Description

Technical Field

[0001] The utility model relates to the technical field of machine tool precision detection, in particular to a detection tooling for the B-axis of a five-axis head. Background Art

[0002] At present, in the production of five-axis CNC machine tools, effective methods can be used for detecting the positioning accuracy of each linear axis of the X-axis, Y-axis, and Z-axis and the positioning accuracy of the rotary table rotating along the C-axis. However, there is still no efficient detection method for the spindle of the B five-axis head inclined at 45°. Currently, the existing method for detecting the positioning accuracy of the B-axis usually uses a standard inspection tool for detection, which can only detect the accuracy at positions such as 0°, 90°, and -90°.

[0030] For better explanation and understanding of the present utility model, the following will combine the accompanying drawings and make a detailed description of the present utility model through specific implementation modes.

[0031] As Figure 1 shown, the embodiment of the present utility model provides a detection tooling for the B-axis of a five-axis head, which is used to install a rotary shaft calibration device 3 and a laser emission assembly 4. Among them, the axis of the main shaft of the five-axis head is vertically oriented, and the five-axis head can drive the main shaft to move linearly along the X-axis, Y-axis, and Z-axis, and rotate around the C-axis and B-axis.

[0032] The detection tooling includes a first tooling unit 1 and a second tooling unit 2. Among them, the first tooling unit 1 includes a circular sleeve 11, a connecting plate 12, and a positioning plate 13. The first end face of the circular sleeve 11 is fixedly connected to the positioning plate 13 through the connecting plate 12, and the included angle between the axis of the circular sleeve 11 and the normal line of the positioning plate 13 is 45°. The second end face of the circular sleeve 11 is used for detachably connecting with the main shaft of the five-axis head, and the circular sleeve 11 is coaxially arranged with the main shaft of the five-axis head. Since the main shaft is vertically oriented, the circular sleeve 11 is vertically oriented. The positioning plate 13 is used for detachably connecting with the rotary shaft calibration device 3, and the rotary axis of the rotary shaft calibration device 3 coincides with the axis of the B-axis. The installation surface of the second tooling unit 2 forms an angle of 45° with the horizontal plane, and the installation surface is used for connecting with the laser emission assembly 4 so that the beam emitted by the laser emission assembly 4 is perpendicular to the mirror in the rotary shaft calibration device 3. It should be noted that the rotary axis of the rotary shaft calibration device 3 coincides with the axis of the B-axis in the five-axis head, which can truly reflect the rotary angle of the B-axis, and thus facilitate the detection of the position accuracy of the B-axis and improve the detection efficiency. In this embodiment, the working principles of the rotary shaft calibration device 3 and the laser emission assembly 4 are prior art and will not be described in detail here.

[0033] As Figure 1 shown, in the actual application process, the rotary shaft calibration device 3 includes a mirror and a rotary disk for installing and fixing the mirror. In this embodiment, the laser emission assembly 4 includes a laser head and an interferometer. Among them, both the laser head and the interferometer are vertically arranged with respect to the installation surface of the second tooling unit 2. The laser head emits a beam, and the interferometer is used to split the beam emitted by the laser head into two parallel beams. The mirror on the rotary shaft calibration device 3 is used to reflect the two parallel beams split by the interferometer back to the interferometer to form an interference pattern for the laser head to analyze.

[0034] Among them, the rotary shaft calibration device 3 and the laser emission assembly 4 work together through precise optical measurement principles to achieve accurate measurement and calibration of the position accuracy of the rotary shaft. The specific working principle is prior art and will not be elaborated here.

[0035] The purpose of this detection tooling is to facilitate the installation of the rotary shaft calibration device 3 and the laser emission component 4, enabling it to directly measure the positional accuracy of the B-axis in the five-axis head.

[0036] This detection tooling has a simple structure and strong practicability. It can enable the rotary shaft calibration device 3 and the laser emission component 4 to cooperate accurately and quickly to detect the positional accuracy of the B-axis at an angle of 45° in the inclined vertical direction, improving the detection efficiency.

[0037] As Figure 3 and Figure 4 shown, the connecting plate 12 is perpendicular to the positioning plate 13. The connecting plate 12 is provided with a first mounting surface 121 and a second mounting surface 122. To facilitate the positioning connection between the circular sleeve 11 and the connecting plate 12, the included angle between the first mounting surface 121 and the second mounting surface 122 is 90°. The included angle between the first mounting surface 121 and the positioning plate 13 is 45°, and the included angle between the second mounting surface 122 and the positioning plate 13 is 45°. The side wall of the circular sleeve 11 is connected to the first mounting surface 121, and the first end face of the circular sleeve 11 is connected to the second mounting surface 122. Specifically, the first mounting surface 121 is welded to the side wall of the circular sleeve 11, and the second mounting surface 122 is welded to the first end face of the circular sleeve 11.

[0038] As Figure 3 shown, a flange is formed by the first end face of the circular sleeve 11 extending radially outward. A plurality of first mounting holes 111 are provided on the flange. The circular sleeve 11 is detachably connected to the main shaft through a first screw passing through the plurality of first mounting holes 111. To avoid interference between the first screw and the side wall of the circular sleeve 11, a plurality of avoidance holes 112 are provided on the side wall of the circular sleeve 11. The plurality of avoidance holes 112 are arranged in one-to-one correspondence with the plurality of first mounting holes 111, and the avoidance holes 112 are used to avoid the first screw in the first mounting holes 111.

[0039] To facilitate the coincidence of the rotation axis of the rotary shaft calibration device 33 with the axis of the B-axis, a centering hole 131 is provided at the center of the positioning plate 13. The center of the rotary disk in the rotary shaft calibration device 3 installed on the positioning plate 13 coincides with the centering center, that is, the rotation axis of the rotary shaft calibration device 3 is coaxial with the centering hole 131. Among them, the center of the centering hole 131 coincides with the axis of the B-axis, and thus the coincidence of the rotation axis of the rotary shaft calibration device 33 with the axis of the B-axis can be achieved. Therefore, during the production process, the coincidence of the centering hole 131 on the positioning plate 13 with the axis of the B-axis can be ensured by measuring with a lever dial indicator. The specific operation and working principle of the dial indicator are all prior arts and will not be elaborated here.

[0040] As Figure 2 and Figure 3As shown in the figure, for the convenience of installing the rotary shaft calibration device 3, a plurality of second mounting holes 132 are further provided on the positioning plate 13, and the positioning plate 13 is connected to the rotary shaft calibration device 3 through the second screws passing through the second mounting holes 132.

[0041] As Figure 1 and Figure 5 shown, the second tooling unit 2 includes an adapter body 21 and a tripod 22, and the adapter body 21 is arranged on the tripod 22. The adapter body 21 is provided with a third mounting surface 211, and the third mounting surface 211 is the mounting surface of the second tooling unit 2. The included angle between the third mounting surface 211 and the horizontal plane is 45°. The third mounting surface 211 is vertically arranged and detachably connected to the laser head and the interferometer in the laser emission assembly 4, and the light beam emitted by the laser head is perpendicular to the interferometer. Through the settings of the first tooling unit 1 and the second tooling unit 2, the position requirements that the reflectors on the rotary shaft calibration device 3 and the interferometers of the laser emission assembly 4 are parallel and relatively arranged can be achieved.
