Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of helmet fixtures, in particular to a helmet laser trimming fixture. Background Art
[0002] Bulletproof helmets are generally molded with aramid cloth or other fiber cloth impregnated with resin. First, the aramid cloth impregnated with resin is laid layer by layer into the mold, and then it is made by molding. The helmet body made by molding has a fiber cloth edge around it, which needs to be cut off by a laser cutting machine. The existing helmet laser trimming machine includes a laser cutting head, a positioning sensor on a positioning rod and a helmet tray. A "U"-shaped limit frame is arranged on the helmet tray, and the two sides of the helmet are stuck on the outside of the limit frame. Because the placement position of the helmet is not very accurate, before trimming, it is necessary to adjust the positioning sensor on the positioning rod to determine the base point position of the laser cutting head. The above method has the following technical defects: First, after each helmet is placed on the limit frame, the positioning sensor on the positioning rod needs to be adjusted, which has low work efficiency; second, the operator completes the moving position of the positioning sensor based on visual inspection, which has large errors and poor product quality. Utility Model Content
[0003] The technical problem to be solved by the utility model is to provide a laser trimming fixture for helmets which has high working efficiency, good product quality and is easy to use.
[0004] In order to solve the above problems, the technical solution adopted by the utility model of the helmet laser trimming fixture is: it includes a fixed base, a head mold is fixed on the fixed base, at least four cylinder positioning holes are arranged at equal circumferential angles near the upper part of the head mold, a cylinder with a push rod facing radially outward is arranged in each of the cylinder positioning holes, a cylinder fixing frame is arranged inside the head mold, each of the cylinders is fixed on the cylinder fixing frame, a gas conduit connected to each of the cylinders is arranged on the cylinder fixing frame, and the gas conduit is connected to the air pump through a foot switch; a base point marking line is arranged near the front of the head mold.
[0005] Its additional technical features are:
[0006] An elastic top sheet fixed to the top rod is arranged on the outside of the top rod;
[0007] The number of the cylinder locating holes and the number of the cylinders is four, six or eight.
[0008] Compared with the prior art, the helmet laser trimming fixture provided by the utility model has the following advantages: first, since it includes a fixed base, a head mold is fixed above the fixed base, at least four cylinder positioning holes are arranged at equal circumferential angles near the upper part of the head mold, a cylinder with a push rod facing radially outward is arranged in each of the cylinder positioning holes, a cylinder fixing frame is arranged inside the head mold, each of the cylinders is fixed on the cylinder fixing frame, a gas conduit connected to each of the cylinders is arranged on the cylinder fixing frame, the gas conduit is connected to the air pump through a foot switch, a base point marking line is arranged near the front of the head mold, the fixed base is fixed to the tray on the laser cutting machine, and the head to be trimmed is placed on the fixed base. The helmet is put on the head mold, and the center position of the front of the helmet roughly coincides with the base point marking line. By stepping on the foot switch to supply air to the cylinder, the push rod on the cylinder extends from the cylinder positioning hole. When each cylinder push rod is extended, the helmet is exactly in the set position. At this time, it can be directly cut with a laser cutting head without adjusting the positioning sensor on the positioning rod. The cutting is more accurate, the product quality is high, and the production efficiency is improved; secondly, since an elastic top plate fixed to the push rod is provided on the outside of the push rod, after the position of the helmet is offset, the cylinder push rod will not cause damage to the helmet, and the positioning is more accurate; thirdly, since there are four, six or eight cylinder positioning holes and cylinders, the positioning accuracy is greater and the quality of the produced helmets is higher.

[0013] The structure and use principle of the laser trimming fixture for helmets of the utility model are further described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0014] like Figure 1 and Figure 2As shown, a schematic diagram of the structure of a laser trimming fixture for helmets of the utility model is shown, which comprises a fixed base 1, a head mold 2 is fixed above the fixed base 1, at least four cylinder positioning holes 3 are arranged at equal circumferential angles near the upper part of the head mold 2, a cylinder 5 with a push rod 4 radially outward is arranged in each cylinder positioning hole 3, a cylinder fixing frame 6 is arranged inside the head mold 2, each cylinder 5 is fixed on the cylinder fixing frame 6, a gas conduit 7 connected to each cylinder 5 is arranged on the cylinder fixing frame 6, the gas conduit 7 is connected to the air pump 9 through a foot switch 8, and a base point marking line 10 is arranged near the front of the head mold 2.
[0015] Fix the fixed base 1 to the tray on the laser cutting machine, put the helmet to be trimmed on the head mold 2, the front center position of the helmet roughly coincides with the base point marking line 10, and supply air to the cylinder 5 by stepping on the foot switch 8. The push rod 4 on the cylinder 5 extends from the cylinder positioning hole 3. When the push rod 4 of each cylinder is extended, the helmet is exactly in the set position. At this time, it can be cut directly with the laser cutting head without adjusting the positioning sensor on the positioning rod. The cutting is more accurate, the product quality is high, and the production efficiency is improved.
[0016] An elastic top sheet 11 fixed to the push rod is arranged outside the push rod 4. After the position of the helmet is offset, the cylinder push rod will not cause damage to the helmet, and the positioning is more accurate.
[0017] like Figure 2 As shown, there are four cylinder locating holes 3 and four cylinders 5. Of course, Figure 3 As shown, there are six cylinder positioning holes 3 and six cylinders 5; or Figure 4 There are eight cylinder positioning holes 3 and eight cylinders 5, so the positioning accuracy is greater and the quality of the produced helmet is higher.
[0018] The protection scope of the present invention is not limited to the above-mentioned embodiments. As long as the structure is the same or similar to the structure of the helmet laser trimming fixture of the present invention, it falls within the protection scope of the present invention.
