[0038] 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; The sliding table 7 is provided with a clamping mechanism for fixing the metal piece of medical instrument.

[0039] 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.

[0040] 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.

[0041] With the above scheme, by cooperating the motor 5 with the transmission mechanism, when the motor 5 works, the sliding table 7 reciprocates, and at the same time, the lifting table 8 moves up and down, so that the welding body 2 or the cutting body 3 operates or closes, and the welding and cutting operations of the metal piece are carried out.

[0042] 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 lug 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 strip-shaped groove 14 for the linear sliding of the screw rod base 10 is formed on the cushion plate 13, the sliding platform 7 is fixedly installed on the screw rod base 10, the lug 12 is fixedly installed on the sliding platform 7, and the bottom of the lifting platform 8 is rotatably installed with the bearing 15 capable of contacting the lug 12.

[0043] It should be noted that when the bearing 15 is located above the sliding platform 7, there is a gap of 1mm between the bearing 15 and the sliding platform 7, so that the collision between the sliding platform 7 and the bearing 15 can be avoided. A through hole communicating with the strip-shaped groove 14 is formed on the tabletop of the processing platform 1.

[0044] Referring to Figure 9 and Figure 10 , specifically, the cushion plate 13 is fixedly installed with a guide rail 25, and the bottom of the sliding platform 7 is fixedly installed with a guide block 26 in sliding cooperation with the guide rail 25.

[0045] It should be noted that the guide rail 25 and the guide block 26 can limit the moving direction of the sliding platform 7, so that the working load of the screw rod base 10 can be reduced.

[0046] Specifically, the tabletop of the lug 12 is set as a trapezoidal table. When the bearing 15 contacts the lug 12 and the bearing 15 rolls and rubs along the slope surface of the lug 12 to go uphill, the lifting platform 8 is lifted. When the bearing 15 contacts the lug 12 and the bearing 15 rolls and rubs along the slope surface of the lug 12 to go downhill, the lifting platform 8 is lowered.

[0047] It should be noted that the lug 12 is provided with two groups, the two groups of lugs 12 are set in a staggered manner, and the bearing 15 is set in the same manner as the lug 12. When the bearing 15 contacts the lug 12, the lug 12 provides an upward thrust to the lifting platform 8 due to the up-and-down movement of the extension rod 17 along the lumen of the fixed tube 16 when the bearing 15 contacts the slope surface of the lug 12, and the lifting platform 8 is lowered and reset by its own gravity when going downhill, so as to be out of the pressing relationship with the pressing switch 29, thereby closing the welding body 2 or the cutting body 3.

[0048] Referring to Figure 4 , Figure 5 and Figure 6Specifically, 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.

[0050] 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 protruding block 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, and the cutting main body 3 or the welding main body 2 is opened, so that the metal piece can be 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.

[0051] In the embodiment, the machining table 1 is fixedly installed with a limiting part 18, the limiting part 18 comprises a support 19 and a rubber pad 20, the support 19 is fixedly installed on the machining table 1, and the rubber pad 20 is fixedly installed on the support 19, and the rubber pad 20 can abut against the upper part of the lifting platform 8.

[0052] 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 support 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.

[0053] 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, so that the stability of the lifting platform 8 during cutting or welding can be effectively ensured.

[0054] In the embodiment, the sliding table 7 is fixedly installed with a dust suction nozzle 21 for sucking the smoke dust generated during cutting and welding, the dust suction nozzle 21 is communicated with an air extractor 22 at the air outlet end, one end of the air extractor 22 is communicated with a dust discharge pipe 23, and the air outlet end of the dust discharge pipe 23 is communicated with a water tank 24.

[0055] It should be noted that the air guide pipe communicated between the dust suction nozzle 21 and the air extractor 22 is set as a redundant pipe.

[0056] Referring toFigure 1 、 Figure 2 and Figure 12 Specifically, the dust exhaust pipe 23 is provided as a spiral pipe, a filter 27 is fixedly installed on the dust exhaust pipe 23, and a baffle 28 for colliding with the airflow is arranged in the dust exhaust pipe 23.

[0057] It should be noted that the filter 27 is provided as a Y-shaped filter.

[0058] With the above scheme, during cutting or welding, the exhaust fan 22 works to make the dust suction nozzle 21 generate suction force, and the dust suction nozzle 21 sucks dust into the dust exhaust pipe 23. Due to the spiral characteristic 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, thereby reducing dust discharge and improving air quality in the working environment.

[0059] The above embodiment has the following beneficial effects: 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. 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 after leaving, the device is closed, which can effectively save resources and has a simple structure and convenient operation. When the motor 5 works, the lead screw 9 rotates, the circular motion of the lead screw 9 is converted 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 protruding block 12 presses the bearing 15, and the fixed pipe 16 and the telescopic rod 17 are limited in position, so that the lifting table 8 moves upward along the lifting direction of the telescopic rod 17, 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. 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 where the lifting table 8 is raised to the highest point, and provides buffering, which can effectively ensure the stability of the lifting table 8 during cutting or welding. 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.
