Description
Technical Field
The utility model belongs to the technical field of anchor clamps, especially, relate to a transmission shaft dynamic balance anchor clamps.
Background
When the transmission shaft used on the automobile is used for dynamic balance detection in a production workshop, the end part of the transmission shaft is installed on a balancing machine through a bolt and a nut, the installation and the disassembly are troublesome, the production efficiency is low, errors are easy to occur in positioning, the dynamic balance precision is low, and the stability is poor.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to provide a transmission shaft dynamic balance anchor clamps that simple to use, location are accurate, dynamic balance precision is high, stability is strong.
In order to solve the technical problem, the utility model discloses a technical scheme does: the on-line screen storage device comprises a base, the bottom of base is provided with the positioning disk, be equipped with locating hole and blind hole on the positioning disk, base upper portion outer wall is provided with the external screw thread, the center of base is first through-hole, first through-hole upper portion is provided with first boss, be provided with the elastic sleeve above the first boss, the center of elastic sleeve is the second through-hole, second through-hole upper portion is provided with the second boss, the elastic sleeve top is provided with the round shell fragment, be equipped with the gap between adjacent shell fragment, base upper portion is connected with the lock nut, lock nut lower part inner wall be provided with external screw thread assorted internal thread, lock nut upper portion inner wall be provided with shell fragment assorted clamping ring.
The additional technical characteristics are as follows: the outer wall of the lock nut is provided with a lock hole;
the elastic sleeve is fixed with the base through a positioning pin.
The utility model provides a during transmission shaft dynamic balance anchor clamps used, pass the locating hole on the positioning disk with the bolt and twist the screw on the balance machine, with pedestal mounting on the balance machine, anticlockwise unscrew the lock mother, make the round shell fragment extend, gap grow between adjacent shell fragment. Then insert the elastic sleeve with the tip of transmission shaft, the tip of transmission shaft and the contact of second boss, screw up the lock mother clockwise, because the clamping ring inner wall is thin frustum form from top to bottom, the clamping ring makes round shell fragment shrink, and the gap between adjacent shell fragment diminishes, locks the tip of transmission shaft, then action balance detects. The outer wall of the lock nut is provided with a lock hole, and the lock nut is unscrewed and screwed by using a hook head wrench matched with the lock hole, so that the lock nut is convenient and fast to screw. The elastic sleeve is fixed with the base through the positioning pin, so that the elastic sleeve is positioned, and the elastic sleeve is prevented from being dislocated. The utility model provides a transmission shaft dynamic balance anchor clamps is simple to use, the location is accurate, dynamic balance precision is high, stability is strong.
