Description

Technical Field

[0001] This utility model belongs to the field of drill bit processing technology, and specifically relates to a drill bit processing cooling water spray mechanism. Background Technology

[0002] Cooling is crucial during drill bit machining. Effective cooling not only extends the lifespan of the drill bit but also ensures machining accuracy and product quality.

[0003] A search revealed a patent in the relevant field with publication number CN221210825U, entitled "A Cooling Water Spray Mechanism for Drill Bit Processing." This spray mechanism allows for adjustment of the water spray position, thus meeting the needs of different processing positions to some extent. However, its placement above the processing position has a significant drawback.

[0004] In actual drill bit machining, the machining direction is complex and varied, and different machining processes and operational requirements necessitate cooling water spraying from different angles. However, existing top-mounted spray mechanisms, due to their fixed position, cannot flexibly adjust the spray angle according to the machining direction. This results in cooling water failing to accurately reach the areas requiring cooling in certain machining situations, significantly reducing the cooling effect and impacting drill bit machining quality and production efficiency. Therefore, this paper provides an alternative drill bit machining cooling water spray mechanism to solve the aforementioned technical problems. Utility Model Content

[0005] To address the problem of existing drill bit cooling water spray mechanisms that are inconvenient for flexibly adjusting the spray angle according to the actual operating direction, this utility model provides a drill bit cooling water spray mechanism. The carrier can be slidably adjusted left and right on the vertical plate to the corresponding hole position and fixed by a positioning mechanism. After loosening the tightening bolt A, the spray angle of the L-shaped pipe and spray nozzles can be precisely controlled by rotating the adjusting ring, thereby meeting the cooling requirements of the drill bit at different processing angles. It is easy to operate, offers flexible spray angle adjustment, and has strong adaptability, effectively overcoming the shortcomings of traditional drill bit cooling water spray mechanisms in terms of poor spray angle adjustment and difficulty in flexibly adjusting according to the actual operating direction. This greatly improves the cooling efficiency and processing accuracy during drill bit processing and is suitable for various complex processing scenarios. The specific technical solution is as follows:

[0006] A cooling water spraying mechanism for drill bit processing, including a water collecting pool. A vertical plate is fixedly installed on the upper surface of the water collecting pool. A plurality of fitting holes are penetratingly opened on the front surface of the vertical plate. A carrier is slidably installed on the upper surface of the vertical plate. The carrier is J-shaped, and a "soil"-shaped cylinder is fixedly installed through the carrier. A positioning mechanism is rotatably installed at one end of the "soil"-shaped cylinder close to the carrier. A movable ring is rotatably installed at one end of the "soil"-shaped cylinder away from the carrier. A pipe rack is fixedly installed on the outer surface of the movable ring. An L-shaped pipe is fixedly installed in the pipe rack. The water inlet end of the L-shaped pipe is connected with a telescopic water supply pipe. The water drainage end of the L-shaped pipe is fixedly installed with a spray nozzle. The water inlet end of the telescopic water supply pipe is connected with an external high-pressure water supply device.

[0007] In the above technical solution, a tightening bolt A is penetratingly screwed and installed on the outer surface of the movable ring. The lower end of the tightening bolt A is in contact with the outer surface of the "soil"-shaped cylinder. A tightening bolt B is penetratingly screwed and installed on the outer surface of the pipe rack. The lower end of the tightening bolt B is in contact with the outer surface of the L-shaped pipe;

[0008] In the above technical solution, the positioning mechanism includes a tightening ring. The tightening ring is slidably installed at the right end of the "soil"-shaped cylinder, and a spring is fixedly installed between the tightening ring and the inner surface of the carrier;

[0009] In the above technical solution, two operating rods are symmetrically fixedly installed on the outer surface of the tightening ring. The operating rods are Z-shaped;

[0010] In the above technical solution, the telescopic water supply pipe is fixedly installed on the upper surface of the carrier;

[0011] In the above technical solution, a fixing plate is fixedly installed on the rear surface of the water collecting pool. A hydraulic telescopic rod is fixedly installed on the upper surface of the fixing plate. A support plate is fixedly installed at the top end of the hydraulic telescopic rod. A plurality of arc-shaped support grooves are opened on the upper surface of the support plate. The arc-shaped support grooves and the corresponding fitting holes are on the same vertical line.

[0012] In the above technical solution, two guiding rods are symmetrically fixedly installed on the lower surface of the support plate. The guiding rods penetrate through the fixing plate.

[0013] The cooling water spraying mechanism for drill bit processing of the present utility model, compared with the prior art, has the beneficial effects as follows:

[0014] I. This utility model allows the carrier to slide left and right on the upright plate to the corresponding hole position and be fixed by the positioning mechanism. After loosening the tightening bolt A, the spray angle of the L-shaped tube and the spray nozzle can be precisely controlled by rotating the adjusting ring, thereby meeting the cooling needs of the drill bit at different processing angles. It is easy to operate, flexible in spray angle adjustment, and highly adaptable. It effectively overcomes the shortcomings of traditional drill bit processing cooling water spray mechanisms in terms of poor flexibility in spray angle adjustment and difficulty in flexibly adjusting according to the actual operation direction. It greatly improves the cooling efficiency and processing accuracy of the drill bit during processing and is suitable for a variety of complex processing scenarios.

[0015] Second, after the drill bit is placed through the adapter hole and the "E"-shaped cylinder, the present invention can use the hydraulic telescopic rod to extend and drive the support plate to move upward. The support plate and the adapter hole work together to effectively clamp the drill bit from both above and below, and fix the drill bit firmly inside the adapter hole. This enhances the stability of the drill bit during the processing, ensures that the drill bit can maintain a precise position under various processing forces, reduces vibration and offset, thereby significantly improving processing accuracy and ensuring processing quality.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] In this embodiment, front, back, left, right, top, and bottom are... Figure 1 Describe the reference plane. See [link / reference] Figures 1-4 This utility model provides a technical solution:

[0023] A cooling water spraying mechanism for drill bit processing includes a water collection tank 1. A vertical plate 2 is fixedly installed on the upper surface of the water collection tank 1. Multiple adapter holes 21 are formed through the front surface of the vertical plate 2 (the diameter of the adapter holes 21 is the same as the outer diameter of the drill bit to be processed). A carrier frame 3 is slidably installed on the upper surface of the vertical plate 2. The carrier frame 3 is J-shaped, and a U-shaped cylinder 31 is fixedly installed through the carrier frame 3. A positioning mechanism 4 is rotatably installed at the end of the U-shaped cylinder 31 near the carrier frame 3, and a movable ring 5 is rotatably installed at the end of the U-shaped cylinder 31 away from the carrier frame 3. A pipe rack 6 is fixedly installed on the outer surface of the pipe rack 6. An L-shaped pipe 7 is fixedly installed inside the pipe rack 6. The inlet end of the L-shaped pipe 7 is connected to a telescopic water supply pipe 32. A spray nozzle 71 is fixedly installed on the outlet end of the L-shaped pipe 7. The inlet end of the telescopic water supply pipe 32 is connected to an external high-pressure water supply device. A tightening bolt A51 is threaded through the outer surface of the movable ring 5. The lower end of the tightening bolt A51 is in contact with the outer surface of the "E" shaped cylinder 31. A tightening bolt B61 is threaded through the outer surface of the pipe rack 6. The lower end of the tightening bolt B61 is in contact with the outer surface of the L-shaped pipe 7.

[0024] Combination Figure 1 , Figure 2 and Figure 3 As shown, a groove 22 is provided on the rear surface of the upright plate 2. The rear end of the carrier frame 3 is slidably installed in the groove 22. Through the cooperation between the groove 22 and the rear end of the carrier frame 3, the carrier frame 3 can slide more stably on the upper surface of the upright plate 2.

[0025] In use, the carrier 3 is slid laterally along the upper surface of the upright plate 2 to adjust its position, so that the opening of the "E"-shaped cylinder 31 is connected to the corresponding adapter hole 21. Then, the positioning mechanism 4 is used to clamp and fix the carrier 3 onto the upright plate 2. Subsequently, combined with... Figure 1 and Figure 3As shown, after loosening the locking bolt A51 to separate its bottom from the outer surface of the "earth" shaped cylinder 31, rotate the adjusting ring 5 to drive the L-shaped pipe 7 and the spray nozzle 71 to rotate around the center point of the "earth" shaped cylinder 31 to adjust the spray angle. During the adjustment process, the telescopic water supply pipe 32 freely extends and retracts to adapt to the adjustment of the L-shaped pipe 7. After adjusting to the appropriate position, tighten the locking bolt A51 to fix the position of the adjusting ring 5, thereby ensuring the stability of the L-shaped pipe 7 and the spray nozzle 71. Then, pass the drill bit to be processed through the adapter hole 21 and the "earth" shaped cylinder 31. After being limited, processing can begin. On the left side, coolant is supplied to the L-shaped pipe 7 using an external high-pressure water supply device. The coolant is sprayed from the spray nozzle 71 onto the drill bit processing position for cooling. Compared with existing technologies, this spray mechanism can precisely control the spray angle of the L-shaped pipe 7 and the spray nozzle 71, thereby meeting the cooling requirements of the drill bit at different processing angles. It is easy to operate, has flexible spray angle adjustment, and strong adaptability, effectively overcoming the shortcomings of traditional drill bit processing cooling water spray mechanisms in terms of poor flexibility in spray angle adjustment and difficulty in flexibly adjusting according to the actual operating direction.

[0026] Combination Figure 3 and Figure 4 As shown, the positioning mechanism 4 includes a clamping ring 41, which is slidably installed on the right end of the "earth" shaped cylinder 31. A spring 42 is fixedly installed between the clamping ring 41 and the inner surface of the carrier 3. The clamping ring 41 can remember the extension pressure of the spring 42, so that the clamping ring 41 is pressed against the front surface of the upright plate 2, thereby clamping and fixing the carrier 3 on the upright plate 2.

[0027] In addition, at the position of the sliding adjustment frame 3, in order to make it easier and more convenient for the clamping ring 41 to move away from the upright plate 2, two operating rods 43 are symmetrically fixed on the outer surface of the clamping ring 41. The operating rods 43 are Z-shaped and can be used to drive the clamping ring 41 to move, thereby making its adjustment operation easier and more convenient.

[0028] Specifically, the telescopic water supply pipe 32 is fixedly installed on the upper surface of the carrier 3;

[0029] To facilitate limiting the position of the drill bit to be processed, such as Figure 2As shown, a fixing plate 8 is fixedly installed on the rear surface of the water collection tank 1. A hydraulic telescopic rod 81 is fixedly installed on the upper surface of the fixing plate 8. A support plate 82 is fixedly installed at the top of the hydraulic telescopic rod 81. Multiple arc-shaped grooves 821 are formed on the upper surface of the support plate 82. The arc-shaped grooves 821 and the corresponding adapter holes 21 are located on the same vertical line. When the hydraulic telescopic rod 81 extends, it can drive the support plate 82 to move upward. As the support plate 82 moves upward, the support plate 82 and the adapter holes 21 work together to effectively clamp the drill bit from both the top and bottom directions, and firmly fix the drill bit inside the adapter holes 21, thereby enhancing the stability of the drill bit during processing.

[0030] Finally, to ensure the stability of the pallet 82 during lifting, two directional rods are symmetrically fixedly installed on the lower surface of the pallet 82, and both directional rods penetrate the fixed plate 8.
