Description

Technical Field

[0001] The utility model relates to the technical field of lens processing, in particular to an angle adjustment device for processing a conical lens. Background Art

[0002] A conical lens is a circular cone lens, also commonly known as an axisymmetric prism. It is a lens with a conical surface and a flat surface. Conical lenses are often used to generate beams with a Bessel function-type intensity distribution or a conical non-divergent beam. Conical lenses are polished during processing to remove metal scratches and irregularities on the surface of the mirror, improve the overall smoothness and further reduce breakage. During processing, they are fixed by an angle adjustment device to facilitate polishing.

[0003] After searching, a utility model with Chinese patent publication number CN209140572U discloses an adjustable lens grinding and clamping device, including a grinding table, on which a support column and a hydraulic rod are respectively arranged, and the support column and the hydraulic rod are arranged in parallel, one end of the support column and the hydraulic rod are respectively vertically welded to the surface of the grinding table, and a mounting plate is vertically welded to the end of the support column away from the grinding table, and a clamping plate is vertically welded to the end of the hydraulic rod away from the grinding table.

[0004] Although the above device can adjust the height of the fixed lens, due to the special structure of the conical lens, the grinding of the conical surface needs to be adjusted again. The grinding head of the grinder is difficult to fit the conical surface, which is inconvenient to use and has limitations. Utility Model Content

The angle of the conical lens is changed by adjusting the component, and the electric telescopic rod on the top of the mounting plate is started.

[0009] As a further preferred embodiment of the present technical solution, a handle is coaxially fixed to the outer wall of one end of the rotating shaft of the mounting frame, and the rotating radius of the handle is larger than the radius of the rotating shaft of the mounting frame.

[0010] As a further preferred embodiment of the present technical solution, the fixing assembly includes a same bidirectional screw rod rotatably connected to the inner walls on both sides of the mounting frame, and a fixing plate is threadedly connected to the threads at both ends of the bidirectional screw rod, and the two fixing plates are symmetrically arranged.

[0011] As a further preferred embodiment of the present technical solution, a motor is fixedly mounted on an outer wall of one side of the mounting frame, and an output end of the motor and one end of the bidirectional lead screw are coaxially fixed.

[0012] Place the conical lens between the two fixed plates, then start the motor, which will drive the bidirectional screw to rotate inside the mounting frame. The two fixed plates restricted by the limit grooves can be driven by the bidirectional screw to approach each other, and then the conical lens can be fixed in the middle position by the two fixed plates.

[0014] As a further preferred embodiment of the present technical solution, the threads at both ends of the bidirectional screw have the same parameters except for the opposite rotation directions, and the thread lead angles of the two thread lines are smaller than the equivalent friction angle.

[0015] The utility model provides an angle adjustment device for processing a conical lens, which has the following features:

[0016] Beneficial effects:

[0017] (1) The utility model can adjust the overall inclination of the lens according to the angle of the lens bevel by setting an adjustment component, so that the grinding head of the external grinder can just fit the outer wall of the lens, which is beneficial to improving the processing effect. The angle of the conical lens is changed by adjusting the component, and the electric telescopic rod on the top of the mounting plate is started.

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0025] The utility model provides a technical solution: Figure 1 , Figure 2 and Figure 3As shown, in this embodiment, an angle adjustment device for processing a conical lens includes a mounting plate 1, which is characterized in that: a vertical plate 2 is fixedly connected to one side of the top outer wall of the mounting plate 1, an adjustment component 6 is installed on the top of the vertical plate 2, the adjustment component 6 includes a connecting shaft 601 rotatably connected to the outer wall of one side of the vertical plate 2, and the connecting shaft 601 is arranged to penetrate the vertical plate 2, a gear ring 602 is fixedly sleeved on one side of the circumferential outer wall of the connecting shaft 601, an electric telescopic rod 604 is fixedly installed on one side of the top outer wall of the mounting plate 1, and a vertically arranged rack 603 is fixedly connected to the output end of the electric telescopic rod 604, the rack 603 and the gear ring 602 are meshed, and one end of the connecting shaft 601 is fixedly connected to the connecting frame 3.

[0026] By adjusting the component 6 to change the angle of the conical lens, the electric telescopic rod 604 on the top of the mounting plate 1 is started, and the output end of the electric telescopic rod 604 drives the rack 603 to move up or down. Since the gear ring 602 and the rack 603 are meshed, the rack 603 can drive the connecting shaft 601 to rotate through the gear ring 602, and the connecting shaft 601 will drive the connecting frame 3 to flip, and the fixing component 7 and the conical lens will flip synchronously with the connecting frame 3, ensuring that the processing process of the conical lens is more convenient.

[0027] like Figure 1 As shown, the inner wall of one end of the connecting frame 3 is rotatably connected to the mounting frame 4, and a fixing component 7 is installed inside the mounting frame 4.

[0028] A handle 5 is coaxially fixed to the outer wall of one end of the rotating shaft of the mounting frame 4. The rotating radius of the handle 5 is larger than the rotating shaft radius of the mounting frame 4, which can increase the transmission force arm and make the driving process easier.

[0029] The handle 5 can also drive the mounting frame 4 to rotate at one end of the connecting frame 3, and then the conical lens will also rotate accordingly, so as to ensure that the processing of the lens is comprehensive enough.

[0030] like Figure 2 and Figure 4 As shown, the fixing assembly 7 includes the same bidirectional screw rod 703 which is rotatably connected to the inner walls on both sides of the mounting frame 4, and a fixing plate 702 is threadedly connected to the threads at both ends of the bidirectional screw rod 703. The two fixing plates 702 are symmetrically arranged, and a limiting groove 701 is provided on the inner wall at one end of the mounting frame 4, and one end of the two fixing plates 702 are slidably connected in the limiting groove 701.

[0031] A motor 704 is fixedly mounted on the outer wall of one side of the mounting frame 4 , and the output end of the motor 704 and one end of the bidirectional lead screw 703 are coaxially fixed.

[0032] Place the conical lens between the two fixing plates 702, then start the motor 704, which will drive the bidirectional screw 703 to rotate inside the mounting frame 4. The two fixing plates 702 restricted by the limiting grooves 701 can be driven by the bidirectional screw 703 to approach each other, and then the conical lens can be fixed in the middle position by the two fixing plates 702.

[0033] like Figure 1 and Figure 2 As shown, the outer walls of the two fixing plates 702 close to each other are both provided with a plurality of anti-slip strips 705 , which is helpful to increase the fixing effect of the fixing assembly 7 .

[0034] like Figure 1 and Figure 2 As shown, the threads at both ends of the bidirectional screw 703 have the same parameters except for the opposite rotation directions, and the thread lead angles of the two thread lines are smaller than the equivalent friction angle, so that the two fixed plates 702 can be driven to move synchronously and ensure that the bidirectional screw 703 has a self-locking property.

[0035] The utility model provides an angle adjustment device for processing a conical lens, and the specific working principle is as follows:

[0036] When the device is working, the conical lens is placed between the two fixing plates 702, and then the motor 704 is started. The motor 704 will drive the bidirectional screw rod 703 to rotate inside the mounting frame 4, and the two fixing plates 702 limited by the limiting groove 701 can be driven by the bidirectional screw rod 703 to approach each other, and then the conical lens can be fixed in the middle position by the two fixing plates 702, and then the angle of the conical lens is changed by adjusting the component 6, and the electric telescopic rod 604 on the top of the mounting plate 1 is started. The output end of the electric telescopic rod 604 drives the rack 603 to move up or down. Since the gear ring 602 and the rack 603 are meshed, the rack 603 can drive the connecting shaft 601 to rotate through the gear ring 602, and the connecting shaft 601 will drive the connecting frame 3 to flip, and the fixing component 7 and the conical lens will flip synchronously with the connecting frame 3, ensuring that the processing process of the conical lens is more convenient, and the mounting frame 4 can also be driven to rotate at one end of the connecting frame 3 through the handle 5, and then the conical lens will also rotate accordingly, which can ensure that the processing of the lens is comprehensive enough.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
