Description

Technical Field

[0002] The existing military industry generally uses manual inspection for thread go / no-go detection. A handheld thread go / no-go gauge is used to detect the go / no-go of each thread. First, the thread go / no-go gauge is inspected and the data is recorded. Then, the thread go / no-go gauge is replaced and the data is recorded. This method is inefficient, time-consuming, labor-intensive, and has safety issues. In addition, data collection is difficult. Summary of the invention

[0007] The first clamping mechanism 1, the second clamping mechanism 16 and the lifting mechanism 2 are fixed to the automatic thread detection station of the production line;

[0008] The first explosion-proof automatic feeding mechanism 8 and the second explosion-proof automatic feeding mechanism 11 are installed on two feeding guide rail transfer mechanisms 9, and the two guide rail transfer mechanisms 9 are fixed in parallel on the frame;

[0009] The first explosion-proof tightening mechanism 7 and the second explosion-proof tightening mechanism 12 are connected to the first explosion-proof automatic feeding mechanism 8 and the second explosion-proof automatic feeding mechanism 11 respectively;

[0010] The front ends of the first explosion-proof tightening mechanism 7 and the second explosion-proof tightening mechanism 12 are connected to the first explosion-proof torque sensor 5 and the second explosion-proof torque sensor 13 through the second coupling 6 and the third coupling 14 respectively;

[0014] The first explosion-proof automatic feeding mechanism 8, the second explosion-proof tightening mechanism 7 and the lifting mechanism 2 are reset to perform thread-stop detection, and the projectile is clamped by the second clamping mechanism 16 and the lifting mechanism 2. Then the second explosion-proof automatic feeding mechanism 11 drives the second explosion-proof tightening mechanism 12 to complete the automatic feeding action, and the second explosion-proof tightening mechanism 12 drives the stop gauge 15 to rotate to complete the rotational tightening action. The tightening action is controlled through the feedback of the second explosion-proof torque sensor 13 to complete the detection of the projectile thread-stop.

[0031] In order to make the purpose, content and advantages of the present invention more clear, the specific implementation methods of the present invention are further described in detail below in conjunction with the drawings and examples.

[0032] The present embodiment provides a mechanism for passing and stopping the thread of the ammunition detection port, comprising: a first clamping mechanism 1, a lifting mechanism 2, a go gauge 3, a first coupling 4, a first explosion-proof torque sensor 5, a second coupling 6, a first explosion-proof tightening mechanism 7, a first explosion-proof automatic feeding mechanism 8, a feeding guide rail transfer mechanism 9, an electrical system 10, a second explosion-proof automatic feeding mechanism 11, a second explosion-proof tightening mechanism 12, a second explosion-proof torque sensor 13, a third coupling 14, a stop gauge 15, a second clamping mechanism 16, and a fourth coupling 17;

[0033] The first clamping mechanism 1, the second clamping mechanism 16 and the lifting mechanism 2 are fixed to the automatic thread detection station of the production line;

[0034] The first explosion-proof automatic feeding mechanism 8 and the second explosion-proof automatic feeding mechanism 11 are installed on two feeding guide rail transfer mechanisms 9, and the two guide rail transfer mechanisms 9 are fixed in parallel on the frame;

[0035] The first explosion-proof tightening mechanism 7 and the second explosion-proof tightening mechanism 12 are connected to the first explosion-proof automatic feeding mechanism 8 and the second explosion-proof automatic feeding mechanism 11 respectively;

[0036] The front ends of the first explosion-proof tightening mechanism 7 and the second explosion-proof tightening mechanism 12 are connected to the first explosion-proof torque sensor 5 and the second explosion-proof torque sensor 13 through the second coupling 6 and the third coupling 14 respectively;

[0037] The first explosion-proof torque sensor 5 is connected to the go gauge 3 via the first coupling 4, and the second explosion-proof torque sensor 13 is connected to the stop gauge 15 via the fourth coupling 17;

[0038] The electrical system 10 is fixed under the frame.

[0039] The first clamping mechanism 1 and the lifting mechanism 2 hold the projectile tightly, and the first explosion-proof automatic feeding mechanism 8 drives the explosion-proof tightening mechanism 7 to complete the automatic feeding action, and then the rotation of the explosion-proof tightening mechanism 7 drives the through gauge 3 to rotate, and the rotation tightening action is completed. The first explosion-proof torque sensor 5 feedbacks and controls the tightening action to complete the detection of the projectile thread-through;

[0040] The first explosion-proof automatic feeding mechanism 8, the second explosion-proof tightening mechanism 7 and the lifting mechanism 2 are reset to perform thread-stop detection, and the projectile is clamped by the second clamping mechanism 16 and the lifting mechanism 2. Then the second explosion-proof automatic feeding mechanism 11 drives the second explosion-proof tightening mechanism 12 to complete the automatic feeding action, and the second explosion-proof tightening mechanism 12 drives the stop gauge 15 to rotate to complete the rotational tightening action. The tightening action is controlled through the feedback of the second explosion-proof torque sensor 13 to complete the detection of the projectile thread-stop.

[0041] The stop gauge 15 detects the torque overrun through the second explosion-proof torque sensor 13 and the pulse of the servo motor to record the number of threads screwed into the thread, completes the automatic spring-mouth thread through-and-through detection, and records the data.

[0042] This mechanism usually works by combining mechanical structure with sensor technology. When the bullet-mouth part to be inspected is placed in a specific position, the inspection gauge in the mechanism will reverse to find the starting section of the thread, and then rotate forward to automatically screw into the bullet-mouth thread. At the same time, the explosion-proof tightening mechanism has an axial floating device, and the explosion-proof automatic feeding mechanism has left and right, up and down floating devices to ensure that the gauge has a floating function and can smoothly enter the thread. If the thread size and shape meet the standards, the gauge can be screwed in smoothly and trigger the through-end detection torque sensor and position detection sensor, indicating that the thread through-end is qualified. On the contrary, if the gauge encounters obstacles during the screw-in process, the torque sensor feedback torque exceeds the limit or cannot be screwed in to the specified depth, then the thread through-end is judged to be unqualified.

[0043] When checking the stop, use another gauge that is slightly larger to try to screw in the thread. If the gauge cannot be screwed in or can only be screwed in to a certain depth before getting stuck, the thread stop is qualified; if the gauge is screwed in too much, the thread stop is judged to be unqualified.

[0044] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
