The utility model discloses the work head vibration-proof structure of multi-functional electric saw, including work head, collar bush and push rod, collar bush is made up of axle sleeve one, axle sleeve two and the axle sleeve three being sequentially connected from top to bottom, and the outside diameter value of axle sleeve one, axle sleeve two and axle sleeve three is incremented by successively；The straight of axle sleeve one has been arranged roller bearing with it, and the top of axle sleeve one is inserted in swing rod；The bottom of axle sleeve three has a mounting hole, is inserted in mounting hole at the top of work head；Push rod is inserted in collar bush, and its bottom is connected with work head；The straight of axle sleeve two has been arranged a balance weight with it, and balance weight is by annulus sleeve and the fan-shaped bump for being arranged on annulus sleeve outer rim.Increased balance weight balances each other with the motion of saw blade on collar bush, effectively reduces vibration when saw blade cuts, and improves operating personnel's usage comfort, so as to further reduce the hand fatigue sense that operating personnel cause by vibration, improves operating efficiency.
Description
Technical field
The utility model is related to electric tool technical field, the work head vibration-proof structure of more particularly to multi-functional electric saw.
Background technology
In cutting, what the saw blade on work head did is left-right rotary pendular motion to multi-functional electric saw.Because the saw blade of electric saw does partially
The heart is moved, and can cause very big vibration, and operating personnel's feel is poor, fatiguability during long-time handheld tool, influences operating efficiency.
Utility model content
In order to solve the above technical problems, the utility model provides the work head vibration-proof structure of multi-functional electric saw, it can be with
The vibration of multifunctional saw is adjusted, balance is reached, vibration is reduced, comfortable feel degree when operating personnel operate is improved.Be up to
To above-mentioned purpose, the technical solution of the utility model is as follows：
The work head vibration-proof structure of multi-functional electric saw, including work head, collar bush and push rod；
The collar bush is made up of axle sleeve one, axle sleeve two and the axle sleeve three being sequentially connected from top to bottom, the axle sleeve one, axle
The outside diameter value of set two and axle sleeve three is incremented by successively；
The straight of the axle sleeve one has been arranged roller bearing with it, and the top of the axle sleeve one is inserted in swing rod；
The top that the bottom of the axle sleeve three has a mounting hole, the work head is inserted in the mounting hole；It is described
Push rod is inserted in the collar bush, and its bottom is connected with work head；
The straight of the axle sleeve two has been arranged a balance weight with it, and the balance weight is by annulus sleeve and is arranged on annulus set
The fan-shaped bump of cylinder outer rim.
It is further, the either flush of the top surface of the fan-shaped bump and the annulus sleeve, the fan-shaped bump
Bottom surface has a fan-shaped projection, and the fan-shaped raised interior circular diameter is equal to the outside diameter of the axle sleeve three.
It is further that the angle of the fan-shaped bump is between 110 ° -115 °.
It is further that the angle of the fan-shaped bump is 113 °.
The work head vibration-proof structure of the multi-functional electric saw provided by above-mentioned technical proposal, the utility model, on collar bush
Increased balance weight balances each other with the motion of saw blade, effectively reduces vibration when saw blade cuts, and improves operating personnel and uses and relaxes
Appropriateness, so as to further reduce the hand fatigue sense that operating personnel cause by vibration, improves operating efficiency.
Brief description of the drawings
In order to illustrate more clearly of the technical scheme in the utility model embodiment, below will be to needed for embodiment description
The accompanying drawing to be used is briefly described.
Fig. 1 is the partial sectional view of a kind of multi-functional electric saw disclosed in embodiment one；
Fig. 2 is the structural representation of the collar bush disclosed in embodiment one；
Fig. 3 is the front view of the balance weight disclosed in embodiment one；
Figure 4 and 5 are the structural representation of the balance weight disclosed in embodiment two.
Specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe.
Embodiment one
Shown in Fig. 1 is a kind of partial sectional view of multi-functional electric saw, and as can be seen from the figure the electric saw has vibration damping
Structure.Above-mentioned vibration-proof structure includes work first 1, collar bush 2 and push rod 3；Referring to Fig. 2, collar bush 2 by being sequentially connected from top to bottom
The 2a of axle sleeve one, the 2b of axle sleeve two and the 2c of axle sleeve three compositions, the outside diameter value of axle sleeve one, axle sleeve two and axle sleeve three is incremented by successively；
The straight of axle sleeve one has been arranged roller bearing 5 with it, and the top of axle sleeve one is inserted in swing rod 6；The bottom of axle sleeve three has a peace
Dress hole 2d, the top of work first 1 is inserted in mounting hole；Push rod 3 is inserted in collar bush 2, and its bottom first with work 1 is connected；Axle sleeve
Two it is straight be arranged a balance weight 4, balance weight is by annulus sleeve 4a and the fan-shaped bump for being arranged on annulus sleeve outer rim
4b is constituted, and the angle of fan-shaped bump is 113 ° (referring to Fig. 3).
The signified direction of fan-shaped bump is in opposite direction with saw blade, and balance weight balances each other with the motion of saw blade, effectively reduces
Vibration when saw blade cuts, improves operating personnel usage comfort, so as to further reduce operating personnel because vibration causes
Hand fatigue sense, improves operating efficiency.
Embodiment two
The fan-shaped bump size of balance weight depends on the quality of saw blade, when the quality of saw blade changes, balance weight
Need to change.But the length of the axle sleeve two in collar bush 2 is constant, the thickness of the annulus sleeve of balance weight can not become
Change, so can only go to change the thickness of fan-shaped bump.
Referring to Figure 4 and 5, the top surface of fan-shaped bump and the either flush of annulus sleeve, the bottom surface of fan-shaped bump has one
Fan-shaped projection 4c, fan-shaped raised interior circular diameter is equal to the outside diameter of axle sleeve three.When mounted, fan-shaped raised is interior for balance weight
Disc is fitted with the cylindrical of axle sleeve three.The fan-shaped raised quality as fan-shaped bump is supplemented so that the motion of balance weight and saw blade
Balance each other.
The foregoing description of the disclosed embodiments, enables professional and technical personnel in the field to realize or new using this practicality
Type.Various modifications to above-described embodiment will be apparent for those skilled in the art, determine herein
The General Principle of justice can in other embodiments be realized in the case where spirit or scope of the present utility model are not departed from.Cause
This, the utility model is not intended to be limited to the embodiments shown herein, and is to fit to and principles disclosed herein
The most wide scope consistent with features of novelty.
