Description

Technical Field

[0001] The invention relates to the technical field of milling and grinding, in particular to a gantry type multi-head milling and grinding composite machining center and an operation method thereof. Background Art

[0002] Milling and grinding generally refers to milling machines, which mainly refer to machine tools that use milling cutters to process various surfaces of workpieces. Usually, the rotation of the milling cutter is the main motion, and the movement of the workpiece and the milling cutter is the feed motion. In the prior art, when processing workpieces, the workpiece processed by the milling machine needs to be transferred to the grinder for fine grinding. During the transfer process, the workpiece may be scratched and needs to be re-clamped and calibrated, which delays working hours. Milling and grinding composite machining centers are now mostly used for processing.

[0003] Chinese Patent Publication No. CN213638450U discloses a milling and grinding compound machining center. In view of the existing need to transfer workpieces processed by a milling machine to a grinder for fine grinding, the workpiece may be damaged during the transfer process, and when it is placed on the grinder, it needs to be re-clamped and calibrated, which delays the working time. The following scheme is proposed, which includes a machining table, a rotating column is rotatably installed on the top of the machining table, a first cylinder is fixedly installed on the outer side of the rotating column, a first motor is fixedly installed on the output shaft of the first cylinder, a fixed sleeve is fixedly installed on the output shaft of the first motor, a locking bolt is threadedly installed on the fixed sleeve, a stopping mechanism is provided on the rotating column, and two L-shaped plates are fixedly installed on the top of the machining table.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. In the gantry-type multi-head milling and grinding compound machining center, the rotating gear is driven to rotate by the output shaft of the servo motor, so that the first rack provided on the side wall of the first movable plate moves downward in the vertical direction, and the second movable plate drives the servo grinding disc to move in the opposite direction.

[0035] The following will be combined with the drawings in the embodiments of 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.

[0036] One of the purposes of the present invention is to provide a gantry type multi-head milling and grinding compound machining center, referring to Figure 1-Figure 7As shown, it includes a gantry platform 100, and an electric suction cup 101 is provided on the surface of the gantry platform 100. The electric suction cup 101 is used to absorb and fix the material to be processed. A rotating motor 200 is provided on one side of the gantry platform 100. A screw rod 201 is provided on the output end of the rotating motor 200. A moving frame 202 is provided on the surface of the screw rod 201. The moving frame 202 moves horizontally above the gantry platform 100. An electric guide rail 203 is provided on the surface of the moving frame 202. A moving seat 204 is provided on the surface of the electric guide rail 203. A processing component 300 is provided at the end of the moving seat 204. The processing component 300 is used to perform milling and grinding processing on the material. A protective component 400 is provided under the mobile frame 202. The protective component 400 is used to absorb the smoke generated during the milling process when the processing component 300 performs milling and grinding alternately, and automatically blow off the processing chips remaining on the surface of the material after the milling process is completed. A reset component 500 is provided on one side of the protective component 400:

[0037] In the process of processing materials, the through slots need to be milled for the materials. After the milling is completed, the materials need to be transported to the grinder for grinding. In the process of transporting materials, the labor intensity of the operators is increased, and the processing efficiency is low. Therefore, the processing component 300 includes a base plate arranged on both sides of the end of the movable seat 204, and the first movable plate 301 and the second movable plate 302 are slidingly provided on the surface of the base plate. The surfaces of the first movable plate 301 and the second movable plate 302 are respectively provided with a servo milling cutter 303 and a servo grinding disc 304. The servo milling cutter 303 is used for milling the materials, and the servo grinding disc 304 is used for grinding the milled materials. The side walls of the first movable plate 301 and the second movable plate 302 are both provided with a first rack. A servo motor 305 is provided between the base plates, and a rotating gear 306 is provided at the output end of the servo motor 305. The two sides of the rotating gear 306 are meshed with the first rack. The rotating gear 306 rotates to drive the racks of the side walls of the first movable plate 301 and the second movable plate 302 to move away from each other. In a natural state , the first movable plate 301 and the second movable plate 302 are kept at a relatively far position. During the processing, the movable frame 202 on the surface of the screw rod 201 is moved in the horizontal direction by the rotating motor 200. At the same time, the movable seat 204 is controlled to move on the surface of the electric guide rail 203, so as to accurately process the material. The output end of the servo motor 305 drives the rotating gear 306 to rotate, so that the first movable plate 301 and the second movable plate 302 move relative to each other. When the first movable plate 301 moves downward in the vertical direction to the milling hole position, the servo milling cutter 303 on the surface of the first movable plate 301 performs milling hole processing. When the milling hole processing is completed, there is no need to transport the material to the grinding machine. It is only necessary to control the rotating motor 200 to rotate in the opposite direction. At this time, the first movable plate 301 moves upward in the vertical direction, and the second movable plate 302 drives the servo grinding disc 304 to move downward in the vertical direction. The material with the milled hole is polished by the servo grinding disc 304. The milling hole grinding of the material is automatically completed by the device, and the processing efficiency is improved.

[0038] Considering that in the process of processing the material, in the process of milling the material, a large amount of heat is generated during the drilling process due to the friction between the milling cutter and the material surface. When the heat on the surface of the metal material is too high, smoke containing metal oxides is easily generated. For example, iron oxide contained in the smoke will irritate the respiratory tract of the operator and affect health and safety. Moreover, after the milling is completed, the operator needs to blow away the chips. Therefore, the protection component 400 includes a connection box arranged under the movable frame 202, and a rotating disk 408 is rotatably provided on the surface of the connection box. A high-speed blower 409 is provided on the surface of the rotating disk 408. The connection box is remotely An adsorption box 411 is provided on one side of the high-speed blower 409, and activated carbon particles are placed inside the adsorption box 411. During the processing of the servo milling cutter 303, the blowing direction of the high-speed blower 409 is rotated to the adsorption box 411, so that negative pressure is generated near the high-speed blower 409, and the smoke generated by the processing of the servo milling cutter 303 is adsorbed into the adsorption box 411. When the processing of the servo milling cutter 303 is completed, the high-speed blower 409 is rotated to the direction of the material. An air collecting plate 410 is provided on one side of the high-speed blower 409. When the blowing direction of the high-speed blower 409 is rotated to the adsorption box 411, the air is increased by the air collecting plate 410. The negative pressure suction near the blower 409 blows the chips processed by the servo milling cutter 303 away from the workpiece surface. When the material is milling a hole, the blowing port of the high-speed blower 409 is rotated to the direction of the adsorption box 411. When the high-speed blower 409 blows in the direction of the adsorption box 411, the air pressure near the air collecting plate 410 is reduced, and the air flow near the milling hole is sucked into the air collecting plate 410. Since the air near the milling hole is mixed with smoke and dust during the milling process, the smoke and dust are sucked from the air collecting plate 410 and blown away to the inside of the adsorption box 411, and are adsorbed by the activated carbon particles placed in the adsorption box 411, so as to avoid the smoke and dust from being trapped in the material during the milling process. The smoke and dust generated during the milling process are scattered and inhaled by the workers, so as to ensure the health and safety of the workers. After the milling process is completed, the rotating disk 408 is rotated to turn the air outlet of the high-speed blower 409 to the material. Since there are many chips accumulated on the surface of the material during the milling process, the chips on the surface of the material are blown away by the high-speed blower 409 to avoid scratches on the surface of the material due to chips remaining on the surface of the material during the grinding process of the servo grinding disc 304, thereby improving the material grinding quality and reducing the labor intensity of the workers.

[0039] Considering that during the processing, in order to facilitate the automatic adjustment of the rotation angle of the high-speed blower 409 during the milling process of the servo milling cutter 303, a pull rope 401 is provided at the bottom of the first rack provided on the side wall of the second movable plate 302, and a fixed pulley 412 is provided above the pull rope 401. The free end of the pull rope 401 is connected to the second rack 402, and a gear rod 403 is meshed on one side of the second rack 402. A main gear 404 is provided at the bottom of the gear rod 403, and a sub-gear 405 is provided below the main gear 404. A worm 406 is provided at the end of the sub-gear 405. The worm 406 passes through the connecting box and rotates inside the connecting box. A worm wheel 407 is provided on one side of the worm 406, and a rotating disk 408 is provided on the top of the worm wheel 407. When the worm 406 drives the worm wheel 407 to rotate, the worm wheel 407 drives the worm wheel 407 to periodically rotate 180 degrees, so that the high-speed blower 409 provided on the surface of the rotating disk 408 always remains horizontal. In the process of processing the material, refer to Figure 3 As shown, the output shaft of the servo motor 305 drives the rotating gear 306 to rotate, so that the first rack provided on the side wall of the first movable plate 301 moves downward in the vertical direction, and the second movable plate 302 drives the servo grinding disc 304 to move in the opposite direction. When the second movable plate 302 moves, it pulls the pull rope 401, and the pull rope 401 moves in contact with the bottom of the fixed pulley 412 to pull the second rack 402 horizontally. During the movement, the second rack 402 drives the gear rod 403 to rotate. The main gear provided at the bottom of the gear rod 403 The gear 404 rotates coaxially, and the main gear 404 drives the sub-gear 405 to mesh and rotate during the rotation. The worm 406 provided at the end of the sub-gear 405 drives the worm wheel 407 to rotate, so that the rotating disk 408 provided on the top of the worm wheel 407 drives the high-speed blower 409 to rotate to 180°. At this time, the high-speed blower 409 blows air in the direction of the adsorption box 411, so that the smoke containing metal oxides generated by the servo milling cutter 303 during the milling process is adsorbed into the activated carbon particles inside the adsorption box 411.

[0040] After the milling hole is completed, in order to make the blowing port of the high-speed blower 409 automatically turn to the material, the reset component 500 includes a column 501 arranged on the side away from the second rack 402, and a slide bar 502 is slidably provided on the inner wall of the column 501, and the end of the slide bar 502 is connected to one side of the second rack 402, and a reset spring 503 is provided between the column 501 and the slide bar 502. When the second movable plate 302 drives the servo grinding disc 304 to move downward, the slide bar 502 at the end of the second rack 402 is subjected to the restoring force of the reset spring 503. Therefore, the slide bar 502 pulls the second rack 402 to move horizontally toward the column 501. At this time, the second rack 402 drives the gear rod 403 to rotate in the opposite direction, so that the rotating disk 408 above the worm gear 407 drives the blowing port of the high-speed blower 409 to turn to the material, thereby automatically blowing away the chips accumulated on the surface of the material, and adaptively adjusting the blowing direction of the high-speed blower 409 according to the processing conditions to improve the safety of the processing operation.

[0041] When in use, the material is placed on the surface of the electric suction cup 101 for fixing, and the rotating motor 200 drives the screw rod 201 to rotate the movable frame 202 on the surface of the screw rod 201 to move in the horizontal direction. At the same time, the movable seat 204 is controlled to move on the surface of the electric guide rail 203, and the output end of the servo motor 305 drives the rotating gear 306 to rotate, so that the first movable plate 301 and the second movable plate 302 move relative to each other. When the first movable plate 301 moves downward in the vertical direction to the milling hole position, the servo milling cutter 303 on the surface of the first movable plate 301 performs milling hole processing. When the milling hole processing is completed, there is no need to transport the material to the grinding machine. It is only necessary to control the rotating motor 200 to rotate in the opposite direction. At this time, the first movable plate 301 moves upward in the vertical direction, and the second movable plate 302 drives the servo grinding disc 304 to move downward in the vertical direction. The material with the milled hole is polished by the servo grinding disc 304, and the milling hole grinding of the material is automatically completed by the device, and the processing efficiency is improved.

[0042] The output shaft of the servo motor 305 drives the rotating gear 306 to rotate, so that the first rack provided on the side wall of the first movable plate 301 moves downward in the vertical direction, and the second movable plate 302 drives the servo grinding disc 304 to move in the opposite direction. When the second movable plate 302 moves, it pulls the pull rope 401, and the pull rope 401 moves in contact with the bottom of the fixed pulley 412 to pull the second rack 402 horizontally. The second rack 402 drives the gear rod 403 to rotate during the movement, and the main gear 404 provided at the bottom of the gear rod 403 rotates coaxially. During the rotation, the main gear 404 drives the sub-gear 405 to mesh and rotate, and the worm 406 provided at the end of the sub-gear 405 drives the worm wheel 407 to rotate, so that the rotating disk 408 provided on the top of the worm wheel 407 drives the high-speed blower 409 to rotate to 180°. At this time, the high-speed blower 409 blows air in the direction of the adsorption box 411, so that the smoke containing metal oxides generated by the servo milling cutter 303 during the milling process is The shavings are adsorbed into the activated carbon particles inside the adsorption box 411 to prevent smoke and dust from drifting, thereby ensuring the health and safety of the operators; when the milling operation is completed, the output shaft of the servo motor 305 drives the rotating gear 306 to rotate in the opposite direction, and the slide bar 502 pulls the second rack 402 to move horizontally toward the column 501.
