DETAILED DESCRIPTION
[0031] The present application is further described in detail below in conjunction with the accompanying drawings.
[0032] The embodiment of the present application discloses a multi-station milling machine. Figure 1 The multi-station milling machine includes a bed 1, a mounting seat 7, a cylinder 10, a worktable 2, a rotating shaft 3 and a milling cutter 31. The top surface of the bed 1 is horizontally arranged, and the height direction of the bed 1 is vertically arranged. The mounting seat 7 is slidably arranged on the top surface of the bed 1 along the width direction of the bed 1, and the mounting seat 7 is arranged horizontally; the cylinder 10 is fixedly connected to the top surface of the bed 1, and the cylinder 10 is arranged along the width direction of the bed 1. The piston rod end of the cylinder 10 is fixedly connected to the mounting seat 7, so that the cylinder 10 can drive the mounting seat 7 to move. The worktable 2 is arranged on the top surface of the mounting seat 7, and the worktable 2 is arranged horizontally. The length direction of the worktable 2 is parallel to the length direction of the bed 1; three placement areas are arranged on the top surface of the worktable 2 along its own length direction for placing workpieces 11. The rotating shaft 3 is arranged along the length direction of the bed 1, and the rotating shaft 3 is arranged on the bed 1 to rotate around its own axis. A power part is also arranged on the bed 1, and the power part is a motor. The output shaft of the power part is coaxially fixedly connected with the rotating shaft 3. The milling cutter 31 is a three-sided milling cutter, which is coaxially arranged on the rotating shaft 3. There are three milling cutters 31, which are arranged at intervals along the length direction of the rotating shaft 3, so that three workpieces 11 can be milled at the same time, thereby improving work efficiency.
[0033] In order to ensure the placement effect of the workpiece 11 and facilitate the subsequent clamping and fixing of the workpiece 11, refer to Figure 2 A marking line 21 is arranged on the top surface of the workbench 2 in each placement area.
[0034] Reference Figure 1 and Figure 2A clamping assembly 4 is provided in each placement area on the workbench 2, and the clamping assembly 4 includes a first screw 41, a second screw 42 and a clamping plate 43. The first screw 41 and the second screw 42 are parallel to the rotating shaft 3, and the first screw 41 and the second screw 42 are coaxially arranged; the first screw 41 and the second screw 42 are arranged at intervals, and the thread directions of the first screw 41 and the second screw 42 are opposite; the first screw 41 and the second screw 42 are both arranged on the top surface of the workbench 2 to rotate around their own axes. There are two clamping plates 43, which correspond to the first screw 41 and the second screw 42 respectively. The two clamping plates 43 are respectively arranged at one end of the first screw 41 and the second screw 42 close to each other, and the two clamping plates 43 are arranged at intervals and in parallel; the two clamping plates 43 are both slidably arranged on the top surface of the workbench 2, and the sliding direction is parallel to the axis of the rotating shaft 3. The two clamping plates 43 are fixedly connected to the sides away from each other with threaded barrels 431, and the threaded barrels 431 are provided with internal threads. The threaded barrels 431 on the side close to the first screw rod 41 are threadedly connected to the first screw rod 41, and the threaded barrels 431 on the side close to the second screw rod 42 are threadedly connected to the second screw rod 42. Therefore, after placing the workpiece 11 between the two clamping plates 43, the first screw rod 41 and the second screw rod 42 are rotated in the same direction, so that the two threaded barrels 431 can be brought close to each other, and the two clamping plates 43 can be brought close to each other, so that the workpiece 11 is clamped and fixed.
[0035] In order to make the process of clamping the workpiece 11 easier, refer to Figure 2 The workbench 2 is provided with a driving assembly 5, which includes a rotating power member 51, a rotating rod 52, a driving gear 53, a first driven gear 54 and a second driven gear 55. The rotating power member 51 is a motor, which is fixedly connected to the top surface of the workbench 2 by bolts, and the output shaft of the rotating power member 51 is parallel to the rotating shaft 3. The rotating rod 52 is coaxially fixedly connected to the output shaft of the rotating power member 51. There are three first driven gears 54, which correspond to the three first screw rods 41 respectively, and the first driven gears 54 are coaxially fixedly connected to the ends of the corresponding first screw rods 41; there are three second driven gears 55, which correspond to the three second screw rods 42 respectively, and the second driven gears 55 are coaxially fixedly connected to the ends of the corresponding second screw rods 42. The driving gear 53 is coaxially fixedly connected to the rotating rod 52, and there are six driving gears 53, which are arranged at intervals along the length direction of the rotating rod 52; the first driven gear 54 and the second driven gear 55 are both meshed with the corresponding driving gear 53. Therefore, after the rotating power member 51 is started, it can drive the rotating rod 52 to rotate, the rotating rod 52 drives the driving gear 53 to rotate, and the driving gear 53 drives the first driven gear 54 and the second driven gear 55 to rotate, so that the first screw 41 and the second screw 42 rotate in the same direction, so that the two clamping plates 43 are close to each other to clamp the workpiece 11. Since the three groups of clamping plates 43 clamp and fix the workpiece 11 at the same time, the working process is simpler and the working efficiency is higher.
[0036] Furthermore, a stopper 6 is fixedly connected to the side where the two clamps 43 are close to each other. The stopper 6 and the clamp 43 are vertically arranged, so that the stopper 6 can block the workpiece 11 in the process of moving toward the side close to the milling cutter 31, thereby preventing the workpiece 11 from shifting during the milling process, which helps to ensure the milling effect.
[0037] In order to facilitate the adjustment of the milling depth, the height of the workbench 2 is adjustable. Figure 3 A guide rod 72 and an adjusting screw 71 are provided on the top surface of the mounting seat 7, and both the guide rod 72 and the adjusting screw 71 are arranged vertically. The guide rod 72 is fixedly connected to one end of the mounting seat 7, and the guide rod 72 is slidably penetrated on the workbench 2, so that the workbench 2 and the guide rod 72 are slidably connected. The adjusting screw 71 is rotatably arranged on the mounting seat 7 around its own axis, and a threaded hole is provided on the workbench 2, and the workbench 2 and the adjusting screw 71 are threadedly connected. Therefore, under the restriction of the guide rod 72, the workbench 2 can be slid in the vertical direction by rotating the adjusting screw 71, so as to adjust the height of the workbench 2, adjust the distance between the milling cutter 31 and the workpiece 11 placed on the workbench 2, and thus realize the adjustment of the milling depth.
[0038] In order to facilitate the cleaning of the chips generated during the milling process, refer to Figure 3 and Figure 4 , a cleaning assembly 8 is also provided on the bed 1. The cleaning assembly 8 includes a blower 81, a connecting pipe 82 and an air outlet pipe 83. The blower 81 and the connecting pipe 82 are both fixedly connected to the bed 1, and the connecting pipe 82 is connected to the output end of the blower 81; the connecting pipe 82 is arranged along the length direction of the bed 1; the air outlet pipe 83 is welded to the connecting pipe 82, one end of the air outlet pipe 83 is connected to the inside of the connecting pipe 82, and the other end of the air outlet pipe 83 is opened for blowing air. There are three air outlet pipes 83, which correspond to the three placement areas respectively. The three air outlet pipes 83 are arranged at intervals along the length direction of the connecting pipe 82, and each air outlet pipe 83 is located above the corresponding placement area. Therefore, during the milling process, the blower 81 is started, and the blower 81 can blow air outward through the connecting pipe 82 and the air outlet pipe 83, thereby blowing away the debris accumulated on the workbench 2.
[0039] In order to collect the dust blown off, a collection box 9 is fixedly connected to the bed 1 at the side away from the milling cutter 31, and the opening of the collection box 9 faces upward. During the milling process, the workbench 2 first drives the workpiece 11 to slide toward the side close to the milling cutter 31, and then the workbench 2 drives the workpiece 11 to slide in the opposite direction to the initial position. When the workbench 2 returns to the initial position, debris is accumulated on the workbench 2. At this time, the wind blown out by the air outlet 83 can blow the debris off, so that the debris falls into the collection box 9, so as to facilitate the cleaning and collection of the debris.
[0040] Furthermore, the air outlet duct 83 is inclined, the air outlet of the air outlet duct 83 is downwardly disposed, and the air outlet of the air outlet duct 83 is toward the side close to the collection box 9, so that the air outlet duct 83 can more easily blow the debris on the workbench 2 into the collection box 9, which helps to enhance the cleaning effect.
[0041] The implementation principle of a multi-station milling machine in the embodiment of the present application is as follows: the workpiece 11 to be processed is placed in the marking lines 21 of the three placement areas respectively, and then the rotating power member 51 is started, the rotating power member 51 drives the rotating rod 52 to rotate, the rotating rod 52 drives the driving gear 53 to rotate, and the driving gear 53 drives the first driven gear 54 and the second driven gear 55 to rotate, so that the first screw 41 and the second screw 42 rotate in the same direction. Since the threads of the first screw 41 and the second screw 42 rotate in opposite directions, the two clamping plates 43 move to the side close to each other until the two clamping plates 43 clamp the workpiece 11. Then the piston rod of the cylinder 10 extends, and the cylinder 10 drives the mounting seat 7 and the workbench 2 to move, so that the workpiece 11 moves to the side close to the milling cutter 31, and the high-speed rotating milling cutter 31 can perform milling processing on the workpiece 11. After the milling process is completed, the piston rod of the cylinder 10 is retracted, so that the mounting seat 7 and the workbench 2 move in the opposite direction until they return to the initial position. After the workbench 2 moves to the initial position, the rotating power part 51 is started in reverse to make the clamps 43 move away from each other, and then the workpiece 11 is removed; at this time, the blower 81 blows air outward through the connecting pipe 82 and the air outlet pipe 83, and the debris accumulated in the placement area on the workbench 2 can be blown into the collection box 9, thereby facilitating the placement of the next batch of workpieces 11.
[0042] The above are optional embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
