[0047] The drilling and tapping assembly 57 includes an elastic telescopic rod 571, which is fixedly connected to the inside of the connecting disk 56. The bottom end of the elastic telescopic rod 571 is fixedly connected to a drilling and tapping piece 572. Folding strips 573 are symmetrically connected to both sides of the drilling and tapping piece 572. The bottom of the folding strip 573 is squeezed and adapted to the inflatable cushion 404. The outer side of the drilling and tapping piece 572 is fixedly connected to an outer connecting strip 574. Then, the rotating table 55 is started again, so that the connecting disk 56 connected to the rotating part thereof will rotate, and the drilling and tapping assembly 57 arranged on the connecting disk 56 will rotate accordingly. Then, the corresponding drilling and tapping assembly 57 is selected to be located above the clamping table 44. There are three drilling and tapping assemblies 57, and the drilling and tapping heads are inconsistent. Therefore, the required drilling and tapping head is selected by rotating the connecting disk 56. When the selection is completed, the servo motor 52 is started again, so that the No. 2 screw rod 53 connected to its output end through the coupling will rotate forward, and the slider 54 threadedly connected to the outer side of the No. 2 screw rod 53 will move downward with the rotating table 55, so the entire drilling and tapping assembly 57 will move downward, wherein the drilling and tapping assembly 57 includes an elastic telescopic rod 571, and the bottom end of the elastic telescopic rod 571 is fixedly connected to a drilling and tapping piece 572, wherein the elastic telescopic rod 571 is in a contracted state when not drilling, and is elastic itself, and then the outer connecting bar 574 fixedly connected to the outer side of the drilling and tapping piece 572 will move downward, thereby playing a role in preparing for subsequent drilling and tapping processing, wherein the drilling and tapping piece 572 is a set of drilling equipment, which generally covers components such as a rotary drive, a fixing part and a drill bit.

[0048] The limited slip assembly 58 includes a limited slip frame 581, the outer side of the limited slip frame 581 is fixedly connected to the outer connecting bar 574, the inner side of the limited slip frame 581 is fixedly connected to a soil-like block 582, the two ends of the soil-like block 582 are symmetrically connected to magnets 583, an end of the magnet 583 away from the soil-like block 582 is provided with an electromagnet 584, the electromagnet 584 is inserted into the soil-like block 582, and the end of the electromagnet 584 away from the soil-like block 582 is fixedly connected to a compensation rod 585, and the outer side of the compensation rod 585 is fixedly connected to the outer side of the compensation rod 585.

The bottom of the support plate 587 is fixedly connected with a bottom plate 588, and the bottom of the bottom plate 588 is fixedly connected with a hydraulic rod 589. The bottom end of the hydraulic rod 589 is fixedly connected with a post plate 580, and the post plate 580 is fixedly connected to the top of the built-in platform 3. As the drilling and tapping piece 572 moves downward with the external connecting strip 574, When the outer connecting bar 574 is in the state of being moved, the bottom plate 588 connected to the outer connecting bar 574 and the bottom plate 588 are moved downwards, and the outer connecting bar 574 is fixedly connected to the inner side of the limiting frame 581, and the two ends of the soil-like block 582 are symmetrically connected with magnets 583. Therefore, when the soil-like block 582 moves to the same height as the compensation rod 585, the electromagnet 584 is started, so that the electromagnet 584 and the magnet 583 are attracted to each other, and then the electromagnet 584 passes through the support plate 587 and compresses the return spring 586, wherein the return spring 586 plays a role in resetting the electromagnet 584 until it enters the soil-like block 582 to achieve the purpose of connecting the two to each other. Finally, the hydraulic rod 589 is started, so that the bottom plate 588 connected to the top thereof will move downwards with the support plate 587, and finally the outer connecting bar 574 will move downwards with the drilling and tapping piece 572, and stretch the elastic telescopic rod 571, thereby playing the role of moving the drilling and tapping piece 572 downwards to drill the generator box cover. In addition, the function of the limited-slip assembly 58 is not only to drive the drilling and tapping component 572 to drill the generator case cover, but also to position and lock the replaced drilling and tapping assembly 57. In addition, the combination of the drilling and tapping assembly 57 and the limited-slip assembly 58 can also prevent the drill bits on both sides from interfering with the center drill bit during processing due to the three drill bits being too long and only the downward movement of the slider 54.

[0049] like Fig. 9 , Fig.10 , Fig.11 , Fig.12 , Fig.13 and Fig.14As shown, the cleaning mechanism 6 includes a water storage frame 61, which is fixedly installed on the top of the built-in table 3, a pump body 62 is fixedly installed on the outer side of the water storage frame 61, and the end of the pump body 62 away from the water storage frame 61 is fixedly connected to a water inlet pipe 63, and the side of the water storage frame 61 away from the pump body 62 is fixedly connected to a cooling nozzle 64, and the bottom of the rotating table 55 is fixedly connected to a first folding plate 65, and the bottom end of the first folding plate 65 is plugged with a plate sleeve 66, and the bottom end of the plate sleeve 66 is sleeved with a second folding plate 67, and the outer side of the second folding plate 67 A sliding rod 68 is fixedly connected, and one end of the sliding rod 68 away from the second folding plate 67 is fixedly connected to an arc sleeve 69, wherein an arc hole is opened on the outside of the water storage frame 61, and the sliding rod 68 is slidably adapted in the arc hole, and the central part of the arc sleeve 69 is fixedly connected to a center plate, and the two ends of the arc sleeve 69 are symmetrically inserted with arc rods 60, and the end of the arc rod 60 close to the arc sleeve 69 is fixedly connected to an elastic strip 601, and the end of the elastic strip 601 away from the arc rod 60 is fixedly connected to the center plate, and the arc rod 6 The end of the through-hole plate 602 away from the arc-shaped sleeve 69 is fixedly connected, and the outer side of the through-hole plate 602 is slidably adapted to be equipped with a ring rail 603, and the ring rail 603 is fixedly connected to the inside of the water storage frame 61. Through the clockwise rotation of the rotating platform 55, the first folding plate 65 fixedly connected to the bottom thereof will be instantly deflected, and the second folding plate 67 connected to the first folding plate 65 through the plate sleeve 66 will rotate accordingly, wherein the plate sleeve 66 is respectively sleeved on the first folding plate 65 and the second folding plate 67, and the same At this time, the plate sleeve 66 plays a role in compensating the distance between the two folding plates, wherein the sliding rod 68 connected to the other side of the second folding plate 67 will cause the arc sleeve 69 to deflect upward in an arc shape, and then the arc rod 60 connected to the center plate at the center of the arc sleeve 69 through the elastic strip 601 will deflect upward accordingly, and the through-hole plate 602 fixedly connected to the other end of the arc rod 60 will move to the center position of the annular rail 603 and coincide with the part where the cooling nozzle 64 is connected to the water storage frame 61. There are two elastic strips 601, arc rods 60 and through-hole plates 602, and they are symmetrically arranged at the two ends of the arc sleeve 69. Therefore, when the arc sleeve 69 deflects upward, the elastic strip 601 at its left end will remain unchanged and move upward with the arc rod 60 and the through-hole plate 602, but the elastic strip 601 at its right end will be compressed, and the arc sleeve 69 will cover the arc rod 60 at the right end. In addition, when the arc sleeve 69 deflects downward, the above components will move in the opposite direction. The holes on the surfaces of the other two through-hole plates 602 are of different sizes. The diameter of the hole on the surface of the through-hole plate 602 at the left end is larger than the diameter of the hole on the surface of the cooling nozzle 64 and the through-hole plate 602 at the right end, and the inner diameter of the cooling nozzle 64 is larger than the hole on the surface of the through-hole plate 602 at the right end.

[0050] The inner diameters of the two through-hole plates 602 and the cooling nozzle 64 correspond to the three drilling and tapping components 57 respectively. The through-hole plate 602 with a small aperture corresponds to a fine drilling head, while the through-hole plate 602 with a large aperture corresponds to a coarse drilling head. The purpose of the small aperture corresponding to the fine drilling head is to avoid excessive spraying of coolant to cause waste or affect the drilling speed.

[0051] When the present invention is in use: first, the engine case cover is placed into the clamping table 44, and then the small motor 43 is started, so that the No. 1 screw rod 42 connected to its output end through a coupling will rotate forward, and the clamping table 44 threadedly connected to the outer side of the No. 1 screw rod 42 will move to the bottom of the drilling and tapping mechanism 5. Then, the rotating table 55 is started again, so that the connecting disk 56 connected to the rotating part thereof will rotate, and the drilling and tapping assembly 57 arranged on the connecting disk 56 will rotate, and the corresponding drilling and tapping assembly 57 will be selected to be located above the clamping table 44. When the selection is completed, the servo motor 52 is started again, so that the No. 2 screw rod 53 connected to its output end through the coupling will rotate forward, and the slider 54 threadedly connected to the outer side of the No. 2 screw rod 53 will move downward with the rotating table 55, so that the entire drilling and tapping assembly 57 will move downward, wherein the drilling and tapping assembly 57 includes an elastic telescopic rod 571, and the bottom end of the elastic telescopic rod 571 is fixedly connected to a drilling and tapping part 572, and then the outer connecting bar 574 fixedly connected to the outer side of the drilling and tapping part 572 will move downward, thereby realizing the secondary control and positioning processing of the drilling and tapping part 572.

[0052] As the drilling and tapping piece 572 moves downward with the outer connecting bar 574, the sliding limit frame 581 fixedly connected to the other end of the outer connecting bar 574 will move downward, and the inner side of the sliding limit frame 581 is fixedly connected with a soil-like block 582, and both ends of the soil-like block 582 are symmetrically connected with magnets 583. Therefore, when the soil-like block 582 moves to the same height as the compensation rod 585, the electromagnet 584 is started, resulting in attraction between the electromagnet 584 and the magnet 583, and then the electromagnet 584 will pass through the support plate 587 and compress the return spring 586 until it enters the soil-like block 582 to achieve the connection processing, and finally the hydraulic rod 589 is started, so that the bottom plate 588 connected to the top thereof will move downward with the support plate 587, and finally the outer connecting bar 574 will move downward with the drilling and tapping piece 572 and stretch the elastic telescopic rod 571, thereby achieving the drilling and tapping processing of the engine cover. In addition, through the downward movement of the drilling and tapping part 572, the folding strips 573 fixedly connected on both sides thereof will move downward, and squeeze and compress the inflatable cushion 404, and then the gas inside the inflatable cushion 404 will enter the interior of the No. 1 support rod 401 through the No. 2 support rod 403 and the cross bar 402 in turn, and the top of the No. 1 support rod 49 is inserted, so the force-bearing rod 49 squeezed by the gas will move upward with the universal head 48, and squeeze the clamping plate 47 upward, and then the clamping plate 47 will be deflected inward through the support 46, thereby realizing the secondary clamping of the engine cover.

[0053] By rotating the rotating table 55 clockwise, the folding plate No. 1 65 fixedly connected to its bottom will be instantly deflected, and the folding plate No. 2 67 connected to the folding plate No. 1 65 through the plate sleeve 66 will rotate accordingly, and the sliding rod 68 connected to the other side of the folding plate No. 2 67 will lead the arc sleeve 69 to deflect upward in an arc shape, and then the arc rod 60 connected to the arc sleeve 69 through the elastic strip 601 will be deflected upward, and the through-hole plate 602 fixedly connected to the other end of the arc rod 60 will move to the center position of the annular rail 603 and coincide with the part where the cooling nozzle 64 is connected to the water storage frame 61.

[0054] The above-mentioned embodiments are only preferred embodiments of the present invention, and cannot be used to limit the scope of protection of the present invention. Various changes made by ordinary technicians in this field based on the above-mentioned concepts without creative work all fall within the scope of protection of the present invention.
