[0018] In order to make the person skilled in the art better understand the utility model scheme, the technical scheme in the utility model embodiments will be described clearly and completely in combination with the drawings in the utility model embodiments below, and the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor should belong to the protection scope of the utility model.
[0019] In the technical scheme of the utility model, Figure 1 ,Figure 2 and Figure 3 is a structural schematic diagram provided according to the specific structure of the axis consistency adjusting mechanism, as shown in Figure 1 、 Figure 2 and Figure 3 , the utility model discloses:
[0020] The shell 4, the base 1, the first adjusting component 2 and the second adjusting component 3, the base 1 is connected with one end of the shell 4 by screw thread, the first adjusting component 2 and the second adjusting component 3 are arranged in the shell 4, one end of the first adjusting component 2 is in contact with the base 1, the other end of the first adjusting component 2 is in abutment with one end of the second adjusting component 3, the contact surface of the first adjusting component 2 and the second adjusting component 3 is inclined surface, the other end of the second adjusting component 3 is in contact with the other end of the shell 4, the contact surface of the second adjusting component 3 and the shell 4 is arc surface, the first adjusting component 2 and the second adjusting component 3 can rotate in the shell 4.
[0021] In an embodiment of the utility model, the shell 1, the base 1, the first adjusting component 2 and the second adjusting component 3 all are circular ring shape, the base 1.
[0022] In an embodiment of the utility model, the outer wall of the base 1 is provided with external thread, and the inner wall of the shell 4 is provided with internal thread.
[0023] In an embodiment of the utility model, the second adjusting component 3 and the base 1 are provided with screw holes, and screws are installed in the screw holes.
[0024] In an embodiment of the utility model, the base 1 is connected with the photoelectric collimator 5, and the second adjusting component 3 is connected with the mechanical plug shaft 6.
[0025] Wherein, the base 1 is the external adapter plate of the mechanism, and a mounting screw hole position is reserved. Its main function is to connect with external products and transmit the axis. At the same time, the first adjusting component 2 can be adjusted along the axis of the base 1, and the orientation of the space angle between the first adjusting component 2 and the second adjusting component 3 can be adjusted.
[0026] The first adjusting component 2 is an inclined cylindrical surface A, and the inclined surface is attached to the inclined surface of the second adjusting component 3. In order to reduce the influence of the flatness of the part processing process on the adjustment accuracy of the product, and to reduce the weight, a through hole can be processed in the middle of the inclined cylindrical surface A to form a circular ring.
[0027] The second adjusting component 3 is an inclined cylinder B, whose inclined surface fits into the inclined surface of inclined cylinder A. To reduce the impact of flatness during the part machining process on the product's adjustment accuracy, and for cost and weight reduction considerations, a through hole can be machined in the middle of the inclined cylinder B to form a ring shape. It also connects to external products, with pre-drilled holes for external mounting screws to transmit the axis.
[0028] The housing 4 is the outer shell of the entire mechanism, thus forming a locking handwheel. Its internal thread matches the external thread of the base 1. The contact surface between the second adjusting component 3 and the housing 4 is an arc surface. Specifically, the other end of the housing 4 is provided with an inner ball hole, and the other end of the second adjusting component 3 is spherical. The inner ball hole of the housing 4 and the ball head of the second adjusting component 3 have the same diameter.
[0029] Figure 5 is a photoelectric collimator. It is assumed that there is an angle α between the optical axis of the photoelectric collimator and the normal of the mounting end face. The mounting end face has a mounting threaded hole that matches the mounting hole position of serial number 1 and is fixedly connected.
[0030] In the attached diagram, reference numeral 6 indicates a mechanical insert shaft, assuming its mechanical axis is parallel to the normal of the mounting end face. The mounting end face has a threaded hole that matches the mounting hole of the second adjusting component 3 and is then fixedly connected.
[0031] The usage process of this utility model is as follows: The optical axis center of the photoelectric collimating lens 5 needs to be aligned parallel to the mechanical axis of the mechanical insertion shaft 6. During the adjustment process, the first adjusting component 2 remains stationary, while the second adjusting component 3 rotates along its axis, ensuring that its wedge-shaped surface is in contact with the wedge-shaped surface of the first adjusting component 2. Scales are marked between the first adjusting component 2 and the second adjusting component 3 for easy viewing of the rotation angle.
[0032] In this process, the axis of the second adjusting component 3 and the axis of the first adjusting component 2 form a spatial angle α, which is the same as the angle α between the optical axis of the photoelectric collimating lens 5 and the normal to the mounting end face. However, the orientation of this spatial angle is inconsistent with the orientation of the spatial angles of the two components whose axes need to be aligned, such as... Figure 4 As shown, at this time, the spatial angle between the first adjustment component 2 and the second adjustment component 3 is consistent with the direction of the angle α between the optical axis of the photoelectric collimator 5 and the normal of the mounting end face, resulting in an angle of 2α between the optical axis of the photoelectric collimator and the mechanical axis of the mechanical insertion shaft 6.
[0033] Treating the first adjusting component 2, the second adjusting component 3, and component 6 as a whole, simultaneously rotate them along the axis of the base 1. Adjust the spatial angle of the first adjusting component 2 and the second adjusting component 3 to align with the spatial angle of the two components whose axes require adjustment. Scales are marked between the first adjusting component 2 and the base 1 for easy viewing of the rotation angle. For example... Figure 5 As shown, at this time, the optical axis of the photoelectric collimating lens No. 5 coincides with the mechanical axis of No. 6, thus achieving the adjustment purpose.
[0034] Finally, it should be noted that the above specific embodiments are merely intended to illustrate the technical solutions of the present application and not to limit the present application. Although the present application has been described in detail with reference to the examples, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the present application, and all should be included in the scope of the claims of the present application.
