Description

Technical Field

[0001] This invention relates to the field of burr-free cutting devices, and more particularly to a burr-free cutting device for processing automotive slide rails. Background Technology

[0002] Automotive slide rails are key structural components in automotive seat adjustment systems. They are typically made from high-strength cold-rolled steel sheets that are roll-formed and then cut to a fixed length. The length accuracy and end-face quality of the slide rails directly affect the installation reliability and smoothness of the seat adjustment mechanism. In the mass production of slide rails, the cutting process is a crucial step in determining the quality of the final product.

[0003] During cutting, due to the relatively weak rigidity of the workpiece, the impact force generated by the contact between the cutting tool and the workpiece can easily induce workpiece vibration. Vibration will cause the cutting trajectory to deviate, resulting in wavy patterns or local tearing on the end face, further aggravating the formation of burrs. The clamps of existing cutting equipment usually only press from the upper and lower directions of the slide rail, lacking multi-point support for the sides and inner cavity, and cannot effectively suppress the instantaneous vibration of the cutting area. Summary of the Invention

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments.

[0020] The beneficial effects of this invention are:

[0021] 1. By using a load-bearing platform, bracket, connecting plate, protective frame, first moving groove and automobile slide rail body, the automobile slide rail body is placed in the clamping and feeding structure, so that the product can be quickly loaded and unloaded. At the same time, the first moving groove allows the internal structure of the clamping and feeding structure to move within it, thereby improving the clamping effect of the equipment to a certain extent.

[0022] 2. Utilizing a mounting plate, a first electric push rod, a rubber clamping plate, a locking frame, an n-shaped frame, a second rubber pad, an insertion slot, and an insertion rod, the first electric push rod drives the rubber clamping plate to move towards one side of the car slide rail body during processing. This prevents vibration on both sides of the car slide rail body during processing, thus reducing the amount of burrs during processing. Furthermore, the locking frame accommodates the n-shaped frame, and the second rubber pad on the lower surface of the n-shaped frame presses against the upper surface of the car slide rail body. Finally, the insertion rod simultaneously limits the position of the n-shaped frame, thereby improving the clamping and installation effect of the equipment to a certain extent.

[0023] 3. Utilizing a movable frame, a second electric push rod, a first rubber pad, a pressure plate, an adjusting motor, an I-shaped rod, a drive shaft, a transmission plate, a first lead screw, a pressure spring, a storage frame, a waste trough, a second movable trough, a micro motor, and a first guide rod, the output shaft of the adjusting motor quickly drives the first lead screw to rotate, which in turn drives the transmission plate to move within the first movable trough. This allows the movable frame to be quickly driven by the transmission plate, moving the pressure plate to the appropriate position, thereby enabling the first rubber pad to quickly press and position the automotive slide rail body.

[0024] 4. Using a suction pipe, support plate, discharge pipe, waste bin, cutting blade, collection frame, limit triangular rod, and first cleaning brush, the output shaft of the rotary motor drives the cutting blade to rotate. The cutting blade can cut the car slide rail body under rapid rotation. When the cutting blade is cutting, its outer surface comes into contact with the first and second cleaning brushes, so that the waste on its surface is cleaned during the rotation of the cutting blade. Furthermore, the cutting edge of the cutting blade is continuously ground by the grinding frame to maintain the cutting effect of the product during the processing and prevent the blunt edge from appearing after long-term operation of the equipment.

[0025] 5. Utilizing a lifting plate, extrusion plate, drive motor, limit guide rod, second guide rod, second lead screw, auxiliary frame, and fourth electric push rod, the output shaft of the drive motor rapidly drives the second lead screw to rotate, which in turn drives the lifting plate. The lifting plate moves up and down along the limit guide rod and second guide rod, thus rapidly raising and lowering the cutting blade during its movement, improving the continuous cutting effect of the equipment. Further, during cutting, a third electric push rod drives the auxiliary frame to extend into the automotive slide rail body, and the fourth electric push rod then presses the extrusion plate against the inner surface of the automotive slide rail body, clamping and squeezing the waste end to prevent strong vibrations during cutting and reduce burr formation to some extent. When the equipment is working, a waste trough is used to discharge the waste generated during cutting to prevent its accumulation. Simultaneously, the waste from the cut slide rails can also be discharged through the waste trough, allowing the equipment to perform continuous cutting to a certain extent.

[0038] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0039] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0040] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it an embodiment that is mutually exclusive, either alone or selectively, with other embodiments.

[0041] Secondly, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.

[0042] Example 1:

[0043] Reference Figure 1 - Figure 10 According to one embodiment of the present invention, a burr-free cutting device for processing automotive slide rails is provided, including a main structure 100, a clamping and feeding structure 200 and a cutting and collecting structure 300.

[0044] The main structure 100 includes a load-bearing platform 101 and a bracket 102 fixedly connected to the lower surface of the load-bearing platform 101. A connecting plate 103 is fixedly connected to one side of the load-bearing platform 101. A protective frame 104 is fixedly connected to the upper surface of the connecting plate 103. A first moving groove 105 is opened on the upper surface of the load-bearing platform 101.

[0045] Furthermore, the clamping and feeding structure 200 includes a mounting plate 201 fixedly connected to the upper surface of the support platform 101 and a moving frame 209 slidably connected to the inner surface of the first moving groove 105. A second moving groove 221 is opened on the inner surface of the support platform 101, and a transmission plate 216 is slidably connected to the inner surface of the second moving groove 221.

[0046] Finally, the cutting and collecting structure 300 includes a drive motor 303 fixedly connected to the upper surface of the protective frame 104 and a limiting guide rod 314 fixedly connected to the inner surface of the protective frame 104. A third electric push rod 315 is fixedly connected to the inner surface of the protective frame 104, and an auxiliary frame 327 is fixedly connected to one end of the third electric push rod 315.

[0047] Furthermore, a first electric push rod 202 is fixedly connected to one side of the mounting plate 201, and a rubber clamping plate 203 is fixedly connected to the side of the first electric push rod 202 away from the mounting plate 201. There are several mounting plates 201, all symmetrically distributed at equal intervals on the upper surface of the support platform 101. A storage frame 219 is fixedly connected to the upper surface of the support platform 101, and a pressure spring 218 is fixedly connected to the upper surface of the support platform 101. The pressure spring 218 is located on the inner surface of the storage frame 219, and an I-shaped rod 214 is fixedly connected to the upper surface of the pressure spring 218. Thus, through the several symmetrically distributed mounting plates 201 and the first electric push rod 202 on them, the air... Clamping forces are applied to both sides of the car slide rail body 106. The rubber clamping plate 203 flexibly contacts the side of the slide rail, providing sufficient lateral support to suppress lateral vibration during cutting and avoiding scratching the workpiece surface. The pressure spring 218 in the storage frame 219 pushes the I-shaped rod 214 upward, so that the upper surface of the I-shaped rod 214 always keeps in contact with the lower surface of the car slide rail body 106, forming an auxiliary support from bottom to top. Together with the upper clamping mechanism, it forms a vertical clamping, reducing the vertical jump during cutting. This multi-point lateral and bottom support structure effectively solves the problem that traditional clamps only clamp from the top and bottom and lack lateral and internal cavity support, significantly suppressing instantaneous vibration in the cutting area.

[0048] Furthermore, the upper surface of the I-shaped rod 214 contacts the automobile slide rail body 106, and a locking frame 204 is fixedly connected to the upper surface of the support platform 101. An insertion slot 207 is provided on one side of the locking frame 204. There are two sets of locking frames 204, and both sets are symmetrical about the center of the support platform 101. An n-shaped frame 205 is slidably connected to the inner surface of the locking frame 204. Insertion slots 207, identical to those of the locking frame 204, are provided on both sides of the n-shaped frame 205. A locking rod 208 is inserted into the insertion slot 207. The two sets of symmetrical locking frames 204 provide vertical support for the n-shaped frame 205. The sliding guide allows the lower surface of the n-shaped frame 205 to contact and apply pressure to the upper surface of the automotive slide rail body 106. When the n-shaped frame 205 slides to the predetermined position, the insertion rod 208 simultaneously passes through the insertion slot 207 on both the locking frame 204 and the n-shaped frame 205, achieving relative locking between the two and keeping the n-shaped frame 205 in a pressed state. This structure can quickly adjust the pressing position according to the height of different slide rails and achieves mechanical self-locking through the insertion rod 208, preventing the n-shaped frame 205 from loosening due to vibration during the cutting process, ensuring a constant pressing force on the upper surface, and further suppressing the vibration of the workpiece in the vertical direction.

[0049] Furthermore, the outer diameter of the insertion rod 208 is compatible with the inner diameter of the insertion slot 207. A second electric push rod 210 is fixedly connected to the inner surface of the moving frame 209. A pressure plate 212 is fixedly connected to the lower surface of the second electric push rod 210. A first rubber pad 211 is fixedly connected to the lower surface of the pressure plate 212. A second rubber pad 206 is fixedly connected to the lower surface of the n-shaped frame 205. One end of the transmission plate 216 is fixedly connected to one side of the moving frame 209. There are two sets of moving frames 209, and both sets of moving frames 209 are symmetrical about the center of the transmission plate 216. An adjusting motor 213 is fixedly connected to one side of the support platform 101. A first lead screw 217 is fixedly connected to one end of the output shaft of the adjusting motor 213. The insertion rod 208 and the insertion slot 207 are connected through... The precise fit eliminates gaps after locking, ensuring that the n-shaped frame 205 does not shift during cutting; the second electric push rod 210 inside the moving frame 209 drives the pressure plate 212 to descend, and the first rubber pad 211 contacts the upper surface of the car slide rail body 106 and applies auxiliary clamping force, forming multiple vertical pressure points distributed front and back with the second rubber pad 206 of the n-shaped frame 205, so that the slide rail is evenly stressed along its entire length; the two sets of moving frames 209 are symmetrical about the center of the transmission plate 216, and the adjusting motor 213 drives the first lead screw 217 to rotate, driving the transmission plate 216 and the two sets of moving frames 209 to move synchronously, thereby flexibly adjusting the position of the auxiliary clamping point according to the cutting position, ensuring that there is always sufficient clamping force near the cutting area, and reducing the vibration of the cantilever section.

[0050] Furthermore, a first guide rod 223 is fixedly connected inside the load-bearing platform 101. The outer surface of the first guide rod 223 is slidably connected to the transmission plate 216. The outer surface of the first lead screw 217 is threadedly connected to the transmission plate 216. The outer surface of the transmission plate 216 is slidably connected to the inner surface of the second moving groove 221. A waste trough 220 is provided at the end of the load-bearing platform 101 away from the adjusting motor 213. A rotating groove is provided on the upper surface of the I-shaped rod 214, and a micro motor 222 is fixedly connected inside the rotating groove. A drive shaft 215 is fixedly connected to one end of the output shaft of the micro motor 222. The upper surface of the drive shaft 215 is in contact with the lower surface of the n-shaped frame 205. The first guide rod 223 provides linear guidance for the movement of the transmission plate 216, and the first lead screw 217 converts the rotational motion of the adjusting motor 213 into linear motion. For precise linear displacement of the transmission plate 216, the transmission plate 216 slides smoothly along the second moving groove 221, thereby driving the moving frame 209 to accurately reach the preset position; the waste groove 220 is used to discharge the waste and chips generated during cutting, preventing accumulation from affecting processing; the micro motor 222 fixed in the rotating groove on the upper surface of the I-shaped rod 214 drives the drive shaft 215 to rotate, and the upper surface of the drive shaft 215 contacts the lower surface of the car slide rail body 106. When the workpiece is loaded, the rotation of the micro motor 222 assists the car slide rail body 106 to move towards the protective frame 104, reducing the labor intensity of manual operation, while ensuring that the lower surface of the n-shaped frame 205 is in uniform contact with the upper surface of the car slide rail body 106, improving clamping accuracy and consistency, and providing a stable and reliable clamping foundation for suppressing cutting vibration.

[0051] Working principle:

[0052] By utilizing the load-bearing platform 101, bracket 102, connecting plate 103, protective frame 104, first moving groove 105, and automobile slide rail body 106, the automobile slide rail body 106 is placed inside the clamping and feeding structure 200, thereby enabling products to be loaded and unloaded quickly. At the same time, the first moving groove 105 allows the internal structure of the clamping and feeding structure 200 to move within it, thereby improving the clamping effect of the equipment to a certain extent.

[0053] By utilizing the mounting plate 201, the first electric push rod 202, the rubber clamping plate 203, the locking frame 204, the n-shaped frame 205, the second rubber pad 206, the insertion groove 207, and the insertion rod 208, the car slide rail body 106 is processed. Furthermore, the first electric push rod 202 drives the rubber clamping plate 203 to move towards one side of the car slide rail body 106, preventing vibration on both sides of the car slide rail body 106 during processing and thus reducing burrs. The locking frame 204 further accommodates the n-shaped frame 205, and the second rubber pad 206 on the lower surface of the n-shaped frame 205 presses against the upper surface of the car slide rail body 106. Finally, the insertion rod 208 simultaneously limits the n-shaped frame 205, thereby improving the clamping and installation effect of the equipment to a certain extent.

[0054] Using a movable frame 209, a second electric push rod 210, a first rubber pad 211, a pressure plate 212, an adjusting motor 213, an I-shaped rod 214, a drive shaft 215, a transmission plate 216, a first lead screw 217, a pressure spring 218, a storage frame 219, a waste trough 220, a second movable groove 221, a micro motor 222, and a first guide rod 223, the output shaft of the adjusting motor 213 quickly drives the first lead screw 217 to rotate, which in turn drives the transmission plate 216 to move within the first movable groove 105. This causes the movable frame 209 to be quickly driven by the transmission plate 216, moving the pressure plate 212 to the appropriate position, thereby allowing the first rubber pad 211 to quickly press and position the car slide rail body 106.

[0055] The rotary motor 316 output shaft drives the cutting blade 311 to rotate using a suction pipe 304, support plate 305, discharge pipe 306, waste bin 309, cutting blade 311, collection frame 320, limiting triangular rod 313, and first cleaning brush 324. The cutting blade 311 can cut the car slide rail body 106 by rotating rapidly. When the cutting blade 311 is cutting, its outer surface comes into contact with the first cleaning brush 324 and the second cleaning brush 325, so that the waste on its surface is cleaned during the rotation of the cutting blade 311. Furthermore, the grinding frame 326 continuously grinds the cutting edge of the cutting blade 311 to maintain the cutting effect of the product during the processing and prevent the equipment from becoming dull after long-term operation.

[0056] The system utilizes a lifting plate 301, an extrusion plate 312, a drive motor 303, a limiting guide rod 314, a second guide rod 318, a second lead screw 319, an auxiliary frame 327, and a fourth electric push rod 328. The output shaft of the drive motor 303 rapidly drives the second lead screw 319 to rotate, which in turn drives the lifting plate 301. The lifting plate 301 rises and falls along the limiting guide rod 314 and the second guide rod 318, thereby rapidly raising and lowering the cutting blade 311 during its movement. This improves the continuous cutting effect of the equipment. Furthermore, during cutting, the system utilizes… The third electric push rod 315 drives the auxiliary frame 327 to extend into the car slide rail body 106, and then the fourth electric push rod 328 presses the extrusion plate 312 against the inner surface of the car slide rail body 106, so as to squeeze and clamp the waste end, thereby avoiding strong vibration of the product during cutting, and thus reducing the degree of burr generation to a certain extent. When the equipment is working, the waste material generated by cutting is discharged through the waste material trough 220 to prevent its accumulation. At the same time, the cut slide rail waste can also be discharged through the waste material trough 220, thereby enabling the equipment to continuously perform cutting processing to a certain extent.

[0058] Reference Figure 2 - Figure 10 The difference from Embodiment 1 is that: a second guide rod 318 is fixedly connected inside the protective frame 104; a second lead screw 319 is fixedly connected to one end of the output shaft of the drive motor 303; a lifting plate 301 is threadedly connected to the outer surface of the second lead screw 319; the outer surface of the second guide rod 318 is slidably connected inside the lifting plate 301; one side of the lifting plate 301 is slidably connected to one side of the limiting guide rod 314; and a connecting rod 307 is fixedly connected to the side of the lifting plate 301 away from the limiting guide rod 314. The second lead screw 319 is rotated by the drive motor 303, and the second lead screw 319 drives the lifting plate 301 via the thread. 1. The lifting plate 301 moves smoothly up and down along the second guide rod 318, which provides vertical guidance for the lifting plate 301 to prevent it from deflecting or shaking during the lifting process. One side of the lifting plate 301 slides with the limiting guide rod 314 to form a double guide structure, which further enhances the straightness and stability of the lifting movement. The connecting rod 307 is fixed on the side of the lifting plate 301 away from the limiting guide rod 314, and moves up and down synchronously with the lifting plate 301. It transmits the lifting power to the cutting blade mounting assembly below to ensure that the cutting blade can cut into the workpiece smoothly and accurately, and avoid wavy lines or burrs on the cutting surface caused by unstable feed.

[0059] Furthermore, a connecting block 302 is fixedly connected to the lower surface of the connecting rod 307, and symmetrically distributed fixing plates 310 are fixedly connected to the lower surface of the connecting block 302. Support plates 305 are fixedly connected to both sides of one set of fixing plates 310. A fixing block 323 is fixedly connected to one side of the fixing plate 310, and a collection frame 320 is fixedly connected to one side of the fixing block 323. A waste bin 309 is slidably connected inside the protective frame 104. A sliding groove 322 is provided on the upper surface of the waste bin 309, and a discharge pipe 306 is slidably connected inside the sliding groove 322. The fixing plate 310 is rigidly connected to the upper lifting structure via the connecting block 302. The connection allows the fixed plate 310 to rise and fall synchronously with the lifting plate 301; the symmetrically distributed fixed plates 310 form the mounting bracket for the cutting blade 311, and the support plate 305 provides lateral support to the fixed plate 310, enhancing the structural rigidity; the fixed block 323 fixes the collection frame 320 to one side of the fixed plate 310, and the collection frame 320 is used to collect the chips cleaned up during the cutting process; the waste bin 309 is slidably connected to the protective frame 104, and the sliding groove 322 on its upper surface is slidably engaged with the discharge pipe 306, so that the discharge pipe 306 can be disconnected when the position of the waste bin 309 is adjusted, which facilitates the collection and cleaning of waste chips.

[0060] Furthermore, a suction pipe 304 is fixedly connected to one end of the discharge pipe 306. The end of the suction pipe 304 away from the discharge pipe 306 is fixedly connected to one side of the collection frame 320. One side of the support plate 305 is fixedly connected to the outer surface of the suction pipe 304. A filter plate 308 is fixedly connected to one side of the waste bin 309. A symmetrically distributed fan 321 is fixedly connected to one side of the filter plate 308. The suction pipe 304 introduces the chip-laden air in the collection frame 320 into the discharge pipe 306, and then into the waste bin 309. The support plate 305 provides auxiliary fixation for the suction pipe 304 to prevent vibration from causing the pipe to loosen. After the fan 321 is started, a negative pressure is generated in the waste bin 309. The filter plate 308 intercepts the chips and allows the air to be discharged, achieving timely cleaning of the chips and preventing the chips from accumulating in the cutting area and being carried away by the blade, causing secondary burrs. The symmetrically distributed fan 321 ensures uniform suction force and improves dust collection efficiency.

[0061] Furthermore, a cutting blade 311 is rotatably connected to one side of the fixed plate 310, a connecting frame 317 is fixedly connected to the lower surface of the lifting plate 301, a rotary motor 316 is fixedly connected to the lower surface of the connecting frame 317, one end of the output shaft of the rotary motor 316 is fixedly connected inside the cutting blade 311, a fourth electric push rod 328 is fixedly connected to one side of the auxiliary frame 327, and a pressing plate 312 is fixedly connected to one end of the fourth electric push rod 328. The rotary motor 316, fixed to the lower surface of the lifting plate 301 via the connecting frame 317, drives the cutting blade 311 to rotate at high speed via its output shaft. The lifting plate 301... 1. When descending, the cutting blade 311 contacts the car slide rail body 106 to cut; the auxiliary frame 327 extends into the car slide rail body 106 under the drive of the third electric push rod 315, and the fourth electric push rod 328 pushes the extrusion plate 312 to stick tightly to the inner wall of the slide rail, forming an inner cavity support for the waste end near the cutting area. Together with the external rubber clamping plate 203, the second rubber pad 206 and the first rubber pad 211, it forms a multi-point clamping system, which effectively suppresses the lateral and vertical vibration of the slide rail during cutting, prevents the cutting trajectory deviation and wavy texture caused by vibration, and thus reduces the generation of burrs to a certain extent.

[0062] Furthermore, a limiting triangular rod 313 is fixedly connected inside the collection frame 320. A first cleaning brush 324 is fixedly connected to one side of the collection frame 320, and a second cleaning brush 325 is fixedly connected to one side of the fixing plate 310. A grinding frame 326 is fixedly connected to the side of the two fixing plates 310 that are close to each other. The inner surface of the grinding frame 326 is in contact with the outer surface of the cutting blade 311. The limiting triangular rod 313 is fixed inside the collection frame 320, and its inclined surface guides the sucked-up chips to slide smoothly into the inlet of the discharge pipe 306 to prevent blockage. The first cleaning brush 324 and the second cleaning brush 325 are located on both sides of the cutting blade 311, respectively. During the rotation of the blade, they continuously contact its surface, brushing off the adhering chips, keeping the blade clean, and avoiding... To prevent the cutting edge from dulling due to chip buildup, the grinding frame 326 is fixed between two sets of fixing plates 310. Its inner surface maintains slight contact with the outer surface of the cutting blade 311, and it grinds the blade online while the blade rotates, maintaining a sharp cutting edge and reducing cutting resistance. This reduces burrs and tears caused by tool dulling, achieving burr-free cutting.

[0063] Working principle: First, the main structure 100 of the equipment provides a stable installation base for each functional component. The support platform 101 is supported by the bracket 102. The upper surface of the platform is provided with a first moving groove 105 to guide the moving frame 209 in the clamping and feeding structure 200. The connecting plate 103 is fixed to one side of the support platform 101. The protective frame 104 on it provides installation space for the cutting and collecting structure 300. The car slide rail body 106 is placed on the upper surface of the I-shaped rod 214 of the clamping and feeding structure 200. The I-shaped rod 214 is lifted upward under the action of the pressure spring 218 in the storage frame 219, so that the bottom surface of the slide rail obtains uniform elastic support and avoids sagging deformation due to its own weight.

[0064] Secondly, lateral clamping is achieved by several symmetrically distributed mounting plates 201 at equal intervals. The first electric push rod 202 on each mounting plate 201 drives the rubber clamping plate 203 to simultaneously advance inward from both sides of the slide rail, applying a flexible but sufficient clamping force to the sides of the slide rail, effectively suppressing any lateral swaying that may occur during cutting. Vertical clamping is divided into main clamping and auxiliary clamping. Main clamping is achieved by the n-shaped frame 205: the operator slides the n-shaped frame 205 downward along the engaging frame 204, causing the second rubber pad 206 on its lower surface to contact the upper surface of the slide rail and apply initial clamping force; then, the insertion rod 208 simultaneously passes through the insertion slots 207 on both the engaging frame 204 and the n-shaped frame 205 to achieve... Mechanical self-locking ensures constant clamping force. Auxiliary clamping is completed by the second electric push rod 210 inside the moving frame 209: the second electric push rod 210 drives the pressure plate 212 to descend, the first rubber pad 211 contacts the upper surface of the slide rail, forming multiple vertical pressure points distributed front and back. The two sets of moving frames 209 are symmetrical about the center of the transmission plate 216. By adjusting the motor 213 to drive the first lead screw 217 to rotate, the transmission plate 216 and the moving frame 209 move synchronously along the first moving groove 105 and the second moving groove 221. Thus, the position of the auxiliary clamping point can be flexibly adjusted according to the position of the cutting blade 311 to ensure that there is always sufficient clamping force near the cutting area and reduce the vibration of the cantilever section.

[0065] Furthermore, the bottom auxiliary support is provided by the I-shaped rod 214, and the pressure spring 218 below it continuously pushes upward, so that the bottom surface of the slide rail always keeps in close contact with the upper surface of the I-shaped rod 214, which together with the clamping mechanism above forms a stable vertical constraint. For the waste end near the cutting area, the device is also equipped with an internal cavity support structure: the third electric push rod 315 drives the auxiliary frame 327 to extend into the interior of the car slide rail body 106, and the fourth electric push rod 328 pushes the extrusion plate 312 to stick tightly to the inner wall of the slide rail, forming an internal support for the waste end that is about to be cut off. Together with the external clamping point, it forms an all-round rigid constraint system, which fundamentally suppresses the impact vibration at the moment of cutting and prevents the cutting trajectory deviation and wavy texture caused by vibration.

[0066] Secondly, after the workpiece is clamped, the cutting and collecting structure 300 is activated, and the drive motor 303 drives the second lead screw 319 to rotate. The second lead screw 319 drives the lifting plate 301 to descend smoothly along the second guide rod 318 and the limiting guide rod 314 through the thread. The lower surface of the lifting plate 301 is fixed with a rotary motor 316 through the connecting frame 317. The output shaft of the rotary motor 316 drives the cutting blade 311 to rotate at high speed. When the lifting plate 301 descends to the predetermined position, the cutting blade 311 contacts the slide rail and begins to cut. Since the workpiece has been firmly clamped at multiple points, the impact force generated when the blade cuts is evenly distributed, and the slide rail will not vibrate significantly, thus ensuring the flatness of the cut end face.

[0067] If the metal chips generated during the cutting process are not removed in time, they will adhere to the blade or workpiece surface, aggravating secondary burrs. To address this, the device is equipped with a negative pressure suction system: the symmetrically distributed fans 321 on one side of the waste bin 309 are activated, generating negative pressure in the waste bin 309. The chip-containing air in the collection frame 320 is drawn in through the discharge pipe 306 and the suction pipe 304. The collection frame 320 is fixed to one side of the fixed plate 310, and the limiting triangular rod 313 fixed inside guides the chips to slide smoothly to the inlet of the suction pipe 304 to prevent blockage. After the chips enter the waste bin 309 with the airflow, they are intercepted by the filter plate 308, and the purified air is discharged, achieving timely cleaning of the chips and preventing the chips from accumulating in the cutting area and being carried up by the blade, causing secondary scratches or burrs.

[0068] Then, to keep the cutting blade 311 sharp at all times, the device is equipped with an online cleaning and grinding mechanism: the first cleaning brush 324 is fixed to one side of the collection frame 320, and the second cleaning brush 325 is fixed to one side of the fixing plate 310. The two are located on both sides of the cutting blade 311, and continuously contact its surface when the blade rotates at high speed to brush off the adhering chips. At the same time, a grinding frame 326 is fixedly connected to the side of the two sets of fixing plates 310 that are close to each other. The inner surface of the grinding frame 326 maintains slight contact with the outer surface of the cutting blade 311 and grinds it online when the blade rotates to maintain the sharpness of the cutting edge. This design enables the blade to maintain good cutting performance during long-term continuous cutting and reduces burrs and tears caused by tool dulling.

[0069] Finally, after the cutting blade 311 completely cuts the slide rail, the cut-off waste end is still held by the extrusion plate 312 and will not fall freely, causing bumps or scratches. The lifting plate 301 drives the cutting blade 311 to rise and reset. Then, the fourth electric push rod 328 releases the extrusion plate 312, and the waste end falls into the waste trough 220 under gravity and is discharged from the equipment through the waste trough 220. At the same time, the fan 321 continues to work to suck up the residual chips. The operator releases the locking of the insertion rod 208, lifts the n-shaped frame 205 upward, and releases the auxiliary clamping point to take out the processed slide rail. For the processing of the next slide rail, the above clamping, cutting, and cleaning steps are repeated to achieve continuous production.
