Description

Technical Field

[0001] This application relates to the field of machining technology, and in particular to a machining apparatus for a rotating body tooling. Background Technology

[0002] As a core component of a car engine, the flywheel plays a role in storing kinetic energy, balancing the crankshaft, and transmitting torque during power transmission. Its side usually needs to be machined with high-precision sensing holes (such as positioning pin holes, weight reduction holes, etc.) to install sensors or achieve dynamic balance. Since the flywheel is a rotating structure, traditional machining equipment is mostly a combination of indexing plate and independent drilling unit, which requires multiple adjustments to the tooling posture, resulting in low machining efficiency.

[0028] Please see Figures 1 to 6 This application exemplarily provides a machining apparatus for a rotating body tooling, comprising:

[0029] Base 1;

[0030] A rotating stage 2 is set on a base 1. A base plate 6 for placing a workpiece 3 is set on the rotating stage 2. The rotating stage 2 can drive the base plate 6 to rotate around its own center line. A positioning mandrel 16 is set on the base plate 6 for positioning and mounting the workpiece 3 on the base plate 6.

[0031] At least three processing mechanisms are set on the base 1 and evenly distributed around the circumference of the rotating table 2. The processing mechanisms are used to drill holes in the workpiece 3. The processing mechanisms can move horizontally to approach or move away from the workpiece 3. The processing mechanisms can move vertically to be level with the working processing position in height.

[0032] In the machining apparatus for rotary tooling provided in this application, the workpiece 3 is placed on the base plate 6, and the positioning mandrel 16 positions and installs the workpiece 3 on the base plate 6. The three machining mechanisms are distributed along the circumferential direction of the workpiece 3, which can simultaneously perform drilling machining on three positions of the workpiece 3. By rotating the rotary table 2 to drive the base plate 6 to rotate, the workpiece 3 can be rotated, thereby changing the machining position. This allows the machining mechanisms to perform drilling machining on different angle positions of the workpiece 3. The simultaneous machining of the three machining mechanisms effectively improves the drilling machining efficiency.

[0033] It should be noted that, in this embodiment, as Figure 2 As shown, workpiece 3 is a flywheel. The flywheel is disc-shaped. A positioning hole 11 for cooperating with the positioning mandrel 16 is provided in the middle of the flywheel. Multiple limiting holes 12 are provided around the positioning hole 11. The diameter of the upper half 13 of the flywheel is larger than the diameter of the lower half 14. The side of the upper half 13 of the flywheel is the drilling position. The lower half 14 of the flywheel has a support surface 15.

[0034] In some embodiments, the substrate 6 is further provided with a first limiting pin 18 and a leveling block 17. The first limiting pin 18 is disposed circumferentially on the positioning mandrel 16 and is used to extend into the limiting hole 12 of the workpiece 3 to limit the workpiece 3. Multiple leveling blocks 17 are provided, and the multiple leveling blocks 17 are evenly distributed circumferentially on the substrate 6 to support the workpiece 3 and keep it horizontal. Specifically, the leveling blocks 17 are distributed circumferentially on the substrate 6, and the lines connecting the leveling blocks 17 can form multiple circles of different sizes on the substrate 6. The leveling blocks 17 are detachably mounted on the substrate 6. For workpieces 3 of different sizes, due to the different sizes of the workpieces 3... Workpieces 3 have different heights, diameters, and shapes. By replacing the leveling blocks 17 with different heights, the leveling blocks 17 form circles of different sizes according to the diameter of the workpiece 3. The leveling blocks 17 are in close contact with the support surface 15 of the lower half 14 of the workpiece 3 to support the workpiece 3 and keep it horizontal after installation. This can achieve the support and positioning of workpieces 3 of different specifications. At the same time, the height of the leveling blocks 17 can be set according to the height of the workpiece 3. The leveling blocks 17 raise the workpiece 3 so that the processing position on the side of the workpiece 3 can be kept at the same horizontal height as the processing mechanism. The workpiece 3 can be kept horizontal, which is convenient for drilling.

[0035] In this embodiment, the processing device for the rotary tooling further includes a positioning support mechanism, which is mounted on the base 1. The positioning support mechanism includes a support frame 7 and a positioning block 8. The support frame 7 is located on one side of the rotating table 2. Movable slots 31 are provided on both sides of the support frame 7. The positioning block 8 is mounted on the movable slot 31 and can move on the movable slot 31. Specifically, the support frame 7 has a U-shaped structure. Parallel support beams 9 are provided above the support frame 7. The movable slots 31 are provided on the support beams 9. There are four movable slots 31, which are arranged in pairs opposite to each other on the two support beams. On beam 9, two positioning blocks 8 on the same supporting beam 9 are connected by a drive plate 23. By pushing the drive plate 23, the opposing positioning blocks 8 are brought closer to each other to position the workpiece 3 between the supporting beams 9. When the positioning blocks 8 are installed on the supporting beam 9 through the movable groove 31, the positioning blocks 8 and the supporting beam 9 are perpendicular to each other. For workpieces 3 of different diameters, by moving the positioning blocks 8 on the movable groove 31, the bottom surface of the upper half 13 of the workpiece 3 contacts the positioning blocks 8, and the positioning blocks 8 abut against the side of the lower half 14 of the workpiece 3 to position the workpiece 3 between the supporting beams 9.

[0036] In some embodiments, the machining device for the rotary tooling further includes a lifting support mechanism, which is mounted on the base 1. The lifting support mechanism includes a support seat 24, a lifting plate 25, and a positioning plate 26. The support seats 24 are arranged opposite each other on both sides of the rotary table 2. The positioning support mechanism is adjacent to any of the support seats 24. A drive cylinder 27 and a guide rod 28 are provided on the support seat 24. The lifting plate 25 is movably mounted on the guide rod 28. The drive cylinder 27 is used to drive the lifting plate 25 to move vertically on the guide rod 28. At least two positioning plates 26 are provided. The two ends of the positioning plates 26 rest on the lifting plate 25 and can be connected by mounting blocks 29. The workpiece 3 is detachably installed on the lifting plate 25 and positioned on the support frame 7 by the positioning block 8. The alignment of the positioning plate 26 with the positioning block 8 is adjusted, and the workpiece 3 is pushed from the support frame 7 into the space between the positioning plates 26. Specifically, after the positioning block 8 positions the positioning part, the lifting plate 25 is driven by the driving cylinder 27 to move on the guide rod 28 so that the height of the positioning plate 26 is the same as the height of the positioning block 8 and is aligned with the positioning block 8. By the detachable mounting block 29, the distance between the positioning plates 26 can be adjusted so that the distance between the positioning plates 26 is the same as the distance between the positioning blocks 8, and the workpiece 3 is pushed from the space between the positioning blocks 8 into the space between the positioning plates 26.

[0037] In detail, each positioning plate 26 is provided with a limiting plate 30 for limiting the workpiece 3 in the pushing direction of the workpiece 3. The limiting plate 30 has a triangular structure and is fixed to the positioning plate 26. When adjusting the positioning plate 26, the limiting plate 30 moves with the positioning plate 26. After the workpiece 3 is pushed from between the positioning blocks 8 into between the positioning plates 26, until the workpiece 3 is blocked by the limiting plate 30, the limiting plate 30 contacts the workpiece 3, and the pushing of the workpiece 3 stops. The driving cylinder 27 lowers the lifting plate 25, and the positioning plate 26 follows suit. The workpiece descends synchronously, causing the positioning hole 11 of the workpiece 3 to engage with the positioning mandrel 16, and the workpiece 3 to come into contact with the leveling block 17, thereby positioning and installing the workpiece 3 on the base plate 6. Since the workpiece 3 is positioned at the top, the workpiece 3 is pushed between the positioning plates 26, and the limiting plate 30 limits the workpiece 3 in the pushing direction. When replacing the leveling block 17, the leveling block 17 of appropriate height can be installed or removed according to the diameter of the workpiece 3 above, which makes it easy to select the installation position of the leveling block 17 on the base plate 6, so that the circle formed by the leveling block 17 matches the diameter of the workpiece 3.

[0038] In this embodiment, a clearance position is provided in the middle of the substrate 6 along the circumference of the positioning mandrel 16. A cover plate 19 is provided on the clearance position to cover it. The cover plate 19 is movably inserted through the positioning mandrel 16 and the first limiting pin 18. Specifically, since the specifications of the workpieces 3 are different, some specifications of the workpieces 3 are taller. After installation, the processing position on the side of the workpiece 3 is higher than the maximum height of the processing mechanism. In order to ensure the accuracy of the processing position, the lower half 14 of the workpiece 3 can be at least partially inserted into the clearance position by removing the cover plate 19. This can meet the processing requirements of the taller workpieces 3 and ensure that the processing position on the side of the workpiece 3 is not higher than the maximum height of the processing mechanism, thus meeting the processing requirements of more specifications of workpieces 3. When the clearance position is not needed to avoid the workpiece 3, the cover plate 19 can be placed on the clearance position to fill it.

[0039] In the above embodiment, a pad 20 is also provided on the cover plate 19. The pad 20 is movably inserted through the positioning spindle 16 and the first limiting pin 18. The positioning spindle 16 and the first limiting pin 18 extend at least partially from the top surface of the pad 20. Specifically, due to the different specifications of the workpieces 3, for workpieces 3 with smaller heights, after installation, the processing position on the side of the workpiece 3 is lower than the minimum height of the processing mechanism. In order to ensure the accuracy of the processing position, by inserting the pad 20 through the positioning spindle 16 and the first limiting pin 18, the lower half 14 of the workpiece 3 contacts the pad 20, and the pad 20 raises the workpiece 3 so that the processing position on the side of the workpiece 3 will not be lower than the minimum height of the processing mechanism, which can meet the processing needs of more specifications of workpieces 3.

[0040] In some embodiments, the pad 20 is also provided with an installation port, and an installation plate 21 is provided on the installation port. The installation plate 21 is provided with a second limiting pin 22. For workpieces 3 with smaller height, the diameter of the lower half 14 gradually narrows, and the position of the limiting hole 12 is also different. The first limiting pin 18 cannot cooperate with the limiting hole 12 of the workpiece 3. When installing workpieces 3 with smaller diameter of the lower half 14, a second limiting pin 22 is added to the pad 20. The second limiting pin 22 cooperates with the limiting hole 12 of the workpiece 3. The second limiting pin 22 extends into the limiting hole 12 of the workpiece 3, so that the installed workpiece 3 will not rotate.

[0041] In this embodiment, the processing mechanism includes a base 4 and a processing head 5. The front end of the processing head 5 has a drill bit 10 for drilling. The processing head 5 can move horizontally on the base 4 to move the drill bit 10 closer to or away from the workpiece 3. The processing head 5 can also move vertically on the base 4 to move the drill bit 10 up and down. Specifically, the three processing mechanisms are evenly distributed around the circumference of the rotating table 2, forming a 120° distribution. A motor for driving the processing head 5 is provided on the base 4. The motor drives the processing head 5 to move, causing the drill bit 10 to move up and down. The rotating table 2 is an MRS precision electronically controlled rotating table with C-axis indexing, which can achieve 360° full closed-loop control with a minimum index of 0.001°. Traditional processing equipment requires a 360° rotation to complete the drilling of the workpiece 3 in a full circle. The rotating table 2 of this application only needs to rotate 120°. The three processing mechanisms perform drilling simultaneously, which greatly improves the drilling efficiency. The three processing mechanisms are controlled by PLC, which can control the three processing mechanisms to perform drilling simultaneously or separately according to the processing requirements.

[0042] It is worth noting that the machining device for the rotary tooling also includes a clamping mechanism (not shown in the figure). Specifically, in one embodiment, the clamping mechanism can be configured as a hydraulic cylinder. When the workpiece 3 is being drilled, the hydraulic cylinder presses the workpiece 3 onto the base plate 6, reducing the slight displacement of the workpiece 3 during the machining process and improving the machining accuracy. In another embodiment, the clamping mechanism can be configured as a mechanical jaw. When the workpiece 3 is being drilled, the mechanical jaw clamps the workpiece 3, reducing the slight displacement of the workpiece 3 during the machining process and improving the machining accuracy.

[0043] In summary, in the machining apparatus for rotary tooling provided in this application, by placing the workpiece 3 on the base plate 6 and positioning the workpiece 3 on the base plate 6 with the positioning mandrel 16, and distributing the three machining mechanisms along the circumferential direction of the workpiece 3, drilling can be performed on three positions of the workpiece 3 simultaneously. By rotating the rotary table 2 to drive the base plate 6 to rotate, the workpiece 3 can be rotated, thereby changing the machining position. This allows the machining mechanisms to perform drilling on different angle positions of the workpiece 3. The simultaneous processing by the three machining mechanisms effectively improves the drilling efficiency.

[0044] The above embodiments are merely illustrative of the principles and effects of this application and are not intended to limit this application. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this application. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this application should still be covered by the claims of this application.
