Therefore, in the process of placing the workpiece on the positioning plate 11, the front end of the workpiece will abut against the fixed positioning block located at the front end of the positioning plate 11, so as to determine the longitudinal position of the workpiece, and meanwhile, the fixed positioning blocks 13 and the sliding positioning blocks 14 located at the two sides of the positioning plate can limit the workpiece to be placed between the fixed positioning block and the sliding positioning block, so as to determine the transverse position of the workpiece. Moreover, when the width specification of the workpiece changes, the positioning slide block can be pushed to move by screwing the screw rod, so that the distance between the slide block 142 and the fixed positioning block 13 can be adjusted, and the positioning of workpieces with different sizes can be adapted. In detail, the positioning slide 141 is provided with a slide slot 1411, and the bottom of the slide block 142 is provided with a slide portion adapted to the slide slot 1411.

In terms of fixing the workpiece, the pressing mechanism 12 includes a pressing head 121 for contacting the workpiece, a telescopic mechanism 122 for driving the pressing head to press down, and a frame 123 for mounting the telescopic mechanism, wherein the pressing head 121 is connected to the telescopic mechanism 122. The telescopic mechanism 122 may be a hydraulic telescopic mechanism or a pneumatic telescopic mechanism, preferably, the telescopic mechanism 122 is a pneumatic telescopic rod mechanism, and the pressure head 121 is connected to a telescopic rod of the pneumatic telescopic rod mechanism.

The inductive switch 3 comprises a contact switch 31 and a connecting seat 32 for adjusting the position of the contact switch 31, and the connecting seat 32 is provided with a screw rod body 33 for connecting and installing the contact switch. When the front end of the workpiece contacts the fixed positioning block 13 located at the front end of the positioning plate, the contact switch is triggered together to sequentially control the pressing head 121 to press down and the drill to extend out for drilling. Because the shape of the workpiece is variable, it cannot be guaranteed that the trigger point of the contact switch 31 and the positioning point of the fixed positioning block located at the front end of the positioning plate 11 are located on the same vertical plane, and therefore, the position of the contact switch can be adjusted by the arrangement of the screw rod body 33, so as to meet the adjustment requirement in the actual processing process.
