Description

Technical Field

[0001] The utility model belongs to the field of optical fiber laser marking machines, and particularly relates to a multifunctional clamp for optical fiber laser marking machines. Background Art

[0002] Laser marking machines can mark the parts to be marked. The parts to be marked usually include plane parts and shaft parts. The above two parts belong to different types of parts. When it is necessary to mark shaft parts, the corresponding marking fixture needs to be replaced to perform the marking operation. In small batch production, it is impossible to quickly switch between the clamping of shaft parts and plane parts, which will affect production efficiency. Therefore, a fixture suitable for marking plane parts and shaft parts is needed to improve production efficiency.

[0003] For example, the patent document with patent application number 202320412336.3 discloses a fixing fixture for a fiber laser marking machine.

The combination of the turning handle and the positive and negative threaded rod is used, and the two clamps can move relative to each other. The fixture can clamp flat parts. It is not only simple in structure but also easy to use. However, the fixture cannot rotate and mark shaft parts and is only suitable for marking flat parts. When it is necessary to mark shaft parts, the above-mentioned fixture needs to be replaced with a fixture suitable for marking shaft parts, which reduces production efficiency. Utility Model Content

The axial part clamping device includes a first roller 7, a second roller 8, a first slide 12, a second slide 13, a guide rail 2 and a driving member 23. There are two support plates 1. One end of the two support plates 1 is respectively fixed to the two ends of the base 9, and the other end of the support plate 1 extends above the base 9. The two ends of the guide rail 2 are respectively fixed to the other ends of the two support plates 1.

The third guide groove 20 is arranged in a manner, the second screw rod 22 is installed in the second guide groove 19 and the third guide groove 20, the threads at both ends of the second screw rod 22 are rotated in opposite directions, the third slider 14 and the fourth slider 15 are respectively threadedly connected to the two ends of the second screw rod 22, one end of the second screw rod 22 extends out of the base 9 and is installed with a third handle 11, holding the third handle 11 and rotating the second screw rod 22 can drive the third slider 14 and the fourth slider 15 to move closer to or away from each other, so that the first slider 16, the second slider 17, the third slider 14 and the fourth slider 15 form a limiting area, and the first slider 16, the second slider 17, the third slider 14 and the fourth slider 15 are driven by rotating the second screw 22 and the third screw to cooperate with each other to clamp planar parts of different sizes.
