Description

Technical Field

[0001] This invention relates to the field of thin-walled aluminum alloy transmission box processing technology, and in particular to a production line for processing thin-walled aluminum alloy transmission boxes. Background Technology

[0002] Thin-walled aluminum alloy transmission housings have been widely used in numerous industries, including automotive manufacturing and construction machinery, due to their significant advantages such as light weight and excellent heat dissipation. In actual production, thin-walled aluminum alloy transmission housings are mostly formed using turning processes. This processing method allows for precise control of the housing structure, effectively ensuring that the transmission housing has sufficient strength to meet its usage requirements under complex working conditions.

[0003] Currently, assembly line operations are commonly used for processing transmission gearboxes. However, this model has some significant drawbacks: the entire processing equipment occupies a large area and its layout is not compact or rational; the processing flow encompasses multiple stages, including loading, turning, and inspection. Especially after the turning process, the gearbox needs to be transported from the turning equipment to the inspection equipment. This additional transportation step not only increases the complexity of the operation but also consumes a significant amount of time and manpower, resulting in a substantial decrease in overall work efficiency and failing to meet the demands of modern industrial production for high efficiency and speed.

[0004] Based on this, this application proposes a production line for processing thin-walled aluminum alloy transmission housings, aiming to solve the problems of low efficiency in existing processing methods. Summary of the Invention

[0005] The purpose of this invention is to solve the above-mentioned technical problems by proposing a production line for processing thin-walled aluminum alloy transmission boxes.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A production line for processing thin-walled aluminum alloy transmission boxes includes a base, on which a worktable capable of intermittent rotation is provided. A placement groove is provided on the worktable, and a material discharge chute communicating with the placement groove runs through the worktable. A transmission box to be turned is placed in the placement groove. A mounting plate is fixed to the base, and a movable square column is mounted on the mounting plate. Four sliders capable of synchronous movement are provided on the four outer sides of the square column. The sliders reciprocate on the outer surfaces and their movement speed changes accordingly to the square column. A first laser scanner is mounted on each slider to inspect the four inner walls of the transmission box. A moving block that moves synchronously with the sliders is provided at the end of the square column, and a second laser scanner is mounted on the moving block to inspect the rear inner wall of the transmission box.

[0007] Preferably, a cam divider is installed on the base, and the shaft end of the cam divider is coaxially and fixedly connected to the bottom of the worktable.

[0008] Preferably, four support rods are fixed on the base, and a circular track is fixed to the bottom of the four support rods. The bottom of the worktable is slidably connected to the circular track.

[0009] Preferably, a fixing frame is mounted on the base, a driving component is mounted on the fixing frame, the output end of the driving component is connected to a turning device, and the driving component can drive the turning device to move.

[0010] Preferably, a clamping fixture is installed on the fixing frame, and the clamping fixture is arranged opposite to the upper end of the transmission box.

[0011] Preferably, the mounting plate is equipped with a motor, the output end of the motor is fixed with a drive rod, the output end of the drive rod is fixed with a screw, and the screw is threadedly connected to a square column.

[0012] Preferably, a support plate is fixed on the mounting plate, two guide rails are fixed on the support plate, a movable plate is slidably connected on the guide rails, a movable frame is fixed on the movable plate, and the square column is fixed inside the movable frame.

[0013] Preferably, each of the four corners of the square column is provided with a mounting groove, and a sprocket is rotatably connected in the mounting groove. The four sprockets are connected by a chain, and the slider is fixed on the chain. The square column is provided with a guide rail, and a sliding sleeve slides on the guide rail. The slider is fixed on the sliding sleeve.

[0014] Preferably, the system further includes a transmission mechanism, which comprises a short shaft rotatably mounted on a mounting plate. Transmission wheels are fixed to both the short shaft and the drive rod. The two transmission wheels are connected by a transmission belt. A rectangular sleeve is fixed to the short shaft, and a rectangular rod is slidably connected inside the rectangular sleeve. A transmission rod is fixed to the rectangular rod, which passes through and is rotatably connected to the movable frame. A first bevel gear is fixed to the transmission rod. Two positioning blocks are fixed to the square column, and a reciprocating screw is rotatably connected to each positioning block. A connecting shaft is fixed to the upper end of the reciprocating screw, and a second bevel gear is fixed to the connecting shaft. The first and second bevel gears mesh with each other. A drive block is fitted onto the reciprocating screw and is fixedly connected to the slider.

[0015] Preferably, an L-shaped rod is fixed on the slider, an inclined guide plate is fixed to the end of the square column, the moving block slides on the guide plate, and the L-shaped rod passes through the moving block and is slidably connected to it.

[0016] Compared with the prior art, the beneficial effects of this invention are as follows: 1. Because the worktable is set in a circular plate shape and the entire device is located on the base, the space occupied is greatly reduced; compared with the existing technology, there is no need to move the processed transmission box afterward, which improves work efficiency.

[0017] 2. The first laser scanner mounted on the slider moves along a sinusoidal path, enabling comprehensive inspection of the four inner walls of the transmission box; the second laser scanner mounted on the moving block inspects the rear inner wall of the transmission box, and the slider's moving speed can be adjusted according to the moving speed of the square column to ensure comprehensive inspection of the inner walls and timely detection of processing defects and other problems.

[0018] 3. If the square column moves at a high speed, the transmission through the drive wheel and drive belt will increase the speed of the reciprocating screw, thereby increasing the speed of the drive block's reciprocating movement. Conversely, if the speed decreases, the speed can be fully inspected on the inner wall.

[0019] 4. The reciprocating movement of the sliders drives the reciprocating movement of the chains, thus enabling the four sliders and four first laser scanners to move back and forth. During the movement of the square column, the sprockets in its four corner mounting slots rotate under the drive of the chains. Since the sliders are fixed to the chains and are also slidably connected to the guide rails on the square column through sliding sleeves, the four sliders can move synchronously when the chains move. The first laser scanners mounted on the sliders move along a sinusoidal path, enabling comprehensive inspection of the four inner walls of the transmission box to detect processing defects and other problems. This simultaneous inspection of the inner walls greatly improves inspection efficiency.

[0020] 5. The motor provides power, enabling not only the movement of the square column and the laser scanner, but also the movement of the laser scanner on the square column, without the need for additional power equipment.

[0021] In summary, the production line of this invention integrates turning and inner wall inspection, eliminating the need to transport the box from the turning equipment to the inspection equipment. This reduces the complexity of the operation process, saves a significant amount of time and manpower, improves overall work efficiency, and meets the requirements of modern industrial production for high efficiency and speed.

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0025] Reference Figures 1-7 A production line for processing thin-walled aluminum alloy transmission boxes includes a base 1, on which a worktable 7 capable of intermittent rotation is mounted. A cam divider 6 is installed on the base 1, and the shaft end of the cam divider 6 is coaxially and fixedly connected to the bottom of the worktable 7. Four support rods 4 are fixed on the base 1, and circular tracks 5 are fixed to the bottom of the four support rods 4. The bottom of the worktable 7 is slidably connected to the circular tracks 5, thus ensuring stable rotation of the worktable 7.

[0026] The worktable 7 is equipped with a placement slot 9, and a discharge chute 24, which communicates with the placement slot 9, runs through the worktable 7 to discharge cutting debris. For better debris collection, a dedicated debris collection device, such as a drawer-type collection box, can be installed under the worktable 7 for convenient periodic cleaning. The transmission box 8 to be turned is placed inside the placement slot 9, allowing it to be limited from four directions to ensure its stability. The dimensions of the placement slot 9 can be customized to accommodate different specifications of transmission boxes 8 to meet diverse production needs.

[0027] A fixed frame 2 is mounted on the base 1, and a drive component 10 is mounted on the fixed frame 2. The output end of the drive component 10 is connected to a turning machine 11, and the drive component 10 can drive the turning machine 11 to move. The drive component 10 can be a cylinder, a hydraulic cylinder, or an electric push rod. In actual selection, it is necessary to make a reasonable choice according to the specific requirements of the production line, such as load size and movement speed accuracy. For example, for occasions with large loads and high speed accuracy requirements, a hydraulic cylinder can be selected; while for occasions with small loads and flexible speed and position control requirements, an electric push rod is more suitable. Among them, a clamping fixture 13 is mounted on the fixed frame 2. The clamping fixture 13 is set opposite to the upper end of the transmission box 8, and can position the transmission box 8 from the top. The clamping fixture 13 can be made of elastic material, such as a rubber pad, which can ensure reliable positioning of the transmission box 8 and avoid damage to the surface of the transmission box 8.

[0028] A mounting plate 3 is fixed on the base 1. A movable square column 17 is mounted on the mounting plate 3. A motor 14 is mounted on the mounting plate 3. A drive rod 22 is fixed to the output end of the motor 14. A screw 26 is fixed to the output end of the drive rod 22. The screw 26 is threadedly connected to the square column 17. The square column 17 has a threaded groove, and the screw 26 engages with the threaded groove. To ensure the reliability and service life of the threaded connection, the screw 26 and the threaded groove can be made of high-strength, wear-resistant materials and undergo surface hardening treatment to improve their hardness and wear resistance.

[0029] A support plate 12 is fixed on the mounting plate 3. Two guide rails 27 are fixed on the support plate 12. A movable plate 15 is slidably connected to the guide rails 27. A movable frame 16 is fixed on the movable plate 15. The square column 17 is fixed inside the movable frame 16. In this way, the movable frame 16 and the square column 17 can be guided to ensure their stable movement. The guide rails 27 can be linear guide rails, which have the advantages of high motion accuracy, low frictional resistance, and long service life, and can effectively ensure the smoothness and accuracy of the movement of the square column 17.

[0030] The square column 17 has four sliders 36 that can move synchronously on its four outer sides. Each of the four corners of the square column 17 has a mounting groove 39, within which a sprocket 40 is rotatably connected. The four sprockets 40 are connected by a chain 41, and the sliders 36 are fixed to the chain 41. The square column 17 has a guide rail 35, on which a sliding sleeve 37 slides. The sliders 36 are fixed to the sliding sleeve 37. Thus, when the chain 41 moves, the four sliders 36 can move synchronously through the transmission of the sprockets 40. The chain 41 and sprockets 40 should be high-precision, low-noise products, and should be regularly lubricated and maintained to reduce wear and noise, and improve the stability and reliability of the transmission.

[0031] It also includes a transmission mechanism, which includes a short shaft 21 rotatably mounted on the mounting plate 3. Transmission wheels 25 are fixed on both the short shaft 21 and the drive rod 22. The two transmission wheels 25 are connected by a transmission belt 23. A rectangular sleeve 18 is fixed on the short shaft 21. A rectangular rod 19 is slidably connected inside the rectangular sleeve 18. A transmission rod 20 is fixed on the rectangular rod 19. The transmission rod 20 passes through the movable frame 16 and is rotatably connected to it. A first bevel gear 28 is fixed on the transmission rod 20. Two positioning blocks 33 are fixed on the square column 17. A reciprocating screw 32 is rotatably connected to the positioning blocks 33. A connecting shaft 31 is fixed to the upper end of the reciprocating screw 32. A second bevel gear 30 is fixed on the connecting shaft 31. The first bevel gear 28 and the second bevel gear 30 mesh with each other. A drive block 34 is fitted on the reciprocating screw 32 and is fixedly connected to the slider 36.

[0032] The slider 36 reciprocates on the outer surface and its movement speed changes accordingly with that of the square column 17. A first laser scanner 38 is mounted on the slider 36, which inspects the four inner walls of the transmission box 8. A moving block 43, which moves synchronously with the slider 36, is mounted on the moving block 43, which is equipped with a second laser scanner 44 to inspect the rear inner wall of the transmission box 8. An L-shaped rod 29 is fixed to the slider 36, and an inclined guide plate 42 is fixed to the end of the square column 17. The moving block 43 slides on the guide plate 42, and the L-shaped rod 29 passes through and slidably connects to the moving block 43. The first laser scanner 38 and the second laser scanner 44 should be high-precision, high-resolution products capable of accurately detecting minute defects on the inner wall of the transmission box 8.

[0033] The workflow is as follows: First, the cam divider 6 on the base 1 begins to operate, its shaft driving the worktable 7, which is coaxially fixed to it, to rotate intermittently. The bottom of the worktable 7 is slidably connected to the circular rails 5 fixed to the bottom of the four support rods 4, ensuring the stability of the worktable 7 during rotation. To further improve the accuracy and stability of the worktable 7's rotation, positioning devices such as positioning pins or photoelectric sensors can be installed on the circular rails 5 to ensure that the worktable 7 rotates to the accurate position each time.

[0034] When the worktable 7 stops at the appropriate position, the transmission box 8 to be machined is placed in the placement slot 9 on the worktable 7. The placement slot 9 limits the transmission box 8 from four directions to ensure its stable placement. Further explanation of when the worktable 7 stops at the appropriate position: as shown in the figure, there are four placement slots 9, meaning the worktable 7 stops rotating after each 90-degree turn. In actual production, the pause time of the worktable 7 can be adjusted reasonably according to the production cycle and equipment performance to improve production efficiency.

[0035] A drive unit 10 is mounted on the fixed frame 2 on the base 1. When the drive unit 10 is activated, its output end drives the connected turning equipment 11 to move to a suitable position to perform turning machining on the transmission box 8 placed in the placement slot 9. Simultaneously, the clamping fixture 13 mounted on the fixed frame 2 positions the transmission box 8 from above, further ensuring the stability of the transmission box 8 during turning and ensuring turning accuracy. To improve the quality of turning machining, the turning equipment 11 should be a high-precision, high-performance CNC lathe, equipped with advanced cutting tools and a cooling system. The cutting tools should be rationally selected according to the material and machining requirements of the transmission box 8. The cooling system should effectively reduce the temperature during machining, reducing tool wear and workpiece deformation; for example, cutting fluid can carry debris out and be collected through the discharge chute 24.

[0036] A motor 14 is mounted on a mounting plate 3 fixed to the base 1. When the motor 14 starts, its output drives the drive rod 22 to rotate, which in turn drives the screw 26 to rotate. Since the screw 26 is engaged with the threaded groove on the square column 17, the square column 17 begins to move when the screw 26 rotates. Two guide rails 27 are fixed on the support plate 12 on the mounting plate 3. The moving frame 16 on the moving plate 15 slidably connected to the guide rails 27 guides the square column 17, ensuring that the square column 17 can move stably.

[0037] Both the short shaft 21 and the drive rod 22 on the mounting plate 3 are fixed with transmission wheels 25, which are connected by a transmission belt 23. When the drive rod 22 rotates, it drives the short shaft 21 to rotate via the transmission belt 23. The rectangular rod 19, which is slidably connected inside the rectangular sleeve 18 on the short shaft 21, drives the transmission rod 20 to rotate, and the first bevel gear 28 on the transmission rod 20 rotates accordingly. The reciprocating screw 32, which is rotatably connected to the positioning block 33 on the square column 17, is fixed with a second bevel gear 30 on the connecting shaft 31 at the upper end. The first bevel gear 28 meshes with the second bevel gear 30, thereby driving the reciprocating screw 32 to rotate, which in turn drives the drive block 34 to reciprocate. The reciprocating movement of the drive block 34 drives the slider 36 to reciprocate. To ensure the tension of the transmission belt 23, a tensioning wheel can be set on the mounting plate 3. The position of the tensioning wheel is adjusted periodically to ensure that the transmission belt 23 is always in a good tension state, thereby improving the stability and reliability of the transmission.

[0038] The reciprocating movement of slider 36 drives the reciprocating movement of chain 41, thus enabling the reciprocating movement of all four sliders 36 and the four first laser scanners 38. During the movement of the square column 17, the sprockets 40 in its four corner mounting slots 39 rotate under the drive of chain 41. Since the sliders 36 are fixed to chain 41 and are also slidably connected to the guide rails 35 on the square column 17 via sliding sleeves 37, the four sliders 36 can move synchronously when chain 41 moves. The first laser scanners 38 mounted on the sliders 36 move along a sinusoidal path, enabling comprehensive inspection of the four inner walls of the transmission box 8 to detect any processing defects or other problems.

[0039] The slider 36 moves back and forth on the outer surface and its speed can change accordingly with the speed of the square column 17. To further explain: if the square column 17 moves fast, the speed of the reciprocating screw 32 will increase after being driven by the transmission wheel 25, transmission belt 23 and other transmissions, thereby increasing the speed of the drive block 34 to move back and forth. Conversely, if the speed decreases, the speed of the drive block 34 will decrease. This allows for comprehensive detection of the inner wall.

[0040] A movable block 43, moving synchronously with the slider 36, is provided at the end of the square column 17. An L-shaped rod 29 fixed on the movable frame 16 cooperates with a guide plate 42 inclined at the end of the square column 17. When the slider 36 moves, the movable block 43 slides on the guide plate 42, driven by the L-shaped rod 29, achieving synchronous movement with the slider 36. A second laser scanner 44 mounted on the movable block 43 inspects the rear inner wall of the transmission box 8, ensuring that all inner walls of the transmission box 8 undergo rigorous inspection. To ensure the inspection effect of the second laser scanner 44, it should be calibrated and maintained regularly to ensure its measurement accuracy and stability.

[0041] After completing the turning process and internal wall inspection, the worktable 7 rotates to the appropriate position again, such as... Figure 1 As shown, after inspection, the transmission box 8 rotates to this position so that the operator can control the robotic arm to pick up the material. The material is then unloaded from the loading port. After unloading, the worktable 7 rotates again, allowing for machining and inspection of the transmission box 8. To improve the efficiency of material handling, a high-speed, high-precision industrial robot should be selected for the robotic arm, equipped with suitable grippers, capable of quickly and accurately grasping and placing the transmission box 8. Simultaneously, safety protection devices, such as safety light curtains and guardrails, can be installed around the worktable 7 to ensure the safety of the operators.

[0042] Because the workbench 7 is designed as a circular plate and the entire device is located on the base 1, the space occupied is greatly reduced, and no subsequent handling is required, thus improving work efficiency. In actual production, the layout of the production line can be rationally planned according to the actual conditions of the production site, making full use of space and improving the utilization rate of the production site.

[0043] 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.
