DETAILED DESCRIPTION

[0039] The following is a detailed description of the specific embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention and are not intended to limit the present invention.

[0040] In the present invention, unless otherwise stated, directional words such as "upper, lower, inside, outside" contained in a term merely represent the orientation of the term in normal usage, or are common names understood by those skilled in the art, and should not be regarded as limitations on the term.

[0041] Reference Figures 1-10As shown, a punching device for automobile interior panels comprises: an operating box 100, a clamping mechanism 300 arranged on the upper surface of the operating box 100 for clamping and limiting the interior panels, and a drill mechanism arranged above the clamping mechanism 300 for punching holes in the interior panels. A dust collection mechanism 400 is arranged inside the operating box 100 for collecting dust and debris generated on the operating box 100 during punching. The clamping mechanism 300 comprises at least two groups of clamping units that are spaced apart and relatively arranged on the upper surface of the operating box 100 and the spacing between the two groups is adjustable. Limit blocks 306 with adjustable spacing are also provided at both ends of each group of clamping units, and the adjusted limit blocks 306 can achieve position self-locking.

[0042] In the above scheme, the automobile interior panel to be drilled is placed on the upper surface of the operating box 100. The panel is secured by a clamping mechanism 300 and a stop block 306. Simultaneously, the drill mechanism within the operating box 100 is controlled to slide back and forth until the drill bit 104 is aligned with the desired location on the interior panel. Once the drill mechanism reaches the designated location, drilling begins on the interior panel, and the drill mechanism is driven to rotate and move left and right to complete the drilling process. During the drilling process, the material on the interior panel is drilled through, generating dust and debris. Simultaneously, the dust collection mechanism 400 within the operating box 100 is activated, sucking the dust and debris generated during the drilling process into the interior of the operating box 100, where it is filtered and collected to maintain a clean working environment.

[0043] Reference Figure 6-Figure 9 As shown, the clamping unit includes: a clamping block 304, a rack 305 and a limit block 306; the racks 305 are respectively slidably passed through the two side ends of the clamping block 304, and the interior of the clamping block 304 is horizontally rotatably provided with a gear 308 respectively engaged with the two racks 305 through a vertical rotating shaft 307, and the two racks 305 are located at the opposite ends of the outside of the clamping block 304 and the limit blocks 306 are respectively provided; the clamping block 304 is also provided with a locking member for locking at least one rack 305; the top of the rotating shaft 307 passes through the clamping block 304 and is provided with an operating handle 309.

[0044] In the above scheme, when the clamping blocks 304 begin to clamp the interior panel, as the clamping blocks 304 approach, the interior panel is clamped between them. At this time, if the width of the interior panel is greater than the initial spacing of the clamping blocks 304, the limit blocks 306 will come into play. The operator rotates the handle 309 to rotate the shaft 307, which drives the gear 308 to rotate. Since the gear 308 meshes with the rack 305, it drives the rack 305 to move. During this process, the limit blocks 306 adjust their position as the rack 305 moves until they are close to both ends of the interior panel or reach the appropriate limit position. After the limit blocks 306 secure the interior panel, the main unit of the punching device begins to operate, and the punching operation is carried out according to a preset program or manual operation. The coordinated use of the rack 305, gear 308, and limit blocks 306 can achieve precise limit of the width of the interior panel, ensuring that the interior panel remains in a stable position during the punching process and improving the punching accuracy.

[0045] Reference Figure 10 As shown, the self-locking part includes: a ratchet 310, a pawl 311 and a spring 313; wherein, the ratchet 310 is fixed on the back of one group of racks 305, and a pawl 311 is provided at the edge of the clamping block 304 for rotation. The pawl 311 is used in conjunction with the ratchet 310, and a pressing plate 312 is fixed on the side of the pawl 311 away from the ratchet 310, and a spring 313 is fixed on the back of the clamping block 304, and the top of the spring 313 is fixedly connected to the back of the pressing plate 312.

[0046] When it is necessary to punch and position the automobile interior panel, the pressing plate 312 is pressed downward, so that the pressing plate 312 squeezes the spring 313 and drives the pawl 311 to rotate, so that the pawl 311 moves away from the ratchet 310. At this time, the rack 305 can be driven to move by rotating the rotating shaft 307. When the rack 305 drives the limit block 306 to move to the specified position, the pressing plate 312 is released. Under the elastic force of the spring 313, the pawl 311 rotates and engages with the ratchet 310, thereby locking the rack 305. When the limit block 306 is supported from the inner wall of the interior panel, it is only necessary to rotate the rotating shaft 307 to drive the rack 305 to move. At this time, the pawl 311 is always coordinated with the ratchet 310, so that the rack 305 is locked when supporting.

[0047] Reference Figure 3-Figure 6 As shown, a third motor 301 is provided on the side of the operating box 100, the output shaft of which is arranged horizontally and the top end is fixedly connected to a screw 302 arranged in the operating box 100 through a shaft coupling, and the screw 302 is provided with two sections of threads with opposite screw directions, and the two sections of threads are respectively threaded with thread blocks 303, and a clamping block 304 is fixed on the thread block 303.

[0048] When in use, the third motor 301 is started, and the third motor 301 drives the screw 302 to rotate. Since the screw 302 is provided with two sections of threads with opposite directions, the two threaded blocks 303 will move relative to each other along the thread direction of the screw 302. As the threaded block 303 moves, the clamping block 304 fixed thereon gradually approaches the two ends or edges of the interior panel. The limiter in the clamping block 304 is fine-tuned according to the width of the interior panel to ensure that the interior panel is firmly clamped in the center position to prevent movement or offset during the punching process. After the clamping and fixing are completed, the interior panel is positioned and calibrated by the limiter to ensure the accuracy of the punching position.

[0049] Reference Figure 2-Figure 3 As shown, the dust suction mechanism 400 includes: a mounting plate 401, a fan 402 and a filter 403; wherein, the mounting plate 401 is fixedly arranged on the bottom surface of the operating box 100, and a mounting block 203 is fixedly arranged thereon, and the inner wall of the operating box 100 is located above the fan 402 and is slidingly provided with a filter 403, and the upper surface of the operating box 100 is located below the drill bit 104 and is provided with a discharge port 404 passing through the operating box 100, and the operating box 100 is also provided with an anti-blocking component 500 for driving the filter 403 to vibrate to prevent blockage.

[0050] Before or during the punching operation, the fan 402 is started. The fan 402 rotates to generate suction, and the dust and debris generated during the punching process are sucked into the inside of the operating box 100 through the discharge port 404. The sucked dust and debris are filtered by the filter 403 and blocked outside the filter 403, while the clean air enters the air outlet side of the fan 402 through the filter 403 and is finally discharged outside the operating box 100. As the punching operation proceeds, dust and debris will gradually accumulate on the filter 403. In order to prevent the filter 403 from being blocked and affecting the dust collection effect, the anti-blocking component 500 will knock on the filter 403.

[0051] Reference Figure 3-Figure 6 As shown, the anti-blocking component 500 includes: a second motor 501, a rotating rod 502, a cam 503 and a spring column 504; wherein, the second motor 501 is fixedly arranged on the side wall of the operating box 100, its output shaft is arranged horizontally and the top end is fixedly connected to the rotating rod 502 through a shaft coupling, and a plurality of cams 503 are fixedly sleeved at intervals on the rotating rod 502, and the side edges of the cams 503 are in contact with the surface of the filter 403, and a second limiting groove 505 for sliding the filter 403 is opened on the side of the operating box 100, and a spring column 504 is fixedly provided on the upper surface of the second limiting groove 505, and the top end of the spring column 504 is fixedly connected to the bottom surface of the filter 403.

[0052] When in use, the second motor 501 is started, and its output shaft drives the rotating rod 502 to rotate. As the rotating rod 502 rotates, the cam 503 also rotates. When the long side of the cam 503 contacts the surface of the filter 403, the filter 403 is pushed downward in the horizontal direction. When the long side of the cam 503 is away from the surface of the filter 403, the filter 403 is pushed upward in the horizontal direction under the action of the spring column 504. In this reciprocating manner, the cam 503 periodically contacts the filter 403 to cause it to vibrate, which helps to shake off dust and debris attached to the surface of the filter 403 to prevent excessive accumulation and blockage.

[0053] Reference Figure 1-Figure 5 As shown, the drill mechanism includes: a support member, a drill bit 104 that can slide left and right along the support member; wherein, the support member is provided with a first driving mechanism 200 for driving the drill bit 104 to slide left and right along the support member, and the operating box 100 is provided with a second driving mechanism for driving the support member to move back and forth on the operating box 100.

[0054] In the above scheme, the automobile interior panel to be punched is placed on the upper surface of the operation box 100, and the second driving mechanism in the operation box 100 is controlled to make the drill bit 104 slide back and forth along the upper surface of the operation box 100 until the drill bit 104 is aligned with the position where a hole is to be punched on the interior panel. After the drill bit 104 reaches the specified position, the first driving mechanism 200 is started. The first driving mechanism 200 works to drive the drill bit 104 to slide left and right along the support member, and starts the drilling operation on the interior panel. The drill bit 104 rotates under the drive of the motor and moves left and right along the support member to complete the drilling action.

[0055] Reference Figure 1-Figure 2 As shown, the support member includes: a mobile frame 101, an electric telescopic rod 102 and a sliding plate 103; wherein, the mobile frame 101 is vertically slidably arranged in a first limiting groove 205 on the upper surface of the operating box 100, and the top of the mobile frame 101 is fixedly provided with an electric telescopic rod 102, whose output shaft is vertically downwardly arranged and the top is fixedly connected to the sliding plate 103, and the side wall of the mobile frame 101 is provided with a sliding groove 105 for the sliding plate 103 to slide, and the first motor 201 is fixedly installed on the side of the sliding plate 103.

[0056] In the above embodiment, before the drilling device begins operation, the movable frame 101 is located in its initial position within the first limiting groove 205 on the upper surface of the operating box 100, the electric telescopic rod 102 is retracted, and the sliding plate 103 is located at the top of the slide groove 105 in the side wall of the movable frame 101 or at a predetermined starting position. The first motor 201 is fixedly mounted on the side of the sliding plate 103 but has not yet been activated. Based on the required height of the interior panel or the required drilling position, the electric telescopic rod 102 is activated, and its output shaft extends vertically downward, pushing the sliding plate 103 to slide downward along the slide groove 105 in the side wall of the movable frame 101. During this process, the first motor 201 and the drill bit 104 it drives also descend until the predetermined drilling height is reached.

[0057] Reference Figure 1-Figure 5 As shown, the first driving mechanism 200 includes: a first motor 201, a bidirectional screw rod 202, and a mounting block 203; wherein, the first motor 201 is fixedly arranged on the side of the sliding plate 103, its output end is horizontally arranged and the top end is fixedly connected to the bidirectional screw rod 202 through a shaft coupling, the bidirectional screw rod 202 is threaded with a mounting block 203, and the drill bit 104 is fixedly arranged on the bottom surface of the mounting block 203.

[0058] During use, the first motor 201 is started, and its output end begins to rotate, driving the bidirectional screw 202 to rotate synchronously through the coupling. As the bidirectional screw 202 rotates, the mounting block 203, which is threadedly engaged with it, begins to move left and right along the screw. Because the screw is bidirectional, the mounting block 203 can be controlled to move left or right depending on the direction of motor rotation. The movement of the mounting block 203 drives the drill bit 104 to move synchronously, allowing the drill bit to slide left and right along the support mechanism, thereby drilling a hole in the interior panel. The drill bit remains rotating during movement to ensure smooth drilling. When the drill bit 104 completes the preset drilling path, the first motor 201 is turned off, stopping the movement and rotation of the drill bit, completing the drilling operation.

[0059] Reference Figure 3 As shown, the second driving mechanism includes: a linear slide 204, which is fixed on the operating box 100, and the moving seat of the linear slide 204 is fixedly connected to the bottom surface of the moving frame 101, and the operating box 100 is provided with a first limiting groove 205 for the moving frame 101 to slide.

[0060] In the above solution, because the support mechanism is fixedly connected to the movable base of the linear slide 204, the support mechanism simultaneously slides back and forth along the upper surface of the operating box 100 as the movable base moves. During this sliding process, the support mechanism is guided and restrained by the first limiting groove 205, ensuring the accuracy and stability of its sliding trajectory. When the support mechanism slides to the preset position, the drill bit 104 also reaches the precise location on the interior panel where the hole is to be drilled. At this point, the first drive mechanism 200 can be activated, causing the drill bit to slide left and right along the support mechanism to perform the drilling operation.

[0061] In summary, the present invention provides a punching device for automobile interior panels. When in use, the automobile interior panel to be punched is placed on the upper surface of the operating box 100. When the clamping block 304 begins to clamp the interior panel, as the clamping block 304 approaches, the interior panel is clamped between the two. According to the width of the interior panel, the pressing plate 312 is pressed downward, so that the pressing plate 312 squeezes the spring 313 and drives the pawl 311 to rotate, so that the pawl 311 is away from the ratchet 310. The operator drives the rotating shaft 310 by rotating the operating handle 309. 07 turns to drive gear 308 to rotate. Since gear 308 is engaged with rack 305, rack 305 is driven to move. During this process, limit block 306 adjusts its position as rack 305 moves until it is close to both ends of the interior panel or reaches a suitable limit position. The pressing plate 312 is released, and under the elastic force of spring 313, the pawl 311 rotates and engages with the ratchet 310, thereby locking rack 305. The main part of the punching device starts to work and performs punching operations according to the preset program or manual operation.
