Description

Technical Field

[0001] This utility model relates to the technical field of CNC machine tool processing equipment, specifically to an automatic head-changing auxiliary device for a fixed-beam gantry machining center. Background Technology

[0002] The fixed-beam gantry machining center is a series of boring and milling machines with a moving worktable. The automatic head change device in the head compartment of the fixed-beam gantry machining center is mainly used on large industrial machine tools such as gantry machines to process the sides of workpieces, reduce the need for secondary clamping of workpieces, improve production efficiency, and ensure workpiece machining accuracy. However, the existing automatic head change device is placed separately on the foundation and positioned independently, without a rigid connection to the industrial machine tool. Therefore, when the angle head (an accessory head used to complete side machining) on ​​the automatic head change device needs to be used, there will be a positional deviation between the angle head and the gripping mechanism on the industrial machine tool. If the deviation is large, head change failure or even machine collision may occur. This requires frequent adjustment of the position of the angle head or the gripping mechanism on the industrial machine tool to ensure alignment and docking, which is a relatively cumbersome operation. Utility Model Content

[0003] To address the aforementioned issues, this utility model provides an automatic head-changing auxiliary device for a fixed-beam gantry machining center. It is simple and convenient to operate, requires no frequent adjustments to the position and angle, and ensures the stability of the assembly and use between the angle head and the industrial machine tool.

[0004] This utility model adopts the following technical solution: an automatic head-changing auxiliary device for a fixed-beam gantry machining center, mounted on a gantry frame. The gantry frame includes a column and a crossbeam mounted on the column. The device includes a fixing plate mounted on the column.

The fixing frame and fixing seat are slidably mounted on the linear guides via sliders. Two sets of driving cylinders are mounted on the fixing plate, and the two sets of driving cylinders are respectively connected to the fixing frame and fixing seat. A positioning plate is mounted on the fixing frame, and a positioning post is provided on the positioning plate. A dust cover is placed on the positioning post. An installation opening is opened at the top of the fixing seat, and an angle head is placed inside the fixing seat through the installation opening. A gripping mechanism for gripping the angle head is mounted on the crossbeam.

[0005] Furthermore, the gripping mechanism includes a casting capable of moving in the X-axis and Y-axis directions. The bottom end of the casting is provided with a connecting plate, the center of which has a first through hole. The bottom end of the casting is equipped with a vacuum suction cup, the lower end of which passes through the first through hole.

[0006] Furthermore, the dust cover has a circular structure, and a protrusion is provided in the center of the dust cover.

[0013] Figure 2 This is a schematic diagram of the gripping mechanism in this utility model. Detailed Implementation

[0014] like Figure 1 , Figure 2 As shown, this utility model discloses an automatic head-changing auxiliary device for a fixed-beam gantry machining center. The device is mounted on a gantry frame, which includes a column 1 and a crossbeam (not shown) mounted on the column 1. The device includes a fixed plate 2 mounted on the column 1. Fixed frames 3 and fixed seats 4 are mounted on the upper and lower parts of the fixed plate 2. Two sets of linear guides 5 are arranged on the fixed plate 2. The fixed frames 3 and fixed seats 4 are slidably mounted on the linear guides 5 via sliders. Two sets of drive cylinders 6 are mounted on the fixed plate 2, and the two sets of drive cylinders 6 are respectively connected to the fixed frames 3 and fixed seats 4. A positioning plate 7 is mounted on the fixed frame 3, and a positioning post 8 is provided on the positioning plate 7. A dust cover 9 is placed on the positioning post 8. An installation port 10 is opened at the top of the fixed seat 4, through which an angle head 11 is placed inside the fixed seat 4. A gripping mechanism for gripping the angle head 11 is mounted on the crossbeam.

[0015] The gripping mechanism includes a casting 12 that can move in the X and Y axes. In fact, moving the casting 12 in the X and Y axes on the gantry is existing technology. The casting 12 can move in the corresponding X and Y axes by connecting existing X-axis drive mechanisms and Y-axis drive mechanisms. The bottom of the casting 12 is provided with a connecting plate 13, and the center of the connecting plate 13 has a first through hole 15. The bottom of the casting 12 is equipped with a vacuum suction cup 14, and the lower end of the vacuum suction cup 14 passes through the first through hole 15. When the angle head 11 does not need to be changed, the gripping mechanism picks up the dust cover 9 through the vacuum suction cup 14. The dust cover 9 has a circular structure, and the center of the dust cover 9 has a protrusion 16. The inner diameter of the protrusion 16 is larger than the inner diameter of the lower end of the vacuum suction cup 14, but not larger than the inner diameter of the first through hole 15.

[0016] The fixing frame 3 has a triangular structure. The positioning plate 7 has a second through hole 19. The positioning pins 8 are installed on the four corners of the positioning plate 7. The bottom surface of the dust cover 9 has positioning holes corresponding to the positioning pins 8 (not shown in the figure). The fixing frame 3 and the fixing seat 4 are both equipped with connecting plates 17. The two sets of driving cylinders 6 are respectively connected to the connecting plates 17. The mounting port 10 at the top of the fixing seat 4 is arc-shaped. Anti-wear pads 18 are provided at both ends of the top of the fixing seat 4 located at the mounting port 10.

[0017] This utility model features an integrated structural layout, which is compact and space-saving. A fixing plate 2, equipped with an angle head 11 and a dust cover 9, is fixed to the column 1 of the gantry frame, providing not only a strong rigid connection but also ensuring stability during angle head 11 replacement. Under normal circumstances, the angle head 11 is placed in the fixed base 4. When it is necessary to process the side of the workpiece, the driving cylinder 6 at the fixed frame 3 moves the fixed frame 3 containing the dust cover 9, causing the gripping mechanism to move accordingly in the X and Y axis directions, thus enabling the vacuum suction cup 1 to... 4. It can hold the angle head 11, thus enabling the angle head 11 to be changed. This allows for drilling operations on the side of the workpiece without frequent adjustments to the angle head 11 or the position of the gripping mechanism on the machine tool. The operation is simple and convenient. When the angle head 11 is not being changed, the gripping mechanism places the angle head 11 in the fixed seat 4. The fixed frame 3 is then moved again by the drive cylinder 6. The gripping mechanism then uses the vacuum suction cup 14 to pick up the dust cover 9. The dust cover 9 is attached to the bottom of the connecting plate 13, which can protect the connecting plate 13 from dust and extend its service life.
