Detailed description of the invention
Preferred embodiment of the present utility model is provided, to describe the technical solution of the utility model in detail below in conjunction with accompanying drawing.
Fig. 4 is the utility model for the automatic screwing device that tights a bolt for original state schematic diagram during horizontal layout.Fig. 5 is that the utility model automatic screwing device is for quick condition schematic diagram during horizontal layout.Fig. 6 is the enlarged drawing of part A in Fig. 4.
As Figure 4-Figure 6, the utility model automatic screwing device comprises bearing 10, tightens extension rod 20 and tighten sleeve 30.Herein, bearing 10, tighten extension rod 20 and tighten sleeve 30 and be axially connected to form an entirety successively, tighten and be preferably bearing between extension rod 20 and bearing 10 and connect, tighten extension rod 20 and tighten between sleeve 30 and be preferably pinned connection.
Meanwhile, described automatic screwing device also comprises guiding relocation mechanism, and described guiding relocation mechanism comprises elastomeric element 41.Elastomeric element 41 is set in be tightened on extension rod 20, and one end 411 of elastomeric element 41 is fixed on the junction of tightening extension rod 20 and bearing 10 by the first isolated part 43, and the other end 412 of elastomeric element 41 is arranged on by the second isolated part 42 and tightens on extension rod 20 near tightening sleeve 30 place, and by elastomeric element 41 to tightening sleeve 30 and tightening the end that extension rod 20 is connected and be applied with thrust, namely as shown in Figure 5 elastomeric element 41 along F direction applied thrust.
Herein, elastomeric element 41 is preferably a spring.First isolated part 43 is preferably the first spacer, one end (i.e. one end 431 of the first isolated part 43) of described first spacer connects one end (i.e. one end 411 of elastomeric element 41) of described spring, and the other end (i.e. the other end 432 of the first isolated part 43) of described first spacer is fixed on and tightens between extension rod 20 and bearing 10.
Further, the first spacer described herein (i.e. the first isolated part 43) is in T-shape.Like this, described first separation sleeve just can be fixed on by the mode of elastic compression and tighten between extension rod 20 and bearing 10.
In like manner, second isolated part 42 is preferably the second spacer herein, one end (i.e. one end 421 of the second isolated part 42) of described second spacer connects the other end (i.e. the other end 412 of elastomeric element 41) of described spring, and the other end (i.e. the other end 422 of the second isolated part 42) of described second spacer props up tightens sleeve 30 and the rear end face 31 tightened extension rod 20 and be connected.
Further, the second spacer described herein (i.e. the second isolated part 42) is in " L " type.Like this, described second separation sleeve is on the one hand for the other end (i.e. the other end 412 of elastomeric element 41) of the described spring that is locked, on the other hand for propping up the rear end face 31 tightening sleeve 30, to apply power to tightening sleeve 30, make it restore to level, ensure that the center line tightening sleeve 30 aligns with the center line tightening extension rod.Here; the thrust of described spring (i.e. elastomeric element 41) to described first spacer (i.e. the first isolated part 43) and described second spacer (the second isolated part 42) is more than or equal to 5N, and described first spacer and described second spacer can play the effect effectively protecting spring.
Based on the automatic screwing device of said structure, as shown in Figure 5, when gravity cause tighten sleeve deflection time, because the rear end face 31 tightening sleeve 30 swings the described spring of compression (i.e. elastomeric element 41), now described spring can apply the thrust along F direction (as shown in Figure 5) to the rear end face 31 tightening sleeve 30, make automatic screwing device automatically righting tighten sleeve 30, thus allow it realize self-return (original state as shown in Figure 4).
In sum, the utility model automatic screwing device is by adding guiding floating structure, automatic tightening instrument is made to achieve the layout of any direction, as vertical, horizontal or tilting, all can ensure that automatic screwing device keeps the direction of tightening sleeve, effectively extend the scope of application of automatic screwing device, improve the success rate of recognizing cap, improve efficiency of assembling.
