Description

Technical Field

[0001] This invention belongs to the field of lens barrel processing technology, specifically referring to a grinding device for lens barrels. Background Technology

[0002] The microscope tube is a core component of optical equipment such as microscopes, telescopes, and cameras. The roughness, coaxiality, and roundness of its inner wall directly determine the imaging quality of the optical system. Currently, existing grinding devices for the inner wall of microscope tubes mostly adopt a "fixed clamping + single grinding" model. This means that the microscope tube is fixed using simple clamping components, and then a grinding mechanism is used to grind the inner wall of the tube at a uniform speed. The overall structure and operation method are relatively traditional, with many insurmountable technical defects that seriously affect the grinding quality and processing efficiency of the microscope tube, as detailed below: First, the adjustment precision is insufficient, and the fit is poor. Most existing grinding devices use conventional structures such as linear grooves or ordinary threaded adjustments for position adjustment between the clamping and grinding mechanisms. These methods have low adjustment precision and struggle to achieve accurate positioning of the clamping and grinding mechanisms based on the actual size and inner wall contour of the lens barrel. This results in the clamping mechanism failing to stably fit against the outer wall of the lens barrel, and the grinding mechanism failing to accurately fit against the inner wall. Uneven grinding is prone to occur during the grinding process, further affecting the grinding precision of the inner wall of the lens barrel and failing to meet the processing requirements of high-precision optical lens barrels. Furthermore, the cost is high. Inexpensive grinding machines cannot detect and identify rough areas on the inner wall of the lens barrel for targeted grinding. Most existing grinding devices can only perform uniform and even grinding of the entire inner wall of the lens barrel at a uniform speed. They lack the ability to detect and identify rough areas such as local protrusions on the inner wall of the lens barrel. For areas with obvious protrusions on the inner wall, targeted grinding is not possible. Instead, the entire inner wall must be repeatedly ground to compensate. This not only increases processing time and material consumption, but also makes it difficult to guarantee the grinding effect of the protruding areas. As a result, some lens barrels fail to meet standards due to local roughness on the inner wall, which seriously affects product quality. Summary of the Invention

[0003] In order to overcome the shortcomings of the prior art, the present invention provides a grinding device for lens barrels, which can automatically identify uneven areas on the inner wall of the lens barrel and grind them in a focused manner. At the same time, it is simple to operate and inexpensive.

[0004] The technical solution adopted by the present invention is as follows: The present invention provides a grinding device for lens barrel, including an outer tube, a clamping mechanism, an inner tube and a grinding mechanism. The inner tube is rotatably disposed inside the outer tube. The clamping mechanism is circumferentially arranged and slidably disposed on the top of the outer tube. The grinding mechanism is circumferentially arranged and slidably disposed on the top of the inner tube. The inner tube includes an adjusting cover and an inner tube. The adjusting cover is rotatably disposed on the top of the inner tube.

[0005] Furthermore, the outer cylinder includes a cylinder body, a sliding groove at the top of the cylinder body, an opening in the middle of the top wall of the cylinder body, an extension plate at the bottom of the opening, a slot in the inner wall of the opening and the extension plate, an annular groove inside the top wall of the cylinder body, a rotating ring rotatably disposed within the annular groove, an operating tooth at the bottom of the rotating ring, a vortex groove on the top wall of the rotating ring, a control knob rotatably disposed on one side wall of the cylinder body, a drive gear on the side of the control knob, the drive gear meshing with the operating tooth, an operating rod rotatably disposed on the bottom wall of the cylinder body, an operating handle of the operating rod located on the outside of the cylinder body, a bevel gear at the top of the operating rod, and a screw rotatably disposed at the bottom of the cylinder body, the handle at the top of the screw being detachable.

[0006] Further, the inner cylinder includes a second cylinder body, which is slidably disposed inside the opening. A retaining strip is provided on the outer wall of the second cylinder body, and the retaining strip is slidably disposed within a retaining groove. The adjusting cover includes a top cover, which is rotatably disposed on the top of the second cylinder body. A screw hole is provided at the center of the top cover. A second sliding groove is arranged in a circular array on the top wall of the top cover. The grinding mechanism is slidably disposed within the second sliding groove. The screw is threadedly engaged with the screw hole. An annular opening is provided at the top of the second cylinder body. An annular groove is provided on the bottom wall of the top cover. A rotating ring is rotatably disposed on the annular groove. The rotating ring includes a top ring and a connecting ring. The cylinder has a connecting plate and a bevel gear ring. The connecting plate is located at the bottom of the top ring, and the bevel gear ring is located at the bottom of the connecting plate. The top of the cylinder has a circumferential array of elastic telescopic rods. The bottom of the top ring has a rotating ring three, which is located at the top of the elastic telescopic rods. The top of the cylinder also has a friction ring two, which can generate electromagnetic force when energized. The bottom of the top ring also has a friction ring one, which is located above the friction ring two. The friction ring one is made of a magnetically attractive material. The top wall of the top ring has a vortex groove two. The bevel gear meshes with the bevel gear ring.

[0007] In the initial state, the elastic telescopic rod lifts the second rotating ring upwards via the top ring, separating the second rotating ring from the second cylinder. The second rotating ring is rotatable. When the second friction ring is energized, it generates a magnetic force and attracts the first friction ring through this magnetic force. The first friction ring and the second friction ring then come into contact, and friction fixes the second rotating ring to the second cylinder. Furthermore, the clamping mechanism is slidably disposed within the first groove. The clamping mechanism includes a slider, which is slidably disposed within the first groove. The bottom of the slider is provided with a locking tooth, which fits into the first vortex groove. The top of the slider is provided with an electric roller.

[0008] Furthermore, the polishing mechanism includes a second slider, a placement groove on the top of the second slider, a third slider that slides within the placement groove, a polishing roller on the top of the third slider, a pressure sensor between the third slider and the placement groove, and a second retaining tooth on the bottom of the second slider that engages with the second vortex groove.

[0009] The pressure sensor is connected to the friction ring via a signal connection.

[0010] The beneficial effects of the present invention using the above structure are as follows: This solution provides a grinding device for a lens barrel, in which the lens barrel wall is placed between a clamping mechanism and a grinding mechanism. The rotation of rotating rings one and two is adjusted by controlling knobs and operating levers. Rotating rings one and two adjust the positions of the grinding mechanism and the clamping mechanism via a vortex-shaped groove. The adjustment of the vortex-shaped groove is more precise, making the clamping mechanism and grinding mechanism fit closer to the lens barrel wall, thus improving processing accuracy. During processing, the electric roller of the clamping mechanism controls the rotation of the lens barrel. The inner grinding mechanism grinds the inner wall of the lens barrel through a grinding roller, and by rotating the screw, the inner barrel moves upward through the screw hole. If the inner wall of the lens barrel at the current height of the grinding mechanism bulges significantly, the inner wall of the lens barrel will squeeze the grinding roller, thereby activating the pressure sensor. When pressure is applied, the pressure sensor detects the electrical signal and controls the second friction ring to de-energize, causing the first friction ring to separate from the second friction ring. At this time, the top cover can rotate at the top of the inner cylinder. Continuing to rotate the screw will drive the top cover and the grinding mechanism on the top cover to rotate on the inner wall of the lens barrel, causing the grinding roller to continuously grind the inner wall of the lens barrel at the current height until the protrusions are smooth. After the pressure sensor loses pressure, the second friction ring is powered back on, and the first friction ring and the second friction ring re-adhere, thus fixing the top cover on the inner cylinder. The screw then drives the inner cylinder to move upward again. Compared with the traditional method, this method is simple to operate, has higher precision, and can also detect and identify rough parts on the inner wall of the lens barrel through a simple structure. It can also focus on grinding marked positions, which can effectively improve the grinding quality of the lens barrel. Attached Figure Description

[0021] Pressure sensor 605 is connected to friction ring 511 via signal connection.

[0022] In practical use, first adjust the screw 114 to lower the inner cylinder 3 to the bottom, so that the bevel gear 113 contacts the bevel gear ring 506. Then remove the handle of the screw 114, pass the lens barrel through the screw 114, and place the barrel wall between the clamping mechanism 2 and the grinding mechanism 6. Then, adjust the rotation of the rotating ring 107 and the rotating ring 503 by controlling the knob 110 and the operating lever 112. The rotating ring 107 and the rotating ring 503 adjust the position of the grinding mechanism 6 and the clamping mechanism 2 through the vortex groove. During the processing, the electric roller 203 of the clamping mechanism 2 is activated, thereby controlling the rotation of the lens barrel. The inner grinding mechanism 6 grinds the inner wall of the lens barrel through the grinding roller 606. Then, continue to rotate the screw 114, which drives the inner cylinder 3 to move upward through the screw hole 403. If the inner wall of the lens barrel at the current height of the grinding mechanism 6 is obviously bulging, the inner wall of the lens barrel will squeeze the grinding roller 606, thereby transmitting pressure. When pressure is applied by sensor 605, and after detecting the electrical signal, pressure sensor 605 controls friction ring 2 511 to de-energize. After de-energization, elastic telescopic rod 510 lifts rotating ring 2 503, causing friction ring 1 508 to separate from friction ring 2 511. At this time, top cover 401 can rotate at the top of inner cylinder 5. Continuing to rotate screw 114 will drive top cover 401 and the grinding mechanism 6 on top cover 401 to rotate on the inner wall of the lens barrel, so that grinding roller 606 continuously grinds the inner wall of the lens barrel at the current height until the protrusion is smooth. After pressure sensor 605 loses pressure, friction ring 2 511 is powered back on, friction ring 1 508 and friction ring 2 511 re-attach and fix, and the adjusting cover 4 is fixed on the inner cylinder 5 by the limiting position of grinding mechanism 6 on vortex groove 2 509. Screw 114 can once again drive inner cylinder 3 to move upward by rotation, and continue to grind the inner wall of the lens barrel until the processing is completed.
