Description
Technical field
The present invention relates to a kind of seat rotation and the reciprocal abrasion tester of castor, be mainly used in the exercise performance of rotary seat is detected.
Background technology
Chair is in use that seat face and castor move simultaneously, separately seat face or castor is carried out wear test real situation when not reflecting chair work.When castor is tested in addition, the castor protections such as wheel flies out item in pressure and to-and-fro movement is not done the injury that easily causes personnel.The experiment of existing mode office chair foot wheel abrasion, a wear test to castor; The rotation durability experiment is only to the rotation durability experiment; Traditional mode is adopted in motion.The shortcoming that exists is:
1, Legs of office chair wear test: only to the castor wear test of chair, in use castor and seat surface are worked simultaneously often because of chair can not comprehensively to reflect chair situation in use.
2, rotation durability experiment: only the permanance of seat surface rotation is done experiment, can not simulate chair and in use rotate the motion of also using castor.
3, mode of motion: the wearing and tearing that mode of motion adopts these modes such as traditional common rail or line slideway to be in operation are large, and driving force is required to be prone to the phenomenon that card is agree in motion process greatly, safeguard more loaded down with trivial details.
4, Legs of office chair wear test, rotation durability experiment: if want to detect all round properties of the chair invisible like this increase of two equipment must have been arranged cost, every machine can only be done a kind of experiment, and it is just very long that experiment can not carry out detecting like this time of same product simultaneously.Finish that a detection is artificial again is transformed into that to do the such efficient of experiment on an other equipment just lower.
When 5, outer castor is tested, the castor protections such as wheel flies out item in pressure and to-and-fro movement is not done the injury that easily causes personnel.
Summary of the invention
The present invention aims to provide the rotation of a kind of seat and the reciprocal abrasion tester of castor, with solve that prior art exists can not be simultaneously to seat surface rotation permanance and the castor wear test of swivel chair; And the wearing and tearing of experimental provision in experimentation are large, driving force required large, are prone to card and gnaw phenomenon, safeguard more loaded down with trivial details, ineffective problem.
Technical scheme of the present invention is: a kind of seat rotation and the reciprocal abrasion tester of castor, it is characterized in that, comprise that platform, gantry, gantry drive cylinder, pressurized cylinder, air motor and rotary body, two lower ends at gantry are slidably mounted on the guide rail on platform both sides, gantry is installed between platform and gantry drives cylinder; Pressurized cylinder is installed on the top at gantry, and the bottom of the piston rod of this pressurized cylinder lower end is connected with the rotating shaft of air motor; The top of rotary body is rotatably connected on this piston rod, and the eccentric part of this rotary body bottom is rotationally connected a manometric head, and the bottom of described air motor and the bottom of this rotary body are fixed; Be provided with the swivel chair stationary installation in the bottom at this gantry.
Advantage of the present invention is: simple to operation, save cost, performance is more stable, Interventions Requested more comprehensively, overall appearance is strong, safe, efficient is high, tests on an equal basis detection time short, safe.
