Description

A positioning and drilling device for optical axes Technical Field

[0001] This utility model relates to an optical axis processing device, specifically to an optical axis positioning and drilling device. Background Technology

[0002] Because of their smooth surface, optical axes require positioning during drilling. For example, Chinese Utility Model Patent CN211276609U describes a center drilling device for machining lead screw optical axes. This device includes a base with an arched seat fixed to its upper surface. Triangular openings are formed on the outer surfaces of both ends of the arched seat, within which an optical axis is slidably placed. Support plates are fixed to the outer surfaces of both sides of the arched seat, and a first cylinder is fixed to the support plates. A pressing block is fixed to the lower push rod of the first cylinder, and the pressing block has a trapezoidal notch that engages with the upper surface of the optical axis. While this device positions the lead screw optical axis only by placing it on the arched seat, multiple holes are typically drilled during the drilling process. This device cannot reposition the lead screw optical axis, and the lack of support at both ends allows for bending under the axis's own weight, affecting drilling accuracy. Technical issues

[0003] In view of the shortcomings of the existing technology, the technical problem to be solved by this utility model is how to provide a drilling device that can fix and position the optical axis, prevent displacement during the drilling process, and improve the drilling accuracy. Technical solutions

[0004] The technical solution of this utility model to solve the above-mentioned technical problems is: a positioning and drilling device for an optical axis, including a worktable, a drilling device on the worktable, slide rails on both ends of the worktable of the drilling device, an optical axis fixing device on the slide rails, and a drilling table on the worktable corresponding to the drilling device.

[0005] Furthermore, the optical axis fixing device includes a fixing head, the front end of which is provided with at least two fixing posts. The fixing posts are arc-shaped, and a cylindrical receiving cavity is formed between the fixing posts. The wall thickness of the fixing posts gradually increases from the inside to the outside, and the fixing posts are connected to a locking ring by threads.

[0006] Furthermore, the rear end of the fixing head is provided with a connector, which is in the shape of a polygonal column.

[0007] Furthermore, the fixing head is inserted into the mounting platform, and the mounting platform is provided with a corresponding insertion interface; the mounting platform is installed at the output end of the telescopic cylinder A, the telescopic cylinder A is fixed on the moving plate, and the moving plate is installed on the slide rail by a slider.

[0008] Furthermore, the optical axis fixing devices at both ends are the beginning and the end, respectively. The optical axis fixing device at the beginning is equipped with a distance sensor transmitter, and the drilling device is equipped with a distance sensor receiver.

[0009] Furthermore, the drilling device is mounted on the workbench via a bracket, and the drill bit on the output end of the drilling device is aligned with the center of the fixing column of the optical axis fixing device.

[0010] Furthermore, positioning devices are respectively provided on the brackets on both sides of the drilling device. The positioning device includes a telescopic cylinder B with its output end extending downward, and the output end of the telescopic cylinder B is provided with a crescent-shaped positioning platform.

[0011] Furthermore, the drilling platform is provided with a receiving platform corresponding to the drill bit of the drilling device, and the receiving platform is provided with a clearance opening corresponding to the drill bit.

[0012] Furthermore, rollers are respectively provided on the punching platforms on both sides of the receiving platform, and the receiving platform and the rollers are at the same height. Beneficial effects

[0013] The advantages of this invention compared to existing technologies are as follows: The optical axis positioning and drilling device of this invention uses optical axis fixing devices on both sides to fix and position the optical axis for movement; the three-section support of the optical axis fixing device and the drilling table keeps the optical axis in a straight state, and the positioning table fixes the optical axis near the drilling device to prevent the optical axis from shifting during the drilling process, thus improving drilling accuracy.

The best embodiment of the present invention

[0019] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings. However, the embodiments are not intended to limit the present invention. Any similar structures and similar variations of the present invention should be included in the protection scope of the present invention.

[0020] As shown in Figures 1 and 2, a positioning and drilling device for an optical axis includes a worktable 1, on which a drilling device 2 is mounted. Slide rails 3 are mounted on both ends of the worktable 1 of the drilling device 2, and optical axis fixing devices 5 are mounted on the slide rails 3. A drilling table 4 is mounted on the worktable 1 corresponding to the drilling device 2. The two ends of the optical axis to be processed are fixed to the optical axis fixing devices 5. Then, the optical axis is moved to the position to be drilled, and the drilling device 2 drills holes in it. The optical axis is then moved to the next position for drilling again, until all holes in the optical axis are processed, and then the optical axis is removed.

[0021] The specific structure of the optical axis fixing device 5 is shown in Figures 1, 2, and 4. The optical axis fixing device 5 includes a fixing head 51. The front end of the fixing head 51 has at least two fixing posts 52, or three or more as shown in Figure 4. There are gaps between each fixing post 52. Each fixing post 52 has an arc-shaped structure, and all fixing posts 52 form a cylinder. The outer walls of all fixing posts 52 form a continuous thread. A cylindrical receiving cavity is formed between the fixing posts 52. The wall thickness of each fixing post 52 gradually increases from the inside out. Each fixing post 52 is connected to a locking ring 53 via threads. In use, the end of the optical axis is inserted between the fixing posts 52, and then the locking ring 53 is tightened to fix it. The drilling device 2 is mounted on the worktable 1 via a bracket 7. The drill bit 21 on the output end of the drilling device 2 is aligned with the center of the fixing posts 52 of the optical axis fixing device 5.

[0022] Since optical axes come in various sizes, fixing posts 52 with different spacing and curvature are required for fixing optical axes of different sizes. Therefore, to facilitate the replacement of the fixing head, the rear end of the fixing head 51 is provided with a connector 54, which is a polygonal prism. As shown in Figure 4, the connector 54 is a rhomboid prism, but it can also be a triangular prism, a pentagonal prism, or other stable shapes. Of course, it is best to be a regular polygonal prism that can ensure a relatively stable center of gravity. Correspondingly, the fixing head 51 is inserted into the mounting platform 55, and the mounting platform 55 is provided with a connector 56 corresponding to the connector 54. The mounting platform 55 is installed at the output end of the telescopic cylinder A57, which is fixed on the moving plate 58. The moving plate 58 is installed on the slide rail 3 via a slider 59. Since the center height of optical axes of different sizes is different, while the drilling platform 4 has a fixed height, the height of the optical axis needs to be adjusted so that the bottom of the optical axis can just rest on the drilling platform 4. Of course, the height of the structure can also be adjusted by adjusting the height of the plug or connector of the fixing head.

[0023] To determine the drilling position, a distance sensor is used for positioning. Specifically, the optical axis fixing devices 5 at both ends are the opening and the closing ends, respectively. The opening optical axis fixing device 5 is equipped with a distance sensor transmitter 61, and the drilling device 2 is equipped with a corresponding distance sensor receiver 62. The distance sensor transmitter monitors the distance between one end of the optical axis and the drilling device, and the optical axis is driven to move according to the pre-set drilling position. Of course, the slider of the optical axis fixing device 5 is connected to the driving device to drive the movement of the optical axis.

[0024] To prevent vibration from affecting drilling accuracy during optical axis drilling, positioning devices 8 are respectively provided on the supports 7 on both sides of the drilling device 2. Each positioning device 8 includes a telescopic cylinder B81 with its output end extending downwards. The output end of the telescopic cylinder B81 is provided with a crescent-shaped positioning platform 82. An anti-slip layer can be provided on the positioning platform 82 to increase friction with the optical axis. Similarly, an anti-slip layer can also be added to the inner side of the fixing column 52. As shown in Figure 3, the drilling platform 4 is provided with a receiving platform 41 corresponding to the drill bit 21 of the drilling device 2. An avoidance opening 42 is provided on the receiving platform 41 corresponding to the drill bit 21. Rollers 43 are respectively provided on the drilling platforms 4 on both sides of the receiving platform 41, and the heights of the receiving platform 41 and the rollers 43 are the same.

[0025] The distance sensor, telescopic cylinder, drive device, and drilling device mentioned in this utility model are all existing technologies, so they are not described in detail here.

[0026] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
