Description

Technical Field

[0001] The present application relates to the field of deep hole machining, and in particular to a deep hole machining lubrication device. Background Art

[0002] Deep hole machining is a manufacturing technique specifically designed for machining deeper holes. It usually involves the use of specialized tools such as deep hole drills, reamers, or grinding tools. Lubrication devices are mainly used to reduce cutting temperatures, reduce friction, and extend tool life during deep hole machining. Coolant is delivered directly to the cutting zone through a dedicated pump, and a high-pressure system is usually used to ensure adequate lubrication.

[0003] However, during deep hole processing, the drill bit will extend into a deeper area of ​​the hole. A cutting fluid nozzle is generally arranged around the existing drill bit, and the cutting fluid is sprayed into the hole through the nozzle through the pump body to increase the lubrication effect. However, the setting direction of the nozzle is generally consistent with the drilling direction of the drill bit, and is fixed. The sprayed cutting fluid is generally spread in a spraying manner. Some cutting fluid may not be accurately sprayed into the hole. In addition, during the drilling process of the drill bit, the opening distance between the nozzle and the hole surface is gradually approaching, which may cause the cutting fluid with a fixed spraying direction to be inconvenient to be accurately sprayed into the opening of the hole, thereby affecting the amount of cutting fluid entering the hole, and having a certain impact on the overall lubrication effect of the drill bit in the deep hole.

[0004] In view of the above-mentioned related technologies, the inventor believes that there is a defect in deep hole processing that the direction of the cutting fluid sprayed by the nozzle is difficult to adjust. Therefore, a deep hole processing lubrication device is proposed to solve the above problem. Utility Model Content

[0008] Preferably, the sliding mechanism includes several extension plates, which are integrally formed on the outer surface of the connecting plate. A screw is rotatably installed on the upper and lower ends of the inner wall of a single limit frame through the extension plate. The top end of the screw extends to the upper surface of the limit frame and a servo motor is installed. The upper and lower ends of the inner walls of the remaining multiple limit frames are welded with guide rods through the extension plate.

[0009] Preferably, the bottom of one side of the inner wall of the rack plate moves close to the outer surface of the gear, and the gear and the rack plate are engaged with each other.

[0020] The following is combined with Figure 1-5 This application is described in further detail.

[0021] The embodiment of the present application discloses a deep hole machining lubrication device. Figure 1-5 A deep hole processing lubrication device includes a drilling device 1, a drill bit 2 is provided at the middle of the bottom end of the drilling device 1, a fixing frame 3 is fixedly installed on the outer surface of the drilling device 1 near the drill bit 2, and a fixing groove 4 is equidistantly opened at the bottom end of the fixing frame 3. Spray heads 5 are installed at the front and rear ends of the inner wall of the fixing groove 4 through a rotating shaft. A box body for storing cutting fluid and a pump body for pumping the cutting fluid into the spray head 5 are also provided on the outer surface of the drilling device 1. The top of the spray head 5 is connected to the pump body through a hose. The pump body pumps the cutting fluid in the box body into multiple spray heads 5, so that the cutting fluid is The liquid is sprayed at the opening of the deep hole. Gears 6 are symmetrically welded on the outer surface of the spray head 5. A guide slide hole 7 is provided on one side of the top inner wall of the fixed groove 4. A rack plate 8 is movably installed inside the guide slide hole 7. The bottom of one side of the inner wall of the rack plate 8 is movable close to the outer surface of the gear 6. The gear 6 and the rack plate 8 are engaged with each other. The upper surface of the rack plate 8 extends to the top of the fixed frame 3 and is welded with a connecting plate 9. Several limit frames 10 are fixedly installed on the edge of the upper surface of the fixed frame 3. A sliding mechanism is also provided inside the limit frame 10 for adjusting the overall lifting and lowering activities of the connecting plate 9.

[0022] By starting the drilling equipment 1 and applying the drill bit 2 to the hole processing position, the drill bit 2 is extended into the hole for deep hole processing. When the drill bit 2 is extended to a certain depth in the hole, the movable connecting plate 9 drives the multiple rack plates 8 to move along the inside of the guide slide hole 7, so that the movable rack plate 8 drives the gear 6 to rotate, and the spray head 5 rotates synchronously with the gear 6, thereby adjusting the angle of the spray head 5, and adjusting the direction of the nozzle at the bottom end of the spray head 5 to different positions on the outer surface of the drill bit 2. When the drill bit 2 acts on a certain depth in the deep hole, the angle of the spray head 5 can be adjusted to spray the cutting fluid at the opening position of the hole, which reflects the adjustment effect of the cutting fluid spraying direction in the spray head 5.

[0023] Reference Figure 3-5The sliding mechanism includes several extension plates 11, which are integrally formed on the outer surface of the connecting plate 9. There are four limit frames 10, and the extension plates 11 are located inside the limit frames 10. The limit frames 10 and the extension plates 11 are embedded in each other. The upper and lower ends of the inner wall of a single limit frame 10 pass through the extension plates 11 and are rotatably installed with a screw rod 12. The top end of the screw rod 12 extends to the upper surface of the limit frame 10 and is installed with a servo motor 13. The upper and lower ends of the inner walls of the remaining multiple limit frames 10 pass through the extension plates 11 and are welded with guide support rods 14. A threaded hole is opened through the middle part of the top of a single extension plate 11, and one side of the outer surface of the screw rod 12 is located inside the threaded hole. A through hole is opened through the middle part of the top of the remaining multiple extension plates 11, and one side of the outer surface of the guide support rod 14 is located inside the through hole.

[0024] By starting the servo motor 13 to drive the screw rod 12 to rotate, the rotating screw rod 12 drives the connecting plate 9 and the extension plate 11 to move up and down along the outer surface of the limit frame 10, and at the same time, multiple guide rods 14 at different positions guide and support the moving connecting plate 9, keeping the connecting plate 9 in a stable lifting and lowering state on the outer surface of the limit frame 10, thereby improving the overall stability of the connecting plate 9 during movement and reflecting the overall lifting and lowering adjustment effect of the connecting plate 9.

When the drill bit 2 acts on a certain depth in the deep hole, the angle of the spray head 5 can be adjusted to spray the cutting fluid at the opening position of the hole. Compared with the existing technology, this solution has the effect of facilitating the spraying of cutting fluid at different positions on the outer surface of the drill bit 2, improving the applicability of the spray head 5 to different deep hole processing, solving the problem that a large amount of cutting fluid cannot be sprayed into the deep hole due to the fixed angle of the spray head 5, and improving the overall lubrication effect in the hole.
