Description

Technical Field

[0001] The utility model relates to the technical field of chamfering processing, in particular to an automobile bushing chamfering device. Background Art

[0002] Although the existing bushing chamfering equipment has been continuously innovated and developed and basically meets people's needs, there is still room for improvement.

[0003] For example, the patent document with the announcement number CN207952817U discloses an automatic chamfering device for automobile bushings, including a base, a support column, and a control console. A fixed platform is provided on the top of the base, and the fixed platform is welded to the base. The automatic chamfering device for automobile bushings controls the movement of the processing tool through the control console, which makes it less likely for the bushing to be misplaced during processing, and also avoids processing deviations caused by manual operation errors, thereby improving its processing accuracy. While the bushing is being processed, the air tank is provided to blow away the residues attached to the processing through the air guide pipe, which ensures the smooth completion of its processing work. The overall degree of automation is high, which improves the processing efficiency of the bushing. A special guard plate is also provided to prevent waste from overflowing, which is beneficial to its later maintenance and use, and extends its service life.

[0004] Although the above-mentioned chamfering equipment can blow away the debris and cool the tool, the blown debris is easy to fly around and needs to be cleaned up again. Traditionally, suction equipment is also used to collect the debris. Smaller debris can easily pass through the filter and cause damage to the fan blades. There are still certain inconveniences in actual use. Therefore, there is an urgent need for an automobile bushing chamfering device to solve the above problems. Utility Model Content
