DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. 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.

[0027] See also Figure 1-Figure 5 The utility model provides a technical solution: a clamp for an engraving machine, including a workbench 1 and a collection box 5. The bottom of the workbench 1 is fixedly connected with pillars 4, and the pillars 4 support the workbench 1 so that it can be firmly placed on the ground. The design of the pillars takes into account stability and load-bearing capacity to ensure that the entire clamp will not shake or tilt during operation. A collection port 9 is provided in the middle of the workbench 1, which is located in the middle of the workbench 1, so that the waste generated during the engraving process can fall directly into the collection box 5 without additional cleaning, thereby improving work efficiency. The collection box 5 is arranged below the middle of the workbench 1, and the collection box 5 is used to collect the waste generated during the engraving process to keep the working environment clean. A box door 501 is hinged on the front of the collection box 5, and a handle 502 is fixedly connected to the right side of the front of the box door 501. Through the design of the box door 501 and the handle 502, the operator can easily open the box door 501 to clean or recycle the waste. A screening mechanism is arranged inside the collection box 5, and a fixing mechanism is arranged on the upper surface of the workbench 1;

[0028] The fixing mechanism comprises a width adjustment unit and a height adjustment unit. There are two groups of the fixing mechanism, which are respectively arranged on both sides of the upper surface of the workbench 1 .

[0029] The width adjustment unit includes a slide 101, a slide 202, a baffle 201, a slider 202, a connection block 203, a screw rod 204 and a turning handle 205. The slide 101 and the slide 202 are respectively opened on the front and rear sides of the left side of the workbench 1, providing sliding tracks for the slider 202 and the screw rod 204, ensuring that the width adjustment unit can be smoothly moved and fixed. The bottom of the slider 202 is slidably connected to the inside of the slide 101, the screw rod 204 is arranged inside the slide 202, one end of the screw rod 204 is rotatably connected to the left side of the inner wall of the slide 202, and the other end of the screw rod 204 extends outward and is fixedly connected to the turning handle 205. The connection block 103 is threadedly connected to the screw rod 204. By turning the turning handle 205, the screw rod drives the connection block 103 to move, thereby adjusting the position of the baffle 201 to adapt to workpieces of different sizes. The bottom of the baffle 201 is fixedly connected to the upper surface of the slider 202 and the connecting block 1 203. The baffle 201 serves as a supporting part of the fixing mechanism and is connected to the height adjustment unit to ensure that the workpiece is stably clamped.

[0030] The height adjustment unit includes a rotating bar 601, a second motor 602, a fixed block 603, a slide groove three 604, a threaded rod 605, a clamp plate one 606, a clamp plate two 607 and a connecting block two 608. One end of the rotating bar 601 rotates on the baffle 201, one side of the fixed block 603 is fixedly connected to the other end of the rotating bar 601, and the slide groove three 604 is opened on the other side of the fixed block 603. The top end of the threaded rod 605 is rotatably connected to the top end inside the slide groove three 604 and extends outward and is fixedly connected to the output end of the second motor 602. The second motor 602 drives the threaded rod 605 to rotate, thereby driving the connecting block two 608 and the clamp plate two 607 to move up and down, thereby realizing the height adjustment of the workpiece. The bottom end of the threaded rod 605 is fixedly connected to the inner ring of the bearing behind the first clamp plate 606, the middle part of the second connecting block 608 is threadedly connected to the threaded rod 605, the back of the second clamp plate 607 is fixedly connected to the front of the second connecting block 608, and the surfaces of the first clamp plate 606 and the second clamp plate 607 that are close to each other are provided with threads. The thread design enhances the friction between the workpiece and ensures that the workpiece will not move during the processing.

[0031] A support plate 301 is fixedly connected to the right side of the baffle 201 on the right side of the workbench 1. The bottom of the first motor 302 is fixedly connected to the upper surface of the baffle 201. The output end of the first motor 302 is fixedly connected to one end of the rotating bar 601. The first motor 302 is driven to realize the rotation of the fixing mechanism, which is convenient for adjusting the angle of the workpiece.

[0032] The screening mechanism includes a support block 701, a magnetic block 702, a fixed plate 703, a fan 704, a cylinder 705, a partition plate 8 and an outlet 801. The support block 701 is fixedly connected to the left wall inside the collection box 5. The support block 701 ensures that the magnetic block 702, the fixed plate 703 and the fan 704 and other components can be stably installed inside the collection box 5. The partition plate 8 is fixedly connected to the right inside the collection box 5, the left side of the magnetic block 702 is fixedly connected to the upper surface of the support block 701, and the right side of the magnetic block 702 is fixedly connected to the left side of the partition plate 8. The magnetic block 702 can absorb the metal waste generated during the engraving process. The cylinder 705 is fixedly connected to the surrounding of the magnetic block 702, and the output end of the cylinder 705 is fixedly connected to the surrounding of the lower surface of the fixed plate 703. The suction force of the magnetic block 702 passes through the fixed plate 703, so that it absorbs the metal waste. When the cylinder 705 pushes the fixed plate 703 to rise, the magnetic force disappears, which is convenient for cleaning the metal debris on it. The bottom of the fan 704 is fixedly connected to the left side of the upper surface of the fixed plate 703, and the bottom of the fan 704 is fixedly connected to the left side of the upper surface of the magnetic block 702 to blow away non-metallic debris and further separate different types of waste. The outlet 801 is opened on the partition plate 8 to facilitate the recycling of classified waste.

[0033] Working principle: First, place the workpiece on the workbench 1 of the fixture. Then, according to the size and shape of the workpiece, by turning the handle 205, the screw rod 24 drives the connecting block 203 to move, thereby adjusting the position of the baffle 201 to adapt to workpieces of different sizes. Then, the second motor 602 drives the threaded rod 605 to rotate, driving the clamping plate to move up and down, thereby fixing the height of the workpiece. At the same time, the threaded design on the clamping plate enhances the friction between the workpiece and the clamping plate, ensuring that the workpiece will not move during the processing process.

[0034] Start the engraving machine and start processing the workpiece. The waste generated during the processing will fall into the collection box 5 through the collection port 9. The screening mechanism in the collection box 5 is responsible for classifying the waste. The magnetism of the magnetic block 702 absorbs the metal waste through the fixed plate 703, and the fan 704 blows away the non-metallic debris and enters the right side of the partition plate 8 through the outlet 801. The telescopic function of the cylinder 705 allows the fixed plate 703 to move up and down. When the fixed plate 703 rises, the magnetism disappears. When the waste in the collection box 5 accumulates to a certain extent, the box door 501 can be opened to clean or recycle the waste.
