Description

Technical Field

[0001] The utility model relates to the technical field of mechanical equipment, in particular to a small-pitch continuous dot marking machine. Background Art

[0002] Before the tensile test of steel bars, steel pipes, steel sections or other non-ferrous metal materials, they must first be dotted and marked. However, the method of using a measuring ruler to mark section by section is no longer applicable due to defects such as large marking errors and low marking efficiency. Nowadays, continuous marking machines are mostly used to achieve dot marking of steel bars, steel pipes, steel sections or other non-ferrous metal materials. When using a continuous marking machine for dot marking, the frame with dot marking needles is hinged on the main body of the equipment. After the sample is placed in the sample slot, the frame with dot marking needles needs to be rotated so that the tip of the dot marking needle abuts against the sample. Then, one hand presses the frame and the other hand turns the handle to control the dot marking needle to rise and fall. The operation requirements of the whole process are relatively harsh, and due to the influence of human operation factors, unclear dot marking may occur. In addition, the existing continuous marking machine is difficult to accurately locate the marking materials of different diameters, and it is inconvenient to operate when marking.

[0003] In order to solve the deficiencies of the prior art, people have conducted long-term exploration and proposed various solutions. For example, the Chinese patent document discloses a continuous marking machine [CN202110277953.2], which includes a frame; a clamping device, which is slidably arranged on the frame; a first lead screw, which is rotatably connected to the lower part of the frame, and has threads with opposite rotation directions at both ends; two sliders, which are respectively threadedly connected to the first lead screw; a connecting rod, which corresponds to the slider one by one, one end of which is hinged to the slider and the other end is hinged to the clamping device; a first positioning plate, which is fixedly arranged on the frame and located above the clamping device; a second positioning plate, which is fixedly arranged on the frame, located above the first positioning plate and parallel to the first positioning plate; a marking rod, which is arranged at intervals on the first positioning plate and the second positioning plate; a top, which is arranged at the lower end of the marking rod; a limit plate, which is fixed on the marking rod and located between the first positioning plate and the second positioning plate; a spring, which is sleeved on the marking rod, one end of which is abutted against the first positioning plate and the other end is abutted against the limit plate; and a driving mechanism.

[0004] The above scheme solves the problem of unclear marking in the continuous marking machine in the prior art to a certain extent, but the scheme still has many shortcomings, such as: it is difficult to accurately locate the marking materials of different diameters, and it is inconvenient to operate when marking.
