As in chinese patent [ application number: 201620004272.3 discloses a novel wood engraver, including the operation organism, be provided with the longmen on the operation organism, the carving head is installed on the longmen, the carving head includes milling cutter and rotatory saw bit, and the top left end of operation organism still is provided with the rotatory fixture device of wood, and the rotatory fixture device of wood includes the base, be provided with stiff end device on the base, stiff end device is connected with drive mechanism, has seted up the guide rail on the base, the top right side of operation organism still is provided with the controller.

At present, the structure of the engravers on the market is similar to that disclosed in the above patent documents. As is well known, in the process of machining of the existing engraving machine, a large amount of cutting chips and dust are often generated, however, in the field, the structure of the existing engraving machine is analyzed, as can be known from the engraving machine disclosed in the patent literature, the existing engraving machine generally cannot specially design dust-proof structures such as dust covers to perform dust-proof treatment, the reason for this is that the dust covers can increase the occupied space of the machine body on one hand, on the other hand, if the dust covers are additionally arranged, the workpiece can be very inconvenient to take and place, especially when the large-sized engraved workpiece is subjected to clamping and placing, the clamping and placing itself occupy more time, and then the workpiece taking and placing time is greatly prolonged due to the interference of the dust covers. Therefore, the technicians in the field can not design the engraving machine with a dustproof cover, the most conventional common dustproof treatment is to take away part of dust by using air extraction equipment or cutting fluid, but the dustproof effect of the dustproof measures is poor, and the dustproof problem cannot be well solved. That is, in the prior art, the improvement of the machining efficiency is often replaced by the protection of sacrificing the working environment, and the improvement of the dustproof effect and the machining efficiency cannot be both achieved.

Disclosure of Invention

The utility model aims at having the above-mentioned problem to current technique, provided a dustproof engraver, the utility model provides a dustproof effect and the machining efficiency of current engraver can't compromise the technical problem who improves.

The purpose of the utility model can be realized by the following technical proposal: the utility model provides a dustproof engraver, includes frame, toolframe and the workstation that is used for the clamping work piece, a serial communication port, dustproof engraver is still including the dust cover that has the work piece and imports and exports, frame, toolframe and workstation all are located the dust cover, the guide rail has been linked firmly in the frame, the guide rail imports and exports from the dust cover via the work piece outside extending to the dust cover, workstation sliding connection just can pass through on the guide rail the work piece is imported and exported whole or partial slip to the dust cover outside.

Different from the conventional design means of replacing the protection of the sacrifice working environment for the improvement of the processing efficiency in the prior art, the carving machine has the advantages of improving the dustproof effect and the processing efficiency. Particularly, in order to improve the dustproof effect, the dustproof cover is arranged on the rack, and the rack, the tool rest for processing the workpiece and the workbench are positioned in the dustproof cover, namely the dustproof cover is covered outside the processing area, so that the processing area is blocked from the outside, cuttings and dust are not easy to escape, and the dustproof effect is greatly improved; meanwhile, the utility model discloses a work piece exit that is used for the work piece business turn over is designed on the dust cover, then through designing the guide rail in the frame, make the workstation sliding connection that is used for the clamping work piece on the guide rail, because the guide rail stretches out outside the dust cover from the dust cover in via the work piece exit, make the workstation can be along the guide rail through the work piece exit from the dust cover in whole or part removal stretch out the dust cover, thereby make the work piece can get and put the clamping outside the dust cover, make the getting and putting clamping of work piece not receive the interference influence of dust cover, and above-mentioned workstation roll-off design also makes the interference of cutter frame and peripheral frame when large-scale work piece clamping, and then improved the convenience of getting and putting of work piece, guaranteed the improvement of machining efficiency; that is to say, through the sliding design of above guide rail and workstation, it brings the work piece to get to put inconveniently to have overcome above-mentioned dustproof design ingeniously, influences the problem that machining efficiency improves, consequently, through the cooperation design of above dust cover, guide rail and workstation for this engraver can compromise improvement machining efficiency again when improving dustproof effect, has improved the application prospect of engraver greatly. In addition, the above-mentioned two cases of the rack being located in the dust cover are included, and it means that a part of the rack is located in the dust cover or the whole rack is located in the dust cover.
