Abstract
Description
Technical Field
[0001] This utility model relates to the field of lock anti-drilling testing technology, specifically to a lock anti-drilling testing device with a sliding platform. Background Technology
[0002] Existing lock drill-proof testing machines are designed to simulate standardized attack scenarios, but they suffer from significant shortcomings in terms of testing accuracy, objectivity of result determination, and effective data utilization. Specifically, these shortcomings are mainly reflected in the following aspects:
[0003] (1) Lack of core monitoring indicators: Existing equipment can only control and record the working time of the electric drill, and is completely unable to monitor and quantify the most critical physical indicator of the lock's anti-drilling performance in real time—the drilling depth. This makes the test process deviate from the true nature of physical damage, and the control method is crude.
[0004] (2) Result judgment relies on subjectivity: Due to the lack of objective data such as drilling depth, it is necessary to judge whether the lock has failed by manual visual inspection after the test. This judgment method is highly subjective, inconsistent, and inefficient, and it is difficult to give an accurate conclusion on the critical failure state, which affects the fairness and reproducibility of the test results.
[0005] (3) Limited value of test data: Existing technologies can only provide a qualitative result of "pass / fail" and a fixed test duration, losing dynamic performance data throughout the drilling process. This makes it impossible to conduct detailed analysis of the test (such as calculating the precise failure time, analyzing changes in drilling rate, etc.), resulting in low data value and difficulty in effectively supporting the performance comparison, optimization and development, and quality improvement of lock products.

[0022] Figure 2 This is a schematic diagram of the electric drill feed device in an embodiment of the present invention. Detailed Implementation
[0023] The present invention will be further described below with reference to the accompanying drawings. It should be noted that this embodiment is based on the present technical solution and provides detailed implementation methods and specific operation processes, but the protection scope of the present invention is not limited to this embodiment.
[0024] This embodiment provides a lock anti-drilling testing device with a sliding platform, such as... Figure 1-2 As shown, it includes a main frame 100 and a control system, a drilling depth measurement system 2, an electric drill feed device 3, a human-machine interface 4, a camera device 5, an electric drill 6, a drill bit 7, a lock core clamp 9, a lock core clamp adjustment device 10, and a loading load 11.
[0025] The lock cylinder clamp 9 is located in front of the electric drill feed device 3 and is used to clamp and fix the lock cylinder 8 to be tested; the lock cylinder clamp adjustment device 10 is connected to the lock cylinder clamp 9 and is used to adjust the height of the lock cylinder clamp 9; the electric drill feed device 3 is used to fix the electric drill 6 and drive it to move forward; the loading load 11 is connected to the electric drill feed device 3 and is used to provide power for the electric drill 6 to move forward; the electric drill 6 is used to fix the drill bit 7 and drive it to rotate; the drilling depth measurement system 2 is used to measure the displacement of the drill bit 7; the drilling depth measurement system 2, the human-machine interface 4, and the electric drill 6 are all communicatively connected to the control system.
[0026] In this embodiment, the lock cylinder clamp adjustment device 10 includes bases on both sides and set screws. The lower end of the lock cylinder clamp is movably disposed between the bases on both sides. The set screws on both sides extend from the outside of the corresponding base into the inside of the base and tighten the lock cylinder clamp. When it is necessary to adjust the height of the lock cylinder clamp 9, first loosen the set screws, then adjust the height of the lock cylinder clamp so that the position of the drill hole of the lock cylinder coincides with the center of the drill bit, and then tighten the lock cylinder clamp between the bases on both sides again with the set screws.
[0027] Specifically, in this embodiment, the lock cylinder clamp 9 is provided with a template hole for installing the lock cylinder. After the lock cylinder is placed into the template hole, the lock cylinder can be firmly locked with a set screw.
[0028] In this embodiment, the drilling depth measurement system 2 includes a wire encoder; the electric drill feed device 3 includes a sliding platform 31, a sliding guide rail 32, a slider 33, a front wire 35, a rear load connector 36, a front load connector 37, a rear pulley support 38, a front pulley support 39, an electric drill clamping mechanism 310, and a base 311. The sliding guide rail 32 is fixed to the top of the base 311 and extends along the direction of electric drill feed, and the slider 33 is mounted on the sliding guide rail 32; the sliding platform 31 is fixed to the top of the slider 33, and the electric drill clamping mechanism 310 is provided on the sliding platform 31 for mounting the electric drill 6; the front end of the sliding platform 31 is connected to the load 11 via the front wire 35; the wire encoder is connected to the rear end of the sliding platform 31.
[0029] As the load 11 drives the sliding platform 31 to slide forward, the electric drill 6 on the sliding platform 31 drives the drill bit 7 to drill into the lock core, which drives the wire encoder to generate pulse increment changes, thereby accurately measuring the drilling depth.
[0030] In this embodiment, the load 11 includes a counterweight tray, which is movably disposed at the front end of the main frame 100 and used to place counterweights; the counterweight tray is connected to the sliding platform 31.
[0031] More specifically, in this embodiment, two sets of counterweight trays are provided, each connected to both sides of the front end of the sliding platform 31 by steel wire, and each set is used to hold one set of counterweights. The counterweights are made of 45# steel. In this embodiment, the mass of a single set of counterweights is 10kg, and the total mass of the two sets of counterweights is 20kg. After placing the same mass of counterweights on the two sets of counterweight trays, the two sets of counterweights pull the sliding platform 31 through the steel wire rope, providing power to the sliding platform 31, which drives the electric drill 6 to apply a force of 20kg to the lock cylinder 8. The electric drill drives the 6mm drill bit 7 to drill and cut the lock cylinder 8. Different masses of counterweights can be selected according to actual needs.
[0032] Furthermore, in this embodiment, the rear end of the sliding platform 31 is connected to a rear end steel wire 34. One end of the rear end steel wire 34 is connected to the rear end of the sliding platform 31, and the other end is connected to the frame counterweight provided in the main frame 100. The total mass of the frame counterweight is equal to the total mass of the counterweight tray.
[0033] The sliding platform remains stationary when not in use due to the mutual balance between the counterweight and the counterweight tray. When a counterweight is placed on the counterweight tray, the sliding platform can be moved forward.
[0034] In this embodiment, a camera device 5 is also included. The camera device 5 is connected to a support 13 via an adjustment mechanism, and the support 13 is fixed to the main frame 100 via an upright bracket 12. The camera device 5 is positioned to shoot towards the electric drill 6, the drill bit 7, and the lock cylinder 8. The adjustment mechanism includes a telescopic rod 14 and a universal rotating base 15. The telescopic end of the telescopic rod 14 is connected to the universal rotating base 15, and the camera device 5 is rotatably connected to the universal rotating base 15. Through the telescopic rod 14 and the rotating base 15, the camera device 5 can be adjusted for distance, rotation, and pitch, thereby achieving an optimal shooting position. The camera device 5 primarily captures videos and images of the electric drill and drill bit drilling and cutting the lock cylinder.
[0035] Specifically, in this embodiment, the camera device 5 is a bullet camera with 8 megapixels and is a zoom camera.
[0036] In this embodiment, the drilling depth measurement system 2, the electric drill feed device 3, the electric drill 6, the drill bit 7, the lock core clamp 9, and the lock core clamp adjustment device 10 are all installed on the top surface of the main frame 100, the human-machine interface 4 and the camera device 5 are installed on the upright support 12, and the control system is located inside the main frame 100.
[0037] More specifically, both the main frame 100 and the upright support 12 are made of metal and treated with powder coating and painting, resulting in a stable and reliable structure. The top surface of the main frame 100 is machined from No. 45 steel.
[0038] In this embodiment, the control system employs a programmable logic controller (PLC), which has two high-speed pulse outputs, two high-speed pulse inputs, and a certain number of I / O interfaces. The drilling depth measurement system 2 is connected to the control system via the high-speed pulse inputs, which are used to acquire single-phase and AB-phase pulse signals to provide feedback on position and speed information. The electric drill 6 is connected to the control system via the I / O interfaces, which are used to output digital control signals. The PLC is an industrial-grade design, stable and reliable, with strong anti-interference capabilities.
[0039] In this embodiment, the camera device 5 is connected to the server via a switch and sends the captured videos / pictures to the server.
[0040] In this embodiment, the human-machine interface 4 uses a 7-inch color LCD display and a touch screen. It exchanges data with the control system via an RS232 serial port, using the industry-standard Modbus ASCII communication protocol. The computer system exchanges data with the control system via Ethernet interface 1.
[0041] In this embodiment, the electric drill is driven by a contactless AC solid-state relay. The advantage of contactless driving is that it does not generate electrical sparks and does not interfere with other systems.
[0042] In this embodiment, the wire encoder has a resolution of 2500 P / R, which can be increased to 10000 P / R after being quadrupled by the high-speed pulse input of the control system. When the wire is pulled out to a length of 100mm, the encoder rotates once, and the actual displacement resolution is 0.01mm with an accuracy of ±0.1mm. This displacement resolution and accuracy well meet the technical requirements for drilling depth measurement.
[0043] In this embodiment, the programmable controller converts Modbus RTU protocol data into Modbus TCP protocol data through a serial port server to achieve Ethernet data exchange. The serial port server supports multiple network protocols, such as TCP, UDP, ARP, ICMP, HTTP, DNS, DHCP, SNMP, Telnet, and SSH; it has comprehensive management functions, supporting access control, rapid configuration, and online upgrades; each serial port supports four TCP or UDP session connections, and supports multiple working modes such as Modbus TCP, TCPServer, TCP Server, TCP Client, UDPServer, and UDP Client; it also supports WEB access.
[0044] The anti-drilling time and anti-drilling displacement depth values are preset in the control system. After the test starts, the control system obtains the drilling depth of the drill bit from the displacement sensor in real time and determines whether the preset anti-drilling displacement depth value has been reached. When the drilling depth of the drill bit reaches the anti-drilling displacement depth value or the preset anti-drilling time is reached, the test stops.
[0045] The human-machine interface allows users to control the start or stop of the test, set relevant test parameters (locking level, set anti-drilling time, set drilling depth, etc.), display the final test results (actual anti-drilling time and drilling depth, etc.), and some real-time data during the test, such as the current anti-drilling time and anti-drilling displacement. Users can also query historical test data.
[0046] For those skilled in the art, various corresponding changes and modifications can be made based on the above technical solutions and concepts, and all such changes and modifications should be included within the protection scope of the claims of this utility model.
