[0001] The utility model relates to the technical field of lathe turrets, in particular to a high-pressure cooling water device for a lathe turret. Background Art

[0002] The lathe turret is one of the most important production tools in the functional components of a lathe. Since the contact between the cutting tool of the lathe turret and the product to be processed is a hard contact, a large amount of heat will be generated at the positions of the cutting tool and the product during processing. In order to increase the service life of the cutting tool, cooling water is often sprayed at the cutting point of the cutting tool to cool the cutting tool. In the traditional cooling water device, the water inlet is usually arranged at the bottom side around the tool disc, and the water outlet is arranged outside the tool disc. The problem with directly arranging the water inlet of the cooling water on the tool disc is that the related components are easily worn, which affects water inlet and cooling. The cooling water pressure that can be borne is only 5 to 40 Bar. If 70 Bar high-pressure cooling water is used, it may cause component damage and failures. In addition, the traditional cooling water device often has varying degrees of water leakage, which will cause a large amount of cooling water to be lost, unable to smoothly carry out the cutting tool cooling operation, and also easily cause difficulties in maintenance work.

[0003] Therefore, there is an urgent need in the current industry to seek a high-pressure cooling water device for a lathe turret that can avoid damage to the cooling water device and prevent water leakage, so as to solve various difficulties and deficiencies encountered in the above-mentioned prior art.

Moreover, unless clearly excluded from a specific context in the present utility model, the singular article also includes the description of multiple components or elements.

[0043] As described in the background art, the direct setting of the water inlet of the currently known traditional cooling water device on the tool turret will cause the relevant components to be easily worn, affecting water intake and cooling. At the same time, it cannot withstand the operation of high-pressure cooling water, and there is a problem of cold water leakage. To solve the above technical problems, the basic idea of the present utility model is to provide a high-pressure cooling water device for a lathe tool turret. By changing the position of the water inlet, the relevant components can be made not easily worn, and it can withstand the operation of high-pressure cooling water. A brass bushing with a function equivalent to a piston is adopted, which can effectively reduce the phenomenon of cooling water leakage.

[0044] Please refer to Figures 1 through 5 。 Figure 1 is a sectional view of the high-pressure cooling water device for a lathe tool turret provided by the embodiment of the present utility model; Figure 2 is a three-dimensional sectional view of the high-pressure cooling water device for a lathe tool turret provided by the embodiment of the present utility model from the left front angle; Figure 3 is a three-dimensional sectional view of the high-pressure cooling water device for a lathe tool turret provided by the embodiment of the present utility model from the left rear angle; Figure 4 is a partial enlarged view of the brass bushing of the high-pressure cooling water device for a lathe tool turret provided by the embodiment of the present utility model; Figure 5 is an external view of the high-pressure cooling water device for a lathe tool turret provided by the embodiment of the present utility model. The high-pressure cooling water device 100 of this embodiment is mainly composed of a tool turret 10, a water pan 20, a water ring 30, and a brass bushing 40.

[0045] Among them, a plurality of tool positions 11 are provided on the cutter head 10, and a plurality of cooling water channels 12 are provided inside the cutter head 10. Each cooling water channel 12 communicates with the corresponding tool position 11, and the water outlet 13 of each cooling water channel 12 is opened on the outer side of the cutter head 10. An opening 14 is provided at the center of the cutter head 10.

[0046] The water tray 20 is fixed in the opening 14 at the center of the cutter head 10 and rotates together with the cutter head 10. A plurality of first flow channels 21 are provided inside the water tray 20, and each first flow channel 21 communicates with the corresponding cooling water channel 12 inside the cutter head 10. A rotating groove 22 is recessed on the bottom side of the water tray 20.

[0047] The water ring 30 is embedded in the rotating groove 22 on the bottom side of the water tray 30. The water ring 30 remains fixed and does not rotate when the water tray 20 and the cutter head 10 rotate. That is to say, the water tray 20 and the cutter head 10 will rotate relative to the water ring 30. A plurality of second flow channels 31 are provided inside the water ring 30, and each second flow channel 31 communicates with the corresponding first flow channel 21 inside the water tray 20. The water inlet 32 of the second flow channel 31 is opened at the bottom of the water ring 30. A bushing hole 33 is recessed inside the water ring 30.

[0048] The brass bushing 40 is embedded in the water ring 30 and covers the periphery of the second flow channel 31, and the brass bushing 40 fits on the contact surface between the water ring 30 and the water tray 20. In the implementation of the present utility model, the brass bushing 40 is embedded in the bushing hole 33 of the water ring 30, and at least one bushing oil seal 41 is provided on the embedding surface of the brass bushing 40 in the bushing hole 33 to achieve the purpose of sealing; for example Figures 1 to 3 in, the number of the bushing oil seals 41 is two, but it is not limited to this in actual applications.

[0049] When the present utility model performs the cooling operation of high-pressure cooling water, the cooling water enters the second flow channel 31 of the water ring 30 from the water inlet 32 at the bottom of the water ring 30, then flows through the first flow channel 21 inside the water tray 20, and then flows into the cooling water channel 12 inside the cutter head 10. Finally, it flows out from the water outlet 13 on the outer side of the cutter head 10. Among them, the brass bushing 40 has the same function as a piston. Using the water pressure of the cooling water itself, the brass bushing 40 is pushed forward from the rear end of the brass bushing 40, so that the arc of the front end face of the brass bushing 40 fits the arc of the inner diameter of the water tray 20 to achieve sealing without leakage.

[0050] In the embodiment of the present utility model, at least one rotary oil seal 34 and 23 are respectively provided on the opposite sides of the rotating groove 22 of the water ring 30 and the water tray 20 with respect to the brass bushing 40, such as Figures 1 to 3In the [description], on both sides of the brass bushing 40 with the outer diameter of the water ring 30 and the inner diameter of the water pan 20, a rotary oil seal 34 and 23 are respectively provided as the second anti-leakage measure, so that the cooling water can be ejected from the water outlet 13 on the outer side of the tool turret 10 without leakage. The high-pressure cooling water device 100 of the lathe tool turret of the present utility model can be used with a cooling water pressure of up to 100 bar.

[0051] Furthermore, as Figure 4 shown, the brass bushing 40 of this embodiment is recessed with a positioning groove 43. An internal hexagon set screw 44 is provided on the side wall of the bushing hole 33 of the water ring 30, and the internal hexagon set screw 44 is locked into the positioning groove 43 to position the brass bushing 40 in terms of direction.

[0052] Here, the construction method of the brass bushing 40 of this embodiment is described in detail. To ensure that the outer diameter of the water ring 30 and the front end face of the brass bushing 40 have the same outer diameter dimension, the water ring 30 is first processed, and only a machining allowance of 0.05 mm is reserved on the outer diameter. The brass bushing 40 is first processed, and threads are tapped at both ends of the central through hole of the brass bushing 40, and only a machining allowance of 0.05 mm is reserved on the front end face. The brass bushing 40 is inserted into the water ring 30 and pushed to the bottom of the bushing hole 33. The internal hexagon set screw 44 is locked in from the front of the water ring 30, aligned with the positioning groove 43 of the brass bushing 40, and the brass bushing 40 is positioned in terms of direction. Then, from the other end of the outer diameter of the water ring 30, an internal hexagon socket screw 45 is locked in and tightened according to the standard locking torque of the screw to fix the brass bushing 40 to the water ring 30. The outer diameter of the water ring 30 and the brass bushing 40 are ground simultaneously with an outer diameter grinding machine (the grinding surface is Figure 4 the lower part of the water ring 30 and the brass bushing 40 in [description]) so that the brass bushing 40 and the water ring 30 have the same predetermined processed outer diameter dimension. After the processing is completed, the internal hexagon socket screw 45 is taken out.

[0053] According to the high-pressure cooling water device of the lathe tool turret provided by the present utility model, setting the water inlet at the bottom of the non-rotating water ring can make the related components of the water inlet not easily worn and will not affect the water inlet and cooling conditions. At the same time, it can withstand the operation of high-pressure cooling water, improve the cooling efficiency, and ensure the cutting performance and stability of the tool. Secondly, the brass bushing adopted in the present utility model has the same function as a piston. Using the water pressure of the cooling water itself, the brass bushing is pushed forward from the rear end of the brass bushing, so that the arc of the front end face of the brass bushing fits the arc of the inner diameter of the water pan, and leakage can be sealed. The present utility model can further set a rotary oil seal on both sides of the brass bushing with the outer diameter of the water ring and the inner diameter of the water pan, so that the cooling water can be ejected smoothly from the water outlet of the tool turret without leakage, which is more beneficial to the cooling operation of high-pressure cooling water.

After those skilled in the art have read the above content, various modifications and substitutions of the present utility model will be obvious. Therefore, the protection scope of the present utility model should be defined by the appended claims.
