Description

Technical Field

[0001] This utility model relates to the field of 3D printing equipment, and in particular to a 3D printing equipment suitable for large structural parts. Background Technology

[0002] In the field of large-scale structural 3D printing, the operational stability and printing accuracy of the equipment directly determine the product quality. Currently, the track lubrication system of traditional 3D printing equipment generally adopts the method of directly applying lubricating oil, which has revealed many problems in long-term use.

[0003] During the printing of large structural components, the equipment needs to run continuously for extended periods. Due to their large size and long length, the friction between the electric track and the sliding block generates metal shavings. Additionally, dust and processing residues from the manufacturing environment easily adhere to the track surface. When lubricating oil is applied directly, these impurities mix with the oil to form oil sludge, resulting in uneven lubrication distribution. This not only reduces lubrication effectiveness but also accelerates wear on the track and sliding block due to the "abrasive effect" of the impurities.

[0004] Therefore, it is necessary to propose a 3D printing device suitable for large structural components to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a 3D printing device suitable for large structural parts, in order to solve the problem that when applying lubricating oil in traditional equipment, these impurities will mix with the oil to form oil stains, resulting in uneven distribution of the lubricating layer. This not only reduces the lubrication effect, but also accelerates the wear of the track and sliding block due to the "abrasive effect" of the impurities.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a 3D printing device suitable for large structural parts, including a processing table and uprights fixed on both sides of the top of the processing table, an electric track fixed between the two uprights, a sliding block slidably installed on the electric track, a laser print head at the bottom of the sliding block, and an oil spraying mechanism and a cleaning mechanism respectively inserted into both ends of the sliding block, the oil spraying mechanism and the cleaning mechanism slidingly engaging with the outer side of the electric track;

[0007] The oil spraying mechanism includes a fixed frame, and grooves are provided at the top, bottom and sides of the fixed frame. A nozzle is fixed inside the grooves. An oil delivery mechanism is fixed on one side of the fixed frame and is connected to the nozzle.

[0008] The cleaning mechanism includes a first auxiliary frame, and a cleaning brush is fixed inside the first auxiliary frame.

[0009] Preferably, the oil delivery mechanism includes an oil storage tank, which is fixed to the side of a fixed frame. A pump body is fixed to the bottom of the fixed frame, and the pump body is connected to the oil storage tank and the nozzle respectively through connecting pipes.

[0010] Preferably, a second auxiliary frame is fixed to the side of the fixed frame away from the sliding block, and a sponge is fixed inside the second auxiliary frame. Both the first auxiliary frame and the second auxiliary frame are U-shaped.

[0011] Preferably, slots are provided at both ends of the sliding block, and plugs are fixedly connected to the opposite sides of the second auxiliary frame and the fixed frame, and the plugs are inserted into the corresponding slots;

[0012] A clamping screw is fixed to the top of the sliding block, and one end of the clamping screw is pressed against the surface of the corresponding insert block.

[0013] Preferably, the top of the processing table is used to place large workpieces to be processed.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] 1. This application first thoroughly removes impurities with a cleaning brush, then evenly sprays oil through multi-directional nozzles, and finally applies a second coat with a sponge, which can form a continuous oil film of uniform thickness on the track surface, making the lubrication effect more stable.

[0016] 2. The process involves first cleaning with a cleaning mechanism, then spraying lubricating oil using an oil spraying mechanism, and finally applying the sprayed lubricating oil with a sponge. This prevents impurities from participating in friction at the source. Combined with the buffering effect of a uniform oil film, precise spraying (the oil volume can be adjusted via the pump) and the even diffusion by the sponge improves the utilization rate of the lubricating oil. Simultaneously, it reduces component failures caused by impurities clogging the system. Furthermore, the closed structure of the U-shaped auxiliary frame, along with the second auxiliary frame and the built-in sponge, blocks one side of the fixed frame, preventing oil sprayed from the nozzle from flowing out from the side. Excess oil automatically falls into the groove for collection. This effectively prevents oil splashing and avoids surface contamination of the processed parts. Attached Figure Description

[0022] This utility model provides, for example Figures 1-4 The 3D printing equipment shown is suitable for large structural parts, including a processing table 1 and two uprights 2 fixed to the top of the processing table 1. An electric track 3 is fixed between the two uprights 2. A sliding block 4 is slidably installed on the electric track 3. A laser print head 7 is located at the bottom of the sliding block 4. A spraying mechanism 5 and a cleaning mechanism are respectively inserted into both ends of the sliding block 4. The spraying mechanism 5 and the cleaning mechanism slide in cooperation with the outside of the electric track 3. The spraying mechanism 5 and the cleaning mechanism can move synchronously with the sliding block 4 to ensure timely processing of the processing area during the printing process.

[0023] The top of the processing table 1 is used to place large workpieces to be processed. Its table surface is made of high-strength alloy material and has undergone precision grinding to ensure sufficient flatness and load-bearing capacity, enabling it to stably support large structural parts with significant weight. The spraying mechanism 5 includes a fixed frame 8. Grooves 14 are provided on the top, bottom, and sides of the fixed frame 8. A nozzle 15 is fixed inside the groove 14. An oil delivery mechanism is fixed on one side of the fixed frame 8, and the oil delivery mechanism is connected to the nozzle 15. After the equipment is started, the operator places the large workpiece to be processed on the processing table 1 and sets the printing parameters through the control system. The electric track 3 drives the sliding block 4 to move along the preset trajectory. The laser print head 7 at the bottom of the sliding block 4 starts synchronously, printing the workpiece layer by layer according to the three-dimensional model data.

[0024] The cleaning mechanism includes a first auxiliary frame 6, and a cleaning brush 18 is fixed inside the first auxiliary frame 6. The cleaning brush 18 is made of wear-resistant nylon material, and its bristle density and hardness are optimized so that it can effectively remove dust and impurities from the printing area without damaging the printed surface.

[0025] When the electric track 3 is connected to the power supply, the sliding block 4 slides along the length of the electric track 3. At this time, the cleaning mechanism on one side of the sliding block 4 first processes the area to be printed. The cleaning brush 18 inside the first auxiliary frame 6 contacts the electric track 3 to remove dust, debris and other impurities in the area. As the sliding block 4 moves, the oil spraying mechanism 5 promptly processes the area that has just been cleaned. The pump body 11 in the oil supply mechanism delivers the protective oil or adhesive in the oil tank 12 to the nozzle 15 in the fixed frame 8 through the connecting pipe 13. The multi-directional nozzles 15 distributed at the top, bottom and sides of the fixed frame 8 evenly spray the lubricating oil onto the surface of the electric track 3. After the oil spraying is completed, the second auxiliary frame 9 drives the sponge 10 to evenly apply the sprayed oil onto the electric track 3, which facilitates the subsequent reciprocating movement of the sliding block 4.

[0026] The oil delivery mechanism includes an oil storage tank 12, which is fixed to the side of a fixed frame 8. A pump body 11 is fixed to the bottom of the fixed frame 8. The pump body 11 is connected to the oil storage tank 12 and the nozzle 15 via connecting pipes 13. A flow control valve can be installed on the connecting pipe 13 between the pump body 11 and the nozzle 15 to precisely control the discharge of oil.

[0027] Meanwhile, the second auxiliary frame 9 and the built-in sponge 10 can block one side of the fixed frame 8, preventing the oil sprayed from the nozzle 15 from flowing out from the side. Excess oil will automatically fall into the groove 14, completing the collection task.

[0028] A second auxiliary frame 9 is fixed to the side of the fixed frame 8 away from the sliding block 4. A sponge 10 is fixed inside the second auxiliary frame 9. Both the first auxiliary frame 6 and the second auxiliary frame 9 are U-shaped.

[0029] Slots are provided at both ends of the sliding block 4. Insert blocks 16 are fixedly connected to the opposite side of the second auxiliary frame 9 and the fixed frame 8. Insert blocks 16 are inserted into the corresponding slots.

[0030] A clamping screw 17 is fixed at the top of the sliding block 4. One end of the clamping screw 17 is pressed against the surface of the corresponding insert block 16. The second auxiliary frame 9 and the fixed frame 8 can be inserted into the sliding block 4 through the insert block 16, which facilitates installation and subsequent disassembly. The insert block 16 can be locked by the clamping screw 17.
