The embodiment of the application provides a vertical drilling machine. The vertical drilling machine can be used for processing holes on the surface of a workpiece. The workpiece may be, for example, a metal part, a plastic part, or the like. The holes can be round holes, square holes, blind holes, through holes, threaded holes and the like.
Referring to fig. 1, fig. 1 is a schematic structural view of a vertical drill rig 10 of the prior art.
The vertical drill 10 includes a base 100, a table 200, a first column 300, a second column 400, and a headstock 500.
The base 100 is used to mount the vertical drill 10, for example, to mount the vertical drill 10 in a process shop. The chassis 100 may be a metal chassis, or the chassis 100 may be made of metal and plastic.
The table 200 is mounted on the base 100. The table 200 is used for placing a workpiece (a workpiece to be processed). For example, the table 200 may be provided with a clamping mechanism. The clamping mechanism is used for clamping the workpiece and preventing the workpiece from moving in the machining process.
Wherein the working platform 200 can move on the base 100, and the specific working platform 200 can move on the base 100 along the longitudinal direction. Thus, the longitudinal position of the workpiece relative to the drill bit can be adjusted by movement of the table 200 so that the vertical drill 10 can machine different longitudinal positions of the workpiece. For example, a slide rail may be provided on the base 100, and the table 202 may slide on the base 100 along the slide rail.
The surface of the worktable 200 may be horizontal, so that the workpiece may be horizontally placed on the worktable 200, which is beneficial to the processing of the workpiece.
The first shaft 300 is mounted on the base 100. For example, the first shaft 300 may be installed at one end of the base 100. The first upright 300 is used to support the upper structure of the vertical drill 10, for example, the second upright 400 and the headstock 500. First shaft 300 may be a metal shaft, or first shaft 300 may be made of metal and plastic.
Wherein second upright 400 is movable on first upright 300, and particularly second upright 400 is movable in a transverse direction on first upright 300. Thus, the lateral position of the workpiece with respect to the drill bit can be adjusted by the movement of the second upright 400, so that the vertical drill 10 can machine different lateral positions of the workpiece. For example, a slide rail may be provided on first shaft 300, and second shaft 400 may slide on first shaft 300 along the slide rail.
In some embodiments, first shaft 300 has first driving device 310 mounted thereon, and first driving device 310 includes a moving portion and a fixed portion. The moving part of first driving device 310 is mounted on second upright 400, the fixed part of first driving device 310 is mounted on first upright 300, and when first driving device 310 is operated, the moving part of first driving device 310 moves relative to the fixed part of first driving device 310, so that second upright 400 is driven to move on first upright 300. Alternatively, the first driving device 310 may be a hydraulic cylinder, a linear motor, or the like.
A second driving means 410 is installed on the second upright 400, and the second driving means 410 includes a moving part and a fixed part. The moving part of the second driving means 410 is mounted on the headstock 500, the fixed part of the second driving means 410 is mounted on the second column 400, and when the second driving means 410 is operated, the moving part of the second driving means 410 moves relative to the fixed part of the second driving means 410, so that the headstock 500 is driven to move on the second column 400. Alternatively, the second driving device 410 may be a hydraulic cylinder, a linear motor, or the like.
The headstock 500 includes a main shaft 510 and a third driving device 540, the upper end of the main shaft 510 is connected to the third driving device 540, and the third driving device 540 is used for driving the main shaft 510 to rotate, so as to drive a drill bit arranged on the main shaft 510 to perform a drilling operation. Alternatively, the third driving device 540 may be a motor, and power transmission between the motor and the main shaft 510 may be realized by a belt transmission, a gear transmission, or the like.
The lower end of the main shaft 510 is provided with a lock cutter seat 520, and the lock cutter seat 520 is provided with a gun drill 530. After the moving table 200 and the second upright 400 adjust the drilling position of the gun drill 530 relative to the workpiece, the second driving device 410 and the third driving device 540 work to drive the main shaft 510 to move linearly along the axis and/or rotate around the axis, so as to drive the gun drill 530 to move downwards and rotate, thereby performing the drilling operation on the workpiece.
The gun drill is an effective deep hole processing cutter, has a wide processing range, and can process deep holes from plastics such as die steel, glass fiber, Teflon and the like to high-strength alloy. The gun drill is classified into an integral type and a welding type according to the diameter of the gun drill and the conditions of inner cooling holes of a driving part, a shank part and a cutter head. The cooling liquid is sprayed out from the small hole on the back cutter surface. The gun drill may have one or two circular cooling holes, or a single kidney-shaped hole. Since the bit of the gun drill is made of cemented carbide, it can withstand much higher cutting speeds than a high-speed steel drill, which increases the feed per minute of the gun drill. In addition, when high-pressure cooling liquid is used, the chips can be effectively discharged from the machined hole, and the chips do not need to be discharged by withdrawing the cutter regularly in the drilling process.
However, when the drilling machine performs drilling operation, high-pressure cutting fluid is ejected from the inner hole of the gun drill 530, the iron chips are ejected upwards from the chip discharge groove of the tool by rebounding from the bottom of the hole of the workpiece, and are scattered irregularly in various directions after colliding against the tool locking seat 520, and the main shaft 510 rotates at a high speed, so that the cutting fluid is scattered more quickly, a large amount of oil mist or water mist is formed in the process, the mist is difficult to recover, and not only is a large amount of volatile consumption of the cutting fluid caused, but also environmental pollution is caused.
