Description

Technical Field

[0001] The invention relates to the technical field of drilling equipment, in particular to a casing drilling equipment for producing computer casings. Background Art

[0002] Computers are widely used in various fields in modern society. As an important component, their casings need to meet multiple functional requirements, such as dustproof, waterproof, anti-static, shockproof and heat dissipation. This puts higher demands on drilling equipment to ensure the quality and performance of the casing. Some ordinary drilling devices are difficult to move to the processing position accurately when drilling holes in different positions of the computer casing, affecting the processing efficiency and accuracy. For example, some existing equipment cannot perform multi-position and multi-angle drilling processing on the computer casing. Computer casings are mostly thin-shell products, and burrs are easily generated on the hole wall after drilling. Although some existing equipment can drill and grind, the grinding equipment and drilling are operated separately, the switching time is long, and the inner wall of the casing cannot be polished, resulting in burrs remaining on the inner wall, which is easy to scratch the hands.

[0003] Current drilling equipment is prone to processing errors due to the vibration of the drill bit itself and poor fixation of the shell during drilling. Traditional methods often use an overall fixation method, which lacks fixation of the drilling position. Summary of the Invention

[0014] The present invention provides a casing drilling device for computer casing production and manufacturing. It has the following beneficial effects:

[0015] 1. The casing drilling equipment for manufacturing computer casings is provided with a first motor. The driving shaft of the first motor drives a rotating plate to rotate. The rotation of the rotating plate drives a sliding rod to move along an arc-shaped chute, so that the sliding rod approaches or moves away from the rotation center of the first motor, thereby driving a first sliding strip to slide along the inner wall of a linear chute, and then driving a fixed bottom plate to slide along the inner wall of the linear chute. When the casing is placed, the fixed bottom plate drives an auxiliary bracket to move. The movement of the auxiliary bracket drives a telescopic rod bracket to move. The movement of the telescopic rod bracket drives a first spring rod to move. The movement of the first spring rod drives an arc-shaped fixing plate to move, thereby driving a rubber strip to move, so that the bottom of the rubber strip contacts the top of the casing, thereby fixing the top of the casing. Moreover, the cooperation between the telescopic rod bracket and the auxiliary bracket enables the telescopic rod bracket to rotate at a certain angle, so as to adapt to casings with different edge shapes, thereby fixing different casings, fixing casings with different shapes, and performing the fixation simultaneously in multiple directions, so that the force is evenly distributed, avoiding the deformation of the casing caused by uneven force or the movement of the casing caused by uneven force.

[0016] 2. The casing drilling equipment for manufacturing computer casings is provided with a drilling motor. The rotation of the driving shaft of the drilling motor drives a first rotating cylinder to rotate. The rotation of the first rotating cylinder drives a first toothed ring to rotate. The rotation of the first toothed ring drives a gear shaft to rotate. The rotation of the gear shaft drives a second toothed ring to rotate. The rotation of the second toothed ring drives a connecting plate to rotate. The rotation of the first rotating cylinder drives a blowing assembly to rotate, thereby generating a downward air flow to blow the drilling position, so as to timely clean the drilling debris. Through the commutation of a commutation gear, the rotation directions of the first rotating cylinder and the second toothed ring are opposite, thereby offsetting the vibration influence brought by the torque of the driving shaft of the drilling motor, so that the center of the drill bit remains stable, reducing the machining error caused by vibration, and thus improving the drilling accuracy.

[0017] 3. The casing drilling equipment for manufacturing computer casings is provided with a first rotating cylinder. When the first rotating cylinder rotates, it drives the hollow fan blades to rotate. The rotation of the hollow fan blades drives the adjustment slider to slide on the inner wall of the hollow fan blades. The first spring drives the adjustment slider to approach the rotation center. During rotation, the centrifugal force causes the counterweight to drive the adjustment slider away from the rotation center. The faster the rotation speed, the greater the centrifugal force, resulting in different moments of inertia generated by the counterweight. Thus, different moments of inertia are generated according to different rotation speeds, and the vibration influence brought by the drive shaft of the drilling motor is offset according to different rotation speeds. Moreover, when the hollow fan blades rotate, the angle of the hollow fan blades drives the air to flow, driving the air to spray downward onto the surface of the drilled hole, thereby timely cleaning the debris generated by the drilling, ensuring the processing quality. And during the process of the counterweight moving away from the rotation center, the adjustment slider stretches the first spring, generating a pulling force. When the rotation speeds are different, the pulling force of the first spring is different, resulting in different degrees of stretching, and correspondingly generating different moments of inertia, thus achieving the purpose of adaptively adjusting the moment of inertia, offsetting the vibration influence brought by the torque at different rotation speeds, maintaining a stable state during drilling, and improving the processing accuracy. When replacing the drill bit, manually twist the fixed end of the second spring rod. The twisting of the second spring rod drives the drive rod to slide along the inner wall of the limit slide hole, driving the movable end of the second spring rod to slide. The contraction of the movable end of the second spring rod drives the side surface away from the side surface of the drill bit, releasing the drill bit, facilitating the replacement of the drill bit. After the new drill bit is installed, manually twist the fixed end of the second spring rod to release the drive rod. Then, under the action of the spring inside the second spring rod, the drill bit positioning block is pushed to closely adhere to the side surface of the drill bit, fixing the drill bit. During drilling, the torque acts on the side surface of the limit block. The limit block is fixed to the inner wall of the fixed casing, driving the drill bit to rotate for drilling operations. And the rubber pad prevents the drive rod from sliding after the drill bit is installed, maintaining the fixed state of the drill bit.

[0018] 4. The casing drilling equipment for manufacturing computer casings is provided with a bearing descending. The descending of the bearing drives the first bracket to descend. The descending of the first bracket drives the grinding frame to descend. The grinding frame drives the cylindrical grinding block to descend. During the descending of the bearing, the third spring rod is compressed. The elastic force provided by the third spring rod drives the grinding frame to descend. The descending of the grinding frame drives the cylindrical grinding block to polish the edge of the hole to eliminate burrs and improve the processing quality. And the cylindrical grinding block is fixed around the punched hole, fixing the periphery of the punched hole during punching, maintaining a stable state of the punching position, thus reducing the influence of vibration and other errors on the punching accuracy. Moreover, during the ascending of the drilling motor, the third spring rod drives the grinding frame to adhere to the surface of the casing for fixing and grinding. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] Place the casing on the top of the fixing plate 505. Start the first motor 502. The driving shaft of the first motor 502 drives the rotating plate 503 to rotate. The rotation of the rotating plate 503 drives the sliding rod 5083 to move along the arc-shaped sliding groove 504, so that the sliding rod 5083 approaches or moves away from the rotation center of the first motor 502. Thus, the sliding rod 5083 drives the first sliding bar 5082 to slide along the inner wall of the linear sliding groove 506, thereby driving the fixing base plate 5081 to slide along the inner wall of the linear sliding groove 506. After the casing is placed, the fixing base plate 5081 drives the auxiliary bracket 5084 to move. The movement of the auxiliary bracket 5084 drives the telescopic rod bracket 5085 to move. The movement of the telescopic rod bracket 5085 drives the first spring rod 5086 to move. The movement of the first spring rod 5086 drives the arc-shaped fixing plate 5087 to move, thereby driving the rubber strip 5088 to move, so that the bottom of the rubber strip 5088 contacts the top of the casing, thereby fixing the top of the casing. Moreover, the cooperation between the telescopic rod bracket 5085 and the auxiliary bracket 5084 enables the telescopic rod bracket 5085 to rotate at a certain angle, so as to adapt to casings with different edge shapes, thereby fixing different casings, fixing casings with different shapes, and performing the fixing synchronously in multiple directions, so as to make the force uniform and avoid the deformation of the casing caused by uneven force or the movement of the casing caused by uneven force.

[0034] Please refer to Figures 1 - 5, the present invention provides a technical solution: the drilling device 7 includes a drilling motor 701, the bottom of the drilling motor 701 is fixedly connected to a motor bracket 702, a shock absorption device 703 is fixedly connected to the drive shaft of the drilling motor 701, a blowing component 704 is fixedly connected to the side of the shock absorption device 703, a quick-release component 705 is fixedly connected to the bottom of the shock absorption device 703, a positioning component 706 is fixedly connected to the side of the quick-release component 705, and the top of the motor bracket 702 is fixedly connected to the side of the movable end of the electric lifter 6.

[0035] The shock absorption device 703 includes a first rotating cylinder 7031, a first toothed ring 7032 is fixedly connected to the bottom of the first rotating cylinder 7031, a fixed shaft 7033 is rotatably connected to the inner wall of the first rotating cylinder 7031, a gear shaft 7034 is fixedly connected to the side of the fixed shaft 7033, a reversing gear 7035 is sleeved and rotatably connected to the side of the gear shaft 7034, a second toothed ring 7036 is sleeved and rotatably connected to the bottom of the fixed shaft 7033, the bottom of the second toothed ring 7036 is fixedly connected to the top of the quick-release component 705, the top of the reversing gear 7035 meshes with the bottom of the first toothed ring 7032, the bottom of the reversing gear 7Q35 meshes with the top of the second toothed ring 7036, and the side of the first rotating cylinder 7031 is fixedly connected to the side of the blowing component 704.

[0036] When the drilling motor 701 is started, the drive shaft of the drilling motor 701 rotates to drive the first rotating cylinder 7031 to rotate. The first rotating cylinder 7031 rotates to drive the first toothed ring 7032 to rotate. The first toothed ring 7032 rotates to drive the gear shaft 7034 to rotate. The gear shaft 7034 rotates to drive the second toothed ring 7036 to rotate. The second toothed ring 7036 rotates to drive the connecting plate 7037 to rotate. The first rotating cylinder 7031 rotates to drive the blowing component 704 to rotate, thereby generating a downward pressing air flow to blow the drilling position, so as to timely clean the drilling debris. Through the reversing of the reversing gear 7035, the rotation directions of the first rotating cylinder 7031 and the second toothed ring 7036 are opposite, so as to offset the vibration influence brought by the torque of the drive shaft of the drilling motor 701, so that the center of the drill bit remains stable, reduce the processing error caused by vibration, and thus improve the drilling accuracy.

[0037] Please refer to Figures 1 - 7, the present invention provides a technical solution: the blowing component 704 includes a hollow fan blade 7041, a spring groove 7042 is formed in the inner wall of the hollow fan blade 7041, a first spring 7043 is fixedly connected to the side surface of the spring groove 7042, one end of the first spring 7043 away from the hollow fan blade 7041 is fixedly connected to an adjustment slider 7044, one end of the adjustment slider 7044 away from the first spring 7043 is fixedly connected to a counterweight 7045, and the side surface of the hollow fan blade 7041 is fixedly connected to the side surface of the first rotating cylinder 7031.

[0038] The quick-release component 705 includes a fixed housing 7051, the fixed end of a second spring rod 7052 is rotatably connected to the side surface of the fixed housing 7051, an auxiliary rod 7053 is fixedly connected to the side surface of the second spring rod 7052, a limiting slide hole 7054 is formed in the side surface of the fixed end of the second spring rod 7052, a driving rod 7055 is fixedly connected to the side surface of the movable end of the second spring rod 7052, the driving rod 7055 extends into the inner wall of the limiting slide hole 7054 and is slidably connected to the inner wall of the limiting slide hole 7054, a rubber pad 7056 is fixedly connected to the inner wall of the limiting slide hole 7054, a fixed sliding ring 7057 is fixedly connected to the side surface of the fixed end of the second spring rod 7052, the fixed end of the second spring rod 7052 is rotatably connected to the side surface of the fixed housing 7051 through the fixed sliding ring 7057, a drill bit positioning block 7058 is fixedly connected to the side surface of the second spring rod 7052, a limiting block 7059 is fixedly connected to the inner wall of the fixed housing 7051, an opening adapted to the drill bit positioning block 7058 is formed in the side surface of the limiting block 7059, the top of the fixed housing 7051 is fixedly connected to the bottom of the connecting plate 7037, and the side surface of the fixed housing 7051 is fixedly connected to the inner wall of the positioning component 706.

[0039] When the first rotating cylinder 7031 rotates, the rotation of the first rotating cylinder 7031 drives the hollow fan blade 7041 to rotate. The rotation of the hollow fan blade 7041 drives the adjustment slider 7044 to slide on the inner wall of the hollow fan blade 7041. The first spring 7043 drives the adjustment slider 7044 to approach the rotation center. When rotating, the existence of centrifugal force causes the counterweight 7045 to drive the adjustment slider 7044 away from the rotation center. The faster the rotation speed, the greater the centrifugal force, so that the moment of inertia generated by the counterweight 7045 is different. Thus, different moments of inertia are generated according to different rotation speeds, and the vibration influence brought by the drive shaft of the drilling motor 701 is offset according to different rotation speeds. Moreover, when the hollow fan blade 7041 rotates, the angle of the hollow fan blade 7041 drives the air to flow, so as to drive the air to spray downward on the surface of the drill hole, so as to clean the debris generated by the drill hole in time, thus ensuring the processing quality. And in the process of the counterweight 7045 moving away from the rotation center, the adjustment slider 7044 stretches the first spring 7043, thus generating a pulling force. When the rotation speeds are different, the pulling force of the first spring 7043 is different, so as to be stretched to different degrees, and thus different moments of inertia are correspondingly generated, so as to achieve the purpose of adaptively adjusting the moment of inertia, offset the vibration influence brought by the torque at different rotation speeds, so as to keep the state stable during drilling, thus improving the processing accuracy. When replacing the drill bit, manually twist the fixed end of the second spring rod 7052. The twisting of the second spring rod 7052 drives the drive rod 7055 to slide along the inner wall of the limit slide hole 7054, so as to drive the movable end of the second spring rod 7052 to slide. The contraction of the movable end of the second spring rod 7052 drives the side of the drill bit positioning block 7058 to leave the side of the drill bit, so as to release the drill bit, thus facilitating the replacement of the drill bit. When the new drill bit is installed, manually twist the fixed end of the second spring rod 7052 to release the drive rod 7055, so as to push the drill bit positioning block 7058 to closely adhere to the side of the drill bit under the action of the spring inside the second spring rod 7052, so as to fix the drill bit. The torque during drilling acts on the side of the limit block 7059. The limit block 7059 is fixed to the inner wall of the fixed housing 7051, so as to drive the drill bit to rotate, thus performing the drilling operation. And the setting of the rubber pad 7056 prevents the drive rod 7055 from sliding after the drill bit is installed, so as to keep the fixed state of the drill bit.
