Description

Technical Field

[0001] This utility model relates to the field of micromachining technology, specifically to an auxiliary fixture for micromachining optical instrument parts. Background Technology

[0002] In the optical instrument manufacturing industry, with the continuous advancement of technology, the requirements for the micro-machining precision of optical instrument parts are increasing. Traditional part clamping devices have relatively simple structures, making it difficult to ensure that the parts are subjected to uniform force during processing, which can easily lead to skew. Furthermore, when traditional clamping devices are installed on the processing worktable, they lack precise horizontal adjustment functions. During the micro-machining process, due to the extremely high processing precision, even the slightest tilt of the device or displacement caused by vibration can cause deviations in the processing position of the parts, resulting in an increase in scrap rate and seriously affecting the production quality and efficiency of optical instruments.

[0003] To address this, we propose an auxiliary fixture for the micromachining of optical instrument parts. Utility Model Content

[0021] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that the description of these embodiments is for the purpose of helping to understand this utility model, but does not constitute a limitation on this utility model.

[0022] Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0023] Please see the appendix Figure 1 - Appendix Figure 5This utility model discloses an auxiliary fixture for micromachining optical instrument parts, comprising a housing 1 and a cover 2. Inside the housing 1 are a left gripper and a right gripper. The left gripper mainly consists of a rotating rod 3, a telescopic rod 31, and a left suction cup. The rotating rod 3 has good rotational performance, while the connected telescopic rod 31 can adaptively adjust according to the clamping force provided by the right gripper, avoiding damage caused by hard clamping. The right gripper includes a helical rod 4, a rotator 41, and a right suction cup. The helical rod 4 is tightly connected to a turntable A and a rotating handle A. By rotating the rotating handle A, the helical rod 4 can be driven to perform precise rotational movement, thereby adjusting the clamping position of the right gripper. The other side of the rotating rod 3 is connected to the motor 4001. Threaded holes are provided around the bottom of the housing 1. Threaded rod A 5, threaded rod B 5001, adjustable nut 51, and fixing bracket 52 are cleverly installed in these threaded holes. By adjusting the adjustable nut 51, the relative position of threaded rod A 5 and threaded rod B 5001 can be precisely changed, thereby achieving fine adjustment of the height and level of the housing 1 to meet the needs of different processing scenarios. The fixing bracket 52 provides a solid support base for the entire fixture at the bottom, ensuring that it will not shake or shift during the micro-machining process, providing extremely reliable protection for the micro-machining of optical instrument parts.

[0024] In Example 1, a hole is provided on the left side of the box body 1, and a threaded hole is provided on the right side of the box body 1. The rotating rod 3 passes through the hole, and a telescopic rod 31 is installed inside one side of the rotating rod 3. A left suction cup is installed on one side of the telescopic rod 31. The spiral rod 4 passes through the hole on the right side of the box body 1. A rotator 41 is installed on one side of the spiral rod 4. A right suction cup is installed on the front side of the rotator 41. A turntable A is installed on one side of the spiral rod 4. A rotating handle A is provided above the turntable. A level 53 is provided on the front side of the box body 1. The threaded hole is connected to the threaded rod A 5. The threaded rod A 5 is connected to the threaded rod B 5001 through an adjustable nut 51. A fixing bracket 52 is installed at the bottom of the threaded rod B 5001. Four positioning holes are evenly provided above the fixing bracket 52.

[0025] Specifically, a hole is provided on the left side of the housing 1, providing a channel for the installation of the rotating rod 3. A telescopic rod 31 is cleverly installed inside the rotating rod 3. Thanks to its flexible telescopic characteristics, the telescopic rod 31 can adjust its length in real time according to the size and shape of different optical instrument parts, thus ensuring that the left suction cup can fit well against the surface of the part and avoiding hard clamping that could damage the part. A threaded hole is also provided on the right side of the housing 1 for the spiral rod 4 to pass through. One side of the spiral rod 4 is tightly connected to the rotator 41, and the right suction cup is securely installed on the front side of the rotator 41. When it is necessary to adjust the clamping state of the right clamp, the operator only needs to gently rotate the spiral rod 4. The connected turntable A and the rotating handle A above the turntable A will rotate accordingly, thereby driving the screw rod 4 to rotate precisely. Under the rotation of the screw rod 4, the rotator 41 and the right suction cup will move along the predetermined trajectory, thereby achieving precise clamping and positioning of the parts. The front of the housing 1 is carefully equipped with a level 53. The threaded hole and the threaded rod A 5 are tightly connected by a precise thread fit. The threaded rod A 5 is connected to the threaded rod B 5001 by means of an adjustable nut 51. The bottom of the threaded rod B 5001 is firmly installed with a fixing frame 52. Four positioning holes are evenly distributed on the fixing frame 52. These positioning holes can further help to fix the position of the entire device.

[0026] In embodiment 2, a mounting bracket 21 is provided above the cover 2, and an observation port is provided in the middle of the cover 2. A hole is provided in the middle of the mounting bracket 21 and the observation port. A connecting rod 22 is provided in the hole. A turntable B is provided above the connecting rod 22. A rotating handle B is provided above the turntable. A grinder 23 is installed at the bottom of the connecting rod 22. A safety hole is provided on the right side of the housing 1 and on both sides of the turntable A. A safety pin 6 is installed inside the safety hole. A protective shell 4002 is provided on the outside of the motor 4001. The protective shell 4002 is fixed to one side of the housing 1 by screws. The rear side of the housing 1 is connected to the cover 2 through a rotating shaft. A drain pipe 7 is installed at the bottom of the rear side of the housing 1.

[0027] Specifically, a mounting bracket 21 is securely mounted on top of the cover 2, and an observation port is precisely opened in the center of the cover 2. This observation port is made of a highly transparent and wear-resistant light material, allowing operators to clearly see the processing status of the parts inside the housing 1. This facilitates real-time monitoring of the processing progress and timely adjustments by the operator. Holes are carefully reserved between the mounting bracket 21 and the observation port, and connecting rods 22 are tightly installed in the holes. The B turntable is cleverly connected above the connecting rod 22. The B turntable and the connecting rod 22 are reliably connected by a high-precision key connection. When the operator rotates the B rotary handle above the B turntable, the torque can be stably transmitted to the B turntable. The connecting rod 22 drives the bottom grinder 23 to move up and down. The right side of the housing 1 and the two sides of turntable A are symmetrically provided with safety holes, and safety pins 6 are installed inside them. The safety pins 6 can effectively prevent turntable A from rotating due to accidental external impact or misoperation, thereby ensuring the clamping stability and processing safety of the right clamp. When it is necessary to adjust or maintain the right clamp, simply pull out the safety pins 6 to easily perform the relevant operations. The motor 4001 is tightly wrapped with a protective shell 4002. The protective shell 4002 is firmly fixed to one side of the housing 1 with high-strength screws. The rear side of the housing 1 is flexibly connected to the cover 2 through a rotating shaft. A drain pipe 7 is installed at the bottom of the rear side of the housing 1.

[0028] Working principle:

[0029] First, the optical instrument part requiring micromachining is placed inside housing 1, between the left and right grippers. Then, based on the part's dimensions, the right gripper is used for initial positioning. By rotating handle A, the screw rod 4 is rotated, causing the rotator 41 and the right suction cup to move along the axis of the screw rod 4, gradually approaching the part until the right suction cup contacts the right side surface of the part and provides a certain clamping force. At this time, the telescopic rod 31 in the left gripper will adaptively adjust its length according to the clamping force applied by the right gripper, ensuring that the left suction cup fits tightly against the left side surface of the part, achieving stable clamping from both sides. During the clamping process, the level 53 on the front side of housing 1 can be observed, and the adjustable nut 51 can be used to adjust the screw rod A and screw rod B. The relative position of the groove bar 5001 is adjusted to finely adjust the level of the housing 1, ensuring that the parts are in a horizontal state and providing precise initial conditions for micromachining. Then, the cover 2 is closed, and the condition of the parts inside the housing 1 can be observed in real time through the observation port on the cover 2. When micromachining operations such as grinding are required, the B rotary handle is rotated to drive the B turntable to rotate, which in turn causes the connecting rod 22 to drive the bottom grinder 23 to move up and down, performing precise micromachining on the parts. At the same time, the safety pins 6 installed in the safety holes on the right side of the housing 1 and on both sides of the A turntable prevent the A turntable from rotating accidentally and affecting the clamping stability. The waste liquid generated during processing can be discharged through the drain pipe 7 at the bottom rear of the housing 1. At this point, the entire workflow is completed.
