[0024] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that the description of these embodiments is for the purpose of helping to understand this utility model, but does not constitute a limitation on this utility model.
[0025] Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.
[0026] Please refer to Figures 1-5. This utility model discloses a modular quick-change milling machine tool, which includes a worktable 1, and a change-up component 3 and a clamping component 2 are provided on the upper surface of the worktable 1.
[0027] In embodiment 1, the replacement assembly 3 includes a slider 31, a threaded rod 32, a robotic arm 33, a connecting box 35, a milling drill bit 36, a placement rack 37, a moving plate 39, a stop plate 310, a connecting plate 311, and a limiting block 313. The side of the slider 31 is slidably connected to the inner wall of the worktable 1. The two ends of the threaded rod 32 are rotatably connected to the inner wall of the worktable 1. The inner wall of the slider 31 is threadedly connected to the surface of the threaded rod 32. The bottom end of the robotic arm 33 is connected to the upper end face of the slider 31. The side wall of the robotic arm 33 is rotatably connected to the upper end face of the connecting box 35. The side of the moving plate 39 is slidably connected to the inner wall of the connecting box 35. The top end of the limiting block 313 is connected to the lower end face of the moving plate 39. The side of the milling drill bit 36 is slidably connected to the side wall of the connecting box 35. The side of the stop plate 310 is slidably connected to the inner wall of the connecting box 35. The two ends of the connecting plate 311 are connected to the stop plate 310 and the moving plate 39. The side of the mechanical arm 33 is rotatably connected. The bottom end of the placement frame 37 is connected to the upper end face of the worktable 1. The upper end face of the mechanical arm 33 is connected to the first servo motor 34. The output end of the first servo motor 34 passes through the side wall of the mechanical arm 33 and is connected to the upper end face of the connecting box 35. The side of the worktable 1 is connected to the second servo motor 38. The output end of the second servo motor 38 passes through the inner wall of the worktable 1 and is connected to one end of the threaded rod 32. The upper end face of the moving plate 39 is connected to the spring 312. The top end of the spring 312 is connected to the inner wall of the connecting box 35. The top end of the milling drill bit 36 has a groove with the same shape as the limiting block 313. The side of the limiting block 313 is engaged with the inner wall of the groove. The side of the limiting block 313 is slidably connected to the inner wall of the connecting box 35. The side of the milling drill bit 36 is slidably connected to the inner wall of the placement frame 37. The side of the connecting box 35 is slidably connected to the inner wall of the placement frame 37.
[0028] Specifically, the components of the replacement assembly 3 work together closely to achieve rapid replacement of the milling drill bit 36. When the milling drill bit 36 needs to be replaced, the second servo motor 38 on the side of the worktable 1 is started first. The output end of the second servo motor 38 drives the threaded rod 32 to rotate clockwise. Since the slider 31 is threadedly connected to the threaded rod 32 and the side of the slider 31 is slidably connected to the inner wall of the worktable 1, the slider 31 will move to the right along the inner wall of the worktable 1. The movement of the slider 31 drives the robotic arm 33 to move to the right synchronously. The speed and distance of the robotic arm 33 are precisely controlled by the rotation speed and number of rotations of the second servo motor 38.
[0029] When the robotic arm 33 moves to the placement rack 37, the first servo motor 34 on the upper surface of the robotic arm 33 starts. The output end of the first servo motor 34 drives the connecting box 35 to rotate clockwise. During the rotation of the connecting box 35, by observing the position of the milling drill bit 36 inside the placement rack 37, the first servo motor 34 precisely controls the rotation angle of the connecting box 35 so that the position of the connecting box 35 corresponds precisely to the position of the milling drill bit 36 to be replaced.
[0030] In embodiment 2, the clamping assembly 2 includes a first clamping plate 21, a second clamping plate 22, a limiting rod 23, and hydraulic rods 24. The two ends of the limiting rod 23 are connected to the lower end face of the worktable 1. The sides of the first clamping plate 21 and the second clamping plate 22 are slidably connected to the inner wall of the worktable 1. The inner walls of the first clamping plate 21 and the second clamping plate 22 are slidably connected to the surface of the limiting rod 23. The sides of the two hydraulic rods 24 are connected to the lower end face of the worktable 1. The side of the first clamping plate 21 is connected to the telescopic end of one of the hydraulic rods 24, and the side of the second clamping plate 22 is connected to the telescopic end of the other hydraulic rod 24.
[0031] Specifically, the clamping assembly 2 is mainly used for clamping and releasing workpieces to ensure the stability of the workpieces during processing. When clamping the workpiece, two hydraulic rods 24 are activated. The two hydraulic rods 24 are synchronous telescopic hydraulic rods, and their telescopic ends extend simultaneously. The telescopic end of one hydraulic rod 24 pushes the first clamping plate 21 connected to it, and the telescopic end of the other hydraulic rod 24 pushes the second clamping plate 22.
[0032] Since the sides of the first clamping plate 21 and the second clamping plate 22 are slidably connected to the inner wall of the worktable 1, and their inner walls are slidably connected to the surface of the limiting rod 23, the first clamping plate 21 and the second clamping plate 22 can only move relative to each other along the direction of the limiting rod 23 under the push of the hydraulic rod 24. As the hydraulic rod 24 continues to push, the first clamping plate 21 and the second clamping plate 22 gradually approach each other. When they contact the workpiece placed on the worktable 1, pressure is continued to be applied so that the workpiece is firmly clamped between the first clamping plate 21 and the second clamping plate 22. During the clamping process, the output pressure of the hydraulic rod 24 can be adjusted according to the material and shape of the workpiece to ensure that the clamping force can ensure that the workpiece does not shift during processing and will not be damaged due to excessive pressure.
[0033] Working principle:
[0034] First, the hydraulic rod 24 in the clamping assembly 2 is activated. The extension end of the hydraulic rod 24 drives the first clamping plate 21 and the second clamping plate 22 connected thereto to move. Since the first clamping plate 21 and the second clamping plate 22 are slidably connected to the inner wall of the worktable 1, and the inner wall is slidably connected to the surface of the limiting rod 23, the two can move relative to each other along the direction of the limiting rod 23 under the action of the hydraulic rod 24. When the two are close, the workpiece placed on the worktable 1 can be clamped and fixed. When they are far apart, the workpiece is released, which is convenient for loading and unloading.
[0035] The operation of the replacement component 3 is achieved by motor drive. The second servo motor 38 on the side of the worktable 1 is started, and its output end drives the threaded rod 32 to rotate. The slider 31, which is threadedly connected to the threaded rod 32, slides on the inner wall of the worktable 1, thereby driving the connected robotic arm 33 to move. The robotic arm 33 moves to the placement rack 37, and the first servo motor 34 on the upper end of the robotic arm 33 is started, driving the connecting box 35 to rotate, so that the connecting box 35 corresponds to the position of the milling drill bit 36 to be replaced in the placement rack 37. The moving plate 39 in the connecting box 35 is pushed down by the elastic force of the spring 312, and the limiting block 313 is inserted into the groove at the top of the milling drill bit 36 to complete the initial positioning. Then, the moving plate 39 slides in the connecting box 35, and the connecting plate 311 drives the abutment plate 310 to move. The abutment plate 310 pushes the milling drill bit 36 out of the placement rack 37 and moves it to a suitable processing position. After the replacement is completed, the reverse operation can be performed to put the used milling drill bit 36 back into the placement rack 37.
[0036] After the milling drill bit 36 is installed in place, the machine tool control system starts the milling drill bit 36 to rotate at high speed. The robotic arm 33, driven by the slider 31, can move above the worktable 1 to move the milling drill bit 36 to a suitable position above the workpiece, and perform milling on the clamped workpiece. According to the preset program, the required shape and features are cut out. At this point, the entire workflow is completed.
[0037] The above-mentioned front, back, left, right, top, and bottom are all based on Figure 1 in the accompanying drawings of the instruction manual.
