Description

Technical Field

[0001] This utility model relates to the field of machining fixture technology, and more specifically, to a drilling fixture for the end face of an axle. Background Technology

[0002] A fixture is an auxiliary device used to fix, position, or clamp a workpiece, ensuring its stability during machining, assembly, or inspection. Its structure typically includes a clamping mechanism, a base, and adjustment components. Precise control is achieved through manual, pneumatic, or hydraulic drives. As a key link in the process chain, fixtures reduce human error through standardized operation, ensuring machining accuracy and product quality. They are an indispensable cornerstone of industrial automation and precision manufacturing.

[0003] A search revealed that a drilling fixture for axle end faces, with publication number CN205817364U, is described in the background section. Existing axle end face drilling fixtures mainly suffer from problems such as difficulty in fixing, cumbersome operation, easy damage to the axle, and insufficient fixation. The aforementioned problems are solved by setting a base, a fixing frame, a movable pressure block, a fixed pressure block, and a vertical support plate.

[0004] However, in the above-mentioned technology, if both ends of the axle need to be drilled, the operator needs to re-clamp the axle after drilling one end to process the other end face. This causes unnecessary trouble for the operator and slows down the speed and efficiency of axle processing. Therefore, it needs to be improved. Utility Model Content

The other end of the bolt passes through the second U-shaped frame and extends into the interior of the slot. The outer surface of the bolt and the inner surface of the slot are threaded together.

[0010] As a preferred technical solution of this utility model, a drive motor is fixedly installed on the right side of the lower surface of the second plate, and a round shaft is fixedly sleeved on the other end of the output shaft of the drive motor. A gear located behind the toothed plate is fixedly sleeved on the outer surface of the round shaft, and the outer surface of the gear and the outer surface of the toothed plate are meshed and connected.

The following description is provided to enable any person skilled in the art to implement and use the present invention. Details are set forth in the following description for purposes of explanation. It should be understood that those skilled in the art will recognize that the present invention can be implemented without using these specific details. In other instances, well-known structures and processes will not be described in detail to avoid obscuring the description of the present invention with unnecessary detail. Therefore, the present invention is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0027] like Figures 1 to 8As shown, this utility model provides a drilling fixture for axle end faces, including a bottom mounting plate 1. A first plate 2 is fixedly connected to the upper surface of the bottom mounting plate 1. A rotating column 3 is movably sleeved on the inner surface of the first plate 2. A limit ring 10 is fixedly sleeved on the bottom end of the outer surface of the rotating column 3. The outer surface of the limit ring 10 is movably connected to the inner surface of the first plate 2. A second plate 4 is fixedly connected to the top end of the rotating column 3. A sliding groove 5 is formed on the outer surface of the rotating column 3. A pneumatic cylinder 6 located on the left side of the rotating column 3 is fixedly installed on the lower surface of the first plate 2. The top end of the pneumatic cylinder 6 penetrates the first plate 2 and extends above the first plate 2, and is fixedly connected to a connecting block 7. A driving rod 8 is fixedly connected to the right surface of the connecting block 7. The outer surface of the driving rod 8 is movably connected to the inner surface of the slide groove 5. A first limiting rod 9 located below the second plate 4 is fixedly connected to the upper surface of the first plate 2. The top end of the first limiting rod 9 passes through the connecting block 7 and extends above the connecting block 7. The outer surface of the first limiting rod 9 is movably sleeved with the inner surface of the connecting block 7. When the operator starts the pneumatic cylinder 6, the connecting block 7 will move upward along the outer surface of the first limiting rod 9. The movement of the driving rod 8 will cause the rotating column 3 and the second plate 4 to start rotating, thereby causing the axle fixed above the second plate 4 to start rotating.

[0028] Among them, a first limiting plate 23 is fixedly connected to the left side of the upper surface of the first plate 2, and a second limiting plate 24 is fixedly connected to the right side of the upper surface of the bottom mounting plate 1. A cylinder 22 is movably connected to the rear surface of the second limiting plate 24, and the top of the cylinder 22 is fixedly connected to the lower surface of the second plate 4. The design of the cylinder 22 and the first limiting plate 23 makes the second plate 4 rotate only half a turn. When the cylinder 22 contacts the first limiting plate 23, the other unprocessed end face of the axle will be facing the drilling device.

[0029] Among them, a trapezoidal strip 11 is fixedly connected to the middle of the upper surface of the second plate 4, and a sliding plate 12 is movably connected to the outer surface of the trapezoidal strip 11. The lower surface of the sliding plate 12 is movably connected to the upper surface of the second plate 4. A toothed plate 13 is fixedly connected to the upper surface of the sliding plate 12. Positioning baffles 18 are movably connected to the outer surfaces of the front and rear sides of the sliding plate 12. The positioning baffles 18 are fixedly connected to the left and right ends of the upper surface of the second plate 4. This allows the sliding plate 12 and the toothed plate 13 to move on the upper surface of the second plate 4. The design of the positioning baffles 18 and the trapezoidal strip 11 restricts the overall movement direction of the sliding plate 12, so that the sliding plate 12 can only move left and right.

[0030] The sliding plate 12 has slots 14 on both the front and rear outer surfaces. A first U-shaped frame 15 is fixedly connected to the left end of the front and rear outer surfaces of the sliding plate 12. The left surface of the first U-shaped frame 15 is movably connected to the positioning baffle 18. A second U-shaped frame 16 located to the right of the first U-shaped frame 15 is movably connected to both the front and rear outer surfaces of the sliding plate 12. Bolts 17 are movably sleeved on both the front and rear outer surfaces of the second U-shaped frame 16. The other end of the bolt 17 passes through the second U-shaped frame 16 and extends into the slot 14. The outer surface of the bolt 17 and the inner surface of the slot 14 are threaded together. The second U-shaped frame 16 can move left and right along the outer surface of the sliding plate 12, thereby achieving the clamping function for axles of different lengths. The design of the slots 14 and bolts 17 serves to fix the second U-shaped frame 16 to the outer surface of the sliding plate 12.

[0031] Among them, a drive motor 19 is fixedly installed on the right side of the lower surface of the second plate 4. A round shaft 20 is fixedly sleeved on the other end of the output shaft of the drive motor 19. A gear 21 located behind the toothed plate 13 is fixedly sleeved on the outer surface of the round shaft 20. The outer surface of the gear 21 and the outer surface of the toothed plate 13 are meshed and connected. When the drive motor 19 starts to run, the round shaft 20 and the gear 21 will start to rotate. Since the gear 21 and the toothed plate 13 mesh with each other, the toothed plate 13 and the sliding plate 12 as a whole will start to move to the right under the drive of the gear 21.

[0032] Among them, fixed V-blocks 25 are fixedly connected to the lower side of the inner surface of the first U-shaped frame 15 and the second U-shaped frame 16. The lower surface of the fixed V-blocks 25 is movably connected to the upper surface of the toothed plate 13. Movable V-blocks 26 are movably connected to the upper side of the inner surface of the first U-shaped frame 15 and the second U-shaped frame 16. The movable V-blocks 26 can move downward along the inner surface of the first U-shaped frame 15 or the second U-shaped frame 16. When both the movable V-blocks 26 and the fixed V-blocks 25 contact the outer surface of the axle, the axle will be fixed by the fixed V-blocks 25 and the movable V-blocks 26, thereby ensuring the stability of the axle during the processing.

[0033] The upper surface of the movable V-block 26 is fixedly connected to a limiting sleeve 27. A circular block 28 is movably connected to the inner surface of the limiting sleeve 27. A threaded rod 29 located above the circular block 28 is movably sleeved on the inner surface of the limiting sleeve 27. The upper surface of the circular block 28 and the bottom end of the threaded rod 29 are fixedly connected. There are two threaded rods 29. The top ends of the two threaded rods 29 pass through the first U-shaped frame 15 and the second U-shaped frame 16 respectively and extend to the top of the first U-shaped frame 15 and the second U-shaped frame 16 and are fixedly connected to a handle 30. The outer surfaces of the two threaded rods 29 are threadedly sleeved with the inner surfaces of the first U-shaped frame 15 and the second U-shaped frame 16 respectively. When the operator rotates the handle 30, the threaded rod 29 and the circular block 28 will start to move up and down. The design of the limiting sleeve 27 makes the movable V-block 26 and the limiting sleeve 27 move up and down together with the circular block 28.

[0034] Working principle and usage process of this utility model:

[0035] First, the operator moves the second U-shaped bracket 16 so that the distance between the first U-shaped bracket 15 and the second U-shaped bracket 16 meets the clamping requirements of the axle. Then, the operator inserts bolt 17 into the inner surface of the second U-shaped bracket 16 and the slot 14 to fix the position of the second U-shaped bracket 16. Then, the operator places the axle above the two fixed V-blocks 25 and rotates the handle 30. As the handle 30 rotates, the threaded rod 29, the round block 28 and the movable V-block 26 move downward as a whole. Finally, the fixed V-block 25 and the movable V-block 26 clamp the axle, thereby fixing the axle between the fixed V-block 25 and the movable V-block 26.

[0036] Then, the operator uses a drilling device to drill a hole in one end face of the axle. Subsequently, the operator starts the pneumatic cylinder 6 and the drive motor 19. The operation of the pneumatic cylinder 6 causes the connecting block 7 and the driving rod 8 to move upward. The movement of the driving rod 8 drives the rotating column 3, causing the rotating column 3 and the second plate 4 to start rotating. Finally, when the cylinder 22 contacts the first limit plate 23, the unprocessed end face of the axle will be facing the drilling device. The operation of the drive motor 19 causes the round shaft 20 and the gear 21 to start rotating. The rotation of the gear 21 drives the toothed plate 13, causing the sliding plate 12, the toothed plate 13, the first U-shaped frame 15 and the second U-shaped frame 16 to move to the left. Finally, the second U-shaped frame 16 contacts the positioning baffle 18, allowing the operator to use the drilling device to drill a hole in the unprocessed end face of the axle.

[0037] Although preferred embodiments of the present invention have been described, those skilled in the art, upon learning the basic inventive concept, can make other changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the present invention.

[0038] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
