Description

Technical Field

[0001] The utility model belongs to the field of milling processing, and particularly relates to a cooling structure for a diamond tool used in milling processing. Background Art

[0002] Milling processing is a metal cold processing method. The blank is fixed, and a high-speed rotating milling cutter is used to feed on the blank to cut out the required shapes and features. Traditional milling is mostly used for simple external shape features such as milling contours and grooves.

[0003] There is a existing cooling structure for a tool used in milling machine steel processing (CN220783205U). By setting a water flow driving component, a gear ring, a torsion spring and a liquid spraying component, the liquid impacts the water flow driving component to move, so that the water flow driving component cooperates with the torsion spring to drive the gear ring to rotate reciprocally, and the liquid spraying component rotates reciprocally, so that the liquid spraying component can evenly spray the cooling liquid around the tool head to avoid cooling dead angles. However, in the actual use process, due to the fact that the torsion spring will gradually generate fatigue after long-term use, phenomena such as slow reset and improper reset position of the liquid spraying component will occur, affecting the use. Moreover, each time of reset, noise will be generated due to the collision of the reset components. At the same time, since a certain pulling force is required when the torsion spring is stretched, using the method of liquid impacting the water flow driving component to provide power is not only difficult to stretch the torsion spring but also the reciprocating rotation efficiency of the liquid spraying component is poor, affecting the actual use effect. Therefore, a cooling structure for a diamond tool used in milling processing is proposed to solve the above-mentioned problems. Content of the Utility Model

Detailed implementation manners

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1-3 , in the diamond tool cooling structure for milling in this embodiment, compared with the prior art, since the universal nozzle 47 can rotate around the cutter head 1 without the torsion spring reset, not only will the effect not be weakened due to the fatigue of the torsion spring, but also the rotation efficiency is higher and the use effect is better.

[0022] Specifically, it includes a cutter head 1;

[0023] A fixing bracket 2 sleeved on the outer wall of the cutter head 1;

[0024] A mounting plate 3 arranged on the upper part of the outer wall of the fixing bracket 2;

[0025] A rotary spraying assembly 4 arranged on the lower part of the outer wall of the fixing bracket 2 for spraying coolant onto the cutter head 1;

[0026] A driving and conveying assembly 5 arranged below the mounting plate 3 and connected to the front and rear sides of the mounting plate 3. The driving and conveying assembly 5 is connected to the rotary spraying assembly 4 for driving the rotary spraying assembly 4 to rotate and conveying coolant;

[0027] A micro servo motor 6 arranged on the top of the mounting plate 3. The micro servo motor 6 is connected to the driving and conveying assembly 5.

[0028] In this embodiment, when in use, the driving and conveying assembly 5 can be first connected to an external coolant conveying pipe. When the cutter head 1 is in use, the micro servo motor 6 is powered on and started, and the rotary spraying assembly 4 is rotated through the driving and conveying assembly 5. The external coolant enters the rotary spraying assembly 4 after entering the driving and conveying assembly 5 and is evenly sprayed on the cutter head 1 by the rotary spraying assembly 4 while rotating, thereby avoiding cooling dead angles and improving the cooling effect and efficiency.

[0029] Specifically, referring to Figures 1-3 Figures 1-3 , the rotary spraying assembly 4 includes a bearing support 41 sleeved on the lower outer wall of the fixed frame 2; a water spraying frame 42 sleeved on the outer wall of the bearing support 41, and the water spraying frame 42 is in a ring-shaped U-shaped structure; two sealing bearings I 43 arranged on the inner wall edge of the water spraying frame 42; a rotating ring 44 arranged on the inner walls of the two sealing bearings I 43, and the rotating ring 44 is rotatably arranged inside the water spraying frame 42 and realizes rotary sealing through the two sealing bearings I 43; a connecting pipe 45 communicated with the outer wall of the rotating ring 44, and one end of the connecting pipe 45 far from the rotating ring 44 penetrates through the water spraying frame 42; a gear ring 46 arranged on the top of the water spraying frame 42; two universal spray pipes 47 symmetrically arranged below the water spraying frame 42.

[0030] In this embodiment, when the gear ring 46 is driven to rotate, the water spraying frame 42 and the two universal spray pipes 47 can be driven to rotate in sequence. Through the two sealing bearings I 43, the rotating ring 44 remains unchanged to maintain the connection state with the connecting pipe 45. When the external coolant is conveyed to the inside of the water spraying frame 42 through the connecting pipe 45, it can be continuously conveyed to the inside of the two universal spray pipes 47 and sprayed on the tool bit 1 through them. Since the universal spray pipes 47 rotate around the tool bit 1 during the spraying process, the coolant is evenly sprayed on the tool bit 1, avoiding dead angles and improving the cooling effect and efficiency. Compared with the prior art, since the universal spray pipes 47 can rotate around the tool bit 1 without a torsion spring reset, not only the effect will not be weakened due to the fatigue of the torsion spring, but also the rotation efficiency is higher and the use effect is better.

[0031] Specifically, referring to Figures 1-3 Figures 1-3 , the driving and conveying assembly 5 includes a pressurizing frame 51 located below the mounting plate 3 and communicated with the connecting pipe 45; two connecting frames 52 respectively arranged on the front and rear sides of the pressurizing frame 51, and the pressurizing frame 51 is fixed on the mounting plate 3 through the two connecting frames 52; a rotating rod 53 arranged below the mounting plate 3, and the top end of the rotating rod 53 penetrates through the mounting plate 3 and is connected to the output end of the micro servo motor 6; a gear 54 arranged on the outer wall of the rotating rod 53, and the gear 54 meshes with the gear ring 46. A water inlet pipe 55 is communicated with one side of the outer wall of the pressurizing frame 51 far from the connecting pipe 45.

[0032] In this embodiment, when the micro servo motor 6 is powered on and started, the rotating rod 53 rotates accordingly and drives the gear 54 to rotate to drive the gear ring 46. Before use, the external coolant conveying pipe needs to be connected to the water inlet pipe 55. When the coolant enters the inside of the pressurizing frame 51 through the water inlet pipe 55, the coolant will be conveyed to the inside of the water spraying frame 42 through the connecting pipe 45 under the action of the water flow.

[0033] Specifically, referring to Figure 3, the lower end of the rotating rod 53 penetrates through the pressurizing frame 51 and extends into the interior of the pressurizing frame 51. The rotating rod 53 is rotationally sealed with the pressurizing frame 51 through the second sealing bearing 7. A pressurizing blade 8 is provided at the lower end of the rotating rod 53, which can be used to increase the conveying pressure of the coolant.

[0034] In this embodiment, when the rotating rod 53 rotates, it can drive the pressurizing blade 8 to rotate. When the pressurizing blade 8 rotates, it can pressurize the water flow (prior art), and then improve the cooling efficiency of the tool head 1 by increasing the water flow rate.

[0035] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
