The front of the base 1 is fixedly connected with a controller 21.

[0032] Reference Figure 2 - Figure 4 The positioning mechanism also includes a vertically arranged transmission rod 6, which is fixedly mounted on the top of the output shaft of the electric cylinder 5. A movable plate 7 is fixedly connected to the top of the transmission rod 6, and the movable plate 7 is set to be U-shaped. A wedge block 8 is fixedly connected to the top of the movable plate 7. The number of wedge blocks 8 is set to two groups, and the cross-section of the wedge block 8 is set to be triangular. The positioning mechanism also includes a clamping block 9, which is slidably mounted on the inner wall of the base 1. A control groove 10 is opened at the bottom of the clamping block 9. The number of control grooves 10 is equal to the number of wedge blocks 8. The inner wall of the control groove 10 is provided with an inclined surface. The positioning mechanism also includes a spring 11. The number of clamping blocks 9 is set to two groups. The sides of the two groups of clamping blocks 9 that are close to each other are elastically connected to the inner wall of the base 1 through the spring 11.

[0034] Reference Figure 1 - Figure 3 The collecting mechanism includes a collecting box 19 for collecting waste generated during the engraving work. A feeding chute 17 is provided on the top of the base 1 for facilitating the waste to slide into the collecting chamber 18. A collecting chamber 18 is provided inside the base 1. The collecting box 19 is plugged into the inner wall of the collecting chamber 18. The collecting mechanism also includes a handle 20 for facilitating the staff to take out the collecting box 19.

The waste generated during the processing slides from the feeding chute 17 into the collecting chamber 18, so as to avoid the waste from accumulating on the top of the base 1, affecting the accuracy of subsequent engraving processing work, and improving the processing quality of the product.

[0035] Working principle: When in use, by starting the power supply of the linear guide 15, the slider 16 is displaced along the working direction of the linear guide 15, and the workpiece is transported from the initial position to the working position below the woodworking engraving machine body 4, and then the power supply of the electric cylinder 5 is started, and the electric cylinder 5 works to drive the transmission rod 6 to move upward, and the displacement of the transmission rod 6 drives the movable plate 7 to move upward, and the displacement of the movable plate 7 drives the wedge block 8 to move upward, and the displacement of the wedge block 8 squeezes the inclined surface of the control groove 10, so that the two groups of clamping blocks 9 overcome the elastic force of the spring 11 and approach each other until the two groups of clamping blocks 9 contact the surface of the workpiece through the semicircular block 13, and push the workpiece to the center of the working range at the bottom of the woodworking engraving machine body 4, so as to improve the positioning accuracy. At the same time, when the semicircular block 13 contacts the surface of the workpiece, the semicircular block 13 will perform an adaptive small range rotation according to the shape of the surface of the workpiece, so that the semicircular block 13 fits the surface of the workpiece more closely, improves the stability of the clamping, and further improves the processing accuracy and quality.

[0036] The waste generated by the engraving work enters the collection chamber 18 through the discharge chute 17 and falls into the collection box 19. When the waste in the collection box 19 needs to be cleaned, the handle 20 is pulled outward to drive the collection box 19 to move outward, and then the collection box 19 is conveniently and quickly taken out from the collection chamber 18, and the waste is processed in a centralized manner, thereby improving work efficiency and reducing the possibility of waste particles accumulating on the top of the base 1 and affecting the processing quality.
