Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] Example 1

[0019] See also Figures 1 to 4 , which is the first embodiment of the utility model, and this embodiment provides a technical solution: an adjustable laser engraving machine, comprising a body 1, a base 2 and a cross slide 6 arranged on the top surface of the body 1, a mobile platform 7 is installed on the top of the cross slide 6, a laser emitter 3 is installed on the top of the base 2, and a CCD light source 4 is installed at the front end of the laser emitter 3, a CCD camera 5 is installed on the top of the CCD light source 4, a partition bar 71 is fixed at the top center of the mobile platform 7, and the top area of ​​the mobile platform 7 can be isolated into two separate workstations for placing two processing material pieces, a T-shaped slide groove 72 is opened in the partition bar 71, and a clamping mechanism is arranged on the partition bar 71;

[0020] The clamping mechanism includes a T-shaped slide 81, a slide plate 82, a pressure strip 83 and a rubber block 84. The T-shaped slide 81 is slidably arranged in the T-shaped slide groove 72, and the slide plate 82 is slidably located on the top of the partition bar 71, and a movable structure is provided between the slide plate 82 and the T-shaped slide 81. The top surface of the slide plate 82 is fixed with a pressure strip 83, and the bottom surface of the pressure strip 83 is installed with a rubber block 84. The pressure strip 83 can be slid and adjusted to a suitable position later, and the rubber block 84 can be pressed on the top edge of the processed material piece, so as to realize the clamping and limiting of the processed material piece. The movable structure includes an inner groove 85 opened in the T-shaped slide 81, and a spring 86 and an inner slide block 87 are arranged in the inner groove 85. A connecting rod 88 is welded and fixed to the top surface of the inner slide block 87, and the top end of the connecting rod 88 passes through the top of the T-shaped slide 81 and is fixedly connected to the slide plate 82. Under the pushing action of the spring 86, the connecting rod 88 will Pull the slide plate 82 straight to ensure that the rubber block 84 at the bottom of the pressure strip 83 will press and limit the processing material piece placed on the top of the moving platform 7 to ensure the stability of the subsequent laser engraving processing. At the same time, the subsequent operator can lift the pressure strip 83, so that the slide plate 82 lifts the connecting rod 88 and the inner sliding block 87 compresses the spring 86, so that the rubber block 84 no longer contacts the processing material piece on the top of the moving platform 7, and the pressure strip 83 can be slid back and forth to make the T-shaped slide seat 81 slide in the T-shaped slide groove 72, and adjust the positions of the pressure strip 83 and the rubber block 84 until the pressure strip 83 and the rubber block 84 can slide to the edge of the processing material piece, then release the pressure strip 83, so that the spring 86 pushes the inner sliding block 87 back, and the connecting rod 88 pulls the pressure strip 83 and the rubber block 84 back, so that the rubber block 84 can be tightly pressed against the top edge of the processing material piece, thereby realizing the pressing and limiting of the processing material piece.

[0021] The bottom end of the spring 86 abuts against the inner sliding block 87 , and the top end of the spring 86 abuts against the top inner wall of the inner groove 85 .

[0022] A top hole communicating with the inner groove 85 is formed on the top surface of the T-shaped slide seat 81 , and the top hole corresponds to the connecting rod 88 , so that the connecting rod 88 can pass through smoothly.

[0023] Among them, four supporting feet are arranged at the bottom of the body 1, and the four supporting feet are respectively located at the four corners of the body 1, so that the body 1 can be placed more stably.

The top surface of the rubber block 84 is provided with an integrated insert block 841, and the end surface of the pressure strip 83 is provided with a socket 831 corresponding to the insert block 841. The top surface of the insert block 841 is symmetrically provided with a plurality of side clamp blocks 842 and a socket 831 corresponding to the insert block 841. There are two side clamping blocks 842, the top end of the plug block 841 passes through the insertion hole 831 to the top of the pressure strip 83, and the side clamping block 842 is clamped on the top surface of the pressure strip 83. When actually disassembling and assembling the rubber block 84, you only need to lift the pressure strip 83 first, and press the plug block 841 down hard, so that the side clamping block 842 is squeezed and elastically deformed, and the plug block 841 and the side clamping block 842 can be pushed out from the bottom end of the insertion hole 831, and the rubber block 84 can be removed from the bottom of the pressure strip 83.

[0027] Among them, the plug block 841 and the side clamp block 842 are an integrated structure, both of which are made of rubber material and will undergo elastic deformation when squeezed. Two elliptical cavities are opened in the plug block 841, so that the side clamp block 842 has sufficient deformation space when squeezed.
