Description

Technical Field

[0001] The invention relates to the technical field of sheet metal processing equipment, in particular to a sheet metal processing fixture. Background Art

[0002] Sheet metal is a comprehensive cold processing technology for thin metal plates, including shearing, punching, cutting, compounding, folding, riveting, splicing and forming. Its most notable feature is that the thickness of the same part is consistent. The fixture is a process device used to quickly fasten the workpiece during processing to keep the machine tool, cutting tool and workpiece in the correct relative position; that is to say, tooling fixtures are indispensable parts of mechanical processing. When performing sheet metal processing, fixtures are needed to fix sheet metal parts.

[0003] However, in traditional sheet metal processing, after the sheet metal parts are clamped and fixed by clamps, it is inconvenient to move the position of the sheet metal parts. At the same time, the sheet metal parts are clamped on both sides of the sheet metal by single clamps, which easily causes longer or more stacked sheet metal parts to shift, resulting in poor sheet metal processing effects. Traditional sheet metal processing requires alignment of both ends of the sheet metal parts, and the efficiency of aligning both ends of the sheet metal parts at a single station is low. At the same time, the positions of the alignment components before and after alignment affect the loading and unloading of the sheet metal by the robot, affecting the sheet metal processing efficiency. When sheet metal processing and when the workbench is purged and cleaned after processing, a large amount of metal scraps are easily generated, and the scraps are easily splashed onto the screw and slide rails of the feeding and alignment components, resulting in large wear and tear on the subsequent equipment and uneven operation.

[0025] When the present invention is used, first, when sheet metal needs to be processed, multiple stacked sheet metals are placed on the front end of the processing seat 201 by a manipulator, and then the multiple stacked sheet metals are aligned by the alignment structure 4, and then the first hydraulic rod 203 on the fixed plate 202 is started, and the first hydraulic rod 203 is extended to drive the first clamping plate 204 and the first clamping block 205 to move toward the sheet metal, and the first clamping block 205 cooperates with the second clamping block 210 to clamp the sheet metal, and then the first motor 211 and the first hydraulic rod 203 are started at the same time, and the first motor 211 is started. 11 drives the first pulley 212 to rotate, the first pulley 212 drives the second pulley 213 to rotate through the belt, the second pulley 213 drives the first screw 207 to rotate, the first screw 207 rotates to drive the slide 208 to move, the slide 208 drives the connecting frame 209 to move, the connecting frame 209 drives the second clamping block 210 to move, the first hydraulic rod 203 contracts to drive the first clamping block 205 to move, the first clamping block 205 and the second clamping block 210 move synchronously, and then drive the sheet metal to move to the upper side of the lower clamping plate 219 The second hydraulic rod 216 is then started, and the second hydraulic rod 216 is extended to drive the connecting bar 217 to rise, thereby driving the lifting plate 218 to rise, and the lifting plate 218 rises and drives the lower clamping plate 219 to rise, and the lower clamping plate 219 rises and drives the sheet metal to rise and fully contact the upper clamping plate 215, and then the first motor 211 is started, so that the first motor 211 drives the first pulley 212 to reverse, thereby driving the second pulley 213 and the first screw 207 to reverse, so that the second clamping block 210 moves to the initial position, and at the same time the first The hydraulic rod 203 contracts to drive the first clamping block 205 to reset, and then the sheet metal part is processed by the processing machine tool for rough milling and fine milling. After the processing is completed, the processing table 1, the processing seat 201, and the front and rear upper and lower clamps are cleaned and purged by the machine tool to prevent processing waste from adhering to the first clamping block 205, the second clamping block 210, the upper clamping plate 215, and the lower clamping plate 219. The setting of the protective cover 214 prevents processing waste from falling on the first screw 207 during processing or cleaning and purging, which affects the normal use of the first screw 207 in the subsequent process. Then, when the sheet metal needs to be aligned, the manipulator moves away. At this time, the second motor 306 on the fixed table 302 can be started, and the second motor 306 drives the second screw 305 to rotate. The second screw 305 rotates to drive the first threaded sleeve 310 to move. The first threaded sleeve 310 moves to drive the moving table 309 to move, and then the alignment structure 4 is moved to the station where the sheet metal is to be processed. When the moving table 309 moves, it drives the supporting foot 308 and the slider 307 to move on the slide rail 303, thereby improving The third motor 401 is then started, the third motor 401 drives the third pulley 402 to rotate, the third pulley 402 rotates and then drives the fourth pulley 404 to rotate through the belt, the fourth pulley 404 drives the third screw 405 to rotate, the third screw 405 rotates and then drives the second threaded sleeve 406 to move forward and backward, the second threaded sleeve 406 drives the slide 407 to move on the guide rail 403, and the slide 407 drives the slide plate 407 when moving on the guide rail 403. 8 moves, the slide plate 408 moves and drives the alignment clamping plate 417 at the end to move to the two ends of the sheet metal part, and then the fourth motor 409 is started, the fourth motor 409 drives the fifth pulley 410 to rotate, the fifth pulley 410 rotates and drives the sixth pulley 412 to rotate through the belt, and the sixth pulley 412 drives the fourth screw 413 to rotate. Since the threads at both ends of the fourth screw 413 are in opposite directions, the rotation of the fourth screw 413 can drive the two third threaded sleeves 414 to move toward or away from each other. When the two third threaded sleeves 414 move toward each other, they drive the connecting rod 415 to slide on the limiting plate 416. At the same time, the connecting rod 415 drives the two alignment clamping plates 417 to align the two ends of the sheet metal part, thereby avoiding the problem of low alignment at both ends of the sheet metal part during processing. After the alignment is completed, the sheet metal is clamped by the clamping structure 2, and then the third motor 401 is driven to reset the slide plate 408, and then the second motor 306 is driven to move the moving platform 309 to another station to align the placed sheet metal part. Finally, when the movable table 309 drives the guide rail 403 to move, it drives the second rack 611 to move, the second rack 611 moves and drives the second gear 610 to rotate, the second gear 610 rotates and drives the shaft 605 to rotate, the shaft 605 rotates and drives the first gear 606 to rotate, the first gear 606 rotates and drives the first rack 607 at one end to rise, and the first rack 607 at the other end to fall, the first rack 607 rises and falls and drives the baffle 608 to rise and fall, the setting of the guide rod 609 improves the stability of the baffle 608 sliding up and down, and when the movable table 309 moves to the sheet metal work station to be processed, the sheet metal work being processed The baffle 608 in front of the sheet metal workstation rises, and the cutting waste and splashing coolant generated by the processing are blocked by the baffle 608, so that the liquid and waste naturally fall into the collection box 503, and the liquid flows out after being filtered by the filter screen 504, and the waste is collected by the collection box 503. At the same time, the collection box 503 also collects and blocks the cleaning liquid and waste flowing down when cleaning the processing seat 201, so as to prevent the waste from being blown onto the second screw 305 and the slide rail 303 during the processing and cleaning process, affecting the subsequent use. The ratio of the left and right movement of the movable table 309 to the up and down movement of the baffle 608 is equal to the ratio of the second gear 610 to the first gear 610. 06, and the first gear 606 and the second gear 610 are staggered front and back to avoid the baffle 608 affecting the left and right movement of the guide rail 403 and the moving platform 309 when the baffle 608 is raised and lowered. When there are a lot of waste scraps collected in the collection box 503 that need to be processed, the fifth screw 603 can be rotated by the hexagonal wrench. The rotation of the fifth screw 603 drives the lifting block 602 to descend at the vertical plate 601, and then drives the mounting block 604 to descend, so that the second gear 610 is no longer engaged with the second rack 611. The limit rod 506 can be pulled, and the limit rod 506 drives the spring 507 to be compressed, and at the same time, it is no longer engaged with the limit rod on the plug plate 501. The positioning hole 508 is engaged, and the collection box 503 can be slid out from the side of the plug plate 501 away from the block 502, and then the waste chips inside can be cleaned, so as to facilitate the centralized treatment of some of the waste chips generated during processing. The cleaned collection box 503 can then be reinserted. After the collection box 503 contacts the block 502, the limit rod 506 can be loosened, and the spring 507 is reset to drive the limit rod 506 to engage with the limit hole 508 on the plug plate 501, and then the fifth screw 603 is rotated with the hexagonal wrench to make the mounting block 604 rise, thereby driving the second gear 610 to re-engage with the second rack 611 at the bottom of the guide rail 403.
