Description

Technical Field

[0001] The utility model belongs to the technical field of sample line manufacturing tools, and in particular relates to a simple cutting table used for sample line shearing. Background Art

[0002] With the continuous growth of domestic automobile production and the continuous development and progress of new energy vehicles, automobiles are updated very quickly, and the demand and types of automobile wiring harnesses are increasing. In order to adapt to the increasingly rapid development of different types of automobiles, the automotive wiring harness industry needs to provide qualified sample line products for automobile manufacturing. In the process of sample line making, cutting out wire harnesses of suitable length is not suitable for separate programming and making on automated offline machines, which is time-consuming, labor-intensive and costly. However, if workers are asked to manually measure and then cut, not only the work efficiency is too low, but also it is easy to have large errors in wire harness length or cut out unqualified wire harnesses.

[0003] In the prior art, a patent document with announcement number CN110508722B discloses a fixed-length cutting device for wiring harness cables of new energy vehicles, including a base plate, a wire-releasing mechanism, a limiting mechanism, an electric slider, a shearing mechanism, a scale and a fixed-length mechanism. A slide groove is symmetrically opened front and back on the middle part of the top of the base plate, a wire-releasing mechanism is installed on the left side of the top of the base plate, the limiting mechanism is located on the right side of the wire-releasing mechanism, both ends of the limiting mechanism are installed on the top of the base plate, the electric slider is connected in the slide groove of the base plate in a sliding fit, a shearing mechanism is arranged on the right side of the limiting mechanism, both ends of the shearing mechanism are installed on the top of the electric slider, the scale is installed on the front side of the middle part of the top of the base plate, the fixed-length mechanism is located on the right side of the shearing mechanism, and the fixed-length mechanism is installed on the right side of the top of the base plate. The above technical solution can cut multiple wire harnesses in sequence, which improves the manufacturing efficiency. However, the installation requirements of the wire harness roll are too high and the operation is inconvenient. In addition, the scale set therein requires the wire harness on the fixed-length mechanism to be rotated a certain number of times and the scale value at the corresponding incision of the scale to obtain the size of the wire harness. It is more likely to have errors in the calculation process, and each calculation increases the burden on the operator. The shearing mechanism uses manual operation to cut multiple wire harnesses. Not only is it difficult to make the wire harness incision smooth, but it is also easy to make operational errors and injure the operator. Summary of the invention
