[0023] See also Figure 1-5 The utility model provides the following technical solutions: a processing table of an automatic drilling and tapping device, comprising a base 1, a processing table 2 is fixed on the base 1, a clamping mechanism 3 is arranged in the processing table 2, a guiding mechanism 4 is arranged between the clamping mechanism 3 and the processing table 2, a driving mechanism 5 is arranged between the inside of the processing table 2 and the clamping mechanism 3, the clamping mechanism 3 comprises a first slide 31 and a second slide 32 symmetrically distributed at both ends of the processing table 2 and a clamping plate 33 arranged inside the first slide 31 and the second slide 32 through a cylinder, an upper connecting group 6 is arranged between the bottom of the first slide 31 and the driving mechanism 5, and a lower connecting group 7 is arranged between the bottom of the second slide 32 and the driving mechanism 5; the guiding mechanism 4 comprises a fixed A No. 1 guide column 41 fixed at the front and rear ends of the No. 1 slide 31 and a No. 2 guide column 42 fixed at the front and rear ends of the No. 2 slide 32, as well as an upper guide rail 43 and a lower guide rail 44 fixed on the front and rear end surfaces of the inner side of the processing table 2; the driving mechanism 5 includes two No. 1 screw rods 51 that rotate symmetrically at the front and rear ends of the inner side of the processing table 2 and a No. 1 internally threaded slider 52 that is threadedly connected to the outer end of the No. 1 screw rod 51, as well as a No. 2 screw rod 53 that rotates in the middle of the interior of the processing table 2 and a No. 2 internally threaded slider 54 that is threadedly connected to the outside of the No. 2 screw rod 53, and also includes a synchronous wheel 55 fixed at the same end of the two No. 1 screw rods 51 and a No. 1 internally threaded slider 52 and a synchronous belt 56 connected to the three synchronous wheels 55.

[0024] Specifically, guide column No. 1 41 and guide column No. 2 42 are distributed in parallel up and down, the upper guide rail 43 and the lower guide rail 44 are symmetrically arranged up and down, guide column No. 1 41 slides in the upper guide rail 43, and guide column No. 2 42 slides in the lower guide rail 44. The middle part of the upper guide rail 43 bulges upward, and the middle part of the lower guide rail 44 is recessed downward. In this embodiment, the guide mechanism 4 limits the paths of slide No. 1 31 and slide No. 2 32 so that they are at the same height when separated, and are in an upper and lower separated state when meeting, and do not affect each other.

[0025] Specifically, the driving mechanism 5 also includes a servo motor 57 fixed to the side end of the processing table 2 and the output end is fixed to the end of one of the synchronous wheels 55. The threads in the No. 1 screw 51, the No. 1 internal thread slider 52 and the No. 2 screw 53, the No. 2 internal thread slider 54 are arranged in different directions. In this embodiment, the driving mechanism 5 realizes the linkage between the No. 1 slide 31 and the No. 2 slide 32, so that they move in different directions synchronously to achieve the purpose of station switching.

[0026] Specifically, the upper connection group 6 includes a telescopic seat 61 fixed to the upper end of the No. 1 internal thread slider 52, a telescopic rod 62 sliding in the telescopic seat 61, and a rotating rod 63 fixed to one side of the telescopic rod 62. The other end of the rotating rod 63 is also rotatably connected to the front and rear end center axis position of the No. 1 slide 31. In this embodiment, the upper connection group 6 can adapt to the height difference of the upper guide rail 43 protruding upward while connecting the driving mechanism 5 and the No. 1 slide 31, thereby ensuring the switching of the No. 1 slide 31 between the two stations.

[0027] Specifically, the lower connection group 7 includes a slide 71 fixed at the front and rear ends of the No. 2 internal threaded slider 54 and a follower slider 72 sliding in the slide 71, and a connecting rod 73 rotating at the upper end of the follower slider 72. The upper end of the connecting rod 73 is also rotatably connected to the bottom of the No. 2 slide 32. In this embodiment, the lower connection group 7 can adapt to the height difference of the downward depression in the middle of the lower guide rail 44 while connecting the drive mechanism 5 and the No. 2 slide 32, thereby ensuring the switching of the No. 2 slide 32 between the two workstations.

[0028] The working principle and use process of the utility model are as follows: the workpiece to be processed is placed on the No. 1 slide 31, and the cylinder inside it pushes the clamping plate 33 to clamp the workpiece. The drilling station is processed first. After the drilling station is processed, the servo motor 57 is started, and the servo motor 57 drives the three synchronous wheels 55 to rotate synchronously through the synchronous belt 56. The synchronous wheel 55 drives the No. 1 internal thread slider 52 and the No. 2 screw rod 53 to rotate synchronously. The No. 1 internal thread slider 52 moves through the spiral movement with the No. 1 screw rod 51, and the No. 2 internal thread slider 54 moves through the spiral movement with the No. 2 screw rod 53. Since the No. 1 screw rod 51, the No. 1 internal thread slider 52 and the No. 2 screw rod 53 and the No. 2 internal thread slider 54 are set in opposite directions, the No. 1 internal thread slider 52 and the No. 2 internal thread slider 54 move synchronously in different directions, and the No. 1 guide column 41 follows and slides in the upper guide rail 43, and the No. 2 guide column 41 follows and slides in the upper guide rail 43. The guide column 42 follows and slides in the lower guide rail 44. When the No. 1 guide column 41 slides to the protruding position in the middle of the upper guide rail 43, the telescopic rod 62 will extend upward from the inside of the telescopic seat 61, and the No. 1 slide 31 follows and rotates in the rotating rod 63, and it will only rotate at the slope position. When the No. 2 guide column 42 moves to the recessed position in the middle of the lower guide rail 44, the connecting rod 73 will change its angle, and the follow-up slider 72 will slide in the slide seat 71; the No. 1 slide 31 passes through the protruding position of the upper guide rail 43 and then resets to the original height, and the No. 2 slide 32 passes through the recessed position of the lower guide rail 44 and then resets to the original height. At this time, the workpiece with the hole drilled on the No. 1 slide 31 is moved to the tapping station, and the workpiece to be processed is placed on the No. 2 slide 32. The No. 2 slide 32 is located at the drilling station, and switches back and forth in sequence, so that the workpiece can be drilled and tapped on the same slide.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
