.

[0037] The telescopic mechanism 1 is mainly used to control the forward and backward telescopic movement of the displacement mechanism 2. The telescopic mechanism 1 can drive the displacement mechanism 2 and the pipe assembly loaded by the displacement mechanism 2 to move forward and backward to control and adjust the punching position of the pipe assembly.

[0038] Specifically, the telescopic mechanism 1 includes a telescopic rod, the displacement mechanism 2 includes a slider 22, the pipe assembly is specifically placed and installed on the slider 22, the telescopic rod is connected to the slider 22, and can drive the slider 22 to telescope back and forth, thereby enabling the telescopic rod to drive the slider 22 and the pipe assembly to telescope back and forth, thereby controlling the punching position of the pipe assembly.

[0039] The punching operation is specifically performed by a punching machine, and the slider 22 is arranged in the punching area of ​​the punching machine. The slider 22 and the pipe assembly can be telescopically moved forward and backward at the punching station of the punching machine.

[0040] Through the punching positioning device in the utility model, the telescopic direction and telescopic movement stroke of the slider 22 and the pipe assembly can be accurately controlled, meeting the technical requirements for controlling the hole spacing and distributing multiple holes on the same straight line in the axial direction of the pipe assembly.

[0041] In one specific embodiment, the telescopic mechanism 1 includes a fixedly installed cylinder 11, a piston 12 is arranged inside the cylinder 11, and the telescopic rod is specifically a piston rod 13 connected to the piston 12. The piston 12 moves back and forth in the cylinder 11, driving the telescopic rod in the form of the piston rod 13 to move back and forth relative to the cylinder 11.

[0042] The forward and backward movement of the piston 12 in the cylinder 11 is specifically achieved by controlling the air pressure on the left and right sides of the piston 12 inside the cylinder 11. Furthermore, two air guide ports 14 are provided on the cylinder 11, and the air guide ports 14 specifically switch back and forth between the states of an air inlet and an air outlet.

[0043] Preferably, the two air guide ports 14 are respectively arranged on both sides of the piston 12 and are respectively communicated with the internal space of the cylinder 11 . The piston 12 specifically divides the interior of the cylinder 11 into two chambers.

[0044] When it is necessary to control the piston rod 13 to extend, combined with the structure in the accompanying drawings, the air inlet 14 on the left is allowed to intake air, and the external air supply enters the chamber on the left side of the piston 12 through the air inlet on the left, and the air pressure in the chamber on the left side increases. The air inlet 14 on the right side is in the form of an air outlet, and the air pressure in the chamber on the right side of the piston 12 decreases, thereby pushing the piston 12 to move forward from left to right, and controlling the piston rod 13 to extend outward.

[0045] When it is necessary to control the piston rod 13 to retract, combined with the structure in the accompanying drawings, air is taken in through the air guide port 14 on the right, and the external air supply enters the chamber on the right side of the piston 12 through the transformed air inlet port on the right. The air pressure in the chamber on the right side increases, and the air guide port 14 on the left side is transformed into an air outlet. The air pressure in the chamber on the left side of the piston 12 decreases, thereby pushing the piston 12 to move from right to left and backward, and controlling the piston rod 13 to retract.

[0046] The piston 12 occupies the entire longitudinal section of the cylinder 11 , and can drive the piston rod 13 to move in the same straight line in the horizontal direction of the axial direction of the cylinder 11 during movement, thereby providing a guarantee for the stable sliding of the slider 22 .

[0047] Both air guide ports 14 are externally connected to air guide pipes, and air guide operations are performed through the air guide pipes during the air intake and air exhaust processes.

[0048] In another specific embodiment, the displacement mechanism 2 includes a base 21 , and a slider 22 is installed on the base 21 . Specifically, the base 21 is fixedly installed, and the slider 22 moves forward and backward relative to the base 21 .

[0049] The telescopic rod and the slider 22 are specifically in the form of a plug-in connection. The end of the telescopic rod is plugged into the slider 22. The slider 22 is provided with a plug-in hole 23 for installing the telescopic rod. The end of the telescopic rod and the hole wall of the plug-in hole 23 are respectively provided with matching threads, so that the telescopic rod and the slider 22 are detachably connected together.

[0050] Specifically, an external thread is provided at the end of the telescopic rod, and an internal thread is provided on the hole wall of the plug hole 23, and the telescopic rod and the slider 22 are assembled through thread matching.

[0051] It should be pointed out that, in addition to the form of the cylinder 11 and the piston rod 13, the telescopic mechanism 1 can also be set in the form of an electric push rod, so that the electric push rod is connected to the slider 22, and the forward and backward telescopic movement of the slider 22 is controlled by the forward and backward telescopic movement of the electric push rod, which can also achieve the above-mentioned technical purpose, and will not be repeated here.

[0052] The slider 22 slides relative to the base 21. Specifically, the slider 22 slides linearly relative to the length direction of the base 21. In order to ensure the reliability of the slider 22 sliding relative to the base 21, a dovetail-shaped limiting groove 24 is provided on the base 21. The limiting groove 24 includes a through groove that runs through the length direction of the base 21. In the figure, the limiting groove 24 is arranged on the top of the base 21.

[0053] A limiting protrusion 25 is provided on the side of the slider 22 opposite to the base 21. In the accompanying drawings, the limiting protrusion 25 is provided at the bottom of the slider 22. The shape of the limiting protrusion 25 is adapted to the shape of the limiting groove 24. By limiting the limiting protrusion 25 and installing it in the limiting groove 24 and maintaining a clearance fit between the two, the slider 22 can slide linearly on the base 21.

[0054] A mounting groove 26 for placing a pipe assembly is provided on the side of the slider 22 opposite to the base 21. In the drawings, the mounting groove 26 is provided on the top of the slider 22 and is mainly used for placing and installing the pipe assembly.

[0055] The mounting groove 26 is specifically an open groove structure, and a plurality of silicone pads 27 are arranged on the groove wall. By placing the pipe assembly on the silicone pads 27, the pipe assembly can be protected to prevent the pipe assembly from being scratched on the slider 22.

[0056] In order to fix the pipe assembly, a buckling cover plate 3 is provided on the slider 22 . After the pipe assembly is placed in the mounting groove 26 on the slider 22 , the pipe assembly can be buckled and fixed by the buckling cover plate 3 .

[0057] The pressing cover plate 3 is installed on the slider 22 by means of a hinge so as to be opened and closed, which can facilitate the taking and placing of the pipe assembly on the slider 22. In order to avoid the actuator of the punching machine, an avoidance notch 31 for avoiding the punching position is provided on the pressing cover plate 3, thereby facilitating the punching operation of the pipe assembly.

[0058] The utility model further comprises a base 4 , which is specifically an operating platform of the punching machine. The cylinder 11 and the base 21 are fixedly mounted on the base 4 , which can ensure the stability of the cylinder 11 and the base 21 .

[0059] Through the punching positioning device in the utility model, the moving stroke of the piston rod 13 can be adjusted by controlling the cylinder 11, so as to control and adjust the position of the punching. Compared with the existing manual punching adjustment, the hole position of the pipe assembly can be accurately controlled, and the linear distribution state of different hole positions in the axial direction of the pipe assembly can be ensured.

[0060] During use, the cylinder 11 is fixed on the operating platform of the punching machine, and the piston rod 13 is connected to the slider 22. The forward and backward movement of the cylinder 11 drives the slider 22 to move forward and backward. The limit of the movement distance of the cylinder 11 is set according to the hole spacing to ensure that the position of each hole is the same. The top surface of the slider 22 has a pipe assembly installation groove 26, and a silicone pad 27 is set in the groove. The pipe assembly to be punched is installed in the installation groove 26. The silicone pad 27 is soft and flexible to protect and fix the pipe assembly. Finally, the cylinder 11 moves forward to push the slider 22 forward, and the slider 22 moves forward to drive the displacement of the pre-punched pipe assembly, realizing automatic movement and automatic positioning of the hole position, so that the double hole spacing remains consistent and the double control level is consistent.

[0061] The utility model also provides a tube punching device, including the punching positioning device and the punching machine described above.
