Spring chuck product clamping mechanisms have been widely used in metal cutting machines, especially in bar automata. However, their individual parts are often damaged, and the downtime caused by the clamping mechanism of the automaton is often significant. In all parts of the clamping mechanism, the spring chuck is an important part of Z. It works under intense motion conditions and determines the accuracy of processing. Therefore, it is very important to determine the basic parameters of the spring chuck (valve number, cone angle, jaw, and valve length) to ensure high working capacity.
In fact, Type II and Type III chucks are widely used. The number of chucks should be selected based on the accuracy and stiffness conditions of the bar clamping (the stability of the bar in the spring chuck). Spring clamping with an even number of lobes is mostly achieved by using radially opposed lobes when clamping the bar, allowing the bar to have some freedom of movement, which sharply reduces the clamping stiffness. On the contrary, for spring chucks with an odd number of flaps, it is usually seen that there are three small planes on the flap, which can ensure a more reliable clamping of the bar material. The measurement of the positional stability of a bar material with a diameter of 10 mm held in various types of spring chucks in Class III confirms the above hypothesis (the measurement was conducted at a distance of 30 mm from the end face of the spring chuck): Based on the large deviation (fair deviation) between two adjacent positions, it can be seen from the data that the Z principle is a spring clamp that uses a numerical force to rescue the loss. The stability of the bar position is consistent with the cone angle of the spring clip tip. Generally, the taper angle of the spring clip tip is made to be approximately 1 "larger than the taper angle of the matching miscellaneous hole, creating instability in the pinch position.
A spring chuck is a cylindrical clamp that can be used to attach a drill bit or milling cutter to a milling machine. Spring chuck is a fixing device used to fix and reinforce parts that need to be modified. Spring chuck spindle speed Spring chuck is often a good choice for turning at very high spindle speeds, mainly for two reasons. One reason is related to the quality of the chuck. Assuming that the chuck and spring chuck are driven at the same spindle horsepower, thicker and heavier chuck chucks require longer time to accelerate to the desired speed, Long acceleration times will extend the work cycle and reduce productivity. The workpiece size spring chuck is very suitable for workpieces with a diameter of less than 3 inches. Spring chucks have limitations on the length of the workpiece. In particular, spring chucks limit the axial travel range of the machine tool because their length is longer than the jaw chuck. When the processing length of the workpiece requires almost the entire available stroke of the machine tool, it is probably necessary to use a jaw chuck.
