Description

Technical Field

[0001] The utility model relates to the technical field of caster bracket detection equipment, in particular to an external dimension detection equipment used for a caster bracket. Background Art

[0002] Casters include movable casters and fixed casters. Movable casters are what we call universal wheels, and their structure allows 360-degree rotation; fixed casters are also called fixed casters, which have no rotating structure and cannot turn. Universal casters are widely used in medical equipment, industrial equipment, furniture and other technical fields due to their light operation and flexible steering characteristics.

[0003] like Figure 1 As shown, a universal caster includes a bracket A, a fixing plate B capable of horizontal rotation is installed on the upper end of the bracket A, a roller C is rotatably installed on the inner side of the lower end of the bracket A, and two ear plates D extending to one side of the upper end of the bracket A are correspondingly provided on the upper end of the bracket A, and a brake spring F located at the lower side and a brake pedal E located at the upper side are hingedly installed on the inner side of the two ear plates D. Figure 2 A caster bracket A shown in the figure comprises a horizontal top plate A-1, wherein the center of the horizontal top plate A-1 is provided with a mounting hole A-2 penetrating the plate body, the upper end of the mounting hole A-2 is provided with a countersunk step groove A-2a recessed inwardly therefrom, and the left and right end edges of the horizontal top plate A-1 are respectively provided with an arm plate A-3 extending downward, and the lower ends of the two arm plates A-3 are respectively provided with mounting holes A-3a penetrating the plate body. Since the caster bracket plays an important supporting role between the mobile device and the caster, strict requirements are imposed on the outer structure, dimensional accuracy and concentricity of the mounting holes A-2 on the two arm plates of the caster bracket.

[0004] After the caster bracket is processed, tools such as height gauges and calipers are usually used to manually inspect the outer structure, dimensional accuracy, and concentricity parameters of the mounting holes 2 on the two arm plates of the caster bracket to determine its qualification. The problems of this scheme of manually inspecting the qualification of the caster bracket are: (1) it is greatly affected by human factors, and it is difficult to ensure the reliability of the qualified inspection results of each caster bracket; (2) there are many inspection data involved in the inspection, and many inspection tools are used, which leads to high labor intensity of the inspection personnel, high labor costs, and low inspection efficiency, which seriously restricts the inspection efficiency of the caster bracket. To this end, the utility model proposes an outer dimension inspection device for the caster bracket, in order to solve the above technical problems. Summary of the invention
