Description

Technical Field

[0001] This utility model belongs to the field of broken knife detection technology, and more specifically, it relates to an external broken knife detection mechanism. Background Technology

[0002] In the processing of automotive parts, CNC machine tools and machining centers are the most common production equipment. During the processing, the cutting tools of these machine tools are subjected to huge cutting forces and vibrations, which can easily lead to tool breakage. Once the tool breaks, it will not only scrap the workpiece, but may also damage the machine tool equipment. Therefore, it is necessary to check the condition of the tool in a timely manner.

[0003] For example, Chinese utility model patent No. 201721288402.1 provides a broken tool detection device. This detection device uses a mounting plate, a cylinder, a clamping plate and a photoelectric sensor. In use, a cylinder is set at the bottom of the mounting plate, and a clamping plate is set at the bottom of the cylinder. By activating the cylinder, the clamping plate is lowered, causing the photoelectric sensor on the clamping plate to fall down and touch the tool tip to detect the tool. However, traditional detection devices are usually directly installed on machine tools, and not all machine tools have reserved installation positions, resulting in a lack of applicability. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides an external broken tool detection mechanism. This addresses the issue that traditional detection devices are typically installed directly on machine tools, and not all machine tools have reserved installation locations, leading to a lack of applicability.

[0005] The purpose and effectiveness of this utility model's external broken knife detection mechanism are achieved through the following specific technical means:

[0006] An external broken knife detection mechanism includes a device box. One end of the device box is connected to a mounting plate via an adjustment assembly. A photoelectric sensor is installed at the bottom of the mounting plate. An audible and visual alarm is installed at the other end of the device box. The adjustment assembly includes a servo motor and a first electric telescopic rod. A first mounting slot is provided on one side of the device box, and the servo motor is installed in the first mounting slot. A through hole is provided at one end of the device box. One end of a rotating rod passes through the through hole and is connected to the main shaft of the servo motor. The other end is connected to the first electric telescopic rod, which is arranged perpendicular to the rotating rod. A moving assembly is provided at the bottom of the device box, and the moving assembly includes a second electric telescopic rod. The second electric telescopic rod is located at the bottom of the device box.

[0007] In a preferred embodiment, the adjustment assembly further includes a connecting plate, and a mounting slot is provided at the end of the rotating rod away from the servo motor. One end of the connecting plate is fixedly connected to the mounting slot by screws; the first electric telescopic rod is provided at the bottom of the connecting plate.

[0008] In a preferred embodiment, the bottom of the first electric telescopic rod is connected to the mounting plate, the top of the mounting plate has a mounting hole, and the photoelectric sensor passes through the mounting hole; the bottom of the mounting plate also has multiple sets of threaded holes, and multiple sets of anti-collision rods are connected to the multiple sets of threaded holes respectively through the studs at the top, and each set of anti-collision rods has an anti-collision terminal at its bottom.

[0009] In a preferred embodiment, the movable component further includes multiple sets of universal wheels with brakes, the bottom end of the second electric telescopic rod is connected to a mounting base, and fixed seats are provided on both sides of the mounting base. Both sets of fixed seats are fixedly connected to the top of the base plate by screws, and multiple sets of universal wheels with brakes are installed on the bottom of the base plate.

[0010] In a preferred embodiment, the top of the device box has a second mounting slot, in which a control module is disposed. The top of the device box has a rotating seat, and a rotatable protective cover is connected to the rotating seat corresponding to the second mounting slot via a shaft pin. The control module is located inside the protective cover.

[0011] In a preferred embodiment, the control module is provided with an antenna, one end of the protective cover has a compatibility slot corresponding to the antenna, the top of the device box has two sets of first slots, the bottom of the protective cover has two sets of locking posts corresponding to the two sets of first slots, and the two sets of locking posts are detachably inserted into the two sets of first slots; the end of the protective cover away from the rotating seat has a handle slot.

[0012] In a preferred embodiment, two sets of sliding grooves are provided at the opening of the first mounting groove, and the side baffle is slidably connected to the two sets of sliding grooves by multiple sets of sliders. Two sets of second slots are provided on the inner wall of the first mounting groove, and a locking block is provided at one end of the side baffle corresponding to the two sets of second slots. The two sets of locking blocks are detachably locked in the two sets of second slots.

[0013] In a preferred embodiment, multiple sets of ventilation slots are provided on the side of the side baffle corresponding to the equipment box, and the multiple sets of ventilation slots are all connected to the first mounting slot.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. By adjusting the component settings, when using this mechanism, the servo motor can be activated to drive the rotating rod to rotate. The first electric telescopic rod is arranged perpendicular to the rotating rod, and its extension and retraction can change the position of the mounting plate in the vertical direction, thereby adjusting the height and angle of the photoelectric sensor; this allows the detection mechanism to adapt to the position of the tool on different machine tools, improving its versatility.

[0016] 2. By setting up the moving components, when using this mechanism, the mechanism can be moved to the detection position by multiple sets of universal casters with brakes at the bottom of the base plate. After being moved into place, it can be kept stable by the braking function. This solves the problem of poor applicability of traditional detection mechanisms due to the lack of reserved installation positions on machine tools. It is easy to move and arrange, and improves the flexibility of use.

[0017] 3. With the protective cover, the control module on the top of the equipment box is protected when using the mechanism. The protective cover is connected to the rotating seat via a pivot pin and can be rotated. The compatibility slot at one end of the protective cover provides space for the antenna of the control module, ensuring that signal transmission is not affected. The side baffle and the ventilation slot on the equipment box ensure good heat dissipation of the servo motor in the first mounting slot, reducing failures caused by environmental factors and improving stability.

[0024] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0025] Example:

[0026] As attached Figure 1 To be continued Figure 4 As shown:

[0027] This utility model provides an external broken tool detection mechanism, including a device box 11. One end of the device box 11 is connected to a mounting plate 12 via an adjustment component. A photoelectric sensor 13 is installed at the bottom of the mounting plate 12. The photoelectric sensor 13 can be the E3FA model from the Zhican brand, used for real-time monitoring of the tool's working status. The other end of the device box 11 is equipped with an audible and visual alarm 18. The audible and visual alarm 18 can be the LTE-5060 model from the Donglan Electric brand, which can promptly issue an alarm once a broken tool is detected, minimizing losses caused by the broken tool. Adjustment... The component includes a servo motor 21 and a first electric telescopic rod 22. A first mounting slot 14 is provided on one side of the equipment box 11, where the servo motor 21 is installed. A through hole is provided at one end of the equipment box 11. One end of the rotating rod 23 passes through the through hole and is connected to the spindle of the servo motor 21. The other end is connected to the first electric telescopic rod 22. By starting the servo motor 21, the rotating rod 23 can be driven to rotate. The first electric telescopic rod 22 is arranged perpendicular to the rotating rod 23. Its extension and retraction can change the position of the mounting plate 12 in the vertical direction to adapt to the specific position of the tool on different machine tools, thereby improving versatility.

[0028] Please see as follows Figure 2 As shown, the adjustment assembly also includes a connecting plate 24. The end of the rotating rod 23 away from the servo motor 21 is provided with a mounting slot 25. One end of the connecting plate 24 is fixedly connected to the mounting slot 25 by screws. The bottom of the connecting plate 24 is equipped with a first electric telescopic rod 22.

[0029] Please see as follows Figure 2 and Figure 3 As shown, the bottom of the first electric telescopic rod 22 is connected to the mounting plate 12. The top of the mounting plate 12 has a mounting hole 27, through which the photoelectric sensor 13 is installed so that it can directly monitor the working status of the tool. In addition, the bottom of the mounting plate 12 also has multiple sets of threaded holes 28, and multiple sets of anti-collision rods 29 are connected to these threaded holes 28 through studs at the top. The bottom of each of these anti-collision rods 29 is provided with an anti-collision terminal 291, which plays a role in buffer protection. In the event of an accidental collision between the detection device and the machine tool, these anti-collision terminals 291 can absorb the impact force and prevent the photoelectric sensor 13 from being damaged.

[0030] Please see as follows Figure 4 As shown, a movable component is also provided at the bottom of the equipment box 11. The movable component includes multiple sets of universal casters 32 with brakes. A second electric telescopic rod 31 is provided at the bottom of the equipment box 11. The bottom end of the second electric telescopic rod 31 is connected to a mounting base 33. Fixed seats 34 are provided on both sides of the mounting base 33. These two sets of fixed seats 34 are fixed to the top of the base plate 35 with screws. Multiple sets of universal casters 32 with brakes are installed at the bottom of the base plate 35. This allows the entire testing device to move flexibly to the required testing position. After moving into position, the device can be fixed and kept stable by means of the universal casters 32 with brakes. In this way, it is no longer necessary to fasten it to the machine tool itself, which improves the flexibility of use and solves the problem of poor applicability of traditional testing mechanisms due to the lack of reserved installation positions on the machine tool, thus enhancing versatility.

[0031] Please see as follows Figure 2 and Figure 4 As shown, a second mounting slot 41 is provided on the top of the equipment box 11 for installing the control module 42. The control module 42 can be the LR151 model from the Xiaoma IoT brand. The photoelectric sensor 13 and the audible and visual alarm 18 are both electrically connected to the control module 42. When the photoelectric sensor 13 detects that the tool is working normally and there is no damage, the control module 42 will not trigger the audible and visual alarm 18 and will remain silent. However, once the photoelectric sensor 13 detects that the tool is broken or otherwise damaged, the control module 42 will immediately activate the audible and visual alarm 18 and issue a conspicuous audible and visual alarm signal. This can promptly remind the operator to pay attention and avoid the consequences caused by the broken tool.

[0032] Please see as follows Figure 4 As shown, the top of the device box 11 is also provided with a rotating base 43. A rotatable protective cover 44 is connected to this rotating base 43 by a shaft pin. The control module 42 is installed inside the protective cover 44, and an antenna is provided above the control module 42 for wireless signal transmission. One end of the protective cover 44 has a compatibility slot 45 corresponding to the antenna, which provides sufficient space for the antenna of the control module 42. In addition, the top of the device box 11 also has two sets of first slots, and the bottom of the protective cover 44 has two sets of locking posts 46 corresponding to these two sets of slots. These locking posts 46 can be detachably inserted into the two sets of first slots to fix the protective cover 44. The end of the protective cover 44 away from the rotating base 43 also has a handle slot 47, which allows the user to open or close the protective cover 44 by rotating it for maintenance and inspection of the control module 42.

[0033] Please see as follows Figure 2 and Figure 4As shown, two sets of sliding grooves 15 are provided at the opening of the first mounting groove 14. The side baffle 16 is slidably connected to these two sets of sliding grooves 15 by multiple sets of sliders. At the same time, two sets of second slots are also provided on the inner wall of the first mounting groove 14. One end of the side baffle 16 is provided with a locking block corresponding to these two sets of slots. These two sets of locking blocks are detachably locked in the second slots, further reinforcing the fixation of the side baffle 16. This sliding and locking structure not only ensures that the side baffle 16 can be stably installed at the opening of the first mounting groove 14, but also allows for sliding switching, which is convenient for users to maintain. In addition, multiple sets of ventilation grooves 17 are provided on the side of the side baffle 16 corresponding to the equipment box 11. These ventilation grooves 17 are all connected to the first mounting groove 14, which realizes good heat dissipation of the servo motor 21 in the first mounting groove 14, reduces failures caused by environmental factors, and improves stability.
