Problems solved by technology

At present, the instrument specially used to test the spring force value of the wave-shaped washer on the market is about 100,000 yuan. Every time the fixture is changed, it needs to be adjusted by an expert. Both the adjustment cost and the purchase cost are high. And limited by the two guide rods on the instrument, the size and shape of the spring to be tested are limited, and the wave-shaped washer springs of different sizes cannot be replaced and measured at will, which cannot meet the actual needs of existing production

Abstract

The invention discloses a wavy gasket spring elasticity detecting device and method. The detecting device comprises a fixing sleeve (3) and a base (2), and is characterized in that the upper end of a support (1) is connected with the base (2), the fixing sleeve (3) is arranged at the lower portion of a through hole (6) formed in the base (2), the fixing sleeve (3) is provided with an inner hole (9) and an adjusting hole (8), the inner hole (9) is a through hole in the axis direction, the adjusting hole (8) is perpendicular to the axis direction and penetrates through the fixing sleeve (3) to be communicated with the inner hole (9), the axis of the through hole (6) and the axis of the inner hole (9) coincide, a measuring rod (12) of a dial indicator (10) penetrates through the inner hole (9) and the through hole (6), a measuring head (5) of the dial indicator (10) makes contact with the lower surface of a pressing plate (4), and an adjusting screw (7) is arranged in the adjusting hole (8). The detecting method is simple, feasible, economical, practical and reliable in operation.

Description

technical field [0001] The invention belongs to the technical field of spring force detection, and in particular relates to a wave-shaped washer spring force detection device and a detection method thereof. Background technique [0002] As a widely used fastener, spring has a special structure in some special occasions. Wave-shaped washer spring is a kind of washer spring with wave shape, that is, it looks like a washer in front view and a wave in side view. [0003] The measurement of the spring force of the wave-shaped washer usually requires special testing instruments. At present, the instrument specially used to test the spring force value of the wave-shaped washer on the market is about 100,000 yuan. Every time the fixture is changed, it needs to be adjusted by an expert. Both the adjustment cost and the purchase cost are high. And limited by the two guide rods on the instrument, the size and shape of the spring to be tested are limited, and it is impossible to repla...
