DETAILED DESCRIPTION

[0024] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] Example

[0026] See also Figure 1 - Figure 6As shown, an integrated intelligent calibration device for an aluminum alloy rear flat fork comprises a workbench 1, a slide seat 6 is movably installed in the middle of the workbench 1, and two groups of slide seats 6 are symmetrically arranged front and back, and the interiors of the two groups of slide seats 6 are both provided with a limiting mechanism 5, and the upper ends of the two groups of slide seats 6 are both plugged with a support rod 2 4, and the left end of the upper surface of the workbench 1 is provided with a front and rear correction cylinder 9, and the telescopic ends of the two front and rear correction cylinders 9 are both provided with a front and rear correction block 14, and the upper ends of the two groups of front and rear correction blocks 14 are both plugged with a support rod 1 3, and the lower ends of the two front and rear correction blocks 14 are both movably installed with an upper and lower correction block 11, and the lower ends of the two upper and lower correction blocks 11 are both provided with an upper and lower correction cylinder 7, and the upper and lower correction cylinder 7 is arranged on the lower surface of the workbench 1, and a fixing mechanism 8 is arranged on the right side of the upper surface of the workbench 1, and the fixing mechanism 8 is provided with three groups, and the upper surface of the workbench 1 is fixedly installed with a workpiece body 2 through the fixing mechanism 8;

[0027] It should be noted that when the workpiece body 2 needs to be placed on the workbench 1, it is necessary to first take out the support rod 1 3 and the support rod 2 4 from the inside of the front and rear correction blocks 14 and the slide 6 respectively. Only then can the workpiece body 2 be placed on the workbench 1, wherein the upper and lower correction blocks 11 are slidably installed 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 to avoid jamming, so that the Y-direction correction work of the workpiece body 2 can be carried out smoothly, wherein the length of the slots 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 3 to move vertically smoothly.

[0028] The limiting mechanism 5 includes a fastening screw 501, which is threadedly connected to the inside of the sliding seat 6. The inner end of the fastening screw 501 is rotatably connected to the limiting block 502, so that when the fastening screw 501 rotates, it will not drive the limiting block 502 to rotate, and then it can smoothly drive the limiting block 502 to move horizontally forward and backward. A positioning rod 503 is arranged inside the upper end of the limiting block 502, and the other end of the positioning rod 503 is movably inserted into the inside of the sliding seat 6. The setting of the positioning rod 503 can limit the limiting block 502 to prevent the fastening screw 501 from rotating and driving the limiting block 502 to rotate, and at the same time does not affect the horizontal movement of the limiting block 502 forward and backward. A positioning groove matching the positioning rod 503 is opened inside the sliding seat 6 to provide a movable space for the positioning rod 503, so that the positioning rod 503 can stably move horizontally forward and backward.

[0029] A slide groove 13 is provided in the middle of the workbench 1, and two groups of slide grooves 13 are symmetrically arranged front and back. Slide blocks 12 are slidably installed inside the two groups of slide grooves 13. The upper surfaces of the two groups of slide blocks 12 are respectively connected to the lower surfaces of the two groups of slide seats 6. The setting of the slide groove 13 provides a movable space for the slide block 12. The setting of the slide block 12 enables the slide seat 6 to smoothly move horizontally left and right, 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 the subsequent correction of the workpiece body 2;

[0030] The fixing mechanism 8 includes a lever cylinder 801 and a support block 802, and the lever cylinder 801 and the support block 802 are both arranged on the upper surface of the workbench 1, and a pressure plate 803 is hingedly connected to the upper end of the lever cylinder 801, and the side of the pressure plate 803 close to the lever cylinder 801 is rotatably mounted on the lever cylinder 801 through a fulcrum. The setting of the fulcrum enables the pressure plate 803 to rotate around the fulcrum as the center of the circle, and then 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, and then it is convenient for the workpiece body 2 to be placed in the fixing mechanism 8 or taken out from the fixing mechanism 8. The end of the pressure plate 803 away from the lever cylinder 801 is hingedly connected to a pressure block 804, and the pressure block 804 is arranged above the support block 802;

[0031] It should be noted that two groups of fixing mechanisms 8 are respectively arranged on the right side of the two groups of slides 6, and the other group of fixing mechanisms 8 is arranged at the rightmost end in the middle of the upper surface of the workbench 1, so that the three groups of fixing mechanisms 8 are distributed in a triangular shape, which makes it more stable when fixing the workpiece, and avoids the movement of the workpiece to affect the correction work. Among them, a V-shaped groove is opened on the upper surface of the support block 802. The design of the V-shaped groove enables the support block 802 to better adapt to the shape of the circular workpiece, provide stable support and positioning, and ensure that the workpiece will not slide or move during the clamping process, thereby improving the stability during correction.

[0032] A limiting guide plate 17 is provided on the left side of the upper surface of the workbench 1, and two groups of limiting guide plates 17 are symmetrically provided front and back, and each group of limiting guide plates 17 is symmetrically provided with two groups. The two groups of front and rear correction blocks 14 are respectively slidably installed on the workbench 1 through the two groups 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, so that the front and rear correction blocks 14 can stably perform front and rear horizontal movement;

[0033] A base 15 is provided at the left end of the upper surface of the workbench 1, and two groups of bases 15 are symmetrically provided front and back. Pins 16 are provided inside the upper ends of the two groups of bases 15, and detection blocks 10 are provided at the right ends of the two groups of pins 16. The right ends of the two detection blocks 10 are respectively arranged inside the two upper and lower correction blocks 11. The setting of the pin 16 can quickly disassemble and assemble the detection block 10, and then can quickly detect the deformation data of the workpiece to provide data for subsequent correction work. A CAE analysis module is provided inside the detection block 10, that is, an empirical formula obtained 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 result. The cross-sectional shape of the support point position rack and the size of the physical calibration pressure are used to ensure that the workpiece will not break during calibration. Since the CAE analysis module is a prior art, it will not be described in detail.

[0034] When the present invention is in use, firstly, the three groups of lever cylinders 801 are started, so that the lever cylinders 801 drive the pressure block 804 away from the support block 802, and at this time, the workpiece body 2 can be placed on the upper surface of the workbench 1, and then the three groups of lever cylinders 801 are started, and the three groups of lever cylinders 801 drive the pressure plate 803 to rotate, so that the pressure plate 803 is in a horizontal state, and then the workpiece body 2 is fixed on the workbench 1 through the cooperation of the pressure block 804 and the support block 802, and then the two support rods 1 3 are respectively plugged into the two groups of front and rear correction blocks 14, and the two groups of support rods 2 4 are respectively plugged into the two groups of slide seats 6, and then the CAE analysis module is used to analyze the correction data of the workpiece body 2;

[0035] Then, according to the analysis data, the two sets of slides 6 are horizontally moved to the right side of the bending part of the workpiece body 2, and then the fastening screws 501 inside the two sets of slides 6 are rotated, and the fastening screws 501 rotate to drive the limit blocks 502 to approach the workpiece body 2, thereby clamping and fixing the workpiece body 2, so that the slides 6 are connected to the workpiece body 2;

[0036] At this time, the two groups of front and rear correction cylinders 9 are started again, and the two groups of front and rear correction cylinders 9 drive the two groups of front and rear correction blocks 14 to move horizontally forward and backward, so as to correct the workpiece in the Y direction. At the set load and displacement speed, the workpiece moves to the position of the cylinder set stroke, and the pressure is maintained for the set time. The cylinder load is removed, and the workpiece rack returns to the position after correction. The detection block 10 is pushed to detect whether the workpiece is within the tolerance of the allowable deformation. For individual workpieces that cannot be corrected once, the correction and detection operation is repeated until the workpiece is within the tolerance of the allowable deformation, and the Y correction is completed;

[0037] Then start the upper and lower correction cylinders 7, which drive the upper and lower correction blocks 11 to move in the vertical direction, so as to perform Z-direction correction on the workpiece. Under the set load and displacement speed, the workpiece moves to the position of the set stroke of the upper and lower correction cylinders 7, and the pressure is maintained for the set time. The cylinder load is removed, and the workpiece rack returns to the position after correction. 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 time, the correction and detection operation is repeated until the workpiece is within the allowable deformation tolerance, and the Z-direction correction is completed.
