[0016] 1. In the present invention, an integrated turning processing device suitable for screws of different radii is designed, and a fixing mechanism in the device is used to clamp the screw. The controller starts the servo motor, and the servo motor drives the driving screw to rotate. The rotating driving screw drives the sliding seat and the fixed seat to one end of the center position of the base through the sliding nut. The two sets of fixed seats drive the clamping seats to approach each other. When the distance between the two sets of clamping seats is adapted to the length of the screw to be processed, the controller turns off the servo motor, and the servo motor no longer drives the driving screw to rotate. The fixed seat and the clamping seat no longer move, and the screw to be processed is placed between the two sets of clamping seats. The screw to be processed will be inserted into the clamping groove in the clamping seat, and the controller starts the micro air pump. The micro air pump will send air into the clamping seat through the guide sleeve and the guide groove. The air entering the clamping seat will flow into the clamping seat through the guide pipe. In the fixed sleeve, the air entering the fixed sleeve will push the piston plate and the clamping push rod to move inward, and the clamping push rod moving inward will be close to the screw to be processed. When the clamping push rod presses against the outer wall of the screw to be processed, the piezoelectric ceramic piece on the outer wall of the clamping push rod is squeezed to generate current and inputs the current signal into the controller. After the controller receives the current signal generated by the piezoelectric ceramic piece, the controller closes the solenoid valve corresponding to the clamping push rod, and the air no longer enters the corresponding fixed sleeve. The clamping push rod will clamp the screw to be processed, and the moving distance of the clamping push rod is adjusted according to the shape of the screw to be processed, so that the clamping push rod can clamp screws of different radii and irregular shapes, which solves the problem that the existing integrated turning processing device generally uses an electric chuck to fix screws of different radii, and the electric chuck has poor clamping effect on screws of irregular shapes.

[0017] 2. In the present invention, an integrated turning processing device suitable for screws with different radii is designed, and the turning tool mechanism in the device is used to install the cutting turning tool. When replacing the turning tool, the internal threaded sleeve is rotated, the internal threaded sleeve will be screwed outward, the fixing bolt is disengaged from the internal threaded sleeve, the cutting turning tool is pulled, the cutting turning tool is extracted from the connecting seat, and then a new cutting turning tool is inserted into the connecting seat. The internal threaded sleeve is rotated in the opposite direction, the fixing bolt is screwed into the internal threaded sleeve, and the new cutting turning tool is fixed in the connecting seat. The installation and removal of the cutting turning tool is relatively convenient, which solves the problem that the installation and removal of the turning tool of the existing integrated turning processing device are complicated and inconvenient to use.

[0018] 3. In the present invention, an integrated turning processing device suitable for screws of different radii is designed, and a protective strip in the device is used to prevent the cut chips from entering the base, which facilitates the cleaning of the chips and prevents the chips from adhering to the driving screw and affecting the movement of the sliding nut.

[0036] In this embodiment, reference Figure 1 and Figure 7 The turning tool mechanism 3 includes an electric slide rail 301 fixedly connected to the inside of the base 1, a slide table 302 is installed on the outer wall of the electric slide rail 301, a turning tool holder 303 is fixedly connected to the top of the slide table 302, the outer wall of the turning tool holder 303 and the position near the fixing mechanism 2 are fixedly connected to the electric push rod 304, the outer wall of the electric push rod 304 is fixedly connected to the connecting seat 305, the interior of the connecting seat 305 is slidably connected to the cutting turning tool 306, the outer wall of the cutting turning tool 306 and the position near the connecting seat 305 are fixedly connected to the connecting plate 307, the outer wall of the connecting plate 307 is rotatably connected to the internal threaded sleeve 308, and the inner wall of the connecting seat 305 and the corresponding position of the internal threaded sleeve 308 are fixedly connected to the fixing bolt 309;

[0037] The tool holder 303, the connecting seat 305 and the connecting plate 307 are all made of stainless steel. The tool holder 303 is an L-shaped structure. The cutting tool 306 passes through and extends to the outside of the connecting seat 305. The connecting seat 305 is a concave structure. The electric push rod 304, the electric slide rail 301 and the controller 5 are all connected electrically. Two groups of internal threaded sleeves 308 and fixing bolts 309 are provided. The fixing bolts 309 pass through and extend into the internal threaded sleeve 308. The connection between the internal threaded sleeve 308 and the fixing bolts 309 is a threaded connection.

[0038] The working process of the present invention is as follows: when the integrated turning processing device for screws with different radii designed by the present invention is in operation, the controller 5 starts the servo motor 4, and the servo motor 4 drives the driving screw 201 to rotate. The rotating driving screw 201 drives the sliding seat 203 and the fixed seat 204 to move toward the center position of the base 1 through the sliding nut 202. The two groups of fixed seats 204 drive the clamping seats 206 to approach each other. When the distance between the two groups of clamping seats 206 is adapted to the length of the screw to be processed, the screw to be processed is placed between the two groups of clamping seats 206. The screw to be processed is inserted into the clamping groove 212 in the clamping seat 206. The controller 5 turns off the servo motor 4. The servo motor 4 no longer drives the driving screw 201 to rotate. The fixed seat 204 and the clamping seat 206 no longer move. The controller 5 starts the micro air pump 209 , the micro air pump 209 will send air into the clamping seat 206 through the guide sleeve 208 and the guide groove 207. The air entering the clamping seat 206 will flow into the fixed sleeve 214 through the guide tube 217. The air entering the fixed sleeve 214 will push the piston plate 215 and the clamping push rod 213 to move inward. The inward-moving clamping push rod 213 will approach the screw to be processed. When the clamping push rod 213 is against the outer wall of the screw to be processed, the piezoelectric ceramic piece 216 on the outer wall of the clamping push rod 213 receives the squeeze to generate current and inputs the current signal into the controller 5. After the controller 5 receives the current signal generated by the piezoelectric ceramic piece 216, the controller 5 closes the solenoid valve 218 corresponding to the clamping push rod 213, and the air no longer enters the corresponding fixed sleeve 214. The clamping push rod 213 will clamp the screw to be processed;

[0039] The controller 5 activates the electric push rod 304, which drives the cutting tool 306 to move backward through the connecting seat 305. The cutting tool 306 moving backward will be close to the outer wall of the screw to be processed. The controller 5 activates the electric slide 301 and the rotating motor 211. The rotating motor 211 drives the processing screw to rotate through the rotating shaft 205 and the clamping seat 206. The electric slide 301 drives the tool holder 303 and the cutting tool 306 to move on the rotating processing screw through the slide 302. The moving cutting tool 306 will turn the processing screw. The waste chips generated by turning will fall onto the base 1. The protective strip 222 will prevent the waste chips from entering the interior of the base 1.

[0040] After the turning is completed, the electric push rod 304 drives the cutting tool 306 to move forward through the connecting seat 305. The cutting tool 306 moving forward is away from the processing screw. The controller 5 turns off the rotating motor 211. The rotating motor 211 no longer drives the clamping seat 206 and the processing screw to rotate. The controller 5 opens the solenoid valve 218. The micro air pump 209 extracts the air in the fixed sleeve 214 through the guide sleeve 208, the guide groove 207 and the guide pipe 217. The air pressure in the fixed sleeve 214 is reduced, and the reset spring 219 will pull the piston plate 215 and the clamping push rod 213 to move in the opposite direction. The clamping push rod 213 that moves in the opposite direction no longer presses against the processing screw. The controller 5 starts the servo motor 4. The servo motor 4 will drive the driving screw 201 to rotate in the opposite direction. The driving screw 201 that rotates in the opposite direction drives the sliding seat 203 and the fixed seat 204 to move in the opposite direction through the sliding nut 202. The two sets of fixed seats 204 drive the clamping seats 206 to move away from each other. The clamping seats 206 no longer clamp the processing screw, and the processing screw is removed from the clamping seat 206.

[0041] When replacing the turning tool, rotate the internal threaded sleeve 308, the internal threaded sleeve 308 will be screwed outward, the fixing bolt 309 will be disengaged from the internal threaded sleeve 308, pull the cutting turning tool 306, and extract the cutting turning tool 306 from the connecting seat 305, then insert the new cutting turning tool 306 into the connecting seat 305, rotate the internal threaded sleeve 308 in the opposite direction, the fixing bolt 309 will be screwed into the internal threaded sleeve 308, and the new cutting turning tool 306 will be fixed in the connecting seat 305.

[0042] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
