Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of oil inlet pipeline structure design, specifically to an oil inlet structure for a deep hole drilling and boring machine and the deep hole drilling and boring machine itself. Background Technology
[0002] Deep hole drilling and boring machines are mainly used for deep hole machining, including drilling, reaming, and boring operations. Large deep hole drilling and boring machines require a large flow rate of cutting fluid to cool the cutting tools and workpiece, and simultaneously flush out the chips generated during cutting. Existing deep hole drilling and boring machines typically use a large-diameter oil supply pipe connecting the oil pump and the oil feeder to meet the high-flow-rate oil delivery requirements. The oil pump is usually fixedly mounted on the machine bed, and the oil feeder is a follower component that moves with the spindle and feed system. However, when machining deep workpieces, the large-diameter oil supply hose exhibits a large bending radius as it follows the oil feeder. The large-diameter hose has poor mobility, making position adjustment difficult and affecting its service life. Utility Model Content
[0003] In view of the problems existing in the prior art, the present invention provides an oil inlet structure for a deep hole drilling and boring machine and a deep hole drilling and boring machine, so as to improve the technical problems of poor oil pipe movement flexibility and difficulty in adjusting the position when the existing deep hole drilling and boring machine performs deep machining on the workpiece.
[0004] To solve the above-mentioned technical problems, this utility model provides an oil inlet structure for a deep hole drilling and boring machine and the deep hole drilling and boring machine itself. The oil inlet structure of the deep hole drilling and boring machine includes an oil distributor, an oil collector, and multiple oil delivery pipes. The oil distributor has a first oil inlet and multiple first oil outlets, the first oil inlet being connected to the oil supply pump of the deep hole drilling and boring machine. The oil collector has a second oil outlet and multiple second oil inlets, the second oil outlets being connected to the oil feeder of the deep hole drilling and boring machine. One end of each of the multiple oil delivery pipes is connected to the multiple first oil outlets, and the other end of each of the multiple oil delivery pipes is connected to the multiple second oil inlets.
[0005] In one embodiment of the oil inlet structure of this utility model, the oil inlet structure further includes a cable chain, and a plurality of oil supply pipes are disposed within the cable chain.

[0008] In one embodiment of the oil inlet structure of this utility model, the flow cross-sectional area of the second oil outlet is greater than or equal to the sum of the flow cross-sectional areas of multiple second oil inlets.
[0009] In one embodiment of the oil inlet structure of this utility model, the oil distributor includes an oil collecting pipe, a flange, and multiple branch pipes. One end of the oil collecting pipe is an open end, forming the first oil inlet, and the other end of the oil collecting pipe is a closed end. The flange is disposed at the open end of the oil collecting pipe. Multiple branch pipes are spaced apart on the oil collecting pipe; the first oil outlet is opened on the branch pipe.

[0027] To address the technical problems of poor oil pipe movement flexibility and difficulty in adjusting the position of the oil supply pipe during deep hole drilling and boring machines, this invention provides an oil inlet structure for a deep hole drilling and boring machine and the machine itself. This oil inlet structure allows for a smaller bending radius of the oil supply pipe, reduces the difficulty of adjusting the oil supply pipe's movement in accordance with the feed motion of the oil feeder, and improves the flexibility of oil pipe movement adjustment.
[0028] Please see Figures 1 to 6 This utility model provides an oil inlet structure for a deep hole drilling and boring machine and the deep hole drilling and boring machine itself. The oil inlet structure includes an oil distributor 100, an oil collector 200, and multiple oil delivery pipes 300. The oil distributor 100 adopts a one-inlet-multiple-outlet oil inlet configuration, having a first oil inlet 110 and multiple first oil outlets 120. The first oil inlet 110 is connected to the oil supply pump 700 of the deep hole drilling and boring machine; specifically, the first oil inlet 110 is connected to the oil outlet of the oil supply pump 700, receiving oil or coolant pumped out by the oil supply pump 700. The multiple first oil outlets 120 are the oil distribution ports of the oil distributor 100, and the inner diameter of each first oil outlet 120 is smaller than that of the first oil inlet 110. The oil collector 200 adopts a one-outlet-multiple-inlet oil outlet configuration. It has a second oil outlet 210 and multiple second oil inlets 220. The inner diameter of the second oil outlet 210 is larger than the inner diameter of a single second oil inlet 220. The second oil outlet 210 connects to the oil feeder 600 of the deep hole drilling and boring machine, delivering the oil or coolant collected in the oil collector 200 to the oil feeder 600. The oil feeder 600 then connects to the tool spindle to achieve cooling of the tool or workpiece within the hole and to remove chips. Multiple oil supply pipes 300 replace the original single large-diameter oil pipe structure of the deep hole drilling and boring machine. One end of each oil supply pipe 300 connects to multiple first oil outlets 120, and the other end connects to multiple second oil inlets 220. Specifically, each end of a single oil pipe 300 is connected to a first oil outlet 120 and a second oil inlet 220. The number of the first oil outlet 120, the second oil inlet 220, and the oil pipe 300 is the same, but the specific number is not limited. It can be determined by comprehensively considering the oil delivery volume required by the deep hole drilling and boring machine, the size of the original single oil pipe, and the inner diameter of the oil pipe 300 actually selected.
[0029] This oil inlet structure does not alter the original interface structure of the oil supply pump 700 and oil distributor 600 of the deep hole drilling and boring machine. The oil distributor 100 can be matched with a corresponding connection structure according to the structure of the oil outlet of the oil supply pump 700, and the oil collector 200 can be matched with a corresponding connection structure according to the structure of the oil inlet of the oil distributor 600. Therefore, the original deep hole drilling and boring machine structure requires minimal modification, facilitating the installation and connection of this oil inlet structure. Multiple smaller-diameter oil delivery pipes 300 replace the original large-diameter oil pipes of the deep hole drilling and boring machine. The smaller-diameter oil delivery pipes 300 allow for a smaller bending radius, reducing the difficulty of adjusting the oil delivery pipes 300 to follow the feed motion of the oil distributor 600, improving the flexibility of the oil delivery pipes 300's movement adjustment, and ensuring the service life of the oil delivery pipes 300.
[0030] Please see Figure 1 and Figure 3 In one embodiment of the oil inlet structure of this utility model, the oil inlet structure further includes a cable chain 400, and multiple oil delivery pipes 300 are disposed within the cable chain 400. One end of the cable chain 400 is a fixed end, and the other end is a movable end. The fixed end of the cable chain 400 is connected to the machine bed 500 of a deep hole drilling and boring machine. Specifically, the fixed end of the cable chain 400 is connected to the machine bed 500 of the deep hole drilling and boring machine located near the oil supply pump 700. The movable end of the cable chain 400 is connected to the oil feeder 600, that is, to the housing structure at the oil feeder 600, as long as it can move synchronously with the oil feeder 600. The size and type of the cable chain 400 are not limited and can be determined comprehensively according to the number of oil delivery pipes 300, as long as the internal cavity of the cable chain 400 can accommodate and converge multiple oil delivery pipes 300. The application of the cable chain 400, while meeting the flow supply requirements of the oil distributor 600 in this oil inlet structure, reduces the scattered layout of multiple oil delivery pipes 300, minimizes space occupation, and further enhances the following flexibility of the oil delivery pipes 300. It eliminates the need for manual adjustment of the oil delivery pipes 300's position, improving their mobility and ease of use. It should be noted that the cable chain 400 can be obtained through general commercial means.
[0031] Please see Figure 1 In one embodiment of the oil inlet structure of this utility model, a support plate 410 is also provided at the lower part of the cable chain 400. The support plate 410 is fixedly installed on the side of the machine tool bed 500. The support plate 410 has a groove structure and supports the part of the cable chain 400 that has not been bent or moved, thereby improving the running stability of the cable chain 400 during the position adjustment process.
[0032] In one embodiment of the oil inlet structure of this utility model, the sum of the flow cross-sectional areas of the plurality of first oil outlets 120 is greater than or equal to the flow cross-sectional area of the first oil inlet 110. Specifically, the inner diameter cross-sectional area of the first oil inlet 110 matches the oil outlet of the oil supply pump 700, that is, the inner diameter cross-sectional area of the first oil inlet 110 is consistent with the inner diameter cross-sectional area of the oil inlet of the original single oil pipe. Under the condition that the oil supply capacity of the oil supply pump 700 remains unchanged, in order to ensure sufficient oil supply to the deep hole drilling and boring machine, and to ensure the oil output of the oil distributor 100, that is, the sum of the inner diameter cross-sectional areas of the plurality of first oil outlets 120 is not less than the inner diameter cross-sectional area of the first oil inlet 110, so as to ensure that although multiple oil supply pipes 300 replace a single large oil pipe, the oil supply effect of the original single large oil pipe can still be met, thereby ensuring the oil demand of the deep hole drilling and boring machine.
[0033] Similarly, the flow cross-sectional area of the second oil outlet 210 is greater than or equal to the sum of the flow cross-sectional areas of the multiple second oil inlets 220. That is, the multiple second oil inlets 220 of the oil collector 200 collect the oil or coolant output from multiple oil supply pipes 300 and supply it to the oil inlet of the oil distributor 600. The inner diameter cross-sectional area of the second oil outlet 210 matches the oil inlet of the oil distributor 600, that is, the inner diameter cross-sectional area of the second oil outlet 210 is consistent with the inner diameter cross-sectional area of the oil outlet of the original single oil pipe. To ensure sufficient oil supply to the deep hole drilling and boring machine and to guarantee the oil output of the oil collector 200, the inner diameter cross-sectional area of the second oil outlet 210 is not less than the sum of the inner diameter cross-sectional areas of the multiple second oil inlets 220. This ensures that even though multiple oil pipes 300 replace a single large oil pipe, the oil supply capacity of the original single large oil pipe to the oil distributor 600 can still be met, thereby guaranteeing the oil supply to the deep hole drilling and boring machine.
[0034] Please see Figure 4In one embodiment of the oil inlet structure of this utility model, the oil distributor 100 can be a purchased product obtained through general commercial means or a self-made structure. Specifically, in this embodiment, the oil distributor 100 is a self-made structure, which includes an oil collecting pipe 130, a flange 140, and multiple diversion pipes 150. The oil collecting pipe 130 is a pipe structure, such as a steel pipe, with one end being an open end, which serves as the first oil inlet 110 of the oil distributor 100. The other end of the oil collecting pipe 130 is a closed end, and the pipe body of the oil collecting pipe 130 serves as a receiving cavity before diversion. The flange 140 is disposed at the open end of the oil collecting pipe 130, and the flange 140 is a connecting piece for connecting the oil distributor 100 to the oil supply pump 700. The oil distributor 100 and the oil supply pump 700 are connected through the flange. Multiple diverter pipes 150 are spaced apart on the body of the oil collecting pipe 130. The diverter pipe 150 is also a pipe structure. Both ends of the diverter pipe 150 are open structures. One end of the diverter pipe 150 extends into the receiving cavity of the oil collecting pipe 130, and the other end serves as the first oil outlet 120, that is, the diverter port of the oil distributor 100 is connected to the oil delivery pipe 300.
[0035] Please see Figure 4 and Figure 5 In one embodiment of the oil inlet structure of this utility model, the oil separator 100 and the oil collector 200 have the same structure. The oil separator 100 and the oil collector 200 adopt the same structure and can be designed as modular components, facilitating production, installation, and maintenance. Simultaneously, it ensures that the original oil supply effect is maintained after oil separation and collection by the oil inlet structure, ensuring the oil volume requirements of the deep hole drilling and boring machine.
[0036] In one embodiment of the oil inlet structure of this utility model, the oil delivery pipe 300 is made of steel wire braided rubber hose. The steel wire braided rubber hose has good pressure resistance, and its end has a built-in connector, making it easy to adapt to the connection structure of the diversion pipe 150 to form a stable threaded connection. This further reduces design complexity. It should be noted that the steel wire braided rubber hose can be obtained through common commercial means.
[0037] In one embodiment of the oil inlet structure of this utility model, the inner diameter of the oil delivery pipe 300 is D, where 19mm ≤ D ≤ 35mm. Specifically, the oil delivery pipe 300 can be a high-pressure braided hose with an inner diameter of 19mm, 22mm, 25mm, or 32mm. Compared to the original large-diameter oil pipes, this range of inner diameter allows for multiple pipes to replace a single one, while maintaining the number of oil delivery pipes 300 within a suitable range, better matching the use of the cable chain 400.
[0038] Please see Figure 6The second aspect of this utility model also provides a deep hole drilling and boring machine, which includes the oil inlet structure described in any of the above embodiments. It should be noted that the deep hole drilling and boring machine of this utility model also includes conventional components and layout structures of existing deep hole drilling and boring machines, such as the main machine tool structure (e.g., machine bed, guide rail system), oil supply pump, oil feeder, spindle box, feed system, guiding and support system, tool system, and control system, which will not be described in detail here.
[0039] In this utility model, the oil inlet structure of the deep hole drilling and boring machine does not alter the original interface structure of the oil pump and oil feeder. By matching a suitable oil distributor and oil collector, the original deep hole drilling and boring machine structure requires minimal modification, facilitating the installation and connection of the oil inlet structure. Simultaneously, multiple smaller-diameter oil pipes replace the original large-diameter oil pipes of the deep hole drilling and boring machine. The smaller diameter oil pipes achieve a smaller bending radius, reducing the difficulty of adjusting the oil pipes when they follow the feed movement of the oil feeder, improving the flexibility of oil pipe movement adjustment, and ensuring the service life of the oil pipes. This improves the technical problem of poor oil pipe movement flexibility and difficulty in adjusting the position when performing deep-hole machining on existing deep hole drilling and boring machines. Therefore, this utility model effectively overcomes some practical problems in the prior art, thus having high utilization value and practical significance.
[0040] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
