[0009] A further improvement of this utility model is that: the internal cross-sectional shape of the connecting end is set as a rounded square, and the connecting end and one end of the rotating rod form a locking structure. There are two ball head protrusions, and the ball head protrusions form a locking structure with the connecting end through the spring. By utilizing the locking structure formed by the ball head protrusions, the rotating rod and the connecting end can be easily fixed when connected.

[0010] A further improvement of this utility model is that the steering component includes a support plate and a second movable rod. The support plate is fixedly connected to the surface of the placement plate. A motor is fixedly connected to one side of the support plate. A first gear is fixedly connected to the output end of the motor. A second gear is meshed with one side of the first gear. When the motor is started, the motor drives the first gear to rotate, and the first gear drives the second gear to rotate.

[0011] A further improvement of this utility model is that: a first movable rod is fixedly connected to the surface of the second gear, the first movable rod is movably connected to the inside of the support plate, the second movable rod is movably connected to the inside of the support plate, one end of the first movable rod is fixedly connected to the outside of the locking mechanism, and the second gear drives the first movable rod to rotate on the support plate, thereby driving the locking mechanism to adjust the angle.

It is equipped with a planar thread. When it is necessary to clamp and lock the tool, the tool is first placed in the middle of the collet. Then, the motor is powered on to drive the indexing plate on the rotating rod to rotate. The planar thread on the surface of the indexing plate drives the chuck tooth seat to move closer to the axis. Since the protrusion plate fixes the collet through the groove, it is convenient for the mechanism to clamp and lock the tool.

[0016] 2. This utility model provides a tool changing mechanism with a locking function. Activating the first electric telescopic rod causes the first limiting block to move laterally within the first sliding groove. Then, activating the second electric telescopic rod causes the second limiting block to move longitudinally on the second sliding groove, thereby adjusting the locking mechanism horizontally and vertically. Subsequently, activating the motor causes the first gear to rotate, which in turn causes the second gear to rotate. The second gear then causes the first movable rod to rotate on the support plate, thereby adjusting the angle of the locking mechanism. This allows the locking mechanism to precisely align with the tool, locking and clamping it for tool replacement. Attached Figure Description

[0023] The present invention will be further described in detail below with reference to embodiments:

[0024] Example 1

[0025] like Figure 1-5 As shown, this utility model provides a tool changing mechanism with locking function, including a movable adjustment component 1, a placement plate 2 is installed at one end of the movable adjustment component 1, a steering component 3 is installed on the surface of the placement plate 2, and a locking mechanism 4 is provided at one end of the steering component 3.

[0026] The locking mechanism 4 includes a housing 40 and an indexing plate 48. A motor 41 is mounted on one end of the housing 40. The output end of the motor 41 is fixedly connected to a connecting end 42. The interior of the connecting end 42 is connected to one end of a rotating rod 45. A ball head protrusion 43 is provided at the contact end between the rotating rod 45 and the connecting end 42. A spring 44 is connected to one end of the ball head protrusion 43. A bearing 46 is fixed to the outside of the rotating rod 45. A clamping housing 47 is provided at one end of the housing 40. A cylindrical groove 49 is provided inside the clamping housing 47. The indexing plate 48 is disposed inside the cylindrical groove 49. The side of the indexing plate 48... A planar thread 491 is provided. A chuck 494 is connected to the side of the indexing plate 48 near the planar thread 491. A toothed seat 495 is provided at one end of the chuck 494 connected to the planar thread 491. Grooves 492 are provided on both sides of the chuck 494. A protrusion plate 493 is connected to the inside of the groove 492 and the clamping housing 47. The internal cross-sectional shape of the connecting end 42 is set as a rounded square. The connecting end 42 and one end of the rotating rod 45 form a locking structure. There are two ball head protrusions 43. The ball head protrusions 43 form a locking structure with the connecting end 42 through the spring 44.

[0027] Specifically, when it is necessary to clamp and lock the tool, the adjusting component 1 and the steering component 3 are moved to the middle of the chuck 494, and then the motor 41 is energized to drive the rotating rod 45 to rotate on the bearing 46, which in turn drives the indexing plate 48 on the rotating rod 45 to rotate. The flat thread 491 on the surface of the indexing plate 48 drives the chuck tooth seat 495 of the chuck 494 to move closer to the axis. Since the protrusion plate 493 fixes the chuck 494 through the groove 492, the mechanism clamps and locks the tool. The angle between the chucks 494 is set to 120°, which can easily prevent the tool from deviating from the axis when clamping the tool. There are three chucks 494 in total, and the chucks 494 are distributed at 120° between them. The head 494 forms a threaded structure through the toothed seat 495 and the planar thread 491. The chucks 494 are arranged at 120° intervals to facilitate positioning the tool on the axis of the rotating rod 45 when clamping the tool. The end of the chuck 494 connected to the planar thread 491 is provided with a toothed seat 495. The two sides of the chuck 494 are provided with grooves 492. The inside of the grooves 492 and the clamping housing 47 are connected to a protruding plate 493. The protruding plate 493 is fixed to the clamping housing 47, and the protruding plate 493 and the groove 492 form an engaging structure. The engaging structure between the protruding plate 493 and the groove 492 can easily fix the chuck 494 and prevent it from shifting or loosening.

[0028] Example 2

[0029] like Figure 1-5As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the steering component 3 includes a support plate 30 and a second movable rod 34. The support plate 30 is fixedly connected to the surface of the placement plate 2. A motor 31 is fixedly connected to one side of the support plate 30. A first gear 35 is fixedly connected to the output end of the motor 31. A second gear 32 is meshed with one side of the first gear 35. A first movable rod 33 is fixedly connected to the surface of the second gear 32. The first movable rod 33 is movably connected inside the support plate 30. The second movable rod 34 is movably connected to the support plate 30. Inside 0, one end of the first movable rod 33 is fixedly connected to the outside of the locking mechanism 4. The movable adjustment component 1 includes a first sliding groove 10. A first electric telescopic rod 11 is fixedly connected inside the first sliding groove 10. A first limiting block 12 is fixedly connected to one end of the first electric telescopic rod 11. A second sliding groove 13 is fixedly connected to the upper end of the first limiting block 12. A second electric telescopic rod 15 is fixedly connected inside the second sliding groove 13. A second limiting block 14 is fixedly connected to one end of the second electric telescopic rod 15. A placement plate 2 is fixedly connected to the top of the second limiting block 14.

[0030] Specifically, when a tool needs to be replaced, the first electric telescopic rod 11 is activated, causing the first limiting block 12 to move laterally within the first sliding groove 10. Then, the second electric telescopic rod 15 is activated, causing the second limiting block 14 to move longitudinally on the second sliding groove 13, thereby adjusting the locking mechanism 4 both laterally and longitudinally. Subsequently, the motor 31 is activated, causing the first gear 35 to rotate. The first gear 35 then rotates the second gear 32, which in turn rotates the first movable rod 33 on the support plate 30, thereby adjusting the angle of the locking mechanism 4. This allows the locking mechanism 4 to be precisely aligned with the tool, locking and clamping it for replacement.

[0031] The working principle of this tool changer with locking function will be explained in detail below.

[0032] like Figure 1-5As shown, when a tool needs to be replaced, the first electric telescopic rod 11 is activated, causing the first limiting block 12 to move laterally within the first sliding groove 10. Then, the second electric telescopic rod 15 is activated, causing the second limiting block 14 to move longitudinally on the second sliding groove 13, thereby adjusting the locking mechanism 4 horizontally and vertically. Subsequently, the motor 31 is activated, causing the first gear 35 to rotate. The first gear 35 then rotates the second gear 32, which in turn rotates the first movable rod 33 on the support plate 30, thus adjusting the angle of the locking mechanism 4. This allows the locking mechanism 4 to precisely align with the tool and lock and clamp it for replacement. When a tool needs to be clamped and locked, the adjusting component 1 and the steering component 3 are moved to the center of the chuck 494. Then, the motor 41 is energized, causing the rotating rod 45 to rotate on the bearing 46, which in turn rotates the indexing plate 48 on the rotating rod 45. The flat thread 491 on the surface of the indexing plate 48 causes the chuck tooth seat 495 to move closer to the center of the chuck 494. The axial movement is achieved by fixing the collet 494 to the convex plate 493 via the groove 492, thus clamping and locking the tool. The angle between the collets 494 is set at 120°, which helps prevent the tool from deviating from the axial center when clamping it. There are three collets 494 in total, distributed at 120° intervals. The collets 494 form a threaded structure through the toothed seat 495 and the flat thread 491. The 120° distribution of the collets 494 facilitates tool clamping. The cutting tool is located on the axis of the rotating rod 45. One end of the collet 494 connected to the planar thread 491 is provided with a tooth seat 495. Grooves 492 are provided on both sides of the collet 494. A protruding plate 493 is connected to the inside of the groove 492 and the clamping housing 47. The protruding plate 493 and the clamping housing 47 are fixed, and the protruding plate 493 and the groove 492 form an engaging structure. By utilizing the engaging structure between the protruding plate 493 and the groove 492, the collet 494 can be easily fixed to prevent displacement and loosening.

[0033] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
