Description

Technical Field

[0001] The utility model relates to the technical field of drilling and milling machines, in particular to a multifunctional drilling and milling machine. Background Art

[0002] Drilling and milling machine is a multifunctional metal processing machine tool, which combines the functions of drilling machine and milling machine. This machine can usually perform processing operations such as drilling, milling, tapping, etc., and is widely used in machinery manufacturing, mold manufacturing, automotive parts processing, electronics industry, aerospace and other fields.

[0003] The Chinese patent with publication number CN208628503U discloses a multifunctional drilling and milling machine. The drilling and milling machine is provided with a retaining ring, a clamping plate and a fan, which facilitates the replacement of the drill bit, can better fix the parts, increase the processing effect of the equipment, and bring better prospects for use.

[0004] However, in actual processing, it is often necessary to process the workpiece at different angles. However, the above patent cannot adjust the angle of the workpiece during the processing, resulting in workers frequently disassembling and reinstalling the workpiece to adjust the angle, which increases the processing time and reduces the processing efficiency. In addition, during the processing, friction heat is generated when the drill bit contacts and rotates with the metal. If the heat is too high, it will cause the metal to heat up locally and produce smoke. When the operator inhales excessive smoke, it will affect the respiratory tract and physical health. Utility Model Content

[0005] The utility model aims to provide a multifunctional drilling and milling machine which can adjust the angle of a workpiece during processing and avoid the smoke generated during processing from affecting the respiratory tract and health of workers, so as to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a multifunctional drilling and milling machine, comprising a base, a support rod is installed on the outer surface of the base, a chassis is installed on the top of the support rod, a drill bit is arranged on the lower side of the chassis, a turntable is rotatably installed on the upper surface of the base through a connecting shaft, and an angle adjustment mechanism capable of adjusting the angle of the turntable is arranged on the upper surface of the base. A processing table is installed on the upper surface of the turntable through a horizontal moving module, and a fixing mechanism capable of fixing a workpiece is arranged on the upper surface of the processing table. A smoke removal mechanism is arranged on the outer side of the drill bit.

[0007] It can be seen that through the setting of the angle adjustment mechanism, the angle of the turntable can be adjusted, and then the angle of the workpiece can be adjusted during the processing. There is no need to frequently disassemble and reinstall the workpiece for angle adjustment, which reduces the processing time and improves the processing efficiency. Moreover, through the setting of the fixing mechanism, the workpiece can be quickly and stably clamped and fixed to improve the processing effect. Through the setting of the smoke removal mechanism, the smoke generated during the processing can be absorbed and discharged after filtering, thereby avoiding the operator from inhaling excessive smoke, causing damage to the respiratory tract and physical health.

[0008] Furthermore, the angle adjustment mechanism includes two side plates installed on the upper surface of the base, a worm is rotatably installed between the two side plates, a first hand wheel is installed at the end of the worm, a worm wheel is sleeved on the outer surface of the turntable, and the worm wheel is meshingly connected with the worm.

[0009] When the angle of the workpiece needs to be adjusted, the first hand wheel can be turned to drive the worm to rotate. Since the worm and the worm wheel are meshed with each other, the turntable can be driven to rotate to achieve the purpose of adjusting the angle of the workpiece.

[0010] Furthermore, the fixing mechanism includes four fixing blocks installed at the four corners of the upper surface of the processing table, a threaded rod with a pair of reverse threads is rotatably installed between two opposite fixing blocks, two clamping plates parallel to each other are provided on the upper surface of the processing table, and the two ends of the two clamping plates are respectively installed on the reverse threads of the two threaded rods. A pulley group is provided at one end of the two threaded rods, and a second hand wheel is installed at the other end of one of the threaded rods.

[0011] After placing the workpiece on the processing table, the second hand wheel can be turned to drive the threaded rod connected to it to rotate. Through the transmission action of the pulley group, the two threaded rods rotate at the same time. Because of the setting of the reverse threads on the two threaded rods, the two clamps can be moved inward at the same time and clamped on the two sides of the workpiece to achieve the purpose of fixing it. When the second hand wheel is turned in the opposite direction, the two clamps can be driven away from each other, and the fixation of the workpiece can be cancelled and it can be taken out. Compared with the fixing method in the comparative patent, which fixes the workpiece by sliding the clamp and then fixing the slide plate with bolts, this method is not only complicated to operate, but also has a poor fixing effect. It is easy for the workpiece to shake during the processing, and its practicality is low.

[0012] Furthermore, the smoke removal mechanism includes an annular tube arranged outside the drill bit, and the annular tube is coaxially arranged with the drill bit, a plurality of air suction tubes are coaxially arranged on the inner side of the annular tube, two side blocks are installed on the outer surface of the annular tube, a telescopic rod is installed on the upper surface of the side block, the end of the telescopic rod is connected to the chassis, a spring is sleeved on the outer surface of the telescopic rod, and the two ends of the spring are respectively abutted against the side block and the chassis. A fan is installed on the outer surface of the chassis, a hose is connected to the air suction end of the fan, and the end of the hose is connected to the annular tube, and an activated carbon filter is detachably installed on the air outlet end of the fan.

[0013] When the drill bit is drilling a hole in a workpiece, the fan can be started. The suction generated by the fan acts on the annular tube through the hose, so that multiple suction pipes can generate suction at the same time and directly suck away the generated smoke. The sucked smoke is discharged from the air outlet of the fan into the activated carbon filter. After being filtered by the activated carbon filter, harmful substances in the smoke can be removed and discharged, thereby preventing operators from inhaling excessive smoke, causing damage to the respiratory tract and physical health.

[0014] Furthermore, a filter screen is provided at the end of the air suction pipe, and the filter screen is made of stainless steel.

[0015] By setting the filter, the inside of the suction pipe can be filtered to prevent debris from entering the suction pipe during the processing, causing blockage inside the hose and damage to the fan.

[0016] Furthermore, a guide groove is provided on the upper surface of the base, and a guide wheel is installed at the bottom of the turntable, and the guide wheel is arranged inside the guide wheel.

[0017] By setting the guide groove and the guide wheel, the bottom stress points of the turntable can be increased and the supporting strength thereof can be improved.

[0018] Compared with the prior art, the beneficial effects of the utility model are:

[0019] 1. The utility model drives the worm to rotate by turning the first hand wheel. Since the worm and the worm wheel are meshed with each other, the turntable can be driven to rotate to achieve the purpose of adjusting the angle of the workpiece. The processing angle can be changed at will during the processing, and there is no need to frequently disassemble and reinstall the workpiece for angle adjustment, thereby reducing the processing time and improving the processing efficiency;

[0020] 2. The utility model starts the fan to generate suction force to absorb, filter and discharge the smoke generated by the drill bit, thereby preventing the operator from inhaling excessive smoke, which may cause damage to the respiratory tract and health. In addition, the annular tube can be extended and retracted up and down on the outside of the drill bit by setting the telescopic rod and the spring. Regardless of the drilling depth of the drill bit, the annular tube can be attached to the surface of the workpiece to achieve a good demisting effect.

[0021] 3. The utility model can drive the two threaded rods to rotate simultaneously by turning the second hand wheel, so that the two clamping plates can move inward at the same time and clamp on the two sides of the workpiece, which can provide a good fixing effect for the workpiece and avoid the shaking of the workpiece during the processing, and has strong practicality.

[0031] A multifunctional drilling and milling machine includes a base 100, a support rod 101 is installed on the outer surface of the base 100, a chassis 102 is installed on the top of the support rod 101, a drill bit 103 is arranged on the lower side of the chassis 102, a turntable 105 is rotatably installed on the upper surface of the base 100 through a connecting shaft 104, and an angle adjustment mechanism 200 is arranged on the upper surface of the base 100, which can adjust the angle of the turntable 105. Through the setting of the angle adjustment mechanism 200, the angle of the workpiece can be adjusted during the processing, reducing the processing time and improving the processing efficiency. A processing table 107 is installed on the upper surface of the turntable 105 through a horizontal moving module 106, and a fixing mechanism 300 is arranged on the upper surface of the processing table 107 for fixing the workpiece. Through the setting of the fixing mechanism 300, the workpiece can be quickly fixed to avoid the shaking of the workpiece during the processing, and the practicality is strong. A smoke removal mechanism 400 is provided on the outside of the drill bit 103. Through the setting of the smoke removal mechanism 400, the smoke generated by the processing can be absorbed, filtered and discharged, thereby preventing the operator from inhaling excessive smoke, causing damage to the respiratory tract and physical health. A guide groove 600 is provided on the upper surface of the base 100, and a guide wheel 601 is installed at the bottom of the turntable 105. The guide wheel 601 is arranged inside the guide wheel 601.

[0032] See also Figure 1 and Figure 4 The angle adjustment mechanism 200 includes two side plates 201 installed on the upper surface of the base 100, a worm 202 is rotatably installed between the two side plates 201, a first hand wheel 204 is installed at the end of the worm 202, a worm wheel 203 is sleeved on the outer surface of the turntable 105, and the worm wheel 203 is meshed with the worm 202. When the angle of the workpiece needs to be adjusted, the first hand wheel 204 can be turned to drive the worm 202 to rotate. Since the worm 202 and the worm wheel 203 are meshed with each other, the turntable 105 can be driven to rotate, thereby achieving the purpose of adjusting the angle of the workpiece.

[0033] See also Figure 1 and Figure 2 The fixing mechanism 300 includes four fixing blocks 301 installed at the four corners of the upper surface of the processing table 107, and a threaded rod 302 with a pair of reverse threads is rotatably installed between two opposite fixing blocks 301. Two parallel clamps 303 are provided on the upper surface of the processing table 107, and the two ends of the two clamps 303 are respectively installed on the reverse threads of the two threaded rods 302. The second hand wheel 305 is installed at one end of the two threaded rods 302 for transmission, and the second hand wheel 305 is installed at the other end of one of the threaded rods 302. After the workpiece is placed on the processing table 107, the second hand wheel 305 can be turned to drive the threaded rod 302 connected thereto to rotate. The two threaded rods 302 are rotated at the same time through the transmission action of the pulley group 304. Because of the setting of the reverse threads on the two threaded rods 302, the two clamping plates 303 can be moved inward at the same time and clamped on the two sides of the workpiece to achieve the purpose of fixing it. When the second hand wheel 305 is turned in the opposite direction, the two clamping plates 303 can be driven away from each other, and the fixation of the workpiece can be canceled and it can be taken out. Compared with the fixing method in the comparative patent, the workpiece is fixed by sliding the clamping plate and then the sliding plate is fixed by bolts. This method is not only complicated to operate, but also has a poor fixing effect. It is easy for the workpiece to shake during the processing, and its practicality is low.

[0034] See also Figure 1 and Figure 3The smoke removal mechanism 400 includes an annular tube 401 arranged on the outside of the drill bit 103, and the annular tube 401 is coaxially arranged with the drill bit 103. A plurality of suction tubes 402 are coaxially arrayed on the inner side of the annular tube 401. Two side blocks 403 are installed on the outer surface of the annular tube 401. A telescopic rod 404 is installed on the upper surface of the side block 403. The end of the telescopic rod 404 is connected to the chassis 102. A spring 405 is sleeved on the outer surface of the telescopic rod 404. The two ends of the spring 405 are respectively abutted against the side block 403 and the chassis 102. A fan 406 is installed on the outer surface of the chassis 102, and a hose 407 is connected to the suction end of the fan 406. The end of the hose 407 is connected to the annular tube 401, and an activated carbon filter 408 is detachably installed on the air outlet end of the fan 406. When the drill bit 103 drills a hole in the workpiece, the fan 406 can be started, and the suction force generated by the fan 406 acts on the annular tube 401 through the hose 407, so that multiple suction pipes 402 can generate suction at the same time and directly suck away the generated smoke. The sucked smoke is discharged from the air outlet end of the fan 406 into the activated carbon filter 408. After being filtered by the activated carbon filter 408, harmful substances in the smoke can be removed and discharged, thereby preventing the operator from inhaling excessive smoke, causing damage to the respiratory tract and physical health. The activated carbon filter 408 is connected to the fan 406 by a threaded connection, which is convenient for regular replacement of the activated carbon filter 408 to ensure its filtering effect. A filter screen 500 is provided at the end of the suction pipe 402. The filter screen 500 is made of stainless steel. Through the setting of the filter screen 500, the interior of the suction pipe 402 can be filtered to prevent debris generated during the processing from entering the suction pipe 402, causing blockage in the hose 407 and damage to the fan 406.

[0035] The specific workflow and working principle of this device are as follows.

[0036] When in use, the worker first places the workpiece on the upper surface of the processing table 107 and between the two clamping plates 303, and then turns the second hand wheel 305 to drive the threaded rod 302 connected to it to rotate. Through the transmission action of the pulley group 304, the two threaded rods 302 rotate at the same time. Because of the setting of the reverse threads on the two threaded rods 302, the two clamping plates 303 can move inward at the same time and clamp on the two sides of the workpiece to fix it. Then the drill bit 103 can be lowered to process the workpiece. During the processing, the fan 406 can be started. The suction force generated by the fan 406 acts on the annular tube 401 through the hose 407, so that the multiple suction pipes 402 can generate suction at the same time and directly suck away the generated smoke. Moreover, since the multiple suction pipes 402 are evenly distributed in an array with the drill bit 103 as the axis Therefore, the smoke can be adsorbed in all directions without dead angles to avoid residue. The sucked smoke is discharged into the activated carbon filter 408 from the air outlet of the fan 406. After being filtered by the activated carbon filter 408, harmful substances in the smoke can be removed and discharged, thereby avoiding the operator from inhaling excessive smoke, causing damage to the respiratory tract and physical health. In addition, during the processing, the horizontal position of the processing table 107 can be adjusted by the horizontal moving module 106, and then the horizontal position of the workpiece can be adjusted. When the processing angle of the workpiece needs to be adjusted, the first hand wheel 204 can be turned to drive the worm 202 to rotate. Since the worm 202 and the worm wheel 203 are meshed with each other, the turntable 105 can be driven to rotate, thereby achieving the purpose of adjusting the angle of the workpiece. There is no need to frequently disassemble and reinstall the workpiece for angle adjustment, and the use effect is better.
