Description

Technical Field

[0001] This application relates to the field of filing tooling technology, and in particular to a special tooling for filing the bevel edge of a dishwasher housing. Background Technology

[0002] The shell of a hinged dishwasher is typically made of 304 stainless steel sheet, stamped and formed. Its edges need to be beveled at a specific angle to meet the requirements of subsequent welding or assembly processes. With the continuous growth of the dishwasher market, the mass production of the shell places increasingly higher demands on the efficiency, precision, and consistency of beveling. Currently, the processing of beveling edges on such thin sheets mainly relies on manual hand-held files and simple mechanical devices. However, manual filing depends entirely on the operator's experience and skill, which is not only labor-intensive and inefficient, but also makes it difficult to guarantee the consistency of bevel angle and depth. The quality of bevels varies significantly between different batches and even different locations on the same workpiece, failing to meet the quality control requirements of large-scale production. While simple mechanical devices improve processing efficiency to some extent, their simple structure and limited function, lacking precise control over feed rate and clamping force, result in unstable processing quality, making it difficult to meet the stringent precision requirements of thin sheet materials.

[0003] Existing mechanical filing devices employ a step-feed method, where the feed depth is adjusted manually or mechanically after each reciprocating stroke of the file. This intermittent feeding method results in uneven material removal thickness with each cut, drastic fluctuations in cutting force, and a tendency to create stepped tool marks on the bevel surface, making it difficult to control surface roughness within an ideal range. Furthermore, due to the poor rigidity of thin plates, the step-feed generates a large impact load at the moment of entry, easily causing localized deformation and chatter under the combined cutting and dragging forces. This not only affects the bevel machining accuracy but may also lead to irreversible plastic deformation at the edges of the thin plate, impacting subsequent assembly quality. In addition, the impact load of the step-feed accelerates file wear, shortening tool life. Moreover, during the return stroke, the file cannot completely detach from the workpiece surface, resulting in non-cutting contact and dragging between the file and the bevel, leaving scratches on the bevel surface, damaging the integrity of the machined surface, and in severe cases, even rendering the bevel unusable. At the same time, the return drag will also exacerbate the abnormal wear of the file, causing uneven wear on both sides of the file's cutting edge, further shortening the tool change cycle and increasing production costs. Summary of the Invention

[0004] Therefore, it is necessary to provide a special tooling for filing the bevel edge of the dishwasher housing to address the above-mentioned technical problems.

[0007] Preferably, the reciprocating mechanism includes a slide frame, two racks, a motor, and an incomplete gear. The slide frame is slidably connected in a third direction within the mounting base.

[0008] Preferably, the reset mechanism includes a slide groove, a lifting rod, a connecting seat, a stop block, and a spring.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows: By setting the moving end of the reciprocating mechanism to reciprocate along a third direction, the fixed end of the reset mechanism moves synchronously, thereby causing the moving end of the reset mechanism to drive the file to move synchronously along a third direction. When the file moves along the third direction with the moving end of the reciprocating mechanism, the follower end of the feed mechanism is displaced relative to the fixed end of the feed mechanism, thereby driving the file to continuously press down along a second direction, realizing continuous micro-feeding, so that the material layer removed by each filing is extremely thin, the filing force is stable and continuous, the surface roughness of the bevel is reduced, thereby improving the processing quality; at the same time, during the filing process, the file... The cutting force increases smoothly and linearly with the feed depth, which is less likely to induce chatter in thin plates, ensuring the consistency of the bevel shape and effectively suppressing local plastic deformation of thin plates during processing, thus ensuring the geometric accuracy of the thin plate edges. When the moving end of the reciprocating mechanism moves in the opposite direction along the third direction, the telescopic end of the reset mechanism moves in the opposite direction along the second direction, causing the file to lift up along the second direction, so that the file is separated from the workpiece. During the return stroke, the file is completely separated from the workpiece surface, avoiding non-filing contact between the file and the bevel being processed. This eliminates scratches on the bevel surface and file wear caused by dragging the file during the return stroke, realizing continuous micro-feeding and non-destructive retraction of the file in the reciprocating motion.

Detailed Implementation

[0014] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0015] like Figure 1-9 As shown, the specific implementation adopts the following technical solution: Example

[0016] A special tooling for filing the bevel edge of a dishwasher housing, including a body assembly 100; A filing assembly 200 is disposed on the body assembly 100 along a second direction. The filing assembly 200 includes a reciprocating mechanism 210, a reset mechanism 220, a file 230, and a feed mechanism 240. The driving end of the reciprocating mechanism 210 is disposed on the body assembly 100 along a first direction, and the moving end of the reciprocating mechanism 210 can reciprocate along a third direction. The fixed end of the reset mechanism 220 is disposed on the moving end of the reciprocating mechanism 210 and moves along the third direction with the moving end of the reciprocating mechanism 210. The telescopic end of the reset mechanism 220 can move along a second direction. The file 230 is disposed on the telescopic end of the reset mechanism 220 along the second direction. The fixed end of the feed mechanism 240 is disposed on the body assembly 100, and the follower end of the feed mechanism 240 is disposed on the surface of the file 230 along the second direction. The follower end of the feed mechanism 240 is used to move relative to the fixed end of the feed mechanism 240 and to drive the file 230 to move along the second direction. The machine body assembly 100 serves as the mounting base for the entire tooling, supporting and fixing the remaining components and providing stable foundation support for filing. The filing assembly 200 is used to form the bevel of the thin plate edge. The reciprocating mechanism 210 provides reciprocating motion power to the file 230 along a third direction. The reset mechanism 220 lifts the file 230 when the reciprocating mechanism 210 moves in the reverse direction along the third direction, so that the file 230 is removed from the workpiece surface, avoiding dragging damage during the return stroke. The file 230 is used to file the edge of the thin plate. The feed mechanism 240 drives the file 230 to continuously press down in the second direction when the file 230 moves in the forward direction along the third direction with the reciprocating mechanism 210, realizing single-pass filing feed. By setting the moving end of the reciprocating mechanism 210 to reciprocate along a third direction, the fixed end of the reset mechanism 220 is driven to move synchronously. This, in turn, causes the moving end of the reset mechanism 220 to drive the file 230 to move synchronously along a third direction. When the file 230 moves along the third direction with the moving end of the reciprocating mechanism 210, the follower end of the feed mechanism 240 is displaced relative to the fixed end of the feed mechanism 240, thereby driving the file 230 to continuously press down in the second direction. This achieves continuous micro-feeding, resulting in extremely thin material removal with each filing, stable and continuous filing force, and reduced surface roughness of the bevel, thus improving processing quality. Simultaneously, During the filing process, the filing force increases smoothly and linearly with the feed depth, which is not easy to induce chatter in thin plates and ensures the consistency of the bevel shape. When the moving end of the reciprocating mechanism 210 moves in the opposite direction along the third direction, the telescopic end of the reset mechanism 220 moves in the opposite direction along the second direction, driving the file 230 to lift in the second direction, so that the file 230 is separated from the workpiece. During the return stroke, the file 230 is completely separated from the workpiece surface, avoiding non-filing contact between the file 230 and the bevel being processed. This eliminates scratches on the bevel surface and wear on the file 230 caused by dragging the file 230 during the return stroke, and realizes continuous micro-feeding and non-destructive retraction of the file 230 in the reciprocating motion.

[0017] Specifically, the body assembly 100 includes a body 110, a drive frame 120, a fixed base 130, a motor 140, a rotating base 150, and a mounting base 160. The drive frame 120 is disposed on the surface of the body 110 along a second direction, and the output end of the drive frame 120 extends along the second direction. The fixed base 130 is fixedly mounted on the surface of the output end of the drive frame 120 along the second direction. The motor 140 is fixedly mounted on the surface of the fixed base 130 along a first direction, and the output shaft of the motor 140 extends out of the surface of the fixed base 130 along the first direction. The rotating base 150 is fixedly mounted on the surface of the output shaft of the motor 140 along the first direction and is rotatably connected to the surface of the fixed base 130 along the first direction. The mounting base 160 is fixedly mounted on the surface of the rotating base 150 along the second direction. The machine body 110 serves as the mounting base for the entire tooling, supporting and fixing the remaining components and providing a stable support foundation for the overall structure. The drive frame 120 supports the fixed seat 130 and other subsequent components on the machine body 110 and provides drive for the fixed seat 130 to move in the first direction and the second direction. The fixed seat 130 serves as the mounting carrier for the motor 140 and the rotating seat 150. The motor 140 provides a rotational power source to drive the rotating seat 150 to rotate around the first direction. The rotating seat 150 transmits the rotational motion of the motor 140 to the mounting seat 160, enabling angle adjustment of the mounting seat 160. The mounting seat 160 serves as the direct mounting base for the filing assembly 200.

[0018] Specifically, the reciprocating mechanism 210 includes a slide frame 211, two racks 212, a motor 213, and an incomplete gear 214. The slide frame 211 is slidably connected in the mounting base 160 along a third direction. The two racks 212 are sequentially arranged on the surface of the slide frame 211 along the second direction. The motor 213 is fixedly mounted on the surface of the mounting base 160 along the first direction. The output end of the motor 213 extends out of the surface of the mounting base 160 along the first direction. The incomplete gear 214 is fixedly mounted on the surface of the output end of the motor 213 along the first direction. The incomplete gear 214 meshes with one of the racks 212. By setting a sliding frame 211 as an actuator for reciprocating motion, it is used to slide back and forth along a third direction, driving the subsequent components to realize the reciprocating movement of the file 230. By setting two racks 212, they are used to alternately mesh with the incomplete gear 214, converting the rotational motion of the incomplete gear 214 into the linear reciprocating motion of the sliding frame 211. By setting a motor 213, it is used to provide rotational driving force for the incomplete gear 214. By setting the incomplete gear 214, it is used to convert the continuous rotational motion of the motor 213 into the reciprocating motion of the sliding frame 211.

[0019] Specifically, the reset mechanism 220 includes a slide groove 221, a lifting rod 222, a connecting seat 223, a stop block 224, and a spring 225. The slide groove 221 is formed on the surface of the mounting seat 160 along the second direction. The lifting rod 222 extends out of the slide groove 221 along the second direction and is fixedly mounted on the surface of the file 230 along the second direction. The connecting seat 223 is fixedly mounted on the surface of the slide frame 211 along the third direction and the lifting rod 222 extends out of the surface of the connecting seat 223 along the second direction. The stop block 224 is fixedly mounted on the surface of the lifting rod 222 along the second direction. The spring 225 is sleeved on the outside of the lifting rod 222 along the second direction. One end of the spring 225 is fixedly connected to the surface of the connecting seat 223 along the second direction, and the other end of the spring 225 is fixedly connected to the surface of the stop block 224 along the second direction. By setting a slide groove 221 as a guide channel for the lifting rod 222, the lifting rod 222 is used to transmit the reset force of the reset mechanism 220 to the file 230, driving the file 230 to reset in the second direction. By setting a connecting seat 223 for connection with the slide frame 211, the lifting rod 222 can drive the file 230 to reciprocate in the third direction. By setting a stop block 224 as a mounting base for the movable end of the spring 225, the spring 225 is compressed as the lifting rod 222 moves. The spring 225 is compressed and stores elastic potential energy when the file 230 is pressed down, and actively pulls the file 230 up in the second direction when the file 230 needs to be lifted.

[0020] Specifically, the feeding mechanism 240 includes a hanging base 241, a guide roller 242, and an inclined plate 243. The hanging base 241 is fixedly installed on the surface of the file 230 along the second direction. The guide roller 242 is disposed on the hanging base 241 along the second direction. The inclined plate 243 is fixedly installed on the surface of the mounting base 160 along the second direction. The inclined surface of the inclined plate 243 extends at an angle to the third direction. The guide roller 242 abuts against the inclined surface of the inclined plate 243. By setting up a hanger 241 as a mounting carrier for the guide roller 242, the guide roller 242 can move synchronously with the file 230 along a third direction. By setting up the guide roller 242 as a rolling follower, it is used to contact the inclined surface of the inclined plate 243 and roll along the inclined surface. By setting up the inclined plate 243 as a fixed inclined surface track, it is used to provide an inclined rolling path for the guide roller 242, so that the guide roller 242 generates displacement in a second direction when rolling in a third direction.

[0021] Specifically, it also includes a support assembly 300, which includes a frame 310, a guide rail 320, an elastic support mechanism 330, and a follower mechanism 340. The frame 310 is fixedly installed on the surface of the fixed base 130 along the first direction, the guide rail 320 is fixedly connected to the frame 310, the elastic support mechanism 330 is arranged on the guide rail 320 along the third direction, and the follower mechanism 340 is arranged on the hanger 241 along the second direction. The output end of the follower mechanism 340 can move along the second direction. By setting the frame 310 as the mounting base of the support component 300, the support component 300 as a whole is connected to the fixed base 130. By setting the guide rail 320, the elastic support mechanism 330 is installed. By setting the elastic support mechanism 330, the thin plate edge is elastically clamped. By setting the follower mechanism 340, the feed displacement of the file 230 along the second direction is converted into the adjustment of the elastic support mechanism 330. By setting the slide block 331 to slide along the third direction on the surface of the guide rail 320 and supporting the slide block 331 by the compression spring 334, when the support roller 336 contacts the edge of the thin plate, the slide block 331 is subjected to the reaction force of the thin plate, which is transmitted to the support block 332 through the compression spring 334, causing the support block 332 to slide along the guide rail 320. The compression spring 334 is compressed to generate an elastic clamping force, thereby forming elastic support and guidance for the edge of the thin plate, suppressing the deformation and vibration of the filing area when the file 230 files the thin plate, and ensuring the accuracy of the beveling process.

[0022] Specifically, the elastic support mechanism 330 includes a slide block 331, a support block 332, a guide rod 333, a compression spring 334, a support shaft 335, a support roller 336, and an inclined block 337. The slide block 331 is slidably connected to the surface of the guide rail 320 along a third direction, the support block 332 is slidably connected to the surface of the guide rail 320 along a third direction, and the guide rod 333 is fixedly connected to the surface of the slide block 331 along a third direction. The guide rod 333 extends through the surfaces of the slide block 331 and the support block 332 along a third direction. Spring 334 is sleeved on the outside of guide rod 333 along the third direction. One end of compression spring 334 is fixedly connected to the surface of slide block 331 along the third direction, and the other end of compression spring 334 is fixedly connected to the surface of support block 332 along the third direction. Support shaft 335 passes through the surface of slide block 331 along the second direction and is connected to slide block 331 through bearing. Support roller 336 is fixedly connected to the surface of support shaft 335 along the second direction, and inclined block 337 is fixedly connected to the surface of support block 332 along the second direction. By setting a slide block 331 as a movable base in the elastic support mechanism 330, and a support block 332 as a mounting base for the compression spring 334, the slide blocks 331 and 332 slide along the guide rail 320 under the drive of the follower mechanism 340. A guide rod 333 guides the movement of the slide block 331 and the support block 332 in a third direction. The compression spring 334 acts as an elastic energy storage element, ensuring the support roller 336 fits tightly against the edge of the thin plate. A support shaft 335 serves as the rotation axis of the support roller 336, allowing the support roller to move smoothly along the guide rail 320. Roller 336 can rotate freely around support shaft 335, reducing frictional resistance with the edge of the thin plate. By setting support roller 336 as a rolling element that directly contacts the edge of the thin plate, it is used to roll on the edge of the thin plate, forming elastic support and guidance for the edge of the thin plate, while avoiding sliding friction damage to the surface of the thin plate. By setting inclined block 337 as the drive interface of follower mechanism 340, it is used to receive the inclined thrust of wedge block 343 of follower mechanism 340, converting the driving force along the second direction into the sliding displacement of support block 332 along the third direction.

[0023] Specifically, the follower mechanism 340 includes a connecting plate 341, a guide groove 342, a wedge block 343, a connecting rod 344, and an arc strip 345. The guide groove 342 is formed on the surface of the frame 310 along a third direction. The connecting plate 341 extends out of the guide groove 342 along a third direction. The wedge block 343 is fixedly connected to the surface of the connecting plate 341 along a second direction. The wedge block 343 abuts against the inclined block 337. The connecting rod 344 is fixedly connected to the surface of the hanger 241 along a second direction. The arc strip 345 is fixedly connected to the surface of the connecting rod 344 along a first direction. The arc strip 345 abuts against the surface of the connecting plate 341 along a second direction. By setting the guide groove 342 as a guide channel for the connecting plate 341, the connecting plate 341 is restricted to moving only in the second direction, ensuring the stable and reliable movement trajectory of the connecting plate 341. By setting the connecting plate 341 as a mounting carrier and motion transmission element for the wedge block 343, the wedge block 343 is driven to move synchronously when moving in the second direction, transmitting the motion of the arc strip 345 to the wedge block 343. By setting the wedge block 343, the connecting plate 341 is moved along the straight line in the second direction through the contact between its inclined surface and the inclined block 337. The displacement is converted into the sliding displacement of the inclined block 337 along a third direction, realizing the conversion of the motion direction. By setting the connecting rod 344, the vertical movement of the hanging seat 241 is transmitted to the arc strip 345. By setting the arc strip 345, when the hanging seat 241 moves down, the arc surface presses down on the connecting plate 341, so that the connecting plate 341 moves down along the guide groove 342. And after the angle of the mounting seat 160 relative to the fixed seat 130 is adjusted, the distance between the connection position of the connecting rod 344 and the arc strip 345 and the connecting plate 341 remains unchanged. By setting up the connecting plate 341 and wedge 343, when the file 230 moves along the third direction with the reciprocating mechanism 210, the feed mechanism 240 drives the file 230 to move along the second direction. The hanging seat 241 moves down synchronously with the file 230. The connecting rod 344 drives the arc strip 345 to move synchronously. The arc strip 345 drives the connecting plate 341 to move along the second direction, so that the connecting plate 341 drives the wedge 343 to move synchronously. The inclined surface of the wedge 343 pushes the inclined block 337 to move along the third direction. The inclined block 337 drives the support block 332 to compress the compression spring 334, increasing the compression amount of the compression spring 334. In turn, the slide 331 and the support roller 336 apply a greater clamping force to the thin plate, realizing the filing... The deeper the feed depth of the cutter 230, the greater the clamping force of the support roller 336 on the thin plate. The increased clamping force can effectively resist the deformation and vibration of the thin plate caused by the filing process of the cutter 230, and improve the beveling accuracy and surface quality. When the cutter 230 moves in the opposite direction with the reciprocating mechanism 210, the hanger 241 drives the arc strip 345 to reset. The inclined block 337 and the support block 332 are reset under the rebound force of the compression spring 334. The clamping force is automatically reduced to reduce the resistance of the support roller 336 on the surface of the thin plate, making the support roller 336 move more smoothly and avoiding the support roller 336 getting stuck on the surface of the thin plate due to excessive clamping force, which would cause scratches. At the same time, it reduces the wear of the support roller 336.

[0024] Specifically, it also includes a clamping assembly 400, which includes a side plate 410, a cylinder 420 and a clamping plate 430. The side plate 410 is fixedly installed on the surface of the machine body 110 along the second direction. The cylinder 420 is fixedly installed on the surface of the side plate 410 along the third direction. The cylinder rod of the cylinder 420 extends out of the surface of the side plate 410 along the third direction. The end of the cylinder rod of the cylinder 420 is fixedly connected to the clamping plate 430. The side plate 410 serves as a mounting base for the cylinder 420, providing stable mounting support for the cylinder 420 and bearing the reaction force generated during clamping. The cylinder 420 serves as a power drive element, providing linear driving force along a third direction. The clamping plate 430 moves along a third direction under the drive of the cylinder 420, performing initial positioning of the thin plate. ； The specific implementation process of this application is as follows: First, the thin plate is placed between the two clamping plates 430 of the clamping assembly 400. The cylinder 420 drives the cylinder rod to extend, causing the clamping plates 430 to move along a third direction, thus clamping and fixing the thin plate. Then, the motor 140 is started, driving the output shaft to rotate the rotating seat 150 relative to the fixed seat 130 around the first direction. The rotating seat 150 drives the mounting seat 160 to rotate synchronously. The mounting seat 160 drives the file 230 on it to rotate as a whole, so that the angle of the file 230 is adjusted to the required bevel angle. ； Then, the drive frame 120 drives the output end to move along the first direction, causing the fixed seat 130 and all components mounted on it to move synchronously along the first direction until the file 230 and the support roller 336 reach the edge position of the thin plate along the first direction. The drive frame 120 further drives the output end to move along the second direction, causing the fixed seat 130 and the mounting seat 160 to move down along the second direction. The mounting seat 160 drives the elastic support mechanism 330 to move down as a whole, so that the support roller 336 moves down to the height of the thin plate edge. The thin plate edge is inserted between the two sets of support rollers 336 symmetrically arranged along the thin plate. The compression spring 334 applies an initial elastic clamping force to the support roller 336 through the slide 331 and the support shaft 335, so that the support roller 336 elastically clamps the thin plate edge. The drive frame 120 continues to fine-tune along the second direction, so that the file 230 moves along the second direction until the file 230 abuts against the surface to be processed on the edge of the thin plate, ready to start filing. The motor 213 is started, and the output shaft of the motor 213 drives the incomplete gear 214 to rotate continuously. The toothed section of the incomplete gear 214 alternately meshes with the two racks 212 on the slide frame 211: when the toothed section meshes with the first rack 212, it pushes the slide frame 211 to move forward along the third direction; when the toothed section meshes with the second rack 212, it pushes the slide frame 211 to move backward along the third direction, so that the slide frame 211 reciprocates within the mounting base 160. The reciprocating movement of the slide frame 211 along the third direction drives the connecting base 223 to move synchronously. The connecting base 223 drives the file 230 to reciprocate synchronously along the third direction through the hanging rod 222, so that the file 230 reciprocates synchronously along the third direction. Simultaneously, the hanging base 241 moves synchronously with the file 230 along the third direction. The hanging base 241 drives the guide roller 242 to roll along the inclined plane of the fixed inclined plate 243. When the file 230 moves in the positive direction along the third direction, the guide roller 242 moves along the inclined plane and generates movement in the second direction. The hanging base 241 drives the file 230 to continuously press down in the second direction, realizing continuous micro-feeding. During this process, the lifting rod 222 moves along the second direction and drives the stop block 224 to move, thereby compressing the spring 225. When the file 230 moves in the reverse direction along the third direction, the guide roller 242 moves up along the inclined plane, and the file 230 loses the downward driving force. Under the elastic force of the spring 225, the stop block 224 and the lifting rod 222 drive the file 230 to lift up in the second direction, completely detaching it from the workpiece surface, realizing non-destructive retraction. Throughout the filing process, the support roller 336 always stays close to and rolls on the edge of the thin plate. The compression spring 334 applies an elastic clamping force to the support roller 336 through the slide block 331 and the support shaft 335, so that the support roller 336 elastically presses the edge of the thin plate, suppresses the deformation and vibration of the thin plate in the filing area, and ensures the beveling accuracy. When the file 230 presses down in the second direction, the hanging seat 241 moves synchronously with the file 230, driving the connecting rod 344 and the arc strip 345 to move synchronously in the second direction. The arc strip 345 presses down on the connecting plate 341, causing the connecting plate 341 to move along the guide groove 342, driving the wedge block 343 to move synchronously in the second direction. The inclined surface of the wedge block 343 pushes the inclined block 337 to move in the third direction. The inclined block 337 drives the support block 332 to slide towards the slide block 331 to compress the compression spring 334, increasing the compression amount of the compression spring 334. Through the slide block 331 and the support shaft 335, a greater elastic thrust is applied to the support roller 336, increasing the clamping force. The deeper the file 230 feeds, the greater the clamping force, forming a positive feedback adaptive clamping, effectively resisting the deformation and vibration of the thin plate caused by the cutting force. When the file 230 moves in the opposite direction along the third direction, the guide roller 242 moves upward along the inclined plane, and drives the arc strip 345 to move upward through the connecting rod 344. The arc strip 345 leaves the connecting plate 341, and the compression spring 334 resets, causing the support block 332 to reset, which in turn causes the connecting plate 341 and the wedge block 343 to reset. The compression amount of the compression spring 334 decreases, the clamping force returns to the initial value, reduces the rolling resistance of the support roller 336, and avoids scratching the surface of the thin plate. By setting up the connecting plate 341 and wedge 343, when the file 230 moves along the third direction with the reciprocating mechanism 210, the feed mechanism 240 drives the file 230 to move along the second direction. The hanging seat 241 moves down synchronously with the file 230. The connecting rod 344 drives the arc strip 345 to move synchronously. The arc strip 345 drives the connecting plate 341 to move along the second direction, so that the connecting plate 341 drives the wedge 343 to move synchronously. The inclined surface of the wedge 343 pushes the inclined block 337 to move along the third direction. The inclined block 337 drives the support block 332 to compress the compression spring 334, increasing the compression amount of the compression spring 334. In turn, the slide 331 and the support roller 336 apply a greater clamping force to the thin plate, realizing the filing... The deeper the feed depth of the cutter 230, the greater the clamping force of the support roller 336 on the thin plate. The increased clamping force can effectively resist the deformation and vibration of the thin plate caused by the filing process of the cutter 230, and improve the beveling accuracy and surface quality. When the cutter 230 moves in the opposite direction with the reciprocating mechanism 210, the hanger 241 drives the arc strip 345 to reset. The inclined block 337 and the support block 332 are reset under the rebound force of the compression spring 334. The clamping force is automatically reduced to reduce the resistance of the support roller 336 on the surface of the thin plate, making the support roller 336 move more smoothly and avoiding the support roller 336 getting stuck on the surface of the thin plate due to excessive clamping force, which would cause scratches. At the same time, it reduces the wear of the support roller 336.
