Description

Technical Field

[0001] The utility model relates to the technical field of seat detection equipment, in particular to a five-claw seat foot compression testing machine. Background Art

[0002] The five-claw chair foot is installed at the bottom of the seat or swivel seat to play a supporting role. After the product is produced, its compressive performance needs to be tested to detect whether it can withstand the specified pressure. In the past, a certain weight was usually added to the seat foot above the five-claw chair foot for testing. However, since the pressure value to be tested is usually 80-100KG, it is necessary to carry the weight of the corresponding weight to the top of the five-claw chair foot. The weight is heavy and the labor intensity is high. In addition, it needs to be placed gently, otherwise it will apply greater pressure to the product, causing product damage, affecting the detection accuracy, and low safety. Utility Model Content

[0009] Further description of the utility model, the lifting drive device includes a reduction motor, a driving wheel, a driven wheel, a tensioning wheel, a synchronous belt, two screw rods and two guide rods; the two screw rods are arranged on the left and right sides of the carrier and are rotatably connected to the machine base; the screw rod is connected to the lifting slider through a nut; the two guide rods are respectively located on the outside of the two screw rods and are slidably connected to the lifting slider; the driving wheel and the driven wheel are respectively installed at the lower ends of the two screw rods; the tensioning wheel is rotatably connected in the machine base and is located between the driving wheel and the driven wheel; the synchronous belt transmission is connected between the driving wheel, the driven wheel and the tensioning wheel; the reduction motor is installed in the chassis and the power output end is connected to the driving wheel.

[0010] The beneficial effects of the utility model are:

[0011] This design places the five-claw chair foot on a carrier and a weight on top of the five-claw chair foot so that the weight is located directly below the pressure head. The pressure head is then controlled to move downward and pressed above the weight through the lifting drive device. The pressure sensor detects the pressure value in real time and stops when the set pressure value is reached to observe whether the five-claw chair foot can withstand the pressure. This setting is easy to operate and has high stability. The setting of the weight can not only pre-press the five-claw chair foot, but also the force point of the five-claw chair foot during the detection process is the contact surface with the weight, which can simulate the force surface of the actual assembly effect, and the detection effect is better.
