Description

Technical Field

[0001] This invention relates to the field of firearms testing technology, and in particular to a pistol reliability shooting test bench. Background Technology

[0002] The development of firearms is inseparable from testing, and testing is inseparable from testing equipment. Good testing equipment can reflect the real phenomena of firearms during the firing process, thereby promoting the development of firearms.

[0003] Currently, in pistol testing, the gun is fixed by inserting it into the magazine-shaped post. After the gun is fixed, the muzzle horizontal position cannot be adjusted, and the aim cannot be corrected after clamping. Moreover, this type of test device has a magazine-shaped post that only corresponds to one type of gun, and the test device is not very versatile. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a pistol reliability shooting test bench with strong versatility and good buffering performance.

[0005] The objective of this invention is achieved as follows:

[0006] A pistol reliability shooting test bench includes a clamping mechanism and a buffer mechanism.

[0007] The clamping mechanism includes a clamping fixture base plate, and a left contour fixing plate and a right contour fixing plate disposed on the clamping fixture base plate. The left contour fixing plate is connected to the first part of the clamping mechanism. A clamping linear guide rail is disposed on the clamping fixture base plate. The right contour fixing plate is slidably fitted on the clamping linear guide rail. A clamping cylinder is connected between the left contour fixing plate and the right contour fixing plate, so that the right contour fixing plate can move towards or away from the left contour fixing plate. The right contour fixing plate is connected to the second part of the clamping mechanism.

[0008] The second part of the clamping mechanism includes a servo motor and a reducer connected to the power supply. The output shaft of the reducer extends outside the right contouring fixed plate and is connected to a reciprocating motion mechanism. The reciprocating motion mechanism is connected to a trigger push rod. The trigger push rod is perpendicular to the right contouring fixed plate. The end of the trigger push rod enters or exits the pistol trigger guard under the action of the clamping cylinder. When the end of the trigger push rod enters the pistol trigger guard, the trigger push rod can repeatedly pull the pistol trigger through reciprocating motion.

[0009] The first part of the clamping mechanism includes a left clamping template, and the second part of the clamping mechanism includes a right clamping template. The left and right clamping templates are used to clamp the grip part of the pistol and limit its vertical position under the action of the clamping cylinder.

[0010] The buffer mechanism includes a buffer fixture base plate with two parallel support plates on it. Each support plate has a buffer linear guide rail. Two parallel mounting plates are connected between the two support plates, and a sliding rod is connected between the two mounting plates. A buffer slider is slidably fitted on the sliding rod. A buffer spring is provided between the buffer slider and each of the two mounting plates, and the buffer spring is sleeved on the sliding rod. The clamping fixture base plate is fixed on the buffer slider and is also mounted on the two buffer linear guide rails via guide blocks. The clamping fixture base plate slides along the buffer linear guide rails and buffers the recoil generated by the firing of the pistol through the buffer springs.

[0011] Preferably, the reciprocating motion mechanism includes a cam fixed on the output shaft of the reducer, a push rod slider slidingly fitted on the right contour plate via a reciprocating guide rail, the trigger push rod being fixed on the push rod slider, and a connecting rod hinged between the edge of the cam and the push rod slider, so that the push rod slider can be driven to reciprocate by the rotation of the cam.

[0012] Preferably, the cam is provided with a T-shaped groove along the radial direction, and a T-shaped hinge rod is slidably fitted in the T-shaped groove. The connecting rod is hinged to the hinge rod, and the hinge rod is locked to the position on the cam by a nut, thereby adjusting the reciprocating stroke of the push rod slider.

[0013] Preferably, the left clamping contour seat and the right clamping contour seat each include an aluminum alloy fixing seat, and the aluminum alloy fixing seat is provided with a polyurethane interlayer. The polyurethane interlayer has a contour structure and can flexibly clamp the pistol grip.

[0014] Preferably, the aluminum alloy mounting base is fixed to the left / right copying mounting plate with screws, and the corresponding left and right clamping copying bases are selected according to different models of pistols.

[0015] Preferably, the clamping cylinder is equipped with a pressure regulating valve to adjust the clamping force, avoid damaging the pistol grip, and adapt to the clamping force of various pistols.

[0016] Preferably, the clamping fixture base plate of the clamping mechanism is also provided with an adjustable rod that can be raised and lowered. The top of the adjustable rod is equipped with a probe for recoil detection. The probe is used to detect whether the pistol has recoiled to the correct position and to determine the shooting malfunction. When the recoil mechanism recoils to the correct position, the pistol will touch the probe. The current circuit formed by the probe and the gun body is connected, which indicates that the recoil is complete. If there is no connection, it indicates that the recoil is not complete.

[0017] Preferably, the connecting rod is equipped with a force sensor, which monitors the magnitude of the trigger force in real time.

[0018] Preferably, the clamping cylinder is equipped with a magnetic switch to determine whether the clamping is in place.

[0019] Preferably, the first part of the clamping mechanism further includes a front end pad, which is mounted via a vertical guide rail and fixed by a set screw to adjust the height of the front end pad, which is used to support the front end of the pistol.

[0020] Because of the above-mentioned technical solution, this invention has strong versatility and good buffering performance. Attached Figure Description

[0025] See Figures 1-5 A pistol reliability shooting test bench includes a clamping mechanism, a buffer mechanism, a control system, and a fault and safety alarm system.

[0026] The clamping mechanism includes a clamping fixture base plate, and a left contour fixing plate and a right contour fixing plate disposed on the clamping fixture base plate. The left contour fixing plate is connected to the first part of the clamping mechanism. A clamping linear guide rail is disposed on the clamping fixture base plate. The right contour fixing plate is slidably fitted on the clamping linear guide rail. A clamping cylinder is connected between the left and right contour fixing plates, so that the right contour fixing plate can move towards or away from the left contour fixing plate. The right contour fixing plate is connected to the second part of the clamping mechanism.

[0027] The second part of the clamping mechanism includes a servo motor and a reducer connected to the power supply. The output shaft of the reducer extends outside the right contour plate and is connected to a reciprocating motion mechanism. The reciprocating motion mechanism is connected to a trigger push rod, which is perpendicular to the right contour plate. The end of the trigger push rod enters or exits the pistol trigger guard under the action of the clamping cylinder. When the end of the trigger push rod enters the pistol trigger guard, the trigger push rod can repeatedly pull the pistol trigger through reciprocating motion.

[0028] The first part of the clamping mechanism includes a left clamping guide seat, and the second part of the clamping mechanism includes a right clamping guide seat. The left and right clamping guide seats are used to clamp the grip part of the pistol and limit its vertical position under the action of the clamping cylinder.

[0029] The buffer mechanism includes a buffer fixture base plate with two parallel support plates on it. Each support plate has a buffer linear guide rail. Two parallel mounting plates are connected between the two support plates, and a sliding rod is connected between the two mounting plates. A buffer slider is slidably fitted on the sliding rod. A buffer spring is provided between the buffer slider and each of the two mounting plates, and the buffer spring is sleeved on the sliding rod. The clamping fixture base plate is fixed on the buffer slider and is also mounted on the two buffer linear guide rails via guide blocks. The clamping fixture base plate slides along the buffer linear guide rails and buffers the recoil generated by the firing of the pistol through the buffer springs.

[0030] The reciprocating motion mechanism includes a cam fixed on the output shaft of the reducer, a push rod slider slidingly fitted on the right contour plate via a reciprocating guide rail, and a trigger push rod fixed on the push rod slider. A connecting rod is hinged between the edge of the cam and the push rod slider, and the rotation of the cam drives the push rod slider to reciprocate. The number of rotations and frequency of the motor driving the cam can be set and adjusted according to the shooting requirements to achieve the setting of single shot, burst shot count, and burst shot frequency (shots / second).

[0031] The cam has a T-shaped groove along its radial direction, and a T-shaped hinge rod slides within the groove. The connecting rod is hinged to the hinge rod, and the hinge rod is locked to the cam by a nut, thereby adjusting the reciprocating stroke of the push rod slider. This allows for adjustment of the trigger stroke for different products.

[0032] The left and right clamping contour seats each include an aluminum alloy fixing seat, and the aluminum alloy fixing seat has a polyurethane interlayer inside. The polyurethane interlayer has a contour structure and can flexibly clamp the pistol grip.

[0033] The aluminum alloy mounting base is fixed to the left / right copy plate with screws. The corresponding left and right copy plates are selected according to the different models of pistols.

[0034] The clamping cylinder is equipped with a pressure regulating valve to adjust the clamping force, avoid damaging the pistol grip, and adapt to the clamping force of various pistols.

[0035] The clamping mechanism's clamping fixture base plate is also equipped with a height-adjustable rod. A probe for recoil detection is mounted on the top of the rod. This probe detects whether the pistol has fully recoiled, thus identifying firing malfunctions. When the recoil mechanism has fully recoiled, the pistol will touch the probe, creating a current circuit between the probe and the pistol body, indicating that the recoil is complete. If no circuit is formed, it indicates that the recoil is incomplete, stopping the pistol's firing and triggering an alarm.

[0036] The connecting rod is equipped with a force sensor, which monitors the magnitude of the trigger force in real time.

[0037] The clamping cylinder is equipped with a magnetic switch to determine whether the clamping is in place and whether it can be fired safely. If the clamping is not in place, the pistol cannot execute the firing procedure and will trigger an alarm.

[0038] The first part of the clamping mechanism also includes a front end pad, which is mounted via a vertical guide rail and fixed by a set screw to adjust the height of the front end pad. The front end pad is used to support the front end of the pistol and can adjust the angle of the pistol to a certain extent.

[0039] The first part of the clamping mechanism also includes a limiting block, which is used to limit the upper limit position of the front end of the pistol to prevent the pistol from flipping during firing.

[0040] The trigger lever is equipped with a bearing that engages with the pistol trigger.

[0041] The trigger push rod passes through the left and right contour fixing plates, which allow space for the movement of the trigger push rod.

[0042] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of the present invention.
