Abstract

The invention relates to the technical field of cutter sleeves of horizontal machining centers, relates to a special device for replacing a broach spring and a using method thereof, and aims to conveniently realize the replacement of the broach spring, avoid the damage phenomenon and reduce the cost. The invention simultaneously provide a corresponding using method. The method comprises the specific steps of (1) mounting a steel ball and the spring into an outer circular hole in a shaft sleeve assembly and then placing the steel ball and the spring at the inner side of a spring pressing sheet;(2) pressing the spring pressing plate against the outer wall of the shaft sleeve assembly to fix the spring in the outer circular hole of the shaft sleeve assembly; (3) extending the spring pressingsheet and the shaft sleeve assembly into a cutter sleeve of the device and reach a mounting position; (4) pushing a connecting rod to enable a push plate to push against the shaft sleeve assembly; separating the barrel and the spring pressing sheet from the cutter sleeve; and remaining shaft sleeve assembly in the cutter sleeve so as to finish mounting.

Description

technical field [0001] The invention relates to the technical field of tool holders of horizontal machining centers, in particular to a special device for replacing broach springs and a method for using the same. Background technique [0002] At present, the Yasuda 15T horizontal machining center was installed in 2013. After 3-4 years of use, the tension of the tool pocket in the tool magazine is obviously insufficient, which makes heavy tools often fall out of the tool magazine. Later, it was found that the problem was caused by the broach spring in the tool holder being easily worn out, which can be solved by replacing the spring, but the replacement price of the tool magazine spring is extremely high, and generally all tool holders need to be replaced every 2-3 years. Resulting in extremely high maintenance costs (the cost of accessories alone is greater than 500,000 yuan each time). [0003] Moreover, because the spring is installed inside the tool holder, manual instal...
