Detailed Description

Embodiments of the present invention will be described in detail with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and therefore are only examples, and the protection scope of the present invention is not limited thereby.

Referring to fig. 1 to 3, the present invention provides a stable lifting structure for a spindle, including a guiding mechanism 800 and a spindle 500. Specifically, the method comprises the following steps. The guide mechanism 800 includes guide posts 810, the slide table 300, and rolling bodies 820. The guide column 810 is vertically arranged on the upper surface of the mounting table 100 of the circular cutting machine, the rolling body 820 is mounted on the sliding table 300, and the rolling body 820 rolls along the guide column 810 during the lifting process of the sliding table 300. The main shaft 500 is rotatably mounted on the slide table 300. The stable lifting structure of the main shaft can be used for a circular cutting machine and used for cutting circular objects, such as circular glass or circular iron plates.

In particular implementations, the distance between the centerline of the spindle 500 and the rolling body 820 may be made greater than the length of the tool arm 600. By such an arrangement, the tool arm 600 can be reduced in tolerance, thereby increasing the stability of the spindle 500.

In this embodiment, the sliding table 300 is disposed at the power output end of the lifting driving assembly 200 of the circular cutting machine, the main shaft 500 is disposed at the power output shaft of the rotating driving assembly 400, and the rotating driving assembly 400 is disposed on the sliding table 300. The lifting driving assembly 200 and the rotating driving assembly 400 can be arranged in a staggered mode, and the lifting driving assembly 200, the rotating driving assembly 400 and corresponding parts can be conveniently installed through the staggered arrangement.

When the tool is used, the rolling bodies 820 always abut against the guide columns 810 in the ascending or descending process, so that the ascending and descending of the main shaft 500 can be guided, the left and right swinging of the main shaft 500 in the ascending, descending and rotating processes is further prevented, the left and right swinging of the tool arm 600 is further prevented, and the purpose of improving the cutting quality of a cut product is finally achieved. Meanwhile, the friction between the rolling elements 820 and the guide columns 810 can be reduced by changing the sliding friction into the fixed friction through the rolling elements 820. In other embodiments, the guiding mechanism 800 may also be a column rod, and the side wall of the column rod abuts against the guiding column 810 to also play a guiding role.

In a specific implementation, the rolling elements 820 may be provided in multiple sets, and each set of rolling elements 820 can roll along the guide pillar 810 abutted thereto during the lifting and lowering of the sliding table 300. Stability may be further provided by the simultaneous action of multiple sets of rolling elements 820. Preferably, there are two groups of rolling bodies, there are two guide posts, and the two groups of rolling bodies are respectively abutted with the opposite side walls of the two guide posts. The rolling bodies on the same side are guided, so that the sliding cannot deviate in the lifting process, and the stability is improved.

As a preferred embodiment, the rolling element 820 may be mounted on the sliding table 300 by a mounting rod 830, the mounting rod 830 is a screw, the rolling element 820 is a rolling bearing, and the rolling bearing is screwed with the screw. Adopt antifriction bearing to be rolling element 820, because antifriction bearing is the standard component, have the advantage of conveniently drawing materials and batch production, simultaneously, antifriction bearing and screw rod threaded connection, then adjustable convenient whole antifriction bearing is in the position on the screw rod to control the degree of compressing tightly of antifriction bearing and guide post 810 and the size of contact surface, realize more accurate direction.

In a more preferred embodiment, the mounting rod 830 is further provided with a positioning member 840, the positioning member 840 includes two locking threads, two locking nuts are connected to the threaded rod, and the rolling bearing is clamped and fixed between the two locking threads. Through the clamping fixation of the two locking threads, the rolling bearing can be prevented from displacing in the guiding process, so that the guiding effect is influenced.

Above-mentioned lift structure is stabilized to main shaft, during the use, start circle-cutting machine's lift drive assembly 200 and rotation driving assembly 400, lift drive assembly drives guiding mechanism 800 and main shaft 500 and rises or descend, and simultaneously, rotation driving assembly 400 drive main shaft 500 is rotatory, because at the in-process that rises or descends, antifriction bearing offsets with guide post 810 all the time, then can lead main shaft 500, and then prevent main shaft 500 at the lift and rotate in-process horizontal hunting, thereby improve main shaft 500 and cutter arm 600's stability, finally realize improving the purpose of the cutting quality of cutting product.

In addition, the rolling bearing changes sliding friction into fixed friction, so that the friction between the rolling bearing and the guide column 810 can be reduced; through the clamping fixation of the two locking threads, the rolling bearing is prevented from displacing in the guiding engineering, so that the guiding effect is influenced.
