Description

Technical Field

[0001] The utility model relates to the technical field of clamping devices, in particular to a laser machine flat plate clamping device. Background Art

[0002] Laser machine is a general term for laser engraving machine, laser cutting machine and laser marking machine. Laser machine uses its high temperature working principle to act on the surface of the processed material, and at the same time, according to the graphics input into the machine, it draws the patterns and texts required by the customer. When the laser machine is working, the raw material needs to be clamped to prevent shaking.

[0003] Currently, when a laser machine processes a flat plate, the edge of the flat plate needs to be fixed. A single clamp is often used to fix the flat plate. Multiple clamps are needed to fix a flat plate. Each installation of a clamp takes a certain amount of time, which cannot improve the efficiency of the clamp use. Utility Model Content

[0004] 1. Technical issues to be resolved

[0005] In view of the deficiencies in the prior art, the utility model provides a laser machine plate clamping device having the advantages of being able to operate two symmetrical clamps at one time, thereby improving the efficiency of fixing the plate and solving the above-mentioned technical problems.

[0006] (II) Technical solution

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a laser machine plate clamping device, comprising a slide rail, the slide rail is installed on the top of the laser machine, the outer surface of the slide rail is slidably connected to a slider, the top of the slider is connected to a support plate, a clamping mechanism is installed on the top surface of the support plate, a connecting rod is inserted into the clamping mechanism, and both ends of the slide rail are fixedly connected to side plates;

[0008] The clamping mechanism includes a hinge seat, an L-shaped plate, a clamping block, a roller, a wedge block, a moving block and a hollow screw. The bottom of the hinge seat is fixedly connected to the L-shaped plate, and the hinge seat is rotatably connected to the clamping block through an axis. One end of the clamping block is rotatably connected to the roller. The upper surface of the L-shaped plate is slidably connected to the wedge block, the bottom of the wedge block is fixedly connected to the moving block, and the moving block is threadedly connected to the hollow screw.

[0009] Preferably, two sets of slide rails are installed on the top of the laser machine, and the outer surfaces of the two sets of slide rails are slidably connected to two sliding blocks, and the sliding blocks are connected to the support plate through bolts.

[0010] Through the above technical solution, the pallet is used to support the raw material cut by the laser machine, that is, the flat plate. A slider is installed on the lower surface of the pallet near both ends and is slidably connected to the slide rail. The pallet can be moved by pushing it, so that the distance between the two pallets can be adjusted, so that the two pallets can hold flat plates of different widths.

[0011] Preferably, a straight groove is provided through the top surface of the L-shaped plate, the bottom of the wedge block is slidably connected in the straight groove of the L-shaped plate, the L-shaped plate is connected to the top surface of the support plate by bolts, and the inclined surface of the wedge block contacts the roller.

[0012] Through the above technical solution, when the flat plate is placed on the upper surfaces of the two support plates, the two sides of the flat plate contact the hinge seat. At this time, if the hollow screw is rotated to drive the moving block to move, the moving block can drive the wedge block to move. Since the wedge block is in contact with the roller, the wedge block can gradually lift the roller, and under the action of the hinge seat, the head of the clamping block is forced to move downward, so that the clamping block can clamp the flat plate, thereby achieving the fixation of the flat plate.

[0013] Preferably, a plurality of clamping mechanisms are installed at equal intervals on the top surface of the support plate.

[0014] Through the above technical solution, by installing several clamping mechanisms, operators can select clamping mechanisms at appropriate positions to fix flat plates of different sizes. The number of clamping mechanisms used for flat plates of large sizes will be greater than that for flat plates of small sizes.

[0015] Preferably, limiting rings are provided at both ends of the hollow screw, and a keyway is opened in the hollow screw, both ends of the connecting rod are fixedly connected to the crank, and the outer surface of the connecting rod is fixedly connected to a key strip, and the outer surface of the connecting rod is slidably connected to the two hollow screws.

[0016] Through the above technical scheme, the key strip on the outer surface of the connecting rod matches the key groove in the hollow screw. When the support plate moves, it will drive the L-shaped plate, and then drive the entire clamping mechanism to move, and the hollow screw can move on the outer surface of the connecting rod. When the crank is turned to drive the connecting rod to rotate, the connecting rod can drive the two hollow screws to rotate. In this way, the two clamping mechanisms can be driven at the same time by turning the crank, thereby improving the efficiency of the clamping mechanism in fixing the flat plate.

[0017] Preferably, a rectangular hole is formed through the top surface of the pressing block, and a counterweight block is embedded in the rectangular hole.

[0018] According to the technical solution, by setting a counterweight block, the weight of the end of the pressing block close to the roller can be greater than the head of the pressing block, thereby preventing the head of the pressing block from drooping under normal conditions.

[0019] Compared with the prior art, the utility model provides a laser machine plate clamping device, which has the following beneficial effects:

[0020] 1. The utility model provides a connecting rod to slidably connect two hollow screws. When the support plate moves, it will drive the L-shaped plate, and then drive the entire clamping mechanism to move, and the hollow screw can move on the outer surface of the connecting rod. When the crank is turned to drive the connecting rod to rotate, the connecting rod can drive the two hollow screws to rotate, and the hollow screw drives the moving block to displace, and the moving block can drive the wedge block to move. Since the wedge block is in contact with the roller, the wedge block can gradually lift the roller, and under the action of the hinge seat, the head of the clamping block is forced to move downward, so that the clamping block can clamp the flat plate, thereby achieving the fixation of the flat plate, and the two clamping mechanisms can be driven at the same time by turning the crank, thereby improving the efficiency of the clamping mechanism in fixing the flat plate.

[0021] 2. The utility model sets a pallet to support the raw material for cutting by the laser machine, that is, the flat plate. A slider is installed on the lower surface of the pallet near both ends and is slidably connected to the slide rail.

[0028] See also Figure 1-Figure 4 A laser machine flat plate clamping device includes a slide rail 1, which is installed on the top of a laser machine table 8. The outer surface of the slide rail 1 is slidably connected to a slider 2, the top of the slider 2 is connected to a support plate 3, a clamping mechanism 4 is installed on the top surface of the support plate 3, a connecting rod 5 is inserted into the clamping mechanism 4, and both ends of the slide rail 1 are fixedly connected to side plates 9;

[0029] The clamping mechanism 4 includes a hinge seat 41, an L-shaped plate 42, a clamping block 43, a roller 44, a wedge block 45, a moving block 46 and a hollow screw 47. The bottom of the hinge seat 41 is fixedly connected to the L-shaped plate 42, and the hinge seat 41 is rotatably connected to the clamping block 43 through an axis. One end of the clamping block 43 is rotatably connected to the roller 44. The upper surface of the L-shaped plate 42 is slidably connected to the wedge block 45, the bottom of the wedge block 45 is fixedly connected to the moving block 46, and the moving block 46 is internally threadedly connected to the hollow screw 47.

[0030] Specifically, two sets of slide rails 1 are installed on the top of the laser machine 8, and the outer surfaces of the two sets of slide rails 1 are slidably connected to two sliders 2, and the sliders 2 are connected to the support plate 3 by bolts. The advantage is that the support plate 3 is used to support the raw material cut by the laser machine, that is, the flat plate, and a slider 2 is installed on the lower surface of the support plate 3 near both ends to be slidably connected to the slide rail 1, so that the support plate 3 can be moved by pushing it, so that the distance between the two support plates 3 can be adjusted, so that the two support plates 3 can hold flat plates of different widths.

[0031] Specifically, a straight groove is formed through the top surface of the L-shaped plate 42, and the bottom of the wedge block 45 is slidably connected to the straight groove of the L-shaped plate 42. The L-shaped plate 42 is connected to the top surface of the support plate 3 by bolts, and the inclined surface of the wedge block 45 is in contact with the roller 44. The advantage is that when the flat plate is placed on the upper surface of the two support plates 3, the two sides of the flat plate abut against the hinge seat 41. At this time, if the hollow screw 47 is rotated to drive the moving block 46 to move, the moving block 46 can drive the wedge block 45 to move. Since the wedge block 45 is in contact with the roller 44, the wedge block 45 can gradually lift the roller 44, and under the action of the hinge seat 41, the head of the pressing block 43 is forced to move downward, so that the pressing block 43 can press the flat plate, thereby achieving the fixation of the flat plate.

[0032] Specifically, a plurality of clamping mechanisms 4 are installed at equal intervals on the top surface of the support plate 3. The advantage is that by installing a plurality of clamping mechanisms 4, the operator can select a clamping mechanism 4 at a suitable position to fix the plates of different sizes, and the number of clamping mechanisms 4 used for a large plate is greater than that for a small plate.

When the crank 6 is turned to drive the connecting rod 5 to rotate, the connecting rod 5 can drive the two hollow screws 47 to rotate, so that the two clamping mechanisms 4 can be driven at the same time by turning the crank 6, thereby improving the efficiency of the clamping mechanism 4 in fixing the flat plate.

[0034] Specifically, a rectangular hole is formed through the top surface of the pressing block 43, and a counterweight block 7 is embedded in the rectangular hole. The advantage is that by providing the counterweight block 7, the weight of the end of the pressing block 43 close to the roller 44 can be greater than the head of the pressing block 43, so that the head of the pressing block 43 can be prevented from being drooped under normal conditions.

[0035] When in use, first push the support plate 3 to drive the slider 2 to move on the slide rail 1, so that the distance between the two support plates 3 can be adjusted according to the width of the flat plate, and then the flat plate is placed on the top surface of the two support plates 3, and then the connecting rod 5 is driven to rotate by turning the crank 6, and the connecting rod 5 can drive the two hollow screws 47 to rotate, and the hollow screw 47 drives the moving block 46 to move, and the moving block 46 can drive the wedge block 45 to move. Since the wedge block 45 is in contact with the roller 44, the wedge block 45 can gradually lift the roller 44, and under the action of the hinge seat 41, the head of the clamping block 43 is forced to move downward, so that the clamping block 43 can clamp the flat plate, thereby fixing the flat plate, and then the laser machine can process the flat plate. After the processing is completed, the crank 6 is reversed to make the clamping block 43 release the flat plate, so that the flat plate is convenient to remove from the support plate 3.
