Abstract
Description
Technical Field
[0001] This invention relates to the field of engraving equipment technology, and in particular to a high-precision engraving device. Background Technology
[0002] In fields such as precision manufacturing, jewelry processing, and electronic component production, high-precision engraving equipment is the core equipment for achieving refined processing of hard materials such as metals and ceramics. Its processing accuracy, operational stability, and degree of automation directly determine product quality and production efficiency. As the industry's requirements for product precision continue to increase, especially with the growing demand for engraving of products such as miniature metal parts and precision molds, existing high-precision engraving equipment is gradually revealing many technical shortcomings, making it difficult to meet the needs of efficient and precise processing.
[0003] Regarding chip removal, existing engraving equipment typically handles metal chips generated during processing using simple air blowing or fixed negative pressure adsorption. Air blowing often results in chips scattering everywhere, making thorough removal difficult and potentially scratching the workpiece surface, affecting engraving accuracy, and even splashing into the gaps between precision components like guide rails and spindles, accelerating wear. Fixed negative pressure adsorption often uses permanent magnet filters to separate magnetic chips, but these require periodic manual disassembly and cleaning, which is cumbersome and necessitates machine downtime, severely impacting continuous processing efficiency. Furthermore, fine chips remaining on the permanent magnet surface are difficult to remove completely, leading to a decline in filtration efficiency over time. These chips can then enter the negative pressure pipeline or blower with the airflow, causing blockages and equipment malfunctions. In addition, some equipment has poorly designed negative pressure adsorption areas, posing a risk of chips bypassing adsorption and directly entering the pipeline, further reducing the reliability of chip removal. Therefore, this application proposes a high-precision engraving device. Summary of the Invention

[0015] Compared with the prior art, the present invention has the following beneficial technical effects: This invention achieves precise three-dimensional positioning of the engraving head and the workpiece by activating a second motor to drive a second threaded rod to adjust the horizontal position of the positioning plate, a first motor to drive a first threaded rod to adjust the vertical height of the engraving head, and a third motor to drive a third threaded rod to adjust the horizontal position of the placement plate.

The airflow from the blower is received through the second connecting pipe and delivered into the guide block. The guide block blows air back and forth, blowing the debris on the placement plate to the other side to prevent debris from accumulating and affecting the carving.
[0017] Furthermore, air is extracted from the negative pressure tank through the air intake pipe to create a negative pressure. This is combined with energizing the electromagnetic device, which then generates magnetism on its surface. This causes the air outlet block to be blown into the negative pressure tank to attract metal debris. The rotation of the electromagnetic device further enhances the attraction of the debris. After the power is turned off, the electromagnetic device is driven by the second reciprocating screw to scrape off the debris from the surface. The debris that has fallen off is collected in a collection tank. With real-time monitoring by a pressure sensor, excessive debris from the collection tank is prevented from entering the negative pressure tank. The closed-loop air path avoids secondary pollution.
[0018] This invention enables centralized processing of debris, improves processing efficiency, increases equipment versatility, reduces maintenance costs, and improves engraving precision. Attached Figure Description

[0027] Example 1
[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 7As shown, the present invention proposes a high-precision engraving device, including a worktable 1 and a mounting column 2. The mounting column 2 is fixedly mounted on the worktable 1. A placement plate 3 is slidably mounted on the worktable 1 for placing the part to be engraved.

A second motor 7 is fixedly mounted on one side of the mounting column 2. The output shaft of the second motor 7 is fixedly connected to the second threaded rod 8.

A third threaded rod 24 is rotatably mounted on the worktable 1. The placement plate 3 is threadedly connected to the third threaded rod 24. Rotating the third threaded rod 24 moves the placement plate 3 horizontally. Slider 10s are symmetrically slidably mounted on the placement plate 3. A groove 13 is provided on the placement plate 3, and a positive and negative threaded rod 12 is rotatably mounted within the groove 13. The positive and negative threaded rod 12 is threadedly connected to the slider 10. A mounting plate 14 is fixedly mounted on one side of the slider 10, and a fixing plate 16 is slidably mounted on one side of the mounting plate 14. Multiple equally spaced rubber blocks 17 are fixedly mounted on the fixing plate 16. Rotating the positive and negative threaded rods 12 causes the sliders 10 to move closer together, and the mounting plate 14 on one side of the slider 10 moves accordingly. The fixing plate 16 on one side of the mounting plate 14 contacts the workpiece. The rubber block 17 fixes the workpiece to prevent it from moving during engraving and affecting the engraving accuracy. A third motor 25 is fixedly installed on the placement plate 3. The output shaft of the third motor 25 is fixedly connected to the third threaded rod 24. The second motor 7 drives the second threaded rod 8 to adjust the horizontal position of the positioning plate 46. The first motor 5 drives the first threaded rod 6 to adjust the vertical height of the engraving head 9. The third motor 25 drives the third threaded rod 24 to adjust the horizontal position of the placement plate 3, so as to achieve three-dimensional precise positioning of the engraving head 9 and the workpiece. The placement plate 3 is equipped with a cleaning mechanism to clean the debris generated by the engraving head 9 and the surface of the placement plate 3.
[0029] Example 2
[0030] like Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10As shown, the cleaning mechanism includes a blower 43 fixedly mounted on the engraving head 9. A first connecting pipe 22 is fixedly mounted on one side of the blower 43. A first mounting frame 18 is fixedly mounted on the placement plate 3. A guide block 20 is slidably mounted on the first mounting frame 18. A first reciprocating screw 19 is rotatably mounted on the first mounting frame 18. The first reciprocating screw 19 is threadedly connected to the guide block 20. The guide block 20 is a hollow structure. One end of the first connecting pipe 22 communicates with the guide block 20. An air outlet block 21 is fixedly mounted on one end of the guide block 20. The placement plate 3 is fixedly mounted with... A baffle 4 is provided. A negative pressure groove 33 is fixedly installed on one side of the placement plate 3. An electromagnetic device 31 is rotatably installed inside the negative pressure groove 33. The electromagnetic device 31 is cylindrical. A DC power supply 38 is fixedly installed on one side of the negative pressure groove 33. A connecting wire 39 is fixedly installed on the DC power supply 38 and electrically connected to the electromagnetic device 31. A collection groove 32 is slidably installed on the negative pressure groove 33 and is located at the bottom of the electromagnetic device 31. A guide plate 37 is fixedly installed inside the negative pressure groove 33. The guide plate 37 is inclined to prevent debris from falling onto the electromagnetic device 31. The air directly enters the negative pressure tank 33. One end of the blower 43 is fixedly equipped with an air inlet pipe 42, which connects to the negative pressure tank 33. During engraving, the blower 43 is started, rotating the first reciprocating screw 19. The first reciprocating screw 19, along with the guide block 20, performs a horizontal reciprocating motion on the first mounting frame 18. The blower 43 delivers air through the first connecting pipe 22 to the guide block 20, and then it is ejected from the outlet block 21. Combined with the reciprocating motion of the guide block 20, this blows the debris generated during engraving on the placement plate 3 to one side. When the blower 43 blows air to one side... When the material is conveyed into the first connecting pipe 22, the air inlet pipe 42 on the other side draws out the air inside the negative pressure tank 33 and conveys it into the blower 43, forming a negative pressure. At this time, the debris is attracted into the negative pressure tank 33. Rotating the electromagnetic device 31 connects the electromagnetic device 31 to the DC power supply 38. At this time, the surface of the electromagnetic device 31 generates magnetism, attracting the metal debris generated during engraving. As the electromagnetic device 31 rotates, the attraction effect of the electromagnetic device 31 on the metal debris is improved, preventing the debris from entering the negative pressure tank and being sucked into the blower 43, thus affecting the normal use of the blower 43.
[0031] like Figure 5-6As shown, a second mounting frame 26 is fixedly installed on the negative pressure trough 33. A second reciprocating screw 28 is rotatably installed inside the second mounting frame 26. A guide block 27 is slidably installed inside the second mounting frame 26. The second reciprocating screw 28 is threadedly connected to the guide block 27. A scraper 30 is slidably installed at the bottom of the guide block 27. The scraper 30 is arc-shaped, and its bottom is in contact with the electromagnetic device 31. A top plate 48 is slidably installed inside the collection trough 32. A pressure sensor 49 is fixedly installed at the bottom of the top plate 48. A controller is installed inside the negative pressure trough 33. The output end of the pressure sensor 49 is connected to the input end of the controller. The output end of the controller is connected to the starting end of the sixth motor 34, the seventh motor 35, the electric telescopic rod 36, the blower 43, and the fifth motor 23. An electric telescopic rod 36 is fixedly installed on one side of the negative pressure trough 33. The telescopic shaft contacts one end of the collection trough 32. Rotating the second reciprocating screw 28 causes the guide block 27 to reciprocate horizontally within the second mounting frame 26, de-energizing the electromagnetic device 31. At this time, the magnetism of the electromagnetic device 31 disappears, and some debris falls into the collection trough 32 as the magnetism disappears. The guide block 27 drives the scraper 30 at the bottom to scrape off the remaining debris on the surface of the electromagnetic device 31, which is then collected by the collection trough 32. When there is too much debris in the collection trough 32, the pressure sensor 49 transmits a signal to the controller. The controller stops the fifth motor 23, the sixth motor 34, and the seventh motor 35, shuts off the blower 43, and starts the electric telescopic rod 36. The telescopic shaft of the electric telescopic rod 36 pushes the mounting trough 41 out of the negative pressure trough 33, making it easier to remove the collection trough 32 and process the debris in it.
[0032] Example 3
[0033] like Figure 1-8 As shown, a connecting cavity 47 is fixedly installed at the bottom of the engraving head 9. The connecting cavity 47 is a hollow cavity. Multiple nozzles 45 arranged in a circular pattern at equal intervals are fixedly installed at the bottom of the connecting cavity 47. A second connecting pipe 44 is fixedly installed on one side of the blower 43. One end of the second connecting pipe 44 is connected to the connecting cavity 47. When the blower 43 is started, part of the airflow is delivered to the nozzles 45 through the second connecting pipe 44 to blow away the debris at the engraving area and cool down the engraving head 9. A fourth motor 11 is fixedly installed on one side of the placement plate 3. The output shaft of the fourth motor 11 is fixedly connected to the positive and negative thread screw 12. A fifth motor 23 is fixedly installed on one end of the second mounting frame 26. The output shaft of the fifth motor 23 is fixedly connected to the first reciprocating thread screw 19. A sixth motor 34 is fixedly installed on one side of the negative pressure groove 33. The output shaft of the sixth motor 34 is fixedly connected to the second reciprocating thread screw 28. A seventh motor 35 is fixedly installed on one side of the negative pressure groove 33. The output shaft of the seventh motor 35 is fixedly connected to the electromagnetic device 31.
[0034] like Figure 4-9As shown, a first spring 15 is fixedly installed on one side of the mounting plate 14. One end of the first spring 15 is fixedly connected to the fixed plate 16. A second spring 29 is fixedly installed at the bottom of the guide block 27. One end of the second spring 29 is fixedly connected to the scraper 30. An installation groove 41 is provided on the negative pressure groove 33. The electromagnetic device 31 is located in the installation groove 41. A pull plate 40 is fixedly installed at one end of the electromagnetic device 31. The electromagnetic device 31 is composed of an electromagnetic coil and a magnetic core. The magnetic core is made of silicon steel sheets with high magnetic permeability. The coil is wound around the outside of the core and the whole is encapsulated in a non-magnetic stainless steel shell. The current passes through the coil to generate a magnetic field. After the magnetic field is strengthened by the magnetic core, a high-intensity and high-uniformity magnetic attraction area is formed in the flow channel of the device.
[0035] Working principle: The metal workpiece to be engraved is placed on the placement plate 3. The fourth motor 11 is started, which drives the positive and negative threaded screws 12 to rotate. The positive and negative threaded screws 12 drive the sliders 10 to move closer to each other. The mounting plate 14 on one side of the sliders 10 moves together, and the fixing plate 16 on one side of the mounting plate 14 contacts the workpiece. The rubber block 17 on the fixing plate 16 fixes the workpiece to prevent it from moving during engraving and affecting the engraving accuracy. The first reciprocating screw 19 is rotated. The first reciprocating screw 19, along with the guide block 20, makes a horizontal reciprocating motion on the first mounting frame 18, causing the drum to... The blower 43 delivers air through the first connecting pipe 22 to the guide block 20, and then ejects it from the outlet block 21. Combined with the reciprocating motion of the guide block 20, this blows the debris generated during engraving on the placement plate 3 to one side. While the blower 43 delivers gas into the first connecting pipe 22 on one side, the intake pipe 42 on the other side draws air out of the negative pressure groove 33 and delivers it into the blower 43, creating a negative pressure. At this time, the debris is attracted into the negative pressure groove 33. Rotating the electromagnetic device 31 connects it to the DC power supply 38, causing the surface of the electromagnetic device 31 to become magnetic, thus attracting the engraved debris. The electromagnetic device 31 is used to adsorb metal debris. As the electromagnetic device 31 rotates, its adsorption effect on the metal debris is improved, preventing debris from entering the negative pressure tank and being sucked into the blower 43, thus affecting its normal operation. The second reciprocating screw 28 is rotated, causing the guide block 27 to reciprocate horizontally within the second mounting frame 26, thus de-energizing the electromagnetic device 31. At this point, the magnetism of the electromagnetic device 31 disappears, and some debris falls into the collection tank 32 as the magnetism fades. The guide block 27 then drives the scraper 30 at the bottom to clean the surface of the electromagnetic device 31. The residual debris is scraped off and collected in the collection tank 32. When there is too much debris in the collection tank 32, the pressure sensor 49 transmits a signal to the controller. The controller controls the fifth motor 23, the sixth motor 34 and the seventh motor 35 to stop, shuts off the blower 43, and starts the electric telescopic rod 36. The telescopic shaft of the electric telescopic rod 36 pushes the mounting slot 41 out of the negative pressure slot 33, making it easier to remove the collection tank 32 and process the debris in the collection tank 32. This achieves centralized processing of debris, improves processing efficiency, increases equipment versatility, reduces maintenance costs and improves engraving accuracy.
