[0015] The following is combined with Figure 1 -Attached Figure 4 This application is described in further detail.
[0016] Example 1:
[0017] A calibration mechanism for a cutting plotter, referring to Figure 1-4 , including a machine 1, a lettering system 2, two clamping members 41 and two driving members 46. The lettering system 2 is slidably installed on the top of the machine 1. The lettering system 2 consists of a movable frame, a control head, a carving knife and three sets of electric guide rails. A pad 3 is welded in the middle of the top of the machine 1. After the plate to be engraved is placed on the top of the pad 3, the computer will control the control system pre-set in the lettering system 2. The control system controls the three sets of electric guide rails to drive the movable frame and the control head to move, thereby realizing three-dimensional movement. During the three-dimensional movement, the carving knife in the lettering system 2 can engrave the plate. The two clamping members 41 are both located above the pad 3, and the bottom of the two clamping members 41 One end of each part is provided with a rectangular groove, and the other end of the top of each of the two clamping parts 41 is provided with an arc groove. Two limit plates 42 are fixedly installed at both ends of the top of the machine 1 through four mounting parts 5. The mounting parts 5 are composed of a mounting block 51 and a bolt 52. The mounting block 51 is welded to one side of the limit plate 42, and the bolt 52 threadedly penetrates the mounting block 51. The bolt 52 is threadedly connected to the side wall of the machine 1, thereby fixing the limit plate 42 and the machine 1. There is a movable block 43 sliding inside the two limit plates 42, and the two sides of the two movable blocks 43 are respectively fitted with the two inner side walls of the two limit plates 42. One end of the top of the two movable blocks 43 is provided with a socket. A limiting column 44 is welded to the middle part of the top of the movable block 43, and the two clamping members 41 are movably sleeved on the outside of the two limiting columns 44, so that the two clamping members 41 can rotate above the pad 3. If the rectangular plate is to be calibrated and positioned, the two clamping members 41 are rotated so that the two rectangular grooves are adjacent. If the circular plate is to be calibrated and positioned, the two clamping members 41 are rotated so that the two arc grooves are adjacent. Circular holes are provided at both ends of the top of the two clamping members 41, and the inside of the two circular holes are movably penetrated by plugging columns 45. One end of the two plugging columns 45 is movably inserted into the inside of the two plug holes, so that the rotated clamping members 41 can be fixed, and the two A limiting hole is provided on one side of each limiting plate 42, and a limiting bearing 6 for limiting the two driving members 46 is installed inside the two limiting holes. The outer bearing ring of the limiting bearing 6 is fixedly connected to the inner side wall of the limiting hole, and the inner bearing ring of the limiting bearing 6 is fixedly sleeved on the outer surface of one end of the driving member 46, so that the two driving members 46 can only rotate. One end of the two driving members 46 is respectively threadedly inserted into the interior of the two movable blocks 43. When the two driving members 46 are rotated, the two driving members 46 apply a spiral thrust to the two movable blocks 43, so that the two movable blocks 43 drive the two clamping members 41 to approach each other, so that the plate on the pad 3 can be clamped and corrected.
[0018] Reference Figure 4The driving member 46 is composed of a rotating member 461 and a threaded rod 462. One end of the rotating member 461 is welded to one end of the threaded rod 462. The threaded rod 462 is threadedly inserted into the interior of the movable block 43. The rotating member 461 can be used to rotate the threaded rod 462. The thread self-locking condition of the threaded rod 462 depends on the spiral angle, friction coefficient and load of the thread. The thread self-locking condition can be calculated by the following formula: Self-locking condition = friction coefficient × tan (spiral angle) ≥ 1. When this condition is met, the threaded connection is self-locking. The above contents are all existing technologies, and in actual applications, the corresponding self-locking angle can be set according to the friction coefficient of the material. I will not go into details here.
[0019] The above describes an exemplary implementation of the calibration mechanism of a plotter provided by the present disclosure with reference to a preferred embodiment. However, it will be understood by those skilled in the art that, without departing from the concept of the present disclosure, various variations and modifications may be made to the above-mentioned specific embodiments, and various combinations of the various technical features and structures proposed in the present disclosure may be made without exceeding the scope of protection of the present disclosure, which is determined by the appended claims.
