Description

Technical Field

[0001] This utility model relates to the field of 3D printing technology, and in particular to an automatic pre-compression linear conductor structure. Background Technology

[0002] Currently, the rollers of the printing platform are directly fixed with screws, or the guide rails on the base are clamped by adjusting and locking with eccentric columns to ensure that the printing platform does not shift when moving in the Y direction. However, screw fastening is not conducive to later maintenance and has the possibility of installation accuracy errors. The installation process of eccentric isolation columns is complicated and involves a large number of small assembly parts. When the error is large, the parts can only be replaced directly, which is very inconvenient and increases maintenance costs. Since the rollers are currently fixed by screws and then manually assembled and tightened with the guide rails, they are also prone to loosening during transportation or use, resulting in excessive gaps that affect the running accuracy of the guide rails and further affect the printing quality. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art and solve the existing technical problems, this utility model discloses an automatic pre-tightening linear guide structure, which ensures the clamping of the guide rail while facilitating assembly, adjustment and maintenance.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An automatic pre-compression linear conductor structure includes a platform plate and a guide rail. Multiple pulleys are rotatably mounted on the platform plate on both sides of the guide rail, such that the pulley surfaces roll and abut against corresponding sides of the guide rail. Pulleys on the same side of the guide rail are mounted on the platform plate via a clamping mechanism. The clamping mechanism includes a slider and a strip-shaped base plate. The strip-shaped base plate is fixed to the platform plate so that its end corresponds to a corresponding side of the guide rail. The outer surface of the strip-shaped base plate has a long groove along its length. The slider's two sides are engaged with the two groove walls and can slide along the length of the strip-shaped base plate. One end of the slider near the guide rail has a mounting platform protruding from the groove opening. A corresponding pulley is rotatably mounted on the mounting platform. An elastic element is provided between the other end face of the slider and the corresponding end of the groove. A threaded through hole is provided on the middle surface of the slider corresponding to the groove opening, and an adjusting screw is fitted into the threaded through hole.

[0006] Furthermore, four or six pulleys are symmetrically arranged on both sides of the guide rail.

[0007] Furthermore, each pulley on both sides of the guide rail is mounted on the platform plate via a clamping mechanism.

[0008] Furthermore, two spaced-apart guide rails are symmetrically arranged on both sides of the platform plate.

[0009] Furthermore, both inner walls of the long groove are provided with slots along the length of the long groove, and the corresponding side of the slider is fixed with a clip adapted to slide and be mounted in the slot.

[0010] Furthermore, two threaded through holes are provided along the length of the slider.

[0011] Furthermore, the corresponding end face of the slider is provided with a slot for the insertion of the end of the elastic element.

[0012] Furthermore, the strip seat plate is arranged perpendicular to the guide rail.

[0013] By adopting the technical solution described above, this utility model has the following beneficial effects:

[0014] The automatic pre-tightening linear guide structure disclosed in this utility model uses a slider, which is pressed by an elastic element in the long groove of the strip-shaped base plate. This ensures that the slider and the pulley mounted on the slider always tend to be close to the guide rail. During installation and adjustment, simply loosen the adjusting screw, and the elastic element will automatically eliminate the gap. Then, tighten the adjusting screw again. This effectively eliminates this part of the fit error. In addition, the entire structure is integrated and designed to reduce the number of parts, which is beneficial for users to maintain and repair. Adjusting the accuracy error is also simpler without disassembly or replacing parts, which can solve the accuracy problem and effectively reduce the product material, assembly and use costs.

[0019] The technical solution of this utility model will be described below with reference to the accompanying drawings of the embodiments of this utility model. In the description, it should be understood that if there are terms such as "upper", "lower", "front", "rear", "left", "right" indicating the orientation or positional relationship, they are only corresponding to the drawings of this utility model for the convenience of describing this utility model, and do not indicate or imply that the device or element referred to must have a specific orientation. Example 1:

[0020] Combined with appendix Figure 1-2 The aforementioned automatic pre-compression linear conductor structure includes a platform plate 6 and a guide rail 1. The platform plate 6 is a printing platform containing a heating plate and insulation cotton. Multiple pulleys 2 are rotatably mounted on the platform plate 6 on both sides of the guide rail 1. The wheel axle of the pulley 2 is vertically connected to the platform plate 6 so that the wheel surface of the pulley 2 rolls against the corresponding side of the guide rail 1. There can be three pulleys 2 on both sides of the guide rail 1, that is, two pulleys 2 on one side and one pulley 2 on the other side. However, it is preferable to have four or six pulleys 2 symmetrically arranged on both sides of the guide rail 1 to ensure clamping strength and stability.

[0021] As attached Figure 1 As shown, the two pulleys 2 on the left side of the guide rail 1 are mounted on the platform plate 6 via a clamping mechanism, while the two pulleys 2 on the right side of the guide rail 1 are directly mounted on the platform plate 6, since generally only one side of the guide rail 1 needs automatic pre-pressure adjustment. The clamping mechanism includes a slider 4 and a strip-shaped base plate 5. The plate surface of the strip-shaped base plate 5 is fixed to the platform plate 6 so that the end of the strip-shaped base plate 5 corresponds to the corresponding side of the guide rail 1. Usually, the strip-shaped base plate 5 is set perpendicular to the guide rail 1. The outer plate surface of the strip-shaped base plate 5 is provided with a length along the length of the strip-shaped base plate 5. The long groove 501 has two sides of the slider 4, which are engaged with the two groove walls of the long groove 501 and can slide along the length of the strip plate 5. This ensures that the slider 4 slides smoothly while preventing it from falling out of the groove opening of the long groove 501. Generally, the groove opening of the long groove 501 can be designed to be narrowed, or, as needed, grooves along the length of the long groove 501 can be provided on both inner groove walls of the long groove 501. The corresponding side of the slider 4 is fixed with a matching strip that is engaged with the groove. The sliding is limited by the matching of the strip and the groove.

[0022] The slider 4 has a mounting platform 402 exposed at the opening of the long groove 501 at one end near the guide rail 1. The corresponding pulley 2 is rotatably mounted on the surface of the mounting platform 402. The mounting platform 402 facilitates the installation and removal of the pulley 2 and ensures that the installation height is consistent with that of the corresponding pulley 2 on the other side of the guide rail 1. An elastic element 3, usually a spring, is provided between the end face of the slider 4 and the corresponding end of the long groove 501 to press the slider 4, so that the slider 4 and the mounted pulley 2 tend to move closer to the guide rail 1. If necessary, the corresponding end face of the slider 4 is provided with an adaptive elastic element. The slot 403 inserted into the end of component 3 limits the elastic element 3 and prevents it from dislodging from the long slot 501. The middle surface of the slider 4 corresponding to the opening of the long slot 501 is provided with a threaded through hole 401. An adjusting screw 7 is provided in the threaded through hole 401. By turning the adjusting screw 7, the slider 4 and the strip seat plate 5 are pressed together, thereby sliding and positioning the slider 4. In order to ensure stable positioning, there are generally two threaded through holes 401 along the length of the slider 4, and two adjusting screws 7 are turned for positioning.

[0023] When the automatic pre-tightening linear conductor structure of this utility model needs adjustment, first loosen the adjusting screw 7, and the slider 4 will be automatically pushed by the elastic element 3, so that the pulley 2 installed on the slider 4 can press against the corresponding side of the guide rail 1 to eliminate the gap. Then tighten the adjusting screw 7. Example 2:

[0024] As attached Figure 3 As shown, the difference from Embodiment 1 is that each pulley 2 on both sides of the guide rail 1 is installed on the platform plate 6 through a clamping mechanism. That is, regardless of the relative position of the guide rail 1 and the platform plate 6, the pulleys 2 on both sides can be adjusted accordingly. In addition, when the width of the platform plate 6 is large, two guide rails 1 can be symmetrically arranged side by side on both sides of the platform plate 6.

[0025] The parts of this utility model not described in detail are prior art. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that this utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the above embodiments should be regarded as exemplary and non-limiting in all respects. The scope of this utility model is defined by the appended claims rather than the foregoing description. Therefore, it is intended to include all changes that fall within the meaning and scope of the equivalents of the claims in this utility model, and no reference numerals in the claims should be regarded as limiting the content of the claims.
