The invention provides rust removing equipment for machining. The rust removing equipment comprises a master control switch and a power plug. Four supporting columns are mounted on the outer wall of arust removing inner cylinder, and a feeding hole is formed in the top of the left side end face of the rust removing inner cylinder and communicates with the bottom of a feeding funnel; a discharginghole is formed in the bottom of the right side end face of the rust removing inner cylinder, a gate plate is mounted at the discharging hole, and one end of the gate plate is slidablyconnected with the interior of the rust removing inner cylinder; and a rust leaking hole is formed in the bottom of the rust removing inner cylinder and located in the top of a rust residue collecting drawer. Grinding balls and the outer walls of mechanical parts makes mutual friction advantageouslythrough rotating of a rust removing rotating cylinder, and rust contained in the exteriors of the mechanical parts is removed, so that the exteriors of the mechanical parts are smoother and cleaner, and the mechanical parts can conveniently assembled and used by people; the rust removing rotating cylinder is arranged obliquely so thatpeople can discharge the mechanical parts convenientlythrough rotating of the rust removing rotating cylinder, physical labor of people is reduced, and the working efficiency is promoted.

The invention belongs to the technical field of machinery and relates to a double-person workbench, which solves the technical problems of low work efficiency when two people simultaneously assemble and process the same product in the prior art. The two-person workbench includes a bracket. The bracket has a space for installing the link mechanism along its own length. The link mechanism includes the first link, the second link and the cross bar. The length of the first link and the second link is 25 pieces. Unit length, the lower end of connecting rod 1 and the lower end of connecting rod 2 are both hinged on the bracket, and the distance between the lower hinge point of connecting rod 1 and the lower hinge point of connecting rod 2 is 20 unit lengths, the The upper end and the upper end of the connecting rod 2 are respectively hinged with the two ends of the cross bar. The length of the cross bar is 10 unit lengths. The upper surface of the cross bar is provided with a positioning device for fixing the workpiece to be assembled. A driving device for swinging of rod one and / or connecting rod two. The two-person workbench can effectively improve assembly efficiency.

The invention provides a high-accuracy visual coaxial optical alignment assembly system for a miniature structural member. The system comprises a manipulator, a light source, an optical alignment device, a micro-positioning platform, an image pick-up device and a control device, wherein the image pick-up device and the optical alignment device are positioned on the same horizontal line; and the manipulator and the micro-positioning platform are positioned above and below the optical alignment device respectively. A local template is used, images of both a base member and a member to be arranged are binary images, and a binary edge only exists in the template matching process, so the calculated amount is greatly reduced and the speed is improved during matching, and the requirement on a positioning real-time property is met. The local template is used for searching an accurate alignment pixel coordinate and a directional line included angle of the base member and the member to be arranged, and the micro-positioning platform is adjusted under control of a control signal generated by the system, so that the system has higher alignment accuracy.

Disclosed are a vector expressing poliomyelitis virus-like granule proteins and a method for preparing poliomyelitis virus-like granules. The vector contains expression cassettes of the following structure: any one of three genes of poliomyelitis virus structural proteins i.e. VP0, VP1, VP3, is located in the downstream of promoter 1, and the other two are connected to the downstream of promoter 2 by a 2A sequence. The promoting expressions directions of the two promoters are opposite. The method for preparing poliomyelitis virus-like granules is that the corresponding host cells are transfected with the vector. After cultivation, virus-like granules and recombinant baculoviruses can be obtained. If what are obtained are the recombinant baculoviruses, then the host cells are infected with the viruses, and virus-like granules can be obtained.
