Description

Technical Field

[0001] This utility model is applied in the field of mechanical equipment, specifically relating to a milling head segmentation angle detection mechanism. Background Technology

[0002] Existing milling head segmentation angle detection structures mostly adopt a direct connection structure between the encoder and the bevel gear shaft. There is a gear backlash between the rotation angle of the milling head A-axis and the angle measured by the encoder. This gear backlash will cause errors, and the angle measured by the encoder will be inaccurate, which cannot meet the needs of production. Utility Model Content

[0003] Purpose of the utility model: In order to overcome the shortcomings of the existing technology, this utility model provides a milling head segmentation angle detection mechanism.

[0004] Technical solution: A milling head segmentation angle detection mechanism, comprising: a drive shaft, a connecting piece, a bevel gear, an A-axis housing, a C-axis housing, a bearing, a rotating shaft, a flat key, an encoder, a coupling, and an encoder mount;

[0005] The drive shaft is fixedly mounted on the connector, and the connector is fixedly mounted on the A-axis housing via a bevel gear;

[0006] The drive shaft drives the rotating shaft to rotate via a flat key, and a bearing is fixedly mounted on the rotating shaft;

[0007] An encoder is fixedly mounted on the encoder mount, and the coupling connects the rotating shaft to the encoder.

[0008] As an optimization: the bearing, encoder housing, and rotating shaft are sequentially installed into the C-axis housing.

[0009] As an optimization: the A-axis housing is completely fitted into the C-axis housing.

[0010] As an optimization: the encoder and coupling are installed in the C-axis housing.

[0011] Beneficial effects: The encoder of the milling head segmentation angle detection mechanism of this utility model is directly connected to the A-axis housing and moves together. The rotation angle of the A-axis is the angle measured by the encoder. There is no gear backlash between the rotation angle of the milling head A-axis and the angle measured by the encoder, realizing the milling head one degree and one division function. This can improve the accuracy of detecting the segmentation of the milling shaft A-axis angle and reduce the measurement error. Attached Figure Description

[0013] Example

[0014] like Figure 1 As shown, a milling head segmentation angle detection mechanism includes: a drive shaft 1, a connector 2, a bevel gear 3, an A-axis housing 4, a C-axis housing 5, a bearing 6, a rotating shaft 7, a flat key 8, an encoder 9, a coupling 10, and an encoder base 11.

[0015] The drive shaft 1 is fixedly mounted on the connector 2, and the connector 2 is fixedly mounted on the A-axis housing 4 via a bevel gear 3. The drive shaft 1 drives the rotating shaft 7 to rotate via a flat key 8, and a bearing 6 is fixedly mounted on the rotating shaft 7. An encoder 9 is fixedly mounted on the encoder housing 11, and the coupling 10 connects the rotating shaft 7 and the encoder 9.

[0016] In this embodiment, the milling head segmentation angle detection mechanism is installed by first inserting the connector 2 into the A-axis housing 4 and fixing it to the A-axis housing 4; then, the drive shaft 1 is installed on the connector 2; next, the bearing 6, encoder seat 11, and rotating shaft 7 are sequentially inserted into the C-axis housing 5; then, the A-axis housing 4 is completely inserted into the C-axis housing 5, at which point the drive shaft 1 drives the rotating shaft 7 to rotate via the flat key 8; finally, the encoder 9 and coupling 10 are inserted into the C-axis housing 5, and the rotating shaft 7 is connected to the encoder 9 using the coupling 10. At this point, the rotation angle measured by the encoder 9 is the A-axis rotation angle, thus achieving accurate A-axis segmentation and realizing the milling head's one-degree-one-minute function.

[0017] The encoder of the milling head segmentation angle detection mechanism of this utility model is directly connected to the A-axis housing and moves together. The rotation angle of the A-axis is the angle measured by the encoder. There is no gear backlash between the rotation angle of the milling head A-axis and the angle measured by the encoder, realizing the milling head one degree and one division function. This can improve the accuracy of detecting the segmentation of the milling shaft A-axis angle and reduce the measurement error.
