Embodiment Construction

[0032] Now illustrate structural features of the present invention in conjunction with accompanying drawing:

[0033] The present invention includes a casing 10 and a slider brush assembly 20. The side casings located in the length direction of the casing 10 and arranged oppositely are composed of a corrugated plate body 11, and the outer surface of the corrugated plate body 11 is perpendicular to the casing 10. The section in the longitudinal direction is wave-shaped, and the housing 10 is provided with a guide groove 12 on the wave-shaped plate body 11 for the slider brush assembly 20 to move along the length direction of the housing 10 . The casing 10 is made of aluminum alloy, and the surface is plated with a layer of anodized aluminum, so as to prevent the casing of the product from being corroded and improve the service life of the product. In the present invention, the side casing of the casing 10 is creatively arranged in a corrugated structure, that is, the side panel...

Abstract

The invention relates to a slide block type linear displacement sensor. The sensor comprises a housing and a slide block brush assembly. A side face housing which is arranged in the length direction of the housing and opposite to the housing is formed by a wave-shaped plate body. The cross section, which is perpendicular to the length direction of the housing, of outer side plate face of the wave-shaped plate body is wave-shaped. Slide grooves which are arranged in the wave-shaped plate body and through which the slide block brush assembly moves along the length direction of the housing are arranged in the housing. The wave-shaped plate body has good anti-deformation ability, so defects of too big linear errors and deformation in processing caused by the fact that the housing is too long can be avoided; assembly precision of the product is greatly improved; reliability of product in long stroke is ensured; smooth cooperation degree between the oppositely arranged guide grooves in the wave-shaped plate body in the housing and a slide sleeve in the slide block brush assembly is increased; and product quality and measurement precision can be further improved.

Description

technical field [0001] The invention relates to the field of displacement sensors, in particular to a slider type linear displacement sensor. Background technique [0002] Displacement sensors are widely used in woodworking machinery, special machinery for injection molding machines, special machinery for blister machines, printing machinery, medical equipment, robot position control, engineering monitoring computer-controlled motion machinery systems, and other occasions that require accurate displacement measurement. The linear displacement sensor is based on the sliding rheostat principle, which converts the mechanical displacement into an electrical signal. The sliding rheostat changes the resistance value through the displacement of the slider on the slide rail. The two ends of the sliding rheostat are connected to a DC voltage, allowing a small micro-ampere current to pass. The voltage between the slider and the starting end is the same as the slider. proportional to ...
