Description

Technical Field

[0001] The utility model belongs to the technical field of engraving machines, and in particular relates to a high-precision metal model engraving machine. Background Art

[0002] Metal laser engraving machines use laser beams to precisely remove specific parts of metal materials to achieve the desired pattern or logo. During the metal engraving process, the laser beam functions like a chisel in traditional engraving, which can precisely remove material.

[0003] At present, when a metal engraving machine is engraving, the engraving tool head is usually moved directly on the metal surface to complete the engraving, thereby producing a pattern or text with a three-dimensional effect. Due to the different hardnesses of different metal materials, the engraving tool head will generate a high temperature during the operation. In order to reduce the temperature of the tool head and prevent the metal powder generated during the processing from splashing, water is usually used for cooling and cleaning;

[0004] However, existing metal engraving machines have shortcomings in the treatment of spray water and metal powder. Spray water and metal powder often cannot be effectively recycled, which not only causes a waste of resources but also may pollute the environment. In addition, if the metal model is not properly fixed during the processing process, it is prone to shaking, which affects the accuracy and effect of the engraving. Utility Model Content

[0005] The utility model provides a high-precision metal model engraving machine, aiming to solve the problem that the existing metal engraving machine spray cooling fails to effectively recycle the spray water and metal chips, resulting in a waste of resources and possibly causing environmental pollution. In addition, the metal model is not properly fixed during the processing and is prone to shaking, thereby affecting the precision and effect of the engraving.

[0006] The utility model is implemented as follows: a high-precision metal model engraving machine comprises an operating table; a plurality of water discharge grooves arranged on the upper surface of the operating table; a filter chamber connected to the plurality of water discharge grooves is provided in the operating table; a group of longitudinal screw slides symmetrically arranged on both sides of the upper surface of the operating table; a connecting plate arranged at the movable ends of the two longitudinal screw slides; a transverse screw slide arranged between the two connecting plates; a receiving block arranged at the movable end of the transverse screw slide; spray shields arranged on both sides of the lower position of the receiving block; a water storage tank arranged above the transverse screw slide; a spray head arranged on the inner side of one of the spray shields, the water storage tank and the spray head are connected through a first flexible pipe; the water storage tank and the filter chamber are connected through a second flexible pipe.

[0007] Preferably, a partition plate is provided in the filter cavity, the partition plate divides the filter cavity into two cavities, and an inclined first filter screen is provided between the partition plate and one of the cavities.

[0008] Preferably, the operating table is connected to a slag collecting box at an outer position adjacent to another of the cavities.

[0009] Preferably, a carving knife is arranged at the middle position of the bottom side of the receiving block, and a driving cylinder is arranged above the receiving block, and the output end of the driving cylinder penetrates the receiving block and is fixedly connected with the end key of the carving knife.

[0010] Preferably, the opposite side walls of the two longitudinal screw slides are each provided with an electric push rod, the output ends of the two electric push rods are each provided with a limit plate, and the opposite side of the two limit plates are each provided with a rubber pad.

[0011] Preferably, a second filter screen is provided at an upper position of the inner cavity of the water storage tank.

[0012] Compared with the prior art, the embodiments of the present application have the following beneficial effects:

[0013] First, by setting up a sprinkler head and spraying in the processing area, the engraving tool is effectively cooled to prevent it from overheating, thereby ensuring processing accuracy and extending the service life of the engraving tool. In addition, the coolant can prevent the processed material from deforming due to high temperature and help remove metal chips and dust generated during the processing. What is more worth mentioning is that the coolant and metal chips generated during the engraving process are filtered through the filter cavity, the filtered coolant is recycled, and the metal chips are collected in a centralized manner, which not only improves the efficiency of resource utilization, but also reflects the environmental protection design concept.

[0014] Secondly, the workpiece is firmly fixed between the two limit plates, which ensures the stability of the workpiece during the processing. This stability is crucial to ensuring the processing accuracy. At the same time, the cooperation of multiple screw slides enables the engraving tool to change its position at multiple angles, thereby increasing the complexity and diversity of engraving. The combination of these two not only improves the processing accuracy, but also significantly improves the processing efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by technicians in the technical field of this application; the terms used in the specification of the application herein are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0021] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0022] The utility model embodiment provides a high-precision metal model engraving machine, such as Figure 1-4 As shown, it includes an operating table 1; a plurality of water discharge grooves 2 arranged on the upper surface of the operating table 1; a filter chamber connected to the plurality of water discharge grooves 2 is opened in the operating table 1; a group of longitudinal screw slides 3 symmetrically arranged on both sides of the upper surface of the operating table 1; a connecting plate 4 arranged at the movable ends of the two longitudinal screw slides 3; a transverse screw slide 5 arranged between the two connecting plates 4; a receiving block 7 arranged at the movable end of the transverse screw slide 5; spray shields 8 arranged on both sides of the lower position of the receiving block 7; a water storage tank 9 arranged above the transverse screw slide 5; a spray head 10 arranged on the inner side of one of the spray shields 8, the water storage tank 9 and the spray head 10 are connected through a first flexible pipe 11; the water storage tank 9 is connected to the filter chamber through a second flexible pipe 6.

[0023] It should be noted that since the existing metal engraving machine spray cooling does not effectively recycle the spray water and metal chips, it causes a waste of resources and may also cause pollution to the environment. In addition, the metal model is not properly fixed during the processing process and is prone to shaking, which affects the accuracy and effect of the engraving. This solution combines the cooling of the engraving knife 15 by the spray head 10, the fixation of the workpiece by the limit plate 18, and the coordination of the screw slide. The entire engraving processing system not only ensures high-precision processing quality, but also significantly improves processing efficiency. Especially in terms of environmental protection design, the filtering and recycling of coolant and metal chips by the filter chamber not only realizes the effective utilization of resources, but also reflects the environmentally friendly design concept.

[0024] Specifically, in this embodiment, this scheme mainly includes an operating table 1; a plurality of water discharge grooves 2 arranged on the upper surface of the operating table 1; a filter chamber connected to the plurality of water discharge grooves 2 is opened in the operating table 1; when the engraving tool 15 is working, the coolant is transported to the spray head 10 through the water storage tank 9 and the flexible pipe, and sprayed from the spray head 10 to the processing area. The main function of the coolant is to cool the engraving tool 15 to prevent the engraving tool 15 from overheating during high-speed operation, thereby ensuring the processing accuracy and extending the service life of the engraving tool 15. In addition, the coolant can also effectively prevent the processed material from being deformed due to high temperature and ensure the processing quality. At the same time, the coolant in the processing area can also help remove metal chips and dust generated during the processing. If these metal chips and dust are allowed to accumulate in the processing area, they may not only affect the processing quality, but also cause damage to other parts of the machine. The spray shield 8 is designed below the receiving block 7. Its main function is to prevent the metal chips and coolant generated during the processing from splashing around, ensuring the cleanliness and safety of the processing environment.

[0025] The coolant and metal chips generated during the engraving process flow into the filter chamber through the water channel 2 on the operating table 1. The filter chamber is used to filter out large particles of metal chips to prevent these metal chips from entering the water tank 9 and causing blockage. The filtered coolant flows back to the water tank 9 through the flexible pipe, thereby realizing the recycling of the coolant and improving the efficiency of resource utilization. The large particles of metal chips intercepted by the first filter screen 13 fall into the slag box 14. When the metal chips accumulate to a certain extent, the slag box 14 can be opened for cleaning, thereby maintaining the continuous and efficient operation of the machine.

[0026] In a further preferred embodiment of the present invention, Figure 3 As shown, a partition plate 12 is arranged in the filter cavity, and the partition plate 12 divides the filter cavity into two cavities. A first filter screen 13 is arranged obliquely between the partition plate 12 and one of the cavities.

[0027] In this embodiment, after the coolant and metal chips flow into the filter chamber through the downhole trough 2, they will first encounter the inclined first filter screen 13. Due to the inclined design of the filter screen, large particles of metal chips will be effectively intercepted by the filter screen and deposited on the filter screen. As the metal chips accumulate, they will slide along the inclined filter screen into the cavity on the other side of the partition plate 12, which is convenient for subsequent cleaning and processing, while smaller particles and coolant will continue to flow through the mesh of the first filter screen 13 and be transported to the water tank 9.

[0028] In a further preferred embodiment of the present invention, Figure 2-3 As shown, the operating table 1 is connected to a slag collecting box 14 at an outer position adjacent to another cavity.

[0029] In this embodiment, the design of the slag collecting box 14 allows the metal chips deposited on the first filter screen 13 to smoothly slide down and fall into the slag collecting box 14, thereby achieving centralized collection and processing of the metal chips.

[0030] In a further preferred embodiment of the present invention, Figure 1-4 As shown, a carving knife 15 is arranged at the middle position of the bottom side of the receiving block 7, and a driving cylinder 16 is arranged above the receiving block 7. The output end of the driving cylinder 16 penetrates the receiving block 7 and is fixedly connected with the end key of the carving knife 15.

[0031] In this embodiment, the driving cylinder 16 directly drives the carving tool 15 to move up and down through the extension and retraction action of the piston rod.

[0032] In a further preferred embodiment of the present invention, Figure 1-3 As shown, the opposite side walls of the two longitudinal screw slides 3 are each provided with an electric push rod 17 , the output ends of the two electric push rods 17 are each provided with a limit plate 18 , and the opposite side of the two limit plates 18 are each provided with a rubber pad 19 .

[0033] In this embodiment, when the workpiece is placed between the two longitudinal screw slides 3, the electric push rod 17 will extend and push the limit plate 18 to move toward the workpiece. After the rubber pad 19 contacts the workpiece, the workpiece will be firmly fixed between the two limit plates 18 due to the elasticity and friction of the rubber. In this way, when the engraving machine is processing, the workpiece can maintain a stable position, thereby improving the processing accuracy and efficiency.

[0034] In a further preferred embodiment of the present invention, Figure 3 As shown, a second filter screen 20 is provided at the upper position of the inner cavity of the water storage tank 9.

[0035] In this embodiment, by arranging a second filter screen 20 at the upper position of the inner cavity of the water storage tank 9, smaller impurities can be further filtered out, thereby improving the purity of the water in the water storage tank 9.

[0036] Working principle: After the workpiece is placed between the two longitudinal screw slides 3, the electric push rod 17 will extend to push the limit plate 18 to move toward the workpiece; when the rubber pad 19 contacts the workpiece, the workpiece will be firmly fixed between the two limit plates 18 due to the elasticity and friction of the rubber; in this way, when the engraving machine is processing, the workpiece can maintain a stable position, thereby improving the processing accuracy and efficiency;

[0037] The cooperation of the two longitudinal screw slides 3 and the transverse screw slide 5 enables the engraving tool 15 to change its position at multiple angles; the driving cylinder 16 directly drives the up and down movement of the engraving tool 15 through the telescopic action of the piston rod; when the engraving tool 15 is working, the coolant is transported to the spray head 10 through the water storage tank 9 and the flexible pipe, and sprayed from the spray head 10 to the processing area; the main function of the coolant is to cool the engraving tool 15 to prevent the engraving tool 15 from overheating during high-speed operation, thereby ensuring the processing accuracy and extending the service life of the engraving tool 15; in addition, the coolant can also effectively prevent the processed material from being deformed due to high temperature and ensure the processing quality; at the same time, the coolant in the processing area can also help remove metal chips and dust generated during the processing; if these metal chips and dust are allowed to accumulate in the processing area, they may not only affect the processing quality, but also cause damage to other parts of the machine;

[0038] The spray shield 8 is designed below the receiving block 7, and its main function is to prevent the metal chips and coolant generated during the processing from splashing everywhere, thereby ensuring the cleanliness and safety of the processing environment; the coolant and metal chips generated during the engraving process flow into the filter chamber through the water downhole groove 2 on the operating table 1; the filter chamber is used to filter out large particles of metal chips to prevent these metal chips from entering the water storage tank 9 and causing blockage; the filtered coolant flows back to the water storage tank 9 through the flexible pipe, thereby realizing the recycling of the coolant and improving the efficiency of resource utilization; the large particles of metal chips intercepted by the first filter screen 13 fall into the slag box 14; when the metal chips accumulate to a certain extent, the slag box 14 can be opened for cleaning, thereby maintaining the continuous and efficient operation of the machine; and the smaller particles and coolant will continue to flow through the mesh of the first filter screen 13 and be transported to the water storage tank 9.
