[0037] The specific shape, length, curvature, etc. of the support platform 11 are customized according to the processing requirements of the production line to ensure the stability of the inner ring transmission chain and the outer ring transmission chain of the power device 2 during the rotation process.

[0038] In the specific embodiment of the present invention, see Figure 1-Figure 7 , further comprising a power mechanism 2, wherein the power mechanism 2 is mounted on the annular support frame 1;

[0039] The power mechanism 2 further includes a power motor 21, a first transmission belt 22, a first transmission shaft 23, a second transmission belt 24, an inner ring transmission chain 25, a second transmission shaft 26 and an outer ring transmission chain 27;

[0040] A motor support platform 121 is provided on the support leg 12. The power motor 21 is provided on the motor support platform 121 at the bottom of the annular support frame 11. The power motor 21 is positioned in the center or slightly to the outside, and the output shaft of the power motor 21 is vertically upward.

[0041] The first transmission shaft 23 and the second transmission shaft 26 are both rotatably mounted on the protruding portions on both sides of the motor support platform 121 of the annular support frame 11;

[0042] The first transmission belt 22 is simultaneously mounted on the output shaft of the power motor 21 and the first transmission shaft 23. The first transmission shaft 23 is mounted with a first transmission gear plate 231. The inner ring transmission chain 25 is mounted on the inner circumference of the annular support frame 11.

[0044] When the power motor is working, it drives the first transmission shaft and the second transmission shaft to rotate; at the same time, the first transmission shaft drives the first transmission sprocket to rotate, and the second transmission shaft drives the second transmission sprocket to rotate; then the first transmission sprocket drives the inner ring transmission chain to rotate, and the second transmission sprocket drives the outer ring transmission chain to rotate; at the same time, the outer ring transmission chain and the inner ring transmission chain are set to corresponding lengths to achieve synchronous rotation of the inner ring transmission chain and the outer ring transmission chain, thereby driving the tooling trolley to move and achieving synchronous movement of the inner and outer sides of the tooling trolley.

[0045] In the specific embodiment of the present invention, see Figure 1-Figure 7 , also includes a tooling trolley 3 and a complex mechanism 4;

[0046] The tooling trolley 3 is equipped with a fixture, which is used to transport the workpiece and can be equipped with a corresponding fixture;

[0047] The tooling trolley 3 is connected to the power mechanism 2, and the power mechanism 2 drives the tooling trolley 3 to move, thereby realizing the flow between different processing stations;

[0048] The coupling mechanism 4 is mounted on the annular support frame 11; the tooling trolley 3 is docked with the coupling mechanism 4; a transport base 31 is provided at the bottom of the tooling trolley 3;

[0049] The reconnection mechanism 4 includes a reconnection cylinder 41, a reconnection block 42 and a reconnection slot 43;

[0050] A multiple-coupling cylinder support platform 13 is provided on the annular support frame 11, and the multiple-coupling cylinder 41 is installed on the multiple-coupling cylinder support platform 13 of the annular support frame 11, with the pneumatic rod of the multiple-coupling cylinder 41 facing upward, and the multiple-coupling block 42 is installed on the top of the pneumatic rod of the multiple-coupling cylinder 41, and the multiple-coupling groove 43 is provided at the bottom of the conveying base 31, and the multiple-coupling block 42 is docked with the multiple-coupling groove 43;

[0052] The bottom end of the transport base 31 is provided with a clamping block 32, and the clamping block 32 is docked with the clamping groove 282;

[0053] There are gaps between the conveying blocks 281 to facilitate movement on the annular support frame 11;

[0054] During operation, the inner ring transmission chain and the outer ring transmission chain simultaneously drive their respective transmission blocks to move, and the transmission blocks drive the transport base to move, thereby driving the entire tooling trolley to move.

[0055] In the specific embodiment of the present invention, see Figure 1-Figure 7 A tightening mechanism 5 is installed in the clamping groove 282, and the tightening mechanism 5 includes a micro-top cylinder 51, a top block 52 and a limiting groove 53;

[0058] When the tooling trolley is re-docked onto the conveying block, the micro-lifting cylinder drives the top block to move forward, so that the top block docks with the limit groove, thereby limiting the tooling trolley and ensuring that the tooling trolley moves forward steadily during the conveying process.

[0059] In the specific embodiment of the present invention, see Figure 1-Figure 7 The length of the clamping groove 282 is greater than the length of the clamping block 32, and a travel distance is reserved for speed to ensure that the clamping is in place;

[0061] The width of the clamping slot is greater than or equal to the width of the clamping block, and is generally slightly greater, to ensure that the clamping block can be clamped into the clamping slot.

[0062] In the specific embodiment of the present invention, see Figure 1-Figure 7 The coupling groove 43 is a connecting groove with an opening on one side, which provides a sliding space for the coupling block 42. A distance sensor can be set on the inner wall of the coupling groove. When the distance sensor senses that the coupling block is approaching, the coupling cylinder 41 moves upward to lift the entire tooling trolley.

[0064] In the specific embodiment of the present invention, see Figure 1-Figure 7 In this application, after the tooling trolley is lifted up, the stability is not enough just by relying on the support of the composite block. An auxiliary connection mechanism is also provided on the processing equipment to provide the tooling trolley with stable support, which is convenient for subsequent work.

[0065] In the specific embodiment of the present invention, see Figure 1-Figure 7 When working, the power mechanism drives the inner ring transmission chain and the outer ring transmission chain to rotate at the same frequency, and then drives the transmission block to rotate at the same frequency to transport the tooling trolley forward stably;

[0066] When the tooling trolley reaches the operating station, the coupling mechanism works to lift the entire tooling trolley up;

[0067] After the work brought to the workstation is completed, the reconnection mechanism returns to its original position, and the tooling trolley is connected to the conveying block again and transported forward;

[0068] During the whole process, the inner ring transmission chain and the inner ring transmission chain will not stop working, and will not affect the normal transmission of the tooling trolley.

[0069] The work of the compound cylinder includes:

[0070] 1. Stay in the original position and wait for work. The highest position of the original position is lower than the lowest position of the transport base of the tooling trolley;

[0071] 2. Set the distance X1 upward, which is the distance from the top surface of the multi-connection block to the top of the multi-connection slot;

[0072] 3. Continue to push upwards to a set distance X2, which is greater than the thickness of the card slot;

[0073] 4. Retract downward to a set distance y, which is greater than or equal to the sum of X1 and X2, and wait for the next work.

[0074] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
