Description

Technical Field

[0001] The utility model relates to the technical field of additive manufacturing of titanium alloy structural parts, in particular to an additive manufacturing auxiliary device for titanium alloy structural parts. Background Art

[0002] Additive manufacturing, commonly known as 3D printing, is a technology that generates objects of any shape by stacking materials directly based on computer graphics data. Additive manufacturing refers to a scientific and technological system that directly manufactures parts based on the discrete-stacking principle and driven by the three-dimensional data of parts. It changes the processing mode of production by cutting and assembling raw materials, and realizes production anytime, anywhere and on demand.

[0003] 3D printing is usually achieved by using digital technology material printers. It is often used to make models in the fields of mold manufacturing, industrial design, etc., and later gradually used for the direct manufacturing of some products. There are already parts printed using this technology. This technology is used in jewelry, footwear, industrial design, architecture, aerospace and other fields; currently in the process of titanium alloy additive manufacturing, the titanium alloy workpiece needs to be fixed on the workbench. The traditional fixing method is to clamp the titanium alloy workpiece directly. In this way, when the titanium alloy workpiece is processed, the clamping part is often blocked and cannot be processed, thereby affecting the final processing effect of the titanium alloy workpiece.

[0004] For example, the utility model with application number 202120793348.6 discloses an additive manufacturing auxiliary device for large titanium alloy structural parts. This additive manufacturing auxiliary device for large titanium alloy structural parts is different from the existing technology, has a reasonable structure, is easy to use, and is simple to operate, so that users can understand the working principle simply and clearly; the first clamping seat and the second clamping seat are used to simultaneously clamp and fix the two ends of the titanium alloy workpiece to achieve processing of the middle part of the titanium alloy workpiece. When the clamping frame is clamped and connected to the middle part of the titanium alloy workpiece, the two ends of the titanium alloy workpiece are processed, which avoids the clamping part of the titanium alloy workpiece from being unable to be processed, thereby affecting the final processing effect, thereby improving the convenience of processing the titanium alloy workpiece, and at the same time greatly improves the moving space of the instrument during processing, and improves the practicality of the device.

[0005] Similar to the above application, there are still some shortcomings:

[0006] This type of additive manufacturing auxiliary device for large titanium alloy structural parts improves the convenience of carbon alloy workpieces, but does not collect titanium alloy powder during the additive process of the titanium alloy structural parts. Titanium alloy powder is used in the titanium alloy additive manufacturing process, and the lack of an auxiliary collection structure will cause the titanium alloy powder to accumulate on the workbench, which not only affects the heat dissipation of the titanium alloy structural parts and reduces product quality, but also increases the workload for subsequent cleaning.

[0007] Therefore, an additive manufacturing auxiliary device for titanium alloy structural parts is designed to optimize the above problems. Utility Model Content

[0017] The utility model provides an additive manufacturing auxiliary device for titanium alloy structural parts. Through the coordinated use of a workbench, a hydraulic cylinder, a fixed pipe, an adjusting rod, a movable frame, a supporting plate, a sliding frame and a fixing port, the device can collect excess titanium alloy powder during the additive manufacturing process of titanium alloy structural parts, which not only reduces the heat dissipation effect of the titanium alloy powder on the titanium alloy structural parts, but also reduces the workload of the later staff. The movable frame spacing can be adjusted according to the size of the titanium alloy structural parts, making the device more flexible to use.

[0018] Through the coordinated use of the motor, the screw, the push rod, the brush, the sliding hole, the slider, the cleaning frame and the screw hole, the motor is started to drive the screw to rotate, so that the push rod and the cleaning frame outside the screw move back and forth, and the brush on one side of the push rod performs secondary cleaning of the excess residual powder on the top of the workbench and collects the cleaned powder in the cleaning frame, thereby further facilitating the cleaning work of the staff and meeting the use needs of people;

[0019] Through the coordinated use of the protective shell and the operating door, the setting of the protective shell increases the protective effect of the processing process on the top of the workbench, which not only reduces the powder pollution of the surrounding air, but also reduces the internal noise transmission, thereby improving the practicality of the additive manufacturing auxiliary device of the titanium alloy structural part.
