Description
TECHNICAL FIELD

[0002] In the medical instrument manufacturing field, the welding quality of medical instrument parts is crucial, which is directly related to the performance and safety of medical instruments. In the traditional medical instrument part welding process, there are often many problems.
[0003] In the positioning aspect, the past often adopts the manual positioning mode, places the parts to be welded on the workbench, and adjusts the position by relying on the experience and naked eye observation of workers. This mode has low positioning accuracy and is difficult to ensure that the position of the parts is completely consistent every time welding. For some medical instruments with very high welding precision requirements, such as heart stents, precision surgical instruments, etc., welding defects are easily caused by position deviation, affecting product quality, and even causing product scrap, increasing production cost.
[0004] In the clamping link of the parts, the past often uses simple clamps, which have poor universality and are difficult to adapt to medical instrument parts of various shapes and sizes. Moreover, these clamps have insufficient clamping stability, and the parts are easily displaced due to welding thermal stress, mechanical vibration and other factors during the welding process, resulting in inaccurate welding position, reducing welding quality, and in severe cases, re-welding is required, further reducing production efficiency.
[0005] In addition, the butt joint process of the parts in the traditional welding operation is also relatively cumbersome. Due to the lack of effective transmission and guide mechanism, manual adjustment is required multiple times during the butt joint process, which not only consumes time and effort, but also makes it difficult to achieve precise butt joint, and cannot meet the needs of modern medical instrument production for efficient and high-precision welding.

[0032] Referring to the drawings Figs. 1-5 A medical instrument part welding positioning device, comprising a workbench 2 arranged below a welding gun 1, two positioning assemblies 3 are symmetrically arranged on the workbench 2, the positioning assembly 3 comprises a docking mechanism 4 and a clamping mechanism 5, the docking mechanism 4 is arranged on the workbench 2, the clamping mechanism 5 is arranged at the output end of the docking mechanism 4, the clamping mechanism 5 is used for clamping and fixing the medical instrument 6 to be welded, and the docking mechanism 4 is used for docking the medical instrument 6.
[0033] The docking mechanism 4 comprises a moving plate 41 and a mounting plate 42 arranged in parallel, the mounting plate 42 is arranged on the workbench 2, a screw rod 43 is rotatably arranged on the mounting plate 42, a threaded block 44 is threadedly arranged on the screw rod 43, the threaded block 44 is connected with the moving plate 41, the clamping mechanism 5 is arranged on the moving plate 41, and the screw rod 43 is connected with a motor 45. Two guide rails 47 are arranged in parallel on the mounting plate 42, the two guide rails 47 are arranged on the two sides of the screw rod 43 respectively, and two sliding blocks 46 are arranged below the moving plate 41 and are slidably arranged on the guide rails 47.
[0034] The clamping mechanism 5 comprises a mounting frame 51, a cylinder 52 is arranged at the bottom of the mounting frame 51, a mounting seat 53 is arranged on the piston rod of the cylinder 52, two first connecting rods 54 are rotatably arranged on the mounting seat 53 and are symmetrically arranged, two L-shaped connecting rods 56 are rotatably arranged on the mounting frame 51 and are symmetrically arranged, one end of the L-shaped connecting rod 56 is rotatably connected with the first connecting rod 54, and a clamping block 57 is arranged on the other end of the L-shaped connecting rod 56. A clamping groove 58 is arranged on the clamping block 57, and the clamping groove 58 is V-shaped. The mounting seat 53 and the first connecting rod 54 are rotatably connected through a pin shaft 55, a guide groove 59 is arranged on the mounting frame 51, one end of the pin shaft 55 protrudes from the first connecting rod 54, and the pin shaft 55 is slidably arranged in the guide groove 59.
[0035] Working principle: the medical device 6 to be welded is placed near the clamping block 57 of the clamping mechanism 5. The cylinder 52 is started, the piston rod of the cylinder 52 is extended, the mounting seat 53 is driven to move upwards. The mounting seat 53 is connected with the first connecting rod 54 through the pin shaft 55, since the pin shaft 55 slides up and down in the guide groove 59 of the mounting frame 51, as the mounting seat 53 rises, the first connecting rod 54 rotates around the rotation point of the mounting seat 53.
