Description
Technical field
The utility model is related to oil pump fixture technology fields, more particularly, to a kind of oil pump rack clamping structure.
Background technology
Lubricating oil pump is the key component of engine lubrication system, and the accuracy of manufacture directly influences the performance of engine and makes
Use the service life.Oil pump accessory more most at this stage, machine can all influence the assembly after assembling because of itself precision problem after adding
Performance, especially shape are the product of profiled shape, the machine add mode as described in Fig. 1 and Fig. 2：It is integrally wrapped using elastic collet
Shape, side wall integrally contact clamping.Disadvantage is as follows：For product design due to being by die cast, thermoforming can be variant after shrinking,
And product side wall has pattern draft, this will make elastic collet when clamping product, the balance of greatly possible not clamping product
Point, during converted products, product has loosening, and Product Precision can not ensure.The manufacture difficulty of elastic collet is larger, very
The inner cavity pinch form for being difficult to guarantee elastic collet is consistent with product design, is both needed to manually repair a die every time, consistency is poor.
Utility model content
In order to overcome above-mentioned existing technological deficiency, the purpose of this utility model is to provide one kind being directed to oil pump outer wall
Polymorphic structure is clamped at two, and product work in-process is effectively prevent to rotate, and linear contact compresses, and firmly pressure clamps product
New oil pump machine installs clamping structure additional.
In order to achieve the above object, the utility model is achieved through the following technical solutions：
The technical program is that a kind of new oil pump machine installs clamping structure additional, including pedestal, special-shaped locating piece, special-shaped compact heap and
Support column；The abnormity locating piece is fixedly mounted on pedestal；Special-shaped compact heap is movably arranged on pedestal；Special-shaped locating piece with
It is fixed with support column on pedestal between special-shaped compact heap；It is not right that special-shaped locating piece is formed oil pump side wall with special-shaped compact heap
Claim clamping.
As an optimization, the special-shaped locating piece is positioned using special-shaped line, and positioning surface is knife edge structure；Special-shaped compact heap is adopted
It is compressed with special-shaped line, seal face is knife edge structure.
As an optimization, the special-shaped compact heap by special-shaped compact heap support base and is tightened bolt and is mounted on the base.
Compared with prior art, the utility model has the beneficial effects that：This fixture makes simply, using common wire cutting
It is the making that lathe can complete fixture, the compressed part shape and oil pump side wall of the positioning region of special-shaped locating piece and special-shaped compact heap
Polymorphic structure be adapted, designed according to different oil pump sidewall profile shapes, by compatible with oil pump outer wall different at two
Shape structure is clamped, and can be effectively prevented product and be rotated in process；Meanwhile the variation of product design is required not
Height is clamped using knife edge structure, forms empty avoiding to other positions of oil pump, thus the difference of outer shape does not interfere with
The stress for compressing point, effectively makes at positioning and compression position is in and completes to be bonded, and impaction state；Positioning surface and seal face use
The shape of falling the edge of a knife, only line contact, and non-face contact is effectively prevented influence of the product design pattern draft to stress, edge-shaped
Shape only line contacts, and so that its pressure is increased, can firmly press clamping product.
Description of the drawings
The utility model will illustrate by example and with reference to the appended drawing, wherein：
Fig. 1 is that oil pump machine installs folder schematic diagram additional in the prior art.
Fig. 2 is A in Fig. 1 to structural schematic diagram.
Fig. 3 is the main structure schematic diagram of the utility model.
Fig. 4 is A in Fig. 3 to structural schematic diagram.
It is marked in figure：Pedestal 1, special-shaped compact heap 3, support column 4, special-shaped compact heap support base 5, is tightened special-shaped locating piece 2
Bolt 6.
Specific implementation mode
Below in conjunction with the accompanying drawings, the utility model is described in detail.
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only used to explain
The utility model is not used to limit the utility model.
Embodiment 1, as shown in Figures 3 and 4, the utility model are that a kind of new oil pump machine installs clamping structure, including bottom additional
Seat 1, special-shaped locating piece 2, special-shaped compact heap 3 and support column 4；The abnormity locating piece 2 is fixedly mounted on pedestal 1；Abnormity pressure
Tight block 3 is movably arranged on pedestal 1；It is fixed with support column 4 on pedestal 1 between special-shaped locating piece 2 and special-shaped compact heap 3；
Special-shaped locating piece 2 forms asymmetric clamping with special-shaped compact heap 3 to oil pump side wall；The abnormity locating piece 2 is fixed using special-shaped line
Position, positioning surface are knife edge structure；Special-shaped compact heap 3 is compressed using special-shaped line, and seal face is knife edge structure；The abnormity pressure
Tight block 3 is by special-shaped compact heap support base 5 and tightens bolt 6 on pedestal 1, and special-shaped compact heap support base 5 is fixedly mounted
On pedestal 1, tightens bolt 6 and the elasticity of the compression oil pump of special-shaped compact heap 3 is adjusted.
Under the premise of ensureing clamping intensity, select oil pump one side wall special-shaped part as the positioning surface of special-shaped locating piece 2, then
Side wall special-shaped part at one is selected to compress point as the activity of special-shaped compact heap 3, special-shaped compact heap 3 adjusts position by tightening bolt
It sets and oil pump is compressed, auxiliary is supported using support column 4, and the mode of supporting-point carries out clamping at three.This fixture makes
Simply, it is making that lathe can complete fixture, the positioning region of special-shaped locating piece 2 and special-shaped compact heap using common wire cutting
3 compressed part shape is adapted with the polymorphic structure of oil pump side wall, is designed according to different oil pump sidewall profile shapes, is passed through two
Place's polymorphic structure compatible with oil pump outer wall is clamped, and can be effectively prevented product and be rotated in process；Meanwhile it is right
The variation of product design is of less demanding, is clamped using knife edge structure, forms empty avoiding to other positions of oil pump, thus shape
The difference of shape does not interfere with the stress for compressing point, effectively makes at positioning and compression position is in and completes to be bonded, and compress shape
State；Positioning surface and seal face use the shape of falling the edge of a knife, only line to contact, and non-face contact is effectively prevented product design pattern draft
Influence to stress, the shape of falling the edge of a knife only line contact, so that its pressure is increased, can firmly press clamping product.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
All any modification, equivalent and improvement etc., should be included in the utility model made by within the spirit and principle of utility model
Protection domain within.
