Description

Technical Field

[0001] The invention belongs to the technical field of hardware processing, and in particular relates to a hardware inner wall chamfering machine. Background Art

[0002] Hardware refers to various parts and accessories made of metal materials, which are widely used in machinery, construction, automobiles, electronics, home appliances, furniture, transportation, tools and other industries. As the basic industrial accessories, the manufacturing technology and quality of hardware directly affect the performance and life of the whole product. With the development of industrialization, the manufacturing of hardware has gradually shifted from manual production to mechanization, automation and precision processing. In the production process of hardware, especially after cutting, stamping, milling and other processes, burrs or sharp edges often appear on the edges of parts. These burrs not only affect the appearance, but also may cause problems in the assembly process. Therefore, it is necessary to chamfer the inner wall of the hardware. You need to use a chamfering machine to improve the shape of the inner wall of the hardware, make its edge smoother, and facilitate subsequent processing and assembly. Effectively remove burrs and sharp edges, ensure the smooth edge of the hardware, and reduce the defective rate in production. Especially for hardware that needs to be assembled with other parts, chamfering can ensure better fit between parts and avoid fitting problems caused by uneven or sharp edges during assembly.

[0003] When existing chamfering machines chamfer hardware, they can only chamfer the inner holes of hardware with specific shapes and sizes. For the inner holes of hardware with irregular shapes and sizes, manual operation is often required to achieve chamfering, which limits its application on parts with complex shapes and requires more manual intervention in the production process. In addition, manual operation not only increases labor intensity, but may also introduce human errors, reduce processing accuracy and production efficiency, and affect the overall production process. In order to cope with irregular-shaped inner holes, operators may need to spend more time and energy on adjustments or manual trimming, which directly affects processing efficiency. In mass production, this manual operation will become a bottleneck and it is difficult to meet the needs of efficient production. Summary of the invention

The first motor 1 5. The output ends of the second motor 16 and the third motor 17 are rotatably connected to the connecting frame 2, the through-end of the first motor 15 is fixedly connected to the rotating rod 18, the through-end of the second motor 16 is fixedly connected to the toothed column 24, the through-end of the third motor 17 is fixedly connected to the through-end of a synchronous wheel connecting shaft in the second synchronous belt assembly 28, the toothed column 24 is meshed with the rack 23, and both ends of the toothed column 24 are rotatably connected to the connecting frame 2, one end of the rack 23 is rotatably connected to the first connecting member 25, and the other end of the first connecting member 25 is rotatably connected to the second connecting member 27, so that the machine can cut in different directions at the same time, reducing waiting time and idling time of the machine.

[0040] The coordination of multiple motors enables the equipment to quickly complete chamfering processing at different angles and directions. The other end of the second connecting member 27 is rotatably connected to the connecting frame 2. The second connecting member 27 and the top of the first connecting member 25 are rotatably connected with the second synchronous belt assembly 28 and the first synchronous belt assembly 26. The two synchronous wheel connecting shafts in the first synchronous belt assembly 26 are rotatably connected to the first connecting member 25, and the through-ends of the two synchronous wheel connecting shafts in the first synchronous belt assembly 26 are in opposite directions. The through-end of a synchronous wheel connecting shaft in the second synchronous belt assembly 28 is fixedly connected to the through-end of a synchronous wheel connecting shaft in the first synchronous belt assembly 26.

The two synchronous wheel connecting shafts in the second synchronous belt assembly 28 are rotatably connected to the second connecting member 27, and the limit frame 22 limits the rack 23, so that the boring tool 40 can maintain stable cutting during the processing, avoiding surface roughness or defects caused by unstable motion trajectory or cutting force, and ensuring that the inner edge of the processed hardware is flat and smooth.

[0041] The working principle of this embodiment is as follows: the hardware is placed between two slides 12, and then the double threaded rod 14 is rotated by turning the handle 13, so that the two slides 12 move toward each other on the fixed platform 11, thereby clamping and fixing the hardware. Then the staff can operate the control panel 3 to operate the components in the chamfering machine, thereby performing the chamfering process.

[0042] The operation of the first motor 15 drives the rotating rod 18 to rotate. Under the joint action of the spiral groove 19 and the fixed rod 21 in the slider 20, the slider 20 moves back and forth along the linear direction of the rotating rod 18. When the limit frame 22 moves, the top rack 23 always maintains a meshing state with the tooth column 24, and the second connecting member 27 and the first connecting member 25 connected to one end of the rack 23 rotate relative to each other to adapt to the overall movement trajectory of the rack 23.

[0043] The second motor 16 drives the gear column 24 to rotate, driving the rack 23 to move along the linear direction of the limit frame 22, and the second connecting member 27 and the first connecting member 25 on one side rotate relative to each other. Through the above steps, the movement of the rack 23 in the longitudinal and transverse directions is achieved.

[0044] The operation of the third motor 17 drives the second synchronous belt assembly 28 to transmit, and then drives the first synchronous belt assembly 26 on the other side to transmit, so that the hydraulic rod 29 and its components at the bottom rotate at the same time, and when the rack 23 moves in the longitudinal and transverse directions, the first connecting member 25 and the second connecting member 27 are deflected to different degrees, and the synchronous belts in the second synchronous belt assembly 28 and the first synchronous belt assembly 26 can always remain taut, and will not cause transmission obstruction.

[0045] The operation of the hydraulic rod 29 causes the connecting block 31 to move back and forth in the fixed frame 30, and the first connecting plate 32 rotatably connected thereto generates relative rotation, which causes the third connecting plate 34 connected to the other end of the first connecting plate 32 to generate transmission, thereby causing the second connecting plate 33 to deflect with the connection with the fixed frame 30 as the origin, thereby causing the fourth connecting plate 35 and the fifth connecting plate 36 connected thereto to rotate, and at the same time causing the fifth connecting plate 36 to rotate with the connection with the sleeve plate 38 as the origin, thereby causing the sixth connecting plate 37 at the other end of the fifth connecting plate 36 to rotate with the connection with the fifth connecting plate 36 as the origin, causing the movable plate 39 to move back and forth on the sleeve plate 38, thereby realizing the up and down extension and retraction of the boring tool 40 and always keeping it in the same straight line with the fixed frame 30, and the boring tool 40 rotates under the drive of the first synchronous belt assembly 26.

[0046] Through the above steps, the inner holes of hardware of different shapes and sizes can be chamfered, and during the chamfering, the first servo motor 4 and the second servo motor 5 are operated, the first servo motor 4 drives the U-shaped frame 6 to rotate, under the action of the ring plate 7, the fixed platform 11 and the hardware on the top thereof rotate horizontally, and the second servo motor 5 drives the first U-shaped plate 9 to rotate, and at the same time, since the second U-shaped plate 10 is connected to the first U-shaped plate 9 in a cross shape, the second U-shaped plate 10 moves synchronously with the first U-shaped plate 9 (the second The U-shaped plate 10 can rotate relative to the first U-shaped plate 9 or the second U-shaped plate 10 and the first U-shaped plate 9 can move in a relatively static state), so that the ring plate 7 rotates relative to the U-shaped frame 6, so that the fixed platform 11 and the hardware on the top of it rotate in the vertical direction. With the cooperation of the first servo motor 4 and the second servo motor 5, the fixed platform 11 and the hardware on the top of it can be deflected at any angle, so that the chamfering machine can chamfer the inner holes of hardware of different shapes and sizes to meet the needs of processing special-shaped holes.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
