Description

Technical Field

[0002] With the rapid development of the panel furniture industry, drilling production lines are gaining more and more favor in the market. The traditional two-machine connection is to connect the CNC drilling center through a conveyor, which leads to a large footprint and high equipment investment, which invisibly increases the cost of the enterprise. Therefore, CNC drilling centers with a double-station layout have appeared on the market, which reduce the floor space and equipment costs through a compact double-station layout.

[0003] As the market's requirements for furniture appearance continue to increase, various invisible connectors are becoming more and more popular, and the tools used to process the grooves of various invisible connectors are often not the same. Each station of the traditional double-station CNC drilling center often has only two upper and lower spindles, and the number of tools that can be installed can no longer fully meet the market's demand. The more common practice is to constantly change the tools or transfer them to another machine for separate processing, which will undoubtedly reduce the company's production efficiency.

[0004] Therefore, there is an urgent need in the art to provide a dual-station CNC drilling center with multi-spindle collaboration to address the deficiencies in the above-mentioned prior art. Utility Model Content

DETAILED DESCRIPTION

[0038] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0039] refer to Figure 1-Figure 7The embodiment of the utility model provides a dual-station CNC drilling center with multi-spindle cooperation. The dual-station CNC drilling center specifically includes a left station A and a right station B, and both the left station A and the right station B are provided with a clamp beam 1, a feed conveyor 2, a work table 3, a discharge conveyor 4, a left head component 5, a right head component 6 and a lower head component 7. Among them, a clamp transverse guide rail 1-1 and a clamp mechanism 8 installed on the clamp transverse guide rail 1-1 are provided on the clamp beam 1, the feed conveyor 2, the work table 3, and the discharge conveyor 4 are arranged in sequence along the direction of the clamp transverse guide rail 1-1, an upper head beam 9 is provided above the work table 3, and the upper head beam 9 is provided with an upper head transverse guide rail 9-1, the left head component 5 and the right head component 6 are both installed on the upper head transverse guide rail 9-1, a lower head beam 10 is provided below the work table 3, and the lower head beam 10 is provided with a lower head transverse guide rail 10-1, the lower head component 7 is installed on the lower head transverse guide rail 10-1, and the upper head transverse guide rail 9-1 and the lower head transverse guide rail 10-1 are both perpendicular to the clamp transverse guide rail 1-1. The worktable 3 is densely covered with air holes, and the friction between it and the workpiece can be reduced by connecting to an external air source, thereby protecting the outer surface of the workpiece. At least two clamping mechanisms 8 are installed on the clamping beam 1 of each station. The left head component 5 and the right head component 6 are used to process the upper surface and side surface of the workpiece (holes, grooves), and the lower head component 7 is used to process the lower surface of the workpiece (holes, grooves).

[0040] In the double-station CNC drilling center of the embodiment of the utility model, the left station A and the right station B are not electrically connected, and are controlled on different sides, so they do not interfere with each other during operation. This reduces the floor space while greatly reducing the difficulty of operation. On the other hand, even if one station fails, it will not affect the operation of the other station, thereby virtually improving the efficiency of machine use.

[0041] The working process of the duplex CNC drilling center of the embodiment of the utility model is roughly as follows: after the machine starts to operate, the feed conveyor 2 feeds the workpiece from the front end. After the positioning operation, the clamping mechanism 8 clamps the workpiece to a specific position on the work surface 3 according to the program. At this time, each head component performs drilling or milling processing according to the program. After the processing is completed, the clamping mechanism 8 clamps the workpiece to the discharge conveyor 4, returns to the feed area and starts the next cycle, and the processed workpiece continues to be transported and discharged by the discharge conveyor 4.

Both ends of the middle section of the clamp beam 1 are provided with guide rail connection grooves 1-3, and the position of the guide rail connection grooves 1-3 corresponds to the position of the clamp transverse shift guide rail 1-1. This detachable three-section design can remove only the front section and the rear section of the clamp beam 1 during packaging, and package the front and rear sections of the clamp beam 1 separately, leaving the middle section of the clamp beam 1 for the clamp mechanism 8 to be placed. At this time, there is no need to disconnect the electrical connection between the clamp mechanism 8 and the host, which can greatly reduce the difficulty of packaging. In addition, when the front, middle and rear sections of the clamp beam 1 need to be spliced ​​together, the guide rail connecting grooves 1-3 can ensure the accuracy of the splicing and prevent the guide rail or rack from being offset.
