[0003] The existing multi-hole drilling and tapping integrated machine needs to process different materials during drilling and tapping operation, and different materials or thicknesses of materials need to be tapped and retreated during tapping operation. The existing drilling and tapping integrated machine can achieve tapping and retreating operation through programming, but in actual use, workers usually use the same program from the beginning to the end in a factory where materials are frequently changed, which causes the retreating step of materials that do not need to retreat during processing, and leads to a long processing cycle of the materials, and the tools of some materials that need to be frequently retreated for tapping are not retreated, which leads to accelerated tool wear.
[0004] The present application provides a new solution to solve the above problems. SUMMARY

[0022] Compared with the prior art, the beneficial effects of the present application are as follows: the rotating force is transmitted to the rotating shaft along the transmission shaft through the motor, when the rotating shaft encounters a large resistance, the force transmitted by the motor cannot be completely transmitted to the rotating shaft to offset the resistance, so that the transmission shaft is blocked by the rotating shaft to form a force away from the rotating shaft, and since the transmission shaft is installed on the rotating frame, the rotating frame is pushed, the rotating wheel at the other end of the rotating frame is engaged with the rotating shaft after the rotating frame is pushed, and since the rotating wheel is engaged with the transmission shaft, the rotating direction of the rotating wheel is opposite to that of the transmission shaft, when the rotating wheel is engaged with the rotating shaft, the rotating wheel drives the rotating shaft to rotate in the opposite direction, so that the rotating shaft is separated from the processing point of the material, and after the separation, the transmission shaft is engaged with the rotating shaft again under the action of the reset mechanism, so that the effect of simulating manual tapping is realized, when the material hardness is high, the frequency of turning over is increased, and when the material hardness is low, the rotating force of the transmission shaft can be smoothly transmitted to the rotating shaft, and the rotating shaft rotates normally, so that the drill bit does not need to be reset to reduce the resistance of the next drill bit.

DETAILED DESCRIPTION
[0029] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. In the description of the present application, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, and are only used to facilitate the description of the present application and simplify the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.
[0030] As shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , a multi-hole drilling and tapping integrated machine comprises:
[0031] Machine base 1; the main body of the device, used to carry various components;
[0032] Rotating shaft 2, rotatably mounted on machine base 1, used to transmit the rotating force of the motor to drill bit 31;
[0033] The rotating frame 41 is rotatably mounted on the base 1 and used for mounting the connecting structure between the motor and the rotating shaft 2.
[0034] The transmission shaft 42 is rotatably mounted on the rotating frame 41, one end of which is engaged with the output end of the motor and the other end of which is in transmission connection with the rotating shaft 2.
[0035] The rotating wheel 43 is rotatably mounted on the rotating frame 41, in transmission connection with the transmission shaft 42 and in transmission connection with the rotating shaft 2 after the rotating frame 41 is rotated.
[0036] The reset mechanism is mounted between the rotating frame 41 and the base 1 and used for keeping the transmission shaft 42 in transmission with the rotating shaft 2.
[0037] The delay mechanism is mounted on the base 1 and used for prolonging the separation time of the transmission shaft 42 and the rotating shaft 2 to ensure that the rotating wheel 43 has enough time to transmit the rotating shaft 2.
[0038] The drilling platform 3 is detachably mounted on the base 1 and provided with a transmission hole for being in transmission connection with the rotating shaft 2.
[0039] The rotating frame 41 is arranged in an arc shape, the transmission shaft 42 and the rotating wheel 43 are respectively mounted at the two ends of the arc shape and engaged with each other, the middle part of the rotating frame 41 is in rotation connection with the base 1, and the reset mechanism is arranged at the side where the rotating frame 41 is connected with the rotating shaft 2.
[0040] When the product is used, the drilling platform 3 is installed according to the need, and after the drilling platform 3 is installed, the material can be processed. The product outputs constant revolutions through the motor, and performs drilling and tapping actions on the material. When the hole is turned, the metal chips are continuously cut, so that the resistance received during drilling is in a dynamic balance. When the drilling head of the drilling hole passes through the material, the tapping cone in the middle of the drill bit 31 contacts the material. At this time, the tapping cone uses extrusion to generate threads on the material, and a large friction is generated between the tapping cone and the material. At this time, the increase of the friction between the tapping cone and the material will cause the resistance received by the rotating shaft 2 during rotation to increase. When the resistance between the tapping cone and the material is greater than the force transmitted to the rotating shaft 2 by the transmission shaft 42, the force in the direction away from the rotating shaft 2 is greater than the force of the reset mechanism pulling the rotating frame 41, the reset mechanism cannot pull the rotating frame 41, causing the rotating frame 41 to be pushed, so that one end of the arc-shaped rotating frame 41 is raised, and the other end is pushed to the rotating shaft 2, so that the rotating wheel 43 engages with the rotating shaft 2, thereby pushing the rotating shaft 2 to reverse. Since the tapping cone needs to extrude the material to form threads when advancing, but does not need to extrude the material when retreating, the required force is smaller, so that the tapping cone can retreat smoothly. In order to increase the retreat distance, so that the lubricating oil can better penetrate into the material hole, the product is designed with a delay mechanism, which delays the rebound time of the rotating frame 41, so that the rotating wheel 43 can keep the transmission time of the rotating shaft 2 longer, thereby better transmitting power to the rotating shaft 2, achieving the effect of driving the tapping cone to retreat.
[0041] In the embodiment, the reset mechanism includes a tension spring fixed with the rotating frame 41 and an adjusting bolt 62 threadedly connected with the base 1. One end of the adjusting bolt 62 penetrates the base 1 and is fixedly connected with the tension spring through a rotating ring. The adjusting bolt 62 is used to adjust the stretching degree of the tension spring, so that the tension of the tension spring keeps the transmission shaft 42 in the state of being attached to the rotating shaft 2. The adjusting bolt 62 is adjusted conveniently and quickly, and only needs to be adjusted according to the material quality, without the need to adjust according to the thickness, thereby greatly increasing the universality.
[0042] In this embodiment, the delay mechanism includes an energy storage assembly and a latch 56, the latch 56 has an inclined surface, the latch 56 can be inserted into the rotating frame 41 by the thrust of the energy storage assembly to further rotate the rotating frame 41, the rotating frame 41 is provided with a insertion hole 44, the insertion hole 44 is inclinedly arranged and can be in abutment transmission with the latch 56, the energy storage assembly includes an energy storage wheel 51 in meshing transmission with the rotating shaft 2 and an air pump 52 coaxial with the energy storage wheel 51 and in one-way transmission, and a sliding cylinder for sliding the latch 56, the air pump 52 and the sliding cylinder are communicated through an air storage cavity, the sliding cylinder is provided with a air exhaust pipe 57, the air exhaust pipe 57 is provided with an air exhaust hole, and the air exhaust pipe 57 is threadedly connected with an air exhaust bolt 58 capable of moving to overlap and seal the air exhaust hole, the energy storage wheel 51 is in meshing transmission with the rotating shaft 2, so that the rotating shaft 2 transmits the rotating force to the energy storage wheel 51, then the energy storage wheel 51 drives the air pump 52 to rotate, the air pump 52 pumps air into the sliding cavity 53, at this time, since the rotating frame 41 does not rotate, the latch 56 abuts against the surface of the rotating frame 41, and since the air pump 52 continuously rotates, air is continuously pumped into the sliding cavity 53 for storage, and the air exhaust pipe 57 is provided with an air exhaust hole capable of slowly discharging air, and the air exhaust valve 55 is arranged on one side of the air exhaust pipe 57, when the stored pressure is too large and the air exhaust hole cannot discharge air in time, the air exhaust valve 55 can quickly reduce the air pressure, thereby avoiding damage caused by excessive pressure in the sliding cavity 53, and when the rotating frame 41 rotates, when the rotating frame 41 rotates to the position where the latch 56 can be inserted into the insertion hole 44, at this time, due to the effect of the air pressure in the sliding cavity 53, the latch 56 further quickly pushes the rotating frame 41 away from the rotating shaft 2, thereby making the rotating wheel 43 more quickly contact the rotating shaft 2, so as to realize the action of tool withdrawal, and because of the air exhaust hole on the rotating shaft 2 and the one-way transmission effect of the energy storage wheel 51 and the air pump 52, when the rotating shaft 2 reversely rotates, the energy storage wheel 51 does not transmit the rotating force to the air pump 52, at this time, the air pump 52 does not pump air any more, and the air in the sliding cavity 53 is gradually reduced under the discharge of the air exhaust hole, and since the force of the spring 61 on the reset device remains unchanged, after the pressure provided by the sliding cavity 53 is reduced, the abutment force between the latch 56 and the insertion hole 44 is reduced, so that the reset mechanism can pull the rotating frame 41 to rotate, when the pressure in the sliding cavity 53 is insufficient to support the rotating frame 41, the rotating frame 41 is reset to the position where the transmission shaft 42 is in meshing transmission with the rotating shaft 2, at this time, one cutting and tool withdrawal action is completed, and due to the effect of the screw thread, neither the tool withdrawal nor the cutting needs external force in the vertical direction, thereby realizing automatic cutting and tool withdrawal, until the tapping is completed, the operator manually withdraws the tool to separate the drill and the material.
[0043] Wherein the air pump 52 in the energy storage assembly can be replaced by a piston pump 54 or an air motor.
[0044] The drilling platform 3 comprises a housing and a drill bit 31 movably arranged in the housing and a synchronous chain 32 arranged in the housing and connected with the drill bit 31, since the position of each drilling tap will change with the position of the material, the drilling platform 3 of the product drives the drill bit 31 in the drilling platform 3 through the synchronous chain 32, then limits the drill bit 31 through the modular drill bit clamp 33, and simultaneously drives the drill bit 31 to change the position, so that the drill bit 31 can be slid to any position of the drilling platform 3 for fixation, so that the rotating shaft 2 can be inserted into the drilling platform 3 through the transmission hole and engaged with the trapezoidal synchronous chain 32, then drive the synchronous chain 32 to move, when the synchronous chain 32 moves, the drill bit 31 engaged with the synchronous chain 32 is pushed, so as to realize the effect of synchronous rotation of all drill bits 31, and through the characteristic that the drill bit clamp 33 can drive the drill bit 31 to move, the drill bit 31 can be adapted to the material.
[0045] It will be obvious to a person skilled in the art that, as the application is not limited to the details of the exemplary embodiments described above, the application can be implemented in other concrete forms without departing from the spirit or essential characteristics of the application. Therefore, the embodiments should be considered in all respects as illustrative and not restrictive, and the scope of the application should be defined by the appended claims rather than by the above description, and it is therefore intended to embrace all changes and modifications of the application that fall within the meaning and scope of equivalents of the claims. Any reference signs in the claims should not be considered as limiting the claims involved.
[0046] In addition, it should be understood that, although the present specification is described in terms of embodiments, not every embodiment contains only one independent technical solution, and the description of the specification is only for the sake of clarity, and those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can be appropriately combined to form other embodiments that those skilled in the art can understand.
