Description

Technical Field

[0001] This application relates to the field of engraving machine technology, and more specifically, to a multi-station, multi-head engraving machine based on an indexing plate. Background Technology

[0002] Engraving machines are CNC equipment widely used in advertising, woodworking, mold making, handicrafts and other industries. They are used to precisely engrave and cut non-metallic materials and some soft metal materials. Traditional single-head engraving machines can only process one workpiece at a time, resulting in low production efficiency. To improve efficiency, multi-head engraving machines have emerged.

[0003] However, existing multi-head engraving equipment still has obvious shortcomings. Most of the fixtures are fixed and inconvenient to replace and adjust, making it difficult to adapt to the production needs of multiple varieties and small batches. The positioning consistency of multiple fixtures is difficult to guarantee, which affects the processing accuracy. Furthermore, it is impossible to process simultaneously when loading and unloading materials, which affects work efficiency. Utility Model Content

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art or related technologies.

[0005] In view of this, the present invention proposes a multi-station multi-head engraving machine based on an indexing plate, comprising: a base, a crossbeam, a first connecting plate, a second connecting plate, multiple engraving heads, and an indexing plate. The crossbeam is slidably mounted on the base, the first connecting plate is slidably mounted on the crossbeam, the second connecting plate is slidably mounted on the first connecting plate, and the multiple engraving heads are slidably mounted on the second connecting plate. The indexing plate is rotatably mounted on the base, and multiple clamps are detachably mounted on the indexing plate. The multiple clamps are divided into four groups distributed on the indexing plate, and the number of clamps in each group is the same as the number of engraving heads. The upper surface of the indexing plate has multiple threaded holes, and the clamps have multiple mounting holes. The clamps include multiple mounting bolts, which are threaded through the mounting holes and threaded holes.

[0006] In this technical solution, the components include a base, a crossbeam, a first connecting plate, a second connecting plate, multiple engraving heads, and an indexing plate. The crossbeam is slidably mounted on the base, the first connecting plate is slidably mounted on the crossbeam, the second connecting plate is slidably mounted on the first connecting plate, and the multiple engraving heads are slidably mounted on the second connecting plate. Through the cooperation between the base, crossbeam, first connecting plate, second connecting plate, and multiple engraving heads, the multiple engraving heads can move synchronously to complete the engraving processing of multiple products simultaneously. The indexing plate is rotatably mounted on the base, and multiple clamps are detachably mounted on the indexing plate. The clamps are divided into four groups distributed on the indexing plate, and each group... The number of fixtures is the same as the number of engraving heads. After the workpieces on one set of fixtures have been engraved, the indexing plate rotates 90° to rotate another set of unprocessed workpieces under the engraving head, thus completing the processing of the second set of workpieces. Furthermore, while the workpieces on one set of fixtures are being processed, the operator can also disassemble and assemble the workpieces on the outermost fixture, achieving unloading and unloading without stopping the machine and improving work efficiency. The upper surface of the indexing plate has multiple threaded holes, and the fixture has multiple mounting holes. The fixture includes multiple mounting bolts, which are threaded through the mounting holes and threaded holes. The detachable design of the fixture allows the indexing plate to be adapted to more different fixtures, enabling diversified production.
