[0050] Working principle:

[0051] S1. The equipment is placed stably on the base 11 in the main body structure 1, and after the equipment is powered on, the workpiece (heat shield mold) is placed on the upper wall of the base 11; then according to the size and shape, the electric slide rails 41 in the limiting assemblies 4 are driven respectively, the bearing seats 42 are driven to move by the electric slide rails 41, the turnover arms 46 are moved along the fixed grooves 16 to clamp the workpiece, the rack 45 is driven to move by the second hydraulic cylinder 44, the turnover gear 43 is driven to rotate, and the turnover arm 46 can be turned over, the turnover arm 46 can be moved perpendicularly to the base 11 for clamping, or the turnover arm 46 can be inclined for clamping and pressing the workpiece; the two turnover arms 46 on one side of the workpiece can be vertically shielded, the two turnover arms 46 on the other side are turned over to below the base 11, then the turnover arms 46 are moved to below the workpiece, the workpiece is turned over by the rotation of the turnover arms 46 and the top wheel 47 after contacting the workpiece.

[0052] S2. When the workpiece is fixed, the controller 13 on the gantry 12 is used to control the equipment, the cross-shaped slide rail 14 is driven to move the drilling assembly 2 forward and backward and left and right, and the first hydraulic cylinder 15 is driven to drive the drilling assembly 2 to ascend and descend, so as to adjust the hole depth and the lifting of the drill rod 27 to contact the workpiece;

[0053] S3. In the drilling process, the motor 22 on the base 21 is driven to drive the double-head universal shaft connector 26 to rotate under the limiting action of the first mounting seat 23 and the second mounting seat 25, and then the drill rod 27 is driven to rotate for drilling.

[0054] S4. The orientation of the drill rod 27 can be achieved by driving the electric push rod 34 in the drive reversing assembly 3, the extension of the electric push rod 34 drives the sleeve 33 to translate on the connecting shaft 32 by means of the toggle lever 35, which makes the bevel gear 36 on the sleeve 33 engage with the bevel gear 36 on the double-end universal shaft connector 26, and then by controlling the forward rotation or reverse rotation of the motor 22, the connecting shaft 32 is driven to rotate on the shaft support 31, and by means of the rotation of the transmission gear 37 engaging with one of the mating gears, the mating gear on the second mounting seat 25 is driven to rotate. Since the second mounting seat 25 is limited by the connecting arm 24 between the first mounting seat 23 and the second mounting seat 25, and the mating gear on the first mounting seat 23 is fixedly arranged, the rotation of the mating gear on the second mounting seat 25 will make it walk along the mating gear on the first mounting seat 23, thereby realizing the overturning of the first mounting seat 23 relative to the second mounting seat 25, and the relative overturning of the two ends of the double-end universal shaft connector 26. The orientation of the drill rod 27 is achieved by changing the orientation of the drill rod 27 and the cooperation of the cross-shaped slide rail 14 driving it to move, which is suitable for hole processing of different wall surfaces, and can realize reaming after drilling.

[0055] S5. After adjusting the orientation of the drill rod 27, the bevel gear 36 needs to be relatively separated, and the connecting shaft 32 will be limited by the jack unit 38 to prevent the transmission gear 37 from rotating, ensuring the stability of the first mounting seat 23 and the second mounting seat 25 after overturning. That is, by means of the force of the spring 383, the top seat 382 is at the top of the slide rod 381, which makes the top roller 384 on the top seat 382 fit the lower wall of the connecting shaft 32, and exerts a vertical transverse force on the axial direction of the connecting shaft 32. Since the top roller 384 can rotate, when the bevel gear 36 engages in transmission, the rotation of the connecting shaft 32 will drive the rotation of the top roller 384, and the force of the top roller 384 will make the top seat 382 descend on the slide rod 381, or the lifting of the top roller 384 by the force of the top seat 382 can be controlled by the hydraulic cylinder to exert force on the connecting shaft 32.

[0056] Finally, it should be pointed out that the above embodiments are only used to illustrate the technical solutions of the present application and not to limit it. Other modifications or functional replacements of the technical solutions of the present application made by those skilled in the art should be covered within the scope of the claims of the present application as long as they do not deviate from the spirit and scope of the technical solutions of the present application.
