The rotary motor is connected with the screwdriver bit by a pneumatic cylinder, a screwdriver outlet is formed in the left end of the body, the screwdriver bit penetrates the screwdriver outlet to be connected with the pneumatic cylinder, the pneumatic cylinder is connected with the screwdriver bit by a coupling, and a torque sensor is arranged on an output shaft of the rotary motor. Torque can be detected in advance, so that damage to the structure of the motor due to excessively high torsion can be prevented. Besides, the screwdriver has electric and manual bolt tightening functions, and light can be provided when the screwdriver works, so that requirements of certain special environments can be met. The screwdriver has the advantages of simple structure, easiness in manufacture, portability, practicality and high efficiency.
Description
Technical field
The utility model relates to field of power tools, particularly a kind of screwdriver with self-protection function.
Background technology
Along with social development; the use of screwdriver becomes more and more ordinary; along with continuous use screwdriver is easy to due to the damage that is subject to excessive torsion and causes self structure; and due to the existence of some particular surroundings; in the time of work, be easy to be subject to the impact of light and electric power, just seem particularly important so design a kind of screwdriver with self-protection function.
Chinese invention patent discloses a kind of electric screw driver No. CN103264367A, its structure comprises handle casing, handle cap, HVDC motor and control circuit, slow down to become and turn round case, main shaft, connecting axle and elbow assembly, HVDC motor and control circuit, slow down to become and turn round case, main shaft is all installed in handle casing, main shaft passes the torsion of handle cap output electric screw driver, elbow assembly comprises elbow seat and lid thereof, output shaft and a pair of tooth that revolves, one of them revolves tooth device on output shaft, another revolves tooth device at connecting axle front end, output shaft and connecting axle are fixed a pair of tooth that revolves are installed in elbow seat by bearing respectively, connecting axle rear end connects main shaft and the concentricity axle of main shaft.This invention has good transmission performance, but damage of self structure can occur to cause because torque is excessive in actual use for it.
Summary of the invention
The utility model technical issues that need to address are the excessive damages that cause motor of torsion that prevent due to rotation; A kind of screwdriver with self-protection function is provided.
For solving above-mentioned technical problem, structure of the present utility model comprises fuselage, cutter head and electric rotating machine, electric rotating machine is connected with cutter head by pneumatic linear actuator, the left end of fuselage has out the edge of a knife, cutter head passes out the edge of a knife and is connected with pneumatic linear actuator, pneumatic linear actuator is connected with cutter head by shaft coupling, and the shaft of electric rotating machine is provided with torque sensor.
Further: the left end of described fuselage is also provided with bulb.
Further again: the relative both sides of described fuselage are also provided with lever, and lever is rotationally connected by bearing pin and fuselage.
Adopt after said structure, the utility model not only can be by detecting moment of torsion in advance, prevents that motor from causing the damage of self structure because torsion is excessive; And there is the function of electronic and manual elasticity bolt simultaneously, when work, can provide light to tackle the needs of some particular surroundings; And that the design also has advantages of is simple in structure, be easy to manufacture, easy to carry, practicality and high efficiency.
Brief description of the drawings
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
In figure: 1 is fuselage, 2 is electric rotating machine, and 3 is cutter head, and 4 for going out the edge of a knife, and 5 is pneumatic linear actuator, and 6 is lever, and 7 is torque sensor, and 8 is shaft coupling, and 9 is bulb
Detailed description of the invention
A kind of screwdriver with self-protection function as shown in Figure 1; structure comprises fuselage 1, cutter head 3 and electric rotating machine 2; it is characterized in that: electric rotating machine 2 is connected with cutter head 3 by pneumatic linear actuator 5; the left end of fuselage 1 has out the edge of a knife 4; cutter head 3 passes out the edge of a knife 4 and is connected with pneumatic linear actuator 5; pneumatic linear actuator 5 is connected with cutter head 4 by shaft coupling 8, and the shaft of electric rotating machine 2 is provided with torque sensor 7.Along with social development; the use of screwdriver becomes more and more ordinary; along with continuous use screwdriver is easy to due to the damage that is subject to excessive torsion and causes self structure; and due to the existence of some particular surroundings; in the time of work, be easy to be subject to the impact of light and electric power, so the utility model has designed a kind of screwdriver with self-protection function.The design rotates with pneumatic linear actuator 5 by controlling electric rotating machine 2, cutter head 3 together rotates with pneumatic linear actuator 5 under the effect of shaft coupling 8, thereby play the effect of elasticity bolt, in the time that electric rotating machine 2 is subject to compared with high pulling torque, be positioned at torque sensor on electric rotating machine 27 can test to data pass to controller, thereby make controller control pneumatic linear actuator 5 depart from shaft coupling 8, make the unloaded rotation of electric rotating machine 2, thereby play the effect that prevents that motor from burning out.Shrink cutter head 3 retractions are gone out in the edge of a knife 4 thereby can control pneumatic linear actuator 5 in the time going out operation, play and reduce space, portable effect.
The left end of fuselage 1 as shown in the figure is also provided with bulb 9, and the relative both sides of described fuselage 1 are also provided with lever 6, and lever 6 is rotationally connected by bearing pin and fuselage 1.Sometimes due to the impact of the operating environment of going out, in the time that working environment is darker, can illuminate according to the left end of fuselage 1 of the left end that is arranged on fuselage 1, be convenient to work; In the time that residing environment does not have power supply, can utilize to be arranged on fuselage 1 both sides lever 6 and to carry out manual degree of tightness, very convenient laborsaving.
The utility model not only can be by detecting moment of torsion in advance in sum, prevents that motor from causing the damage of self structure because torsion is excessive; And there is the function of electronic and manual elasticity bolt simultaneously, when work, can provide light to tackle the needs of some particular surroundings; And that the design also has advantages of is simple in structure, be easy to manufacture, easy to carry, practicality and high efficiency.
