Description

Technical Field

[0001] The present invention relates to the technical field of drilling machines, in particular to a drilling machine mechanism for metal processing. Background Art

[0002] A drilling machine refers to a machine tool that mainly uses a drill to process holes on a workpiece. Usually, the rotation of the drill bit is the main motion, and the axial movement of the drill bit is the feed motion. The drilling machine has a simple structure and relatively low processing accuracy. It can drill through holes and blind holes. By replacing special tools, it can expand, countersink, ream holes or perform tapping and other processing. During the processing, the workpiece does not move, and the tool moves to align the center of the tool with the center of the hole, and the tool rotates (main motion). The characteristic of a drilling machine is that the workpiece is fixed and the tool rotates;

[0003] However, when drilling holes in metal, workers need to fix the metal, adjust the drilling and spraying positions, and start the process. However, when drilling holes, the drill bit needs to rotate at a high speed to complete the drilling task. Therefore, the drill bit has a strong centrifugal force, and debris and water stains will be splashed outward under the action of the centrifugal force. If no protection is provided, the debris or water stains will splash onto the surface of the equipment, causing the equipment to short-circuit or rust.

[0004] Moreover, the existing drill bit is often exposed when not in use, and is easily invaded by external dust. When the drilling equipment is used subsequently, the hole drilled by the drill bit may deviate due to the adhesion of dust or debris. In view of this, we propose a drilling machine mechanism for metal processing. Summary of the invention

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1.

[0029] The following will be combined with the accompanying drawings in the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] For examples, please refer to Figure 1-Figure 9 A drilling machine mechanism for metal processing includes a control panel 1, a clamping device 2 for clamping metal is detachably installed on the top of the control panel 1, a drilling structure 300 for drilling holes is arranged on the side of the control panel 1, a fixing plate 4 is arranged on the side of the drilling structure 300, a surface of the fixing plate 4 is provided with a splash-proof cleaning dust shielding structure 500, and a friction structure 600 for limiting metal is arranged on the side of the cleaning dust shielding structure 500;

[0031] When in use, the cleaning dust shielding structure 500 is opened to fit the metal, and the friction structure 600 is driven to increase the friction on the metal surface. When not in use, the cleaning dust shielding structure 500 is combined to protect the drilling structure 300 and collect the debris drilled by the drilling structure 300.

[0032] As for the overall working process of the drilling structure 300, it is well known to those skilled in the art. The spindle rotates to drive the drill bit to perform rotary cutting, and the feed mechanism is used to make the drill bit perform linear feed along the axial direction. During the processing, the workpiece is fixed, the tool moves and the tool center is aligned with the hole center, and the tool rotates to perform the main motion, so that the drilling structure 300 can complete the drilling task for the metal;

[0033] The present invention takes into account that the drill bit will generate centrifugal force during the drilling process (centrifugal force: when an object moves along a circular track, it will be affected by a centripetal force pointing to the center of the circle. This force enables the object to maintain circular motion rather than linear motion, and the inertia of the object itself manifests itself as a tendency to continue linear motion, which visually or feels like a "force" trying to pull the object away from the center of the circle, the so-called "centrifugal force"), so that debris and water stains will be driven by the centrifugal force to splash outward onto the surface of the equipment, causing the equipment to short-circuit or rust. Therefore, when the drilling structure 300 generates debris during the drilling process, it will splash outward according to the centrifugal force, and the cleaning dust shield structure 500 can swing open to wipe the metal surface and protect the splashing debris, so that the debris is blocked by the cleaning dust shield structure 500 and the range of debris splashing is reduced, which is beneficial to increase the service life of the drilling equipment 303, reduce the damage to the drilling equipment 303 caused by the splashing debris, and improve the overall safety of the drilling structure 300.

[0034] In addition, the existing drill bit is often exposed when not in use, and is easily invaded by external dust. When the drilling device 303 is used later, the hole drilled by the drill bit may deviate due to the adhesion of dust or debris. Therefore, when the drilling structure 300 is not in use, the cleaning dust shielding structure 500 can reset and swing to collect the debris after drilling protection, and can wrap and protect the drilling hole that does not use the drilling structure 300, so that the drilling hole is not invaded by external dust or debris, which is beneficial to improve the subsequent drilling effect of the drilling structure 300, reduce the deviation caused by the adhesion of dust or debris, and increase the service life of the drilling structure 300.

[0035] On the basis of the above, the specific structure is disclosed in detail:

[0036] First of all, to realize the metal drilling, the following specific structure needs to be disclosed in detail, please refer to Figure 1-Figure 2 The drilling structure 300 includes a lifting platform 301 fixedly connected to the surface of the control console 1, a liquid storage tank 302 fixedly connected to the top of the lifting platform 301, a drilling device 303 fixedly connected to the top of the liquid storage tank 302, and a clamping plate is provided on the surface of the clamping device 2 detachably mounted on the surface of the control console 1;

[0037] As for the working principle of the clamping device 2, by manually rotating the crank on the clamping device 2, the clamping plates on the clamping device 2 move closer to each other, thereby completing the metal clamping task;

[0038] In order to wipe the metal surface before drilling, the following specific structure needs to be disclosed in detail, please refer to Figure 1-Figure 6 The cleaning dust shielding structure 500 includes a movable shaft 501, which is movably connected to the drilling device 303. A first baffle 502 is fixedly connected to the side of the movable shaft 501 away from the drilling device 303, and a second baffle 503 is fixedly connected to the side of the first baffle 502 away from the movable shaft 501. A cleaning brush 504 is fixedly connected to the bottom of the second baffle 503. The cleaning brush 504 is a metal soft-bristle brush, and the cleaning brush 504 is arranged in an arc shape. On the one hand, the hardness of the cleaning brush 504 can block the extrusion force when the cleaning brush 504 contacts the metal, and it is not easily damaged. On the other hand, the arc of the cleaning brush 504 is set to drive the cleaning brushes 504 to swing away from each other under the action of the extrusion force.

[0039] Please refer to Figure 1-Figure 5 When the drilling structure 300 is fed linearly as a whole, the cleaning dust shielding structure 500 is fed synchronously. After the cleaning dust shielding structure 500 is in contact with the metal as a whole, the cleaning brush 504 will first contact the metal, so that the two groups of cleaning brushes 504 swing away from each other around the movable shaft 501, so that the cleaning brushes 504 are constantly in contact with the metal surface, so as to wipe the metal and facilitate the subsequent drilling of the drill bit;

[0040] In order to facilitate the protection of the drilling structure 300 from splashing debris during drilling, the following specific structure needs to be disclosed in detail. Figure 1-Figure 6 , both sides of the second baffle 503 are fixedly connected with semicircular plates 505, and the side of the semicircular plate 505 is slidably connected to the limit plate 506, the first baffle 502 set on the top of the second baffle 503 is a conical setting, and the movable shaft 501 set on the top of the first baffle 502 is a cylindrical setting. As for the conical setting of the first baffle 502 and the cylindrical setting of the movable shaft 501, on the one hand, it is to provide a wider range of protection for the debris generated by the drilling equipment 303 when drilling, and on the other hand, it is to reduce the impact force of the splashing of the debris and increase the service life of the first baffle 502 and the movable shaft 501;

[0041] The two groups of cleaning brushes 504 swing away from each other to drive the two groups of second baffles 503 to swing, so that the second baffles 503 and the first baffles 502 swing synchronously around the movable shaft 501. At this time, the two groups of second baffles 503 swing away from each other to drive the two groups of semicircular plates 505 to swing, and the limiting plates 506 can limit the semicircular plates 505 during the swing, so that the distance between the two groups of second baffles 503 is increased, which is convenient for the subsequent protection of the drilling structure 300 from splashing debris;

[0042] In order to achieve the protection of the drilling structure 300 from the debris splashing during drilling, the following specific structure needs to be disclosed in detail, please refer to Figure 1-Figure 6 Two groups of semicircular plates 505 are arranged on both sides of the movable shaft 501. The holes opened inside the second baffle plate 503 are adapted to the water pipe 507. The second baffle plate 503 is provided with holes adapted to the water pipe 507. The water pipe 507 and the liquid storage tank 302 are fixedly connected through. The liquid storage tank 302 and the drilling equipment 303 are detachably installed. The detachable installation of the liquid storage tank 302 is to better replace the water in the liquid storage tank 302.

[0043] By swinging the second baffles 503 away from each other, the drill bit in the drilling device 303 will be exposed to contact the metal and drill. At this time, the staff can operate the control console 1 to control the liquid storage tank 302 to discharge water into the water pipe 507, and spray it to the drilling position of the drill bit of the drilling device 303, so as to reduce dust floating and reduce the high temperature generated by the friction of the metal surface. At the same time, the debris drilled by the drilling device 303 will splash outward according to the centrifugal force generated by the drill bit. At this time, the second baffle 503 and the semicircular plate 505 after swinging open can protect the splashing debris and water stains, prevent the drilling structure 300 from being damaged by debris and water stains, and improve the overall service life of the drilling structure 300.

[0044] In order to prevent vibration during metal drilling, the following specific structure needs to be disclosed in detail, please refer to Figure 7-Figure 9The friction structure 600 includes an arc rod 601 and a linear slide 605. The arc rod 601 is fixedly connected to the side of the semicircular plate 505. The linear slide 605 is opened inside the fixed plate 4. The top of the arc rod 601 is fixedly connected to the movable plate 602. The movable plate 602 is internally connected to a limited axis 604 for rotation. The bottom of the movable plate 602 is fixedly connected to a wave block 603. The limited axis 604 is fixedly connected to the inside of the linear slide 605. The limited axis 604 and the linear slide 605 are adapted to each other.

[0045] The arc rod 601, the movable plate 602, the wave block 603 and the limit shaft 604 are symmetrically arranged in two groups along the transverse center of the fixed plate 4. The arc rod 601 is arranged in an arc shape, the movable plate 602 is arranged in an L shape, and the wave block 603 is arranged in a wave shape. After the swinging is completed, it will adhere to the metal surface to increase the friction and reduce the jitter caused by the metal drilling.

[0046] When the two groups of semicircular plates 505 swing away from each other, the two groups of arc rods 601 swing away from each other, and synchronously drive the movable plate 602 and the wave block 603 to swing around the center of the limit axis 604. At the same time, the wave block 603 swings against the metal surface, which not only realizes the left and right limit fixation of the metal by the clamping device 2, but also increases the friction force on the metal surface, improves the metal limit fixation effect, prevents the jitter caused by the drill bit drilling, and is conducive to improving the clamping effect of the metal;

[0047] In order to realize the cleaning of the dust shielding structure 500 and the protection of dust shielding when the drilling structure 300 is not used, the following specific structure needs to be disclosed in detail, please refer to Figure 1-Figure 6 , two groups of movable shafts 501, first baffles 502, second baffles 503 and cleaning brushes 504 are symmetrically arranged along the center of the drilling device 303, and the two groups of second baffles 503 are arranged in a semicircular shape. As for the cleaning dust shielding structure 500, two groups are arranged, on the one hand, to protect the debris splashed by the drilling device 303, and on the other hand, to prevent the invasion of external dust when the drilling device 303 is not in use, which is beneficial to improve the service life of the drilling device 303;

[0048] After the drilling structure 300 has completed drilling and the cleaning dust shielding structure 500 has completed blocking, when the drilling structure 300 is no longer in use, the operator needs to control the control console 1 to reset the drilling structure 300 and the cleaning dust shielding structure 500, and the second baffle 503 will not contact the metal and will lose the pressure. The two sets of second baffles 503 will be close to each other and reset, swing and merge, so that the second baffle 503, the first baffle 502 and the movable shaft 501 will reset, swing and merge. At the same time, the two sets of second baffles 503 will reset, swing and merge. When the two sets of second baffles 503 are completely reset and merged, the drill bit in the drilling equipment 303 can be wrapped and protected to prevent external dust and debris from sticking to the brick surface when the drill bit of the drilling equipment 303 is not in use, which is beneficial to improving the subsequent drilling effect of the drill bit.

[0049] Working principle: The worker places the metal on the surface of the clamping device 2, and then manually adjusts the position of the clamping plate set on the surface of the clamping device 2 to complete the clamping of the metal. Then, the worker controls the lifting platform 301 through the control console 1 to adjust the positions of the liquid storage tank 302 and the drilling device 303, and drives the drill bit in the drilling device 303 to rotate at a high speed and the liquid in the liquid storage tank 302 to flow out from the water pipe 507;

[0050] When adjusting the overall position of the drilling device 303, the cleaning dust shield structure 500 will also follow the adjustment position, and then the cleaning brush 504 will first contact the metal, so that the two groups of cleaning brushes 504 will swing away from each other around the movable shaft 501, and synchronously drive the two groups of second baffles 503 to swing. At this time, the two groups of second baffles 503 swing away from each other, driving the two groups of semicircular plates 505 to swing, and causing the limit plates 506 in the two groups of semicircular plates 505 to move down the limit, and increasing the distance between the two groups of second baffles 503. At the same time, the drill bit in the drilling device 303 is exposed to contact the metal and drill. At the same time, the debris drilled by the drilling device 303 will splash outward according to the centrifugal force generated by the drill bit. At this time, the second baffle 503 and the semicircular plate 505 that have been swung open can protect against splashing debris and water stains.

[0051] When the drilling structure 300 is not in use, the staff needs to control the control console 1 to reset the drilling structure 300 and feed it, and simultaneously reset the cleaning dust shielding structure 500 and feed it. At this time, the second baffle 503 will not contact the metal and will lose the resistance force. The two groups of second baffles 503 will approach each other to reset, swing and merge, so that the second baffle 503, the first baffle 502 and the movable shaft 501 reset, swing and merge. At the same time, the bottom of the reset, swung and merged cleaning brush 504 will contact the metal and wipe the metal after cleaning the drilling, and the reset, swing and merge of the second baffle 503 can clamp and collect the debris remaining on the metal surface. At the same time, after the two groups of second baffles 503 are completely reset and merged, the drill bit in the drilling equipment 303 can be wrapped and protected. When used again, the debris in the second baffle 503 needs to be removed by the staff.

[0052] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the present invention and are not intended to limit the present invention.
