[0006] In order to achieve the above object, the utility model adopts the following technical scheme: a small machine tool for steel sheet correction, comprising:

[0007] A machining machine tool;

[0008] A grinding assembly is arranged on the inner top of the machining machine tool, the grinding assembly comprises a support frame fixed on the inner top of the machining machine tool, a first transmission motor is installed on the support frame, a ball screw is fixed on the output end of the first transmission motor, a connecting block is fixed on the ball screw, a support block is fixed on the bottom of the connecting block, a guide rod is fixed on one side of the support frame close to the ball screw, the connecting block is slidingly connected to the guide rod, a second transmission motor is installed on the support block, and a grinding cutter head is arranged on the bottom of the support block.

[0009] The positioning assembly is arranged on the inner bottom of the machining tool, and comprises a support plate fixed on the inner bottom of the machining tool, a limiting plate fixed on one side of the top of the support plate, a first fixing block fixed on the support plate, a limiting rod fixed on the first fixing block, a first limiting block slidably connected to the limiting rod, a first telescopic spring arranged on the limiting rod, a moving block slidably connected to the limiting rod, and a positioning plate fixed on the moving block.

[0010] Further, one end of the first telescopic spring is fixed on the first fixing block, and the other end of the first telescopic spring is fixed on the first limiting block.

[0011] The beneficial effect of the above further scheme is that one end of the first telescopic spring is fixed on the first fixing block, and the other end of the first telescopic spring is fixed on the first limiting block. When the moving block slides on the limiting rod, the first limiting block moves, compresses or stretches the first telescopic spring, and the elastic force of the spring provides a reverse force for the moving block, so as to ensure that the positioning plate uniformly applies pressure to the steel sheet, avoid the steel sheet from deviating during grinding, and simultaneously play a buffering and resetting role.

[0012] Further, a second fixing block is fixed on the support plate, a second limiting block is fixed on one side of the bottom of the moving block close to the second fixing block, and the second limiting block is slidably connected to the second fixing block.

[0013] The beneficial effect of the above further scheme is that the second limiting block is fixed on the bottom of the moving block and slidably connected to the second fixing block. When the moving block moves along the limiting rod, the second limiting block slides on the second fixing block, plays a role of auxiliary guide and limiting, enhances the movement stability of the moving block, prevents the moving block from tilting or shaking, and ensures the positioning accuracy of the positioning plate to the steel sheet.

[0014] Further, a third transmission motor is installed on one side of the support plate close to the moving block, and an eccentric block is fixed on the output end of the third transmission motor.

[0015] The beneficial effect of the above further scheme is that the third transmission motor is fixed on the support plate, and the output end of the third transmission motor is connected to the eccentric block. When the third transmission motor is started, the output end of the third transmission motor drives the eccentric block to rotate, so that the eccentric block can push the moving block to move.

[0016] Further, a connecting assembly is arranged on the support block, the connecting assembly comprises a screw rod fixed on the grinding cutter head, and a limiting groove is formed on one side of the support block close to the screw rod.

[0017] The beneficial effects of adopting the above-mentioned further solution are: in the connecting assembly on the support block, the grinding cutter head is connected to the support block through a screw, and the screw can slide in the limiting groove, which facilitates the installation and adjustment of the position of the grinding cutter head, while ensuring its stability during operation and ensuring that the grinding cutter head can accurately process the steel sheet.

[0018] Furthermore, a third limiting block is slidably connected to the screw, and a fourth limiting block is slidably connected to the side of the screw near the top of the third limiting block.

[0019] The beneficial effects of adopting the above-mentioned further solution are: a second telescopic spring is provided between the third and fourth limit blocks on the screw. When the grinding disc is impacted by external force, the third and fourth limit blocks slide relative to each other, compressing or stretching the second telescopic spring. The second telescopic spring plays a buffering role, protecting the grinding disc and support block, and extending the service life of the equipment.

[0020] Furthermore, a second telescopic spring is provided on the screw, one end of the second telescopic spring is fixed to the third limiting block, the other end of the second telescopic spring is fixed to the fourth limiting block, and a nut is threadedly connected to the screw near the top.

[0021] The beneficial effects of adopting the above-mentioned further solution are as follows: the nut connected by the thread at the top of the screw is used to fasten the grinding cutter head. After the grinding cutter head is installed, the nut is rotated to press down on the fourth limit block, and then the grinding cutter head is fixed by the second telescopic spring and the third limit block to prevent it from loosening during operation and ensure that the grinding work is carried out normally.

[0022] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0023] In this invention, after the machine tool is started, the steel sheet is placed on the support plate, with one side attached to the limiting plate. The moving block is pushed to slide on the limiting rod, compressing the first telescopic spring. The positioning plate is used to position and clamp the other side of the steel sheet. Subsequently, the grinding assembly starts working. The first drive motor starts, and its output end drives the ball screw to rotate. Since the connecting block is connected to the ball screw and slides on the guide rod, the connecting block will move along the direction of the guide rod, thereby driving the support block to move. At this time, the second drive motor starts, driving the grinding disc to rotate at high speed, performing precise grinding on the surface of the steel sheet, and processing the dimensional accuracy and flatness of the steel sheet, achieving high-precision and high-efficiency steel sheet correction.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] like Figures 1-4 As shown, this embodiment provides a technical solution: a small machine tool for steel sheet correction, comprising:

[0036] Machine tool 1;

[0037] Grinding assembly 2 is located inside the top of the processing machine tool 1. Grinding assembly 2 includes a support frame 21 fixed inside the top of the processing machine tool 1. A first drive motor 22 is mounted on the support frame 21. A ball screw 23 is fixed to the output end of the first drive motor 22. A connecting block 24 is fixed on the ball screw 23. A support block 25 is fixed to the bottom of the connecting block 24. A guide rod 26 is fixed on the side of the support frame 21 near the ball screw 23. The connecting block 24 is slidably connected to the guide rod 26. A second drive motor 27 is mounted on the support block 25. A grinding disc 28 is provided at the bottom of the support block 25.

[0038] Positioning component 3 is located at the inner bottom of the machining tool 1. Positioning component 3 includes a support plate 31 fixed to the inner bottom of the machining tool 1. A limit plate 32 is fixed to one side of the top of the support plate 31. A first fixing block 33 is fixed to the support plate 31, and a limit rod 34 is fixed to the first fixing block 33. A first limit block 35 is slidably connected to the limit rod 34, and a first telescopic spring 36 is provided on the limit rod 34. A moving block 37 is slidably connected to the limit rod 34, and a positioning plate 38 is fixed to the moving block 37. The operator places the steel sheet on the support plate 31, ensuring that one side of it is tightly fitted with the limit plate 32. Then, the operator pushes the moving block 37 to slide on the limit rod 34. The sliding of the moving block 37 compresses the first telescopic spring 36. The positioning plate 38 is used to position and clamp the other side of the steel sheet, ensuring the steel sheet remains stable during processing. After clamping, the grinding component 2 begins to work. First, the first transmission... When motor 22 starts, its output drives ball screw 23 to rotate. Since connecting block 24 is connected to ball screw 23 and can slide on guide rod 26, the rotation of ball screw 23 drives connecting block 24 to move along guide rod 26. The movement of connecting block 24 further drives support block 25 to make corresponding displacement. Then, second drive motor 27 starts, driving grinding disc 28 to rotate at high speed. Under the drive of support block 25, grinding disc 28 performs precise grinding along the surface of steel sheet. By controlling the operation of first drive motor 22 and second drive motor 27, grinding disc 28 can perform high-precision grinding on the surface of steel sheet, ensuring that the dimensional accuracy and flatness of steel sheet meet the requirements. This achieves high-precision and high-efficiency correction of steel sheet, which not only improves processing efficiency but also ensures the stability of processing quality. It is suitable for industrial production scenarios with high requirements for steel sheet size and flatness.

[0039] The above solutions still have the problem that, when the steel sheet needs to be adjusted, they cannot prevent it from loosening during operation and ensure the normal operation of the grinding process. Figures 3-4As shown: One end of the first telescopic spring 36 is fixed to the first fixed block 33, and the other end of the first telescopic spring 36 is fixed to the first limiting block 35. When the moving block 37 slides on the limiting rod 34, the first limiting block 35 moves accordingly, compressing or stretching the first telescopic spring 36. The elastic force of the spring provides a reverse force to the moving block 37, ensuring that the positioning plate 38 applies uniform pressure to the steel sheet, preventing the steel sheet from shifting during grinding, and also playing a role in buffering and resetting. A second fixed block 39 is fixed on the support plate 31, and a second limiting block 310 is fixed to the bottom of the moving block 37 near the second fixed block 39. The second limiting block 310 is slidably connected to the second fixed block. On the second fixed block 39, the second limiting block 310 is fixed to the bottom of the moving block 37 and slidably connected to the second fixed block 39. When the moving block 37 moves along the limiting rod 34, the second limiting block 310 slides on the second fixed block 39, which plays the role of auxiliary guidance and limiting, enhancing the movement stability of the moving block 37, preventing it from tilting or shaking, and ensuring the positioning accuracy of the positioning plate 38 on the steel sheet. A third drive motor 311 is installed on the side of the support plate 31 near the moving block 37. An eccentric block 312 is fixed to the output end of the third drive motor 311. The third drive motor 311 is fixed on the support plate 31, and its output end is connected to the eccentric block 312. When the third drive motor 311 starts, its output end drives the eccentric block 312 to rotate, so that the eccentric block 312 can push the moving block 37 to move.

[0040] like Figure 2 as well as Figure 5As shown, a connecting component 4 is provided on the support block 25. The connecting component 4 includes a screw 41 fixed on the grinding disc 28. A limiting groove 42 is provided on the side of the support block 25 near the screw 41. In the connecting component 4 on the support block 25, the grinding disc 28 is connected to the support block 25 through the screw 41. The screw 41 can slide in the limiting groove 42, which facilitates the installation and adjustment of the position of the grinding disc 28, and at the same time ensures its stability during operation, ensuring that the grinding disc 28 can accurately process the steel sheet. A third limiting block 43 is slidably connected to the screw 41, and a fourth limiting block 44 is slidably connected to the side of the screw 41 near the top of the third limiting block 43. A second telescopic spring 45 is provided between the third limiting block 43 and the fourth limiting block 44 on the screw 41. When the grinding disc 28 is impacted by an external force, the third limiting block 45... The positioning block 43 and the fourth limiting block 44 slide relative to each other, compressing or stretching the second telescopic spring 45. The second telescopic spring 45 acts as a buffer, protecting the grinding disc 28 and the support block 25, and extending the service life of the equipment. The screw 41 is equipped with the second telescopic spring 45. One end of the second telescopic spring 45 is fixed to the third limiting block 43, and the other end of the second telescopic spring 45 is fixed to the fourth limiting block 44. A nut 46 is threaded on the side of the screw 41 near the top. The nut 46 threaded on the top of the screw 41 is used to fasten the grinding disc 28. After the grinding disc 28 is installed, the nut 46 is rotated to press down on the fourth limiting block 44, thereby fixing the grinding disc 28 through the second telescopic spring 45 and the third limiting block 43, preventing it from loosening during operation, and ensuring the normal operation of the grinding work.

[0041] Working principle:

[0042] like Figures 1-5As shown, firstly, the operator places the steel sheet on the support plate 31 at the bottom of the processing machine tool 1, ensuring that one side of it is tightly fitted against the limiting plate 32. Then, the third drive motor 311 on the support plate 31 is activated. The eccentric block 312 at its output end rotates, pushing the moving block 37 to slide on the limiting rod 34. The moving block 37 compresses the first telescopic spring 36, causing the positioning plate 38 to clamp and position the other side of the steel sheet, ensuring its stability. Simultaneously, the second limiting block 310 at the bottom of the moving block 37 slides on the second fixed block 39, assisting in guiding and limiting the position, enhancing stability. Positioning is complete, and the grinding assembly 2 begins operation. The first drive motor 22 starts, and its output end drives the ball screw 23 to rotate. Because the connecting block 24 is connected to the ball screw 23 and can slide on the guide rod 26, the connecting block 24 moves along the direction of the guide rod 26. The movement of the support block 25 causes the second drive motor 27 to start, driving the grinding disc 28 to rotate at high speed. The support block 25 drives the grinding disc 28 to grind the steel sheet. The connecting component 4 ensures the stable operation of the grinding disc 28. The grinding disc 28 is connected to the support block 25 through the screw 41. The screw 41 can slide in the limiting groove 42 for easy installation and position adjustment. When the grinding disc 28 is impacted by external force, the third limiting block 43 and the fourth limiting block 44 on the screw 41 slide relative to each other, compressing or stretching the second telescopic spring 45 to provide buffer protection. During installation, the rotating nut 46 presses down on the fourth limiting block 44, and the grinding disc 28 is fixed by the second telescopic spring 45 and the third limiting block 43 to prevent loosening, ensuring high-precision grinding and meeting the high requirements of industrial production for the size and flatness of steel sheets.

[0043] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
