[0019] Exemplarily, the rotating screws are provided in two groups, and the two groups of rotating screws are spaced apart from each other in a direction perpendicular to the guide column;

[0020] Among them, each group of the rotating screws corresponds to two groups of the pushing plates, and the power output end of the first drive motor is fixedly connected to one of the rotating screws. A belt transmission member is provided between the two groups of the rotating screws, and the belt transmission member is used to drive the two rotating screws to rotate synchronously.

[0021] In a possible implementation, the limiting component includes:

[0022] A limiting member is provided on the corresponding fixed platform or movable platform to form a limiting end of the limiting assembly;

[0023] A first stud is vertically inserted into the fixed platform or the movable platform; one end of the first stud is fixed to the limiting member, and the other end extends downward into the fixed platform or the movable platform; and

[0051] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0052] It should be noted that when an element is referred to as being “disposed on” another element, it may be directly on the other element or indirectly on the other element. It should be understood that the terms “upper,” “lower,” “front,” “rear,” “top,” “bottom,” “inside,” “outside,” etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended only to facilitate the description of the present invention and simplify the description. They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be construed as limiting the present invention.

[0053] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the technical features being referred to. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0054] It should be noted that the cutting and grinding devices used in traditional technologies are often arranged in parallel and are both arranged above the workpiece to be processed, which takes up a large space and has poor flexibility. After the cutting is completed, the workpiece to be processed needs to be transported from the cutting position to the grinding position and fixed and limited twice in succession.

[0055] Moreover, when cutting the workpiece, especially when both ends of the workpiece are not cut off, the cutting chips formed during the cutting process will accumulate in the gap between the two cutting surfaces. The accumulated cutting chips will not only affect the cutting direction of the tool, but also further wear the cutting end face and side of the tool, affecting the service life of the tool.

[0056] Please also refer to Figures 1 to 5 The metal cutting, grinding and forming machine tool based on automatic control provided by the present invention is now described. The metal cutting, grinding and forming machine tool based on automatic control includes a machine base 1, a first drive component 2, two sets of limit components 3, a cutting mechanism 4 and a grinding mechanism 5; a fixed platform 11 and a movable platform 12 are provided at intervals on the top of the machine base 1; the movable platform 12 has the freedom to slide toward or away from the fixed platform 11; the first drive component 2 is provided on the machine base 1; the power output end of the first drive component 2 is connected to the movable platform 12 to drive the movable platform 12 to slide toward or away from the fixed platform 11; the two sets of limit components 3 are provided on the movable platform 12 and the fixed platform 11 in a one-to-one correspondence. ; Among them, when the two ends of the workpiece to be processed are correspondingly mounted on the fixed table 11 and the movable table 12, the two sets of limit assemblies 3 are used to limit the corresponding ends of the workpiece to be processed; the cutting mechanism 4 is arranged between the fixed table 11 and the movable table 12, and is placed below the movable table 12; the grinding mechanism 5 is arranged between the fixed table 11 and the movable table 12, and is placed above the movable table 12; wherein, after the cutting mechanism 4 cuts the workpiece to be processed into two parts, the movable table 12 is used to drive one of the parts to slide to a position away from the other part, so that the grinding mechanism 5 extends into between the two parts to grind the cut surface thereof.

[0057] It should be understood that after the cutting mechanism 4 cuts the workpiece, the cutting gap between the two parts is small. By moving one group of parts away from the other group of parts through the movable table 12, the distance between the two parts can be expanded, making it easier for the grinding tool to extend downward and grind the cutting surface.

[0058] Exemplarily, the metal cutting, grinding and forming machine tool based on automatic control also includes a controller, which is used to be electrically connected to the first drive component 2, two sets of limit components 3, the cutting mechanism 4 and the grinding mechanism 5 respectively; the controller is a structure integrated with multiple control elements, and the first drive component 2 drives the movement operation of the movable table 12, the limit component 3 controls the limit of the end of the workpiece to be processed, and the control of the cutting process and the grinding process are all individually controlled by each control element. The control principle and specific structure of this part belong to the existing technology and will not be repeated here.

[0059] Furthermore, the top surfaces of the movable table 12 and the fixed table 11 are flush, and the workpiece to be processed is placed between the movable table 12 and the fixed table 11 , which facilitates the operation of the cutting mechanism 4 and the grinding mechanism 5 .

[0060] It should be understood that since the limiting component 3 limits the end of the workpiece to be processed, after the cutting is completed, the ends of the two split bodies will still be fixed by the limiting component 3, and the split body forms a cantilever structure with one end limited, and the cutting surface can be directly exposed to the grinding mechanism 5 because it is far away from the limiting end, thereby facilitating the grinding operation.

[0061] It should be noted that the grinding mechanism 5 provided in the present application is provided above the movable table 12 and the fixed table 11, and corresponds to the cutting mechanism 4 up and down; further, the grinding mechanism 5 has the freedom to move along the sliding direction of the movable table 12, which is used to adjust the position of the grinding mechanism 5, so as to facilitate the grinding of the two split bodies separately; specifically, when there is only one group of grinding mechanisms 5, the grinding mechanism 5 grinds the two split bodies successively; preferably, there are two groups of grinding mechanisms 5, one group of grinding mechanisms 5 corresponds to the fixed table 11 up and down, and the other group of grinding mechanisms 5 corresponds to the movable table 12 up and down, so that the two split bodies can be polished at the same time by the grinding mechanism 5, thereby improving the grinding efficiency.

[0062] Exemplarily, the grinding mechanism 5 includes a grinding tool and a lifting assembly connected to the grinding tool and a moving part connected to the lifting assembly. The moving part is used to drive the lifting part and the grinding tool to slide along the sliding direction of the movable platform 12, and the lifting assembly is used to drive the grinding tool to move up and down, so as to approach each split body; specifically, the lifting assembly can choose one of a hydraulic lifting cylinder, a telescopic cylinder or an electric push rod; the moving part can rotate the screw mechanism; the specific structure of the lifting assembly and the moving part can be selectively set according to actual needs.

[0063] The metal cutting, grinding and forming machine tool based on automatic control provided by the present invention can fix the two ends of the workpiece to be processed respectively by two sets of limit assemblies 3, and cut the workpiece to be processed by the cutting mechanism 4 at the bottom. When the cutting is completed, there is no need to release the limit assemblies 3 of the two splits and then re-fix them. The movable table 12 can directly drive one of the splits to move to a position away from the other split, so that the grinding mechanism 5 can extend downward between the cutting surfaces of the two splits, thereby causing the grinding mechanism 5 to grind the cutting surfaces of the two splits. The machine tool device provided in this application can simplify the fixing and limiting steps, shorten the operation process, and improve the efficiency of workpiece cutting and grinding; and the movable table 12 provided in this application can move toward the fixed table 11, and can easily adjust the distance between the movable table 12 and the fixed table 11, so as to adapt to workpieces to be processed of different sizes and shapes, thereby improving the adaptability of this device. In addition, the cutting mechanism 4 and the grinding mechanism 5 are distributed above and below the workpiece to be processed. On the one hand, it can improve the space utilization and ensure the compactness of the structure of the device. On the other hand, the tool in this application cuts upward, which can make the cutting chips fall directly downward under the action of gravity. This can avoid the problem that the cutting chips accumulate in the cutting gap when the tool cuts downward, affecting the cutting direction and damaging the cutting surface of the tool, thereby effectively ensuring the cutting quality.

[0064] See also Figure 1 In some possible embodiments, the movable platform 12 and the fixed platform 11 are both annular platforms, each having an opening 13 extending along the sliding direction of the movable platform 12. A guide post 14 is provided in the opening 13 between the two annular platforms, and the movable platform 12 is slidably connected to the guide post 14. The limiting assembly 3 is provided in the opening 13 corresponding to the annular platform, and the limiting end of the limiting assembly 3 extends upward from the annular platform.

[0065] In this application, the movable platform 12 and the fixed platform 11 are annular platforms with a through-opening 13. This facilitates the placement of the stopper assembly 3 and the installation of guide posts 14, which allow the movable platform 12 to be slidably connected via the guide posts 14, thereby increasing the compactness and stability of the structure. Furthermore, the annular platform can intercept cutting and grinding chips outside the annular platform, preventing them from entering the annular platform and affecting the stopper assembly 3.

[0066] In addition, the limiting component 3 is arranged in the opening 13 and the limiting end extends upward, which is convenient for limiting the workpiece to be processed mounted on the annular table without affecting the cutting and grinding operations between the annular tables. At the same time, this structure is conducive to the compact layout of the overall device.

[0067] Specifically, the guide column 14 is provided with a plurality of protrusions, which are arranged at intervals around the circumference of the guide column 14, and grooves adapted to the protrusions are provided at both ends of the annular table. When the movable table 12 slides on the guide column 14, the protrusions are limited in the corresponding grooves to prevent the annular table from rotating and deviating.

[0068] See also Figure 2 In some embodiments, the first drive assembly 2 includes a first drive motor 21, a rotating screw 22 and two sets of push plates 23; the first drive motor 21 is arranged on the machine tool base 1; the rotating screw 22 is arranged parallel to the guide column 14 and is rotatably connected to the machine tool base 1; the rotating screw 22 is fixedly connected to the power output end of the first drive motor 21; the two sets of push plates 23 are arranged at intervals along the extension direction of the guide column 14, and correspondingly abut against the left and right sides of the movable platform 12; one end of the push plate 23 is slidably connected to the guide column 14, and the other end is screwed onto the rotating screw 22; wherein, when the first drive motor 21 drives the rotating screw 22 to rotate, the two sets of push plates 23 are used to push the movable platform 12 to slide left and right on the guide column 14.

[0069] The first drive motor 21 is used to drive the rotating screw 22 to rotate, thereby causing the push plate 23 to move left and right on the rotating screw 22; since the push plate 23 abuts against the left and right sides of the movable platform 12, the push plate 23 can push the movable platform 12 to slide left and right on the guide column 14.

[0070] In this application, the movable table 12 is pushed by pushing the plate 23 to slide on the guide column 14. The structure is simple and the transmission is stable, which can enable the movable table 12 to slide smoothly toward or away from the fixed table 11, providing a convenient position adjustment method for cutting and grinding operations.

[0071] Preferably, the rotating screw 22 and the guide column 14 are spaced apart from each other, the upper end of the pushing plate 23 is slidably connected to the guide column 14 , and the lower end is screwed to the rotating screw 22 .

[0072] Specifically, the push plate 23 is provided with a plurality of grooves that match the protrusions on the guide column 14 to guide the push plate 23 and prevent the push plate 23 from rotating and deviating. The lower end of the push plate 23 is provided with a threaded hole suitable for matching with the rotating screw 22, and the rotating screw 22 is screwed into the corresponding threaded hole.

[0073] See also Figure 1 or Figure 2 For example, two groups of rotating screws 22 are provided, and the two groups of rotating screws 22 are spaced apart in a front-to-rear manner along a direction perpendicular to the guide column 14; wherein, each group of rotating screws 22 corresponds to two groups of push plates 23, and the power output end of the first drive motor 21 is fixedly connected to one of the rotating screws 22, and a belt transmission member 24 is provided between the two groups of rotating screws 22, and the belt transmission member 24 is used to drive the two rotating screws 22 to rotate synchronously.

[0074] Specifically, the belt drive 24 includes two rotating wheels and a conveyor belt. The two rotating wheels are provided in a one-to-one correspondence with the two rotating screws 22, and the conveyor belt is wound around the two rotating wheels. The belt drive assembly is used to synchronize the rotation of the two rotating screws 22 to ensure the consistency of the front and rear movement of the movable platform 12.

[0075] By providing two sets of rotating screws 22 and rotating them synchronously through the belt transmission member 24, the movable platform 12 can be subjected to more uniform force and pushed more smoothly, thereby ensuring the stability and accuracy of the sliding of the movable platform 12 on the guide column 14, avoiding movement deviation caused by unilateral force, and helping to improve the accuracy of the device in processing the workpiece.

[0076] See also Figure 3 In some possible embodiments, the limiting assembly 3 includes a limiting member 31, a first stud 32 and a lifting drive member 33; the limiting member 31 is arranged on the corresponding fixed platform 11 or the movable platform 12 to form a limiting end of the limiting assembly 3; the first stud 32 is vertically penetrated into the fixed platform 11 or the movable platform 12; one end of the first stud 32 is fixed to the limiting member 31, and the other end extends downward into the fixed platform 11 or the movable platform 12; the lifting drive member 33 is arranged in the corresponding fixed platform 11 or the movable platform 12, and is dynamically connected to the extending end of the first stud 32; wherein the lifting drive member 33 is used to drive the limiting member 31 to move up and down through the first stud 32, so that the limiting member 31 is pressed down on the top of the workpiece to be processed.

[0077] Exemplarily, two groups of first studs 32 are provided. The two groups of first studs 32 are spaced apart in front and back along a direction perpendicular to the guide column 14 , and are both fixedly connected to the bottom of the limiting member 31 .

[0078] Optionally, the limiting member 31 is provided with a clearance hole extending axially through the guide column 14 so that when the workpiece to be processed is longer, the workpiece to be processed can pass through the clearance hole. At this time, the limiting column 312 of the limiting member 31 is located above the clearance hole.

[0079] The limiting assembly 3 drives the first stud 32 through the lifting drive member 33, so that the limiting member 31 moves up and down to press the top of the workpiece to be processed, which can effectively limit the workpiece to be processed on the top of the movable table 12 or the fixed table 11, ensuring the stability of the position of the workpiece to be processed during cutting and polishing, improving the processing accuracy, and this adjustable limiting method can adapt to workpieces of different thicknesses or shapes.

[0080] See also Figure 3In some embodiments, the limiting member 31 includes a lifting plate 311 and a plurality of limiting columns 312; the lifting plate 311 is arranged above the corresponding fixed platform 11 or the movable platform 12, and the bottom is fixed to the first stud 32; the plurality of limiting columns 312 are distributed at intervals on the lifting plate 311; one end of the limiting column 312 is detachably connected to the lifting plate 311, and the other end extends above the cutting mechanism 4 to be pressed against the top of the workpiece to be processed.

[0081] The lifting plate 311 of the limiting member 31 is fixed to the first stud 32. The lifting plate 311 is used to connect the first stud 32 to realize the lifting and lowering of the limiting member 31 and at the same time perform preliminary limiting on the end of the workpiece to be processed; when the lifting plate 311 is a flat plate, or an arc-shaped plate with an arc-shaped surface, the lifting plate 311 can abut against the end surface of the workpiece to be processed to form an end limit; when a clearance hole is provided on the lifting plate 311, the workpiece to be processed can pass through, thereby forming a preliminary limit on the outer edge of the workpiece to be processed.

[0082] Multiple limiting columns 312 are distributed at intervals on the lifting plate 311, which can press the workpiece to be processed from above. This structure can not only ensure the effective limitation of the workpiece to be processed, but also evenly distribute the limiting force to prevent the workpiece to be processed from shaking during the processing. At the same time, the detachable limiting columns 312 are convenient for adjustment or replacement according to different workpieces to be processed.

[0083] See also Figure 3 and Figure 4 , exemplarily, the limiting assembly 3 also includes a second stud 34 and a pressure plate 35; the second stud 34 is inserted into the fixed platform 11 or the movable platform 12, and is arranged parallel to the first stud 32; one end of the second stud 34 is connected to the lifting drive member 33; the other end of the second stud 34 extends upward from the fixed platform 11 or the movable platform 12, and is arranged lower than the limiting column 312; the pressure plate 35 is arranged at the protruding end of the second stud 34; wherein the second stud 34 and the first stud 32 rotate in opposite directions, so that the first stud 32 and the pressure plate 35 press the upper and lower sides of the workpiece to be processed up and down.

[0084] It should be understood that some parts to be processed are not of regular shape; for example, the shell structure in automobile processing parts has one side of the shell protruding upward and the other side is open. When cutting, the edge of the shell can abut against the top surface of the movable table 12 or the fixed table 11, but its internal hollow structure makes it easy to deform during cutting.

[0085] In the present application, a second stud 34 is provided in the limiting assembly 3 , so that the second stud 34 can extend upward and abut against the hollow inner side surface of the shell structure, thereby forming an effective support for the shell structure.

[0086] The second stud 34 is arranged parallel to the first stud 32 and rotates in opposite directions. The pressure plate 35 is provided at the protruding end of the second stud 34, and cooperates with the first stud 32 to press the workpiece to be processed up and down, further enhancing the fixing and supporting effect of the workpiece to be processed, preventing the workpiece to be processed from moving up and down during the processing, and improving the stability and quality of the processing.

[0087] See also Figure 4 In some embodiments, the lifting drive member 33 includes a second drive motor 331, a second gear 333 and a third gear 334; the second drive motor 331 is arranged in the fixed platform 11 or the movable platform 12, and the power output end of the second drive motor 331 is provided with a first gear 332; the second gear 333 is screwed onto the first stud 32 and meshes with the first gear 332; the third gear 334 is screwed onto the second stud 34 and meshes with the first gear 332; wherein the second drive motor 331 is used to drive the second gear 333 and the third gear 334 to rotate through the first gear 332, so that the first stud 32 and the second stud 34 rotate in opposite directions in the vertical direction.

[0088] The lifting drive member 33 drives the first gear 332 through the second driving motor 331.
