[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0034] Please refer to Figures 1 - 4 , a tool connection degree detection device for a machine tool, including a machine tool body 1. An installation support plate 2 is fixedly installed on the upper surface of the machine tool body 1. A connection block 3 is fixedly installed at the top end inside the installation support plate 2. A tool body 4 is fixedly installed on the bottom surface of the connection block 3. A testing mechanism 29 is provided at the top end inside the installation support plate 2. An installation plate 5 is fixedly connected to a position near one side at the top end inside the installation support plate 2. A control module 6 and an indicator light 7 are fixedly installed on the outer side wall of the installation plate 5. A laser sensor 8 is installed on the back surface of the installation plate 5. A protection mechanism 30 is provided on the outer side wall of the machine tool body 1. The testing mechanism 29 includes a ring-shaped bearing plate 10. The ring-shaped bearing plate 10 is arranged directly below the tool body 4. Two groups of brackets 9 are fixedly connected to the outer side wall of the ring-shaped bearing plate 10. And both ends of the two groups of brackets 9 away from the ring-shaped bearing plate 10 are fixedly connected to the top end inside the installation support plate 2.

[0035] A ring-shaped movable plate 11 is movably installed above the ring-shaped bearing plate 10. A ring groove 19 is opened on the upper surface of the ring-shaped bearing plate 10. A plurality of groups of slide bars 20 are inserted into the ring groove 19. And the upper ends of the plurality of groups of slide bars 20 are all fixedly connected to the ring-shaped movable plate 11. An annular limiting groove is opened on the inner side wall of the ring groove 19. A plurality of groups of limiting movable blocks are inserted into the annular limiting groove. And one ends of the plurality of groups of limiting movable blocks are respectively fixedly connected to the plurality of groups of slide bars 20. The slide bars 20 move along the ring groove 19 following the ring-shaped movable plate 11, which can make the ring-shaped movable plate 11 more stable when rotating. Among them, the limiting movable blocks move along the annular limiting groove following the slide bars 20, which can limit the position of the bottom of the slide bars 20, avoid disengaging from the ring groove 19, and further avoid the ring-shaped movable plate 11 disengaging from the ring-shaped bearing plate 10.

[0036] On the outer side wall of the annular bearing plate 10, a connecting block 12 is fixedly installed. On the upper surface of the connecting block 12, a rotating shaft 13 is rotatably connected. At the upper end of the rotating shaft 13, a gear 14 is fixedly connected. At the bottom surface of the connecting block 12, a motor is installed, and the output end of the motor is connected to one end of the rotating shaft 13. On the outer wall of the annular movable plate 11, a number of groups of tooth grooves are provided, and the number of groups of tooth grooves is engaged with the gear 14. By driving the rotating shaft 13 to rotate clockwise by the motor installed at the bottom surface of the connecting block 12 and cooperating with the tooth grooves, the annular movable plate 11 can be driven to rotate counterclockwise by 90°.

[0037] On the upper surface of the annular movable plate 11, a support plate 15 is fixedly installed. On the outer side wall of the support plate 15, a first electric telescopic rod 16 is installed. One end of the first electric telescopic rod 16 is fixedly connected to a connecting plate 17. On the upper end of the connecting plate 17, an arc-shaped test plate 18 is fixedly installed. The inner side wall of the arc-shaped test plate 18 is closely attached to the outer wall of the tool body 4. Driven by the first electric telescopic rod 16, the tool body 4 can be pushed to perform the connection degree test.

[0038] The output end of the laser sensor 8 is electrically connected to the input end of the control module 6, and the output end of the control module 6 is electrically connected to the input end of the indicator light 7.

[0039] When the machine tool is in use, the connection degree of the tool body 4 can be regularly detected by a detection device. During the detection, first, the electric telescopic rod 16 installed on the support plate 15 drives the connecting plate 17 to move towards the tool body 4, driving the arc-shaped test plate 18 to push and test the tool body 4. Then, the motor installed on the bottom surface of the connecting block 12 drives the rotating shaft 13 to rotate clockwise. Cooperating with the tooth grooves, it can drive the annular movable plate 11 to rotate counterclockwise by 90°. And the slide rod 20 follows the annular movable plate 11 to move along the annular groove 19, which can make the annular movable plate 11 more stable when rotating. Among them, the limit movable block follows the slide rod 20 to move along the annular limit groove, which can limit the position of the bottom of the slide rod 20 and prevent it from disengaging from the annular groove 19, thereby avoiding the annular movable plate 11 from disengaging from the annular bearing plate 10. Thus, it can drive the arc-shaped test plate 18 to rotate counterclockwise by 90° with the tool body 4 as the central axis and move to the other side position of the tool body 4. At this time, similarly, the electric telescopic rod 16 can drive the arc-shaped test plate 18 to move towards the tool body 4 again to conduct a push test in another direction. Similarly, the gear 14 can continue to cooperate with the tooth grooves to drive the annular movable plate 11 to rotate counterclockwise by 90° again and conduct a push test, so as to conduct push tests in all directions of the tool body 4, making the test of the tool body 4 more comprehensive and the test effect better. And during this process, the laser sensor 8 continuously senses the position of the tool body 4. When the tool body 4 falls off from the connection block 3 during the test, and the laser sensor 8 can no longer sense the position of the tool body 4, it transmits the information to the control module 6. The control module 6 controls the indicator light 7 to light up, which can prompt the staff that the tool has fallen off and stop the machine for timely maintenance, completing the detection operation of the tool connection degree on the machine tool body 1;

[0040] Among them, the model of the laser sensor 8 is IX-055.

[0041] Please refer to Figure 1 and Figure 4, the protection mechanism 30 includes an L-shaped fixing plate 21. Two groups of second electric telescopic rods 22 are installed near the upper end of the inner side wall of the L-shaped fixing plate 21. One end of each of the two groups of second electric telescopic rods 22 is fixedly installed with a fixing block 24. A bearing box 23 is fixedly installed between the outer side walls of the two fixing blocks 24. A buffer circular plate 28 is movably installed inside the bearing box 23. A number of telescopic push rods 25 are fixedly installed at the bottom end inside the bearing box 23, and one end of each of the number of telescopic push rods 25 is fixedly connected to the buffer circular plate 28. Buffer springs are sleeved outside the number of telescopic push rods 25. A number of sliding grooves 27 are formed in the inner side wall of the bearing box 23. Sliders 26 are inserted into the number of sliding grooves 27, and one end of each of the number of sliders 26 away from the sliding grooves 27 is fixedly connected to the buffer circular plate 28. When the tool body 4 falls off during the detection, it can be in the bearing box 23 under the action of gravity, avoiding the tool body 4 from falling off and rolling around on the machine tool body 1, which may affect the safety of the staff.

[0042] Specifically, during the detection operation, the two groups of second electric telescopic rods 22 installed on the L-shaped fixing plate 21 can drive the bearing box 23 connected by the two fixing blocks 24 to move to a position directly below the tool body 4. When the tool body 4 falls off during the detection, under the action of gravity, it can fall into the bearing box 23 in the protection mechanism 30 and contact the buffer circular plate 28. The impact force during the fall causes the buffer circular plate 28 to move downward along the sliding groove 27 through the slider 26, shortening the telescopic push rod 25 and compressing the buffer spring. Then, under the elastic force of the buffer spring, the telescopic push rod 25 elongates, driving the buffer circular plate 28 to move upward. Thus, the impact force when the tool body 4 falls can be well buffered, avoiding hitting the surface of the machine tool body 1 and causing secondary damage, and also avoiding the tool body 4 from falling off and rolling around on the machine tool body 1, which may affect the safety of the staff, making the detection work safer.

The general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present utility model.
