Description

Technical Field

[0001] This invention relates to the field of optical lens technology, and in particular to a displacement adjustment structure for an optical lens. Background Technology

[0002] Currently, magnifying glasses are among the most commonly used optical lenses. They are simple visual optical devices often used to observe tiny details of objects. They are converging lenses with a focal length much smaller than the eye's visual distance. The size of the image formed on the human retina is proportional to the angle subtended by the object at the eye. When visually inspecting small parts, the parts are often placed on the surface of a machine equipped with a magnifying glass to facilitate magnified observation of the small parts.

[0003] According to patent (publication number "CN217506269U"), a displacement adjustment structure for an optical lens belongs to the field of optical lens technology. The structure includes a base, a lead screw rotatably connected to the edge of the upper surface of the base, a circular plate fixedly connected to the outer wall of the lead screw, and a protrusion integrally formed on the outer wall of the circular plate, with multiple protrusions arranged in a ring. Slide rails are symmetrically fixedly connected to both sides of the lead screw, and a metal ring is fixedly connected to the top of the slide rails. A rubber ring is embedded in the inner wall of the metal ring, and the rubber ring abuts against the protrusion. A groove is formed on the surface of the slide rail corresponding to the lead screw. A slider is provided below the metal ring, and the slider is screwed to the lead screw. This structure allows for adjustment of the magnifying glass height via a precision screw, which is beneficial for focusing the magnifying glass and improves focusing accuracy. Furthermore, the structure for horizontally adjusting the magnifying glass is simple, easy to operate, and reduces manufacturing costs.

[0004] However, current magnifying glass machines only allow for vertical or horizontal adjustment of the magnifying glass's position. When using these machines, operators may need to observe different parts of the workpiece from multiple directions and angles based on their observation habits. The limited adjustment range of the aforementioned structures affects the accuracy of workpiece inspection. Therefore, we propose an optical lens displacement adjustment structure. Utility Model Content

[0005] The main objective of this invention is to provide a displacement adjustment structure for an optical lens, which can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An optical lens displacement adjustment structure includes a mounting platform, a placement platform fixedly mounted on the top side of the mounting platform, a sliding plate slidably mounted on the top side of the mounting platform, a support plate vertically fixedly mounted on the top of the sliding plate, a steering mechanism provided on the top side of the support plate, a rotation mechanism provided at the bottom of the steering mechanism, a magnifying lens fixedly mounted on the side of the rotation mechanism, an electric actuator vertically fixedly mounted on the top side of the sliding plate, a transmission plate slidably mounted on the top side of the support plate, and the top of the electric actuator's transmission shaft and the middle of the bottom of the transmission plate are fixedly connected, and a drive mechanism is provided at the bottom of the mounting platform, and the drive mechanism is drively connected to the sliding plate.

[0007] As an optional solution to the technical solution of this application, the steering mechanism includes a transmission rack and a transmission rack. The transmission rack is slidably installed on the top side of the support plate, and the side of the transmission rack is fixedly connected to the side of the transmission plate. A sliding frame is slidably sleeved on the outer side of the transmission rack. A rotating rod is vertically rotatably installed on the middle of the inner side of the sliding frame through a bearing. A transmission gear is fixedly sleeved on the middle of the outer side of the rotating rod, and the outer side of the transmission gear meshes with the outer side of the transmission rack. A servo motor is fixedly installed on the top outer side of the sliding frame, and the bottom of the servo motor transmission shaft is fixedly connected to the top of the rotating rod through a coupling. Guide sliders are fixedly installed on both ends of the inner side of the sliding frame. Guide grooves are opened on both sides of the outer side of the transmission rack, and the guide sliders are slidably installed inside the guide grooves.

[0008] By adopting the above technical solution, the transmission rack and gear meshing action allows the transmission gear to drive the sliding frame to rotate synchronously on the outside of the transmission rack, which in turn drives the magnifying lens set on the outside of the sliding frame to rotate synchronously on the top of the placement stage, thereby adjusting the magnification position.

[0009] As an optional solution to the technical solution of this application, the rotating mechanism includes a hollow tube and a fixed rod. An installation block is fixedly installed at the bottom of the sliding frame, and a hollow tube is fixedly installed at the middle of the side of the installation block. A fixed rod is rotatably inserted into the hollow tube, and the top of the side of the fixed rod is fixedly connected to the outside of the magnifying lens. Limit screw holes are opened on both sides of the outside of the fixed rod. Insertion holes are opened on the side of the hollow tube, and there are several sets of insertion holes. A tightening bolt is slidably inserted through the insertion hole, and the top of the side of the tightening bolt is screwed into the limit screw hole by a thread.

[0010] By adopting the above technical solution, the magnifying lens can be rotated around the fixed rod by inserting the fixing rod into the inner wall of the hollow tube and by passing the tightening bolt through the insertion hole and screwing it into the limiting screw hole.

[0011] As an optional solution to the technical solution of this application, the driving mechanism includes a transmission rod, a rotating motor is fixedly installed at the bottom center of the mounting platform, a connecting rod is fixedly installed at the bottom of the transmission shaft of the rotating motor, a transmission rod is fixedly sleeved on the outer bottom of the connecting rod, a movable plate is slidably installed on the bottom side of the mounting platform, and the top of the movable plate and the bottom of the sliding plate are fixedly connected, an installation rod is vertically fixedly installed at the bottom center of the movable plate, and the top of the side of the transmission rod is rotatably sleeved on the outer wall of the installation rod through a bearing, and a sliding groove is opened inside the mounting platform.

[0012] By adopting the above technical solution, driven by the rotating motor and connected by the transmission rod, the sliding plate, the transmission rack and magnifying lens on its top can be further rotated, increasing the adjustment range of the magnifying lens and improving the magnification accuracy of the workpiece.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. The present application discloses a displacement adjustment structure for an optical lens. A transmission rack is installed on the top of the mounting platform, and a sliding frame is slidably sleeved on the outside of the transmission rack. When the servo motor is running, it drives a connected rotating rod and transmission gear to rotate. The meshing transmission action of the rotating rod and transmission rack causes the transmission gear to drive the sliding frame to rotate synchronously on the outside of the transmission rack. This, in turn, causes the magnifying lens mounted on the outside of the sliding frame to rotate synchronously on the top of the mounting platform, thereby adjusting the magnification position. Furthermore, by inserting a fixing rod into a hollow tube, and by rotating the fixing rod inside the hollow tube and adjusting the tightening bolts inserted into different insertion holes, the magnifying lens can rotate around the fixing rod as the center. This allows for convenient adjustment of the observation angle position according to the user's needs, improving the adjustment range of the magnifying lens.

[0014] 2. The displacement adjustment structure of an optical lens according to the technical solution of this application is provided with a transmission rod at the bottom of the mounting platform, and the side end of the transmission rod is connected to the connecting rod, and the other side of the transmission rod is rotatably connected to the outer wall of the fixed rod. When the rotating motor is running, it can drive the sliding plate to rotate synchronously on the top surface of the mounting platform through the transmission rod. This can further drive the sliding plate, the transmission rack on its top, and the magnifying lens to rotate, thereby increasing the adjustment range of the magnifying lens and improving the magnification accuracy of the magnifying lens for workpiece inspection.

[0018] In this technical solution (through Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown), a transmission rack 24 is slidably mounted on the top side of the support plate 22, and the side of the transmission rack 24 is fixedly connected to the side of the transmission plate 23. A sliding frame 25 is slidably sleeved on the outer side of the transmission rack 24. A rotating rod 27 is vertically rotatably mounted on the middle of the inner side of the sliding frame 25 through a bearing. A transmission gear 28 is fixedly sleeved on the middle of the outer side of the rotating rod 27, and the outer side of the transmission gear 28 meshes with the outer side of the transmission rack 24. A servo motor 26 is fixedly mounted on the top outer side of the sliding frame 25, and the bottom of the transmission shaft of the servo motor 26 is fixedly connected to the top of the rotating rod 27 through a coupling.

[0019] In this technical solution (through Figure 1 , Figure 2 , Figure 3 and Figure 4As shown), guide sliders 4 are fixedly installed at both ends of the inner side of the sliding frame 25, and guide grooves 41 are opened on both sides of the outer side of the transmission rack 24. The guide sliders 4 are slidably installed inside the guide grooves 41. The vertical cross-sections of the guide sliders 4 and the guide grooves 41 are both inverted T-shaped.

[0020] In this technical solution (through Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown), a mounting block 3 is fixedly installed at the bottom of the sliding frame 25, and a hollow tube 31 is fixedly installed at the middle of the side of the mounting block 3. A fixing rod 32 is rotatably inserted into the hollow tube 31, and the top of the side of the fixing rod 32 is fixedly connected to the outside of the magnifying lens 33. Limit screw holes 35 are opened on both sides of the outside of the fixing rod 32. Insertion holes 34 are opened on the side of the hollow tube 31, and there are several sets of insertion holes 34. A tightening bolt 36 is slidably inserted through the insertion hole 34, and the top of the side of the tightening bolt 36 is screwed into the limit screw hole 35 by thread.

[0021] In some technical solutions (through Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown), a rotating motor 42 is fixedly installed at the bottom center of the mounting platform 1.

[0022] During operation, the workpiece requiring magnification and inspection is placed on the surface of the placement table 11. The inspector, based on their inspection habits and the desired inspection location on the workpiece surface, activates the electric actuator 21. This movement causes the transmission plate 23 to move vertically outside the support plate 22, simultaneously moving the transmission rack 24 and the magnifying lens 33 connected to its side vertically. After adjusting the vertical height of the magnifying lens 33 to a suitable position, the servo motor 26 is activated, causing the rotating rod 27 and transmission gear 28 to rotate synchronously.

Adjust the tilt angle of the magnifying lens 33 so that it can be adjusted to a suitable position according to the inspection personnel's visual habits. Then, pass the bolt 36 through the corresponding insertion hole 34 and screw it into the limiting screw hole 35 to fix the position of the magnifying lens 33. When the adjustment range of the transmission rack 24 is limited, the operator can turn on the rotating motor 42 through an external control switch. After it starts running, under the transmission action of the transmission rod 44, it can drive the movable plate 45 and the sliding plate 2 to move synchronously, adjust the horizontal position of the transmission rack 24 and the magnifying lens 33, and then use the magnifying lens 33 to visually magnify the surface of the workpiece.
