Description

Technical Field

[0001] This utility model relates to the field of punching machine technology, and specifically to a punching machine that facilitates positioning. Background Technology

[0002] A catheter punching machine is an automated or semi-automated production line specifically designed to precisely punch drainage holes into the walls of silicone or rubber catheters. Utilizing precisely designed stamping dies and a power system (such as pneumatic or servo drive), it quickly and accurately punches side holes of the required shape (e.g., elliptical, circular) and size at specific locations on the catheter body, ensuring smooth, burr-free hole edges. This meets the hygiene standards and production efficiency requirements of medical devices and is one of the key pieces of equipment in the catheter manufacturing process.

[0003] Chinese utility model patent CN221089301 U discloses a catheter punching device, which includes "a workbench, a support, a punching assembly, a clamping assembly, and a positioning sleeve; one end of the positioning sleeve is fixedly installed on the upper surface of the workbench, and the catheter is fitted onto the positioning sleeve; the positioning sleeve has a through hole; the output end of the punching assembly cooperates with the through hole on the positioning sleeve to punch a hole; the output end of the clamping assembly cooperates with the positioning sleeve to clamp the catheter". However, in this device, the user needs to manually fit the catheter onto the outer surface of the positioning sleeve. Since catheters are mostly made of rubber, the catheter is easily stretched during the fitting process, causing deviation in the punching position and easily damaging the catheter. Utility Model Content

[0004] The purpose of this invention is to provide a punching machine that facilitates positioning, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a punching machine for easy positioning, comprising an outer frame, a punching assembly on the upper part of the outer frame, and a positioning assembly on the lower part of the punching assembly; the outer frame includes a worktable, and a lower clamp is fixedly installed on the upper end of the worktable; the punching assembly includes a lower pressure plate, and an upper clamp is provided on the lower end of the lower pressure plate; the lower pressure plate and the upper clamp are connected by two connecting rods, and the upper end of the connecting rods is provided with a bolt head for positioning; each connecting rod has a spring on its outer surface; a plurality of punching needles are fixedly installed on the lower end of the lower pressure plate; a plurality of reserved punching holes are opened inside the upper clamp, and the punching needles are perpendicularly corresponding to the reserved punching holes.

[0006] The beneficial effects of this utility model are as follows: by starting the hydraulic oil pump, the lower pressure plate is driven to press down, so that the upper clamp is pressed on top of the lower clamp. Then, the servo motor is started, which drives the transmission rod to rotate, thereby driving the two sliding brackets that mesh with the gear to move towards the center and pass between the lower clamp and the upper clamp. This achieves the effect of limiting and fixing the catheter between the lower clamp and the upper clamp when the device is in use, which facilitates the subsequent punching work, improves the punching yield of the device, and improves the practicality of the device.

[0007] To achieve the limiting of the sliding bracket:

[0008] The following configuration is further provided: a mounting bracket is fixedly installed at the upper end of the outer frame, and two slide rails are provided inside the workbench.

[0009] By adopting the above technical solution, the slider slides inside the slide rail, which limits the movement trajectory of the sliding support and facilitates the subsequent positioning of the catheter.

[0010] To provide downward pressure to the lower pressure plate:

[0011] The following configuration is further provided: a piston rod is fixedly installed at the upper end of the lower pressure plate, a hydraulic cylinder is slidably installed at the upper end of the piston rod, a hydraulic oil pump is connected to the upper end of the hydraulic cylinder via an oil pipe, and the hydraulic oil pump is installed at the upper end of the slide rail.

[0012] By adopting the above technical solution, the hydraulic oil pump is started, and the hydraulic oil enters the hydraulic cylinder through the oil pipe, which in turn pushes the piston rod down, and finally presses the upper clamp down.

[0013] To achieve precise punching:

[0014] The limiting component is further configured such that: the limiting component includes two sliding brackets, each of which has an air shaft rotatably mounted on its upper end, and each of the air shafts has a slider fixedly mounted on its upper end.

[0015] By adopting the above technical solution, the diameter of the air shaft is smaller than that of the catheter, making it easier to insert. Then, air is injected into the air shaft to support the catheter, which facilitates the subsequent punching work and prevents the catheter from being flattened by the punching needle, causing the punching position to deviate.

[0016] To achieve synchronous movement of the sliding supports on both sides:

[0017] Further configuration: the inner side of each sliding bracket is provided with several toothed grooves, the two sliding brackets are meshed with the same gear, the lower end of the gear is fixedly installed with a transmission rod, the lower end of the transmission rod is rotatably installed with a servo motor, and the servo motor is installed to the bottom of the worktable by bolts.

[0018] By adopting the above technical solution, the servo motor is started, which drives the transmission rod and gear to rotate. Since one gear meshes with the sliding brackets on both sides at the same time, it drives the two sliding brackets to move synchronously.

[0019] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0025] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0026] Please see Figures 1 to 4 A punching machine for easy positioning includes an outer frame 1, a punching assembly 2 on the upper part of the outer frame 1, and a limiting assembly 3 on the lower part of the punching assembly 2. The outer frame 1 includes a worktable 11, and a lower clamp 12 is fixedly installed on the upper end of the worktable 11. The punching assembly 2 includes a lower pressure plate 21, and an upper clamp 22 is provided on the lower end of the lower pressure plate 21. The lower pressure plate 21 and the upper clamp 22 are connected by two connecting rods 23. The upper end of the connecting rods 23 is provided with a bolt head for limiting. A spring 24 is provided on the outer surface of each connecting rod 23. Several punching needles 25 are fixedly installed on the lower end of the lower pressure plate 21. Several reserved punch holes 26 are opened inside the upper clamp 22, and the punching needles 25 are perpendicularly corresponding to the reserved punch holes 26.

[0027] In this embodiment, as Figure 1 and Figure 2As shown, a mounting bracket 13 is fixedly installed at the upper end of the outer frame 1, and two slide rails 14 are opened inside the worktable 11.

[0028] In this embodiment, as Figure 1 and Figure 3 As shown, a piston rod 27 is fixedly installed at the upper end of the lower pressure plate 21, and a hydraulic cylinder 28 is slidably installed at the upper end of the piston rod 27. A hydraulic oil pump 29 is connected to the upper end of the hydraulic cylinder 28 through an oil pipe, and the hydraulic oil pump 29 is installed at the upper end of the slide rail 14.

[0029] In this embodiment, as Figure 1 and Figure 4 As shown, the limiting component 3 includes two sliding brackets 31, each of which has an air shaft 32 rotatably mounted on its upper end, and each of the air shafts 32 has a slider 37 fixedly mounted on its upper end.

[0030] In this embodiment, as Figure 1 and Figure 4 As shown, the inner side of each sliding bracket 31 is provided with several toothed grooves 33, and the same gear 34 meshes between two sliding brackets 31. A transmission rod 35 is fixedly installed at the lower end of the gear 34, and a servo motor 36 is rotatably installed at the lower end of the transmission rod 35. The servo motor 36 is installed to the bottom of the worktable 11 by bolts.

[0031] The working process of this punching machine, which facilitates positioning, is as follows:

[0032] First, the user places the catheter in the groove of the lower clamp 12. Then, the hydraulic pump 29 (model: S1 P10) is activated to inject hydraulic oil into the stamping assembly 2, which pushes the piston rod 27 downward, causing the lower pressure plate 21 and the upper clamp 22 to move downward. When the upper clamp 22 presses down on the lower clamp 12, the servo motor 36 (model: SGM7J-01AFC6S) is activated, driving the transmission rod 35 and gear 34 to rotate. This causes the sliding supports 31 on both sides and the air shaft 32 to move towards the center, so that the air shafts 32 on both sides are inserted into the catheter. The catheter is inflated internally to support and fix its internal structure. Then, the lower pressure plate 21 continues to press down, compressing the pre-drilled hole 26. The punching needle 25 presses down through the pre-drilled hole 26 to punch the catheter. If different angles of the catheter need to be punched, simply rotate the air shaft 32. When the punching is complete, the upper clamp 22 rises to release the gas inside the air shaft 32. The servo motor 36 reverses, and the sliding brackets 31 on both sides drive the air shaft 32 to be pulled outward. Then, the punched catheter can be taken out.
