Abstract
The utility model discloses a novel electric hammer clutch device which comprises an air cylinder rotating sleeve. A clutch is connected with the air cylinder rotating sleeve through a flat key, wherein the vertical position of the clutch is adjustable. Moreover, the clutch is in contact with a large bevel gear through a slope. A pressing spring is arranged under the clutch. The utility model has the advantages of reasonable structure and adjustable moment of the clutch. In addition, the utility model ensures operators' safety and increases the service life of an electric hammer.
Description
Technical field:
The utility model relates to a kind of electric hammer clutch device.
Background technique:
Electric hammer is widely used in the usefulness of holing on the brittle materials such as brick, stone, concrete.When these material internals have hole, when in the concrete reinforcing bar being arranged, in boring procedure, drill bit is easy to be stuck, and at this moment will produce the very big moment of reaction, and operator's hand is sprained.As if operator's operation aloft, be easy to cause the falling accident of personnel and electric hammer.Though safety installations (slip clutch) has been designed in electric hammer inside, the moment of this clutch is uncontrollable.This clutch device is often transferred in maximum torque when dispatching from the factory, and makes slipping torque bigger, is not easy to skid.If gripping is not tight in using, unless you give your whole attention to it, very easily have an accident.Original friction plate clutch also has a very big shortcoming, and after cltuch slipping, moment will descend, and after skidding several times, clutch makes transmission failure with ineffective, and electric hammer will not rotate, and can not use.
Summary of the invention:
It is a kind of rational in infrastructure that the purpose of this utility model is to provide, the novel electric hammer clutch device that clutch torque is adjustable.
Technical solution of the present utility model is:
A kind of novel electric hammer clutch device has the cylinder pivoted housing, it is characterized in that: clutch is by flat key and cylinder pivoted housing that upper-lower position is adjustable to be connected, and clutch contacts by the inclined-plane with bevel gear wheel, clutch below dress stage clip.
The utility model is rational in infrastructure, and clutch torque is adjustable, guarantees operator's safety, improves the working life of electric hammer.
Description of drawings:
The utility model is described in further detail below in conjunction with drawings and Examples.
Accompanying drawing is an embodiment's of the utility model a configuration diagram.
Embodiment:
A kind of novel electric hammer clutch device has the cylinder pivoted housing 1 of electric hammer itself, clutch 2 to be by flat key 3 and cylinder pivoted housing 1 that upper-lower position is adjustable to be connected, and clutch 2 contacts by inclined-plane 5 with bevel gear wheel 4, clutch 2 belows dress stage clip 6.
Working principle of the present utility model is: when clutch moves up and down, the length of inclined-plane engagement can change, mesh long more, the moment of transmitting is big more, otherwise, mesh shortly more, the moment of transmission is more little, so change the size that length of action will change carry-over moment, thereby change the moment that bevel gear wheel passes to clutch and cylinder pivoted housing.If when in the concrete of reinforcing bar is arranged, holing, can adjust clutch distance up and down to change the size of slipping torque according to the size of drill bit, make it can keep normal boring.When drill bit was blocked by reinforcing bar, its moment can surpass the moment of normal boring, skidded immediately between clutch and the bevel gear wheel, and this moment, bevel gear wheel rotated.Clutch and cylinder pivoted housing and drill bit do not rotate, and guarantee operator's safety.Should take out and hit drill bit this moment, eliminates the drill-pipe-sticking-head fault, and slipping torque still maintains original state, can continue boring.
