Abstract
The utility model discloses a special movable centre for automobile oil pumps, which comprises a centre body and a sealing pressing block, wherein the side of the centre body is provided with an opening, one end of the centre body is provided with a taper shank, the other end of the centre body is provided with a stepped hole communicated with the opening, a radial bearing and a thrust bearing are sequentially mounted in the stepped hole from the outside to the inside, the sealing pressing block is cylindrical, and is provided with a positioning boss along the periphery of the outer wall of the sealing pressing block, the sealing pressing block is mounted in the inner bore of the radial bearing, and the positioning boss of the sealing pressing block is arranged between the radial bearing and the thrust bearing. The inner bore, the periphery and the end surface of an oil pump can be machined as long as the movable centre is clamped only one time, the coaxiality precision of the outer diameter and the inner bore of the oil pump is highly uniform, the production efficiency is high, the labor intensity of workers is low, the consumption of manpower resource and the occupation of equipment are reduced, and the manufacturing cost is reduced.
Description
Technical field
The utility model belongs to the lubricating pump of automobile processing technique field, particularly relates to a kind of rolling center for lubricating pump of automobile processing.
Background technology
Automobile engine oil pump length and endoporus aperture ratio are 15, are the elongated thin-wall workpiece of typical case.This workpiece is the microdiecast aluminium alloy, wall thickness 4.5.Pump housing external diameter is the travelling gear positioning datum, and endoporus is gearing shaft, and the axiality of endoporus and external diameter directly affects lubricating oil pump service life and gear drive sound.In order to meet this axiality requirement, the conventional machining scheme is that the special-purpose inner hole boring tool of machining center outfit is completed the endoporus making, then configures the Small Taper mandrel, and workpiece is located with mandrel, uses nut check, fine turning outer circle on the High Precision CNC lathe.Due to the impact of fit clearance and the secondary clamping factor of mandrel and pump housing endoporus, oil pump body processing is long non-cutting time, and the coaxial accuracy uniformity is poor, need to carry out exhaustive test, causes that production efficiency is lower, production cost is high.
The utility model content
It is top that the purpose of this utility model just is to provide a kind of lubricating pump of automobile Special movable, solved existing processing scheme lubricating oil pump external diameter and endoporus coaxial accuracy uniformity poor, and production efficiency is low, the problem that production cost is high.
The purpose of this utility model realizes by following technical proposals:
A kind of lubricating pump of automobile Special movable is top, comprise top body and sealed briquette, be provided with opening in top body side, top body one end is provided with taper shank, and the other end is offered the stepped hole that communicates with opening, and stepped hole is installed radial bearing and thrust bearing from outside to inside successively, sealed briquette is cylinder barrel shaped, be provided with positioning boss along its outer wall circumference, sealed briquette is arranged in the endoporus of radial bearing, and its positioning boss is placed between radial bearing and thrust bearing.
Further, described taper shank is Morse taper shank.
Further, described thrust bearing and stepped hole matched in clearance, radial bearing and stepped hole interference fit, sealed briquette and radial bearing endoporus interference fit.
Further, the end face of described radial bearing is with dust cap.
Compared with prior art, the beneficial effects of the utility model are: clamped one time can be completed the processing of lubricating oil pump endoporus, cylindrical and end face, lubricating oil pump external diameter and endoporus coaxial accuracy high conformity, production efficiency is high, labor strength is low, reduce consumption and the hold facility of human resources, reduced manufacturing cost.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is use state diagram of the present utility model.
The specific embodiment
Below in conjunction with specific embodiments and the drawings, the utility model is further described.
as shown in Figure 1, a kind of lubricating pump of automobile Special movable is top, comprise top body 1 and sealed briquette 7, be provided with opening 2 in top body 1 side, top body 1 one ends are provided with Morse taper shank 3, its Morse's taper is No. 5, the other end is offered the stepped hole 4 that communicates with opening 2, stepped hole 4 is installed radial bearing 6 and thrust bearing 5 from outside to inside successively, described radial bearing 6 and stepped hole 4 interference fit, thrust bearing 5 and stepped hole 4 matched in clearance, sealed briquette 7 is cylinder barrel shaped, be provided with positioning boss along its outer wall circumference, sealed briquette 7 is interference fitted in the endoporus of radial bearing 6, its positioning boss is placed between radial bearing 6 and thrust bearing 5.
The end face of described radial bearing 6 is with dust cap.
as shown in Figure 2, in use, lubricating oil pump 8 one ends and machine tool chief axis end face location, rolling center utilizes Morse taper shank 3 and tailstock tool auto lock, lathe starts, tailstock promotion rolling center moves to the other end of lubricating oil pump 8, after sealed briquette 7 end faces and lubricating oil pump 8 end contacts, pressure sensor and displacement transducer guide sealed briquette 7 to meet the requirements of position automatically, then machine tool chief axis starts to drive lubricating oil pump 8 rotations, sealed briquette 7 relies on pressing friction power to realize synchronous rotary with lubricating oil pump 8, lathe tool carries out turning to lubricating oil pump 8 cylindricals, the complete rear lathe tool of turning is return starting point, the opening 2 of internal lathe-tool by top body 1 side, and the stepped hole 4 that communicates with opening 2 enters in lubricating oil pump 8 endoporus, return starting point after completing endoporus turning, then tailstock relies on hydraulic pressure to return starting point, and system is automatically to lubricating oil pump 8 and the residual cutting impurity of the jet removal of tailstock.
Rolling center clamped one time of the present utility model can be completed the processing of lubricating oil pump endoporus and cylindrical, the lubricating oil pump accuracy of form and position is kept by CNC lathe precision fully, there is no clamping and benchmark transformed error, meet design basis, machining benchmark, detection reference three uniform principleies, product is beated inspection-free.Production automation degree is high, and labor strength is low, utilizes the transmission of CNC lathe hydraulic, realizes the workpiece Automatic-clamping and loosens, and after workpiece end face turning was completed, rolling center automatic impaction workpiece end face, avoided the manually-operated tailstock, reduces staff labor intensity.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
