Description

Technical Field

[0001] This utility model relates to the field of clamping technology, and more specifically, to a crystal clamping device for laser equipment. Background Technology

[0002] With the rapid development of my country's overall economy, the laser crystal material industry has also grown rapidly. As the most important laser crystal to date, laser crystal has become the most mature and mainstream laser crystal material in the world, occupying a very important position in the field of solid-state laser applications. More than 50% of solid-state lasers worldwide use laser crystals. As the output power requirements of lasers continue to increase, the required geometric dimensions of laser crystals are also getting larger and larger, and the processing difficulty and quality requirements are also getting higher and higher. Before being put into use, laser crystals need to be polished. Because the elastic limit and tensile limit of laser crystal materials are very close, when the load the material bears slightly exceeds the elastic limit, it will break and fail. The processed surface is prone to micro-cracks and pits, which seriously affect its surface quality and performance. During the processing of laser crystals, the crystals need to be clamped. Existing clamping devices have complex structures. During the clamping process, the laser crystal is very prone to loosening and shaking. Moreover, the clamping is complicated and inefficient, which leads to low processing efficiency of laser crystals.

[0003] To address the aforementioned problems, regarding existing clamping devices that are complex in structure, prone to loosening and wobbling of the laser crystal during clamping, and suffer from complex clamping and low clamping efficiency, extensive searching revealed a crystal clamping device for laser equipment with patent publication number CN221849970U. This device includes a main mounting assembly with several limiting components, a clamping component within each limiting component, a connecting hole in the center of the clamping component, a clamping power component at the bottom of the main mounting assembly, a clamping control component at the output end of the clamping power component, and positioning components on the four sides of the clamping component on the main mounting assembly. This novel clamping device features a clever structural design, strong practicality, and ease of operation. Using this device, stable crystal clamping is achieved, effectively improving clamping efficiency, preventing crystal loosening, and enhancing crystal clamping stability. However, the technical solution provided by this patent has the following problems:

[0004] (1) During the downward movement of the clamping control component driven by the clamping power cylinder in the existing device, the outer auxiliary inclined surface of the clamping control head contacts the guide inclined surface set on the clamping block, which causes the clamping block to spread outward, so that the clamping block and the shoulder seat clamp the crystal. However, at this time, the clamping end of the clamping block is in an inclined state, and only the top end contacts the crystal. The crystal is prone to tilting due to uneven force, which affects the clamping effect.

[0005] (2) The existing devices can only hold crystals of relatively limited shapes and sizes, and cannot meet the needs of holding crystals of different shapes and sizes.

[0006] This invention can prevent the crystal from tilting and increase the clamping range of the device. Utility Model Content

[0007] The present invention aims to solve the technical problems mentioned in the background art and provide a crystal clamping device for laser equipment.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a crystal clamping device for laser equipment, comprising: a main mounting plate, four clamping power cylinders disposed below the main mounting plate, a plurality of sliding grooves disposed on the main mounting plate, the four clamping power cylinders being evenly distributed in two rows and two columns, the output ends of the clamping power cylinders being connected to a turntable via an output shaft, the turntable having four arc-shaped grooves, sliders disposed within the arc-shaped grooves, a connecting block being connected to the bottom of the sliders, a clamping block being connected to the upper end of the sliders, and an elastic pad being connected to the side of the clamping block pointing towards the center of the turntable.

[0009] A further preferred option: The four arc-shaped grooves on the turntable are arranged in a circular array. The arc-shaped grooves are composed of large arc-shaped grooves and small arc-shaped grooves. The shape of the large arc-shaped grooves is obtained by the small arc-shaped grooves spreading outward at equal intervals. The large arc-shaped grooves are located below the small arc-shaped grooves.

[0010] A further preferred embodiment: The slider is slidably installed in the arc-shaped groove. The slider has a cylindrical structure, the diameter of which is equal to the width of the small arc-shaped groove, and the height of which is greater than the height of the turntable. The connecting block is circular, and the diameter and thickness of the connecting block are equal to the width and height of the large arc-shaped groove.

[0011] A further preferred embodiment: There are 16 slides, arranged in groups of 4 in a cross shape above the turntable. The 4 slides point towards the center of the turntable, and the top surface of the slides is flush with the top surface of the slider.

[0012] A further preferred embodiment: the clamping block is a cuboid block, the width of the clamping block is greater than the width of the slide groove, and the clamping block is parallel to the slide groove.

[0013] A further preferred option: the elastic pad is made of rubber.

[0014] A further preferred option: the turntable is mounted on the main mounting plate.

[0015] Beneficial effects:

[0016] 1. Through the staggered design of the large arc groove and the small arc groove, the connecting block is pressed against the bottom by the boss formed between the large arc groove and the small arc groove during the rotation of the turntable. This serves as a bottom limit for the slider, preventing the slider from flying off the clamping block during movement. The groove not only limits the movement path of the slider, making the slider only drive the clamping block to make a straight line movement towards the center of the turntable, but also serves as a top limit for the slider.

[0017] 2. The elastic pad is made of rubber, which has good deformability and resilience. When the crystal is a cylinder or cuboid of different sizes, the elastic pad deforms under the compression of the crystal, thus fitting into the crystal and fixing it. Combined with the cross-shaped distribution structure of the groove, it increases the range of crystals that can be clamped.

[0018] 4. In summary, this crystal clamping device for laser equipment, by incorporating structures such as arc-shaped grooves, sliding grooves, and elastic pads, serves to prevent the crystal from tilting and to increase the clamping range of the device. Attached Figure Description

[0023] The following will refer to the appendix in the embodiments of this utility model. Figures 1-3 The technical solutions in the embodiments of this utility model will be clearly and completely described.

[0024] Please see Figure 1-3 In this embodiment of the present invention, a crystal clamping device for a laser device includes: a main mounting plate 1, four clamping power cylinders 2 are arranged below the main mounting plate 1, a plurality of sliding grooves are provided on the main mounting plate 1, the four clamping power cylinders 2 are evenly distributed in two rows and two columns, the output end of the clamping power cylinders 2 is connected to a turntable 3 through an output shaft 8, the turntable 3 is provided with four arc-shaped grooves, a slider 4 is arranged in the arc-shaped grooves, a connecting block 5 is connected to the bottom of the slider 4, a clamping block 6 is connected to the upper end of the slider 4, and an elastic pad 7 is connected to the side of the clamping block 6 pointing towards the center of the turntable 3.

[0025] In this embodiment of the utility model, the four arc-shaped grooves on the turntable 3 are arranged in a circumferential array. The arc-shaped grooves are composed of large arc-shaped grooves and small arc-shaped grooves. The shape of the large arc-shaped grooves is obtained by the small arc-shaped grooves spreading outward at equal intervals. The large arc-shaped grooves are located below the small arc-shaped grooves. The slider 4 is slidably installed in the arc-shaped grooves. The slider 4 has a cylindrical structure. The diameter of the slider 4 is equal to the width of the small arc-shaped grooves. The height of the slider 4 is greater than the height of the turntable 3. The connecting block 5 is circular. The diameter and thickness of the connecting block 5 are equal to the width and height of the large arc-shaped grooves. Through the staggered design of the large arc-shaped grooves and the small arc-shaped grooves, the connecting block 5 is pressed against the bottom by the protrusion formed between the large arc-shaped grooves and the small arc-shaped grooves during the rotation of the turntable 3, which plays a bottom limiting role for the slider 4 and prevents the slider 4 from flying out of the clamping block during the movement.

[0026] In this embodiment of the utility model, there are 16 sliding grooves, arranged in a cross shape in groups of 4 above the turntable 3. The 4 sliding grooves point towards the center of the turntable 3, and the top plane of the sliding groove is flush with the top plane of the slider 4. The clamping block 6 is a cuboid block, and the width of the clamping block 6 is greater than the width of the sliding groove. The clamping block 6 is parallel to the sliding groove. The setting of the sliding groove limits the movement path of the slider 4, so that the slider 4 can only drive the clamping block 6 to make a straight line movement towards the center of the turntable 3, and the clamping block 6 plays the role of top limiting the slider 4.

[0027] In this embodiment of the invention, the elastic pad 7 is made of rubber, which has good deformability and resilience. When the crystal is a cylinder or cuboid of different sizes, the elastic pad 7 deforms under the compression of the crystal, thereby fitting into the crystal and fixing it.

[0028] Working principle: Place the crystal on the clamping block 6, start the clamping power cylinder 2 to drive the turntable 3 to rotate. The slider 4 rotates with the arc groove, and is restricted by the groove and slides along the groove to drive the clamping block 6 to slide towards the center of the turntable 3 until the elastic pad 7 is in contact with the crystal. Then the clamping power cylinder 2 is turned off.
