Description

Technical Field

[0001] This invention relates to the field of end-positioning technology, specifically to an end-positioning device for a five-axis linkage machining center. Background Technology

[0002] A five-axis machining center is a high-tech, high-precision machining center used for machining workpieces with complex curved surfaces. It has five axes: x, y, z, a, and c. These axes work together in a five-axis linkage, making it adept at machining spatial curved surfaces, irregular shapes, hollowing, drilling, angled holes, and beveling. By aligning the machining end face of the workpiece sequentially with the positions of the machining axes, the workpiece can be fully machined with a single clamping operation.

[0003] In existing five-axis machining centers, the degree of automation is high. A five-axis machining center mainly includes a worktable, a spindle head, a workpiece feed system, and a CNC system. The worktable serves as the mounting base for the five-axis machining center, supporting and mounting multiple devices. The spindle head includes a tool drive device and a tool changing system, which enables the corresponding tool to complete the machining operation on the corresponding end face of the workpiece. The workpiece feed system is used to clamp the workpiece and move the workpiece along the x, y, z, a, and c axes, allowing different end faces of the workpiece to cooperate with the corresponding tools. The CNC system programs and controls the drive data of the entire five-axis machining center, enabling the various devices in the five-axis machining center to work together.

[0004] Because the workpiece feed system needs to move the workpiece at multiple angles, after completing the machining of the last end face of the workpiece, the workpiece feed system and the workpiece maintain a sufficient machining angle. However, when the workpiece feed system is reset and the workpiece is replaced again, the continuity of the machining process of multiple workpieces is poor. Furthermore, restarting after adjusting the workpiece will increase the tool change frequency. Summary of the Invention

[0005] This invention proposes an end-positioning device for a five-axis linkage machining center, which solves the problem of poor continuity in the machining of multiple workpieces in the prior art because each workpiece needs to be processed on multiple end faces, requiring the workpiece feed system to reset the workpiece.

[0006] The technical solution of the present invention is as follows: an end-positioning device for a five-axis linkage machining center, comprising a loading robotic arm, wherein the number of loading robotic arms is set to two, and further comprising:

[0007] The mounting frame has two loading robotic arms respectively located on both sides of the mounting frame. Multiple sliding frames are fixedly connected to the mounting frame. Sliding grooves are slidably connected within the sliding frames. An end face adjustment structure is provided within the sliding grooves. A workpiece fixing structure is provided on the end face adjustment structure.

[0008] A sequential driving mechanism is disposed between multiple sliding frames and is movably mounted on the mounting frame. The sequential driving mechanism is used to sequentially drive multiple end face adjustment structures to adjust the position of the workpiece fixing structure.

[0009] To further adjust the position and angle of the clamped workpiece, the end face adjustment structure includes an arc-shaped slide rail, a rotating shaft, and a spherical groove. The arc-shaped slide rail is fixedly connected to the sliding groove, and a sliding seat is slidably connected to the arc-shaped slide rail. The rotating shaft is rotatably connected through the sliding groove, and the center point of the rotating shaft corresponds to the center point of the arc-shaped slide rail. The rotating shaft is fixedly connected to the sliding seat, and the spherical groove is formed on the sliding seat. An arc-shaped groove is formed inside the spherical groove, and a spherical seat is slidably connected to the arc-shaped groove. A fixing rod is fixedly connected to the top of the spherical seat, and a pushing structure is provided between the fixing rod and the sliding groove.

[0010] To enable the fixed rod to slide along the inner wall of the arc-shaped groove, the pushing structure further includes a rotating seat, on which the rotating seat is mounted, and on which a drive electric cylinder is mounted. The output end of the drive electric cylinder is rotatably connected to the fixed rod via a rotating shaft.

[0011] In order to clamp the workpiece being processed, the workpiece fixing structure further includes a fixing platform and clamping components. The fixing platform is fixedly connected to the top end of the fixing rod, and the number of clamping components is set to multiple. A rotation reset assembly is provided between the clamping components and the fixing platform.

[0012] To ensure stable clamping of the workpiece by the clamping component, the rotation reset assembly further includes a rotating component, which is fixedly connected to the fixed platform. A mounting shaft is rotatably connected to the rotating component, and the clamping component is fixedly connected to the mounting shaft. A spring is provided between the rotating component and the mounting shaft.

[0013] In order to adjust the angles of multiple sliding seats in sequence, the sequential driving mechanism further includes a movable slide groove and a transmission drive belt. The transmission drive belt is driven in the movable slide groove through a transmission structure. A friction section is provided on the outer arc surface of the transmission drive belt. A friction ring is fixedly sleeved on the rotating shaft.

[0014] To drive the drive belt to move cyclically, the transmission structure further includes a drive shaft and a first drive motor. Multiple drive shafts are rotatably connected in the moving slide, and drive wheels are provided on the drive shafts. The drive belt is driven between the multiple drive wheels. The first drive motor is provided on the moving slide, and the output end of the first drive motor is fixedly connected to one of the drive shafts.

[0015] To further facilitate the movement of the movable slide rail, the system also includes a movable slide rail, a transmission screw, and a second drive motor. The movable slide rail is fixedly connected to multiple sliding frames, the movable slide rail is slidably connected to the movable slide rail, the transmission screw is rotatably connected to the movable slide rail, the movable slide rail is threadedly connected to the transmission screw, the second drive motor is mounted on the movable slide rail, and the output end of the second drive motor is fixedly connected to the transmission screw.

[0016] To facilitate the movement of multiple sliding grooves within the sliding frame, the system further includes transverse slide rails, connectors, a rotating screw, and a third drive motor. Transverse slide rails are provided on both sides of the mounting frame. Connectors are fixedly connected between the multiple sliding grooves. Each connector is slidably connected between two transverse slide rails. A rotating screw is rotatably connected to one of the transverse slide rails and threadedly connected to the connector. The third drive motor is located on one of the transverse slide rails, and its output end is fixedly connected to the rotating screw.

[0017] To temporarily place the processed workpieces, the system further includes a receiving box, a rotating seat, and a sloped pusher. The rotating seat is provided on the inner bottom wall of the sliding frame, and a support plate is rotatably connected to the rotating seat. The receiving box is fixedly connected to one side of the support plate, and the sloped pusher is fixedly connected to the other side of the support plate. The sloped pusher is in contact with the sliding groove.

[0018] The working principle and beneficial effects of this invention are as follows:

[0019] 1. In this invention, when multiple workpieces need to be processed sequentially, after the last end face of the workpiece on the workpiece feeding system is processed, multiple workpieces are placed sequentially in multiple sliding grooves, and the multiple sliding grooves are pushed to move within the sliding frame, moving the unprocessed workpiece to the side closer to the loading robot arm. After the workpiece feeding system adjusts the final processing angle of the workpiece, the sequential drive mechanism is moved to one of the end face adjustment structures. Through the cooperation of the sequential drive mechanism and the push structure, the angle of the workpiece held in the workpiece fixing structure is adjusted so that the tilt angle of the held workpiece is consistent with the tilt angle of the workpiece being processed on the workpiece feeding system. This allows the loading robot arm to directly replace two workpieces, and also allows the workpiece feeding system to hold the unprocessed workpiece when position adjustment is required. At this time, it is not necessary to change the processing tool on the spindle box, and the new workpiece can be processed directly, effectively improving the continuity of processing multiple workpieces.

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0030] like Figures 1 to 7 As shown, this embodiment proposes an end-positioning device for a five-axis linkage machining center, including a loading robot arm 1. The number of loading robot arms 1 is set to two. The five-axis linkage machining center is a common complex curved surface machining equipment in the prior art, and is a prior art equipment known to those skilled in the art. The workpiece feeding system 36 on the five-axis linkage machining center is a prior art equipment that can automatically clamp the workpiece and can complete the clamping and angle adjustment of the workpiece.

[0031] It also includes a mounting frame 2, with two feeding robotic arms 1 respectively positioned on both sides of the mounting frame 2. Multiple sliding frames 3 are fixedly connected to the mounting frame 2, and sliding grooves 4 are slidably connected within the sliding frames 3. Each sliding groove 4 has an end-face adjustment structure, which includes an arc-shaped slide rail 5, a rotating shaft 7, and a spherical groove 8. The arc-shaped slide rail 5 is fixedly connected to the sliding groove 4, and a sliding seat 6 is slidably connected to it. A rotating shaft 7 is rotatably connected through the sliding groove 4, with the center point of the rotating shaft 7 corresponding to the center point of the arc-shaped slide rail 5. The rotating shaft 7 is fixedly connected to the sliding seat 6, and the sliding seat 6 has a spherical groove 8. An arc-shaped groove is formed inside the spherical groove 8. A spherical seat 9 is slidably connected to the arc-shaped groove. A fixing rod 10 is fixedly connected to the top of the spherical seat 9. A pushing structure is provided between the fixing rod 10 and the sliding groove 4. When the rotating shaft 7 is driven to rotate, the sliding seat 6 and multiple components on the sliding seat 6 slide together along the inner wall of the arc-shaped slide rail 5. The position of the sliding seat 6 is adjusted first. The rotating shaft 7 and the sliding groove 4 maintain sufficient damping so that after the rotating shaft 7 stops rotating, the rotating shaft 7 will not move arbitrarily due to the contact between the rotating shaft 7 and the sliding groove 4. Thus, the initial adjustment of the angle of the clamped workpiece is completed.

[0032] The pushing structure includes a rotating seat 11, which is mounted on a sliding seat 6. A drive electric cylinder 12 is mounted on the rotating seat 11. The output end of the drive electric cylinder 12 is rotatably connected to the fixed rod 10 via a rotating shaft 13. Then, the drive electric cylinder 12 is activated to drive the fixed rod 10 and the spherical seat 9 to move together in the spherical groove 8, so that the spherical seat 9 moves along the inner wall of the arc groove, making the tilt angle of the workpiece consistent with the tilt angle of the workpiece clamped on the workpiece feeding system 36.

[0033] The end face adjustment structure is provided with a workpiece fixing structure, which includes a fixing platform 14 and clamping parts 15. The fixing platform 14 is fixedly connected to the top of the fixing rod 10. The number of clamping parts 15 is set to multiple. A rotation reset assembly is provided between the clamping parts 15 and the fixing platform 14. The unprocessed workpiece can be placed at the bottom of the fixing platform 14, and the multiple clamping parts 15 are in contact with the top of the workpiece.

[0034] The rotation reset assembly includes a rotating component 16, which is fixedly connected to the fixed platform 14. A mounting shaft 17 is rotatably connected to the rotating component 16, and a clamping component 15 is fixedly connected to the mounting shaft 17. A spring-loaded spring 18 is provided between the rotating component 16 and the mounting shaft 17. In order to ensure stable clamping of the workpiece and facilitate the loading robot arm 1 to directly remove the workpiece from among the multiple clamping components 15, the clamping component 15 in this invention can rotate on the rotating component 16 together with the mounting shaft 17. During the rotation of the mounting shaft 17, the spring-loaded spring 18 will generate rotational torque on the mounting shaft 17. After the workpiece is removed, the spring-loaded spring 18 drives the mounting shaft 17 and the clamping component 15 to reset. The spring-loaded spring 18 can not only prevent the clamping component 15 from moving arbitrarily and ensure stable clamping of the workpiece by the clamping component 15, but also enable the multiple clamping components 15 to reset smoothly after the workpiece is removed.

[0035] A sequential drive mechanism is arranged between multiple sliding frames 3 and is movably mounted on the mounting frame 2. The sequential drive mechanism is used to sequentially drive multiple end-face adjustment structures and adjust the position of the workpiece fixing structure. The sequential drive mechanism includes a moving slide 19 and a transmission drive belt 20. The transmission drive belt 20 is driven within the moving slide 19 via a transmission structure, which includes a transmission shaft 23 and a first drive motor 24. Multiple transmission shafts 23 are rotatably connected within the moving slide 19, and transmission wheels are mounted on the transmission shafts 23. The transmission drive belt 20 is driven between the multiple transmission wheels. The first drive motor 24 is mounted on the moving slide 19, and the output end of the first drive motor 24 is connected to... A drive shaft 23 is fixedly connected, and a friction section 21 is provided on the outer arc surface of the drive belt 20. A friction ring sleeve 22 is fixedly sleeved on the rotating shaft 7. When the rotating shaft 7 needs to be driven, the sliding groove 19 is moved to the bottom of the corresponding rotating shaft 7, and the first drive motor 24 is started. The drive belt 20 is driven to circulate in the sliding groove 19 through the drive shaft 23 and the drive wheel, so that the friction section 21 area on the drive belt 20 contacts the friction ring sleeve 22, and the rotating shaft 7 rotates in the sliding groove. The area on the drive belt 20 without the friction section 21 is kept at a sufficient distance from the friction ring sleeve 22, so that the drive belt 20 can move between the bottoms of multiple rotating shafts 7.

[0036] It also includes a movable slide rail 25, a transmission screw 26, and a second drive motor 27. The movable slide rail 25 is fixedly connected to multiple sliding frames 3. The movable slide groove 19 is slidably connected to the movable slide rail 25. The transmission screw 26 is rotatably connected to the movable slide rail 25. The movable slide groove 19 is threadedly connected to the transmission screw 26. The second drive motor 27 is mounted on the movable slide rail 25. The output end of the second drive motor 27 is fixedly connected to the transmission screw 26. When it is necessary to drive the movable slide groove 19 to move laterally, the second drive motor 27 is started to drive the transmission screw 26 to rotate, so that the movable slide groove 19 moves between multiple rotating shafts 7, and moves the transmission drive belt 20 to the bottom of the corresponding rotating shaft 7.

[0037] It also includes a transverse slide rail 28, a connector 29, a rotating screw 30, and a third drive motor 31. Transverse slide rails 28 are provided on both sides of the mounting frame 2. Connectors 29 are fixedly connected between multiple sliding grooves 4. Connectors 29 are slidably connected between two transverse slide rails 28. A rotating screw 30 is rotatably connected to one of the transverse slide rails 28. The rotating screw 30 is threadedly connected to the connector 29. A third drive motor 31 is provided on one of the transverse slide rails 28. The output end of the third drive motor 31 is fixedly connected to the rotating screw 30. When it is necessary to move multiple sliding grooves 4 within multiple sliding frames 3, the third drive motor 31 is started to drive the rotating screw 30 to rotate, so that the connector 29 moves between the two transverse slide rails 28, so that the connector 29 drives multiple sliding grooves 4 to move together, moving the sliding grooves 4 and the clamped workpiece to an area that is convenient for the loading robot arm 1 to operate.

[0038] It also includes a receiving box 32, a rotating seat 33, and a sloped pusher 35. The rotating seat 33 is provided on the inner bottom wall of the sliding frame 3. A support plate 34 is rotatably connected to the rotating seat 33. The receiving box 32 is fixedly connected to one side of the support plate 34, and the sloped pusher 35 is fixedly connected to the other side of the support plate 34. The sloped pusher 35 contacts the sliding groove 4. In order to temporarily place the processed workpiece, when the sliding groove 4 moves towards the workpiece feeding system 36, the sliding groove 4 contacts the sloped pusher 35, pushing the support plate 34 to move along the center point of the rotating seat 33, flipping the receiving box 32 upward along the center point of the rotating seat 33, and moving the receiving box 32 to the upper side of the sliding frame 3, so that the loading robot arm 1 can transfer the processed workpiece into the receiving box 32.

[0039] Working principle of the end-positioning device of this five-axis linkage machining center:

[0040] First, place multiple unprocessed workpieces on the fixed platform 14, and clamp the workpieces with multiple clamping parts 15. Start the third drive motor 31 to drive the rotating screw 30 to rotate, so that the connecting part 29 moves between the two transverse slide rails 28, and the connecting part 29 drives multiple sliding grooves 4 to move together, moving the sliding grooves 4 and the clamped workpieces to an area that is convenient for the loading robot arm 1 to operate.

[0041] Then, when the workpiece feeding system 36 processes the last end face of the workpiece, the tilt angle of the workpiece is determined. The second drive motor 27 is then started to rotate the transmission screw 26, causing the moving slide 19 to move between multiple rotating shafts 7. The transmission drive belt 20 is moved to the bottom of the corresponding rotating shaft 7. The first drive motor 24 is then started, driving the transmission drive belt 20 to circulate within the moving slide 19 via the transmission shaft 23 and transmission wheel. This causes the friction section 21 area on the transmission drive belt 20 to contact the friction ring sleeve 22, causing the rotating shaft 7 to rotate within the sliding groove, thus moving the sliding seat... 6. Move along the inner wall of the arc-shaped slide rail 5 to adjust the position of the sliding seat 6. Then, start the drive electric cylinder 12 to drive the fixed rod 10 and the ball seat 9 to move together in the spherical groove 8, so that the ball seat 9 moves along the inner wall of the arc-shaped groove, making the tilt angle of the workpiece consistent with the tilt angle of the workpiece clamped on the workpiece feed system 36. Then, use two loading robotic arms 1 to cooperate to exchange the unprocessed workpiece and the processed workpiece, so that the five-axis linkage machining center can continue to process the next workpiece without adjusting the workpiece feed system 36 and changing the tool.

[0042] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
