The utility model content
The technical problem that the utility model will solve is in order to overcome the defective that the prior art beveler can not use in abominable working environment such as inflammable and explosive grade, a kind of hand-held pneumatic beveler to be provided.
The utility model solves above-mentioned technical problem through following technical proposals: a kind of hand-held pneumatic beveler, and its characteristics are that it comprises: the body of a hollow, a governor motion and a guide plate, wherein:
In said body, be provided with the cutter hub that output shaft and that an air motor, is provided with a pair of deceleration bevel gear has a bite, said air motor is through the said output shaft of said deceleration bevel gear driving, and said cutter hub is connected in said output shaft lower end;
Said governor motion is connected in the lower end of said body;
Said guide plate is one " L " shape L-square, and the straight plate in one side of said " L " shape L-square is fixedly connected with the lower end of said governor motion through screw.Like this, form the drift angle of " L " shape L-square and the bite relative position of output shaft lower end and change, to realize the variation of chamfer angle.
Preferably, said air motor is a pneumatic vane motor.
Preferably, said governor motion is followed successively by a coupling sleeve, adjustment eccentric wheel and a regulating sleeve from top to bottom, and said coupling sleeve is connected in the bottom of said body through screw, and said regulating sleeve is connected with said coupling sleeve through screw.
Preferably, the eccentric scale of said adjustment is 0-8mm, and the scale on the said regulating sleeve is 15 °-45 °.
In the utility model, but above-mentioned optimum condition combination in any on the basis that meets this area general knowledge promptly gets each preferred embodiment of the utility model.
The positive progressive effect of the utility model is:
One, the utility model substitutes the power single phase miniature motor of beveler with vane air motor; Realized the requirement under bad working environment, used, and all can operate as normal under unfavorable conditions such as inflammable, explosive, high temperature, vibration, humidity, dust.
Two, the adjusting range of chamfer dimesion becomes big, and the chamfering width is adjusted into 0-8mm by 0-3mm.
Three, guide plate becomes integral type by two, when the adjusting chamfer angle is 15 °-45 °, becomes more intuitively feasible.
Four, the utlity model has higher starting torque, can directly be with the load starting, start, stop all rapid.Overload protective function is arranged, can not break down because of overload.Handiness, Maintenance and Repair are easy.
Description of drawings
Fig. 1 is the structural representation of the utility model preferred embodiment.
Fig. 2 is the structural representation of governor motion in the utility model preferred embodiment.
The specific embodiment
Provide the utility model preferred embodiment below in conjunction with accompanying drawing, to specify the technical scheme of the utility model.
As depicted in figs. 1 and 2, it comprises the utility model hand-held pneumatic beveler: the body 1 of a hollow, a governor motion and a guide plate 6.Wherein, in body 1, be provided with the air motor of an output torque, be preferably a pneumatic vane motor 2.Pneumatic vane motor 2 is as actuating unit, as transmission mechanism, output shaft 4 passed in torque through a pair of deceleration bevel gear 3.Cutter hub 5 is connected in a threaded manner to output shaft 4 lower ends, and has a bite 51 on the cutter hub 5, and output shaft 4 drives cutter hub 5 and makes bite 51 rotary cuttings.In addition, guide plate 6 is one " L " shape L-square, and said " L " shape L-square is fixed on the adjustable plate 61 through screw 62, through realizing the variation of chamfer angle with the variation of bite 51 relative positions of output shaft lower end.
In the lower end of body 1 governor motion is housed.Said governor motion is followed successively by a coupling sleeve 8, an adjustment eccentric wheel 9 and a regulating sleeve 7 from top to bottom, and coupling sleeve 8 is connected in the lower end of body 1 through screw 81, and regulating sleeve 7 is connected with coupling sleeve 8 through two screws 71.The scale of expression width is 0-8mm on the adjustment eccentric wheel 9, and the scale of expression angle is 15 °-45 ° on the regulating sleeve 7.
Before using,, make the center of off-centring output shaft 4 of whole governor motion through adjustment eccentric wheel 9 and regulating sleeve 7 and the circumferential relative position in coupling sleeve 8 bottoms.Its method that adopts is two screws 71 that unclamp on the regulating sleeve 7, according to the groove of 0-8mm on the adjustment eccentric wheel 9, regulating sleeve 7 rotated to required chamfer dimesion after, tighten two screws 71, can realize that width is the chamfering of 0-8mm.The method of regulating chamfer angle is to unclamp screw 72, according to 15 ° on the regulating sleeve 7-45 ° angle groove, rotates guide plate 6 then and is adjusted to required chamfer angle, tightens screw 72 again, can realize that just chamfer angle is 15 °-45 °.After adjusting chamfering required width and angle, unclamp screw 81, promptly adjust the circumferential relative position of whole governor motion and body 1 bottom, thereby governor motion is adjusted to the direction that grips of favourable cutting.Like this, both can use this hand-held pneumatic beveler to process after accomplishing above-mentioned adjustment process.
