DETAILED DESCRIPTION

[0019] The following is a further detailed description of the embodiments of the present invention in conjunction with the accompanying drawings, but the embodiments are not intended to limit the present invention. All similar structures and similar variations of the present invention should be included in the protection scope of the present invention.

[0020] like Figure 1 and Figure 2 As shown, a positioning and punching device for an optical axis comprises a workbench 1, on which a punching device 2 is provided, and on which slide rails 3 are provided at both ends of the workbench 1, on which an optical axis fixing device 5 is provided, and a punching table 4 is provided on the workbench 1 corresponding to the punching device 2. The two ends of the optical axis to be processed are fixed on the optical axis fixing device 5, and then the optical axis is moved to the position to be punched, and the punching device 2 punches holes therein, and then the optical axis is moved to the next position again for punching, until all holes of the optical axis are processed, and then the optical axis is removed.

[0021] For the specific structure of the optical axis fixing device 5, as shown in FIG. Figure 1 , Figure 2 and Figure 4 As shown, the optical axis fixing device 5 includes a fixing head 51, and at least two fixing columns 52 are provided at the front end of the fixing head 51, or as shown in FIG. Figure 4 There are three or more fixed columns 52 shown, and there are gaps between each fixed column 52. The fixed columns 52 are arc-shaped structures, and all the fixed columns 52 form a cylinder. The outer walls of all the fixed columns 52 form a continuous thread. A cylindrical accommodating cavity is formed between the fixed columns 52. The wall thickness of the fixed columns 52 gradually increases from the inside to the outside. The fixed columns 52 are connected to the locking ring 53 through threads. When in use, the end of the optical axis is inserted between the fixed columns 52, and then the locking ring 53 is tightened to fix it. The punching device 2 is set on the workbench 1 through the bracket 7, and the drill bit 21 on the output end of the punching device 2 is in a straight line with the center of the fixed column 52 of the optical axis fixing device 5.

[0022] Since the optical axis has various sizes, different sizes of optical axes need to be fixed using fixed columns 52 with different arcs and spacings. Therefore, in order to facilitate the replacement of the fixed head, a plug connector 54 is provided at the rear end of the fixed head 51. The plug connector 54 is in the shape of a polygonal column. Figure 4 The plug connector 54 shown is a rhombus-shaped cylinder, and of course it can also be a three-sided cylinder, a pentagonal cylinder or other stable shapes. Of course, it is best to be a regular polygonal cylinder that can ensure that its center of gravity is relatively stable. Correspondingly, the fixed head 51 is plugged into the mounting platform 55, and the mounting platform 55 is provided with a plug interface 56 corresponding to the plug connector 54; the mounting platform 55 is installed at the output end of the telescopic cylinder A57, and the telescopic cylinder A57 is fixed on the moving plate 58, and the moving plate 58 is installed on the slide rail 3 through the slider 59. Since the center heights of optical axes of different sizes are different, and the punching platform 4 is a fixed height, it is necessary to adjust the height of the optical axis so that the bottom of the optical axis can just rest on the punching platform 4. Of course, the height adjustment structure can also be achieved by adjusting the height of the plug connector or the plug interface of the fixed head.

[0023] In order to determine the punching position, a distance sensor is used to achieve positioning. Specifically, the optical axis fixing devices 5 at both ends are respectively the start and end. The optical axis fixing device 5 at the start is provided with a distance sensor transmitter 61, and the punching device 2 is correspondingly provided with a distance sensor receiver 62. The distance between one end of the optical axis and the punching device is monitored by the distance sensor generator, and the movement of the optical axis is driven by the pre-set punching position. Of course, the slider of the optical axis fixing device 5 is to be connected to the driving device to drive the movement of the optical axis.

[0024] In order to prevent the vibration of the optical axis from affecting the drilling accuracy, the brackets 7 on both sides of the drilling device 2 are respectively provided with positioning devices 8, and the positioning devices 8 include a telescopic cylinder B81 extending downward from the output end, and the output end of the telescopic cylinder B81 is provided with a crescent-shaped positioning platform 82, and an anti-skid layer can be provided on the positioning platform 82 to increase the friction between the optical axis; similarly, an anti-skid layer can also be added to the inner side of the fixing column 52. Figure 3 As shown, the punching platform 4 is provided with a receiving platform 41 corresponding to the drill bit 21 of the punching device 2, and the receiving platform 41 is provided with an avoidance opening 42 corresponding to the drill bit 21. The punching platforms 4 on both sides of the receiving platform 41 are respectively provided with rollers 43, and the receiving platform 41 and the rollers 43 are at the same height.

[0025] The distance sensor, telescopic cylinder, driving device, punching device, etc. mentioned in the present invention are all prior arts, so they are not described in detail here.

[0026] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
