Description

Technical Field

[0001] The utility model belongs to the technical field of optical fiber end face polishing, and particularly relates to a polishing device for optical fiber end face polishing. Background Art

[0002] Optical fiber is an optical fiber made of high-purity glass or plastic. It transmits light signals through the principle of total reflection. It is widely used in communications, medical treatment, sensing and other fields to achieve long-distance and high-speed information transmission. The optical fiber end face polishing device is a precision mechanical tool specially used for processing the end face of optical fiber connector. It removes burrs and defects left after optical fiber cutting through a series of fine grinding processes, and ensures that the end face reaches extremely high flatness and smoothness to reduce signal loss and improve the quality and stability of optical fiber connection.

[0003] The existing polishing device for polishing the end face of an optical fiber polishes the end face of the optical fiber by means of an eccentric polishing plate, but the polishing plate cannot rotate to achieve polishing of the end face of the optical fiber. Since the polishing plate only performs eccentric movement, it cannot achieve all-round contact with the end face of the optical fiber, which may cause uneven wear on various parts of the end face, thereby affecting the flatness and consistency of the end face. It may also lead to limited changes in the contact area and angle during the polishing process, which increases the processing time and steps, and is not conducive to completing the polishing operation quickly and efficiently. Utility Model Content

[0004] In view of this, the utility model aims to improve the polishing accuracy and quality of the optical fiber end face by providing a polishing device for polishing the optical fiber end face in order to address the deficiencies in the prior art. The polishing device can effectively improve the polishing accuracy and quality by allowing the polishing plate to rotate while being eccentric. The self-rotation design enables each position of the optical fiber end face to have the opportunity to fully contact with the polishing plate, thereby greatly improving the efficiency of the entire polishing process.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: a polishing device for polishing the end face of an optical fiber, comprising a shell, a mounting plate is arranged on the rear side of the shell, an electric push rod is arranged on the upper end of the mounting plate, a mounting ring is arranged on the telescopic end of the electric push rod, bolts are rotatably arranged on the left and right sides of the outer arc surface of the mounting ring, a water pipe is arranged in the mounting hole opened inside the mounting ring, an eccentric self-rotation polishing mechanism is arranged inside the shell, the eccentric self-rotation polishing mechanism comprises a rotating column rotatably arranged inside the shell, a rotating frame is arranged on the upper fixed sleeve of the outer arc surface of the rotating column, a placement plate is rotatably connected to the left side of the rotating frame through a rotating shaft, a polishing plate is placed on the upper end of the placement plate, a gear is arranged at the lower end of the rotating shaft, an internal gear ring meshing with the gear is arranged at the upper end of the shell, an electric drive unit for driving the rotating column to rotate is arranged inside the shell, and mounting mechanisms for installing the polishing plate are arranged on the left and right sides of the placement plate, the electric drive unit comprises a motor arranged inside the shell, and the output shaft of the motor is connected to the lower end of the rotating column through a coupling.

[0006] As a further improvement of the utility model, the mounting mechanism includes frame plates respectively arranged on the left and right sides of the placing plate, sliding columns are slidably arranged inside the two frame plates, pressure plates are respectively arranged at the lower ends of the two sliding columns, the two pressure plates are in contact with the upper surface of a grinding plate, springs are respectively arranged between the frame plates and the placing plate, the two springs are respectively sleeved on the corresponding outer arc surfaces of the sliding columns, auxiliary pulling components are respectively arranged at the upper ends of the two sliding columns, the auxiliary pulling components include pull plates respectively arranged at the upper ends of the two sliding columns, and evenly distributed anti-slip protrusions are arranged on the outer arc surfaces of the two pull plates.

[0007] As a further improvement of the utility model, a control panel is arranged on the front side of the shell, and the motor and the electric push rod are electrically connected to the control panel.

[0008] As a further improvement of the utility model, support feet are respectively provided at the four corners of the lower end of the shell.

[0009] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0010] The optical fiber mounting plate that needs to be polished is placed inside the mounting ring, and the optical fiber mounting plate is fixed by rotating bolts. Then, the electric push rod is controlled to operate, and the telescopic end drives the optical fiber on the optical fiber mounting plate to move downward, so that the end face of the optical fiber contacts the polishing plate. Then, the motor is controlled to operate, and the output shaft rotates to drive the rotating frame on the rotating column to rotate, so that the polishing plate on the placement plate rotates eccentrically to polish the end face of the optical fiber. At the same time, the gear on the rotating shaft at the lower end of the placement plate is affected by the meshing relationship of the internal gear ring, causing the rotating shaft to rotate, and the polishing plate on the placement plate rotates to polish the end face of the optical fiber. The eccentricity and the self-rotation of the polishing plate can effectively improve the polishing accuracy and quality. The self-rotation design allows each position of the optical fiber end face to have the opportunity to fully contact the polishing plate, greatly improving the efficiency of the entire polishing process.

[0011] Secondly, by pulling the pull plates on both sides, the anti-slip protrusions on the pull plates can prevent people from slipping, so that the pressure plates on both sides move upward, the old grinding plate can be taken out, the spring is in a compressed state at this time, and the new grinding plate is placed on the placement plate, and then the pull plates on both sides are released. At this time, the springs rebound quickly and drive the pressure plates on both sides to move downward to fix the grinding plates, so that the grinding plates can be quickly replaced.

[0012] Thirdly, by connecting the water pipe to an external water pump so that the water pipe sprays water to the upper end of the polishing plate, it can help reduce the temperature of the polishing area and avoid deformation or performance damage of the optical fiber material due to high temperature.

[0013] Fourthly, the supporting feet at the lower end of the shell can provide stable support for the shell, making the operation of the grinding device more stable. BRIEF DESCRIPTION OF THE DRAWINGS
