Abstract
Description
Technical Field
[0001] This utility model belongs to the field of 3D printer technology, specifically a lifting limit adjustment device for 3D printers. Background Technology
[0002] In the field of 3D printing technology, the precise operation of a 3D printer depends on the coordinated operation of several key components, among which the lifting limit adjustment device plays a crucial role.
[0003] With the widespread application of 3D printing technology, the requirements for printing accuracy and stability are increasing. In existing technologies, many 3D printers have limitations in their positioning devices. Traditional positioning devices are mostly fixed structures and cannot be adjusted. This makes it impossible to flexibly adjust the positioning position when dealing with models of different sizes and printing needs. For example, when printing large models, fixed positioning devices may limit the effective lifting range of the printing platform, resulting in incomplete printing of the model. Conversely, when printing small, detailed models, non-adjustable positioning devices struggle to achieve high-precision positioning control, affecting print quality. Furthermore, fixed positioning devices, once subjected to mechanical wear or installation deviations during long-term use, are difficult to accurately correct, easily leading to printing malfunctions such as print head collisions with the printing platform. This not only damages equipment components but also increases maintenance costs and downtime.
[0004] Therefore, this utility model provides a lifting limit adjustment device for a 3D printer. Utility Model Content
[0005] To overcome the shortcomings of the prior art and solve at least one of the problems mentioned in the background art, a lifting limit adjustment device for 3D printers is proposed.
[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A lifting and limiting adjustment device for a 3D printer, comprising a clamping plate and a friction plate; two sets of clamping plates are provided, with a cylinder fixedly installed on one side of each set of clamping plates that is far apart from each other; fixing mechanisms are provided on both sides of the clamping plates; a tightening mechanism is provided on the inner wall of the cylinder; a supporting mechanism is provided on the inner wall of the cylinder; a buffer mechanism is provided on one side of the cylinder; a limiting component is provided on one side of the cylinder; the fixing mechanism includes a stud, a nut, and a connecting frame; two sets of connecting frames are provided, with both sets of connecting frames fixedly installed on both sides of the clamping plate; the stud is movably inserted into the inner wall of the connecting frame, and one end of the stud surface is threadedly installed with the nut; the connecting frame allows the user to easily fix the clamping plate using the stud and nut; the cooperation of the stud and nut allows the user to quickly install the clamping plate onto the printer, and also facilitates disassembly and replacement of other limiting parts of the printer.
[0007] Preferably, the tightening mechanism includes a screw, a knob, and an arc-shaped friction plate. The screw is threaded onto the side of the cylinder surface away from the clamping plate. The top of the screw is fixedly installed with the knob, and the bottom of the screw is rotatably installed with the arc-shaped friction plate. The arc-shaped friction plate is located on the inner wall of the cylinder and is movably installed with the cylinder. In this design, the combined use of the screw, knob, and arc-shaped friction plate can fix the cylindrical rod by the user's adjustment, preventing it from moving. At the same time, when it is necessary to adjust the limiting position, the user only needs to turn the knob so that the arc-shaped friction plate is no longer fixed to the cylindrical rod, allowing the angle of the arc-shaped ring to be adjusted freely by sliding.
[0008] Preferably, the support mechanism includes a fixed round rod, a support block, and a sliding rod. The fixed round rod is movably inserted into the inner wall of the cylinder. The end of the fixed round rod away from the cylinder is fixedly installed with the support block. The support block and the end of the fixed round rod on the inner wall away from the cylinder are slidably installed with the sliding rod. In this scheme, the cooperation of the fixed round rod, the support block, and the sliding rod can provide stable support for the buffer mechanism and the limiting component. At the same time, when adjustment is required, the buffer mechanism and the limiting component can be quickly adjusted.
[0009] Preferably, the buffer mechanism includes elastic plates, springs, and mounting brackets. Four sets of elastic plates are arranged in a ring and fixedly installed on the inner wall of the fixed cylindrical rod near the cylinder. The springs are fixedly installed on the support block away from the fixed cylindrical rod, located on the surface of the sliding rod. The end of the spring away from the support block is fixedly installed to the mounting bracket. In this design, the elastic plates enhance the spring's shock absorption efficiency, the springs provide primary shock absorption, preventing vibrations from each impact from the printer from affecting other printer components. The mounting brackets provide support for the limiting components and directly transmit the impact force received by the arc-shaped ring to the springs.
[0010] Preferably, the limiting component includes an arc-shaped ring and a rubber ring. The arc-shaped ring is fixedly installed on one side of the two sets of mounting brackets that are close to each other. The side of the arc-shaped ring away from the clamping plate is fixedly installed with the rubber ring. In this solution, the combined use of the arc-shaped ring and the rubber ring can directly limit the printer, prevent the printer from deviating, and keep it moving within the specified range. At the same time, the rubber ring can play a certain buffering role, and more importantly, it can prevent the arc-shaped ring from being damaged by the impact of the printer.
[0011] Preferably, the two sets of clamps are fixedly installed on the side of each other that is close to each other. In this scheme, the friction plate can increase the contact area between the clamps and the printer after installation, and at the same time increase the friction of the clamps, so that the clamps are not easy to loosen after installation, ensuring the stability of the clamps and improving the accuracy of the limit.
[0012] The beneficial effects of this utility model are as follows:
[0013] 1. The lifting limit adjustment device for a 3D printer described in this utility model, through the arrangement of studs, nuts, a connecting frame, a screw, a knob, and an arc-shaped friction plate, allows the user to easily fix the clamping plate using the studs and nuts. The use of studs and nuts allows the user to quickly install the clamping plate onto the printer, and also facilitates the disassembly and replacement of other limiting parts of the printer. The use of the screw, knob, and arc-shaped friction plate allows the user to fix the fixed round rod by adjusting it, preventing it from moving. At the same time, when it is necessary to adjust the limiting position, the user only needs to turn the knob to de-fix the fixed round rod, allowing the arc-shaped friction plate to slide and freely adjust the angle of the arc-shaped ring limiting.
[0014] 2. The lifting limit adjustment device for a 3D printer described in this utility model, through the setting of a fixed round rod, a support block and a sliding rod, enables the fixed round rod, the support block and the sliding rod to work together to provide stable support for the buffer mechanism and the limit component, and at the same time, enables the buffer mechanism and the limit component to be quickly adjusted when adjustment is required.

[0022] 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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0023] Specific implementation examples are given below.
[0024] like Figures 1 to 4 As shown in the embodiment of this utility model, a lifting limit adjustment device for a 3D printer includes a clamping plate 1 and a friction plate 80. Two sets of clamping plates 1 are provided, with a cylinder 2 fixedly installed on one side of the two sets of clamping plates 1 that are far apart from each other. Fixing mechanisms 3 are provided on both sides of the clamping plates 1, and a tightening mechanism 4 is provided on the inner wall of the cylinder 2. A supporting mechanism 5 is provided on the inner wall of the cylinder 2, and a buffer mechanism 6 is provided on one side of the cylinder 2. A limit component 7 is provided on one side of the cylinder 2. The fixing mechanism 3 includes a stud 31, a nut 32, and a connecting frame. 33. Two sets of docking frames 33 are provided, and the two sets of docking frames 33 are fixedly installed on both sides of the clamping plate 1. The stud 31 is movably inserted into the inner wall of the docking frame 33, and one end of the surface of the stud 31 is threadedly installed with the nut 32. The tightening mechanism 4 includes a screw 41, a knob 42 and an arc-shaped friction plate 43. The screw 41 is threadedly installed on the side of the cylinder 2 away from the clamping plate 1. The top of the screw 41 is fixedly installed with the knob 42, and the bottom of the screw 41 is rotatably installed with the arc-shaped friction plate 43. The arc-shaped friction plate 43 is located inside the cylinder 2. The inner wall of the cylinder 2 is movably installed with the cylinder 2. The support mechanism 5 includes a fixed round rod 51, a support block 52, and a sliding rod 53. The fixed round rod 51 is movably inserted into the inner wall of the cylinder 2. The end of the fixed round rod 51 away from the cylinder 2 is fixedly installed with the support block 52. The end of the support block 52 and the inner wall of the fixed round rod 51 away from the cylinder 2 are slidably installed with the sliding rod 53. The buffer mechanism 6 includes an elastic sheet 61, a spring 62, and a mounting bracket 63. Four sets of elastic sheets 61 are provided and are fixedly installed in a ring on the fixed round rod. On the inner wall of 51 near the cylinder 2, spring 62 is fixedly installed on the side of support block 52 away from fixed rod 51. Spring 62 is located on the surface of sliding rod 53. The end of spring 62 away from support block 52 is fixedly installed with mounting bracket 63. Limiting component 7 includes arc ring 71 and rubber ring 72. Arc ring 71 is fixedly installed on the side of two sets of mounting brackets 63 close to each other. The side of arc ring 71 away from clamping plate 1 is fixedly installed with rubber ring 72. The side of two sets of clamping plates 1 close to each other is fixedly installed with friction plate 80.
[0025] like Figures 1 to 4As shown, the connecting frame 33 allows users to easily fix the clamping plate 1 using studs 31 and nuts 32. The use of studs 31 and nuts 32 allows users to quickly install the clamping plate 1 onto the printer, and also facilitates disassembly and replacement of other limiting parts of the printer. The use of screw 41, knob 42, and arc-shaped friction plate 43 allows the user to fix the fixed round rod 51, preventing it from moving. When the limiting position needs to be adjusted, the user only needs to turn knob 42 to remove the arc-shaped friction plate 43 from fixing the fixed round rod 51, and then slide it to freely adjust the limiting angle of the arc-shaped ring 71. The use of fixed round rod 51, support block 52, and sliding rod 53 provides stable support for the buffer mechanism 6 and limiting component 7, and allows the buffer mechanism 6 and limiting component 7 to be quickly adjusted when needed. The speed can be adjusted. The elastic sheet 61 can enhance the shock absorption efficiency of the spring 62. The spring 62 plays a major shock absorption role, preventing the vibration generated by each impact of the printer from endangering other parts of the printer. The mounting bracket 63 can provide support for the limiting component 7 and can also directly transmit the impact force received by the arc ring 71 to the spring 62. The cooperation between the arc ring 71 and the rubber ring 72 can directly limit the printer, prevent the printer from deviating, and keep it moving within the specified range. At the same time, the rubber ring 72 can play a certain buffer role, and more importantly, can prevent the arc ring 71 from being damaged by the impact of the printer. The friction plate 80 can increase the contact area between the clamping plate 1 and the printer after installation, and at the same time increase the friction of the clamping plate 1, making the clamping plate 1 less prone to loosening after installation, ensuring the stability of the clamping plate 1, and improving the accuracy of the limit.
[0026] Working principle: During operation, first place the clamping plate 1 at the position where the printer needs to be limited. Then, connect the two sets of connecting brackets 33 through the studs 31 and nuts 32, so that the clamping plate 1 can be firmly clamped to the printer. Then, the user picks up the fixing rod 51, aligns it with the cylinder 2, and inserts it into the inside of the cylinder 2. At this time, the user can adjust the position of the limit by sliding the fixing rod 51. After the adjustment is completed, the user turns the knob 42 to drive the screw 41 to rotate. When the screw 41 rotates, it will push the arc-shaped friction plate 43 downward. When the arc-shaped friction plate 43 is pushed, it will press the fixing rod 51 tightly, so that it no longer has the sliding function. Then it can be used. During use, when the printer screw drives the printer to move, it will hit the rubber ring 7 when it reaches the limit position. 2. The arc-shaped ring 71, when impacted, compresses the spring 62 via the mounting bracket 63, and the spring 62 absorbs the impact force. If the impact force is large, the sliding rod 53 will slide towards the inner wall of the fixed round rod 51 due to the impact force. When it slides to the deepest point, the elastic plate 61 will be squeezed and deformed to buffer the impact force, ensuring that the impact force will not damage the printer and also effectively limit the position. When a small adjustment of the limit angle is required, the user can first turn the knob 42 to reverse it so that the screw 41 drives the arc-shaped friction plate 43 to move upward, so that the arc-shaped friction plate 43 is no longer pressed against the fixed round rod 51. At that time, the user can adjust the position of the arc-shaped ring 71 by hand, thereby achieving the effect of quickly adjusting the limit angle.
