Description

Technical Field

[0001] This utility model relates to the field of objective lens grinding technology, specifically to a grinding tool for grinding optical objectives. Background Technology

[0002] In the field of optics, the fine grinding process of optical objectives plays a crucial role in ensuring the imaging quality and performance of optical equipment. However, the traditional fine grinding process of optical objectives still has many problems.

[0003] With the continuous development of optical technology, traditional fine grinding tools are unable to meet diverse needs. Their functions are limited and they cannot complete the multi-stage processing from rough grinding to fine grinding on a single device. They often need to rely on multiple different types of grinding tools to operate in sequence, which undoubtedly further increases the complexity of the production process and the cost.

[0004] Furthermore, the existing grinding tools are quite cumbersome to change the grinding head when fine grinding optical lenses. In the past, when different grinding heads were needed to be switched at different fine grinding stages, manual disassembly and installation were often required. This process not only consumed a lot of time, but was also prone to errors due to improper operation, which affected production efficiency and increased production costs.

[0005] Therefore, we propose a grinding tool for fine grinding of optical objectives to solve the problems mentioned above. Utility Model Content

[0006] 1. The technical problem to be solved by the utility model:

[0007] The purpose of this invention is to provide a grinding tool for fine grinding of optical objectives, so as to solve the problems currently found in the market as mentioned in the background art.

[0008] 2. Technical Solution:

[0009] To achieve the above objectives, the present invention provides the following technical solution: a grinding tool for fine grinding of optical objectives, comprising a frame, an optical objective support seat mounted on the upper front side of the frame, and a linear motion module fixed on the upper rear side of the frame, and a drive mechanism mounted on the output end of the linear motion module;

[0010] A bracket is installed on the upper front side of the frame, and a rotating mechanism is installed on the bracket. A grinding wheel switching module is installed at the output end of the rotating mechanism. The grinding wheel switching module includes a turntable, and several mounting sleeves are installed on the turntable through bearings. A fine grinding head is placed inside the mounting sleeve. The drive mechanism performs fine grinding on the objective lens through the fine grinding head.

[0011] Furthermore, the drive mechanism includes a movable seat mounted on the output end of the linear motion module, a motor mounted on the movable seat, and a connector mounted on the output end of the motor.

[0012] The above technical solution enables the motor to rotate the connector after it starts.

[0013] Furthermore, the rotating mechanism includes a dial and a grooved disc mounted on a bracket via bearings, the dial and the grooved disc forming a grooved wheel structure.

[0014] The above technical solution enables the existing drive device to rotate the dial, and the grooved wheel structure to drive the grooved disc to rotate intermittently.

[0015] Furthermore, the mounting sleeve includes a rotating ring mounted on a turntable via a bearing. Inside the rotating ring, a circular ring is elastically slidably mounted up and down via an elastic element. The elastic element includes several columns fixedly mounted at the lower end of the circular ring. The columns are slidably mounted up and down inside the rotating ring. A pressure spring is sleeved on the outer side of the column, and the two ends of the pressure spring are respectively connected to the rotating ring and the circular ring.

[0016] The above technical solution enables the grinding head to rotate with the connector, thereby reducing friction on the turntable by using the mounting sleeve. At the same time, under the action of the elastic element, the grinding head can continuously move downward, ensuring the grinding effect.

[0017] Furthermore, several of the mounting sleeves are distributed at equal angles about the center of the turntable.

[0018] The above technical solution allows for the placement of multiple fine grinding heads, including those with different mesh sizes.

[0019] Furthermore, the interior of the fine grinding head is provided with a connecting groove that mates with the connecting head. The connecting groove is a rectangle with rounded ends. The outer diameter of the upper end of the fine grinding head is larger than the inner diameter of the ring, and the outer diameter of the lower end of the fine grinding head is equal to the inner diameter of the ring.

[0020] The above technical solution allows the fine grinding head to be placed inside the mounting sleeve, and the connector can drive the fine grinding head to rotate and grind through the connecting groove.

[0021] 3. Beneficial effects:

[0022] Compared with the prior art, the grinding wheel for fine grinding of optical objectives of this utility model places several grinding heads on a turntable, which allows for quick switching between different grinding heads, reducing the time cost of changing grinding wheels, and meeting the fine grinding requirements of optical objectives. The specific details are as follows:

[0023] The design of the rotating mechanism's grooved wheel structure and turntable allows for convenient and quick switching between different fine grinding heads, improving work efficiency and reducing the time cost of changing grinding tools. It is suitable for processing needs of different fine grinding stages or different types of optical lenses. Subsequently, the motor cooperates with the connecting groove of the fine grinding head through the connector, which can reliably transmit power and ensure the stable rotation of the fine grinding head, providing a stable power source for fine grinding operations.

[0024] By installing a mounting sleeve on the outside of the fine grinding head, when the motor drives the fine grinding head to rotate through the convex-concave fit between the connector and the connecting groove, the bearing connection between the mounting sleeve and the turntable reduces the frictional impact of the fine grinding head rotation on the turntable. At the same time, the setting of the elastic element allows the fine grinding head to continuously grind the optical objective lens as the drive mechanism moves downward, ensuring the fine grinding effect.

[0036] Please see Figure 1-6 An optical objective lens grinding tool includes a frame 1, an optical objective lens support 2 mounted on the upper front side of the frame 1, and a linear motion module 3 fixed on the upper rear side of the frame 1. A drive mechanism 4 is mounted on the output end of the linear motion module 3. The drive mechanism 4 includes a movable seat 41 mounted on the output end of the linear motion module 3, a motor 42 mounted on the movable seat 41, and a connector 43 mounted on the output end of the motor 42. A connecting groove 81 that mates with the connector 43 is provided inside the grinding head 8. The connecting groove 81 is a rectangle with rounded ends.

[0037] Start the linear motion module 3, which drives the connector 43 to extend into the connecting groove 81. Start the motor 42, and through the cooperation between the connector 43 and the connecting groove 81 of the fine grinding head 8, reliably transmit power, ensuring the stable rotation of the fine grinding head 8 and providing a stable power source for the fine grinding operation.

[0038] A bracket 11 is mounted on the upper front side of the frame 1. A rotating mechanism 5 is mounted on the bracket 11, and a grinding tool switching module is mounted on the output end of the rotating mechanism 5. The grinding tool switching module includes a turntable 6, on which several mounting sleeves 7 are mounted via bearings. A fine grinding head 8 is placed inside the mounting sleeve 7, and the drive mechanism 4 performs fine grinding on the objective lens through the fine grinding head 8. The rotating mechanism 5 includes a dial 51 and a grooved plate 52 mounted on the bracket 11 via bearings. The dial 51 and the grooved plate 52 form a grooved wheel structure. The mounting sleeve 7 includes a rotating ring 71 mounted on the turntable 6 via bearings. Inside the ring 71, a circular ring 72 is elastically and slidably mounted up and down via an elastic element 73. The elastic element 73 includes several columns 731 fixedly mounted at the lower end of the circular ring 72. The columns 731 are slidably mounted up and down inside the rotating ring 71. A pressure spring 732 is sleeved on the outer side of the column 731. The two ends of the pressure spring 732 are respectively connected to the rotating ring 71 and the circular ring 72. Several mounting sleeves 7 are distributed at equal angles about the center of the turntable 6. The outer diameter of the upper end of the fine grinding head 8 is larger than the inner diameter of the circular ring 72, and the outer diameter of the lower end of the fine grinding head 8 is equal to the inner diameter of the circular ring 72.

[0039] First, place several fine grinding heads 8 into several mounting sleeves 7. Then, start the drive device at the end of the dial 51 to drive the dial 51 to rotate. Utilize the grooved wheel structure between the dial 51 and the grooved plate 52 to drive the turntable 6 to rotate intermittently, so as to quickly switch between different fine grinding heads 8, improve work efficiency, and reduce the time cost of changing grinding tools.

[0040] When the drive mechanism 4 drives the fine grinding head 8 to rotate, the bearing connection between the mounting sleeve 7 and the turntable 6 reduces the frictional impact on the turntable 6 caused by the rotation of the fine grinding head 8. At the same time, the elastic element 73 allows the fine grinding head 8 to continuously grind the optical objective lens as the drive mechanism 4 moves downward, ensuring the fine grinding effect.

[0041] When several fine grinding heads 8 are set with different grit sizes, the grinding wheel can complete multiple processing stages from rough grinding to fine grinding on one machine, without the need to frequently change different types of grinding wheel equipment, thereby improving production efficiency and reducing production costs.

[0042] Working principle: When using this optical objective grinding tool, such as Figure 1-6As shown, the optical objective lens to be polished is first fixed on the optical objective lens support 2. Then, several fine grinding heads 8 are placed in several mounting sleeves 7. Different fine grinding heads 8 are switched by the rotating mechanism 5 to improve work efficiency and reduce the time cost of changing grinding tools. Subsequently, the linear motion module 3 drives the connector 43 to extend into the connecting groove 81, and the drive motor 42 drives the fine grinding head 8 to rotate to perform fine grinding on the optical objective lens. The bearing connection between the mounting sleeve 7 and the turntable 6 reduces the frictional impact on the turntable 6 caused by the rotation of the fine grinding head 8. At the same time, the elastic element 73 allows the fine grinding head 8 to continuously polish the optical objective lens as the drive mechanism 4 moves down, ensuring the fine grinding effect. When several fine grinding heads 8 are set with different grit numbers, the grinding tool can achieve multiple processing stages without frequently changing different types of grinding tools, thus improving production efficiency and reducing production costs.
