Abstract
The utility model discloses a kind of belt wheel back-up wrench, comprise matrix and auxiliary fixing device; Described matrix is provided with four projections, matrix is made into integration by disk and rectangular disk, and matrix is also provided with rectangular recess; Described auxiliary fixing device is one " L " arm, and auxiliary fixing device is connected with matrix by tight split nut; Belt wheel, by arranging four projections and auxiliary fixing device, is fixed by fixture by the utility model, as the aid of dismounting nut, improves the removal efficiency of belt wheel gear nut, alleviates workload.
Description
Technical field
The utility model relates to a kind of belt wheel back-up wrench, concretely, relates to a kind of spanner of the nut on fixed pulley disengage gear, belongs to mechanized equipment technical field.
Background technology
Along with continuous progress and the development of society, the requirement of people to quality of life constantly improves, and in machine tool, people wish that it uses more convenient operation, and its design is more humane.
As the female Time of the spiral shell on dismounting belt wheel, because gear and belt wheel are coaxial, during nut on disengage gear, belt wheel also can rotate with the direction of exerting oneself, power executed so just cannot export useful work, and most of power all exports with the kinetic energy form of belt wheel, nut dismounting cannot be got off, removing nut will waste time and energy when there is no instrument, wasting the take-down time greatly.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of belt wheel back-up wrench, can nut on more laborsaving disengage gear, improves removal efficiency.
The utility model adopts following technical scheme to realize goal of the invention:
A kind of belt wheel back-up wrench, comprises matrix and auxiliary fixing device; Described matrix is provided with four projections, matrix is made into integration by disk and rectangular disk, and matrix is also provided with rectangular recess; Described auxiliary fixing device is one " L " arm, and auxiliary fixing device is connected with matrix by tight split nut.
Further, described four projections and auxiliary fixing device are positioned at homonymy.
Further, project through described in and inlay slotted eye and be connected with belt wheel.
Compared with prior art, advantage of the present utility model and good effect are: belt wheel, by arranging four projections and auxiliary fixing device, is fixed by fixture by this belt wheel back-up wrench, as the aid of dismounting nut, improve the removal efficiency of belt wheel gear nut, alleviate workload.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model belt wheel back-up wrench.
Detailed description of the invention
Below in conjunction with accompanying drawing and preferred embodiment, the utility model is further described in detail.
Shown in Figure 1, comprise matrix 2 and auxiliary fixing device 4; Described matrix 2 is provided with four projections 1, matrix 2 is made into integration by disk and rectangular disk, and matrix 2 is also provided with rectangular recess 3; Described auxiliary fixing device 4 is one " L " arm, and auxiliary fixing device 4 is connected with matrix 2 by tight split nut 5.
Wherein, described four projections 1 and auxiliary fixing device 4 are positioned at homonymy; Described protruding 1 is connected with belt wheel by inlaying slotted eye.
User is when dismantling, after projection 1 on spanner matrix 2 is combined with belt wheel upper groove, width again by regulating tight split nut 5 to control between auxiliary fixing device 4 and matrix 2, makes auxiliary fixing device 4 can be affixed closely with belt wheel, thus better belt wheel must be fixed.
The above, be only detailed description of the invention of the present utility model, but protection domain of the present utility model is not limited thereto, and any change of expecting without creative work or replacement, all should be encompassed within protection domain of the present utility model.Therefore, the protection domain that protection domain of the present utility model should limit with claims is as the criterion.
