Abstract
Description
Technical Field
[0001] This utility model relates to the field of machining technology, and in particular to a radial drilling machine equipped with a coolant spraying mechanism. Background Technology
[0002] Machining technology is the foundation and core area of modern manufacturing. Through processes such as cutting, milling, and grinding, it processes metallic or non-metallic materials to meet the precision manufacturing needs of complex parts. It is widely used in industries such as aerospace, automotive manufacturing, shipbuilding, and electronic equipment. This technology is characterized by high precision, high efficiency, and versatility, covering multiple stages from raw materials to finished product manufacturing, and is an indispensable part of industrial production. Radial drilling machines, as important equipment in machining, have advantages such as high flexibility, wide processing range, and high adaptability. They are particularly suitable for drilling, reaming, and countersinking of large, complex, or irregular workpieces. Their radial arms can be flexibly adjusted in position and angle, providing multi-functional support for workpieces of different sizes and shapes. At the same time, relying on a robust spindle design and a precise speed control system, it ensures high-quality and high-efficiency machining.
[0003] A radial drilling machine is a specialized machine tool used for drilling, reaming, and countersinking operations, widely used in the machinery manufacturing and processing industries. Its structure mainly includes a base, column, radial arm, spindle box, and worktable. The base provides stable support for the machine, while the column supports the radial arm and allows it to slide up and down and rotate around the column, thus adjusting the machining position. The radial arm is its core component, adapting to the machining requirements of different workpieces through rotation and movement. The spindle box houses the spindle and transmission device; the spindle is used to fix and drive the cutting tool to achieve the drilling action. The worktable supports and fixes the workpiece. Radial drilling machines are characterized by a large machining range, high flexibility, and ease of operation, making them particularly suitable for machining large or complex-shaped workpieces. Their structural design allows the machine to adapt to various machining scenarios while maintaining high precision and efficiency, making it an indispensable tool in machining.
[0004] The coolant spraying mechanism on a radial drilling machine is an important auxiliary device used to improve machining conditions and protect cutting tools and workpieces. It mainly consists of a coolant pump, delivery pipelines, nozzles, and a coolant tank. Its working principle is that the coolant pump draws coolant from the tank, delivers it through the pipelines to the nozzles, and then precisely sprays it onto the cutting area. The main functions of coolant in a radial drilling machine are cooling, lubrication, and cleaning. It removes the high temperatures generated during cutting, preventing overheating damage to the cutting tools and workpiece; reduces friction and cutting forces, improving machining accuracy and surface quality; and removes chips, keeping the machining area clean and preventing secondary damage.
[0005] However, existing cooling spray mechanisms on radial drilling machines still have some shortcomings and defects: First, coolant and debris tend to stagnate in the worktable channels, leading to accumulation, which not only affects the cooling effect but also increases the burden of manual cleaning. Second, traditional coolant recovery systems mostly use a single filtration method, which is difficult to completely remove fine iron filings and impurities, resulting in insufficient coolant cleanliness, thus affecting machining quality and the long-term stability of the equipment. In addition, the lack of effective iron filings separation measures means that tiny iron filings remain in the coolant, which may damage the cutting tools or machined surfaces; debris accumulation in the recovery system can also easily clog pipes and the cooling system, increasing equipment failure rates and reducing machining efficiency.
[0006] To address the above problems, a radial drilling machine with a coolant spraying mechanism is proposed. Utility Model Content
[0007] To overcome the above shortcomings, this utility model provides a radial drilling machine with a coolant spraying mechanism, which aims to solve the problems of coolant and debris accumulating inside the platform tank and the difficulty in recycling coolant.
[0008] To achieve the above objectives, the present invention adopts the following technical solution: a radial drilling machine with a coolant spraying mechanism, comprising a base and a recovery pump, wherein a column is fixedly connected to one side of the top of the base, a rocker arm is rotatably connected to the middle of the column, a spindle box is provided on the rocker arm, a spindle is installed at the bottom of the spindle box, a worktable is mounted on the top of the base, and auxiliary cleaning and recovery components and a cooling component are respectively provided on the front and rear sides of the column, wherein the cooling component is connected to a secondary cleaning mechanism through a pipe and a recovery pump;
[0009] The auxiliary cleaning and recycling component includes a fan, which is fixedly connected to the top corner of the base. The air outlet of the fan is fixedly connected to a main air duct, and multiple independent blowers are provided at the top and bottom of the main air duct.
[0010] As a further description of the above technical solution:
[0011] The workbench has multiple slots that are tilted downwards at a 15° angle, and the output end of the independent blower head faces the inside of the slots.
[0012] As a further description of the above technical solution:
[0013] The workbench is inclined with a guide plate at one end away from the column. The guide plate has arc-shaped grooves inside that correspond to the number of slots on the workbench. A recycling box is provided at the bottom of the guide plate, and a coarse filter plate is installed inside the recycling box.
[0014] As a further description of the above technical solution:
[0015] The cooling assembly includes a coolant tank, a coolant pump is mounted on the top of the coolant tank, and a delivery pipe is mounted on the output end of the coolant pump. The end of the delivery pipe away from the coolant pump is located directly above the workbench.
[0016] As a further description of the above technical solution:
[0017] The secondary cleaning mechanism includes two fixed frames, with a fixing component on the top of each frame and a cleaning component inside the frame.
[0018] As a further description of the above technical solution:
[0019] The fixing component includes limiting posts, which are fixedly connected to the top of the fixing frame, and limiting plates are sleeved on the outer sides of the two limiting posts.
[0020] As a further description of the above technical solution:
[0021] The cleaning assembly includes a connecting tube, with a fine filter screen installed on the inner side of the connecting tube and a powerful magnetic ring sleeved on the outer side of the connecting tube.
[0022] As a further description of the above technical solution:
[0023] The recycling bin is equipped with a flow guide pipe inside. One end of the connecting pipe is connected to the flow guide pipe, and the other end is connected to the input end of the recycling pump.
[0024] This utility model has the following beneficial effects:
[0025] 1. In this invention, the airflow generated by the fan effectively pushes away the coolant and debris trapped in the workbench channel, preventing accumulation. Furthermore, the workbench channel is tilted at a certain angle, facilitating the coolant carrying debris through the guide plate into the recovery tank, reducing the burden of manual cleaning. This achieves automated cleaning of the processing area, maintaining a clean working environment; improves the recovery efficiency of coolant and debris, aiding in secondary filtration and recycling; and reduces the risk of debris clogging the cooling system, thereby lowering equipment failure rates and improving overall processing efficiency and equipment stability.
[0026] 2. In this invention, the coolant containing debris first undergoes initial filtration through a coarse filter plate in the recovery tank, intercepting larger particles of impurities. Under the action of the recovery pump, the coolant is introduced into the guide pipe and then into the connecting pipe, where it undergoes secondary filtration through a fine filter screen to remove finer impurities. Simultaneously, a powerful magnetic ring is fitted onto the outside of the connecting pipe to further adsorb and separate any remaining fine iron filings in the coolant. Through the synergistic effect of the multiple cleaning devices—coarse filtration, fine filter screen, and magnetic ring—the coolant is effectively purified, ensuring its cleanliness and providing efficient and stable cooling support for subsequent processing.

[0034] 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.
[0035] Reference Figure 1 - Figure 3 This utility model provides an embodiment of a radial drilling machine with a coolant spraying mechanism, comprising a base 1 and a recovery pump 12. A column 2 is fixedly connected to one side of the top of the base 1, and a radial arm 4 is rotatably connected to the middle of the column 2. A spindle box 3 is mounted on the radial arm 4, and a spindle 5 is mounted at the bottom of the spindle box 3. The operator can operate the equipment to flexibly rotate the spindle 5, thereby processing various parts of the workpiece. A worktable 8 is mounted on the top of the base 1 for supporting and fixing the workpiece. The cooling assembly 6 includes a coolant tank 601, and a coolant pump 602 is mounted on the top of the coolant tank 601. The output end of the coolant pump 602 is connected to a delivery pipe 603. The other end of the delivery pipe 603 is located directly above the worktable 8, enabling precise spraying of coolant onto the cutting area to ensure sufficient cooling and lubrication of the workpiece and tool, while simultaneously flushing away chips and preventing secondary contamination. An auxiliary cleaning and recovery assembly 7 is provided on the front side of the column 2. The auxiliary cleaning and recovery assembly 7 includes a fan 701, which is fixedly connected to the top corner of the base 1. Its air outlet is connected to the main air duct 702. The top and bottom of the main air duct 702 are provided with multiple independent blowers 703. The output ends of these independent blowers 703 are aligned with multiple slots 14 inside the workbench 8. The slots 14 are designed to be inclined downward at 15°, which is conducive to the flow of coolant and debris to the end of the workbench 8 away from the column 2 under the push of the wind. A guide plate 9 is inclined at this end. The guide plate 9 has arc-shaped grooves inside that correspond to the number of slots 14, which further guide the coolant and debris into the recovery box 10 at the bottom. A coarse filter plate 11 is installed inside the recovery box 10 for preliminary filtration of the recovered coolant and debris.
[0036] Reference Figure 2 , Figure 4 and Figure 5The secondary cleaning mechanism 13 includes two fixed frames 1302, which support and fix the cleaning components to ensure stable operation. Each of the two fixed frames 1302 has a fixing component on its top. Each fixing component includes a limiting post 1305, which is fixedly connected to the top of the fixed frame 1302 and has a limiting plate 1303 fitted on its outer side. The limiting plate 1303 is designed to limit the range of motion of the cleaning components, ensuring efficient and accurate positioning during the cleaning process. The cleaning components are installed inside the fixed frames 1302 and include a connecting pipe 1304, a fine filter screen 1306, and a powerful magnetic ring 1307. The connecting pipe 1304 is a key channel for conveying coolant. A fine filter screen 1306 is installed on its inner side to deeply filter tiny particulate impurities in the coolant. A powerful magnetic ring 1307 is fitted on the outer side of the connecting pipe 1304. This magnetic ring is designed to adsorb any fine iron filings that may remain in the coolant, achieving multiple purification steps and further improving the cleanliness of the coolant.
[0037] The coolant recovery path begins at the recovery tank 10. The recovery tank 10 is equipped with a guide pipe 1301 to guide the coolant flow to the secondary cleaning mechanism 13. One end of the guide pipe 1301 is connected to a connecting pipe 1304, ensuring that the recovered coolant reaches a high purification standard after passing through the cleaning assembly. The other end of the connecting pipe 1304 is connected to the input end of the recovery pump 12. The recovery pump 12 is responsible for transporting the purified coolant to the coolant tank 601 of the cooling assembly 6, realizing the recycling of the coolant. Through multiple cleaning processes including coarse filtration, fine filtration, and magnetic adsorption, large particulate impurities, fine debris, and iron filings in the coolant are thoroughly removed. This not only extends the service life of the coolant but also reduces the risk of cooling system failure, further improving the machining efficiency and environmental performance of the radial drilling machine.
[0038] Working Principle: First, the cooling assembly 6 uses a coolant pump 602 to deliver coolant from the coolant tank 601 to above the worktable 8, precisely spraying it onto the machining area to provide cooling and lubrication for the workpiece and cutting tools, while simultaneously flushing away chips. The coolant and chips then enter the inclined trough 14 and, propelled by the airflow generated by the fan 701 in the auxiliary cleaning and recovery assembly 7, flow through the guide plate 9 into the recovery tank 10. The coarse filter plate 11 in the recovery tank 10 performs preliminary filtration of the coolant, removing large particles of impurities, before it enters the secondary cleaning mechanism 13 through the guide pipe 1301. The secondary cleaning mechanism 13 further removes fine impurities through a fine filter screen 1306, while a powerful magnetic ring 1307 adsorbs tiny iron filings in the coolant. The coolant, after multiple purification processes, is returned to the coolant tank 601 by the recovery pump 12 for recycling. The entire system integrates cooling, cleaning, and recovery functions, ensuring high cleanliness of the coolant, effectively improving processing efficiency, and reducing the risk of equipment failure.
[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
