Description

Technical Field

[0001] The utility model belongs to the technical field of limit rod production, in particular to a limit rod length detection device. Background Art

[0002] A limit rod is a device used in mechanical equipment to limit the range of motion of mechanical parts. Its main function is to ensure that the mechanical equipment operates within a safe working range to prevent equipment damage or personal injury due to exceeding the design range. The limit rod usually consists of a fixed frame and a movable rod. When the mechanical part moves to the set position, the limit rod prevents it from moving further. This set position usually corresponds to the safety boundary or working limit of the mechanical equipment. In some cases, the limit rod can also be used in conjunction with other safety devices (such as limit switches) to achieve a higher level of safety protection.

[0003] In the prior art, when limit rods are produced, some defective limit rods will appear, such as those that are too long or too short. Therefore, it is necessary to limit the length of the limit rod to an acceptable range, and it is necessary to detect the length of the limit rod. After long-term use and observation, it is found that during the current production of limit rods, most of the limit rods are measured using a ruler. This measurement method can only measure the length of a single limit rod at the same time, which increases the labor intensity of the staff and affects the efficiency of measuring the length of the limit rod.

[0004] To this end, the utility model provides a limit rod length detection device. Utility Model Content

At this time, the spacing between the limit plug plate 17 and the bottom of the first sliding groove 14 is the longest qualified length of the limit rod. The limit rod longer than the spacing between the limit plug plate 17 and the bottom of the first sliding groove 14 will be first stuck by the limit plug plate 17, and then pushed by the push plate 13 to tilt. The qualified limit rod will pass through the top of the workbench 11 parallel to the first sliding groove 14.

[0032] Working principle: The staff places the limit rod to be measured in the middle of the workbench 11, and then pulls the sliding plate 15 according to the required length. The distance between the bottom of the sliding plate 15 and the bottom of the first sliding groove 14 is the shortest qualified length of the limit rod. The limit rod shorter than the distance between the bottom of the first sliding groove 14 and the bottom of the sliding plate 15 will fall out of the surface of the workbench 11 from the first sliding groove 14. Then, the limit plug 17 is inserted into the corresponding fixing hole 16 according to the needs. At this time, the distance between the limit plug 17 and the bottom of the first sliding groove 14 is the limit rod. The longest qualified length, the limit rod that is longer than the distance between the limit plate 17 and the bottom of the first sliding groove 14 will be first stuck by the limit plate 17, and then pushed by the push plate 13 to tilt. The qualified limit rod will pass through the top of the workbench 11 parallel to the first sliding groove 14. When the unqualified limit rod falls into the collection box 3, the limit rod will hit the guide plate 5, and then the guide plate 5 will press the second spring 61. At this time, the second spring 61 will push the guide plate 5, and then the guide plate 5 will shake up and down along the second support shaft 6.
