Abstract
The utility model discloses a kind of mechanical control arm of spanner, comprise support, universal bearing, hinged block, linking arm and linking springs, support is connected by hinged block with linking arm, the junction of support and hinged block is provided with universal bearing, linking springs and linking arm be arranged in parallel, its one end is connected with hinged block, the other end and linking arm side affixed, linking arm end is provided with the securing member be connected with spanner.The utility model makes the operation of spanner more flexible and the maximum position of restriction electric wrench, plays protection spanner.
Description
Technical field
The utility model relates to a kind of Wrench, especially a kind of mechanical control arm of spanner.
Background technology
The bolt tightening of automotive seat, adopt Electric torque wrench, the moment of torsion that seat tights a bolt can be ensured, electric tightening spanner output torque is stablized, but the volume of spanner is excessive, preponderance, long-time operation is inconvenient, and the scope of activities of spanner is unrestricted, frock easily encountered by spanner or line body causes workpiece damage.
Utility model content
The purpose of this utility model is the mechanical control arm providing a kind of spanner, makes the operation of spanner more flexible and the maximum position of restriction electric wrench, plays protection spanner.For achieving the above object, the utility model is by the following technical solutions:
A kind of mechanical control arm of spanner, be connected with spanner, comprise support, universal bearing, hinged block, linking arm and linking springs, described support is connected by hinged block with linking arm, described support and the junction of hinged block are provided with universal bearing, and described linking springs and linking arm be arranged in parallel, and its one end is connected with hinged block, the other end and linking arm side affixed, described linking arm end is provided with the securing member be connected with spanner.
Wherein, described linking arm comprises the first straight-arm, the second straight-arm and is positioned at the second middle hinged block, the second described straight-arm is connected with the first straight-arm by the second hinged block, and the hinged block above the first described straight-arm and universal bearing is hinged, and described securing member is positioned at the second straight-arm end.
After adopting technique scheme, the utility model tool has the following advantages: 1, adopt universal bearing, make the flexible operation of mechanical arm, is easy to operation, limits again the maximum position of electric wrench simultaneously, shields to electric wrench; 2, linking arm is provided with linking springs, can control the motion of linking arm, and after external force is removed, stretchy linking arm resets, and plays vibration damping and energy storage simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Primary clustering symbol description:
1: support, 2: universal bearing, 3: hinged block, 4: linking arm, 41: the first straight-arms, 42: the second straight-arms, 43: the second hinged blocks, 5: linking springs, 6: securing member.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.
Refer to shown in Fig. 1, this novel mechanical control arm disclosing a kind of spanner, be connected with spanner, comprise support 1, universal bearing 2, hinged block 3, linking arm 4 and linking springs 5, connect 4 arms and comprise the first straight-arm 41, second straight-arm 42 and be positioned at the second middle hinged block 43, second straight-arm 42 is connected with the first straight-arm 41 by the second hinged block 43, support 1 is connected by hinged block 3 with the first straight-arm 41, support 1 is provided with universal bearing 2 with the junction of hinged block 3, first straight-arm 41 is hinged with the hinged block 3 above universal bearing 2, second straight-arm 42 end is provided with securing member 6.Linking springs 5 and the first straight-arm 41 be arranged in parallel, and its one end is connected with hinged block 3, the other end and the first straight-arm 41 side affixed.
As the schematic diagram that bold portion in Fig. 1 is linking arm 4 contraction state, now linking springs 5 in the raw, and when electric wrench starts, universal bearing 2 rotates, linking arm 4 launches, as dotted line part in figure for shown in, now linking springs 5 is stretched, storage elasticity potential energy, second straight-arm 42 controls the capable effect station that moves to of spanner and tights a bolt, after tightening, linking springs release elastic potential energy, the first straight-arm 41 and the second straight-arm 42 are retracted to original position.
The mechanical control arm adopting this novel, for spanner, may make the operation of spanner more flexible, with the maximum position of limit electric wrench, shield to electric wrench, can meet production, reach the demand of producing 68UPH.
The above, be only the utility model preferably detailed description of the invention, is anyly familiar with those skilled in the art in the technical scope that the utility model discloses, the change that can expect easily or replacement, all should be encompassed within protection domain of the present utility model.
