Abstract
The utility model discloses a 3D prints and uses belt tightener, including a base, its characterized in that: be provided with a stiff end and an expansion end on the base, the gliding setting of expansion end is in on the base still be provided with on the base one with the expansion end is connected is used for the adjustment the lead screw adjustment mechanism of interval between expansion end and the stiff end all be provided with the belt mounting groove on expansion end and the stiff end. The utility model discloses overspeed device tensioner comprises with expansion end two parts the stiff end that sets up on the base member. Be connected through the screw rod between overspeed device tensioner's stiff end and the expansion end, thereby reach the accurate degree of relaxation of adjusting the belt through the advance and retreat of adjusting screw screw thread.
Description
Technical field
The utility model belongs to 3D and prints field, specifically a kind of 3D printing belt stretcher.
Background technology
It is a kind of emerging manufacture that 3D prints, and growth momentum is very swift and violent, and market is huge. But U.S., day, moral have occupied the leading of 3D printing market, the 3D of China prints industry still in the starting stage. Print industry in order to cultivate Chinese 3D, country starts planning, development 3D prints industry. Had increasing people's prophesy, 3D printing technique will be to start one of most important technology of the industrial revolution for the third time.
3D prints has high requirement to its printing precision, and the parts precision of 3D printer and assembly technology precision have great impact to its printing precision. Thereby the travelling mechanism of present stage 3D printer is mainly motor drives the operation of printhead to reach accurate location by belt, and wherein the lax margin of the relax level of belt and both sides belt has great impact to the positioning precision of printer. Under the state that conventional belt hold-down mechanism mainly still needs operating personnel that belt is manually strained now, be fixed, there is many drawbacks in this kind of mode of operation: 1, due to fixing under the state of the manual tension of needs, causing to install wastes time and energy, and greatly reduces the production efficiency of product. 2, the tightness of multi-pass operation belt cannot ensure that unanimously slackness difference is larger, causes printing precision difference larger; 3, two leather belt driving mechanisms, very easily cause power transmission shaft generation permanent deformation because both sides belt tension has bigger difference, thereby affect printing precision.
Summary of the invention
Technical problem to be solved in the utility model is the deficiency existing for above-mentioned prior art, and a kind of assembling and 3D printing belt stretcher that can fine adjustment belt tightness degree of being easy to is provided.
For solving the problems of the technologies described above, the utility model is achieved through the following technical solutions:
A kind of 3D printing belt stretcher, comprise a pedestal, it is characterized in that: on described pedestal, be provided with a stiff end and a movable end, what described movable end slided is arranged on described pedestal, on described pedestal, be also provided with one be connected with described movable end for adjusting the connecting screw rod of spacing between described movable end and stiff end, on described movable end and stiff end, be provided with belt mounting groove.
On described pedestal, be provided with guide rail, on described movable end, be provided with the chute coordinating with described guide rail.
The cross section of described guide rail is work type.
Described connecting screw rod is connected on described stiff end.
On described stiff end, there is screwed hole.
The utility model tensioning apparatus, is made up of stiff end and movable end two parts of being arranged on pedestal. Stiff end directly and pedestal connect into as a wholely, cause and simplify the structure, cut down finished cost. Movable end bottom is connected with pedestal, and pedestal exists work type guide rail, ensures that the fluency of its operation has strict specification and guiding to its traffic direction simultaneously, ensures its upper and lower belt keeping parallelism, has ensured the required precision of assembling. Between the stiff end of tensioning apparatus and movable end, be connected by screw rod, thereby reach the slackness of fine adjustment belt by the advance and retreat of adjusting screw(rod) screw thread.
Compared with prior art, the beneficial effects of the utility model are:
1. the utility model apparatus structure is simple, and handling ease is with low cost.
2. the utility model assembling is simple and convenient, has saved the operating time in a large number, has improved production efficiency.
3. the utility model can fine adjustment belt tension, has improved printing precision.
4. the utility model can effectively ensure that both sides belt tightness degree is identical, has avoided the distortion of power transmission shaft.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model belt stretcher.
Fig. 2 is the axonometric drawing of the utility model belt stretcher.
Wherein: 1 is pedestal, 2 is stiff end, and 3 is movable end, and 4 is work type guide rail, and 5 is connecting screw rod, and 6 is belt mounting groove.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, the utility model belt stretcher comprises pedestal 1, has stiff end 2 and movable end 3 in the upper end of pedestal 1, wherein stiff end 2 is fixedly connected with pedestal 1, there is chute in movable end 3 lower ends, is connected, thereby reaches guiding and sliding function with the guide rail on pedestal 1. It is the work type guide rail 4 of work type that guide rail can adopt cross section. Between stiff end 2 and movable end 3, be also connected with connecting screw rod 5. By being rotationally connected screw rod 5, regulate the distance between movable end 3 and stiff end 2, thereby reach the adjusting in short supply to belt tension.
Operation principle of the present utility model is:
As shown in Figure 2, in assembling process, regulate connecting screw rod 5 that distance between movable end 3 and stiff end 2 is reached farthest. Then one end of belt is utilized stiff end 2 fixing, the other end is fixed on movable end 3. Thereby the distance that regulates afterwards connecting screw rod 5 to further between stiff end 2 and movable end 3 realizes belt tension regulatory function.
