Chair frame detection device and method

Abstract

The invention discloses a chair frame detection device and method, and the device comprises a detection bottom plate, the top of the detection bottom plate is fixedly provided with a detection frame, one side of the detection frame is rotatably connected with a rotating shaft assembly, one side of the top of the detection bottom plate is provided with a power assembly which drives the rotating shaft assembly to rotate, and the rotating shaft assembly comprises an optical axis and a screw rod; the top end of the optical shaft is fixedly connected with the bottom end of a lead screw, and the lead screw is in threaded connection with a lead screw nut. According to the office chair stability detection device, the power assembly, the vertical detection assembly and the horizontal detection assembly are arranged to be used in cooperation, stability detection can be conducted on the office chair in the vertical direction and the horizontal direction, due to the fact that the acting force of a motor is stable, the screw rod is matched with the screw rod nut, the structure is reasonable, the detection data is standardized, the detection efficiency is high, the accuracy is high, the detection quality is stable, and the phenomena of unstable air pressure, large error and low accuracy of an air cylinder caused by the use of the air cylinder for detection are avoided.

Description

technical field [0001] The invention belongs to the technical field of office chairs, and in particular relates to a chair frame detection device and a detection method. Background technique [0002] Office chairs refer to various chairs equipped for the convenience of work in daily work and social activities. Office partners divide office chairs into narrow and broad senses. Office chairs in the narrow sense refer to the back chairs that people sit on when they work on the desktop in a sitting position. Office chairs in the general sense refer to all chairs used in the office, including executive chairs, middle shift Chairs, meeting chairs, staff chairs, meeting chairs, visitor chairs, training chairs, etc. [0003] At present, in the field of office chair production and manufacturing, the stability of the chair needs to be tested after the components of the chair are assembled in a simple production line.

Problems solved by technology

[0003] At present, in the field of office chair production and manufacturing, the stability of the chair needs to be tested after the components of the chair are assembled in a simple production line. The existing testers often test the stability of the chair at a simple testing station. , to see if the chair is stable and whether there is any abnormal sound. This kind of detection method is inefficient, and the human factors are relatively large. It cannot be standardized and cannot be tested according to the strength of the industry standard. Therefore, it often causes large fluctuations in product quality.

[0004] As for the other testing method using a cylinder, this type of test equipment can only apply a loading force to the specimen in the vertical direction, and cannot provide a loading force in the horizontal direction. According to the standard, multiple types of chairs The stability test of stool furniture needs to apply a horizontal loading force to complete the test, and the air pressure of the cylinder is often unstable, the error is large, the accuracy is not high, the stability of the test data is poor, and the operation is also difficult. very inconvenient
