Abstract
A drill-type electric tool is composed of a mainshaft, an integral sleeve pipe-shaped front casing with spiral thread on its external surface for matching with a nut consisting of two halves, a punching-drilling switching mechanism, and a regulating mechanism for the output torque of mainshaft. Its advantages are high mechanical strength, high axiality and high running stability.
Description
Technical field
The utility model relates to a kind of drill type electric tool.
Background technology
In the prior art, drill type electric tool comprises main shaft at least, case member before canular, drill switching mechanism, the outputting torsion governor motion of main shaft, the external peripheral surface of case member is provided with screw thread before described, nut sleeve also is threaded with it on the case member before described, the leading section of case member is provided with the preceding case member second end protuberance that radially becomes big before described, the rearward end of case member is provided with the preceding case member first end protuberance that radially becomes big before described, because the two ends of preceding case member all are radially to become big shape, the case member middle part was more carefully located before nut can not directly be enclosed within, therefore case member is made up of two discrete parts before, and these two parts are more carefully located butt joint at the middle part.But because preceding case member is two body structures, the mechanical strength variation of case member before therefore causing, the axiality of preceding case member is variation also, and the output transmission is not steady.
Summary of the invention
The object of the present invention is to provide a kind of both made before case member be structure as a whole, can make the go forward drill type electric tool at case member middle part of nut sleeve again.
Technical scheme of the present invention is: a kind of drill type electric tool, at least comprise main shaft [8], case member before canular, drill switching mechanism, the outputting torsion governor motion of main shaft, the outputting torsion governor motion of described main shaft comprises torsion adjusting cover, torque spring, bracing ring, support column, the external peripheral surface of case member is provided with screw thread before described, nut sleeve also is threaded with it on the case member before described, described torsion is regulated cover and is connected with nut, torque spring is enclosed within on the preceding case member, the both ends of torque spring withstand on respectively and reach on the bracing ring on the nut, the leading section of case member is provided with the preceding case member second end protuberance that radially becomes big before described, the rearward end of case member is provided with the preceding case member first end protuberance that radially becomes big before described, case member is structure as a whole before described, and described nut is by first half-nut, second half-nut involutes.
The present invention compared with prior art has following advantage:
Before two half-nuts can directly be placed on the case member and do not need in the past the end of case member to be inserted in, therefore before case member can be structure as a whole, its mechanical strength height, axiality height, machine driving is steady.

The specific embodiment
Referring to accompanying drawing, a kind of drill type electric tool, at least comprise main shaft 8, case member 17 before canular, drill switching mechanism, the outputting torsion governor motion of main shaft, the external peripheral surface of case member 17 is provided with screw thread before described, nut sleeve also is threaded with it on the case member 17 before described, the leading section of case member 17 is provided with the preceding case member second end protuberance 19 that radially becomes big before described, the rearward end of case member 17 is provided with the preceding case member first end protuberance 18 that radially becomes big before described, case member 17 is structure as a whole before described, and described nut is by first half-nut 6, second half-nut 14 involutes.In the accompanying drawing 2, drill switching mechanism comprises rotating impact adjusting cover 11, regulate the rotating impact shift fork 9 that cover 11 keys are connected with impact, the impact regulating sleeve 10 that is connected with impact shift fork 9, can be along the axially movable stroke adjustment sheet 7 of the direction of axis line of main shaft 8, with spring 4 contacted moved end teeth 15, a quiet end tooth 16, when rotation impact adjusting covers 11, impacting shift fork 9 rotates synchronously with impact adjusting cover 11, driving impact regulating sleeve 10 rotates synchronously, make the inclined-plane 13 promotion stroke adjustment sheets 7 that impact on the regulating sleeve 10 move axially, thereby make moved end tooth 15 can overcome the elastic force of spring 4 and move axially, when moved end tooth 15 contacts with quiet end tooth 16, the present invention is in the impact duty, and main shaft constantly axially back and forth and rotatablely move; When moved end tooth 15 was separated with quiet end tooth 16, the present invention was in the duty of the brill of rotation, and 8 on main shaft rotates.
The outputting torsion governor motion of main shaft comprise rotating torsion regulate cover 12, with torsion regulate first half-nut 6 that cover 12 is connected by key and second half-nut 14, an end be pressed in torque spring 5 on first half-nut 6 and second half-nut, 14 left sides, torque spring 5 the other end roof pressure can axially movable bracing ring 3, bracing ring 3 roof pressures can axially movable support column 2, and support column 2 contacted internal tooths 1.When the adjusting of rotation torsion covers 12, driving two half-nuts rotates synchronously, make half-nut move axially along preceding case member 17, adjusting torque spring 5 acts on the pressure on the bracing ring 3, make the adjustable in pressure that contacts of support column 2 and internal tooth 1, thereby make the maximum outputting torsion of driven by motor main shaft 8 to regulate.
