Technical Field

[0001] This utility model belongs to the field of engraving machine technology, specifically relating to an engraving machine with protective functions. Background Technology

[0002] A CNC engraving machine is a professional CNC machining equipment, belonging to the category of CNC machine tools. It uses a high-speed rotating spindle to drive cutting tools and perform precise engraving and milling operations on workpieces placed on a worktable according to preset programs and parameters. CNC engraving machines are usually equipped with advanced control systems and precision mechanical structures, featuring high precision, high efficiency, and good stability. They can meet the processing requirements of various complex shapes and small sizes and can be used to process a variety of materials such as aluminum alloy, copper, steel, acrylic, and ceramics.

[0003] Currently, CNC engraving machines are equipped with protective covers to effectively prevent the flying of chips during the cutting process. The cutting operation is completed inside the cover. However, the process of taking out and placing the workpiece is quite cumbersome. The operator must first open the cover door and then move the shelf to take out the processed workpiece. This not only slows down the overall process but also seriously restricts the efficient processing of the workpiece. Therefore, a CNC engraving machine with protective function is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a precision engraving machine with a protective function that allows the door to open and close during the movement of the shelf to solve the above problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A protective engraving machine includes a main body and a protective cover mounted on the main body. A shelf is slidably mounted on the main body. The machine also includes:

[0007] A drive motor is mounted on the main body of the engraving machine, and a drive screw is provided at the output end of the drive motor. The placement plate slides on the main body of the engraving machine via the drive screw.

[0008] A bidirectional lead screw is rotatably mounted on the main body of the engraving machine, and is driven to move by a drive screw.

[0009] The gate is threaded on both sides of the bidirectional lead screw. When the bidirectional lead screw is actuated, it drives the gate to move in opposite directions or towards each other.

[0010] As a further optimization of this utility model, a sliding seat is provided on the lower surface of the shelf, and the shelf is slidably connected to the main body of the engraving machine through the sliding seat. The sliding seat is threadedly connected to the drive screw, and the drive screw is rotatably disposed in the main body of the engraving machine. Telescopic covers and accordion covers are respectively provided on both sides of the shelf, and the telescopic covers and accordion covers are respectively connected to both sides of the inner surface of the main body of the engraving machine.

[0011] As a further optimization of this utility model, the main body of the engraving machine is provided with a sliding groove, the cover is slidably disposed in the sliding groove, the bidirectional lead screw is rotatably disposed in the sliding groove, and a guard plate is provided on one side of the bidirectional lead screw.

[0012] As a further optimization of this utility model, the drive screw passes through the guard plate, the highest point of the guard plate is higher than the shelf, and a horizontal axis is rotatably provided on the inner surface of the guard plate.

[0013] As a further optimization of this utility model, both the horizontal shaft and the drive screw are provided with synchronous pulleys, and a synchronous belt is provided between the synchronous pulleys. Both the horizontal shaft and the bidirectional lead screw are provided with bevel gears, and the bevel gears mesh with each other.

[0014] As a further optimization of this utility model, a threaded sleeve is provided on the lower surface of the cover, the threaded sleeve is threadedly connected to a bidirectional lead screw, a pulley is rotatably provided on the upper end of the cover, and a linear track is fixedly provided on the protective cover, the pulley and the linear track are tumbled together.

[0015] The beneficial effects of this utility model are as follows:

[0016] Unlike existing technologies, in actual use, the drive motor drives the drive screw, enabling the shelf to slide automatically, facilitating the placement and removal of items. Simultaneously, the drive screw, through a synchronous belt and bevel gear transmission, drives a bidirectional screw to rotate, achieving automatic opening and closing of the cover. When the shelf slides outward, the cover automatically moves in opposite directions to open; when the shelf slides inward to begin precision engraving, the cover automatically moves in opposite directions to close, effectively preventing debris from splashing out during processing. This ensures operator safety, reduces environmental pollution, and significantly improves the protective performance and overall work efficiency of the engraving machine. Attached Figure Description

Detailed Implementation

[0024] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0025] Example 1

[0026] like Figure 1 - Figure 6 As shown, a CNC engraving machine with protective functions includes a CNC engraving machine body 1 and a protective cover 2 disposed on the CNC engraving machine body 1. A shelf 3 is slidably disposed on the CNC engraving machine body 1, and the machine also includes:

[0027] A drive motor 4 is mounted on the main body 1 of the engraving machine. A drive screw 41 is provided at the output end of the drive motor 4. The placement plate 3 slides on the main body 1 of the engraving machine via the drive screw 41.

[0028] The bidirectional lead screw 7 is rotatably mounted on the main body 1 of the engraving machine and is driven to move by the drive screw 41.

[0029] The gate 8 is threaded on both sides of the bidirectional lead screw 7. When the bidirectional lead screw 7 is activated, it drives the gate 8 to move in opposite directions or towards each other.

[0030] A sliding seat 31 is provided on the lower surface of the shelf 3. The shelf 3 is slidably connected to the main body 1 of the engraving machine through the sliding seat 31, which ensures the stability and accuracy of the shelf 3 sliding on the main body 1 of the engraving machine. The sliding seat 31 is threadedly connected to the drive screw 41. The drive screw 41 is rotatably set in the main body 1 of the engraving machine. In this way, the drive motor 4 serves as a power source, and its output end is connected to the drive screw 41, which can convert the rotational motion of the motor into linear motion and precisely control the sliding of the shelf 3. A telescopic cover 43 and a bellows cover 42 are respectively provided on both sides of the shelf 3. The telescopic cover 43 and the bellows cover 42 are respectively connected to the inner surface of the main body 1 of the engraving machine. The telescopic cover 43 and the bellows cover 42 protect the drive screw 41 and prevent the debris generated during the engraving process from falling onto the drive screw 41.

[0031] The main body 1 of the engraving machine is provided with a sliding groove 11, the cover door 8 is slidably disposed in the sliding groove 11, and the bidirectional lead screw 7 is rotatably disposed in the sliding groove 11. When the bidirectional lead screw 7 rotates, it can drive the cover door 8 to move back and forth or towards each other to realize automatic opening and closing. A guard plate 12 is provided on one side of the bidirectional lead screw 7.

[0032] The drive screw 41 passes through the guard plate 12, and the highest point of the guard plate 12 is higher than the shelf 3, thus providing good protection. It can block foreign objects such as debris generated during processing, preventing them from entering the transmission components such as the bidirectional screw 7. A horizontal shaft 6 is rotatably mounted on the inner surface of the guard plate 12. Both the horizontal shaft 6 and the drive screw 41 are equipped with synchronous pulleys 51, and a synchronous belt 5 is connected between the synchronous pulleys 51. The synchronous belt 5 connects the drive screw 41 and the horizontal shaft 6, enabling synchronous rotation between them. Both the horizontal shaft 6 and the bidirectional screw 7 are equipped with bevel gears 61, which mesh with each other. The use of bevel gears 61 enables the redirection of power, converting the rotation of the horizontal shaft 6 into the rotation of the bidirectional screw 7.

[0033] A threaded sleeve 82 is provided on the lower surface of the cover 8, which is threadedly connected to the bidirectional lead screw 7. A pulley 81 is rotatably provided on the upper end of the cover 8, and a linear track 83 is fixedly provided on the protective cover 2. The pulley 81 is tumbledly connected to the linear track 83. At the same time, the cover 8 is slidably disposed in the sliding groove 11. This allows the cover 8 to move smoothly in the sliding groove 11 under the drive of the bidirectional lead screw 7. When the engraving machine is working, the closed cover 8 can effectively block the processing debris and prevent it from splashing out and causing harm to the surrounding environment and personnel. When the shelf 3 enters or exits, the automatically opened cover 8 facilitates operation and improves work efficiency.

[0034] It should be noted that the working principle of this protective engraving machine is as follows: When an item needs to be engraved, the drive motor 4 set on the main body 1 of the engraving machine is started. The drive motor 4 drives the drive screw 41 at the output end to rotate. Since the sliding seat 31 on the lower surface of the placement plate 3 is threadedly connected to the drive screw 41, the placement plate 3 will slide on the main body 1 of the engraving machine through the sliding seat 31. The telescopic cover 43 and the bellows cover 42 on both sides of the placement plate 3 will extend and retract with the movement of the placement plate 3, which plays a protective role.

[0035] During the rotation of the drive screw 41, the synchronous wheel 51 on the drive screw 41 drives the synchronous wheel 51 on the horizontal shaft 6 to rotate through the synchronous belt 5, thereby causing the horizontal shaft 6 to rotate. The horizontal shaft 6 meshes with the bevel gear 61 on the double-acting screw 7, thereby driving the double-acting screw 7 to rotate in the sliding groove 11. The threaded sleeve 82 on the lower surface of the cover 8 is threadedly connected to the double-acting screw 7, and the pulley 81 at the upper end of the cover 8 is rollingly connected to the linear track 83 on the protective cover 2. When the double-acting screw 7 rotates, it will drive the cover 8 to move back and forth or towards each other in the sliding groove 11. When the shelf 3 slides outward, the cover 8 moves back and forth to open, making it convenient to place or take out items. When the shelf 3 slides inward to start fine carving, the cover 8 moves towards each other to close, which can prevent debris and other debris from splashing out during the processing.

[0036] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
