Description

Technical Field

[0001] This utility model relates to the field of horizontal machining center technology, specifically to an intelligent workpiece clamping system for horizontal machining centers. Background Technology

[0002] In the field of machining, horizontal machining centers are often used for machining complex parts due to their ability to perform multi-faceted machining, playing a crucial role in precision manufacturing. Traditional horizontal machining centers mostly employ a closed structure, where a protective door encloses the workpiece inside the equipment during machining to prevent metal chips from flying during high-speed processing.

[0003] However, the fixtures in such machining centers are typically located within the machining chamber. When clamping a workpiece, the operator must extend their body into the machining chamber, where the limited operating space makes workpiece clamping inconvenient. This not only reduces workpiece clamping efficiency but also increases the operator's workload. In some cases, due to the inconvenience, the accuracy of workpiece clamping may be affected, consequently impacting the machining accuracy of the workpiece.

[0004] Chinese patent (authorization announcement number: CN 115319508 B, authorization announcement date: 2023.01.06) proposes a horizontal machining center that facilitates workpiece clamping. This patent uses a drive component in conjunction with the opening and closing of a protective door to move the clamping assembly. When the protective door is open, the clamping assembly is located on the outside and exposed, eliminating the need for operators to extend their bodies into the equipment and providing a large operating space for workpiece clamping. When the protective door is closed, the clamping assembly is located inside the equipment, facilitating workpiece processing.

[0005] While this patent allows the fixture assembly to be moved outside the machining chamber, greatly facilitating workpiece clamping, its transmission components such as gears and screws are completely exposed. During the operation of the horizontal machining center, metal chips fly everywhere, easily getting stuck in the gaps between these parts, hindering the smooth movement of the fixture assembly, causing interruptions in the clamping process, and affecting machining efficiency and accuracy. To effectively avoid interference from metal chips during machining while enabling convenient removal of the fixture from the machining chamber for workpiece clamping, we propose an intelligent workpiece clamping system for horizontal machining centers.

[0025] 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.

[0026] Please see Figure 1-6 This utility model provides a technical solution: an intelligent workpiece clamping system for a horizontal machining center, including a machine body 1, two sets of protective doors 2 are provided on the front side of the machine body 1, an installation cover 3 is fixedly connected to the front side of the machine body 1, an installation platform 4 is provided in the machine body 1, several sets of slide rails 5 are fixedly connected to the top of the installation platform 4, a clamping platform 6 is slidably installed on the slide rails 5, a clamping component for clamping workpieces is installed on the clamping platform 6, and a moving component for moving the clamping platform 6 is installed on the installation cover 3;

[0027] The movable component includes a protective cover 9, which is fixedly connected to the top of the mounting cover 3. A threaded sleeve 12 is rotatably inserted through the protective cover 9, and a screw 14 is threaded through the threaded sleeve 12. A connecting block 15 is fixedly connected to the bottom of the clamping table 6. The rear end of the screw 14 is fixedly connected to the connecting block 15. A sliding cover 16 is fixedly connected to the rear side of the protective cover 9. A connecting cover 13 is slidably connected to the inner wall of the sliding cover 16. The end of the connecting cover 13 away from the sliding cover 16 is fixedly connected to the connecting block 15. A drive mechanism for driving the threaded sleeve 12 to rotate is installed on the mounting cover 3.

[0028] In use, the drive mechanism rotates the threaded sleeve 12, which in turn moves the connecting block 15 back and forth via the screw 14, thus moving the clamping table 6 back and forth. This allows the clamping table 6 to be moved out of the machining chamber of the machine body 1 when clamping is required. The clamping assembly is then used to clamp the workpiece, eliminating the need for operators to extend their bodies into the machining chamber, improving workpiece clamping efficiency and reducing operator workload. Furthermore, the protective cover 9, sliding cover 16, and connecting cover 13 effectively prevent metal chips generated during machining from interfering with the movement process, ensuring a smooth clamping procedure.

[0029] The drive mechanism includes two sets of mounting blocks 26, which are slidably connected to the inner wall of the mounting cover 3. A toothed plate 7 is fixedly connected to one side of each set of mounting blocks 26 that is close to each other. A rotating rod 20 is rotatably mounted on the mounting cover 3. A rotating gear 21 is fixedly connected to the bottom of the rotating rod 20 and meshes with the toothed plate 7. A driving bevel gear 10 is fixedly connected to the top of the rotating rod 20. A driven bevel gear 11 is fixedly connected to the end of the threaded sleeve 12 near the driving bevel gear 10. The driving bevel gear 10 and the driven bevel gear 11 mesh. A drive cylinder 8 is fixedly mounted on the inner wall of the mounting cover 3. A transmission block 27 is fixedly connected to the output end of the drive cylinder 8. The top of the transmission block 27 is fixedly connected to one of the sets of mounting blocks 26. An opening and closing mechanism for driving the protective door 2 to open and close is mounted on the mounting cover 3.

[0030] When the start-up drive cylinder 8 moves the transmission block 27, the mounting block 26 moves, which in turn moves the gear plate 7. The movement of the gear plate 7 causes the rotating gear 21 to rotate, which in turn causes the drive bevel gear 10 to rotate via the rotating rod 20. This causes the driven bevel gear 11 to rotate, which in turn drives the threaded sleeve 12 to rotate.

[0031] The opening and closing mechanism includes two sets of sliding blocks 25. The mounting cover 3 has two sets of sliding openings that match the sliding blocks 25. The sliding blocks 25 are slidably connected to the sliding openings. The tops of the two sets of sliding blocks 25 are fixedly connected to the two sets of protective doors 2 respectively. The bottoms of the two sets of sliding blocks 25 are fixedly connected to the two sets of mounting blocks 26 respectively.

[0032] When one set of toothed plates 7 moves and drives the rotating gear 21 to rotate, the rotation of the rotating gear 21 causes another set of toothed plates 7 to move, causing the two sets of mounting blocks 26 to move closer or further apart. Under the connection of the sliding block 25, the two sets of protective doors 2 are opened and closed, so that when clamping is required, the two sets of protective doors 2 are opened to facilitate the removal of the clamping table 6. When processing is required after clamping, the two sets of protective doors 2 are closed to prevent metal chips from flying and protect the safety of the operator.

[0033] The clamping assembly includes two clamping cylinders 24, which are fixedly installed on the top of the clamping table 6. The two clamping cylinders 24 are arranged symmetrically. The output end of the clamping cylinder 24 is fixedly connected to a pressure plate 19. Anti-slip buffer pads are provided on the side of the two pressure plates 19 that are close to each other. A stabilizing mechanism to prevent the workpiece from shaking is installed on the pressure plate 19.

[0034] Start the clamping cylinder 24 to drive the two sets of pressure plates 19 to move closer to each other, clamping and fixing the workpiece between the two sets of pressure plates 19, thus completing the clamping.

[0035] The stabilizing mechanism includes two sets of lifting covers 18. The lifting covers 18 are fixedly installed on the pressure plate 19. An L-shaped plate 17 is slidably connected to the inner wall of the lifting cover 18. Several sets of mounting plates 22 are fixedly connected to the side of the lifting cover 18 and the L-shaped plate 17 near the clamping cylinder 24. A spring 23 is fixedly installed between two sets of mounting plates 22. A positioning mechanism that can fix the position of the L-shaped plate 17 is installed on the lifting cover 18.

[0036] The positioning mechanism includes a limiting screw 28, which is rotatably mounted on the lifting cover 18. An L-shaped plate 17 has a movable groove corresponding to the limiting screw 28. The limiting screw 28 is movably connected to the movable groove. A limiting block 29 is slidably mounted on the lifting cover 18. The limiting screw 28 is threaded through the limiting block 29.

[0037] Rotating the limiting screw 28 causes the limiting block 29 to slide on the lifting cover 18. When the limiting block 29 is pressed tightly against the L-shaped plate 17, the L-shaped plate 17 cannot move, thus fixing its position. During clamping, first fix the L-shaped plate 17 at a position higher than the workpiece to avoid affecting the movement of the pressure plate 19. After clamping, release the L-shaped plate 17. Under the action of the spring 23, the L-shaped plate 17 will be pressed tightly against the top of the workpiece. At this time, fix the L-shaped plate 17 again. The L-shaped plate 17 can further restrict the position of the workpiece and prevent it from shaking. The clamping process is simple and reliable.

[0038] Working Principle: During operation, the drive cylinder 8 moves the transmission block 27, which in turn moves the mounting block 26, causing the gear plate 7 to move. The gear plate 7's movement causes the rotating gear 21 to rotate, which in turn rotates the driving bevel gear 10 via the rotating rod 20. This, in turn, rotates the driven bevel gear 11, causing the threaded sleeve 12 to rotate. The screw 14 then moves the connecting block 15 back and forth, which in turn moves the clamping table 6 back and forth. When clamping is required, the clamping table 6 can be moved out of the machining chamber of the machine body 1. After placing the workpiece on the clamping table 6, the clamping cylinder 24 is activated, causing the two sets of pressure plates 19 to move closer together, clamping and fixing the workpiece between the two sets of pressure plates 19, thus completing the clamping process. Operators no longer need to extend their bodies into the machining chamber of the equipment, improving workpiece clamping efficiency and reducing operator workload. Furthermore, the protective cover 9, sliding cover 16, and connecting cover 13 effectively prevent metal chips generated during processing from interfering with the movement process, ensuring a smooth clamping procedure. During this process, when one set of toothed plates 7 moves, driving the rotating gear 21 to rotate, the rotation of the rotating gear 21 causes another set of toothed plates 7 to move, causing the two sets of mounting blocks 26 to move closer or further apart. Under the connecting action of the sliding block 25, the two sets of protective doors 2 are opened and closed, so that when clamping is required, the two sets of protective doors 2 open to facilitate the removal of the clamping table 6. After clamping is completed and processing is required, the two sets of protective doors 2 close to prevent metal chips from flying and protect the safety of the operator. Rotating the limit screw 28 can drive the limit block 29 to slide on the lifting cover 18. When the limit block 29 is pressed tightly on the L-shaped plate 17, the L-shaped plate 17 cannot move, thus fixing the position of the L-shaped plate 17. During clamping, first fix the L-shaped plate 17 at a position higher than the workpiece to avoid affecting the movement of the pressure plate 19. After clamping, loosen the L-shaped plate 17. Under the action of the spring 23, the L-shaped plate 17 is tightly attached to the top of the workpiece. At this time, fix the L-shaped plate 17 again. The position of the workpiece can be further restricted by the L-shaped plate 17 to prevent the workpiece from shaking. The clamping process is simple and reliable.
