Description
Technical Field
[0001] This invention relates to the field of drilling machine technology, specifically to an automatic drilling machine. Background Technology
[0002] Drilling machines are commonly used automated processing equipment in fields such as machining, road inspection, and workpiece processing. They mainly use a motor to drive the drill bit to rotate and drill holes in various workpieces, plates, and road substrates. During the drilling process, the high-speed friction between the drill bit and the workpiece generates a lot of heat, which can easily cause problems such as drill bit wear, scorching of the workpiece at the drilling position, and deviation in hole position accuracy. Therefore, the industry generally uses coolant spraying to cool and lubricate the drill bit and the processing area to ensure the drilling quality and the service life of the equipment.
[0003] Currently, the coolant spray structure design of automatic drilling machines on the market is relatively simple, mostly using fixed nozzles for direct spraying cooling. This has many drawbacks in actual use. The coolant nozzles are mostly independent fixed structures, and during long-term operation, they are prone to displacement due to equipment vibration and external force, causing the coolant to be inaccurately aimed at the drill bit's processing area. Furthermore, existing spray structures lack effective coolant collection and diversion structures. When the coolant supply pressure is low, the coolant spray range and flow rate are unstable, easily leading to coolant dripping and incomplete spraying. Residual coolant in the nozzles cannot be recycled, resulting in low resource utilization. In addition, during the drill bit's downward drilling process, there is a lack of a corresponding protective collection structure, making it impossible to effectively avoid coolant splashing. This creates a poor processing environment, and splashed coolant may also affect the normal operation of surrounding detection and transmission components. Therefore, we propose an automatic drilling machine. Summary of the Invention

[0014] Compared with the prior art, the present invention provides an automatic drilling machine, which has the following beneficial effects: 1. In this automatic drilling machine, a protective ring is first pressed on the workpiece during the drilling process. The protective ring can collect the coolant, prevent the coolant from spilling, and reduce the splashing of coolant. As the motor moves down, the first rotating rod and the second rotating rod will rotate relative to each other, and drive the spring to deform. The spring can facilitate the rotation of the first rotating rod and the second rotating rod.
[0015] 2. This automatic drilling machine utilizes a chuck to hold the coolant nozzle in place, preventing it from shifting position and allowing it to directly align with the drill bit, reducing the need for adjusting the nozzle's position. Then, the electric actuator is activated, adjusting the chuck's tilt angle to ensure precise spraying of coolant onto the drill bit. Moving the protective sleeve rotates the second connecting shaft, which in turn rotates the second bevel gear. The first bevel gear then rotates the first connecting shaft, which in turn rotates the worm gear, causing the sliding shaft to slide within the groove. This adjusts the position and angle of the guide plate. A pad supports the guide plate, allowing coolant to be directed into the inner side of the protective ring even under low water pressure. Residual coolant dripping from the nozzle is also directed into the inner side of the protective ring.
[0016] 3. This automatic drilling machine can press down the rotating shell to press down the sliding cylinder using the pressure plate, and at the same time the clamping block separates from the clamping slot. At this time, rotating the rotating shell can adjust the position of the connecting shell, ensuring that the coolant nozzle can always be aligned with the drill bit after adjusting the position of the coolant nozzle, thus ensuring the coolant spraying effect.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
[0020] Please see Figure 1 - Figure 12An automatic drilling machine includes a drilling machine body 1 and a slide 2 slidably connected to the upper end of the drilling machine body 1. A motor 3 is provided at the front end of the slide 2, and a drill bit 4 is provided at the lower end of the motor 3. A protective component 5 for collecting coolant is provided on the outside of the motor 3. The protective component 5 includes a protective ring 51 provided on the outside of the drill bit 4. A water guiding component 6 is provided on the outside of the protective ring 51. The water guiding component 6 includes a rotating component 61 provided on the outside of the protective ring 51. The water guiding component 6 also includes a connecting shell 62. A positioning component 64 and a flow guiding component 63 are provided on the inner side of the connecting shell 62. The positioning component 64 includes a retainer 643. A coolant nozzle 7 is engaged on the inner side of the retainer 643.
[0021] It should be noted that the coolant nozzle 7 in this invention is externally connected to a coolant delivery pipe and a pressurizing device. These devices are not within the scope of protection of this invention, therefore this invention does not describe the coolant delivery pipe and the pressurizing device.
[0022] In this embodiment, a first connecting seat 52 is fixedly connected to both sides of the motor 3. A first rotating rod 53 is rotatably connected to the inner side of the first connecting seat 52. A second rotating rod 54 is rotatably connected to the lower end of the first rotating rod 53. Two sets of second connecting seats 55 are fixedly connected to the outer side of the protective ring 51. The two sets of second connecting seats 55 are rotatably connected to the two sets of second rotating rods 54 respectively.
[0023] Specifically, during the drilling process, the motor 3 will drive the protective component 5 to move downward, so that the protective ring 51 will first press on the workpiece. The protective ring 51 can collect the coolant and prevent the coolant from spilling. As the motor 3 moves downward, the first rotating rod 53 and the second rotating rod 54 will rotate relative to each other.
[0024] In this embodiment, a fixed housing 56 is fixedly connected to the rear end of the first rotating rod 53, a rotating shaft 57 is rotatably connected to the inner side of the fixed housing 56, a spring piece 58 is provided on the outer side of the rotating shaft 57, the spring piece 58 is located on the inner side of the fixed housing 56, and the first rotating rod 53 and the second rotating rod 54 are rotatably connected through the rotating shaft 57.
[0025] Specifically, the rotation of the first rotating rod 53 and the second rotating rod 54 can cause the spring piece 58 to deform, and the spring piece 58 can facilitate the rotation of the first rotating rod 53 and the second rotating rod 54.
[0026] In this embodiment, the rotating assembly 61 includes a rotating shell 611 rotatably connected to the outside of the protective ring 51, a connecting shell 62 fixedly connected to the rotating shell 611, the connecting shell 62 tilting downwards, a ring 612 fixedly connected to the outside of the protective ring 51, the ring 612 being located inside the rotating shell 611, a slot 613 being provided at the lower end of the ring 612, a locking block 614 fixedly connected to the inside of the rotating shell 611, the slot 613 and the locking block 614 engaging, a plurality of connecting parts 616 being provided at the upper end of the ring 612, a pressure plate 615 being fixedly connected to the upper end of the plurality of connecting parts 616, and the pressure plate 615 being slidably connected to the protective ring 51.
[0027] Specifically, pressing down on the rotating shell 611 can use the pressure plate 615 to press down the slide cylinder 6161, while the locking block 614 separates from the locking slot 613. At this time, rotating the rotating shell 611 can adjust the position of the connecting shell 62.
[0028] In this embodiment, the connector 616 includes a sliding post 6163 fixedly connected to the ring 612. A sliding cylinder 6161 is slidably connected to the outer side of the sliding post 6163. A spring 6162 is provided on the inner side of the sliding post 6163. The spring 6162 is fixedly connected to the sliding post 6163.
[0029] Specifically, the spring 6162 can push the slide 6161 upward, causing the rotating shell 611 to move upward, so that the locking block 614 can re-engage into the inside of the locking slot 613, thus fixing the rotating shell 611 and ensuring the stability of the connecting shell 62.
[0030] In this embodiment, the drainage component 63 includes a drainage plate 631 slidably connected to the inner side of the connecting shell 62. The connecting shell 62 has grooves 632 on both sides. The drainage plate 631 is rotatably connected to the two sides of the sliding shaft 633. The two sets of sliding shafts 633 are slidably connected to the inner side of the two sets of sliding grooves 632 respectively. A pad 6313 is fixedly connected to the inner side of the connecting shell 62. The pad 6313 is inclined downward.
[0031] Specifically, the sliding shaft 633 slides inside the sliding groove 632, thereby adjusting the position and angle of the diverter plate 631. The pad plate 6313 can support the diverter plate 631. The diverter plate 631 can introduce coolant into the inner side of the protective ring 51 when the water pressure is low. It can also introduce the residual coolant dripping from the coolant nozzle 7 into the inner side of the protective ring 51, ensuring the utilization efficiency of the coolant.
[0032] In this embodiment, two sets of first fixing blocks 635 are fixedly connected to both sides of the connecting shell 62, and a first connecting shaft 636 is rotatably connected between the two sets of first fixing blocks 635. A worm gear 637 is provided on the outer side of the first connecting shaft 636, and a worm wheel 634 is fixedly connected to one end of the sliding shaft 633. The worm wheel 634 meshes with the worm gear 637.
[0033] Two sets of second fixing blocks 639 are fixedly connected to the lower end of the connecting shell 62. A second connecting shaft 6310 is rotatably connected between the two sets of second fixing blocks 639. A second bevel gear 6312 is fixedly connected to both ends of the second connecting shaft 6310. A first bevel gear 638 is fixedly connected to one end of the first connecting shaft 636. The second bevel gear 6312 meshes with the first bevel gear 638. A protective sleeve 6311 is provided on the outer side of the second connecting shaft 6310.
[0034] Specifically, the protective sleeve 6311 is turned to drive the second connecting shaft 6310 to rotate, which in turn drives the second bevel gear 6312 to rotate. The first bevel gear 638 drives the first connecting shaft 636 to rotate, which in turn drives the worm gear 637 to rotate the worm wheel 634, making it convenient to adjust the position of the diverter plate 631.
[0035] Preferably, the positioning component 64 includes a top post 641 fixedly connected to the inner side of the connecting shell 62, a ball 642 rotatably connected to the upper end of the top post 641, the ball 642 being fixedly connected to the retaining shell 643, an electric push rod 644 fixedly connected to the outer side of the top post 641, two sets of third fixing blocks 645 fixedly connected to the lower end of the retaining shell 643, and the upper end of the electric push rod 644 being rotatably connected between the two sets of third fixing blocks 645.
[0036] Specifically, the chuck 643 can hold the coolant nozzle 7 in place, preventing the coolant nozzle 7 from shifting position and allowing the coolant nozzle 7 to be directly aligned with the drill bit 4, reducing the steps required to adjust the position of the coolant nozzle 7. The electric actuator 644 can be used to adjust the tilt angle of the chuck 643 and adjust the height of the coolant sprayed from the coolant nozzle 7.
[0037] It should be noted that during use, the coolant nozzle 7 is secured inside the retaining housing 643. Then, the electric actuator 644 is activated to adjust the tilt angle of the retaining housing 643, ensuring that the coolant sprayed from the coolant nozzle 7 is precisely applied to the drill bit 4. The rotation of the retaining housing 643 is facilitated by the ball bearing 642 rotating on the top post 641. Moving the protective sleeve 6311 rotates the second connecting shaft 6310, which in turn rotates the second bevel gear 6312. The first bevel gear 638 then rotates the first connecting shaft 636, which in turn rotates the worm gear 637, causing the worm wheel 634 to rotate. This allows the sliding shaft 633 to slide inside the groove 632, thereby adjusting the position and angle of the guide plate 631. The pad 6313 provides support for the guide plate 631. The coolant can be introduced into the inner side of the protective ring 51 under low water pressure by the diversion plate 631. The residual coolant dripping from the coolant nozzle 7 can also be introduced into the inner side of the protective ring 51. Pressing down on the rotating shell 611 can press down the slide cylinder 6161 using the pressure plate 615. At the same time, the locking block 614 separates from the locking slot 613. At this time, rotating the rotating shell 611 can adjust the position of the connecting shell 62. During the drilling process, the motor 3 will drive the protective component 5 to move down, so that the protective ring 51 will first press on the workpiece. The protective ring 51 can collect the coolant and prevent the coolant from spilling. As the motor 3 moves down, the first rotating rod 53 and the second rotating rod 54 will rotate relative to each other and drive the spring plate 58 to deform. The spring plate 58 can facilitate the rotation of the first rotating rod 53 and the second rotating rod 54.
[0038] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
