Description

Technical Field

[0001] This utility model relates to the field of laser additive manufacturing technology, specifically to a laser additive manufacturing material testing device. Background Technology

[0002] Laser additive manufacturing, commonly known as 3D printing, is a manufacturing technology that integrates computer-aided design, material processing and forming technology. Based on digital model files, it uses software and CNC systems to deposit specialized metal materials, non-metal materials and medical biomaterials layer by layer through methods such as extrusion, sintering, melting, photopolymerization, and spraying to create physical objects.

[0003] A search revealed a Chinese patent document disclosing a laser additive manufacturing material testing device for molds [Announcement No.: CN221594651U]. This device includes a testing platform with a conveyor belt on one side, a pushing mechanism on the platform surface, a grinding assembly on the other side, a cleaning mechanism on the platform surface, a weighing platform, and four evenly distributed support frames at the bottom. This invention, through its cleaning mechanism, facilitates the cleaning and collection of debris, effectively suppressing debris dispersion and improving cleanliness during operation.

[0004] After processing, laser additive manufacturing materials need to undergo wear resistance testing. This is usually done by grinding the material and then taking an average value through multiple weighings to obtain accurate data. The above solution simply clamps the material and grinds it from the top. Considering the varying heights of the material, if the clamping position is not precisely at the top of the material, the material may shift during grinding, making effective grinding impossible and affecting the accuracy of subsequent testing. Utility Model Content

[0005] The purpose of this invention is to provide a laser additive manufacturing material testing device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a laser additive manufacturing material testing device, comprising a testing platform, a weighing platform fixedly installed on the top of the testing platform, a horizontal plate provided on the top of the testing platform, two first hydraulic rods fixedly installed on the top of the testing platform, the output ends of the first hydraulic rods fixedly connected to the bottom of the horizontal plate, a grinding motor fixedly installed on the bottom of the horizontal plate, a grinding head fixedly connected to the output end of the grinding motor, a rotating platform fixedly installed on the top of the testing platform opposite to the position of the grinding head, two clamping plates symmetrically arranged on the top of the rotating platform, and two side plates slidably connected to one side of the two clamping plates; A clamping mechanism is fixedly mounted on one side of a clamping plate and can control the clamping plate to clamp the manufacturing material. An adjustment mechanism is fixedly mounted on the side plate and can adjust the position of the side plate.

[0007] Preferably, the clamping mechanism includes a sleeve disposed on one side of the clamping plate, the bottom of the sleeve being fixedly connected to the top of the rotating platform, a second hydraulic rod being fixedly installed on the inner wall of the sleeve, a support block being fixedly installed at the output end of the second hydraulic rod, a third hydraulic rod being fixedly installed on one side of the support block, one end of the third hydraulic rod penetrating to one side of the support block and being fixedly connected to one side of the clamping plate.

[0008] Preferably, the adjustment mechanism includes a dovetail block fixedly connected to one side of the side plate, an L-shaped bracket fixedly connected to the top of the dovetail block, a housing fixedly connected to the top of the L-shaped bracket, a movable block disposed inside the housing, a positioning rod fixedly connected to the bottom of the movable block, the bottom of the positioning rod penetrating to the bottom of the housing, a positioning hole for cooperating with the positioning rod being opened on the top of the clamping plate, a traction rod fixedly connected to the top of the movable block, the top of the traction rod penetrating to the top of the housing, and a traction block fixedly connected thereto.

[0009] Preferably, a spring is fitted onto the surface of the traction rod, the top of the spring is fixedly connected to the inner wall of the housing, and the bottom of the spring is fixedly connected to the top of the moving block.

[0010] Preferably, the number of positioning holes is several, and they are evenly distributed on the top of the clamping plate.

[0011] Preferably, a dovetail groove is provided on one side of the clamping plate, and the dovetail groove is used in conjunction with the dovetail block.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. By setting up a clamping mechanism, this utility model enables the support block and clamping plate to move upward after the manufacturing material is moved onto the rotating table by activating the second hydraulic rod, so that the height of the clamping plate is just at the upper part of the manufacturing material. Then, the third hydraulic rod is activated, which pushes the clamping plate closer to the manufacturing material. The manufacturing material is fixed by the two clamping plates, and the two side plates are just located on the other two sides of the manufacturing material. This can effectively improve the stability of the manufacturing material during the subsequent grinding process, prevent positional displacement, and thus improve the accuracy of subsequent testing. 2. This utility model, by setting an adjustment mechanism, can adjust the position of the side plate when it does not match the width of the manufacturing material. By pulling the traction block upward, the traction block will drive the traction rod, the moving block, and the positioning rod upward, causing the positioning rod to leave the positioning hole. Then, the position of the dovetail block and the side plate can be adjusted along the trajectory of the dovetail groove. After reaching the appropriate position, the traction block is released, and the elastic force generated by the spring will push the moving block and the positioning rod downward, causing the positioning rod to enter the corresponding positioning hole, thus completing the adjustment of the side plate position. Afterward, the clamping mechanism controls the clamping plate to clamp the manufacturing material, and the side plate will be located on the other two sides of the manufacturing material, improving the stability of the manufacturing material during the grinding process.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1 - Figure 5 As shown, Example 1: A laser additive manufacturing material testing device includes a testing platform 1, a weighing platform 2 fixedly installed on the top of the testing platform 1, a horizontal plate 3 set on the top of the testing platform 1, two first hydraulic rods 4 fixedly installed on the top of the testing platform 1, the output ends of the first hydraulic rods 4 fixedly connected to the bottom of the horizontal plate 3, a grinding motor 5 fixedly installed on the bottom of the horizontal plate 3, a grinding head 6 fixedly connected to the output end of the grinding motor 5, a rotating platform 7 fixedly installed on the top of the testing platform 1 opposite to the position of the grinding head 6, two clamping plates 8 symmetrically arranged on the top of the rotating platform 7, and two side plates 9 slidably connected to one side of the two clamping plates 8. A clamping mechanism is fixedly installed on one side of the clamping plate 8, which can control the clamping plate 8 to clamp the manufacturing material; An adjustment mechanism is fixedly mounted on the side plate 9, which can adjust the position of the side plate 9.

[0017] The clamping mechanism includes a sleeve 10 disposed on one side of the clamping plate 8. The bottom of the sleeve 10 is fixedly connected to the top of the rotating table 7. A second hydraulic rod 11 is fixedly installed on the inner wall of the sleeve 10. A support block 12 is fixedly installed at the output end of the second hydraulic rod 11. A third hydraulic rod 13 is fixedly installed on one side of the support block 12. One end of the third hydraulic rod 13 extends through to one side of the support block 12 and is fixedly connected to one side of the clamping plate 8.

[0018] In this embodiment, the height of the manufacturing materials varies. If the clamping position is not exactly located at the upper part of the manufacturing material, the manufacturing material is prone to positional displacement during the grinding process, resulting in ineffective grinding and affecting the accuracy of subsequent inspections. Therefore, by setting up a clamping mechanism, after the manufacturing material is moved onto the rotating table 7, the second hydraulic rod 11 can be activated to push the support block 12 and clamping plate 8 and other structures upward, so that the height of the clamping plate 8 is exactly located at the upper part of the manufacturing material. Then, the third hydraulic rod 13 is activated, which pushes the clamping plate 8 closer to the manufacturing material. The manufacturing material is fixed by the two clamping plates 8, and the two side plates 9 are located on the other two sides of the manufacturing material. This can effectively improve the stability of the manufacturing material during the subsequent grinding process, prevent positional displacement, and thus improve the accuracy of subsequent inspections.

[0019] Example 2: Based on Embodiment 1, this embodiment improves the stability of the manufacturing material during the grinding process by clamping the top position of the manufacturing material with two clamping plates 8 and positioning the side plates 9 on the other two sides of the manufacturing material. However, considering that the width of the manufacturing material varies, if the side plates 9 cannot be adjusted, it will also affect the stability of the manufacturing material during grinding. In this application, the adjustment mechanism includes a dovetail block 14 fixedly connected to one side of the side plate 9. An L-shaped bracket 15 is fixedly connected to the top of the dovetail block 14. A housing 16 is fixedly connected to the top of the L-shaped bracket 15. A moving block 17 is provided inside the housing 16. A positioning rod 18 is fixedly connected to the bottom of the moving block 17. The bottom of the positioning rod 18 extends through to the bottom of the housing 16. A positioning hole 19 is provided on the top of the clamping plate 8 to cooperate with the positioning rod 18. A traction rod 20 is fixedly connected to the top of the moving block 17. The top of the traction rod 20 extends through to the top of the housing 16 and is fixedly connected to a traction block 21.

[0020] In this embodiment, by setting an adjustment mechanism, when the position of the side plate 9 does not match the width of the manufacturing material, the traction block 21 can be pulled upward. The traction block 21 will drive the traction rod 20, the moving block 17 and the positioning rod 18 to move upward, so that the positioning rod 18 leaves the interior of the positioning hole 19. Then, the position of the dovetail block 14 and the side plate 9 can be adjusted along the trajectory of the dovetail groove 23. After reaching the appropriate position, the traction block 21 is released, and the elastic force generated by the spring 22 will push the moving block 17 and the positioning rod 18 downward, so that the positioning rod 18 enters the interior of the corresponding positioning hole 19, completing the adjustment of the position of the side plate 9. Afterward, after the clamping mechanism controls the clamping plate 8 to clamp the manufacturing material, the side plate 9 will be located on the other two sides of the manufacturing material, improving the stability of the manufacturing material during the grinding process.

[0021] A spring 22 is fitted onto the surface of the traction rod 20. The top of the spring 22 is fixedly connected to the inner wall of the housing 16, and the bottom of the spring 22 is fixedly connected to the top of the moving block 17.

[0022] In this embodiment, by setting a spring 22, when the traction block 21 is released, the elastic force generated by the spring 22 will push the moving block 17 and the positioning rod 18 downward, so that the positioning rod 18 enters the corresponding positioning hole 19, which plays a role in resetting.

[0023] The number of positioning holes 19 is several, and they are evenly distributed on the top of the clamping plate 8.

[0024] In this embodiment, by setting the positioning hole 19, the positioning rod 18 can be quickly fixed by entering the corresponding positioning hole 19 after the position of the side plate 9 is adjusted.

[0025] A dovetail groove 23 is provided on one side of the clamping plate 8, and the dovetail groove 23 is used in conjunction with the dovetail block 14.

[0026] In this embodiment, by setting the dovetail groove 23, the movement trajectory of the side plate 9 can be restricted through the cooperation between the dovetail block 14 and the dovetail groove 23, so that it can only be adjusted along the dovetail groove 23, thereby improving the stability of the side plate 9.

[0027] Working principle: After the manufacturing material is moved onto the rotating table 7, the second hydraulic rod 11 can be activated to push the support block 12 and clamping plate 8 and other structures upward, so that the height of the clamping plate 8 is just at the upper part of the manufacturing material. Then, the third hydraulic rod 13 is activated, which will push the clamping plate 8 closer to the manufacturing material. The manufacturing material is fixed by the two clamping plates 8. At the same time, the two side plates 9 are just located on the other two sides of the manufacturing material, which can effectively improve the stability of the manufacturing material in the subsequent grinding process, and prevent positional displacement, thereby improving the accuracy of subsequent inspection. When the position of the side plate 9 does not match the width of the manufacturing material, the traction block 21 can be pulled upwards. The traction block 21 will drive the traction rod 20, the moving block 17 and the positioning rod 18 to move upwards, so that the positioning rod 18 leaves the interior of the positioning hole 19. Then, the position of the dovetail block 14 and the side plate 9 can be adjusted along the trajectory of the dovetail groove 23. After reaching the appropriate position, the traction block 21 is released. The elastic force generated by the spring 22 will push the moving block 17 and the positioning rod 18 downwards, so that the positioning rod 18 enters the interior of the corresponding positioning hole 19, thus completing the adjustment of the position of the side plate 9. Afterwards, the clamping mechanism controls the clamping plate 8 to clamp the manufacturing material, and the side plate 9 will be positioned on the other two sides of the manufacturing material, improving the stability of the manufacturing material during the grinding process.
