Description

Technical Field

[0001] This utility model belongs to the field of machining technology, and specifically relates to a drilling device for diesel generator couplings. Background Technology

[0002] As a core component connecting the generator and the diesel engine output shaft, the diesel generator coupling requires the machining of multiple evenly distributed mounting holes. The accuracy of these holes directly affects the coaxiality and transmission stability of the assembled coupling. However, some existing coupling drilling devices have the following drawbacks in practical applications: First, they have poor adaptability. Special fixtures need to be changed for couplings of different diameters, making disassembly and assembly cumbersome. The drill bit position also needs to be adjusted for different hole spacings, which is time-consuming. Drilling is done in single-hole operation, resulting in low drilling efficiency. Second, chip disposal is inconvenient. Metal chips generated during drilling tend to accumulate in the processing area, requiring regular manual cleaning and increasing labor intensity. To address the aforementioned issues, there is an urgent need to design a diesel generator coupling drilling device that is highly adaptable, easy to clean up debris, and has high processing efficiency, in order to meet the needs of industrialized mass production. Summary of the Invention

[0003] The present invention aims to solve the problems of "poor adaptability, low drilling efficiency, and inconvenient debris cleaning" in the prior art, and provides a diesel generator coupling drilling device with strong adaptability, easy debris cleaning, and high processing efficiency.

[0004] To achieve the above-mentioned technical objectives, the solution adopted by this utility model is as follows: A diesel generator coupling drilling device includes a vertically arranged lifting platform and a longitudinal rotating ring. The front side of the lifting platform is provided with a vertically arranged transverse adjustment rail and a transverse adjustment screw. The front sides of the transverse adjustment rail and the transverse adjustment screw are connected to two transversely symmetrically arranged movable drills. Each movable drill is connected to a drill bit one-to-one downwardly. The two drill bits rotate synchronously in opposite directions. The outer annular surface of the longitudinal rotating ring is connected with several turntables at equal intervals. Each turntable is connected to a multi-jaw chuck in a one-to-one manner. The multi-jaw chuck rotates 360° based on the central axis of the longitudinal rotating ring. A through-hole drill cuttings blowing channel is provided from the upper surface of the multi-jaw chuck to the inner annular surface of the longitudinal rotating ring. The inner circumference of the longitudinal rotating ring is provided with a downward-facing blowing air outlet.

[0005] Furthermore, the back of the movable drill rig is connected to a transverse adjustment rail via a slider and to a transverse adjustment screw via a nut. The transverse adjustment screw has two symmetrical threads on the left and right sides.

[0006] Furthermore, the movable drill platform is connected to a lower rotating shaft via a rotating bearing seat. The bottom end of the lower rotating shaft is connected to a drill bit via a drill bit clamp. The upper end of the lower rotating shaft is connected to an upper rotating shaft via a telescopic universal joint. A driven gear is coaxially fixed on the upper rotating shaft.

[0007] Furthermore, the upper rotating shaft is connected to the lifting platform through a rotating bearing seat, and a meshing main gear is provided between the two driven gears. The main gear is driven to rotate by the main drilling motor.

[0008] Furthermore, the turntable adjusts the lateral rotation angle of the corresponding multi-jaw chuck, and the longitudinal rotating ring synchronously adjusts the longitudinal rotation angle of all turntables.

[0009] Furthermore, the longitudinal rotating ring is arranged perpendicular to the rotation axis of the turntable, and the number of turntables is ≥2.

[0010] Furthermore, a lateral adjustment motor is connected to the side of the adjusting screw.

[0011] Furthermore, the two drill bits are arranged side by side in parallel, and they move closer or further apart synchronously to adjust the spacing.

[0012] Furthermore, the purge air outlet is connected to the blower via a corrugated pipe.

[0013] The main beneficial effects of adopting the above technical solution are as follows: 1. High adaptability: The multi-jaw chuck can adaptively clamp couplings of different diameters; the turntable and longitudinal swivel can flexibly adjust the workpiece angle; the transverse adjusting screw can quickly adjust the distance between two drill bits to adapt to different hole spacing requirements without frequent fixture changes.

[0014] 2. High processing efficiency: The dual drill bits rotate synchronously in opposite directions and the spacing can be adjusted synchronously, enabling "simultaneous processing of two holes"; combined with the longitudinal rotating ring driving multiple sets of multi-jaw chucks to rotate and switch workstations, "batch continuous drilling" is achieved, greatly improving processing efficiency.

[0015] 3. Convenient debris removal: The blower delivers air to the blower nozzle through a corrugated pipe. The airflow passes through the drill chip blowing channel and can quickly blow the drilling debris downwards for collection, reducing the amount of manual cleaning work. Attached Figure Description

In the description of the present utility model, it should be understood that the terms "upper", "lower", "inner", "outer", "horizontal", "vertical", etc. used to indicate the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the technical solutions of the present utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present utility model.

[0018] Please refer to the following: Figures 1-5 The diesel generator coupling drilling device mainly consists of two parts: a lifting platform and drilling assembly, and a longitudinal rotating ring and clamping assembly. The specific structure is as follows: The lifting platform and drilling assembly: The front side of the lifting platform 1 is provided with horizontal adjustment rails 3 and horizontal adjustment screws 4 distributed vertically. The front sides of the two are connected to two horizontally symmetrical movable drilling platforms 5. The back of the movable drilling platform 5 is connected to the horizontal adjustment rails 3 through a slider and to the horizontal adjustment screws 4 through a nut (the horizontal adjustment screws 4 are machined with left and right symmetrical threads). The horizontal adjustment screws 4 are driven by the horizontal adjustment motor 18, so that the two movable drilling platforms 5 can "synchronously approach / move away". Each movable drill rig 5 is connected to the drill bit 6 via a lower rotating shaft 11 and a drill bit clamp 12. The upper end of the lower rotating shaft 11 is connected to the upper rotating shaft 14 via a telescopic universal joint 13. A driven gear 15 is coaxially fixed on the upper rotating shaft 14. A main gear 16 is provided between the two driven gears 15. The main gear 16 is driven to rotate by the main drilling motor 17, which ultimately enables the two drill bits 6 to achieve "synchronous reverse rotation" and synchronous drilling.

[0019] The longitudinal rotating ring and clamping assembly includes: ≥2 turntables 7 are evenly spaced on the outer annular surface of the longitudinal rotating ring 2, and a multi-jaw chuck 8 is connected to each turntable 7 in a one-to-one manner; the turntable 7 can adjust the lateral rotation angle of the corresponding multi-jaw chuck 8, and the longitudinal rotating ring 2 can synchronously adjust the longitudinal rotation angle of all turntables 7 (and the rotation axis of the longitudinal rotating ring 2 and the turntable 7 are perpendicular to each other); the multi-jaw chuck 8 can achieve 360° rotation based on the central axis of the longitudinal rotating ring 2, and a through-hole drill cuttings blowing channel 9 is provided from the upper surface of the multi-jaw chuck 8 to the inner annular surface of the longitudinal rotating ring 2; the inner circumference of the longitudinal rotating ring 2 is provided with a downward-facing blowing air port 10, and the blowing air port 10 is connected to a blower through a corrugated pipe 19.

[0020] The working process of the diesel generator coupling drilling device provided by this utility model is as follows: Workpiece clamping and angle adjustment: The diesel generator coupling to be drilled is clamped on the multi-jaw chuck 8, which can adaptively clamp according to the diameter of the coupling. If the longitudinal angle of the coupling needs to be adjusted, all the turntables 7 are rotated synchronously by the longitudinal swivel ring 2, so that the corresponding coupling moves to the uppermost processing area and the hole to be processed is aligned with the drill bit 6. If the lateral angle of the coupling needs to be adjusted, the multi-jaw chuck 8 is rotated by the turntable 7.

[0021] Drill bit spacing adjustment: Start the transverse adjustment motor 18 to drive the transverse adjustment screw 4 to rotate; since the screw has "left and right symmetrical threads", the two movable drill rigs 5 will move "closer or further away" synchronously along the transverse adjustment rail 3, thereby adjusting the spacing between the two drill bits 6 to adapt to the different machining hole spacing requirements of the coupling.

[0022] Drilling: Start the main drilling motor 17 to drive the main gear 16 to rotate; the main gear 16 meshes with the two driven gears 15, causing the two upper rotating shafts 14 to rotate synchronously in opposite directions; the upper rotating shafts 14 drive the lower rotating shaft 11 to rotate through the telescopic universal joint 13, ultimately causing the two drill bits 6 to rotate synchronously in opposite directions; control the lifting platform 1 to move downward, and the drill bits 6 contact the coupling to perform drilling.

[0023] Debris removal: After drilling is completed, the longitudinal rotating ring 2 rotates and locks in place. The multi-jaw chuck 8 descends to the lower cleaning position. The blower continuously delivers air to the cleaning port 10 through the corrugated pipe 19. After the airflow is blown out through the cleaning port 10 inside the longitudinal rotating ring 2, it enters the drill chip cleaning channel 9 on the multi-jaw chuck 8, which quickly blows the drill chips downward and discharges them. A collection container is set below.

[0024] Multi-station machining: After a set of holes is machined on a coupling on a multi-jaw chuck 8, the longitudinal rotating ring 2 rotates to move the next multi-jaw chuck 8 with the coupling clamped to the "drilling station" to achieve continuous batch machining.

[0025] Through the above structure and process, this device can efficiently and conveniently complete the drilling operation of diesel generator couplings of different specifications, and can automatically clean and collect debris to meet the needs of industrial mass production.

[0026] It should be noted that in the present invention, the "connection" not specifically defined can be a fixed connection, a detachable connection, or an integral connection; those skilled in the art can make corresponding adjustments and changes according to the specific application.

[0027] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications and substitutions can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
