Description

Technical Field

[0001] This invention relates to the field of parts processing technology, specifically a cutting device for processing automotive parts using new materials. Background Technology

[0002] In the automotive parts manufacturing industry, cutting devices are indispensable and crucial equipment when processing automotive parts using new materials. Through the coordinated work of components such as lathes and milling cutters, cutting devices precisely machine automotive parts to meet the high precision requirements of automobile manufacturing. Among these, the milling cutter, as a key component directly involved in the cutting operation, has a significant impact on the entire machining process due to the ease of its installation and disassembly.

[0003] Existing automotive parts cutting devices mostly employ traditional bolt fixing or snap-fit ​​connections for milling cutter installation and removal. Bolt fixing requires operators to tighten or loosen each bolt individually with tools, a cumbersome process. Furthermore, after repeated installation and removal, bolts are prone to stripping, affecting the stability and reliability of the installation. While snap-fit ​​connections are simpler to operate, they are susceptible to elastic fatigue after prolonged use, leading to weak connections. Additionally, snap-fit ​​connections may deform and become difficult to separate during disassembly, increasing the difficulty of removal. These structural designs result in time-consuming milling cutter installation and removal processes. Frequent downtime when milling cutters need replacement severely impacts production continuity, leading to low production efficiency. Moreover, the complexity of the process increases the risk of improper installation, affecting the machining accuracy and quality of automotive parts. Therefore, this invention provides a cutting device for machining automotive parts using new materials to solve the aforementioned problems. Summary of the Invention

[0004] The purpose of this invention is to provide a cutting device for processing automotive parts using new materials, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A cutting device for machining automotive parts using new materials includes a lathe.

A spring is fixedly connected to the upper side wall inside the second T-shaped slide groove, and the free end of the spring is fixedly connected to the side wall adjacent to the corresponding second T-shaped slider.

[0009] As a further embodiment of the present invention, the inner wall of the mounting groove is provided with a guide groove, and the outer wall of the connecting block is fixedly connected with a guide block that can be movably engaged inside the guide groove.

[0010] As a further embodiment of the present invention, the auxiliary mechanism includes a turbine and a connecting rod. The output shaft of the main shaft motor is located above the mounting block and is movably connected to the turbine via a bearing. The lower wall of the turbine is fixedly connected to the connecting rod, which is a Z-shaped block. The lower end of the outer wall of the connecting rod on the clockwise side is set as an arc surface.

[0011] As a further embodiment of the present invention, a limiting groove is provided at the lower end of the outer wall surface of the connecting rod, and the limiting groove is located at the lower end of the counterclockwise side of the outer wall surface of the connecting rod.

[0012] As a further embodiment of the present invention, the driving mechanism includes a servo motor, a worm gear, and an electric telescopic rod. A movable servo motor is provided on the upper wall of the horizontal end of the L-shaped motor mounting bracket. The output shaft of the servo motor is fixedly connected to a worm gear that can mesh with the worm gear.

[0014] As a further embodiment of the present invention, the guide rail mechanism includes a first slide rail, a first sliding component, a second slide rail, and a second sliding component. Two first slide rails are symmetrically fixedly installed on the lathe via columns. Each of the two first slide rails is equipped with a first sliding component that can slide on the first slide rail. A second slide rail is fixedly connected between the two first sliding components. A second sliding component that can slide on the second slide rail is equipped with a second sliding component that can slide on the second slide rail. The second sliding component is fixedly connected to the spindle motor.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. In use, this invention utilizes a limiting mechanism consisting of a first movable slot, a driven block, a second movable slot, an active block, and a lever, in conjunction with a guide groove on the inner wall of the mounting slot and a guide block on the outer wall of the connecting block, to achieve rapid installation and removal of the milling cutter. During installation, the active block and driven block automatically engage; during replacement, the lever can be used to separate them. This solves the problems of cumbersome and time-consuming installation and removal operations for milling cutters in existing automotive parts cutting devices, leading to low production efficiency and frequent downtime affecting processing continuity.

[0017] 2. In use, this invention utilizes the worm gear and connecting rod of the auxiliary mechanism, in conjunction with the servo motor, worm gear, and electric telescopic rod of the drive mechanism. When the milling cutter is damaged due to high temperature, the electric telescopic rod drives the servo motor to engage the worm gear and worm gear, driving the connecting rod to press the lever, achieving contactless disassembly. This solves the problem of existing automotive parts cutting devices where the milling cutter cannot be replaced in time when it is at a high temperature, requiring waiting for cooling, thus delaying production progress and reducing production efficiency.

[0018] 3. In use, this invention utilizes the limiting slot at the lower end of the outer wall of the auxiliary mechanism connecting rod and the lever of the limiting mechanism. The worm gear controls the connecting rod to rotate counterclockwise, causing the lever to enter the limiting slot and restricting its displacement. This solves the problem in existing automotive parts cutting devices where the milling cutter easily loosens due to vibration during processing, leading to decreased machining accuracy and unstable product quality.

[0019] 4. When using this invention, the guide groove inside the mounting slot can limit the position and orientation of the connecting block when installing the milling cutter. This ensures that after the connecting block is inside the mounting slot, the second movable slot on the connecting block is aligned with the first movable slot on the mounting block. This ensures that the milling cutter can be installed and replaced quickly and effectively. At the same time, it also ensures that the connecting block will not rotate when the mounting block drives the connecting block to rotate, thus preventing it from affecting the machining operation.

[0030] 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.

[0031] Please see Figures 1-9In this embodiment of the invention, a cutting device for processing automotive parts using new materials includes a lathe 1. A spindle motor 6, capable of free movement on the lathe 1, is mounted on the lathe 1 via a guide rail mechanism. The spindle motor 6 is electrically connected to an external power source. A milling cutter 7 for cutting automotive parts is mounted on the spindle motor 6. During use, the spindle motor 6 is started by an external power source, driving the milling cutter 7 to rotate and complete the cutting operation of the corresponding automotive part. A clamping block 8 is mounted on the lathe 1 to fix the automotive parts to be processed, thereby facilitating their processing. A mounting block 9 is fixedly connected to the lower end of the output shaft of the main spindle motor 6. A mounting groove 10 is provided on the lower end face of the mounting block 9. A connecting block 11 is movably engaged inside the mounting groove 10. The milling cutter 7 is fixedly connected to the lower end face of the connecting block 11. A limiting mechanism for quickly disassembling and installing the connecting block 11 is provided on the mounting block 9. An auxiliary mechanism for enhancing the connection stability between the mounting block 9 and the connecting block 11 is provided on the output shaft of the main spindle motor 6. An L-shaped motor mounting bracket 27 is fixedly connected to the outside of the main spindle motor 6. A drive mechanism for driving the auxiliary mechanism is provided on the L-shaped motor mounting bracket 27.

[0032] The limiting mechanism includes a first movable slot 12, a driven block 13, a second movable slot 17, an active block 18, and a lever 16. The inner wall of the mounting groove 10 has the first movable slot 12, which extends through and connects to the outer side of the mounting block 9. The outer wall of the connecting block 11 has the second movable slot 17 corresponding to the first movable slot 12. When the connecting block 11 is fully inserted into the mounting groove 10, the position of the second movable slot 17 corresponds to the position of the first movable slot 12, and the interior of the first movable slot 12 is movably engaged with a lever. A rotatable driven block 13 is attached to the second movable slot 17, where a rotatable driving block 18 is movably engaged. Both the driven block 13 and the driving block 18 are semi-circular in cross-section. The driven block 13 and the driving block 18 are matched in shape and size and are mirror images of each other. A lever 16 is fixedly connected to the outer wall of the driven block 13 on the side away from the mounting slot 10. The end of the lever 16 away from the driven block 13 extends to the outside of the mounting block 9. When the lever 16 is not subjected to external force, it will be in a downward tilted state. Figure 3 As shown.

[0033] The inner wall of the first movable slot 12 has two symmetrically formed first T-shaped grooves 14. Each of the two first T-shaped grooves 14 has a first T-shaped slider 15 movably engaged inside it. The end of the first T-shaped slider 15 furthest from the corresponding first T-shaped groove 14 is fixedly connected to the side wall adjacent to the driven block 13. The driven block 13 is movably engaged inside the first movable slot 12 through the cooperation of the first T-shaped grooves 14 and the first T-shaped slider 15. The inner wall of the second movable slot 17 has two symmetrically formed second T-shaped grooves 19. Both the first T-shaped grooves 14 and the second T-shaped grooves 19 are arc-shaped grooves. Each of the two second T-shaped grooves 19 has a first T-shaped slider 15 movably engaged inside it. A second T-shaped slider 21 is attached to the movable slot. The end of the second T-shaped slider 21 furthest from the corresponding second T-shaped groove 19 is fixedly connected to the side wall adjacent to the active block 18. The active block 18 is movably engaged inside the second movable slot 17 via the cooperation of the second T-shaped groove 19 and the second T-shaped slider 21. A spring 20 is fixedly connected to the upper side wall inside the second T-shaped groove 19. The free end of the spring 20 is fixedly connected to the side wall adjacent to the corresponding second T-shaped slider 21. Because the spring 20 is installed inside the second T-shaped groove 19, the active block 18 will rotate and extend to the outside of the connecting block 11 under the elastic force of the spring 20. Figure 3 As shown.

[0034] When the connecting block 11 is inserted into the mounting slot 10, the driving block 18 is squeezed and rotated into the second movable slot 17 as it enters the mounting slot 10. At this time, the spring 20 is deformed by the second T-shaped slider 21. When the connecting block 11 is fully inserted into the mounting slot 10, the positions of the first movable slot 12 and the second movable slot 17 relative to the driving block 18 are no longer compressed. The lower end of the driving block 18 will then enter the first movable slot 12 under the elastic force of the spring 20, causing the upper end of the driven block 13 to enter the second movable slot 17. At this time, the lever 16 changes position with the rotation of the driven block 13 and tilts upward. Figure 4 As shown, the connecting block 11 is engaged with the mounting block 9, thus completing the installation of the milling cutter 7. At this time, the spindle motor 6 can drive the milling cutter 7 to rotate through the mounting block 9 to complete the cutting operation. When the milling cutter 7 is damaged and needs to be replaced, the lever 16 can be pushed down to reset it. At this time, the driven block 13 rotates under the drive of the lever 16, and presses the driving block 18 again to retract into the second movable slot 17. At this time, the connecting block 11 will separate from the inside of the mounting slot 10 by gravity. At this time, the operator can easily remove the milling cutter 7 by holding it, thus completing the replacement of the damaged milling cutter 7. The operation is simple and quick, which can improve work efficiency.

[0035] The inner wall of the mounting groove 10 is provided with a guide groove 22, and the outer wall of the connecting block 11 is fixedly connected with a guide block 23 that can be movably engaged inside the guide groove 22.

[0036] By using the guide groove 22 inside the mounting groove 10, the position and orientation of the connecting block 11 can be limited when the milling cutter 7 is installed. This ensures that after the connecting block 11 is inside the mounting groove 10, the second movable slot 17 on the connecting block 11 can be aligned with the first movable slot 12 on the mounting block 9. This ensures that the milling cutter 7 can be installed and replaced quickly and effectively. At the same time, it also ensures that the connecting block 11 will not rotate on its own when the mounting block 9 drives the connecting block 11 to rotate, thus preventing it from affecting the machining operation.

[0037] The auxiliary mechanism includes a turbine 24 and a connecting rod 25. The output shaft of the main shaft motor 6 is located above the mounting block 9 and is movably connected to the turbine 24 via a bearing. The lower wall of the turbine 24 is fixedly connected to the connecting rod 25, which is a Z-shaped block. The lower end of the connecting rod 25 is close to but does not contact the outer wall of the mounting block 9. The horizontal height of the lower end of the connecting rod 25 is lower than the horizontal height of the lever 16 when it is tilted upwards. The lower end of the outer wall of the connecting rod 25 on the clockwise side is set with an arc surface. The arc surface of the connecting rod 25 corresponds to the position of the connection between the lever 16 and the driven block 13 when the lever 16 is tilted upwards.

[0038] A limiting slot 26 is provided at the lower end of the outer wall surface of the connecting rod 25. The limiting slot 26 is located at the lower end of the counterclockwise side of the outer wall surface of the connecting rod 25. The position of the limiting slot 26 corresponds to the position of the connection between the lever 16 and the driven block 13 when the lever 16 is tilted upwards. Figure 2 As shown.

[0039] The drive mechanism includes a servo motor 28, a worm gear 29, and an electric telescopic rod 32. A movable servo motor 28 is mounted on the upper wall of the horizontal end of the L-shaped motor mounting bracket 27. The output shaft of the servo motor 28 is fixedly connected to a worm gear 29 that meshes with the worm 24. An electric telescopic rod 32 for driving the servo motor 28 is fixedly mounted on the horizontal end of the L-shaped motor mounting bracket 27, located on one side of the servo motor 28. The output shaft of the electric telescopic rod 32 is fixedly connected to the outer wall of the servo motor 28. By moving the servo motor 28 via the electric telescopic rod 32, the movement of the worm gear 29 can be controlled to ensure that the worm gear 29 meshes with the worm 24. When the worm gear 24 is engaged, and the electric telescopic rod 32 drives the servo motor 28 to move away from the electric telescopic rod 32, the worm 29 and the worm gear 24 disengage and do not engage. Conversely, when the worm 29 and the worm gear 24 are engaged, the electric telescopic rod 32 drives the servo motor 28 to move when the spindle motor 6 drives the milling cutter 7 to perform operations, causing the worm 29 and the worm gear 24 to separate, without affecting the normal operation of the equipment. Both the servo motor 28 and the electric telescopic rod 32 are existing technologies and will not be discussed here. Both the servo motor 28 and the electric telescopic rod 32 are electrically connected to an external power source, and the connection methods are existing connection methods and will not be discussed here.

[0040] The upper horizontal wall of the L-shaped motor mounting bracket 27 is provided with a third T-shaped groove 30 corresponding to the position of the servo motor 28. The third T-shaped groove 30 is movably engaged with a third T-shaped slider 31. The lower end of the servo motor 28 is fixedly connected to the side wall adjacent to the third T-shaped slider 31. Through the cooperation of the third T-shaped groove 30 and the third T-shaped slider 31, the servo motor 28 can be moved on the L-shaped motor mounting bracket 27.

[0041] Because the lower end of the connecting rod 25 is lower than the horizontal height of the lever 16 when it is tilted upwards, and the lower end of the outer wall of the connecting rod 25 on the clockwise side is an arc-shaped surface, the arc-shaped surface of the connecting rod 25 corresponds to the position of the connection between the lever 16 and the driven block 13 when it is tilted upwards. Therefore, if the milling cutter 7 is damaged during the cutting operation of the automotive parts, and the milling cutter 7 is in a high-temperature state and cannot be replaced by the operator in time, the electric telescopic rod 32 drives the servo motor 28 to move towards the side closer to the electric telescopic rod 32, so that the worm gear 29 meshes with the worm 24. At this time, the servo motor is driven... The machine 28 drives the worm 29 to rotate. Since the worm 29 meshes with the turbine 24, the worm 29 can drive the turbine 24 to rotate clockwise, thereby driving the connecting rod 25 to rotate clockwise along the outer side of the mounting block 9 until the arc surface on the connecting rod 25 contacts the lever 16. The lever 16 can then move downward under the pressure of the arc surface of the connecting rod 25, causing the driven block 13 to press the driving block 18 to reset. The connecting block 11 separates from the interior of the mounting groove 10 under the action of gravity, thus completing the disassembly of the milling cutter 7 without contact. This solves the problem that the milling cutter 7 cannot be replaced in time when it is at a high temperature, which leads to a decrease in production efficiency.

[0042] Since the limiting slot 26 is located at the lower end of the counterclockwise side of the outer wall of the connecting rod 25, the position of the limiting slot 26 corresponds to the position of the lever 16 when it is tilted upward and connected to the driven block 13. Therefore, in use, the connecting rod 25 can be controlled to rotate counterclockwise by rotating the worm gear 29, so that the lever 16 enters the interior of the limiting slot 26. Under the limitation of the limiting slot 26, the position of the lever 16 will not be displaced, thereby improving the stability of the connection between the milling cutter 7 and the mounting block 9.

[0043] The guide rail mechanism includes a first slide rail 2, a first sliding component 3, a second slide rail 4, and a second sliding component 5. Two first slide rails 2 are symmetrically fixedly installed on the lathe 1 via columns. Each of the two first slide rails 2 is equipped with a first sliding component 3 that can slide on the first slide rail 2. A second slide rail 4 is fixedly connected between the two first sliding components 3. A second sliding component 5 that can slide on the second slide rail 4 is equipped on the second slide rail 4. The second sliding component 5 is fixedly connected to the spindle motor 6. Through the first slide rail 2, the first sliding component 3, the second slide rail 4, and the second sliding component 5, the spindle motor 6 can be driven to move freely and flexibly on the lathe 1 during use. The first slide rail 2, the first sliding component 3, the second slide rail 4, and the second sliding component 5 are all existing technologies and will not be discussed here.

[0044] The working principle of this invention is:

[0045] When the connecting block 11 is inserted into the mounting groove 10, the active block 18 is squeezed and rotated into the second movable slot 17 as it enters the mounting groove 10. At this time, the spring 20 is deformed by the second T-shaped slider 21. When the connecting block 11 is fully inserted into the mounting groove 10, the positions of the first movable slot 12 and the second movable slot 17 relative to the active block 18 are no longer compressed. The lower end of the active block 18 will then enter the first movable slot 12 under the action of the spring force of the spring 20, thereby causing the upper end of the driven block 13 to enter the second movable slot 17. At this time, the lever 16 changes position as the driven block 13 rotates. The milling cutter 7 is then installed by tilting the milling cutter upwards. At this point, the connecting block 11 engages with the mounting block 9, thus completing the installation of the milling cutter 7. The spindle motor 6 can then drive the milling cutter 7 to rotate via the mounting block 9 to complete the cutting operation. When the milling cutter 7 is damaged and needs to be replaced, the lever 16 can be pushed downwards to reset it. At this point, the driven block 13 rotates under the drive of the lever 16, pressing the driving block 18 again to retract into the second movable slot 17. The connecting block 11 will then separate from the inside of the mounting slot 10 under the action of gravity. The operator can then easily remove the milling cutter 7 by holding it, thus completing the replacement of the damaged milling cutter 7. The operation is simple and quick, which can improve work efficiency.

[0046] Because the lower end of the connecting rod 25 is lower than the horizontal height of the lever 16 when it is tilted upwards, and the lower end of the outer wall of the connecting rod 25 on the clockwise side is an arc-shaped surface, the arc-shaped surface of the connecting rod 25 corresponds to the position of the connection between the lever 16 and the driven block 13 when it is tilted upwards. Therefore, if the milling cutter 7 is damaged during the cutting operation of the automotive parts, and the milling cutter 7 is in a high-temperature state and cannot be replaced by the operator in time, the electric telescopic rod 32 drives the servo motor 28 to move towards the side closer to the electric telescopic rod 32, so that the worm gear 29 meshes with the worm 24. At this time, the servo motor is driven... The machine 28 drives the worm 29 to rotate. Since the worm 29 meshes with the turbine 24, the worm 29 can drive the turbine 24 to rotate clockwise, thereby driving the connecting rod 25 to rotate clockwise along the outer side of the mounting block 9 until the arc surface on the connecting rod 25 contacts the lever 16. The lever 16 can then move downward under the pressure of the arc surface of the connecting rod 25, causing the driven block 13 to press the driving block 18 to reset. The connecting block 11 separates from the interior of the mounting groove 10 under the action of gravity, thus completing the disassembly of the milling cutter 7 without contact. This solves the problem that the milling cutter 7 cannot be replaced in time when it is at a high temperature, which leads to a decrease in production efficiency.

[0047] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
