[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] See also Figures 1 to 14 , five embodiments provided by the present invention are:

[0043] Embodiment 1:

[0044] A precision rolling mill lathe, comprising a lathe structure 100, a fixing structure 200, a protection structure 300, a suction structure 400 and a mounting structure 500, wherein the lathe structure 100 comprises a base 113, a travel plate 104 symmetrically distributed above the base 113, a frame 101 located at the upper end of the travel plate 104, a mounting column 102 symmetrically distributed and fixed to the inner wall of the frame 101, a mounting plate 105 sleeved on the outer wall of the mounting column 102, and a rotating chuck 103 located at the opposite end of the mounting column 102;

[0045] The upper end of the base 113 is provided with two sets of symmetrically distributed guide rails 109, and the lower end of the travel plate 104 is provided with a slider 111 which is symmetrically distributed and slidably installed inside the guide rail 109;

[0046] A motor 106 is arranged at the upper end of the base 113, a symmetrically distributed bearing bracket 112 is arranged at the upper end of the base 113, a screw 108 rotatably mounted inside the bearing bracket 112 and with outer wall threads relatively distributed is arranged at the output end of the motor 106, a nut 110 sleeved on the outer side of the screw 108 and threadedly mounted with the screw 108 is arranged at the lower end of the stroke plate 104, and an electromagnetic brake 107 is sleeved on the outer side of the output end of the motor 106;

[0047] When the motor 106 is running, it drives the screw 108 to rotate. Because the stroke plate 104 is supported by a lateral sliding movement inside the guide rail 109 through the slider 111, the nuts distributed relatively on the outer wall of the screw 108 push the nut 110, and the nut 110 moves away from each other, driving the stroke plate 104 to move away from each other. The roller is moved and suspended above the base 113 using a handling device. The motor 106 drives the shaft to rotate in the opposite direction, driving the screw 108 to support in the opposite direction, thereby pushing the nut 110 to move relatively, and the stroke plate 104 achieves relative movement. The frame 101 drives the mounting column 102 and the rotating chuck 103 to move relatively with the stroke plate 104. The rotating chuck 103 clamps the two ends of the roller. During the use of the electromagnetic brake 107, the electric When current passes through the coil, a magnetic field is generated. When the magnetic field interacts with the rotating metal parts, a force that hinders the movement is generated. Usually, when the power is stopped, the motor 106 still has rotational inertia. The electromagnetic brake 107 uses this characteristic to generate a magnetic field through electromagnetic induction when the motor 106 is powered off, and quickly slows down or completely stops the rotation of the motor, thereby braking the motor 106. Motor 2 501 and motor 3 204 are both used in conjunction with the electromagnetic brake 107 to prevent the screw 108 connected to the motor 106 from rotating, thereby ensuring the stability of the roller clamped by the rotating chuck 103 of the stroke plate 104 shell, and ensuring the stable processing of the roller. The rotating chuck 103 can move away from each other during use, which is convenient for loading and unloading the roller processed by the lathe, and the convenience of loading and unloading the roller is improved.

[0048] Embodiment 2:

[0049] The mounting structure 500 includes a fixing sleeve 506 suspended above the travel plate 104 and a mounting plate 507 fixed to the inner wall of the fixing sleeve 506;

[0050] A guide frame 504 is provided at the upper end of the base 113, a guide seat 503 slidably mounted with the guide frame 504 is provided at the rear end of the fixed sleeve 506, a motor 501 is provided at one side of the upper end of the base 113, a nut 502 is provided at the front end of the guide seat 503, a symmetrically distributed bearing bracket 505 is provided at the upper end of the base 113, and a screw 508 rotatably inserted in the bearing bracket 505 and threadedly mounted with the nut 502 is provided at one end of the motor 501;

[0051] When the motor 2 501 is in operation, it drives the screw 2 508 to rotate. Since the guide frame 504 is slidably installed on the guide seat 503, the motor 2 501 drives the screw 2 508 to rotate inside the nut 2 502. The screw 2 508 pushes the threaded raceway inside the nut 2 502, thereby driving the guide frame 504 to move laterally. It is worth mentioning that a structure for turning or grinding the roller is installed on the mounting plate 507. When the guide frame 504 moves laterally, it drives the fixed sleeve 506 and the mounting plate 507, as well as the turning or grinding processing structure on the upper end of the mounting plate 507, to move laterally, and the outer wall of the roller rotated by the rotating chuck 103 is effectively turned or ground through the processing structure.

[0052] Embodiment three:

[0053] The protective structure 300 includes a storage sleeve 301 fixedly placed at one end opposite to the mounting plate 105, a cylindrical shielding cover 302 located on the inner wall of the storage sleeve 301 and sleeved on the outer side of the mounting column 102, a docking ring 304 located at one end of the shielding cover 302, a plurality of symmetrically distributed rotating arms 1 305 located on the outer side of the shielding cover 302, a plurality of symmetrically distributed rotating arms 2 306 located between the rotating arms 1 305 and distributed at equal intervals, a second rivet 308 rotatably mounted at the intersection of the first rotating arm 305 and the second rotating arm 306, a steel ring 303 rotatably distributed on the outer wall of the shielding cover 302 at equal intervals, and a connecting strip 312 rotatably mounted at the lower end of the second rivet 308 and connected to the steel ring 303;

[0054] The inner wall of one side of the storage sleeve 301 is provided with a guide rail 2 310 distributed in a circular array, one end of the rotating arm 1 305 and the rotating arm 2 306 is rotatably mounted with a rotating seat 309, one end of the rotating seat 309 is provided with a slider 2 311 slidably mounted on the outer wall of the guide rail 2 310, and the side cross connection of the rotating arm 1 305 and the rotating arm 2 306 is rotatably mounted with a rivet 1 307;

[0055] One end of the docking ring 304 is provided with positioning rods 313 distributed in a circular array, and the interior of the fixing sleeve 506 is provided with positioning holes 314 distributed in a circular array, and one end of the positioning rods 313 is slidably inserted into the positioning holes 314;

[0056] During the roller processing, the docking ring 304 is inserted into the positioning hole 314 through the positioning rod 313. During this process, the docking ring 304 pulls the shielding cover 302 located inside the storage sleeve 301 to extend, and at the same time applies a pulling force to the rotating arm 1 305 and the rotating arm 2 306, and the rotating arm 1 305 and the rotating arm 2 306 are rotationally supported at the center through the rivet 2 308, and the rivet 2 308 is used to support the rotating arm 1 305 and the rotating arm 2 306 at the corners. One end of the second movable arm 306 rotates inside the rotating seat 309, and the second slider 311 slides relatively on the outer wall of the second guide rail 310, so that the first rotating arm 305 and the second rotating arm 306 are extended and connected to the lower end of the second rivet 308 for rotation. Because the rotating and extended rotating arm 305 and the second rotating arm 306 are supported, the connecting bar 312 applies a pulling force to the steel bar, so that the extended shielding cover 302 is stably extended and retracted, thereby preventing the shielding cover 302 from dripping onto the outer wall of the rotating roller during the processing;

[0057] After the docking ring 304 and the fixed sleeve 506 are installed, waste materials such as debris and dust generated by the rolling mill processing are intercepted, avoiding the diffusion of metal dust in the working environment. Not only does it adhere to the equipment and is difficult to clean, the environment is filled with metal dust, resulting in a poor working environment. Inhalation of metal dust by workers will also cause damage to the respiratory system of the body. The debris generated by turning is avoided from directly accumulating on the processing equipment, causing problems such as difficulty in cleaning. The debris and dust generated by the processing are directly intercepted, which improves the working environment, protects the workers, improves the cleanliness of the equipment during use, and avoids debris from entering the mechanical mechanism and affecting the stability of the equipment during use.

[0058] Embodiment 4:

[0059] The suction structure 400 includes a negative pressure cylinder 404 fixed to the rear side of the upper end of the frame 101 and symmetrically distributed, a negative pressure pipe 405 connected to the negative pressure cylinder 404, and a negative pressure cover 406 connected to the negative pressure pipe 405 and the storage sleeve 301 and penetrating the inner wall of the shielding cover 302;

[0060] A motor 3 204 is disposed at the upper end of the fixing seat, a gear 206 is disposed at the output end of the motor 3 204, and a gear ring 207 meshing with the gear 206 is disposed on the outer wall of one side of the adjusting ring 205;

[0061] The side ring 203 is embedded with a sliding sleeve 208 distributed in an annular array, and a guide rod 214 is slidably inserted in the sliding sleeve 208. A support block 212 is provided at the lower end of the guide rod 214. A spring 213 fixed between the support block 212 and the side ring 203 is sleeved on the outer side of the guide rod 214.

The inner wall of the adjusting ring 205 is provided with extrusion blocks 209 distributed in an annular array and with a conical inner wall.

[0062] During the process of the roller being processed by the lathe, after the protective cover is connected to the fixed sleeve seat 506, the motor 3 204 operates to drive the gear 206 to rotate, and the gear 206 pushes the ring gear 207. Because the adjusting ring 205 rotates inside the ring seat 201 through the rotating ring 202, it is pushed by the ring gear 207, and the rotating ring 202 rotates. When the rotating ring 202 rotates, it drives the extrusion block 209 to rotate with the center of the rotating ring 202 as the axis, and the rotation squeezes the ball 210 through the extrusion block 209, and the ball 210 is forced through the cone plate 2 11 acts on the support block 212 and the spring 213. The spring 213 is stretched longitudinally and slides inside the sliding sleeve 208 through the guide rod 214 to guide the sliding of the cone plate 211. The cone plate 211 descends and squeezes the outer wall of the docking ring 304. The linkage of multiple cone plates 211 and the squeezing block 209 realizes the pressing and fixing of the docking ring 304 at multiple positions. The docking ring 304 is automatically fixed during the installation process, which is convenient for the use of the protective structure 300 and improves the stability of the protective structure 300 during use.
