Automatic efficient drawing force testing device

Abstract

The invention discloses an automatic efficient drawing force testing device, which comprises a workbench, a fixed rod, a cross beam, a sliding block, a locating block, a lifting air cylinder, a compaction air cylinder and a tensiometer. The fixed rod is vertically fixed on the workbench and is in the shape of inverted L. The cross beam moves to the left and right and is connected to a horizontal part of the L shaped fixed rod. The sliding block slides back and forth and is horizontally connected to one side of the cross beam. The lifting air cylinder is vertically fixed at the lower end of the sliding block, the tensiometer is vertically fixed at the head of the lifting air cylinder, the lower end of the tensiometer is fixedly connected to a hook, the workbench is horizontally equipped with a ball screw, and a ball bearing moving left and right is sleeved on the ball screw. The device also includes a support frame. The support frame is vertically fixed on the ball bearing, the compaction air cylinder moves up and down and slides back and forth to be connected to the support frame, the compaction air cylinder is disposed vertically, and a pressing block is fixed at the head of the compaction air cylinder.

Description

technical field [0001] The invention relates to a pull-out force test device, in particular to an automatic high-efficiency pull-out force test device. Background technique [0002] Some existing plastic products are usually designed with a boss column, and the pull-out force that the boss column can withstand is an important indicator to ensure product quality. , and then another worker uses the hook on the tension meter to reach the boss column of the column product, and then pulls it up until the boss 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. [0003] Moreover, the position of the tension gauge of the existing pull-out force testing device is fixed, and the operation is very inflexible. [0004] At the same time, the existing pull-out force testing device usually presses the plastic product manually to prevent the...

[0002] Some existing plastic products are usually designed with a boss column, and the pull-out force that the boss column can withstand is an important indicator to ensure product quality. , and then another worker uses the hook on the tension meter to reach the boss column of the column product, and then pulls it up until the boss 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

[0003] Moreover, the position of the tension gauge of the existing pull-out force testing device is fixed, and it is very inflexible to operate

[0004] At the same time, the existing pull-out force testing device usually presses the plastic product manually to prevent the plastic product from being pulled up together during the pull-out process, which will affect the test results. This method consumes more manpower, is not automatic enough, and affects Test efficiency
