Abstract
Description
Technical Field
[0001] This invention relates to the field of side leg support processing technology, specifically a tooling mechanism for processing a combined ultra-long side leg support. Background Technology
[0002] The machining of large parts needs to be carried out on a bridge-type gantry five-axis machining center. The side leg support of the bridge-type gantry five-axis machining center is an important part of the machine tool and a key load-bearing component. For the machining of large parts, an extra-long bridge-type gantry five-axis machining center is required, which undoubtedly requires an extra-long side leg support. However, due to the limitations of blank manufacturing, processing equipment, and transportation, it is difficult to make the side leg support part reach a very long size. The actual practice is usually to disassemble the extra-long bridge-type gantry five-axis machining center side leg support and then connect them.
[0003] The existing docking method involves precision machining of the multiple side leg brackets that need to be docked. The end faces of each side leg bracket contact and fit together, and bolts are used to connect the end faces. After the connection is fixed, flush-joint pins are driven into the docking gaps to obtain and maintain a certain level of accuracy. However, this brings problems: the mounting surfaces and end faces of the linear guides, grating rulers, racks, etc. of each side leg bracket to be docked require precision machining, which has very high requirements. After precision machining, some side leg brackets even need to be scraped by a fitter during docking to achieve the accuracy requirements of straightness and perpendicularity. For the back surface of the linear guide on the side leg bracket, scraping is quite difficult and almost impossible. Summary of the Invention

[0035] 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.
[0036] Example 1: Please refer to Figures 1 to 8 The present invention provides a technical solution: a tooling mechanism for processing a combined ultra-long side leg bracket, including a side leg bracket 1 and a tooling base 11. A first through groove 12 and a second through groove 13 are respectively opened on the side leg bracket 1 and the tooling base 11. Positioning keyways 2 are opened on both sides of the mating surface of the side leg bracket 1 and the tooling base 11, and key rods 21 are provided in the positioning keyways 2.
[0037] A first guide post 3 is fixedly installed on the mating surface of the tooling base 11. A first reset spring 31 is sleeved on the outer periphery of the first guide post 3. A first follower 32 is movably installed on the outer surface of the first guide post 3. Claws 33 are fixedly installed on both sides of the mating surface of the side leg bracket 1. A slot 34 is opened on the first follower 32.
[0038] Both sides of the mating surface of the side leg bracket 1 are rotatably connected to the limit claw 4 by a torsion spring, and the key rod 21 has a limit groove 41.
[0039] It also includes a fastening assembly, which includes a second guide post 5 fixedly installed inside the tooling base 11, and a second return spring 51 sleeved on the outer periphery of the second guide post 5. A second follower 52 is movably installed on the outer surface of the second guide post 5.
[0040] The first driving member 53 is movably mounted on both sides of the second driven member 52. The first driving member 53 is fixedly mounted on the first rack 54. One side of the first rack 54 is meshed with a gear 55, and the other side of the gear 55 is meshed with a second rack 56. The second rack 56 is fixedly mounted with a fastener 57.
[0041] A slider 6 is fixedly installed on both the first rack 54 and the second rack 56. A mounting bracket 61 is fixedly installed on both sides inside the tooling base 11. The mounting bracket 61 has a groove inside that matches the slider 6. The slider 6 is movably installed with the mounting bracket 61 to guide and limit the first rack 54 and the second rack 56.
[0042] The four corners of the side leg bracket 1 and the tooling base 11 are provided with screw holes 7, and bolts 71 are threaded into the screw holes 7.
[0043] Specifically, during segmented processing, the chuck 33 is first fixed to the mating surface of the side leg bracket 1 with screws. Then, the side leg bracket 1 and the tooling base 11 are aligned through the positioning keyway 2, ensuring precise docking. Next, two key rods 21 are inserted into the positioning keyway 2. The key rods 21 support the tooling base 11, preventing it from falling or shifting after docking, and also enhance bending and torsional resistance during processing, improving positioning accuracy. When the key rods 21 are inserted into the positioning keyway 2, they drive the first driven member 32, causing it to move upwards. When the first driven member 32 moves upward, the pawl 33 contacts the slot 34. Under the constraint of the slot 34, the pawl 33 retracts inward and enters the slot 34. When the key rod 21 is fully inserted into the positioning keyway 2, the first driven member 32 rises to its highest position. At this time, the pawl 33 will pass over the slot 34 to the bottom of the first driven member 32, and the pawls on both sides of the pawl 33 are no longer constrained by the slot 34, thus resetting. The pawl 33 and the first driven member 32 can be used to initially fix the side leg bracket 1 and the tooling base 11, further preventing the side leg bracket 1 and the tooling base 11 from shifting after alignment, as shown in the attached instruction manual. Figure 3 Included with instruction manual Figure 6 As shown; when the first driven member 32 rises, it also drives one end of the limiting claw 4, causing the other end of the limiting claw 4 to move downward and enter the limiting groove 41, thus limiting the key rod 21 and preventing the key rod 21 from disengaging from the joint between the side leg bracket 1 and the tooling base 11, as shown in the attached manual. Figure 13 As shown;
[0044] Furthermore, before assembling the side leg bracket 1 and the tooling base 11, 37 needs to be fixed to the second rack 56 with screws. After the side leg bracket 1 and the tooling base 11 are aligned, 37 will enter the inner side of the side leg bracket 1 through the second through slot 13 and the first through slot 12. Since the connecting member 58 fixes the first driven member 32 and the second driven member 52 together, when the first driven member 32 moves upward, the second driven member 52 will also move upward. The tooling base 11 also has a drive slot 59 adapted to the connecting member 58. When the second driven member 32 moves upward... When the driven member 52 moves upward, it drives the first driving member 53, which in turn drives the first rack 54. The first rack 54 drives the gear 55 to rotate, which in turn drives the second rack 56. This causes the second rack 56 to move the fastener 57. One side of the fastener 57 is inclined, and when the fastener 57 moves, it presses against the side leg bracket 1, making the side leg bracket 1 and the tooling base 11 more tightly fitted, reducing the probability of misalignment and improving machining accuracy, as shown in the attached manual. Figure 9 —Instruction manual included Figure 11 As shown;
[0045] Furthermore, after the side leg bracket 1 and the tooling base 11 are connected, the bolt 71 is screwed into the screw hole 7, thereby locking the side leg bracket 1 and the tooling base 11, and fully completing the fixation of the side leg bracket 1 and the tooling base 11.
[0046] Example 2: Please refer to Figures 9 to 12 The upper surfaces of the tooling base 11 and the side leg bracket 1 are provided with a tool setting surface 8 and a machining surface 81, and the upper surface of the tooling base 11 is provided with a multi-faceted inspection tool 82.
[0047] It also includes a slide rail assembly, which includes 83 fixedly installed on both sides of the multi-faceted gauge 82, 84 provided on the tooling base 11, and 87 fixedly installed at both ends of 84, and 86 provided at both ends of the key rod 21.
[0048] It also includes a release assembly, which includes a mounting groove 9 opened inside the key rod 21, and a third follower 91 movably installed in the mounting groove 9. A telescopic rod 92 is movably installed inside the third follower 91, and a retractable clip 93 is fixedly installed on the top of the telescopic rod 92.
[0049] The second driving member 94 is movably mounted on the bottom of the third driven member 91, and a driving rod 95 is fixedly mounted on the second driving member 94.
[0050] The inner width of the retractable card 93 is equal to the width of the slot 34, and when the retractable card 93 is in the assembled state, it is located directly below the claw 33.
[0051] Specifically, the machining surface 81 above the side leg bracket 1 includes mounting surfaces for linear guides, grating rulers, racks, etc., which require precision machining. After precision machining, it needs to be inspected using a multi-faceted inspection fixture 82. The multi-faceted inspection fixture 82 is adapted to the tool setting surface 8. After the side leg bracket 1 is machined, the machined surface 81 is inspected by moving the multi-faceted inspection fixture 82. However, after long-term use, the inspection surface of the multi-faceted inspection fixture 82 wears down, which can easily lead to inaccurate inspection. In this invention, the multi-faceted inspection fixture 82 is hollow inside, and through grooves are opened on its surface to reduce weight, thereby reducing the friction it experiences during inspection and thus reducing wear. On the other hand, 85 is also opened on 84, which is used when tightening bolt 71. Align 85 with the screw hole 7. After the bolt 71 is tightened, 85 can be fixed. Then, 87 is fixed to both ends of 84 with screws. Then, one end of 86 is fitted onto the outer surface of the key rod 21 and tightened with screws. The other end of 86 is provided with an insert head, and the corresponding 87 is provided with an insert groove for supporting 87. Both ends of the multi-faceted inspection fixture 82 are fixed with 83 that are compatible with 87. 87 can support the multi-faceted inspection fixture 82, reduce the friction on the inspection surface of the multi-faceted inspection fixture 82, make operation convenient, and ensure stable and reliable processing and measurement with high accuracy. It can check the consistency of each spacing dimension during the processing of the side leg bracket, realize the absolute measurement of the spacing dimension of each processing surface, and achieve a qualified inspection in one go.
[0052] Furthermore, when the processing and inspection operations are completed, the tooling needs to be disassembled. In this invention, the mating surfaces of the side leg bracket 1 and the tooling base 11 are both provided with slots. When the limiting claw 4 enters the limiting slot 41, the key rod 21 has already entered the mating surface of the side leg bracket 1 and the tooling base 11. As the limiting slot 41 continues to move, it will drive the drive rod 95, causing the drive rod 95 to drive the third driven member 91, thereby causing the third driven member 91 to move upward, and then push the retractable card 93 out of the mounting slot 9, as shown in the attached specification. Figure 6 Instruction manual attached Figure 12 Included with instruction manual Figure 13As shown, when disassembling the tooling, the slide rail assembly can be removed by first loosening bolt 71, and then all bolts 71 can be removed. A protrusion is provided at the connection between the retractable clip 93 and the telescopic rod 92. Using a long bolt or needle-nose pliers, the tool can be extended through the second through slot 13 to the protrusion of the retractable clip 93, lifting it upwards. At this time, the telescopic rod 92 will extend from the third follower 91, causing the retractable clip 93 to move upwards. When the retractable clip 93 moves upwards, it will constrain the claw 33, making its width match the slot 34. Under the elastic force provided by the first return spring 31, the first follower 32 will move downwards. This allows the claw 33 to enter the slot 34, and then the retractable clip 93 is released, causing the retractable clip 93 to reset and free up its position. At this time, under the continuous action of the first reset spring 31, the claw 33 disengages from the first follower 32, releasing the fixation of the side leg bracket 1 and the tooling base 11. The limiting claw 4 will also reset through the torsion spring without the interference of the first follower 32, releasing the limit on the key rod 21. Correspondingly, after the first follower 32 moves, it will drive the second follower 52 to move, causing the fastener 57 to release the fastening of the side leg bracket 1. Finally, the key rod 21 can be pulled out to achieve the purpose of quick disassembly and assembly.
[0053] In summary, it should be noted that both end faces of the side leg bracket 1 need to be processed. However, this invention only describes the processing method of one end face. The processing method of the other end face of the side leg bracket 1 can refer to the processing method described in this invention. Simply replace each component with the other side of the tooling base 11 to install it, and the other end face of the side leg bracket 1 can be adapted.
