Abstract: A screw locking device includes a feeding mechanism, a conveying mechanism, and a pneumatic screw driver. The conveying mechanism includes a base, a pneumatic driver slidably mounted on the base, a pair of blocking members slidably mounted on the base, a conveying bridge, a flexible tube, and a controller. Each blocking member includes a blocking end positioned below the pneumatic driver. The conveying bridge communicates with the feeding mechanism, and extends to the blocking ends. The flexible tube aligned with a gap between the blocking ends, and communicates with the pneumatic screw driver.

Abstract: A screw-removing device used for removing a number of screws screwed into a workpiece includes a support frame, a removing mechanism, a positioning mechanism, and a transporting mechanism. The removing mechanism includes a first driving member mounted on the support frame and a number of universal shafts. The universal shaft comprises a main body, a transmitting portion connected to the first driving member, and a connection portion. A removing member is connected to the connection portion. The positioning mechanism is mounted in the support frame to position the workpiece below the removing member. The transporting mechanism is mounted on the support frame to transport the workpiece to the positioning mechanism.

Abstract: A fetching mechanism includes a support base, a fetching member positioned on the support base and an adsorbing assembly. The adsorbing assembly is positioned on the support base and is spaced from the fetching member. The adsorbing assembly includes a driving member positioned on the support base and an adsorbing member driven by the driving member. The fetching member fetches one welding member, the adsorbing member is driven by the driving member to extend out and adsorbs the workpiece, and the adsorbing member is driven to drawback until each welding member attaches the workpiece. The application also supplies an automatic welding system using the fetching mechanism.

Abstract: A deburring device, for removing burrs off an inner sidewall of a hole of a workpiece, includes a mounting seat, a first driving member, an elastic coupler, a cutter, a polisher assembly, an elastic coupler, and a controller. The first driving member is mounted on the mounting seat. The cutter is connected to the first driving member by the elastic coupler. The polishing assembly is assembled to the mounting seat and arranged opposite to the cutter, in which the controller is electrically connected to the first driving member and the polisher assembly. The controller controls the cutter to enter the hole of the workpiece and mill the inner sidewall of the hole of the workpiece to remove burrs off the workpiece, the polishing pad moves to remove burrs generated by the cutter.

Abstract: A hanging module includes a fixing rod, a support arm, a plurality of fasteners, and a hanging assembly positioned on the support arm by the plurality of fasteners. The support arm is fixed to the fixing rod. The support arm defines a groove. The hanging assembly includes a locking member and a hanging member fixed to the locking member. The hanging member is received in the groove, and fixed to the locking member by the plurality of fasteners.

Abstract: A polishing device is disclosed. The polishing device includes a load seat and two polishing mechanisms mounted on the load seat. Each polishing mechanism includes a driving member and a polishing member driven by the driving member. The two polishing members of the two polishing mechanisms are oppositely received in the receiving space, and oppositely rotatable driven by the corresponding driving member. The polishing members are rotated oppositely, such that the new burs generated by one of the polishing members can be removed by other one of the polishing members at the same time.

Abstract: A positioning structure includes a positioning base, a positioning member, a mounting member, a ball, and an elastic member. The positioning base defines a fastening hole. The positioning member is positioned in the fastening hole. The mounting member includes a fixing portion and an assembling portion extending from the fixing portion. The assembling portion is inserted into the positioning member. The fixing portion defines a receiving groove extending to the assembling portion. The assembling portion defines an exposing hole communicating with the receiving groove. The ball is received in the exposing hole. The elastic member is movably inserted into the receiving groove, and resists the ball to be partly exposed from the exposing hole to abut the positioning member, which enable the positioning base to be positioned on the machining device. The present disclosure further provides a machining device using the positioning structure.

Abstract: A size inspection device includes a detecting platform, a positioning assembly, four first detecting assemblies, four second detecting assemblies, a third detecting assembly, and a controller. The detecting platform includes a mounting plate. The positioning assembly is detachably mounted on the mounting plate for holding the workpiece on the detecting platform. The controller is electronically connected to the first detecting assemblies, the second detecting assemblies, and the third detecting assembly. The four first detecting assemblies and the four second detecting assemblies are slidably mounted on the mounting plate and are capable of obtaining a first moving distance and a second moving distance respectively. The third detecting assembly is mounted on the mounting plate and is capable of obtaining a third moving distance. The controller obtains the moving distances and determines whether or not the workpiece is of passing or failing quality.
