Description

Technical Field

[0001] This utility model relates to the field of adjustment mechanism technology, and more specifically, to an adjustment mechanism for a drilling and milling machine. Background Technology

[0002] In the existing technology, the adjustment mechanism of a drilling and milling machine has serious functional limitations in adjusting the position of the milling cutter. The traditional manual adjustment system used in the existing mechanism is not good in terms of accuracy and flexibility, and it is difficult for operators to achieve precise movement and fine adjustment of the position of the milling cutter.

[0003] Existing mechanisms are not good at adjusting the position of the parts to be drilled and milled, and cannot easily complete the rotation and movement of the workpiece. Traditional worktable designs usually only provide simple XY plane movement and lack flexible angle adjustment functions. When it is necessary to process surfaces or holes with multiple different angles, operators have to frequently reinstall the workpiece or use additional tilting fixtures.

[0004] The existing mechanism has obvious shortcomings in the workpiece fixing process, and cannot easily and reliably fix the parts to be drilled and milled. Traditional fixture systems mostly use bolts for direct fixing, which is cumbersome and time-consuming. Each time the workpiece position is adjusted, the fixing bolts need to be completely loosened and then tightened again, which greatly extends the non-productive time. Utility Model Content

[0026] In this embodiment, the part to be drilled and milled is placed at one end of the rotating seat 24. Then, the fourth threaded rod 30 is rotated, causing the moving block 29, which is threadedly connected to the fourth threaded rod 30, to slide along the guide block 27. During the sliding movement, the clamping block 28 is moved, thereby completing the contact with the part to be drilled and milled. By rotating the rotating handle 22, the driving gear 23 is driven to rotate, and the driven gear 25, which is meshed with the driving gear 23, is driven to rotate, causing the rotating seat 24 to rotate. Then, by starting the fourth motor 16, the worm gear 17 at the output end is driven to rotate, causing the worm wheel 18, which is meshed with the worm gear 17, to rotate, thus completing the rotation of the rotating table 19. Then, by starting the electric push rod 8, the moving table 9 at the output end is driven to slide along the guide rail 15 on the fixed table 7. After sliding to the appropriate position, the drive is stopped.

[0027] Please see Figure 3-5 As an implementation of a milling machine adjustment mechanism for a clamping assembly: A clamping assembly is provided on a rotating table 19.

During rotation, the third movable frame 13, which is threadedly connected to the third threaded rod 12, slides along the second movable frame 10 to a suitable position. Thus, the milling cutter 14 on the third movable frame 13 completes the operation process of the part to be drilled and milled.

[0031] In summary, during the use or operation of the overall equipment: the part to be drilled and milled is placed at one end of the rotating seat 24. Then, the fourth threaded rod 30 is rotated, causing the moving block 29, which is threadedly connected to the fourth threaded rod 30, to slide along the guide block 27. During this sliding movement, the clamping block 28 is moved, thereby completing the contact with the part to be drilled and milled. By rotating the rotating handle 22, the driving gear 23 is driven to rotate, and the driven gear 25, which meshes with the driving gear 23, is driven to rotate, causing the rotating seat 24 to rotate. Then, by starting the fourth motor 16, the worm gear 17 at the output end is driven to rotate, causing the worm wheel 18, which meshes with the worm gear 17, to rotate, thus completing the rotation of the rotating table 19. Then, by starting the electric push rod 8, the moving table 9 at the output end is driven to slide along the guide rail 15 on the fixed table 7. After sliding to the appropriate position, the drive is stopped.

[0032] By starting the first motor 2 on the support frame 1, the first threaded rod 3 at its output end is rotated. During rotation, the first movable frame 4, which is threadedly connected to the first threaded rod 3, slides along the support frame 1. Then, by starting the second motor 5, the second threaded rod 6 at its output end is rotated. During rotation, the second movable frame 10, which is threadedly connected to the second threaded rod 6, slides along the first movable frame 4. After sliding to a suitable position, the second motor 5 is stopped. Then, by starting the third motor 11, the third threaded rod 12 at its output end is rotated. During rotation, the third movable frame 13, which is threadedly connected to the third threaded rod 12, slides along the second movable frame 10 to a suitable position.
