Description

Technical Field

[0001] This utility model relates to the field of steel plate processing technology, and in particular to a polishing and deburring device. Background Technology

[0002] In the existing technology, steel plates are commonly used materials in the machining process. During the processing of steel plates, they need to be cut. During the cutting process, burrs and weld beads will appear on the cut surface, which needs to be further polished to ensure that the smoothness of the cut surface can meet the production and processing standards.

[0003] A search revealed Chinese patent application number 202421084866.0, which discloses a steel plate polishing and deburring device. The device includes a base with a support column fixedly connected to its bottom. Multiple feeding rollers are installed in the base. A leveling mechanism and a pressing mechanism are installed on the top of the base. The pressing mechanism is located behind the leveling mechanism. Two sets of first grinding mechanisms are located at the bottom of the leveling mechanism. A second grinding mechanism is installed at the bottom of the pressing mechanism. A cleaning mechanism is located behind the pressing mechanism and installed on the top of the base. A collection box is located below the cleaning mechanism and slidably connected to the base. The cleaning mechanism includes a fixed frame fixedly connected to the top of the base. A rectangular box is fixedly connected to the bottom of the top plate of the fixed frame. A spring is installed in the rectangular box. A connecting seat is located below the spring. The top of the connecting seat is slidably connected to the rectangular box. A sliding frame is fixedly connected to the bottom of the connecting seat and slidably connected to the inner wall of the fixed frame. A cleaning plate is fixedly connected to the bottom of the sliding frame.

[0004] The above-mentioned patent has the following shortcomings: The device polishes and deburrs the side of the steel plate by using the first grinding roller, but there is no burr and debris collection device around the first grinding roller. During the grinding process, the grinding roller rotates at high speed, and the burrs ground off will generate a large amount of kinetic energy. Only some burr and debris will remain on the surface of the steel plate, while other debris will fly out under the action of kinetic energy, affecting the collection of burr and debris.

[0034] A rotating connecting seat 8 is fixedly installed on the back of the protective groove arm 5 near the mounting pin 6. A rotating connecting head 9 is fixedly installed inside the rotating connecting seat 8. A connecting slide rod 10 is welded to the back of the rotating connecting head 9.

[0035] A slide rod sleeve 11 is slidably sleeved on the outer wall of the connecting slide rod 10. A sleeve cap 12 is threaded onto the tail end of the slide rod sleeve 11. The tail end of the connecting slide rod 10 passes through the sleeve cap 12. A support spring 26 is provided inside the connecting sleeve cap 12.

[0036] Both ends of the back of the U-shaped protective plate frame 1 are provided with sleeve adapter grooves 13.

[0038] Two mounting rings 27 are symmetrically welded to the bottom end of the U-shaped protective plate frame 1. The inner cavity of the mounting ring 27 is connected to the inner cavity of the U-shaped protective plate frame 1, which facilitates the removal of burrs and debris from inside the U-shaped protective plate frame 1.

[0039] The outer wall of the mounting ring 27 is threaded with a guide mounting bucket 20. The bottom end of the guide mounting bucket 20 is fixedly mounted with a guide connecting pipe 19. The bottom ends of the two guide connecting pipes 19 are welded with burr and debris collection boxes 15.

The burr and debris filter plate frame 28 is used to filter burrs and debris in the airflow.

[0041] Working principle:

[0042] Please refer to Figures 1 to 6 Assemble the device as shown in the figure;

[0043] When using this device, the steel plate is first fixed, and then the brushless motor 3 and the high-flow fan 18 are started simultaneously. The brushless motor 3 drives the grinding spindle 21 to rotate at high speed through the coupling 4, and the grinding spindle 21 drives the steel plate grinding roller 23 to rotate synchronously. The high-flow fan 18 draws air from inside the U-shaped protective plate frame 1. The air enters the burr and debris collection box 15 through the guide installation bucket 20 and the guide connecting pipe 19. After being filtered by the burr and debris filter plate frame 28, it is discharged by the high-flow fan 18. Then, the edge of the steel plate that needs to be polished and ground is inserted into the front opening of the U-shaped protective plate frame 1. Then, the U-shaped protective plate frame 1 is pushed (by external force, such as a cylinder) to squeeze the steel plate against the two auxiliary rollers 7, thereby generating a thrust on the protective groove arm 5. The pushing connection slide rod 10 of the protective groove arm 5 causes the squeezing connection seat 25 to compress the support spring 26, until the edge of the steel plate is in contact with the outer wall of the steel plate grinding roller 23. Then, the U-shaped protective plate frame 1 is moved at a constant speed along the edge of the steel plate, so that the steel plate grinding roller 23 polishes the edge of the steel plate. Most of the burrs and debris generated during the polishing are carried into the burr and debris collection box 15 by the airflow and filtered and collected by the burr and debris filter plate frame 28.

[0044] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
