Embodiment Construction

[0020] A material pulling step conversion mechanism, including an eccentric device 1, a single-double step conversion part 2 and a material pulling shaft part 3, wherein the eccentric device includes a connecting rod, the upper end of the connecting rod is connected to the eccentric part through a bearing, and the lower end of the connecting rod is connected to the eccentric part. Single and double-step conversion parts are connected. The connecting rod is divided into upper and lower sections 4 and 5 that are connected to each other, and is sealed with a sealing ring 6. The nut 7 plays a pressing role, and the shaft 8 is matched with the bearing 9, and then connected with the eccentric part. The nut 11 plays the role of fastening; the spring washer 12 plays the role of anti-loosening;

[0021] Said single and double-step conversion components include first and second cylinders 15 and 16, the upper ends of the first and second cylinders are connected with the connecting rod 5 o...

Abstract

The invention discloses a step pitch changing mechanism which comprises an eccentric device, a single-step and double-step changing component and a drawing shaft component, wherein the eccentric device comprises a connecting rod, the upper end of the connecting rod is connected with the eccentric component through a bearing, the lower end of the connecting rod is connected with the single-step and double-step changing component, the single-step and double-step changing component comprises a first cylinder and a second cylinder, the upper end of the first cylinder and the upper end of the second cylinder are connected with the connecting rod of the eccentric device through connecting pieces, the lower end of the first cylinder and the lower end of the second cylinder are connected with a rocking rod, the drawing shaft component comprises a rotary shaft connected with the rocking rod of the single-step and double-step changing component, a machine frame playing a role in fixing is installed on the rotary shaft, the rotary shaft is connected with a link gear converting the rotation of the rotary shaft into rectilinear motion, and the connecting rod is divided into an upper section and a lower section which are connected with each other. The step pitch changing mechanism is reasonable in structure and capable of greatly improving accuracy of step pitch changing, consecutiveness of step pitch changing, and production efficiency.

Description

[0001] This application is a divisional application with application number: 201110412999.7, application date: 2011.12.13, and name: "Material Pulling Step Changing Mechanism". technical field [0002] The invention relates to mechanical processing technology, in particular to adjust the step distance in real time through a step distance changing mechanism, so as to change the number of feeding steps on the production line. Background technique [0003] The distance changing mechanism is a common technology in the field of mechanical processing. It is mainly used for the pulling function on the production line, and the corresponding step distance can be changed according to actual needs. [0004] After the emergence of automated production lines, it is often necessary to change the step distance in real time in some pulling processes. This process usually requires manual operation, and there are a series of problems such as high labor intensity, low production efficiency, and...
