The special-shaped piston 4 is longitudinally penetrated by a channel 23. A spring 19 is provided between the upper part of the special-shaped piston 4 and the gun body 3. The lower part of the channel 23 is provided with a continuously arranged bent annular surface 9 and an arcuate annular surface 21; the lower part of the gun body 3 extends into the special-shaped piston 4, and the lower part of the gun body 3 is provided with a plurality of ball head holes 18 in an annular array; the upper part of the gun head 1 extends into the interior of the gun body 3, the upper end of the gun head 1 is circumferentially recessed inwardly and provided with a groove 20, and the lower part of the gun head 1 extends into the gun changing seat 2 and is positioned by the gun changing seat 2; two outlets 22 are provided in the gun head 1, one outlet 22 is arranged longitudinally and the other outlet 22 is arranged transversely; a plurality of steel balls 16 are correspondingly arranged in the ball head holes 18, and the plurality of steel balls 16 can be movably arranged in the groove 20 under the pressure of the bent annular surface 9 and the arcuate annular surface 21, so that the gun body 3 and the gun head 1 are in a locked state or an unlocked state.

[0036] In a preferred embodiment, the longitudinal inclination angle of the upper portion of the bent annular surface 9 is a, and the longitudinal inclination angle of the lower portion of the bent annular surface 9 is b. The diameter of the arc-shaped annular surface 21 is the same as that of the steel ball 16.

[0037] During actual use, the gun body 3 is inserted into the channel 23 of the shaped piston 4. The shaped piston 4, through compressed air, amplifies the force applied to the steel ball 16 at a suitable angle a, compressing the gun head 1 into contact with the gun body 3. Adjacent to the pressure angle is a negative angle b, ensuring self-locking in the event of an accident. Further connected is a release zone arcuate annular surface 21, with a radius corresponding to the steel ball 16, ensuring sufficient clearance for the steel ball 16 to escape with minimal linear displacement.

[0038] Furthermore, the gun head 1 is positioned by changing the gun holder 2 so that the gun head 1 can be quickly replaced.

[0039] A rotary gun head switching system includes the above-mentioned multi-channel rotary gun head quick-change structure and a gun changing seat 2.

[0040] A mounting groove 5 is provided on the gun changing seat 2, and an X-direction sensor 6 is provided on the inner wall of the mounting groove 5 along the first direction, and a Y-direction sensor 7 is provided on the inner wall of the mounting groove 5 along the second direction; at least one inner wall of the mounting groove 5 is provided with a plurality of positioning blocks 8; a positioning groove 10 is provided on the outer wall of the gun head 1, and the gun head is installed in the mounting groove 5, and the X-direction sensor 6 and the Y-direction sensor 7 are both facing the gun head 1, and the positioning block 8 can be clamped in the positioning groove 10.

[0041] During actual use, two sensors are provided on the gun changing seat 2. The X-direction sensor 6 is installed in the gun changing seat 2 along a first direction, which is the width direction of the gun changing seat 2. The Y-direction sensor 7 is installed in the gun changing seat 2 along a second direction, which is the length direction of the gun changing seat 2. The directions of the X-direction sensor 6 and the Y-direction sensor 7 are arranged vertically. The two vertically arranged sensors can detect the position of the gun head 1 from two directions and detect whether the gun head 1 is in a predetermined position. The position of the gun head 1 can be positioned by the positioning block 8. The gun changing seat 2 can position and clamp the gun head 1, so that the gun head 1 can be quickly replaced from the gun body 3.

In addition, the ball studs cooperate with the positioning grooves of the gun head 1 to achieve flexible positioning, compensating for the robot's motion accuracy and process debugging deviations.

[0047] Furthermore, a multi-channel rotating gun head quick-change structure is provided, wherein the two opposite side walls of the positioning groove 5 are provided with a limiting step 15. Specifically, the limiting step 15 is provided on the gun changing seat 2 to prevent the gun head 1 from being damaged by robot or human error.

[0048] Furthermore, a multi-channel rotating gun head quick-change structure is provided, wherein the second stepped portion 12 is provided with a plurality of mounting holes.
