Description
Technical field
The utility model relates to a kind of anti-turn bolt device for screwing up, belongs to tightening machine technical field.
Background technology
In engineering machinery assembling process, the operating type that feed screw nut tightens, technical merit falls behind, and there is potential safety hazard in operating process, and the anti-rotation of screw mandrel can not be effectively controlled simultaneously, easily causes the rigging error of screw mandrel, to later process, leaves hidden danger of quality; Along with the increase year by year of plant equipment output, if do not accelerated, enhance productivity, will restrict the lifting of overall throughput.
Current bolt tightening generally has following two kinds of patterns, and a kind of is that pneumatic impact spanner is tightened, and this structural shape is simpler, can not reach leading screw anti-rotation and torque precision requirement accurately effectively.
Another kind of pattern is conventional bolt screwing machine: mainly common device for screwing up, master control cabinet, hanging rail system and equilibratory suspension etc., consist of, although this equipment operates without many people when tightening device, but because it cannot guarantee in nut rotary course, bolt is not followed its rotation, thereby make bolt tighten quality and efficiency is very low, and then affected production efficiency.
Summary of the invention
The problem existing for above-mentioned prior art, the utility model provides a kind of anti-turn bolt device for screwing up, without many people's operations, reduces human cost, guarantees that bolt does not rotate, thereby improve quality and the efficiency of bolt tightening in fastening nut process.
To achieve these goals, the technical solution adopted in the utility model is: this anti-turn bolt device for screwing up, comprise output shaft, output shaft Connection Block, push rod, outer sleeve, inner sleeve and spring I, described output shaft is quill shaft, and one end of output shaft is fixedly connected with output shaft Connection Block; Described outer sleeve is enclosed within on output shaft and can follows output shaft synchronous rotation; Described push rod is through output shaft, and the outer circumference surface of push rod is provided with axial sliding recess, and inner sleeve is contained on sliding recess; Described spring I is enclosed within on push rod, and the two ends of spring I contact with the other end of inner sleeve and output shaft respectively.
Further, also comprise spring II, the outer circumference surface of described output shaft is provided with axial sliding tray, and outer sleeve is contained on sliding tray; Described spring II is enclosed within on output shaft, and the two ends of spring II contact with output shaft Connection Block with outer sleeve respectively.
Compared with prior art, the mode that the utility model combines by inner sleeve, push rod and outer sleeve, in bolt head being stuck in to inner sleeve when tightening machine is started working, prevent its rotation, outer sleeve drives nut rotation to tighten operation, so just can effectively improve bolt tightening quality and efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, output shaft, 2, output shaft Connection Block, 3, push rod, 4, outer sleeve, 5, inner sleeve, 6, spring I, 7, spring II.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, the utility model comprises output shaft 1, output shaft Connection Block 2, push rod 3, outer sleeve 4, inner sleeve 5 and spring I 6, and described output shaft 1 is quill shaft, and one end of output shaft 1 is fixedly connected with output shaft Connection Block 2; Described outer sleeve 4 is enclosed within on output shaft 1 and can follows output shaft 1 synchronous rotary; Described push rod 3 is through output shaft 1, and the outer circumference surface of push rod 3 is provided with axial sliding recess, and inner sleeve 5 is contained on sliding recess; Described spring I 6 is enclosed within on push rod 3, and the two ends of spring I 6 contact with the other end of output shaft 1 with inner sleeve 5 respectively.
Outer sleeve 4 can be to be fixedly connected with output shaft 1, can be also to comprise spring II 7, and the outer circumference surface of described output shaft 1 is provided with axial sliding tray, and outer sleeve 4 is contained on sliding tray; Described spring II 7 is enclosed within on output shaft 1, and the two ends of spring II 7 contact with output shaft Connection Block 2 with outer sleeve 4 respectively; A kind of mode preferably, this mode makes the outer sleeve 4 can axially-movable on output shaft 1, can stretch, thereby guaranteed can mutually not push and be damaged between outer sleeve 4 and equipment when outer sleeve 4 is encountered the required equipment of tightening by nut screwing clamping.
Before work, first output shaft Connection Block 2 of the present utility model is connected with drive unit, push rod 3 is fixed on support, and while carrying out bolt tightening, outer sleeve 4 rotations, recognize cap function because tightening machine has, automatically so outer sleeve 4 is easy to and is tightened in nut sleeve; At this moment inner sleeve 5 may also not have to put with square toes or the wabbler of bolt, but because inner sleeve 5 can stretch, so at this moment can not affect outer sleeve 4, does not tighten; Under driving at outer sleeve 4, after nut rotation, can drive bolt to rotate, at this moment, bolt head will be easy to be put by inner sleeve 5; Because inner sleeve 5 is fixed, can not rotate, so once after itself and bolt head put, bolt also just can not rotate again, so plays the effect of bolt anti-rotation.
