Description

Technical Field

[0001] The utility model relates to the technical field of lubrication mechanisms, in particular to a lubrication mechanism for a numerically controlled machine tool. Background Art

[0002] CNC machine tools are characterized by high efficiency, high precision, high automation and high flexibility. They are the mainstream equipment in the contemporary machinery manufacturing industry. The application of CNC machining can greatly improve productivity, stabilize machining quality, shorten machining cycle, increase production flexibility, realize automated machining of various complex precision parts, and facilitate workshop management. When using CNC machine tools, it is necessary to propose a CNC machine tool lubrication mechanism.

[0003] When the lubrication mechanism in the prior art is fixedly installed between the lubrication cylinder and the lubrication block, the lubrication cylinder is generally fixedly installed by bolts and clamps. Although this method can also effectively fix the lubrication cylinder and the lubrication block, the installation process is time-consuming and labor-intensive, thereby reducing the installation efficiency of the lubrication mechanism and the lubrication efficiency of the lubrication mechanism for the CNC machine tool, and will greatly increase the workload of the staff. Moreover, the lubrication mechanism in the prior art cannot conveniently and effectively disassemble, replace or clean the filter plate. When the machine tool is oiled and lubricated, lubricating oil is required, but the lubricating oil often contains some impurities. At this time, a filter plate is required, but the filter plate will inevitably become clogged after long-term use. At this time, if the filter plate cannot be disassembled, replaced or cleaned, it will affect the filtering effect of the filter plate, thereby affecting the lubrication effect of the lubricating oil.

[0004] Compared with the Chinese patent with publication number CN216706890U, the utility model relates to the technical field of lubrication mechanism, and in particular to a lubrication mechanism for CNC machine tools, including a block and a shaft, wherein a matching hole matching with the shaft is provided in the middle of the block, and an oil tank is provided inside the block and at the bottom of the matching hole. The utility model stores lubricating oil by setting an oil storage bottle, and the lubricating oil in the oil storage bottle can flow into the oil tank through the oil channel. When the oil tank is full of lubricating oil, the oil channel will be covered to isolate the inside of the oil storage bottle from the outside world. Under the action of atmospheric pressure, the oil in the oil storage bottle will no longer flow out until the lubricating oil in the oil tank is consumed, the oil level drops, the oil channel is exposed, air enters the oil storage bottle, and the lubricating oil flows into the oil tank again, realizing the self-replenishment of the lubricating oil in the oil storage bottle, effectively ensuring the lubrication effect of the shaft-hole transmission parts, reducing the maintenance operation frequency, and intuitively understanding the lubrication status and replenishment by observing the oil storage bottle, without the need to regularly check the transmission parts, and conveniently grasping the maintenance time point.

[0005] The above scheme can very conveniently lubricate the machine tool, thereby effectively ensuring the lubrication effect of shaft hole type transmission parts, but the above scheme still uses bolts and clamps to fix the lubrication cylinder and the lubrication block. In addition, the above scheme cannot conveniently and effectively disassemble, replace or clean the filter plate, and fails to solve the problems raised in the above background technology.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] See also Figure 1 - Figure 8 As shown, this embodiment provides a lubrication mechanism for a CNC machine tool, including a lubrication block 1, and further comprising:

[0033] A screw rod 2 is threadedly connected to the interior of the lubricating block 1;

[0038] The reinforcing component is symmetrically arranged outside the oil injection component and is used to strengthen the fixing effect between the oil injection component and the lubricating block 1 .

[0039] The above working principle: when it is necessary to fix and install the oil filling component and the lubricating block 1, the oil filling component can be conveniently installed by installing the component, without the need for the staff to use tools such as bolts, thereby effectively improving the installation efficiency and oil filling efficiency of the oil filling component; when it is necessary to oil the lubricating block 1 and the screw 2, the oil filling component can be conveniently used to oil the lubricating block 1 and the screw 2; during the oil filling process of the oil filling component, the filter component can effectively intercept and filter the impurities contained in the lubricating oil, thereby effectively improving the quality of the lubricating oil; when it is necessary to disassemble and replace the parts inside the filter component, the parts inside the filter component can be conveniently disassembled by replacing the components, thereby effectively improving the filtering effect of the filter component; by strengthening the setting of the components, the fixing effect between the oil filling component and the lubricating block 1 can be further improved, thereby effectively improving the stability of the oil filling component, further improving the overall practicality of the device, saving time and effort.

When the lubricating block 1 and the screw 2 need to be lubricated with oil, it is only necessary to first add lubricating oil to the inside of the oiling cylinder 3 through the oiling pipe 11, and then press the pressing plate. 20 is pressed, at which time the pressing plate 20 will drive the connecting rod 19 to move synchronously, and the connecting rod 19 will drive the squeezing plate 21 to move synchronously. During the movement of the pressing plate 20, the return spring 22 will be squeezed, and the squeezing plate 21 will squeeze the lubricating oil inside the oil filling cylinder 3, and the squeezed lubricating oil will enter the lubricating block 1 through the filter assembly. At this time, the lubricating block 1 and the screw 2 can be effectively lubricated. When the lubrication is completed, the pressing plate 20 is released, and the return spring 22 is reset, driving the pressing plate 20, the connecting rod 19 and the squeezing plate 21 to reset and move synchronously, thereby facilitating the staff to carry out the next oiling process on the lubricating block 1 and the screw 2.

At this time, the lubrication block 1 and the screw 2 can be effectively lubricated. Through the setting of the sealing ring, the sealing between the oil inlet pipe 13 and the lubrication channel 10 can be effectively improved, thereby effectively improving the sealing between the oil filling assembly and the lubrication block 1.

When the fixed block 24 drives the plug rod 27 to move to the guide groove inside the positioning plate 9, the resistance spring 28 is reset, driving the plug rod 27 to move synchronously. When the plug rod 27 is inserted into the guide groove inside the positioning plate 9, the fixed block 24 can be fixed to the lubrication block 1.
