Description

Flexible screw locking machine structure
Technical field
This utility model relates to a kind of automatic lock screws appts, especially a kind of flexible screw locking machine structure.
Background technology
Electric screwdriver is also electric screw driver, electric screw driver electricscrewdriver, it it is the electric tool for tightening and unscrew screw, this electric tool is equipped with the mechanism regulating and limiting moment of torsion, it is mainly used in assembly line, it is widely used in the industries such as aviation, automobile, machine, electrical equipment, for raising labour productivity, alleviating labor strength has significant effect.Produce in order to make electric screwdriver be applicable to assembly line, it is necessary to bindiny mechanism is set outside electric screwdriver.Connect the mechanism and the automatic locking screw machine that are provided with electric screwdriver in the market, the bindiny mechanism of existing automatic locking screw machine mostly is rigid connection mechanism, include cylinder, electric screwdriver and connect the contiguous block of cylinder and electric screwdriver, this mechanism in process of production due to the hole bit-errors that product space moves or product defects causes, can cause electric screwdriver directly batter product more serious may damage equipment.And the structure electric screwdriver shift position of rigid connection is also fixing, it is impossible to adapting to many height products, limitation is big;Also have to adopt Z-direction module and arrange multiple control point by PLC and control the height and position of electric screwdriver, although this Production requirement that can meet many height products, but its cost is relatively big, program debugging is complicated, nor it can be avoided that the fault caused because of positional fault or the defect defect of product own of product.
Utility model content
The damage of product that causes because of the positional fault of product or defect for solving above-mentioned existing automatic locking screw machine, device damage and can not meet the problem of many height production demands, the utility model discloses a kind of flexible screw locking machine structure.
This utility model be the technical scheme is that
A kind of flexible screw locking machine structure, including frame, cylinder and electric screwdriver, described cylinder is arranged on the top of described frame, described cylinder be connected below the first guide rod, described first guide rod is arranged with the first spring, the bottom of described first guide rod is connected to guide block, the side of described guide block and described electric screwdriver fix, described first guide rod is passed down through described guide block and is provided with the first limited block bottom it, the bottom of described frame is fixed with the second guide rod, described second guide rod is arranged with the second spring, the upper end of described second guide rod is connected with described guide block, described second guide rod is upward through guide block and is provided with the second limited block on its top.
Further, described first limited block and the second limited block are cylindrical piece.
Further, it is provided with link block between described first guide rod and cylinder.
Further, in described frame electric screwdriver be connected with location protection board.
nullAbove-mentioned technical solutions of the utility model are adopted to provide the benefit that: the disclosed a kind of flexible screw locking machine structure of this utility model,Cylinder stretches out promotion the first guide rod、Guide block and electric screwdriver move,Electric screwdriver moves into place and carries out lock screw work,First guide rod therein、Second guide rod、First spring、Second spring、Guide block has collectively constituted flexible linking device,In sleeve mechanism, the stroke of cylinder is certain,When product screw height and position difference,Because guide block is pressed downward against making the first spring by axial compressive force contraction distortion、Second spring is subject to axial tension stretcher strain,The axial stretching of flexibility can be carried out when making the bottom of electric screwdriver to bottom offset,Now electric screwdriver can with product height for restriction,Rather than the stroke of cylinder is restriction,Thus adapting to many height products,Without because product screw position not to or product defects cause electric screwdriver to product、The damage of equipment;And the second spring can effectively reduce the cylinder inertia impact when high-speed cruising, it is ensured that the stability of integrated model and life-span.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model flexibility screw locking machine structure;
Fig. 2 is the schematic perspective view of this utility model flexibility screw locking machine structure.
In figure, 1, frame 2, cylinder 3, electric screwdriver 31 protection boards the 4, first guide rod the 41, first limited block 5, link block the 6, first spring 7, guide block the 8, second guide rod the 81, second limited block the 9, second spring.
Detailed description of the invention
For making the purpose of this utility model embodiment, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described.Following example are only for clearly illustrating the technical solution of the utility model, and can not limit protection domain of the present utility model with this.
As depicted in figs. 1 and 2, a kind of flexible screw locking machine structure, including frame 1, cylinder 2 and electric screwdriver 3, described frame 1 is connected with location protection board 31 at electric screwdriver 3.Described cylinder 2 is arranged on the top of described frame 1, described cylinder 2 be connected below the first guide rod 4, it is provided with link block 5 between described first guide rod 4 and cylinder 2, described first guide rod 4 is arranged with the first spring 6, the bottom of described first guide rod 4 is connected to guide block 7, the side of described guide block 7 and described electric screwdriver 3 fix, described first guide rod 4 is passed down through described guide block 7 and is provided with the first limited block 41 bottom it, the bottom of described frame 1 is fixed with the second guide rod 8, described second guide rod 8 is arranged with the second spring 9, the upper end of described second guide rod 8 is connected with described guide block 7, described second guide rod 8 is upward through guide block 7 and is provided with the second limited block 81 on its top, described first limited block 41 and the second limited block 81 are cylindrical piece.
nullThe disclosed a kind of flexible screw locking machine structure of this utility model,Operationally,Cylinder 2 stretches out promotion the first guide rod 4、Guide block 7 and electric screwdriver 3 move,Electric screwdriver 3 moves into place and carries out lock screw work,First guide rod 4 therein、Second guide rod 8、First spring 6、Second spring 9、Guide block 7 has collectively constituted flexible linking device,In sleeve mechanism, the stroke of cylinder 2 is certain,When product screw height and position difference,Because guide block 7 is pressed downward against making the first spring 6 by axial compressive force contraction distortion、Second spring 9 is by axial tension stretcher strain,The axial stretching of flexibility can be carried out when making the bottom of electric screwdriver 3 to bottom offset,Now electric screwdriver 3 can with product height for restriction,Rather than the stroke of cylinder 2 is restriction,Thus adapting to many height products,Without because product screw position not to or product defects cause electric screwdriver to product、The damage of equipment;And the second spring 9 can effectively reduce the cylinder 2 inertia impact when high-speed cruising, it is ensured that the stability of integrated model and life-span.
Last it is noted that the foregoing is only preferred embodiment of the present utility model, it is not limited to this utility model, although this utility model being described in detail with reference to previous embodiment, for a person skilled in the art, technical scheme described in foregoing embodiments still can be modified by it, or wherein portion of techniques feature carries out equivalent replacement.All within spirit of the present utility model and principle, any amendment of making, equivalent replacement, improvement etc., should be included within protection domain of the present utility model.
