DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] Embodiment I: A dual-spindle CNC drilling and tapping machine, such as Figure 1-Figure 5 As shown, it includes a hollow base 1, a shell 2, a storage frame 3, a mounting ring 41, a servo motor I4, an electric clamp 5 and a rodless cylinder 6. The interior of the hollow base 1 is a hollow structure, and a square notch is provided at the left rear side thereof, and the inner bottom thereof is set as an inclined surface inclined toward the square notch, and the debris generated by drilling and tapping will slide out of the square notch along the inclined surface. The shell 2 is fixedly installed on the top of the hollow base 1 by bolts, and the drilling and tapping of the workpiece is completed in the shell 2. The storage frame 3 is rotatably arranged between the left and right inner walls of the shell 2, and a mounting ring 41 is fixedly arranged on the right side wall of the shell 2. The servo motor I4 is installed on the mounting ring 41, and the output shaft of the servo motor I4 is fixedly connected to the right end of the storage frame 3. The servo motor I4 can drive the storage frame 3 to rotate. An electric clamp 5 is arranged in the middle of the storage frame 3, and the workpiece to be processed can be placed on the electric clamp 5 for clamping and fixing.

[0031] like Figure 6As shown, it also includes a rodless cylinder 6 and a drilling mechanism, the drilling mechanism includes a mounting ring 7, a gear box 71, a gear ring 72, a double-axis drilling rig 73, a servo motor II 74 and a guide rail 75. The rodless cylinder 6 is fixedly installed on the top of the housing 2, and a mounting ring 7 is slidably arranged on it. The storage frame 3 is located in the closed annular space surrounded by the mounting ring 7, and guide rails 75 are arranged at the lower part of the left and right inner walls of the housing 2. Under the cooperation of the rodless cylinder 6 and the guide rail 75, the mounting ring 7 can be driven to move closer to or away from the electric clamp 5. The mounting ring 7 is provided with a gear. Box 71, the gear box 71 is set to a ring shape that is compatible with the mounting ring 7, and can be driven by a servo motor II 74. The ring gear 72 is connected to the gear box 71 through a gear transmission. Under the joint action of the servo motor II 74 and the gear box 71, the ring gear 72 can be driven to rotate, and a double-axis drilling rig 73 is installed on the ring gear 72. The drill bit of the double-axis drilling rig 73 is initially vertically downward. When the ring gear 72 rotates, it can drive the double-axis drilling rig 73 to rotate synchronously, and in the extreme state, the drill bit of the double-axis drilling rig 73 can be horizontally facing forward or horizontally facing backward.

[0032] The workpiece is placed on the electric clamp 5, which is clamped and fixed by the electric clamp 5, and then the rodless cylinder 6 is started. Under the guidance of the guide rail 75, the mounting ring 7 is driven to approach the electric clamp 5, so that the drill bit of the double-axis drill 73 is aligned with the workpiece, and the double-axis drill 73 completes the drilling and tapping of the workpiece. If the workpiece needs to be drilled on multiple sides, the servo motor I4 can be started to drive the storage frame 3 to rotate, and the surface of the workpiece to be drilled can be aligned with the drill bit of the double-axis drill 73. At the same time, the servo motor I4 can be used in conjunction with the gear box 71 to drive the gear ring 72 to rotate, and drive the double-axis drill 73 to rotate synchronously to change the angle of the drill bit of the double-axis drill 73, so as to adjust the drilling and tapping position of the workpiece without removing the workpiece and re-clamping it. Moreover, the debris generated by drilling and tapping can be discharged through the square hole on the rear side of the hollow base 1.

[0033] Example II: Figure 2 and Figure 5 As shown, a direction adjustment component 8 is provided at the bottom of the storage frame 3, and the direction adjustment component 8 includes a bearing bracket 81, a slot plate 82, an electric push rod 83 and a drive shaft 84. The electric clamp 5 can be connected to the storage frame 3 in a hinged manner. The bearing bracket 81 is fixedly arranged at the bottom of the storage frame 3, and its position corresponds to the electric clamp 5. A slope that forms an angle of 45° with the storage frame 3 is provided on the bearing part of the bearing bracket 81. The electric push rod 83 is fixedly arranged on the slope, and the movable end of the electric push rod 83 faces left, and the drive shaft 84 is fixedly arranged on its movable end. Two slot plates 82 are symmetrically fixedly arranged at the bottom of the electric clamp 5, and waist-shaped holes are opened on the two slot plates 82, and the drive shaft 84 is simultaneously stuck in the waist-shaped holes on the two slot plates 82.

[0034] When adjusting the drilling and tapping position of the workpiece, the electric push rod 83 can be started to extend its movable end along the slope of the supporting bracket 81, and at the same time push the drive shaft 84 to slide in the waist-shaped hole to lift the electric clamp 5, thereby changing the angle of the workpiece on the electric clamp 5, so that the drilling and tapping position of the workpiece can be adjusted more accurately.

[0035] Example III: Figure 2 and Figure 6 As shown, a cooling assembly 9 is provided on the dual-axis drilling rig 73, and the cooling assembly 9 includes a winding bracket 91, a positioning block 92 and a nozzle 93. The winding bracket 91 is fixedly installed on the right side of the dual-axis drilling rig 73 by bolts, and the water spraying end of the nozzle 93 is wound and fixed on the winding bracket 91. A positioning block 92 is fixedly provided on the top of the shell 2, and the water inlet end of the nozzle 93 passes through the right side wall of the shell 2 and is fixedly connected to the positioning block 92.

[0036] like Figure 2 and Figure 7 As shown, an adaptable component 10 is arranged on the top of the shell 2, and the adaptable component 10 includes a guide slide frame 101, a winding wheel 102 and an elastic member 103. The guide slide frame 101 is installed on the top of the shell 2, and the winding wheel 102 is slidably arranged on the guide slide frame 101. The tube body of the nozzle 93 is partially wound on the winding wheel 102, and an elastic member 103 is arranged between the winding wheel 102 and the guide slide frame 101. The elastic member 103 is set as a spring, and the elastic member 103 is initially in a compressed state, which can apply a leftward thrust to the winding wheel 102 and pull the nozzle 93 to keep it straight.

[0037] When the double-axis drilling rig 73 drills and taps the workpiece, a large amount of heat is generated. The water inlet end of the nozzle 93 is connected to the coolant. When the double-axis drilling rig 73 is running, the water spraying end of the nozzle 93 is used to spray the coolant to the drill bit of the double-axis drilling rig 73 and the workpiece, so as to protect the double-axis drilling rig 73 and the workpiece. When the double-axis drilling rig 73 moves to the right, the nozzle 93 is temporarily in a relaxed state, but then the elastic member 103 pushes the winding wheel 102 to move to the left, and pulls out the relaxed part of the nozzle 93, so that it continues to remain in a straight state. When the double-axis drilling rig 73 moves to the left, the nozzle 93 is pulled into the shell 2, which can also keep it in a straight state. Similarly, when the double-axis drilling rig 73 rotates with the ring gear 72, the nozzle 93 will also remain in a straight state, thereby preventing the nozzle 93 from falling onto the workpiece and causing obstacles to drilling and tapping.

[0038] Example IV: Figure 2 , Figure 8 and Fig. 9As shown, a support assembly 11 is arranged in the shell 2, and the support assembly 11 includes a transverse plate 111, a support folding frame 112 and an L-shaped push rod 113. The transverse plate 111 is fixedly arranged between the left and right inner walls of the shell 2 by bolts, and is located in front of the storage frame 3, and the height is consistent with the storage frame 3. A support folding frame 112 is arranged thereon, and the support folding frame 112 is divided into left and right parts, which are rotatably connected to each other. The left half is rotatably connected to the transverse plate 111, and the right half passes through the transverse plate 111 and is slidably connected to the transverse plate 111 through a spring, and an L-shaped push rod 113 is arranged at the bottom of the right half of the support folding frame 112, and the L-shaped push rod 113 is slidably matched with the transverse plate 111 and can contact the mounting ring 7.

[0039] The support folding frame 112 will initially be retracted under the action of the spring, and the rotating connection between the left and right parts will contact the storage frame 3, which can support the workpiece when the workpiece is clamped on the electric clamp 5 to prevent the workpiece from falling into the hollow base 1 due to operational errors of the workers, and when the double-axis drilling rig 73 moves to the right, the mounting ring 7 will contact the L-shaped push rod 113 and push the L-shaped push rod 113 to move to the right, and the L-shaped push rod 113 will then drive the right half of the support folding frame 112 to slide to the right, so that the support folding frame 112 is laid flat on the cross plate 111 and will not hinder the operation of the double-axis drilling rig 73. At the same time, the spring between the support folding frame 112 and the cross plate 111 will be compressed and stored. When the double-axis drilling rig 73 is reset later, the support folding frame 112 will be pushed to the retracted state again.

[0040] Example V: Figure 2 , Fig.10 and Fig.11 As shown, a shielding assembly 12 is provided on the shell 2, and the shielding assembly 12 includes a blocking cover 121, a slide rail 122, a clamping rod 123, a limiting column 124 and a latch 125. A blocking cover 121 is slidably provided on the front side of the shell 2, and a slide rail 122 is fixedly installed on the left side of the blocking cover 121. A socket is provided on the slide rail 122, and the clamping rod 123 is slidably provided on the slide rail 122. A limiting column 124 is also provided at the bottom of the front side of the shell 2, and the left end of the limiting column 124 passes through the left side wall of the shell 2. The clamping rod 123 cooperates with the limiting column 124 to prevent the blocking cover 121 from sliding to the left, and a latch 125 is provided on the clamping rod 123, and the latch 125 can pass through the clamping rod 123 and be inserted into the socket on the slide rail 122.

[0041] The dual-axis drilling rig 73 will generate a lot of debris during operation. The cover 121 is used to close the shell 2 to block the flying debris, which can facilitate centralized cleaning of the debris and prevent the flying debris from causing harm to workers. The clamping rod 123 is slid downward along the slide rail 122 until its bottom end is clamped on the limiting column 124, and the latch 125 is inserted into the socket at the corresponding position on the slide rail 122, so that the cover 121 can be limited and fixed, avoiding the worker from opening the cover 121 due to misoperation, thereby ensuring the safety of the device during operation.
