[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0020] Please see Figures 1-4This utility model provides a technical solution: a high-precision machining center for mechanical parts, including a base 1 and a machining tool 7. A position adjustment component 3 is fixedly installed on the top of the base 1. A height adjustment component 4 is fixedly installed on the movable end of the position adjustment component 3. A drive motor 5 is fixedly installed on the movable end of the height adjustment component 4. A tool mounting seat 6 is fixedly installed on the output end of the drive motor 5. The machining tool 7 is detachably mounted in the tool mounting seat 6. A tool monitoring component 8 is provided on the outer wall of the drive motor 5. The position adjustment component 3 adjusts the height adjustment component 4 in the X and Y axis directions, thereby adjusting the position of the machining tool 7 in the two axis directions. The height adjustment component 4 adjusts the position of the machining tool 7 in the Z axis direction to achieve three-axis adjustment. The drive motor 5 drives the tool mounting seat 6 to rotate, thereby driving the machining tool 7 to rotate for machining. The tool monitoring component 8 monitors the tilt angle and position of the machining tool 7 to ensure the accuracy during machining.
[0021] The tool monitoring assembly 8 includes a mounting ring 801, which is fixedly mounted on the outer wall of the drive motor 5. Four mounting seats 802 are fixedly arranged at the edge of the mounting ring 801 in a circumferential array. Each mounting seat 802 is rotatably connected to a rotating shaft 805 via a bearing. A rotating seat 803 is fixedly sleeved on the outer wall of the rotating shaft 805. A position sensor 804 is fixedly mounted at the bottom end of the rotating seat 803. An angle adjustment component 806 is connected to the rotating shaft 805. Adjusting the rotation angle of the rotating shaft 805 via the angle adjustment component 806 adjusts the rotation angle of the rotating seat 803, thereby changing the orientation of the position sensor 804. The probe end is aligned with the smooth, regular section (cylindrical section) on the machining tool 7. During the tool lifting stage of the tool jump (at this time, the machining tool 7 is not in contact with the workpiece), the distance from the probe end of the position sensor 804 to the bottom of the machining tool 7 is monitored from four directions to see if it changes. If the distance does not change relative to the initial stage, the machining tool 7 has not shifted its position. If the distance changes relative to the initial stage, the position of the machining tool 7 has shifted. At this time, the machine can be stopped to adjust the machining tool 7, thereby ensuring the accuracy of machining. Since the orientation of the position sensor 804 is adjusted by the angle adjustment component 806, the probe end of the position sensor 804 can also be aligned with the smooth, regular section on the machining tool 7 when changing the machining tool 7.
[0022] The angle adjustment component 806 includes an electric telescopic rod 8061 and a turntable 8065. The electric telescopic rod 8061 is fixedly mounted on the mounting ring 801. A connecting ring 8062 is fixedly mounted on the telescopic end of the electric telescopic rod 8061. A connecting plate 8063 is fixedly mounted on the bottom of the connecting ring 8062. A hinge plate 8064 is fixedly mounted on the bottom of the connecting plate 8063. The turntable 8065 is fixedly mounted on the end of the rotating shaft 805. The bottom end of the hinge plate 8064 is rotatably connected to the edge of the turntable 8065 through a pin. The electric telescopic rod 8061 drives the connecting ring 8062 to move up and down, which in turn drives the connecting plate 8063 to move up and down. This causes the hinge plate 8064 at the bottom of the connecting plate 8063 to pull the turntable 8065 to rotate, which in turn drives the rotating shaft 805 to rotate, thereby adjusting the rotation angle of the rotating shaft 805.
[0023] A wire harness channel 10 and a wireless signal transmitter 11 are fixedly installed on the top of the connecting ring 8062. The wireless signal transmitter 11 is electrically connected to the position sensor 804 through a wire harness. The wireless signal transmitter 11 is also electrically connected to a battery 9 through a wire harness. The battery 9 is fixedly installed on the top of the mounting ring 801. The battery 9 is electrically connected to the position sensor 804 through a wire harness. The wire harness connecting the wireless signal transmitter 11 to the position sensor 804 passes through the wire harness channel 10. The position sensor 804 is powered by the battery 9. The data detected by the rotating shaft 805 is transmitted to the controller of the machining center through the wireless signal transmitter 11. The wire harness channel 10 is set to organize the wire harness and prevent it from becoming tangled.
[0024] The position adjustment component 3 includes a guide rail 301, which is fixedly installed on the top of the base 1. A mounting bracket 302 is fixedly installed at the rear end of the guide rail 301. A servo motor 303 is fixedly installed inside the mounting bracket 302. The output end of the servo motor 303 is connected to a lead screw 304 via a coupling. The lead screw 304 passes through the outer wall of the guide rail 301 via a bearing. A movable seat 305 is threaded onto the outer wall of the lead screw 304. The movable seat 305 is slidably disposed inside the guide rail 301. A servo motor 306 is fixedly installed on the outer wall of the movable seat 305. A lead screw 307 is connected to the output end of the servo motor 306 via a coupling. A mounting plate 309 is threaded onto the outer wall of the lead screw 307. The height adjustment component 4 is fixedly installed on the mounting plate 309. A guide rod 308 is fixedly installed on the outer wall of the movable seat 305. The mounting plate 309 is slidably disposed on the guide rod 308.
[0025] The height adjustment assembly 4 includes a second mounting bracket 401, which is fixedly mounted on the mounting plate 309. A third mounting bracket 402 is fixedly mounted on the top of the second mounting bracket 401. A third servo motor 403 is fixedly mounted inside the third mounting bracket 402. The output end of the third servo motor 403 is connected to a third lead screw 404 via a coupling. A connecting seat 406 is threaded on the outer wall of the third lead screw 404. A drive motor 5 is fixedly mounted inside the connecting seat 406. A second guide rod 405 is fixedly mounted inside the second mounting bracket 401. The connecting seat 406 is slidably mounted on the second guide rod 405.
[0026] A processing plate 2 is fixedly installed on the top of the base 1. The processing plate 2 is located below the processing tool 7. The top of the processing plate 2 has multiple threaded holes 201. By installing a fixture corresponding to the workpiece on the processing plate 2, the workpiece will not shift its position during processing.
[0027] Working principle: In use, the machining tool 7 is installed on the tool mounting seat 6. The operator, through visual observation, activates the electric telescopic rod 8061 to extend and retract, thereby causing the connecting ring 8062 to move up or down, which in turn causes the connecting plate 8063 to move up and down. This causes the hinge plate 8064 at the bottom of the connecting plate 8063 to pull the turntable 8065 to rotate, which in turn causes the rotating shaft 805 to rotate. The rotation of the rotating shaft 805 adjusts the rotation angle of the rotating seat 803, and then changes the orientation of the position sensor 804 so that its detection end is aligned with the smooth, regular section on the machining tool 7. The workpiece is then placed on the machining plate 2 and fixed using a fixture. Then, the position of the machining tool 7 in the X and Y axes is adjusted by the position adjustment component 3, and the position of the machining tool 7 in the Z axis is adjusted by the height adjustment component 4. The drive motor 5 is turned on to drive the tool mounting seat 6 to rotate, which in turn drives the machining tool 7 to rotate and process the workpiece. During the tool lifting stage of the tool jump, the distance from the detection end of the position sensor 804 to the bottom of the machining tool 7 is monitored from four directions to see if it changes. If the distance does not change relative to the initial stage, the machining tool 7 has not shifted its position. If the distance changes relative to the initial stage, the position of the machining tool 7 has shifted. At this time, the machine can be stopped to adjust the machining tool 7, thereby ensuring the accuracy of machining.
