[0002] Medical instruments refer to instruments, equipment, appliances, in-vitro diagnostic reagents and calibrators, materials and other similar or related articles, including computer software required, which are directly or indirectly used for human bodies. Medical instruments include medical devices and medical consumables. The main effect is obtained through physical means, not through pharmacology, immunology or metabolism, or although these means are involved, only play a supporting role.

[0003] In the processing of medical instruments made of metal materials, some instruments need to be cut and welded, such as surgical scissors, hemostatic forceps, etc. When processing surgical scissors, the blade part of the scissors needs to be cut, and the handle and the blade part need to be welded. During processing, after one process is completed, it is manually transferred to the next process. Due to subjective reasons of workers, the required time will have efficiency deviation.

[0004] Therefore, we propose a cutting and welding device for medical instrument metal part processing to solve the above problems. SUMMARY

[0010] Further, the switching mechanism comprises a motor, a transmission mechanism, a sliding table and a lifting table, the motor is fixedly installed on the processing table, the sliding table is slidably installed on the transmission mechanism, and the lifting table is liftably installed on the transmission mechanism.

[0011] Further, the transmission mechanism comprises a screw rod, a screw rod base, an extension piece installed on the base plate, a protrusion and the base plate, the extension piece is fixedly connected with the lifting platform, the protrusion is fixedly installed on the base plate, the screw rod is connected with the output end of the motor through a shaft coupling, the screw rod base is threadedly installed on the screw rod, a strip-shaped groove for linear sliding of the screw rod base is formed in the base plate, the sliding table is fixedly installed on the screw rod base, the protrusion is fixedly installed on the sliding table, and the bottom of the lifting platform is rotatably installed with a bearing capable of contacting the protrusion.

[0012] Further, the top surface of the protrusion is in a trapezoidal shape.

[0013] When the bearing contacts the protrusion and rolls along the slope surface of the protrusion to frictionally climb the slope, the lifting platform is lifted.

[0014] When the bearing contacts the protrusion and rolls along the slope surface of the protrusion to frictionally descend the slope, the lifting platform is lowered.

[0015] Further, the extension piece comprises a fixed pipe and a telescopic rod, one end of the telescopic rod is slidably installed in the fixed pipe, the fixed pipe is fixedly installed on the base plate, and one end of the telescopic rod is fixedly connected with the bottom of the lifting platform.

[0016] Further, a limiting piece is fixedly installed on the processing table, the limiting piece comprises a support and a rubber pad, the support is fixedly installed on the processing table, the rubber pad is fixedly installed on the support, and the rubber pad can abut against the upper part of the lifting platform.

[0023] 2. Through the cooperation of the motor and the transmission mechanism, when the motor is working, it drives the sliding table to reciprocate. At the same time as the sliding table reciprocates, it can drive the lifting platform to move up and down, thereby enabling the welding or cutting body to operate or shut down. The metal parts on the sliding table are cut and welded. The cutting and welding process is completed by reciprocating motion, which can effectively reduce the transfer process, reduce manual operation, and improve work efficiency.

[0024] 3. During cutting or welding, the exhaust fan operates, generating suction from the dust nozzle. The dust nozzle draws dust into the exhaust pipe. Due to the spiral shape of the exhaust pipe, the dust's kinetic energy is reduced when the airflow collides with the baffles, and the dust is trapped by the filter, reducing dust emissions and improving the air quality of the working environment.

DETAILED DESCRIPTION

[0040] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the technical scheme in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0041] Referring to Figures 1-12 , the embodiments of the present application provide a cutting and welding device for processing metal parts of medical devices, which comprises a processing table 1, a welding main body 2 and a cutting main body 3. The welding main body 2 and the cutting main body 3 are both installed on the processing table 1. The welding main body 2 is used for welding metal parts, and the cutting main body 3 is used for cutting metal parts.

[0042] The processing table 1 is provided with a switching mechanism 4 for switching the welding body 2 and the cutting body 3.

[0043] It should be noted that the cutting body 3 uses laser to cut metal parts;

[0044] The welding of the metal part, the cutting process is not in the order.

[0045] By using the switching mechanism 4, the welding process and the cutting process can be switched during the conveying of the metal part during the cutting or welding operation of the metal part, which can effectively reduce the time spent by manual process conversion and improve the processing efficiency.

[0046] In this embodiment, the switching mechanism 4 includes a motor 5, a transmission mechanism, a sliding table 7 and a lifting table 8, the motor 5 is fixedly installed on the processing table 1, the sliding table 7 is slidably installed on the transmission mechanism, and the lifting table 8 is installed on the transmission mechanism.

[0047] It should be noted that the lifting table 8 is provided with two, respectively used for installing the welding body 2 and the cutting body 3;

[0048] The sliding table 7 is provided with a clamping mechanism for fixing the metal part of the medical instrument.

[0049] Referring to Figure 2 , Figure 3 and Figure 4 , specifically, the bracket 19 is fixedly installed with a press switch 29 for controlling the operation of the welding body 2 and the cutting body 3.

[0050] It should be noted that when the lifting table 8 is lifted to the highest position and contacts the press switch 29, the welding body 2 and the cutting body 3 are opened.

[0051] By using the above scheme, the motor 5 and the transmission mechanism are matched, when the motor 5 works, the sliding table 7 reciprocates, and the lifting table 8 moves up and down at the same time, so that the welding body 2 or the cutting body 3 operates or closes, and the welding and cutting operation of the metal part is carried out.

[0052] Referring to Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 11In the embodiment, the transmission mechanism comprises a screw rod 9, a screw rod base 10, an extension piece 11 fixedly connected with the lifting platform 8, a protruding block 12 fixedly installed on the cushion plate 13, and the cushion plate 13. The screw rod 9 is connected with the output end of the motor 5 through a shaft coupling. The screw rod base 10 is threadedly installed on the screw rod 9. The cushion plate 13 is provided with a strip-shaped groove 14 for linear sliding of the screw rod base 10. The sliding platform 7 is fixedly installed on the screw rod base 10. The protruding block 12 is fixedly installed on the sliding platform 7. The bottom of the lifting platform 8 is rotatably installed with a bearing 15 capable of contacting the protruding block 12.

[0053] It should be noted that when the bearing 15 is above the sliding platform 7, there is a 1mm gap between the bearing 15 and the sliding platform 7, which can avoid collision between the sliding platform 7 and the bearing 15.

[0054] A through hole is formed in the tabletop of the processing platform 1 and communicates with the strip-shaped groove 14.

[0055] Referring to Figure 9 and Figure 10 , specifically, the cushion plate 13 is fixedly installed with a guide rail 25. The bottom of the sliding platform 7 is fixedly installed with a guide block 26 in sliding cooperation with the guide rail 25.

[0056] It should be noted that the guide rail 25 and the guide block 26 can limit the moving direction of the sliding platform 7, which can reduce the working load of the screw rod base 10.

[0057] Specifically, the tabletop of the protruding block 12 is set as a trapezoidal table.

[0058] When the bearing 15 contacts the protruding block 12 and the bearing 15 rolls and rubs along the slope surface of the protruding block 12 to go uphill, the lifting platform 8 is raised.

[0059] When the bearing 15 contacts the protruding block 12 and the bearing 15 rolls and rubs along the slope surface of the protruding block 12 to go downhill, the lifting platform 8 is lowered.

[0060] It should be noted that the protruding block 12 is provided with two groups, and the two groups of protruding blocks 12 are arranged in a staggered manner. The bearing 15 and the protruding block 12 are arranged in the same manner.

[0061] When the bearing 15 contacts the protruding block 12, the extension rod 17 moves up and down along the lumen of the fixed tube 16, so that the protruding block 12 provides an upward thrust to the lifting platform 8 when the bearing 15 contacts the slope surface of the protruding block 12. When going downhill, the lifting platform 8 relies on its own gravity to descend and reset, so as to release the pressing relationship with the pressing switch 29, thereby closing the welding body 2 or the cutting body 3.

[0062] Referring to Figure 4 , Figure 5 andFigure 6 Specifically, the telescopic part 11 comprises a fixed tube 16 and a telescopic rod 17, one end of the telescopic rod 17 is slidingly installed in the fixed tube 16, the fixed tube 16 is fixedly installed on the base plate 13, and one end of the telescopic rod 17 is fixedly connected with the bottom of the lifting platform 8.

[0063] It should be noted that the telescopic rod 17 is in gap sliding fit with the fixed tube 16, the gap is set to 0.01mm, the telescopic rod 17 can move up and down along the lumen of the fixed tube 16, and the moving direction of the lifting platform 8 can be limited.

[0064] With the above scheme, when the motor 5 works, it drives the screw rod 9 to rotate, converts the circular motion of the screw rod 9 into the linear motion of the screw rod seat along the strip-shaped groove 14, thereby driving the sliding table 7 to move linearly. In the moving process of the sliding table 7, the protrusion 12 is pressed against the bearing 15, the fixed tube 16 and the telescopic rod 17 limit the upward movement of the lifting platform 8 along the lifting direction of the telescopic rod 17, thereby making the lifting platform 8 contact the press switch 29, turning on the cutting main body 3 or the welding main body 2, and welding or cutting the metal piece. The process switching can be quickly performed, the manual operation can be effectively reduced, the transfer process can be omitted, and the processing efficiency can be improved.

[0065] In this embodiment, a limiting part 18 is fixedly installed on the processing table 1, the limiting part 18 comprises a bracket 19 and a rubber pad 20, the bracket 19 is fixedly installed on the processing table 1, and the rubber pad 20 is fixedly installed on the bracket 19. The rubber pad 20 can abut against the upper part of the lifting platform 8.

[0066] It should be noted that when the sliding table 7 moves to the two ends of the strip-shaped groove 14, the sliding table 7 is out of the coverage range of the bracket 19, and the feeding and discharging operations can be performed to take down the metal piece on the sliding table 7 or load the metal piece on the clamping mechanism.

[0067] With the above scheme, by using the limiting part 18, when the lifting platform 8 is raised, the lifting platform 8 abuts against the rubber pad 20, the position where the lifting platform 8 is raised to the highest point is pressed and fixed, and buffering is provided, thereby effectively ensuring the stability of the lifting platform 8 during cutting or welding.

[0068] In this embodiment, a dust suction nozzle 21 for sucking the smoke and dust generated during cutting and welding is fixedly installed on the sliding table 7, an air exhaust fan 22 is communicated with the air outlet end of the dust suction nozzle 21, a dust discharge pipe 23 is communicated with one end of the air exhaust fan 22, and a water tank 24 is communicated with the air outlet end of the dust discharge pipe 23.

[0069] It should be noted that the air guide pipe communicated between the dust suction nozzle 21 and the air exhaust fan 22 is set as a redundant pipe.

[0070] Referring to Figure 1 , Figure 2 and Figure 12 , in particular, the dust removal pipe 23 is provided as a spiral pipe, a filter 27 is fixedly installed on the dust removal pipe 23, and a baffle 28 for colliding with the airflow is arranged in the dust removal pipe 23.

[0071] It should be noted that the filter 27 is provided as a Y-shaped filter.

[0072] With the above scheme, during cutting or welding, the exhaust fan 22 works to generate suction force of the dust suction nozzle 21, and the dust suction nozzle 21 sucks dust into the dust removal pipe 23. Due to the spiral characteristic of the dust removal pipe 23, when the airflow collides with the baffle 28, the kinetic energy of the dust is reduced, and the dust is trapped by the filter 27, thereby reducing dust discharge and improving air quality of the working environment.

[0073] The above embodiment has the following beneficial effects:

[0074] By using the switching mechanism 4, when the metal piece is cut or welded, the welding process and the cutting process can be switched during the conveying of the metal piece, the time spent by manual process switching can be effectively reduced, and the processing efficiency can be effectively improved.

[0075] By cooperating the motor 5 with the transmission mechanism, when the motor 5 works, the sliding table 7 reciprocates, and the lifting table 8 moves up and down at the same time, so that the welding main body 2 or the cutting main body 3 operates or closes, and the welding and cutting operations of the metal piece are performed. When moving to the cutting position, the device is opened, and when leaving, the device is closed, which can effectively save resources and has a simple structure and convenient operation.

[0076] When the motor 5 works, the lead screw 9 rotates to convert the circular motion of the lead screw 9 into the linear motion of the screw seat along the strip-shaped groove 14, thereby driving the sliding table 7 to move linearly. During the movement of the sliding table 7, the protrusion 12 presses the bearing 15, and the fixed pipe 16 and the extension rod 17 are limited in position, so that the lifting table 8 moves upward along the extension rod 17 in the lifting direction, thereby making the lifting table 8 contact with the pressing switch 29 to open the cutting main body 3 or the welding main body 2, and the metal piece is welded or cut. The process switching can be quickly performed, the manual operation can be effectively reduced, the transfer process can be omitted, and the processing efficiency can be improved.

[0077] By using the limiting piece 18, when the lifting table 8 is raised, the lifting table 8 is in contact with the rubber pad 20 to press and fix the position of the lifting table 8 when it is raised to the highest point, and provide buffering, which can effectively ensure the stability of the lifting table 8 during cutting or welding.

[0078] When cutting or welding, the suction fan 22 works, so that the dust suction nozzle 21 generates suction force, and the dust suction nozzle 21 sucks dust into the dust exhaust pipe 23. Due to the spiral characteristics of the dust exhaust pipe 23, when the airflow collides with the baffle 28, the kinetic energy of the dust is reduced, and the dust is intercepted by the filter 27, so that the dust exhaust is reduced, and the air quality of the working environment is improved.

[0079] Although the present application has been described in detail with reference to the foregoing embodiments, it should be understood that the technical solutions recorded in the foregoing embodiments can still be modified, or some technical features can be replaced by equivalents, without departing from the spirit and scope of the technical solutions of the embodiments of the present application.
