[0002] Hardware processing is the basis of modern manufacturing, and its processing precision and efficiency directly affect the product quality in downstream equipment manufacturing, automobile parts, smart home and other fields. As a key processing equipment integrating drilling and tapping functions, drilling and tapping integrated machine has been widely used in batch production of hardware parts. In actual production, hardware parts often need to be processed on multiple surfaces, involving the processing of through holes, blind holes and threaded holes in different directions, which puts high requirements on the positioning accuracy, turnover stability and processing continuity of the parts.

[0003] To this end, the present application designs a hardware drilling and tapping integrated machine with a turnover positioning structure. The existing hardware drilling and tapping processing method mainly relies on fixed clamps. For parts with high surface precision requirements and multi-directional drilling and tapping, there is a risk of unstable positioning accuracy and surface scratches caused by excessive clamping or turnover deviation. It is also necessary to manually adjust the size of the clamp or disassemble and assemble the workpiece repeatedly, which improves the clamping and positioning efficiency, but also causes hole position deviation, insufficient thread precision, poor processing consistency and subsequent assembly difficulties.

[0045] In specific implementation:

[0046] Firstly, the feeding component 2 in the present application is used for position adjustment of the transverse or longitudinal movement of the workbench 3, so as to move the workpiece to the working area below the drilling and tapping component 4, and the drilling and tapping component 4 is used for controlling the downward movement of the drill bit and tap, thereby realizing the effects of drilling and tapping threads on the workpiece respectively.

[0047] In the initial clamping stage of the workpiece, the workpiece needing multi-directional drilling and tapping is placed on the upper end of the semi-spherical base 6. It should be noted that the upper end surface of the semi-spherical base 6 is initially flush with the upper end surface of the semi-cylinder 5, and the plurality of inner support plates 72 are initially away from each other under the action of the tension spring, and the plurality of clamping plates 52 are close to each other under the action of the compression spring. During the placement of the workpiece on the upper end of the semi-spherical base 6, the upper ends of the plurality of inner support plates 72 are extruded by the workpiece and will slide along the cross rod 71 and approach each other, and the plurality of clamping plates 52 are extruded by the workpiece and will slide along the corresponding upper and lower limit rods 51 and move away from each other, until the lower end surface of the workpiece is tightly attached to the upper end surface of the semi-spherical base 6. At this time, the inner walls of the plurality of clamping plates 52 are attached to the outer wall of the workpiece, and the outer walls of the plurality of inner support plates 72 are attached to the inner wall of the workpiece, thereby realizing the effects of internal support and external clamping of the workpiece by the plurality of inner support plates 72 and the plurality of clamping plates 52, and avoiding the problem that the position of the workpiece is deviated after placement and affects the subsequent clamping work.

[0048] When the outer walls of the plurality of inner support plates 72 are attached to the inner wall of the workpiece, the upper end surface of the semi-spherical base 6 is initially flush with the upper end surface of the semi-cylinder 5. It should be noted that since the driving gear 832 is always engaged with the tooth ring 82, the semi-spherical base 6 cannot be rotated by external force, but can only be driven by the driving gear 832 to rotate the semi-spherical base 6. In addition, under the action of the compression spring, the upper and lower abutment columns 761 and 763 are in close abutment state, at this time, the plurality of strong magnetic wedge-shaped sliders on the upper and lower abutment columns 761 and 763 are magnetically attracted and connected to each other, and since the upper abutment column 761 is kept synchronous rotation with the lead screw 751 and the lower abutment column 763 is kept synchronous rotation with the transmission shaft 762 under the action of the cooperating slider, the effects of synchronous rotation of the lead screw 751 and the transmission shaft 762 are realized.

[0049] Then the external motor control drives the transmission shaft 762 to rotate, the transmission shaft 762 drives the upper butt joint column 761 to rotate through the lower butt joint column 763, the upper butt joint column 761 drives the lead screw 751 to rotate synchronously, under the limiting action of the limiting sliding groove and the limiting sliding block, the lead screw 751 drives the abutting column 752 to slide upwards through the threaded transmission, until the outer wall of the abutting column 752 simultaneously abuts against the inner walls of the plurality of inner supporting plates 72, so that it is tightly attached to the inner wall of the workpiece, thereby realizing the further strengthening of the inner supporting force of the plurality of inner supporting plates 72 by the abutting column 752, so that the plurality of inner supporting plates 72 collectively fasten and internally clamp the inner wall of the workpiece, and the abutting column 752 and the lead screw 751 cooperate to always maintain the internal clamping effect of the plurality of inner supporting plates 72 on the inner wall of the workpiece, avoiding the problems of traditional fixed clamps, such as surface scratching of the workpiece due to clamping too tightly, and positional deviation of the workpiece caused by unstable positioning and clamping, directly affecting the drilling and threading effect.

[0050] In the drilling stage of the workpiece, after the plurality of inner supporting plates 72 collectively fasten and internally clamp the inner wall of the workpiece, first control the feed component 2 to drive the workbench 3 to move horizontally or vertically to adjust the position until the workbench 3 moves the workpiece to the lower side of the drilling and threading component 4 through the semi-cylindrical body 5 and the semi-spherical base 6, and the position of the horizontal end face of the workpiece that needs to be drilled is located directly below the drill bit of the drilling and threading component 4, then control the drill bit feed to control the drill bit to move downward and drill the workpiece, when the hole position is drilled, first control the electromagnet 765 to start working, under the magnetic attraction of the electromagnet 765, the lower butt joint column 763 moves downward and magnetically connects to the electromagnet 765, during which the lower butt joint column 763 drives the annular plate 764 to move downward synchronously, and the upper butt joint column 761 is disconnected from the magnetic attraction and clamping connection with the lower butt joint column 763, then the external motor controls the connecting shaft to drive the driving gear 832 to rotate intermittently, the driving gear 832 drives the gear ring 82 to rotate, and the semi-spherical base 6 rotates synchronously, at this time the cross rod 71, the plurality of inner supporting plates 72, the lead screw 751 and the abutting column 752 all rotate synchronously with the semi-spherical base 6, thereby realizing the effect of driving the workpiece to rotate intermittently around the lead screw 751 to adjust the drilling hole position, during which the drill bit feed repeatedly drills multiple hole positions, until the plurality of hole positions on the horizontal end face of the workpiece are drilled.

[0051] The tapping stage of the workpiece is performed. After the holes in the multiple positions of the horizontal end surface of the workpiece are drilled, the position adjustment of the feeding component 2 driving the workbench 3 to move horizontally or vertically is controlled again until the workbench 3 drives the workpiece to move to the lower side of the tapping component 4 through the semi-cylindrical body 5 and the semi-spherical base 6, and the hole in the horizontal end surface of the workpiece is located directly below the tap of the tapping component 4. Then, the tap feeding component is controlled to move downward and tap the corresponding hole. When the tapping of the hole is completed, the above-mentioned step of adjusting the angle of the workpiece is repeated, and the tap feeding component is controlled to repeatedly tap the multiple holes during the adjustment. When the tapping of the holes in the horizontal end surface of the workpiece is completed, the workpiece is flipped.

[0052] The flipping stage of the workpiece is performed. After the drilling and tapping of the horizontal end surface of the workpiece are completed, any rotating shaft is rotated by an external motor. The rotating shaft drives the other rotating shaft to rotate synchronously through the transmission belt. The left and right rotating shafts drive the corresponding front and rear transmission gears 831 to rotate synchronously. The multiple transmission gears 831 drive the semi-cylindrical body 5 to rotate around the support rod 53 through the corresponding arc-shaped rack 81. The semi-cylindrical body 5 drives the multiple inner supporting plates 72 to rotate synchronously through the semi-spherical base 6. The multiple inner supporting plates 72 and the semi-spherical base 6 drive the workpiece to rotate 90 degrees around the support rod 53, thereby achieving the effect of flipping the workpiece. The size of the clamp is adjusted manually, and the workpiece is loaded and unloaded. The efficiency of clamping and positioning is improved, and the problems of hole position deviation, insufficient thread precision, poor processing consistency, and difficult subsequent assembly are avoided. It should be noted that when the workpiece rotates 90 degrees around the support rod 53, the electromagnet 765 stops working. Under the action of the compression spring, the annular plate 764 drives the lower butt joint column 763 to slide upward along the transmission shaft 762, so that the upper end of the lower butt joint column 763 is movably attached to the outer wall of the semi-spherical base 6. After the semi-spherical base 6 is reset, the magnetic attraction and clamping connection between the upper butt joint column 761 and the semi-spherical base 6 are restored.

[0053] In the taking-out stage, the reverse rotation of any one rotating shaft is also controlled by the external motor, and the left and right rotating shafts will drive the corresponding front and rear transmission gears 831 to rotate reversely synchronously, and the plurality of transmission gears 831 will drive the semicylinder 5 to rotate reversely around the supporting rod 53 through the corresponding arc-shaped rack 81, and the semicylinder 5 will drive the plurality of inner supporting plates 72 to rotate reversely synchronously through the hemispherical base 6, until the plurality of inner supporting plates 72 and the hemispherical base 6 jointly drive the workpiece to rotate reversely around the supporting rod 53 by 90 degrees to restore the original position, during which the upper butt joint column 761 will be close to the annular plate 764 and restore the magnetic attraction connection and the clamping connection under the action of the compression spring, and finally the reverse rotation of the transmission shaft 762 is controlled by the external motor, and the transmission shaft 762 will drive the upper butt joint column 761 to rotate reversely through the lower butt joint column 763, and the upper butt joint column 761 will drive the lead screw 751 to rotate reversely synchronously, and under the limiting action of the limiting sliding groove and the limiting sliding block, the lead screw 751 will drive the abutting column 752 to slide downward to restore the original position through the threaded transmission, at this time, the plurality of inner supporting plates 72 will only rely on the action of the stretching spring to adhere to the outer wall of the workpiece after losing the abutting force of the abutting column 752, so as to realize the effect of freely taking out the workpiece by the staff, without the staff to disassemble the clamp and other laborious steps, saving time and effort.

[0054] In summary, the present application has the following advantages:

[0055] Advantage one, in the initial clamping of the workpiece stage, the staff places the workpiece needing multi-directional drilling and tapping on the upper end of the hemispherical base 6, and after being extruded by the workpiece, the plurality of clamping plates 52 will slide along the corresponding upper and lower limiting rods 51 and move away from each other, until the lower end face of the workpiece is tightly adhered to the upper end face of the hemispherical base 6, at this time, the inner walls of the plurality of clamping plates 52 are adhered to the outer wall of the workpiece, and the outer walls of the plurality of inner supporting plates 72 are adhered to the inner wall of the workpiece, so as to realize the effect that the plurality of inner supporting plates 72 and the plurality of clamping plates 52 cooperate to jointly support the inside and clamp the outside of the workpiece, avoiding the problem that the position of the workpiece is deviated after being placed, affecting the subsequent clamping work.

[0056] Advantage two, under the action of the compression spring, the upper butt joint column 761 and the lower butt joint column 763 are in close butt joint state, at this time, the plurality of strong magnetic wedge-shaped sliding blocks on the upper butt joint column 761 and the lower butt joint column 763 are magnetically attracted and clamped, and because the upper butt joint column 761 will keep synchronous rotation with the lead screw 751 under the action of the cooperating sliding block, and the lower butt joint column 763 will keep synchronous rotation with the transmission shaft 762, so as to realize the effect of synchronous rotation of the lead screw 751 and the transmission shaft 762.

[0057] Advantage three, then the peripheral motor control transmission shaft 762 rotates, the transmission shaft 762 will drive the upper butt joint column 761 to rotate through the lower butt joint column 763, the lead screw 751 will drive the abutting column 752 to slide upwards through the threaded transmission, until the abutting column 752 outer wall will simultaneously abut the inner wall of the plurality of inner support plates 72, so that it is tightly attached to the inner wall of the workpiece, thereby realizing the further strengthening of the inner supporting force of the plurality of inner support plates 72 through the abutting column 752, so that the plurality of inner support plates 72 collectively fasten and internally clamp the inner wall of the workpiece, and the abutting column 752 and the lead screw 751 cooperate to always maintain the internal clamping effect of the plurality of inner support plates 72 on the inner wall of the workpiece, avoiding the problems of traditional fixed clamps, such as surface precision requirements, multi-directional drilling and tapping of workpieces, surface scratches caused by excessive clamping, and unstable positioning and clamping leading to workpiece position deviation directly affecting drilling and tapping effects.

[0058] Advantage four, during the drilling stage of the workpiece, the electromagnet 765 is controlled to start working, the lower butt joint column 763 will move downward and be magnetically connected to the electromagnet 765, during which the lower butt joint column 763 will drive the annular plate 764 to move downward synchronously, and the upper butt joint column 761 will be disconnected from the magnetic connection and clamping connection with the lower butt joint column 763, then the peripheral motor controls the connecting shaft to drive the driving gear 832 to rotate intermittently, driving the hemispherical base 6 to rotate synchronously intermittently, thereby achieving the effect of driving the workpiece to rotate intermittently around the lead screw 751 to adjust the drilling hole position.

[0059] Advantage five, during the workpiece flipping stage, first control any one of the rotating shafts to rotate by the peripheral motor, the left and right two rotating shafts will drive the corresponding front and rear two transmission gears 831 to rotate synchronously, and continue to drive the semicircular cylinder 5 to rotate around the support rod 53, until the plurality of inner support plates 72 and the hemispherical base 6 collectively drive the workpiece to rotate 90 degrees around the support rod 53, thereby achieving the effect of driving the workpiece to flip, without the need for manual repeated adjustment of the size of the clamp or disassembly and assembly of the workpiece, effectively improving the clamping and positioning efficiency, and also avoiding problems such as hole position deviation, insufficient thread precision, poor processing consistency, and difficult subsequent assembly.

[0060] The sixth advantage is that in the taking-out stage, the external motor controls the reverse rotation of any one rotating shaft, and the left and right rotating shafts will drive the corresponding front and rear transmission gears 831 to rotate reversely synchronously until the plurality of inner supporting plates 72 and the hemispherical base 6 drive the workpiece to rotate reversely by 90 degrees around the supporting rod 53 to restore to the original position. During this period, the upper butt joint column 761 will be close to the annular plate 764 and restore the magnetic attraction connection and the clamping connection. Finally, the external motor controls the reverse rotation of the transmission shaft 762, and the lead screw 751 will drive the abutting column 752 to slide downward to restore to the original position through threaded transmission. At this time, the plurality of inner supporting plates 72 will only rely on the action of the tension spring to adhere to the outer wall of the workpiece after losing the abutting force of the abutting column 752, thereby realizing the effect of freely taking out the workpiece by the worker, without the laborious steps such as disassembling and assembling the clamp, saving time and effort.
