Description

Technical Field

[0001] This utility model relates to the field of CNC machining tool technology, specifically to a drilling and milling equipment for multi-face machining of workpieces. Background Technology

[0002] Metalworking processes often involve multiple steps such as drilling, milling, and tapping, all of which are crucial to the final quality and performance of the product. In traditional methods, these steps are typically performed on different machines, meaning metal workpieces need to be frequently moved between them. This process is not only inefficient and increases production costs, but the repeated handling and repositioning can also lead to a decrease in machining accuracy.

[0003] To address this challenge, multi-functional drilling and milling machines integrating drilling, milling, and tapping have been introduced to the market. These machines, through preset programs, can flexibly control cutting tools (drills, milling cutters, or taps) to perform drilling, milling, or tapping operations on workpieces fixed to a worktable. Operators can complete all necessary machining steps on a single machine, eliminating the need to move workpieces between different machines, thus significantly improving machining efficiency and accuracy.

[0004] However, despite the significant improvements in functionality and efficiency compared to traditional equipment, tapping and milling machines still have some limitations in practical applications. Specifically, most existing tapping and milling machines have fixed worktables or can only rotate around a vertical axis, both of which have drawbacks. Fixed worktables limit the machine to machining only one side of the workpiece (the side opposite the tool), failing to meet the need for multi-sided machining and severely restricting the machine's processing range and flexibility. While worktables that can rotate around a vertical axis allow machining of multiple sides of the workpiece by rotating and flipping it, fulfilling the need for multi-sided machining, they still have limitations. Specifically, this design results in the tool and the opposite side to be machined always being perpendicular to each other. This means the tool can only perform tapping and milling operations along the vertical direction of the side to be machined, and the machining angle cannot be adjusted. Therefore, when inclined drilling, milling, or tapping is required, this type of machine cannot meet the requirements, necessitating the use of other equipment to complete these special machining operations. This not only increases the initial investment cost of the equipment but also occupies more production space.

[0005] Therefore, it is necessary to develop a drilling and milling machine for multi-faceted machining of workpieces, capable of machining workpieces from multiple faces and angles. Utility Model Content

The rotary table and the cutter head are both located in the working chamber. The waste discharge component is used to collect the coolant used in the working chamber and the waste generated during processing.

[0016] Further, the aforementioned waste discharge component includes a funnel and a collection box. The funnel is located in the working chamber and below the cutter head. The collection box contains a chip collection trough and a water collection chamber. The chip collection trough is located below and communicates with the funnel, and the water collection chamber is located below the chip collection trough. Multiple filter holes, communicating with the water collection chamber, are evenly distributed at the bottom of the chip collection trough. The filter holes are used to separate coolant and waste chips, and the water collection chamber is used to collect the separated coolant.

[0017] Further configuration: the aforementioned chip collection groove includes an input end and an output end, with the input end of the chip collection groove connected to the funnel;

[0018] The drilling and milling equipment used for multi-face machining of workpieces also includes a chip removal device and a chip collection trolley. The chip removal device is located on the collection box and is used to move the waste chips in the chip collection groove from the input end to the output end. The chip collection trolley is movably located at the output end of the chip collection groove and is used to collect the waste chips discharged from the chip collection groove by the chip removal device.

[0019] In a further configuration, the aforementioned chip removal device includes a screw conveyor and a drive mechanism. The screw conveyor is rotatably disposed within the chip collection trough, and the drive mechanism is disposed on the frame and is connected to the screw conveyor via a transmission. The drive mechanism is used to drive the screw conveyor to rotate, so as to move the waste chips in the chip collection trough from the input end to the output end.

[0020] Furthermore, the aforementioned drilling and milling equipment for multi-face machining of workpieces also includes a pressing device. The pressing device includes a pressing head and a lifting mechanism. The pressing head is located above the rotary table, and the lifting mechanism is mounted on the frame. The output end of the lifting mechanism is rotatably connected to the pressing head around the X-axis. The lifting mechanism is used to drive the pressing head to move up and down, pressing or releasing the workpiece on the workstation.

[0021] Further configuration: the aforementioned drive device includes an X-axis drive mechanism, a Y-axis drive mechanism, and a Z-axis drive mechanism.

[0023] (III) Beneficial Effects

[0024] Compared with the prior art, the tapping and milling equipment for multi-face machining of workpieces provided by this utility model has the following beneficial effects:

[0025] When using this drilling and milling machine for multi-face machining of workpieces, firstly, the workpiece is placed and positioned on the rotary table, with any side of the workpiece facing the cutter head. Then, the cutter head and drive device are activated, working together to perform drilling, milling, or tapping on any position on that side of the workpiece. After machining that side, the rotary table drives the workpiece to rotate around its center line, flipping it so that the next side to be machined faces the cutter head. Finally, the cutter head and drive device work together to perform drilling, milling, or tapping on the next side to be machined, repeating this process continuously to complete multi-face machining of the workpiece. During the above machining process, the cutter head is by default perpendicular to the opposite side to be machined. When tilting the drilling, milling, or tapping is required, simply activate the flipping mechanism to drive the rotary table and the workpiece on it to rotate back and forth around the X-axis by the required machining angle, thus tilting the cutter head to the opposite side to be machined. Then, the cutter head and drive device are activated to perform tilting drilling, milling, or tapping on that side of the workpiece. As can be seen, compared with the existing technology, this utility model can not only perform multi-face processing on the workpiece, but also perform multi-angle processing on the workpiece to meet processing requirements.

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0040] This utility model provides a drilling and milling machine for multi-face machining of workpieces, which solves the problem of how to perform multi-face and multi-angle machining on workpieces.

[0041] See Figure 1 As shown, Figure 1 The image shows a perspective view of a drilling and milling machine for multi-face machining of a workpiece in the embodiment. The drilling and milling machine includes a frame 1, a tilting mechanism 2, a rotary table 3, a cutting head 4, and a drive device 5.

[0042] The flipping mechanism 2 is mounted on the frame 1 by screwing or welding and is connected to the rotary table 3 via a transmission mechanism. The flipping mechanism 2 drives the rotary table 3 to flip around the X-axis. The rotary table 3 has a workstation 31 for supporting and positioning the workpiece. The rotary table 3 drives the workpiece to rotate around its centerline. The cutting head 4 is located on one side of the rotary table 3. The drive device 5 is mounted on the frame 1 by screwing or welding and is connected to the cutting head 4 via a transmission mechanism. The drive device 5 drives the cutting head 4 to move relative to the rotary table 3 to perform drilling, milling, or tapping operations on the workpiece at workstation 31.

[0043] The X-axis extends along a horizontal direction and is perpendicular to the axis of the cutter head 4.

[0044] When using the drilling and milling equipment for multi-face machining of workpieces described above, the workpiece is first placed and positioned on station 31 of the rotary table 3, with any side of the workpiece facing the cutter head 4. Then, the cutter head 4 and drive device 5 are activated, working together to perform drilling, milling, or tapping on any position on that side of the workpiece. After machining that side, the rotary table 3 drives the workpiece to rotate around its centerline, flipping it so that the next side to be machined faces the cutter head 4. Finally, the cutter head 4 and drive device 5 work together to perform drilling, milling, or tapping on the next side to be machined. This process is repeated continuously to complete the multi-face machining of the workpiece.

[0045] During the aforementioned processing, the cutter head 4 is positioned perpendicular to the opposite side to be processed by default. Thus, the cutter head 4 can perform drilling and milling operations on the workpiece along the vertical direction of that side. When inclined drilling, milling, or tapping is required, simply activating the tilting mechanism 2 drives the rotary table 3 and the workpiece on it to rotate back and forth around the X-axis by the required processing angle. This causes the cutter head 4 to be tilted relative to the opposite side to be processed. Then, activating the cutter head 4 and the drive device 5 allows for inclined drilling, milling, or tapping on that side of the workpiece, thereby producing holes or grooves with an inclination angle of 15° or 45° to the side to be processed.

[0046] In summary, it can be seen that, compared with the prior art, this utility model can not only perform multi-face processing on the workpiece, but also multi-angle processing on the workpiece, thus meeting processing requirements.

[0047] The aforementioned flipping mechanism 2 can use a servo motor or stepper motor or other rotary drive mechanism to achieve precise control of the flipping angle of the rotary table 3. Its output end 12212 is connected to the rotary table 3 by means of screwing or welding.

[0048] The aforementioned cutting head 4 can be selected from any cutting tool such as a drill bit, end mill, or tap according to processing requirements. Furthermore, a tool magazine 13 can be installed on the frame 1 of the aforementioned drilling and tapping equipment to store various cutting tools such as drill bits, end mills, or taps.

[0049] See Figure 1 and Figure 2 As shown, Figure 2This is a schematic diagram of the structure of the frame, flipping mechanism, rotary table, cutter head, and drive device in one embodiment. In one embodiment of the rotary table 3, the rotary table 3 includes a rotary drive mechanism 32 and a rotary seat 33. A workstation 31 is provided on the rotary seat 33. The rotary drive mechanism 32 is mounted on the output end 12212 of the flipping mechanism 2 by means of screwing or welding, and the output end 12212 of the rotary drive mechanism 32 is connected to the rotary seat 33 by means of screwing or welding. The rotary drive mechanism 32 is used to drive the rotary seat 33 to rotate. Thus, when the rotary drive mechanism 32 is activated, it can drive the rotary seat 33 and the workpiece on it to rotate together, realizing the rotation and flipping of the workpiece on the rotary table 3. Combined with the drive device 5 and the drill bit, it is possible to process any side of the workpiece on the rotary table 3.

[0050] The aforementioned rotary drive mechanism 32 can use existing rotary drive mechanisms such as servo motors or indexing plates.

[0051] See Figure 1 and Figure 2 As shown, based on the above embodiment, the frame 1 is equipped with a working chamber 11 and a waste discharge component 12. The rotary table 3 and the cutting head 4 are both located inside the working chamber 11. The waste discharge component 12 is used to discharge the used coolant and the waste generated during processing from the working chamber 11. In this way, when the tapping and milling machine is processing, the rotary table 3 and the cutting head 4 are enclosed inside the working chamber 11, which not only protects the processing process from disturbance, but also encloses the used coolant and the metal waste and dust generated during processing inside the working chamber 11 to prevent pollution of the external environment or injury to the workers; while the waste discharge component 12 can automatically discharge the coolant and waste in the working chamber 11 to avoid affecting the processing, thereby improving the processing quality, effectively reducing the intensity of manual labor, and facilitating subsequent unified recycling and disposal.

[0052] See Figure 2 , Figure 3 and Figure 4 As shown, Figure 3 This is a right view of the frame, tilting mechanism, and rotary table in the embodiment. Figure 4The diagram shows a cross-sectional view of the collection box and screw conveyor in one embodiment. In one implementation of the waste discharge component 12, the waste discharge component 12 includes a funnel 121 and a collection box 122. The funnel 121 is located within the working chamber 11 by means of screwing or welding, and is positioned below the cutter head 4. The collection box 122 has a chip collection groove 1221 and a water collection chamber 1222. The chip collection groove 1221 is located below and communicates with the funnel 121. The water collection chamber 1222 is located below the chip collection groove 1221. Multiple filter holes 1223 communicating with the water collection chamber 1222 are evenly distributed at the bottom of the chip collection groove 1221. The filter holes 1223 are used to separate coolant and waste chips. The water collection chamber 1222 is used to collect the separated coolant. Thus, the waste discharge component 12 guides the coolant and the waste mixed therein in the working chamber 11 through the funnel 121 and discharges them downwards into the chip collection tank 1221 of the collection box 122. The coolant flowing into the chip collection tank 1221 can flow into the water collection chamber 1222 through the filter hole 1223, leaving the waste in the chip collection tank 1221, thereby achieving the effect of automatically separating the coolant and waste, and automatically recovering the separated coolant and waste for subsequent classification and processing.

[0053] See Figure 2 , Figure 3 and Figure 4 As shown, based on the above embodiment, the chip collection trough 1221 includes an input end 12211 and an output end 12212. The input end 12211 of the chip collection trough 1221 is connected to the funnel 121. The drilling and milling equipment for multi-face machining of workpieces also includes a chip removal device and a chip collection trolley 7. The chip removal device is installed on the collection box 122 and is used to move the waste chips in the chip collection trough 1221 from the input end 12211 to the output end 12212. The chip collection trolley 7 is movably disposed at the output end 12212 of the chip collection trough 1221 and is used to collect the waste chips discharged from the chip collection trough 1221 by the chip removal device. Thus, during the machining process, waste chips are continuously discharged through the funnel 121 to the input end 12211 of the chip collection trough 1221, which causes the waste chips to easily accumulate at the input end 12211 of the chip collection trough 1221, and may even overflow the chip collection trough 1221, polluting the ground and requiring manual cleaning and recycling. To address this issue, this invention utilizes a chip removal device to move waste chips from the input end 12211 to the output end 12212 within the chip collection trough 1221. When the waste chips at the output end 12212 overflow the chip collection trough 1221, they automatically fall into and are collected in the external chip collection trolley 7, effectively preventing waste chips from polluting the ground and greatly facilitating recycling for workers.

[0054] See Figure 2 , Figure 3 and Figure 4As shown, in one embodiment of the chip removal device, the device includes a screw conveyor 61 and a drive mechanism 62. The screw conveyor 61 is rotatably connected to the chip collection trough 1221. The drive mechanism 62 is mounted on the frame 1 by means of screwing or welding and is drively connected to the screw conveyor 61. The drive mechanism 62 drives the screw conveyor 61 to rotate, thereby moving the waste chips in the chip collection trough 1221 from the input end 12211 to the output end 12212. Thus, when the drive mechanism 62 drives the screw conveyor 61 to rotate, the helical blades of the screw conveyor 61 rotate accordingly, thereby achieving the function of automatically conveying the waste chips in the chip collection trough 1221.

[0055] The aforementioned screw conveyor 61 has helical blades extending axially. The aforementioned drive mechanism 62 can use an existing rotary drive mechanism such as a motor or electric motor, and its output end 12212 is connected to one end of the screw conveyor 61 by means of screwing or welding.

[0056] See Figure 1 and Figure 3 As shown, based on any of the above embodiments, the drilling and milling equipment for multi-face machining of workpieces further includes a pressing device 9. The pressing device 9 includes a pressing head 91 and a lifting mechanism 92, with the pressing head 91 located above the rotary table 3. The lifting mechanism 92 is mounted on the frame 1 by means of screwing or welding, and the output end 12212 of the lifting mechanism 92 is rotatably connected to the pressing head 91 around the X-axis. The lifting mechanism 92 is used to drive the pressing head 91 to move up and down, pressing or releasing the workpiece on the workstation 31. In this way, the pressing device 9 can press the workpiece carried on the workstation 31, realizing the positioning function of the workpiece and effectively preventing the workpiece from shifting or being damaged due to vibration caused by rotation or processing; and when the rotary mechanism drives the rotary table 3 and the workpiece on it to rotate back and forth around the X-axis, the pressing head 91 of the pressing device 9 can rotate accordingly, which not only avoids the pressing head 91 interfering with the back and forth rotation of the workpiece, but also ensures that the pressing head 91 always maintains contact with the workpiece surface, ensuring the positioning function of the pressing device 9.

[0057] The aforementioned lifting mechanism 92 can use existing telescopic drive mechanisms 62 such as telescopic cylinders or telescopic poles, or it can use existing linear displacement drive mechanisms 62 such as servo motor-lead screw nut linear modules or servo linear motors.

[0058] See Figure 1 and Figure 3 As shown, based on the above embodiment, the drilling and milling equipment for multi-face machining of workpieces also includes a workpiece clamp 8. The workpiece clamp 8 is mounted on the rotary table 3 and is used to clamp or release the workpiece on the workstation 31. Thus, the combination of the workpiece clamp 8 and the pressing device 9 can further fix the workpiece, thereby further preventing the workpiece from shifting during the machining process.

[0059] The workpiece fixture 8 described above can automatically position the workpiece using existing grippers or chucks, or manually position the workpiece using a fixture adapted to the workpiece.

[0060] See Figure 2 As shown, in one embodiment of the drive device 5, the drive device 5 includes an X-axis drive mechanism 51, a Y-axis drive mechanism 52, and a Z-axis drive mechanism 53. The X-axis drive mechanism 51 is mounted on the frame 1 by means of screwing or welding. The output end 12212 of the X-axis drive mechanism 51 is connected to the Y-axis drive mechanism 52 by means of screwing or welding. The output end 12212 of the Y-axis drive mechanism 52 is connected to the Z-axis drive mechanism 53 by means of screwing or welding. The output end 12212 of the Z-axis drive mechanism 53 is connected to the cutter head 4 by means of screwing or welding. The X-axis drive mechanism 51 is used to drive the cutter head 4 to move along the X-axis direction, the Y-axis drive mechanism 52 is used to drive the cutter head 4 to move along the Y-axis direction (the Y-axis and X-axis are perpendicular to each other on the horizontal plane), and the Z-axis drive mechanism 53 is used to drive the cutter head 4 to move in the vertical direction. Thus, the drive device 5, through the cooperation of the X-axis drive mechanism 51, the Y-axis drive mechanism 52 and the Z-axis drive mechanism 53, can drive the cutter head 4 to process any position on the opposite side of the workpiece.

[0061] The X-axis drive mechanism 51, Y-axis drive mechanism 52 and Z-axis drive mechanism 53 mentioned above can all use existing servo motor-lead screw nut linear modules or servo linear motors and other linear displacement drive mechanisms 62 to achieve precise control of the movement of the cutter head 4.

[0062] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
