A method for selecting and / or labeling a vessel image includes operating an imaging system to obtain reconstructed image data including a volume having vessels therein. A bone removal routine is then applied to the reconstructed image data to produce a bone-free image. An initial point on a main vessel in the bone-free image is located, and bifurcation points and branches departing from the main vessel are identified. An adjacency graph of each branch coming from the main vessel is built. The method includes either or both of selecting and displaying a best or at least a favorable path through the vessels in accordance with predetermined criteria using the adjacency branch, or labeling and displaying branches of the main vessel.

The invention relates to a method and a device for testing an automobile plastic part. The device comprises a base plate, a positioning base, a profile normalization module and a detection module, and the positioning base, the profile normalization module and the detection module are in sequential connection and arranged on the base plate. The profile normalization module and the plastic part are uniform in shape, the profile normalization module hermetically surrounds the positioning base, and the detection module is positioned on the outer side of the profile normalization module. The method includes: embedding the plastic part into the positioning base, judging whether the plastic part is completely embedded or not, and if not, determining that the plastic part is unqualified; if yes, adopting the detection module and a filler gauge to detect dimensions of the plastic part, judging whether the dimensions of the plastic part are qualified or not, and if not, determining that the plastic part is unqualified; if yes, detecting a plane warping degree of the plastic part by the aid of a flush go / no-go gauge, judging whether the plane warping degree of the plastic part is qualified or not, if yes, determining that the plastic part passes testing, and if not, determining that the plastic part is unqualified. Compared with the prior art, the method and the device for testing the automobile plastic part have advantages of testing accuracy, high operation efficiency, cost saving, high practicality and the like.

The invention discloses a safe screw assembling device capable of automatically feeding and synchronously assembling and disassembling workpieces, comprising a stand, a power device, a spinning tool feed unit, a spinning tool engaging and disengaging mechanism, a fastening screw guide device, an angle adjusting workbench, an automatic base feed unit and a synchronous base assembling and disassembling device. A mode that the piston rod of an air cylinder drives a push rod to enter and exit is adopted, an interior mirror base is automatically fed into a station, manual operation steps are saved, and the production efficiency is greatly increased; due to the adoption of the spinning tool engaging and disengaging mechanism, the required thread spinning length can be precisely realized, and meanwhile, screw holes are effectively prevented from being damaged by screwing or screws are effectively prevented from sliding; the rotating speed of a spinning tool can be changed along with the replacement of a speed reducing belt pulley, and the applicable range is wide; a fastening screw needs not to be positioned manually and can be precisely positioned by an operator through throwing the fastening screw in the fastening screw guide device along the approximate direction, and the labor intensity of the operator is effectively reduced; the assembled interior mirror base can be automatically detached, the production efficiency is further improved, and the labor intensity is further reduced.

The invention relates to the technical field of auto parts processing, and discloses a grinding device for auto parts, which includes a frame and a motor. A main bevel gear is fixed on the output shaft of the motor; a support shaft is provided at the bottom of the main bevel gear, and both sides of the support shaft There is a friction plate on the side that is slidingly connected to the main bevel gear. There are bumps fixed on the friction plates, and compression springs are fixed between the bumps. The bottoms of the friction plates are inclined planes that slope downward toward the support shaft; below the main bevel gear It is also equipped with a telescopic cylinder and a support seat. The support seat includes a fixed seat and a sliding seat. The telescopic rod of the telescopic cylinder is fixedly connected to the sliding seat. The sliding seat is slidingly connected with a positioning rod that cooperates with the friction plate. The bottom of the positioning rod is provided with a return spring. ; There is a auxiliary bevel gear rotatably connected to the frame, and the auxiliary bevel gear meshes with the main bevel gear. The frame is provided with a screw, the auxiliary bevel gear drives the screw to rotate, and the nut seat of the screw is fixedly connected to the fixed seat. The invention has a simple structure and can polish and remove burrs from the accessory holes and bottom surfaces of accessories.
