The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0029] Example:

[0030] like Figure 2-5 As shown, this embodiment provides a medical knife bar assembly welding device, including a base 1, a lifting drive device 2, a support plate 3, a joint positioning plate 4, a knife bar supporting plate 5 and a slide assembly 6;

[0031] The slide assembly 6 is provided on the base 1, and the slide assembly 6 has a sliding end that can move relative to the base 1, the support plate 3 is provided on the sliding end, the joint positioning plate 4 is provided on the top of the support plate 3, and the lifting drive device 2 is provided on the side of the support plate 3;

[0032] The driving end of the lifting drive device 2 is connected to the tool bar support plate 5 and can act on the tool bar support plate 5 to move relative to the joint positioning plate 4. The tool bar support plate 5 is located below the joint positioning plate 4.

[0033] The joint positioning plate 4 is provided with a positioning portion for positioning the medical knife rod.

[0034] The purpose of the structure of this embodiment is to improve the problems of inaccurate workpiece positioning in the above-mentioned traditional welding method, one piece is assembled and welded each time, the workpiece fixture needs to be frequently adjusted, the production process is time-consuming and labor-intensive, and product quality is difficult to guarantee. A device is proposed that can process multiple sets of workpieces at the same time, has accurate positioning, simple assembly, easy unloading, and convenient laser welding, thereby solving the current situation of inaccurate positioning and low work efficiency of the traditional assembly welding method, and ensuring that the tool bar welding work can be completed efficiently and with high quality.

[0035] Its working principle is:

[0036] The positioning portion on the joint positioning plate 4 can position the medical knife bar. Specifically, the knife bar joint 10 and the knife bar body 11 cooperate with the positioning portion. The sliding end of the slide assembly 6 acts on the joint positioning plate 4 to move it to the bottom of the laser welder 12. The knife bar joint 10 and the knife bar body 11 are welded by the laser welder 12. After welding, the sliding end of the slide assembly 6 acts on the joint positioning plate 4 to move it out from the bottom position of the laser welder 12. Finally, the lifting drive device 2 acts on the knife bar support plate 5 to move it up. The knife bar support plate 5 acts on the knife bar body 11 and separates the knife bar body 11 and the knife bar joint 10 that have been welded into one from the joint positioning plate 4 and takes it out. Therefore, the knife bar joint 10 and the knife bar body 11 can be quickly and accurately positioned. The workpieces can be assembled and welded in batches in one operation, achieving the effect of simple loading and fast unloading, so that the product processing quality is guaranteed.

[0037] The specific structure of the slide assembly 6 of this embodiment is as follows:

[0038] It includes a slide mounting seat 601, a slide rail member 602 and a slide seat 603. The slide mounting seat 601 is fixed to the base 1. The slide rail member 602 is arranged on the slide mounting seat 601 along the length direction of the slide mounting seat 601. The slide seat 603 slides with the slide rail member 602, and the slide seat 603 is a sliding end.

[0039] Specifically, fixing bolts 604 are provided at both ends of the slide mounting seat 601 in the length direction, and threaded holes 605 that can cooperate with the fixing bolts 604 are provided on the slide seat 603 .

[0040] Specifically, it also includes a lower connecting plate 7 , the bottom of the support plate 3 is connected to the lower connecting plate 7 , and is connected to the sliding end of the slide assembly 6 through the lower connecting plate 7 .

[0041] Specifically, support columns 8 are provided between the joint positioning plate 4 and the lower connecting plate 7 , and the number of the support columns 8 is more than two and they are symmetrically arranged.

[0042] In the above structure, the slide seat 603 moves relative to the slide mounting seat 601 by sliding with the slide rail member 602. The structure of the slide rail member 602 can ensure the stability of the slide seat 603 during movement. At the same time, when the slide seat 603 moves to the two ends of the slide mounting seat 601 in the longitudinal direction, it can be connected with the fixing bolt member 604 to ensure the stability of the relative position of the slide seat 603 and the slide mounting seat 601, preventing shaking from affecting the execution of workpiece loading and assembly, workpiece unloading after welding, or workpiece laser welding. At the same time, the support column 8 is provided to ensure the stability of the overall structure.

[0043] In this embodiment, the support plate 3 is provided with a limiting hole 301. One end of the tool bar support plate 5 passes through the limiting hole 301, and the other end is connected to the driving end of the lifting drive device 2. The other end of the tool bar support plate 5 is provided with a limiting rib 501. The above structure of the limiting hole 301 and the limiting rib 501 limits the travel of the tool bar support plate 5, ensuring the stability of the overall structure and preventing the tool bar support plate 5 from contacting the support plate 3 due to travel overload, thereby causing structural damage.

[0044] The specific structure of the positioning portion for positioning the medical knife rod in this embodiment is as follows:

[0045] The positioning part includes a plurality of positioning hole assemblies, and the positioning hole assemblies include a first positioning hole 401 and a second positioning hole 402. The first positioning hole 401 is arranged above the second positioning hole 402, and the first positioning hole 401 and the second positioning hole 402 are coaxially arranged, wherein the cross-section of the first positioning hole 401 and the second positioning hole 402 is circular, and the first positioning hole 401 is a stepped hole structure, which can match the shape of the tool rod joint 10, and the second positioning hole 402 is for the tool rod body 11 to pass through. At the same time, the position of the tool rod support plate 5 is adjusted so that the tool rod support plate 5 contacts the bottom of the tool rod body 11. When the workpiece is unloaded after welding, the lifting drive device 2 drives the tool rod support plate 5 to move up 20 mm, the welded workpiece is lifted upward, and the tool rod joint 10 is separated from the joint positioning plate 4. At this time, the medical tool rod is taken out as a whole.

[0046] In order to facilitate the above-mentioned operation of removing the medical knife rod as a whole, this embodiment also includes a discharge plate 9, which includes a discharge portion 901 and a gripping portion 902. The discharge portion 901 is provided with a plurality of discharge grooves 9011, and the plurality of discharge grooves 9011 are arranged in parallel. The discharge grooves 9011 cooperate with the knife rod body 11, and at the same time, the end face of the discharge portion 901 abuts against the bottom of the knife rod joint 10. Moving the discharge plate 9 can facilitate the removal of the medical knife rod as a whole.

[0047] The lifting drive device 2 of this embodiment can be a lifting cylinder device.

[0048] In summary, the present invention has a reasonable structural design, a clear working principle, and is easy to operate. It can quickly and accurately position the shank joint 10 and the shank body 11, and can assemble and weld workpieces in batches in a single operation. This ensures simple loading and unloading, ensuring guaranteed product processing quality.

[0049] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Therefore, any modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
