Description

Technical Field

[0001] The utility model relates to the technical field of optical instrument production, in particular to a drilling device used in optical instrument production. Background Art

[0002] Drilling holes in optical instrument lens barrels involves creating threaded holes during the lens barrel production process to facilitate the later installation of lenses and other components. A fixture is required to secure the holes. Existing optical instrument lens barrels are often secured with a fixture during drilling. However, this fixture is difficult to rotate and adjust, resulting in drilling limited to one side.

[0003] A search revealed a patent with publication number CN220127654U, which discloses a drilling device for producing optical instrument lens barrels. The device, which is equipped with a first motor capable of driving the lens barrel body to rotate, eliminates the need to remove and reinstall the lens barrel body, thereby enabling the drilling mechanism to drill holes in the lens barrel body more quickly. Furthermore, the overall structure is relatively simple and convenient to use. However, the device has the following disadvantages: Because the drill bit and the first curved plate are fixed in position, alignment between the lens barrel center and the drill bit cannot be guaranteed when fixing lens barrels of different diameters. Consequently, the device can only drill holes for lens barrels of a single size, resulting in poor flexibility. Furthermore, the device has a small structural space for fixing the lens barrel, making it inconvenient to fix the lens barrel. Therefore, further improvements are needed. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to provide a drilling device for optical instrument production.

[0005] Material toggling mechanism, its both sides respectively have a cylinder pressure, and the cylinder pressure bar connects swing arm, and the swing arm end face has hook portion, and a bar passes position between the end of two swing arms and the hook portion.

[0020] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] like Figure 1-Figure 3 The figure shows a drilling device for optical instrument production, comprising a base plate 1, a plurality of support rods 2 are fixed on the side of the upper surface of the base plate 1, and the top ends of the plurality of support rods 2 are fixedly connected to a top plate 3, a servo motor 4 is fixed to one side of the lower surface of the base plate 1, the output shaft of the servo motor 4 passes through the base plate 1 and is fixedly connected to a support plate 5, and a slide groove 51 is provided on the upper surface of the support plate 5, and a positioning component 6 is provided inside the slide groove 51, a cylinder 7 is fixed on the upper surface of the top plate 3 and above the support plate 5, the telescopic end of the bottom of the cylinder 7 passes through the top plate 3 and is rotatably connected to a pressure plate 8, a linear motor 9 is vertically fixed to the side of the upper surface of the base plate 1 away from the support plate 5, an electric telescopic rod 10 is horizontally fixed to the moving end surface of the linear motor 9, and the telescopic end of the electric telescopic rod 10 is fixedly connected to a driving motor 11, and a plurality of drill rods 12 are matched with the driving motor 11, and each drill rod 12 end is fixedly connected to a connecting sleeve 121, and the output shaft of the driving motor 11 is fixed to a connecting block 111, and the connecting sleeve 121 can be fixedly sleeved on the surface of the connecting block 111.

[0022] The positioning assembly 6 includes two symmetrical slides 61 that are slidingly connected to the slide groove 51. The positioning assembly 6 also includes a bidirectional screw rod 62 located inside the slide groove 51, and the bidirectional screw rod 62 is rotatably connected to the inner wall of the slide groove 51 through a bearing. The bidirectional screw rod 62 passes through the two slides 61 and is threadedly connected to the slide groove 61. One end of the bidirectional screw rod 62 is fixedly connected to a handle 64.

[0023] When the bidirectional screw rod 62 is rotated by the handle 64, the bidirectional screw rod 62 drives the two slides 61 to move along the slide groove 51. The two slides 61 move in opposite directions. Therefore, by rotating the handle 64 forward or reverse, the two slides 61 can be moved closer or farther away from each other. Therefore, when installing the optical lens barrel, the optical lens barrel is placed outside the two slides 61, and then the handle 64 is rotated to drive the two slides 61 away from each other. The slides 61 are then pressed against the inner wall of the lens barrel to achieve the positioning of the lens barrel, ensuring that the lens barrel is centered on the upper surface of the support plate 5.

[0024] A rubber pad 63 is fixedly connected to the sides of the two slide plates 61 that are away from each other.

[0025] The rubber pad 63 can protect the inner wall of the lens barrel.

[0026] The pressure plate 8 is rotatably connected to the telescopic end of the cylinder 7 through a bearing.

[0027] Therefore, the cylinder 7 can not only drive the pressing plate 8 to move up and down, but also enable the pressing plate 8 to rotate at the bottom of the telescopic end of the cylinder 7.

[0028] Grooves 112 are provided on both sides of the connecting block 111 . A spring 113 is fixed to the inner wall of the groove 112 , and a clamping rod 114 is fixedly connected to the other end of the spring 113 . A clamping hole 122 for clamping the clamping rod 114 is provided on the side wall of the connecting sleeve 121 .

[0029] Therefore, when connecting the drill rod 12 to the output shaft of the drive motor 11, the clamping rod 114 on the connecting block 111 is first squeezed to retract the clamping rod 114 into the groove 112, and then the connecting sleeve 121 is sleeved on the surface of the connecting block 111. At this time, the spring 113 will squeeze the clamping rod 114 into the clamping hole 122, thereby achieving a fixed connection between the drill rod 12 and the output shaft of the drive motor 11. When replacing the drill rod 12, the clamping rod 114 is squeezed out of the clamping hole 122, and the connecting sleeve 121 can be removed from the surface of the connecting block 111 for replacement.

[0030] The diameter of each drill rod 12 is different. Different drill rods 12 can be used to drill holes in optical lens barrels of different sizes.

[0031] Working Principle: The lens barrel to be processed is placed on the upper surface of the support plate 5. Then, the handle 64 is turned to separate the two slides 61. The slides 61 are then aligned with the inner wall of the lens barrel to achieve the positioning of the lens barrel. The cylinder 7 is then activated to drive the pressure plate 8 downward, which is used to squeeze and fix the lens barrel. During drilling, the servo motor 4 can be activated to rotate the support plate 5, thereby changing the direction of the lens barrel. During drilling, the linear motor 9 drives the electric telescopic rod 10 to rise and fall, adjusting the height of the drill rod 12. After the height adjustment is completed, the drive motor 11 is activated to rotate the drill rod 12. The electric telescopic rod 10 is then extended to drive the drill rod 12 to move horizontally, completing the drilling of the lens barrel.
