Abstract
The utility model relates to a pneumatic screwdriver, which comprises a pneumatic tool and a screwdriver bit member which is connected to the tool. The screwdriver bit member is provided with an engaged end head and a straight rod part; the pneumatic tool is provided with a gas-entering end through which gas pressure pipe members are connected and a push switch which can control the high-speed gas in the gas pressure pipe members to enter the tool to cause the screwdriver bit to operate; the straight rod part of the screwdriver bit member is transversely provided with radial penetrating space, and the penetrating space can also be penetrated and arranged slantways. The utility model can absorb instant impact force in position-reaching locking through the arrangement of the penetrating space in time so that the engaged end head of the screwdriver bit and a head engaging position of a screw are not deformed or damaged in pneumatic high-speed locking, which conforms to operation requirements.
Description
The utility model relates to a kind of pneumatic screw driver.
Pneumatic screw driver, be that a kind of high efficiency laborsaving and that rotating speed is fast is locked instrument, because rotating speed can produce strong impulsive force in locking soon moment, therefore the screwdriver head element of pneumatic screw driver (being the element that engaging screw drives) adopts special spring steel more, instant impact when locking by the micro-elasticity absorption of spring steel, be suitable for the screwdriver head element that pneumatic tool uses to provide, this screwdriver head element must be bestowed the heat treatment process of sclerosis, as everyone knows, even also can cause heat treatment result's difference at standardized heat treatment operation because of all factors, make the coefficient of elasticity of screwdriver head element produce error, when the material of the screw element that is applied or processing error factors are assembled in addition, its instant impact promptly causes screw head engagement position to be deformed into damage easily, screw element after the locking can't be revolved for the screwdriver head engagement again to move back, therefore known pneumatic screw driver is to the high speed instant impact of position locking the time, and disappearances such as the distortion that causes screw head engagement position easily or damage are arranged.
Main purpose of the present utility model is to provide a kind of pneumatic screw driver, and the instant impact when in good time being absorbed in position locking makes the engagement termination of screwdriver head and screw head engagement position a unlikely distortion or a damage when pneumatic high speed locking.
For achieving the above object, solution of the present utility model is:
A kind of pneumatic screw driver, comprise pneumatic tool and knot be located on this instrument can pneumatic running the screwdriver head element, this screwdriver head element has engagement termination and straight-bar portion, the high-speed gas that this pneumatic tool then is provided with the air inlet end that is connected the air pressure pipe fitting and can controls pneumatic tube spare enters the pressing switch that instrument makes the screwdriver head running, and wherein: the straight-bar portion of screwdriver head element is horizontally set with perforative space radially; This perforative space also can be the oblique setting that runs through.
After adopting said structure, pneumatic screw driver of the present utility model is provided with perforative space in the straight-bar portion of screwdriver head element, can revise the variance factor of pneuma-lock, make that to lock at a high speed operation more perfect, the elastic reaction in this space, the part instant impact in the time of can in good time absorbing position locking, thus lower powerful impact of the moment that is rotated in place locking at a high speed, make engagement termination and the screw head engagement position unlikely distortion or the damage when pneumatic high speed is locked of screwdriver head, and meet job requirements.
Below in conjunction with drawings and Examples, the utility model is further described.
Fig. 1 is a three-dimensional exploded view of the present utility model;
Fig. 2 is the plane of the utility model screwdriver head;
Fig. 3 is the partial cutaway diagrammatic sketch of the utility model screwdriver head;
Fig. 4 is that the utility model screwdriver head changes the partial cutaway diagrammatic sketch of implementing;
Fig. 5 is the partial cutaway diagrammatic sketch one of another embodiment of the utility model;
Fig. 6 is the partial cutaway diagrammatic sketch two of another embodiment of the utility model.
See also shown in Figure 1ly, the utility model is made up of the screwdriver head element 2 that pneumatic tool 1 and knot are located on this instrument.This pneumatic tool 1 has an air inlet end 11 at least, one pressing switch 12 and a knot are established portion 13, air inlet end 11 air feed pressure pipe parts are connected so that the air inlet source of pneumatic tool 1 to be provided, the air inlet source of gases at high pressure (admission pressure that generally has 7Kg/cm2) is controlled by pressing switch 12, gases at high pressure flow into tool interior and drive knot and establish portion 13 rotation at a high speed when opening pressing switch 12, knot is established 13 straight-bar portion 21 knots for screwdriver head element 2 of portion and is established, the 22 cross ditches (or a word ditch) with the screw element head in the engagement termination of screwdriver head element 2 mesh, and pneumatic screw driver are arranged to screw element turn effect.
As shown in Figures 2 and 3, the utility model screwdriver head element 2 is to make with the spring steel, have non-round shape straight-bar portion 21 and can with the engagement termination 22 of screw element head engagement, wherein, straight-bar portion 21 is horizontally set with one and runs through space 211, this perforative space 211 provides the elastic reaction space of steel, instant impact in the time of can in good time absorbing at a high speed to position locking, in other words, instant impact during locking makes screw element and screwdriver head element 2 mesh the position not impact of reason brute force and distortion or damage because of the elastic reaction of perforative space 211 reduces.Fig. 4 shows alternate embodiment figure of the present utility model, its perforative space 212 is the oblique setting that runs through, this oblique torsion direction of closing in instant impact that runs through has better elastic reaction with attenuating powerful impact of moment, and is applicable to the high torsion pneumatic screw driver instrument of high poundage locking.
Fig. 5 and Fig. 6 show another embodiment of the utility model screwdriver head element, be that explanation the utility model is applied to the screwdriver head element 3 that two ends form engagement termination 32,33 respectively, the straight-bar portion 31 of this screwdriver head element 3 is provided with perforative space 311 or closes the oblique perforative space 312 that uses in high poundage, high torsion, instant impact when lowering with the elastic reaction that this space is provided, and then the performance engagement unlikely distortion in position or damage and meet effect such as job requirements at a high speed to position locking.
Claims (2)
1, a kind of pneumatic screw driver, comprise pneumatic tool and knot be located on this instrument can pneumatic running the screwdriver head element, this screwdriver head element has engagement termination and straight-bar portion, the high-speed gas that this pneumatic tool then is provided with the air inlet end that is connected the air pressure pipe fitting and can controls pneumatic tube spare enters the pressing switch that instrument makes the screwdriver head running, and it is characterized in that: the straight-bar portion of screwdriver head element is horizontally set with perforative space radially.
