Description

Technical Field

[0001] The present invention relates to the technical field related to crystal laser inner engraving processing, and in particular to an adjustable special-shaped supporting fixture for crystal laser inner engraving processing. Background Art

[0002] Crystal engraving is a process in which a laser machine shoots a laser of a certain wavelength into the interior of glass or crystal, causing tiny cracks in specific parts of the interior to form bubbles, thereby outlining a preset shape. It also refers to the handicrafts produced by this process. Before engraving the crystal, a fixture is needed to limit the position of the crystal, for example:

[0003] The crystal inner carving fixture disclosed by the publication number "CN110369888B" has a movable seat that moves along two sets of slide rails, so that the distance between the movable seat and the fixed seat can be adjusted, so that the left vertical splint and the right vertical splint can meet the needs of clamping crystal bodies with different left and right widths; at this time, the end cover is stuck on the upper ends of the left vertical splint and the right vertical splint, and then the screw rod is rotated by the handwheel to push the movable block to move in the direction close to the right vertical splint until the movable block clamps the right vertical splint, which can further enhance the firmness of the left vertical splint and the right vertical splint in clamping the crystal body. When in use, the device is used to clamp crystal bodies with different left and right widths. However, when clamping special-shaped crystals, it cannot be handled very stably when only two sets of splints are used to limit the crystal. Offset will occur during the limiting process, resulting in processing failures during processing.

[0004] Therefore, we proposed an adjustable special-shaped support fixture for crystal laser engraving processing to solve the above problems. Summary of the Invention

[0005] The purpose of the present invention is to provide an adjustable special-shaped support fixture for crystal laser inner engraving processing, so as to solve the problem raised in the above background technology that the crystal fixtures currently on the market are used to clamp crystal bodies with different left and right widths. However, when clamping special-shaped crystals, only two sets of clamps are used to limit the crystal, which cannot be handled very stably. During the limiting process, offset will occur, resulting in processing failures during processing.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: an adjustable special-shaped support fixture for crystal laser engraving, comprising a support base, wherein a workbench is fixedly mounted on the top of the support base, and the workbench provides positioning for the special-shaped crystal;

[0007] A driving assembly is installed inside the workbench by means of bolts, and the output end of the driving assembly is connected to a positioning mechanism, and the center positioning of the positioning mechanism is used to avoid the phenomenon of deviation during operation.

[0008] As the preferred technical solution of the present application, the positioning mechanism includes an output end of a driving component that passes through the bottom position of the main bevel gear and is connected to the top end of the threaded rod, and the outer side of the threaded rod is threadedly connected to the inner side of the connecting sleeve. The bottom position of the connecting sleeve is fixed at the top center of the pressure plate, which can provide a power source for the adjustable clamping mechanism, and can perform multi-range limiting on the special-shaped clamp. The main bevel gear can be driven to rotate by starting the driving component, which will cause the five groups of main bevel gears meshed and connected on the outside of the main bevel gear to rotate, and can drive the five groups of moving components to move relative to each other, thereby achieving the purpose of centering positioning.

[0009] As a preferred technical solution of the present application, the positioning mechanism includes a main bevel gear connected to the output end of the driving assembly, and five groups of sub-bevel gears are meshed and connected at the bottom outer position of the main bevel gear. The center position of the sub-bevel gear is keyed to one end of the screw, and the outer side of the screw is threadedly connected to the inner side of the moving assembly, so that the screw can drive the five groups of moving assemblies to move relative to each other.

[0010] As the preferred technical solution of the present application, the interior of the movable component includes a hexagonal nut threadedly connected to the screw rod, and the hexagonal nut is fixed to the inner position of the movable block. In addition, the bottom shape of the movable block is trapezoidal, and two sets of support rods are fixed at the top position of the movable block. The top of the support rod is fixed to the rear position of the fitting block by screws. At the same time, the movable component is slidably set at the top position of the workbench, so that when the movable component moves, it can drive the support rod to slide in the sliding groove opened on the top of the workbench, which can facilitate the adjustment of the position of the movable component.

[0011] As a preferred technical solution of the present application, the interior of the workbench includes a sliding groove for facilitating the sliding of the movable component, and a mounting frame is fixed under the workbench. In addition, the mounting frame is installed at the top position of the support base by bolts, and the rotating groove is opened at the top position of the sliding groove. The inner wall of the sliding groove is connected to the axial end position of one end of the secondary bevel gear by a bearing, so that the secondary bevel gear can rotate inside the sliding groove and be fixed to the top position of the support base by the mounting frame.

[0012] As the preferred technical solution of the present application, the adjustable clamping mechanism includes an elastic bag with a certain interval below the pressure plate, the bottom position of the elastic bag is fixed to the internal position of the support base, and the outer side of the elastic bag is connected to the diversion hose through the oil delivery hose, and the top position of the diversion hose is connected to the lower end position of the diversion hose. At the same time, one end of the diversion hose extends into the internal position of the bonding block, and the five groups of bonding blocks are connected by matching soft strips. In addition, a top rod extends from the inside of the bonding block, which can limit the special-shaped crystal. By setting the matching soft strips, the five groups of bonding blocks are supported to prevent them from being folded during the oil delivery process.

[0013] As a preferred technical solution of the present application, sliders are fixed on both sides of the pressure plate, and the bottom position of the slider is slidably set in the slide groove opened on the inner wall of the support base, so that the pressure plate can slide inside the slide groove through the slider.

[0014] As a preferred technical solution of the present application, a group of piston blocks are fixed to one end of the push rod, and a group of return springs are fixed to one side of the piston block. In addition, one end of the return spring is fixed to the inner wall position of the oil chamber, so that the push rod can limit the special-shaped crystal.

[0015] As the preferred technical solution of the present application, one end of the oil chamber is fixed inside the fitting block, and one side of the oil chamber is connected to one end of the diversion hose, so as to facilitate the delivery of hydraulic oil to the inside of the oil chamber. When the piston block is pushed to a position, the push rod can limit the special-shaped crystal, thereby carrying out oil delivery through the oil chamber.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: the adjustable special-shaped support fixture for crystal laser inner engraving processing can start the drive component, so that the output end of the drive component can drive the positioning mechanism and the adjustable clamping mechanism to work, so that the support fixture can stably fix the special-shaped crystal and prevent the special-shaped crystal from shifting during operation. The specific contents are as follows:

[0017] 1. Driven by the driving assembly, the key-connected main bevel gear drives the meshing-connected auxiliary bevel gear to rotate, which can make the auxiliary bevel gear move relative to the five groups of moving components through the setting of the screw, and can center the special-shaped crystal, which is convenient for the later limit processing;

[0018] Furthermore, the setting of the workbench facilitates the stable sliding of the secondary bevel gear and the screw inside the workbench, so that the five sets of screws can drive the moving components to slide stably inside the workbench when rotating;

[0019] Furthermore, the bottom position of the moving component is set in a trapezoidal shape, which allows the moving component to slide in the sliding groove. In addition, the support rod provided by the moving component will drive the fitting block to limit the special-shaped crystal. In addition, the matching soft strip can prevent the oil hose from being bent when the fitting block moves, so as to facilitate the transportation of hydraulic oil.

[0020] 2. The pressure plate and the elastic bag, through the movement of the pressure plate, squeeze the top of the elastic bag, so that the oil inside the elastic bag will be transported to the inside of the oil hose, and the hydraulic oil can be transported to the inside of the diversion hose through the oil hose, so that the push rod can slide inside the fitting block, so that several push rods can limit the special-shaped crystal;

[0021] Furthermore, hydraulic oil is transported to the inside of the diversion hose, and hydraulic oil can be injected into the oil chamber, so that the piston block will drive the push rod to move, and the push rod can be reset later by the reset spring, which can limit the position of different special-shaped crystals to prevent the crystals from shifting.

The positioning mechanism includes a main bevel gear 4 connected to the output end of the driving component 3, and five groups of sub-bevel gears 5 are meshed and connected at the outer bottom position of the main bevel gear 4. The center position of the sub-bevel gear 5 is keyed to one end of the screw 6, and the outer side of the screw 6 is threadedly connected to the inner position of the moving component 7; when the special-shaped crystal is limited, by starting the output end of the driving component 3 to rotate, the keyed main bevel gear 4 will rotate while also driving the meshed sub-bevel gear 5 to rotate. At this time, the shaft end position of the sub-bevel gear 5 rotates inside the rotating groove 203. At this time, the screw 6 keyed at the other side of the sub-bevel gear 5 also drives the threaded moving component 7 to move, which will cause the five groups of moving components 7 to move relative to each other. Through relative movement, the special-shaped crystal above the workbench 2 can be centered and positioned, thereby solving the problem that the special-shaped crystal will be offset when limiting.

The inner wall and one end of the shaft end of the secondary bevel gear 5 are connected by a bearing; when the moving component 7 moves, the hexagonal nut 701 set on the outside of the screw 6 is slid through the movement of the moving component 7, so that the moving component 7 can drive the moving block 702 and the support rod 703 to move. In addition, the support rod 703 will also drive the fitting block 15 to move, thereby facilitating the limiting treatment of the special-shaped crystal. In addition, when the moving component 7 moves, since each group of moving components 7 and the moving component 7 are connected by the matching soft strip 16, when the moving component 7 and the moving component 7 move toward the position of the workbench 2, the matching soft strip 16 will become a bow shape, and fit the oil hose 13 and the diversion hose 14 on one side, so that the inside of the fitting block 15 can be stably oiled.
