[0018] 4. The top shaft unit applies continuous pressure to the linkage shaft through the spring and the top roller to offset the axial force during the transmission of the bevel gear and prevent the linkage shaft from moving; a hydraulic-driven top roller can be optionally configured to further improve the structural rigidity during complex-angle drilling and ensure the stability of long-term processing.

[0019] 5. The electric sliding rails of the limit components can move within a large range along the fixed slots, compatible with heat insulation cover molds of various sizes; the top wheels of the flipping arm adopt a rolling contact design, which can not only provide sufficient clamping force but also avoid damaging the surface of the mold, and is suitable for mold processing with different materials and accuracy requirements.

The transmission gear 37 is engaged with the other connecting gear 28. The top shaft unit 38 is fixedly arranged on the upper wall of the second mounting seat 25 and is located below the other end of the linkage shaft 32; driven by the extension of the electric push rod 34, the sleeve 33 is moved on the linkage shaft 32 by means of the toggle rod 35, so that the bevel gear 36 on the sleeve 33 is engaged with the bevel gear 36 on the double universal shaft coupling 26.

The top wheel 47 is movably arranged on the other end of the reversing arm 46; the electric slide rail 41 drives the bearing seat 42 to move, so as to promote the reversing arm 46 to move along the fixing groove 16 for clamping. By means of the second hydraulic cylinder 44 driving the rack 45 to move, the reversing arm 46 is promoted to turn over by means of the reversing gear 43, so that the reversing arm 46 can be inclined and located below the base 11, which is suitable for limiting molds of different shapes and turning up or turning over one end of the mold from the lower wall of the mold, and fits the hole positions with different wall surfaces and orientations for processing.

[0034] Specifically, the electric slide rail 41 drives the bearing seat 42 to move through a lead screw. The concave design of the bearing seat 42 facilitates the accommodation of the rack 45 and the turning gear 43 to achieve a compact layout. The turning gear 43 rotates under the action of the force of the rack 45 to drive the turning arm 46 to rotate. The second hydraulic cylinder 44 drives the linear movement of the rack 45. The turning arm 46 is used to install the top wheel 47 and apply a clamping force and an upward top force. The top wheel 47 can roll, which facilitates the upward top from the bottom of the mold to cause the workpiece to turn over.

[0035] As a preferred solution, furthermore, the limiting components 4 are driven separately, and the limiting components 4 clamp through the relative movement of the turning arm 46 and are used for fixing the mold during use.

[0036] As a preferred solution, furthermore, the turning arm 46 can be located below the base 11 and is used for storing or turning over the mold.

[0037] As a preferred solution, furthermore, both ends of the double-headed universal shaft coupling 26 can be relatively turned over, which is used for designing linkage requirements to achieve multi-directional and multi-angle drilling operations.

[0038] Working principle: S1. Place the equipment stably through the base 11 in the main body structure 1. After the equipment is powered on, the workpiece (heat shield mold) can be placed in the middle of the upper wall of the base 11. Then, according to its size and shape, drive the electric slide rail 41 in the limiting component 4 respectively. The electric slide rail 41 drives the bearing seat 42 to move, and the turning arm 46 can be moved along the fixed groove 16 to clamp the workpiece. And by driving the second hydraulic cylinder 44 to drive the rack 45 to move, the rotation of the turning gear 43 is realized, and then the turning arm 46 can be driven to turn over. The turning arm 46 can be moved and clamped relative to the base 11 vertically, or the turning arm 46 can be tilted to clamp and press down the workpiece for limiting. The two turning arms 46 on one side of the workpiece can also be vertically blocked, and the two turning arms 46 on the other side are turned over below the base 11. Then, the turning arm 46 is moved under the workpiece. With the turning of the turning arm 46 and the rotation of the top wheel 47 after contacting the workpiece, the workpiece is lifted on one side to achieve side turning. S2. After the workpiece is fixed, the equipment can be controlled by the controller 13 on the gantry 12. According to the hole positions of the mold, drive the cross-shaped slide rail 14 to drive the front-back and left-right movement of the drilling component 2, and drive the first hydraulic cylinder 15 to drive the drilling component 2 to lift and lower, so as to adjust the hole depth and the lifting of the drill rod 27 to contact the workpiece. S3. During the drilling operation, by driving the motor 22 on the base 21, the double-headed universal shaft coupling 26 can be driven 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 operation. S4. The direction of the drill rod 27 can be controlled by driving the electric push rod 34 in the reversing assembly 3. The extension of the electric push rod 34 drives the sleeve 33 to translate on the linkage shaft 32 with the help of the toggle rod 35, so that the bevel gear 36 on the sleeve 33 engages with the bevel gear 36 on the double-headed universal shaft connector 26, and then by controlling the forward or reverse rotation of the motor 22, the linkage shaft 32 is driven to rotate on the shaft frame 31, and the rotation of the transmission gear 37 engages with one of the docking gears to drive the docking gear on the second mounting seat 25 to rotate. Since the second mounting seat 25 is connected to the first The mounting seats 23 are limited by the connecting arm 24 and the fixed arrangement of the docking gear on the first mounting seat 23, so that the docking gear on the second mounting seat 25 will move along the docking gear on the first mounting seat 23 when it rotates, thereby driving the first mounting seat 23 to flip relative to the second mounting seat 25, and at the same time driving the two ends of the double-headed universal shaft connector 26 to flip relative to each other. The orientation of the drill rod 27 is changed by changing the orientation of the drill rod 27 and driving it to move with the cross-shaped slide rail 14, which is suitable for hole processing on different wall surfaces and can realize the hole expansion work after drilling; S5. After adjusting the direction of the drill rod 27, the bevel gears 36 need to be relatively separated, and the linkage shaft 32 will be limited by the top shaft unit 38 to prevent the transmission gear 37 from rotating, thereby ensuring the stability of the first mounting seat 23 and the second mounting seat 25 after flipping; that is, with the help of the force of the spring 383, the top seat 382 is at the top of the slide bar 381, so that the top roller 384 on the top seat 382 is pressed against the lower wall of the linkage shaft 32, and a vertical lateral force is applied to the axial direction of the linkage shaft 32. Since the top roller 384 can rotate, when the bevel gears 36 are relatively engaged for transmission, the rotation of the linkage shaft 32 will drive the top roller 384 to rotate, and the top roller 384 is forced to descend on the slide bar 381 with the help of the top seat 382, or the top seat 382 is controlled by a hydraulic cylinder to lift the top roller 384 to apply force to the linkage shaft 32.
