Description

Technical Field

[0001] The utility model relates to the technical field of milling machines, in particular to a numerically controlled gantry milling machine. Background Art

[0002] CNC gantry milling machines are mainly composed of a gantry, a milling table and an electrical control system. Compared with ordinary milling machines, gantry milling machines are generally larger in size and are especially suitable for processing large parts.

[0003] Like ordinary milling machines, CNC gantry milling machines generate a large amount of metal chips during the machining process. These chips need to be cleaned up after machining to avoid affecting the subsequent processing and placement of parts. Most of the CNC gantry milling machines currently in common use do not have the function of automatically cleaning metal chips. Most of them require manual use with an air dust removal gun to blow away the metal chips. Due to the large length and width of the milling table of the CNC gantry milling machine, the staff not only need to blow away the metal chips on the surface of the wide milling table, but also need to blow away the metal chips in the multiple longitudinal fixed grooves on the milling table. The cleaning process is relatively labor-intensive, time-consuming and labor-intensive, which is not conducive to efficient production. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the utility model provides a CNC gantry milling machine, which is used to solve the problem that the currently commonly used CNC gantry milling machines do not have the function of automatically cleaning metal chips, resulting in a large workload of manual cleaning and a waste of time and effort.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0006] A CNC gantry milling machine comprises a milling machine table, the upper surface of the milling machine table being provided with longitudinal fixed grooves equidistantly arranged in the transverse direction, fixed longitudinal rails being provided on both sides of the milling machine table, a gantry mounted on the milling machine table being longitudinally connected to the fixed longitudinal rails by transmission, a lifting transverse rail being installed on the front of the gantry, a milling machine head being transversely connected to the lifting transverse rail by transmission, a milling cutter being installed at the bottom of the milling machine head, a turntable being rotatably mounted on one side of the back of the gantry, and a rotary drive mechanism being installed on the back of the gantry by transmission connection to the turntable;

[0007] A rigid diversion straight pipe is installed on the turntable, and a positioning support mechanism is provided on the back side of the gantry away from the turntable, which is located at the same height as the turntable and is movably connected to the diversion straight pipe. A nozzle inclined downward toward the front is fixedly connected to the diversion straight pipe at a position corresponding to the milling machine workbench, and a connecting hose connected to an air compressor or a booster water pump is installed at one end of the diversion straight pipe.

[0008] Preferably, the rotary drive mechanism includes a worm gear rotatably mounted on the back of the gantry and fixedly connected to the turntable, a worm mounted on the back of the gantry and meshing with the worm gear, and a servo motor mounted on the back of the gantry and connected to the worm gear, and the diversion straight pipe is located on the back of the worm gear and the servo motor.

[0009] Preferably, the positioning support mechanism includes a fixed platform vertically fixedly installed on the back of the gantry, and a card slot and an installation slot are longitudinally arranged on the fixed platform, the card slot corresponds to the position of the diversion straight pipe, and the installation slot is located on the front of the card slot, and a positioning hole is longitudinally arranged at a position above the diversion straight pipe on the fixed platform, a positioning pin located above the diversion straight pipe is movably inserted in the positioning hole, and a push rod transmission-connected to the positioning pin is fixedly installed in the installation slot.

[0010] Preferably, the distance between the lower end of the nozzle and the upper surface of the milling machine table is no more than 10 cm.

[0011] Preferably, the nozzles are arranged at equal intervals along the diversion straight pipe, and a nozzle is provided above each longitudinal fixed groove.

[0012] Preferably, the connecting hose is connected to an electromagnetic three-way valve, and two inlets of the electromagnetic three-way valve are respectively connected to an air compressor and a booster water pump.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The utility model installs a rotatable diversion straight pipe at the rear of the gantry. When the diversion straight pipe rotates horizontally, the nozzle on the diversion straight pipe can simultaneously blow away metal chips from the entire milling machine worktable and multiple longitudinal fixed grooves during the movement of the gantry along the fixed longitudinal rail. After the metal chips are cleaned, the diversion straight pipe rotates upward and moves away from the milling machine worktable, which does not affect the normal milling cutter operation and replaces manual cleaning, saving time and effort, and is efficient and fast. It solves the problem that the currently commonly used CNC gantry milling machines do not have the function of automatically cleaning metal chips, resulting in a large workload, time and effort in manual cleaning.

[0015] 2. The diversion straight pipe is connected to the air compressor and the booster water pump through a connecting hose and an electromagnetic three-way valve, so it can switch between water spraying and air blowing. It can be used to clean metal chips by blowing air, by spraying water, and by cleaning the milling machine workbench by spraying water, achieving a multifunctional effect.

[0024] A turntable 6 is rotatably mounted on one side of the back of the gantry 3. A rotary drive mechanism 7 connected to the turntable 6 is mounted on the back of the gantry 3. A rigid diversion straight pipe 8 is mounted on the turntable 6. The rotary drive mechanism 7 drives the turntable 6 and the diversion straight pipe 8 to rotate to clean the metal chips. The diversion straight pipe 8 rotates to a horizontal position. After the cleaning is completed, the diversion straight pipe 8 rotates to a vertical position.

[0025] The rotary drive mechanism 7 includes a worm gear 701 rotatably mounted on the back of the gantry 3 and fixedly connected to the turntable 6, a worm 702 mounted on the back of the gantry 3 and meshing with the worm gear 701 for transmission, and a servo motor 703 mounted on the back of the gantry 3 and connected to the worm 702 for transmission. The diverter pipe 8 is located on the back of the worm 702 and the servo motor 703.

[0026] A positioning support mechanism 9 is provided on the side of the back of the gantry 3 facing away from the turntable 6, which is located at the same height as the turntable 6 and is movably connected to the shunt straight pipe 8. The positioning support mechanism 9 includes a fixed platform 901 vertically fixedly installed on the back of the gantry 3. A clamping groove 902 and a mounting groove 903 are longitudinally provided on the fixed platform 901. The clamping groove 902 corresponds to the position of the shunt straight pipe 8. The mounting groove 903 is located on the front of the clamping groove 902. A positioning socket 904 is longitudinally provided on the fixed platform 901 at a position above the shunt straight pipe 8. A positioning pin 905 located above the shunt straight pipe 8 is movably inserted into the positioning socket 904.

[0028] Working principle:

[0029] The initial state of the diversion straight pipe 8 is vertical, not above the milling machine table 1, so as to avoid obstruction of the milling cutter 501 in processing parts. When metal chips need to be cleaned, after the parts are removed after processing, the servo motor 703 of the rotary drive mechanism 7 drives the diversion straight pipe 8 to rotate downward through the worm 702, the worm gear 701 and the turntable 6 to snap into the slot 902 of the positioning support mechanism 9, and the push rod 906 drives the positioning pin 905 to insert into the positioning socket 904, thereby supporting and fixing the movable end of the diversion straight pipe 8;

[0030] The electromagnetic three-way valve 12 connects to the air compressor or the booster water pump according to a predetermined plan, and sprays high-pressure air or high-pressure water onto the surface of the milling machine table 1 and the interior of the longitudinal fixed groove 101 through the nozzle 10 on the diversion straight pipe 8. The gantry 3 moves along the fixed longitudinal rail 2, thereby completing the cleaning of the entire surface of the milling machine table 1 and the interior of the longitudinal fixed groove 101.

[0031] After the cleaning is completed, the push rod 906 drives the positioning pin 905 to retract, and the rotary drive mechanism 7 drives the diversion straight pipe 8 to rotate upward through the turntable 6 to restore the initial position.
