Embodiment
A kind of drawbench of dismounting axis of 1 pair of the utility model is described in further detail below in conjunction with the accompanying drawings.
A kind of drawbench of the dismounting axis of the utility model, including, driving screw 1 and sleeve 2, the driving screw 1 are arranged in
2 center of sleeve, the driving screw 1 are flexibly connected with 2 reciprocating motion type of sleeve, and the right end of the driving screw 1 is with needing
The axis 5 to be dismantled is detachable to be fixedly connected, and the right end of the sleeve 2 and the axis base 6 of the axis 5 for needing to dismantle offset.
In this way, the right end of the driving screw 1 is used to connect the axis 5 for needing to dismantle, the sleeve 2 plays the driving screw 1 fixed
The effect of position.The right end of the sleeve 2 and the axis base 6 are offseted, the axis base 6 can be the axis for needing to dismantle
The blind hole where babinet or the axis 5 for needing to dismantle where 5, the sleeve 2 play the fixed effect of support,
The driving screw 1 is flexibly connected with 2 reciprocating motion type of sleeve, during working status, the sleeve 2 and 6 phase of axis base
Constant to holding position, the driving screw 1 is moved out relative to the sleeve 2, drives the axis 5 for needing to dismantle to outward transport
Dynamic, it is achieved thereby that the dismantlement work of the axis 5 for needing to dismantle, dismounting is simple, improves removal efficiency height, avoids use
The damage caused by part and the axis base during axis that the hammering method dismounting needs are dismantled.In terms of existing technologies,
A kind of drawbench of the dismounting axis of the utility model have the advantages that it is lower, can be by the axis in complicated body structure or in blind hole from narrow and small
Space in take out, and the axis base of axis that the other parts and needs not injured in babinet are dismantled, dismounting is simple, dismounting
Efficient, applicability is wide.
A kind of drawbench of dismounting axis of the utility model, please refers to Fig.1, on the basis of previously described technical solution
On, it can also be：The right end of the driving screw 1 is threadedly coupled with the axis 5 for needing to dismantle.In this way, needs described first are torn open
The axis 5 unloaded is with female, and the external screw thread of the driving screw 1 is identical with the internal thread of the axis 5 for needing to dismantle, described
Driving screw 1 is threadedly coupled with the axis 5 for needing to dismantle, and this connection mode is simple in structure, and connection is reliable, convenient disassembly.
A kind of drawbench of dismounting axis of the utility model, please refers to Fig.1, on the basis of previously described technical solution
On, it can also be：The right-end openings of the sleeve 2, the right end of the sleeve 2 are sheathed on one end of the axis 5 for needing to dismantle
Outside, the right end of the sleeve 2 and the outer wall of the axis base 6 of the axis for needing to dismantle offset.In this way, described need what is dismantled
Axis 5 is normally in babinet or at blind hole, that is, the axis base can be babinet or blind hole, the right side of the sleeve 2
End cap is arranged on the outside of one end of the axis 5 for needing to dismantle, and the sleeve 2 is supported on the outer wall of the axis base, when described
When driving screw 1 is moved out relative to the sleeve 2, the left end of axis 5 to the sleeve 2 for needing to dismantle is driven to move,
So as to fulfill the dismounting of the axis 5 for needing to dismantle, such design structure is simple, and the sleeve 2 can be kept in working status
Stablize, it is easy to disassemble.On the basis of previously described technical solution, it is further preferred that：The sleeve 2, which is equipped with, to be lengthened
Cylinder, the left end of the expansion link with the right end of the sleeve 2 is detachable is fixedly connected, the right end of the expansion link and the axis
The outer wall of base 6 offsets.In this way, be because dismantle it is described need dismantle axis 5 when, in order to make its completely disengage the babinet or
The blind hole, i.e., described axis base, the depth of the sleeve 2 should be greater than or equal to the length of the axis for needing to dismantle, institute
It is the length for increasing the sleeve 2 to state expansion link, makes the expansion link of different model, when the axis mistake for needing to dismantle
When long, increase the length of the sleeve 2 by the expansion link, it is wider so as to fulfill the dismounting of the axis of different length, applicability.
A kind of drawbench of dismounting axis of the utility model, please refers to Fig.1, on the basis of previously described technical solution
On, it can also be：The left end of the driving screw 1 is equipped with driving device, and the driving device and the left end of the driving screw 1 are removable
