Simple drawing force testing device

Abstract

The invention discloses a simple drawing force testing device. The simple drawing force testing device comprises a base, a fixing plate and a tension meter; the fixing plate is fixed to the base, a ball screw is rotationally positioned on the base and sleeved with a ball bearing, the tension meter is fixed to the ball bearing and located above the fixing plate, a positioning column is vertically fixed on the fixing plate, a lower hook is fixedly inserted in the positioning column, an upper hook is fixedly connected under the tension meter, and the upper hook and the lower hook are located on the same straight line. The simple drawing force testing device is simple in structure, small in testing error and accurate in data, and manual drawing is not needed.

Description

technical field [0001] The invention relates to a pulling force testing device, in particular to a simple pulling force testing device. Background technique [0002] Some existing plastic products are usually designed with screw columns, and the pulling force that the screw columns can withstand is an important indicator to ensure product quality. , and then use the hook on the dynamometer to reach the screw column of the product, and then pull it up until the screw column is broken. This test method consumes a lot of physical strength of the staff, and the test is complicated, and this This manual test method has a large error and the data is not accurate enough. [0003] In view of the above-mentioned defects, the designer actively researches and innovates, in order to create a simple pull-out force testing device, which has more industrial value. SUMMARY OF THE INVENTION [0004] In order to solve the above technical problems, the purpose of the present invention is t...

Problems solved by technology

[0002] Some existing plastic products are usually designed with screw posts, and the pull-out force that the screw posts can withstand is an important indicator to ensure product quality. The existing test method is to use a worker to press the pressure block on the product , and then another worker uses the hook on the tension meter to reach the screw column of the column product, and then pulls it up until the screw column is broken. This test method consumes a lot of physical strength of the staff, and the test is complicated, and this This manual test method has large errors and the data is not accurate enough
