[0029] The detection mechanism 4 is arranged on the upper side wall of the base 1 at the side of the positioning column 31, and is used to detect whether the position of the product 2 on the base 1 is correct. The detection mechanism 4 comprises a guide rail 41 fixedly arranged on the upper side wall of the base 1. The upper side wall of the guide rail 41 is provided with a sliding groove 411. A moving block 42 is slidingly arranged in the sliding groove 411. The sliding groove 411 limits the transverse movement of the moving block 42 along the axis direction of the sliding groove 411. The axis of the track in the sliding groove 411 for the sliding of the moving block 42 passes through the axis of the positioning column 31. The moving block 42 is fixedly connected with a positioning pin 421 at the end close to the positioning column 31. The positioning pin 421 is wedge-shaped, and the end close to the positioning column 31 is triangular in shape. The other end of the moving block 42 extends to the outside of the sliding groove 411 and is fixedly connected with a trigger rod 422. Meanwhile, a sensor 12 is fixedly arranged on the side of the base 1 close to the guide rail 41. The sensor 12 is arranged at the position of the base 1 away from the positioning column 31. The sensor 12 is electrically connected with the punching device through a signal transmission line. When the operator pushes the moving block 42 to be close to the positioning column 31, if the end of the positioning pin 421 away from the moving block 42 can be inserted into the inside of the notch 21, the inclined surface on the triangular end of the positioning pin 421 will be in contact with the side wall of the notch 21. In the process of the relative sliding between the side wall of the notch 21 and the inclined surface, the product 2 will slightly rotate, so that the detection mechanism 4 can finely adjust the position of the product 2. When the inclined surfaces on both sides of the positioning pin 421 are in contact with the side wall of the notch 21, the positioning pin 421 cannot continue to move towards the positioning column 31. The notch 21 cooperates with the positioning pin 421 to limit the rotation of the product 2, so that the product 2 is in the correct processing position. At this time, the trigger rod 422 moves to the upper side of the sensor 12. The sensor 12 lights up a green light due to the sensing of the trigger rod 422, so as to judge that the position of the product 2 is correct. Meanwhile, the sensor 12 sends an electric signal to the punching device to start the punching device to accurately punch the product 2. If the end of the positioning pin 421 away from the moving block 42 cannot be inserted into the inside of the notch 21, the trigger rod 422 cannot move to the upper side of the sensor 12. The sensor 12 lights up a red light due to the failure to sense the position of the trigger rod 422, so as to remind the operator to adjust the position of the product 2, so as to avoid the misplacement of the product 2 and improve the punching quality of the punching device on the product 2.

[0030] In order to facilitate the operator to move the moving block 42, the positioning pin 421 and the trigger lever 422 to the direction close to the positioning column 31, the detection mechanism 4 further comprises a cover plate 43 fixedly arranged on the upper side wall of the guide rail 41, the cover plate 43 is an inclined L-shaped structure, the vertical section of the cover plate 43 is located on the side of the inductor 12 away from the base 1, the horizontal section of the cover plate 43 is fixed on the upper side wall of the guide rail 41, the lower side wall of the vertical section of the cover plate 43 is provided with a through slot 431, the upper side wall of the moving block 42 is in sliding contact with the lower side wall of the cover plate 43, the same pull rod 44 is threadedly connected on the moving block 42 and the trigger lever 422, one end of the pull rod 44 away from the moving block 42 penetrates through the through slot 431 and is fixed with a round head, the detection mechanism 4 further comprises a spring 45 arranged between the trigger lever 422 and the vertical section of the cover plate 43, the spring 45 is sleeved on the pull rod 44, the spring 45 drives the moving block 42 to close to the positioning column 31, the operator holds the round head to pull the pull rod 44 to the direction away from the positioning column 31, so that the pull rod 44 drives the moving block 42, the positioning pin 421 and the trigger lever 422 to synchronously move away from the positioning column 31, at this time the spring 45 is elastically contracted, the product 2 is placed on the base 1 again, the position of the gap 21 is adjusted, so that the gap 21 is arranged to the direction close to the detection mechanism 4, then the operator releases the pull rod 44, the compressed spring 45 begins to relax, the relaxed spring 45 drives the moving block 42, the positioning pin 421 and the trigger lever 422 to close to the positioning column 31, so that the positioning pin 421 automatically contacts the product 2 to complete the detection of the position of the product 2, ensures that the product 2 is placed on the correct punching processing position, so as to improve the detection efficiency of the operator on the placement position of the product 2.

[0031] The device in use, first pull rod 44 to the direction away from the positioning column 31 pull, make positioning pin 421 and positioning column 31 between the spacing is sufficient to place product 2, and then product 2 is set on the positioning column 31, then product 2 is rotated around the axis of positioning column 31, to adjust the position of the gap 21, make gap 21 set towards the detection mechanism 4, then release the pull rod 44, make the relaxed spring 45 push positioning pin 421 contact product 2, if positioning pin 421 can be inserted into the inside of gap 21, positioning pin 421 will product 2 fine to the correct placement position, trigger lever 422 moves to inductor 12, at this time inductor 12 judge product 2 placement position is correct, rotate the shaft 32 until the end plate on the two pressure plate 33 product 2 is pressed down, product 2 is fixed on the base 1, after that, the punching equipment can be accurate punching on product 2, if positioning pin 421 can not be inserted into the inside of gap 21, inductor 12 judge product 2 placement position is wrong, at this time the operator will product 2 around the positioning column 31 rotation, re align the gap 21 positioning pin 421, repeat the above steps until positioning pin 421 can be inserted into the inside of gap 21, when product 2 on the base 1 placement position is correct, the operator rotates the shaft 32 until the two pressure plate 33 product 2 is pressed towards the base 1, product 2 is tightly fixed on the base 1, avoid product 2 position changes again, can make the punching equipment accurate punching on product 2.
