Description

Technical Field

[0001] This utility model relates to the field of stator flange processing, specifically a stator flange drilling and chip removal mechanism. Background Technology

[0002] A chip removal mechanism is a device for cleaning waste chips and residue from objects. A search revealed a utility model patent with patent application number CN201920348508.9, which discloses an automatic rotating device for cleaning iron filings from threaded holes. This device includes a turntable with a driven gear at its upper end. The driven gear has a threaded hole. The turntable is fixed to a worktable and its lower end is connected to a ratchet mechanism. A flexible hose is mounted on the worktable, and a nozzle is installed on the flexible hose above the threaded hole. This utility model achieves the rotation of the turntable, driving the driven gear and threaded hole to rotate. When the threaded hole rotates to the underside of the nozzle on the flexible hose, compressed air from the nozzle blows out the residual tapping iron filings inside the threaded hole. This results in good chip removal efficiency and avoids damage. It solves the problem of residual iron filings in the threaded hole after tapping, where manual tapping is labor-intensive, inefficient, and produces poor cleaning results, and is also prone to damage.

[0003] As mentioned above, current methods for cleaning debris from drill holes primarily rely on airflow. However, this method is not very effective. During drilling, coolant is sprayed towards the drilling site to prevent the drill bit and other workpieces from overheating. This causes debris to adhere to the hole wall due to the coolant's adsorption effect. Furthermore, metallic debris is easily attracted to the hole wall during drilling, making it difficult to remove the debris quickly. Moreover, existing debris removal mechanisms are mostly independent, requiring cleaning of the pores after drilling is complete, which delays the overall processing progress of the stator flange. Therefore, improvements are needed. Utility Model Content

[0004] The purpose of this utility model is to provide a stator flange drilling chip removal mechanism, which solves the problem that existing chip removal mechanisms are difficult to clean due to the adsorption of coolant and the adsorption force of the waste chips themselves. At the same time, it also solves the problem that independently set chip removal mechanisms delay the stator flange processing progress.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a stator flange drilling and chip removal mechanism, including a mounting frame, which is an "L"-shaped bracket. At least one mounting hole is provided on each of the top two sides of the mounting frame. A strip plate is rotatably mounted on the bottom of the mounting frame via a rotating shaft. A locking bolt is mounted on the rotating shaft. A strip groove is provided on the strip plate. A ring is fitted onto the strip plate. A locking bolt is threaded to the end of the ring, and the end of the locking bolt abuts against the strip plate. A rotating tube is rotatably mounted in the middle of the ring, and the rotating tube passes through the ring. A driving mechanism is provided at the top of the rotating tube. An air pump is rotatably mounted at the top of the rotating tube, and the air pump is fixedly connected to the ring via a support frame. Multiple air holes are provided on the bottom side of the rotating tube, and a brush is provided on the bottom outer wall of the rotating tube.

[0006] Preferably, the mounting hole is a strip-shaped slot that extends through the mounting frame. The strip-shaped mounting hole allows for adjustment of the mounting frame's position on the drilling equipment. This enables the mounting frame to be adjusted according to factors such as drill bit length, allowing for easy installation of the mounting frame by changing the distance between its bottom and the drill bit, thus improving the adaptability of the chip removal mechanism during installation.

[0007] Preferably, the bottom of the rotating tube is sealed, and the rotating tube is connected to the air pump. The sealing of the bottom of the rotating tube ensures that all gas entering the rotating tube flows out through the air vent.

[0008] Preferably, the driving mechanism includes a first gear, which is fixedly mounted on the top of the rotating tube. A second gear meshes with the side of the first gear, and a drive motor is mounted on the second gear. The drive motor is fixedly connected to the ring sleeve via a support frame. The operation of the drive motor provides power for the rotation of the rotating tube.

[0009] Preferably, the brush is fixedly mounted on a connecting plate, and there are multiple connecting plates arranged at intervals along the outer wall of the rotating tube. The air hole is located between two adjacent connecting plates. Both the upper and lower ends of the connecting plate are fixedly mounted on a sleeve, which is fixed to the rotating tube by bolts. The detachable installation of the sleeve on the rotating tube facilitates the disassembly and replacement of the brush.

[0010] Preferably, both the screw of locking bolt one and the screw of locking bolt two are fitted with elastic washers. The washers improve the locking effect of locking bolt one and locking bolt two.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model allows for adjustable spacing between the brush and the drill bit by sliding the ring on the strip plate and rotating the strip plate with the mounting bracket. This enables the chip removal mechanism to be directly fixed on the drilling device. The position of the rotating tube can be adjusted according to the spacing between two adjacent holes of the stator flange, allowing the rotating tube to extend into the previously drilled hole for chip removal as the drill bit drills. This achieves simultaneous drilling and chip removal, improving the drilling efficiency of the stator flange.

[0013] 2. This utility model uses the rotation of the brush and the blowing of gas at the air hole to clean the waste debris attached to the stator flange hole and blow the waste debris out of the hole, effectively preventing the waste debris from adhering to the hole wall and ensuring the cleaning efficiency.

Detailed Implementation

[0019] 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.

[0020] Please see Figure 1 , Figure 2 , Figure 3A stator flange drilling chip removal mechanism includes a mounting frame 1, which is an "L"-shaped bracket. At least one mounting hole 2 is provided on both sides of the top of the mounting frame 1. The mounting hole 2 is a strip-shaped slot and penetrates through the mounting frame 1. Through the strip-shaped mounting hole 2, the position of the mounting frame 1 on the drilling equipment is adjustable. The distance between the bottom of the mounting frame 1 and the drill bit can be adjusted according to the length of the drill bit and other conditions, and the mounting frame 1 can be installed, thereby improving the adaptability of the chip removal mechanism during installation.

[0021] Please see Figure 1 , Figure 3 , Figure 4 A strip plate 3 is rotatably mounted on the bottom of the mounting bracket 1 via a rotating shaft 4. A locking bolt 5 is mounted on the rotating shaft 4. A strip groove 6 is formed on the strip plate 3. A ring sleeve 7 is fitted on the strip plate 3. A locking bolt 8 is threaded to the end of the ring sleeve 7. The end of the locking bolt 8 abuts against the strip plate 3. Elastic washers are fitted on the screws of both the locking bolt 5 and the locking bolt 8 to improve the locking effect of the locking bolts 5 and 8. A rotating tube 9 is rotatably mounted in the middle of the ring sleeve 7 and passes through the ring sleeve 7. A brush 19 is provided on the bottom outer wall of the rotating tube 9 and is fixedly mounted on the connecting plate 18. Multiple plates 8 are arranged at intervals along the outer wall of the rotating tube 9. The upper and lower ends of the connecting plate 18 are fixedly installed on the sleeve 20. The sleeve 20 is fixed to the rotating tube 9 by bolts. The detachable installation of the sleeve 20 on the rotating tube 9 facilitates the disassembly and replacement of the brush 19. A drive mechanism 16 is provided at the top of the rotating tube 9. The drive mechanism 16 includes a gear 12, which is fixedly installed on the top of the rotating tube 9. A gear 13 meshes with the side of the gear 12. A drive motor 15 is installed on the gear 13. The drive motor 15 is fixedly connected to the ring 7 through the support frame 14. The operation of the drive motor 15 provides power for the rotation of the rotating tube 9.

[0022] Please see Figure 1 , Figure 2 , Figure 3 An air pump 10 is rotatably mounted on the top of the rotating tube 9, and the air pump 10 is fixedly connected to the ring sleeve 7 through a support frame 11. Multiple air holes 17 are opened on the bottom side of the rotating tube 9. The air holes 17 are located between two adjacent connecting plates 18. The bottom of the rotating tube 9 is a sealed structure. The rotating tube 9 is connected to the air pump 10. Through the bottom sealing of the rotating tube 9, it is ensured that the gas entering the rotating tube 9 flows out from the air holes 17.

[0023] The specific implementation process of this utility model is as follows: It should be noted that the stator flange is placed on a rotatable turntable during drilling. As the stator flange rotates, the continuously falling drill bit completes the drilling operation. In use, the mounting bracket 1 is placed above the drill bit of the drilling device, and the bolt is passed through the mounting hole 2 to fix the mounting bracket 1 to the drilling device. Then, the strip plate 3 is rotated, and the ring 7 is pulled to slide on the strip plate 3, thereby adjusting the position between the rotating tube 9 and the drill bit to correspond with the position between the two adjacent holes of the stator flange, that is, at the drill bit When drilling a hole in the stator flange, the rotating tube 9 can be inserted into an adjacent hole to remove debris. In actual use, when drilling the first hole in the stator flange, the rotating tube 9 can be rotated to a position away from the stator flange to prevent the rotating tube 9 from obstructing the fall of the drill bit. As the rotating tube 9 falls into the drilled hole, the rotating tube 9 will drive the brush 19 to rotate in the hole, thereby cleaning the debris attached to the hole wall. Under the action of the air vent 17 continuously blowing air outward, the debris is blown out of the hole, thus completing the cleaning of debris in the hole.
