Description

Technical Field

[0001] The invention discloses a multi-hole drilling and tapping integrated machine, belonging to the field of mechanical processing equipment. Background Art

[0002] The multi-hole drilling and tapping machine is a drilling and tapping machine equipped with multiple drill bits, which is used to perform thread processing in the hole simultaneously while drilling.

[0003] The existing multi-hole drilling and tapping machines, when performing drilling and tapping operations, have different materials to be processed. When tapping materials of different materials or thicknesses, some need to tap and retract to perform the tapping operation. Although the existing drilling and tapping machines can achieve the tap and retract action effect by relying on programming, in actual use, in factories where materials are frequently changed, workers usually use the same program from beginning to end, which causes the materials that do not need to be retracted to have a retracting step during processing, resulting in a longer processing cycle of the material, while some materials that require frequent retracting for tapping are not retracted, resulting in accelerated tool wear.

[0004] A new solution is now proposed to solve the above problems. Summary of the invention

[0005] The purpose of the present invention is to provide a multi-hole drilling and tapping machine in order to solve the above-mentioned problems.

[0006] The present invention achieves the above-mentioned purpose through the following technical solutions, a multi-hole drilling and tapping machine, comprising: Machine base: the main body of the equipment, used to carry various components; A rotating shaft is rotatably mounted on the machine base and is used to transmit the rotational force of the motor to the drill bit; A rotating frame is rotatably mounted on the machine base and is used to install the connection structure between the motor and the rotating shaft; The transmission shaft is rotatably mounted on the rotating frame, one end of which is meshed with the output end of the motor and the other end is transmission-connected with the rotating shaft; The rotary wheel is rotatably mounted on the rotating frame, meshes with the transmission shaft for transmission, and is transmission-connected with the rotating shaft after the rotating frame rotates; The reset mechanism is installed between the rotating frame and the base, and is used to maintain the transmission shaft and the rotating shaft; The delay mechanism is installed on the machine base and is used to extend the separation time when the transmission shaft and the rotating shaft are rotating and separated to ensure that the rotary wheel has enough time to transmit the rotation to the rotating shaft; The drilling platform is detachably mounted on the machine base and is provided with a transmission hole for transmission connection with the rotating shaft.

[0007] Preferably, the rotating frame is arc-shaped, and a drive shaft and a rotary wheel that mesh with each other are respectively installed at both ends of the arc. The middle of the rotating frame is rotatably connected to the machine base, and the reset mechanism is arranged on the side where the rotating frame is connected to the drive shaft.

[0008] Preferably, the reset mechanism includes a tension spring fixed to the rotating frame and an adjusting bolt threadedly connected to the machine base. One end of the adjusting bolt passing through the machine base is fixedly connected to the tension spring through a rotating ring.

[0009] Preferably, the delay mechanism includes an energy storage component and a bolt. The bolt can be inserted into the rotating frame under the thrust of the energy storage component to cause the rotating frame to rotate further.

[0010] Preferably, the rotating frame is provided with a jack, the jack is inclined, and can be in contact with the bolt for transmission.

[0011] Preferably, the energy storage component includes an energy storage wheel meshing and driving with the rotating shaft, an air pump coaxially and unidirectionally driving with the energy storage wheel, and a sliding cylinder for the bolt to slide. The air pump and the sliding cylinder are communicated through an air storage cavity.

[0012] Preferably, the sliding cylinder is provided with an air discharge pipe, the air discharge pipe is provided with an air discharge hole, and an air discharge bolt that can move to overlap and seal with the air discharge hole is threadedly connected in the air discharge pipe.

[0013] Preferably, the drilling table includes a housing, a drill bit movable inside the housing, and a synchronous chain connecting the drill bits in series inside the housing.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: The rotational force is transmitted from the motor along the drive shaft to the rotating shaft. When the resistance of the rotating shaft is relatively large, the force transmitted by the motor at this time cannot be completely transmitted to the rotating shaft to offset the resistance, which will cause the drive shaft to be blocked by the rotating shaft and form a force away from the rotating shaft. And because the drive shaft is installed on the rotating frame, the rotating frame is pushed. After the rotating frame is pushed, the rotary wheel at the other end of the rotating frame meshes with the rotating shaft. Since the rotary wheel meshes with the drive shaft, the rotation direction of the rotary wheel is opposite to that of the drive shaft. When the rotary wheel meshes with the rotating shaft, the rotary wheel drives the rotating shaft to rotate in the reverse direction, so that the rotating shaft is separated from the processing point of the material. After separation, under the action of the reset mechanism, the drive shaft meshes with the rotating shaft again for transmission. In this way, the effect of simulating manual tapping is achieved. When encountering materials with high hardness, the flipping frequency increases, and when encountering materials with low hardness, the rotational force of the drive shaft can be smoothly transmitted to the rotating shaft, and the rotating shaft rotates normally. At this time, there is no need to retract the drill bit to reduce the resistance of the next drill bit entry. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. In the description of the present invention, it should be understood that the orientation or positional relationships indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. are based on the orientation or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0018] As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 shown, a multi-hole drilling and tapping integrated machine includes: Machine base 1; the main body of the device, used for carrying each component; Rotating shaft 2, rotatably installed on the machine base 1, used to transmit the rotational force of the motor to the drill bit 31; Rotating frame 41, rotatably installed on the machine base 1, used to install the connection structure between the motor and the rotating shaft 2; Transmission shaft 42, rotatably installed on the rotating frame 41, one end meshed with the output end of the motor, and the other end in transmission connection with the rotating shaft 2; Rotary wheel 43, rotatably installed on the rotating frame 41, meshed and driven with the transmission shaft 42, and in transmission connection with the rotating shaft 2 after the rotating frame 41 rotates; A reset mechanism is installed between the rotating frame 41 and the machine base 1 and is used to keep the transmission shaft 42 in transmission connection with the rotating shaft 2. A delay mechanism is installed on the machine base 1 and is used to extend the separation time when the transmission shaft 42 and the rotating shaft 2 rotate and separate, so as to ensure that the rotating wheel 43 has enough time to drive the rotating shaft 2. The drill table 3 is detachably installed on the machine base 1, and a transmission hole for transmission connection with the rotating shaft 2 is arranged thereon. The rotating frame 41 is arc-shaped, and the two ends of the arc are respectively installed with a transmission shaft 42 and a rotating wheel 43 that mesh with each other. The middle part of the rotating frame 41 is rotatably connected to the machine base 1, and the reset mechanism is arranged on the side where the rotating frame 41 is connected to the rotating shaft 2.

[0019] When this product is in use, the drill table 3 is installed as needed. After the drill table 3 is installed, the material can be processed. This product outputs a constant number of revolutions through the motor to perform drilling and tapping operations on the material. When drilling, since metal chips are continuously cut, the resistance received during drilling will be in a dynamic balance. When the drill head of the drill passes through the material, the tapping cone in the middle of the drill bit 31 contacts the material. At this time, since the tapping cone uses extrusion to generate threads on the material, a huge friction will be generated between the tapping cone and the material. At this time, due to the increase in the frictional force between the tapping cone and the material, the resistance received by the rotating shaft 2 during rotation will increase. When the resistance between the tapping cone and the material is so large that the separation force transmitted from the transmission shaft 42 to the rotating shaft 2 in the direction away from the rotating shaft 2 is greater than the force pulling the rotating frame 41 by the reset mechanism, the reset mechanism cannot hold the rotating frame 41, causing the rotating frame 41 to be pushed, so that one end of the arc-shaped rotating frame 41 tilts up, and the other end is pushed towards the rotating shaft 2 by the thrust, so that the rotating wheel 43 meshes with the rotating shaft 2, thereby pushing the rotating shaft 2 to reverse. And since the tapping cone needs to extrude the material to form threads when advancing, but when retreating, it no longer needs to extrude the material, so the force it needs is smaller, making the tapping cone retreat smoothly. And in order to increase the retreat distance so that the lubricating oil can better penetrate into the material hole, this product is designed with a delay mechanism. By delaying the rebound time of the rotating frame 41, it can make the transmission time between the rotating wheel 43 and the rotating shaft 2 last longer, so as to better transmit the power to the rotating shaft 2 and achieve the effect of driving the tapping cone to retreat.

[0020] In this embodiment, the reset mechanism includes a tension spring fixed to the rotating frame 41 and an adjusting bolt 62 threadedly connected to the machine base 1. One end of the adjusting bolt 62 passing through the machine base 1 is fixedly connected to the tension spring through a rotating ring. The stretching degree of the tension spring is adjusted by using the adjusting bolt 62, so as to use the pulling force of the tension spring to keep the transmission shaft 42 in a state of being in contact with the rotating shaft 2. And it is convenient and fast to adjust by rotating the adjusting bolt 62. Only the material type needs to be adjusted, and no adjustment is required according to the thickness, which greatly improves the versatility.

[0021] In this embodiment, the delay mechanism includes an energy storage component and a latch 56. The latch 56 can be inserted into the rotating frame 41 under the thrust of the energy storage component to further rotate the rotating frame 41. A jack 44 is provided on the rotating frame 41. The jack 44 is inclined and can be in contact with the latch 56 for transmission. The energy storage component includes an energy storage wheel 51 meshed with the rotating shaft 2, an air pump 52 coaxial with the energy storage wheel 51 and in one-way transmission, and a sliding cylinder for the latch 56 to slide. The air pump 52 and the sliding cylinder are connected through an air storage cavity. A discharge pipe 57 is provided on the sliding cylinder. A discharge hole is opened on the discharge pipe 57. A discharge air bolt 58 that can move to overlap and seal with the discharge hole is threadedly connected inside the discharge pipe 57. By using the meshing of the energy storage wheel 51 and the rotating shaft 2, the rotating shaft 2 transmits the rotational force to the energy storage wheel 51, and then the energy storage wheel 51 drives the air pump 52 to rotate. The air pump 52 pumps air into the sliding cylinder. At this time, since the rotating frame 41 does not rotate, the latch 56 abuts against the surface of the rotating frame 41. And because the air pump 52 rotates continuously, air is continuously pumped into the sliding cavity 53 for storage. The discharge hole opened on the discharge pipe 57 can slowly discharge the air. And by providing a discharge valve 55 on one side of the discharge pipe 57, when the stored pressure is too high and the discharge hole cannot discharge in time, the pressure can be quickly reduced through the discharge valve 55, thus avoiding damage caused by excessive pressure in the sliding cavity 53. When the rotating frame 41 rotates, when the rotating frame 41 rotates to a position where the latch 56 can be inserted into the jack 44, at this time, due to the air pressure in the sliding cavity 53, the latch 56 further quickly pushes the rotating frame 41 to separate from the rotating shaft 2, so that the rotary wheel 43 can contact the rotating shaft 2 faster, thereby realizing the tool retraction action. And because of the discharge hole on the rotating shaft 2 and the one-way transmission effect of the rotational force between the energy storage wheel 51 and the air pump 52, when the rotating shaft 2 rotates in the reverse direction, the energy storage wheel 51 no longer transmits the rotational force to the air pump 52. At this time, the air pump 52 no longer pumps air, and the air in the sliding cavity 53 gradually decreases under the discharge of the discharge hole. Since the force of the spring 61 on the reset device remains unchanged and the pressure that the sliding cavity 53 can provide decreases, the abutting force between the latch 56 and the jack 44 decreases, enabling the reset mechanism to pull the rotating frame 41 to rotate. When the pressure inside the sliding cavity 53 is not sufficient to support the rotating frame 41, the rotating frame 41 resets to make the transmission shaft 42 mesh with the rotating shaft 2. At this time, one feed and retraction action is completed. And due to the effect of the thread, no external force in the vertical direction is required for both retraction and feed at this time, thus realizing automatic feed and retraction. Until after tapping is completed, the operator manually retracts the tool to separate the drill and tap bit 31 from the material.

[0022] Among them, the air pump 52 in the energy storage component can also be replaced with a piston pump 54 or a pneumatic motor.

[0023] The drill table 3 includes a housing, a drill bit 31 movably located inside the housing, and a synchronous chain 32 located inside the housing in series with the drill bit 31. Since the position of each drilling and tapping changes with the position of the material, the drill table 3 of this product uses the synchronous chain 32 to link the rotation of the drill bit 31 inside the drill table 3, and then limits the drill bit 31 through the modular drill bit clamp 33. At the same time, the drill bit clamp 33 is used to change the position of the driven drill bit 31, so that the drill bit 31 can slide to any position of the drill table 3 for fixation. Such a design enables the rotating shaft 2 to penetrate into the inside of the drill table 3 along the transmission hole and mesh with the trapezoidal synchronous chain 32, and then drive the synchronous chain 32 to move. When the synchronous chain 32 moves, it will push the drill bit 31 meshing with the synchronous chain 32, thus achieving the effect of synchronous rotation of all drill bits 31, and realizing the adaptation of the drill bit 31 to the material by the characteristic that the drill bit clamp 33 can drive the drill bit 31 to move.
