Description

Technical Field

[0001] This utility model relates to the field of cutting tool detection technology, specifically to an automatic cutting tool damage detection device. Background Technology

[0002] With the development of modern manufacturing, the cutting tool industry is also constantly progressing. Cutting tools are tools used for cutting and machining in mechanical manufacturing, also known as cutting tools. In order to ensure the production quality of cutting tools, the detection of tool wear and breakage is often set during the processing. The detection methods can detect the surface defects, cracks, wear and other conditions of the cutting tools in an all-round way to ensure the stability and durability of the cutting tools. At present, there are various automatic tool breakage detection devices available on the market, but there are still some shortcomings.

[0003] Existing automatic tool breakage detection devices use sensors to detect tools. However, during the detection process, the tool cannot be rotated, resulting in an inability to perform omnidirectional detection. Furthermore, while the detection device remains fixed during tool transport on a conveyor belt, the tool's position can shift, reducing the accuracy of the detection. For example, Chinese utility model patent CN217394490U discloses an automatic tool breakage detection device, including a tool base, a fixture base, a horizontal drive motor, a vertical drive motor, a longitudinal drive motor, and a proximity switch sensor. The tool base and fixture base are arranged opposite each other. A fixing block is set on the side, and a longitudinal drive motor is fixed on the fixing block. A longitudinal sliding block is slidably set on the tool base along the longitudinal direction. The output end of the longitudinal drive motor is connected to a longitudinal lead screw, which passes through the longitudinal sliding block. The longitudinal lead screw nut on the longitudinal lead screw is connected to the side wall of the longitudinal sliding block. A transverse sliding block is slidably connected to the upper surface of the longitudinal sliding block. A transverse drive motor is set on one side of the longitudinal sliding block. The output end of the transverse drive motor is connected to a transverse lead screw, which passes through the transverse sliding block. The transverse lead screw is helically sleeved on the transverse lead screw and connected to the side wall of the transverse sliding block. This utility model can detect tool wear and breakage in time, stop the machine in time to replace the tool, and avoid affecting the quality of processed products and production efficiency. However, this device has problems such as the detector being exposed to the air for a long time, accumulating a lot of dust, which will greatly shorten the service life of the detector. Therefore, we propose an automatic tool breakage detection device to solve the above-mentioned problems. Utility Model Content

[0004] The purpose of this utility model is to provide an automatic tool breakage detection device to solve the problems mentioned in the background art. The current automatic tool breakage detection devices cannot be rotated, which leads to the inability to fully detect the tool. At the same time, the tool will deviate during the conveyor belt transmission, which will lead to inaccurate detection. In addition, the detector will accumulate a lot of dust when exposed to the air for a long time, which will greatly shorten the service life of the detector.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic tool breakage detection device, comprising:

[0006] Conveyor belt, which is placed directly on the ground;

[0007] Also includes:

[0008] A fixed plate is provided with a flipping mechanism on its rear side. The flipping mechanism includes a rotating plate, a rotating disk, a lever, a rotating block, a motor, and an electric telescopic rod. The rotating plate is fixedly connected to the rear side of the fixed plate, and a rotating disk is installed on the rear side of the rotating plate. A rotating block is slidably connected to the outer side of the rotating disk. A lever is fixedly installed on the front side of the rotating block. A motor is connected to the rear side of the rotating block, and an electric telescopic rod is connected to the rear side of the motor.

[0009] The detector has a protective mechanism on its outer side, which includes a protective box, a sliding rod, a threaded rod, and a limiting rod. The protective boxes are symmetrically arranged on the front and rear sides of the detector. The sliding rod is fixedly installed on the outer side of the protective box. The sliding rod is internally threaded to the upper part of the sliding rod, and the outer end of the threaded rod is connected to a motor.

[0010] Preferably, support seats are provided at equal intervals above the conveyor belt, and a tool body is provided above the support seats.

[0011] Preferably, a fixing plate is tightly fitted to the rear outer side of the tool body, and a spring is fixedly connected to the outside of the fixing plate.

[0012] Preferably, a support plate is connected to the outer side of the spring, and the support plate is fixedly connected to the support base.

[0013] Preferably, a limit plate is symmetrically slidably arranged above the middle of the conveyor belt, and an electric telescopic rod is installed on the outer side of the limit plate.

[0014] Preferably, the lever is slidably connected to the rotating plate.

[0015] Preferably, a support frame is fixedly installed on the rear side of the middle section of the conveyor belt, and a hydraulic cylinder is fixedly installed on the front side above the support frame, and a detector is installed on the output end of the hydraulic cylinder.

[0016] Preferably, a collection box is provided on the front side of the middle section of the conveyor belt.

[0017] Preferably, a stabilizing plate is installed on the left front side of the conveyor belt, and a computer is installed above the stabilizing plate.

[0018] Preferably, a limiting rod is engaged above the sliding rod, and the limiting rod is located above the threaded rod.

[0019] Compared with the prior art, the beneficial effects of this utility model are: the automatic knife breakage detection device, by setting a flipping mechanism, allows the knife to rotate 360°, thereby enabling all-round detection of the knife. At the same time, a fixing mechanism is set to fix the detection position of the knife, thereby greatly improving the accuracy of knife detection. In addition, a protective mechanism is set to effectively protect the detector, thereby greatly extending the service life of the detector.

[0020] 1. It is equipped with a support base, a tool body, a fixing plate and a spring. The support base is set at equal distances above the conveyor belt, and the fixing plate is set on the rear side above the support base. The rear end of the tool body can be inserted into the interior of the fixing plate. Since the left and right sides of the outside of the fixing plate are fixedly connected to the spring, and the outside of the spring is connected to the support plate for support, and the spring has elasticity, the fixing plate can be tightly fitted to the outside of the tool body to fix and limit its position.

[0021] 2. Equipped with an electric telescopic rod and a limiting plate, the support seat can be transported above the conveyor belt by opening the conveyor belt. Since the limiting plates are symmetrically arranged on both the front and rear sides above the middle of the conveyor belt, and the electric telescopic rod is arranged on the outside of the limiting plate, the electric telescopic rod can be opened after the support seat is transported to the middle of the conveyor belt. This allows the output end of the electric telescopic rod to push the limiting plate inward. The limiting plate can fit tightly with the support seat located above the middle of the conveyor belt, which can fix the position of the support seat and facilitate better subsequent inspection of the tool body above the support seat.

[0022] 3. The device is equipped with a rotating plate, a rotating disk, a lever, and a rotating block. The rotating plate is connected to the rear end of the fixed plate, and the rotating disk is installed on the rear side of the rotating plate. After the support seat is moved to the middle of the conveyor belt and fixed, the electric telescopic rod connected to the rear of the motor can be opened. The output end of the electric telescopic rod can push the motor to move forward. Since the lever and rotating block are installed on the front side of the motor, the rotating block can be moved to fit against the outer side of the rotating disk. When the motor is turned on, the lever and rotating block will rotate. When the lever rotates, it will make sliding contact with the rotating plate, causing the rotating plate and rotating disk to rotate. When the rotating block rotates, it will make sliding contact with the outer side of the rotating disk, causing the rotating plate and rotating disk to pause rotation. That is, the rotating plate will rotate intermittently. When the rotating plate rotates, it can drive the fixed plate to rotate. When the fixed plate rotates, the tool body will rotate together. In this way, the detector can perform all-round inspection of the tool body.

[0023] 4. Equipped with a testing instrument, computer, and stabilizing plate, the testing instrument is used to inspect the tool body. The testing instrument is wirelessly connected to the computer, and a stabilizing plate is installed below the computer for support. This allows the operator to better observe the inspection status of the tool body using the computer.

[0024] 5. The device is equipped with a protective box, a sliding rod, a threaded rod, and a limiting rod. The protective box is located on the front and rear sides of the detector. When the detector is not in use, the protective box provides effective protection. The sliding rod is installed on the outside of the protective box, and its upper part is threadedly connected to the threaded rod. The upper part of the sliding rod is also engaged with the limiting rod. When the detector is in use, the motor connected to the outer end of the threaded rod can be turned on, causing the threaded rod to rotate. At this time, the sliding rod will move on the outside of the threaded rod. When the sliding rod moves outward, the protective box will disengage from the outside of the detector, and the detector can then be used. Attached Figure Description

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Please see Figures 1-7 This utility model provides a technical solution:

[0035] Example 1: To address the problems existing in the prior art, this example provides the following technical solution: an automatic tool breakage detection device, comprising a conveyor belt 1; a flipping mechanism located on the rear side of a fixed plate 4, allowing the fixed plate 4 to rotate the tool body 3 held in place 360°, thus enabling all-around detection of the tool body 3; a fixing mechanism located above and outside a support base 2, which securely clamps the tool body 3 and fixes the position of the support base 2 during tool body 3 detection, greatly improving the accuracy of tool body 3 detection; and a protective mechanism located outside a detector 14, which, when the device is not in use, allows a protective box 20 to protect the detector 14.First, insert the rear end of the tool body 3 into the interior of the fixing plate 4 installed on the rear side above the support base 2. Since the outer side of the fixing plate 4 is connected to a spring 5, and the outer side of the spring 5 is connected to the support plate 6 for support, the spring 5 has elasticity, meaning the fixing plate 4 can firmly clamp and fix the tool body 3. At this time, open the conveyor belt 1, so the support base 2 can be transported above the conveyor belt 1. When the support base 2 moves to the middle of the conveyor belt 1, open the electric telescopic rod 12 connected to the outer end of the limiting plate 13. The output end of the electric telescopic rod 12 can push the limiting plate 13 inward to clamp and fix the support base 2 that has moved to the middle. Then, open the electric telescopic rod 12 connected to the rear end of the motor 11. The electric telescopic rod 12 can push the motor 11 to move forward. Since the output shaft of the motor 11 is equipped with a lever 9 and a rotating block 10, the lever 9 and the rotating block 10 can move forward until the rotating block 10 is in contact with the rotating disk 8 installed on the rear side of the fixed plate 4. At the same time, a rotating plate 7 is installed on the front side of the rotating disk 8. When the motor 11 is opened, the lever 9 and the rotating block 10 will rotate. When the lever 9 rotates, it will cause the rotating plate 7 to rotate. When the rotating block 10 rotates, it will make sliding contact with the outer side of the rotating disk 8, causing the rotating disk 8 to stop rotating. This allows the rotating plate 7 to intermittently rotate the fixed plate 4. Since the tool body 3 is located on the front side of the fixed plate 4, it also rotates. At this time, the hydraulic cylinder 15 mounted above the detector 14 is activated. The support frame 16 is connected above the hydraulic cylinder 15 for support. The output end of the hydraulic cylinder 15 can push the detector 14 downwards to perform a comprehensive inspection of the rotating tool body 3. Since the detector 14 is wirelessly connected to the computer 17, and a stabilizing plate 18 is installed below the computer 17 for support, the operator can more clearly observe the tool body 3 through the computer 17. If any damage is found... When the tool body 3 is damaged, it can be removed and placed inside the collection box 19. After use, the motor 11 connected to the external threaded rod 22 can be turned on, causing the threaded rod 22 to rotate. Since the outer thread of the threaded rod 22 is threadedly connected to the sliding rod 21, and the upper part of the sliding rod 21 is engaged with the limiting rod 23, the sliding rod 21 will slide on the outer side of the threaded rod 22. A protective box 20 is installed on the inner side of the lower part of the sliding rod 21. When the sliding rod 21 slides inward, the protective box 20 will also move along with it, moving to the outside of the detector 14 to protect it.

[0036] Existing detection devices cannot rotate the tool body 3, resulting in incomplete detection of the tool body 3. Therefore, this embodiment adopts the following technical solution, such as... Figure 3 , Figure 6 and Figure 7As shown, the flipping mechanism includes a fixed plate 4, with a rotating plate 7 connected to the rear end of the fixed plate 4. A rotating disk 8 is installed on the rear side of the rotating plate 7. After the support base 2 is moved to the middle of the conveyor belt 1 and fixed, the electric telescopic rod 12 connected to the rear side of the motor 11 can be turned on. The output end of the electric telescopic rod 12 can push the motor 11 to move forward. Since the lever 9 and the rotating block 10 are installed on the front side of the motor 11, the rotating block 10 can be moved to the outside of the rotating disk 8 for contact. When the motor 11 is turned on, the lever 9 and the rotating block 10 can rotate. When the lever 9 rotates, it will make sliding contact with the rotating plate 7, which will cause the rotating plate 7 and the rotating disk 8 to rotate. When the rotating block 10 rotates, it will make sliding contact with the outside of the rotating disk 8, which will cause the rotating plate 7 and the rotating disk 8 to pause rotation. That is, the rotating plate 7 will rotate intermittently. When the rotating plate 7 rotates, it can drive the fixed plate 4 to rotate. When the fixed plate 4 rotates, the tool body 3 will rotate together. In this way, the detector 14 can perform all-round detection on the tool body 3.

[0037] Example 2: In existing detection devices, the tool body 3 may shift during transport on the conveyor belt 1, leading to inaccurate detection. Therefore, this example addresses this issue by employing the following technical solution: Figure 1 , Figure 2 and Figure 3 As shown, the fixing mechanism includes a fixing plate 4 set above the support base 2. The rear end of the tool body 3 can be inserted into the fixing plate 4. Since springs 5 ​​are fixedly connected to the left and right sides of the outside of the fixing plate 4, and the outside of the springs 5 ​​is connected to the support plate 6 for support, and the springs 5 ​​have elasticity, the fixing plate 4 can fit tightly against the outside of the tool body 3 to fix and limit its position. At the same time, when the support base 2 is transmitted to the middle of the conveyor belt 1, the electric telescopic rod 12 can be opened, so that the output end of the electric telescopic rod 12 pushes the limiting plate 13 inward. The limiting plate 13 can fit tightly against the support base 2 located above the middle of the conveyor belt 1, which can fix the position of the support base 2, making it easier to detect the tool body 3 above the support base 2 later.

[0038] Example 3: Existing detection devices, such as the detector 14, suffer from problems such as accumulating a large amount of dust when exposed to air for extended periods, which significantly shortens the lifespan of the detector 14. Therefore, this example addresses these issues through the following technical solution: Figure 1 , Figure 4 and Figure 5As shown, the protective mechanism includes a protective box 20 symmetrically arranged on the front and back of the detector 14. When the detector 14 is not in use, the protective box 20 can effectively protect the detector 14. Since a sliding rod 21 is installed on the outside of the protective box 20, the upper part of the sliding rod 21 is threadedly connected to the threaded rod 22, and the upper part of the sliding rod 21 is engaged with the limiting rod 23. That is, when the detector 14 is in use, the motor 11 connected to the outer end of the threaded rod 22 can be opened to make the threaded rod 22 rotate. At this time, the sliding rod 21 will move on the outside of the threaded rod 22. When the sliding rod 21 moves outward, the protective box 20 will disengage from the outside of the detector 14, and the detector 14 can be used.
