Description

Technical Field

[0001] This utility model relates to the field of 3D printing technology, and more specifically, to a blade flatness detection device. Background Technology

[0002] During operation, the blades of a photopolymer 3D printer experience wear and tear on their cutting edges after prolonged exposure to slurry corrosion and mechanical abrasion, leading to a decline in their critical functions. This manifests as: decreased sizing smoothness, resulting in noticeable layer lines on the printed sample; or increased blade roughness causing excessive interference with the cured layer during sizing, potentially inducing layer peeling or displacement, ultimately compromising the quality and geometric consistency of the manufactured part. Therefore, it is necessary to perform flatness testing on the blades after a period of use.

[0003] With the continuous progress of society, the requirements for photopolymer 3D printers are also getting higher and higher. Therefore, before the photopolymer 3D printer is delivered to the user, the blade needs to be tested. This test needs to simulate the temperature and humidity in the user's actual processing environment and then test the flatness of the blade. The blade processing can be adjusted according to the test results. Therefore, there is an urgent need for a testing device that can complete this test. Utility Model Content

[0021] In this utility model, "first" and "second" do not represent a specific quantity or order, but are merely used to distinguish names.

[0022] like Figure 1 , Figure 2 and Figure 3As shown, a blade flatness testing device according to one embodiment of the present invention includes a testing chamber 1, a testing table 2, a positioning seat 3, a limiting component 4, a hot air generator 5, a water mist generator 6, and a flatness testing instrument 7. The testing chamber 1 is provided with a testing door 11. The testing table 2 is horizontally installed inside the testing chamber 1, and the height of the testing table 2 is lower than the height of the testing door 11. The positioning seat 3 is horizontally fixedly installed on the testing table 2. The side of the positioning seat 3 near the testing door 11 has a locking groove 31 for the blade to be inserted. The limiting component 4 is used to restrict the blade within the locking groove 31. The hot air generator 5... Both the generator 5 and the water mist generator 6 are fixedly installed on the testing table 2; the flatness tester 7 is a pointer-type dial indicator with the testing end of the pointer-type dial indicator facing vertically downwards. The flatness tester 7 is slidably installed on the testing table 2 along the length direction of the positioning seat 3, and the testing end of the flatness tester 7 is located directly above the positioning slot 31; thus, after the blade is positioned on the positioning seat 3, the temperature and humidity of the user's processing environment are simulated in the testing chamber 1. After a period of time, the flatness of the blade at various positions along the length direction of the cutting edge is tested by the flatness tester 7, resulting in high testing efficiency.

[0023] Specifically, such as Figure 2 , Figure 3 and Figure 4 As shown, the limiting component 4 includes several clamping blocks 41 and a first driving member 42. The clamping blocks 41 are rubber blocks, and the several clamping blocks 41 are spaced apart along the length direction of the positioning seat 3. The clamping blocks 41 are located on the side of the positioning seat 3 where the locking groove 31 is opened. The first driving member 42 is used to drive each clamping block 41 to move towards or away from the positioning seat 3. The first driving member 42 is a cylinder, and the first driving member 42 is fixedly installed on the detection table 2. The piston rod of the first driving member 42 is fixedly installed on the clamping block 41. Thus, when the blade is placed in the locking groove 31, the first driving member 42 is activated to drive the clamping block 41 to move towards the blade, stabilizing the blade in the locking groove 31.

[0024] Furthermore, the inclined setting of the locking groove 31, with the side of the clamping block 41 near the positioning seat 3 being parallel to the locking groove 31, allows for the positioning of blades with inclined cutting edges, ensuring that the cutting edge plane is in a horizontal state, which facilitates flatness detection.

[0025] The bottom of the slot 31 is provided with a locking rod 32 for locking into a through hole pre-set on the blade, so that the blade can be locked into the slot 31 and play a role in initial positioning.

[0026] Furthermore, each end of the positioning seat 3 is provided with a pressing block 43, which is located directly above the positioning seat 3. The detection table 2 is equipped with a second driving member 44 for driving the pressing block 43 to move closer to or away from the positioning seat 3. The second driving member 44 is a cylinder, which is fixedly installed on the detection table 2. The piston rod of the second driving member 44 is fixedly installed on the pressing block 43. Thus, when the blade is placed in the positioning groove 31, the second driving member 44 is activated to drive the pressing block 43 to move towards the blade, which, together with the clamping block 41, makes the blade more stably positioned in the positioning groove 31.

[0027] Specifically, such as Figure 1 and Figure 2 As shown, the blade flatness detection device also includes a controller and two buttons (not shown in the figure). The hot air generator 5 and the water mist generator 6 are both electrically connected to the controller, and the controller is electrically connected to the buttons. The two buttons are used to control the opening and closing of the hot air generator 5 and the water mist generator 6, respectively. A temperature display 12 and a humidity display 13 are fixedly installed on the outer wall of the detection chamber 1. A temperature sensor and a humidity sensor are fixedly installed inside the detection chamber 1. The temperature sensor and the humidity sensor are used to detect the temperature and humidity inside the detection chamber 1, respectively. Both the temperature sensor and the humidity sensor are electrically connected to the controller, and both the temperature display 12 and the humidity display 13 are electrically connected to the controller. Thus, the detection data from the temperature sensor and the humidity sensor can be displayed on the temperature display 12 and the humidity display 13, respectively. Therefore, the operator can control the opening and closing of the hot air generator 5 and the water mist generator 6 by using the buttons according to the data in the temperature display 12 and the humidity display 13, until the temperature and humidity in the user's actual processing environment are reached.

[0028] Specifically, such as Figure 2 and Figure 5 As shown, a pair of slide rails 21 are fixedly installed on the testing table 2. The slide rails 21 are located on the side of the positioning seat 3 away from the testing door 11. The slide rails 21 extend in the X-axis direction, which is the length direction of the positioning seat 3. A movable seat 22 is slidably installed on the slide rails 21, and the flatness tester 7 is installed on the movable seat 22. The movable seat 22 is equipped with a drive mechanism 8 for adjusting the flatness tester 7 to move in the Y-axis and Z-axis directions. A first slide block 23 is fixedly installed on the movable seat 22, and a first adjusting seat 24 slides in the Y-axis direction. The direction is closer to or further away from the positioning seat 3; a second slide 25 is fixedly installed on the first adjusting seat 24, and a second adjusting seat 26 slides on the second slide 25 in the Z-axis direction, which is vertical; the flatness measuring instrument 7 is fixedly installed on the second adjusting seat 26; the driving mechanism 8 includes a Y-axis driving component for driving the first adjusting seat 24 to slide and a Z-axis driving component for driving the second adjusting seat 26 to slide; thus, the flatness measuring instrument 7 can be finely adjusted in the Y-axis direction and the Z-axis direction by the Y-axis driving component and the Z-axis driving component respectively.

[0029] The Y-axis drive assembly includes a fixed seat 81 and a screw 82. The fixed seat 81 is fixedly mounted on the first slide 23. The screw 82 extends in the Y-axis direction and is threaded onto the fixed seat 81. One end of the screw 82 is rotatably mounted on the first adjusting seat 24 via a bearing, and the other end of the screw 82 is for the operator to rotate. Thus, by turning the screw 82, the first adjusting seat 24 is driven to slide, thereby achieving fine adjustment of the flatness measuring instrument 7 in the Y-axis direction.

[0030] like Figure 5 and Figure 6 As shown, The second slide 25 has a dovetail groove 251 extending in the Z-axis direction. The second adjusting seat 26 is equipped with a dovetail block 261, which is slidably installed in the dovetail groove 251. The Z-axis drive assembly includes a drive rack 83, a drive gear 84, a rotating shaft 85, and a limiting member. The drive rack 83 extends in the Z-axis direction and is fixedly installed in the dovetail block 261. The rotating shaft 85 is rotatably installed in the second slide 25. The rotating shaft 85 extends in the horizontal direction, with one end extending into the dovetail groove 251 and the other end extending out of the second slide 25. The drive gear 84 is sleeved and fixedly installed at the end of the rotating shaft 85 located in the dovetail groove 251. The drive rack 83 and the drive gear 84 mesh. Thus, the rotating shaft 85 can be turned to drive the drive gear 84 to rotate, thereby driving the second adjusting seat 26 to slide in the vertical direction, thereby achieving fine adjustment of the flatness measuring instrument 7 in the vertical direction.

[0031] The limiting component is used to restrict the sliding position of the second adjusting seat 26. The limiting component includes a locking bolt 86 and a rubber strip 87. The locking bolt 86 is threaded onto the second slide 25. One end of the locking bolt 86 extends into the dovetail groove 251, and the other end of the locking bolt 86 protrudes out of the second adjusting seat 26. The rubber strip 87 is rotatably mounted on the end of the locking bolt 86 located in the dovetail groove 251 via a bearing. The rubber strip 87 abuts against the side wall of the dovetail block 261. Thus, by turning the locking bolt 86, the rubber strip 87 can be driven to move closer to or further away from the dovetail block 261, thereby locking the position of the second adjusting seat 26.

[0032] The implementation principle of the blade flatness detection device in this application embodiment is as follows: During detection, the blade is inserted into the slot 31 with the cutting edge facing vertically upward; then the first drive member 42 and the second drive member 44 are activated to drive the clamping block and the lowering block 43 to move towards the positioning seat 3, thereby confining the blade within the slot 31 and completing the stable positioning of the blade; then the detection door 11 is closed, and the hot air generator 5 and the water mist generator 6 are activated to simulate the temperature and humidity in the user's processing environment in the detection chamber 1; after maintaining this for a period of time, the detection door 11 is opened, the sliding seat 22 is moved, thereby driving the flatness detector 7 to move along the length direction of the blade, and the flatness of the blade at various positions along the length direction of the cutting edge is detected by the flatness detector 7.

[0033] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0034] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
