[0034] The following embodiments of the technical solution of the present invention are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and are therefore only used as examples, and cannot be used to limit the protection scope of the present invention.

[0035] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by those skilled in the art to which the present invention belongs.

[0036] See also Figure 1 , Figure 2 and Figure 3-8 As shown, the present invention provides a technical solution: a CNC machining detection probe, comprising a spindle box 1, a probe box 3 and a lifting mechanism 4, a fixture seat 11 is installed at the bottom of the spindle box 1, a mounting plate 2 is bolted to one side of the spindle box 1, the probe box 3 is installed on the surface of the mounting plate 2, the lifting mechanism 4 is installed at the bottom of the probe box 3, and a probe 5 is installed inside the probe box 3;

[0037] A box cover 31 is installed at the front end of the probe box 3, a motor compartment 32 is opened at the center of the inner wall of the probe box 3, a rotating assembly 33 is installed inside the motor compartment 32, a rotating disk 34 is installed on one side of the rotating assembly 33, and push-out assemblies 35 are evenly distributed on the surface of the rotating disk 34, and a push-out groove 36 is opened on the side of the probe box 3, and the opening of the push-out groove 36 is downward;

[0038] The lifting mechanism 4 includes a first-order guide rail 41, a lifting seat 42, a retracting assembly 43 and a second-order guide rail 44. The first-order guide rail 41 is installed at the bottom of the probe box 3, the lifting seat 42 is installed inside the first-order guide rail 41, the retracting assembly 43 is installed on the outside of the lifting seat 42, and the second-order guide rails 44 are symmetrically installed on both sides of the clamp seat 11.

[0039] It should be noted that the electrical components used in the present invention are all electrically connected to the controller of the CNC machine tool through wires, and unified control is performed by the CNC machine tool controller.

[0040] Furthermore, a positioning ring 311 is provided on the inner surface of the box cover 31. The surface of the positioning ring 311 is smooth and contacts the surface of the rotating disk 34. The spacing between the positioning ring 311 and the edge of the box cover 31 matches the side thickness of the probe box 3. A push-out groove 312 is provided on the side of the box cover 31. The opening of the push-out groove 312 faces downward, and the opening widths of the push-out groove 312 and the push-out groove 36 are consistent. During the rotation of the rotating disk 34, the positioning ring 311 supports and positions it, thereby preventing the rotating disk 34 from tilting, causing the probe 5 to disengage from the limiting groove 356, and causing damage to the probe 5.

[0041] Furthermore, an isolation plate 321 is installed on the inner wall of the motor bin 32, and a circular hole 322 is opened in the center of the surface of the isolation plate 321. A baffle 323 protruding outward is provided at the edge of the motor bin 32. The surface of the baffle 323 is smooth and contacts the surface of the rotating disk 34. Through the setting of the isolation plate 321, the first motor 331 is isolated from the transmission gear. At the same time, through the setting of the circular hole 322, the first motor 331 can be quickly connected to the driving tooth 332.

[0042] Furthermore, the rotating assembly 33 includes a first motor 331, a driving tooth 332, a driven tooth 333, an internal gear 334 and a support rod 335. The first motor 331 is installed at the center of the inner wall of the motor compartment 32. The output shaft of the first motor 331 passes through the circular hole 322. The output shaft end of the first motor 331 is installed with a driving tooth 332. The outer side of the driving tooth 332 is evenly meshed with the driven tooth 333. The driven teeth 333 are all meshed with the inner wall of the internal gear 334. The internal gear 334 is installed on the inner wall of the baffle 323. The inside of the driven tooth 333 is rotatably connected with the support rod 335 through a bearing. The other end of the support rod 335 is installed on one side of the rotating disk 34. The driving tooth 332, the driven tooth 333 and the internal gear 334 cooperate to form a complete planetary gear system. The driving tooth 332 drives the driven tooth 333 to rotate synchronously and uniformly on the inner side of the internal gear 334, and then the rotating disk 34 is driven to rotate uniformly through the support rod 335.

[0043] Furthermore, partition plates 341 are installed on the surface of the rotating disk 34, and the angle between the partition plates 341 is one hundred and twenty degrees. Through the setting of the partition plates 341, the rotating disk 34 is divided into three areas, and three different probes 5 can be installed accordingly for subsequent selection. The length of the partition plate 341 is smaller than the radius of the positioning ring 311, so that there is a gap between the partition plate 341 and the positioning ring 311, thereby ensuring the smooth movement of the rotating disk 34.

[0044] Furthermore, the ejection assembly 35 includes a fixed pile 351, a second motor 352, a lead screw 353, a nut seat 354, an electric push rod 355 and a limit groove 356. The fixed pile 351 is symmetrically installed on the surface of the rotating disk 34, and the second motor 352 is installed at one end of the fixed pile 351. The output shaft end of the second motor 352 is installed with a lead screw 353 together with the coupling. The outer side of the lead screw 353 is threadedly connected to the nut seat 354, and the inner side of the nut seat 354 is installed with an electric push rod 355. The electric push rod A limiting groove 356 is installed at the end of the piston rod of one 355, and the inner wall of the limiting groove 356 matches the outer wall of the probe 5. When the rotating disk 34 rotates the selected probe 5 to the ejection groove 2 36, at this time, the probe 5 is in a vertical downward state, and the height of the nut seat 354 is adjusted by the screw 353 until the bottom of the probe 5 passes through the moving groove 427, and then, the electric push rod 1 355 works to release the probe 5, so that the probe 5 completely falls into the moving groove 427, completing the action of the probe 5 being taken out of the warehouse.

[0045] It should be noted that at present, most probes 5 are shuttle-shaped, the fixed position of the limit groove 356 is the maximum diameter of the shuttle, and the fixed position corresponding to the movable groove 427 is the lower side of the shuttle, thereby avoiding affecting the transmission of the probe 5.

[0046] See also Figure 1 , Figure 2 and Figure 9-11 As shown, as another embodiment of the present invention, a bracket 411 is welded on one side of the first-order guide rail 41, and the bracket 411 is bolted to the outer wall of the spindle box 1. A guide groove 412 is provided on the inner side of the first-order guide rail 41. The maximum width of the guide groove 412 matches the width of the lifting seat 42. Through the setting of the guide groove 412, the sliding process of the lifting seat 42 is guided and positioned to prevent the lifting seat 42 from overturning.

[0047] Furthermore, a connecting rod 421 is installed on the inner side of the lifting seat 42, and a connecting seat 422 is installed on the other end of the connecting rod 421 away from the lifting seat 42, and an electric push rod 423 is installed inside the connecting seat 422, and a mounting seat 424 is provided at the piston rod end of the electric push rod 423, and a third motor 425 is provided inside the mounting seat 424, and a support seat 426 is installed on the output shaft end of the third motor 425, and a moving groove 427 is installed between the support seats 426, and the inner side of the moving groove 427 It is funnel-shaped. Through the setting of the second electric push rod 423, the height of the movable groove 427 can be adjusted, and the vertical distance between the movable groove 427 and the limit groove 356 can be reduced, so that the probe 5 can fall into the movable groove 427 more easily. When the lifting seat 42 descends at a uniform speed and enters the curved section of the second-order guide rail 44 through the curved section of the first-order guide rail 41, the direction of the movable groove 427 can be adjusted through the setting of the third motor 425, so that the probe 5 in the movable groove 427 always maintains a vertical upward state.

[0048] Furthermore, the winding assembly 43 includes a fixing hook 431, a traction rope 432, a roller 433, a fourth motor 434 and a fixing box 435. The fixing hook 431 is installed on the outer side of the lifting seat 42, the traction rope 432 is installed on the surface of the fixing hook 431 through a knot, the other end of the traction rope 432 is installed on the surface of the roller 433 through a knot, the roller 433 is installed on the outer side of the output shaft of the fourth motor 434, the fourth motor 434 is installed inside the fixing box 435, and the fixing box 435 is welded to the outer wall of the probe box 3. Through the setting of the winding assembly 43, the probe 5 can be lowered and retracted along the first-order guide rail 41 and the second-order guide rail 44.

[0049] It should be noted that when the lifting seat 42 moves along the first-order guide rail 41 and the second-order guide rail 44 , the fourth motor 434 and the third motor 425 are in a coordinated working state.

[0050] Furthermore, a guide groove 2 441 is provided on the inner side of the second-order guide rail 44, and the width of the guide groove 2 441 matches the width of the guide groove 1 412. A positioning block 442 is installed at the end of the second-order guide rail 44 away from the first-order guide rail 41, and a connecting rod 443 is installed on the outer side of the positioning block 442. A fifth motor 444 is installed inside the end of the connecting rod 443 away from the second-order guide rail 44, and a fixed seat 445 is installed at the output shaft end of the fifth motor 444. The fixed seats 445 are symmetrically fixedly connected to the two sides of the fixture seat 11. Through the setting of the fifth motor 444, when the probe 5 is not needed, the second-order guide rail 44 can be retracted outward to avoid affecting the processing of the tool. Through the setting of the positioning block 442, the lifting seat 42 can be stopped directly below the fixture seat 11.

[0051] It should be noted that when the second-order guide rail 44 is rotated to vertically downward by the fifth motor 444, the curved section of the second-order guide rail 44 can accurately match the curved section of the first-order guide rail 41. Secondly, the straight section of the second-order guide rail 44 is shorter and is rubber-matched with the width of the lifting seat 42. Through the retracting assembly 43, the lifting seat 42 can be lowered all the way to the straight section.

[0052] Working principle of the present invention:

[0053] The first step is to select a suitable probe 5 according to the requirements of the processed parts, and control the probe box 3 to start working through the CNC machine tool controller;

[0054] The second step is to start the first motor 331 to drive the active gear 332 to rotate, and then drive the driven gear 333 to rotate along the inner gear 334. Then, the support rod 335 drives the rotating disk 34 to rotate at a constant speed until the corresponding probe 5 moves to the second ejection slot 36, and the probe 5 remains vertically downward. Finally, the electric push rod 1 355 contracts, so that the probe 5 falls into the inside of the moving slot 427.

[0055] The third step is to start the lifting mechanism 4 through the CNC machine tool controller;

[0056] The fourth step is to start the fifth motor 444 to drive the connecting rod 443 to flip downward, so that the second-order guide rail 44 is combined with the first-order guide rail 41, and then start the second electric push rod 423 to lower the height of the moving groove 427, and then start the fourth motor 434 to uniformly lower the height of the lifting seat 42 through the traction rope 432 until one side of the lifting seat 42 is in contact with the positioning block 442, and finally, start the fifth motor 444 to push the probe 5 into the fixture seat 11, and fix the probe 5 through the fixture seat 11;

[0057] Step 5: After the detection task is completed according to the requirements, the probe 5 is reset through the cooperation of the lifting mechanism 4 and the ejection assembly 35 to facilitate the next use;

[0058] This completes the use process of a CNC machining detection probe.

[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
