A kind of small screws automatic screwing device
The utility model relates to mechanical equipment technical field more particularly to a kind of small screws automatic screwing devices.
Traditional screw manual assembly working efficiency is low, worker large labor intensity, product assembly quality are unstable, with
, there is semi-automatic screw assembly machine, such as hand-held screw-driving machine, alleviates work to a certain extent in the demand of society and production
It the labor intensity of people and improves work efficiency, but still needs artificial intervention, the degree of automation is not high, smaller for model
Small screws will appear many ask in assembling process because its is small in size.
Utility model content
In view of the above technical problems, the utility model provides a kind of small screws automatic screwing device, reasonable in design
Simply, size is small, high-efficient, at low cost, and the small screws especially suitable for complicated station are assembled.
To realize the above-mentioned technical purpose, a kind of the technical solution adopted in the utility model are as follows: small screws automatic tightening dress
It sets, including is made of cylinder, first shell, motor, sensor, tightening axle, second shell, screw entrance, locating clip, the gas
The upper surface of cylinder and side lower are provided with stomata, and the second shell lower side is equipped with cylindrical pipe obliquely, i.e.,
For screw entrance, the screw entrance and second shell lower side are integrally welded, and connect inside screw entrance and second shell
Logical, the lower end of the second shell is circular open, and the locating clip is generally cylindrical, which is
Cone, the cylinder are mounted in first shell by screw, and the first shell is connect by screw with second shell, institute
The piston rod end for stating cylinder is threadedly attached on the upper surface of motor housing, which is located in second shell, described
Sensor is fixed by screws on the downside surface of motor housing, and described tightening axle one end is mounted in motor by bearing,
The other end of the tightening axle is located at the top of the lower end circular open of second shell, and the locating clip is pacified by clip and screw
At the lower end circular open of second shell.
The advantageous effects of the utility model are: the small screws automatic screwing device, reasonable in design simple, ruler
Very little small, high-efficient, at low cost, the small screws especially suitable for complicated station are assembled.
Detailed description of the invention
Fig. 1 is a kind of small screws automatic screwing device structural schematic diagram.
Wherein: 1 is cylinder, and 2 be first shell, and 3 be motor, and 4 be sensor, and 5 be tightening axle, and 6 be second shell, and 7 are
Screw entrance, 8 be locating clip.
In conjunction with attached drawing, now the utility model is described in further detail.
As shown in Figure 1, a kind of small screws automatic screwing device, including by cylinder 1, first shell 2, motor 3, sensor
4, tightening axle 5, second shell 6, screw entrance 7, locating clip 8 form, and the upper surface of the cylinder 1 and side lower are provided with gas
Hole, 6 lower side of second shell are equipped with cylindrical pipe obliquely, as screw entrance 7, the screw entrance and 7 the
Two shells, 6 lower side is integrally welded, and is connected to inside screw entrance 7 and second shell 6, the lower end of the second shell 6
Portion is circular open, and the locating clip 8 is generally cylindrical, which is cone, and the cylinder 1 is logical
It crosses screw to be mounted in first shell 2, the first shell 2 is connect by screw with second shell 6, the piston of the cylinder 1
Boom end is threadedly attached on the upper surface of 3 shell of motor, which is located in second shell 6, and the sensor 4 is logical
It crosses screw to be fixed on the downside surface of 3 shell of motor, described 5 one end of tightening axle is mounted in motor 3 by bearing, this is tightened
The other end of axis 5 is located at the top of the lower end circular open of second shell 6, and the locating clip 8 is installed by clip and screw
At the lower end circular open of second shell 6.
In actual work, the rundown process for the distance controlling screw that device is declined by torque and tightening axle, when screw from
Enter at screw entrance 7 and be slipped at the lower end circular open of second shell 6, and there is locating clip 8 to position screw, makes
Screw is on locating clip 8 in the state i.e. screw-driving end for being conducive to tighten to be aligned with 5 axle center of top tightening axle, under screw
Side passes through the top that 8 hole of locating clip is located at workpiece screw hole, detects that screw is located at 5 lower section of tightening axle, cylinder through sensor 4 after
1 upper end air inlet gas inlet hole, piston moves downward for promotion, and piston rod pushes whole device to move downward, when 5 end of tightening axle and spiral shell
Tightening axle 5 rotates when nail joint is touched, and starts to screw-driving.
Preferred embodiments of the present invention above described embodiment only expresses, the description thereof is more specific and detailed,
But it should not be understood as limiting the scope of the patent of the utility model.It should be pointed out that for the common of this field
For technical staff, without departing from the inventive concept of the premise, several deformations can also be made, improves and substitutes, these are all
Belong to the protection scope of the utility model.Therefore, the scope of protection shall be subject to the appended claims for the utility model patent.
