[0007] The external processing component is composed of a driving part and a grinding part, and the grinding part includes a plurality of rotating shafts, and the rotating shafts penetrate and are rotatably connected with the side walls of the external processing box, and an external grinding column is fixed to the side wall of the rotating shaft, and a slide groove is opened on the side wall of the external grinding column, and a baffle is fixed to the port of the slide groove, and the inner wall of the slide groove is connected to an adjustment plate through an adjustment spring, and a plurality of steel wires are fixed to the side wall of the adjustment plate, and the steel wires penetrate the baffle, and an adjustment block is embedded in the inner wall of the slide groove, and the adjustment block is an electromagnet.

[0008] In the above-mentioned casting housing burr removal device for motor processing, the driving part includes an external grinding motor installed on the outer wall of the outer processing box, and the output shaft of the external grinding motor is fixed to one of the ends of the rotating shaft.

[0009] In the above-mentioned casting housing burr removal device for motor processing, the ends of the plurality of rotating shafts are respectively installed with a filling gear and an offset gear, and the filling gear and the offset gear are staggered and meshed with each other.

[0010] In the above-mentioned casting shell burr removal device for motor processing, the internal processing component includes an internal processing motor installed at the bottom of the operating table, the output shaft of the internal processing motor is fixed with a mounting column, the upper end of the mounting column is connected to a sliding frame through a yield spring, the side wall of the sliding frame is rotatably connected to a plurality of push rods, and the ends of the push rods are rotatably connected to grinding plates.

[0011] In the above-mentioned casting housing burr removal device for motor processing, the mounting plate is an electromagnet and has an adsorption effect on the sliding frame, a plurality of limit frames are fixed to the side wall of the mounting column, and the side wall of the push rod abuts against the inner wall of the limit frame.

[0012] In the above-mentioned casting housing burr removal device for motor processing, the propulsion clamping assembly includes a push rod installed on a propulsion frame, a pressure box is fixed to the end of the push rod, two symmetrically arranged clamping boxes are fixed to the end of the pressure box, and the side wall seal of the clamping box is penetrated by a plurality of clamping plates that are slidably connected.

[0013] In the above-mentioned casting housing burr removal device for motor processing, the pressure box is connected to the clamping box and is filled with hydraulic oil. The inner wall of the pressure box is sealed and slidably connected with a pressure plate. The side wall of the pressure box is installed with a cylinder, and the end of the cylinder is fixed to the pressure plate.

[0016] Compared with the prior art, the advantages of the present invention are:

[0017] 1. The carrying plate is an electromagnet and has an adsorption effect on the sliding frame. When the carrying plate is energized, it attracts the sliding frame to move downward, so that the top rod moves downward and deflects, causing the grinding plate to expand outward, thereby abutting against the inner wall of the workpiece to be processed, thereby achieving internal support and fixation of the workpiece to be processed. When performing external grinding, it can ensure comprehensive external grinding treatment;

[0018] 2. The side wall of the push rod is against the inner wall of the limit frame, and the limit frame drives the side wall of the push rod. Therefore, during the rotation of the installation column, the force point is not a single rotation position, thereby avoiding the breakage of the connection position of the push rod;

[0019] 3. During the rotation of the outer grinding column, the adjustment plate under the centrifugal force will expand outward, causing the steel wire to extend outward, and the degree of expansion can be controlled by controlling the rotation speed, so that the grinding range of the steel wire can be adjusted, mainly adjusting the grinding depth, so that the heat dissipation rib gap of the workpiece can be effectively ground, and it can adapt to heat dissipation ribs of various heights;

[0020] 4. The regulating block will generate a magnetic field after being energized, thereby attracting the regulating plate, so that the regulating plate can be close to the regulating block, thereby overcoming the large centrifugal effect. Therefore, under the condition of ensuring the grinding speed, the steel wire can be prevented from extending too long outward, thereby reducing the wear on the steel wire;

[0021] 5. The positions of the adjustment plates inside the multiple slides can be adjusted to be different, so that the grinding depth of each position of the external grinding column of a certain thickness is also different, so as to match the circular workpiece to be processed, so that during the rotary processing of the workpiece to be processed, the grinding effect of each position is basically the same, thereby improving the overall grinding efficiency;

[0022] 6. The corresponding outer grinding column can rotate in the opposite direction, so that the grinding rotation direction is opposite, so that the force on the workpiece is basically balanced, and there will be no vertical movement due to grinding in a single direction; and the staggered arrangement of the outer grinding columns with different directions can achieve vertical full coverage of the grinding position and ensure comprehensive grinding treatment;

[0023] 7. Multiple clamping plates can move independently, so it is possible to achieve filling clamping of uneven surface structures of the workpiece to be processed, which greatly improves the clamping effect of the workpiece to be processed;

[0024] 8. When the fixed plate vibrates up and down at high speed, the outer ring and the inner ring will vibrate up and down accordingly, so that the bristles can fully brush the surface of the workpiece, and the surface treatment is more refined through high-frequency treatment.

DETAILED DESCRIPTION

[0043] The following examples are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0044] Example

[0045] Reference Figures 1 to 5A burr removal device for a casting housing used for motor processing comprises a processing table 1, a transposition motor 3 is installed on the inner bottom of the processing table 1, an operating table 4 is installed on the output shaft of the transposition motor 3, the transposition motor 3 drives the operating table 4 to rotate, a carrying plate 5 is installed on the upper end of the operating table 4, a workpiece 2 to be processed is installed on the carrying plate 5, an internal processing component is arranged on the carrying plate 5, and two groups of internal processing components can be arranged. During the rotation of the operating table 4, two groups of workpieces 2 to be processed can enter different processes one after another, thereby realizing continuous processing and improving the processing efficiency;

[0046] An external processing box 6 is installed on the inner wall of the processing table 1, and an external processing component is arranged inside the external processing box 6. The internal processing component clamps the workpiece 2 to be processed internally, so that the external processing component can process the external heat dissipation ribs of the workpiece 2, and can drive the workpiece 2 to be processed to rotate, so as to realize the rotation and comprehensive grinding. A pushing frame 7 is installed on the side wall of the processing table 1, and a pushing clamping component is installed on the pushing frame 7. The pushing clamping component clamps the workpiece 2 to be processed externally, so that the internal processing component changes from internal clamping to internal grinding. A lifting frame 8 is installed on the top of the processing table 1, and a lifting rod 33 is installed at the bottom of the lifting frame 8. The bottom of the lifting rod 33 is connected to a fine processing component, and the lifting rod 33 pushes the fine processing component downward to cover the workpiece 2 to be processed, so that the fine processing component can perform the final fine grinding treatment on the workpiece 2 to be processed;

[0047] Reference Figure 6 and Figure 7 The internal processing component includes an internal processing motor 9 installed at the bottom of the operating table 4. The output shaft of the internal processing motor 9 is fixed with a mounting column 10. The upper end of the mounting column 10 is connected to a sliding frame 12 through a yield spring 11. The side wall of the sliding frame 12 is rotatably connected with a plurality of push rods 13. The ends of the push rods 13 are rotatably connected with a grinding plate 14. The internal processing motor 9 drives the mounting column 10 to rotate, thereby causing the push rods 13 and the grinding plate 14 to rotate. When the workpiece 2 to be processed is not subject to external restrictions, the workpiece 2 to be processed will be synchronously driven to rotate. When the workpiece 2 to be processed is subject to external restrictions, the rotation of the grinding plate 14 will grind the inside of the workpiece 2 to be processed.

[0048] The carrying plate 5 is an electromagnet and has an adsorption effect on the sliding frame 12. When the carrying plate 5 is energized, the sliding frame 12 is attracted to move downward, so that the push rod 13 moves downward and deflects, so that the grinding plate 14 expands outward, thereby abutting against the inner wall of the workpiece 2 to achieve internal support and fixation of the workpiece 2. After the carrying plate 5 is powered off, the sliding frame 12 moves upward under the elastic force of the yield spring 11, so that the push rod 13 moves upward and drives the grinding plate 14 to retract and reset. A plurality of limit frames 15 are fixed to the side wall of the mounting column 10. The side wall of the push rod 13 abuts against the inner wall of the limit frame 15. The limit frame 15 drives the side wall of the push rod 13. Therefore, during the rotation of the mounting column 10, the force point is not a single rotation position, thereby avoiding the breakage of the connection position of the push rod 13.

[0049] Reference Figures 8 to 11 The external processing component is composed of a driving part and a grinding part. The grinding part includes a plurality of rotating shafts 16. The rotating shafts 16 are rotatably connected with the side walls of the external processing box 6. An external grinding column 19 is fixed to the side wall of the rotating shaft 16. The rotation of the rotating shaft 16 drives the external grinding column 19 to rotate. A slide groove 21 is provided on the side wall of the external grinding column 19. There are multiple slide grooves 21, so as to improve the coverage. A baffle 26 is fixed to the port of the slide groove 21. The inner wall of the slide groove 21 is connected with an adjusting plate 23 through an adjusting spring 22. A plurality of steel wires 25 are fixed to the side wall of the adjusting plate 23. The steel wire 25 penetrates the baffle 26. During the rotation of the external grinding column 19, the adjusting plate 23 subjected to the centrifugal force will expand outward, so that the steel wire 25 extends outward, and the degree of expansion can be controlled by controlling the rotation speed, so that the grinding range of the steel wire 25 can be adjusted, mainly adjusting the grinding depth, so that the heat dissipation rib gap of the workpiece 2 can be effectively ground, and it can adapt to heat dissipation ribs of various heights.

[0050] An adjusting block 24 is embedded in the inner wall of the slide groove 21. The adjusting block 24 is an electromagnet. When powered on, the adjusting block 24 generates a magnetic field, thereby attracting the adjusting plate 23, so that the adjusting plate 23 can approach the adjusting block 24, thereby overcoming the large centrifugal effect. Therefore, under the condition of ensuring the grinding speed, the steel wire 25 can be prevented from extending too long outward, thereby reducing the wear on the steel wire 25. In addition, the positions of the adjusting plates 23 inside the multiple slide grooves 21 can be adjusted to be different, so that the grinding depth of each position of the outer grinding column 19 of a certain thickness is also different, so as to match the circular workpiece 2 to be processed, so that during the rotary processing of the workpiece 2 to be processed, the grinding effect of each position is basically the same, thereby improving the overall grinding efficiency.

[0051] The driving part includes an external grinding motor 20 installed on the outer wall of the external processing box 6, the output shaft of the external grinding motor 20 is fixed to the end of one of the rotating shafts 16, and the ends of the multiple rotating shafts 16 are respectively installed with a supplementary gear 17 and a staggered gear 18, which are staggered and meshed with each other. The rotation is transmitted by the meshing of the supplementary gear 17 and the staggered gear 18, thereby reducing the number of motors installed, and the control is more convenient and stable. In addition, when the supplementary gear 17 and the staggered gear 18 are meshed, the rotation directions are opposite, so that the corresponding rotating shaft 16 rotates in the opposite direction, so that the corresponding external grinding column 19 can rotate in the opposite direction, so that the grinding rotation direction is opposite, and then the force on the workpiece 2 to be processed is basically balanced, and no vertical movement will occur due to grinding in a single direction;

[0052] And the staggered arrangement of the outer grinding columns 19 of different directions can achieve vertical full coverage of the grinding positions and ensure comprehensive grinding treatment;

[0053] Reference Figure 12 to Figure 14 The pushing and clamping assembly includes a push rod 27 installed on the pushing frame 7, a pressure box 28 is fixed at the end of the push rod 27, and two symmetrically arranged clamping boxes 29 are fixed at the end of the pressure box 28. The push rod 27 pushes the pressure box 28 to move, thereby moving the two clamping boxes 29, so that after the workpiece 2 to be processed is rotated into place, the clamping box 29 is moved so that the workpiece 2 to be processed is located between the two clamping boxes 29. The side wall seal of the clamping box 29 is penetrated and slidably connected with multiple clamping plates 32. The clamping plate 32 is a thin plate structure, is provided with multiple and can move independently.

[0054] The pressure box 28 is connected to the clamping box 29 and filled with hydraulic oil. The inner wall of the pressure box 28 is sealed and slidably connected with a pressure plate 31. The side wall of the pressure box 28 is installed with a cylinder 30. The end of the cylinder 30 is fixed to the pressure plate 31. The cylinder 30 pushes the pressure plate 31 to move, so that the hydraulic oil is transferred from the pressure box 28 to the clamping box 29 under pressure, so that the clamping plate 32 inside the clamping box 29 moves outward under the action of hydraulic pressure, so that the clamping plate 32 can perform external clamping treatment on the workpiece 2 to be processed. Since multiple clamping plates 32 can move independently, it is possible to achieve filling-type clamping of the uneven surface structure of the workpiece 2 to be processed, so that the clamping effect of the workpiece 2 to be processed is greatly improved. After the workpiece 2 to be processed is clamped externally, it can be internally polished.

[0055] Reference Figures 15 to 17The fine processing component includes a fixing plate 36. The fixing plate 36 and the adsorption plate 34 are jointly fixed with a plurality of shaking springs 35. The adsorption plate 34 is an electromagnet and has an adsorption effect on the fixing plate 36. When the adsorption plate 34 is energized, a magnetic field is generated, thereby attracting the fixing plate 36, so that the fixing plate 36 moves upward. After the power is cut off, the fixing plate 36 is reset under the elastic force of the shaking spring 35. When the adsorption plate 34 is reciprocatedly powered on and off, high-speed shaking of the fixing plate 36 can be achieved. At this time, the workpiece 2 to be processed is adsorbed by the magnetic force of the carrying plate 5 and remains stable. However, the magnetic field of the carrying plate 5 is weaker than the internal support state, so the top rod 13 will not be unfolded, and will not affect the fine processing. When there is no external force to fix the workpiece 2 to be processed, the carrying plate 5 is energized to generate a magnetic field to maintain the stability of the workpiece 2 to a certain extent.

[0056] An outer ring 37 and an inner ring 38 are installed at the bottom of the fixed plate 36, and bristles 39 are fixed to the inside of the outer ring 37 and the outside of the inner ring 38. When the fixed plate 36 shakes up and down at high speed, the outer ring 37 and the inner ring 38 will shake up and down accordingly, so that the bristles 39 can comprehensively brush the surface of the workpiece 2, and make the surface treatment more refined through high-frequency treatment.

[0057] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
