Description

Technical Field

[0001] The utility model relates to the technical field of detection, in particular to a workpiece size detection device. Background Art

[0002] Before a workpiece leaves the factory, the dimensions of each part of it need to be inspected. If a dimensional error exceeding the tolerance is found, it is a defective product and is not allowed to leave the factory. In the industrial production process, cylindrical workpieces made of relatively soft materials (such as copper, aluminum and other non-ferrous metals) are often required, and such workpieces must also be inspected for dimensional accuracy before leaving the factory. The traditional inspection method is to place a large number of workpieces in a vibrating feeder, which transports such workpieces one by one to the inspection station for inspection of their appearance dimensions. The commonly used inspection and measurement tools are represented by vernier calipers, but the manual inspection method has many problems such as low work efficiency, high labor workload, and false detection. Therefore, a method or device that can solve the above problems is now needed.

[0003] To this end, the utility model provides a workpiece size detection device to solve the above-mentioned problem. When the cylindrical workpiece to be detected falls into the limit groove, the two-dimensional measuring instrument body can detect the workpiece. By starting the servo motor to drive the active gear to rotate and then drive the two driven teeth to rotate, the screw rod 23 will rotate, so that the assembly plate can move back and forth in a straight line, thereby adjusting the position of the two-dimensional measuring instrument body; through the cooperation of the telescopic cylinder and the clamping block, when the workpiece is detected to be qualified, the telescopic cylinder will start to push the clamping block to move, and the clamping block will clamp one end of the workpiece and push it out of the limit groove. If the workpiece is detected to be unqualified, the first electric push rod will start to push the unqualified workpiece upward, and then the second electric push rod will also start to push it to one side, so as to realize the separate processing of good and bad workpieces.
