Description

TECHNICAL FIELD

[0001] The utility model relates to stator processing equipment field, especially a kind of quick-release vertical rod for stator positioning. BACKGROUND

[0002] In the processing of stator, such as glue dispensing, welding and the like steps, its positioning is generally carried out by mandrel. However, the positioning mandrel of the existing stator is generally fixed to the clamping shaft by screw rod. This design has the following disadvantages:

[0003] 1. The screw rod is troublesome to screw, especially for automated equipment. When the number is large, it takes a long time, which affects the overall assembly efficiency.

[0004] 2. It is also troublesome to disassemble or replace, and there is a certain error (deviation of locking degree of thread) and wear;

[0005] 3. The existing stator generally uses a single limiting structure, so there is a certain probability of falling during inverted transportation, which affects the stability of automated production. SUMMARY

[0006] The main purpose of the utility model is to provide a quick-release vertical rod for stator positioning, which improves the existing mandrel structure to make it easy to install and accurately positioned and stably clamped.

[0007] To achieve the above-mentioned purpose, the utility model provides a quick-release vertical rod for stator positioning, comprising,

[0008] A clamping shaft is provided with an insertion hole in the middle part. A through hole is provided in the side wall of the insertion hole. A plurality of balls are distributed along the peripheral wall of the through hole. The hole diameter of the inner side wall of the through hole is smaller than the hole diameter of the ball.

[0009] A locking sleeve is slidably mounted on the outer wall of the clamping shaft and can drive the ball part to move between the position where it is clamped into the insertion hole and the position where it is away from the insertion hole.

[0010] A mandrel is provided with an insertion rod in the lower part, which is matched with the insertion hole. The insertion rod is provided with a positioning groove matched with the ball.

[0011] In actual design, the clamping shaft is provided in a predetermined mechanism to facilitate its processing and use. When the mandrel needs to be installed, the insertion rod part of the mandrel is inserted into the position of the insertion hole. When the positioning groove of the insertion rod moves to the position of the ball, the ball is clamped into the positioning groove, thereby achieving the fixation of the mandrel.

[0012] When unlocking is needed, the locking sleeve is away from the ball, and at this time the ball can exit the positioning groove, thereby achieving the unlocking of the mandrel.

[0013] The installation mode is simple in structure, and convenient to disassemble and replace. BRIEF DESCRIPTION OF DRAWINGS
