The invention discloses a pressure testing machine driving device, and relates to the mechanical field. The pressure testing machine driving device comprises a driving rack, a driving gear, a motor transmission structure and a servo motor. One end of the driving rack is connected with a main pressure head of the pressure testing machine. The driving rack is meshed with the driving gear, and the driving gear is connected to the servo motor through the motor transmission structure. The motor transmission structure at least includes a driving wheel, and the driving wheel is in driving connectionwith the driving gear and rotates synchronously with the driving gear. The diameter of the driving wheel is larger than that of the driving gear. Compared with the screw driving mode, the device can further enlarge the force value output by the servo motor by several times, and adopt the rack and gear structure instead of the screw as the maximum force bearing part, thereby reducing the load of the screw. The aim of driving a large-ton pressure testing machine with the low-power servo motor and small-load motor driving structure can be achieved, and the cost advantage and the manufacture accuracy requirement advantage are obvious.
Description
technical field [0001] The invention relates to the mechanical field, in particular to a driving device for a pressure testing machine. Background technique [0002] The pressure testing machine is mainly suitable for testing various physical and mechanical properties of materials such as rubber, plastic sheets, pipes, profiles, plastic films, wires and cables, waterproof coils, metal wires, cartons, etc. The compressive strength of materials in different industries is different, so The range of the pressure testing machine is also different, and the large tonnage pressure testing machine usually refers to the pressure testing machine with a range of more than 300KN. [0003] Large-tonnage pressure testing machines mainly use two driving methods: hydraulic cylinder and servo motor-driven screw. Compared with hydraulic cylinder, servo motor-driven screw has the advantages of high precision and low energy consumption, and is generally used in high-end pressure testing machines...
