Description

Technical Field

[0001] This invention relates to the field of deburring technology, specifically a deburring device for the rectifier bridge housing of an automotive generator. Background Technology

[0002] After the rectifier bridge housing of an automotive generator is machined, burrs remain on its edges and inner and outer surfaces. These burrs not only affect the assembly accuracy of the rectifier bridge but also pose a risk of detachment during use, threatening the safe operation of the generator. Therefore, it is necessary to remove the burrs from the housing through deburring.

[0003] Most existing deburring processing equipment uses fixed-shaped grinding parts for grinding operations. For burrs of different positions and shapes on the housing, it is necessary to frequently change the corresponding shape of the grinding part. At the same time, it is also necessary to re-clamp and adjust the position of the housing multiple times in order to complete the deburring processing of all positions. The overall processing efficiency is low, and the adaptability to rectifier bridge housings of different specifications is poor, making it difficult to flexibly match the grinding requirements of different burr shapes and positions. Summary of the Invention

[0004] The purpose of this invention is to provide a deburring device for the rectifier bridge housing of an automotive generator, so as to solve the problems mentioned in the background art.

[0008] A movable support structure connected to the frame is disposed below the deformation and grinding section.

[0009] As a further improvement of the present invention: the moving part includes a first track fixedly connected to the frame, a drive motor fixedly connected to the first track, a screw fixedly connected to the output shaft of the drive motor, a second track threadedly connected to the screw, the second track being slidably connected to the first track, a first electric telescopic frame fixedly connected to the second track, a sliding block fixedly connected to the moving end of the first electric telescopic frame and slidably connected to the second track, and the sliding block being connected to the rotation drive part.

[0010] As a further improvement of the present invention: the rotation drive unit includes a synchronous frame fixedly connected to the sliding block, the synchronous frame is connected to the coaxial adjustment unit, the synchronous frame is rotatably connected to a limit rotating frame, the synchronous frame is fixedly connected to a second motor, the output shaft of the second motor is coaxially fixedly connected to a gear, the gear meshes with a gear ring, the gear ring is coaxially fixedly connected to the limit rotating frame, multiple sets of limit blocks are coaxially and equally angledly fixedly installed on the lower end surface of the limit rotating frame, the locking component is connected to the limit rotating frame, and each set of locking components is movably connected to a set of limit blocks.

[0011] As a further improvement of the present invention: the coaxial adjustment part includes two sets of second electric telescopic frames fixedly connected to the synchronous frame, and the moving ends of the two sets of second electric telescopic frames are fixedly connected to a set of annular groove frames. The inner side of the annular groove frame is provided with an annular groove that is slidably connected to the axial protruding end of the notch frame.

[0012] As a further improvement of the present invention: the locking component includes an upper bracket fixedly connected to the frame, the upper bracket being movably mounted on the limiting rotating frame, the upper bracket being movably connected to a card holder movably connected to the limiting block, and the card holder being connected to a screw threadedly connected to the upper bracket.

[0013] As a further improvement of the present invention: the displacement drive unit includes an electric telescopic rod fixedly connected to the synchronous frame, the moving end of the electric telescopic rod is fixedly connected to a rotating support seat, and the rotating support seat is rotatably connected to a pressure head. The electric telescopic rod, the rotating support seat, and the pressure head are all arranged above the longitudinal moving frame.

[0014] As a further improvement of the present invention: the movable bearing structure includes a movable platform slidably connected to the frame, a worktable is fixedly installed on the movable platform, the worktable is located below the arc surface grinding block, the frame is fixedly connected to a third electric telescopic frame, and the movable end of the third electric telescopic frame is fixedly connected to the movable platform.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] In use, the automotive alternator rectifier bridge housing to be deburred is placed on the movable support structure. The movable support structure, in conjunction with the moving part, adjusts the positions of the rotary drive unit, coaxial adjustment unit, deformable grinding unit, and displacement drive unit to adjust the relative position of the deformable grinding unit and the housing to be processed, ensuring the deformable grinding unit is aligned with the area on the housing to be deburred. When a flat surface needs to be ground separately, the displacement drive unit presses down on the longitudinal shift frame, compressing the spring and causing the flat grinding block to extend downwards. The rotary drive unit drives the locking assembly to rotate, which in turn drives the frame to rotate. The frame, through the connecting frame, drives the longitudinal shift frame to rotate, which in turn drives the flat grinding block to rotate, causing the curved surface... The grinding block performs deburring on the flat surface independently. When the curved surface of the housing needs to be ground and deburred, the coaxial adjustment unit works in conjunction, driving multiple notch frames to move simultaneously along the longitudinal groove. During the movement of the notch frames, the drive shaft pushes the connecting frame to rotate around the hinge position, causing the mating shell to swing the curved grinding block at an angle to match the curved contour of the housing. Then, the rotating drive unit drives all the deformable grinding parts to rotate, and the curved grinding block is in close contact with the curved surface to complete the grinding and deburring process. The entire deformable grinding part can be disassembled and assembled through the locking component, making it convenient to replace the grinding block of the corresponding size according to different specifications of the rectifier bridge housing to adapt to different processing requirements. This invention utilizes a combination of a movable bearing structure and a movable grinding structure. By employing a rotation drive unit in conjunction with a coaxial adjustment unit, multiple sets of deformable grinding units can be simultaneously driven to complete angle adjustments. This allows for simultaneous grinding of both the flat and curved surfaces of the rectifier bridge housing, eliminating the need for repeated replacement of grinding parts of different shapes and multiple clamping and adjustment of the housing position. This effectively improves the efficiency of deburring. Furthermore, the locking component enables quick disassembly and replacement of the deformable grinding units, facilitating the matching of grinding structures of corresponding sizes to rectifier bridge housings of different specifications. This enhances the adaptability and processing flexibility of the device. Attached Figure Description

[0028] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.

[0029] Example 1, see Figures 1-10 As shown, a deburring device for automotive alternator rectifier bridge housing includes a frame 1, a control panel 2 fixedly connected to the frame 1, and further includes:

[0030] A movable grinding structure 3 connected to the frame 1 includes a movable part 4 connected to the frame 1, a rotary drive part 5 connected to the movable part 4, a coaxial adjustment part 6 mounted on the rotary drive part 5, and multiple sets of deformable grinding parts 7 connected together by the rotary drive part 5 and the coaxial adjustment part 6. A displacement drive part 8 is connected to the rotary drive part 5 and is positioned above the deformable grinding parts 7. Each deformable grinding part 7 includes a locking assembly 9 connected to the rotary drive part 5, a frame 10 fixedly connected to the locking assembly 9, and a connecting frame 11 hinged to the frame 10. The connecting frame 11 is screwed... A bolted connection is provided with a docking shell 12. Two sets of springs 13 are fixedly installed inside the docking shell 12. The springs 13 are fixedly connected to a longitudinal moving frame 14 that is slidably connected to the docking shell 12. A flat grinding block 15 is fixedly installed at the lower end of the longitudinal moving frame 14. An arc-shaped grinding block 16 is fixedly connected to the docking shell 12. A drive shaft 17 is fixedly connected to the connecting frame 11. A notch frame 18 is slidably connected to the drive shaft 17. A one-way slot for driving the drive shaft 17 to move is provided on the notch frame 18. A longitudinal groove 19 is slidably connected to the notch frame 18 in the frame 10. The shaft-shaped protruding end of the notch frame 18 is slidably installed in the coaxial adjustment part 6.

[0031] A movable support structure 20 is connected to the frame 1 and is disposed below the deformation and grinding section 7.

[0032] In use, the rectifier bridge housing of the automotive alternator to be deburred is placed on the movable support structure 20. The movable support structure 20, in conjunction with the moving part 4, adjusts the positions of the rotation drive part 5, coaxial adjustment part 6, deformation grinding part 7, and displacement drive part 8 to adjust the relative position of the deformation grinding part 7 with the housing to be processed, so that the deformation grinding part 7 is aligned with the position of the housing to be deburred. When it is necessary to grind the surface separately, the displacement drive part 8 presses down the longitudinal shift frame 14, compressing the spring 13, so that the surface grinding block 15 extends downward. The rotation drive part 5 drives the locking assembly 9 to rotate, the locking assembly 9 drives the frame 10 to rotate, the frame 10 drives the longitudinal shift frame 14 to rotate through the connecting frame 11, and the longitudinal shift frame 14 drives the surface grinding block 15 to rotate, so that the arc surface grinding block 16 can be ground separately. After deburring the planar position, when it is necessary to grind and deburr the arc surface of the housing, the displacement drive unit 8 resets, the spring 13 pushes the longitudinal movement frame 14 to reset, and the coaxial adjustment unit 6 completes the linkage, driving multiple notch frames 18 to move simultaneously along the longitudinal groove 19. During the movement of the notch frame 18, the drive shaft 17 pushes the connecting frame 11 to rotate around the hinge position, so that the mating shell 12 drives the arc surface grinding block 16 to swing the angle to match the arc surface contour of the housing. Then, the rotation drive unit 5 drives all the deformable grinding parts 7 to rotate, and the arc surface grinding block 16 is in close contact with the arc surface to complete the grinding and deburring process. The entire deformable grinding part 7 can be disassembled and assembled by the locking component 9, which is convenient to replace the corresponding size grinding block according to different specifications of rectifier bridge housings to adapt to different processing requirements. This invention utilizes the interaction between the movable bearing structure 20 and the movable grinding structure 3, with the rotation drive unit 5 and the coaxial adjustment unit 6 working together to simultaneously drive multiple sets of deformable grinding units 7 to complete angle adjustments. This allows for simultaneous grinding of both the flat and curved surfaces of the rectifier bridge housing, eliminating the need for repeated replacement of grinding parts of different shapes and multiple clamping and adjustment of the housing position. This effectively improves the efficiency of deburring. At the same time, the locking component 9 enables quick disassembly and replacement of the deformable grinding units 7, facilitating the matching of grinding structures of corresponding sizes to rectifier bridge housings of different specifications, thus enhancing the adaptability and processing flexibility of the device.

[0033] In one embodiment, the moving part 4 includes a first track 21 fixedly connected to the frame 1. A drive motor 22 is fixedly connected to the first track 21. A screw 23 is fixedly connected to the output shaft of the drive motor 22. A second track 24 is threadedly connected to the screw 23 and slidably connected to the first track 21. A first electric telescopic frame 25 is fixedly connected to the second track 24. A sliding block 26, slidably connected to the second track 24, is fixedly connected to the moving end of the first electric telescopic frame 25. The sliding block 26 is connected to the rotation drive part 5. The drive motor 22 drives the second track 24 to move linearly along the first track 21 via the screw 23. The first electric telescopic frame 25 can drive the sliding block 26 to slide along the second track 24, thereby flexibly adjusting the planar position of the rotation drive part 5 and facilitating alignment with the workpiece processing position.

[0034] In one embodiment, the rotation drive unit 5 includes a synchronization frame 27 fixedly connected to the sliding block 26. The synchronization frame 27 is connected to the coaxial adjustment unit 6. The synchronization frame 27 is rotatably connected to a limiting rotation frame 28. The synchronization frame 27 is fixedly connected to a second motor 29. The output shaft of the second motor 29 is coaxially fixedly connected to a gear 30. The gear 30 meshes with a gear ring 31. The gear ring 31 is coaxially fixedly connected to the limiting rotation frame 28. Multiple sets of limiting blocks 32 are coaxially and equidistantly fixedly installed on the lower end surface of the limiting rotation frame 28. Locking components 9 are connected to the limiting rotation frame 28. Each set of locking components 9 is movably connected to a set of limiting blocks 32. The second motor 29 drives the gear ring 31 to rotate via the gear 30. The rotating gear ring 31 drives the limiting rotating frame 28 to rotate on the synchronous frame 27. The synchronous frame 27 provides rotational support and rotation limit for the limiting rotating frame 28. The limiting rotating frame 28 drives the locking component 9 to rotate via the limiting block 32, thereby driving all the deformable grinding parts 7 connected to the limiting rotating frame 28 to rotate, thus completing the grinding operation. The external meshing gear transmission method can ensure stable transmission and guarantee the stability of the rotational grinding process.

[0035] In one embodiment, the coaxial adjustment unit 6 includes two sets of second electric telescopic frames 33 fixedly connected to the synchronous frame 27. The moving ends of the two sets of second electric telescopic frames 33 are jointly fixedly connected to a set of annular groove frames 34. The inner side of the annular groove frame 34 is provided with an annular groove 35 that is slidably connected to the axial protruding end of the notch frame 18. The second electric telescopic frame 33 drives the annular groove frame 34 to move axially along the limiting rotation frame 28. The inner wall of the annular groove 35 presses against the axial protruding ends of all the notch frames 18, driving the notch frames 18 to move synchronously along the longitudinal groove 19, thereby simultaneously completing the angle adjustment of multiple sets of deformable grinding parts 7, realizing the synchronous adjustment of the angle of the arc surface grinding block 16, and ensuring that the arc surface grinding block 16 can conform to the arc surface contour of the shell during the grinding process.

[0036] In one embodiment, the locking assembly 9 includes an upper bracket 36 fixedly connected to the frame 10. The upper bracket 36 is movably mounted on the limiting rotating frame 28. The upper bracket 36 is movably connected to a bracket 37 movably connected to a limiting block 32. The bracket 37 is connected to a screw 38 threadedly connected to the upper bracket 36. After tightening the screw 38, the bracket 37 and the limiting block 32 mate and limit each other, thus locking the upper bracket 36 to the limiting rotating frame 28. When it is necessary to remove the deformed and ground part 7 for replacement, the bracket 37 can be pulled out by loosening the screw 38, and the upper bracket 36 can be removed from the limiting rotating frame 28 as a whole, completing the quick disassembly and replacement operation.

[0037] In one embodiment, the displacement drive unit 8 includes an electric telescopic rod 39 fixedly connected to the synchronous frame 27. A rotating support base 40 is fixedly connected to the moving end of the electric telescopic rod 39. A pressure head 41 is rotatably connected to the rotating support base 40. The electric telescopic rod 39, rotating support base 40, and pressure head 41 are all positioned above the longitudinal transfer frame 14. When grinding a flat surface is required, the electric telescopic rod 39 drives the rotating support base 40 and pressure head 41 to move downwards. The pressure head 41 presses down on the longitudinal transfer frame 14, compressing the spring 13, causing the flat grinding block 15 to abut against the housing surface, thereby performing grinding operations on the flat surface independently. The pressure head 41 can rotate on the rotating support base 40, adapting to the rotation of the longitudinal transfer frame 14 without causing motion interference.

[0038] Example 2, based on Example 1, see [link / reference] Figure 1 and Figure 2 The movable support structure 20 includes a movable stage 42 slidably connected to the frame 1. A worktable 43 is fixedly installed on the movable stage 42 and positioned below the arc-shaped grinding block 16. A third electric telescopic frame 44 is fixedly connected to the frame 1, and the movable end of the third electric telescopic frame 44 is fixedly connected to the movable stage 42. After the shell to be processed is placed and fixed on the worktable 43, the third electric telescopic frame 44 can drive the movable stage 42 to slide along the surface of the frame 1, thereby adjusting the initial position of the shell. This facilitates the double precision alignment of the processing position with the movable part 4, further improving the flexibility of position adjustment and reducing the difficulty of alignment adjustment.
