Problems solved by technology

The existing testing machine is powered by compressed air, and the piston rod of the cylinder is used to push the impact head up. According to the drop height determined by the compressible amount measured before the experiment, the impact head is applied to the specified part of the mattress at the same frequency. , do a free fall, and repeat the specified number of times of loading, but because the compressibility needs to be measured manually before the experiment, and it needs to be converted into the drop height of the impact head, the operation is time-consuming and laborious, and more pneumatic components are used, the system complex, poor reliability

specific Embodiment approach

[0008] refer to figure 1 , a mattress durability testing machine, a steel structure beam 2 is erected on the detection platform 1, and a loading device is fixed on the beam. In the loading device, an impact guide rod 5 is connected to the beam 2 by a guide rod support sleeve 6. The guide rod 5 is connected to the connecting rod 7, and the connecting rod 7 is connected to the motor 11 through the eccentric wheel 8, the coupling 9, and the reduction box 10. The loading frequency of the loading head 3 is controlled by adjusting the working speed of the motor 11. After starting the motor 11 , the eccentric wheel 8 runs, drives the impact guide rod 5, and then drives the loading head 3 to reciprocate up and down. After reaching the specified loading times, turn off the motor and perform subsequent detection work. The height of the loading head's up and down movement is determined by the radius of the eccentric wheel.

Abstract

A testing machine for mattress durability comprises a test platform, a beam, a loading device, and a pounding head. The steel-structure beam stands on the test platform; and the loading device is fixed on the beam. The testing machine is characterized in that in the loading device, a pounding guide rod is connected to the beam through a guide rod support sleeve, the pounding guide rod can move up and down and is connected with a connection rod, and the connection rod is connected to a motor through an eccentric wheel, a coupling and a reduction gear box. The invention replaces the prior pneumatic logic valve control system; the height of the upward and downward movement is determined by the radius of the eccentric wheel; and the invention has the advantages of simple structure, convenient operation and high work efficiency, and improves the measure precision.

Description

technical field [0001] The invention relates to a testing machine for testing the durability of a mattress, which belongs to the technical field of product testing and experimentation. Background technique [0002] According to industry standards, mattresses for upholstered furniture need to undergo durability tests to simulate the fatigue resistance of upholstered furniture under normal and abnormal use. The existing testing machine is powered by compressed air, and the piston rod of the cylinder is used to push the impact head up. According to the drop height determined by the compressible amount measured before the experiment, the impact head is applied to the specified part of the mattress at the same frequency. , do a free fall, and repeat the specified number of times of loading, but because the compressibility needs to be measured manually before the experiment, and it needs to be converted into the drop height of the impact head, the operation is time-consuming and l...
