Description

Technical Field

[0001] The present application relates to the technical field of pin production, and in particular to a track pin detection device. Background Art

[0002] Tracks are usually used on engineering vehicles or military vehicles. They have high passability and strong grip, and do not have too many requirements for the use environment. The track is driven by the driving wheel and is a flexible chain link surrounding the driving wheel, road wheel, idler wheel and track roller. The track is composed of track shoes and track pins. The track pins connect the track shoes to form a track chain link.

[0003] Tracks mainly include two types: metal pin hinge type and metal rubber hinge type. Since the pin shaft needs to withstand a large shear force during the operation of the track, in order to ensure the safety of the track during operation, the relevant technicians will conduct various tests on the pin shaft before leaving the factory.

[0004] At present, inspectors mostly use sampling method to detect points on the outer wall of the pin shaft with handheld inspection tools. This method has low inspection efficiency and poor representativeness of data, which affects workers' judgment. Summary of the Invention

[0006] To this end, one purpose of the present application is to propose a track pin shaft detection device that is suitable for various survey methods such as census and sampling, has high detection efficiency and high accuracy of detection results.

[0008] The crawler pin shaft detection device of the embodiment of the present application sets up a feeding mechanism to push multiple completed pin shafts into the detection mechanism in sequence. The pin shaft with abnormal external shape will apply unbalanced external force to the detection roller after rotation. This external force is sensed by the pressure sensing film, thereby realizing the detection of the straightness of the pin shaft. At the same time, the infrared detection device is used to detect possible cracks on the pin shaft, so that the pin shaft detection result is highly accurate. In addition, the device can detect multiple pin shafts at the same time.

DETAILED DESCRIPTION

[0026] The following describes in detail embodiments of the present application, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0027] The track pin detection device according to an embodiment of the present application will be described below with reference to the accompanying drawings.

[0028] The track pin shaft detection device provided in this application is mainly used in pin shaft production factories. After the pin shaft production is completed, the pin shaft is inspected by this device, which can prevent defective products from entering the market and ensure the dimensional accuracy of the pin shaft and the assembly accuracy during the installation process.

[0029] like Figure 1-Figure 3 As shown, the track pin shaft detection device of the embodiment of the present application may include a detection platform 1, a feeding mechanism 2, a detection mechanism 3, a driving device 4, an infrared detection device 5 and a control box 6.

[0030] Among them, the testing platform 1 is placed perpendicular to the ground, the feeding mechanism 2, the testing mechanism 3, the driving device 4, the infrared detection device 5 and the control box 6 are respectively arranged on the testing platform 1, and the feeding mechanism 2 is arranged on one side of the testing mechanism 3. The feeding mechanism 2 is used to provide the pin shaft to be tested to the testing mechanism 3.

[0031] It is understandable that the feeding mechanism 2 can push multiple pins toward the detection mechanism 3 in sequence and at intervals, which can avoid the pins from generating excessive impact force when entering the detection mechanism 3, thereby avoiding damage to the detection roller 32 and extending the service life of the detection roller 32.

[0032] The detection mechanism 3 may include two detection rollers 32 , wherein the detection rollers 32 are used to detect the straightness of the pin shaft. The detection rollers 32 may include a roller shaft 321 , a rubber layer 322 , a pressure-sensitive film 323 and a protective layer 324 .

[0033] The rubber layer 322 is wrapped around the outside of the roller 321 , and the pressure-sensing film 323 is wrapped around the outside of the rubber layer 322 . The pressure-sensing film 323 is used to sense the force acting on the two detection rollers 32 when the pin shaft rotates. The protective layer 324 is wrapped around the outside of the pressure-sensing film 323 .

[0034] It should be noted that the material of the protective layer 324 described in this embodiment is made of polylactic acid, which has a smooth surface and has a certain hardness and can change its shape according to the shape of the pin to be detected.

[0035] In the embodiment of the present application, the rubber layer 322 not only serves as an insulator, but also, when the pin shaft with an abnormal external shape rotates and causes the pressure sensing film 323 to be concave, the rubber layer 322 can use its own elastic potential energy to quickly restore the concave portion of the pressure sensing film 323.

[0036] The driving device 4 is used to drive the two detection rollers 32 to rotate, thereby driving the pin shaft to rotate. The infrared detection device 5 is located below the two detection rollers 32. The infrared detection device 5 is used to detect cracks on the pin shaft and monitor the working status of the detection roller 32. The feeding mechanism 2, the detection mechanism 3, the driving device 4 and the infrared detection device 5 are respectively connected to the control box 6.

[0037] It should be noted that the driving device 4 described in this embodiment includes a servo motor (not specifically marked in the figure), multiple pulleys (not specifically marked in the figure) and multiple belts (not specifically marked in the figure). The servo motor drives the two detection rollers 32 to rotate through the transmission connection between the belts and the pulleys.

[0038] In the embodiment of the present application, external mains electricity is used to power the feeding mechanism 2, the detection mechanism 3, the driving device 4, the infrared detection device 5 and the control box 6 in the device.

[0039] Specifically, when using this device to detect pins in a pin production factory, first, start the device, and the feeding mechanism 2, detection mechanism 3, drive device 4, infrared detection device 5 and control box 6 start to operate. Use an external robotic arm (not shown in the figure) to place multiple pins on the feeding mechanism 2, and the feeding mechanism 2 slowly pushes the pins into the interior of the detection mechanism 3 one by one.

[0040] The driving device 4 drives the two detection rollers 32 to rotate in the same direction, thereby driving the multiple pins to rotate between the two detection rollers 32 at the same time.

[0041] During detection, the pin rotates. Under the action of gravity, the force exerted by the pin on the two detection rollers 32 is stable. The pressure sensing film 323 senses this force and transmits the detection data to the control box 6 in real time. It can be understood that a signal transceiver module (not shown in the figure) is also provided inside the detection roller 32, and the signal transceiver module is connected to the control box 6 wirelessly.

[0042] If the straightness of the pin is poor or there is an abnormal protrusion on the pin, the pin itself does not rotate on the same axis, and the force exerted by the pin on the detection roller 32 is unstable or abnormal. The pressure sensing film 323 measures this force and transmits the detection data to the control box 6 in real time.

[0043] If there is an abnormal protrusion on the pin shaft, the pin shaft will exert a force on the protective layer 324 and the pressure sensing film 323 during the rotation process, causing the protective layer 324 and the pressure sensing film 323 to become concave. When this abnormal protrusion is removed, the rubber layer 322 can restore the concave through its own elastic potential energy, ensuring that the pressure sensing film 323 returns to its original shape, thereby ensuring the accuracy of the detection data.

[0044] At the same time, the infrared detection device 5 detects cracks on the pin below. As the pin continues to rotate, the entire pin is fully inspected and the inspection results are fed back to the control box 6. The infrared detection device 5 can also monitor the working status of the inspection roller 32. If the rubber layer 322 does not restore the pressure-sensitive film 323 to its original state during the pin inspection process, the infrared detection device 5 can send a warning signal to the control box 6. This device can inspect multiple pins simultaneously, and the pins move autonomously after the inspection is completed, making it suitable for various survey methods such as censuses and sampling, and has high inspection efficiency.

[0045] If abnormal data is detected by this device, workers can pick out the pins with abnormal data, thereby preventing products that do not meet technical requirements from entering the market and ensuring the dimensional accuracy of the pins and the assembly accuracy during the installation process.

[0046] As the feeding mechanism 2 pushes the plurality of pins into the interior of the detection mechanism 3 in sequence, the pins that have completed detection can be temporarily stored in an external collection box (not shown in the figure) for convenient unified processing later.

[0047] In one embodiment of the present application, Figure 4 As shown, the feeding mechanism 2 may include a conveying assembly 21 , and the conveying assembly 21 may include two baffles 211 , a plurality of brackets 212 , a conveying belt 213 and a driving motor 214 .

[0048] Among them, one end of multiple brackets 212 is respectively connected to the corresponding baffles 211, and the other ends of the brackets 212 are respectively set on the detection platform 1, the conveyor belt 213 is installed between the two baffles 211, and the drive motor 214 is installed on one side of a baffle 211, and the output shaft of the drive motor 214 is connected to the pulley of the conveyor belt 213.

[0049] In one embodiment of the present application, Figure 5 As shown, the feeding mechanism 2 may further include a material shifting assembly 22 , which may include a mounting plate 221 , two first cylinders 222 , two connecting plates 223 and two second cylinders 224 .

[0050] Among them, the mounting plate 221 is movably arranged above the two baffles 211, the two first cylinders 222 are arranged on the mounting plate 221, the two connecting plates 223 are symmetrically arranged on the mounting plate 221, one end of the two second cylinders 224 is respectively connected to the corresponding connecting plates 223, and the other end of the two second cylinders 224 is respectively connected to one side of the corresponding baffle 211.

[0051] In one embodiment of the present application, Figure 4 and Figure 5 As shown, a limiting groove 230 is provided on the baffle 211 , and two limiting rods 231 are symmetrically provided on the mounting plate 221 . The limiting rods 231 are slidably disposed inside the limiting groove 230 .

[0052] Specifically, after the pin shaft to be inspected is placed on the conveyor belt 213 by using an external robotic arm, the drive motor 214 is operated, and the drive motor 214 drives the conveyor belt 213 to rotate, thereby driving the pin shaft to be inspected to move.

[0053] One first cylinder 222 is retracted, and the other first cylinder 222 is extended, thereby temporarily retaining the pin shaft on the conveyor belt 213. After the pin shaft inspection on the detection mechanism 3 is completed, one first cylinder 222 is extended, and the other first cylinder 222 is retracted. At the same time, the two second cylinders 224 are extended at the same time, thereby pushing the mounting plate 221 to move. The mounting plate 221 drives the limiting rod 231 to move inside the limiting groove 230, thereby limiting the mounting plate 221. The mounting plate 221 drives the two first cylinders 222 to move, thereby pushing the pin shaft into between the two detection rollers 32.

[0054] When the pin enters between the two detection rollers 32, one first cylinder 222 is retracted and the other first cylinder 222 is extended, so that the next pin to be detected is temporarily retained on the conveyor belt 213, and the above steps are repeated until the pin detection work is completed.

[0055] In one embodiment of the present application, Figure 1 As shown, two groups of support frames 31 may also be included.

[0056] The two groups of support frames 31 are respectively arranged on the detection platform 1 , and the two detection rollers 32 are respectively rotatably arranged between the two groups of support frames 31 .

[0057] It should be noted that the support frame 31 and the roller shaft 321 described in this embodiment are rotatably connected via a bearing.

[0058] In one embodiment of the present application, Figure 6 As shown, a discharge chute 71 is provided between a group of support frames 31 .

[0059] It should be noted that the discharge chute 71 described in this embodiment is tilted, and the highest point of one end of the discharge chute 71 is lower than the height of the pin during detection.

[0060] As a possible situation, in order to prevent the pin shaft from being scratched in the discharge chute 71, the discharge chute 71 can be made of polyethylene material.

[0061] In one embodiment of the present application, Figure 6 As shown, a display 81 is provided on the control box 6 .

[0062] Specifically, the data of the pin during the detection process and the monitoring data of the pin and the detection roller 32 by the infrared detection device 5 can be displayed on the display 81. Workers can observe the detection data on the display 81 to determine whether the straightness of the pin meets the technical requirements, whether there are cracks inside the pin, and the working status of the detection roller 32.

[0063] As a possible scenario, the display 81 may be provided with a warning device (not shown in the figure), which can sound an alarm when abnormal data appears, thereby alerting workers so that they can pick out defective products to prevent them from entering the market.

[0064] In one embodiment of the present application, Figure 6 As shown, a plurality of supporting legs 91 are symmetrically provided at the four corners of the lower surface of the testing platform 1 .

[0065] It is understandable that the legs 91 can reduce the contact area between the testing platform 1 and the ground, thereby increasing the pressure between the two and improving the stability of the device during use.

[0066] As a possible situation, in order to facilitate the movement of the device, a universal wheel (not shown in the figure) can be installed at the bottom of the support leg 91. The universal wheel can have a self-locking function, thereby providing stable support during use.

[0067] The crawler pin shaft detection device of the embodiment of the present application sets up a feeding mechanism to push multiple completed pin shafts into the detection mechanism in sequence. The pin shaft with abnormal external shape will apply unbalanced external force to the detection roller after rotation. This external force is sensed by the pressure sensing film, thereby realizing the detection of the straightness of the pin shaft. At the same time, the infrared detection device is used to detect possible cracks on the pin shaft, so that the pin shaft detection result is highly accurate. In addition, the device can detect multiple pin shafts at the same time. After the detection is completed, the pin shaft moves autonomously, making the device suitable for various survey methods such as census and sampling, and the detection efficiency is high.

[0068] In summary, the track pin shaft detection device of the embodiment of the present application is applicable to various survey methods such as census and sampling, and has high detection efficiency and high accuracy of detection results.
