[0021] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0022] This application discloses a CNC lathe tool breakage detection device, referring to... Figure 1 and Figure 2 In this embodiment, the detection device includes a mounting base plate 1, a movable adjustment mechanism, a fixed sleeve 2, a first fastener, a fixed sleeve 3, a second fastener, a driving component, a driving tube 5, a rotating sleeve 6, a locking mechanism, a detection arm 7, and a detection probe 8. The mounting base plate 1 is securely mounted inside the CNC lathe by several screws. The fixed sleeve 2 is slidably mounted on the surface of the mounting base plate 1 via the movable adjustment mechanism, which allows for effective adjustment of the position of the entire device.

[0023] One end of the fixing sleeve 3 is installed inside the fixing frame 2 via a first fastener, while the other end of the fixing sleeve 3 extends outside the fixing frame 2. Specifically, in this embodiment, the first fastener includes a first fastening edge 31 and a first fastening bolt 32; wherein, the first fastening edge 31 is fixedly installed on the outer side of one end of the fixing sleeve 3, and the first fastening edge 31 is located inside the fixing frame 2 and abuts against the inner side of the fixing frame 2; at the same time, a plurality of first fastening threaded holes are provided on both the first fastening edge 31 and the inner side of the fixing frame 2, and a plurality of first fastening bolts 32 are provided, and the first fastening bolts 32 are threadedly connected to the first fastening threaded holes respectively.

[0024] In this way, by using the first fastening bolts 32 to be screwed into the first fastening edge 31 and the inner side of the fixing sleeve 2 along the first fastening threaded holes, the first fastening edge 31 can be firmly installed on the inner side of the fixing sleeve 2, thereby realizing the fixing sleeve 3 being firmly installed on one side of the fixing sleeve 2.

[0025] Additionally, refer to Figure 2 and Figure 3 In this embodiment, the driving component is a drive motor 4. The drive motor 4 is mounted on the first fastening edge 31 of the fixed sleeve 3 by a second fastener, and the drive motor 4 is located inside the fixed sleeve 2. The output shaft of the drive motor 4 extends into the interior of the fixed sleeve 3.

[0026] Specifically, in this embodiment, the second fastener includes a second fastening edge 41 and a second fastening bolt 42; wherein, the second fastening edge 41 is fixedly installed on the outside of the drive motor 4, and the second fastening edge 41 is located inside the fixed sleeve 2 and abuts against one side of the first fastening edge 31; at the same time, a plurality of second fastening threaded holes are provided on both the second fastening edge 41 and the first fastening edge 31, and a plurality of second fastening bolts 42 are provided, and the second fastening bolts 42 are threadedly connected to the second fastening threaded holes respectively.

[0027] By using the second fastening bolts 42 to be screwed into the second fastening edge 41 and the first fastening edge 31 in sequence along the second fastening threaded holes, the second fastening edge 41 can be securely installed on one side of the first fastening edge 31, thereby enabling the drive motor 4 to be securely installed on one side of the first fastening edge 31.

[0028] In addition, refer to Figure 2 and Figure 3In this embodiment, one end of the drive tube 5 is sleeved on the outside of the output shaft of the drive motor 4, and the other end of the drive tube 5 extends out of the fixed sleeve 3; and a pin groove is provided on both the outside of the output shaft of the drive motor 4 and the inside of one end of the drive tube 5, and a pin is installed between the two pin grooves. In this way, the output shaft of the drive motor 4 is fixedly connected to the inside of one end of the drive tube 5 by the pin, so that when the drive motor 4 is started, the output shaft of the drive motor 4 can drive the drive tube 5 to rotate.

[0029] Meanwhile, in this embodiment, the rotating sleeve 6 is rotatably sleeved on the outside of the fixed sleeve 3, and a limiting ring edge is installed on one side of the rotating sleeve 6. A limiting ring groove that cooperates with the limiting ring edge is opened on one side of the fixed sleeve 2. In this way, the setting of the limiting ring edge and the limiting ring groove can effectively guide and position the rotating sleeve 6.

[0030] The locking mechanism is located between the rotating sleeve 6 and the drive tube 5, so that the rotating sleeve 6 is mounted on the outside of the drive tube 5, thereby enabling the drive tube 5 to drive the rotating sleeve 6 to rotate. One end of the detection arm 7 is located on the outside of the rotating sleeve 6; specifically, a rotating tube 62 is installed on the outside of the rotating sleeve 6, a fastening internal thread 63 is provided on the inner side of the rotating tube 62, and a fastening external thread 71 is provided on the outer side of one end of the detection arm 7, which is threadedly connected to the fastening internal thread 63.

[0031] In this way, the detection arm 7 is screwed into the internal thread 63 of the rotating tube 62 by the external thread 71, thereby making the detection arm 7 securely installed on the rotating sleeve 6; conversely, the detection arm 7 can be screwed out from the inside of the rotating tube 62, and thus the detection arm 7 can be removed from the rotating sleeve 6.

[0032] Secondly, refer to Figure 2 and Figure 3 In this embodiment, the detection probe 8 is installed on the end of the detection arm 7 away from the rotating sleeve 6. The detection probe 8 is a 3D probe sensor, which can accurately detect the tool. When the drive motor 4 is started, the output shaft of the drive motor 4 drives the drive tube 5 to rotate, and the drive tube 5 drives the detection arm 7 on the rotating sleeve 6 to rotate. This allows the detection arm 7 to drive the 3D probe sensor to detect the tool installed in the lathe, thereby enabling timely detection of whether the tool is worn or broken.

[0033] Meanwhile, by electrically connecting the detection probe 8 to the control system of the CNC lathe, if normal wear is detected in the current tool, the wear value can be automatically updated to the tool compensation parameters; if excessive wear is detected in the tool, it can be treated as tool damage or breakage, thus allowing for the selection of a new tool to be replaced for the next workpiece machining, or the machine can be automatically stopped and an alarm can be triggered to prompt the operator to replace the tool. It should be noted that this 3D probe sensor is existing technology and will not be elaborated upon here.

[0034] Therefore, by setting up a detection structure in which the mounting base plate 1, the moving adjustment mechanism, the fixed sleeve 2, the first fastener, the fixed sleeve 3, the second fastener, the driving component, the driving tube 5, the rotating sleeve 6, the locking mechanism, the detection arm 7, and the detection probe 8 cooperate with each other, the tool can be accurately detected before use. This allows for timely detection of whether the tool is worn or broken, thereby reducing the possibility of more tool losses or even the scrapping of a batch of workpieces.

[0035] The structure of the moving adjustment mechanism and the locking mechanism is described in detail below:

[0036] Specifically, refer to Figure 1 and Figure 2 In this embodiment, the movable adjustment mechanism includes a movable sliding sleeve 21, a sliding seat 11, a limiting component, and a blocking component. The movable sliding sleeve 21 is mounted on the outer side of the fixed sleeve 2; the sliding seat 11 is mounted on the top surface of the mounting base plate 1, and the movable sliding sleeve 21 and the sliding seat 11 slide against each other, allowing the entire detection device to slide on the sliding seat 11 of the mounting base plate 1 via the movable sliding sleeve 21. This facilitates effective adjustment of the position of the entire detection device, enabling the 3D probe sensor on the detection arm 7 to more accurately detect the cutting tools installed inside the lathe.

[0037] Preferably, when the detection device is not needed, the entire detection device can be moved to one side inside the lathe, thereby preventing the cutting tool from being obstructed during machining. Alternatively, in another embodiment, the movable sleeve 21 can be driven by a moving device such as a cylinder, enabling automatic movement and adjustment of the entire device, thus improving its automation level.

[0038] Meanwhile, two limiting components are provided, symmetrically installed on both sides of the movable sliding sleeve 21. Through the setting of these two limiting components, the movable sliding sleeve 21 can be stably limited on the mounting base plate 1. Specifically, in this embodiment, the limiting component includes a limiting seat 22, a limiting screw 24, a limiting knob 25, and a limiting block 26.

[0039] The limiting seat 22 is installed on one side of the movable sliding sleeve 21; and a limiting threaded hole 23 is opened on the limiting seat 22, and the limiting screw 24 is threadedly connected in the limiting threaded hole 23; the limiting knob 25 is installed on the top of the limiting screw 24; the limiting block 26 is installed at the end of the limiting screw 24 away from the limiting knob 25, and the limiting block 26 cooperates with the mounting base plate 1.

[0040] When the entire device is moved to the designated position, the limit knob 25 is rotated. Since the limit screw 24 is threadedly connected to the limit threaded hole 23 in the limit seat 22, the limit screw 24 drives the limit block 26 to press against the surface of the mounting base plate 1, thereby achieving the effect of effectively and stably positioning the entire detection device.

[0041] Better, refer to Figure 1 In this embodiment, scale values ​​12 are provided on both sides of the surface of the mounting base 1, and a pointing end 27 is provided at the front end of the limiting seat 22. The pointing end 27 cooperates with the scale values ​​12. By setting the scale values ​​12 and the pointing end 27 to cooperate with each other, the distance the entire detection device moves can be more clearly known, thereby achieving more precise adjustment of the position of the entire detection device.

[0042] At the same time, refer to Figure 2 and Figure 3 In this embodiment, two blocking components are provided, and the two blocking components are symmetrically installed on both sides of the sliding seat 11. By setting the two blocking components, the moving sliding sleeve 21 can be effectively blocked, so as to prevent the entire detection device from sliding out of the sliding seat 11 when adjusting the position of the entire detection device.

[0043] Specifically, in this embodiment, the blocking assembly includes a blocking plate 14 and countersunk bolts 17. The blocking plate 14 has an L-shaped structure and blocking grooves 13 are formed on both sides of the sliding seat 11. One side of the blocking plate 14 cooperates with the blocking groove 13, allowing one side of the blocking plate 14 to be inserted into the groove of the blocking groove 13. Symmetrical blocking holes 15 are formed on the side of the blocking plate 14 that is inserted into the blocking groove 13, and symmetrical countersunk threaded holes 16 communicating with the blocking groove 13 are formed on the sliding seat 11. When one side of the blocking plate 14 is inserted into the blocking groove 13, the two blocking holes 15 on the blocking plate 14 correspond to the two countersunk threaded holes 16 on the sliding seat 11.

[0044] Meanwhile, two countersunk bolts 17 are provided, each threadedly connected to one of the two countersunk threaded holes 16, and each of the two countersunk bolts 17 engages with one of the two blocking holes 15. By screwing the countersunk bolts 17 into the countersunk threaded holes 16 and then through the blocking holes 15, the blocking plate 14 can be securely installed on one side of the sliding seat 11 to block the moving sliding sleeve 21, thereby preventing the entire detection device from sliding out of the sliding seat 11.

[0045] Additionally, refer to Figure 2 and Figure 3 In this embodiment, the locking mechanism includes a rotating ring seat 61 and a locking ring 53. The rotating ring seat 61 is installed inside the rotating sleeve 6, and an annular groove 51 is formed on the outer side of the end of the drive tube 5 away from the drive motor 4. The rotating ring seat 61 is sleeved on the outer side of the annular groove 51. The locking ring 53 is sleeved on the outer side of the annular groove 51. The locking ring 53 is located on the side of the rotating ring seat 61 away from the fixed sleeve 2 and cooperates with the rotating ring seat 61.

[0046] Meanwhile, a locking external thread 52 is provided on the outer groove wall of the annular side groove 51, and a locking internal thread 54 is provided on the inner side of the locking ring 53, which is threadedly connected to the locking external thread 52. This allows the locking ring 53 to be screwed into the annular side groove 51 to securely abut against the rotating ring seat 61, thereby ensuring that the rotating sleeve 6 is securely installed on one end of the drive tube 5. When the drive tube 5 rotates, it can drive the rotating sleeve 6 to rotate.

[0047] Preferably, a number of torsion grooves 55 are provided on the outer side of the locking ring 53; the torsion grooves 55 are clamped and locked by a clamping tool, and then the clamping tool is rotated, so that the locking ring 53 can be easily twisted into the drive tube 5, so as to securely install the rotating sleeve 6 on the drive tube 5; or it can be easily twisted out of the drive tube 5, so as to disassemble the rotating sleeve 6.

[0048] In addition, refer to Figure 2 and Figure 3 In this embodiment, a bearing assembly 56 is also installed on the outside of the drive tube 5. The inner side of the bearing assembly 56 is sleeved on the outside of the drive tube 5, and the outer side of the bearing assembly 56 abuts against the inner side of the fixing sleeve 3. Simultaneously, a locking ring disc 57 is also sleeved on the outside of the drive tube 5. The locking ring disc 57 abuts against the bearing assembly 56, and the outer side of the locking ring disc 57 is threadedly connected to the inner side of the fixing sleeve 3. Specifically, the outer side of the locking ring disc 57 has an external thread 59, and the inner side of the fixing sleeve 3 has an internal thread 33 that is threadedly connected to the external thread 59. Furthermore, several torsion holes 58 are also provided on the locking ring disc 57.

[0049] By inserting a clamping tool into the rotating holes 58, the locking ring disc 57 is clamped and secured. Then, the clamping tool is rotated, causing the locking ring disc 57 to be rotated into the interior of the fixing sleeve 3, so as to achieve a stable positioning effect on the bearing assembly 56, thereby making the drive tube 5 rotate more smoothly.

[0050] Secondly, in this embodiment, a cover plate 9 is installed on the side of the fixed sleeve 2 away from the fixed sleeve 3 by multiple bolts, and a cover plate 9 is also installed on the side of the rotating sleeve 6 away from the fixed sleeve 2 by multiple bolts. By setting these two cover plates 9, not only can the components inside the fixed sleeve 2 and the components inside the rotating sleeve 6 be effectively protected and isolated, but also when the two cover plates 9 are removed, it is easy to effectively disassemble the components inside the fixed sleeve 2 and the components inside the rotating sleeve 6.
