Description

Technical Field

[0001] The present invention relates to the technical field of automatic drilling machines, and particularly to an efficient and stable automatic drilling machine. Background Art

[0002] Existing automatic drilling machines generally perform operations such as drilling, flaring, and threading by means of a double-group drill bit mechanism cooperating with a linkage tray when processing diverse workpieces. The following technical problems also exist in the operation and processing process: 1. Traditional drilling machines mostly use independent motors to drive the bilateral drill bits. Not only is the structure complex and the energy consumption high, but it is also difficult to achieve rapid switching between single-sided / double-sided processing, resulting in frequent adjustment of equipment when processing single-sided drilling, double-sided synchronous drilling, or reaming / tapping composite processes, with low efficiency; 2. When the drilling machine is processing on one side, the drill bit on the non-working side often accidentally moves due to mis-triggering or program failure and collides with the workpiece or fixture. The existing mechanical limit devices also need to cooperate with the program for unlocking and locking operations, and there is still a slow response in case of program failure; For this reason, we propose an efficient and stable automatic drilling machine.

[0005] Furthermore, the inner cavity is opened inside the workbench. On the two side walls of the inner cavity, chutes are symmetrically opened. The chutes correspond to the inner side positions of the movable frames. The two groups of mating racks are arranged in an alternating manner and are engaged with the corresponding mating gears.

[0007] Furthermore, slides are fixedly mounted on the sides of the two groups of mating gear rods, and the slides are slidably mounted inside the slide slots and fixedly connected to the inner side of the movable frame, and a first protective plate is symmetrically fixedly connected between the side of the slide and the wall of the slide slot.

[0008] Furthermore, the main frame is arranged on the upper side of the workbench and is rotatably installed on the upper side of the workbench through a circular ring block. A matching cavity is opened on the upper side of the workbench, and the linkage rod is movably installed inside the matching cavity and the linkage rod is fixedly installed on the upper side of the trigger block.

[0009] Furthermore, the battery block is fixedly arranged at the inner center position of the main frame, the clamping module is movably arranged on the inner side of the main frame in a mirror image, a workpiece block is arranged on the side of the clamping module, the second electric push rod is fixedly installed on the inner bottom side of the main frame in a mirror image and the output end of the second electric push rod is fixedly connected to the side position of the clamping module, and a second protective plate is fixedly connected between the clamping module and the side of the battery block.

[0010] Furthermore, the two groups of movable cavities are opened on the wall of the matching cavity and the two groups of movable cavities are arranged in a mirror-like manner, the protective rod partially extends out of the internal position of the movable cavity, the support tube is fixedly connected between the side of the protective rod and the wall of the support tube and the support tube is movably sleeved on the side of the protective rod.

[0011] Furthermore, the detection block is fixedly mounted on the wall of the movable cavity close to the matching cavity, the buffer spring is fixedly mounted on the side of the detection block and the other end of the buffer spring is fitted to the side of the protective rod, the side of the linkage rod is fixedly sleeved with a matching tube, the side of the matching cavity is provided with an air intake groove that passes through the workbench, the side of the matching cavity is provided with a connecting groove, and the spray rack passes through the slide.

[0012] Compared with the prior art, the present invention can achieve the following beneficial effects: 1. The present invention can realize multi-state driving operation with energy saving effect by setting a driving mechanism and a safety mechanism. At the same time, when the movable frame on one side moves in the multi-state driving, it can be linked to trigger the protective rod on the other side to be pushed out by the high-pressure gas, so as to perform buffering protection operation on the drill bit at the other end to avoid collision between the drill bit and the workpiece.

[0013] 2. By providing a driving mechanism in the present invention, and by arranging a touch block and an elastic fitting block structure that can move axially inside the fitting rod, the corresponding fitting gear can be selectively triggered to be driven. Only one motor needs to be provided to trigger the driving of each component, and by replacing the types of drills, rapid switching among processes such as drilling, reaming, and tapping can be achieved (such as from State 1 to State 4 in the specification). Compared with traditional double motors, it can save more energy, and the transmission components are integrated inside the workbench cavity, so the structure is compact and the occupied space of the drill press can be reduced.

[0014] 3. By providing a safety mechanism in the present invention, when the unilateral movable frame is driven to move, the safety mechanism pushes out the protective rod on the non-working side through high-pressure gas, and its buffer rubber block forms an elastic damping barrier with the movable frame; if abnormal movement occurs, the protective rod cooperates with the support cylinder for the first-stage buffering, and then the protective rod slides into the movable cavity and presses against the side of the buffer spring for secondary buffering. When the buffer spring is compressed, the pressure of the detection block rapidly increases, and the generated signal can trigger the emergency stop mechanism.

[0015] 4. By providing a driving mechanism and a clamping mechanism in the present invention, when the touch block slides out of the inside of the fitting rod, the linkage rod fits under the main frame. While the motor drives the fitting rod to rotate, the linkage rod can drive the main frame to rotate 180 degrees. With the second electric push rod driving the mirror-arranged clamping modules to move synchronously, workpieces of different diameters and lengths can be detected, and after the workpiece rotates, the second electric push rod is used to finely adjust and compensate for the position deviation, which can ensure the coaxiality of the workpiece during multi-process machining.

[0016] 5. By providing a linkage rod, a spraying frame and other components around it in the present invention, the switching of the high-pressure gas passage can be controlled by the displacement of the linkage rod: during processing, the sealing ring blocks the connection groove to avoid air flow interference; when the workpiece is at the rotating station, the gas automatically switches to the spraying frame to blow the chute directionally, and together with the first protective plate with a W-shaped cross-section, an iron chip diversion channel is formed, which can prevent the iron chips inside the chute from falling into the inner cavity and affecting the meshing and movement of the fitting gear, the fitting tooth rod and the sliding frame.

A drilling module 12 is fixedly arranged on the side of the active frame 11. The drilling module 12 is composed of a driving motor and a drill bit. The drill bit can be replaced according to requirements (such as twist drill bits, flat drills, and flaring drills, etc.). A driving mechanism 2 capable of multi-state driving is arranged on the bottom side of the workbench 1, and most of the structure of the driving mechanism 2 penetrates through the internal position of the workbench 1.

Slide grooves 22 that penetrate the workbench 1 are symmetrically opened on the two side walls of the inner cavity 21, and the slide grooves 22 correspond to the inner side of the movable frame 11. The slide grooves 22 are rectangular grooves. Two groups of matching gears 23 are symmetrically arranged at the inner center position of the inner cavity 21. The matching gears 23 are annular gears.

The matching gear rods 24 are "L"-shaped gear rods. Slide racks 241 are fixedly installed on the sides of the two groups of matching gear rods 24, and the slide racks 241 are slidably installed in the slide grooves 22 and fixedly connected to the inner side of the movable frame 11.

The first protective plate 242 is a rectangular plate with a continuous "W"-shaped cross-section. The first protective plate 242 can protect the slide 22 to prevent iron filings from falling into the slide 22 and the inner cavity 21. A motor 25 is fixedly installed at the position corresponding to the matching gear 23 on the lower side of the workbench 1, and a matching rod 26 is fixedly installed at the output end of the motor 25. The matching rod 26 passes through the workbench 1 and extends to the internal position of the two sets of matching gears 23. The matching rod 26 is a hollow cylindrical rod with an open upper end. A first electric push rod 261 is fixedly installed on the inner bottom side of the matching rod 26, and a trigger is fixedly installed at the output end of the first electric push rod 261 The block 262 is a cylindrical block with tapers on both sides. The side of the mating rod 26 is equidistantly provided with movable grooves 263 in a circular array corresponding to the positions of the two groups of mating gears 23. The movable grooves 263 penetrate the mating rod 26 to the inner side thereof. The movable grooves 263 are convex grooves. A mating block 264 is movably installed inside the movable groove 263. The mating block 264 is a convex rubber block with an arc on one side. In the default state, the arc surface of the mating block 264 extends out of the movable groove 263 to the inner side of the mating rod 26. The mating block 264 does not fit the inner side of the mating gear 23. A support block 264 is symmetrically fixedly connected between the side of the mating block 264 and the wall of the movable groove 263. The support block 265 is movably arranged in the inner position of the movable groove 263, and the support block 265 is a corrugated sheet made of spring steel; specifically, the first electric push rod 261 can push and pull the touch block 262 to move the position, and the touch block 262 can selectively trigger the matching gears 23 at different positions; when the touch block 262 corresponds to the position of the two groups of matching gears 23, the touch block 262 squeezes all the matching blocks 264 to slide and fit in the inner position of the matching gear 23 in the movable groove 263, and at this time, the motor 25 drives the matching rod 26 to rotate, and the matching rod 26 can drive the two groups of matching gears 23 to rotate and mesh with the corresponding matching gear rod 24, and pull the slide 241 to slide in the slide groove 22 through the matching gear rod 24 to drive the two groups of movable frames 11 to move;When the trigger block 262 corresponds to the position of a set of mating gears 23, at this time, the trigger block 262 only presses the side of the corresponding mating block 264. The motor 25 drives the mating rod 26 to rotate, and the mating rod 26 can drive the corresponding set of mating gears 23 to rotate and mesh with the mating rack 24, only driving a set of movable frames 11 to perform a moving operation; The clamping mechanism 3 provided can clamp different workpieces, and can perform corresponding workpiece moving operations according to different drilling operations; Such as Figures 2 to 4 and Figure 6 、 Figure 8 、 Figure 9 As shown, the clamping mechanism 3 includes a main frame 31 arranged on the upper side of the workbench 1, and the main frame 31 is rotatably installed on the upper side of the workbench 1 through an annular block. The main frame 31 is a rectangular frame with a hollow upper side. A mating cavity 32 penetrating through it to the inside of the inner cavity 21 is opened at the position corresponding to the mating gears 23 on the upper side of the workbench 1. The mating cavity 32 is a cylindrical cavity. A linkage rod 33 is movably installed inside the mating cavity 32, and the linkage rod 33 is fixedly installed at the upper side position of the trigger block 262. The linkage rod 33 is a cylindrical rod with a cross-section in the shape of a Chinese character 'tu' and a sealing ring is arranged on its side. A battery block 34 is fixedly arranged at the center position inside the main frame 31. The battery block 34 is a rectangular battery with a charging port opened on the upper side. Clamping modules 35 are mirror-image movably arranged inside the main frame 31. The clamping modules 35 can adopt standard-type electric control grippers. A workpiece block 5 is arranged on the side of the clamping module 35. The workpiece block 5 can adopt cylinders with different diameters and lengths. Second electric push rods 36 are mirror-image fixedly installed at the bottom side inside the main frame 31, and the output ends of the second electric push rods 36 are fixedly connected to the side positions of the clamping modules 35. The second electric push rods 36 are electrically connected to the battery block 34 through contacts. A second protective plate 37 is fixedly connected between the side of the clamping module 35 and the battery block 34. The second protective plate 37 is a rectangular plate with a cross-section in the shape of a continuous 'W'; specifically, the first electric push rod 261 pushes the trigger block 262 to move upward and slide out of the mating rod 26 to the position inside the mating cavity 32. The linkage rod 33 slides inside the mating cavity 32 along with the trigger block 262 and fits against the lower side of the main frame 31. At this time, the motor 25 drives the mating rod 26 to rotate, and the two sets of mating gears 23 are not driven. The main frame 31 is driven by the linkage rod 33 to rotate on the upper side of the workbench 1; when clamping the workpiece, the battery block 34 can supply power to the clamping module 35 and the second electric push rods 36. The second electric push rods 36 push and pull the clamping modules 35 to slide inside the main frame 31. By clamping and fixing the workpiece block 5 through the clamping module 35, workpieces with different diameters and lengths can be adapted; The safety mechanism 4 provided can perform corresponding buffer safety protection on the components on the other side when the drill press performs unilateral drilling work, and can also perform a certain cleaning operation when not drilling; Such as Figures 2 to 4 and Figure 6 、Figure 9 As shown in the figure, the safety mechanism 4 includes two groups of movable cavities 41 opened on the wall surface of the mating cavity 32, and the two groups of movable cavities 41 are arranged in a mirror-image and staggered manner. The movable cavity 41 penetrates through the workbench 1 and is arranged above the sealing ring of the linkage rod 33. The movable cavity 41 is a cylindrical cavity with a cross-shaped cross-section. A protective rod 42 is movably installed inside the two groups of movable cavities 41, and a part of the protective rod 42 extends out of the inside of the movable cavity 41. The protective rod 42 is a "T"-shaped round rod with a sealing ring sleeved on its side, and a buffer rubber block is fixedly installed on its side. When the protective rod 42 extends out, the buffer rubber block on its side can contact and buffer the accidentally moved movable frame 11. A support cylinder 43 is fixedly connected between the side of the protective rod 42 and the wall surface of the support cylinder 43, and the support cylinder 43 is movably sleeved on the side of the protective rod 42. The support cylinder 43 is a corrugated cylinder made of an elastic material. A detection block 44 is fixedly installed on the wall surface of the movable cavity 41 close to the mating cavity 32. The detection block 44 can be a circular pressure sensor. A buffer spring 45 is fixedly installed on the side of the detection block 44, and the other end of the buffer spring 45 is attached to the side of the protective rod 42. A mating cylinder 46 is fixedly sleeved on the side of the linkage rod 33. By default, the mating cylinder 46 is arranged above the movable cavity 41. The mating cylinder 46 is a cylinder with fan-shaped grooves equidistantly arranged on its side. An air inlet groove 461 penetrating through the workbench 1 is opened on the side of the mating cavity 32 corresponding to the lower position of the linkage rod 33. The air inlet groove 461 can communicate with an external high-pressure cylinder. The air inlet groove 461 is located below the sealing ring of the linkage rod 33 in the default state. A connection groove 47 penetrating through the workbench 1 to the sliding groove 22 is opened on the side of the mating cavity 32. A spraying rack 48 is fixedly installed on the wall surface of the sliding groove 22 corresponding to the connection groove 47, and the spraying rack 48 penetrates through the sliding frame 241. The spraying rack 48 is a "U"-shaped rack with one-way air nozzles equidistantly arranged on its side, and its internal air flow channel is communicated with the connection groove 47; specifically, when the trigger block 262 is located on the side of the movable groove 263 at the position of the two groups of mating gears 23, the mating cylinder 46 can block the two groups of movable cavities 41. At this time, the driving mechanism 2 can drive the two groups of movable frames 11 to perform drilling operations on the drilling module 12; when the trigger block 262 is located on the side of the movable groove 263 at the position of one group of mating gears 23, the mating cylinder 46 only blocks one group of movable cavities 41, and high-pressure gas enters the other group of movable cavities 41. The gas pushes the protective rod 42 to slide inside the movable cavity 41 and squeezes the support cylinder 43 to deform. At this time, the movable frame 11 at the end where the protective rod 42 does not extend out performs drilling operations on the drilling module 12; when the trigger block 262 slides out of the inside of the mating rod 26, the main frame 31 can be driven to rotate. At this time, the air inlet groove 461 is located below the sealing ring of the linkage rod 33, and the two groups of movable cavities 41 are not connected to high-pressure gas either. Synchronously, high-pressure gas enters the spraying rack 48 from the connection groove 47, and jets through its one-way air nozzles to clean the iron filings inside the sliding groove 22.

[0021] Working principle: Before drilling: Select the corresponding working procedure according to whether to drill on one side or both sides of the workpiece block 5. Place the single workpiece block 5 or two workpiece blocks 5 on the side of the clamping module 35 manually or by a robotic arm, and clamp and fix the workpiece block 5 through the corresponding clamping module 35. During drilling: First step, as shown in State 3 in Figure 12 , at this time, the first electric push rod 261 pulls the trigger block 262 to slide to the lower position to cooperate with the inner position of the gear 23, squeezes the corresponding fitting block 264 to slide inside the movable slot 263 and fit against the inner position of the mating gear 23. The motor 25 drives the fitting rod 26 to rotate downward to engage with the mating gear 23 and the mating rack 24 to drive the left movable frame 11 of the workbench 1 to move. After the drilling module 12 drills the workpiece block 5, the motor 25 drives in the reverse direction to retract the tool. At this time, the sealing ring of the linkage rod 33 blocks the connecting groove 47, and the fitting cylinder 46 blocks the left movable cavity 41. Second step, as shown in State 1 in Figure 10 , at this time, the first electric push rod 261 pushes the trigger block 262 out of the inside of the fitting rod 26, and the linkage rod 33 fits against the lower side of the main frame 31. While the motor 25 drives the fitting rod 26 to rotate, the linkage rod 33 can drive the main frame 31 to rotate 180 degrees. The second electric push rod 36 pushes and pulls the clamping module 35 to move, and the position of the corresponding workpiece block 5 can be compensated and moved to adapt to the subsequent drilling operation. At this time, the sealing ring of the linkage rod 33 is located above the air inlet groove 461, and the two movable cavities 41 are blocked. The high-pressure gas flows from the connecting groove 47 to the one-way nozzles of the spraying rack 48 for jet cleaning. Third step, as shown in State 4 in Figure 13 , at this time, the first electric push rod 261 pulls the trigger block 262 to slide to the upper position to cooperate with the inner position of the gear 23, squeezes the corresponding fitting block 264 to slide inside the movable slot 263 and fit against the inner position of the mating gear 23. The motor 25 drives the fitting rod 26 to rotate upward to engage with the mating gear 23 and the mating rack 24 to drive the right movable frame 11 to move. After the drilling module 12 reams or threads the workpiece block 5, the motor 25 drives in the reverse direction to retract the tool. At this time, the linkage rod 33 blocks the connecting groove 47, and the fitting cylinder 46 blocks the right movable cavity 41. According to the above three working steps, the workpiece block 5 drilled on one side can be processed. Fourth step, as shown in State 2 in Figure 11 , at this time, the first electric push rod 261 pushes and pulls the trigger block 262 to the position of the two mating gears 23. The trigger block 262 squeezes all the fitting blocks 264 to slide inside the movable slot 263 and fit against the inner position of the mating gears 23. The motor 25 drives the fitting rod 26 to rotate, and the two mating gears 23 engage with the mating rack 24 to drive the two movable frames 11 to move. The two drilling modules 12 drill both sides of the workpiece block 5 simultaneously. According to the above work steps, the workpiece block 5 with holes drilled on both sides can be processed; Among the above four work steps, as Figure 12 and Figure 13 shown, at this time, only one side of the movable frame 11 is driven to move. Synchronously, the other side of the movable cavity 41 is communicated with the high-pressure gas through the air inlet groove 461. The protection rod 42 is pushed by the gas to slide out of the inner position of the movable cavity 41. When the program goes wrong or the component is damaged and causes the other side of the movable frame 11 to be driven to move, the protection rod 42 can play an elastic damping buffering role for the movable frame 11. Synchronously, after being squeezed, the protection rod 42 slides into the inner part of the movable cavity 41 and contacts the buffer spring 45 for another buffering operation. After the buffer spring 45 is stressed, the side pressure value of the detection block 44 increases rapidly, and the signal is fed back to the external controller to trigger the emergency stop mechanism, so as to avoid the collision between the drilling module 12 and the workpiece block 5 and play a safety protection role.

[0022] 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 to this. Various changes can be made without departing from the gist of the present invention within the scope of knowledge possessed by those skilled in the art to which the present invention pertains.
