Description

Technical Field

[0001] The invention relates to the technical field of drilling equipment, in particular to a drilling machine with a dust removal device. Background Art

[0002] A drilling machine is a common mechanical equipment, which is mainly used for drilling operations on different materials. The drilling machine has been widely used in the manufacturing industry. In the roller brush production process, a drilling machine is required for drilling processing.

[0003] When drilling, the high-speed rotation of the drill bit often produces chips and dust that threaten the health of operators and the working environment. Large amounts of dust diffuse in the work area, which not only increases the difficulty of cleaning, but may also cause respiratory diseases and other health problems. In addition, the chips and dust produced during the drilling process will also affect the normal operation of mechanical equipment and reduce the service life of the drilling machine; Moreover, the dust accumulated in the hole during drilling may cause the drill bit to rub against the dust during rotation, increase the wear of the drill bit, and even cause the drill bit to become clogged. This will reduce the drilling efficiency and may cause damage to the drill bit. The accumulated dust and chips will cause the drill bit to deviate, affecting the accuracy of the hole diameter. If the dust accumulates in the hole, the drill bit may not be able to accurately align with the center of the hole, resulting in an irregular hole diameter, affecting the quality of the product. When drilling, the dust accumulated on the hole wall will affect the smoothness of the drilling process, resulting in an uneven surface of the hole wall, which in turn affects the subsequent processing or assembly process; therefore, we propose a drilling machine with a dust removal device to solve this problem.

[0025] In this embodiment, the workpiece to be drilled is placed above the base 1 so that the position to be drilled is aligned with the drill bit 7, and then the first electric push rod 302 and the second electric push rod 403 are started. The first electric push rod 302 drives the two side pressure plates 3 to approach each other to achieve lateral clamping of the workpiece, and the second electric push rod 403 drives the lower pressure plate 4 to move downward to clamp the top of the workpiece. The clamping force of the workpiece is monitored by the first pressure sensor 301 and the second pressure sensor 402.

The driving motor 13 drives the driving gear 14 to rotate, and the driving gear 14 drives the hollow shaft 702 and the drill bit 7 to rotate by meshing with the first driven gear 703. The servo motor 503 drives the screw rod 502 to rotate, and the screw rod 502 rotates by engaging with the slide frame The threaded cooperation of 501 drives the sliding frame 501 to move downward, and the sliding frame 501 drives the large gear 506 and the small gear 507 to move downward through the mounting frame 505. The rack 504 drives the large gear 506 to rotate by meshing with the large gear 506. The large gear 506 drives the small gear 507 to accelerate its rotation by meshing with the small gear 507. The small gear 507 drives the rotating arm 508 to rotate synchronously. The rotating arm 508 drives the connecting column 509 to perform a circular motion. The connecting column 509 drives the side plate 601 to reciprocate up and down relative to the sliding frame 501 by cooperating with the slide plate 511 and the connecting frame 510. Since the sliding frame 501 keeps moving downward during this process, the lifting plate 6 moves upward after moving downward for a distance, and drives the drill bit 7 to move synchronously. After moving downward, the drill bit 7 enters the workpiece to drill a hole, and then the drill bit 7 moves upward to throw out the waste chips generated by the drilling, and so on and so forth, thereby avoiding the accumulation of waste chips inside the drilling hole to cause speed and affect the drilling quality.

[0026] By starting the vacuum pump 809, the air in the dust box 806 is extracted and introduced into the refrigerator 810, thereby generating negative pressure at the suction nozzle 801, extracting the waste chips and dust generated by drilling, and entering the dust box 806 through the annular tube 804, the horizontal tube 802, the lower curved tube 803 and the upper curved tube 805, filtering the dust and waste chips through the arc filter 808, and collecting them through the dust box 807. After entering the refrigerator 810, the air is cooled by the refrigerator 810, introduced into the hollow shaft 702 through the air outlet nozzle 811, and then enters the cavity of the drill bit 7, and is ejected from multiple spiral exhaust ports to take out the heat inside the drill bit 7 and blow out the waste chips generated by drilling, further avoiding the accumulation of waste chips. The meshing of the driving gear 14 and the second driven bevel gear drives the linkage shaft 902 and the rotating frame 903 to rotate, and drives the sleeve plate 904 The connecting frame 905 performs circular motion with the connecting frame 905. The connecting frame 905 obtains an outward centrifugal force under the action of the centrifugal force, and drives the linkage disk 907 to rotate and move upward at the same time through the sliding cooperation with the trapezoidal plate 906. The linkage disk 907 drives the pressure plate 908 to move upward and squeezes the varistor 911 and the compression spring 910. After the varistor 911 is squeezed, the resistance of the varistor 911 decreases, and the greater the speed of the driving gear 14, the greater the squeezing force on the varistor 911 and the smaller the resistance. Since the vacuum pump 809 and the refrigerator 810 are connected in series with the varistor 911, the power of the vacuum pump 809 and the refrigerator 810 is increased, thereby increasing the vacuum speed and the cooling speed, so as to increase the cooling speed of the drill bit 7 and the dust absorption effect, thereby meeting the use requirements of the drilling machine at different speeds, so as to facilitate the drilling of workpieces of different materials and shapes.
