摘要:
An impact tool which provides a consistent level of impact force is provided. The internal mechanism of the impact tool has a trip release member and a hammer which remains in constant contact over a constant surface area throughout cycling of the impact tool. Additionally, the trip release member may slide against a slug having a straight conical surface to minimize variation. Moreover, the hammer may be non-rotateable so that a non round or asymmetrical head may be used.

An automatic dotting machine (100) includes a feeding device (10) for unloading workpieces (200) one by one with the same interval, a conveying device (40) for conveying the workpieces to a predetermined dotting region, a sensor unit (70, 251) for detecting whether the workpieces reach the predetermined dotting region, a programmed control unit (30) for controlling the whole process of the dotting and receiving signal detected by the sensor unit and then sending out a command, a sliding device for moving the workpieces to a predetermined dotting position after receiving the command of the programmed control unit, a positioning device for clamping and positioning the wokpieces to the predetermined position to be dotted, and a punching device (24) for punching dents on the workpieces after the workpieces are positioned at the predetermined position.
摘要:
An automatic optical center punch adapted to perform with high accuracy and ease of use is disclosed. The punch includes a spring-loaded hammer and a rotational latch mechanism. The rotational latch mechanism restrains the movement of the hammer to allow the spring to be compressed when pressure is initially applied to the punch by its operator. When the spring is fully compressed, the latch mechanism engages a cam surface, which causes the latch to rotate to release the hammer. The spring-loaded hammer makes contact with a punch head assembly, which causes perforation of the work surface to take place. Once the hammer has been extended by the spring, the latch engages a second cam surface, which causes the latch to rotate in the opposite direction to restrain the hammer in preparation for the next compression of the spring.
