Abstract
The utility model discloses a kind of no-welding axis and box body assembling structure, including axis body and cabinet, axis body passes through the end plate of cabinet, one piece of outer end plate is welded on the end plate of cabinet, axis body is equipped with first step and transition shoulder, wherein first step is located at the interior clamping of end plate, outer end plate noose on transition shoulder, the diameter of first step is greater than transition shoulder, axis body is interference fitted with the contact surface of cabinet, end plate and first step and axis body, outer end plate and transition shoulder, and end plate and outer end plate are welded as a whole structure on periphery.Although the utility model structure is simple, design is very ingenious, and using additional one piece of outer end plate, and increasing a transition bench makes axis body in the case where no welding, can be very good the cooperation for completing axis and cabinet, avoids because of injury caused by welding axis body.
Description
Technical field：
The utility model relates to mach fixed structure design fields, and particularly a kind of no-welding axis and cabinet fill
Distribution structure.
Background technique：
In actual production, it can encounter when box sizes are relatively large in diameter with respect to axis body, and cabinet needs and axis body cooperates again,
It under normal circumstances, is that axis is pressed into cabinet, by contact position between the intracorporal axis body diameter of case and axis body using interference fit, then
Circumference soldering is carried out in cabinet end plate and axis body junction.This mode will cause axis body and generate thermal stress in the material of weld
Area makes the exposed parts of axis under alternate load effect, is broken in this thermal stress area.
Utility model content：
Purpose of the utility model is to solve the deficiencies in the prior art, provides the no-welding axis of one kind and cabinet fills
Distribution structure.
The technical solution adopted in the utility model is：
A kind of no-welding axis and box body assembling structure, including axis body and cabinet, axis body pass through the end plate of cabinet, cabinet
One piece of outer end plate is welded on end plate, axis body is equipped with first step and transition shoulder, and wherein first step is located at card in end plate
Connect, outer end plate noose is on transition shoulder, the diameter of first step is greater than transition shoulder, axis body and cabinet, end plate and First
The contact surface of rank and axis body, outer end plate and transition shoulder is interference fitted, and end plate and outer end plate are welded as a whole on periphery
Structure.
Described one kind no-welding axis and box body assembling structure, it is characterised in that：
The end plate left wall is provided with mounting groove, the first step clamping of axis body in mounting groove.
Described one kind no-welding axis and box body assembling structure, it is characterised in that：
The two sides side wall of the first step contacts the side wall of outer end plate and the mounting groove slot bottom of end plate respectively.
Described one kind no-welding axis and box body assembling structure, it is characterised in that：
Contact corner of the transition shoulder with outer end plate, axis body rounded corner, outer end plate bevelling.
Described one kind no-welding axis and box body assembling structure, it is characterised in that：
Contact corner of the first step with end plate, axis body rounded corner, end plate bevelling.
Compared with prior art, the beneficial effects of the utility model are：
Although the utility model structure is simple, design is very ingenious, using additional one piece of outer end plate, and increases by one
A transition bench all uses chamfering form on the periphery of outer end plate and cabinet end plate, and the interference using diameter difference and hole and axis is matched
It closes, so that two end plates is synthesized an entirety, make axis body in the case where no welding, can be very good to complete matching for axis and cabinet
It closes, avoids because of injury caused by welding axis body.
Detailed description of the invention：
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the partial enlargement structure chart in the utility model Fig. 1 at A.
Specific embodiment：
With reference to the accompanying drawing, the utility model is described in further detail by embodiment：
A kind of no-welding axis and box body assembling structure, including axis body 1 and cabinet 2, axis body 1 pass through the end plate 3 of cabinet 2,
One piece of outer end plate 4 is welded on the end plate 3 of cabinet 2, axis body 1 is equipped with first step 101 and transition shoulder 102, wherein first
Step 101 is located at clamping, 4 noose of outer end plate in end plate 3, and on transition shoulder 102, the diameter of first step 101 is greater than transition bench
The contact surface mistake of rank 102, axis body 2 and cabinet 3, end plate 4 and first step 101 and axis body 2, outer end plate 5 and transition shoulder 102
It is full of cooperation, end plate 4 and outer end plate 5 are welded as a whole structure on periphery.
3 left wall of end plate is provided with mounting groove, the clamping of first step 101 of axis body 1 in mounting groove.
The two sides side wall of first step 101 contacts the side wall of outer end plate 4 and the mounting groove slot bottom of end plate 3 respectively.
The contact corner of transition shoulder 102 and outer end plate 5,2 rounded corner of axis body, 4 outer end plate bevellings.
The contact corner of first step 101 and end plate 3,1 rounded corner of axis body, 3 bevelling of end plate.
Above-described embodiment is only the preferable embodiment of the utility model, and in addition to this, the utility model can also have
Other implementations.It should be noted that without departing from the concept of this utility model, any conspicuous improvement
It should fall within the protection scope of this utility model with modification.
