[0021] 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.

[0022] Please see Figure 1-4This utility model provides a technical solution: a cutting device for the cross section of an automotive water-cooled sealing strip, including a work cabinet 1, a pulley 2 installed at the bottom of the work cabinet 1, a cabinet door 3 installed on the surface of the work cabinet 1, a worktable 4 connected to the top of the work cabinet 1, a controller 5 connected to one end of the top of the worktable 4, a collection box 6 installed on the top of the worktable 4, a lifting cutting device 7 provided on one side of the top of the worktable 4, and a positioning feeding device 8 also provided on the top of the worktable 4.

[0023] The positioning and feeding device 8 includes a base plate 801, the bottom of which is fixedly connected to the upper surface of the worktable 4. A base 802 is connected to the top of the base plate 801, and a positioning stage 803 is mounted on the surface of the base 802. A servo motor 804 is mounted on one side of the positioning stage 803, and a screw 805 is connected to the output end of the servo motor 804. A spacer 806 is connected to the middle of the screw 805, and a slider 807 is mounted on the surface of the screw 805. A guide block 808 is connected to the bottom of the slider 807. A guide groove 809 is formed on the surface of the base 802, and a connecting rod 810 is connected to the top of the slider 807. A sliding groove 811 is formed on the upper surface of the positioning stage 803, and a clamping block 812 is connected to the top of the connecting rod 810. One end is connected to a support platform 813, and a hydraulic cylinder 814 is installed above the support platform 813. The output end of the hydraulic cylinder 814 is connected to a hydraulic rod 815, and one end of the hydraulic rod 815 is connected to a push plate 816. Through the positioning and feeding device 8, the automotive water-cooling sealing strip is placed on the positioning platform 803. At this time, the servo motor 804 starts to work. With its high-precision speed control performance, the servo motor 804 drives the screw 805 to rotate. Since there is a threaded transmission relationship between the screw 805 and the slider 807, when the screw 805 rotates, the slider 807 will move linearly along the axial direction of the screw 805. The guide block 808 at the bottom of the slider 807 cooperates with the guide groove 809 on the surface of the base 802. The guide block 808 provides precise guidance, ensuring that the slider 807 does not deviate or wobble during movement, making the movement of the slider 807 more stable and accurate. As the slider 807 moves, the connecting rod 810 connected to it also moves synchronously, thereby driving the clamping block 812 to slide in the groove 811 on the upper surface of the positioning table 803. By controlling the rotation direction and angle of the servo motor 804, the distance between the two clamping blocks 812 can be adjusted, thereby firmly clamping the sealing strips of different sizes onto the positioning table 803, completing the initial positioning of the sealing strips. After positioning is completed, the hydraulic cylinder 814 above the support table 813 starts. The hydraulic cylinder 814 drives the hydraulic rod 81 through the pressure change of the internal hydraulic oil. 5. The hydraulic cylinder 814 performs a telescopic movement. When it receives a feed command from the controller 5, the hydraulic rod 815 slowly extends, pushing the push plate 816 forward. The push plate 816 contacts the clamped and fixed sealing strip. Under the thrust of the hydraulic rod 815, the sealing strip is smoothly pushed along the cutting direction, realizing the feeding action of the sealing strip. During the feeding process, the servo motor 804 can finely adjust the rotation of the screw 805 in real time according to the cutting requirements, driving the slider 807 and the clamping block 812 to move slightly, ensuring that the sealing strip maintains a precise position during feeding. This, combined with the lifting and cutting device 7, completes high-precision cross-sectional cutting. After one cut is completed, the hydraulic cylinder 814 drives the hydraulic rod 815 to retract, and the push plate 816 resets.Waiting for the next feed command, the servo motor 804 reverses, releasing the clamping block 812, allowing the operator to easily remove the cut sealing strip and place a new sealing strip to be cut.

[0024] Furthermore, four identical sets of pulleys 2 are installed at the bottom of the work cabinet 1, symmetrically distributed in a cross shape at the four corners of the bottom of the work cabinet 1 around its central axis. The pulleys 2 greatly improve the ease of movement of the entire cutting device. In automotive production workshops, the production line layout may change due to adjustments in production needs, equipment maintenance, etc. In such cases, the four sets of pulleys symmetrically distributed in a cross shape allow workers to easily push the work cabinet 1, enabling the cutting device to quickly move to the designated position. The even and symmetrical distribution of the pulleys ensures the balance of the device during movement, preventing uneven force distribution from causing problems. The pulleys prevent the device from tilting or even tipping over, effectively protecting the components inside the work cabinet 1 and the controller 5, collection box 6, and other equipment on the workbench 4. Moreover, this design allows for smooth movement of the pulleys regardless of the floor conditions, such as common metal or cement floors in workshops. This reduces the resistance to movement, saves manpower, and minimizes wear and tear on the floor. Furthermore, when cleaning or maintenance is required, the pulleys 2 can be used to move the device to an open area, facilitating comprehensive inspection, maintenance, and repair by staff, greatly improving the efficiency of equipment maintenance.

[0025] Furthermore, the lifting and cutting device 7 includes a bracket 701, which is installed above the worktable 4. A fixed rod 702 is connected to the middle of the bracket 701. A lifting groove 703 is formed on the surface of the fixed rod 702. A rotary motor 704 is connected to the top of the fixed rod 702. A lead screw 705 is connected to the output end of the rotary motor 704. An auxiliary rod 706 is connected to the surface of the bracket 701. A lifting block 707 is connected to the surface of the lead screw 705. A balance plate 708 is connected to the outer end of the lifting block 707. A connecting frame 709 is connected to the surface of the balance plate 708. A motor housing 710 is installed on one side of the connecting frame 709. A drive motor 711 is installed inside the motor housing 710. The output end of motor 711 is connected to a cutting blade 712. Through the lifting cutting device 7, after the positioning feed device 8 fixes and pushes the sealing strip to the predetermined cutting position, the lifting cutting device 7 begins to perform the cutting action. The rotary motor 704 starts first, driving the lead screw 705 to rotate. Since the lead screw 705 and the lifting block 707 are connected by a threaded pair, the rotational motion of the lead screw 705 is converted into linear motion of the lifting block 707 along the lead screw axis. At this time, driven by the lead screw 705, the lifting block 707 performs vertical lifting motion along the lifting groove 703 on the surface of the fixed rod 702. To ensure the stability of the cutting process, a balance plate 708 and an auxiliary rod 7 are connected to the outside of the lifting block 707. 06. Sliding engagement: The auxiliary rod 706 guides and supports the balance plate 708, preventing the lifting block 707 from tilting or wobbling during movement, ensuring the precise vertical trajectory of the cutting blade 712. As the lifting block 707 descends, the connecting frame 709 carries the motor housing 710 and the cutting blade 712 downwards synchronously until the cutting blade 712 approaches the sealing strip to be cut. At this point, the drive motor 711 starts, driving the cutting blade 712 to rotate at high speed. When the cutting blade 712 contacts the surface of the sealing strip, it uses its sharp blade and the cutting force generated by high-speed rotation to cut the sealing strip cross-section. During the cutting process, the rotary motor 704 can adjust the cutting speed according to the material of the sealing strip and the cutting direction. To meet the required cutting depth, the rotation angle of the lead screw 705 is precisely controlled, thereby adjusting the descent speed and depth of the cutting blade 712 to ensure the accuracy of the cutting dimensions. After one cut is completed, the rotary motor 704 reverses, driving the lead screw 705 to rotate in the opposite direction, causing the lifting block 707 to rise and reset. At the same time, the drive motor 711 stops working, the cutting blade 712 stops rotating, and the entire lifting and cutting device 7 returns to its initial position, waiting for the next cutting command. This method of transmission via motor-driven lead screw, combined with a multi-directional balanced support structure, ensures that the cutting blade 712 maintains high stability during the lifting process, effectively improving cutting accuracy and efficiency, and meeting the high-quality cutting requirements of automotive water-cut sealing strip cross-sections.

[0026] Furthermore, the lead screw 705 drives the lifting block 707 to slide inside the lifting groove 703 via the rotary motor 704. The outer wall size of the lifting block 707 matches the inner wall size of the lifting groove 703. Through the arrangement of the lead screw 705, the lifting groove 703, and the lifting block 707, the lifting groove 703 provides a precise motion trajectory for the lifting block 707, ensuring that the lifting block 707 can only move linearly along the axis of the lead screw 705, avoiding offset and swaying during the movement, thereby ensuring the vertical lifting accuracy of the cutting blade 712. Because the lifting block 707 is tightly fitted with the inner wall of the lifting groove 703, when the lead screw 705 rotates, the lifting block 707 will not rotate with the lead screw, but will convert the rotational motion into linear motion, improving transmission efficiency and stability. The tightly fitted lifting block 707 and lifting groove 703 increase the structural rigidity of the entire lifting mechanism, which can better withstand the vibration and impact generated during the cutting process, reduce the deformation and wear of components, and extend the service life of the equipment.

[0027] Furthermore, two identical sets of auxiliary rods 706 are symmetrically distributed around the central axis of the bracket 701, and both sets of auxiliary rods 706 penetrate the balance plate 708. Through the setting of the auxiliary rods 706, the symmetrically distributed auxiliary rods 706 provide uniform support force for the balance plate 708, keeping the balance plate 708 in a horizontal state during the lifting process. This ensures the parallelism between the cutting plane of the cutting blade 712 and the cross-section of the sealing strip, improving the cutting quality. The auxiliary rods 706 and the lifting groove 703 work together to form a double guiding structure, further enhancing the stability and accuracy of the movement of the lifting block 707. Especially when cutting at high speed or cutting sealing strips made of harder materials, the auxiliary rods 706 can effectively suppress vibration and ensure the smooth progress of the cutting process. During the cutting process, the cutting blade 712 will be subjected to the reaction force from the sealing strip. The auxiliary rods 706 can distribute these forces to the bracket 701, reducing the load on the lead screw 705 and the lifting block 707, and extending the service life of key transmission components.

[0028] Furthermore, the threads of the screw 805 are symmetrically arranged around the central axis of the spacer 806. Two identical sets of sliders 807 are connected to the surfaces of the screw 805 with symmetrically distributed threads. Through the arrangement of the screw 805 and sliders 807, when the servo motor 804 drives the screw 805 to rotate, due to the symmetrical distribution of the threads, the two sliders 807 will simultaneously move towards or away from the spacer 806, achieving synchronous, opposite-direction movement of the clamping block 812. This synchronous movement ensures that the sealing strip receives uniform clamping force during positioning, avoiding deformation or displacement caused by uneven force, thus improving positioning accuracy. The symmetrical thread design ensures that the two sliders 807 maintain a symmetrical position relative to the spacer 806 during movement. Therefore, regardless of the size of the sealing strip, the clamping block 812 can automatically center it to the center of the positioning table 803 without manual adjustment, greatly improving operational efficiency.

[0029] Furthermore, the position of the guide block 808 corresponds to the position of the guide groove 809, and the outer wall dimension of the guide block 808 matches the inner wall dimension of the guide groove 809. The position of the push plate 816 corresponds to the position of the central axis of the positioning table 803. Through the arrangement of the guide block 808, the guide groove 809, and the push plate 816, the tight fit between the guide block 808 and the guide groove 809 provides precise guidance for the movement of the slider 807, ensuring that the slider 807 will not deviate or wobble during movement. This allows the clamping block 812 to be accurately positioned at the predetermined position, improving the stability of the sealing strip. Position accuracy is ensured by aligning the push plate 816 with the central axis of the positioning table 803. This ensures that the force exerted by the push plate 816 on the sealing strip is evenly distributed along the centerline of the sealing strip, preventing the sealing strip from skewing or twisting during the feeding process. This smooth feeding motion helps ensure the flatness and dimensional accuracy of the cut surface. The design of the guide block 808 and guide groove 809 makes the entire positioning and feeding device 8 more compact, reducing the space occupied by the equipment. At the same time, this design also improves the rigidity and stability of the device, enabling it to better withstand the impact force generated during the cutting process.

[0030] Working Principle: Operators can conveniently and smoothly move the device to a suitable position using the four sets of pulleys 2 arranged symmetrically in a cross shape at the bottom of the work cabinet 1, according to the workshop layout and usage requirements, to prepare for subsequent work. After preparation, the operator opens the cabinet door 3 to operate inside the work cabinet 1 or store relevant tools and spare parts. Then, the automotive water-cutting sealing strip to be cut is placed on the positioning table 803 of the positioning and feeding device 8. The servo motor 804 is started. With its high-precision speed control performance, the servo motor 804 drives the screw 805 to rotate. Based on the threaded transmission principle, the slider 807 moves linearly along the axis of the screw 805. During this process, the guide block 808 at the bottom of the slider 807 and the guide groove on the surface of the base 802... Precise coordination ensures stable and unbiased movement of slider 807. As slider 807 moves, connecting rod 810 drives clamping block 812 to slide within groove 811 above positioning table 803. By controlling the rotation direction and angle of servo motor 804, the distance between the two clamping blocks 812 is adjusted, firmly clamping sealing strips of different sizes onto positioning table 803, completing initial positioning. After positioning, controller 5 sends a feed command to hydraulic cylinder 814 above support table 813. The hydraulic oil pressure inside hydraulic cylinder 814 changes, driving hydraulic rod 815 to extend and push push plate 816 forward. Push plate 816 contacts the clamped sealing strip, smoothly pushing the sealing strip along the cutting direction, realizing the feed action. During the feed process, servo motor 804... The servo motor 804 adjusts the rotation of the screw 805 in real time according to the cutting requirements, driving the slider 807 and the clamping block 812 to move slightly, ensuring the precise position of the sealing strip during feeding. When the sealing strip is pushed to the predetermined cutting position, the lifting cutting device 7 starts working. The rotary motor 704 starts, driving the lead screw 705 to rotate. The lead screw 705 is connected to the lifting block 707 through a threaded pair, causing the lifting block 707 to move vertically up and down along the lifting groove 703 on the surface of the fixed rod 702. The balance plate 708 on the outside of the lifting block 707 slides in cooperation with two symmetrically distributed sets of auxiliary rods 706. The auxiliary rods 706 provide guidance and support, ensuring that the balance plate 708 moves horizontally, thereby ensuring that the movement trajectory of the cutting blade 712 is precisely vertical. As the lifting block 707 descends, the continuous The receiving frame 709, carrying the motor housing 710 and the cutting blade 712, synchronously moves down to near the position where the sealing strip is to be cut. At this time, the drive motor 711 starts, driving the cutting blade 712 to rotate at high speed. After the cutting blade 712 contacts the surface of the sealing strip, it uses the cutting force generated by the high-speed rotation to cut the sealing strip cross-section. During the cutting process, the rotary motor 704 precisely controls the rotation angle of the lead screw 705 according to the material of the sealing strip and the required cutting depth, adjusting the descent speed and depth of the cutting blade 712 to ensure the cutting dimensional accuracy. After one cut is completed, the rotary motor 704 reverses, driving the lead screw 705 to rotate in the opposite direction, causing the lifting block 707 to rise and reset. The drive motor 711 stops working, the cutting blade 712 stops rotating, and the lifting and cutting device 7 returns to its initial position.Hydraulic cylinder 814 drives hydraulic rod 815 to retract, push plate 816 resets, servo motor 804 reverses, releasing clamping block 812. The operator removes the cut sealing strip, places a new sealing strip to be cut, and begins the next round of cutting. Throughout the cutting process, collection box 6 collects debris generated during cutting, keeping the worktable 4 clean and preventing debris from affecting cutting accuracy and equipment operation. Controller 5 monitors and coordinates the operation of positioning feed device 8 and lifting cutting device 7 in real time, precisely controlling the actions of each component according to preset parameters and actual conditions to ensure the entire cutting process is efficient, stable, and accurate. This completes the usage process of an automotive water-cooled sealing strip section cutting device.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
