Description

Technical Field

[0001] This invention belongs to the field of aluminum alloy rear swingarm manufacturing technology, specifically an intelligent integrated verification device for aluminum alloy rear swingarms. Background Technology

[0002] The rear swingarm / swing fork consists of two symmetrically arranged frame rods and a connecting rod between them. The frame rods and connecting rod form an H-shaped structure, connecting the frame and rear axle, providing support and connection. Conventional rear swingarms are made of cast iron or cast steel, with the frame rods and connecting rod welded together.

[0003] The process of integral casting of the rear horizontal fork / rear rocker arm from aluminum alloy is as follows: casting - removal of gate / riser - heat treatment; due to the relatively long overhang of the frame rod, it is easy to deform after heat treatment, resulting in deformation of the two frame rods in the Y and Z directions, causing poor subsequent processing.

[0004] Therefore, we propose an intelligent integrated verification device for aluminum alloy rear horizontal forks to solve the problems encountered above. Summary of the Invention

[0005] The purpose of this invention is to solve the problem of the aluminum alloy integrated casting process for rear swingarms / rear rocker arms: casting-removal of gates / risers-heat treatment; due to the relatively long cantilever of the frame rods, they are prone to deformation after heat treatment, resulting in deformation of the two frame rods in the Y and Z directions, causing poor subsequent processing. Therefore, an intelligent integrated verification device for aluminum alloy rear swingarms is proposed.

[0006] The objective of this invention can be achieved through the following technical solution: A worktable is included, with a slide movably mounted in the middle of the worktable. Two sets of slides are symmetrically arranged front and rear. Each set of slides has a limit mechanism inside. A second support rod is inserted into the upper end of each set of slides. A front-rear correction cylinder is located on the left end of the upper surface of the worktable. Front-rear correction blocks are located at the telescopic ends of both front-rear correction cylinders. A first support rod is inserted into the upper end of each set of front-rear correction blocks. Upper and lower correction blocks are movably mounted inside the lower ends of both front-rear correction blocks. Upper and lower correction cylinders are located at the lower ends of both upper and lower correction blocks and are located on the lower surface of the worktable. A fixing mechanism is located on the right side of the upper surface of the worktable, with three sets of fixing mechanisms. A workpiece body is fixedly mounted on the upper surface of the worktable through the fixing mechanism.

[0007] In a preferred embodiment of the present invention, the limiting mechanism includes a fastening screw, which is threadedly connected to the inside of the slide block. The inner end of the fastening screw is rotatably connected to a limiting block, and the upper end of the limiting block is provided with a positioning rod. The other end of the positioning rod is movably inserted into the inside of the slide block.

[0008] In a preferred embodiment of the present invention, a sliding groove is provided in the middle of the workbench, and two sets of sliding grooves are symmetrically arranged in front and behind. A slider is slidably installed inside the two sets of sliding grooves, and the upper surface of the two sets of sliders is connected to the lower surface of the two sets of sliding blocks respectively.

[0009] In a preferred embodiment of the present invention, the fixing mechanism includes a lever cylinder and a support block, and both the lever cylinder and the support block are disposed on the upper surface of the workbench. A pressure plate is hinged to the upper end of the lever cylinder. The side of the pressure plate near the lever cylinder is rotatably mounted on the lever cylinder through a fulcrum. A pressure block is hinged to the end of the pressure plate away from the lever cylinder, and the pressure block is disposed above the support block.

[0010] In a preferred embodiment of the present invention, a limiting guide plate is provided on the left side of the upper surface of the worktable, and two sets of limiting guide plates are symmetrically arranged in front and back. Each set of limiting guide plates has two sets of limiting guide plates symmetrically arranged in the left and right. The two sets of front and rear correction blocks are slidably installed on the worktable through the two sets of limiting guide plates.

[0011] In a preferred embodiment of the present invention, a base is provided on the left end of the upper surface of the workbench, and two sets of bases are symmetrically arranged in front and behind. A pin is provided inside the upper end of each set of bases, and a detection block is provided on the right end of each set of pins. The right ends of the two detection blocks are respectively located inside the two upper and lower calibration blocks.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0013] (1) By setting up upper and lower correction cylinders, support rod one and upper and lower correction blocks, the workpiece can be accurately corrected in the Z direction. By setting up front and rear correction cylinders, front and rear correction blocks and support rod two, the workpiece can be accurately corrected in the Y direction. The operation is simple and quick, and the calibration and inspection are integrated with a high pass rate.

[0014] (2) The three sets of fixing mechanisms can stably fix the workpiece on the worktable, preventing the workpiece from moving during the correction process, thereby improving the correction efficiency and correction quality.

[0015] (3) By controlling the correction displacement, cylinder speed and holding time through the analysis module, the pass rate of the first correction is improved, which facilitates the operation of workers and avoids the ineffective control of parameters. Relying on the worker's experience to operate the cylinder control valve, the correction is not completed in one time and repeated correction is required, which is inefficient and labor-intensive. It also avoids over-correction that causes cracks and breaks in the workpiece, resulting in scrap. It reduces scrap loss, effectively improves the quality and efficiency of correction, and reduces the cost of correction. Attached Figure Description

[0024] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. 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.

[0025] Example

[0026] Please see Figure 1 - Figure 6As shown, an intelligent integrated calibration device for an aluminum alloy rear flat fork includes a workbench 1. A slide 6 is movably installed in the middle of the workbench 1, and two sets of slides 6 are symmetrically arranged in front and behind. Each set of slides 6 has a limit mechanism 5 inside. A support rod 4 is inserted into the upper end of each set of slides 6. A front and rear correction cylinder 9 is provided on the left end of the upper surface of the workbench 1. A front and rear correction block 14 is provided at the telescopic end of each of the two front and rear correction cylinders 9. A support rod 3 is inserted into the upper end of each of the two sets of front and rear correction blocks 14. An upper and lower correction block 11 is movably installed in the lower end of each of the two upper and lower correction blocks 14. An upper and lower correction cylinder 7 is provided at the lower end of each of the two upper and lower correction blocks 11. The upper and lower correction cylinder 7 is located on the lower surface of the workbench 1. A fixing mechanism 8 is provided on the right side of the upper surface of the workbench 1, and three sets of fixing mechanisms 8 are provided. The workpiece body 2 is fixedly installed on the upper surface of the workbench 1 through the fixing mechanism 8.

[0027] It should be noted that when the workpiece body 2 needs to be placed on the worktable 1, the support rod 1 3 and support rod 2 4 need to be removed from the front and rear correction blocks 14 and the slide block 6 respectively. Only then can the workpiece body 2 be placed on the worktable 1. The upper and lower correction blocks 11 are slidably mounted on the upper and lower correction cylinders 7. That is, when the front and rear correction cylinders 9 drive the front and rear correction blocks 14 to move horizontally back and forth, they will also drive the upper and lower correction blocks 11 to move horizontally back and forth, avoiding jamming and allowing the Y-axis correction of the workpiece body 2 to proceed smoothly. The length of the slot opened on the front and rear correction blocks 14 is greater than the diameter of the support rod 1 3, so that the upper and lower correction cylinders 7 can drive the upper and lower correction blocks 11 and the support rod 1 3 to move smoothly in the vertical direction.

[0028] The limiting mechanism 5 includes a fastening screw 501, which is threadedly connected to the inside of the slide block 6. The inner end of the fastening screw 501 is rotatably connected to a limiting block 502, so that when the fastening screw 501 rotates, it will not drive the limiting block 502 to rotate, and thus can smoothly drive the limiting block 502 to move back and forth horizontally. The upper end of the limiting block 502 is provided with a positioning rod 503, and the other end of the positioning rod 503 is movably inserted into the inside of the slide block 6. The positioning rod 503 can limit the limiting block 502, preventing the fastening screw 501 from rotating and driving the limiting block 502 to rotate, while not affecting the back and forth horizontal movement of the limiting block 502. The slide block 6 has a positioning groove inside that matches the positioning rod 503, providing the positioning rod 503 with room to move, so that the positioning rod 503 can move back and forth horizontally stably.

[0029] The worktable 1 has a slide groove 13 in the middle, and two sets of slide grooves 13 are symmetrically arranged in front and behind. Slider 12 is slidably installed inside the two sets of slide grooves 13. The upper surface of the two sets of slider 12 is connected to the lower surface of the two sets of slide blocks 6 respectively. The slide groove 13 provides the slider 12 with room to move. The slider 12 allows the slide block 6 to move smoothly left and right horizontally, and then move to any position in the middle of the workpiece body 2, thereby limiting and fixing the workpiece body 2, which is convenient for subsequent correction of the workpiece body 2.

[0030] The fixing mechanism 8 includes a lever cylinder 801 and a support block 802, and both the lever cylinder 801 and the support block 802 are set on the upper surface of the worktable 1. The upper end of the lever cylinder 801 is hinged to a pressure plate 803. The side of the pressure plate 803 near the lever cylinder 801 is rotatably mounted on the lever cylinder 801 through a fulcrum. The setting of the fulcrum allows the pressure plate 803 to rotate around the fulcrum. When the lever cylinder 801 drives the connecting end of the pressure plate 803 to rotate upward, the other end of the pressure plate 803 will rotate downward. Similarly, when the lever cylinder 801 drives the connecting end of the pressure plate 803 to rotate downward, the other end of the pressure plate 803 will rotate upward. This facilitates the placement of the workpiece body 2 into or from the fixing mechanism 8. The end of the pressure plate 803 away from the lever cylinder 801 is hinged to a pressure block 804, and the pressure block 804 is set above the support block 802.

[0031] It should be noted that two sets of fixing mechanisms 8 are respectively located on the right side of the two sets of slides 6, and another set of fixing mechanisms 8 is located at the far right end of the middle of the upper surface of the worktable 1, so that the three sets of fixing mechanisms 8 are distributed in a triangle. This makes the workpiece more stable when it is fixed, and avoids the workpiece from moving and affecting the calibration work. The upper surface of the support block 802 is provided with a V-shaped groove. The design of the V-shaped groove allows the support block 802 to better adapt to the shape of the round workpiece, providing stable support and positioning, ensuring that the workpiece will not slide or move during the clamping process, thereby improving the stability during calibration.

[0032] A limiting guide plate 17 is provided on the left side of the upper surface of the workbench 1, and two sets of limiting guide plates 17 are symmetrically arranged in front and back. Each set of limiting guide plates 17 has two sets of limiting guide plates 17 symmetrically arranged in the left and right. The two sets of front and rear correction blocks 14 are slidably installed on the workbench 1 through the two sets of limiting guide plates 17. The setting of the limiting guide plate 17 can limit the front and rear correction blocks 14, so as not to affect the horizontal movement of the front and rear correction blocks 14, and enable the front and rear correction blocks 14 to move horizontally back and forth stably.

[0033] A base 15 is provided on the left end of the upper surface of the workbench 1, and two sets of bases 15 are symmetrically arranged front and back. The upper end of each set of bases 15 is provided with a pin 16, and the right end of each set of pins 16 is provided with a detection block 10. The right ends of the two detection blocks 10 are respectively located inside the two upper and lower correction blocks 11. The pins 16 can quickly assemble and disassemble the detection blocks 10, thereby quickly detecting the workpiece deformation data and providing data for subsequent correction work. The detection block 10 is provided with a CAE analysis module, which is an empirical formula derived from the correction analysis of the rear flat fork. The workpiece body 2 is analyzed through the detection block 10, and the support point of the integrated calibration device is determined according to the analysis results. The cross-sectional shape of the support rod and the magnitude of the calibration pressure are determined by the support point position, the support rod, and the physical setting to ensure that the workpiece will not break during calibration. Since the CAE analysis module is existing technology, it will not be described in detail.

[0034] When using this invention, firstly, three sets of lever cylinders 801 are activated, causing the lever cylinders 801 to drive the pressure block 804 away from the support block 802. At this time, the workpiece body 2 can be placed on the upper surface of the worktable 1. Then, the three sets of lever cylinders 801 are activated, causing the three sets of lever cylinders 801 to drive the pressure plate 803 to rotate, so that the pressure plate 803 is in a horizontal state. Then, the workpiece body 2 is fixed on the worktable 1 through the cooperation of the pressure block 804 and the support block 802. Then, two support rods 1 3 are respectively inserted into two sets of front and rear correction blocks 14, and two support rods 2 4 are respectively inserted into two sets of slide blocks 6. Then, the CAE analysis module is used to analyze the correction data of the workpiece body 2.

[0035] Then, based on the analysis data, the two sets of slide blocks 6 are moved horizontally so that the two sets of slide blocks 6 are moved to the right side of the bending part of the workpiece body 2. Then, the fastening screws 501 inside the two sets of slide blocks 6 are rotated. The rotation of the fastening screws 501 drives the limiting block 502 to move closer to the workpiece body 2, thereby clamping and fixing the workpiece body 2, so that the slide blocks 6 are connected to the workpiece body 2.

[0036] At this point, the two sets of front and rear correction cylinders 9 are activated. The two sets of front and rear correction cylinders 9 drive the two sets of front and rear correction blocks 14 to move horizontally back and forth, thereby correcting the workpiece in the Y direction. When the workpiece moves to the position of the set stroke of the cylinder under the set load and displacement speed, the pressure is held for the set time, the cylinder load is removed, the workpiece support rod returns to the corrected position, and the detection block 10 is pushed to detect whether the workpiece is within the allowable deformation tolerance. For individual workpieces that cannot be corrected successfully in one attempt, the correction and detection operation is repeated until the workpiece is within the allowable deformation tolerance, thus completing the Y-direction correction.

[0037] Then, the upper and lower correction cylinders 7 are activated. The upper and lower correction cylinders 7 drive the upper and lower correction blocks 11 to move vertically, thereby correcting the workpiece in the Z direction. When the workpiece moves to the position of the set stroke of the upper and lower correction cylinders 7 under the set load and displacement speed, the pressure is held for the set time, the cylinder load is removed, the workpiece support rod returns to the corrected position, and the detection block 10 is pushed to check whether the workpiece is within the allowable deformation tolerance. For individual workpieces that cannot be corrected successfully on the first try, the correction and detection operation is repeated until the workpiece is within the allowable deformation tolerance, thus completing the Z-direction correction.

Clearly, many modifications and variations can be made based on the content of this specification.
