[0022] 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.

[0023] Please see Figure 1-4An embodiment of this utility model provides a casing sawing device with a guiding structure, comprising a support column 2, with sliding sleeves 8 sleeved on the outside of each support column 2, and a sawing machine 10 fixedly assembled between the sliding sleeves 8. A base 14 is fixedly connected between the support columns 2, and a turntable 15 is movably connected inside the base 14. A cutting table 13 is rotatably connected to the top of the turntable 15. A guiding structure is installed inside the base 14. The guiding structure includes a rotating rod 17 movably assembled inside the rear end of the base 14, with first gears 18 fixedly sleeved on both sides of the rotating rod 17. The front ends of the first gears 18 are meshed with second gears 19, and the front ends of the second gears 19 are fixedly... A ball screw 20 is fixedly connected to the base 14. The ball screw 20 is arranged on both sides of the base 14 along the length direction of the base 14. Each ball screw 20 is fitted with a screw sleeve 21. The top of the screw sleeve 21 is fixedly connected to the turntable 15. A feeding motor 16 is fixedly connected to the rear end of the base 14. The output shaft of the feeding motor 16 is fixedly connected to the rotating rod 17. A receiver 23 is set between the ball screws 20. Four sets of position sensors 22 are set at the bottom of the cutting table 13. Two sets of parallel guide rails 24 are fixedly fixed at the bottom of the base 14. Two sets of guide sleeves 25 are fixedly fixed at the bottom of the turntable 15. The guide sleeves 25 are respectively embedded in the outside of the guide rails 24 and slide.

[0024] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, the cutting table 13 moves back and forth within the base 14 via the turntable 15 to facilitate access to the cutting area below the sawing machine 10. The feed motor 16, a model MG90-30-200S servo motor, is installed at the rear end of the base 14 and features speed reduction and high-resolution encoder feedback. Its output shaft is fixedly connected to the rotating rod 17. The rotating rod 17 drives the first gear 18 to rotate, and the first gear 18 meshes with the second gear 19, driving the ball screw 20 to rotate synchronously. This causes the screw sleeve 21 to move axially on the ball screw 20. The top of the screw sleeve 21 is fixedly connected to the turntable 15, thereby driving the turntable. The turntable 15 moves precisely along the base 14. During the movement, the position sensor 22 continuously transmits infrared signals to the receiver 23. The position sensor 22 is model E3Z-R61, which realizes dynamic identification and feedback correction of the housing position to prevent cutting errors. During the movement, two sets of guide sleeves 25 set at the bottom of the turntable 15 are respectively fitted onto the guide rails 24 in the base 14, which can provide precise support and direction limiting function in the entire reciprocating guidance. A control device 12 is installed on the left side of the support column 2. The control device 12 is a PLC controller, which is used to control the opening and closing of various electrical components and set parameters.

[0025] The turntable 15 has a built-in steering motor, and the position sensors 22 are distributed in a ring around the center point of the turntable 15. The top of the cutting table 13 is fixed with four sets of cylinders 26. The piston rod of each set of feeding cylinders 26 is fixedly connected to a clamping plate 11. The clamping plates 11 are arranged on the surface of the cutting table 13 to form a four-way clamping.

[0026] Specifically, such as Figure 1 and Figure 4 As shown, the turntable 15 has a built-in steering motor, which is a closed-loop stepper motor of model TSM11-3NM12. It has microstepping drive and encoder feedback control functions. It can achieve precise closed-loop control of the angle of the cutting table 13 through the output signal of the control device 12. It can drive the cutting table 13 to rotate and adjust along the horizontal angle to cooperate with the sawing machine 10 to perform cutting processes in multiple directions. Four sets of clamping plates 11 are installed on the surface of the cutting table 13. The four sets of clamping plates 11 are distributed in a ring with the center point of the cutting table 13 as the symmetrical point. They are used to synchronously clamp and position the machine shell to be cut from four directions to prevent displacement during the cutting process. Each set of clamping plates 11 is driven by a matching thin cylinder 26, model MGPM16-25Z. The clamping process of the clamping plates 11 can be operated independently or in conjunction according to the instructions of the control device 12 to achieve stable clamping and precise alignment. Flexible anti-slip pads can be set on the inner wall of the clamping plates 11 to effectively prevent surface damage while ensuring stable positioning of the machine shell.

[0027] A lifting motor 1 is fixedly connected to the left side of the support column 2. A screw 4 is fixedly connected to the output shaft of the lifting motor 1. Threaded blocks 5 are respectively sleeved on both sides of the screw 4. Hangers 6 are respectively hinged to the bottom of the threaded blocks 5 and the top of the sawing machine 10. The screw 4 is located below the top plate 3. A reserved groove is machined on the surface of the top plate 3. The threaded blocks 5 are embedded in the reserved groove and move linearly. An inner groove 9 is opened in the support column 2 along its height direction. A spring 7 is fixed at the top of the inner groove 9.

[0028] Specifically, such as Figure 1 and Figure 3 As shown, the sawing machine 10 is equipped with a dedicated cutting motor. This motor drives the saw blade to rotate at high speed, enabling operations such as grooving and cutting of the machine casing. The sawing machine 10 is connected to the threaded block 5 via a screw 4 mechanism. The lower end of the screw 4 is driven by a lifting motor 1, which is an MG90-30-200S servo motor with a built-in gear reduction structure and rotary encoder. The speed and direction are controlled by the control device 12, causing the screw 4 to drive the threaded block 5 to move up and down, thereby pushing the sawing machine 10 to achieve vertical lifting. During the lifting and lowering process, a sliding sleeve 8 is fitted on the outside of the sawing machine 10. The sliding sleeve 8 slides with the inner groove 9 on the support column 2 to keep the sawing machine 10 moving smoothly in the vertical direction during the lifting and lowering process and prevent it from tilting. When the sawing machine 10 completes the cutting and returns to the top, the sliding sleeve 8 returns to the spring 7 at the top of the support column 2 to prevent the sawing machine 10 from hitting the end of the support column 2. The guide sleeve 25 is fitted on the guide rail 24 to provide directional limitation and support for sliding, so that the entire lifting, cutting and resetting process has good guidance and anti-deviation performance.

[0029] The computer software involved in the control device 12 carrier in the technical solution is software technology known to those skilled in the art; it is merely applied to the aforementioned hardware carrier. In other words, the computer software portion of the technical solution is an essential technical feature for solving the aforementioned technical problem, constituting a necessary technical feature for the technical problem solved by this application, but it is not a differentiating technical feature or a point of technical improvement. The applicant has not made any technical improvements to the computer software portion involved in the aforementioned related hardware carrier, nor is it a key technical point of the invention.

[0030] Therefore, it can be seen that the "lifting motor 1", "sawing machine 10", "feeding motor 16", "position sensor 22", "cylinder 26" and other components involved in this application are all physical functional modules that combine computer software programs or protocols in the prior art with the hardware carrier of this application. The computer software programs involved in these physical functional modules are all technologies known to those skilled in the art and are not improvements of this application. The improvement of this application should be the interaction relationship between the various physical functional modules, that is, the improvement of the overall structure of this application, in order to solve the corresponding technical problems to be solved by this application.

[0031] Working principle: The control device 12 starts the feeding motor 16, which drives the rotating rod 17 to rotate. The first gear 18 and the second gear 19 on the rotating rod 17 mesh and connect, driving the ball screw 20 to rotate. The screw sleeve 21 moves back and forth along the screw direction, thereby driving the turntable 15 fixed on the screw sleeve 21 to complete the guided movement within the base 14, so that the cutting table 13 can accurately enter the designated position below the sawing machine 10. During the movement, the position sensor 22 continuously cooperates with the receiver 23 to detect the real-time position of the cutting table 13 to ensure accurate stroke. When the cutting table 13 moves to the designated position, the control device 12 starts the lifting motor 1, which drives the screw 4 to rotate, causing the threaded block 5 to move up and down, thereby enabling the sawing machine 10 connected to it to achieve vertical lifting. The sawing machine 10 is fitted with a sliding sleeve 8, which slides in the inner groove 9 on the support column 2 to maintain the overall lifting stability and avoid shaking or tilting. When the sawing machine 10 completes the downward pressing... When the workpiece approaches the surface, the clamping plates 11 move. The four sets of clamping plates 11 are pushed synchronously by the cylinders 26 to clamp the machine housing from four directions, ensuring that the workpiece does not shake or deviate during the cutting process. When the sawing begins, the high-speed rotating motor inside the sawing machine 10 starts, driving the saw blade to complete the cutting of the machine housing. During this period, a chip suction device can be connected externally as needed to remove the generated metal chips through the suction port below the cutting area to prevent the accumulation of residue from interfering with the cutting path. After the cutting is completed, the lifting motor 1 reverses, causing the sawing machine 10 to rise and return to the initial position. When the sliding sleeve 8 rises to the top of the support column 2, it abuts against the buffer spring 7 to play a shock absorption and protection role. At the same time, the control device 12 controls the feeding motor 16 to make the ball screw 20 rotate in the opposite direction. The cutting table 13 moves backward with the turntable 15, exiting the cutting area and preparing for the next round of workpiece feeding and cutting operations. Throughout the working process, the guide rail 24 and the guide sleeve 25 provide stable support and limit guidance for the forward and backward movement of the turntable 15 and the cutting table 13.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
