DETAILED DESCRIPTION

[0017] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0018] Example 1: Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Fig.10A multifunctional composite tool quick switching device for a vertical lathe-milling and grinding composite machine tool comprises a machine tool body 1, on which a fixture for clamping a workpiece is arranged, on which a base 101 is fixedly installed, and further comprises: a frame 2, which is slidably connected to the base 101; a mounting plate 3, which is lifted and connected to the frame 2; a mounting seat 4, which is slidably connected to the mounting plate 3; a connecting seat 5, which is fixedly connected to the mounting seat 4, wherein an annular tool holder 501 is rotatably connected to the connecting seat 5, and the outer wall of the annular tool holder 501 is equidistant from the circumference. There are multiple tool seats 502 that are detachably connected, and the tool seats 502 are provided with positioning grooves 503 for limiting and fixing the tool body 504. The diameters of the positioning grooves 503 on the multiple tool seats 502 are arranged in descending order, and are used to adapt to tool bodies 504 of different models; a motor 4 506 is fixedly installed on the connecting seat 5, wherein the annular tool holder 501 is fixedly connected to the output end of the motor 4 506; a clamping component is arranged on the tool seat 502, wherein the tool body 504 is detachably connected to the positioning groove 503 through the clamping component; During the process of processing the workpiece, when the tool needs to be replaced, start motor 4 506, and motor 4 506 drives the annular tool holder 501 to rotate, so that the tool body 504 of the required model rotates to the working position, thereby realizing rapid switching of the tool. The diameters of the positioning grooves 503 on the multiple tool holders 502 decrease successively, and can be adapted to tool bodies 504 of different models, so that one machine tool can use a variety of tools for processing, thereby improving the versatility and processing efficiency of the machine tool. Moreover, the tool body 504 is detachably connected to the positioning groove 503 through a clamping component, which facilitates the replacement and maintenance of the tool, reduces the tool changing time, and further improves the production efficiency. Then, by sliding the frame 2 on the base 101, lifting the mounting plate 3 on the frame 2, and sliding the mounting seat 4 on the mounting plate 3, the tool body 504 can be moved to a suitable processing position to process the workpiece.

[0019] A screw rod 202 is rotatably connected to the base 101, a motor 201 is fixedly installed on the base 101, the screw rod 202 is fixedly connected to the output end of the motor 201, both sides of the upper end surface of the base 101 are fixedly connected to a guide rail 204, the frame 2 is slidably connected to the guide rail 204, a screw sleeve 203 is fixedly installed on the frame 2, and the screw sleeve 203 is threadedly connected to the screw rod 202; Start the motor 201, and the motor 201 drives the screw 202 to rotate. Since the screw sleeve 203 is threadedly connected to the screw 202, and the frame 2 is restricted from rotating by the guide rail 204, the frame 2 will slide on the base 101 along the guide rail 204, thereby adjusting the lateral position of the tool and improving the processing accuracy. At the same time, the guide rail 204 guides the frame 2 and ensures the sliding stability of the frame 2.

[0020] The frame 2 is rotatably connected with a screw rod 2 302, the frame 2 is fixedly installed with a motor 2 301, the screw rod 2 302 is fixedly connected to the output end of the motor 2 301, the frame 2 is symmetrically fixedly connected with a guide rail 2 304, the mounting plate 3 is slidably connected to the guide rail 2 304, the mounting plate 3 is fixedly connected with a screw sleeve 2 303, and the screw sleeve 2 303 is threadedly connected to the screw rod 2 302; Start the motor 301, and the motor 301 drives the screw 302 to rotate. Since the screw sleeve 303 is threadedly connected to the screw 302, and the mounting plate 3 is restricted from rotating by the guide rail 304, the mounting plate 3 will move up and down on the frame 2 along the guide rail 304, so as to adjust the height position of the tool to meet different processing requirements and improve the processing flexibility and accuracy. The guide rail 304 ensures the stability of the mounting plate 3 when it is lifted and lowered.

[0021] The mounting plate 3 is rotatably connected with a screw rod 3 402, the mounting plate 3 is fixedly mounted with a motor 3 401, the screw rod 3 402 is fixedly connected to the output end of the motor 3 401, the mounting plate 3 is fixedly connected with a guide rail 3 404, the mounting seat 4 is slidably connected to the guide rail 3 404, the mounting seat 4 is fixedly connected with a screw sleeve 3 403, and the screw sleeve 3 403 is threadedly connected to the screw rod 3 402; Start motor three 401, which drives screw three 402 to rotate. Since sleeve three 403 is threadedly connected to screw three 402, and mounting base 4 limits rotation through guide rail three 404, mounting base 4 will slide on mounting plate 3 along guide rail three 404, thereby further adjusting the lateral position of the tool, improving the accuracy and flexibility of lateral position adjustment of the tool, and meeting more complex processing requirements. Guide rail three 404 ensures the stability of sliding of mounting base 4.

[0022] Example 2: Reference Figure 7 , Fig.10 , Fig.11 , a multifunctional composite tool quick switching device for a vertical turning, milling and grinding composite machine tool, is basically the same as that of Example 1, and further comprises a plurality of fixing bolts 505, and a tool holder 502 is detachably connected to the annular tool holder 501 through the plurality of fixing bolts 505; When the knife holder 502 needs to be replaced or maintained, the knife holder 502 can be removed from the ring-shaped knife holder 501 by unscrewing the fixing bolt 505. When installing, align the knife holder 502 to the position and then tighten it with the fixing bolt 505. In summary, the tool holder 502 and the annular tool holder 501 are connected by fixing bolts 505. This connection method is simple, reliable and easy to operate. When the tool holder 502 is damaged or needs to be replaced with a tool holder 502 of different specifications, it can be easily and quickly disassembled and installed, thereby improving the maintainability of the equipment and the flexibility of tool configuration.

[0023] The clamping component includes a plug-in block 6 and a plug-in slot 601 provided at the upper end of the tool body 504 and used in conjunction with the plug-in block 6. A slide slot 602 is provided on the plug-in block 6. A clamping block 603 is slidably connected in the slide slot 602. The upper end surface of the clamping block 603 is inclined. A spring 604 is provided in the slide slot 602. One end of the spring 604 is fixedly connected to the clamping block 603, and the other end is fixedly connected to the inner wall of the slide slot 602. When installing the tool body 504, align the insertion slot 601 of the tool body 504 with the insertion block 6 and insert it. The inner wall of the insertion slot 601 will squeeze the inclined surface of the clamping block 603, so that the clamping block 603 shrinks into the slide slot 602, and the spring 604 is compressed. When the insertion slot 601 is fully inserted into the appropriate position, the spring 604 rebounds, pushing the clamping block 603 to pop out and clamp on the surface of the upper end of the tool body 504, so as to fix the tool body 504. When disassembling the tool body 504, a certain external force is applied to make the clamping block 603 shrink into the slide slot 602 again, and the tool body 504 can be pulled out. In summary, the elastic force of the spring 604 is utilized to make the clamping block 603 clamped on the surface of the upper end portion of the tool body 504 or detached from the surface of the upper end portion of the tool body 504, thereby realizing the rapid installation and disassembly of the tool body 504. This clamping method is simple to operate and can complete the tool replacement in a short time, thereby improving the tool changing efficiency. At the same time, after the clamping block 603 is clamped on the surface of the upper end portion of the tool body 504, the stability of the installation of the tool body 504 can be ensured, thereby ensuring the accuracy of the machining process.

[0024] Example 3: Reference Figure 7 , Figure 8 , Fig. 9 , Fig.12 The multifunctional composite tool quick switching device for a vertical turning, milling and grinding composite machine tool is basically the same as Example 1. Furthermore, an electric telescopic rod 7 is fixedly connected to the connecting seat 5, and a ring 701 is fixedly connected to the output end of the electric telescopic rod 7. The ring 701 is sleeved on the tool body 504, and a cleaning brush 702 is provided on the inner wall of the ring 701.

[0025] A sleeve 703 is fixedly connected to the connecting seat 5, a piston disc 704 is slidably connected inside the sleeve 703, a connecting rod 705 is fixedly connected to the piston disc 704, one end of the connecting rod 705 passes through the lower end of the sleeve 703 and is fixedly connected to the collar 701, an air storage chamber is provided in the sleeve 703 below the piston disc 704, an air inlet pipe 706 and an air outlet pipe 707 connected to the air storage chamber are provided on the sleeve 703, a hollow cavity 708 is opened on the collar 701, a plurality of nozzles 709 connected to the hollow cavity 708 are equidistantly arranged on the inner wall circumference of the collar 701, and one end of the air outlet pipe 707 away from the air storage chamber is connected to the hollow cavity 708.

[0026] When the tool body 504 completes the processing task and needs to clean the surface of the tool body 504, the electric telescopic rod 7 is started, the output end of the electric telescopic rod 7 is extended, and the collar 701 is driven to move along the tool body 504. The cleaning brush 702 on the inner wall of the collar 701 wipes and cleans the surface of the tool body 504, so that the impurities and debris on the surface of the tool body 504 are removed, so that the surface of the tool body 504 is kept clean, the service life of the tool is extended, and the impurities and debris are prevented from affecting the processed workpiece, thereby improving the processing quality; At the same time, when the electric telescopic rod 7 drives the ring 701 to move, the ring 701 drives the piston disc 704 to slide in the sleeve 703 through the connecting rod 705. When the piston disc 704 slides downward, the gas in the air storage chamber is compressed, and the gas enters the hollow cavity 708 of the ring 701 through the air outlet pipe 707, and then is sprayed out from the nozzle 709, so that it blows and cleans the tool body 504, which can more effectively remove fine impurities and debris on the surface of the tool body 504, and cooperates with the cleaning brush 702 to improve the cleaning effect. After cleaning, the electric telescopic rod 7 contracts to return the ring 701 to its initial position.

[0027] It should be noted that the air outlet pipe 707 is a stretchable and shrinkable hose, so the air outlet pipe 707 will not interfere with the up and down movement of the ring 701, and both the air inlet pipe 706 and the air outlet pipe 707 are provided with a one-way valve.

[0028] Example 4: Reference Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.12 The multifunctional composite tool quick switching device for a vertical turning, milling and grinding composite machine tool is basically the same as Example 1, and further, a liquid suction chamber is provided in the sleeve 703 above the piston disc 704, and a liquid suction pipe 801 and a liquid discharge pipe 802 connected to the liquid suction chamber are provided on the sleeve 703. A liquid storage chamber 8 is opened on the machine tool body 1, and the end of the liquid suction pipe 801 away from the liquid suction chamber is connected to the liquid storage chamber 8, and the end of the liquid discharge pipe 802 away from the liquid suction chamber is connected to the hollow cavity 708.

[0029] After the surface of the tool body 504 is cleaned, the collar 701 is at the lower end of the tool. At this stage, impurities and debris on the surface of the tool have been removed by the previous cleaning operations such as gas blowing and wiping with the cleaning brush 702. Then, the operator or the machine tool control system issues a command to start the electric telescopic rod 7, and the electric telescopic rod 7 starts to drive the collar 701 to move upward and start the reset process. Since the collar 701 is connected to the piston disc 704 through the connecting rod 705, the upward movement of the collar 701 drives the piston disc 704 to slide upward in the sleeve 703 synchronously. As the piston disc 704 slides upward, the space in the liquid suction chamber is compressed and the pressure increases. Under the action of pressure, the rust-proof lubricating maintenance liquid stored in the liquid suction chamber flows into the hollow cavity 708 of the collar 701 through the drain pipe 802, and then is sprayed onto the surface of the tool body 504 from the nozzles 709 evenly distributed on the circumference; At the same time, as the collar 701 continues to move upward, the cleaning brush 702 on the inner wall of the collar 701 is in full contact with the surface of the tool body 504. As the collar 701 moves, the cleaning brush 702 evenly brushes the anti-rust lubricating maintenance liquid just sprayed on the surface of the tool, so that the maintenance liquid can cover all parts of the tool, including the blade, the blade body, etc., ensuring that the maintenance liquid forms a uniform protective film on the surface of the tool, effectively isolating the contact between air, moisture and corrosive substances generated during the processing and the surface of the tool, thereby significantly reducing the risk of rust and corrosion of the tool. At the same time, the lubricating component can reduce the friction resistance of the tool during the cutting process and reduce the wear rate of the tool. The uniform application of the maintenance liquid further enhances the protection and lubrication effect, so that the service life of the tool is greatly extended, the replacement frequency of the tool is reduced, and the purchase cost of the tool is reduced; At the same time, as the piston disc 704 slides upward in the sleeve 703, the volume of the air storage chamber gradually increases. The increase in volume causes the pressure in the air storage chamber to decrease, forming a negative pressure. At this time, the external gas is sucked into the air storage chamber through the air inlet pipe 706 under the action of the pressure difference, and the gas is reserved for the next tool cleaning.

[0030] When cleaning the surface of the tool body 504, as the piston disc 704 slides downward in the sleeve 703, the volume of the liquid suction chamber gradually increases. The increase in volume causes the pressure in the liquid suction chamber to decrease, forming a negative pressure. At this time, under the action of the pressure difference, the maintenance chamber in the liquid storage chamber 8 is sucked into the liquid suction chamber through the liquid suction tube 801, thereby reserving maintenance fluid for subsequent tool maintenance.

[0031] It should be noted that the drain pipe 802 is a stretchable hose, so the drain pipe 802 will not interfere with the up and down movement of the ring 701. Both the suction pipe 801 and the drain pipe 802 are provided with a one-way valve.

[0032] Example 5: Reference Figure 1 , Figure 2 , a multifunctional composite tool quick switching device for a vertical lathe-milling and grinding composite machine tool, which is basically the same as that of Example 1, and further, a collecting tank connected to the liquid storage chamber 8 is provided on the machine tool body 1, the collecting tank is concave downward, and a filter screen 803 is provided in the collecting tank; When the tool body 504 completes the processing task, the anti-rust lubricating maintenance liquid is sprayed onto the surface of the tool body 504 through the nozzle 709 to maintain the tool body 504. Under the action of gravity, the maintenance liquid will flow downward along the surface of the tool body 504, and then drip into the collecting groove provided on the machine tool body 1. Since the collecting groove is concave downward, the maintenance liquid can be effectively gathered, so that when the maintenance liquid flows through the collecting groove, it will pass through the filter net 803 provided therein, so that it can intercept the impurities and debris therein and only allow the maintenance liquid to pass through. Then, the clean maintenance liquid after filtration passes through the channel connected to the collecting groove and flows back to the liquid storage chamber 8, thereby realizing the recovery and recycling of the maintenance liquid, reducing the consumption and replenishment frequency of the maintenance liquid, and greatly reducing the production cost.
