Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of mechanical equipment, in particular to a water-cooled spindle for a machining center. Background Art
[0002] In modern machining, machining centers are increasingly widely used. During the machining process, a large amount of heat is generated due to high-speed cutting of the tool. If it cannot be cooled in time and effectively, it will lead to accelerated tool wear, reduced machining accuracy, and even affect the service life of the tool and machining quality. A water-cooled spindle for a machining center is required to cool the tool and discharge the waste generated during drilling but remaining in the hole. However, the existing water-cooled spindle technology for machining centers has exposed certain defects in practical applications.
[0003] For the traditional water-cooled spindle of a machining center, there are obvious deficiencies in the cooling method of the tool. During the machining process, the cooling water ejected from the tool cooling port will carry the waste and eject from the drilling hole, often remaining on the surface of the workpiece. If these residual waste waters mixed with chips and impurities are not cleaned in time, it will affect the subsequent machining process and product quality. But the existing cleaning methods usually wipe manually or use external cleaning equipment after machining is completed. This method is not only inefficient, increasing labor costs, but also difficult to ensure the thoroughness and consistency of cleaning; in addition, the connection tightness between the tool and the spindle is also an urgent problem to be solved. Under the action of long-term high-speed rotation and high-pressure cooling liquid, the existing connection method is prone to looseness and sealing failure, resulting in liquid leakage. Liquid leakage will not only cause waste of cooling liquid and increase production costs, but also may corrode and damage the internal structure and electrical components of the machining center, affecting the normal operation and service life of the equipment.
[0004] Therefore, it is necessary to provide a water-cooled spindle for a machining center to solve the above technical problems. Summary of the Utility Model
[0005] The utility model provides a water-cooled spindle for a machining center, which solves the problems that the waste water on the surface of the workpiece cannot be cleaned in time and the seal between the tool and the spindle fails after long-term operation.
[0006] To solve the above technical problems, a water-cooled spindle for a machining center provided by the utility model includes: a spindle, a cooling chamber is arranged at the top of the spindle, a valve body is arranged at the bottom of the cooling chamber, a water outlet pipe is opened inside the spindle, a tool mounting block is fixedly connected to the bottom of the spindle, a tool is mounted on the tool mounting block, a clamping column is arranged on the tool, a connecting pipe is fixedly connected to the top of the clamping column, a tool head is fixedly connected to the bottom of the clamping column, two shunt pipes are opened inside the tool head, a cleaning mounting block is fixedly connected to the lower part of the spindle surface, a cleaning pipe is opened inside the cleaning mounting block, and a cleaning head is mounted on the cleaning mounting block.

[0012] Compared with the related art, a water-cooled spindle for a machining center provided by the utility model has the following beneficial effects:
[0013] A cleaning head is installed at the clamping position between the spindle and the tool, which can clean the surface of the workpiece in real time during the machining process. This not only ensures the cleanliness of the machining surface, improves the quality of the workpiece, but also avoids the subsequent cumbersome cleaning process. For example, when machining some precision parts with extremely high surface quality requirements, timely surface cleaning can ensure that there is no impurity residue on the surface of the parts, eliminating the need for additional manual cleaning, greatly improving the production efficiency and product qualification rate; and the tool can be tightly connected to the spindle, preventing the occurrence of liquid leakage.

Specific embodiments
[0019] The present utility model will be further described below in conjunction with the accompanying drawings and embodiments.
[0020] Please refer to in conjunction with Figure 1 , Figure 2 , Figure 3 , Figure 4 , wherein, Figure 1 Schematic structural diagram of a preferred embodiment of a water-cooled spindle for a machining center provided by the present utility model; Figure 2 For Figure 1 Partial structural diagram of the lower part of the spindle surface shown; Figure 3 For Figure 1 Partial sectional view of the lower part of the spindle surface shown; Figure 4 For Figure 3Schematic enlarged view of part A shown. A water-cooled spindle of a machining center includes: a spindle 1, a cooling chamber 2 is provided at the top of the spindle 1, a valve body 3 is provided at the bottom of the cooling chamber 2, a water outlet pipe 4 is opened inside the spindle 1, a tool mounting block 5 is fixedly connected to the bottom of the spindle 1, a tool 6 is mounted on the tool mounting block 5, a clamping column 7 is provided on the tool 6, a connecting pipe 8 is fixedly connected to the top of the clamping column 7, a tool tip 9 is fixedly connected to the bottom of the clamping column 7, two shunt pipes 10 are opened inside the tool tip 9, a cleaning mounting block 12 is fixedly connected to the lower part of the surface of the spindle 1, a cleaning pipe 11 is opened inside the cleaning mounting block 12, and a cleaning head 13 is mounted on the cleaning mounting block 12. The device installs the cleaning head 13 at the clamping position between the spindle 1 and the tool 6, and can clean the surface of the workpiece in real time during the machining process. This not only ensures the cleanliness of the machining surface, improves the quality of the workpiece, but also avoids subsequent cumbersome cleaning processes.
[0021] A threaded sleeve 14 is provided on the tool 6, the threaded sleeve 14 is threadedly connected to the tool mounting block 5, a rotating disk 15 is fixedly connected to the bottom of the threaded sleeve 14, a rotating ring 16 is fixedly connected inside the threaded sleeve 14, an adapter disk 17 is fixedly connected to the surface of the clamping column 7, a coupling groove 18 is opened inside the clamping column 7, a coupling rod 19 is fixedly connected inside the tool mounting block 5, and a sealing gasket 20 is fixedly connected inside the tool mounting block 5. Rotate the rotating disk 15, the threaded sleeve 14 moves deeper into the tool mounting block 5 through threaded connection, driving the clamping column 7 to move deeper until the coupling rod 19 enters the coupling groove 18, the top of the clamping column 7 is closely attached to the sealing gasket 20, and the threaded sleeve 14 and the clamping column 7 are rotationally connected through the rotating ring 16 and the adapter disk 17. When the tool tip 9 rotates through the spindle 1 to machine the workpiece, since the threaded sleeve 14 is rotationally connected to the clamping column 7 and the threaded sleeve 14 does not bear the stress generated by the machined workpiece, it can ensure that the top of the clamping column 7 always closely adheres to the sealing gasket 20 and no liquid leakage will occur.
[0022] A driving mechanism 21 is provided on the spindle 1, and a bushing 28 is fixedly connected to the spindle 1. The bushing 28 can prevent the spindle 1 from directly contacting and rubbing against other components, thereby reducing the wear of the spindle 1 itself and extending the service life of the spindle 1.
[0023] A first cooling pipe 22 is fixedly connected to the top of the cooling chamber 2, and the other end of the first cooling pipe 22 is fixedly connected to a pump body 23. The pump body 23 can increase the pressure of the coolant, making its cleaning ability stronger.
[0024] The pump body 23 is fixedly connected to a second cooling pipe 24 at the bottom, and the other end of the second cooling pipe 24 is fixedly connected to an exchange tank 25. The exchange tank 25 cools down the coolant by exchanging heat with the cooling medium.
[0025] A filter 26 is installed on the top of the exchange box 25. An injection pipe 27 is fixedly connected to the filter 26. Before the coolant enters the exchange box 25, it will enter the filter 26, and the filter screen inside the filter 26 will filter the impurities in the coolant.
[0026] The working principle of a water-cooled spindle for a machining center provided by the present utility model is as follows:
[0027] When the valve body 3 is opened, the coolant in the cooling chamber 2 will enter the connecting pipe 8 in the tool 6 through the water outlet pipe 4, and then be ejected from the tool tip 9 through the shunt pipe 10. While cooling the tool tip, it can also eject the drilling waste out of the hole when drilling at the tool tip 9. At the same time, the cleaning pipe 11 is connected to the water outlet pipe 4. After the drilling waste is ejected and spread on the surface of the workpiece along with the coolant, opening the water valve on the cleaning head 13 can eject liquid to clean the surface of the workpiece in real time, which can not only ensure the cleanliness of the workpiece, but also avoid subsequent cumbersome cleaning processes.
[0028] Compared with the related art, a water-cooled spindle for a machining center provided by the present utility model has the following beneficial effects:
[0029] A cleaning head 13 is installed at the clamping connection between the main shaft 1 and the tool 6 of the device, which can clean the surface of the workpiece in real time during the machining process. This not only ensures the cleanliness of the machining surface, improves the quality of the workpiece, but also avoids subsequent cumbersome cleaning processes. For example, when machining some precision parts with extremely high surface quality requirements, timely surface cleaning can ensure that there is no impurity residue on the surface of the parts, eliminating the need for additional manual cleaning, greatly improving the production efficiency and product qualification rate; and the tool 6 can be tightly connected to the main shaft 1, preventing the occurrence of liquid leakage. On the one hand, this avoids the waste of cooling liquid and reduces the production cost; on the other hand, it also prevents the damage of the leaked liquid to the electrical components and mechanical structures inside the machining center, reducing the equipment maintenance and repair costs.
