An automatic centerless grinding device comprises a machining mechanism, a feeding mechanism and a feeding and discharging mechanism. The processing mechanism comprises a supporting seat, a grinding wheel and a guide wheel; during machining, the guide wheel makes contact with the workpiece to drive the workpiece to rotate, and the grinding wheel grinds the surface of the workpiece. The feeding mechanism comprises a first feeding belt and a material disc, the material disc is used for containing workpieces, and the first feeding belt is used for conveying the material disc. The feeding and discharging mechanism is used for transferring the workpieces from the material disc to the workpiece supporting base for machining and transferring the machined workpieces from the workpiece supporting base to the material disc. Compared with the prior art, full-automatic feeding, machining and discharging can be achieved, the machining efficiency is remarkably improved, and the labor intensity of workers is reduced.

The utility model relates to punching equipment technical field, and disclose a new energy automobile frame processing is with punching equipment, including numerical control laser cutting machine, the workbench of numerical control laser cutting machine places the locating disc, the lower extreme of locating disc is close to both ends place and rotates and installs the support shaft, the left and right both ends of support shaft all are fixedly installed with double conical roller, the front and back both ends of numerical control laser cutting machine all are fixedly installed with the baffle, the inside of slide groove all slide and install square bearing, the inside between square bearing all are fixedly installed with two -way screw rod, the mobile block between in the similar one end all are fixedly connected with the angle and resist piece. The device can be more labor -saving and fast to move to the workbench with the cooperation of double conical roller and track, and meanwhile can fix the same batch chassis frame on another set of locating disc in advance, realizes the feeding and discharging fast, avoids lifting to the workbench and then carries out the tedious tooling positioning operation, improves the efficiency of overall processing procedure.

The mold ejection test equipment comprises a test rack, an ejection device used for carrying out an ejection test on an ejection structure of a mold, and a control device used for controlling the ejection device to work, the ejection device and the control device are both arranged on the test rack, and the control device is electrically connected with the ejection device. The utility model provides mold ejection test equipment, which enables a tester to find hidden problems of an ejection structure of a mold in time and ensures that the mold can work normally when being mounted on an injection molding machine.

The application discloses a kind of selection welding equipment welding height detection compensation device and method, it is related to PCB processing technical field, including three-axis transmission assembly, the three-axis transmission assembly includes the first transmission member of fixed setting, second transmission member is set to the output end of first transmission member, the output end of second transmission member is fixed with bearing frame, third transmission member is set on bearing frame, the output end of third transmission member is fixed with mounting bracket, welding assembly is set on mounting bracket, height detection component is set on bearing frame, the height detection component includes the support plate of being fixed on bearing frame.The application is measured and is compensated to welding point height by laser range finder in height detection component cooperation three-axis transmission assembly and centralized control component, avoid fixed height welding to uneven PCB board to cause component damage or welding bad, while reduce special-purpose carrier cost and feeding and discharging time.
