Teaching device for demonstrating all form and location tolerance detection methods

Abstract

The invention provides a teaching device for demonstrating all form and location tolerance detection methods. One end of each dual-end left-right rotary bolt is connected with a reference platform; the other ends of the dual-end left-right rotary bolts are screwed with bases having screw holes; a screw rod in a lower layer is provided with screw nuts; two ends of the screw rod are fixed to bearing seats; one end of the screw rod is provided with a scale turn button; two linear guide rails parallel to the screw rod and the bearing seats are fixed on a lower pedestal; the lower pedestal is fixedly connected with the reference platform; mounting structures in a middle layer and an upper layer are the same with that of the lower layer; a dual-tip bottom plate is fixed on the reference platform and is provided with two linear guide rails, wherein the linear guide rails are provided with a fixed tail seat, a slide seat and an adjustable tail seat; a revolving body workpiece can be clamped by the tips of the fixed tail seat and the adjustable tail seat; one dual-end left-right rotary bolt is screwed on the base having the screw hole, and the height of one end of a reference block can be adjusted through one end of the dual-end left-right rotary bolt, and therefore, the reference surface of the reference block can be positioned in a needed angle; and in usage, a groove-type slide block, a layout pedestal and the revolving body workpiece are fixedly installed, so that all form and location tolerance detection methods can be demonstrated.

Description

technical field [0001] The invention relates to a teaching device for demonstrating all detection methods of shape and position tolerances, in particular to a teaching device for demonstrating all detection methods of shape and position tolerances. Background technique [0002] According to the survey of teachers, students and practice training bases of mechanical professional courses, it is found that the teaching equipment and instruments of the course "Tolerance Fitting and Measurement Technology" are expensive, require high operating conditions, have limited functions, and are inconvenient to carry. They can only demonstrate part The measurement method of shape and position tolerance does not meet the actual needs of teaching, and it is not economical and practical. Contents of the invention [0003] The object of the present invention is to provide a teaching device for demonstrating all shape tolerance detection methods, which can easily assist teachers in demonstrat...
