Safety shoe compression-resistant and piercing-resistant performance inspection device

Abstract

The invention discloses a safety shoe compression-resistant and piercing-resistant performance inspection device. A main oil cylinder is installed on a machine base through a two-dimensional motion platform, a main piston is installed in the main oil cylinder, a lower module is installed on a workbench, and an upper module is installed on the lower module. The bottom of a left guide column and the bottom of a right guide column are both installed on the machine base, a left guide sleeve is installed in an installing hole in the upper left side of a pressure head, a left locknut is installed at the top end of the left guide column, a right guide sleeve is installed in an installing hole in the upper right side of the pressure head, and the upper end of the right guide column is installed in an installing hole in the right side of a cross beam. A right locknut is installed at the top end of the right guide column, a lifting oil cylinder is installed on the bottom face of the cross beam, a lifting piston is installed in the lifting oil cylinder, and a lifting oil cylinder cover is installed on the bottom face of the lifting oil cylinder. The pressure head is installed on the bottom face of the lifting piston through a screw, a barbed nail is installed in the installing hole in the bottom of the pressure head. The structure is simple, detection of compression-resistant and piercing-resistant performance of safety shoes is achieved through hydraulic drive, lifting drive is stable, and automatic control work is easily achieved.

Description

technical field [0001] The invention belongs to the technical field of footwear detection, and in particular relates to a safety shoe compression-resistant and puncture-resistant performance inspection device. Background technique [0002] Safety shoes are a general term for safety shoes and protective shoes, and generally refer to footwear worn in different workplaces to protect feet and legs from foreseeable injuries. Safety protective shoes are high-tech and high-value-added footwear products. The production process of safety protective shoes has high requirements for raw materials, auxiliary materials, chemicals, mechanical equipment, etc. At present, many shoe-making companies with a certain scale and grade in China Enterprises have set their sights on safety and protective shoes, a market area previously occupied by developed countries. [0003] The pressure testing machine used in the existing safety shoe compression resistance and puncture resistance performance ins...

Problems solved by technology

When this product is manufactured, the trapezoidal thread of the screw sleeve and the screw rod requires high precision, otherwise it will easily cause displacement during the test process, which will increase the error of the test force, and even after a certain pressure, the screw sleeve and the screw rod will not rotate smoothly. Flexible or even stuck, making testing impossible

If the worm gear is used to drive the rotation of the screw sleeve to make the screw move up and down, the worm gear also has relatively high requirements for machining accuracy, and is often affected by a certain pressure during the test process, so that the worm gear cannot be used due to clearance fit. movement, thereby interrupting the test
