Description

Technical Field

[0001] The invention relates to the field of 3D printing, and in particular to a leveling device for a 3D printer base. Background Art

[0002] 3D printing is a rapid prototyping technology that has been used more and more widely in recent years, especially in the prototyping of irregular objects.

[0003] Since the shapes and sizes of 3D printed products are inconsistent, there are very few symmetrical objects. This will cause uneven force on the top surface of the printing base, and the printing base may tilt, which will require re-printing, seriously affecting the progress of the printing work. A slight tilt will have a certain impact on the printing quality, and when the printed product is removed from the printing base, some material may remain on its surface. If it is not cleaned in time, it will affect the next printing work. In order to improve the work efficiency and product quality of 3D printing, we proposed a leveling device for the 3D printer base.

A notch is provided on the bottom of the T-shaped round rod, and the second rotating rod is fixedly connected inside the notch.

[0011] Furthermore, the fixed block includes a support plate, a transverse plate, a straight rod and a cylinder.

[0012] The fixed block includes a trapezoidal block, a push plate, a triangular block and a force rod.

[0014] The present invention has the beneficial effects.

[0015] The present invention uses a square frame. After the staff starts the hydraulic press, the square block will move upward under the push of the hydraulic press. The square plate will gradually rise to a height convenient for work under the push of the connecting block and the cross top plate. The arc frame can limit the arc plate fixed on the bottom of the square plate to its inner side, so as to limit the position of the square plate and avoid shaking during 3D printing to affect product quality. At the same time, the problem of the square plate tilting to one side due to gravity is eliminated. Relying on the special shape setting of the cross top plate, since it has a large contact area with the square plate, it can support the gravity exerted on the square plate, thereby greatly increasing the force strength of the square plate.

[0016] The present invention uses the square block, and the support rod will drive the T-shaped round rod to move upward under the traction of the connecting plate. At this time, the four corners of the bottom of the square plate will be simultaneously subjected to the force of the semicircular plate and the fan-shaped plate, thereby respectively supporting the four corners of the bottom of the square plate. At the same time, because the semicircular plate and the fan-shaped plate are stuck in the arc groove, the problem of the square plate tilting is further eliminated. The elastic plate can support the round block due to its own elastic force. However, due to its limited elastic force, when the square plate is placed on the top of the semicircular plate, the elastic plate will be in a state of force compression, thereby achieving the effect of force support. As the support rod gradually rises, the slider will drive the arc rod to move downward along the opening under the influence of gravity. At this time, the force strength of the outer end of the support rod increases, which makes the overall center of gravity move downward, and the support of the square plate will be more stable. Through the inclined rod, when the hydraulic actuator drives the square plate to move to the lowest height, the lower end of the inclined rod will contact the top of the base plate, thereby sharing and supporting the force received by the arc rod.

[0017] The present invention uses a fixed block, and when printing is completed, the staff can directly remove the printed object and the square plate together, and then replace the square plate without the printed object to work again, which reduces the problem of material adhering to the top of the printed object when it is separated from the square plate. After the staff starts the cylinder, the trapezoidal block continues to move forward under the push of the air push rod, and then the lower end of the front side of the push plate will contact the top of the square plate, and the impurities remaining on the top of the square plate will be removed by the push plate. When the push plate encounters more stubborn impurities, the push plate will transmit the reaction force it receives to the spring through the triangular block, and the spring will be in a compressed state after being stressed. When the spring is compressed to a certain extent, the thrust given to the push plate when the spring rebounds can enable the push plate to remove the impurities. Through the force-bearing rod, the role of limiting the position of the push plate is achieved, and the spring can also be disguised as applying most of the force to the push plate located directly in front when expanding, thereby improving the cleaning effect of the residue.

[0018] The present invention uses a trapezoidal block. Due to the special shape setting of the trapezoidal block itself, the residue can be secondary cleaned on the basis of the push plate, thereby avoiding the problem of incomplete cleaning. The vertical rod can increase the connectivity between the air push rod and the trapezoidal block, thereby improving the fixing effect with the trapezoidal block. The multi-concave connecting plate can connect the two air push rods together so that they are on the same horizontal plane, thereby avoiding the problem of the trapezoidal block tilting due to different forces when being pushed. The push plate can be stored inside the fixing block when not in use, so that it will not affect the work of 3D printing. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] Example 1

[0032] See also Figure 1-Figure 6 The present invention is a leveling device for a 3D printer base, comprising:

[0033] A substrate 1, wherein arc grooves are formed at the four corners of the bottom of the substrate 1, a square frame 2 is formed at the top of the substrate 1, and a right-angle groove is formed at the top of the square frame 2, a limiting plate 3 is fixedly connected inside the right-angle groove, and the limiting plate 3 is a right-angle shape, and the inner and outer surfaces of the limiting plate 3 are fixedly connected to the inner wall of the right-angle groove, a square plate 4 is formed directly above the substrate 1, and a fixing block 5 is formed at the upper end of the back of the substrate 1;

[0034] The square frame 2 includes a cross bottom plate 21, a hydraulic press 22, a cylindrical rod 23, a square block 24, a connecting block 25, a cross top plate 26 and an arc frame 27. The cross bottom plate 21 is arranged on the top of the base plate 1, and the cross bottom plate 21 is fixedly connected to the inner surface of the square frame 2. The hydraulic press 22 is fixedly mounted on the top of the cross bottom plate 21. The cylindrical rod 23 is arranged on the outside of the hydraulic press 22, and the bottom of the cylindrical rod 23 is fixedly connected to the top of the cross bottom plate 21. The square block 24 is fixedly connected to the top of the output end of the hydraulic press 22. The connecting block 25 is fixedly mounted on the top of the square block 24, and the shape of the connecting block 25 It is cylindrical, and the cross top plate 26 is fixedly connected to the upper end of the outer surface of the connecting block 25. Relying on the special shape setting of the cross top plate 26, due to the large contact area between itself and the square plate 4, it can support the gravity exerted on the square plate 4, greatly increasing the force strength of the square plate 4. The arc frame 27 is fixedly connected to the outer end of the cross top plate 26. Through the square frame 2, after the staff starts the hydraulic press 22, the square block 24 will move upward under its push, and the square plate 4 will gradually rise to a height convenient for work under the push of the connecting block 25 and the cross top plate 26;

[0035] The bottom of the substrate 1 is in contact with the top of the cross top plate 26, and an arc-shaped plate is fixedly connected to the bottom of the substrate 1, and the outer surface of the arc-shaped plate is in contact with the inner surface of the arc-shaped frame 27. Through the arc-shaped frame 27, the arc-shaped frame 27 can limit the arc-shaped plate fixed at the bottom of the square plate 4 to its inner side, thereby limiting the position of the square plate 4, avoiding shaking during 3D printing that affects the product quality, and at the same time preventing the square plate 4 from tilting to one side due to gravity.

[0036] The outer surface of the square block 24 is fixedly connected with a connecting plate 241, and the upper and lower sides of the square block 24 are fixedly connected with right-angle rods 242, and the right-angle rods 242 are connected to the connecting plate 241. A rotating rod 1 is horizontally arranged on the outer side of the square block 24, and the left and right ends of the rotating rod 1 are fixedly connected to the side of the connecting plate 241. The outer surface of the rotating rod 1 is fixedly connected with a supporting rod 243, and an opening 1 is opened at the central axis of the supporting rod 243. A slider 244 is arranged at the central axis of the opening 1, and the slider 244 is cylindrical in shape. Arc rods 245 are arranged on the left and right sides of the supporting rod 243, and the lower end of the arc rod 245 is fixed. A joint plate 246 is installed, and the arc rod 245 is fixedly connected to the square frame 2 through the joint plate 246. An inclined rod 247 is arranged directly below the support rod 243. Through the square block 24, the support rod 243 drives the T-shaped round rod 312 to move upward under the traction of the connecting plate 241. At this time, the four corners of the bottom of the square plate 4 will be simultaneously subjected to the force of the semicircular plate 32 and the fan-shaped plate 33, thereby supporting the four corners of the bottom of the square plate 4 respectively. At the same time, because the semicircular plate 32 and the fan-shaped plate 33 are stuck in the arc groove, the problem of the square plate 4 tilting is further eliminated;

[0037] The left and right sides of the inclined rod 247 are fixedly connected to the side of the arc rod 245, and the bottom of the inclined rod 247 is in contact with the top of the base plate 1. Through the inclined rod 247, when the hydraulic press 22 drives the square plate 4 to move to the lowest height, the lower end of the inclined rod 247 will contact the top of the base plate 1, thereby sharing and supporting the force exerted on the arc rod 245.

[0038] The slider 244 is cylindrical in shape, and the outer surface of the slider 244 is in contact with the inner wall of the opening. A circular opening is opened at the top of the arc rod 245, and the inner surface of the circular opening is fixedly connected to the outer surface of the slider 244. The bottom of the joint plate 246 is in contact with the top of the base plate 1. As the support rod 243 gradually rises, the slider 244 will drive the arc rod 245 to move downward along the opening under the influence of gravity. At this time, the force strength on the outer end of the support rod 243 increases, causing the overall center of gravity to move downward, which will be more stable for the support of the square plate 4.

[0039] The limiting plate 3 includes a circular block 31, a semicircular plate 32 and a fan-shaped plate 33. The semicircular plate 32 is fixedly connected to the upper end of the outer surface of the circular block 31, and the fan-shaped plate 33 is fixedly connected to the outer surface of the semicircular plate 32. The outer surface of the fan-shaped plate 33 contacts the inner surface of the arc groove.

[0040] The side of the semicircular plate 32 away from the sector plate 33 is fixedly connected to the inner surface of the limiting plate 3, and the top of the semicircular plate 32 is in contact with the top of the inner wall of the arc groove.

[0041] The circular block 31 includes a sliding plate 311, a T-shaped round rod 312, an annular block 313, an elastic plate 314 and a second rotating rod 315. A cylindrical groove is provided on the top of the circular block 31, and the bottom of the sliding plate 311 contacts the bottom of the inner wall of the cylindrical groove. The T-shaped round rod 312 is arranged directly below the circular block 31, and the top of the T-shaped round rod 312 is fixedly connected to the bottom of the sliding plate 311. The annular block 313 is fixedly connected to the outer surface of the lower end of the T-shaped round rod 312. The elastic plate 314 is fixedly connected to the top of the annular block 313, and the top of the elastic plate 314 is connected to the bottom of the circular block 31. A notch is provided at the bottom of the T-shaped round rod 312, and the second rotating rod 315 is fixedly connected to the inside of the notch. Through the elastic plate 314, due to its own elastic force, the circular block 31 can be supported. However, due to its limited elastic force, when the square plate 4 is placed on the top of the semicircular plate 32, the elastic plate 314 will be in a state of force compression, thereby achieving the effect of force support.

[0042] The support rod 243 is fixedly connected to the outer surface of the second rotating rod 315. The sliding plate 311 is circular in shape, and the outer surface of the sliding plate 311 is in contact with the inner wall of the cylindrical groove.

[0043] Example 2

[0044] The distinguishing features from Example 1;

[0045] See also Figure 7-10 The present invention is a leveling device for a 3D printer base, comprising:

[0046] The fixed block 5 includes a support plate 51, a transverse plate 52, a straight rod 53 and a cylinder 54. The support plate 51 is fixedly connected to the bottom of the fixed block 5, the transverse plate 52 is fixedly connected to the bottom of the support plate 51, the transverse plate 52 is fixedly connected to the top of the base plate 1 through the straight rod 53, and the cylinder 54 is arranged on the back of the fixed block 5, and the bottom of the cylinder 54 is fixedly connected to the top of the support plate 51. Through the fixed block 5, when printing is completed, the staff can directly remove the printed object together with the square plate 4, and then replace the square plate 4 without the printed object to work again, which reduces the problem of material adhering to the top of the square plate 4 when the printed object is separated from the square plate 4;

[0047] The front side of the fixing block 5 is provided with an opening 2, the height of the bottom of the inner wall of the opening 2 is the same as the height of the top of the square plate 4, and the push plate 532 can be stored inside the fixing block 5 when not in use, so that it will not affect the work of 3D printing.

[0048] The fixed block 5 includes a trapezoidal block 531, a push plate 532, a triangular block 533 and a force rod 534. The trapezoidal block 531 is slidably connected to the inside of the second opening, and a groove is provided at the central axis of the front side of the trapezoidal block 531. The push plate 532 is arranged on the front side of the trapezoidal block 531. The triangular block 533 and the force rod 534 are both fixedly connected to the back side of the push plate 532.

[0049] The four sides of the push plate 532 are in contact with the inner wall of the opening. After the staff starts the cylinder 54, the trapezoidal block 531 continues to move forward under the push of the air push rod 72, and then the lower end of the front side of the push plate 532 will contact the top of the square plate 4, and the impurities remaining on the top of the square plate 4 will be removed by the push plate 532. When the push plate 532 encounters more stubborn impurities, the push plate 532 will transfer the reaction force it receives to the spring through the triangular block 533. The spring will be compressed after being stressed. When the spring is compressed to a certain extent, the thrust given to the push plate 532 when the spring rebounds can enable the push plate 532 to remove the impurities.

[0050] A spring is fixedly connected to one side of the triangular block 533 away from the push plate 532, and one end of the spring away from the triangular block 533 is fixedly connected to the inner wall of the groove. One end of the force-bearing rod 534 away from the push plate 532 penetrates the trapezoidal block 531 and extends to the inside. Through the force-bearing rod 534, the position of the push plate 532 is limited, and the spring can apply most of the force to the push plate 532 located in the front when expanding, thereby improving the cleaning effect of the residue.

[0051] The upper and lower sides of the force bearing rod 534 are in contact with the inner wall of the groove.

[0052] The cam 74 is provided with a plurality of cams 75, and the cam 75 is provided with a plurality of cams 76. The cam 74 is provided with a plurality of cams 77 and a plurality of cams 78. The cam 74 is provided with a plurality of cams 77 and a plurality of cams 79.

[0053] The connecting frame 71 is connected to the cylinder 54 through the air push rod 72, and the end of the vertical rod 74 away from the platform block is fixedly connected to the trapezoidal block 531. The vertical rod 74 can increase the connectivity between the air push rod 72 and the trapezoidal block 531 and improve the fixing effect with the trapezoidal block 531.

[0054] A specific application of this embodiment is: after the staff starts the hydraulic press 22, the square block 24 will move upward under its push, and the square plate 4 will gradually rise to a height convenient for work under the push of the connecting block 25 and the cross top plate 26. Through the arc frame 27, the arc frame 27 can limit the arc plate fixed at the bottom of the square plate 4 to its inner side, so as to limit the position of the square plate 4, avoid shaking during 3D printing to affect the product quality, and at the same time prevent the square plate 4 from tilting to one side due to gravity. Relying on the special shape setting of the cross top plate 26, due to the large contact area between itself and the square plate 4, it can support the gravity received by the square plate 4, greatly increasing the force strength of the square plate 4;

[0055] The support rod 243 will drive the T-shaped round rod 312 to move upward under the traction of the connecting plate 241. At this time, the four corners of the bottom of the square plate 4 will be simultaneously subjected to the force of the semicircular plate 32 and the fan-shaped plate 33, thereby respectively supporting the four corners of the bottom of the square plate 4. At the same time, because the semicircular plate 32 and the fan-shaped plate 33 are stuck in the arc groove, the problem of the square plate 4 tilting is further eliminated. The elastic plate 314 can support the circular block 31 due to its own elastic force. However, due to its limited elastic force, when the square plate 4 is placed on the top of the semicircular plate 32, the elastic plate 314 will be in a state of force compression, achieving the effect of force support. As the support rod 243 gradually rises, the slider 244 will be affected by gravity and will drive the arc rod 245 to move downward along the opening. At this time, the force strength of the outer end of the support rod 243 increases, causing the overall center of gravity to move downward, and the support for the square plate 4 will be more stable.

[0056] When printing is completed, the staff can directly remove the printed object and the square plate 4 together, and then replace the square plate 4 without the printed object to work again, which reduces the problem of material adhering to the top of the printed object when it is separated from the square plate 4. After the staff starts the cylinder 54, the trapezoidal block 531 continues to move forward under the push of the air push rod 72, and then the lower end of the front side of the push plate 532 will contact the top of the square plate 4, and the impurities remaining on the top of the square plate 4 will be removed by the push plate 532. When the push plate 532 encounters more stubborn impurities, the push plate 532 will transmit the reaction force it receives to the spring through the triangular block 533. The spring will be compressed after being stressed. When the spring is compressed to a certain extent, the thrust given to the push plate 532 when the spring rebounds can enable the push plate 532 to remove the impurities.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention.
