Description

Technical Field

[0001] The present invention relates to the technical field of equipment performance detection, and in particular to an equipment shell impact resistance detection device and method. Background Art

[0002] Equipment casing impact testing is a test of the external impact resistance of various equipment casings (such as electronic devices, mechanical instruments, and vehicle casings). It aims to evaluate the casing's performance against dynamic loads such as impact, drops, and crushing, ensuring it effectively protects internal components and extends the life of the equipment. Equipment casing impact testing equipment is a specialized testing device used to assess the casing's ability to withstand external impact. Its core function is to quantitatively test the structural strength, deformation resistance, and protective performance of the device casing by simulating real-world impact scenarios. This ensures that the device can effectively withstand external impacts and safeguard internal components during transportation and use. Common testing methods include pendulum impact testing, drop hammer impact testing, and pneumatic impact testing. Pneumatic impact testing involves adjusting the air pressure to control the impact head's speed and force to perform impact testing on the casing specimen. In modern industrial production, the impact resistance of equipment casings is directly related to the safety of internal components and the lifespan of the equipment, making it a key indicator of product quality assessment. At present, traditional equipment casing impact resistance testing mostly adopts a single fixed-position impact test method, which is difficult to fully simulate the multi-directional impact conditions that the equipment may encounter in actual use, resulting in one-sided test results and an inability to truly reflect the overall impact resistance of the casing. Some existing testing equipment uses a simple clamping method. Under the action of high impact force, the workpiece is prone to loosening and displacement, which not only affects the accuracy of the test data but also may cause safety hazards. In addition, the impact head position adjustment accuracy of traditional equipment is low, making it difficult to accurately test key parts of the casing (such as corners and weak areas), and lacks an effective buffering mechanism. The rebound after the impact can easily cause a secondary impact, interfering with the reliability of the test results. Summary of the Invention

[0013] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0014] Example: Figure 1-8 As shown, the present invention provides a device and method for testing the impact resistance of equipment casings. The support frame 11 is placed stably on the laboratory floor. The anti-slip feet 45 on its bottom are made of rubber with anti-slip grooves and securely connected to the support frame 11 via screws, ensuring the device is stable and stable during testing. High-strength bolts secure the base plate 20 to the upper surface of the support frame 11, ensuring a tight fit and providing a stable foundation for subsequent component installation. When the support frame 11 is placed firmly on the laboratory floor, the design details of the anti-slip feet 45 further demonstrate their scientific merit. The rubber material not only provides excellent anti-slip properties but also absorbs minor vibrations from the floor, reducing the impact of external vibrations on test results. The anti-slip grooves feature a unique cross-wave design, increasing friction with the floor. In actual testing, the friction coefficient on wet floors can reach over 0.8, ensuring the device remains motionless even during high-intensity testing. High-strength stainless steel hexagon socket head screws are used for the screw connections, tightened to a standard torque of 8 N·m using a torque wrench to ensure a secure connection.

[0015] Two slide rails 26 are symmetrically mounted on the upper surface of the base plate 20. The slide rails 26 are linear guide rails, and their installation accuracy is calibrated using a spirit level to ensure that the two slide rails 26 are at the same horizontal height and parallel to each other. Limit pins 44 are symmetrically fixedly mounted on one side of the upper surface of the base plate 20 near the slide rails 26. The two limit pins 44 serve to limit the unilateral linear motion stroke of the slider 25, preventing the slider 25 from exceeding the range of movement. The first motor 22 is fixed to one side of the support frame 11, and the motor output shaft is rigidly connected to the first screw rod 21 through a coupling. The connection between the first motor 22 and the first screw rod 21 adopts a plum blossom coupling, which has excellent shock absorption performance and angle compensation capabilities. It can effectively absorb vibrations during motor operation, ensuring that the coaxiality error of the first screw rod 21 during rotation does not exceed 0.01mm, and the movement accuracy of the first nut seat 23 reaches ±0.02mm. The first screw rod 21 is rotatably connected to the upper surface of the base plate 20 to ensure smooth rotation. The first nut seat 23 is threadedly mounted on the first screw rod 21, and its lower surface is fixedly connected to the slider 25. The slider 25 slides with the slide rail 26. The first nut seat 23 is precisely threaded with the first screw rod 21. The slider 25 fixedly connected on its lower surface and the slide rail 26 form a high-rigidity linear motion pair. When the first motor 22 drives the first screw rod 21 to rotate, the first nut seat 23 can drive the movable support plate 24 to achieve millimeter-level high-precision horizontal movement along the slide rail 26. On the upper surface of the movable support plate 24, a second motor 28 is fixedly mounted on one side. The output shaft of the second motor 28 is connected to the second screw rod 27, and the second screw rod 27 is rotatably connected to the upper surface of the movable support plate 24. The second nut seat 29 is threadedly mounted on the second screw rod 27, and its upper end is fixedly connected to the support platform 13. The movable guide rods 30 symmetrically installed on the upper surface of the movable support plate 24 are respectively slidably connected to the guide sleeves on both sides of the lower surface of the support platform 13, playing a guiding role, ensuring that the support platform 13 is smoothly adjusted to the other direction of the support platform 13 under the drive of the second screw rod 27. According to the detection standard and the shell test requirements, the first motor 22 is started, the first motor 22 drives the first screw rod 21 to rotate, and the first nut seat 23 drives the movable support plate 24 to move horizontally along the slide rail 26, thereby adjusting the horizontal position of the support platform 13. At the same time, the second motor 28 is started, the second motor 28 drives the second screw rod 27 to rotate, and the second nut seat 29 drives the support platform 13 to move, which can change the horizontal position of the support platform 13 in the other direction, so that the shell body 33 is in a suitable test position to meet the impact detection requirements of different positions. A clamping assembly 31 is symmetrically mounted on the upper surface of the support platform 13. This assembly comprises a base 34, the upper end of which is pivotally connected to a first connecting rod 35 and a second connecting rod 36 via respective pins. One end of the first connecting rod 35 and one end of the second connecting rod 36 are pivotally connected to a handle 37 via a pin, forming a toggle mechanism. A set plate 38 is fixedly mounted on the lower surface of one side of the second connecting rod 36, and a clamping pin 39 is symmetrically fixed to the outer surface of the set plate 38.At the same time, according to the design layout, a plurality of positioning pins 32 distributed in a rectangular array are fixedly installed on the upper surface of the support platform 13. The upper ends of these positioning pins 32 can be inserted into the positioning holes of the shell body 33 to achieve the initial positioning of the shell, and the shell body 33 is located between the two clamping components 31 to facilitate subsequent clamping and fixing. In the operation link of fixing the shell body 33, the matching tolerance of the positioning pins 32 and the shell positioning holes is precisely calculated. The positioning pins 32 adopt a clearance fit of H7 / g6, which can not only ensure the rapid installation of the shell, but also provide sufficient positioning accuracy, so that the positioning error of the shell in the horizontal direction does not exceed 0.1mm. When the first connecting rod 35 and the second connecting rod 36 enter the "dead point" position, it can be seen from mechanical calculations that the self-locking force of the mechanism can reach more than 500N at this time, which is sufficient to cope with various external forces during the impact test. The head of the clamping pin 39 adopts an arc transition design and is covered with a layer of polyurethane rubber with a thickness of 0.5mm. This ensures the clamping force on the shell while avoiding leaving indentations on the shell surface. The shell body 33 to be tested is carefully placed on the support platform 13, so that the positioning hole at the bottom of the shell body 33 accurately fits the positioning pin 32 on the support platform 13, completing the initial positioning of the shell and preventing the shell from deviating significantly during subsequent operations. Next, the operator grasps the handle 37 and rotates it clockwise. The handle 37 drives the first connecting rod 35 and the second connecting rod 36 to move in conjunction. When the first connecting rod 35 and the second connecting rod 36 rotate to a specific angle and enter the "dead point" position, the elbow clamp principle is used. At this time, even if external force is applied, the handle 37 will not rotate in the opposite direction, achieving self-locking. In this state, the triangle plate 38 produces a downward pressure action, driving the clamping pin 39 to press tightly against the upper surface of the shell body 33, firmly fixing the shell to the support platform 13. Backplate 14 is fixedly mounted on one side of support frame 11. The upper portion of backplate 14 and the upper surface of support platform 13 are bolted together to connect two mirror-image impact guide rods 16. Springs 19 are sleeved around the lower ends of both impact guide rods 16, acting as buffers. A cylinder 15 is fixedly mounted on the upper surface of backplate 14. The output end of cylinder 15 is fixedly connected to T-plate 17 via a connector. The outer surface of T-plate 17 slides over the two impact guide rods 16, ensuring stable sliding of T-plate 17 on them. After completing all the aforementioned preparations, cylinder 15 is activated. The piston rod of cylinder 15 extends and retracts at a set speed and stroke, driving T-plate 17 to slide rapidly along impact guide rods 16, accelerating the impact head 18 downward and striking the surface of housing body 33 with a predetermined impact force. At the moment of impact, the spring 19 at the bottom of the impact guide rod 16 is rapidly compressed to absorb the rebound energy of the impact head 18, preventing the impact head 18 from hitting the shell again after rebounding and interfering with the test results. The spring 19 can absorb most of the rebound energy in a very short time, preventing the impact head 18 from hitting the shell again after rebounding, thereby effectively preventing the secondary impact from interfering with the test results. During the impact test, the control of the cylinder 15 adopts a closed-loop control system.The pressure value inside the cylinder is fed back in real time through a pressure sensor and compared with the preset pressure curve. If a deviation occurs, the control system immediately adjusts the cylinder's air intake flow and pressure to keep the error in the impact velocity within ±2%. The spring 19 is made of chrome-vanadium steel with a high elastic modulus and good fatigue performance. It has no obvious attenuation after 100,000 fatigue tests. When absorbing impact energy, it can reduce the rebound speed of the impact head 18 to less than 10% of the initial speed within 5ms. Inside the T-plate 17, a third screw rod 40 is connected to the bearing through rotation. One end of the third screw rod 40 is fixedly connected to the adjustment handwheel 43 to facilitate manual adjustment by the operator. The outer surface of the third screw rod 40 is threadedly connected to a connecting block 42. A symmetrical groove 41 is formed on one side of the T-plate 17. The outer surface of the connecting block 42 is slidably connected to the groove 41, allowing the connecting block 42 to move horizontally on the T-plate 17. The lower surface of the connecting block 42 is fixedly connected to the impact head 18, thereby adjusting the position of the impact head 18. The operator rotates the adjustment handwheel 43, which drives the third screw rod 40 to rotate. When the third screw rod 40 rotates, the connecting block 42, which is threadedly connected to it, slides along the groove 41 on the T-plate 17, thereby precisely adjusting the position of the impact head 18. This adjustment method allows the impact head 18 to move horizontally, further improving the impact accuracy and ensuring that the impact head 18 is accurately aligned with the test point on the housing body 33, meeting the precise positioning requirements of different test points. When adjusting the position of the impact head 18, the third screw rod 40 uses a TBI brand high-precision ball screw with a lead of 5mm, which can achieve a fine adjustment accuracy of ±0.01mm in the horizontal direction of the impact head 18. Throughout the entire testing process, the control system utilizes Advantech's industrial-grade control unit, equipped with specialized testing software developed in LabVIEW. This system not only collects and processes data in real time but also features a data anomaly alarm function. If the impact force data exhibits unusual fluctuations, the system immediately issues an audible and visual alarm and automatically stops the test, ensuring the safety of the testing process and the reliability of the data. After completing an impact test, the device's control system restarts the first and second motors 22 and 28 according to the pre-set test program, precisely adjusting the horizontal position of the support platform 13 according to the new parameters. Simultaneously, the operator rotates the adjustment handwheel 43 as needed to adjust the position of the impact head 18, precisely moving it to the next test point on the housing 33. During testing, the device's built-in Kistler 9327B piezoelectric force sensor (range 0-8000N, accuracy 0.3%FS) collects impact force data in real time at a sampling frequency of 20kHz.After completing an impact, the control system automatically drives the first motor 22 and the second motor 28 to adjust the position of the support platform 13 according to the preset program, and fine-tunes the impact head 18 by adjusting the handwheel 43, and performs cyclic testing on more than a dozen key areas such as the corners and weak parts of the equipment casing. Each test point is repeatedly impacted 5 times, and finally a detailed test report containing data such as the impact force-time curve and the strain distribution cloud map is generated, thereby completing the impact test process.

[0016] Working principle: When the device is working, the shell body 33 is first placed on the support platform 13, and the positioning pin 32 is inserted into the corresponding positioning hole of the shell to achieve preliminary positioning to prevent the shell from deviating in a large range during subsequent operations. Next, the operator rotates the handle 37, which drives the first connecting rod 35 and the second connecting rod 36 to work in a coordinated manner, using the principle of leverage to change the direction and magnitude of the force. When the handle 37 is turned to a specific angle, the first connecting rod 35 drives the second connecting rod 36 to enter the "dead point", realizing the toggle clamp principle. Pulling the handle 37 in the opposite direction releases the self-locking and loosens the workpiece, and the triangular plate 38 produces a downward pressing action, which in turn drives the pressing pin 39 to press tightly against the surface of the shell body 33, firmly fixing the shell on the support platform 13 to ensure that the shell will not shift during the impact test; Subsequently, the first motor 22 is started to drive the first screw rod 21 to rotate. During the rotation of the first screw rod 21, the first nut seat 23 threaded with it will drive the movable support plate 24 to move horizontally along the slide rail 26, thereby adjusting the horizontal position of the movable support plate 24; At the same time, the second motor 28 is also started to drive the second screw rod 27 to rotate. The second nut seat 29 moves with the rotation of the second screw rod 27, changing the horizontal position of the support platform 13 in another direction, so that the support platform 13 can adapt to the impact test requirements of different directions and positions; The operator then turns the adjustment wheel 43, which drives the third screw 40. As the third screw 40 rotates, the connecting block 42, threadedly connected to it, slides along the groove 41 on the T-plate 17, precisely controlling the impact position of the impact head 18 to meet the precise positioning requirements of different test points. Once ready, the cylinder 15 begins operating, its piston rod extending and retracting, driving the T-plate 17 to slide rapidly along the impact guide rod 16, accelerating the impact head 18 downward and striking the surface of the housing body 33. The spring 19 at the bottom of the impact guide rod 16 absorbs the rebound energy of the impact head 18 after impact, preventing it from bouncing back and striking the housing again, which could distort the test results. After completing an impact test, the first and second motors 22 and 28 are restarted to adjust the horizontal position of the support platform 13 and, if necessary, rotate the adjustment wheel 43 to change the impact position of the impact head 18. Repeating the above impact test process allows impact testing of different parts of the device housing, providing comprehensive data on the housing's impact resistance.
