Description

Technical Field

[0001] This application relates to the field of sealing strip processing technology, and in particular to an ultrasonic irregular cutting and drilling device for automotive sealing strips. Background Technology

[0002] The hood sealing strip is a sealing strip embedded in the side panel of the hood. It must not only ensure a tight seal but also withstand the impact when the hood is closed. Therefore, it needs to be both elastic and resilient. It mainly consists of a dense rubber matrix and a sponge tube. During processing, the sponge tube at the end of the hood sealing strip needs to be cut because different shapes are used in different locations. Traditionally, the sponge tube at the end of the sealing strip is cut manually. However, manual cutting can result in slanted cuts, requiring repeated trimming, which is time-consuming and poses safety hazards. Therefore, this invention proposes a processing device for the notch in the sponge tube at the end of the hood sealing strip to solve the problems existing in the prior art. Utility Model Content

[0003] In order to overcome the problems existing in the prior art, this application provides an ultrasonic irregular cutting and drilling device for automotive sealing strips.

[0004] The ultrasonic irregular-shaped cutting and drilling device for automotive sealing strips provided in this application adopts the following technical solution:

[0005] An ultrasonic irregular-shaped cutting and drilling device for automotive sealing strips includes a frame. A mounting plate fixed on the frame has a support plate for holding the automotive sealing strip to be cut and drilled. A clamping mechanism for holding the automotive sealing strip on the support plate is installed at the bottom of the mounting plate. The frame also has an end-cutting mechanism and a drilling mechanism. The end-cutting mechanism is located at both ends of the support plate and can move along the length of the support plate. The drilling mechanism is lifted and installed above the support plate. The end-cutting mechanism, distributed at both ends of the support plate, includes a cutting component slide plate and an angle adjustment component mounted thereon. The component slide plate is slidably mounted on a slide rail on the frame via a slider at its bottom. An ultrasonic cutting component is mounted at the end of the angle adjustment component. The drilling mechanism includes a lifting plate and a lifting guide rail located on the back of the lifting plate. A lifting cylinder is mounted on the frame to drive the lifting plate to move up and down on the lifting guide rail. An electric drill and a pneumatic drill are mounted on the front of the lifting plate along its length. The clamping mechanism includes a driving cylinder located at the bottom of the mounting plate. A locking plate is mounted on the output end of the driving cylinder. The locking plate is located on the outside of the material support plate, and a clamping plate for clamping the automotive sealing strip on the material support plate is mounted on the top of the locking plate.

[0006] By adopting the above technical solution, the automotive sealing strip to be cut and drilled is placed on the support plate. The drive cylinder of the clamping mechanism is activated, and the output end of the drive cylinder pushes the locking plate to move, so that the clamping plate on top of the locking plate located on the outside of the support plate clamps and fixes the sealing strip. Then, the end cutting mechanism starts to work. The cutting component slide plates distributed at both ends move along the frame slide rail in the length direction of the placement seat via the bottom slider. After adjusting to the required position, the corresponding blade cavity is installed according to the required cutting angle of the automotive sealing strip end. The angle adjustment component moves to adjust the angle of the ultrasonic cutting component. The ultrasonic cutting assembly then performs irregular-shaped cutting on both ends of the automotive sealing strip. Simultaneously or after the end cutting, the lifting cylinder of the drilling mechanism drives the lifting plate to descend along the lifting guide rail, causing the electric drill and air drill mounted on the front of the lifting plate along the length direction to move to the position corresponding to the position of the automotive sealing strip to be drilled on the support plate. The electric drill and air drill then start drilling the sealing strip. Throughout the process, all mechanisms work together, and the clamping mechanism ensures accurate positioning of the sealing strip. The end cutting mechanism and the drilling mechanism complete the corresponding processing steps in sequence, realizing automated irregular-shaped cutting and drilling of the automotive sealing strip.

[0007] Preferably, the angle adjustment assembly includes a bracket mounted on the cutting assembly slide plate, wherein the bracket is connected to the ultrasonic cutting assembly in sequence via a horizontal adjustment assembly and a vertical adjustment assembly. The horizontal adjustment assembly includes a first fixing plate and a first dial, and the horizontal adjustment assembly is connected to the bracket via the first fixing plate. The vertical adjustment assembly includes a second fixing plate and a second dial, and the vertical adjustment assembly is connected to the first dial via the second fixing plate, and the second dial is connected to the ultrasonic cutting assembly.

[0008] Preferably, the first fixing plate and the second fixing plate have the same structure, both including an arc-shaped adjustment groove and a rotating hole set at the center of the arc-shaped adjustment groove, wherein the scale lines on the first scale and the second scale are located on the side of the arc-shaped groove away from the rotating hole, and the first scale and the second scale are also equipped with a locking limit valve that penetrates the arc-shaped adjustment groove and a rotating shaft that penetrates the rotating hole.

[0009] Preferably, the output end of the ultrasonic cutting component extends through the blade chambers on both sides of the placement seat, wherein an automotive sealing strip guide groove is also installed at the entrance of the blade chamber, and the bottom of the blade chamber is connected to the receiving chamber through a guide drop groove.

[0010] Preferably, the bracket is also equipped with an alcohol gas hose assembly, which is used to connect an external alcohol container and to the alcohol nozzle at the knife cavity of the car's sealing strip via a pipe.

[0011] Preferably, a product positioning component is also installed on the cutting component slide plate at one end of the material support plate, including a positioning cylinder and a first guide cavity installed on the output shaft of the positioning cylinder. The mounting bracket at the bottom of the first guide cavity is slidably installed on the top of the positioning cylinder along the output shaft direction, and a second guide cavity is also fixedly installed on the positioning cylinder. The automotive sealing strip passes through the first guide cavity and the second guide cavity in sequence. The end face of the first guide cavity is in contact with the contact surface of the blade cavity, and both the first guide cavity and the blade cavity can be detachably installed on the cutting component slide plate.

[0012] By adopting the above technical solution, when performing irregular cutting and drilling of automotive sealing strips, the sealing strip is first placed on the support plate, and the drive cylinder of the clamping mechanism pushes the locking plate and clamping plate to fix the automotive sealing strip. Next, in the end cutting mechanism, the cutting component slide plate moves along the slide rail to a suitable position. The angle adjustment component, through the horizontal and vertical adjustment components on the bracket, uses the first fixed plate, the first scale, the second fixed plate, the second scale, the locking limit valve, and the rotating shaft. The first fixed plate rotates along the first scale, and during the adjustment, the locking limit valve moves along the arc-shaped adjustment groove. The scale line on the first scale can display the angle of rotation adjustment. After the adjustment is completed, the relative position of the first scale and the first fixed plate is fixed by the locking limit valve. Similarly, the relative position between the second scale and the second fixed plate is adjusted in the same way, thereby adjusting the horizontal and vertical angles of the ultrasonic cutting component to achieve precise positioning. The positioning cylinder of the product positioning component moves the first guide cavity, causing its end face to align with the cutting cavity. Simultaneously, the sealing strip passes through the first and second guide cavities to complete its positioning. Subsequently, the output end of the ultrasonic cutting component passes through the cutting cavity and, guided by the sealing strip guide groove, performs irregular cutting on both ends of the sealing strip. Waste material falls into the receiving cavity through the guide discharge groove. An alcohol container connected to the alcohol pipe assembly sprays alcohol into the cutting cavity through a pipe and an alcohol nozzle, assisting in cutting and cleaning. Simultaneously or after the end cutting, the lifting cylinder of the drilling mechanism drives the lifting plate to descend, and an electric drill and a pneumatic drill complete the drilling process on the sealing strip. The entire process, through the coordinated operation of all components, achieves efficient and precise processing of the sealing strip.

[0013] Preferably, both the air drill and the electric drill are clamped and fixed on the connecting plate by the upper clamping plate and the lower clamping plate. The inner side of the connecting plate is slidably mounted on the slide rail distributed along the length direction of the lifting plate by the slider, and the side of the connecting plate is fixedly connected to the drill bit fixing block by the support block.

[0014] Preferably, the air drill has two sets between the upper and lower clamping plates of a single set, and the electric drill has one set between the upper and lower clamping plates of a single set, and both the air drill and the electric drill are equipped with baffle separators at their output ends.

[0015] By adopting the above technical solution, after clamping and fixing the automotive sealing strip and cutting its ends, the drilling process begins. The air drill and electric drill are securely clamped to the connecting plate via upper and lower clamping plates, respectively. Each set of clamping plates houses two sets of air drills and one set of electric drills, all with baffle separators installed at their output ends. The slider on the inner side of the connecting plate slides along the guide rail along the length of the lifting plate, and its side is connected to the drill bit fixing block via a support block, allowing for flexible position adjustment. When the lifting cylinder of the drilling mechanism drives the lifting plate to descend along the lifting guide rail, the air drill and electric drill move with the connecting plate to the position on the material support plate corresponding to the drilling location of the sealing strip. After precise positioning, the air drill and electric drill start, using the baffle separators to prevent debris from flying, efficiently drilling the sealing strip. This installation and operation method ensures stable operation of various types of drill bits, achieving high-quality completion of the sealing strip drilling process.

[0016] Preferably, a guide mechanism is also installed on the clamping plate of the clamping mechanism, and the guide mechanism is located on both sides of the drive cylinder. The guide mechanism includes a guide block fixed to the bottom of the mounting plate and a moving block fixedly connected to the clamping plate. A guide rod fixedly installed on the moving block passes through the guide block, and a return spring is fitted on the guide rod between the moving block and the guide rod. The bottom of the moving block moves on the slide rail on the frame by a slider, wherein the slide rail and the guide rod are perpendicular to the length direction of the mounting plate.

[0017] By adopting the above technical solution, when processing automotive sealing strips, after placing the sealing strip on the support plate, the drive cylinder of the clamping mechanism is activated. The output end of the drive cylinder pushes the locking plate and clamping plate to move towards the sealing strip. At this time, the guide mechanism on the clamping plate on both sides of the drive cylinder works in coordination. The moving block moves with the clamping plate, and the guide rod fixed on the moving block passes through the guide block. At the same time, the slider at the bottom of the moving block slides along the slide rail on the frame perpendicular to the length of the mounting plate, ensuring the smoothness and accuracy of the clamping plate movement. During the movement, the return spring between the guide rod and the moving block is compressed. After the clamping plate firmly clamps the sealing strip, the drive cylinder maintains pressure. After processing is completed, the drive cylinder retracts, and under the elastic force of the return spring, the moving block drives the clamping plate to return along the slide rail and guide rod, releasing the sealing strip. The entire process ensures the stable operation of the clamping mechanism through the guide mechanism, providing a reliable positioning basis for the precise cutting and drilling of the sealing strip.

[0018] Preferably, an electrical box is also installed at the bottom of the rack, which is connected to the signal display screen on the side of the rack. Protective nets are installed on the sides and back of the rack, and lighting is installed on the top of the rack.

[0019] By adopting the above technical solution, the electrical box at the bottom of the frame serves as the control core, integrating and processing the power and signals of each mechanism. Through signal connection with the display screen on the side of the frame, it displays real-time information such as the equipment's operating parameters and working status, facilitating monitoring and parameter adjustment by operators. Protective nets installed on the sides and back of the frame effectively block flying debris generated during processing, ensuring operator safety and preventing external debris from affecting equipment operation. Before starting the equipment, operators can preset processing parameters on the display screen. After receiving the command, the electrical box controls the clamping mechanism to tighten the sealing strip, and the end-cutting and drilling mechanisms execute the processing tasks sequentially. Throughout the processing, the lighting on the top of the frame continuously provides sufficient illumination, ensuring operators can clearly observe the processing of the sealing strip and the operational details of the equipment, enabling timely detection and handling of abnormalities and ensuring efficient, safe, and stable processing.

[0020] In summary, this application includes at least one of the following beneficial technical effects:

[0021] 1. This application achieves precise positioning and stable clamping of automotive sealing strips by using a material support plate mounted on a frame in conjunction with a clamping mechanism. The drive cylinder moves the locking plate and clamping plate, firmly fixing the sealing strip and preventing dimensional deviations caused by strip displacement during processing, significantly improving processing accuracy. Simultaneously, the guiding mechanism on the clamping plate, through the cooperation of guide blocks, moving blocks, guide rods, and return springs, further enhances clamping stability, ensuring the sealing strip maintains a fixed posture during cutting and drilling, reducing scrap rates and improving product consistency.

[0022] 2. This application integrates the end-cutting mechanism and the drilling mechanism into the same equipment. The end-cutting mechanism can move along the length of the placement seat, and the drilling mechanism can be raised and lowered under the drive of the lifting cylinder. This allows multiple processes such as cutting and drilling of the sealing strip to be completed continuously on the same equipment without the need to transfer workpieces between different equipment, effectively reducing processing auxiliary time and meeting the needs of mass production. The combination of air drill and electric drill can be flexibly selected according to different processing requirements, further improving drilling efficiency.

[0023] 3. The design of the angle adjustment component in this application, through the first and second scales in the horizontal and vertical adjustment components, as well as the arc-shaped adjustment groove and rotating hole, enables the ultrasonic cutting component to be adjusted at multiple angles in the horizontal and vertical directions, thereby meeting the needs of different angles for irregular cutting of automotive sealing strips, greatly enhancing the applicability and versatility of the equipment, and can be widely used in the processing of sealing strips of various models and specifications.

[0024] 4. This application connects the output end of the ultrasonic cutting component with the blade cavity, guide chute, and receiving cavity, enabling timely discharge of waste materials after cutting and preventing waste accumulation from affecting the processing. The alcohol gas pipe component is connected to an external alcohol container, and the blade cavity is cleaned through the alcohol nozzle, which can effectively prevent processing debris residue, maintain the sharpness of the blade and the cleanliness of the processing environment, reduce the frequency of equipment maintenance, and ensure the continuity and stability of processing.

[0025] 5. This application achieves rapid and accurate positioning of automotive sealing strips through the setting of product positioning components, including positioning cylinders, first guide chambers, and second guide chambers, ensuring accurate cutting and drilling positions; and the first guide chamber and the cutting chamber can be detachably installed on the cutting component slide plate, which facilitates quick replacement of corresponding parts when processing sealing strips of different specifications, improving production flexibility and reducing equipment adjustment time and costs;

[0026] 6. This application connects the electrical box installed at the bottom of the frame to the display screen, facilitating real-time monitoring of the equipment's operating status and processing parameters by operators, thus enabling intelligent operation. The protective netting design on the sides and back of the frame effectively prevents debris from flying and injuring people during processing, ensuring operator safety. The lighting installed at the top provides ample light to the processing area, allowing operators to observe processing details and further improving processing quality and user experience.

[0035] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0036] This application discloses an ultrasonic irregular-shaped cutting and drilling device for automotive sealing strips.

[0037] Reference Figures 1-7An ultrasonic irregular-shaped cutting and drilling device for automotive sealing strips includes a frame 1. A mounting plate 11 fixed on the frame 1 has a support plate 2 for placing automotive sealing strips 3 to be cut and drilled. A clamping mechanism 4 for clamping the automotive sealing strips 3 on the support plate 2 is installed at the bottom of the mounting plate 11. An end-cutting mechanism 5 and a drilling mechanism 6 are also installed on the frame 1. The end-cutting mechanism 5 is located at both ends of the support plate 2 and can move along the length of the support plate 2. The drilling mechanism 6 is lifted and installed above the support plate 2. The end-cutting mechanism 5 is distributed at both ends of the support plate 2 and includes a cutting component slide plate 51 and an angle adjustment component 52 installed thereon. The cutting component slide plate 51 is connected to the support plate 2 by its angle adjustment component 52. The bottom slider is slidably mounted on the slide rail on the frame 1, and the end of the angle adjustment component 52 is equipped with an ultrasonic cutting component 53; the drilling mechanism 6 includes a lifting plate 61 and a lifting guide rail 62 located on the back of the lifting plate 61, and a lifting cylinder 63 is mounted on the frame 1 to drive the lifting plate 61 to move up and down on the lifting guide rail 62, wherein an electric drill 64 and a pneumatic drill 65 are mounted on the front of the lifting plate 61 along its length; the clamping mechanism 4 includes a driving cylinder 41 located at the bottom of the mounting plate 11, and a locking plate 42 is mounted on the output end of the driving cylinder 41. The locking plate 42 is located on the outside of the material support plate 2, and a clamping plate 43 for clamping the automotive sealing strip 3 on the material support plate 2 is mounted on the top of the locking plate 42. The automotive sealing strip 3 to be cut and drilled is placed on the support plate 2. The drive cylinder 41 of the clamping mechanism 4 is activated, and the output end of the drive cylinder 41 pushes the locking plate 42 to move, so that the clamping plate 43 on top of the locking plate 42 located on the outside of the support plate 2 clamps and fixes the sealing strip. Then, the end cutting mechanism 5 starts to work. The cutting component slide plates 51 distributed at both ends move along the slide rail of the frame 1 in the length direction of the placement seat via the bottom slider. After adjusting to the required position, the corresponding blade cavity 531 is installed according to the required cutting angle of the end of the automotive sealing strip 3. The angle adjustment component 52 is activated to adjust the angle of the ultrasonic cutting component 53, and then the ultrasonic cutting begins. The cutting component 53 performs irregular cutting on both ends of the automotive sealing strip 3; simultaneously or after the end cutting, the lifting cylinder 63 of the drilling mechanism 6 drives the lifting plate 61 to descend along the lifting guide rail 62, so that the electric drill 64 and air drill 65 installed on the front of the lifting plate 61 along the length direction move to the position corresponding to the position to be drilled on the automotive sealing strip 3 on the material support plate 2, and the electric drill 64 and air drill 65 start drilling the sealing strip; throughout the process, the various mechanisms work together, and the clamping mechanism 4 ensures accurate positioning of the sealing strip, and the end cutting mechanism 5 and the drilling mechanism 6 complete the corresponding processing steps in sequence, realizing the automated irregular cutting and drilling of the automotive sealing strip 3.

[0038] Reference Figures 1-7The angle adjustment component 52 includes a bracket 521 mounted on the cutting component slide plate 51. The bracket 521 is connected to the ultrasonic cutting component 53 via a horizontal adjustment component 522 and a vertical adjustment component 523 in sequence. The horizontal adjustment component 522 includes a first fixing plate 5221 and a first dial 5222. The horizontal adjustment component 522 is connected to the bracket 521 via the first fixing plate 5221. The vertical adjustment component 523 includes a second fixing plate 5231 and a second dial 5232. The vertical adjustment component 523 is connected to the first dial 5222 via the second fixing plate 5231, and the second dial 5232 is connected to the ultrasonic cutting component 53. The first fixing plate 5221 and the second fixing plate 5231 have the same structure, both including an arc-shaped adjustment groove 54 and a rotating hole 55 located at the center of the arc-shaped adjustment groove 54. The scale lines 56 on the first scale 5222 and the second scale 5232 are located on the side of the arc-shaped groove away from the rotating hole 55. The first scale 5222 and the second scale 5232 are also equipped with a locking limit valve 57 that penetrates the arc-shaped adjustment groove 54 and a rotating shaft 58 that penetrates the rotating hole 55. The output end of the ultrasonic cutting assembly 53 penetrates the blade chambers 531 on both sides of the placement seat. The inlet of the blade chamber 531 is also equipped with a guide groove 532 for the automotive sealing strip 3. The bottom of the blade chamber 531 is connected to the receiving chamber 534 through a guide drop groove 533. An alcohol gas pipe assembly 5211 is also installed on the bracket 521. The alcohol gas pipe assembly 5211 is used to connect an external alcohol container and is connected to the alcohol nozzle 5212 at the blade chamber 531 of the automotive sealing strip 3 through a pipe. A product positioning component 511 is also installed on the cutting component slide plate 51 at one end of the material support plate 2. This component includes a positioning cylinder 5111 and a first guide cavity 5112 mounted on the output shaft of the positioning cylinder 5111. A mounting bracket 5113 at the bottom of the first guide cavity 5112 is slidably mounted on the top of the positioning cylinder 5111 along the output shaft direction. A second guide cavity 5114 is also fixedly mounted on the positioning cylinder 5111. The automotive sealing strip 3 passes through the first guide cavity 5112 and the second guide cavity 5114 in sequence. The end face of the first guide cavity 5112 is in contact with the contact surface of the blade cavity 531. Both the first guide cavity 5112 and the blade cavity 531 can be detachably mounted on the cutting component slide plate 51. When performing irregular cutting and drilling of the automotive sealing strip 3, the sealing strip is first placed on the material support plate 2. The drive cylinder 41 of the clamping mechanism 4 pushes the locking plate 42 and the clamping plate 43 to fix the automotive sealing strip 3.Next, in the end-cutting mechanism 5, the cutting component slide plate 51 moves along the slide rail to a suitable position. The angle adjustment component 52, through the horizontal and vertical adjustment components 523 on the bracket 521, utilizes the first fixed plate 5221, the first scale 5222, the second fixed plate 5231, the second scale 5232, the locking limit valve 57, and the rotating shaft 58. The first fixed plate 5221 rotates along the first scale 5222 for adjustment. During the adjustment process, the locking limit valve 57 moves along the arc-shaped adjustment groove 54. The scale line 56 on the first scale 5222 can display the angle of rotation adjustment. After the adjustment is completed, the relative position of the first scale 5222 and the first fixed plate 5221 is fixed by the locking limit valve 57. Similarly, the relative position between the second scale 5232 and the second fixed plate 5231 is adjusted in the same way, thereby adjusting the horizontal and vertical angles of the ultrasonic cutting component 53 and achieving precise positioning. The positioning cylinder 5111 of the product positioning component 511 pushes the first guide cavity 5112 to move, so that the end face of the first guide cavity 5112 fits against the cutting cavity 531. At the same time, the sealing strip passes through the first guide cavity 5112 and the second guide cavity 5114 in sequence to complete the positioning. Subsequently, the output end of the ultrasonic cutting component 53 passes through the cutting cavity 531 and, guided by the sealing strip guide groove 532, performs irregular cutting on both ends of the sealing strip. The waste material falls into the receiving cavity 534 through the guide drop groove 533. The alcohol gas pipe component 5211 is connected to an alcohol container, and alcohol is sprayed into the cutting cavity 531 through the pipe and the alcohol nozzle 5212 to assist cutting and cleaning. At the same time or after the end cutting, the lifting cylinder 63 of the drilling mechanism 6 drives the lifting plate 61 to descend. The electric drill 64 and the air drill 65 complete the drilling process on the sealing strip. The entire process achieves efficient and precise processing of the sealing strip through the coordinated operation of various components.

[0039] Reference Figures 1-7Both the air drill 65 and the electric drill 64 are clamped and fixed to the connecting plate 68 by the upper clamping plate 66 and the lower clamping plate 67. The inner side of the connecting plate 68 is slidably mounted on the slide rail distributed along the length direction of the lifting plate 61 by a slider, and the side of the connecting plate 68 is fixedly connected to the drill bit fixing block 69 by the support block 681. There are two sets of air drills 65 between a single set of upper clamping plates 66 and lower clamping plates 67, and one set of electric drills 64 between a single set of upper clamping plates 66 and lower clamping plates 67. Both air drills 65 and electric drills 64 are equipped with baffle separators 70 at their output ends. After the clamping and fixing of the automotive sealing strip 3 and the end cutting are completed, the drilling process begins. The air drills 65 and electric drills 64 are firmly clamped to the connecting plate 68 by the upper clamping plate 66 and the lower clamping plate 67, respectively. There are two sets of air drills 65 and one set of electric drills 64 between a single set of clamping plates, and baffle separators 70 are installed at their output ends. The slider on the inner side of the connecting plate 68 slides along the slide rail along the length of the lifting plate 61, and its side is connected to the drill bit fixing block 69 through the support block 681, allowing for flexible position adjustment. When the lifting cylinder 63 of the drilling mechanism 6 drives the lifting plate 61 to descend along the lifting guide rail 62, the air drill 65 and the electric drill 64 move with the connecting plate 68 to the position corresponding to the drilling position of the sealing strip on the material support plate 2. After precise positioning, the air drill 65 and the electric drill 64 start, and with the baffle separator 70 preventing debris from flying, they perform efficient drilling operations on the sealing strip. This installation and operation method ensures stable operation of various types of drill bits and achieves high-quality completion of the sealing strip drilling process.

[0040] Reference Figures 1-7The clamping plate 43 of the clamping mechanism 4 is also equipped with a guide mechanism 44, which is located on both sides of the drive cylinder 41. The guide mechanism 44 includes a guide block 441 fixed to the bottom of the mounting plate 11 and a moving block 442 fixedly connected to the clamping plate 43. A guide rod 443 fixedly installed on the moving block 442 passes through the guide block 441, and a return spring 444 is fitted on the guide rod 443 between the moving block 442 and the guide rod 443. The bottom of the moving block 442 moves on the slide rail on the frame 1 via a slider, wherein the slide rail and the guide rod 443 are perpendicular to the length direction of the mounting plate 11. When processing the automotive sealing strip 3, after the sealing strip is placed on the material support plate 2, the drive cylinder 41 of the clamping mechanism 4 is activated. The output end of the drive cylinder 41 pushes the locking plate 42 and the clamping plate 43 to move towards the sealing strip. At this time, the guide mechanism 44 on the clamping plates 43 on both sides of the drive cylinder 41 works in coordination. The moving block 442 moves with the clamping plate 43. The guide rod 443 fixed on the moving block 442 passes through the guide block 441. At the same time, the slider at the bottom of the moving block 442 slides along the slide rail on the frame 1 perpendicular to the length direction of the mounting plate 11, ensuring the smoothness and accuracy of the movement of the clamping plate 43. During the movement, the return spring 444 between the guide rod 443 and the moving block 442 is compressed. After the clamping plate 43 firmly clamps the sealing strip, the drive cylinder 41 maintains pressure. After the processing is completed, the drive cylinder 41 retracts. Under the elastic force of the return spring 444, the moving block 442 drives the clamping plate 43 to reset along the slide rail and the guide rod 443, releasing the sealing strip. The entire process ensures the stable operation of the clamping mechanism 4 through the guide mechanism 44, providing a reliable positioning basis for the precise cutting and drilling of the sealing strip.

[0041] Reference Figures 1-7 An electrical box 12 is installed at the bottom of the frame 1, and the electrical box 12 is connected to the display screen 13 on the side of the frame 1. Protective nets 14 are installed on the sides and back of the frame 1, and a lighting lamp 15 is installed on the top of the frame 1. The electrical box 12 at the bottom of the frame 1 serves as the control core, integrating and processing the power and signals of each mechanism. Through the signal connection with the display screen 13 on the side of the frame 1, it displays the equipment's operating parameters, working status, and other information in real time, facilitating monitoring and parameter adjustment by the operator. The protective nets 14 installed on the sides and back of the frame 1 effectively block flying debris generated during processing, ensuring the personal safety of the operator and preventing external debris from entering and affecting equipment operation. Before starting the equipment, the operator can preset processing parameters on the display screen 13. After receiving the command, the electrical box 12 controls the clamping mechanism 4 to clamp the sealing strip, and the end cutting mechanism 5 and the drilling mechanism 6 execute the processing tasks sequentially. Throughout the entire processing, the lighting lamp 15 on the top of the frame 1 continuously provides sufficient illumination to ensure that the operator can clearly observe the processing of the sealing strip and the operating details of the equipment, so as to promptly detect and handle abnormalities and ensure that the processing is carried out efficiently, safely and stably.

[0042] Working principle: First, the operator places the automotive sealing strip 3 to be processed on the support plate 2 on the mounting plate 11 of the frame 1. At this time, the clamping mechanism 4 starts to work. The drive cylinder 41 at the bottom of the mounting plate 11 is activated, and the locking plate 42 at the drive output end drives the clamping plate 43 to move, firmly clamping the sealing strip on the support plate 2. At the same time, the guide mechanism 44 on the clamping plate 43 plays its role. With the cooperation of the guide rod 443 and the return spring 444, the moving block 442 ensures that the clamping process is smooth, further stabilizing the position of the sealing strip and preventing it from shifting during processing.

[0043] After the sealing strip is fixed, the end cutting mechanism 5 and the drilling mechanism 6 begin to perform the processing task. For the end cutting mechanism 5, the cutting component slide plate 51 located at both ends of the material support plate 2 slides on the slide rail of the frame 1 via the bottom slider and moves to the appropriate position; the horizontal adjustment component 522 and the vertical adjustment component 523 in the angle adjustment component 52 adjust the angle of the ultrasonic cutting component 53 according to the processing requirements via the first scale 5222, the second scale 5232, the arc-shaped adjustment groove 54 and the rotating hole 55; after the adjustment is in place, the ultrasonic cutting component 53 is started, and its output end passes through the blade cavity 531 on both sides of the placement seat. Under the guidance of the guide groove 532 of the automotive sealing strip 3, it performs irregular cutting on both ends of the sealing strip. The waste generated by cutting falls into the receiving cavity 534 through the guide drop groove 533 at the bottom of the blade cavity 531.

[0044] Simultaneously or after the end cutting, the drilling mechanism 6 begins operation. The lifting cylinder 63 on the frame 1 drives the lifting plate 61 to rise and fall on the lifting guide rail 62, causing the electric drill 64 and air drill 65 mounted on the front of the lifting plate 61 to move to the position corresponding to the sealing strip on the material support plate 2 to be drilled. The electric drill 64 or air drill 65 is selected according to the drilling requirements. The air drill 65 and electric drill 64 are fixed on the connecting plate 68 by the upper clamping plate 66 and the lower clamping plate 67. With the cooperation of the connecting plate 68 and the sliding rail of the lifting plate 61, the drilling position is precisely aligned. Then the electric drill 64 or air drill 65 is started to complete the drilling operation on the sealing strip. After the drilling is completed, the lifting plate 61 is reset under the action of the lifting cylinder 63.

[0045] In addition, during the entire processing, the alcohol gas pipe assembly 5211 installed on the bracket 521 is connected to an external alcohol container, and the alcohol is delivered to the alcohol nozzle 5212 at the cutter chamber 531 of the car sealing strip 3 through the pipe, so as to lubricate the car sealing strip 3 entering the cutter chamber 531 and the cutting area, ensuring its processing quality and tool life.

[0046] After the cutting and drilling of a sealing strip is completed, the drive cylinder 41 of the clamping mechanism 4 retracts, releasing the clamping plate 43. The operator then removes the finished sealing strip, places a new sealing strip to be processed, and repeats the above operation process to achieve continuous automated processing of automotive sealing strips 3. The operator can monitor the equipment operating status and processing parameters transmitted by the electrical box 12 in real time through the display screen 13 on the side of the frame 1, and adjust and control the equipment as needed to ensure the smooth progress of the processing.

[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
