Abstract

The present invention discloses a 3D printed turbocharger impeller support rib cutting device, which relates to the technical field of cutting equipment and comprises a slot frame, wherein a cutting auxiliary mechanism is arranged on the top of the slot frame; the cutting auxiliary mechanism comprises a cutting and grinding positioning unit, wherein the cutting and grinding positioning unit is arranged on the top of the slot frame, and the cutting and grinding positioning unit is used to assist in cutting the printed impeller. This 3D printed turbocharger impeller support rib cutting device, by arranging the cutting and grinding positioning unit, enables the user to cut only a part of the support ribs when cutting the support ribs at the bottom of the impeller by controlling the distance of the cutting blade, and can avoid the situation that when the cutting blade directly cuts the connection between the support ribs and the impeller surface, the temperature between the cutting blade and the plastic material may increase due to the high-speed rotation cutting, thereby possibly damaging the printed impeller surface and destroying the original structure. At the same time, the temperature increase may also cause the surface of the plastic part to turn black.

Description

Technical Field

[0001] The present invention relates to the technical field of cutting equipment, and in particular to a 3D printed turbocharger impeller support rib cutting device. Background Art

[0002] The turbocharger impeller is one of the core components in the turbocharging system. It is mainly responsible for improving the power and efficiency of the engine by compressing the intake air. The turbocharger impeller is usually composed of multiple ultra-thin blades. These blades are arranged radially and have complex shapes to meet the aerodynamic requirements during high-speed rotation. The impeller printed by 3D printing technology has support ribs on its surface, which are used to support the printed impeller parts.

[0003] However, when using a cutting device to saw the support ribs on the impeller surface, the existing cutting generally uses a cutting blade to directly cut them off. Although this method is fast, when the cutting blade directly cuts the connection between the support rib and the impeller surface, the temperature between the cutting blade and the plastic material may rise due to the high-speed rotation of the cutting blade, which may damage the printed impeller surface and destroy the original structure. At the same time, the temperature increase may also cause the surface of the plastic part to turn black, and it cannot be ground and polished after cutting. To this end, we propose a 3D printed turbocharger impeller support rib cutting device. Summary of the invention

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The present invention provides a cutting and grinding positioning unit, which allows the user to control the distance of the cutting blade when cutting the support ribs at the bottom of the impeller and only cut off a part of the support ribs. This can prevent the cutting blade from directly cutting the connection between the support ribs and the impeller surface, which may cause the temperature between the cutting blade and the plastic material to rise due to the high-speed rotation of the cutting blade, thereby damaging the printed impeller surface and destroying the original structure. At the same time, the temperature increase may also cause the surface of the plastic part to turn black, and the remaining part of the support ribs can be ground off by grinding. Grinding can fit the surface of the processed object well, and for 3D printed objects, damage to the details can be avoided. At the same time, polishing can further remove scratches that may be generated during cutting and grinding, making the impeller surface smoother and the overall shape more beautiful. In addition, the grinding and polishing positions can be positioned at the beginning, and can be applicable to the grinding and polishing of impeller support ribs of different heights. The scope of application is wider, and the user does not need to manually clamp the support ribs, which is more convenient and efficient.

[0020] The present invention sets a transmission unit and allows the clamped impeller to rotate on the inner wall of the trough frame. The impeller can rotate itself while the inner wall of the trough frame revolves. When it rotates into the cutting area, it can cooperate with the cutting blade to better cut the surface support ribs. It is also suitable for grinding and polishing, so that the grinding and polishing are more uniform.

[0021] The present invention provides a clamping mechanism to facilitate users to better tension and clamp the 3D printed impeller. By tightening and clamping the inner wall of the impeller hole, it can meet the tightening and clamping requirements of impellers of most sizes and models, and will not be affected by the different shapes of the impeller outer surface, thereby increasing the clamping applicability of impellers of different shapes and sizes.

A fixing plate 2113 is provided on the top of the top plate 2101. One end of the first connecting rod 2109 and one end of the second connecting rod 2110 penetrate to the top of the fixing plate 2113. One end of the first connecting rod 2109 and one end of the second connecting rod 2110 are rotatably connected to the inner wall of the fixing plate 2113 through a bearing. One end of the first connecting rod 2109 is fixedly connected to a first sprocket 2114. One end of the second connecting rod 2110 is fixedly connected to a second sprocket 2115.

[0040] The specific implementation of this embodiment is as follows: the user places the trough frame 1 in a suitable position, and after the user clamps and fixes the printed impeller, the user holds the handle 5 to rotate the rotating plate 4, thereby driving the first threaded rod 2119 to rotate. The rotation of the first threaded rod 2119 can enable the connecting plate 2117 threadedly connected on its surface to move downward, and at the same time drive the pressure rod 2118 downward to drive the detection block 2120 to move downward, and the connecting plate 2117 drives the fixing plate 2113 and the first connecting rod 2109 and the second connecting rod 2110 to move downward, thereby driving the sponge sand block 2111 and the polishing wheel 2112 to move downward at the same time.
