Description

Technical Field

[0001] This utility model belongs to the field of laser engraving technology, specifically a clamping device for a laser engraving machine. Background Technology

[0002] Laser engraving technology, due to its high precision, high efficiency, and non-contact processing characteristics, has been widely used in the processing of various materials such as wood, metal, and plastic. During laser engraving, the workpiece is typically placed on the worktable of the laser engraving machine and clamped in place by a fixture. Then, the laser head engraves patterns or text onto the workpiece.

[0003] In the laser engraving process, the clamping stability of the workpiece has a significant impact on the engraving quality and precision. When clamping some thin plates, the clamping force on both sides often causes problems such as unstable clamping and easy deformation of the workpiece. Utility Model Content

[0004] The present invention aims to overcome the shortcomings of the existing technology by providing a clamping device for a laser engraving machine. This invention uses a front pressure roller and a rear pressure roller to press onto the sheet metal, positioning the area between the front and rear pressure rollers to facilitate laser engraving of the sheet metal and reduce sheet metal deformation.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a clamping device for a laser engraving machine, comprising a worktable and a laser processing head above it, wherein the worktable is provided with a positioning stop, and a positioning strip is provided on one side of the positioning stop, the positioning stop and the positioning strip being perpendicular to each other in the horizontal plane; the laser processing head is mounted on a crossbeam, the crossbeam being connected to the worktable via a sliding part; a clamping mechanism is also provided on the crossbeam, the clamping mechanism comprising a front pressure roller, a rear pressure roller and a bracket, the bracket being connected below the crossbeam, the front pressure roller and the rear pressure roller being arranged correspondingly at the lower end of the bracket, the front pressure roller and the rear pressure roller abutting against the positioning stop; the laser processing head is located between the front pressure roller and the rear pressure roller.

[0006] Preferably, both the front and rear pressure rollers are fitted with rubber sleeves.

[0007] Preferably, the bracket includes a front support rod and a rear support rod. One end of the front support rod is fixedly connected to the bracket, and the other end is connected to the front pressure roller. One end of the rear support rod is rotatably connected to the bracket, and the other end is connected to the rear pressure roller. An elastic adjustment mechanism is provided on the front side of the rear support rod.

[0008] Preferably, the elastic adjustment mechanism includes a sliding sleeve and a sliding rod that are slidably connected. One end of the sliding sleeve is rotatably connected to the bracket, and one end of the sliding rod is rotatably connected to the rear support rod. A spring is provided inside the sliding sleeve, and a stop block is provided on the sliding rod. One end of the spring abuts against the stop block, and the other end abuts against the bottom of the sliding sleeve.

[0009] Preferably, a baffle is provided on the rear side of the rear support rod.

[0010] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0011] (1) Place the plate on the workbench, with one side against the positioning stop and the other side against the positioning stop. The sliding part drives the cross frame to move, and the front pressure roller, the rear pressure roller and the laser processing head move synchronously. The front pressure roller first disengages from the positioning stop and presses on the plate to play a positioning role. After moving forward for a while, it stops. The laser processing head starts to process and engrave the plate. After completion, it continues to move. The rear pressure roller presses on the plate to position the area between the front pressure roller and the rear pressure roller. At the same time, it presses the plate from top to bottom to reduce the deformation of the plate.

[0012] (2) By using the elastic adjustment mechanism to give the rear support rod a backward thrust, the rear pressure roller will have a friction. While pressing the plate, it can also straighten the thinner plate, which is more conducive to processing. Attached Figure Description

The worktable 1 is provided with a positioning stop 11, and a positioning stop 12 is provided on one side of the positioning stop 11. The positioning stop 11 and the positioning stop 12 are perpendicular to each other in the horizontal plane. The laser processing head 2 is mounted on a crossbeam 21, which is connected to the worktable 1 via a sliding part 3. The crossbeam 21 is also provided with a pressing mechanism 4, which includes a front pressure roller 41, a rear pressure roller 42, and a bracket 43. The bracket 43 is connected to the lower part of the crossbeam 21. The front pressure roller 41 and the rear pressure roller 42 are arranged correspondingly at the lower end of the bracket 43, and the front pressure roller 41 and the rear pressure roller 42 abut against the positioning stop 11. The laser processing head 2 is located between the front pressure roller 41 and the rear pressure roller 42.

[0026] The sheet material is placed on the worktable 1, with one side abutting against the positioning stop 11 and the other side abutting against the positioning stop 12. The sliding part 3 drives the cross frame 21 to move. The front pressure roller 41, the rear pressure roller 42 and the laser processing head 2 move synchronously. The front pressure roller 41 first disengages from the positioning stop 11 and presses on the sheet material to play a positioning role. After moving forward for a while, it stops. The laser processing head 2 begins to process and engrave the sheet material. After completion, it continues to move. The rear pressure roller 42 presses on the sheet material, positioning the area between the front pressure roller 41 and the rear pressure roller 42, and pressing the sheet material from top to bottom to reduce the deformation of the sheet material.

[0027] Both the front pressure roller 41 and the rear pressure roller 42 are fitted with rubber sleeves.

[0028] like Figure 2 As shown, the bracket 43 includes a front support rod 44 and a rear support rod 45. One end of the front support rod 44 is fixedly connected to the bracket 43, and the other end is connected to the front pressure roller 41. One end of the rear support rod 45 is rotatably connected to the bracket 44, and the other end is connected to the rear pressure roller 42. An elastic adjustment mechanism 5 is provided on the front side of the rear support rod 45.

[0029] like Figure 2 and 3As shown, the elastic adjustment mechanism 5 includes a sliding sleeve 51 and a sliding rod 52 that are slidably connected. One end of the sliding sleeve 51 is rotatably connected to the bracket 43, and one end of the sliding rod 52 is rotatably connected to the rear support rod 45. A spring 53 is provided inside the sliding sleeve 51, and a stop block 54 is provided on the sliding rod 52. One end of the spring 53 abuts against the stop block 54, and the other end abuts against the bottom of the sliding sleeve 51. A baffle 55 is provided on the rear side of the rear support rod 45.

[0030] The elastic adjustment mechanism 5 provides a backward thrust to the rear support rod 45, which causes the rear pressure roller 42 to have a backward friction. While pressing the plate, it can also straighten the thinner plate, which is more conducive to processing.
