The present invention discloses a deburring tool, a deburring system and a deburring method. The deburring tool comprises a floating cylinder, a floating piston, a spindle and a radial floating assembly. The floating cylinder is connected to an external device through a connecting piece. The floating cylinder is provided with a floating cavity running through it from top to bottom. The lower end of the floating cavity is provided with a limiting ring coaxially distributed therewith. The floating piston and the radial floating assembly are both arranged in the floating cavity. The radial floating assembly is distributed below the floating piston and contacts with the upper end of the limiting ring. The floating piston and the radial floating assembly are respectively provided with mounting holes running through them from top to bottom. The spindle passes through the mounting holes from top to bottom and is connected to the radial floating assembly. The deburring tool described in the present application has good quality in removing burrs. The present application also proposes a deburring system and a deburring method based on the deburring tool, which can realize high-quality, high-precision and high-stability deburring processing on the workpiece surface.

This invention relates to the field of automotive component structure technology, specifically to a high-braking lamp mounting structure and disassembly method. It includes a trunk lid and a high-braking lamp. The trunk lid comprises an inner panel and an outer panel. When the trunk lid is closed, the outer panel has a mounting groove recessed downwards in the Z direction at its X-axis front end. The high-braking lamp is mounted within the mounting groove, and when the trunk lid is closed, the X-axis front end of the high-braking lamp connects to the X-axis rear end of the rear windshield. A fixing structure for securing the high-braking lamp within the mounting groove and an arrangement structure for facilitating the installation of wiring harnesses on the high-braking lamp are provided between the inner panel, outer panel, and high-braking lamp. The high-braking lamp mounting structure of this application is very simple. The high-braking lamp is located outside the rear windshield, unobstructed, easy to install and disassemble, increases the storage capacity of the rear cargo area while increasing the luminous area of ​​the high-braking lamp, and has significant potential for widespread application.

The invention provides a method and a system for calculating an equivalent included angle of an electric drive transmission shaft of a whole vehicle, a terminal and a medium. The method comprises the following steps: acquiring three-dimensional coordinates of three reference points randomly marked on a circular section of a preset position of the transmission shaft; based on the three-dimensional coordinates of the three reference points on the circular section, calculating to obtain a circle center three-dimensional coordinate of the circular section of the preset position of the transmission shaft; checking the circle center three-dimensional coordinates of the circular section of the preset position of the transmission shaft to obtain the calibrated circle center three-dimensional coordinates of the circular section of the preset position; calculating an included angle between an electric drive output shaft and a front transmission shaft, an included angle between the front transmission shaft and a rear transmission shaft and an included angle between the rear transmission shaft and a drive axle input shaft based on the three-dimensional coordinates of the transmission shaft preset position circular section calibration center; based on the included angle between the electric drive output shaft and the front transmission shaft, the included angle between the front transmission shaft and the rear transmission shaft and the included angle between the rear transmission shaft and the drive axle input shaft, the transmission shaft equivalent included angle is calculated. The equivalent included angle can be accurately and efficiently measured and calculated.
