A multi-station processing fixture

Abstract

The invention discloses a multistation machining jig. The multistation machining jig comprises a working plate, a ratchet wheel, a pawl and a transmission mechanism, wherein a plurality of workpiece clamping parts are arranged on the upper surface of the working plate, the ratchet wheel is rigidly connected to the working plate and is concentric with the working plate, the pawl is leaned against a ratchet, and the other end of the pawl is articulated with the transmission mechanism. The transmission mechanism comprises a rocking bar, a crank and a connecting rod, wherein one side of the rocking bar is articulated with the pawl, the other side of the rocking bar is articulated with the connecting rod, the connecting rod is articulated with the crank, the crank can make circular motion, and the rocking bar can make angle swinging. The ratchet wheel makes intermittently cyclical movement so that the working plate fixedly connected to the ratchet wheel makes cyclical movement, the steps of charging, waiting, machining, discharging and the like are coherently carried out, and a machine does not need to be halted and started up every time, thus the workload of workers is reduced, and simultaneously the risk that fingers are possibly bruised when the workers feed materials is avoided.

Description

technical field [0001] The invention relates to a machined jig, in particular to a jig for thermal transfer printing. Background technique [0002] Thermal transfer is a printing method, which is divided into transfer film printing and transfer processing. Rich layers, bright colors, ever-changing, small chromatic aberration, good reproducibility, can meet the requirements of the designer, and is suitable for mass production; the transfer process is processed by a thermal transfer machine (heating and pressing) at one time. The exquisite pattern is transferred on the surface of the product. After molding, the ink layer is integrated with the surface of the product, which is realistic and beautiful, and greatly improves the grade of the product. [0003] Because each heat transfer is processed for a specific surface, each processing must include three steps, namely "loading-processing-unloading", these three stations are usually in one station Therefore, each processing nee...

Problems solved by technology

[0003] Because each thermal transfer is processed for a specific surface, each processing must include three steps, namely "loading - processing - unloading", these three stations are usually in one station Therefore, each processing needs to be started and stopped, which increases the workload of workers and reduces production efficiency.
