Description

Technical Field

Background Art

[0002] The performance of the 410-caliber hunting rifle's repeating mechanism, a common civilian and hunting firearm, directly impacts its reliability, safety, and accuracy. During continuous firing, the repeating mechanism is subjected to frequent and complex impact forces, including recoil, the reaction force from ejected cartridge cases, and the collision forces between mechanism components. Therefore, impact testing of the 410-caliber hunting rifle's repeating mechanism is a critical step in ensuring its quality and performance.

[0003] Currently, existing firearm impact testing devices have many shortcomings. On the one hand, most testing devices are highly versatile, but lack designs tailored to the characteristics of the 410-caliber shotgun's continuous firing mechanism.

Existing testing devices are difficult to accurately simulate the impact conditions during actual operation. On the other hand, existing testing devices need to be improved in terms of test accuracy and degree of automation: they cannot accurately control the frequency, force, and direction of the impact.

[0046] In the embodiment of the present disclosure, as shown in the attached Figure 3 As shown, the rear end face of the impact hammer 4 is fixedly connected with a touch pressure sensing coil 401. When the touch pressure sensing coil 401 contacts the fixing seat 31, the circuit is connected. When the impact hammer 4 is installed on the supporting plate 6101, the front end face of the impact hammer 4 is flush with the front end face of the vertical plate of the clamping plate 63. After the impact hammer 4 is installed, it is flush with the front end face of the vertical plate of the clamping plate 63 to ensure that the impact force of the impact simulation is balanced and easy to disperse.

[0048] In the embodiment of the present disclosure, as shown in the attached Figure 4 , Attachment Figure 5 and attached Figure 8As shown, a clamping shaft is welded to the bottom of the connecting clamping ring 61, and a protrusion is welded to the periphery of the bottom of the clamping shaft. The protrusion is clamped in a rectangular groove opened on the inner wall of the transmission gear ring 62.

After loosening the clamping plate 63, the spring pushes the reset push plate 6302 to move inward, and the moving rod 6301 is pulled inward at the same time, causing the clamping plate 63 to move toward the middle, clamping and fixing the impact hammer 4. At the same time, the elastic potential energy of the spring is used to maintain the inward movement trend of the reset push plate 6302, thereby ensuring the clamping effect of the clamping plate 63 on the impact hammer 4.

[0049] In the embodiment of the present disclosure, as shown in the attached Figure 9-10 As shown, the clamping drive mechanism 8 includes a clamping drive shaft 81, a transmission chain 82 and a clamping block 83. The surface of the clamping drive shaft 81 is engraved with a bidirectional thread. The two ends of the clamping drive shaft 81 are threadedly connected to the clamping block 83. The front end of the right clamping drive shaft 81 is coaxially connected to the drive shaft of the servo motor. The front sides of the two clamping drive shafts 81 are respectively fixedly welded with two baffles 8101. The transmission chain 82 is installed between the baffles 8101, and a gear is fixedly connected on the clamping drive shaft 81 between the two baffles 8101.

The left clamping drive shaft 81 is rotated by the transmission chain 82 driving the gear to rotate. The two clamping drive shafts 81 are rotated synchronously through the transmission chain 82, and the two-way thread is used to drive the clamping blocks 83 on the front and rear sides to move toward each other, so as to clamp and fix the 410-caliber shotgun burst mechanism to be tested.

[0050] In the embodiment of the present disclosure, as shown in the attached Figure 3 As shown, the bottom plate of the fixing seat 31 is fixedly connected to the top surface of the firing mechanism fixing module 2 by a bolt assembly, the front end surface of the vertical plate of the fixing seat 31 is fastened to the electromagnetic driver 32 by a thread, and two buffer rings 3101 with different circle diameters are fixedly connected in the annular groove of the front end surface of the vertical plate of the fixing seat 31. The buffer ring 3101 can provide secondary buffering protection for the impact hammer 4 when it is reset. At the same time, the two-stage buffering can be achieved by utilizing the different circle diameters to improve the buffering protection effect. The impact force of the impact simulation is regulated by the different number of coils connected to the electromagnetic driver 32 through circuit control design, and the impact drive of the impact hammer 4 is realized through the electromagnetic driver 32. At the same time, the friction force can be minimized to the maximum extent and space can be provided for the adjustment of the direction.

[0051] The working principle of this embodiment is as follows:

[0052] During the test preparation phase, the 410-caliber shotgun rapid-fire mechanism is placed between the top surface of the rapid-fire mechanism fixing module 2 and the clamping block 83. After the external control end activates the hydraulic drive rod to push the connecting block 201 to move, the clamping drive shaft 81 drives the two clamping blocks 83 to move, thereby achieving fixed clamping of the 410-caliber shotgun rapid-fire mechanism in the left and right directions. At the same time, the displacement sensor and angle sensor in the connecting block 201 monitor the installation position and posture of the rapid-fire mechanism in real time. If there is any installation deviation, the hydraulic drive rod is automatically adjusted through the external control end until the rapid-fire mechanism is in the accurate test position.

[0053] According to the test requirements, the test parameters of the impact simulation are set, including impact strength, impact frequency and impact direction, etc. The industrial control computer sends the set parameters to the external control end. The control end starts the monorail cylinder 7301 through the external control end according to the control command received, and pushes the moving card 73 to move. The moving card 73 moves forward until the bevel gear at the front end of the sleeve 72 is engaged with the small bevel gear at the right end of the rotating shaft on the rotating plate 501. After the drive motor is started through the external control end, the rotating plate 501 is driven to rotate, and the rear locking block 73021 is clamped to the transmission gear installed on the top surface of the rotating plate 501, the transmission gear is locked, and the moving card 73 moves back straight When the bevel gear at the rear end of the sleeve 72 meshes with the transmission gear on the top surface of the rotating plate 501, the drive motor is started through the external control end to drive the transmission gear to rotate, and the transmission gear ring 62 is used to adjust the angle of the supporting plate 6101, and the front locking block 73021 is clamped to the small bevel gear at the right end of the rotating shaft of the rotating plate 501 to lock the rotating shaft, thereby realizing unidirectional adjustment. The control end is also used to control the number of coils connected to the electromagnetic driver 32, so that the impact hammer 4 generates an impact force of corresponding magnitude. Finally, the electric drive slider 5 is used to adjust the distance between the impact hammer 4 and the fixing seat 31, so that the impact hammer 4 accurately impacts the designated part of the burst mechanism.

[0054] During the impact test, acceleration sensors, strain gauge sensors, displacement sensors, and pressure sensors installed at key locations on the continuous firing mechanism collect various performance data of the continuous firing mechanism in real time and transmit the data to the data acquisition system. The data acquisition system converts the collected analog signals into digital signals and transmits them to the industrial control computer via data cables for storage and processing.

[0055] After completing the preset number of tests or test time, the external control end controls the impact simulation module 3 to stop working, the impact hammer 4 stops impacting, the hydraulic drive rod is turned off to release the clamping block 83, and the tested continuous firing mechanism is removed from the continuous firing mechanism fixing module 2 to complete an impact test process.
