[0002] The tool changer of a machining center is a mechanical device used to automatically change tools during machining. It is usually located in the spindle part of the machining center and can quickly and accurately change the required tools between different processes.

[0003] However, in the prior art, since the surface of the tool will inevitably wear out during long-term use, in order to ensure that the tool can continue to maintain a good working condition, the staff needs to manually oil the tool regularly to maintain its lubricity, but the manual oiling operation process is relatively cumbersome and requires the staff to spend a certain amount of time and energy to complete, which not only reduces work efficiency but also increases the staff's workload. Secondly, since the blade of the tool is usually very sharp, during the oiling process, the hand can easily come into contact with the tool and cause injury, which not only poses a threat to the health of the staff, but also reduces the safety of the equipment. Therefore, we provide a tool changing device for a machining center. Utility Model Content

The two sides of the bracket 18 are respectively fixedly connected to the inner walls of the mounting groove 14. The bottom of the downward pressure cylinder 19 is docked at the top of the bracket 18. A channel plate 110 is provided at the bottom of the downward pressure cylinder 19. Oil-absorbing cotton 112 is provided on both sides of the inner wall of the channel plate 110. An oil pipe 113 is provided on one side of the top of the channel plate 110. The output end of the downward pressure cylinder 19 passes through the bracket 18 and the top of the channel plate 110. Fixedly connected, oil-absorbing cotton 112 is fixedly connected on both sides of the inner wall of the channel plate 110, one end of the oil pipe 113 is connected to the slot opened on one side of the top of the channel plate 110, an oil tank 114 is provided on the side of the top of the top plate 13 close to the mounting slot 14, the other end of the oil pipe 113 passes through the top plate 13 and is connected to the slot opened on one side of the oil tank 114, the bottom of the oil tank 114 is fixedly connected to the side of the top of the top plate 13 close to the mounting slot 14, and a cleaning mechanism 2 is provided on one side of the top of the base 11.

[0024] When the tool 32 is lubricated, the operator can start the motor 15 to move the tool 32 to the desired location. The operator can then start the motor 15 and the tool holder 17 to rotate slowly. When the tool holder 17 rotates, the tool 32 will pass through the channel plate 110 in sequence, and the oil-absorbing cotton 112 on both sides of the channel plate 110 will apply lubricating oil to the outer surface of the tool 32. The operator can start the downward pressure cylinder 19 to adjust the height of the channel plate 110 to ensure that each tool 32 can fully contact the oil-absorbing cotton 112 when moving. When the lubricating oil on the oil-absorbing cotton 112 needs to be replenished, the lubricating oil can be added to the oil tank 114. The lubricating oil will flow to the channel plate 110 through the oil pipe 113 and be added to the oil-absorbing cotton 112. Therefore, the tedious operation of manual oiling can be avoided, the workload of the operator can be reduced, and the operator's time and energy can be saved. At the same time, the operator can avoid contact between the hands and the tool 32 during the oiling process, thereby improving the safety of the equipment.

[0025] like Figure 1-Figure 4 As shown, the cleaning mechanism 2 includes a mounting seat 21, the bottom of the mounting seat 21 is fixedly connected to one side of the top of the base 11, the two sides of the inner wall of the mounting seat 21 are respectively fixedly connected to the two sides of the connecting plate 22, and a brush 23 is fixedly connected to one side of the connecting plate 22 close to the tool holder disc 17.

[0026] In this embodiment, after each use of the tool 32, foreign debris will be generated on its surface, and then during the rotation of the tool holder disc 17, the surface of these tools 32 will come into contact with the brush 23, and then the foreign debris on the surface of the tool 32 can be cleaned to ensure the cleanliness of the tool 32, while reducing the wear on the surface of the tool 32, extending the service life of the tool 32, and facilitating subsequent oiling operations.

[0027] The utility model provides a tool changing device for a machining center, and the specific working principle is as follows:

[0028] When the staff needs to use the device to oil the tool 32, the slow motor 15 in the device is started to drive the rotating rod 16 and the tool holder disc 17 to rotate slowly and steadily. When the tool holder disc 17 starts to rotate, the tools 32 fixed on the tool holder disc 17 will move to the position of the channel plate 110 one by one according to the set sequence. When the tools 32 pass through the channel plate 110, these oil-absorbing cottons 112 will apply a uniform layer of lubricating oil to the outer surface of the tools 32. In order to ensure that each tool 32 can fully contact with the oil-absorbing cotton 112, the staff can start to adjust the height of the channel plate 110. Ensure that the contact between the tool 32 and the oil-absorbing cotton 112 reaches the best state. As the lubrication operation proceeds, the lubricating oil on the oil-absorbing cotton 112 will gradually decrease. At this time, the staff only needs to pour new lubricating oil into the oil tank 114. The oil tank 114 and the channel plate 110 are connected by an oil pipe 113, so the lubricating oil will automatically flow to the channel plate 110 to replenish the lubricating fluid for the oil-absorbing cotton 112 to ensure that the lubrication operation can continue. In addition, when the tool holder disc 17 rotates, the surface of these tools 32 will contact the brush 23, so that the impurities and debris on the surface of the tool 32 can be cleaned.

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
