[0035] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the invention, and should not be construed as limiting the invention.
[0036] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.
[0037] Example 1: See Figures 1-6The present invention provides a technical solution: a crankshaft milling machining center, including a base 1, a worktable 101 fixedly connected to the top of the base 1, a translation device 102 fixedly connected to the top of the base 1, a side plate 103 fixedly connected to the side of the base 1, a rotating disk 104 rotatably connected to the inner wall of the side plate 103 via bearings, a placement cylinder 105 fixedly connected to the inner wall of the rotating disk 104, and a push rod 106 fixedly connected to the outer wall of the placement cylinder 105, and further comprising:
[0038] The milling mechanism 2 includes a movable seat 201. The inner wall of the movable seat 201 is movably connected to the translation device 102. The inner wall of the movable seat 201 is rotatably connected to an annular plate 202 via a bearing. The inner wall of the annular plate 202 is fixedly connected to a housing 203. The inner wall of the housing 203 is fixedly connected to a pressure assembly 21. The top of the housing 203 is fixedly connected to a motor 204. The output end of the motor 204 is fixedly connected to a limiting ring 205. The outer wall of the limiting ring 205 is rotatably connected to the housing 203 via a bearing. The end of the limiting ring 205 away from the motor 204 is fixedly connected to a connecting post 206. The end of the connecting post 206 away from the limiting ring 205 is fixedly connected to a connector 207. The outer wall of the connector 207 has a through hole 208. The outer wall of the connector 207 is movably connected to a cutting edge assembly 22.
[0039] The working principle of this embodiment is as follows: When replacing the blade assembly 22, the milling mechanism 2 is moved to the top by the translation device 102, and then the blade assembly 22 is placed in the placement cylinder 105. Then, the push rod 106 is activated to disconnect the blade assembly 22 from the milling mechanism 2 and fix it in the placement cylinder 105. Then, the milling mechanism 2 is moved backward a certain distance. The rotating disk 104 is rotated to align the blade assembly 22 to be replaced with the milling mechanism 2. The milling mechanism 2 is moved forward and the push rod is retracted, so that the placement cylinder 105 is released from fixing the blade assembly 22 and a connection is established between the blade assembly 22 and the milling mechanism 2.
[0040] Example 2: Based on Example 1, please refer to... Figures 7-8The pressure assembly 21 includes a push rod 211. The inner wall of the outer casing 203 is fixedly connected to the push rod 211. An annular plate 212 is fixedly connected to the end of the push rod 211 away from the outer casing 203. A sliding column 213 is movably connected to the inner wall of the annular plate 212. A spring 214 is sleeved on the outer wall of the sliding column 213. The top of the spring 214 is fixedly connected to the sliding column 213, and the bottom of the spring 214 is fixedly connected to the annular plate 212. The sliding column 213 passes through the outer casing 203 and extends to the outside of the outer casing 203. The outer wall of the sliding column 213 is movably connected to the outer casing 203. A movable ring 215 is fixedly connected to the bottom of the sliding column 213. A rotating ring 216 is rotatably connected to the side of the movable ring 215 away from the sliding column 213 via a bearing. The side of the rotating ring 216 away from the movable ring 215 is fixed. The rotating ring 216 is connected to a protruding column 217 and has a circular hole 218 at its top. A push rod 219 is fixedly connected to the inner wall of the outer shell 203, and a movable rod 2110 is fixedly connected to the bottom of the push rod 219. Before the blade assembly 22 needs to be replaced, the push rod 219 will be started to move the movable rod 2110 downward. Then the motor 204 will be started to rotate the blade assembly 22. At this time, since the protruding column 217 on the rotating ring 216 is embedded in the positioning groove 225, the rotating ring 216 will also rotate until the circular hole 218 on the rotating ring 216 coincides with the movable rod 2110 and the movable rod 2110 is embedded in the circular hole 218. Then the motor 204 will stop. At this time, the device has also completed the angle reset. The movable rod 2110 slides through the annular plate 212 and extends to the bottom of the movable ring 215.
[0041] The working principle of this embodiment is as follows: After the basic replacement of the blade assembly 22 is completed, the second push rod 211 drives the second annular plate 212 to move towards the blade assembly 22. The moving annular plate 212 drives the first sliding column 213 to move through the spring. The moving sliding column 213 drives the rotating plate through the movable ring 215 to apply pressure to the blade assembly 22, thereby increasing the pressure between the through hole 208 in the connector 207 and the blade assembly 22, thus starting the fixing effect. At the same time, the protruding column on the rotating ring will also be embedded in the positioning groove 225, further preventing the blade assembly 22 from shaking.
[0042] Example 2: Based on Example 1, please refer to... Figures 9-12The cutting edge assembly 22 includes a second outer shell 221. A milling cutter 222 is fixedly connected to the bottom of the second outer shell 221. A central column 223 is fixedly connected to the inner wall of the second outer shell 221. A placement frame 224 is fixedly connected to the top of the central column 223. The top of the placement frame 224 is fixedly connected to the second outer shell 221. A positioning groove 225 is provided on the top of the second outer shell 221. The inner wall of the positioning groove 225 is movably connected to the protruding column 217. A circular hole 3 227 is provided on the outer wall of the second outer shell 221. A circular hole 226 is provided on the inner wall of the placement frame 224. A sliding column 228 is fixedly connected to the inner wall of the second outer shell 221. A sliding column 3 229 is fixedly connected to the inner wall of the second outer shell 221. An auxiliary component 23 is movably connected to the outer wall of the sliding column 3 229.
[0043] Auxiliary component 23 includes a fixed post 231, the outer wall of which is movably connected to a circular hole 227. A circular plate 232 is fixedly connected to one end of the fixed post 231 near the central post 223. A spring 233 is sleeved on the outer wall of the fixed post 231. One end of the spring 233 is fixedly connected to a housing 221, and the other end of the spring 233 away from the housing 221 is fixedly connected to the circular plate 232. A connecting plate 234 is fixedly connected to the outer wall of the circular plate 232. A slider 235 is fixedly connected to the outer wall of the connecting plate 234. The inner wall of the slider 235 is movably connected to a sliding post 229. A second slider is fixedly connected to the outer wall of the connecting plate 234. 236, the inner wall of slider 236 is movably connected to slider 228, and a locking pin 237 is fixedly connected to the end of connecting plate 234 away from circular plate 232. The outer wall of locking pin 237 is movably connected to circular hole 226 and through hole 208. When the connection between the cutting edge assembly 22 and the milling mechanism 2 is released, push rod 106 will be embedded in circular hole 227 and push fixed pin 231 to move. The moving fixed pin 231 will drive locking pin 237 out of through hole 208 through circular plate 232, connecting plate 234, and then release the connection between cutting edge assembly 22 and milling mechanism 2.
[0044] The working principle of this embodiment is as follows: When establishing a connection between the cutting edge assembly 22 and the connector 207, the connector 207 is first inserted into the placement frame 224, and then the push rod 106 is activated to retract it. At this time, the outer side of the fixing post 231 loses the support of the push rod 106, and then moves outward under the action of the spring 233. The fixing post 231, which moves outward, drives the locking post 237 to move towards the placement frame 224 through the circular plate 232 and the connecting plate 234. Then, the locking post 237 passes through the circular hole 226 and is embedded in the through hole 208, so that the cutting edge assembly 22 and the milling mechanism 2 are connected.
