Description

Technical Field

[0001] The utility model relates to the technical field of cable production, in particular to a dot-marking positioning fixture. Background Art

[0002] During the production of cables, one of the processes is to use a marker pen to mark the cables at regular intervals, commonly known as "dotting". For example, some processing requirements require that the cables be dotted every 10 cm, while some processing requirements require that the cables be dotted every 20 cm.

[0003] Due to different processing requirements, the dotting distance is different. Therefore, the workshop workers currently mainly dot by measuring with a handheld tape measure to control the dotting distance. However, with one hand holding the tape measure and the other hand holding the marker, there is no hand to fix the cable. Therefore, the dotting operation is very inconvenient and the production efficiency is low.

[0004] Therefore, it is necessary to develop a dot-marking positioning fixture to fix the cables in order to complete the dot-marking operation, thereby improving production efficiency.

[0005] The above information disclosed in this Background section is included only for enhancement of understanding of the background of the present disclosure and therefore it may contain information that does not form the prior art that is currently known to a person of ordinary skill in the art.

[0044] See also Figure 1 and Figure 2 The utility model provides a dotting positioning jig, including a straightening jig 1 and a plurality of dotting jigs 2. The straightening jig 1 includes a plurality of first rollers 1022, each of the first rollers 1022 is correspondingly provided with a second roller 1023, and the first rollers 1022 and the second rollers 1023 are used for rolling and straightening the cable 100 to be dotted. The dotting jig 2 is provided with a wire groove 201 for accommodating the cable 100 to be dotted; wherein, two adjacent dotting jigs 2 are detachably connected, and the dotting jig 2 closest to the straightening jig 1 is detachably connected to the straightening jig 1.

[0045] Specifically, the circumferential surface of the first roller 1022 is provided with a first arc groove 1022a for pressing one side of the cable 100 to be marked, and the circumferential surface of the second roller 1023 is provided with a second arc groove 1023a for pressing the other side of the cable 100 to be marked.

[0046] The dotting positioning jig provided in this embodiment needs to prepare dotting jigs 2 of various specifications before performing dotting operations. Dotting jigs 2 of different specifications have different lengths. For example, the length of specification A is 10 cm, the length of specification B is 20 cm, etc. According to the dotting distance, a dotting jig 2 of the corresponding specification is selected. For example, if the required dotting distance is 10 cm, multiple dotting jigs 2 of specification A are selected in advance; if the required dotting distance is 20 cm, multiple dotting jigs 2 of specification B are selected in advance.

[0047] Then, according to the length of the cable 100 to be marked, select a suitable number of dotting jigs 2, and connect each dotting jig 2 to the rear of the straightening jig 1 in turn; then, pass one end of the cable 100 to be marked between the first roller 1022 and the second roller 1023, and then insert it into the wire groove 201 of each dotting jig 2 in turn; finally, use a marking pen to mark the junction of the cable 100 to be marked corresponding to two adjacent dotting jigs 2.

[0048] The marking positioning fixture provided in this embodiment can, on the one hand, straighten and fix the cable 100 to be marked, so as to free up both hands for marking operations; on the other hand, there is no need to use a tape measure for measurement operations; therefore, the convenience of marking is greatly improved, thereby effectively improving production efficiency.
