Description

Technical Field

[0001] This utility model relates to the field of 3D printing equipment technology, and in particular to a bidirectional scraper leveling device for 3D printing equipment. Background Technology

[0002] In metal 3D printing technology, the powder spreading method has a significant impact on printing efficiency and material utilization. Traditional unidirectional powder spreading pushes excess powder to the overflow port, requiring manual recovery. This method not only results in low powder utilization but also leads to frequent manual powder replenishment and recovery, severely limiting printing efficiency. With the widespread application of metal 3D printing equipment in various fields, unidirectional powder spreading can no longer meet the growing printing demands. Bidirectional powder spreading technology has emerged, capable of spreading excess powder in the opposite direction for printing, significantly improving powder utilization and printing efficiency. However, bidirectional powder spreading technology places extremely stringent requirements on the flatness and parallelism of the squeegee. Ordinary squeegee leveling methods are insufficient to achieve the required precision. Therefore, solving the squeegee leveling challenge in bidirectional powder spreading has become crucial for the further development of metal 3D printing technology. Summary of the Invention

[0003] The purpose of this invention is to provide a bidirectional scraper leveling device for 3D printing equipment, which improves the leveling accuracy of the bidirectional scraper in 3D printing equipment.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A bidirectional scraper leveling device for 3D printing equipment, comprising:

[0006] scraper;

[0007] A scraper fixing assembly for accommodating and fixing the scraper;

[0008] A jig processing assembly, wherein the scraper fixing assembly is detachably connected to the jig processing assembly, and the jig processing assembly is used to perform a leveling operation on the scraper fixed in the scraper fixing assembly.

[0009] Optionally, the scraper fixing assembly includes a scraper fixing clip and a scraper mounting base. The scraper fixing clip is detachably connected to the upper surface of the scraper mounting base, and the scraper fixing clip has a pressure plate for locking the scraper.

[0010] Optionally, the scraper fixing clip is further provided with a pin hole, which is used to connect to the fixture processing assembly via a pin, so that the fixture processing assembly can level the scraper.

[0011] Optionally, the scraper fixing assembly further includes a scraper bracket for mounting the scraper fixing clip and the scraper mounting base.

[0012] Optionally, the fixture processing assembly includes a fixture base plate, a slide rail structure, a dial indicator, and a leveling screw.

The leveling screw is used to adjust the height of the scraper fixing clip.

[0013] Optionally, the jig processing assembly further includes an adjusting plate connected to the adjusting set screw, and the adjusting plate is configured to drive the scraper fixing clip to move in the height direction to adjust the height of the scraper.

[0014] Optionally, the number of scrapers is set to two, and the two scrapers are arranged in parallel on the scraper fixing clamp.

[0015] Compared with existing technologies, the bidirectional scraper leveling device for 3D printing equipment provided by this utility model effectively improves powder utilization.

[0027] Please see Figures 1-3 The 3D printing equipment bidirectional scraper leveling device 100 provided in this embodiment includes a scraper 1, a scraper fixing component 2, and a fixture processing component 3. The scraper fixing component 2 is used to accommodate and fix the scraper 1. The scraper fixing component 2 is detachably connected to the fixture processing component 3, and the fixture processing component 3 is used to perform leveling operation on the scraper 1 fixed in the scraper fixing component 2.

[0028] In this application, the scraper fixing assembly 2 includes a scraper fixing clip 21 and a scraper mounting base 22. The scraper fixing clip 21 is detachably connected to the upper surface of the scraper mounting base 22. The scraper fixing clip 21 has a pressure plate for locking the scraper 1.

[0029] In one embodiment provided in this application, the scraper fixing clip 21 is further provided with a pin hole, which is used to connect with the fixture processing assembly 3 through a pin, so that the fixture processing assembly 3 can level the scraper 1.

[0030] In this application, the scraper fixing assembly 2 also includes a scraper bracket 23, which is used to install the scraper fixing clip 21 and the scraper mounting base 22.

[0031] In one embodiment provided in this application, the jig processing assembly 3 includes a jig base plate 31, a slide rail structure 32, a dial indicator 33, and a leveling screw 34. The jig base plate 31 is used to connect and fix with the scraper mounting seat 22. The slide rail structure 32 is disposed on the jig base plate 31. The dial indicator 33 is connected to the slide rail structure 32 and can move along the length direction of the slide rail structure 32. The leveling screw is used to adjust the height of the scraper fixing clip 21.

[0032] In this application, the jig processing assembly 3 also includes an adjustment plate 35, which is connected to an adjustment set screw and is configured to drive the scraper fixing clip 21 to move in the height direction to adjust the height of the scraper 1.

[0033] Specifically, the number of scrapers 1 is set to two, and the two scrapers 1 are arranged in parallel on the scraper fixing clip 21.

[0034] In practice: Before printing begins, the two scraper clamps 21 are pre-tightened and installed onto the scraper mounting base 22, and then the two are placed as a whole into the leveling fixture. At this time, the fixture base plate 31 is firmly fixed to the scraper mounting base 22 with screws to prevent it from moving. The adjusting plate 35 is inserted into the pin hole of the scraper clamp 21 using pins to facilitate subsequent adjustment by the leveling screw 34. After fixing, the Z-axis lead screw support moves the two dial indicators 33 to the reference surface of the leveling fixture via the slider for calibration and zeroing to ensure the accuracy of the dial indicator 33 measurement data. After calibration, the dial indicator 33 is pressed down onto the plane of the two scrapers 1 to start testing the relative plane dimensions and parallelism of the two scrapers 1. By observing the values ​​displayed by the dial indicator 33, the operator uses the leveling screw 34 to raise and lower the adjusting plate 35 to adjust the relative plane dimensions and parallelism of the two scrapers 1. Once the required precision is achieved, the scraper clamp 21 is locked to the scraper mounting base 22 using the fixing screws to ensure the stability of the scraper 1 during use. Finally, the scraper mounting base 22 is removed from the leveling fixture, placed into the groove of the scraper bracket 23, and locked in place to complete the installation and debugging of the entire leveling device. At this point, the leveled scraper 1 can be used in the bidirectional powder spreading work of the metal 3D printing equipment.

[0035] As can be seen from the structure and specific implementation process of the bidirectional scraper leveling device 100 in the 3D printing equipment, it effectively improves the powder utilization rate. Through the bidirectional powder spreading function, excess powder is reused, which greatly improves the powder utilization rate, reduces material waste, and lowers production costs compared to the traditional unidirectional powder spreading method. It can improve printing efficiency, reduce the frequency of manual powder addition and powder recycling, and enable the equipment to carry out printing work more continuously, significantly improving the overall printing efficiency and meeting the ever-increasing printing demand. Moreover, by using the precise measurement of the dial indicator 33 and the fine adjustment of the leveling top screw 34, the flatness and parallelism of the scraper 1 can be accurately adjusted to meet the high precision requirements of the scraper 1 for bidirectional powder spreading, ensuring the quality and stability of 3D printing.

[0036] In the description of the above embodiments, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.
