[0002] Power turrets are used on CNC machine tools to process complex parts. The drive form is to transmit the motor power to various tools on the power turret through a transmission gear set to perform turning, milling, drilling and other processing on the workpiece. To meet different processing requirements, the tools are switched by rotating the cutter head.

[0003] Traditional power turrets mostly use multiple sets of gear transmission for power output, which results in large power loss, low processing efficiency, high repair and maintenance costs, and a relatively complex transmission mechanism. The turrets have large cumulative errors during the production process, which seriously affects processing accuracy and product quality. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a direct-drive power turret, which solves the problem in the prior art that the transmission mechanism of the turret is relatively complex, resulting in large cumulative errors in the production process of the turret, seriously affecting the processing accuracy and product quality.

[0005] The technical problem to be solved by the present invention is achieved by adopting the following technical scheme: a direct-drive power turret, comprising a turret support body, an adjustment block, a turret main body, an inner rotating block, a direct-drive motor, an assembly tool holder, a tool, an adjustment structure, a driving structure and a connecting structure, wherein the interior of the turret support body is a hollow structure, the adjustment structure is arranged on the outer side of the turret support body, the adjustment block is dynamically connected to the adjustment structure, the driving structure is arranged on the side of the adjustment block facing the interior of the turret support body, the turret main body is fixed on the side of the adjustment block away from the adjustment structure, the interior of the turret main body is a hollow setting to form a direct-drive cavity, the inner rotating block is rotatably arranged in the direct-drive cavity and the inner rotating block is connected to the tool The turret body is coaxially arranged, the direct drive motor is fixed on the inner rotating block, the direct drive motor is provided with an output end facing the opening direction of the assembly hole, the driving structure is dynamically connected with the inner rotating block, the outer curved surface of the turret body is provided with a plurality of assembly holes in an equiangular circular array, the assembly holes are connected with the direct drive cavity, the assembly tool holder is detachably fixed on the turret body and aligned with the assembly hole opening, a connecting structure is provided on the side of the assembly tool holder facing the assembly hole, the tool rotation is arranged on the assembly tool holder, the tool and the output end of the direct drive motor are dynamically connected through the connecting structure, the adjustment structure is the same as driving the adjustment block to move linearly, and the driving structure is used to drive the inner rotating block to rotate on a fixed axis.

[0006] By adopting the above technical solution, the vertical position of the turret body is adjusted through the adjustment structure, and the position of the output end of the direct-drive motor is adjusted through the driving structure, so that the output end of the direct-drive motor can be aligned with any assembly hole. When the assembly tool holder is connected to the direct-drive motor power through the connecting structure, the direct-drive motor is started and drives the tool to rotate through the connecting structure, so that the tool can process and cut the workpiece. The tool is driven by the direct-drive motor, which eliminates many transmission mechanisms such as gear transmission and belt transmission, and greatly improves the output efficiency and operation stability of the direct-drive motor.

[0007] The present invention is further configured as follows: the adjustment structure includes an adjusting motor, a pulley group, a screw rod, an internal thread block, a slide rail and a slider, two slide rails are provided and are fixedly arranged side by side on the outer side of the turret support body, the slider is slidably arranged on the slide rail, the adjustment block is fixedly connected to the slider, the adjustment motor is fixedly arranged inside the turret support body, the screw rod is rotatably arranged inside the turret support body, the axial direction of the screw rod is the same as the extension direction of the slide rail, the internal thread block is sleeved on the screw rod and threadedly connected to the screw rod, the internal thread block is fixedly connected to the adjustment block, the pulley group is arranged on the turret support body and the screw rod and the adjusting motor are dynamically connected through the pulley group.

[0008] By adopting the above technical solution, after the adjustment motor is started, the screw rod is driven to rotate through the pulley group. Since the adjustment block is fixedly connected to the slider, and the slide rail is fixedly connected to the turret support body, the adjustment block can only slide along the extension direction of the slide rail following the slider. At this time, the internal thread block cannot rotate along with the screw rod. During the rotation of the screw rod, the internal thread block moves along the axial direction of the screw rod due to the effect of the thread structure, thereby driving the adjustment block to move along the axial direction of the screw rod, and then driving the turret body to move along the axial direction of the screw rod, thereby achieving the purpose of adjusting the vertical position of the turret body.

[0009] The present invention is further configured as follows: the driving structure includes a driving motor and a gear set, the driving motor is fixedly arranged on the side of the adjustment block facing the turret support body, the interior of the adjustment block is hollow, the end of the inner rotating block away from the turret body extends to the interior of the adjustment block, the gear set is arranged inside the adjustment block, and the gear set connects the driving motor with the inner rotating block power.

[0010] By adopting the above technical solution, since the driving motor and the gear set are arranged on the adjusting block, they can follow the movement of the adjusting block during the movement of the adjusting block. At the same time, after the driving motor is started, the gear set is used to drive the fixed axis of the inner rotating block to rotate, thereby driving the rotation of the direct drive motor, thereby achieving the purpose of adjusting the direction of the output end of the direct drive motor, so that the user can install the assembly tool holder in the assembly holes at different positions under random working conditions, and the direct drive motor can be connected to the assembly tool holder power through the connecting structure.

[0011] The present invention is further configured as follows: the connecting structure includes a connecting shaft and a transmission member, the connecting shaft is rotatably connected to the assembly tool seat and the end of the connecting shaft extends into the interior of the assembly tool seat, one end of the connecting shaft extending into the interior of the assembly tool seat is connected to the transmission member, the connecting shaft and the tool are dynamically connected via the transmission member, and one end of the connecting shaft away from the assembly tool seat extends into the assembly hole and is dynamically connected to the output end of the direct drive motor.

[0012] By adopting the above technical solution, when the rotating axis of the tool is perpendicular to the rotating axis of the connecting shaft, the two are connected by a transmission member, and when the connecting shaft rotates, the tool is driven to rotate by the transmission member; when the rotating axis of the tool and the rotating axis of the connecting shaft are coaxially arranged, the connecting shaft can be directly connected to the tool, and when the connecting shaft rotates, the tool is directly driven to rotate, so that the tool can adapt to different installation positions under different working conditions, further ensuring the output efficiency of the direct-drive motor while adapting to a variety of working conditions, thereby improving the adaptability of the turret.

[0013] The present invention is further configured as follows: a nozzle is fixedly arranged on one side of the tool assembly seat where the tool is arranged, the end of the nozzle extends toward the direction of the tool, and a liquid supply connector is fixedly arranged on the tool assembly seat, and the liquid supply connector is connected to the nozzle.

[0014] By adopting the above technical solution, the liquid supply connector is connected to the external liquid supply device, the coolant is pumped in through the liquid supply connector, and then sprayed toward the tool through the nozzle, thereby achieving the purpose of cooling the cutting workpiece and the tool.

[0015] The present invention is further configured as follows: an airtight groove is provided around the side of the inner side of the assembly hole away from the direct drive cavity, a flexible shielding layer is fixedly provided at the opening of the airtight groove, the flexible shielding layer closes the airtight groove, the airtight groove and the flexible shielding layer surround to form an airtight space, the airtight space is filled with inert gas, an elastic sheet is fixedly provided around the part of the outer curved surface of the connecting shaft extending into the assembly hole, the elastic sheet is located at the opening of the airtight groove and abuts against the flexible shielding layer, after the elastic sheet abuts against the flexible shielding layer, the flexible shielding layer is pressed into the interior of the airtight groove and the elastic sheet and the airtight groove form a clamping structure.

[0016] By adopting the above technical solution, when the connecting shaft is inserted into the assembly hole and the assembly tool holder has not yet been fixedly connected to the turret body, the elastic sheet moves to the opening of the airtight groove. Under the elastic force of the elastic sheet, the elastic sheet presses the flexible shielding layer into the airtight groove. At this time, the airtight groove forms a clamping structure for the elastic sheet. At this time, the connecting shaft cannot move axially, thereby ensuring the stability of the assembly tool holder during installation.

[0017] The present invention is further configured as follows: the inner side of the assembly hole close to the direct drive chamber side converges toward the axis to form a stepped structure, a secondary pressure chamber is opened around the assembly hole at the stepped structure of the assembly hole inside the turret body, a pressure plate is slidably arranged in the secondary pressure chamber, one end of the pressure plate is located in the secondary pressure chamber and slidingly fits with the inner wall of the secondary pressure chamber, the other end of the pressure plate extends axially along the assembly hole to the inner side of the assembly hole through the stepped structure of the assembly hole, the end of the pressure plate located on the inner side of the assembly hole can abut against the connecting shaft, and after the pressure plate abuts against the connecting shaft, the pressure plate is pressed into the secondary pressure chamber by the connecting shaft.

[0018] The present invention is further configured as follows: a main pressure chamber is opened on the side of the secondary pressure chamber away from the airtight groove, the main pressure chamber is arranged around the turret body with the axis of the turret body as the axis, the secondary pressure chamber is connected with the main pressure chamber, an intermediate channel is arranged between the airtight groove and the main pressure chamber, and the gas environment of the airtight groove, the secondary pressure chamber, the intermediate channel and the main pressure chamber are connected.

[0019] By adopting the above technical scheme, when the end of the connecting shaft is inserted into the assembly hole, the connecting shaft abuts against one end of the pressure plate extending into the assembly hole. At this time, the pressure plate is pressed by the connecting shaft to move toward the direction of the direct drive chamber. At this time, the pressure plate pushes the gas in the secondary pressure chamber into the main pressure chamber, the air pressure in the main pressure chamber increases, and the elastic sheet presses the flexible shielding layer into the airtight groove, thereby increasing the air pressure in the airtight groove. Since the main pressure chamber is connected to the airtight groove through the intermediate channel, the air pressure in the main pressure chamber is further increased by the above two actions. Therefore, the air pressure in the airtight groove on the inner side of the remaining assembly hole increases at this time, so that the flexible shielding layer further expands toward the direction of the axis of the assembly hole, thereby blocking the opening of the assembly hole. When the opening of the assembly hole becomes smaller, external foreign matter such as cutting chips cannot enter the assembly hole, and then foreign matter cannot enter the direct drive chamber, thereby avoiding foreign matter from interfering with the rotation of the inner rotating block, improving the stability of the output end adjustment step of the direct drive motor, and facilitating the normal operation of the turret.

[0020] The beneficial effects of the present invention are as follows: the vertical position of the turret body is adjusted by the adjustment structure, and the position of the output end of the direct-drive motor is adjusted by the driving structure, so that the output end of the direct-drive motor can be aligned with any assembly hole. When the assembly tool holder is connected to the power of the direct-drive motor through the connecting structure, the direct-drive motor starts and drives the tool to rotate through the connecting structure, so that the tool can process and cut the workpiece. The tool is driven by the direct-drive motor, which eliminates many transmission mechanisms such as gear transmission and belt transmission, and greatly improves the output efficiency and operation stability of the direct-drive motor.

A connecting structure is provided on the side of the assembly tool seat 26 facing the assembly hole 30, and the tool 28 is rotatably provided on the assembly tool seat 26. The tool 28 is dynamically connected to the output end of the direct drive motor 23 through the connecting structure. The adjustment structure is the same as the linear motion of the driving adjustment block 19, and the driving structure is used to drive the fixed axis rotation of the inner rotating block 22.

[0033] like Figure 3-4As shown, the adjustment structure includes an adjusting motor 11, a pulley group 12, a screw rod 13, an internal thread block 14, a slide rail 17 and a slider 18. Two slide rails 17 are provided and are fixedly arranged side by side on the outer side of the turret support body 10. The slider 18 is slidably arranged on the slide rail 17. The adjustment block 19 is fixedly connected to the slider 18. The adjusting motor 11 is fixedly arranged inside the turret support body 10. The screw rod 13 is rotatably arranged inside the turret support body 10. The axial direction of the screw rod 13 is the same as the extension direction of the slide rail 17. The internal thread block 14 is sleeved on the screw rod 13 and is threadedly connected to the screw rod 13. The internal thread block 14 is fixedly connected to the adjustment block 19. The pulley group 12 is arranged on the turret support body 10 and the screw rod 13 is dynamically connected to the adjusting motor 11 through the pulley group 12. The driving structure includes a driving motor 15 and a gear set 16. The driving motor 15 is fixedly arranged on a side of the adjustment block 19 facing the turret support body 10. The interior of the adjustment block 19 is hollow. The end of the inner rotating block 22 away from the turret body 20 extends to the inside of the adjustment block 19. The gear set 16 is arranged inside the adjustment block 19. The gear set 16 connects the driving motor 15 with the inner rotating block 22. The connecting structure includes a connecting shaft 25 and a transmission member. The connecting shaft 25 is rotatably connected to the assembly tool seat 26 and the end of the connecting shaft 25 extends to the inside of the assembly tool seat 26. The end of the connecting shaft 25 extending to the inside of the assembly tool seat 26 is connected to the transmission member. The connecting shaft 25 and the tool 28 are connected to each other through the transmission member. The end of the connecting shaft 25 away from the assembly tool seat 26 extends into the assembly hole 30 and is connected to the output end of the direct drive motor 23. The transmission member includes but is not limited to a group of helical gears, a group of worm gears, etc.

[0034] like Figure 4 As shown, a nozzle 29 is fixedly arranged on one side of the assembly tool holder 26 where the tool 28 is arranged, and the end of the nozzle 29 extends toward the direction of the tool 28. A liquid supply connector 27 is fixedly arranged on the assembly tool holder 26, and the liquid supply connector 27 is connected to the nozzle 29. The liquid supply connector 27 is connected to an external liquid supply device, and the coolant is pumped in through the liquid supply connector 27, and then sprayed toward the tool 28 through the nozzle 29, thereby achieving the purpose of cooling the cutting workpiece and the tool.

[0035] like Figure 4-8As shown, an airtight groove 32 is provided around the side of the inner side of the assembly hole 30 away from the direct drive cavity 21, and a flexible shielding layer 31 is fixedly provided at the opening of the airtight groove 32, and the flexible shielding layer 31 closes the airtight groove 32. The airtight groove 32 and the flexible shielding layer 31 surround and form an airtight space, and the airtight space is filled with an inert gas. An elastic sheet 35 is fixedly provided around the part of the outer curved surface of the connecting shaft 25 extending into the assembly hole 30, and the elastic sheet 35 is located at the opening of the airtight groove 32 and abuts against the flexible shielding layer 31. After the elastic sheet 35 abuts against the flexible shielding layer 31, the flexible shielding layer 31 is pressed into the interior of the airtight groove 32, and the elastic sheet 35 and the airtight groove 32 form a clamping structure. The inner side of the assembly hole 30 close to the direct drive chamber 21 is converged toward the axis to form a stepped structure, and a secondary pressure chamber 33 is opened around the assembly hole 30 at the stepped structure of the assembly hole 30 inside the turret body 20, and a pressure plate 34 is slidably arranged in the secondary pressure chamber 33, one end of the pressure plate 34 is located in the secondary pressure chamber 33 and slides in contact with the inner wall of the secondary pressure chamber 33, and the other end of the pressure plate 34 extends axially along the assembly hole 30 to the inner side of the assembly hole 30 through the stepped structure of the assembly hole 30, and the end of the pressure plate 34 located on the inner side of the assembly hole 30 can abut against the connecting shaft 25, and after the pressure plate 34 abuts against the connecting shaft 25, it is pressed into the secondary pressure chamber 33 by the connecting shaft 25. A main pressure chamber 37 is provided on the side of the secondary pressure chamber 33 away from the airtight groove 32. The main pressure chamber 37 is arranged around the turret body 20 with the axis of the turret body 20 as the axis. The secondary pressure chamber 33 is connected with the main pressure chamber 37. An intermediate channel 36 is provided between the airtight groove 32 and the main pressure chamber 37. The gas environments of the airtight groove 32, the secondary pressure chamber 33, the intermediate channel 36 and the main pressure chamber 37 are connected.

[0036] The turret body 20 adjusts the vertical position through the adjustment structure, and at the same time adjusts the position of the output end of the direct drive motor 23 through the driving structure, so that the output end of the direct drive motor 23 can be aligned with any assembly hole 30. When the assembly tool holder 26 is connected to the direct drive motor 23 through the connecting structure, the direct drive motor 23 starts and drives the tool 28 to rotate through the connecting structure, so that the tool 28 can process and cut the workpiece. The tool 28 is driven by the direct drive motor 23, which eliminates many transmission mechanisms such as gear transmission and belt transmission, and greatly improves the output efficiency and operation stability of the direct drive motor 23.

[0037] After the adjustment motor 11 is started, the screw rod 13 is driven to rotate through the pulley group 12. Since the adjustment block 19 is fixedly connected to the slider 18, and the slide rail 17 is fixedly connected to the turret support body 10, the adjustment block 19 can only slide along the extension direction of the slide rail 17 following the slider 18. At this time, the internal thread block 14 cannot rotate along with the screw rod 13. During the rotation of the screw rod 13, due to the action of the threaded structure, the internal thread block 14 moves axially along the screw rod 13, thereby driving the adjustment block 19 to move axially along the screw rod 13, and then driving the turret body 20 to move axially along the screw rod 13, thereby achieving the purpose of adjusting the vertical position of the turret body 20.

[0038] Since the driving motor 15 and the gear set 16 are arranged on the adjusting block 19, they can follow the adjusting block 19 during the movement of the adjusting block 19. At the same time, after the driving motor 15 is started, the fixed axis of the inner rotating block 22 is driven to rotate through the gear set 16, thereby driving the rotation of the direct drive motor 23, so as to achieve the purpose of adjusting the direction of the output end of the direct drive motor 23, so that the user can install the assembly tool holder 26 in the assembly hole 30 at different positions under random working conditions, and the direct drive motor 23 can be connected to the assembly tool holder 26 through the connecting structure. When the rotation axis of the tool 28 is perpendicular to the rotation axis of the connecting shaft 25, the two are connected through a transmission member, and the tool 28 is driven to rotate through the transmission member when the connecting shaft 25 rotates. When the rotation axis of the tool 28 is coaxially arranged with the rotation axis of the connecting shaft 25, the connecting shaft 25 can be directly connected to the tool 28, and the tool 28 is directly driven to rotate when the connecting shaft 25 rotates, so that the tool 28 can adapt to different installation positions under different working conditions, further ensuring the output efficiency of the direct drive motor 23 while adapting to a variety of working conditions, and improving the adaptability of the turret.

[0039] When the connecting shaft 25 is inserted into the assembly hole 30 and the assembly tool holder 26 has not yet been fixedly connected to the turret body 20, the elastic sheet 35 moves to the opening of the airtight groove 32. Under the elastic force of the elastic sheet 35, the elastic sheet 35 presses the flexible shielding layer 31 into the airtight groove 32. At this time, the airtight groove 32 forms a clamping structure for the elastic sheet 35. At this time, the connecting shaft 25 cannot move axially, thereby ensuring the stability of the assembly tool holder 26 during installation. When the end of the connecting shaft 25 is inserted into the assembly hole 30, the connecting shaft 25 abuts against one end of the pressure plate 34 extending into the assembly hole 30. At this time, the pressure plate 34 is pressed by the connecting shaft 25 to move toward the direction of the direct drive chamber 21. At this time, the pressure plate 34 pushes the gas in the auxiliary pressure chamber 33 into the main pressure chamber 37, and the air pressure in the main pressure chamber 37 increases. The elastic sheet 35 presses the flexible shielding layer 31 into the airtight groove 32, which increases the air pressure in the airtight groove 32. Since the main pressure chamber 37 is connected to the airtight groove 32 through the intermediate channel 36, the main pressure chamber 37 is increased by the above two actions. The air pressure in the force chamber 37 is further increased, and therefore the air pressure in the airtight groove 32 on the inner side of the remaining assembly hole 30 is increased at this time, so that the flexible shielding layer 31 is further expanded toward the axis of the assembly hole 30, thereby blocking the opening of the assembly hole 30. When the opening of the assembly hole 30 becomes smaller, external foreign matter such as cutting chips cannot enter the assembly hole 30, and foreign matter cannot enter the direct drive chamber 21, thereby preventing foreign matter from interfering with the rotation of the inner rotating block 22, thereby improving the stability of the output end adjustment step of the direct drive motor 23, and facilitating the normal operation of the turret.

[0040] like Fig. 9 As shown, the interior of the inner rotating block 22 is arranged in a cavity shape, and the direct drive motor 23 is arranged in the inner cavity of the inner rotating block 22. The direct drive motor 23 includes a motor housing 42 and a motor shaft 43. The end of the motor shaft 43 passes through the inner rotating block 22 and extends into the direct drive cavity 21. The connection between the motor shaft 43 and the inner rotating block 22 is sealed. There is a gap between the motor housing 42 and the inner wall of the cavity of the inner rotating block 22 and a cooling channel 44 is formed. The cooling channel 44 is filled with coolant, and the coolant can cool the direct drive motor 23 during operation. A signal feedback module 45 is fixedly arranged in the cavity of the inner rotating block 22. The signal feedback module 45 is a waterproof structure. The signal feedback module 45 is used to transmit the operation data of the motor housing 42.

[0041] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention.
