[0023] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0024] A rotation direction selection method for a hole on a cylinder, comprising:

[0025] A support frame 1 is provided with a slide plate 11, a No. 1 cylinder 12 is provided on the slide plate 11, and a slide plate 13 is provided on the output end of the No. 1 cylinder 12, a housing 14 is provided on the slide plate 13, a rotating motor 15 and a No. 2 cylinder 16 are provided on the side of the housing 14, and a symmetrical clamping finger 17 is provided on the output end of the No. 2 cylinder 16, and a direction selection needle 18 is provided on the opposite surface of the adjacent clamping fingers 17;

[0026] The storage bracket 2 is provided with a No. 3 cylinder 21, and the output end of the No. 3 cylinder 21 is connected to a slide 22, and a transfer member 23 is fixedly connected to the top of the slide 22, and the transfer member 23 is used to place the cylinder to be stored;

[0027] A slide rail bracket 3, on which a No. 4 cylinder 31 is installed, the output end of the No. 4 cylinder 31 is connected to a slider plate 32, and a No. 5 cylinder 33 is installed on the slider plate 32, and the output end of the No. 5 cylinder 33 is connected to a symmetrical pull rod clamp 34, and the pull rod clamp 34 is used to clamp the cylinder on the middle transmission part;

[0028] Among them, Figure 1-5 As shown, the slide plate 13 is slidably connected on the slide rail plate 11. When the No. 1 cylinder 12 is started, the slide plate 13 drives the rotating motor 15 and the No. 2 cylinder 16 to move forward and backward through the housing 14, and the No. 2 cylinder 16 can control the symmetrical clamping fingers 17 to separate or approach each other; the slide table 22 is slidably connected on the storage bracket 2, and the No. 3 cylinder 21 drives the transfer member 23 to move up and down through the slide table 22; the slider plate 32 is slidably connected on the top of the slide rail bracket 3, and the No. 4 cylinder 31 drives the No. 5 cylinder 33 and the pull rod clamp 34 to move left and right through the sliding plate, and the No. 5 cylinder 33 is used to control the symmetrical pull rod clamp 34 to separate or approach each other;

[0029] During operation, the No. 4 cylinder 31 drives the rod clamp 34 to move through the sliding plate, so that the symmetrical rod clamp 34 moves to the top of the intermediate transfer part, and then the No. 3 cylinder 21 drives the intermediate transfer part 23 to move upward through the slide 22, so that the intermediate transfer part 23 is flush with the rod clamp 34, and then the No. 5 cylinder 33 drives the symmetrical rod clamp 34 to approach, so that the symmetrical rod clamp 34 clamps the cylinder on the intermediate transfer part 23, and after clamping, the No. 3 cylinder 21 drives the intermediate transfer part 23 to return to its original position;

[0030] At the same time, driven by the No. 4 cylinder 31, the rod clamp 34 carries the cylinder to move to the clamp finger 17 and is flush with it. Then the No. 1 cylinder 12 drives the symmetrical clamp finger 17 to approach the other end of the cylinder on the rod clamp 34 through the slider and the housing 14. Then the No. 2 cylinder 16 controls the symmetrical clamp finger 17 to approach each other, so that the clamp finger 17 drives the direction selection needle 18 to contact the surface of the end of the cylinder.

[0031] Then the rotary motor 15 is started, and the rotary motor 15 drives the direction selection needle 18 to move on the surface of the end of the cylinder through the clamping finger 17. When the end of the direction selection needle 18 moves to the hole on the cylinder, the end of the direction selection needle 18 extends into the hole, so that the cylinder rotates with the rotation of the rotary motor 15. When the direction selection needle 18 rotates to a vertical state, the direction selection of the hole on the cylinder in the pull rod clamp 34 faces upward, thereby realizing the direction selection of the hole on the cylinder;

[0032] Compared with the existing circular hole orientation selection, the utility model replaces CCD photography with the orientation selection needle 18, reduces the CCD photography steps, thereby reducing the cost of cylinder processing and improving the work efficiency of subsequent cylinder processing.

[0033] As a possible implementation of this solution, preferably, Figure 1 As shown and Figure 3 As shown, a connecting rod 4 is fixedly connected to the top of the storage bracket, a U-shaped block 41 is fixedly connected to the end of the connecting rod 4, and a guide rod 42 is fixedly connected to the side of the U-shaped block 41;

[0034] The U-shaped block 41 is installed on the storage bracket through the connecting rod 4, and the guide rods 42 are installed on both sides of the top of the U-shaped block 41. When the symmetrical pull rod clamp 34 moves with the slider plate 32, the bottom of the symmetrical pull rod clamp 34 moves along the guide rod 42, thereby improving the stability of the movement of the symmetrical pull rod clamp 34.

[0035] As a possible implementation of this solution, preferably, Figure 3 As shown, a recoil block 5 is installed on the slide 22, and a buffer 51 is fixedly connected to the side of the recoil block 5 and the storage bracket;

[0036] The buffers 51 are located on both sides of the recoil block 5, and the recoil block 5 is fixedly connected to the slide 22. The recoil block 5 moves between adjacent buffers 51 to limit the movement range of the slide 22. At the same time, the buffers 51 can alleviate the impact force generated when the recoil block 5 moves and collides.

[0037] As a possible implementation of this solution, preferably, Figure 1-2 As shown, a buffer channel 6 is provided on the clamping finger 17, and a No. 1 return spring 61 is provided between the inner wall of the buffer channel 6 and the direction selection needle 18;

[0038] The direction selection needle 18 slides in the buffer channel 6, and the elasticity of the No. 1 return spring 61 reduces the scratches on the cylindrical surface by the end of the direction selection needle 18. At the same time, when the direction selection needle 18 moves to the round hole, the No. 1 return spring 61 makes the direction selection needle 18 automatically extend into the round hole, thereby reducing the steps of the symmetrical clamping fingers 17 approaching again, improving the fixing effect of the direction selection needle 18 on the cylinder and the selection efficiency of the hole on the cylinder.

[0039] As a possible implementation of this solution, preferably, Figure 4-5 As shown, a spring-pressing member 7 is disposed on the pull rod clamp 34, and a pressure plate 71 is disposed on the spring-pressing member 7, and a second return spring 72 is disposed between the spring-pressing member 7 and the pressure plate 71;

[0040] Under the action of the No. 2 reset spring 72, the spring-pressing piece 7 slides on the pull rod clamp 34 on one side, and the side surface of the spring-pressing piece 7 is opposite to the side surface of the pull rod clamp 34 on the other side. At the same time, the spring-pressing piece 7 and the pull rod clamp 34 on the other side can flexibly clamp the end of the cylinder. When the selection needle 18 moves on the surface of the cylinder, the spring-pressing piece 7 and the pull rod clamp 34 clamp the end of the cylinder. When the end of the selection needle 18 extends into the hole, the end of the cylinder will be rotatably connected between the spring-pressing piece 7 and the pull rod clamp 34, which is conducive to normal selection of the hole on the cylinder.

[0041] As a possible implementation of this solution, preferably, Figure 1 As shown, a position sensing device 8 is installed on the housing 14, and the position sensing device 8 is located between the rotating motor 15 and the No. 2 cylinder 16, and the sensing device is used to detect the rotation state of the clamping finger 17; by setting the sensing device, it is helpful to detect the rotation angle of the symmetrical clamping finger 17, thereby helping to improve the accuracy of selecting the direction of the hole on the cylinder.
