Embodiment Construction

[0022] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0023] like Figure 1 to Figure 3 As shown, the guide sleeve with displacement sensor of the present invention includes a guide sleeve base 2, a guide sleeve upper cover 3, a guide wheel assembly 5, a displacement testing mechanism 100, and the like.

[0024] Two groups of guide wheel assemblies 5 are respectively installed before and after the guide rod 1 passes both sides of the guide sleeve base 2 , and the guide wheels in the guide wheel assembly 5 are in rolling contact with the guide rod 1 . On both sides of the guide sleeve base 2, two sets of displacement testing mechanisms 100 are respectively installed in the middle of the two guiding wheel assemblies 5, and the rubber sleeve 11 of the displacement testing mechanism 10 is connected with the guide rod 1 by rolling friction, and the upper end of the displacement testing mechanism 100 passes The...

Abstract

The invention relates to a guide sleeve with a displacement sensor, which comprises a guide sleeve base, an upper cover of the guide sleeve and guide wheel assemblies, wherein the front and the back of two sides of a cooperated position of the guide sleeve base and a guide rod are respectively provided with two groups of guide wheel assemblies. The guide sleeve with the displacement sensor is characterized in that two sides of the guide sleeve base and the middles of the two guide wheel assemblies are respectively provided with a displacement test mechanism; the rubber sleeves of the displacement test mechanisms are in rolling friction connection with the guide rod; and the upper end of each displacement test mechanism is fixed on the guide sleeve base by the upper cover of the guide sleeve. The linear displacement of the guide rod is changed into a rotation corner by the displacement test mechanisms, and a displacement test is realized by an encoder or a similar sending element. Therefore, according to the guide sleeve with the displacement sensor, which is disclosed by the invention, guidance, additional load support and the displacement test are combined together to omit an additional connection mechanism for the displacement test.

Description

technical field [0001] The invention relates to a guide sleeve in a mechanical guide mechanism, in particular to a guide sleeve with displacement testing function. Background technique [0002] The common guide mechanism in the mechanical structure is composed of a guide rod and a guide sleeve, and its function is only to guide the movement of the guide rod and bear the corresponding non-working additional load. For example, in auxiliary guide mechanisms such as hydraulic cylinders, its function is only for guiding the movement of the guide rod and bearing the non-working additional load of the piston rod. The displacement of the piston rod of the oil cylinder often needs another displacement sensor to test. However, the existing mechanical guide sleeve cannot test the displacement of the piston rod of the oil cylinder. Contents of the invention [0003] The present invention provides a guide sleeve with a displacement sensor, which combines guidance, additional load sup...
