Specific embodiments

[0025] Example 1, as Figures 1-8 shown, a drilling and tapping device for intelligent manufacturing of a motor housing proposed in this example includes a processing box, a processing device, and an adjusting device, and can perform drilling and tapping on the motor housing 52. Four bottom holes need to be drilled first on the rear end face of the housing 52, and then tapped to obtain four first threaded holes 521. Four bottom holes need to be drilled first on the side face of the housing 52, and then tapped to obtain four second threaded holes 522. Four through holes 523 are directly drilled on the front end face of the housing 52.

[0026] As Figures 1-3As shown in the figure, six workstations, namely the first drilling station, the second drilling station, the third drilling station, a vacant position, the first tapping station, and the second tapping station, are evenly arranged in a circular shape along the clockwise direction inside the processing box. The processing box includes a base 3, a box body 1 provided on the base 3 with an open bottom end, five mounting covers 14 respectively provided at the other five workstations except the vacant position, a support 2 provided on the base 3 and forming a chip falling channel between the bottom end and the bottom end of the box body 1, a protective cover 121 provided outside the bevel gear 13 and for the rotary installation of the rotating shaft 12, a pallet 4 located below the support 2 and the box body 1, and a cylinder 5 provided on the base 3 and driving the pallet 4 to seal upward or move away downward from the chip falling channel. The top of the box body 1 has five notches 102 respectively communicating with the five mounting covers 14. The side of the box body 1 has an inlet and outlet, and a box door 101 is hinged at the inlet and outlet. A handle is installed on the box door 101 for convenient opening and closing of the box door 101. When the processing device drills and taps the housing 52, the box door 101 is closed. When taking and placing the housing 52, the box door 101 is opened. The inlet and outlet are correspondingly located outside the middle mounting cover 14 among the five mounting covers 14, that is, outside the first drilling station. A bracket 10 for installing the bevel gear disk 11 is provided on the support 2.

[0027] The processing device includes five sets of driving mechanisms respectively located at the other five workstations except the vacant position and five sets of processing heads respectively driven by the five sets of driving mechanisms. The three sets of processing heads at the first drilling station, the second drilling station, and the third drilling station are all drill bits. The processing head at the first drilling station is drill bit one, the processing head at the second drilling station is drill bit two, and the processing head at the third drilling station is drill bit three 30. A through hole 523 is machined by drill bit three 30. The two sets of processing heads at the first tapping station and the second tapping station are both taps. Among them, the tap at the first tapping station is tap one, and the tap at the second tapping station is tap two. Tap one is used to machine a threaded hole one 521 on the basis of the bottom hole machined by drill bit one, and tap two is used to machine a threaded hole two 522 on the basis of the bottom hole machined by drill bit two.

[0028] As Figure 2 and Figure 3 shown in the figure, the adjusting device includes a turntable 7, a bevel gear disk 11 provided inside the processing box, six sets of clamping and rotating mechanisms evenly distributed around the turntable 7, and a driving device 6 for driving the turntable 7 to rotate. The driving device 6 includes a driving motor and a speed reducer provided on the support 2. The output end of the driving motor is connected to the input end of the speed reducer, and the output end of the speed reducer is connected to the turntable 7 through an output shaft to drive the turntable 7 to rotate. A connecting shaft 8 is vertically provided at the top of the turntable 7, and the connecting shaft 8 penetrates through the protective cover 121. A fixing ring 9 is installed at the inner top end of the box body 1, and the top end of the connecting shaft 8 is rotatably provided on the fixing ring 9 to improve the rotation stability of the turntable 7. The turntable 7 and the bevel gear disk 11 are coaxially distributed, and the bevel gear disk 11 is located outside the turntable 7.

[0029] AsFigure 2 and Figure 3 As shown in Figure 3 , the clamping and rotating mechanism includes a rotating shaft 12 rotatably arranged on the outer periphery of the turntable 7, a bevel gear 13 arranged on the rotating shaft 12 and meshing with the bevel gear disk 11, and a clamping assembly arranged at the outer end of the rotating shaft 12. Every time the bevel gear 13 revolves around the bevel gear disk 11 by 60°, during the self-rotation process, the rear side of the rotating direction of the housing 52 clamped by the clamping and rotating mechanism is switched to the top surface. During the rotation process of the clamping and rotating mechanism, the residual debris on the housing 52 is thrown off. When drilling and tapping the housing 52, metal debris will be generated. When the clamping and rotating mechanism rotates self and revolves around the turntable 7, the thrown-off metal debris is blocked by the protective cover 121 and will not enter the bevel gear 13 and the bevel gear disk 11, preventing interference with the meshing transmission of the bevel gear 13 and the bevel gear disk 11.

[0030] In this embodiment, the drilling and tapping functions are integrated on one device, which can perform intelligent manufacturing, automatically adjust the housing 52 to different workstations, drill or tap the end face and side face of the housing 52 at multiple workstations, with high processing efficiency and intelligence level. Only one clamping and disassembling operation is required for one housing 52, and the operation is simple. First, six housings 52 are clamped in sequence. Each time the clamping and rotating mechanism revolves around the turntable 7 by 60°, the clamped housing 52 is automatically adjusted to the state where the adjacent side surface faces up. During the self-rotation and revolution of the housing 52, the residual processing debris can be thrown off by centrifugal force, reducing the influence on subsequent processing and improving the cleanliness of the final finished housing 52. In this embodiment, different processing is performed on the housing 52 at different workstations, and then the worker removes the six finished housings 52 in sequence. The six sets of clamping and rotating mechanisms are readjusted to the initial state to prepare for the next round of processing. For the odd-numbered revolutions of each set of clamping and rotating mechanisms around the turntable 7, such as the first revolution, the third revolution, the fifth revolution, etc., the housing 52 is clamped thereon; for the even-numbered revolutions around the turntable 7, it is an idle rotation after removing the finished housing 52. On the one hand, during this process, the metal debris that may remain on the clamping assembly is thrown off by centrifugal force. On the other hand, the six sets of clamping and rotating mechanisms can be adjusted to the initial state of the initial position.

[0031] The processing steps of this drilling and tapping equipment for intelligent manufacturing of motor housings are as follows:

Repeat S1 - S10 to perform the next round of processing.

[0043] Embodiment 2, as Figures 1-8 shown, a drilling and tapping device for intelligent manufacturing of a motor housing proposed in this embodiment. Compared with Embodiment 1, in this embodiment, every time the bevel gear 13 revolves 60° around the bevel gear disk 11, during the self - rotation process, the rear side of the housing 52 clamped by the clamping and rotating mechanism is switched to the top surface, that is, the bevel gear 13 self - rotates q and a quarter of a turn, and (q + 0.25)Z1 = Z2 / 6 is obtained.

[0044] The transmission ratio i of the bevel gear 13 and the bevel gear disk 11 is i = Z2 / Z1 = 3(4q + 1) / 2.

[0045] Wherein, Z1 is the number of teeth of the bevel gear 13, Z2 is the number of teeth of the bevel gear disk 11, q is the complete number of turns of the bevel gear 13 during its 60° revolution around the bevel gear disk 11, and Z1, Z2, and q are all positive integers.

[0046] In this embodiment, by specifically calculating the transmission ratio of the bevel gear 13 and the bevel gear disk 11, the part specifications capable of realizing the required motion are obtained, and the design is reasonable.

[0047] Embodiment 3, as Figures 1-8As shown in the figure, a drilling and tapping device for intelligent manufacturing of a motor housing proposed in this embodiment. Compared with the first embodiment, in this embodiment, the clamping assembly includes a rotating frame 40 provided at the outer end of the rotating shaft 12, a guide rod 51 provided on the rotating frame 40, a lead screw 50 parallel to the guide rod 51 and rotatably provided on the rotating frame 40, a moving plate 46 slidably provided on the guide rod 51 and threadedly connected to the lead screw 50, and a driving assembly for driving the lead screw 50 to rotate. The driving assembly includes a gear cover 48 provided on the rotating frame 40, two straight bevel gears located inside the gear cover 48 and meshingly connected, and a crank 49 rotatably provided on the rotating frame 40. The two straight bevel gears are respectively connected to the crank 49 and the end of the lead screw 50. Workers rotate the crank 49 to achieve the forward and reverse rotation of the lead screw 50. The lead screw 50 drives the moving plate 46 to move, and the guide rod 51 guides the linear movement of the moving plate 46. The moving plate 46 is used to press the rear end face of the motor housing 52 to be processed.

[0048] As Figure 4 shown, a first clamping platform 41 is detachably connected to the inner end surface of one side of the rotating frame 40, and a second clamping platform 47 opposite to the first clamping platform 41 is detachably connected to the moving plate 46. Both the first clamping platform 41 and the second clamping platform 47 are circular bosses. The housing 52 to be processed is clamped onto the first clamping platform 41. By rotating the crank 49, the moving plate 46 drives the second clamping platform 47 to move, and the second clamping platform 47 is clamped inside the other end of the housing 52, improving the reliability of clamping the housing 52. For housings 52 of different sizes, corresponding-sized clamping platforms are selected and installed on the rotating frame 40 and the moving plate 46. For the detachable connection of the clamping platforms, internal threads can be designed on the rotating frame 40 and the moving plate 46, and through holes are provided on the clamping platforms. The clamping platforms are pressed by screwing screws through the through holes and into the internal threads, achieving detachable installation.

[0049] As Figure 4 shown, a sliding rod 43 is slidably provided on the rotating frame 40. One end of the sliding rod 43 is connected to a button 44, and the other end is connected to a pushing platform 42 for straightening the housing 52. A spring 45 is sleeved on the outer periphery of the sliding rod 43, and both ends of the spring 45 are respectively connected to the rotating frame 40 and the pushing platform 42. Before the housing 52 is clamped onto the first clamping platform 41, the button 44 is pulled outwards, and the spring 45 is compressed. After the housing 52 is clamped onto the first clamping platform 41, the button 44 is pushed forward. The button 44 drives the pushing platform 42 to move forward. The pushing platform 42 adjusts the orientation of the housing 52 by pushing the side surface of the housing 52, regularizes and positions the housing 52, and then the second clamping platform 42 is clamped into the housing 52 by rotating the crank 49, and the moving plate 46 is used to press the housing 52. In addition to playing a role in clamping and positioning, the clamping platforms on both sides can also block both ends of the housing 52, preventing debris generated during the drilling and tapping processes from entering the inside of the housing 52.

[0050] In this embodiment, the clamping assembly is used to clamp the housing 52, and the positioning is carried out by using the clamping platform and the pushing platform 42, so as to improve the clamping reliability during processing, ensure accurate drilling and tapping during subsequent processing, and ensure the processing quality.

The first driving gear, the second driving gear, the driven gear 23, the first gear, the second gear and the transmission gear 19 are all located inside the lifting cover 17 and can be effectively protected.

[0054] As Figure 5 and Figure 6 shown in the figure, the adjusting assembly includes a support column 31 arranged at the bottom of the lifting cover 17, a swivel ring 32 rotatably arranged at the bottom of the support column 31, a connecting frame 33 arranged on the support column 31, a sliding cylinder 34 arranged on the connecting frame 33, a sliding table 35 slidably arranged on the sliding cylinder 34, a threaded knob 36 threadedly connected to the sliding cylinder 34 and rotatably connected to the sliding table 35, a second slide rail 37 arranged at the bottom of the swivel ring 32, a second slider 38 slidably arranged on the second slide rail 37 and connected to the mounting seat 29, and a bolt 39 threadedly connected to the mounting seat 29 and passing through the second slider 38. By rotating the threaded knob 36, the sliding table 35 can be driven to slide. The front end of the sliding table 35 is an arc-shaped groove, which can abut against the outer peripheral surface of the swivel ring 32 to limit the swivel ring 32 that has been adjusted in rotation. In addition, the bolt 39 can also be rotated to abut against the second slide rail 37 to limit the second slider 38 and determine the position of the second slider 38 on the second slide rail 37, thereby determining the position of the mounting seat 29. Plug blocks can be added at the front and rear ends of the second slide rail 37 to prevent the second slider 38 from slipping. Multiple second sliders 38 can be added, and multiple bolts 39 are correspondingly arranged. The multiple bolts 39 jointly abut against the second slide rail 37 to improve the limiting effect of abutting.

[0055] In this embodiment, the distribution of the processing heads can be adjusted through the adjusting assembly to flexibly adjust according to the processing requirements at different positions on the housing 52, with a large application range. Workers need to adjust each drill bit and tap in place before processing the housing 52.

[0056] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto, and various changes can be made without departing from the spirit of the present invention within the scope of knowledge possessed by those skilled in the relevant art.
