[0028] 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.
[0029] Example 1
[0030] Please see Figure 1 -and Figure 6 This is the first embodiment of the present utility model. This embodiment provides a built-in motor turret, including a housing 1 and a tool holder. The housing 1 provides an installation reference and structural support for each component. The tool holder, as the component that directly performs machining, is the core carrier for realizing the machining function. Together, they constitute the basic framework of the turret.
[0031] The servo motor 8 is mounted on the housing 1. The output shaft of the servo motor 8 is connected to a pinion A4. The servo motor 8 is fixed on the housing 1 to ensure the installation stability of the power source. Its output shaft is connected to the pinion A4 to provide initial power transmission for tool changing of the tool head. The efficient output of power is achieved through gear transmission, laying the foundation for subsequent tool head rotation.
[0032] The large gear B5 meshes with the small gear A4, and the cutter head 2 is mounted on the large gear B5. The meshing transmission between the small gear A4 and the large gear B5 realizes the transmission of power from the servo motor 8 to the cutter head 2. The speed requirement of the cutter head 2 for tool changing is adapted by the gear reduction (or speed increase). The cutter head 2 is mounted on the large gear B5 and can rotate synchronously with the large gear B5, thereby realizing the tool changing action of the cutter head.
[0033] The fixed gear plate 7 is installed on the housing 1. The fixed gear plate 7 is fixed on the housing 1 and serves as the fixed reference of the locking mechanism. It provides a meshing object for the sliding gear plate 6 and ensures the stability of the cutter head when locking. It is a key component for achieving reliable positioning of the cutter head 2 during machining.
[0034] The sliding gear 6, which can be hydraulically driven to mesh with the large gear B5 and the fixed gear 7 to lock the cutter head 2, has sealing cylinders at its front and rear positions. The sliding gear 6 achieves meshing with the large gear B5 and the fixed gear 7 through hydraulic drive, which can quickly and reliably lock the cutter head 2 and ensure the stability of the cutter head during machining. The front and rear sealing cylinders ensure pressure sealing during hydraulic drive, prevent oil leakage, ensure effective transmission of hydraulic drive force, and improve the reliability of the locking action.
[0035] The built-in motor 3 drives the tool holder directly. The direct drive design reduces the intermediate transmission links of the traditional external motor, reduces energy loss, improves transmission efficiency, and enables the tool holder to rotate at high speed, meeting the needs of high-speed milling.
[0036] In this embodiment, preferably, the rear end of the sliding gear disk 6 is connected to an oil pipe A10, and the front end is connected to an oil pipe B11. By controlling the oil inlet of oil pipe A10 and the oil outlet of oil pipe B11, the sliding gear disk 6 is driven to mesh with the fixed gear disk 7 and the large gear B5. Through the oil inlet and outlet control of oil pipes A10 and B11, the precise movement of the sliding gear disk 6 is achieved, ensuring its reliable meshing with the fixed gear disk 7 and the large gear B5, improving the controllability and stability of the locking action, and making the operation convenient and responsive.
[0037] In this embodiment, preferably, the built-in motor 3 is provided with a tool holder guide groove 31 for aligning the flat part of the input shaft of the tool holder with the flat groove of the motor shaft of the built-in motor 3 during tool changing. The tool holder guide groove 31 plays a positioning and guiding role during tool changing, ensuring that the flat part of the input shaft of the tool holder is precisely aligned with the flat groove of the motor shaft of the built-in motor 3, avoiding shaft docking deviation during tool changing, improving tool changing efficiency and accuracy, and ensuring reliable transmission between the built-in motor 3 and the tool holder.
[0038] In this embodiment, preferably, it also includes a water shaft 9 and a water shaft mounting base 93. The water shaft 9 and the water shaft mounting base 93 form a piston-like structure. A sealing ring 91 is provided at the front end of the water shaft 9. The piston-like structure of the water shaft 9 and the water shaft mounting base 93 can use water pressure to drive the water shaft 9 to move and achieve the pressing of the cutter head 2. The sealing ring 91 at the front end ensures the sealing effect of the cooling water, prevents water leakage from affecting the operation of the equipment, and improves the reliability of the cooling system.
[0039] In this embodiment, preferably, a pressure cap 92 is also included, which is connected to the water shaft mounting base 93 by screws.
[0040] In this embodiment, preferably, the water shaft mounting base 93 is provided with a high-pressure cooling water inlet 930. During machining, high-pressure cooling water enters through the high-pressure cooling water inlet 930, pushing the water shaft 9 forward to press against the cutter head 2. When changing tools, the water supply is stopped, the pressing force of the water shaft 9 is eliminated, and the high-pressure cooling water inlet 930 provides an input channel for cooling water. During machining, the high-pressure water drives the water shaft 9 to press against the cutter head 2, enhancing the stability of the cutter head and simultaneously achieving the cooling function. When changing tools, the water supply is stopped to eliminate the pressing force, avoiding affecting the rotation of the cutter head. This achieves coordinated control of cooling and cutter head movement, improving the coordination of equipment operation.
[0041] In this embodiment, preferably, the cutter head 2 has a water channel 21 inside, and the water channel 21 is connected to the tool holder. The water channel 21 inside the cutter head 2 guides cooling water from the water shaft 9 to the tool holder, realizing direct cooling of the machining part, effectively reducing the temperature of the tool holder and the tool, ensuring the stability of the machining process, extending the tool life, and improving the machining accuracy.
[0042] Example 2
[0043] Please see Figures 1-6 This is the second embodiment of the present invention, which is based on the previous embodiment, but differs in that:
[0044] An extension cylinder 920 is located at the bottom of the pressure cap 92. A slot 931 is provided on the water shaft mounting base 93 for the extension cylinder 920 to be inserted. A sleeve 13 is installed inside the slot 931. A washer 130 is located on the inner wall of the sleeve 13 and can abut against the extension cylinder 920. The connection and disassembly of the pressure cap 92 and the water shaft mounting base 93 facilitates maintenance. The cooperation between the extension cylinder 920 and the slot 931 enables the positioning and installation of the pressure cap 92. The sleeve 13 and the washer 130 enhance the sealing and stability of the connection between the pressure cap 92 and the water shaft mounting base 93. The abutting action of the washer 130 can buffer vibration and improve the overall robustness of the structure. The height of the sleeve 13 is two-thirds of the depth of the slot 931. The height of the washer 130 is less than the height of the sleeve 13. The sleeve 13 provides support and protection for the washer 130, preventing the washer 130 from being over-compressed and damaged, and ensuring the stability and durability of the connection structure.
[0045] The working principle and usage process of this utility model: all components of the turret are in the initial position, the sliding toothed disc 6 is not engaged with the fixed toothed disc 7 and the large gear B5, the cutter disc 2 can rotate freely, the built-in motor 3 is in a stopped state, the water shaft 9 is not subjected to the thrust of high-pressure cooling water and does not press the cutter disc 2.
[0046] The control system receives preset machining programming instructions and determines the required machining process and the corresponding tool holder;
[0047] The control system starts the servo motor 8 according to the command. The output shaft of the servo motor 8 drives the pinion A4 to rotate. The pinion A4 meshes with the large gear B5, which in turn drives the cutter head 2 fixed on the large gear B5 to rotate, so that the target tool holder moves to the machining position.
[0048] During the tool changing process, the tool holder guide groove 31 on the built-in motor 3 ensures that the input shaft flat position of the tool holder is precisely aligned with the motor shaft flat groove of the built-in motor 3;
[0049] After the tool change is completed, the control system controls the oil pipe A10 to enter the oil and the oil pipe B11 to exit the oil. The sliding gear plate 6 moves forward under the hydraulic thrust of the rear sealing cylinder and meshes with the fixed gear plate 7 and the large gear B5 to lock the tool plate 2 and ensure the stability during machining.
[0050] After the cutter head 2 is locked, the control system drives the built-in motor 3 to start. The built-in motor 3 directly drives the cutter holder to rotate at high speed and begins to perform the machining operation.
[0051] Meanwhile, high-pressure cooling water enters through the high-pressure cooling water inlet 930 on the water shaft mounting base 93, pushing the water shaft 9 forward. The sealing ring 91 at the front end of the water shaft 9 ensures a leak-proof seal, and the water shaft 9 presses against the cutter head 2. Cooling water is transported to the cutter holder through the water channel 21 inside the cutter head 2 to cool the machining area.
[0052] After the current processing step is completed, the control system controls the built-in motor 3 to stop rotating, and the tool holder stops working;
[0053] The supply of high-pressure cooling water is stopped, the clamping force of the water shaft 9 moving forward is eliminated, and it no longer clamps the cutter head 2;
[0054] The control system controls oil pipe A10 to release oil and oil pipe B11 to enter oil. Under the hydraulic action of the front sealing cylinder, the sliding gear 6 moves backward, disengaging from the fixed gear 7 and the large gear B5, and the cutter head 2 is unlocked.
[0055] Although embodiments of the present invention have been shown and described in detail above, 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.
