Description

Technical Field

[0001] The utility model relates to the technical field of laser crystal processing, in particular to a flipping and polishing device for laser crystal processing. Background Technique

[0002] A laser crystal is a crystal material that can convert the energy provided by the outside world into laser with high parallelism and monochromaticity that is coherent in space and time through an optical resonator. It is the working substance of a crystal laser. Crystal lasers are mostly columnar. During the production of laser crystals, it is often necessary to polish their surfaces, and for this purpose, a polishing device is required.

[0003] After retrieval, CN 217225009 U, a flipping and polishing device for laser crystal processing, places the laser crystal to be polished inside a fixed frame and makes it flush with the groove on the fixed plate. At the same time, the control panel is used to control the electric push rod to work, prompting the electric push rod to push the fixed plates on both the front and back sides to approach each other until the inner walls of the fixed plates are in contact with the laser crystal, and at the same time, the clamping plates are in contact with the upper and lower end faces of the laser crystal, so as to realize the clamping and fixing of laser crystals of different sizes.

[0004] However, there are still certain defects in the above application: when the above application controls the two fixed plates to clamp and fix the laser crystal, the clamping plate only uses a spring to fix the laser crystal. During the grinding process, the spring is deformed by force, which will cause the movement of the laser crystal and affect the polishing quality of the laser crystal. Therefore, corresponding technical solutions need to be designed to solve the existing technical problems. Content of the Utility Model

A plurality of clamping blocks are arranged in an array on the adjacent surfaces of the two disks, and a driving component for driving the plurality of clamping blocks to move synchronously in a direction close to or away from the axis of the disk is also arranged inside the disk.

[0008] As a further solution of the utility model: The driving assembly includes a turntable, a push-pull rod, a movable part and a connecting block. The turntable is rotatably arranged in the disc and is driven by a first motor arranged outside the disc. Inside the disc and around the turntable, a number of movable parts equal to the number of clamping blocks are also arranged in an array. The movable parts are slidably arranged through slide rails and are connected to the turntable through push-pull rods. Among them, one end of the push-pull rod is hinged to the movable part, and the other end is hinged to the turntable. The clamping block is connected to the movable part through a connecting block. A strip-shaped hole for the sliding of the connecting block is also opened on the side of the disc.

A fixed sleeve is installed on the side of one of the discs. The first motor is installed inside the fixed sleeve, and an external gear ring is fixedly installed on the fixed sleeve. The second motor is fixedly installed on the mounting seat, and a driving gear meshing with the external gear ring is installed at the output end of the second motor.

[0010] As a further solution of the utility model: An adjusting assembly is also arranged on the bottom plate. The adjusting assembly is used to adjust the distance between the two mounting seats and includes a bidirectional lead screw and a guide rod. Strip-shaped grooves are symmetrically opened on both sides of the servo driving module on the bottom plate. The bidirectional lead screw and the guide rod are respectively installed in the two strip-shaped grooves. Among them, the bidirectional lead screw is driven by a third motor arranged on the side of the bottom plate, and threaded bushings are symmetrically installed on the two threaded parts of the bidirectional lead screw.

A driving component for driving the plurality of clamping blocks 6 to move synchronously in a direction close to or away from the axis of the disc 5 is further arranged in the disc 5. By arranging the mounting seats 4, discs 5, turning module, clamping blocks 6 and driving component, during the process that the driving component drives the plurality of clamping blocks 6 on the two discs 5 to move synchronously in a direction close to the axis of the disc 5, stable clamping and fixing of both ends of the laser crystal can be realized. Moreover, after the servo drive module 2 drives the polishing module 3 to polish one side of the laser crystal, the turning module can also drive the disc 5 to rotate together with the laser crystal. By cycling in this way, comprehensive polishing of the laser crystal can be realized without repeatedly clamping the laser crystal, improving the polishing efficiency of the laser crystal.
