Description

Technical Field

[0001] The invention belongs to the technical field of catheter positioning and assembly, and particularly relates to a catheter assembly and positioning device. Background Art

[0002] During the assembly of the catheter, the nut needs to be implanted in different installation positions on the catheter. In the prior art, the catheter is usually clamped and fixed by a clamp, and then the nut is manually picked up to install the nut inside the catheter. However, since there is more than one installation position on the catheter, and the angles of different installation positions are different, in actual operation, the catheter needs to be frequently removed from the clamp, rotated to a certain angle, and then re-clamped. In the process of frequently taking and placing the catheter and manually picking up the nut, it is very easy to cause alignment errors between the catheter and the nut, which in turn leads to poor nut installation quality or even unsuccessful nut installation.

[0003] Therefore, in order to solve the problem of excessive alignment error in the process of aligning a nut with multiple installation positions on a catheter in the prior art, the present invention discloses a catheter assembly positioning device. Summary of the Invention

[0004] The present invention discloses a catheter assembly positioning device, which can firmly clamp a nut and a catheter respectively to prevent the nut and the catheter from moving during the assembly process. At the same time, it can rotate the catheter while clamping the catheter so that different installation positions on the catheter are aligned with the nut, thereby ensuring that the positioning error of the nut meets the standard when it is assembled in the catheter.

[0005] The present invention is achieved through the following technical solutions: A catheter assembly and positioning device comprises a workbench, on which a rotating shaft is rotatably arranged, a first end of the rotating shaft being connected to an angle deflection device that drives the rotating shaft to rotate, and a second end of the rotating shaft being connected to a catheter clamping device; a linear moving device is arranged above the top of the workbench, a lifting device is arranged on the moving end of the linear moving device, and a nut clamping device is arranged on the lifting end of the lifting device.

[0006] The nut is clamped and fixed by the nut clamping device, while the catheter is clamped by the catheter clamping device. The linear motion device drives the nut to move linearly relative to the catheter, aligning the catheter's assembly position with the nut. The lifting device then lowers the nut toward the catheter and installs it in the catheter. The lifting device then retracts, re-clamping the nut by the nut clamping device. Simultaneously, the angle deflection device rotates the shaft and catheter clamping device, aligning the nut with another assembly position on the catheter. Repeating the above steps allows for quick installation of the nut at another angled assembly position on the catheter.

[0007] In order to better realize the present invention, further, the angle deflection device includes a gear, a rack, and an electric push rod. The gear is mounted on the first end of the rotating shaft. A rack is slidingly provided at the bottom of the gear. The rack is meshed with the gear, and an electric push rod is provided at one end of the rack.

[0008] In order to better implement the present invention, further, hinged seats are provided at both ends of the top of the workbench, and a rotating shaft is provided between the hinged seats at both ends; a fixed plate is provided on one side of the bottom of the hinged seat at either end, and a first sliding groove is formed between the fixed plate and the edge of the workbench, and the rack is slidingly fitted inside the first sliding groove.

[0009] In order to better realize the present invention, further, the catheter clamping device includes a base, a slide rail, a skateboard, a splint, and a splint driving device. The base is connected to the second end of the rotating shaft, and a slide rail is provided inside the base. Two groups of skateboards are slidingly provided on the slide rail. A splint is provided on one side of the skateboard. The skateboard is connected to the splint driving device, and the splint driving device is used to drive the two groups of skateboards to move toward each other or away from each other synchronously.

[0010] In order to better realize the present invention, further, the splint driving device includes a first screw rod, a first nut, and a first motor. The first screw rod is rotatably arranged inside the base, two sets of first nuts are mounted on the outside of the first screw rod, and a slide is connected to the outside of the first nut. One end of the first screw rod is connected to the output end of the first motor.

[0011] In order to better realize the present invention, further, the linear moving device includes a horizontal plate, a connecting plate, a third screw rod, a third nut, and a third motor. The interior of the horizontal plate is provided with a third slide groove, the interior of the third slide groove is provided with a third screw rod for rotation, the outside of the third screw rod is sleeved with a third nut, the outside of the third nut is installed with a connecting plate, the connecting plate is slidably connected to the third slide groove, and one end of the third screw rod is connected to the output end of the third motor.

[0012] In order to better implement the present invention, further, main body brackets are provided at both ends of the top of the workbench, and a horizontal plate is provided between the main body brackets at both ends.

[0013] In order to better realize the present invention, further, the nut clamping device includes a top plate, a limit plate, a second screw rod, a second nut, and a second motor.

A cylinder is provided on the top of the stand, and the push rod end of the cylinder is connected to the nut clamping device.

[0015] In order to better implement the present invention, further, a switch panel is provided on the front panel of the workbench.

[0016] Compared with the prior art, the present invention has the following advantages and beneficial effects: The present invention firmly clamps and fixes the catheter through the catheter clamping device, and clamps and fixes the nut through the nut clamping device, thereby avoiding the relative movement of the catheter and the nut during the assembly process; at the same time, the linear movement device drives the nut to move linearly relative to the catheter, and the angle deflection device drives the catheter to deflect the movement angle relative to the nut, so that the installation positions of different angles on the catheter can be aligned with the nut, and the lifting device drives the nut to rise and fall to complete the quick installation of the nut inside the catheter, and at the same time can effectively avoid the excessive positioning error between the nut and the catheter, thereby ensuring the installation position accuracy of the nut inside the catheter.
