Description

Technical Field

[0001] The invention relates to a device and method for detecting the firing torque and movement stroke of a firing mechanism trigger. Background Art

[0002] Currently, with the evolving international landscape and the rapid development of equipment science and technology, my country's national defense development has also entered a critical phase. The firing performance of equipment grips plays a crucial role. As one of the most critical components of equipment, the firing mechanism is crucial for proper triggering during use. To accurately complete testing, inspections, training, competitions, and safety testing, and ensure reliable wartime equipment performance, the current procedure is to place the assembled firing mechanism in a vise and hook the trigger with a dynamometer to measure trigger torque and travel.

[0003] This inspection operation has the following problems: (1) Low inspection accuracy: The firing mechanism is clamped in a vise and measured with a dynamometer. The force applied during the stretching process cannot be uniform, and the trigger hook needs to be manually held. This can easily lead to inaccurate torque values ​​and movement strokes displayed by the dynamometer when the trigger of the firing mechanism is fired, and cannot meet the technical requirements for the use of weapons and equipment; (2) The firing mechanism is easily damaged: Due to the use of a vise for clamping, if the clamp is too tight, the inner cavity of the firing mechanism may be deformed, resulting in scrap; if the clamp is too loose, the firing mechanism may fall during stretching, causing bumps and damage; and the operator needs to cooperate with at least two people during the inspection, which is extremely inconvenient; (3) The operator has high labor intensity: Due to the use of a vise for clamping, the clamping and tightening need to be repeatedly adjusted to ensure that the firing mechanism is not damaged, which is time-consuming and labor-intensive, and the operator has high labor intensity;

[0004] (4) High risk: Since the stretching needs to be done manually, one person needs to hold the hook during the operation. If the hook comes off, it is easy to cause hand injuries and the firing mechanism to fall and be damaged. (5) Long detection time and low accuracy and efficiency: Two people are required to cooperate in the detection, one person holds the hook by hand and the other stretches the hook for measurement. Due to the manual support, the measurement accuracy is difficult to guarantee and the measurement needs to be repeated many times. This process takes a long time and is inefficient.

[0005] Chinese utility model patent CN220609067U discloses a trigger force feedback mechanism for a game controller, comprising a feedback mechanism housing, a force transmission plate and a trigger button coaxially connected to the feedback mechanism housing, located on the inner and outer sides thereof, respectively. The feedback mechanism housing has a strip-shaped opening located between the force transmission plate and the trigger button. One edge of the force transmission plate extends out of the strip-shaped opening and abuts the trigger button. The other edge of the force transmission plate is connected to a drive mechanism for driving the force transmission plate to reciprocate. A gap is provided between the trigger button and the strip-shaped opening for the force transmission plate to reciprocate. The feedback mechanism housing is provided with a torsion spring for driving the trigger button to reset. The feedback mechanism housing is also provided with a first angle detector and a second angle detector for detecting the angular position of the force transmission plate and the trigger button, respectively. The first angle detector and the second angle detector are both electrically connected to the drive mechanism. The above technical solution only quickly adjusts the force applied by the force transmission plate to the trigger button to simulate the recoil of a gun or the pulling force of an archery shot, but cannot detect the firing torque and travel of the firing mechanism.

[0006] Chinese invention patent CN112361875B discloses an automated auxiliary platform for factory reliability testing of pistols, comprising a first-shot loading module with a counterweight base fixed to the counterweight base, a sliding workbench, a clamping and positioning module, and a residual ammunition detection module. The clamping and positioning module is used to clamp and fix the pistol. The first-shot loading module can move parallel to the axis of the relative barrel and is used to pull the pistol sleeve to perform linear motion along the barrel axis to complete the first-shot loading action. The sliding workbench is provided with a firing module and a magazine release module. The sliding workbench can slide relative to a direction perpendicular to the gun body to compress the pistol and drive the firing module and magazine release module into place. The firing module is used to pull the trigger to complete the shooting action. The magazine release module is used to press the pistol's unloading button to complete the magazine release action. This technical solution uses the relevant components of the auxiliary platform to fix the pistol for pistol reliability testing. However, its complex structure cannot detect the trigger firing torque and movement range of the pistol. Summary of the Invention

[0040] As attached Figure 1-10 As shown, the method for detecting the firing torque and firing stroke of the firing mechanism trigger of the present invention adopts the following steps:

[0041] S1. Adjust the adjustment screws 7 at the four corners of the bottom surface of the base 1 so that the bubble of the spirit level 4 placed on the top surface of the base 1 is centered. Pass the scale marking cylinder 13 of the measuring assembly through the fixing sleeve 12.

[0044] S4. If the trigger firing torque and trigger travel values ​​do not meet the requirements, debugging is required before testing and measurement. (Debugging is performed on the internal components of the firing mechanism 6. The specific debugging process is as follows: remove the firing mechanism 6, remove the firing mechanism side cover screws, press the hammer to remove the trigger, file the trigger at the R10 arc, reassemble the filed trigger, clamp it between the upper clamping assembly 51 and the lower clamping assembly 52 of the firing mechanism, and then test whether the firing torque and trigger travel meet the requirements.)

7. A firing mechanism trigger firing torque and motion stroke detection device according to claim 3, characterized in that: The slide rail (21) and the slide block (22) are matched dovetail slides.

8. A method for detecting the firing torque and movement stroke of a firing mechanism trigger, characterized in that: Use the following steps: S1. Adjust the adjustment screws (7) at the four corners of the bottom surface of the base (1) so that the bubble of the level (4) placed on the top surface of the base (1) is centered; pass the scale marking cylinder (13) of the measuring component through the fixing sleeve (12), and after adjusting the position, use the screws on the top of the fixing sleeve (12) to press the scale marking cylinder (13); S2, the firing mechanism (6) to be tested and measured is clamped between the upper clamping assembly (51) and the lower clamping assembly (52) of the firing mechanism after being dialed and hung up, and the trigger (61) of the firing mechanism (6) corresponds to the through hole (31) and is arranged on the left side of the hook of the trigger pull rod (14); S3, the wrench (26) is rotated forward, and the gear shaft (24) is pulled by the wrench (26), and the gear shaft (24) drives the gear (25) and the toothed plate (23) to make the slide block (22) move linearly to the right along the slide rail (21), so that the hook portion of the trigger pull rod (16) hooks the trigger (61) of the firing mechanism (6) until the trigger (61) is fired. At this time, the torque scale of the torque value scale (181) and the travel scale of the motion travel scale (182) pointed by the pointer (19) are read to check whether the trigger firing torque of 15N to 38N and the trigger motion travel of 12mm to 35mm are met; S4. If the trigger firing torque value and trigger movement stroke value do not meet the requirements, they need to be debugged and then tested and measured; S4, pull the wrench (26) in the opposite direction until the trigger (61) releases the hook of the trigger rod (14), remove the firing mechanism (6), and sequentially perform the detection and measurement of the next firing mechanism (6).
