摘要： Disclosed herein is an apparatus for grinding a compression line spring. The apparatus includes a lower chain conveyor (100), an upper chain conveyor (200), and grinding units (300). The lower chain conveyor includes chain units each having first support blocks (115) for supporting compression line springs. The upper chain conveyor includes chain units each having second support blocks (215) for compressing downward upper portions of the compression line springs and thus supporting the compression line springs. The grinding units grind seat surfaces formed on opposite ends of the compression line springs that are moved by the upper and lower chain conveyors. A V-shaped depression (115a) is formed in each first support block so that each of the compression line springs is seated onto the corresponding V-shaped depression. A lower surface (215a) of the second support block that compresses the compression line springs has a planar structure.

摘要： A large number of unit carriers are fed by an endless chain into a horizontal passageway within the grinding machine in a state each having a coil spring as a workpiece received thereon. Before reaching the position of a grinding wheel disposed at one side of the passageway, the coil spring on each carrier is clamped thereto by a clamping lever provided thereon. For the purpose of swinging the clamping lever up to a clamping position, an urging bar to be engaged therewith is disposed along the passageway above the same in a state carried into the movement locus of the clamping lever.

摘要： Disclosed is a method for grinding a spring with high quality and high efficiency, comprising the steps as follows: firstly, at least one of an upper grinding wheel (1) and a lower grinding wheel (2) is configured to comprise an inner grinding wheel (21) and an outer grinding wheel (24), wherein the inner grinding wheel (21) is fitted in the outer grinding wheel (24); the inner grinding wheel (21) or the outer grinding wheel (24) is driven by a transmission mechanism, the inner grinding wheel (21) and the outer grinding wheel (24) rotating in opposite directions; after a complete spring is fed to a space between the upper grinding wheel (1) and the lower grinding wheel (2), the complete spring is moved back and forth in the plane of the grinding wheels; and then the upper grinding wheel (1) is moved downwardly such that two end faces of the spring are ground by the grinding wheels, and when the height of the ground spring meets the requirement, the upper grinding wheel (1) is stopped moving downwardly and is returned to the original point later. Then, the ground spring movement is stopped and it is moved away from the space between the two grinding wheels, i.e., the complete spring is removed. In this way, the spring is ground in a revolving state, which can improve the yield and quality of ground springs, save energy and protect the environment, and result in a low cost of grinding, a simple structure, low cost for manufacturing parts, long persistence in precision of mechanisms, and good stability.

摘要： A method of grinding spring ends of helical compression springs is carried out using a numerically controlled spring end grinding machine having a grinding unit, a loading unit and a control unit that controls the loading unit and the grinding unit. The grinding unit has a pair of grinding wheels including two rotatable grinding wheels between which is formed a grinding space. The loading unit has at least one loading plate substantially rotatable axially parallel to the grinding wheels and has a plurality of out-of-axis spring receptacles, each to receive a helical compression spring.

摘要： A first end surface of a coiled compression spring at its relaxed length is machined to a plane transverse to the spring axis. The spring is then placed in a press structure having first and second opposed planar support surfaces, with the machined spring end surface bearing against the first support surface, the unmachined spring end surface bearing against a planar first surface of a lateral force compensation member, and an opposite, generally spherically curved surface of the compensation member bearing against the second press structure support surface. The spring is then compressed generally to its loaded length, and a circumferentially spaced series of marks, lying in a plane parallel to the second press structure support surface, are formed on the spring coil on which the second spring end surface lies. The spring is then removed from the press structure, and the second spring end surface is machined to the mark plane. When the spring is subsequently compressed to its loaded length the precisely parallel relationship between the machined spring end surfaces substantially eliminates undesirable lateral deflection of the spring.
