Description

Technical Field

[0001] The utility model relates to the technical field of machining centers, in particular to a crane-type five-axis gantry machining center. Background Art

[0002] The machining center is developed from the CNC milling machine. The biggest difference between the machining center and the CNC milling machine is that the machining center has the ability to automatically exchange machining tools. By installing tools of different purposes on the tool magazine, the machining tools on the spindle can be changed through the automatic tool changer in one clamping to achieve multiple machining functions.

[0003] The five-axis linkage machining center, also known as the five-axis machining center, is a high-tech, high-precision machining center specifically used for machining complex surfaces. This machining center system has a significant influence on a country's aviation, aerospace, military, scientific research, precision machinery, high-precision medical equipment and other industries.

[0004] When the machining center is processing parts, a large amount of debris will be generated. Usually, an air pump is set to absorb and concentrate the debris to facilitate subsequent cleaning. However, the position of the suction pipe is not easy to adjust, which limits the cleaning angle of the debris and creates dead angles for absorption, which makes it easy to miss parts. Therefore, it is necessary to propose a crane-type five-axis gantry machining center. Utility Model Content

A toothed disc 12 is fixedly connected with the output end of the driving motor 5, and the toothed disc 12 is meshed and connected with the bottom end of the driving sleeve 19 on the inner side;

[0030] The quick loading and unloading mechanism 10 includes a fixed cylinder 14 located between the air inlet end 6 and the air inlet pipe 8, a filter screen 15 is fixedly connected to the middle of the fixed cylinder 14, and extension sleeves 16 are provided at both ends of the fixed cylinder 14, and a clamping sleeve 17 is fixedly connected to the outer end of the extension sleeve 16.

[0033] Example 2

[0034] Reference Figure 2 and Figure 4 , which is the second embodiment of the utility model, and this embodiment is based on the previous embodiment.

[0035] The rotating mechanism 13 includes a movable ring 18 movably connected to the side of the support plate 3, a driving sleeve 19 is fixedly connected to the outer side of the movable ring 18, an air guide ring 20 is fixedly connected to the outer side of the driving sleeve 19, a group of straws 21 are fixedly connected to the bottom surface of the air guide ring 20, and a plurality of balls 22 are arranged on both sides of the movable ring 18.

[0036] Specifically, the ball 22 is movably connected to the movable ring 18, and one side of the ball 22 contacts the inner surface of the support plate 3. The straw 21 is arranged in a bent shape, and a plurality of straws 21 are arranged in a circular array with the center of the movable ring 18 as the center of the circle.

[0037] Furthermore, the debris is absorbed and blown through the intake pipe 8 in cooperation with the exhaust pipe 9, and the toothed disc 12 drives the drive sleeve 19 to rotate.

After completing the processing work, turn off the air pump 4 and the drive motor 5, rotate the extension sleeves 16 at both ends of the fixed cylinder 14, so that the two inner clamping sleeves 17 are separated from the intake end 6 and the exhaust end 7 respectively, and the two outer clamping sleeves 17 are separated from the intake pipe 8 and the exhaust pipe 9 respectively, completing the removal of the fixed cylinder 14, cleaning the debris inside the fixed cylinder 14, and then installing the fixed cylinder 14 so that the two fixed cylinders 14 are respectively fixed between the intake end 6 and the intake pipe 8 and between the exhaust end 7 and the exhaust pipe 9, which is convenient for subsequent use.
