Description

Technical Field

[0001] This invention belongs to the field of CNC machine tool technology, specifically relating to a motion platform for a multi-axis linkage machine tool. Background Technology

[0002] In the field of multi-axis machine tools, the motion platform, as the core component that carries the workpiece and realizes multi-degree-of-freedom motion, is undergoing continuous technological evolution from the traditional serial superposition structure to parallel and hybrid drive directions. With the increasing demands for machining flexibility for complex curved parts, motion platforms are developing towards high rigidity, large tilt angle, and multi-degree-of-freedom integration. Hybrid motion platforms have become a research hotspot because they combine the large stroke of serial mechanisms with the high rigidity of parallel mechanisms. In some existing multi-axis machine tools, the motion platform can usually only adjust the horizontal rotation of the workpiece, and does not have the function of adjusting the tilt angle of the workpiece in the front-back or left-right directions. When it is necessary to process workpieces with complex inclined surfaces or spatial angles, it is not possible to directly adjust the tilt posture of the workpiece through the motion platform. It is often necessary to use an additional angle head and perform multiple clamping adjustments, which increases the number of processing steps, prolongs the auxiliary time, and the multiple clamping can easily introduce positioning errors, affecting the processing accuracy and efficiency.

Detailed Implementation To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Example 1 Reference Figure 1 This is the first embodiment of the present invention. This embodiment provides a motion platform for a multi-axis linkage machine tool, including a moving component, including a base 10. A first moving component 11 is mounted on the top right side of the base 10. A second moving component 13 is mounted on the first moving component 11. A first cylinder 14 is mounted on the second moving component 13. The output end of the first cylinder 14 is fixedly connected to a machining head 15. A sliding component 12 is mounted on the right end of the base 10. A first drive component 16 is fixedly connected to the top of the base 10. A rotating disk 21 is fixedly connected to the top of the first drive component 16. A second drive component 18 is mounted on the top of the rotating disk 21. A rotating component 19 is mounted on the second drive component 18. An electric chuck disk 20 is mounted on the top of the rotating component 19. The electric chuck disk 20 is prior art and will not be described in detail here. Reference Figure 2The first moving component 11 includes two support plates 111 and a slide groove 112 formed on the top of the base 10. Two support plates 111 are fixedly connected to the top right side of the base 10, and a lead screw 113 is rotatably connected between the two support plates 111. A first motor 115 for driving the lead screw 113 to rotate is fixedly connected to the surface of the support plate 111 near the front side of the base 10. A bracket 114 is slidably connected inside the slide groove 112. The bracket 114 is threaded onto the outside of the lead screw 113. A limiting plate 116 that is slidably connected to the right end face of the base 10 is fixedly connected to the outer side of the bottom end of the bracket 114. The first motor 115 is controlled to work and drive the lead screw 113 to rotate. The rotation of the lead screw 113 drives the bottom end of the bracket 114 to slide inside the slide groove 112, thereby realizing the displacement of the bracket 114, which facilitates the adjustment of the front and rear position of the processing head 15. Reference Figure 2 The second moving component 13 includes a sliding hole 131 formed on the bracket 114. A sliding block 132 is slidably connected inside the sliding hole 131. The sliding block 132 is arranged in a "+" shape. An electric push rod 133 is fixedly connected to the outside of the bracket 114. The output end of the electric push rod 133 passes through the bracket 114 and is fixedly connected to the sliding block 132. A through hole is formed in the middle of the sliding block 132. A first cylinder 14 is fixedly connected inside the through hole. The operation of the electric push rod 133 drives the sliding block 132 to move inside the sliding hole 131. The movement of the sliding block 132 drives the first cylinder 14 and the machining head 15 to move, thereby enabling the adjustment of the left and right position of the machining head 15. Reference Figure 1 and Figure 2 The sliding assembly 12 includes a sliding groove 121 formed on the right end face of the base 10. A sliding plate 122 is slidably connected inside the sliding groove 121. The sliding plate 122 is fixedly connected to the inner surface of the limiting plate 116. The sliding plate 122, in conjunction with the sliding groove 121, further improves the stability of the support 114 when it moves. Reference Figure 6 The first drive assembly 16 includes two support plates 161 fixedly connected to the top of the base 10 and a rotating shaft 164 rotatably connected to the top of the base 10. A worm gear 163 is rotatably connected between the two support plates 161. A second motor 162 for driving the worm gear 163 to rotate is fixedly connected to the surface of the support plate 161 near the front of the base 10. A worm wheel 165 is fixedly connected to the outer side of the rotating shaft 164, and the worm gear 163 and the worm wheel 165 are meshed together. The second motor 162 drives the worm gear 163 to rotate, and the rotation of the worm gear 163 drives the worm wheel 165 to rotate, thereby causing the rotating shaft 164 to rotate. The rotation of the rotating shaft 164 can drive the rotating disk 21, the second drive assembly 18, the rotating assembly 19, and the electric chuck disk 20 to rotate. Reference Figure 5The second drive assembly 18 includes two upright plates 181 fixedly connected to the top of the base 10. A slide rail 183 is fixedly connected between the two upright plates 181. A sliding plate 184 is slidably sleeved on the outer side of the slide rail 183. A fixing frame 185 is fixedly connected to the top of the sliding plate 184. A fixing column 186 is fixedly connected to the inner side of the fixing frame 185. Multiple annular grooves 187 are opened on the outer side of the fixing column 186. A second cylinder 182 is fixedly connected to the outer side of the upright plate 181 near the right end of the base 10. The output end of the second cylinder 182 passes through... The vertical plate 181 is fixedly connected to the fixed frame 185. The second cylinder 182 drives the fixed frame 185 to move. The movement of the fixed frame 185 causes the sliding plate 184 to slide on the outside of the slide rail 183. At the same time, the movement of the fixed frame 185 drives the fixed column 186 to move. The multiple annular grooves 187 opened on the outside of the fixed column 186 can drive the gear 195 to rotate. The rotation of the gear 195 drives the shaft 198 and the rotating frame 196 to rotate, thereby driving the top plate 197 and the electric chuck disk 20 to rotate to the left or right. Reference Figure 3 and Figure 4 The rotating assembly 19 includes a third motor 191 and a rotating shaft 192. The third motor 191 is fixedly connected to the outer side of one of the upright plates 181, and the rotating shaft 192 is rotatably connected to the outer side of the other upright plate 181. A connecting frame 193 is fixedly sleeved on the outer side of the output end of the third motor 191 and the outer side of the rotating shaft 192. A frame plate 194 is fixedly connected between the two connecting frames 193. Two shafts 198 are symmetrically rotatably connected on the frame plate 194. A gear 195 is fixedly connected between the two shafts 198. A rotating frame 196 is fixedly connected to the opposite ends of the two shafts 198. A top plate 197 is fixedly connected to the top of the rotating frame 196. An electric chuck disk 20 is fixedly connected to the top of the top plate 197. The gear 195 is meshed with the fixed column 186 through multiple annular grooves 187. The operation of the third motor 191 drives one of the connecting frames 193 to rotate. The rotation of the connecting frame 193 drives the frame plate 194 and the other connecting frame 193 to rotate. The other connecting frame 193 rotates outside the rotating shaft 192. Since the gear 195 is mounted on two shafts 198 that are rotatably mounted on the frame plate 194, and the gear 195 is meshed with the fixed column 186 through multiple annular grooves 187, the gear 195 is limited. Therefore, when the frame plate 194 rotates, it can drive the gear 195 to rotate in the annular grooves 187 opened on the fixed column 186, thereby driving the rotating frame 196 and the top plate 197 to rotate. The rotation of the top plate 197 can drive the electric chuck disk 20 to rotate forward or backward. In use, the workpiece to be processed is clamped and fixed on the electric chuck disk 20. The first motor 115 in the first moving assembly 11 is activated, driving the lead screw 113 to rotate. The lead screw 113 drives the bracket 114 to slide inside the slide groove 112. As the bracket 114 moves, it drives the limiting plate 116 to slide along the sliding groove 121. The limiting plate 116 drives the sliding plate 122 to slide inside the sliding groove 121, thereby adjusting the front-to-back position of the machining head 15. The electric push rod 133 in the second moving assembly 13 is activated, driving the sliding block 132 to slide inside the sliding hole 131. The sliding block 132 drives the first cylinder 14 and the machining head 15 to move, thereby adjusting the left-to-right position of the machining head 15. The first cylinder 14 is activated, pushing the machining head 15 up and down, thus adjusting the height of the machining head 15. The machining head 15 is moved to the position to be processed by the above XYZ three-axis movement. The second motor 162 in the first drive assembly 16 is started. The second motor 162 drives the worm gear 163 to rotate. The worm gear 163 drives the worm wheel 165 to rotate. The worm wheel 165 drives the rotating shaft 164 to rotate. The rotating shaft 164 drives the rotating disk 21, the second drive assembly 18, the rotating assembly 19 and the electric chuck disk 20 to rotate as a whole, so as to realize the rotational positioning of the workpiece in the horizontal plane. The second cylinder 182 in the second drive assembly 18 is activated, which pushes the fixed frame 185 to move. The fixed frame 185 drives the sliding plate 184 to slide along the slide rail 183, and at the same time, the fixed frame 185 drives the fixed column 186 to move. When the fixed column 186 moves, the annular groove 187 on its outer side drives the gear 195 to rotate. The gear 195 drives the shaft 198 and the rotating frame 196 to rotate. The rotating frame 196 drives the top plate 197 and the electric chuck disk 20 to rotate left or right, thereby adjusting the left and right tilt angle of the workpiece. The third motor 191 in the rotating assembly 19 is activated, driving one of the connecting frames 193 to rotate. This connecting frame 193 drives the frame plate 194 and another connecting frame 193 to rotate synchronously. The other connecting frame 193 rotates outside the rotating shaft 192. During the rotation of the frame plate 194, the gear 195 engages with the fixed column 186 through the annular groove 187 to achieve a limiting position. The gear 195 rolls in the annular groove 187 on the fixed column 186, thereby driving the rotating frame 196 and the top plate 197 to rotate forward or backward. The top plate 197 drives the electric chuck disk 20 to rotate forward or backward, realizing the adjustment of the workpiece's tilt angle. Through the coordinated movement of the above structure, the workpiece held on the electric chuck disk 20 is realized to move in space with multiple degrees of freedom. In conjunction with the XYZ three-axis movement of the machining head 15, multi-axis linkage machining is completed. Example 2 Reference Figure 1This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a limiting component, including a fixing plate 22 fixedly connected to the top of the base 10 and a rotation limiting component 17 installed on the outside of the rotating disk 21. Reference Figure 7 The limiting component 17 includes an annular groove 171 formed on the outer side of the rotating disk 21. An annular plate 172 is rotatably connected inside the annular groove 171, and the bottom end face of the annular plate 172 is fixedly connected to the top end face of the fixed plate 22. When the rotating disk 21 rotates, it rotates outside the annular plate 172 through the annular groove 171, thereby improving the stability of the rotating disk 21 during rotation. In use, as the rotating disk 21 rotates, the annular groove 171 on the outer side of the rotating disk 21 rotates on the outer side of the annular plate 172. The bottom end face of the annular plate 172 is fixedly connected to the top end of the fixing plate 22, which is fixedly connected to the top of the base 10. Through the sliding engagement between the annular groove 171 and the annular plate 172, the rotation of the rotating disk 21 is guided and supported, reducing the shaking of the rotating disk 21 during rotation and improving the stability and positioning accuracy of the rotating disk 21. It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
