The side surface of the shell 52 needs to drill four bottom holes first, then tap, get four threaded holes two 522. The front end surface of the shell 52 directly drills four through holes 523.

[0026] As Figures 1-3As shown, the first drilling station, the second drilling station, the third drilling station, the empty position, the first tapping station and the second tapping station are evenly arranged in a ring shape in the clockwise direction inside the processing box. The processing box comprises a base 3, a box body 1 arranged on the base 3 and having an open bottom end, five installation covers 14 arranged at the remaining five stations except the empty position, a support 2 arranged on the base 3 and forming a chip removal channel between the bottom end of the box body 1 and the bottom end of the support 2, a protective cover 121 arranged on the periphery of the bevel gear 13 and used for rotating installation of the rotating shaft 12, a supporting plate 4 located below the support 2 and the box body 1, and a pneumatic cylinder 5 arranged on the base 3 and used for driving the supporting plate 4 to block upwardly or to move away from the chip removal channel downwardly. The top of the box body 1 is provided with five notches 102 respectively communicating with the five installation covers 14, and the side of the box body 1 is provided with an inlet and outlet, and the inlet and outlet are hingedly connected with a box door 101, and the box door 101 is provided with a handle, so as to facilitate opening and closing of the box door 101. When the shell 52 is drilled and tapped by the processing device, the box door 101 is closed. When the shell 52 is taken out or placed, the box door 101 is opened. The inlet and outlet are located below the outer side of the middle installation cover 14 among the five installation covers 14, i.e. the outer side of the first drilling station. The support 2 is provided with a bracket 10 for installation of the bevel gear 11.

[0027] The processing device comprises five groups of driving mechanisms respectively located at the remaining five stations except the empty position, and five groups of processing heads respectively driven by the five groups of driving mechanisms. The three groups 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 a drill bit one, the processing head at the second drilling station is a drill bit two, and the processing head at the third drilling station is a drill bit three 30, and a through hole 523 is processed by the drill bit three 30. The two groups of processing heads at the first tapping station and the second tapping station are both taps, wherein the tap at the first tapping station is a tap one, and the tap at the second tapping station is a tap two, the tap one is used for processing a threaded hole one 521 based on the bottom hole processed by the drill bit one, and the tap two is used for processing a threaded hole two 522 based on the bottom hole processed by the drill bit two.

[0028] As shown in Figure 2 and Figure 3 The adjusting device comprises a rotating disc 7, a bevel gear 11 arranged in the processing box, six groups of clamping and rotating mechanisms uniformly distributed around the rotating disc 7, and a driving device 6 for driving the rotating disc 7 to rotate. The driving device 6 comprises a driving motor and a speed reducer arranged on the support 2, the output end of the driving motor is connected with the input end of the speed reducer, and the output end of the speed reducer is connected with the rotating disc 7 through an output shaft, so as to drive the rotating disc 7 to rotate. The top of the rotating disc 7 is vertically provided with a connecting shaft 8 penetrating through the protective cover 121. The inner side of the box body 1 is provided with a fixing ring 9, and the top end of the connecting shaft 8 is rotatably arranged on the fixing ring 9, so as to improve the stability of the rotating disc 7. The rotating disc 7 and the bevel gear 11 are coaxially distributed, and the bevel gear 11 is located outside the rotating disc 7.

[0029] AsFigure 2 and Figure 3 As shown in the figure, the clamping rotating mechanism includes a rotating shaft 12 arranged at the outer periphery of the rotating disc 7, a bevel gear 13 arranged on the rotating shaft 12 and engaged with the bevel gear plate 11, and a clamping assembly arranged at the outer end of the rotating shaft 12. The self-rotating process of the bevel gear 13 will switch the rear side of the rotating direction of the shell 52 clamped by the clamping rotating mechanism to the top surface every 60° revolution around the bevel gear plate 11, and the clamping rotating mechanism will shake off the residual debris on the shell 52 during the rotating process. Metal debris will be generated during the drilling and tapping process of the shell 52. When the clamping rotating mechanism rotates around the rotating disc 7, the metal debris shaken off is blocked by the protective cover 121 and cannot enter the bevel gear 13 and the bevel gear plate 11, preventing interference with the meshing transmission of the bevel gear 13 and the bevel gear plate 11.

[0030] The drilling and tapping functions are integrated in one device in this embodiment, which can be intelligently manufactured and automatically adjust the shell 52 to different stations for drilling or tapping processing on the end surface and side surface of the shell 52. The processing efficiency and intelligent degree are high, and one shell 52 only needs one clamping operation, which is simple. Six shells 52 are clamped in sequence, and the clamping rotating mechanism is revolved around the rotating disc 7 by 60° each time. The clamped shell 52 is automatically adjusted to the state that the side surface of the adjacent side is upwardly distributed. The shell 52 can shake off the residual processing debris by centrifugal force during the self-rotation and revolution, reducing the influence on the subsequent processing and improving the cleanliness of the final product shell 52. In this embodiment, the worker then takes out the six finished product shells 52 in sequence after different processing of the shell 52 at different stations. The six clamping rotating mechanisms are adjusted to the initial state, and the next round of processing is prepared. For each odd number of revolutions of the clamping rotating mechanism around the rotating disc 7, such as the first, third, and fifth revolutions, the clamping rotating mechanism clamps the shell 52. For even number of revolutions around the rotating disc 7, the clamping rotating mechanism is idle after the finished product shell 52 is taken out. On the one hand, the metal debris that may be left on the clamping assembly is shaken off by centrifugal force during this process.
