Detailed implementation manners
[0017] The following description provides many different embodiments or examples for implementing different features of the present utility model. The elements and arrangements described in the following specific examples are only used to concisely express the present utility model, and they are only examples and not intended to limit the present utility model.
[0018] Some embodiments of the present application provide a lubricating oil recovery device, refer to Figures 1 to 3As shown in the figure, it includes an oil receiving assembly, an oil storage tank 200, and a second hose 300. The oil receiving assembly and the oil storage tank 200 are arranged in sequence along the first direction. When the recycling device is installed on the corresponding machine tool, the first direction should be parallel to the direction of gravity, and the oil storage tank 200 needs to be arranged below the oil receiving assembly to facilitate the lubricating oil to drip into the oil receiving assembly under the action of gravity and flow into the oil storage tank 200 for storage.
[0019] The oil receiving assembly is mainly used to receive the lubricating oil dripping from the machine tool. The oil receiving assembly includes a first hose 120 and at least two oil receiving boxes 110. The oil receiving box 110 is used for detachable connection with the machine tool. Generally, the oil receiving box 110 is directly fixed to the machine tool through connecting parts such as bolts and screws. The oil receiving box 110 is generally placed below the parts that need to be lubricated on the machine tool. In actual use, the number and distribution position of the oil receiving boxes 110 are determined according to the actual positions of the parts that need to be lubricated on the machine tool. In some automated truss vertical shafts, the oil receiving box 110 is generally placed at the bottom of the rack 820, the main guide rail and the sub-guide rail to collect the lubricating oil dripping from the rack 820 and the guide rail 810.
[0020] The first hose 120 is used to connect any two oil receiving boxes 110 so that all the oil receiving boxes 110 of the oil receiving assembly can communicate with each other. The first hose 120 plays a role of connection, connecting all the oil receiving boxes 110 together, so that the lubricating oil in all the oil receiving boxes 110 can flow to each other, balance the amount of lubricating oil in different oil receiving boxes 110, and make the lubricating oil in all the oil receiving boxes 110 maintain at the same horizontal height position, avoiding the situation that the lubricating oil in some oil receiving boxes 110 overflows due to excessive amount. In actual application, the number of the first hoses 120 can be confirmed according to the different positions and numbers of the oil receiving boxes 110, as long as all the oil receiving boxes 110 are finally connected. The first hose 120 is of a hose structure with low stiffness and can be bent under the action of external force to adapt to the installation positions of different oil receiving boxes 110. The first hose 120 can improve the installation flexibility of the entire recycling device.
[0021] The oil storage tank 200 has an oil storage chamber and an exhaust hole. The exhaust hole communicates the oil storage chamber with the external environment where the oil storage tank 200 is located. The second hose 300 communicates the oil storage tank 200 with any one of the oil receiving boxes 110. The oil storage chamber is mainly used to store the lubricating oil transported from the second hose 300. The external environment where the oil storage tank 200 is located is the atmospheric environment. The exhaust hole communicates the oil storage chamber with the atmospheric environment so that the lubricating oil transported by the second hose 300 can smoothly enter the oil storage chamber.
[0022] The oil storage tank 200 and the oil receiving assembly are arranged along the first direction. The oil storage tank 200 is located below the oil receiving assembly. After the lubricating oil drips into the oil receiving box 110 under the action of gravity, all the oil receiving boxes 110 are interconnected, and the lubricating oil flows within the range of the oil receiving box 110 of the oil receiving assembly and the first hose 120. One of the oil receiving boxes 110 of the oil receiving assembly is connected to the second hose 300. Under the action of gravity, the lubricating oil in the oil receiving assembly can flow into the oil storage tank 200 for storage under the reuse of gravity.
[0023] After the lubricating oil flows into the oil receiving box 110, it can be interconnected between multiple oil receiving boxes 110, avoiding the situation of overflow of lubricating oil in a single oil receiving box 110. At the same time, the space formed by the interconnection of multiple oil receiving boxes 110 for the lubricating oil to flow is connected to the oil storage tank 200 through the second hose 300, and the lubricating oil can flow into the oil storage tank 200 in time under the action of gravity, further avoiding the situation of excessive lubricating oil in the oil receiving box 110.
[0024] In some embodiments of the present application, the oil receiving box 110 has a first cavity 111 and a second cavity 112. Both the first cavity 111 and the second cavity 112 are used to accommodate the lubricating oil. Refer to Figure 6 As shown, the second cavity 112 is arranged relatively closer to the oil storage tank 200 than the first cavity 111, that is, the first cavity 111 is located above the second cavity 112. The first cavity 111 also has an oil receiving port for the external lubricating oil to enter. A communication hole 113 communicating with the second cavity 112 is provided on the bottom wall of the first cavity 111. Both the first hose 120 and the second hose 300 are connected to the second cavity 112, facilitating the lubricating oil to enter the hose.
[0025] After the lubricating oil on the machine tool drips, it passes through the oil receiving port of the first cavity 111 and drips into the first cavity 111, and then enters the second cavity 112 through the communication hole 113 under the action of gravity and flows into the first hose 120 and the second hose 300 in the second cavity 112. The lubricating oil dripping into the first cavity 111 can enter the second cavity 112 through the communication hole 113 in time. The presence of the second cavity 112 can reduce the amount of lubricating oil on the bottom wall of the first cavity 111. When the lubricating oil on the machine tool drips into the first cavity 111, the lubricating oil can directly contact the bottom wall of the first cavity 111. Since the amount of lubricating oil on the bottom wall of the first cavity 111 is small, the sputtering range after the lubricating oil drips is small, which can avoid the lubricating oil sputtering outside the oil receiving box 110, polluting the environment and products. Moreover, the size of the oil receiving box 110 can be correspondingly reduced, improving the flexibility of the entire recovery device.
[0026] In some preferred embodiments of the present application, the communication hole 113 is arranged close to the circumferential side wall of the first cavity 111. Refer to Figures 4 to 6As shown in the figure. The communication hole 113 is arranged as far as possible from the center of the bottom wall of the first cavity 111 and closer to the connection position between the bottom wall and the circumferential side wall of the first cavity 111. In such a layout, the integrity of the bottom wall of the first cavity 111 can be maintained as much as possible, avoiding the situation where external lubricating oil directly drips onto the edge of the communication hole 113, resulting in an enlarged sputtering range of the lubricating oil.
[0027] Further preferably, both axial ends of the second cavity 112 are open ends, and pipeline interfaces 400 are installed at both axial ends of the second cavity 112. Refer to Figure 6 As shown in the figure. The pipeline interface 400 is connected to the first hose 120, or the pipeline interface 400 is connected to the second hose 300, or a plug 700 is connected to the pipeline interface 400.
[0028] The pipeline interface 400 is pre-assembled onto the oil receiving box 110, and then the first hose 120 is directly connected to the pipeline interface 400 as needed, so that multiple oil receiving boxes 110 are interconnected; or the second hose 300 is connected to the pipeline interface 400 to connect the oil receiving box 110 to the storage tank 200. Or if only one pipeline interface 400 of the oil receiving box 110 is needed to be connected to the first hose 120 and the other pipeline interface 400 is useless, the plug 700 can be connected to this pipeline interface 400 to prevent accidental outflow of lubricating oil.
[0029] In some embodiments, connectors can be provided at the ends of the first hose 120, the second hose 300, and the plug 700. These connectors can be directly docked with the pipeline interface 400, thereby quickly and conveniently completing the connection between the hose and the pipeline interface 400, or the connection between the plug 700 and the pipeline interface 400.
[0030] The communication hole 113 between the first cavity 111 and the second cavity 112 is generally arranged at the circumferential side wall of the second cavity 112 and located between the two pipeline interfaces 400. Refer to Figure 6 As shown in the figure. Pipeline interfaces 400 are provided at both axial ends of the second cavity 112. The communication hole 113 is located at the circumferential side wall of the second cavity 112, and the communication hole 113 is located between the two pipeline interfaces 400. The mutual influence between the communication hole 113 and the pipeline interface 400 is reduced. The communication hole 113 does not affect the installation of the pipeline interface 400, and the pipeline interface 400 does not affect the communication between the communication hole 113 and the second cavity 112.
[0031] In some preferred embodiments of the present application, the two pipe interfaces 400 connected to the second cavity 112 are coaxially arranged, and the axis of the pipe interface 400 is perpendicular to the first direction. In such a layout, when the oil receiving box 110 is installed on the machine tool, the axis of the pipe interface 400 connected to the second cavity 112 is parallel to the horizontal plane, which is more convenient for the connection between the first hose 120 and the pipe interface 400.
[0032] In some specific embodiments of the present application, the distance between the bottom wall of the first cavity 111 of any oil receiving box 110 and the oil storage tank 200 in the first direction is the third distance. From the circumferential side wall of the first cavity 111 to the direction of the communication hole 113, the third distance gradually decreases, and the distance between the bottom wall of the first cavity 111 corresponding to the communication hole 113 and the oil storage tank 200 is the smallest. That is to say, the communication hole 113 is located at the lowest position of the bottom wall of the first cavity 111. The lubricating oil dripping into the first cavity 111 can flow towards the communication hole 113 under the action of gravity, and finally enter the second cavity 112 through the communication hole 113, further avoiding the accumulation of lubricating oil on the bottom wall of the first cavity 111 and reducing the probability of the lubricating oil splashing outside the oil receiving box 110.
[0033] The oil receiving boxes 110 are interconnected through the first hoses 120. The installation positions of the oil receiving boxes 110 are determined according to the positions where the lubricating oil will drip on the machine tool. Therefore, multiple oil receiving boxes 110 are not necessarily installed on the same horizontal plane. In some embodiments of the present application, the distance between any oil receiving box 110 and the oil storage tank 200 is the first distance, and the distance between the oil receiving box 110 connected to the second hose 300 and the oil storage tank 200 is the second distance, and the second distance is less than or equal to the first distance.
[0034] When multiple oil receiving boxes 110 are at different height positions, the distance between the oil receiving box 110 connected to the second hose 300 and the oil storage tank 200 is the closest. That is to say, this oil receiving box 110 is located at the lowest position among all the oil receiving boxes 110. The lubricating oil in all the oil receiving boxes 110 will flow towards this oil receiving box 110 under the action of gravity. Connecting this oil receiving box 110 to the second hose 300 can enable the lubricating oil in the oil receiving assembly to flow smoothly into the oil storage tank 200, improving the smoothness of the lubricating oil flow.
[0035] When multiple oil receiving boxes 110 are at the same height position, the second distance is equal to the first distance, and the second hose 300 can be connected to any first hose 120.
[0036] The oil storage tank 200 is located below the oil receiving assembly, and the second hose 300 is connected to the circumferential side wall of the oil storage tank 200. The interface of the oil storage tank 200 for connecting the second hose 300 is arranged at its circumferential side wall, which is more convenient for the operator to connect the second hose 300. Moreover, connecting the second hose 300 to the circumferential side wall of the oil storage tank 200 can also save the installation space of the recovery device. If the second hose 300 is connected to the top of the oil storage, when installing the oil storage tank 200, it is necessary to note that a certain space needs to be reserved at the top of the oil storage tank 200 to ensure that the second hose 300 can be smoothly connected to the top of the oil storage tank 200.
[0037] In some preferred embodiments of the present application, referring to Figure 2 and Figure 3 as shown, a transition pipe section 500 is installed on the circumferential side wall of the oil storage tank 200. One end of the transition pipe section 500 communicates with the oil storage cavity, and the other end is used to connect the second hose 300. Moreover, the plane where the axis of the transition pipe section 500 is located is perpendicular to the first direction. That is to say, when the oil storage tank 200 is installed at a suitable position on the machine tool, the transition pipe section 500 is located on the horizontal plane, and the interface axis of the second hose 300 and the transition pipe section 500 is also located on the horizontal plane. In such a layout, the height difference requirement between the oil receiving box 110 connected to the second hose 300 and the oil storage tank 200 is not high. If the transition pipe section 500 is arranged vertically, the interface axis of the transition pipe section 500 and the second hose 300 is also arranged vertically. In this layout, the height difference requirement between the oil receiving box 110 connected to the second hose 300 and the oil storage tank 200 is relatively high. Moreover, by arranging the transition pipe section 500 horizontally, even if the length of the second hose 300 is relatively long, the second hose 300 is not prone to bending, and it is not easy for lubricating oil to accumulate in the second hose 300 and fail to flow into the oil storage tank 200 in time.
[0038] The oil storage tank 200 is also equipped with an oil drain valve 600. Referring to Figure 1 and Figure 3 as shown, the oil drain valve 600 is used to discharge the lubricating oil located in the oil storage cavity. When oil drainage is not required, the oil drain valve 600 is closed, and when oil drainage is required, the oil drain valve 600 is opened for oil drainage.
[0039] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
