Description

Technical Field

[0001] This utility model relates to the field of machining technology, specifically to an automatic air-blowing tool holder device. Background Technology

[0002] An insulator is a device installed between conductors at different potentials or between a conductor and a grounding component, capable of withstanding voltage and mechanical stress. Insulators come in many types and shapes, and while their structures and appearances vary considerably, they all consist of two main parts: an insulating component and connecting hardware. Holes are machined into the ends of the hardware, the insulating component is installed within these holes, and then the hardware is pressed to clamp the insulating component, with sealant applied between the insulating component and the inner wall of the hole. Most connecting hardware needs to withstand significant tensile forces during operation, typically 30KN-36KN, while maintaining good electrical contact. Since connecting hardware is often used in outdoor environments, it is frequently hot-dip galvanized to improve corrosion resistance before the holes are machined. The galvanized layer is prone to acid-base reactions with cutting fluids, affecting the surface quality of the connecting hardware, and the iron filings generated during processing affect the tensile strength between the insulator and the connecting hardware. Therefore, cleaning agents are needed to remove the iron filings; however, the wastewater recovery cost after cleaning is high. The manual method of blowing with compressed air has the problems of high labor intensity and low production efficiency. Therefore, how to ensure that the processed connecting hardware meets the requirements has become a problem that needs to be solved. Utility Model Content

[0003] This utility model addresses the existing technical problems by providing an automatic air-blowing knife holder device.

[0004] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: An automatic air-blowing knife holder device includes a frame, a turntable mounted on the frame, and a driving device. The driving device is used to drive the turntable to rotate. It also includes a knife body assembly, a support base, and an air inlet base. The knife body assembly and the support base are mounted on the turntable. Multiple knife body assemblies are provided, each including a knife clamp and a knife head mounted on the knife clamp. The knife head has a communicating air inlet channel and an air outlet, with the air outlet located on the knife head. At the end of the blade, the air inlet seat is rotatably connected to the support seat. The air inlet seat is provided with a second air inlet channel and an air outlet channel. The second air inlet channel is connected to an air source. The support seat is provided with a second air outlet. There are multiple second air outlets. The multiple second air outlets are arranged around the circumference of the support seat. Each second air outlet corresponds to a blade assembly. The second air outlet is connected to the first air inlet channel of the blade head through a distribution pipe. The gas in the air outlet channel is blown into the blade head at the machining station through the second air outlet and the distribution pipe.

[0005] The beneficial effects of this invention are as follows: By setting an air inlet channel and an air outlet on the cutting head, gas is introduced into the cutting head at the machining station. This achieves air cooling of the cutting head, reducing its temperature and extending its service life. It also enables rapid and continuous blowing away of metal chips during machining, ensuring the finished workpiece meets cleanliness requirements. This eliminates the need for a separate workpiece cleaning step, improving overall machining efficiency and reducing costs. Since no cutting fluid is used in the machining process, the problem of cutting fluid reacting with the workpiece coating and affecting surface quality is solved. Furthermore, no cleaning agent is required, further saving on machining costs and wastewater recovery costs.

[0006] Based on the above technical solution, the present invention can further improve the above technical solution as follows:

[0007] Furthermore, the support base is provided with a receiving groove, and the air intake seat is installed in the receiving groove by bearing.

[0008] The beneficial effect of adopting the above-mentioned further technical solution is that it ensures that the support seat can rotate flexibly relative to the air inlet seat, so that the gas in the air inlet seat can enter the cutting head at the machining position normally.

[0009] Furthermore, the turntable includes an upper pressure plate and a lower pressure plate, the tool holder is detachably installed between the upper pressure plate and the lower pressure plate, and a plurality of the tool body assemblies are arranged circumferentially along the turntable.

[0010] The beneficial effects of adopting the above-mentioned further technical solution are that the tool holder is positioned by the upper and lower pressure plates, which facilitates the adjustment of the tool holder position and ensures the convenience of tool holder assembly and disassembly. Multiple tool body components are arranged circumferentially, and when the turntable rotates, different tool body components can be rotated to the processing station to process the workpiece, meet the processing requirements of different processes of the workpiece, and improve the workpiece processing efficiency.

[0011] Furthermore, the turntable is rectangular, and there are four blade holders and four air outlets, with different types of blades mounted on the four blade holders.

[0012] The beneficial effects of adopting the above-mentioned further technical solution are that it facilitates the control of the rotation angle of the turntable, ensures that the tool body assembly rotates accurately to the machining station, ensures normal workpiece machining, and meets the machining requirements of different processes by installing different types of tool heads, thereby improving machining efficiency.

[0013] Furthermore, the air intake seat is generally inverted T-shaped, the second air intake channel is arranged along the axial direction of the air intake seat, and the air outlet channel is arranged along the radial direction of the air intake seat.

[0014] The advantages of adopting the above-mentioned further technical solutions are that the overall structure is simple, the installation is convenient, and the processing difficulty is reduced.

[0015] Furthermore, the air intake seat is connected to the air source through the main air pipe. The main air pipe includes a metal pipe one, a flexible hose and a metal pipe two. One end of the flexible hose is connected to the metal pipe one and the other end is connected to the metal pipe two. The metal pipe one is connected to the air intake channel two. The metal pipe two is inserted into the support block. The support block is installed on the frame through the support rod.

[0016] The beneficial effects of adopting the above-mentioned further technical solution are that by setting metal pipes at both ends of the hose, interference between the main air pipe and other parts is avoided, ensuring the normal rotation of the turntable. By setting the hose, a margin for movement is provided, ensuring flexibility and convenience in use.

[0017] Furthermore, the metal tube one includes an L-shaped, interconnected long tube and a short tube, the short tube being installed on the air intake channel two, and the length of the long tube being greater than the rotation radius of the turntable.

[0018] The advantages of adopting the above-mentioned further technical solution are that the structure is simple and the installation is convenient. At the same time, it further avoids interference between the main air pipe and the turntable, the air distribution pipe and the tool body assembly, and ensures that the turntable rotates different tool body assemblies to the processing station to ensure normal workpiece processing.

[0019] Furthermore, it also includes a clamp located on one side of the turntable, the clamp being used to clamp the workpiece.

[0020] The beneficial effect of adopting the above-mentioned further technical solution is that it meets the clamping requirements of the workpiece to be processed and improves the convenience of processing.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0029] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0030] like Figures 1 to 4As shown, this utility model discloses an automatic air-blowing tool holder device, including a frame 9, a turntable 1 mounted on the frame 9, and a driving device. The driving device is used to drive the turntable 1 to rotate. A support plate 18 is mounted on the frame 9, and a clamp 10 for clamping a workpiece is mounted on the support plate 18. In this embodiment, the workpiece is a connecting fitting. The clamp 10 is located on one side of the turntable 1, and the clamp 10 can drive the workpiece to rotate, which facilitates the processing of the workpiece. It also includes a tool body assembly, a support base 3, and an air inlet 4. The tool body assembly and the support base 3 are mounted on the turntable 1. There are multiple tool body assemblies. Each tool body assembly includes a tool holder 2 and a tool head 2-1 mounted on the tool holder 2. The tool head 2-1 has a communicating air inlet channel and an air outlet 2-2. The air inlet channel runs along the tool head. The head 2-1 extends along its length. The air outlet 2-2 is located at the end of the cutter head 2-1. The air inlet seat 4 is rotatably connected to the support seat 3. The air inlet seat 4 is provided with a connecting air inlet channel 4-1 and an air outlet channel 4-2. The air inlet channel 4-1 is connected to an air source through a main air pipe 5. The air source can be a gas compressor. The support seat 3 is provided with an air outlet 3-1. There are multiple air outlets 3-1. The multiple air outlets 3-1 are arranged around the support seat 3. Each air outlet 3-1 corresponds to a cutter body assembly. The air outlet 3-1 is connected to the air inlet channel 1 of the cutter head 2-1 through a distribution pipe 6. The gas in the air outlet channel 4-2 is blown into the cutter head 2-1 at the processing station through the air outlet 3-1 and the distribution pipe 6. When the cutting head 2-1 is in the machining station, the air outlet 3-1 corresponding to the cutting head 2-1 is connected to the air outlet channel 4-2, so that when the cutting head 2-1 is machining the workpiece, the cutting head 2-1 is cooled by gas and the iron filings are continuously blown away to ensure the cleanliness of the workpiece.

[0031] The automatic air-blowing tool holder device also includes a drive motor 8, a longitudinal slider 12, a transverse slider 13, and a drive motor 15. The turntable 1 is mounted on the longitudinal slider 12, which is slidably mounted on the transverse slider 13. The output end of the drive motor 8 is connected to the longitudinal slider 12. The transverse slider 13 is slidably mounted on a slide rail 14 on the frame 9. The output end of the drive motor 15 is connected to the transverse slider 13. By controlling the transverse and longitudinal positions of the turntable 1 with the drive motors 8 and 15, the transverse and longitudinal positions of the tool head assembly are adjusted, enabling the tool body assembly on the turntable 1 to process workpieces normally. Specifically, the second drive motor 15 is mounted on the support plate 18. The output end of the second drive motor 15 passes through the support plate 18 and is connected to the screw 16. A guard plate 17 is installed on the horizontal slider 13. The guard plate 17 has an internal thread corresponding to the screw 16. When the second drive motor 15 is working, it drives the screw 16 to rotate, thereby driving the horizontal slider 13 to move along the slide rail 14, thereby adjusting the distance between the tool body assembly and the workpiece to ensure normal workpiece processing.

[0032] Furthermore, the support base 3 is provided with a receiving groove, and the air inlet seat 4 is installed in the receiving groove. A bearing 11 is provided between the air inlet seat 4 and the support base 3. This ensures that the support base 3 can rotate flexibly relative to the air inlet seat 4, so that the gas in the air inlet seat 4 can normally enter the cutting head 2-1 at the machining station.

[0033] The turntable 1 includes an upper pressure plate and a lower pressure plate. The blade holder 2 is detachably installed between the upper pressure plate and the lower pressure plate. Multiple blade body assemblies are arranged circumferentially along the turntable 1. Specifically, a receiving space is formed between the upper pressure plate and the lower pressure plate. The fixing seat of the blade holder 2 is installed in the receiving space, and then the upper pressure plate and the lower pressure plate are connected by bolts to ensure the firmness of the blade holder 2 installation.

[0034] Furthermore, the upper and lower pressure plates are provided with multiple through holes along the length direction for bolts to pass through, which facilitates the adjustment of the position of the tool holder 2, improves the convenience and flexibility of use, and increases processing efficiency.

[0035] The turntable 1 is rectangular. Four tool holders 2 and four air outlets 3-1 are provided. Each tool holder 2 corresponds one-to-one with an air outlet 3-1, and the four tool holders 2 are equipped with different types of cutting heads 2-1. This facilitates control of the turntable 1's rotation angle. The turntable 1 rotates 90° each time, ensuring the tool assembly accurately rotates to the machining station and guaranteeing normal workpiece processing. By installing different types of cutting heads 2-1, the processing requirements of different procedures can be met, eliminating the need for multiple clamping of the cutting heads 2-1 and improving processing efficiency.

[0036] The air inlet seat 4 is generally inverted T-shaped. The second air inlet channel 4-1 is arranged along the axial direction of the air inlet seat 4, and the air outlet channel 4-2 is arranged radially along the air inlet seat 4. There is only one air outlet channel 4-2. When a certain tool body assembly on the support seat 3 is located at the machining station, the air outlet channel 4-2 is connected to the air outlet 2-2 of the tool head 2-1 of that tool body assembly. This allows for the simultaneous blowing away of iron filings while machining the workpiece, ensuring gas pressure, and preventing the scattering of waste chips at the machining site caused by air blowing from other tool heads 2-1, thus ensuring the cleanliness of the machining site.

[0037] The main air pipe 5 includes a metal pipe 5-1, a flexible hose 5-2, and a metal pipe 5-3. One end of the flexible hose 5-2 is connected to the metal pipe 5-1, and the other end is connected to the metal pipe 5-3. The flexible hose 5-2 is a plastic or rubber hose. The metal pipe 5-1 is connected to the air intake channel 4-1. The metal pipe 5-1 and the air intake channel 4-1 can be sealed with a sealing tape to reduce gas leakage. The metal pipe 5-3 is inserted into the support block 7, and the support block 7 is mounted on the frame 9 via a support rod. By setting the metal pipe 5-1 and the metal pipe 5-3 at both ends of the flexible hose 5-2, interference between the main air pipe 5 and other parts is avoided, ensuring the normal rotation of the turntable 1. By setting the flexible hose 5-2, the main air pipe 5 has a certain margin to meet the usage requirements when the turntable 1 moves on the frame 9, improving the flexibility of use.

[0038] Furthermore, the metal tube 5-1 includes an L-shaped, interconnected long tube and a short tube. The short tube is connected to the air inlet channel 4-1, and the length of the long tube is greater than the rotation radius of the turntable 1. This prevents the flexible hose 5-2 from interfering with the turntable 1, the air distribution pipe 6, and the tool assembly, ensuring that the turntable 1 can rotate different tool assemblies to the processing position and guarantee normal workpiece processing.

[0039] Furthermore, by adjusting the height of the support block 7 on the support rod, the installation height of the metal tube 5-3 is adjusted, thereby adjusting the height of the hose 5-2, further reducing the possibility of interference between the hose 5-2 and other parts, and ensuring the normal rotation of the turntable 1.

[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
