[0029] Example

[0030] See appendix Figure 1 , 2 As shown in Figures 3 and 4, a high-pressure water-cooled chip removal device for a lathe includes a spindle 2. A central through hole 21 is provided on the spindle 2 along its axis. The other structures of the spindle 2 are existing technologies, and existing power sources such as motors and reducers drive the spindle 2 to rotate. In addition, a water outlet mechanism is provided in the central through hole 21 to flush away the chips cut from the inner hole of the workpiece 1.

[0031] See Figure 5 , 6 As shown, the water outlet mechanism includes a fixed flange 3, a flushing pipe 4, a support wheel 5, a sealing ring 51, a nozzle 6, a protective plate 7, an adjusting sleeve 8, a rotary joint 9, and a high-pressure water outlet device.

A flushing pipe 4 is fixedly inserted into the flange through hole 31. The flushing pipe 4 can be connected to the fixed flange 3 by welding. Of course, provided that the sealing between the inner wall of the flange through hole 31 and the outer circumference of the flushing pipe 4 is ensured, the flushing pipe 4 can also be threaded into the flange through hole 31.

[0033] The flushing pipe 4 is arranged in the central through hole 21, so the outer diameter of the flushing pipe 4 is smaller than the inner diameter of the central through hole 21. A support wheel 5 is fixedly sleeved on the outer circumference of the flushing pipe 4 in the central through hole 21, and the support wheel 5 can be provided with a plurality of support wheels 5, and in the embodiment, the support wheel 5 is provided with two support wheels 5. The flushing pipe 4 is made of metal, and when the support wheel 5 is made of metal, the support wheel 5 can be welded on the flushing pipe 4, and when the support wheel 5 is made of non-metal material, the support wheel 5 can be bonded on the flushing pipe 4. In the embodiment, in order to realize the sealing between the support wheel 5 and the inner circumference of the central through hole 21, and at the same time, in order to realize the support of the flushing pipe 4, a ring groove is formed on the outer circumference of the support wheel 5, and a sealing ring 51 is fixedly embedded in the ring groove, and the sealing ring 51 can be made of elastic rubber material.

[0034] In order to facilitate the fixation of the flushing pipe 4, a plurality of flange counterbores 32 are uniformly formed on the fixing flange 3, and the fastening bolts 33 are arranged in the flange counterbores 32 and are threadedly connected to the end face of the main shaft 2. In the embodiment, in order to adjust the position of the flushing pipe 4 in the axial direction and then fix the flushing pipe 4, a detachable adjusting sleeve 8 is arranged between the fixing flange 3 and the main shaft 2, that is, the fastening bolts 33 are sequentially arranged in the flange counterbores 32 of the fixing flange 3, the adjusting sleeve 8 and are threadedly connected in the main shaft 2 to fix the fixing flange 3 to the main shaft 2. In actual work, the adjusting sleeve 8 with a corresponding length can be replaced according to the length of the nozzle 6 extending into the workpiece 1. Of course, as shown in the figure, the adjusting sleeve 8 can not be arranged, and the fixing flange 3 is directly connected to the main shaft 2, and at this time, the length of the flushing pipe 4 and the nozzle 6 extending out of the central through hole 21 is the longest. Therefore, the installation or removal of the adjusting sleeve 8 with different lengths or the installation of the adjusting sleeve 8 can be performed according to the work requirements. Figure 8

[0035] Further, a limiting groove 35 is formed on the side end face of the fixing flange 3 facing the main shaft 2, the limiting groove 35 is coaxially arranged with the adjusting sleeve 8, and the adjusting sleeve 8 can be embedded in the limiting groove 35.

[0036] In order to further realize the support of the flushing pipe 4 and avoid the cutting chips from entering the central through hole 21, the protective plate 7 is detachably fixedly connected to the end of the main shaft 2 away from the fixing flange 3 through the bolt, the guide boss 71 is integrally and fixedly connected to the outer side end face of the protective plate 7, the guide through hole 72 is coaxially formed on the protective plate 7 and the guide boss 71, the guide through hole 72 is coaxially arranged with the central through hole 21, the flushing pipe 4 is slidably arranged in the guide through hole 72 and extends to the outside of the guide boss 71, and the nozzle 6 is fixedly connected to the flushing pipe 4 outside the guide boss 71.

[0037] ​Specifically, the nozzle 6 can be welded on the flushing pipe 4, or can be detachably fixed and installed on the flushing pipe 4 through a threaded connection. The front end of the nozzle 6 is a conical structure with an internal hollow structure, and a water spraying through hole 61 is formed in the front end and the conical surface of the conical structure. Of course, the nozzle 6 can also have other existing structures, as long as it can be fixed and installed on the flushing pipe 4 and can spray cutting fluid into the inner hole of the workpiece 1 through the flushing pipe 4 and the nozzle 6.

[0038] A connecting pipe 34 is fixedly connected to the end of the fixing flange 3 away from the main shaft 2 by welding, the connecting pipe 34, the flange through hole 31 and the flushing pipe 4 are coaxially arranged and communicate with each other; the water outlet of the rotary joint 9 is detachably fixed and connected to the connecting pipe 34 through a threaded connection, and the water inlet of the rotary joint 9 is connected to a high-pressure water outlet device (not shown in the figure). Specifically, the rotary joint 9 can be selected from the existing DEUBLIN brand rotary joint, and the high-pressure water outlet device is a prior art. The cutting fluid in the liquid storage tank storing the cutting fluid is pumped into the rotary joint 9, the flushing pipe 4 and the nozzle 6 through a filtering device by a high-pressure pump.

[0039] The working principle and process of the embodiment are as follows:

[0040] The process of installing the chip removal device is as follows: the flushing pipe 4 is inserted into the center through hole 21 from one end together with the support wheel 5 and the sealing ring 51 on it, the corresponding length of the adjusting sleeve 8 is embedded in the limiting groove 35, the fastening bolt 33 is arranged in the flange counterbore 32 and the adjusting sleeve 8 and is threadedly connected to the end face of one end of the main shaft 2, so as to fixedly install the fixing flange 3 and the adjusting sleeve 8 on the main shaft 2; the protective plate 7 is sleeved on the flushing pipe 4 at the other end of the main shaft 2 and is fixedly installed on the end face of the main shaft 2 by bolts, the nozzle 6 is installed on the flushing pipe 4 outside the guide boss 71, and the three-jaw chuck 22 is installed on the main shaft 2; the water outlet of the rotary joint 9 is threadedly connected in the connecting pipe 34, and the water inlet of the rotary joint 9 is communicated with the high-pressure water outlet device.

[0041] When machining the inner hole of the workpiece 1 with the same inner diameter in the axial direction, as shown in Figure 3 , the nozzle 6 is arranged inside the inner side of the end face of the workpiece 1 to avoid interference with the cutting tool;

[0042] When machining the inner hole of the workpiece 1 with different inner diameters in the axial direction, as shown in Figure 8 , the nozzle 6 needs to be inserted into the workpiece 1 by a certain length to effectively flush the inner circumference to be machined. At this time, the corresponding length of the adjusting sleeve 8 can be replaced according to the length of the flushing pipe 4 and the nozzle 6 inserted into the inner hole of the workpiece 1. After replacing the adjusting sleeve 8 and tightening the fastening bolt 33, the fixing flange 3 pushes the flushing pipe 4, the support wheel 5, the sealing ring 51 and the nozzle 6 into the inner hole of the workpiece 1 under the guidance of the guide through hole 72;

[0043] Of course, it needs to be explained that when there is no workpiece with different processing inner diameter, the adjusting sleeve 8 can not be installed, at this time, the fixed flange 3 is directly connected with the main shaft 2, and the nozzle 6 is arranged on the inner side of the inner side end face of the workpiece 1.

[0044] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
