Abstract
It the utility model is related to a kind of spinning finishing oil pump foreboard, including finishing oil pump foreboard body, the center of the finishing oil pump foreboard body has spindle hole, side is stretched into the positioning step hole for being used to position placement outside framework oil seal in the main shaft of the spindle hole, the inner side in the positioning step hole has circular oil suction chamber, and the oil suction chamber communicates with the positioning step hole and the diameter of the oil suction chamber is less than the diameter in the positioning step hole.The utility model is when processing oil suction chamber because oil suction chamber is the circular channel-shaped silk floss structure that is communicated with positioning step hole, and when processing oil suction chamber, processing, which is got up, just facilitates easy, and processing cost also reduces, and efficiency also improves, and can equally meet the requirement of user.
Description
Technical field
It the utility model is related to spinning finish pump technical field, and in particular to a kind of spinning is with finishing oil pump foreboard.
Background technology
The spinning finishing oil pump gear pump of spinning finish (be used for convey) the outside framework oil seal of foreboard installation site, such as
Shown in Fig. 1, there is a diameter of 24.6mm positioning step 3 for mounting framework oil sealing in the outside of spindle hole 1, with diameter
The oil suction chamber 2 of an annular groove-shaped is formd for 14mm step, the outside of positioning step 3 has tapered portion 4, positioning step 3
For the location and installation of the outside framework oil seal to installation, in oil suction chamber of the inner side of positioning step 3 formed with an annular sealing
2.But in process, the annular groove of a diameter of 24.6mm step and a diameter of 14mm step formation is very bad adds
Work, process tool are often fractureed, and along with the material of part is 9Cr18Mo, material relative difficult itself is processed, so causing：
First, production cost is higher；2nd, processing efficiency is relatively low.
Utility model content
The purpose of this utility model is solve above-mentioned technical problem and provide a kind of spinning finish of convenient processing
Pump foreboard.
To achieve the above object, the utility model adopts the following technical scheme that：
A kind of spinning finishing oil pump foreboard, including finishing oil pump foreboard body, the center tool of the finishing oil pump foreboard body
There is spindle hole, side is stretched into the positioning step hole for being used to position placement outside framework oil seal in the main shaft of the spindle hole, it is described fixed
The inner side of position stepped hole has a circular oil suction chamber, the oil suction chamber communicated with the positioning step hole and the oil suction chamber it is straight
Footpath is less than the diameter in the positioning step hole.
The rear end face of the finishing oil pump foreboard body is provided with the side fuel feed hole communicated with oil suction chamber, the side oil-feed
Hole is two, the symmetrical outside for being arranged on axis hole.
The oilhole of setting on the circular wall of the oil suction chamber and the fuel feed hole on the side end face of finishing oil pump foreboard body
Communicate.
The utility model has the positioning for being used for positioning placement outside framework oil seal by stretching into side in the main shaft of the spindle hole
Stepped hole, the inner side in the positioning step hole have a circular oil suction chamber, the oil suction chamber communicated with the positioning step hole and
The diameter of the oil suction chamber be less than the positioning step hole diameter, so make oil suction chamber from original groove-like structure be changed into
The circular slot structure that positioning step hole communicates, so processing get up just to facilitate easy, and processing cost also reduces, and efficiency also carries
Gao Liao, and can equally meet the requirement of user.

Embodiment
Below, substantive distinguishing features of the present utility model and advantage are further described with reference to example, but this practicality is new
Type is not limited to listed embodiment.
Referring to shown in Fig. 2-5, a kind of spinning finishing oil pump foreboard, including finishing oil pump foreboard body, before the finishing oil pump
The center of plate body has spindle hole 1, and stretching into side in the main shaft of the spindle hole has for positioning determining for placement outside framework oil seal
Position stepped hole 3, the inner side in the positioning step hole have circular oil suction chamber 2, the oil suction chamber and positioning step hole phase
The diameter of logical and described oil suction chamber is less than the diameter in the positioning step hole, and the outboard end in the positioning step hole has tapered portion
4。
Wherein, the rear end face of the finishing oil pump foreboard body is provided with the side fuel feed hole 8 communicated with oil suction chamber, the side
Face fuel feed hole is two, the symmetrical outside for being arranged on axis hole.
The axis of the side fuel feed hole 8 is parallel with the axis of spindle hole 1.
Wherein, the surface of the finishing oil pump foreboard body has screw mounting hole 6, for by finishing oil pump foreboard body with after
Plate is connected by screw, and the screw mounting hole 6 is 6, is arranged symmetrically in two-by-two on the table of finishing oil pump foreboard body.
Wherein, on the side end face of the oilhole 5 of the setting on the circular wall of the oil suction chamber and finishing oil pump foreboard body
Fuel feed hole 7 communicates, the axis of the fuel feed hole 7 and the axis perpendicular of spindle hole 1.
In the utility model, the diameter that a oil suction chamber substantially exactly bottom of chamber is provided with spindle hole is less than positioning step
The stepped hole in hole, the diameter of the oil suction chamber are more than the hole of the diameter of the spindle hole, connect with positioning step hole and form one
Individual multi-stage stairs hole, and communicated with spindle hole, and central axis overlaps.
It should be noted that in the utility model, except oil suction chamber by original annular groove-shaped is changed to communicate with spindle hole 1
Circular cavity outside, others explanation structures, such as charging hole, the structure of the foreboard of pump of the prior art is identical, is existing
There is technology, to this it will not be described its operation principle process.
It should be noted that in the utility model, a diameter of 24mm in the positioning step hole simultaneously has tapered portion, so
Outside framework oil seal is easily installed, the hole depth 13mm in the positioning step hole, the depth of the oil suction chamber is 8mm, can equally form one
The oil suction chamber of individual sealing.The such change of structure, processing is just relatively easy, and processing cost also reduces, and efficiency also improves,
And it can equally meet the requirement of user.
The utility model is changed by such structure, a bit all without the performance for influenceing finishing oil pump.After improvement
Finishing oil pump assemble after, it is completely qualified by flow test, the flow of finishing oil pump in our factory.And user's use is issued,
The requirement of user can equally be met, effect is fairly obvious.
Described above is only preferred embodiment of the present utility model, it is noted that for the common skill of the art
For art personnel, on the premise of the utility model principle is not departed from, some improvements and modifications can also be made, these improve and
Retouching also should be regarded as the scope of protection of the utility model.
