Description

Technical Field

[0001] This invention belongs to the field of automotive forged shaft production technology, specifically a fixed-length cutting device for thin forged shafts of new energy vehicles. Background Technology

[0002] With the booming development of the new energy vehicle industry, thin forged shafts are an important component of key parts for new energy vehicles, and the fixed-length cutting process in their production is crucial.

[0003] There are some technical problems in the existing fixed-length cutting technology for thin forged shaft parts for new energy vehicles:

[0004] Firstly, regarding the fixing of forged shafts, due to the differences in size between different batches and models of thin forged shafts for new energy vehicles, the existing fixing devices are difficult to adjust flexibly according to the actual size of the shafts. As a result, the forged shafts cannot be firmly fixed during the cutting process, which easily causes shaking or displacement, thereby affecting the cutting accuracy and the quality of the shafts.

[0005] Secondly, there is a lack of a stable and effective guiding mechanism during the pre-cutting position adjustment process. Existing devices often experience unstable guidance when pushing the forged shaft for position adjustment, resulting in inaccurate positioning of the shaft before cutting and further affecting the cutting accuracy.

[0006] Furthermore, existing cutting devices struggle to automatically adjust the cutting distance and stably clamp the forged shafts of varying sizes. In actual production, frequent manual adjustments to the cutting device parameters are necessary, which not only reduces production efficiency but also increases the impact of human error on cutting quality. Summary of the Invention

[0015] In one embodiment of the present invention, L-shaped fixing rods are provided on the outer sides of both the first guide block and the second guide block. The other ends of the two L-shaped fixing rods are connected to a connecting ring plate. The connecting ring plate is located on the outer side of the adaptive fixing block.

Detailed Implementation

[0036] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0037] The following describes a fixed-length cutting device for thin forged shaft parts for new energy vehicles, with reference to the accompanying drawings.

[0038] like Figures 1 to 10As shown, this embodiment of the invention provides a fixed-length cutting device for thin forged shaft parts of new energy vehicles, and an automatic trigger control component 2. The automatic trigger control component 2 includes a first guide block 4, a second guide block 5, an adaptive fixing block 6, an electric telescopic control button 9, and a cutter control button 10. The first guide block 4 and the second guide block 5 are located on both sides of the adaptive fixing block 6. One end of the forged shaft body 1 is inserted into the interior of the adaptive fixing block 6. The size of the adaptive fixing block 6 is adjusted according to the size of the forged shaft body 1. Connecting rods 7 are respectively provided on both sides of the outer wall of the adaptive fixing block 6. One end of the two connecting rods 7 is respectively located inside the first guide block 4 and the second guide block 5. The electric telescopic control button 9 is located inside the first guide block 4, and the cutter control button 10 is located inside the second guide block 5.

[0039] The electric expansion joint 16 is electrically connected to the electric expansion joint control button 9 via a transmission line. The adaptive fixing block 6 is driven by the extrusion force of the forged shaft body 1, which drives the connecting rod 7 to touch the electric expansion joint control button 9, and the electric expansion joint 16 automatically starts working. The cutter 32 is electrically connected to the cutter control button 10 via a transmission line. The adaptive fixing block 6 is driven by the extrusion force of the forged shaft body 1, which drives the connecting rod 7 to touch the cutter control button 10, and the cutter 32 automatically starts working.

[0040] In practical applications, the internal dimensions of the adaptive fixing block 6 can be flexibly adjusted according to the actual dimensions of the forged shaft body 1 to ensure that the device can be applied to forged shafts of different sizes, enhancing the versatility of the device. When the forged shaft is inserted into the adaptive fixing block 6, its outer wall is in close contact with the inner wall of the adaptive fixing block 6, forming a stable fixing effect, which not only improves cutting accuracy but also effectively prevents the forged shaft from shaking during the cutting process. One end of each of the two connecting rods 7 is connected to the outer wall of the adaptive fixing block 6, and the other end extends into the interior of the first guide block 4 and the second guide block 5, respectively. The first guide block 4 and the second guide block 5 are respectively located on both sides of the adaptive fixing block 6, serving as support and guides to ensure that the connecting rods 7 can move smoothly and steadily when subjected to force.

[0041] When the adaptive fixing block 6 is subjected to the extrusion force of the forged shaft, the force transmitted through the connecting rod 7 will trigger the corresponding control button, thereby activating the electric telescopic device 16 and the cutter 32. The electric telescopic device 16 can adjust the position of the forged shaft body 1 to provide a cutting starting point for the cutter 32. The cutter 32 then performs fast and accurate cutting on the forged shaft body 1 according to the preset cutting parameters.

[0042] According to the size of the forged shaft body 1 to be cut, adjust the internal size of the adaptive fixing block 6 to ensure that the forged shaft body 1 can be firmly fixed. Insert one end of the forged shaft body 1 into the interior of the adaptive fixing block 6 to ensure that the forged shaft body 1 is in close contact with the inner wall of the adaptive fixing block 6.

[0043] Once the forged shaft body 1 is fully fixed, its compressive force acts on the adaptive fixing block 6. Under this force, the adaptive fixing block 6 transmits the force to the electric telescopic control button 9 inside the first guide block 4 via the connecting rod 7. When the electric telescopic control button 9 is triggered, the electric telescopic device 16 automatically starts and adjusts the position of the forged shaft body 1 according to a preset program, preparing for the cutting operation. After the electric telescopic device 16 completes the position adjustment, the compressive force of the forged shaft body 1 continues to be transmitted through the connecting rod 7 to the cutter control button 1 inside the second guide block 5. When the cutter control button 1 is triggered, the cutter 32 automatically starts and performs a rapid and accurate cut on the forged shaft body 1 according to preset cutting parameters.

[0044] In one possible implementation, the fixed-length cutting device for thin forged shaft parts of new energy vehicles further includes: a forged shaft body 1, the outer wall of the forged shaft body 1 is provided with a first adaptive clamping plate 21 and a second adaptive clamping plate 22, the dimensions of the first adaptive clamping plate 21 and the second adaptive clamping plate 22 are adjusted according to the dimensions of the forged shaft body 1.

[0045] The working box 27 has mounting holes 30 on both sides of its outer wall. Each mounting hole 30 contains an embedded fixing block 18, and each embedded fixing block 18 contains a first hydraulic cylinder 19. The working ends of each first hydraulic cylinder 19 are equipped with elastic retractable guide rods 20. The other ends of the elastic retractable guide rods 20 are respectively located on the outer walls of the first adaptive clamping plate 21 and the second adaptive clamping plate 22. A shaft passage hole 31 is provided on one side of the outer wall of the working box 27. The shaft passage hole 31 facilitates the passage of one end of the forged shaft body 1. The size of the shaft passage hole 31 is determined according to the size of the forged shaft body 1. Adjustments are made; the inner wall of the first adaptive clamping plate 21 is provided with a fixing groove 23, the inner wall of the second adaptive clamping plate 22 is provided with an embedding block 26 that matches the fixing groove 23, the inner wall of the fixing groove 23 is provided with a positive ferrite magnetic strip 24, the outer wall of the embedding block 26 is provided with a negative ferrite magnetic strip 25 that matches the positive ferrite magnetic strip 24, the embedding block 26 extends into the interior of the fixing groove 23, and the positive ferrite magnetic strip 24 and the negative ferrite magnetic strip 25 are magnetically connected to each other; the outer wall of the working box 27 is provided with four sets of support columns 28, the bottom of each of the four sets of support columns 28 is provided with a protective plate, and the bottom surface of each of the four protective plates is provided with anti-slip texture.

[0046] In specific applications of this invention, the first adaptive clamping plate 21 and the second adaptive clamping plate 22 are adjusted according to the dimensions of the forged shaft body 1. The first hydraulic cylinder 19 provides driving force to ensure that the first adaptive clamping plate 21 and the second adaptive clamping plate 22 can firmly clamp the forged shaft body 1. At the same time, the elastic telescopic guide rod 20 not only serves a guiding function but also absorbs a certain amount of impact force during clamping, protecting the forged shaft body 1 from damage.

[0047] The magnetic connection between the positive ferrite magnetic strip 24 and the negative ferrite magnetic strip 25 not only simplifies the installation and disassembly process of the first adaptive clamping plate 21 and the second adaptive clamping plate 22, but also ensures the stability of the first adaptive clamping plate 21 and the second adaptive clamping plate 22 during the cutting process. The magnitude of the magnetic attraction force can be achieved by adjusting the size and magnetic strength of the positive ferrite magnetic strip 24 and the negative ferrite magnetic strip 25 to adapt to forging shaft bodies 1 of different sizes.

[0048] The protective plates installed at the bottom of the four sets of support columns 28 not only increase the stability of the equipment, but also the anti-slip texture on the bottom surface effectively prevents the equipment from sliding or shifting during operation. According to the size of the forged shaft body 1 to be cut, the first hydraulic cylinder 19 is activated. The first hydraulic cylinder 19 drives the elastic telescopic guide rod 20 at the output end to move, and then the elastic telescopic guide rod 20 drives the first adaptive clamping plate 21 and the second adaptive clamping plate 22 on one side to move on the outer wall of the forged shaft body 1 to reach the designated cutting position as a cutting mark.

[0049] In one possible implementation, the bottom of the inner cavity of the working box 27 is provided with two sets of auxiliary slide rails 3. The two sets of auxiliary slide rails 3 are located on both sides below the forging shaft body 1. The first guide block 4 and the second guide block 5 are respectively located inside the two sets of auxiliary slide rails 3. The two sets of auxiliary slide rails 3 are also provided with tension springs 11. The other ends of the two sets of tension springs 11 are respectively located on the outer walls of the first guide block 4 and the second guide block 5. The first guide block 4 and the second guide block 5 are also provided with buffer springs 8. The other ends of the two sets of buffer springs 8 are each located on the outer wall of the connecting rod 7. The outer sides of the first guide block 4 and the second guide block 5 are provided with L-shaped fixing rods 12. The other ends of the two L-shaped fixing rods 12 are connected to a connecting ring plate 13. The connecting ring plate 13 is located on the outer side of the adaptive fixing block 6. The size of the connecting ring plate 13 is larger than the outer size of the adaptive fixing block 6. The adaptive fixing block 6 is subjected to the extrusion force of the forged shaft body 1, which causes the adaptive fixing block 6 to enter the interior of the connecting ring plate 13. The outer wall of the adaptive fixing block 6 is provided with a positive electromagnet 14, and the inner wall of the connecting ring plate 13 is provided with a negative electromagnet 15. The positive electromagnet 14 and the negative electromagnet 15 are magnetically connected to each other.

[0050] In practical applications, the auxiliary slide rail 3 not only provides a smooth sliding track for the first guide block 4 and the second guide block 5, but also provides dynamic support and buffering during the movement or cutting of the forged shaft body 1 through the internal tension spring 11, ensuring the stability of the forged shaft body 1 during the cutting process. The buffer spring 8 added inside the first guide block 4 and the second guide block 5 further enhances this stability. It is tightly connected to the guide block through the connecting rod 7, effectively absorbing vibration and impact during the cutting process. The connecting ring plate 13 is larger than the adaptive fixing block 6, ensuring that the forged shaft can be firmly clamped regardless of changes in size, enhancing the adaptability of the device to forged shafts of different specifications.

[0051] The positive electromagnet 14 and the negative electromagnet 15 are magnetically connected. Before cutting, by activating the electromagnets, the adaptive fixing block 6 is firmly adsorbed inside the connecting ring plate 13, ensuring stable clamping of the forged shaft body 1 during the cutting process. After cutting, by de-energizing or reversing the activation of the electromagnets, the forged shaft body 1 can be quickly released, improving cutting efficiency.

[0052] In one possible implementation, the inner wall of the working box 27 is provided with an electric telescopic device 16. The working end of the electric telescopic device 16 is provided with a telescopic rod 17. There are two sets of telescopic rods 17. The other ends of the two sets of telescopic rods 17 are respectively provided on the outer walls of the first guide block 4 and the second guide block 5, driving the first guide block 4 and the second guide block 5 to move inside the two sets of auxiliary slide rails 3 respectively. The electric telescopic device 16 is electrically connected to the electric telescopic device control button 9 through a transmission line. The adaptive fixing block 6 is subjected to the extrusion force of the forged shaft body 1, which drives the adaptive fixing block 6 to drive the connecting rod 7 to touch the electric telescopic device control button 9, and the electric telescopic device 16 automatically starts working.

[0053] In a specific application of this invention, the electric telescopic device 16 is installed on the inner wall of the working box 27 to ensure the stability of the cutting operation. The telescopic rod 17, as the working end of the electric telescopic device 16, is connected to the outer wall of the first guide block 4 and the second guide block 5 respectively through two sets of symmetrical arrangement, which can enhance the stability and guidance of the first guide block 4 and the second guide block 5.

[0054] When the forged shaft body 1 is subjected to compressive force, the adaptive fixing block 6 can flexibly deform to fit tightly against the outer wall of the forged shaft. Simultaneously, the adaptive fixing block 6 is also connected to the electric expansion joint control button 9 via the connecting rod 7. When the forged shaft body 1 is placed on the cutting device, its compressive force drives the adaptive fixing block 6 to move, which in turn triggers the electric expansion joint control button 9 via the connecting rod 7, automating the cutting operation. Once the forged shaft body 1 is correctly positioned and sufficient compressive force is generated, the electric expansion joint 16 automatically starts operating without manual intervention.

[0055] The forged shaft body 1 to be cut is placed on the adaptive fixing block 6, ensuring that its position is correct and matches the alignment mark of the cutting device. After the forged shaft body 1 is subjected to the extrusion force of the adaptive fixing block 6, the adaptive fixing block 6 deforms moderately and fits tightly against the outer wall of the forged shaft body 1, while driving the connecting rod 7 to move to the position of touching the control button 9 of the electric telescopic device.

[0056] When the connecting rod 7 touches the control button 9 of the electric telescopic device, the sensor inside the control button detects the touch signal and transmits it to the microprocessor. After processing the signal, the microprocessor sends a start command to the electric telescopic device 16 via a transmission line. Upon receiving the start command, the electric telescopic device 16 responds quickly, driving the telescopic rod 17 to perform linear reciprocating motion, which in turn causes the first guide block 4 and the second guide block 5 to move smoothly within the auxiliary slide rail 3, thereby realizing the cutting operation of the forged shaft. After the cutting is completed, the electric telescopic device 16 automatically stops working, and the telescopic rod 17 retracts to its initial position.

[0057] In one possible implementation, a second hydraulic cylinder 34 is provided on the outside of the working box 27. A cutter 32 is provided at the working end of the second hydraulic cylinder 34. The cutter 32 is located above the forging shaft body 1. A shock-absorbing spring 33 is provided on the other side of the cutter 32. The other end of the shock-absorbing spring 33 is located on the inner wall of the working box 27. The cutter 32 is electrically connected to the cutter control button 10 through a transmission line. The adaptive fixing block 6 is subjected to the squeezing force of the forging shaft body 1, which drives the adaptive fixing block 6 to drive the connecting rod 7 to touch the cutter control button 10, and the cutter 32 automatically starts working.

[0058] In specific applications, the second hydraulic cylinder 34 can stably and quickly push the cutter 32 to move back and forth above the forged shaft body 1, thereby cutting the forged shaft body 1. The damping spring 33 effectively reduces the vibration and impact generated during the cutting process, protecting the cutter 32 and the working box 27 from damage. The damping spring 33 has good resilience and fatigue resistance, and can effectively absorb and disperse vibration energy when the cutter 32 is working, ensuring the smooth progress of the cutting operation.

[0059] The cutter control button 10 is electrically connected to the cutter 32 via a conductive line, enabling automatic control of the cutter 32. When the adaptive fixing block 6 is subjected to the extrusion force of the forged shaft body 1, it will drive the connecting rod 7 to move and touch the cutter control button 10, thus not only automating the start of the cutting operation but also improving cutting efficiency and safety. Simultaneously, the cutter control button 10 integrates a microprocessor and intelligent sensor components, which can accurately identify touch signals and quickly transmit them to the cutter 32, ensuring the timeliness and accuracy of the cutting action.

[0060] When the forged shaft body 1 is placed on the adaptive fixing block 6, the fixing block is subjected to extrusion pressure and undergoes moderate deformation, closely fitting the outer wall of the forged shaft body 1. The adaptive fixing block 6 drives the connecting rod 7 to move until it touches the cutter control button 10.

[0061] The sensor inside the cutter control button 10 detects a touch signal and transmits it to the microprocessor. After processing the signal, the microprocessor sends a start command to the cutter 32 via a transmission line. Upon receiving the start signal, the second hydraulic cylinder 34 begins to push the cutter 32 above the forged shaft body 1, moving it to the designated cutting position, and then cutting the forged shaft body 1. Under the push of the hydraulic cylinder, the blade of the cutter 32 cuts the forged shaft at a stable speed and force. Based on the size of the forged shaft body 1, the distance between the blade of the cutter 32 and the forged shaft body 1 is always maintained at a convenient cutting distance, so this device does not need to consider the vertical movement of the cutter 32.

[0062] After the cutter 32 completes the cutting operation, the second hydraulic cylinder 34 automatically stops working, and the cutter 32 retracts to its initial position.

[0063] In one possible implementation, the outer wall of the working box 27 is also provided with a control panel 29, which is electrically connected to the first hydraulic cylinder 19, the second hydraulic cylinder 34, the electric telescopic device 16 and the cutter 32 via conductive lines.

[0064] In specific applications of this invention, the hydraulic cylinder 19, the second hydraulic cylinder 34, the electric telescopic device 16, and the cutter 32 used in this device are all mature existing technologies. The working principles of the hydraulic cylinder 19, the second hydraulic cylinder 34, the electric telescopic device 16, and the cutter 32 are also well known to those skilled in the art, and will not be described in detail here.

[0065] Adjust the adaptive fixing block 6, the first adaptive clamping plate 21 and the second adaptive clamping plate 22 according to the size of the forged shaft body 1, insert one end of the forged shaft body 1 into the working box 27 through the shaft through hole 31, and make it firmly clamped by the clamping plate.

[0066] When the forged shaft body 1 is clamped, the adaptive fixing block 6 is subjected to compressive force, which causes the connecting rod 7 to touch the electric telescopic device control button 9. The electric telescopic device 16 is activated, and the telescopic rod 17 pushes the first guide block 4 and the second guide block 5 to move within the auxiliary slide rail 3 to adjust the position of the forged shaft body 1.

[0067] After the forged shaft is positioned, the adaptive fixing block 6 continues to be stressed and drives the connecting rod 7 to touch the cutter control button 10. The cutter 32 starts and precisely cuts the forged shaft body 1.

[0068] After cutting, the electric telescopic device 16 and the cutter 32 are reset by the action of the tension spring 11 and the buffer spring 8, respectively. At the same time, the clamping plate is released from the forged shaft body 1 by the drive of the first hydraulic cylinder 19, ready for the next operation.
