[0062] Furthermore, if Figures 6-7As shown, the Z-axis driving mechanism 42 is installed on the front side of the support plate 41, and the Z-axis driving mechanism 42 includes a lower moving block 42a, and the lower moving block 42a is connected and fixed to the upper end of the flexible shaft 45i to drive the flexible shaft 45i to rise and fall. The sliding mechanism 43 is installed on the front side of the support plate 41, and the sliding mechanism 43 includes a connecting block 431, and the connecting block 431 can slide relative to the support plate 41. The connecting block 431 is connected and fixed to the middle shaft sleeve 45h. Preferably, the middle shaft sleeve 45h 5h is a T-shaped shaft sleeve, and its upper flange is also pressed against the top of the connecting block 431. The connecting block 431 is abutted against the top of the lower moving block 42a. The clamping mechanism 44 is located below the connecting block 431 and is fixedly connected to the sliding mechanism 43 and can slide relative to the support plate 41.

Preferably, the gauge shaft seat sleeve 45k is a T-shaped shaft sleeve, and its upper flange is also pressed against the top of the clamping mechanism 44 that clamps the gauge shaft seat sleeve 45k.
[0063] The automatic thread gauge detection equipment having the die-casting thread hole gauge detection module 40 provided by the embodiment of the utility model can realize the adaptive gauge 45l detection of the threaded holes of the die-casting. Even if there are some non-vertical threaded holes, automatic detection can still be realized. It is particularly suitable for the detection of threaded holes with high precision requirements for the numerical values of the thread teeth of the threaded holes, replacing manual labor, with higher production efficiency and more guaranteed detection quality.
[0064] Combine Figures 1 to 11 The working principle of the automatic thread gauge detection device having the die-casting thread hole gauge detection module 40 provided by the embodiment of the utility model is described in detail:
[0065] During operation, the die-casting that needs to be inspected for threaded holes is loaded on the mounting platform 20, and then the die-casting threaded hole gauge inspection module 40 connected thereto is moved to the top of the threaded hole of the die-casting by driving and controlling the XY axis moving device 30; at this time, the clamping mechanism 44 first clamps the outer periphery of the gauge shaft seat sleeve 45k, and the Z axis driving mechanism 42 of the die-casting threaded hole gauge inspection module 40 controls its lower moving block 42a to move downward, because the lower moving block 42a is fixedly connected to the upper end of the flexible shaft 45i, then the lower moving block 42a will drive the flexible shaft 45i and the plum directly or indirectly connected to the flexible shaft 45i during the downward movement process. The flower shaft 45e, the lower universal joint 45f, the middle connecting shaft 45g, the middle shaft sleeve 45h, the flexible shaft 45i, the tooth gauge shaft seat 45j, the tooth gauge shaft seat sleeve 45k and the tooth gauge 45l are all moved downward relative to the support plate 41 with the sliding mechanism 43 as the guide. The plum blossom shaft 45e is in a sleeve fit with the plum blossom shaft sleeve 45d, so the plum blossom shaft 45e can move downward relative to the plum blossom shaft sleeve 45d until the tooth gauge 45l contacts or approaches the edge of the threaded hole of the die-casting. The Z-axis drive mechanism 42 is paused and the clamping mechanism 44 releases its clamping of the tooth gauge shaft seat sleeve 45k. At this time, the servo motor 45a starts the forward transmission, driving the upper spindle 45b to rotate, and the upper spindle 45b is The upper universal joint 45c drives the plum blossom shaft sleeve 45d to rotate, and the plum blossom shaft 45e also rotates because it cooperates with the plum blossom shaft sleeve 45d. The plum blossom shaft 45e drives the middle connecting shaft 45g to rotate through the lower universal joint 45f. Under the action of the middle shaft sleeve 45h, the connecting block 431 of the sliding mechanism 43 will not interfere with the rotation of the middle connecting shaft 45g. Then the middle connecting shaft 45g drives the flexible shaft 45i to rotate, and the flexible shaft 45i drives the tooth gauge shaft seat 45j to rotate, thereby realizing the control of the tooth gauge 45l to rotate. The rotating tooth gauge 45l is screwed into the threaded hole of the die casting until it is screwed into the bottom of the threaded hole. The servo motor 45a is paused. In this process, due to the setting There is a soft shaft 45i, and the clamping mechanism 44 has released the clamping of the gauge shaft seat sleeve 45k. Then, even if the threaded hole to be inspected is not a vertical hole, the gauge 45l can be screwed into the threaded hole under the swing of the soft shaft 45i and the gauge shaft seat sleeve 45k, thereby realizing self-adaptation. At this time, the Z-axis drive mechanism 42 starts to reset, and the servo motor 45a starts to reverse until the gauge 45l is controlled to be screwed out of the threaded hole of the die-casting. The servo motor 45a records the number of circles of the gauge 45l screwed out of the threaded hole, thereby completing the inspection of a single threaded hole. The number of circles can be calculated by software later to determine whether the threaded hole meets the requirements.
[0066] It should be noted that the thread gauge automatic detection equipment in the embodiment of the present invention also needs to use a controller to control the electric components in the entire equipment, and accordingly a software program needs to be set up. Since the embodiment of the present invention requests protection for the structural scheme, those skilled in the art can implement the design of the corresponding software based on the structural scheme disclosed in this embodiment. This embodiment does not make unnecessary elaborations on the software that cooperates with it.
[0067] In one embodiment of the present invention, Figures 8-9 As shown, the die-cast threaded hole gauge inspection module 40 also includes a ball bearing 45n, which is sleeved onto the outside of the middle connecting shaft 45g and located above the middle shaft sleeve 45h. Specifically, the provision of ball bearing 45n ensures that the middle connecting shaft 45g can still rotate with sufficient lubrication even when heated by friction during operation, thereby ensuring the reliability of the die-cast threaded hole gauge inspection module 40 for long-term, high-intensity use.
[0068] In one embodiment of the present invention, Figure 5 and 10As shown in Figures 11 to 11, the Z-axis drive mechanism 42 also includes a support frame 42b, a Z-axis motor 42c, a Z-axis screw rod 42d, a Z-axis nut 42e, an upper moving block 42f, a guide shaft 42g, an upper guide sleeve 42h, a lower guide sleeve 42i and a tension spring (not shown). The support frame 42b is fixedly mounted on the front side of the support plate 41, and an upper cantilever block 42b1, a middle cantilever block 42b2 and a lower cantilever block 42b3 are provided on the support frame 42b. The Z-axis motor 42c is mounted on the upper cantilever block 42b1 and is arranged downward. The Z-axis screw rod 42d is driven and connected to the Z-axis motor 42c and passes through the middle cantilever block 42b2, the upper moving block 42f and the lower cantilever block 42b3 in sequence. Behind the lower moving block 42a, its bottom end is rotatably connected to the lower cantilever block 42b3, the Z-axis nut 42e is threadedly connected to the Z-axis screw rod 42d and fixed on the upper moving block 42f, the guide shaft 42g is vertically connected between the middle cantilever block 42b2 and the lower cantilever block 42b3, the upper guide sleeve 42h and the lower guide sleeve 42i are both sleeved outside the guide shaft 42g, and the upper guide sleeve 42h is connected and fixed to the upper moving block 42f, the lower guide sleeve 42i is connected and fixed to the lower moving block 42a, the lower end of the tension spring is connected to the lower moving block 42a, and the upper end of the tension spring is connected to the top of the support plate. Specifically, the support frame 42b is locked and connected to the front side of the support plate 41 as a supporting mounting structure. On the same side, an upper cantilever block 42b1, a middle cantilever block 42b2 and a lower cantilever block 42b3 are provided. The Z-axis motor 42c drives the Z-axis screw rod 42d to rotate, and the Z-axis nut 42e threadedly connected to the Z-axis screw rod 42d moves downward, thereby driving the upper moving block 42f connected to the Z-axis nut 42e to move downward. During the downward movement of the upper moving block 42f, the upper guide sleeve 42h will press the lower guide sleeve 42i, thereby forcing The lower moving block 42a connected to the lower guide sleeve 42i moves downward, and the lower moving block 42a is fixedly connected to the upper end of the flexible shaft 45i. Then, in the process of moving downward, the lower moving block 42a will drive the flexible shaft 45i and the plum blossom shaft 45e directly or indirectly connected to the flexible shaft 45i, the lower universal joint 45f, the middle connecting shaft 45g, the middle shaft sleeve 45h, the flexible shaft 45i, the gauge shaft seat 45j, the gauge shaft seat sleeve 45k and the gauge 45l to move downward relative to the support plate 41 guided by the sliding mechanism 43.Among them, the lower moving block 42a also stretches the tension spring connected to it at the bottom during the downward movement. Then, when the Z-axis motor 42c starts to reset, it only controls the upper moving block 42f to move up, and the lower moving block 42a still remains in a lower position to ensure that the gauge 45l is screwed into the threaded hole for detection. When the gauge 45l is reversed and screwed out of the threaded hole, the lower moving block 42a is pulled up by the tension spring connected to the top of the support plate, and then drives the gauge 45l to move up and wait for the next work. This structure cleverly avoids the reset of the Z-axis motor 42c directly driving the rise of the gauge 45l indirectly controlled by it, and ensures that the descending and screwing-in actions of the gauge 45l are separately controlled.
[0069] In one embodiment of the present invention, Figure 5 and 10 As shown in Figures 11 to 12, the sliding mechanism 43 further includes a fixed slider 432, a sliding guide rail 433, an upper L-shaped block 434, and a lower L-shaped block 435. The fixed slider 432 is connected and fixed to the front side of the support plate 41. The sliding guide rail 433 is slidably connected to the fixed slider 432. The upper L-shaped block 434 and the lower L-shaped block 435 are arranged vertically and connected and fixed to the sliding guide rail 433. The connecting block 431 is connected and fixed to the upper L-shaped block 434, and the clamping mechanism 44 is connected and fixed to the lower L-shaped block 435. Specifically, the fixed slider 432 is connected and fixed to the front side of the support plate 41 as a stationary member, while the sliding guide rail 433, which slidably cooperates with it, serves as a movable member capable of sliding up and down relative to the fixed slider 432. Thus, when the flexible shaft 45i is driven downward by the lower moving block 42a, the connecting block 431 also moves downward under the guidance of the sliding guide rail 433, and the clamping mechanism 44 also moves downward under the guidance of the sliding guide rail 433, achieving synchronization and ensuring that the arrangement of the connecting block 431 and the clamping mechanism 44 does not interfere with the normal upward and downward movement of the thread gauge 45l. The arrangement of the upper L-shaped block 434 and the lower L-shaped block 435 allows the connecting block 431 and the clamping mechanism 44, which are connected to the sliding guide rail 433, to be separated by a distance from the sliding guide rail 433, ensuring safety and reliability in use.
[0070] In one embodiment of the present invention, Figure 5As shown, the sliding mechanism 43 further includes a limit switch 436 and a sensing plate 437. The limit switch 436 is mounted on the front side of the support plate 41. The sensing plate 437 is connected to the sliding guide rail 433 and senses the limit switch 436 when the sliding guide rail 433 rises to a set position. Specifically, when the sliding guide rail 433 moves up to a certain height, the sensing plate 437 connected thereto senses the limit switch 436 mounted on the front side of the support plate 41. At this time, the height signal of the sliding guide rail 433 can be transmitted to the controller, which implements overall control and sends corresponding signals for executing other programs to the servo motor 45a and the Z-axis motor 42c.
[0071] In one embodiment of the present invention, as shown in the figure, the clamping mechanism 44 includes a finger cylinder 441 and two arc-shaped clamping blocks 442. The finger cylinder 441 is connected and fixed to the lower L-shaped block 435. The two arc-shaped clamping blocks 442 are respectively connected and fixed to the two fingers of the finger cylinder 441. Under the drive of the finger cylinder 441, the two arc-shaped clamping blocks 442 can clamp the gauge shaft seat sleeve 45k. Specifically, the finger cylinder 441 controls the closing of the two arc-shaped clamping blocks 442, thereby being able to adapt and clamp to the outer periphery of the gauge shaft seat sleeve 45k and abut against the upper flange of the gauge shaft seat sleeve 45k. Controlling the loosening of the two arc-shaped clamping blocks 442 can release the clamping of the gauge shaft seat sleeve 45k. The structure is simple and applicable.
[0072] In one embodiment of the present invention, Figure 5 As shown, the die-casting threaded hole gauge detection module 40 further includes a CCD industrial camera 46, which is mounted on the front side of the support plate 41. Specifically, because the CCD industrial camera 46 is mounted on the support plate 41, it is driven by the XY axis movement device 30 in synchronization with the other components of the die-casting threaded hole gauge detection module 40. Through it, the threaded hole on the die-casting can be photographed and calibrated.
