Abstract
Description
Technical Field
[0001] This invention belongs to the field of artillery systems, specifically relating to a device and method for precise measurement of torque in artillery systems. Background Technology
[0002] In the performance inspection of armored vehicle artillery systems, the current testing methods for torque-related aspects, such as the unbalanced torque of the gun, the frictional torque of the gun's lifting and lowering parts, the maximum stabilizing torque, and the frictional torque of the turret, involve using a spring scale to measure the tension, using millimeter coordinate paper to read the distance the gun moves on the millimeter coordinate paper, and then calculating the torque value according to the formula.
[0003] When using a spring scale to measure and calculate the torque of an artillery system, the spring scale itself introduces errors in measuring the tension. This is because the operator's reading of the scale's display is an estimate, and the distance measurement on millimeter coordinate paper involves multiple measurements and averaging. Therefore, the calculated torque value is, strictly speaking, an approximation, not a precise figure. Furthermore, the measured torque values cannot be stored in real time, leading to significant difficulties in data recording and subsequent management, poor traceability, and requiring repeated measurements during assembly and debugging, quality department inspections, and user representative acceptance. This hinders production efficiency and increases production costs. Summary of the Invention

[0019] The purpose of this invention is to provide a precise torque measurement device and method for artillery systems. By designing and manufacturing a precise torque measurement device for artillery systems, the torque value of artillery systems can be measured and calculated accurately, reliably, and conveniently, greatly saving the time of final assembly and commissioning.

[0020] Based on the torque detection requirements of artillery systems, this technical solution is formulated to design a precise torque measurement device for artillery systems. This device adopts multi-channel fully digital electronic servo control technology, with electric actuators automatically applying tension and laser sensors testing dynamic displacement. It enables the artillery to move smoothly in four directions (up, down, left, and right) and collects force and displacement data during transient movements. Through calculation, it achieves precise measurement of the torque of the artillery system. Detailed implementation method:
[0022] The present invention patent is described in further detail below.
[0023] Figure 1 The schematic diagram of the torque measurement device for the artillery system mainly includes: 1 set of movable main frame (1), 4 sets of electric servo actuators (2), 4 sets of load sensors (3), 4 sets of electromagnetic automatic release devices (4), 2 sets of laser dynamic displacement sensors (5), and 1 set of control system (6).
[0024] The electric servo actuator (2) includes 4 sets. Each set of electric servo actuator (2) includes: a fixed end and a lead screw. The fixed end is fixed to the movable host frame (1) by a thread. The fixed end is connected to the lead screw. The lead screw is used to generate a certain tension and pull a certain displacement.
[0025] The lead screw is connected to a load sensor (3), which is used to measure the force applied to the connector.
[0026] The load sensor (3) is connected to the connection point of the connector through the electromagnetic automatic release device (4). When energized, it is connected to the connector by the electrically controlled magnetic force. When de-energized, it loses the magnetic force and disconnects from the connector.
[0027] Laser-type dynamic displacement sensors (5) are provided on the left and upper sides of the connector, respectively, for measuring horizontal and vertical displacement.
[0028] The connector includes a ring and four connection points. The four connection points are located at the center of the ring, at the top, bottom, left, and right sides, and are used to connect the electromagnetic automatic release device (4). The center of the ring is used to place the cannon barrel (7).
[0029] Furthermore, for different artillery barrels (7), only the matching connectors need to be replaced.
[0030] The control system (6) connects to and controls the electric servo actuator (2), the load sensor (3), the electromagnetic automatic release device (4), and the laser dynamic displacement sensor (5).
[0031] Figure 2This is a schematic diagram of the use of the precise torque measuring device for artillery systems. When measuring the torque of an artillery system, move the precise torque measuring device to a convenient position and fix it. Connect the artillery barrel (7) to the device. After all preparations are complete, start the control system (6) to begin the measurement. The electric servo actuator (2) is used to apply tension to the artillery barrel in four directions: up, down, left, and right. The laser dynamic displacement sensor (5) measures the dynamic change process of the barrel position. The electromagnetic automatic release device (4) uses an electromagnetic unhooking method to quickly remove the force applied to the barrel. All of the above are controlled by the control system (6). The torque measurement of the artillery system can be performed manually by operating the control system software according to the measurement requirements. The system automatically completes the work of motion control, data acquisition, test management and data processing of the overall test system, and displays and stores data in real time. This enables precise measurement of the torque of the artillery system, improves production efficiency, and enhances the level of quality management.
[0032] 1. Control by applying a fixed force value continuously for a certain period of time and by applying a transient force value.
[0033] The control system (5) gives the lead screw a tension command, and the lead screw pulls the connector according to the command. The tension is measured by the load sensor (3). When the preset tension is reached, for example, 100N, the control system (6) controls the lead screw to move at a constant speed for a certain period of time. At this time, the tension remains unchanged. The displacement of the connector is measured by the laser dynamic displacement sensor (5) to obtain the locking drift speed C.
[0034] C = 0.96A / (L*t)
[0035] A represents the distance (mm) the artillery moves within time t;
[0036] t is the time (s) during which the force is applied.
[0037] L is the distance from the muzzle face to the center line of the trunnion.
[0038] Transient force value control process:
[0039] The control system (6) gives the upper and lower lead screws a tension command. The lead screws gradually increase the force according to the command to pull the connecting parts until the connecting parts start to move. At this time, the tension is measured by the load sensor (3). The control system (6) controls the lead screw to move smoothly for a certain distance. The displacement of the connecting parts is measured by the laser dynamic displacement sensor (5). After reaching the preset distance, the tension is recorded by the load sensor (3) to obtain the unbalanced torque of the cannon.
[0040] M = (P1 - P2) / 2 * L
[0041] P1 is the pulling force when the cannon moves upward;
[0042] P2 is the pulling force when the cannon moves downwards;
[0043] L is the distance from the muzzle face to the center line of the trunnion.
[0044] The device of the present invention can also be used to measure other operating conditions and parameters, which will not be described in detail here.
[0045] 2. Control system (6) collects the dynamic position change process of the artillery under the action of tension in the four directions of up, down, left and right.
[0046] 3. The control software integrates functions such as motion control, data acquisition, test management and data processing of the overall test system.
[0047] This invention enables precise measurement of torque in artillery systems, improving testing accuracy and efficiency, and further enhancing the reliability and quality of artillery performance. Simultaneously, the measured torque results are stored in real-time and traceable, facilitating subsequent data management and improving quality management.
[0048] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
