In this way, the installation speed of the rolling roller is improved and the operation process is safer.

[0048] The lifting unit 300 includes a driving assembly 307 and an extrusion cover 301. The driving assembly 307 includes a driving screw shaft 3074. A driving motor 3073 is installed on one side of the driving screw shaft 3074. A screw collar 3075 is meshedly arranged on the driving screw shaft 3074. The screw collar 3075 is connected to the extrusion cover 301. An extrusion block 302 is inserted inside the extrusion cover 301, and the extrusion block 302 is movably inserted in an installation cavity 3011 opened inside the extrusion cover 301.

A push rod 305 is squeezed at the bottom of the pry bar 305. 06; By setting up a lifting unit, when lifting the end of the roller, the driving motor drives the driving screw shaft to rotate, and then drives the extrusion cover to move toward the installed end of the roller. When the roller contacts the extrusion block, the extrusion block can move inward until the extrusion block moves to the bottom, and the end face of the roller is limited by the extrusion block. During the movement of the extrusion block, the extrusion block pushes the connecting arm to move, and the connecting arm drives the pry bar at the end to rotate. The pry bar pushes the push rod downward, and finally the four sides of the roller can be limited to ensure that the roller can only rotate along the rotation center without deformation, and finally the cutting process is more precise.

[0049] The unlocking unit 400 includes an unlocking cover 401, a slide seat 4011 is slidably arranged inside the unlocking cover 401, an inclined guide groove 4012 is provided on the slide seat 4011, an unlocking rod 402 is slidably arranged on the guide groove 4012, one side of the unlocking rod 402 is connected to the extrusion block 302, a vertical rod 403 is arranged at the bottom of the slide seat 4011, and a flat plate 4031 is arranged on the vertical rod 403, a synchronous plate 404 is overlapped on the flat plate 4031, and a card block 4051 is arranged at the bottom of the synchronous plate 404, and the card block 4051 is carded in the card groove 4052, and the card Groove 4052 is provided on the positioning shaft 1042 installed at the end of the feed screw shaft 104; by providing an unlocking unit, when the lifting unit is installed and rotated, the internal extrusion block pushes the unlocking rod to slide inside the guide groove, driving the slide seat and the vertical rod with the guide groove to slide upward, and the vertical rod pulls the bottom plate upward, and finally pulls the synchronous plate and the card block upward, so that the card block and the card slot are separated, so that the locking state of the feed screw shaft is unlocked, thereby ensuring that when the roller is installed, the cutting tool holder can move on the feed screw shaft, thereby achieving the purpose of safety protection.

[0050] The reset unit 500 includes an insert rod 5021, which movably penetrates the lifting sleeve 105 and the ejector rod 106. A swing arm 502 is movably provided on the insert rod 5021, a pull rod 501 is provided on the swing arm 502, and a guide block 5013 is provided on the pull rod 501. The guide block 5013 corresponds to the L-shaped plate 503 installed on the extrusion cover 301. By providing the reset unit, when the extrusion cover moves, the L-shaped plate at the bottom of the extrusion cover contacts the guide block, the guide block is pressed downward, and the pull rod is pushed to slide downward, and the insert rod is removed from the ejector rod through the swing arm, thereby unlocking the positioning state of the ejector rod, and the ejector rod automatically falls, so that when the cutting tool holder is used for processing later, there will be no interference with the ejector rod, ensuring that the turning work can be carried out smoothly.

[0051] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 8As shown, in a specific embodiment, a guide rail 1051 is horizontally arranged at the bottom of the collection box 102, a pair of lifting sleeves 105 are slidably arranged on the guide rail 1051, the guide rail 1051 is in a straight line shape, blocking blocks 1052 are installed at both ends of the guide rail 1051, a friction plate 1061 is arranged on the top of the push rod 106, the friction plate 1061 is in contact with the roller 200, and a synchronization rod 1063 is installed between adjacent push rods 106. The rolling roller 200 is placed as a whole on the friction plate 1061 on the push rod 106, and the friction force on the friction plate 1061 ensures that the rolling roller 200 will not move left or right. Then the operator pulls the synchronization rod 1063, and the push rod 106 on the side wall is pulled to move by the synchronization rod 1063. The push rod 106 drives the bottom lifting sleeve 105 to move along the guide slide rail 1051. At the same time, the rolling roller 200 on the push rod 106 moves horizontally and can be directly moved to the three-jaw chuck on the turning lathe body 101, and is clamped and installed by the three-jaw chuck.

[0052] Embodiment 2, based on the above embodiment and the difference between this embodiment and the present embodiment is: Fig. 9 , Fig.10 and Fig.11 As shown, an inner groove 3012 is provided on the extrusion cover 301, the extrusion cover 301, the rolling roller 200 and the three-jaw chuck on the lathe body 101 are located on the same axis, the pressure rod 303 is movably inserted in the inner groove 3012, and a ejector pin 3021 is installed on the extrusion block 302 located outside the extrusion cover 301. A guide sleeve 3031 is installed on the inner wall of the extrusion cover 301, and a pressure plate 3032 is slidably arranged inside the guide sleeve 3031, a pressure rod 303 is fixedly arranged on the pressure plate 3032, the pressure rod 303 movably passes through the guide sleeve 3031, and the pressure rod 303 is fixedly connected to the extrusion block 302, an unlocking rod 402 is penetrated inside the pressure rod 303, the unlocking rod 402 movably passes through the extrusion cover 301 and the unlocking cover 401, the unlocking cover 401 is installed on the back of the extrusion cover 301, and a guide wheel 4021 is installed on the unlocking rod 402, the guide wheel 4021 is slidably connected to the guide groove 4012, and a first spring 3033 is clamped on the pressure plate 3032 and the guide sleeve 3031. After the extrusion cover 301 and the roller 200 are in contact, the internal ejector pin 3021 and the extrusion block 302 are opened and move into the installation cavity 3011, pushing the pressure rod 303 and the pressure plate 3032 to move inward, squeezing the internal first spring 3033, and the first spring 3033 also facilitates the subsequent resetting of the extrusion block 302.

[0053] like Fig. 9 , Fig.10 and Fig.11As shown, in a specific embodiment, a rotating shaft is provided at the rotation center of the pry bar 305, and mounting seats 3051 are movably provided at both ends of the rotating shaft, and the mounting seats 3051 are welded and arranged on the inner wall of the mounting cavity 3011, and a torsion spring is sleeved on the rotating shaft, one side of the torsion spring is clamped on the mounting seat 3051, and the other side of the rotating shaft is clamped on the pry bar 305, and a slide groove 3052 is provided inside the pry bar 305, and a slide bar 3041 is slidably provided on the slide groove 3052, and the slide bar 3041 is fixedly connected to the connecting arm 304. A push plate 3061 is fixedly provided at the bottom of the push rod 306, and a plurality of pairs of rolling balls 3062 are provided on the push plate 3061, and a second spring 3063 is sleeved on the push plate 3061, and one side of the second spring 3063 is clamped on the push plate 3061, and the other side of the second spring 3063 is clamped on the inner wall of the inner groove 3012. After the extrusion block 302 moves, the position of the connecting arm 304 of the side wall is moved synchronously. The connecting arm 304 pushes the sliding rod 3041 at the end to slide inside the sliding groove 3052 on the pry bar 305, and finally the pry bar 305 can rotate around the rotating shaft on the mounting seat 3051. The other side of the pry bar 305 will squeeze the push rod 306. At this time, the push rod 306 drives the push plate 3061 to slide downward, and finally ensures that the rolling ball 3062 contacts the roller 200, thereby limiting the circumference of the roller 200.

[0054] Embodiment 3, based on the above embodiment and the difference between this embodiment and the present embodiment is: Figure 8 As shown, a crossbeam 3071 is horizontally arranged on the lathe body 101, and the housing of the drive motor 3073 is installed on the side wall of the crossbeam 3071. A mounting groove 3072 is opened on the lathe body 101. A drive screw shaft 3074 is movably arranged inside the mounting groove 3072, and a screw ring 3075 slides in the mounting groove 3072. A replaceable connecting rod 3076 is screwed between the screw ring 3075 and the extrusion cover 301, and a limit rod 3077 is movably arranged inside the connecting rod 3076, and the limit rod 3077 is installed on the lathe body 101. Then the operator needs to start the driving motor 3073, which drives the driving screw shaft 3074 connected to the output shaft to rotate. A screw ring 3075 is meshed on the driving screw shaft 3074. The screw ring 3075 slides in the installation groove 3072 and is limited. The screw ring 3075 pulls the connecting rod 3076 to slide along the limiting rod 3077, and moves the extrusion cover 301 connected to the bottom toward the side of the roller 200.

[0055] like Figure 4 , Figure 5 and Figure 8As shown, in a specific embodiment, guide rods 4041 are movably inserted at both ends of the synchronization plate 404, the bottom of the guide rod 4041 is welded to the installation cover 1031, a partition 4042 is fixedly arranged on the top of the guide rod 4041, the size of the partition 4042 is larger than the guide rod 4041, a fixing block 4043 is arranged on the installation cover 1031, the fixing block 4043 and the synchronization plate 404 are overlapped with each other, and the flat plate 4031 is inserted in the gap between the synchronization plate 404 and the installation cover 1031. A lifting bracket 405 is fixedly arranged at the bottom of the synchronization plate 404, the lifting bracket 405 is L-shaped, the lifting bracket 405 movably passes through the side wall of the installation cover 1031, and a clamping block 4051 is arranged at the end of the lifting bracket 405. The vertical rod 403 drives the flat plate 4031 to move upward, and the flat plate 4031 pushes the synchronous plate 404 to slide upward along the guide rod 4041, wherein the partition plate 4042 serves the purpose of limiting. The synchronous plate 404 drives the lifting bracket 405 and the block 4051 to move upward. When the block 4051 and the slot 4052 are separated, the positioning shaft 1042 with the slot 4052 is unlocked, and the feed screw shaft 104 is unlocked synchronously, ensuring that the cutting tool holder 103 can move on the feed screw shaft 104 after the roller 200 is installed, thereby achieving the purpose of safety protection.

[0056] like Figure 4 , Figure 6 , Figure 7 and Figure 8 As shown, further, a baffle plate 5022 is installed on the insertion rod 5021, and the baffle plate 5022 is slidably set in a groove opened on the side wall of the jacking sleeve 105. The end of the insertion rod 5021 is inserted into the hole 1062 opened on the side wall of the jacking sleeve 106. A positioning plate 5011 is movably inserted into the side wall of the pull rod 501. Both ends of the positioning plate 5011 are installed on the jacking sleeve 105. A third spring 5012 is arranged on the positioning plate 5011. The third spring 5012 is clamped on the guide block 5013 and the positioning plate 5011, and the surface of the guide block 5013 is chamfered. When the extrusion cover 301 is about to approach the rolling roller 200, the L-shaped plate 503 at the bottom of the extrusion cover 301 moves in the direction of the guide block 5013. The guide block 5013 is squeezed and starts to slide downward, driving the surface-mounted pull rod 501 to move downward, and the connected third spring 5012 is compressed. The third spring 5012 facilitates the subsequent resetting of the pull rod 501. The pull rod 501 moves downward to pull the swing arm 502 to change its position, thereby driving the insertion rod 5021 at the end of the swing arm 502 to move horizontally, so that the insertion rod 5021 is separated from the inside of the socket 1062, allowing the push rod 106 and the lifting sleeve 105 to be unlocked, and the push rod 106 slides downward due to the action of gravity, so that the friction plate 1061 and the rolling roller 200 are separated, which is convenient for the subsequent turning operation.

[0057] The implementation principle of a turning device for metal cold rolling roller processing in this embodiment is as follows:

[0058] When cutting operation is needed, the operator first places the roller 200 as a whole on the friction plate 1061 on the push rod 106, and the friction force on the friction plate 1061 ensures that the roller 200 will not move left or right. Then the operator pulls the synchronization rod 1063, and the push rod 106 on the side wall is pulled to move by the synchronization rod 1063. The push rod 106 drives the bottom lifting sleeve 105 to move along the guide slide rail 1051. At the same time, the roller 200 on the push rod 106 moves horizontally and can be directly moved to the three-jaw chuck on the turning lathe body 101, and is clamped and installed by the three-jaw chuck.

[0059] Then the operator needs to start the driving motor 3073, which drives the driving screw shaft 3074 connected to the output shaft to rotate. A screw ring 3075 is meshed on the driving screw shaft 3074. The screw ring 3075 slides in the installation groove 3072 and is limited. The screw ring 3075 pulls the connecting rod 3076 to slide along the limiting rod 3077, and moves the extrusion cover 301 connected to the bottom toward the side of the roller 200.

[0060] When the extrusion cover 301 is about to approach the rolling roller 200, the L-shaped plate 503 at the bottom of the extrusion cover 301 moves in the direction of the guide block 5013. The guide block 5013 is squeezed and starts to slide downward, driving the surface-mounted pull rod 501 to move downward, and the connected third spring 5012 is compressed. The third spring 5012 facilitates the subsequent resetting of the pull rod 501. The pull rod 501 moves downward to pull the swing arm 502 to change its position, thereby driving the insertion rod 5021 at the end of the swing arm 502 to move horizontally, so that the insertion rod 5021 is separated from the inside of the socket 1062, allowing the push rod 106 and the lifting sleeve 105 to be unlocked, and the push rod 106 slides downward due to the action of gravity, so that the friction plate 1061 and the rolling roller 200 are separated, which is convenient for the subsequent turning operation.

[0061] After the extrusion cover 301 and the roller 200 come into contact, the internal ejector pin 3021 and the extrusion block 302 begin to move into the installation cavity 3011, pushing the pressure rod 303 and the pressure plate 3032 to move inward, squeezing the internal first spring 3033, and the first spring 3033 also facilitates the subsequent resetting of the extrusion block 302.

[0062] After the extrusion block 302 moves, the position of the connecting arm 304 of the side wall is moved synchronously. The connecting arm 304 pushes the sliding rod 3041 at the end to slide inside the sliding groove 3052 on the pry bar 305, and finally the pry bar 305 can rotate around the rotating shaft on the mounting seat 3051. The other side of the pry bar 305 will squeeze the push rod 306. At this time, the push rod 306 drives the push plate 3061 to slide downward, and finally ensures that the rolling ball 3062 contacts the roller 200, thereby limiting the circumference of the roller 200.

[0063] During the movement of the extrusion block 302, the unlocking rod 402 on the surface begins to move inward, and the guide wheel 4021 on the unlocking rod 402 slides inside the guide groove 4012. Since the guide groove 4012 is in an inclined state, it can eventually drive the slide 4011 to slide upward, and pull the vertical rod 403 on the surface to slide upward, and the vertical rod 403 drives the flat plate 4031 to move upward, and the flat plate 4031 pushes the synchronous plate 404 to slide upward along the guide rod 4041, wherein the partition plate 4042 serves the purpose of limiting, and the synchronous plate 404 drives the lifting bracket 405 and the block 4051 to move upward. When the block 4051 and the slot 4052 are separated, the positioning shaft 1042 with the slot 4052 is unlocked, and the feed screw shaft 104 is unlocked synchronously, ensuring that the cutting tool holder 103 can move on the feed screw shaft 104 after the roller 200 is installed, thereby achieving the purpose of safety protection.

[0064] Then, the lathe body 101 drives the clamped roller 200 to rotate, and the stepping motor 1041 drives the feed screw shaft 104 to rotate, driving the cutting tool holder 103 to move, so that the clamped roller 200 can be cut.
