[0006] To achieve the above objectives, this utility model provides the following technical solution: a novel linkage clamping mechanism, comprising a processing platform and a drive scraping mechanism. The processing platform is internally provided with the drive scraping mechanism, which includes a nut seat slidably connected to the inner surface of the processing platform. A scraper is fixedly connected to the outer surface of the nut seat.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model, through the setting of the drive scraping mechanism, has the dual functions of cleaning and auxiliary clamping, avoiding the accumulation of impurities that affect the subsequent processing accuracy, maintaining the cleanliness of the processing platform, eliminating the need for additional cleaning equipment, and synchronizing the scraping action with the processing flow, reducing downtime for cleaning.

[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] like Figures 1-2As shown, a novel linkage clamping mechanism includes a processing platform 1 and a drive scraping mechanism 2. The drive scraping mechanism 2 is installed inside the processing platform 1, and includes a nut seat 201 slidably connected to the inner surface of the processing platform 1. A scraper 202 is fixedly connected to the outer surface of the nut seat 201, a double-segment lead screw 203 is threadedly connected to the inner surface of the nut seat 201, and a guide rod 204 is slidably connected to the inner surface of the nut seat 201. A discharge port 205 is opened at the bottom of the inner surface of the processing platform 1, and the... An extended protective mechanism 3 is fixedly connected to one side of the processing platform 1. A double-segment screw 203 and a guide rod 204 pass through the processing platform 1 in parallel. The nut seat 201 is threadedly engaged with the double-segment screw 203 and slidably connected to the guide rod 204. When the double-segment screw 203 is rotated, the nut seat 201 drives the scraper 202 outside the nut seat 201 to move back and forth along the guide rod 204. The scraper 202 is made of wear-resistant steel with high hardness and can scrape off the inner wall debris, which is discharged through the discharge port 205. The double-segment screw 203 can also be adapted to clamp workpieces of different lengths.

[0023] like Figures 3-4 As shown, the extended protective mechanism 3 includes an extended plate 301 disposed on one side of the processing platform 1, and a rotating shaft 302 is fixedly connected to one side of the extended plate 301. A reinforcing protective plate 303 is fixedly connected to one side of the rotating shaft 302, and a rubber protective pad 304 is fixedly connected to one side of the reinforcing protective plate 303. The extended plate 301 adopts a telescopic nested structure and is fixed by bolts. The extension length can be freely adjusted according to the length of the workpiece to adapt to different specifications. The reinforcing protective plate 303 is made of high-strength metal and has strong impact resistance. It can resist external impacts and effectively block debris from flying. The rubber protective pad 304 is attached to the inner side of the reinforcing protective plate 303. It is soft in texture, buffers the collision of the workpiece, and prevents surface wear.

[0024] Furthermore, a buffer damper 4 is fixedly connected to the top of the extension plate 301, and a plate 5 is fixedly connected to the top of the buffer damper 4. A dust collection box 6 is provided at the bottom of the discharge port 205, and a triangular three-dimensional pressure block 7 is fixedly connected to the top of the nut seat 201. The plate 5 and the processing platform 1 are on the same horizontal line, which is convenient for placing the workpiece. Multiple sets of buffer dampers 4 make the workpiece bear force evenly during processing, improving the accuracy of processing. The dust collection box 6 collects debris and dust for unified treatment.

[0025] Furthermore, an elastic rod 8 is fixedly connected to one side of the triangular solid pressure block 7, and a rubber pressure plate 9 is fixedly connected to one end of the elastic rod 8. A conveying pipe 10 is fixedly connected to the top of the triangular solid pressure block 7, and a storage box 11 is fixedly connected to one end of the conveying pipe 10. The triangular solid pressure block 7 forms a stable clamping surface with the rubber pressure plate 9 based on the three-point support principle, increasing the contact area. The elastic rod 8 has a built-in spring structure, which absorbs pressure under pressure deformation and avoids rigid extrusion. The rubber pressure plate 9 is made of flexible material, which conforms to the contour of the workpiece to reduce friction. The conveying pipe 10 is driven by a pressure pump inside the storage box 11. After passing through the triangular solid pressure block 7, the lubricant is evenly covered through the small spray holes at the bottom of the conveying pipe 10 to prevent jamming.

[0026] Furthermore, a bracket 12 is fixedly connected to the bottom of the processing platform 1, and an anti-slip pad 13 is fixedly connected to the bottom of the bracket 12. The bracket 12 provides stable support for the clamping mechanism, and the bottom anti-slip pad 13 increases friction and effectively prevents displacement.

[0027] Working principle: When using this new type of linkage clamping mechanism, firstly, according to the length of the workpiece, adjust the extension plate 301 of the extension protection mechanism 3 to extend and retract to the appropriate length. At the same time, the reinforcing protection plate 303 is unfolded through the rotating shaft 302 to form an outer barrier. The workpiece is placed on the flat plate 5 of the processing platform 1, and the rubber protective pad 304 fits against the edge of the workpiece. Then, rotate the double-segment screw 203 to drive the triangular three-dimensional pressure block 7 at the top of the nut seat 201 of the drive scraping mechanism 2 to move, so that the rubber pressure plate 9 evenly fits against the surface of the workpiece, achieving stable clamping. The elastic rod 8 is compressed and generates elastic deformation. The pressure of the buffer rubber plate 9 on the workpiece is changed to prevent overpressure damage. At the same time, the scraper 202 on the outer surface of the nut seat 201 scrapes away the debris from the inner wall of the processing platform 1. The debris falls into the dust collection box 6 through the discharge port 205. The lubricating fluid in the storage box 11 is transported to the surface of the double-segment lead screw 203 through the conveying pipe 10 to ensure smooth transmission. Finally, during the processing, the reinforced protective plate 303 blocks splashing debris, the buffer damper 4 reduces the vibration of the mechanism, and the anti-slip pad 13 at the bottom of the bracket 12 increases the friction with the contact surface to prevent the mechanism from shifting. This is the working principle of the new linkage clamping mechanism.
