The invention provides a device for replacing a printing substrate of a 3D printer, which comprises a substrate 1 and a bottom plate 2. As shown in fig. 1 and 5, a positioning block 11 is mounted at the bottom of the substrate 1, and two clamping grooves 111 are formed on two sides of the positioning block 11.
As shown in fig. 3-6, the top of the bottom plate 2 is provided with a positioning groove 23 and a receiving groove 22 which are communicated with each other, and the positioning groove 23 is used for receiving the positioning block 11, and the shape and the size of the positioning block are matched with those of the positioning block 11. The positioning groove 23 comprises a first side (i.e. right side) and a second side (i.e. left side) which are oppositely arranged, wherein the first side is provided with a driving locking piece 41, the second side is provided with a driven locking piece 42, and the heads of the driving locking piece 41 and the driven locking piece 42 can be inserted into the clamping groove 111. The driving lock piece 41 and the driven lock piece 42 are both provided in the accommodation groove 22, and the side walls of the accommodation groove 22 restrict movement of both in the front-rear direction, and are movable only in the left-right direction. The accommodating groove 22 is also provided with a first connecting rod 6, a second connecting rod 7 and a third connecting rod 8, and the second connecting rod 7 is hinged in the accommodating groove 22 through a first rotating shaft 71. Specifically, the first rotating shaft 71 is an optical axis bolt, a bolt section of which is in threaded connection with the bottom plate 2, and the middle part of the second connecting rod 7 is sleeved on the optical axis section of the second connecting rod and can rotate around the optical axis section of the second connecting rod.
The driving locking piece 41 is fixedly connected with the first end of the first connecting rod 6, the second end of the first connecting rod 6 is hinged with the first end of the second connecting rod 7, the second end of the second connecting rod 7 is hinged with the first end of the third connecting rod 8 through a second rotating shaft 81, the third connecting rod 8 is L-shaped, and the second end of the third connecting rod 8 is provided with a thimble 32 for propping up the tail of the driven locking piece 42. As shown in fig. 1-6, an opening 21 is further formed on one side (i.e., the right side) of the bottom plate 2, which is close to the active locking piece 41, and an adjusting post 31 for pushing against the tail of the active locking piece 41 is disposed in the opening 21. Specifically, one end of the adjusting column 31, which is close to the active locking block 41, is in a cone shape without threads, and the shape of the adjusting column is the same as that of the thimble 32; the middle part of the adjusting column 31 is in threaded connection with the opening 21; the end of the adjusting column 31 remote from the active locking piece 41 is a hexagon socket head cap.
As can be seen from fig. 5 and 6, an active locking piece groove 411 is formed at the bottom of the active locking piece 41, and a first spring 51 is disposed in the active locking piece groove 411; a driven locking piece groove 421 is formed in the bottom of the driven locking piece 42, and a second spring 52 is arranged in the driven locking piece groove 421.
The working principle of the invention is as follows:
When the base plate 1 is separated from the base plate 2, the adjusting column 31 is located at a position close to the outer side in the opening 21, the adjusting column 31/the thimble 32 does not apply a pushing force to the driving locking piece 41/the driven locking piece 42, and the first spring 51 and the second spring 52 are both in a natural state. The head of the driving locking piece 41/the driven locking piece 42 is positioned outside the positioning groove 23 due to the first spring 51/the second spring 52, so that the head of the driving locking piece 41/the driven locking piece 42 does not block the positioning block 11 from entering the positioning groove 23.
When the substrate 1 is mounted on the base plate 2, the positioning block 11 positioned at the bottom of the substrate 1 is inserted into the positioning groove 23. After the lower surface of the base plate 1 contacts the upper surface of the base plate 1, a screwdriver may be inserted into the opening 21 and the adjustment column 31 may be rotated to move the adjustment column 31 leftward. During the leftward movement of the adjusting column 31, the adjusting column 31 drives the active locking piece 41 to move leftward, and the head of the active locking piece 41 is gradually inserted into the adjacent clamping groove 111; meanwhile, the driving locking piece 41 drives the third connecting rod 8 to swing anticlockwise through the first connecting rod 6 and the second connecting rod 7, the thimble 32 is driven to move rightwards, the thimble 32 drives the driven locking piece 42 to move rightwards, and the head of the driven locking piece 42 is gradually inserted into the adjacent clamping groove 111. Under the limitation of the side wall of the accommodating groove 22, the driving locking piece 41 and the driven locking piece 42 simultaneously move in opposite directions for the same distance, and the positioning block 11 is tightly propped, so that the substrate 1 cannot be separated from the bottom plate 2 upwards. According to the invention, the jacking mechanism is arranged in the bottom plate 2, so that the limit of the positioning block 11 and the substrate 1 in the front-back, left-right, up-down directions is realized, and the substrate 1 is fixed.
In one embodiment of the present invention, the positioning block 11 is disposed at the bottom center of the substrate 1, so as to facilitate positioning and installation. The bottom of the clamping groove 111 is provided with a first inclined plane, and the outer side height of the first inclined plane is smaller than the inner side height. The lower parts of the heads of the driving locking piece 41 and the driven locking piece 42 are respectively provided with a second inclined surface matched with the first inclined surface. By the cooperation of the first inclined surface and the second inclined surface, the locking force of the driving locking piece 41/the driven locking piece 42 to the clamping groove 111 can be increased.
Preferably, as shown in fig. 4, a locking piece cover plate 4 is respectively arranged at the top of the driving locking piece 41 and the driven locking piece 42, the locking piece cover plate 4 is detachably connected with the bottom plate 2 through bolts, and the locking piece cover plate can limit the driving locking piece 41/the driven locking piece 42 in the up-down direction, so that the driving locking piece 41/the driven locking piece 42 can only move left and right.
As shown in fig. 4 to 6, a spring cover plate 5 is provided on each of the first side and the second side of the positioning groove 23, and a through hole is provided in the spring cover plate 5 for passing through the head of the driving locking piece 41 or the head of the driven locking piece 42. One end of the first spring 51/the second spring 52 is fixed on the spring cover plate 5, and the other end is abutted against the side wall of the driving locking piece groove 411/the side wall of the driven locking piece groove 421. The first spring 51/second spring 52 provides the driving locking piece 41/driven locking piece 42 with an elastic force away from the positioning groove 23, and when the adjusting post 31/thimble 32 pushes against the driving locking piece 41/driven locking piece 42, the elastic force of the first spring 51/second spring 52 needs to be overcome.
As shown in fig. 3,4 and 6, the second end of the first connecting rod 6 is provided with a plug 61, the first end of the second connecting rod 7 is provided with a jack matched with the plug 61, and the plug 61 and the jack are hinged in a matched mode.
The invention further provides a 3D printer, which comprises the device for replacing the printing substrate of the 3D printer.
The foregoing is merely a preferred embodiment of the present invention, and it should be noted that modifications and substitutions can be made by those skilled in the art without departing from the technical principles of the present invention, and these modifications and substitutions should also be considered as being within the scope of the present invention.
