Description

Technical Field

[0001] This invention relates to a vertical milling machine, specifically a vertical milling machine for aluminum profile hot extrusion die sleeves and its control method. Background Technology

[0002] As a key component in the hot extrusion forming process, the manufacturing precision of the aluminum profile hot extrusion die sleeve directly affects the forming quality of the aluminum profile and the service life of the die. Milling is a crucial step in the machining of the sleeve, used to form specific geometric features on the outer diameter or end face of the sleeve. Currently, the industry mostly uses traditional vertical milling machines in conjunction with robotic arms for loading and unloading these types of blanks.

[0003] A typical robotic arm consists of a gripper and a conveyor. In use, the gripper holds the blank and then the conveyor transports it. The gripper is equipped with a gripping mold. Selecting the appropriate mold according to the processing requirements can effectively improve the processing accuracy. After processing, the conveyor delivers the semi-finished or finished product and releases it in the correct position.

[0004] Typically, the gripping and conveying components of a robotic arm are controlled by independent drive units, and multiple units are controlled by an electrical automation control system. If a program error or sensor signal interference occurs, the robotic arm may start to move the workpiece before it is reliably clamped, or may accidentally release the workpiece at the processing position, causing equipment collisions or even workpiece flying out, posing a threat to the equipment and operators.

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 embodiments of the present invention, and not all embodiments. 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] Furthermore, elements in this invention are referred to as being "fixed to" or "set on" another element, which may be directly on the other element or may also include an intervening element. When an element is considered to be "connected" to another element, it may be directly connected to the other element or may also include an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations.

[0030] Please see Figures 1-10 As an embodiment of the present invention, the vertical milling equipment for the hot extrusion die sleeve of the aluminum profile includes a support frame 1, a milling module 2 is slidably mounted on the top of the support frame 1, and a processing table 3 is mounted on its bottom; It also includes a swing arm 5, which is rotatably connected to the support frame 1; a symmetrically arranged clamping arm 6 is rotatably mounted on the end of the swing arm 5; a clamping mold 7 is mounted on the clamping arm 6; The clamping member can drive multiple sets of clamping arms 6 to move closer or further apart, so as to clamp or release the blank through the clamping mold 7; A conveyor is used to drive the swing arm 5 to rotate, so as to move the blank closer to or away from the processing table 3 through the clamping member.

[0031] In this embodiment, a suitable clamping mold 7 is selected according to the size of the blank to be processed.

[0032] In the initial state, the swing arm 5 is away from the processing table 3 and aligned with the loading station; in this position, the clamping arms 6 are far apart from each other, so the clamping mold 7 is in a state of being far apart from each other.

[0033] After the blank is conveyed to the middle position of the clamping mold 7, the clamping parts are driven to move. During this process, the clamping arm 6 will drive the clamping mold 7 to move closer to each other to clamp the blank.

[0034] Then the drive conveyor moves, at which point the swing arm 5 rotates toward the processing table 3, thereby using the clamping component to move the blank toward the processing table 3; after the blank reaches the processing position, the milling module 2 will mill the blank (during the processing, the clamping component will maintain the clamping state of the blank).

[0035] After the blank is processed, the control system will control the conveyor to reverse the movement to drive the swing arm 5 to rotate, so as to drive the blank away from the processing table 3 through the clamping component; and when the swing arm 5 rotates to the initial position, it drives the clamping component to reverse the movement, so as to drive the clamping mold 7 away from each other through the clamping arm 6, so as to release the blank.

[0036] The sequence of operations of the equipment is rigidly defined by the mechanical structure, forming a reliable mechanical interlock. It forces the system to "clamp the billet first, then convey it," and after processing, it must "return to a safe position first, then release the billet." This avoids dangerous situations such as "conveying without clamping" or "releasing at the processing position" that may occur due to program errors or signal interference, ensuring the safety of the equipment and operators, and making the operation extremely reliable.

[0037] As a further embodiment of the present invention, the clamping member includes a first gear 601 mounted on the clamping arm 6; a rack plate 17 that meshes with the first gear 601 is slidably mounted on the swing arm 5.

[0038] In this embodiment, the rack plate 17 is located between the two sets of first gears 601.

[0039] Clamping: The rack plate 17 slides on the swing arm 5 and moves away from the clamping arm 6. Through the meshing action of the rack plate 17 and the first gear 601, the first gear 601 can be driven to rotate. The two first gears 601 rotate in opposite directions, so the clamping arms 6 can rotate and move closer to each other, so as to drive the clamping mold 7 to move closer to each other to clamp the blank.

[0040] Release: The rack plate 17 slides on the swing arm 5 and approaches the clamping arm 6. Through the meshing action of the rack plate 17 and the first gear 601, the first gear 601 can be driven to rotate. Since the two first gears 601 rotate in opposite directions, the clamping arms 6 can rotate away from each other, thereby driving the clamping mold 7 away from each other to release the blank.

[0041] The linear motion of the rack plate 17 can drive the two clamping arms 6 to move in opposite directions or in a completely symmetrical and synchronous manner, ensuring that the blank is always clamped in the center position of the clamping mold 7. This effectively avoids the positioning error or uneven force on the blank caused by misalignment of the clamping, laying a solid foundation for subsequent high-precision milling.

[0042] As a further embodiment of the present invention, the conveying component includes a motor 10 mounted on the support frame 1, a second gear 11 mounted on the output end of the motor 10, a third gear 12 rotatably mounted on the support frame 1 and meshing with the second gear 11, a rotating shaft 8 slidably engaged with the third gear 12 on the support frame 1, a rotating sleeve 4 rotatably mounted on the support frame 1 and sleeved with the rotating shaft 8, the rotating sleeve 4 being fixedly connected to the swing arm 5; a protruding post 401 is mounted on the rotating sleeve 4; and a set of grooves is formed on the rotating shaft 8 that slidably engage with the protruding post 401.

[0043] As a further embodiment of the present invention, the groove group includes a horizontal groove 801 and an inclined groove 802 that are interconnected; the clamping member can be driven to move by the cooperation between the protruding post 401 and the inclined groove 802.

[0044] In this embodiment, the initial position is: the protruding post 401 is located in the inclined groove 802.

[0045] After the billet is conveyed to the middle position of the clamping mold 7, the motor 10 is controlled to rotate, which drives the second gear 11 to rotate, and through meshing, drives the third gear 12 to rotate, thereby driving the rotating shaft 8 to rotate. This causes the protruding column 401 to slide in the inclined groove 802 towards the transverse groove 801. Through the squeezing action of the protruding column 401 on the groove wall of the inclined groove 802, the rotating shaft 8 can be driven to move downward along its axis. During this process, the displacement of the rotating shaft 8 can drive the rack plate 17 away from the clamping arm 6, thereby driving the clamping molds 7 to move closer together to clamp the billet. During this process, the rotational resistance of the rotating sleeve 4 is greater than the squeezing force between the protruding column 401 and the inclined groove 802. Therefore, the rotating sleeve 4 does not rotate, and the swing arm 5 remains in a fixed position.

[0046] The rotating shaft 8 continues to rotate, causing the protruding post 401 to slide away from the inclined groove 802 in the transverse groove 801. During this process, the clamping mold 7 maintains the clamping state of the blank. When the protruding post 401 slides to the end of the transverse groove 801, the rotating shaft 8 will drive the rotating sleeve 4 to rotate synchronously through the squeezing action of the transverse groove 801 wall on the protruding post 401, so as to drive the blank to rotate and approach the processing table 3 through the clamping component. When it reaches the processing position, the motor 10 stops rotating. Then the milling module 2 will perform milling processing on the blank. During this process, the squeezing action of the transverse groove 801 wall on the protruding post 401 can ensure that the vertical position of the rotating shaft 8 does not change, so as to ensure that the clamping state of the clamping component on the blank remains unchanged (avoiding the squeezing force generated by milling from causing the blank to move on the clamping component and reducing the processing accuracy).

[0047] After processing, the motor 10 is driven by the meshing action of the second gear 11 and the third gear 12, and the rotating shaft 8 rotates in the opposite direction, so that the protruding column 401 slides in the transverse groove 801 in the direction of the inclined groove 802; during this process, the swing arm 5 does not rotate.

[0048] When the protruding post 401 slides to the connection between the horizontal groove 801 and the inclined groove 802, the squeezing action of the inclined groove 802 on the protruding post 401 can drive the rotating sleeve 4 to rotate synchronously (at this position, the resistance of the rotating sleeve 4 to rotate is less than the squeezing force of the inclined groove 802 on the protruding post 401).

[0049] The rotating sleeve 4 will drive the clamping parts to move synchronously through the swing arm 5, so as to drive the blank away from the processing table 3. When the swing arm 5 is reset, the resistance of the rotating sleeve 4 will be greater than the squeezing force of the inclined groove 802 on the protruding column 401. The rotating shaft 8, which continues to rotate, will drive the protruding column 401 to slide in the inclined groove 802. Through the squeezing action of the protruding column 401 on the groove wall of the inclined groove 802, the rotating shaft 8 can be driven to move upward along its axis, thereby driving the rack plate 17 to approach the clamping arm 6, so as to drive the clamping mold 7 to move away from each other, so as to release the blank.

[0050] The sequence of operations of the equipment is rigidly defined by the mechanical structure, forming a reliable mechanical interlock. It forces the system to "clamp the billet first, then convey it," and after processing, it must "return to a safe position first, then release the billet." This avoids dangerous situations such as "conveying without clamping" or "releasing at the processing position" that may occur due to program errors or signal interference, ensuring the safety of the equipment and operators, and making the operation extremely reliable.

[0051] As a further embodiment of the present invention, the conveying component further includes a fixed sleeve 9 installed on the support frame 1, the fixed sleeve 9 being slidably connected to the rotating shaft 8; a large spring 13 is provided inside the fixed sleeve 9; the two ends of the large spring 13 respectively abut against the rotating shaft 8 and the fixed sleeve 9.

[0052] In this embodiment, the spring constant of the large spring 13 is relatively large.

[0053] In the initial state, the rotating shaft 8 is located inside the fixed sleeve 9; during the clamping process, the compression of the large spring 13 increases.

[0054] After processing, the rotating shaft 8 rotates in the opposite direction. At this time, the inclined groove 802 squeezes the protruding column 401. The elastic force of the large spring 13 counteracts the upward movement of the rotating shaft 8, so that the resistance of the rotating sleeve 4 will be greater than the squeezing force of the inclined groove 802 on the protruding column 401, so that the rotating shaft 8 can drive the rotating sleeve 4 to rotate synchronously, thereby driving the swing arm 5 to reset.

[0055] As a further embodiment of the present invention, a limiting block 18 is fixed on the support frame 1, and a fixing block 402 that cooperates with the limiting block 18 is installed on the rotating sleeve 4.

[0056] In this embodiment, after the swing arm 5 is reset, the fixed block 402 abuts against the limiting block 18. At this time, the resistance of the rotating sleeve 4 to the rotation is increased by the abutting action of the limiting block 18 against the fixed block 402, so that the rotating shaft 8, which continues to rotate, cannot drive the swing arm 5 to rotate, thereby ensuring the stability of the equipment operation.

[0057] As a further embodiment of the present invention, a fixing ring 22 is installed on the rotating sleeve 4, and multiple sets of second toothed blocks 2201 are installed on the fixing ring 22 at equal intervals along its circumference; an mounting sleeve 19 is installed on the support frame 1; a sliding ring 20 is slidably fitted on the mounting sleeve 19; multiple sets of first toothed blocks 2001 are installed on the sliding ring 20 at equal intervals along its circumference, and the first toothed blocks 2001 mesh with the second toothed blocks 2201; a small spring 21 is wrapped around the mounting sleeve 19, and the two ends of the small spring 21 abut against the sliding ring 20 and the mounting sleeve 19 respectively.

[0058] In this embodiment, during the clamping process of the blank, the meshing action of the first tooth block 2001 and the second tooth block 2201 can increase the resistance to the rotation of the rotating sleeve 4. This allows the protruding post 401 to slide in the inclined groove 802, and the squeezing force of the groove wall of the inclined groove 802 on the protruding post 401 is less than the resistance to the rotation of the rotating sleeve 4. Therefore, during the clamping process, the swing arm 5 does not rotate, thereby improving the clamping accuracy.

[0059] After clamping, the rotating shaft 8 continues to rotate, pressing the protruding column 401 against the wall of the transverse groove 801. At this time, the pressing force is greater than the resistance, so the rotating sleeve 4 rotates synchronously. During the rotation, the fixed ring 22 rotates synchronously, so as to drive the second tooth block 2201 to press the first tooth block 2001, thereby causing the sliding ring 20 to move away from the fixed ring 22 along the axial direction of the mounting sleeve 19 and compress the small spring 21. When the second tooth block 2201 passes the first tooth block 2001, the elastic force of the small spring 21 will drive the sliding ring 20 to reset, so that the first tooth block 2001 and the second tooth block 2201 re-engage.

[0060] As a further embodiment of the present invention, a rotating ring 14 is rotatably mounted on the rotating shaft 8, a sliding block 16 is slidably fitted on the swing arm 5, the sliding block 16 is fixedly connected to the rack plate 17, and a connecting rod 15 hinged to the rotating ring 14 is rotatably mounted on the sliding block 16.

[0061] In this embodiment, when the rotating shaft 8 moves up or down along its axial direction, it will drive the rotating ring 14 to move synchronously, thereby driving the connecting rod 15 to move. The moving connecting rod 15 will drive the sliding block 16 to move away from or closer to the clamping arm 6 on the swing arm 5, so as to drive the rack plate 17 to move synchronously, thereby driving the clamping molds 7 to move closer or further away from each other, so as to clamp or release the blank.

[0062] The sequence of operations of the equipment is rigidly defined by the mechanical structure, forming a reliable mechanical interlock. It forces the system to "clamp the billet first, then convey it," and after processing, it must "return to a safe position first, then release the billet." This avoids dangerous situations such as "conveying without clamping" or "releasing at the processing position" that may occur due to program errors or signal interference, ensuring the safety of the equipment and operators, and making the operation extremely reliable.

[0063] As a further embodiment of the present invention, the surface of the clamping mold 7 is rough.

[0064] In this embodiment, the clamping mold 7 has a large coefficient of friction, which can prevent the blank from slipping during clamping and affecting the machining accuracy.

[0065] A method for controlling the feed and retraction of aluminum profile hot extrusion die sleeves using a vertical milling machine as described above includes the following steps: Step 1: Clamp the blank at the loading station using clamping components; Step 2: Use the conveyor to transport the blank held by the clamping device to the processing position; Step 3: Mill the blank according to the drawing requirements, keeping the clamping parts in a clamped state during the machining process; Step 4: After processing is completed, the finished or semi-finished product is transported to the loading station by the conveyor, and the clamping part is released after reaching the loading station.

[0066] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0067] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
