Description
Technical Field
[0001] This invention relates to the field of composite machine tool technology, specifically to a feeding device and method for using a composite machine tool. Background Technology
[0002] Machine tools that use cutting heads such as milling cutters, drills, or grinding heads are called cutting machine tools. With the popularization of laser processing methods, which have advantages such as high precision, high efficiency, and non-contact processing, composite machine tools that combine laser heads and cutting heads have emerged.
[0003] For example, when it is necessary to cut and groove long strips of profiles, a composite machine tool that combines a laser head and a milling cutter head is required. The laser head can cut the long strips of profiles, and the milling cutter head can groove them.
[0004] The composite machine tool consists of a machine body with a worktable mounted on it. A laser head and a cutting head are located above the worktable. Feeding materials onto the worktable requires the assistance of a robotic arm. Since the robotic arm is independent of the machine tool, it still occupies additional factory space when not in use, hindering the movement of workers and forklifts, thus reducing space utilization. Summary of the Invention
[0005] The present invention addresses the aforementioned shortcomings of the existing technology by providing a feeding device and method for using a composite machine tool. The present invention can be hidden inside the housing cavity of the machine body, without occupying factory space, avoiding obstruction of workers and forklifts and other equipment, and improving space utilization.
[0006] To achieve the above objectives, the present invention provides the following technical solution: A feeding device for a composite machine tool includes a machine body with a worktable on the machine body. A laser head and a cutting head are mounted above the worktable, and a receiving cavity is located below the worktable. A movable seat and a moving mechanism are mounted on the inner top wall of the receiving cavity. The moving mechanism is used to drive the movable seat to move laterally and longitudinally. A rotary arm and a first rotary mechanism are mounted on the movable seat. The first rotary mechanism is used to drive the rotary arm to rotate. A telescopic arm and a second rotary mechanism are mounted on the rotary arm. The second rotary mechanism is used to drive the telescopic arm to rotate around the rotary arm. A clamp and an angle adjustment mechanism are mounted at the end of the telescopic arm away from the rotary arm. The angle adjustment mechanism is used to adjust the angle of the clamp.
[0007] Furthermore, the interior of the machine body is provided with a partition plate, a working cavity is provided above the partition plate, a worktable is provided at the top of the working cavity, and a receiving cavity is provided below the partition plate.
[0008] Furthermore, the movable seat includes a transverse sliding seat and a longitudinal sliding seat. The transverse sliding seat is slidably connected to the inner top wall of the receiving cavity in the transverse direction, and the longitudinal sliding seat is slidably connected to the transverse sliding seat in the longitudinal direction. The longitudinal sliding seat is provided with the rotary arm and the first rotary mechanism. The moving mechanism includes a transverse component and a longitudinal component. The transverse component is used to drive the transverse seat to move laterally, and the longitudinal component is used to drive the longitudinal seat to move longitudinally.
[0009] Furthermore, a rotating shaft is fixedly provided on the side wall of the rotary arm, and the rotating shaft is rotatably connected to the longitudinal sliding seat. The first rotary mechanism drives the rotary arm to rotate through the rotating shaft.
[0010] Furthermore, the movable seat is provided with a guide groove on the side facing the rotary arm. The guide groove includes a connected arc segment and a variable diameter segment. The center of the arc segment is located on the rotating shaft. The end of the variable diameter segment that is connected to the arc segment is designated as the first end, and the end of the variable diameter segment that is away from the arc segment is designated as the second end. The distance between the second end and the rotating shaft is greater than the distance between the first end and the rotating shaft. The second rotary mechanism includes a slide plate, a guide pin, a ring, and a sliding pin. The slide plate slides along the axial direction of the rotary arm and is slidably engaged with the axial groove. The outer side wall of the slide plate is provided with a guide pin, which slides with the guide groove. The outer side wall of the slide plate is also provided with a spiral groove with a rotation angle of 180°. The ring is sleeved on the outer side of the rotary arm and the slide plate and rotates around the circumference of the rotary arm. The inner side wall of the ring is provided with a sliding pin, which slides with the spiral groove. The outer side wall of the ring is provided with the telescopic arm.
[0011] Furthermore, the clamp includes a base plate, a fixed clamping plate, a movable clamping plate, and a clamp telescopic rod. The middle part of the base plate is rotatably connected to the end of the telescopic arm away from the rotary arm. The base plate is provided with a fixed clamping plate, a movable clamping plate, and a clamp telescopic rod. The clamp telescopic rod is used to drive the movable clamping plate to move closer to or away from the fixed clamping plate longitudinally. The angle adjustment mechanism includes an angle telescopic rod, one end of which is rotatably connected to the telescopic arm, and the other end of which is rotatably connected to the longitudinal end of the base plate.
[0012] A method of using a feeding device for a composite machine tool, based on the aforementioned feeding device for a composite machine tool, includes the following steps when conveying a long strip of profile onto the worktable: (1) Park the flatbed cart loaded with profiles on the ground in front of the machine body; (2) The first rotary mechanism drives the rotary arm to rotate to a horizontal position outside the receiving cavity, so that the clamp moves out of the receiving cavity; (3) The moving mechanism drives the moving seat to move longitudinally, so that the clamp moves above the profile; (4) The extension of the telescopic arm causes the clamp to move downward; (5) The clamp holds the profile; (6) The first rotary mechanism drives the rotary arm to rotate from a horizontal state to a vertical state, and the second rotary mechanism drives the telescopic arm to rotate 180° around the rotary arm, so that the profile flips 180° upward and reaches the top of the worktable; (7) The angle adjustment mechanism changes the angle between the clamp and the telescopic arm from 90° to 180°, so that the profile held by the clamp faces the worktable. (8) The moving mechanism drives the moving seat to move laterally and longitudinally, so that the profile moves laterally and longitudinally to the target lateral position and the target longitudinal position; (9) The clamp releases the profile so that the profile is placed on the worktable.
[0013] Furthermore, in step (5), the clamp holds the end of the profile, so that the other end of the profile is suspended in the air; In step (6), when the second rotary mechanism drives the telescopic arm to rotate 180° around the rotary arm, the suspended end of the profile flips upward 180° and reaches above the workbench.
[0014] Furthermore, between step (1) and step (2), the moving mechanism drives the moving seat to move laterally to the end of the machine body, and the moving seat drives the clamp to move to the end of the machine body.
[0015] Furthermore, in step (8), the profile is moved longitudinally to the target longitudinal position by extending and retracting the telescopic arm.
[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In the feeding device, the receiving cavity on the machine body provides storage space to accommodate the moving seat, moving mechanism, rotary arm, first rotary mechanism, telescopic arm, second rotary mechanism, clamp, and angle adjustment mechanism. During profile feeding operations, these structures extend from the receiving cavity; when not feeding, they are concealed within the receiving cavity, thus not occupying factory space, avoiding obstruction of workers and forklift movement, and improving space utilization.
[0017] 2. Because the receiving cavity can accommodate the moving seat, moving mechanism, rotating arm, first rotating mechanism, telescopic arm, second rotating mechanism, clamp and angle adjustment mechanism, the entire feeding device has a compact structure, which can save transportation and storage space and facilitate transportation and storage.
[0018] 3. The moving mechanism can adjust the lateral and longitudinal positions of the moving base. The moving base can drive the rotary arm, telescopic arm, and clamp to move together, allowing the clamp to pick up profiles at different lateral and longitudinal positions. The length of the telescopic arm can be changed, allowing the height of the clamp on the telescopic arm to be changed, enabling the clamp to pick up profiles at different heights. Both the moving mechanism and the telescopic arm expand the clamping range of the clamp and improve the flexibility of feeding materials onto the worktable. Furthermore, when placing profiles, the moving mechanism and the telescopic arm can adjust the placement position of the profiles on the worktable, improving the accuracy of feeding.
[0019] 4. The first slewing mechanism drives the slewing arm to rotate, and the second slewing mechanism drives the telescopic arm to rotate around the slewing arm. When the slewing arm, telescopic arm, and clamp are all located within the receiving cavity, the slewing arm rotates to a vertically downward position, the telescopic arm is in a horizontal position, and the clamp is located at the end of the telescopic arm furthest from the slewing arm. This allows the clamp to be located deep within the receiving cavity, reducing the risk of workers kicking or hitting the clamp, improving the protection of the clamp, and reducing potential losses.
[0020] 5. The second rotary mechanism achieves the rotation of the telescopic arm around the rotary arm without using a power source, which helps save energy and reduce costs. For example, when the rotary arm rotates from a horizontal position to a vertically upward position, the telescopic arm can rotate 180° around the rotary arm from a vertically downward position to a horizontal position above the worktable by utilizing the cooperation of the slide plate, guide pin, guide groove, sliding pin, spiral groove and ring in the second rotary mechanism.
[0021] 6. The second slewing mechanism can also improve the attitude adjustment efficiency of the telescopic boom. As the slewing boom changes state, the telescopic boom also changes state accordingly, which helps improve adjustment efficiency.
[0022] 7. The second slewing mechanism is a simple mechanical structure, which can reduce the load on the slewing arm, thereby reducing the load on the first slewing mechanism when driving the slewing arm to rotate, which is conducive to improving the stability of the first slewing mechanism when driving the slewing arm to rotate.
[0023] 8. Angle Adjustment Mechanism: By adjusting the angle of the clamp, the clamp can easily pick up and release profiles, improving the accuracy of clamping and releasing profiles. When the angle between the clamp and the telescopic arm is 90°, the clamp can pick up the profiles on the trolley from the front; when the angle between the clamp and the telescopic arm is 180°, the clamp can release the profiles from the front onto the worktable.
[0024] 9. When the rotary arm rotates from a horizontal position to a vertically upward position, the telescopic arm rotates 180° upwards around the rotary arm from a vertically downward position to a horizontal position above the worktable. The telescopic arm drives the clamp to rotate together, and the clamp drives the profile to rotate together. If the clamp directly grips the middle of the long profile, the lower part of the profile is easily obstructed by the ground or the trolley during the rotation process, hindering the smooth rotation of the profile. Therefore, in the method of use of this invention, by having the clamp grip the end of the profile, the suspended end of the profile can be rotated upwards by 180°, which can make full use of the space above the rotary arm and allow the long profile to rotate smoothly. This improves the reliability of conveying long profiles.
[0025] 10. Before using the clamp to pick up the profile, move the moving seat to move the clamp to the end of the machine body and use the clamp to pick up the end of the profile. When flipping the profile 180°, the entire profile can be flipped directly to the top of the worktable, reducing the range of subsequent adjustment of the profile's lateral and longitudinal position using the moving mechanism and improving the efficiency of conveying the profile to the worktable.

Detailed Implementation
[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0029] Example 1: A feeding device for a composite machine tool, see [link / reference] Figure 3 The device includes a fuselage 1, and a partition plate 11 is fixedly installed inside the fuselage 1. A working cavity 12 is provided above the partition plate 11, and a receiving cavity 13 is provided below the partition plate 11.
[0030] See Figure 3 A worktable 2 is installed on the top of the working chamber 12.
[0031] See Figure 1 and Figure 2 Several positioning bases 21 are installed on the worktable 2. The positioning bases 21 are slidably connected to the worktable 2 in the transverse direction. A positioning motor 22, which can be a servo motor, is fixedly installed on the positioning base 21. A positioning gear 23 is fixedly installed at the output end of the positioning motor 22. A positioning rack 24 is fixedly installed on the side of the worktable 2. The positioning rack 24 extends in the transverse direction, and the positioning gear 23 meshes with the positioning rack 24. After the positioning motor 22 is started, the positioning motor 22 drives the positioning gear 23 to rotate, and the positioning gear 23 drives the positioning base 21 to move laterally along the positioning rack 24.
[0032] See Figure 2 A positioning plate 25 and a positioning telescopic rod 27 are fixedly installed on the positioning base 21. The positioning telescopic rod 27 can be a hydraulic cylinder, a pneumatic cylinder, or an electric push rod. The piston rod of the positioning telescopic rod 27 extends and retracts longitudinally, and a positioning wheel 26 is fixedly installed on the piston rod of the positioning telescopic rod 27. The extension and retraction of the positioning telescopic rod 27 can drive the positioning wheel 26 to approach or move away from the positioning plate 25 longitudinally. When the positioning wheel 26 approaches the positioning plate 25, the positioning wheel 26 and the positioning plate 25 can clamp the elongated profile 40; when the positioning wheel 26 moves away from the positioning plate 25, the positioning wheel 26 and the positioning plate 25 can release the elongated profile 40.
[0033] Because the lateral position of the positioning base 21 is adjustable under the action of the positioning motor 22, the positioning gear 23 and the positioning rack 24, the clamping position of the positioning plate 25 and the positioning wheel 26 on the profile 40 is adjustable, which helps to improve the flexibility of clamping the profile 40.
[0034] See Figure 1 A laser head 3 and a cutting head 4 are located above the worktable 2. The laser head 3 uses laser cutting to cut the profile 40. The cutting head 4 can be at least one of a milling cutter, a drill bit, and a grinding head. The milling cutter is used to machine grooves in the profile 40, the drill bit is used to drill holes in the profile 40, and the grinding head is used to grind the profile 40. During the machining of the profile 40, the waste chips generated are collected in the working cavity 12. See also Figure 1 and Figure 3The working chamber 12 has a waste discharge port 14 on its side wall. When it is necessary to clean up the waste, the worker can use a broom to sweep the waste in the working chamber 12 out through the waste discharge port 14.
[0035] See Figure 4 The inner top wall of the receiving cavity 13 is provided with a movable seat and a moving mechanism. The inner top wall of the receiving cavity 13 is the bottom surface of the partition plate 11. The moving mechanism is used to drive the movable seat to move laterally and longitudinally. See also... Figure 7 The movable seat includes a transverse movable seat 51 and a longitudinal movable seat 52. The transverse movable seat 51 is slidably connected to the inner top wall of the receiving cavity 13 in the transverse direction, and the longitudinal movable seat 52 is slidably connected to the transverse movable seat 51 in the longitudinal direction. The moving mechanism includes a transverse movable component and a longitudinal movable component. The transverse movable component is used to drive the transverse movable seat 51 to move in the transverse direction, and the longitudinal movable component is used to drive the longitudinal movable seat 52 to move in the longitudinal direction.
[0036] This embodiment 1 provides a specific structure for the lateral movement component: see [link / reference] Figure 7 The lateral movement assembly includes a lateral movement motor 611, a lateral movement gear 612, and a lateral movement rack 613. The lateral movement motor 611 is a servo motor and is fixedly mounted on the lateral movement base 51. The lateral movement gear 612 is fixedly mounted on the output end of the lateral movement motor 611. The lateral movement gear 612 meshes with the lateral movement rack 613, which is fixedly mounted on the inner top wall of the receiving cavity 13 and extends laterally. When the lateral movement motor 611 drives the lateral movement gear 612 to rotate forward, the lateral movement gear 612 drives the lateral movement base 51 to move from left to right along the lateral movement rack 613. When the lateral movement motor 611 drives the lateral movement gear 612 to rotate in reverse, the lateral movement gear 612 drives the lateral movement base 51 to move from right to left along the lateral movement rack 613.
[0037] In addition to the gear and rack structure mentioned above, the transverse movement assembly can also use a screw and nut structure, a cylinder, a hydraulic cylinder, or an electric cylinder to drive the transverse movement seat 51 to move laterally.
[0038] This embodiment 1 provides a specific structure for the longitudinal translation component: see [link / reference] Figure 7 and Figure 8 The longitudinal movement assembly employs a rodless cylinder 62. The rodless cylinder 62 refers to a cylinder that uses a piston 621 to directly or indirectly connect to an external actuator, causing it to reciprocate along with the piston 621. In this embodiment 1, the rodless cylinder 62 is fixedly mounted on the transverse moving seat 51, and the piston 621 of the rodless cylinder 62 is fixedly mounted together with the longitudinal moving seat 52, allowing the longitudinal moving seat 52 to move longitudinally along with the piston 621 of the rodless cylinder 62.
[0039] Using rodless cylinder 62 can save installation space. In addition to using rodless cylinder 62, the longitudinal movement assembly can also use a gear and rack structure, a lead screw and nut structure, a hydraulic cylinder or an electric cylinder to drive the longitudinal movement seat 52 to move longitudinally.
[0040] See Figure 6 The longitudinal sliding seat 52 is equipped with a rotary arm 7 and a first rotary mechanism. A rotating shaft 71 is fixedly installed on the side wall of the rotary arm 7, and the rotating shaft 71 is rotatably connected to the longitudinal sliding seat 52 through a bearing. The first rotary mechanism drives the rotary arm 7 to rotate through the rotating shaft 71.
[0041] This embodiment 1 provides a specific structure for the first rotary mechanism: see [link / reference] Figure 5 and Figure 6 The first rotary mechanism includes a rotary motor 8, which may be a servo motor. The rotary motor 8 is fixedly mounted on the longitudinal sliding seat 52, and the output shaft of the rotary motor 8 is fixedly connected to the rotating shaft 71. When the rotary motor 8 starts, the output shaft of the rotary motor 8 drives the rotating shaft 71 to rotate together, and the rotating shaft 71 drives the rotary arm 7 to rotate together.
[0042] The slewing arm 7 is equipped with a telescopic arm 9 and a second slewing mechanism. (See also...) Figure 6 The telescopic boom 9 can be a hydraulic cylinder, a pneumatic cylinder, or an electric cylinder. The second slewing mechanism is used to drive the telescopic boom 9 to rotate around the slewing boom 7.
[0043] See Figure 10 In this embodiment 1, the second rotating mechanism includes a sliding plate 101, a guide pin 102, a ring 103, and a sliding pin 104.
[0044] See Figure 10 The side wall of the rotary arm 7 is provided with an axial groove 72. The slide plate 101 slides in the axial groove 72 along the axial direction of the rotary arm 7. Furthermore, the outer side wall of the slide plate 101 and the outer side wall of the rotary arm 7 are joined together to form a cylindrical surface so that the ring 103 can be fitted on the outer side of the slide plate 101 and the rotary arm 7.
[0045] See Figure 10 A guide pin 102 is fixedly installed on the outer wall of the slide plate 101. The guide pin 102 slides in conjunction with the guide groove. (See attached image) Figure 8 The guide groove is located on the side of the longitudinal sliding seat 52 facing the rotary arm 7. The guide groove includes a connected arc segment 521 and a variable diameter segment 522. The center of the arc segment 521 is located on the rotating shaft 71. The end of the variable diameter segment 522 that is connected to the arc segment 521 is designated as the first end, and the end of the variable diameter segment 522 that is away from the arc segment 521 is designated as the second end. The distance between the second end and the rotating shaft 71 is greater than the distance between the first end and the rotating shaft 71.
[0046] See Figure 6 The ring 103 is sleeved on the outside of the rotary arm 7 and the slide plate 101, and the ring 103 rotates and cooperates with the rotary arm 7 around the circumference of the rotary arm 7.
[0047] See Figure 8 and Figure 10To prevent the ring 103 from moving axially, two limit blocks 73 are fixedly installed on the rotary arm 7. The ring 103 is sandwiched between the two limit blocks 73, and the two limit blocks 73 prevent the ring 103 from moving axially.
[0048] See Figure 10 The outer wall of the slide plate 101 is also provided with a spiral groove 1011, the spiral groove 1011 having a rotation angle of 180°. A sliding pin 104 is fixedly installed on the inner wall of the ring 103, and the sliding pin 104 slides in engagement with the spiral groove 1011. See Figure 8 A telescopic arm 9 is fixedly installed on the outer wall of the ring 103.
[0049] The working principle of the second rotary mechanism is as follows: See Figure 9 When the rotary arm 7 is in a vertically downward position, the guide pin 102 on the slide plate 101 is located within the arc segment 521, and the telescopic arm 9 is horizontally located within the receiving cavity 13.
[0050] When the first rotary mechanism drives the rotary arm 7 to rotate counterclockwise around the rotation center of the shaft 71, the rotary arm 7 rotates outward from the receiving cavity 13. During the process of the rotary arm 7 rotating to a horizontal state, the guide pin 102 slides within the arc segment 521. Because the radius of the arc segment 521 is the same at all points, the slide plate 101, which is fixedly connected to the guide pin 102, will not move axially on the rotary arm 7. Because the slide plate 101 does not move axially, the spiral groove 1011 on the slide plate 101 does not move axially, and the sliding pin 104 located inside the spiral groove 1011 is not axially pushed by the spiral groove 1011, thus keeping the sliding pin 104 stationary. The ring 103, which is fixedly connected to the sliding pin 104, remains stationary relative to the rotary arm 7; that is, the ring 103 does not rotate circumferentially around the rotary arm 7, and the telescopic arm 9, which is fixedly connected to the ring 103, also does not rotate circumferentially around the rotary arm 7. See also Figure 8 When the slewing arm 7 rotates to a horizontal position, the telescopic arm 9 is in a vertically downward position.
[0051] When the first rotary mechanism drives the rotary arm 7 to continue rotating counterclockwise, causing the rotary arm 7 to rotate from a horizontal state to a vertically upward state, the guide pin 102 slides within the variable diameter section 522. Since the end of the variable diameter section 522 connected to the arc section 521 is designated as the first end, and the end of the variable diameter section 522 away from the arc section 521 is designated as the second end, and the distance between the second end and the rotating shaft 71 is greater than the distance between the first end and the rotating shaft 71, the distance between the guide pin 102 and the rotating shaft 71 increases. The slide plate 101, fixedly connected to the guide pin 102, moves axially on the rotary arm 7. Because the slide plate 101 moves axially, the spiral groove 1011 on the slide plate 101 applies an axial thrust to the sliding pin 104. Since the spiral angle of the spiral groove 1011 is 180°, the ring 103 fixedly connected to the sliding pin 104 cannot move axially. Therefore, the sliding pin 104 drives the ring 103 to rotate 180° circumferentially around the rotary arm 7. (See also...) Figure 14 When the rotary arm 7 is in a vertically upward position, the ring 103 rotates 180° around the rotary arm 7, and the telescopic arm 9, which is fixedly connected to the ring 103, also rotates 180° around the rotary arm 7, so that the telescopic arm 9 is horizontally above the worktable 2.
[0052] When the first rotary mechanism drives the rotary arm 7 to rotate clockwise, causing the rotary arm 7 to rotate from a vertically upward state to a horizontal state, the guide pin 102 on the slide plate 101 slides in the reverse direction within the variable diameter section 522, reducing the distance between the guide pin 102 and the rotating shaft 71. The slide plate 101, which is fixedly connected to the guide pin 102, moves axially in the reverse direction on the rotary arm 7 to reset. When the slide plate 101 moves axially in the reverse direction to reset, the spiral groove 1011 on the slide plate 101 applies a reverse axial thrust to the sliding pin 104, causing the sliding pin 104 to drive the ring 103 to rotate circumferentially in the reverse direction around the rotary arm 7. When the rotary arm 7 resets to a horizontal state, the ring 103 drives the telescopic arm 9 to rotate 180° in the reverse direction, causing the telescopic arm 9 to reset to a vertically downward state, i.e., to restore... Figure 8 The state shown.
[0053] When the first rotary mechanism continues to drive the rotary arm 7 to rotate clockwise, causing the rotary arm 7 to rotate from a horizontal state to a vertically downward state, the guide pin 102 slides within the arc segment 521. Because the radius is the same at all points within the arc segment 521, the slide plate 101 will not move axially on the rotary arm 7. Because the slide plate 101 does not move axially, the spiral groove 1011 on the slide plate 101 does not move axially, and the sliding pin 104 that cooperates with the spiral groove 1011 is not pushed axially by the spiral groove 1011. This causes the ring 103 sleeved on the outside of the slide plate 101 to not rotate circumferentially around the rotary arm 7, and the telescopic arm 9 fixedly connected to the ring 103 to not rotate circumferentially around the rotary arm 7. When the rotary arm 7 returns to the vertically downward state, the telescopic arm 9 returns to the horizontal state within the receiving cavity 13.
[0054] Based on the above-described working principle of the second rotary mechanism, it can be seen that the second rotary mechanism provided in Embodiment 1 has the following advantages: First, the second rotary mechanism achieves the rotation of the telescopic arm 9 around the rotary arm 7 without using a power source, which helps save energy and reduce costs. For example, when the rotary arm 7 rotates from a horizontal position to a vertically upward position, the telescopic arm 9 can rotate 180° around the rotary arm 7 from a vertically downward position to a horizontal position above the worktable 2 by utilizing the cooperation of the slide plate 101, guide pin 102, guide groove, slide pin 104, spiral groove 1011 and ring 103 in the second rotary mechanism.
[0055] Secondly, the second slewing mechanism can also improve the attitude adjustment efficiency of the telescopic arm 9. While the slewing arm 7 changes state, the telescopic arm 9 also changes state accordingly, which helps to improve the adjustment efficiency.
[0056] Third, the second slewing mechanism is a simple mechanical structure, which can reduce the load on the slewing arm 7, thereby reducing the load when the first slewing mechanism drives the slewing arm 7 to rotate, which is conducive to improving the stability when the first slewing mechanism drives the slewing arm 7 to rotate.
[0057] The telescopic arm 9 is equipped with a clamp and an angle adjustment mechanism at the end away from the rotary arm 7. The clamp is used to hold the profile 40, and the angle adjustment mechanism is used to adjust the angle of the clamp.
[0058] This embodiment 1 provides a specific structure for the clamp and angle adjustment mechanism: See Figure 8 The clamp includes a base plate 201, a fixed clamping plate 202, a movable clamping plate 203, and a clamp telescopic rod 204. The middle of the base plate 201 is rotatably connected to the end of the telescopic arm 9 away from the rotating arm 7. The fixed clamping plate 202 and the clamp telescopic rod 204 are fixedly mounted on the base plate 201. The clamp telescopic rod 204 is a hydraulic cylinder, pneumatic cylinder, or electric cylinder. The movable clamping plate 203 is fixedly mounted on the piston rod of the clamp telescopic rod 204. The clamp telescopic rod 204 drives the movable clamping plate 203 to move longitudinally closer to or away from the fixed clamping plate 202. When the movable clamping plate 203 approaches the fixed clamping plate 202, it can clamp the profile 40; when the movable clamping plate 203 moves away from the fixed clamping plate 202, it can release the profile 40.
[0059] See Figure 8 The angle adjustment mechanism includes an angle telescopic rod 30, which can be a hydraulic cylinder, pneumatic cylinder, or electric cylinder. One end of the angle telescopic rod 30 is rotatably connected to the telescopic arm 9, and the other end is rotatably connected to one longitudinal end of the base plate 201. The angle of the clamp can be adjusted by extending and retracting the angle telescopic rod 30. For example, in… Figure 8 In the fixture, the angle between the base plate 201 and the telescopic arm 9 is 90°.
[0060] Example 2: A method of using a feeding device for a composite machine tool, based on the feeding device for a composite machine tool of Embodiment 1. When feeding a long strip of profile 40 onto the worktable 2, the method includes the following steps: (1) Park the flatbed cart 50 containing the profile 40 on the ground in front of the machine body 1.
[0061] (2) The transverse component in the moving mechanism drives the transverse seat 51 to move laterally to the end of the machine body 1. The transverse seat 51 drives the longitudinal seat 52, the rotary arm 7, the telescopic arm 9 and the clamp to move laterally to the end of the machine body 1 together.
[0062] (3) See Figures 9 to 8 As the state changes, the first rotary mechanism drives the rotary arm 7 to rotate to a horizontal state outside the receiving cavity 13. The rotary arm 7 drives the telescopic arm 9 to move, so that the telescopic arm 9 changes from a horizontal state inside the receiving cavity 13 to a vertical downward state outside the receiving cavity 13. The telescopic arm 9 drives the clamp to move, so that the clamp moves out of the receiving cavity 13.
[0063] (4) The longitudinal component in the moving mechanism drives the longitudinal shifting seat 52 to move longitudinally. The longitudinal shifting seat 52 drives the rotary arm 7, the telescopic arm 9, and the clamp to move longitudinally together, so that the clamp moves longitudinally above the profile 40, so as to clamp the profile 40.
[0064] (5) The extension of the telescopic arm 9 causes the clamp to move down and approach the profile 40, so that the clamp can clamp profiles 40 of different heights.
[0065] (6) The clamp holds one end of the profile 40, and the other end of the profile 40 is suspended in the air. The state of the feeding device at this time can be seen from [reference needed]. Figure 11 and Figure 12 .
[0066] (7) The first rotary mechanism drives the rotary arm 7 to rotate from a horizontal state to a vertical state. Under the action of the second rotary mechanism, the telescopic arm 9 rotates 180° around the rotary arm 7, so that the telescopic arm 9 rotates from a vertical downward state to a horizontal state above the worktable 2, causing the suspended end of the profile 40 to flip upward 180° and reach above the worktable 2. At this time, the state of the feeding device can be seen in [reference needed]. Figure 13 and Figure 14 .
[0067] (8) The angle telescopic rod 30 extends, and the angle between the clamp and the telescopic arm 9 changes from 90° to 180°, so that the profile 40 held by the clamp can face the worktable 2. At this time, the state of the feeding device can be seen in [reference needed]. Figure 15 and Figure 16 .
[0068] (9) The transverse component in the moving mechanism drives the transverse seat 51 to move laterally. The transverse seat 51 drives the longitudinal seat 52, the rotary arm 7, the telescopic arm 9 and the clamp to move laterally together. The clamp drives the profile 40 to move laterally together, so that the profile 40 moves laterally to the target transverse position.
[0069] The longitudinal moving component in the moving mechanism drives the longitudinal moving seat 52 to move longitudinally. The longitudinal moving seat 52 drives the rotary arm 7, the telescopic arm 9, and the clamp to move longitudinally together. The clamp drives the profile 40 to move longitudinally together, so that the profile 40 moves longitudinally to the target longitudinal position. When the longitudinal moving component cannot drive the profile 40 to the target longitudinal position, the extension and retraction of the telescopic arm 9 can be used to drive the profile 40 to move longitudinally until the profile 40 moves to the target longitudinal position.
[0070] (10) The clamp releases the profile 40, allowing the front of the profile 40 to fall onto the worktable 2. After the profile 40 falls onto the worktable 2, the positioning telescopic rod 27 on the worktable 2 drives the positioning wheel 26 to approach the positioning plate 25, so that the profile 40 is clamped by the positioning plate 25 and the positioning wheel 26, thereby improving the stability of the profile 40 when it is subsequently processed by the laser head 3 or the cutting head 4.
[0071] Through the above-described method of use in this embodiment 2, it can be seen that the feeding device has the following advantages: First, in the feeding device, the receiving cavity 13 on the machine body 1 provides a receiving space for accommodating the moving seat, the moving mechanism, the rotating arm 7, the first rotating mechanism, the telescopic arm 9, the second rotating mechanism, the clamp, and the angle adjustment mechanism. When feeding the profile 40, the above structures extend from the receiving cavity 13; when not feeding, see [reference needed]. Figure 9 The aforementioned structure is hidden within the containment cavity 13, thus not occupying factory space, avoiding obstruction of workers and equipment such as forklifts, and improving space utilization.
[0072] Secondly, because the receiving cavity 13 can accommodate the movable seat, the moving mechanism, the rotating arm 7, the first rotating mechanism, the telescopic arm 9, the second rotating mechanism, the clamp, and the angle adjustment mechanism, the entire feeding device has a compact structure, which can save transportation and storage space and facilitate transportation and storage.
[0073] Third, the moving mechanism can adjust the lateral and longitudinal positions of the moving seat. The moving seat can drive the rotary arm 7, the telescopic arm 9, and the clamp to move together, allowing the clamp to grip profiles 40 at different lateral and longitudinal positions. The length of the telescopic arm 9 can be changed, allowing the height of the clamp on the telescopic arm 9 to be changed, enabling the clamp to grip profiles 40 at different heights. Both the moving mechanism and the telescopic arm 9 expand the range of the clamp gripping profiles 40, improving the flexibility of feeding materials onto the worktable 2. Furthermore, when placing profiles 40, the moving mechanism and the telescopic arm 9 can adjust the placement position of the profiles 40 on the worktable 2, improving the accuracy of feeding.
[0074] Fourth, the first rotating mechanism can drive the rotating arm 7 to rotate, and the second rotating mechanism can drive the telescopic arm 9 to rotate around the rotating arm 7. When the rotating arm 7, the telescopic arm 9, and the clamp are all located within the receiving cavity 13, the rotating arm 7 rotates to a vertically downward position, the telescopic arm 9 is in a horizontal position, and the clamp is located at the end of the telescopic arm 9 away from the rotating arm 7. This allows the clamp to be located deep within the receiving cavity 13, reducing the risk of workers kicking or hitting the clamp, improving the protection of the clamp, and reducing losses.
[0075] Fifth, the angle adjustment mechanism can facilitate the clamping and releasing of the profile 40 by adjusting the angle of the clamp, thereby improving the accuracy of clamping and releasing the profile 40. When the angle between the clamp and the telescopic arm 9 is 90°, the clamp can clamp the profile 40 on the trolley 50 from the front; when the angle between the clamp and the telescopic arm 9 is 180°, the clamp can release the profile 40 onto the worktable 2 from the front.
[0076] Through the above-described method of use in this embodiment 2, it can also be seen that the method of use has the following advantages: First, when the rotary arm 7 rotates from a horizontal state to a vertically upward state, the telescopic arm 9 rotates 180° upward around the rotary arm 7 from a vertically downward state to a horizontal state above the worktable 2. The telescopic arm 9 drives the clamp to rotate together, and the clamp drives the profile 40 to rotate together.
[0077] If the clamp directly grips the middle of the long strip profile 40, the lower part of the profile 40 is easily blocked by the ground or the flatbed 50 during the flipping process, which will hinder the smooth flipping of the profile 40.
[0078] Therefore, in the usage method of this embodiment 2, by having the clamp grasp the end of the profile 40, the suspended end of the profile 40 can be rotated upwards by 180°, which can make full use of the space above the rotating arm 7 and allow the long strip profile 40 to be rotated smoothly. This improves the reliability of conveying the long strip profile 40.
[0079] Second, see Figures 11 to 13Before using the clamp to pick up the profile 40, the moving seat drives the clamp to the end of the machine body 1, and the clamp picks up the end of the profile 40. When the profile 40 is rotated 180°, the entire profile 40 can be directly rotated to the top of the worktable 2, reducing the range of subsequent adjustment of the profile 40's lateral and longitudinal positions using the moving mechanism, and improving the efficiency of conveying the profile 40 onto the worktable 2.
[0080] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
