The tail part of the rocket gun barrel is provided with a locking body with a special structure, as shown in figures 1 and 2, the locking body comprises two locking plates which are symmetrically arranged in parallel and respectively comprise a first locking plate 11 and a second locking plate 12. Contain the clearance between two locking plates, the tip of two locking plates is all inwards bent and is constituted an annular structure, and the centre of two locking plates is connected through a fastening bolt 12 that runs through, and space department between two locking plates still includes a card strip 14, card strip 14 also with fastening bolt 12 fixed connection, and card strip 14 upwards extends to the other end from the one end slope of locking body. The unlocking action of the locking body is to break the locking plates, and the locking plates move to the outside of the two locking plates from the annular area between the two locking plates.
When weapons such as artillery and the like are used, if the unlocking force of the locking body cannot meet the requirement, the normal use of the rocket artillery is possibly influenced, so that the unlocking force of the unlocking action of the locking body needs to be regularly detected. When the locking body leaves a factory, a manufacturer can manually detect the unlocking force of the locking body through tension measurement. The detection efficiency is low, and the detection precision is insufficient. At present, no special equipment for measuring the unlocking force of the locking body exists, and no detection tool capable of directly detecting the unlocking force of the locking body used for installation on a rocket gun exists.

In this technical solution, the measurement tube 2 and the first and second lumens 21 and 22 therein are not limited in shape and size, and the cross section may be square, circular or polygonal, or may be in other shapes. In the present embodiment, the measuring tube 2 is designed as a square tubular structure, and the first lumen 21 and the second lumen 22 are coaxial cylindrical cavities. In the technical solution, the relative positions of the first opening 24 and the second opening 25 are not limited, and the embodiment considers the convenience of the parts processing and the device measurement in use, and the first opening 24 and the second opening 25 are arranged at symmetrical positions on the outer wall of the measuring pipe 2.
As shown in fig. 3, the unlocking body 3 is installed in the first lumen 21, and the shape of the outer contour of the unlocking body 3 matches with the first lumen 21. The periphery of the unlocking body 3 also comprises a first unlocking tongue 31 and a second unlocking tongue 32 which protrude outwards. The first opening tongue 31 and the second opening tongue 32 extend out of the first lumen 21 along the first opening 24 and the second opening 25, respectively, on the inner wall of the measurement pipe 2. And the lengths of the first and second unlocking tongues 31 and 32 are shorter than the lengths of the first and second openings 24 and 25.
The jacking mechanism 4 comprises a push rod 41 and a jacking block 42, and the jacking block 42 is connected to the end part of the push rod 41; the section of the top block 42 is larger than that of the push rod 41; with the top block 42 located within the first lumen 21 and the pushrod 41 located within the second lumen 22.
The pressure sensor 5 is arranged on one side of the unlocking body 3 close to the top block 42; the top piece 42 first comes into contact with the pressure sensor 5 when approaching the unlocking body 3.
An off-line locking mechanism 6 is located on the outer wall of the measuring tube 2 near the first opening 24 for locking the lock body 1 when it is removed. When the locking body 1 is locked on the off-line locking mechanism 6, the first unlocking tongue 31 is just inserted into the two locking plates in the locking body 1, and the unlocking action of the locking body 1 can be completed when the first unlocking tongue 31 moves along the first opening 24.
As shown in fig. 5, the offline locking mechanism 6 includes a pressing plate 63, a lock pin 64, and a first stopper groove 61 and a second stopper groove 62. The first limiting groove 61 and the second limiting groove 62 are both U-shaped grooves; the first limiting groove 61 and the second limiting groove 62 are distributed along the extension direction of the measuring pipe 2; the first opening 24 is located between the first and second retaining grooves 61, 62; the pressing plate 63 is fixedly connected with the upper opening of the first limiting groove 61, and when the locking body 1 and the off-line locking device are installed in a locking mode, two ends of the locking body 1 are respectively clamped into the two limiting grooves. Lock holes with opposite positions are arranged on the side plates at the two sides of the second limit groove 62; the second limit groove 62 locks the lock body 1 by a detachable locking pin 64.
The mechanical limiting mechanism 26 is located on the outer wall of the measuring tube 2 and close to the second opening 25, and the mechanical limiting mechanism 26 is used for clamping the measuring tube 2 on the artillery. After the measuring tube 2 is clamped with the artillery, the second unlocking bolt 32 is just inserted into the locking body 1, and the first unlocking bolt 31 can complete the unlocking action of the locking body 1 when moving along the first opening 24.
As shown in fig. 6, the mechanical limiting mechanism 26 is a limiting member having a bent portion, and a connecting line between the limiting member and the second opening 25 is parallel to the extending direction of the measuring pipe 2. The locating part is located survey one section that is close to the second cavity on buret 2 outer wall, and the direction of bending of the portion of bending in the locating part points to the one side of keeping away from the seal end on surveying buret 2. The spacing between the limiting member and the second opening 25 satisfies: when the limiting piece is connected with a connecting hole or a connecting piece near the locking body 1 on the gun barrel, the second unlocking tongue 32 is just inserted into the insides of the two locking pieces in the locking body 1.
The pushing mechanism 7 is used for controllably applying pressure to the push rod 41 in the measurement pipe 2 to move the push rod 41 to the side close to the unlocking body 3. In this embodiment, the pushing mechanism 7 is an electrically controlled telescopic device, and the electrically controlled telescopic device includes a telescopic shaft; all components except the push-out mechanism 7 in the detection device of the dual-purpose gun locking body 1 form a measurement mechanism; when the pushing mechanism 7 is connected with the measuring mechanism, the telescopic shaft is coaxial with the push rod 41, and the telescopic shaft and the push rod are connected or abutted.
The controller 8 is used for receiving the detection value of the pressure sensor 5 and/or controlling the pushing-out mechanism 7 to apply pressure to the push rod 41, and recording the maximum pressure value recorded by the pressure sensor 5 when the pushing-out mechanism 7 performs the pressing action every time, and taking the maximum pressure value as the value of the unlocking force.
The following further describes in detail a dual-purpose artillery locking body 1 detection device provided in this embodiment, in combination with two operation modes, i.e., offline measurement and online measurement of the locking body 1.
In the off-line measurement mode, an operator pulls out the lock pin 64 out of the second limit groove 62, inserts one end of the locking body 1 into the lower portion of the pressure plate 63 in the first limit groove 61, and inserts the other end of the locking body into the second limit groove 62, and then inserts the lock pin 64 from the lock hole on the side surface of the second limit groove 62 to fix the locking body 1. After assembly is complete, as shown in fig. 7. The side of the locking body 1 is in a shuttle shape, when the locking body 1 is tightly clamped by the pin shaft and thrust is applied to the second limit groove 62 to unlock, two lock pieces of the locking body 1 can expand towards two sides to be opened, but the locking body 1 does not slide. I.e. the off-line locking mechanism 6 performs a locking function. Considering that the side of the locking body 1 is in a shuttle shape, the off-line locking mechanism 6 in this embodiment may be replaced by two collars which can be turned, detached or moved in a sliding manner, as shown in fig. 8, when the locking body 1 is placed at a predetermined position, the middle position of the locking body 1 is clamped by the limiting ring 60, since the middle of the locking body 1 is wider and both sides are narrower, even if the locking body 1 is pushed in a direction parallel to the extending direction of the locking body 1, the limiting ring 60 locks the locking body 1, and the larger the force applied to the locking body 1 is, the tighter the limiting ring 60 locks.
After the locking body 1 is fixed, an operator opens the push-out mechanism 7, the telescopic shaft extends out of the push-out mechanism 7, the push rod 41 and the ejector block 42 are driven to move forwards, after the ejector block 42 is in contact with the pressure sensor 5, pressure is applied to the unlocking shaft at the same time, and the detection value of the pressure sensor 5 is increased continuously in the process. The first unlocking tongue 31 in the unlocking body 3 applies pressure to the two locking plates of the locking body 1 at the same time, and when the output of the push-out mechanism 7 enables the acting force applied by the unlocking body 3 to reach the unlocking force of the locking body 1, the unlocking tongue breaks through the two locking plates of the locking body 1, and the unlocking action is completed. At this time, the first unlocking tongue 31 does not receive a resistance action any more, when the unlocking body 3 receives a thrust action of the push rod 41 and the top block 42, the unlocking body 3 can move forward, the first unlocking tongue 31 and the second unlocking tongue 32 can also continue to slide forward for a certain length of stroke along the first opening 24 and the second opening 25, and a detection value on the pressure sensor 5 also rapidly decreases. At this time, the operation of the push-out mechanism 7 is stopped, and the process of measuring the unlocking force of the locking body 1 is completed. Upon receipt of this signal, the controller 8 uses the maximum measured value recorded by the pressure sensor 5 during this measurement as the value of the unlocking force of the lock body 1.
In the on-machine measurement mode, as shown in fig. 9, an operator inserts the measuring tube 2 in the detection device of the locking body 1 into the locking body 1 at the tail of the gun barrel, then inserts the limiting piece into the connecting hole near the gun locking body 1, tightly clamps the gun and the measuring tube 2 through the hook-shaped limiting piece, and after the connection is completed, the second unlocking tongue 32 from the second opening 25 is inserted into the locking body 1 outside the gun barrel, so that the connection between the detection device of the gun locking body 1 and the gun is completed.
Next, the operator opens the push-out mechanism 7 of the detection device in the same way as in the offline measurement mode, opens the lock body 1 through the second open latch 32, and measures the value of the opening force of the lock body 1.
In the present embodiment, in order to improve the stability of the detection device, the outer diameter of the push rod 41 in the present embodiment is matched with the inner diameter of the second lumen 22, so that the push rod 41 can only move along the extending direction of the second lumen 22, and the lateral displacement of the push rod 41 during the movement process is limited. The outer diameters of the rest parts of the first unlocking tongue 31 and the second unlocking tongue 32 at the unlocking body 3 are also matched with the first tube cavity 21.
The push-out mechanism 7 in this embodiment is manually operated, and the push-out mechanism 7 is similar in structure to a conventional electric drilling tool and similar in function to an electric cylinder. The operator controls the output of the pushing mechanism 7 through a switch. And the controller 8 records only the detection value of the pressure sensor 5 during the measurement and determines the value of the unlocking force based on the change in the measurement value.
In addition, in other embodiments, the pushing-out mechanism 7 may be automatically operated by the controller 8, the operator gives a measurement instruction to the controller 8 only through the switch, and then the controller 8 turns on the pushing-out mechanism 7, and the controller 8 turns off the pushing-out mechanism 7 immediately after the detected value obtained by the pressure sensor reaches the maximum and continues to fall, and outputs the detected value of the unlocking force.
In the measuring tube 2 of the detecting device of the gun locking body 1 in the embodiment, a reset cavity 23 is further arranged on one side of the tail end of the second tube cavity 22 far away from the first tube cavity 21; the reduction lumen 23 has a larger inner diameter than the second lumen 22. The reset cavity 23 is internally provided with a reset elastic part 9, the reset elastic part 9 generates elastic deformation when the push rod 41 moves towards the first lumen 21, and after the pushing mechanism 7 cancels the pushing force, the push rod 41 moves towards the second lumen 22 and restores to the initial state.
Specifically, in this embodiment, a limiting piece is disposed on the other end of the push rod 41 away from the top block 42, and the outer diameter of the limiting piece is greater than that of the push rod 41; the elastic restoring element 9 is a cylindrical spring sleeved on the outer side of the push rod 41, one end of the cylindrical spring abuts against the inner wall of the restoring cavity 23, and the other end of the cylindrical spring abuts against the limiting piece.
In the embodiment, a cylindrical spring is used as the return elastic member 9, and after the measurement is finished and the telescopic shaft of the push-out mechanism 7 is retracted, the push rod 41 is pulled back again by the return elastic member 9, so that the top block 42 and the pressure sensor 5 are out of contact. The reset elastic piece 9 solves the problem that the push rod 41 can not be effectively retracted when the push rod 41 and the telescopic shaft in the push-out mechanism 7 are in butt joint instead of direct fixed connection.
In this embodiment, in a natural state, a gap is provided between the top block 42 and the pressure sensor 5; when the push rod 41 is not subjected to the pushing force of the pushing mechanism 7, the top block 42 is not in contact with the pressure sensor 5. The clearance is provided to keep the top block 42 and the pressure sensor 5 disengaged in the non-operating state. Thereby reducing the damage that continued pressure action causes to the sensitivity of the pressure sensor 5. At the same time, the gap allows the push rod 41 to move to contact with the pressure sensor 5, and a space exists between the push rod and the pressure sensor. From the detection result of the pressure sensor 5, the detection result of the pressure sensor 5 is 0 in the stroke of the push rod 41, and after the idle stroke is finished, the pressure applied by the top block 42 is increased and the detection value of the pressure sensor 5 is also increased as the pushing mechanism 7 outputs the pushing force action. When the critical state of the unlocking force is reached, the detection value of the pressure sensor 5 reaches the maximum, and then the unlocking action is completed, and the pressure sensor 5 reaches the maximum. After the pushing mechanism 7 stops working, the telescopic rod retracts, the push rod 41 also completes resetting, and the indication value of the pressure sensor 5 is restored to 0 at the moment. The indication of the pressure sensor 5 is increased from 0 to a maximum value and then reduced again to 0, and a complete measuring cycle of the detection device of the gun lock 1 is carried out.
Example 2
This embodiment provides a detection device for a dual-purpose gun lock 1, which is different from embodiment 1 in that: as shown in fig. 10 and 11, the unlocking body 3 in this embodiment is provided with at least one limiting rod 33 extending toward the top block 42, and a position on the top block 42 near the periphery is provided with a limiting hole for the limiting rod 33 to penetrate through; the stopper rod 33 is parallel to the extending direction of the push rod 41.
The limiting rod 33 in this embodiment is equivalent to a guide rod, and the rod can make the movement direction of the top block 42 have directivity; and can move only in a direction of contacting or separating with the unlocking body 3 of the target area. Further illustrating the lateral displacement during the telescoping movement of the pushrod 41.
The number of the stopper rod 33 is one in this embodiment. In other embodiments, the number of the limiting rods 33 can be increased as required.
The joint of the top block 42 and the push rod 41 is provided with a limiting sleeve 43, and the outer diameter of the limiting sleeve 43 is larger than the inner cavity of the second tube cavity 22 and smaller than the inner diameter of the first tube cavity 21. The limiting holes are distributed at least in an annular area of the top block 42, which is closer to the periphery than the limiting sleeve 43.
The limiting sleeve 43 plays a role in buffering when the push rod 41 retracts, so that the top block 42 is prevented from being in direct contact with the inner walls of the transition positions of the first tube cavity 21 and the second tube cavity 22, and the top block 42 and the push rod 41 are prevented from being broken and damaged due to impact force of resilience. The limiting hole is arranged at a position which is more outward than the limiting sleeve 43, so that the limiting rod 33 can be blocked by the limiting sleeve 43 after penetrating through the top block 42 in the process that the push rod 41 moves towards the unlocking body 3, and the interference between the limiting rod and the top block is reduced.
