Description
Technical Field
The invention relates to the technical field of spring cutting machine tools, in particular to a spring grinding mechanism.
Background
The traditional large-wire-diameter spring grinding equipment generally comprises a guide rail type spring grinding machine and a pendulum type spring grinding machine, wherein the guide rail type spring grinding machine and the pendulum type spring grinding machine both adopt a grinding wheel, a grinding wheel spindle is horizontally arranged, and the basic principle schematic diagrams of the guide rail type spring grinding machine and the pendulum type spring grinding machine are shown in figures 1 and 2.
Referring to fig. 1, the guide rail type spring grinding machine works according to the following principle: the spring is placed on the V-shaped groove of the V-shaped block, and the spring is clamped by a mechanical device so as to be fixed in the V-shaped groove. When grinding is needed, the V-shaped block moves linearly left and right under the drive of the mechanical mechanism, namely the spring moves linearly back and forth between A, B points, meanwhile, the plane of the rotary grinding wheel is driven by the mechanical mechanism to feed to the grinding end face of the spring slowly, and cooling liquid is needed to be added to the grinding position for cooling. In the process, the end face of the spring is ground, after the size of the grinding spring meets the set requirement, the grinding wheel automatically returns to the starting position, meanwhile, the spring stops moving linearly left and right, the mechanical device is loosened by manually operating the switch and is manually taken out, and the working process of grinding the end face of the spring is completed. If the other end face of the spring needs to be ground, the process is repeated.
Referring to fig. 2, the pendulum type spring grinding machine is an improvement on the guide rail type spring grinding machine, and mainly changes the original linear guide rail pair mechanism into a crank rocker mechanism, namely, the spring reciprocates linearly between A, B points and changes into reciprocating circular motion. The grinding device mainly solves the problems that the flatness of a ground spring and the perpendicularity of an end face to an axis are difficult to guarantee due to the fact that a working guide rail is easy to wear and cannot be compensated due to the fact that the working environment of the ground spring is severe, and the grinding working principle is not substantially changed.
It is worth mentioning that the springs do not rotate when the two large-wire-diameter spring grinding machines grind. Therefore, there are the following disadvantages:
firstly, the grinding precision is low: (1) the flatness precision of the grinding spring end face is low: because the design concept of the spring grinding machine is too ideal, the grinding flatness precision is completely realized by the grinding flatness precision of the grinding wheel. In the grinding process of a grinding plane of a grinding wheel, the grinding linear speed and the grinding time of each abrasive particle are not different and greatly different, such as: the grinding linear speed of the abrasive particles close to the inner circle and the outer circle of the grinding wheel is greatly different, the abrasive particles close to the inner circle of the grinding wheel only move to the middle of A, B points to participate in grinding; abrasive particles close to the excircle of the grinding wheel only move to A, B two points to participate in grinding; the abrasive particles near the middle diameter of the grinding wheel plane and the spring take part in grinding in the whole motion process of A, B points. Therefore, the abrasion of the grinding plane of the grinding wheel is not uniform, namely the stability time of the grinding flatness precision of the grinding wheel is short, and the grinding wheel can only adapt to a spring with low grinding precision. (2) The verticality precision of the grinding spring is low: the spring grinding machine is designed in such a way that after the spring is arranged on the V-shaped block, the grinding verticality precision can be ensured as long as the central line of the spring is perpendicular to the grinding surface of the grinding wheel. That is to say, the accuracy instability of the planeness of the grinding surface of the grinding wheel is not considered, and the verticality accuracy of the grinding spring is influenced. (3) The parallelism precision of two end surfaces of the grinding spring is low: because the design idea of the spring grinding machine is as follows: the two end faces of the spring are not ground at one time, the large-wire-diameter spring is basically formed by hot rolling, and the outer diameter of a spring rolling core rod needs to be slightly tapered, namely the outer diameter of the rolled spring is slightly tapered. And the spring is subjected to oil quenching before being ground, and part of the spring is bent to some extent. In short, the outer diameter of the spring is less consistent. The two end faces of the spring are respectively ground by using different outer diameter parts of the spring as references, and obviously, the parallelism precision of the two end faces of the spring is low. (4) The grinding precision is low under the spring deformation state: because the spring is a flexible member, i.e. the spring is to be deformed under the clamping of the mechanical device, i.e. the spring is ground in a deformed state, after grinding, the mechanical device is released and the spring deformation is restored. The grinding spring accuracy is low.
Secondly, production efficiency is low, and intensity of labour is big: the spring grinding machine not only needs to clamp the spring by a worker each time, but also can grind one end face of one or two springs once, obviously, the grinding production efficiency is low, and the labor intensity is high.
Thirdly, the ground surface is easy to be burnt and has large energy consumption: the large-wire-diameter spring grinding machine is mainly characterized by large grinding area, large generated heat, poor heat dissipation and easy scorching of the ground surface. The spring grinding machine is not burnt in order to grind the surface, and a large amount of cooling liquid is added to cool the grinding part, so that a large amount of energy is wasted.
