Embodiment
The technical solution of the utility model is further elaborated with reference to embodiment and accompanying drawing.
Embodiment 1
A kind of Vehicular electric water pump fixing device is present embodiments provided, can by the Vehicular electric water pump fixing device
So that electric water pump is fixed on vehicle body, i.e., the present embodiment discloses the fixing device of a kind of electric water pump and vehicle body.
In the present embodiment, the Vehicular electric water pump fixing device includes：Main support, auxiliary stand, screw bolt and nut.
The section of the main support is in " several " font, i.e., including top panel, two connecting plates and two fixed plates；On described
The two ends of the width of panel are respectively fixed with connecting plate, and the other end of the connecting plate is respectively fixed with fixed plate, and makes
Obtain described two fixed plates at grade, and each parallel to the top panel；In the present embodiment, the connecting plate is in institute
Can be slightly larger than by stating the angle between top panel by 90 degree, for example, 95-105 degree can be taken, so that between two connecting plates not
It is parallel to each other, and in certain angle so that the distance between lower end of connecting plate is greater than the width of the top panel.
To be housed on the main support in electric water pump, the present embodiment, along the width side of top panel on the main support
To arc-shaped slot is offered, the arc-shaped slot runs through the top panel, and causes the left end formation screw peace of the top panel
Dress portion, its right-hand member formation hooks piece portion；And described two connecting plates are respectively formed on arc-shaped slot.
The section of the width of the auxiliary body frame is circular arc, and its circumferential one end is formed as hook, described auxiliary
The circumferential other end formation connecting portion of body frame is helped, wherein the hook is engaged with the hook piece portion, i.e., described hook is ganged up with
In the hook piece portion, the connecting portion can be fixed on the screw installation portion of the main support by screw and nut.
In the present embodiment, offered on the connecting portion and offer the second through hole on first through hole, the screw installation portion,
And by being welded with nut on the lower surface of the screw installation portion, the screw passes through first through hole and the second through hole,
Combined with the nut.
In the present embodiment, the two ends of the length direction of the fixed plate offer fixing hole, by the car of the present embodiment
When being installed on vehicle body with electric water pump fixing device, the Vehicular electric water pump fixing device can be pacified by four fixing holes
Loaded on vehicle body, and together with electric water pump can be securely attached to by auxiliary stand with main support.
In the present embodiment, the internal diameter in the hole formed between the auxiliary body frame and the main support should be less than electric water pump
External diameter so that when electric water pump is fixed, between the electric water pump and the auxiliary body frame and the main support
Interference fit is formed between the hole formed.
The Vehicular electric water pump fixing device of the present embodiment when in use, when the electric water pump be located at the arc-shaped slot
When interior, the thickness face of described two connecting plates is fitted with electric water pump, then links the hook of auxiliary stand and main support, with
Position is linked for rotating shaft, auxiliary stand is compressed, finally passes through bolt out of auxiliary stand hole, is consolidated with the welding on main support
Fixed nut, which coordinates, to be tightened, that is, completes assembling.Thus, the utility model has the advantages that：
First, it is simple to manufacture, it is only necessary to which the shape is achieved that by the bending to metal plate；
Second, stock utilization is high, and after metal plate support expansion, profile is rectangular, therefore with very high material profit
With rate.
3rd, the principal vibration direction of electric water pump is respectively positioned in the plane of water inlet axis, passes through " several " word
Shape structure, the principal vibration of electric water pump can be effectively suppressed.
4th, the utility model compact conformation is easy to assembly, can be widely applied to passenger car field.
In above-mentioned assembling process, the main support that bolt is connected is not fit not necessarily with the mating surface of auxiliary stand
's.Chosen when reason is to design than the larger magnitude of interference, but there is tolerance, the external diameter of electric water pump in the manufacture of actual bracket
, now can be by the screw-in length of adjustment bolt, to offset the influence that change in size is brought, it is ensured that electronic there is also tolerance
The clamping force of water pump is in the state that meets the requirements.And actually only need to control the screw-down torque of bolt, you can realize and ensure electronic
The purpose of water pump clamping force, with very strong operability.Only in the case where all sizes are limit tolerance, main support
Fitted with the mating surface of auxiliary stand.
Structures shape of the present utility model main support is in the directional stiffness perpendicular to electric water pump water inlet axis very big；
And the vibration of electric water pump is mainly derived from inner rotator produced by the rotation of water inlet axis, i.e., its principal vibration direction is being hung down
It is identical with the maximum rigidity direction of main support directly in the plane of water inlet axis, can so have good mode, to car
The vibration very little of body transmission.
Fig. 5 has sketched the punch-out technical process of main support, and the main support sheet material required in blanking is rectangle, shape
Rule.Waste material produced by blanking operation after, a middle block-shaped rule can be reused, and others are useless
Material is few, then it is bent i.e. plastic.Whole manufacturing process is simple, and stock utilization is high.
Fig. 6 has sketched the technical process of auxiliary stand, rectangle plate of the auxiliary stand in blanking for rule.Produced during blanking
Raw waste material is few, with very high stock utilization.Overall structure is simple, is plastic by a punching press.
For ease of description, the quality of embodiment is not only represented for the sequencing of above example.
Finally it should be noted that：Above example is only to illustrate the technical solution of the utility model, rather than its limitations；
Although the utility model is described in detail with reference to the foregoing embodiments, it will be understood by those within the art that：
It can still modify to the technical scheme described in foregoing embodiments, or which part technical characteristic is carried out etc.
