Abstract
The utility model discloses a kind of holder for installing pin shaft anti-rotation silk seat, it comprises the holder of band spacing ring; Described holder is connected with the fixed head being provided with screw; Described fixed head is provided with handle; On described fixed head, the diameter of screw is identical with the diameter of pin shaft anti-rotation silk seat screw; The overall diameter of described spacing ring and the interior diameter of mechanical pin-and-hole match.The utility model easily can realize the group of the pin shaft anti-rotation silk seat on the structural members such as various type swing arm, dipper, turntable to job requirements.
Description
technical fieldthe utility model belongs to excavator technical field, is specifically related to a kind of holder for installing pin shaft anti-rotation silk seat.
background technologythe structural members such as the various type swing arm of excavator, dipper, turntable are all provided with bearing pin, because excavator works out of doors throughout the year, bad environments, often there is play in bearing pin, cause pin bore wear excessively, lining premature wear or come off, the accident such as pin shaft baffle premature wear, pin shaft anti-rotation silk seat early fallout, in order to prevent bearing pin generation play, below bearing pin, weld anti-rotation silk seat.
When current welding anti-rotation silk seat, first with the position of various measurer determination anti-rotation silk seat, then mark with wax crayon.During welding, workman's hand heads on anti-rotation silk seat, another hand-held electrode holder weld, this welding method can not ensure the depth of parallelism of pin shaft anti-rotation device two seat shelves spacing, two seat medial surfaces, two seat upper surfaces are in the first-class requirement of same plane, easy generation skew dislocation, and inefficiency.
summary of the inventionthe purpose of this utility model solves prior art to there is the technical problem easily offseting dislocation, inefficiency, welding inconvenience, provides a kind of holder for installing pin shaft anti-rotation silk seat, to overcome the deficiencies in the prior art.
To achieve these goals, a kind of holder for installing pin shaft anti-rotation silk seat of the utility model, it comprises the holder of band spacing ring; Its main points are that described holder is connected with the fixed head being provided with screw; Described fixed head is provided with handle; On described fixed head, the diameter of screw is identical with the diameter of pin shaft anti-rotation silk seat screw; The overall diameter of described spacing ring and the interior diameter of mechanical pin-and-hole match.
The utility model structure is simple, easy to use, pin shaft anti-rotation silk seat is placed on fixed head and is close to the sidewall of holder, the screw of pin shaft anti-rotation silk seat aligns with the screw of fixed head, bolt is screwed into from fixed head screw until be screwed into pin shaft anti-rotation silk seat, spacing ring is inserted in mechanical pin-and-hole, makes holder upper surface be close to machinery, at this moment pin shaft anti-rotation silk seat is welded with machinery, back out bolt after having welded, then take off holder by handle.
accompanying drawing explanationfig. 1 is the utility model structural representation;
Fig. 2 is the utility model using state decomposing schematic representation.
In figure 1, spacing ring 2, holder 3, screw 4, handle 5, fixed head 6, pin shaft anti-rotation silk seat
detailed description of the inventionsee figures.1.and.2, the utility model it comprise band spacing ring 1 holder 2; Described holder 2 is connected with the fixed head 5 being provided with screw 3; Described fixed head 5 is provided with handle 4; On described fixed head, the diameter of screw 3 is identical with the diameter of pin shaft anti-rotation silk seat 6 screw; The overall diameter of described spacing ring 1 and the interior diameter of mechanical pin-and-hole match.
During use, pin shaft anti-rotation silk seat is placed on fixed head and is close to the sidewall of holder, the screw of pin shaft anti-rotation silk seat aligns with the screw of fixed head, bolt is screwed into from fixed head screw until be screwed into pin shaft anti-rotation silk seat, spacing ring is inserted in mechanical pin-and-hole, makes holder upper surface be close to machinery, at this moment pin shaft anti-rotation silk seat is welded with machinery, back out bolt after having welded, then take off holder by handle.Before positioning welding, by squeeze grip, the generation preventing pin shaft anti-rotation silk seat welding deformation to warp, ensure that two pin shaft anti-rotation silk seat upper surface places at grade.The simple frock that described pin shaft anti-rotation silk seat group is right easily can realize the group of the pin shaft anti-rotation silk seat on the structural members such as various type swing arm, dipper, turntable to job requirements.
