Description
Technical Field
The utility model relates to a tensioning adjustment mechanism especially relates to a 3D printer hold-in range tensioning adjustment mechanism.
Background
At present, the synchronous belt adjusting mechanism on the market has the following problems and disadvantages: 1. the mechanism is compressed tightly through two screws, and the tensioning degree of hold-in range can not accurate regulation. 2. Synchronous pulley has adopted two flange bearing equipment, and although the rotation effect is better, the rusty condition can appear in long-time work. 3. Synchronous pulley has adopted two flange bearing equipment, and the flange bearing is the plain noodles, and long-time work can cause the damage to the flank of tooth of hold-in range, influences hold-in range life. Therefore, it is an urgent problem to be solved by those skilled in the art to develop a mechanism for adjusting tension of a synchronous belt of a 3D printer.
SUMMERY OF THE UTILITY MODEL
The utility model relates to a solve the above-mentioned not enough, the utility model provides a 3D printer hold-in range tensioning adjustment mechanism.
The above object of the present invention is achieved by the following technical solutions: a synchronous belt tensioning and adjusting mechanism of a 3D printer comprises a mounting plate, a fixed seat and a synchronous belt wheel,
the mounting plate comprises a bottom plate and a vertical plate, the bottom plate is perpendicular to the vertical plate, mounting bolt holes are formed in the bottom plate, limiting plates are arranged on two sides of the bottom plate to form a translation chute, and first adjusting bolt holes are formed in the vertical plate;
the fixing base is "Contraband" shape to install in the translation spout between the limiting plate of mounting panel both sides, synchronous pulley is installed through the shaft bolt in opening one side of fixing base, seals one side and is equipped with second adjusting bolt hole, and adjusting bolt is installed to second adjusting bolt hole department, and adjusting bolt passes second adjusting bolt hole, first adjusting bolt hole from interior to exterior in proper order, and is connected with adjust knob in the riser outside.
Furthermore, the bottom of the fixing seat is provided with a locking bolt hole, a waist-shaped hole is formed in the bottom plate of the bottom side of the fixing seat, a locking bolt is installed on the bottom plate of the bottom side of the fixing seat, and the locking bolt penetrates through the waist-shaped hole and is connected to the locking bolt hole in the bottom of the fixing seat. When the fixing seat is adjusted to move horizontally, the locking bolt moves in the waist-shaped hole, and when the fixing seat is adjusted to a proper position, the locking bolt is locked.
Further, the synchronous pulley is a tooth surface synchronous pulley and is meshed with a tooth surface of the synchronous belt.
When the utility model is used, the utility model is fixed on the frame or other parts of the 3D printer through the mounting bolt, and the synchronous belt is wound around the synchronous belt wheel (namely, the synchronous belt wheel is mounted). When the synchronous belt is loosened, the synchronous belt can be accurately adjusted through the adjusting knob and is locked and positioned through the locking bolt. If the adjustment is too tight, the adjustment is reversed.
Compared with the prior art, the utility model the advantage be: will the utility model discloses integral erection adopts flank of tooth synchronous pulley and hold-in range meshing on the 3D printer, changes synchronous pulley's relative position through screw and knob to reach the tensioning pulling force of accurate regulation hold-in range, adjusted the screw locking through the vertical direction, effectively prevent that the mechanism is not hard up. The mechanism is convenient to install, labor-saving and simple to adjust, and the service life of the belt is not influenced after long-time work.

Detailed Description
The present invention will be described in detail with reference to the accompanying drawings.
As shown in fig. 1 to 5, a synchronous belt tensioning and adjusting mechanism of a 3D printer comprises a mounting plate 1, a fixed seat 2 and a synchronous pulley 3,
the mounting plate 1 comprises a bottom plate 101 and a vertical plate 102, the bottom plate 101 is perpendicular to the vertical plate 102, a mounting bolt hole 103 is formed in the bottom plate 101, limiting plates 104 are arranged on two sides of the bottom plate to form a translation chute 105, and a first adjusting bolt hole 106 is formed in the vertical plate 102;
Further, the bottom of the fixing base 2 is provided with a locking bolt hole (not shown), the bottom plate 101 at the bottom side of the fixing base 2 is provided with a waist-shaped hole 107, and the locking bolt 7 is installed, and the locking bolt 7 penetrates through the waist-shaped hole 107 and is connected to the locking bolt hole at the bottom of the fixing base 2. When the fixing base 2 is adjusted and translated, the locking bolt 7 moves in the waist-shaped hole 107, and when the fixing base 2 is adjusted to a proper position, the locking bolt 7 is locked.
Further, the timing pulley 3 is a tooth surface timing pulley, and is engaged with a tooth surface of the timing belt 8.
When in use, the utility model is fixed on the frame or other parts 10 of the 3D printer through the mounting bolts 9, and the synchronous belt is wound around the synchronous belt pulley 3 (namely, is arranged on the synchronous belt pulley 3). When the synchronous belt is loosened, the synchronous belt can be accurately adjusted through the adjusting knob 6 and is locked and positioned through the locking bolt 7. If the adjustment is too tight, the adjustment is reversed.
The above only is the embodiment of the present invention, not limiting the patent scope of the present invention, all the equivalent structures or equivalent processes that are used in the specification and the attached drawings or directly or indirectly applied to other related technical fields are included in the patent protection scope of the present invention.
