Description

Technical Field

[0002] A turning center is a highly efficient processing equipment that combines the functions of a CNC lathe and a special milling machine or drilling machine. The power tool holder is an important component of the turning center. When complex processing tasks need to be completed, traditional CNC lathes usually require secondary clamping for milling, drilling and other processes after completing the turning process. This not only increases the error of the workpiece, but also reduces the processing efficiency. The speed-increasing power tool holder can complete multiple processing tasks in one clamping, especially for workpieces that are mainly turned and supplemented by a small amount of milling or drilling, which significantly improves processing efficiency and accuracy.

DETAILED DESCRIPTION

[0071] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0072] like Figures 1 to 8 As shown, this embodiment proposes a turning center speed-increasing power tool holder, including a tool holder frame 1, the tool holder frame 1 is provided with a feed area and a drive area, and also includes a sliding frame 2, a supporting frame 3, a bearing 4, a mounting ring 5, a feed assembly and a spray assembly. The sliding frame 2 is slidably installed inside the feed area, the supporting frame 3 is fixedly installed at the working end of the sliding frame 2, the bearing 4 is fixedly installed inside the supporting frame 3, the bearing 4 can preferably adopt a tapered roller bearing 4, the mounting ring 5 is fixedly installed at one end of the supporting frame 3 away from the sliding frame 2, and the feed assembly is installed inside the drive area for carrying The movable sliding frame 2 moves, and the feeding assembly includes a slide groove 6, a first motor 7, a screw rod 8, a sliding frame 9, a feed nut 10 and a guide part. A slide groove 6 is opened at the bottom of the driving area, and the slide groove 6 is located on the upper part of the sliding frame 2. The first motor 7 is fixedly installed inside the driving area, and the screw rod 8 is rotatably installed inside the driving area. The sliding frame 9 is slidably installed on the slide groove 6, and the sliding frame 9 is fixedly connected to the sliding frame 2. The feed nut 10 is threadedly sleeved on the screw rod 8, and the feed nut 10 is fixedly connected to the sliding frame 9. The guide part is installed inside the feeding area to guide the sliding direction of the sliding frame 2.

[0073] In order to enable milling, drilling, tapping and other processes to be carried out immediately after the workpiece is turned, a dynamic tool holder is required to realize this integrated processing method, thereby shortening the processing time, reducing the transfer of workpieces between different machine tools, reducing the time for loading and unloading and changing machines, and reducing the chance of human tolerance.

[0074] Specifically, when using a power tool holder, first install the required tool, then push the tool holder frame 1 to move on the lathe until the tool holder frame 1 is moved to the processing position, and then the workpiece can be processed by the tool. During the processing, in order to increase the processing stroke, the first motor 7 is started, and the first motor 7 drives the screw rod 8 to rotate, and the screw rod 8 drives the feed nut 10 to move, thereby driving the sliding frame 9 to move in the slide groove 6, thereby driving the sliding frame 2 to move in the tool holder frame 1, so that the workpiece is processed by the tool. During the processing, in order to reduce the friction between the tool and the workpiece, reduce the cutting force, thereby allowing the use of a higher cutting speed and feed rate, and improve the processing efficiency, it is also necessary to spray coolant at the processing position. At this time, the spray component is started to spray the coolant at the processing position. The spraying can quickly absorb and take away the heat of the tool and the workpiece, maintain the low temperature state of the processing area, and can also wash away the debris, thereby ensuring the processing quality. During the spraying process, the spraying position can also be adjusted according to different types of tools and cutting positions to ensure the stability of the spraying.

[0075] The above, such as Figure 3As shown, the guide portion includes a guide rod 11 and a sliding sleeve 12. Two guide rods 11 are symmetrically installed on both sides of the feed area. Multiple sliding sleeves 12 are fixedly installed on both sides of each sliding frame 2. The sliding sleeves 12 are slidably connected to the guide rods 11.

[0076] Specifically, when the sliding frame 2 slides inside the tool holder frame 1, the sliding frame 2 drives the sliding sleeve 12 to move along the guide rod 11, thereby ensuring stability during the feeding process, reducing the possibility of jamming during the movement, and improving the processing quality.

[0077] like Figures 5 to 8 As shown, the spray assembly is installed inside the sliding frame 2, and is used for spraying coolant in the cutting area and adjusting the spraying angle. The spray assembly includes a water pump 13, a joint 14, a water inlet pipe 15 and an annular water tank 16. The water pump 13 is fixedly installed inside the sliding frame 2, and the joint 14 is fixedly installed at one end of the sliding frame 2 away from the supporting frame 3. The water inlet pipe 15 is connected between the input end of the water pump 13 and the joint 14. An annular water tank 16 is opened on the mounting ring 5, and also includes a drain pipe 17, an annular frame 18, a spray part and a two-way adjustment part. The drain pipe 17 is connected between the output end of the water pump 13 and the annular water tank 16. An annular frame 18 is rotatably and sealingly installed on the annular water tank 16. The spray part is installed on the annular frame 18 for spraying coolant. The two-way adjustment part is installed on the annular frame 18 for adjusting the spraying angle and adjusting the position of the annular frame 18.

[0078] Specifically, when spraying is required, the corresponding pipeline is connected to the joint 14, and the pipeline is connected to the tank body storing the coolant. At this time, the water pump 13 is started, and the water pump 13 sucks the coolant from the tank body into the water inlet pipe 15. As the water pump 13 runs, it is then transported to the annular water tank 16 through the drain pipe 17. The annular water tank 16 forms a relatively closed space through the setting of the annular frame 18. At this time, the spray part is started, and the spray part can spray the coolant evenly on the cutting area, thereby reducing the temperature of the tool and the workpiece. When changing the tool or processing different positions of the workpiece, the spray angle can be adjusted according to actual needs through the cooperation of the two-way adjustment part to ensure accurate coverage of the coolant, thereby further optimizing the processing effect.

[0079] The above, such as Figure 8 As shown, the spray part includes a bracket 19, a swing frame 20, a nozzle 21 and a connecting pipe 22. The bracket 19 is fixedly mounted on the annular frame 18, the swing frame 20 is rotatably mounted on the end of the bracket 19, the nozzle 21 is fixedly mounted on the swing frame 20, and the connecting pipe 22 is fixedly mounted on the swing frame 20. One end of the connecting pipe 22 is connected to the nozzle 21, and the other end of the connecting pipe 22 is connected to the annular water tank 16.

[0080] Specifically, when the coolant fills the annular water tank 16, the nozzle 21 is turned on. The coolant in the annular water tank 16 will enter the connecting pipe 22 under the action of water pressure, and then be evenly sprayed on the cutting area through the nozzle 21. When adjusting the spray angle, the position of the swing frame 20 is adjusted to ensure that the nozzle 21 is accurately pointed and the coolant is evenly covered.

[0081] The above, such as Figure 7 , Figure 8 As shown, the two-way adjustment part includes a driven gear 23, an intermediate gear 24, a rack 25 and an electric cylinder 26. The driven gear 23 is fixedly mounted on the end of the swing frame 20. The driven gear 23 is rotatably connected to the bracket 19. The intermediate gear 24 is rotatably mounted on the inner wall of the bracket 19. The intermediate gear 24 meshes with the driven gear 23. The rack 25 is slidably mounted on the inner wall of the bracket 19. The rack 25 meshes with the intermediate gear 24. The electric cylinder 26 is fixedly mounted inside the bracket 19. The output end of the electric cylinder 26 is fixedly connected to the rack 25. It also includes a gear ring 27, a housing 28, a second gear 29 and a second motor 30. The gear ring 27 is fixedly mounted on the annular frame 18. The housing 28 is fixedly mounted on the supporting frame 3. The housing 28 is rotatably matched with the annular frame 18. The second gear 29 is rotatably mounted inside the housing 28. The second gear 29 meshes with the gear ring 27. The second motor 30 is fixedly mounted at the bottom of the supporting frame 3. The output end of the second motor 30 is fixedly connected to the second gear 29.

[0082] Specifically, when adjusting the angular position of the spray, the electric cylinder 26 is started, and the electric cylinder 26 pushes the rack 25 to slide on the inner wall of the bracket 19, thereby driving the intermediate gear 24 to rotate through the rack 25, and the intermediate gear 24 can drive the driven gear 23 to rotate, thereby adjusting the angle of the swing frame 20, and then adjusting the angular position of the spray. At the same time, when adjusting the circumferential position of the spray, the second motor 30 is started, and the second motor 30 drives the second gear 29 to rotate. Through the engagement of the second gear 29 with the gear ring 27, the gear ring 27 can be driven to rotate, and the gear ring 27 can drive the annular frame 18 to rotate on the annular water tank 16. Through the rotation of the annular frame 18, the position of the bracket 19 can be adjusted, thereby adjusting the circumferential position of the spray, ensuring that the coolant covers a wider range and improving processing accuracy and efficiency.

[0083] The above, such as Figure 5 As shown, it also includes a driving component, which is installed inside the sliding frame 2, including a mounting cylinder 31, a knife rod 32 and a driving unit. The mounting cylinder 31 is fixedly installed inside the bearing 4, and the mounting cylinder 31 is rotatably matched with the mounting ring 5. The knife rod 32 is detachably installed inside the mounting cylinder 31, and the driving unit is installed inside the sliding frame 2 for driving the mounting cylinder 31 to rotate.

[0084] Specifically, when in use, first install the required tool on the tool rod 32, then insert the tool rod 32 into the mounting tube 31 and fix the relative position between the mounting tube 31 and the tool rod 32, and then the workpiece can be processed. In order to adapt to different processing requirements and improve processing efficiency and quality, when necessary, start the driving part to drive the mounting tube 31 to rotate, thereby driving the tool to rotate through the tool rod 32, thereby adapting to different processing needs.

[0085] The above, such as Figure 5 As shown, the driving part includes a third motor 33, a first bevel gear 34 and a second bevel gear 35. The third motor 33 is fixedly mounted inside the sliding frame 2, the first bevel gear 34 is fixedly mounted on the mounting cylinder 31, and the second bevel gear 35 is fixedly mounted at the output end of the third motor 33. The second bevel gear 35 is meshed with the first bevel gear 34.

[0086] Specifically, when driving the installation tube 31 to rotate, the third motor 33 is started, and the third motor 33 drives the second bevel gear 35 to rotate. Through the meshing of the first bevel gear 34 and the second bevel gear 35 , the first bevel gear 34 drives the installation tube 31 to rotate.

[0087] The working principle or usage process of this application is:

[0088] When using a power tool holder, first install the required tool on the tool rod 32, then insert the tool rod 32 into the mounting cylinder 31 and fix the relative position between the mounting cylinder 31 and the tool rod 32, and then push the tool holder frame 1 to move on the lathe until the tool holder frame 1 is moved to the processing position, and then start processing the workpiece with the tool. In order to adapt to different processing requirements and improve processing efficiency and quality, when necessary, start the third motor 33, and the third motor 33 drives the second bevel gear 35 to rotate. Through the engagement of the first bevel gear 34 and the second bevel gear 35, the mounting cylinder 31 is driven to rotate through the first bevel gear 34, which can drive the mounting cylinder 31 to rotate, thereby driving the tool to rotate through the tool rod 32, thereby adapting to different processing needs.

[0089] During the processing, in order to increase the processing stroke, the first motor 7 is started, the first motor 7 drives the screw 8 to rotate, the screw 8 drives the feed nut 10 to move, thereby driving the sliding frame 9 to move in the slide groove 6, thereby driving the sliding frame 2 to move in the tool holder frame 1, so that the workpiece is processed by the tool. During this process, the sliding frame 2 drives the sliding sleeve 12 to move along the guide rod 11, thereby ensuring stability during the feeding process, reducing the possibility of jamming during the movement, and improving the processing quality.

[0090] In order to reduce the friction between the tool and the workpiece and reduce the cutting force during the machining process, thereby allowing the use of higher cutting speeds and feed rates and improving machining efficiency, it is also necessary to spray coolant at the machining position. In the process of spraying coolant, the corresponding pipeline is connected to the joint 14, and the pipeline is connected to the tank body storing the coolant. At this time, the water pump 13 is started, and the water pump 13 sucks the coolant from the tank body into the water inlet pipe 15. As the water pump 13 runs, it is then transported to the annular water tank 16 through the drain pipe 17. The annular water tank 16 forms a relatively closed space through the setting of the annular frame 18. When the coolant fills the annular water tank 16, the nozzle 21 is turned on. The coolant in the annular water tank 16 will enter the connecting pipe 22 under the action of water pressure, and then be evenly sprayed on the cutting area through the nozzle 21.

[0091] In order to ensure that the nozzle 21 is accurately pointed and the coolant is evenly covered, the position of the spray needs to be adjusted. When adjusting the angle position of the spray, the electric cylinder 26 is started, and the electric cylinder 26 pushes the rack 25 to slide on the inner wall of the bracket 19, thereby driving the intermediate gear 24 to rotate through the rack 25, and the intermediate gear 24 can drive the driven gear 23 to rotate, thereby adjusting the angle of the swing frame 20, and then adjusting the angle position of the spray. At the same time, when adjusting the circumferential position of the spray, the second motor 30 is started, and the second motor 30 drives the second gear 29 to rotate. Through the engagement of the second gear 29 and the gear ring 27, the gear ring 27 can be driven to rotate, and the gear ring 27 can drive the annular frame 18 to rotate on the annular water tank 16. Through the rotation of the annular frame 18, the position of the bracket 19 can be adjusted, so as to adjust the position of the spray according to different types of tools and cutting positions, thereby adjusting the position of the spray, ensuring that the coolant covers a wider range, further optimizing the processing effect, and ensuring the stability of the processing.

[0092] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
