Problems solved by technology

[0004] Compared with the above-mentioned three-dimensional engraving machine models, only the clamping method in the horizontal direction can be used for clamping. It is difficult to engrave the concave grooves on the inclined groove wall with the vertical clamping on the multi-head tool holder for thick and long workpieces. groove, and also difficult to clamp because of the high height
Although it is more convenient to use horizontal clamping, the height of the clamping mechanism of this type of engraving machine has been fixed, resulting in a limited height between the tool and the clamping mechanism.
Therefore, it becomes very difficult for the engraving machine of this type to process short and small workpieces, and it is difficult to engrave the inclined and concave groove surface due to insufficient length and angle.
Therefore, this type of engraving machine is generally only suitable for processing thick and long workpieces, and it is more difficult to process short and small parts.

Embodiment 1

[0043] Such as figure 1 and combine Figure 2-5 As shown, the three-dimensional engraving machine is a multi-knife six-axis three-dimensional engraving machine, including a base 1 and a gantry beam 11. The support frames 1a on both sides of the base 1 are higher than the middle part, and each support frame 1a is fixed with a horizontal longitudinal guide rail. 6a, on the horizontal longitudinal guide rail 6a, there is a longitudinal drag frame 7 slidingly connected, the gantry beam 11 is a straight strip shape, and its two ends are fixed on the longitudinal drag frame 7 so that the gantry beam 11 can move horizontally and longitudinally, and the base under the gantry beam 11 1 is connected with a support platform 2, and on the gantry beam 11 is provided with a long strip-shaped tool holder 3 with several cutter heads 3a, the tool holder 3 can form a three-dimensional translation relative to the support platform 2, and the tool holder 3 can be The strip direction of the tool r...

Embodiment 2

[0051] Embodiment two is basically the same as embodiment one, the difference is: as Image 6 As shown, the middle part of the gantry beam 11 is fixedly connected with the vertical guide rail 6c through the mounting plate, and the vertical drag frame 8 is slidably connected to the vertical guide rail 6c. Connected to the vertical frame 8; the support platform 2 is connected to the base 1a through the horizontal guide rail 6b so that the support platform 2 can move horizontally and laterally.

Embodiment 3

[0053] The third embodiment is basically the same as the first embodiment, the difference is: as Figure 7 As shown, the gantry 12 arranged on the base 1 includes two uprights 12a slidingly connected with the base 1, and the two uprights 12a are connected and fixed by a connecting beam 12b to form a U-shaped gantry 12. Two upright columns 12a are fixedly connected on the longitudinal drag frame 7 so that the gantry 12 can move horizontally and vertically. Vertical guide rails 6c are respectively fixedly connected on the two upright columns 12a, and a vertical drag frame 8 is slidably connected on each group of vertical guide rails 6c to make the gantry 12 move vertically and horizontally. The vertical carriage 8 can move vertically up and down, and the vertical carriage 8 is provided with a mounting seat 8a, and the two ends of the tool holder 3 are rotatably connected to the mounting seat 8a. The support platform 2 is connected on the base 1a through the horizontal horizontal...

Abstract

The invention provides a three-dimensional engraving machine and belongs to the technical field of machines. The three-dimensional engraving machine solves the problem of how to improve the applicability of an existing three-dimensional engraving machine. The three-dimensional engraving machine comprises a base and a gantry cross beam capable of moving horizontally and longitudinally. A support table is arranged below the gantry cross beam. A cutter frame in a strip shape and with a plurality of cutter heads is connected to the gantry cross beam through a translation structure. The cutter frame forms three-dimensional translation relative to the support table. A workbench in a strip shape is arranged on the support table. A plurality of groups of positioning components for positioning workpieces are arranged on the workbench. The workbench and the cutter frame are arranged in parallel. The support table is provided with clamping pieces which can be in the same number as the positioningcomponents and opposite to the positioning components in position, the workbench can be changed between a first position and a second position, and when the workbench is in the second position, the positioning components are matched with the clamping pieces to clamp the workpieces. By the adoption of the three-dimensional engraving machine, the application range of processing is widened under thecondition of ensuring the efficiency.

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to a three-dimensional engraving machine with multiple cutter heads for simultaneous processing, in particular to a multi-cutter six-axis three-dimensional engraving machine. Background technique [0002] There are many models of three-dimensional engraving machines, which can be applied to processing and engraving of wood, stone, metal, plastic, etc. also appeared one after another. In order to improve processing efficiency, it is the best way to improve efficiency in the field of three-dimensional engraving machines when multiple cutter heads are processed at the same time. Therefore, multiple cutter heads are set on the tool holder for synchronous movement and simultaneous processing. [0003] Such as Chinese patent application number is CN201520018008.0 patent discloses a kind of three-dimensional engraving machine, comprises frame and engraving platform; The four-jaw self-cen...
