Abstract

The invention provides a mark engraving device. A movable upper cover is arranged above a character head slot at one side of a base and is connected to one side face of the base through a hinge in a hinging manner, the other side face of the base is provided with a shaft seat which is connected to a flat lower end of a movable screw through a connecting shaft, the upper end of the movable screw is matched with a nut, the side face of the nut is welded with a right-angled rotating rod, the other end, opposite to the hinge hinged end, of the movable upper cover extends out of the character head slot, the end part of the end, extending out of the character head slot, of the movable upper cover is in a forked shape, and a groove in the middle of the forked-shape part is matched with the upper end of the movable screw. According to the mark engraving device, the connection manner of the original upper cover is changed into hinge connection, in such a way, fonts can be frequently replaced, and the detaching time is largely saved. Bolt and nut connection is adopted at the right side, and through screwing up a spanner on the nut, the upper cover can be tightly pressed, so that the phenomenon of font fuzz caused by looseness of character heads during marking can be avoided. The mark engraving device belongs to a mechanism suitable for engraving permanent marks after an end part of which the material diameter is greater than 30mm is forged to be flat.

Description

technical field

[0001] The invention belongs to a marking and engraving device for mechanical products, in particular to a marking and engraving device. technical background

[0002] With the improvement of the quality of spring products in the railway market, the traceability of spring products is particularly important. In particular, in-road products need to pass the CRCC certification to engrave the serial number on the spring end ring of the passenger car so that the spring can be traced when quality problems occur. Therefore, each OEM requires the manufacturer to permanently mark the serial number of the spring. Due to the previous identification Only engraving the manufacturer and the year, month and month of production can be solved by changing the prefix once a month. However, due to the increase in the engraving of the serial number, since the serial number of each spring is not unique, workers need to manually tap the spring end ring in the hot state for engraving...

Examples

Embodiment Construction

[0012] A mark engraving device as shown in the figure is characterized in that: there is a prefix slot on one side of the rectangular base, a movable upper cover is arranged above the prefix slot, and one end of the movable upper cover is hinged by a hinge Connected to one side of the base, there is a shaft seat on the opposite side of the base, the shaft seat is connected to the flat lower end of a movable screw through the connecting shaft, the upper end of the movable screw is matched with a nut, and a right-angle rotating rod is welded on the side of the nut. The other end of the hinge end stretches out of the prefix slot, and the end of the movable loam cake that its end stretches out of the prefix slot is a fork, and the groove in the middle of the fork cooperates with the movable screw rod upper end.

[0013] The operating steps of the present invention are:

[0014] First turn the handle to try to loosen the nut, open the movable upper cover, put the corresponding seri...
