[0039] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0040] like Figures 1 to 12 As shown, the embodiment of the utility model provides a leveling locking assembly, which includes a base 10, a leveling seat 20, a locking member 30 and a leveling member 40. The base 10 has a first mating surface 11, the leveling seat 20 is movably arranged on the base 10, the leveling seat 20 has a mounting surface 21 and a second mating surface 22, and is used to lock the locking member 30 of the platform fixing frame 60. The leveling member 40 includes a wedge block 41 and at least two adjusting members 42. The wedge block 41 has a third mating surface 411 and a fourth mating surface inclined to the third mating surface 411. The third mating surface 411 is slidably matched with the first mating surface 11, and the fourth mating surface 412 is matched with the second mating surface 22. The adjusting member 42 is arranged between the base 10 and the wedge block 41. At least two adjusting members 42 have a locking state and an adjusting state. When the adjusting member 42 is in the locking state, the adjusting member 42 limits the sliding of the wedge block 41 along the first mating surface 11. When the adjusting member 42 is in the adjusting state, the adjusting member 42 allows the wedge block 41 to slide along the first mating surface 11 and drives the leveling seat 20 to swing relative to the base 10.

[0041] like Figure 6 to Figure 7 As shown, the leveling member 40 includes two adjusting members 42 , and the adjusting directions of the two adjusting members 42 are both set at an angle with the third matching surface 411 , and the adjusting directions of the two adjusting members 42 are set at an angle with each other.

[0042] Preferably, if Figure 6 to Figure 7 As shown, the leveling locking assembly includes four leveling members 40 , and each leveling member 40 includes two adjusting members 42 that are perpendicular to each other.

[0043] like Figure 6 to Figure 7As shown, the two adjusting members 42 include a first adjusting screw and a second adjusting screw. The first adjusting screw passes through the base 10 and the wedge block 41 along its extension direction, and the second adjusting screw passes through the leveling seat 20, the wedge block 41 and the base 10 along its extension direction. When adjusting the position of the wedge block 41, the first adjusting screw can be loosened and the second adjusting screw can be screwed to change the position of the wedge block 41. After the position of the wedge block 41 meets the requirements, the loosened first adjusting screw can be tightened again to fix the wedge block 41.

[0044] like Figures 4 to 9 As shown, the base 10 includes a top plate 12 and a side plate 13, the upper end of the side plate 13 is connected to the top plate 12, and the leveling seat 20 is movably arranged below the top plate 12. There is a gap between the leveling seat 20 and the top plate 12, and the second adjusting screw can pass through the top plate 12 (such as Figure 7 As best shown), the first adjusting screw passes through the side plate 13 along its extension direction (as shown in FIG. Figure 8 As best shown, the first mating surface 11 is disposed on the inner side wall of the side plate 13. The base 10 with the above structure is adopted so that the base 10 and the leveling base 20 are compactly installed.

[0045] like Figures 3 to 9 As shown, the leveling seat 20 includes an adjustment plate 23, a mounting plate 24 and a connecting frame 25. The adjustment plate 23 is movably arranged on the base 10, the second mating surface 22 is arranged on the side of the adjustment plate 23 away from the top plate 12, the mounting plate 24 is arranged parallel to the adjustment plate 23 on the side of the adjustment plate 23 away from the top plate 12, the mounting surface 21 is arranged on the side of the mounting plate 24 facing the adjustment plate 23, the connecting frame 25 is arranged between the adjustment plate 23 and the mounting plate 24, and the connecting frame 25 is respectively connected to the adjustment plate 23 and the mounting plate 24.

[0046] Preferably, the connecting frame 25, the adjusting plate 23 and the mounting plate 24 are of an integrally formed structure.

[0047] like Figure 3 , Figure 5 as well as Figure 6As shown, the leveling seat 20 includes two leveling plates 23 spaced apart along a first direction (e.g., a transverse direction), the first direction being parallel to the second mating surface 22, and two leveling members 40 spaced apart along a second direction on each leveling plate 23, the second direction being parallel to the second mating surface 22 and perpendicular to the first direction. With the above structure, four wedge blocks 41 of the leveling members 40 are disposed between the leveling seat 20 and the base 10. The inclination of the mounting surface 21 relative to the base 10 is changed by the movement of the wedge blocks 41 in the four leveling members 40. The four wedge blocks 41 are distributed at four corners, and the movement of each wedge block 41 can adjust the movement of the corresponding part of the leveling seat 20 (usually a slight displacement), so that the four wedge blocks 41 can adjust the position state (e.g., height) of any corner part of the leveling seat 20 to achieve the purpose of leveling.

[0048] like Figure 3 and Figure 5 As shown, the leveling seat 20 includes two mounting plates 24, and the two mounting plates 24 are arranged along a first direction.

[0049] In this embodiment, two side plates 13 are disposed opposite to each other on both sides of the leveling seat 20, and the top plate 12 and the two side plates 13 are surrounded by a mounting groove. During assembly, the leveling seat 20 is moved in the mounting groove to complete the installation.

[0050] In this embodiment, the top plate 12 is perpendicular to the side plate 13 , the two adjusting members 42 in each leveling member are respectively arranged perpendicular to the top plate 12 and the side plate 13 , and the second matching surface 22 is parallel to the top plate 12 .

[0051] In this embodiment, the wedge block 41 has a threaded hole and a through hole, the first adjusting screw is inserted into the threaded hole and threadably engaged with the threaded hole, the second adjusting screw is inserted into the through hole, and the diameter of the through hole is larger than the outer diameter of the second adjusting screw. After the wedge block 41 slides along the first mating surface 11, the second adjusting screw can still be engaged with the screw hole of the side plate 13.

[0052] For example, when other test data indicates that the build platform needs to be leveled, you can use the up operation or down operation:

[0053] (1) The upward adjustment operation (i.e., a part of the molding platform needs to be moved upward, and the corresponding corner of the leveling seat 20 needs to be adjusted to move upward) is as follows: find the leveling piece 40 corresponding to the corner of the leveling seat 20 that needs to be adjusted, loosen the second adjustment screw of the leveling piece 40, and turn the first adjustment screw to shorten the threaded mating portion of the second adjustment screw and the wedge block 41. The wedge block 41 slides along the first mating surface 11, so that the wedge block 41 moves outward and rises toward the top plate 12, thereby causing the corresponding part of the leveling plate 23 or the top plate 12 in contact with the wedge block 41 to rise (reducing the gap between the leveling plate 23 and the inner surface of the top plate 12), so that the corresponding part of the mounting surface 21 rises, thereby driving the molding platform thereon to rise;

[0054] (2) The downward adjustment operation (i.e., a part of the forming platform needs to be moved downward, and the corresponding corner of the leveling seat 20 needs to be adjusted to move downward) is as follows: find the leveling piece 40 corresponding to the corner of the leveling seat 20 that needs to be adjusted, loosen the second adjustment screw of the leveling piece 40, and turn the first adjustment screw to lengthen the threaded mating portion of the first adjustment screw and the wedge block 41. The screw head of the first adjustment screw drives the leveling plate 23 to move downward, and the wedge block 41 slides along the first mating surface 11. At the same time, the wedge block moves inward and descends, so that the corresponding part of the mounting surface 21 descends, thereby driving the forming platform thereon to descend.

[0055] like Figure 3 As shown, in this embodiment, the locking member 30 includes a wrench assembly 31 and at least two abutting members 32. The abutting members 32 are movably arranged on the leveling seat 20 in a direction perpendicular to the mounting surface 21. The wrench assembly 31 is arranged on the base 10 and is drivingly connected with the at least two abutting members 32 to drive the at least two abutting members 32 to synchronously approach or move away from the mounting surface 21. The movement of the two abutting members 32 can be controlled by a single wrench assembly 31. The two abutting members 32 are synchronously approached to the mounting surface 21 by the downward movement of the wrench assembly 31, and are synchronously moved away from the mounting surface 21 by the upward movement of the wrench assembly 31, thereby reducing the processing cost and precision requirements, and facilitating operation.

[0056] like Figure 3 and Figure 4 As shown, the abutment member 32 includes a lifting member 321, a pressure block 322 and an elastic member 323. The lifting member 321 is movably arranged on the leveling seat 20 in a direction perpendicular to the mounting surface 21. The wrench assembly 31 is drivingly connected to the lifting member 321. The pressure block 322 is arranged on the side of the lifting member 321 facing the mounting surface 21. The two ends of the elastic member 323 are respectively connected to the lifting member 321 and the pressure block 322. In the abutment member 32 with the above structure, the elastic member 323 can be used to improve the clamping effect of the pressure block 322 and the mounting surface 21 on the platform mounting frame.

[0057] In this embodiment, an abutment groove 61 is provided on the upper surface of the platform fixing frame, and the pressure block 322 can extend into the abutment groove 61. When the pressure block 322 extends into the abutment groove 61 and is pressed against the bottom wall of the abutment groove 61, the pressing block 33 presses the platform fixing frame 60 against the mounting surface 21, thereby locking the platform fixing frame 60 on the mounting surface 21.

[0058] In addition to the contents described and illustrated herein, the structure of the wrench assembly 31 may also refer to the corresponding contents in patent document CN218928644U, the entire contents of which are incorporated herein by reference.

[0059] In this embodiment, the leveling locking assembly further includes a photoelectric transmitter and a photoelectric receiver, both of which are arranged on the leveling seat 20. When the locking member 30 is in a compressed state, the abutment member 32 is located between the photoelectric transmitter and the photoelectric receiver. The above design facilitates judging whether the abutment member 32 is compressing the platform mounting frame.

[0060] As an example, a baffle 3211 is provided on the lifting member 321. When the locking member 30 is in a compressed state, the baffle 3211 is located between the photoelectric transmitter and the photoelectric receiver (preferably as Figure 3 shown).

[0061] like Figure 6 As shown, the base 10 is provided with an escape opening 14, and the abutment member 32 is passed through the escape opening 14. With the above structure, the base 10 and the locking member 30 are compactly installed.

[0062] In this embodiment, the locking member 30 is arranged on the leveling seat 20, and the locking member 30 has a locked state and an unlocked state. When the locking member 30 is in the locked state, the locking member 30 can lock the platform fixing frame 60 on the mounting surface 21. When the locking member 30 is in the unlocked state, the locking member 30 allows the platform fixing frame 60 to be separated from the mounting surface 21.

[0063] The locking mechanism may have alternative configurations. Figures 10 to 12As shown, in another embodiment, the locking member 30 includes a clamping block 33, an operating screw 34, a first nut 35 and a second nut 36. The clamping block 33 is movably arranged on the leveling seat 20 in a direction perpendicular to the mounting surface 21. The clamping block 33 is fixedly engaged with the leveling seat 20. The operating screw 34 is arranged perpendicular to the mounting surface 21. The operating screw 34 is rotatably arranged on the clamping block 33 around its axis. The operating screw 34 is rotatably arranged on the leveling seat 20 around its axis and is threadedly engaged with the leveling seat 20. The first nut 35 and the second nut 36 are sleeved on the operating screw 34 and are threadedly engaged with the operating screw 34. The first nut 35 and the second nut 36 are respectively located on both sides of the clamping block 33 in the axial direction of the operating screw 34. In the axial direction of the operating screw 34, the distance between the first nut and the second nut is greater than or equal to the thickness of the clamping block. By rotating the operating screw rod 34 , the pressing block 33 is driven to approach or move away from the mounting surface 21 , so that the processing cost of the locking member 30 is low and the precision requirement is low.

[0064] In this embodiment, the abutment 32 is made of an elastic material (such as rubber, polyurethane), and the surface of the clamping block 33 is provided with a hardened structure 331. The hardened structure 331 can be formed by directly hardening the surface of the clamping block, or the hardened structure 331 can be a hardened plate provided on the clamping block 33 to avoid the risk of fatigue stress.

[0065] In this embodiment, the outer diameters of the first nut 35 and the second nut 36 are larger than the diameter of the inner hole of the clamping block 33 for inserting the operating screw 34. For example, the operating screw 34 is rotated along the first rotation direction, so that the operating screw 34, the first nut 35 and the second nut 36 are raised relative to the base 10. After the second nut 36 moves a certain distance, the second nut 36 lifts the clamping block 33 to rise (that is, before the second nut 36 rises, there is a gap between the second nut 36 and the lower surface of the clamping block 33, and the second nut 36 is in contact with the lower surface of the clamping block 33), the clamping block 33 and the platform fixing frame 60 are separated, the locking of the platform fixing frame 60 is released, and the platform fixing frame 60 can be separated from the mounting surface 21. The operating screw 34 is rotated in a second rotation direction opposite to the first rotation direction, so that the operating screw 34, the first nut 35 and the second nut 36 descend relative to the base 10. After the first nut 35 moves a certain distance, the first nut 35 pushes the clamping block 33 to descend (that is, before the first nut 35 descends, there is a gap between the first nut 35 and the upper surface of the clamping block 33, and the first nut 35 is in contact with the upper surface of the clamping block 33). The clamping block 33 presses the platform fixing frame 60 against the mounting surface 21, thereby locking the platform fixing frame 60 on the mounting surface 21.

[0066] The application of the leveling locking assembly provided in this embodiment has the following beneficial effects:

[0067] (1) Compared with the cam locking assembly, the processing cost of the locking member 30 can be further reduced;

[0068] (2) One actuating wrench of the wrench assembly 31 is used to drive two abutment members 32, which enables quick operation;

[0069] (3) The locking member 30 and the leveling member 40 can be operated independently without affecting each other, thereby preventing the leveling effect from being affected by the locking operation and preventing the locking effect from being affected by the leveling operation;

[0070] (4) The installation fit between the locking member 30 and the leveling member 40 is compact, which helps to save the internal space of the 3D printing equipment cabin.

[0071] Another embodiment of the utility model provides a three-dimensional printing device, which includes a platform driving mechanism and a platform mechanism, wherein the platform driving mechanism is drivingly connected to the base 10 of the platform mechanism, and the platform mechanism includes a molding platform 50, a platform fixing frame 60, and a leveling locking assembly, wherein the platform fixing frame 60 is fixedly arranged on the molding platform 50, and the leveling locking assembly is the leveling locking assembly provided above. The three-dimensional printing device provided by this embodiment is applied, and the position of the wedge block 41 is adjusted by using the adjusting member 42, so that the third mating surface 411 is slidably matched with the first mating surface 11, and the inclination of the mounting surface 21 relative to the base 10 is adjusted until the requirement is met, and the platform fixing frame is placed on the mounting surface 21, and the platform fixing frame is locked on the mounting surface 21 by using the locking member 30. The locking member 30 and the leveling member 40 can be operated separately without affecting each other, so as to avoid the leveling effect being affected by the locking operation, and avoid the locking effect being affected by the leveling operation.
