Abstract
The invention discloses a floating centring-type installation device for shaft parts. According to the floating centring-type installation device for shaft parts, an adjusting plug screw is installed on the lower portion of a location seat; a spring is installed in the location seat and located on the upper portion of the adjusting plug screw; a floating slide sleeve is installed on the upper portion of the spring; the excircle of the floating slide sleeve is installed by being in centring slide fit with the inner cavity of the location seat; a bearing is coaxially installed in the upper location hole of the location seat; a shaft is installed in the inner hole of the bearing; the spline portion of the lower portion of the shaft is superposed with the inner hole of the floating slide sleeve; the shaft is coaxial with the location seat. According to the floating centring-type installation device for shaft parts disclosed by the invention, when the shaft and the bearing are installed, the centring and guide of the shaft and the bearing are always kept from workpiece placement to press-fitting completion, thus ensuring smooth and difficulty-blocked press-fitting process, no scratches on a matching surface and assembly quality, reducing a product fault rate, avoiding impact and wear on press-fitting equipment, prolonging the service duration of the equipment, decreasing the cost, meeting the assembly needs of shafts with various length specifications in a certain range, avoiding machining and use for a plurality of location fixtures, decreasing production cost, and increasing working efficiency.
Description
Technical field
The present invention relates to axial workpiece installing area in machine-building assembling, relate in particular to the mounting technique of power steering pump shaft and bearing.
Background technology
At present, to generally adopting positioning seat location, supporting workpiece and pneumatic press to press-fit in the interference assembly technology of power steering hydraulic pump pump shaft and bearing, it is ring bottom in positioning seat location bearing outer shroud, spring bearing, axle and bearing (hole) fall (circle) angle for centering and guiding by it, adopt pneumatic press to be pressed into.It falls (circle) angle for feeling relieved and guidance method this kind of axle and Bearing support, because both cause it to design less in (circle) angle from the restriction of the instructions for use of experiencing, centering and guide effect while making to press-fit are limited, when very easily the skew between two workpiece causes press-fiting, enter head freely even not stuck, thereby scuffing mating surface, affect fit quality, hazard rate is high; Meanwhile, produce and press-fit impulsive force, the long-term wearing and tearing of using meeting aggravation forcing press, improve equipment failure rate.
Summary of the invention
In order to overcome the problems referred to above that occur in power steering hydraulic pump pump shaft and bearing installation, the invention provides a kind of axial workpiece float centrih formula erecting device.
The technical scheme that the present invention adopted is for achieving the above object: axial workpiece float centrih formula erecting device, positioning seat 4 bottoms are installed and are adjusted plug screw 7, positioning seat 4 inside are positioned at adjusts plug screw 7 top mounting spring 6, the sliding sleeve 5 that floats is installed on spring 6 tops, unsteady guide pin bushing 5 cylindricals and positioning seat 4 inner chambers centering are slidably installed, bearing 3 is coaxially installed in the top locating hole of positioning seat 4, axle 2 is installed on bearing 3 endoporus, the splined section of axle 2 bottoms overlaps with unsteady guide pin bushing 5 endoporus, and axle 2 is coaxial with positioning seat 4.
Described adjustment plug screw 7 is for moving up and down structure along positioning seat 4 inside.
Axial workpiece float centrih formula erecting device of the present invention, when realizing installation shaft and bearing, from put into workpiece to having press-fited, remain centering, the guiding of axle and bearing, thereby guaranteeing to press-fit process moves and is smooth and easyly difficult for stuck, matching surface and does not scratch, guarantee assembly quality, reduce hazard rate; Avoided the impact of press-loading device and wearing and tearing, extension device service life, reduced costs; Meet the assembling needs of different lengths specification axle in certain limit, avoid processing, use many cover positioning tools, reduce body and produce cost, operating efficiency is provided.
Accompanying drawing explanation
Fig. 1 is that axial workpiece float centrih formula erecting device of the present invention press-fits pre-structure schematic diagram.
Fig. 2 is that axial workpiece float centrih formula erecting device of the present invention press-fits rear structural representation.
In figure, 1, press ram, 2, axle, 3, bearing, 4, positioning seat, 5, the guide pin bushing that floats, 6, spring, 7, adjust plug screw.
The specific embodiment
Axial workpiece float centrih formula erecting device structure of the present invention as depicted in figs. 1 and 2, positioning seat 4 bottoms are installed and are adjusted plug screw 7, positioning seat 4 inside are positioned at adjusts plug screw 7 top mounting spring 6, the sliding sleeve 5 that floats is installed on spring 6 tops, unsteady guide pin bushing 5 cylindricals and positioning seat 4 inner chambers centering are slidably installed, and bearing 3 is coaxially installed in the top locating hole of positioning seat 4, and axle 2 is installed on bearing 3 endoporus, the splined section of axle 2 bottoms overlaps with unsteady guide pin bushing 5 endoporus, and axle 2 is coaxial with positioning seat 4.
During use, after the guide pin bushing 5 that first will float is put into positioning seat 4, put into spring 6, then screw in to adjust plug screw 7 it is sunk in positioning seat 4, and can regulate according to the length of axle 2; Then bearing 3 is put into the top locating hole of positioning seat 4, made bearing 3 coaxial with positioning seat 4, thereby again axle 2 is put into bearing 3 endoporus, the splined section of axle 2 bottoms is overlapped with unsteady guide pin bushing 5 endoporus, even if axle 2 is coaxial with positioning seat 4, thereby indirectly guaranteed that axle 2 and bearing 3 coaxially feel relieved; Next opening pressure machine, press ram 1 is pressing axle 2 to move down, axle 2 glides along bearing 3 and unsteady guide pin bushing 5, when exceeding, the splined section of axle 2 floats after guide pin bushing 5, the unsteady stressed Compress Spring 6 of guide pin bushing 5 also glides along positioning seat 4 endoporus, until press with the shaft shoulder bearing 3 of axle 2, on final pressure compressing head 1 is automatic, move, can take out the assembly of axle 2 and bearing 3.From axle 2, put into bearing 3 holes to having press-fited, the cooperation by float guide pin bushing 5 and positioning seat 4 all the time remains the coaxial centering of axle and bearing, press-fits to be smooth and easyly difficult for stuck, protection matching surface and not to be scratched, reduction defective products rate; Avoided, to the impact of press-loading device and wearing and tearing, reducing costs; While is versatility also, reduces processing tool quantity, reduces costs and raises the efficiency.That the overall process axis that realization press-fits and bearing are all felt relieved is coaxial, guiding fully, thereby while guaranteeing to press-fit, enter smooth and easy be difficult for stuck, prevent from scratching mating surface, and reduce the impact to forcing press; The needs that press-fit that wherein float, adjustable mechanism can meet different length specification axle within the specific limits, avoid processing, use many cover positioning tools.
The present invention is described by embodiment, and those skilled in the art know, without departing from the spirit and scope of the present invention, can carry out various changes or equivalence replacement to these features and embodiment.In addition, under instruction of the present invention, can modify to adapt to concrete situation and material and can not depart from the spirit and scope of the present invention these features and embodiment.Therefore, the present invention is not subject to the restriction of specific embodiment disclosed herein, and the embodiment within the scope of all the application's of falling into claim belongs to protection scope of the present invention.
