Problems solved by technology
However, because the cooperation between the inner taper sleeve and the collet is manually driven by direct manual rotation, the locking connection between the inner taper sleeve and the straight glass rod is unstable, and sometimes there will be slipping between the two

The invention relates to the technical field of main shaft locking devices, and discloses a straight glass rod main shaft locking structure. The straight glass rod main shaft locking structure comprises an inner taper sleeve arranged on a straight glass rod in a sleeving mode, a spring chuck located between the inner taper sleeve and the straight glass rod, a locking nut in threaded connection with the inner taper sleeve and a clamping and fixing device limiting rotation and movement of the inner taper sleeve. The chuck end of the spring chuck is defined as a front end, and the cylindrical end of the spring chuck is defined as a rear end. The rear end of the spring chuck extends out of the inner taper sleeve. The inner diameter of the inner taper sleeve is gradually increased from the front end to the rear end, and an external thread is arranged on the outer side wall of the rear end of the inner taper sleeve. The front end of the locking nut is provided with an open groove, the groove wall of the open groove is provided with an internal thread matched with the external thread, and the groove bottom of the open groove correspondingly abuts against the rear end of the spring chuck. By means of the mode, locking connection between the inner taper sleeve and the straight glass rod can be guaranteed, and operation is easy, convenient and easy.
Description
technical field [0001] The invention relates to the technical field of spindle locking devices, in particular to a spindle locking structure for straight glass rods. Background technique [0002] Some existing equipment needs to use straight glass rods, and it is necessary to connect the straight glass rods with other components through a gear transmission to achieve the purpose of controlling the rotation of the straight glass rods. Due to the special structure of the straight glass rod, the connecting gear in the gear transmission cannot be directly fixedly connected with the straight glass rod. In this regard, the straight glass rod is usually locked by a combination of an inner tapered sleeve and a collet, and then the connecting gear in the gear transmission is fixed on the inner tapered sleeve to realize the connection gear in the gear transmission. Fixed connection to straight glass rods. However, since the cooperation between the inner taper sleeve and the collet i...
