Description
Technical field
The utility model relates to lining erection unit field, relates in particular to a kind of press-loading apparatus of lining.
Background technology
Lining was generally used in coordinating of axle and hole, and it is mainly used in preventing parts depreciation.In general, lining and hole adopt interference fit, and adopt matched in clearance with axle.Lining is installed in hole by the mode press-fiting, to well located in hole.
Be installed as example with the lining in centrifuge spiral case, bushing press-mounting entered in spiral case, form the interference fit that cooperation is 0.005mm-0.08mm for H7/p7, the magnitude of interference.In prior art, conventionally the mode that adopts a long bolt to coordinate with plain nut, long bolt is arranged in workbench, briquetting is installed in the one end that is positioned at workbench top, be positioned at one end fixed installation plain nut of workbench below, operating personnel adopt spanner that screw rod is screwed onto in nut, thereby screw rod drives briquetting to move downward, lining are pressed into spiral case.Which wastes time and energy, and press-fiting a lining needs 20-30 minute conventionally, and labor strength is very large.In addition, once spanner and screw rod slippage easily cause industrial accident, operating personnel's personal safety is exerted an influence.
Existing the problems referred to above of bushing press-mounting device based on prior art, therefore, provide a kind of press-loading apparatus of new lining, significant.
Utility model content
For addressing the above problem, the utility model provides a kind of press-loading apparatus of lining, and it can realize the mechanically actuated of bushing press-mounting, and simple in structure.
For achieving the above object, the press-loading apparatus of lining of the present utility model, comprise workbench, hollow hydraulic cylinder, screw rod and the briquetting for described lining is exerted pressure, described briquetting is positioned at described workbench top, described hollow hydraulic cylinder is fixedly installed on described workbench below, described screw rod one end is positioned at described workbench top, and the other end passes the piston of described briquetting and described hollow hydraulic cylinder and fixes by nut.
Preferably, described hollow hydraulic cylinder drives by air-driven hydraulic pump.
Preferably, described nut is halfnut.
Preferably, described workbench top is fixedly installed locating piece.
Preferably, described hollow hydraulic cylinder is fixed on described workbench below by contiguous block.
The press-loading apparatus of lining of the present utility model, drives the mechanical press mounting of realizing lining by hollow hydraulic cylinder, effectively guaranteed operating personnel's personal safety.Adopt halfnut, for convenience detach, improve the efficiency press-fiting.And, the press-loading apparatus of lining of the present utility model, simple in structure, cost is low.
Accompanying drawing explanation
Fig. 1 is the structural representation of the press-loading apparatus of lining of the present utility model;
Fig. 2 is that the master of nut in Fig. 1 looks schematic diagram;
Fig. 3 is the top view of Fig. 2.
The specific embodiment
Below, by reference to the accompanying drawings, structure of the present utility model and operation principle etc. are further described.
Referring to Fig. 1, the press-loading apparatus of lining of the present utility model, comprises workbench 1, hollow hydraulic cylinder 2, screw rod 6 and the briquetting 5 for lining 20 is exerted pressure.Workbench 1 comprises at least two gripper shoes 101 of vertical setting and is positioned at the horizontally disposed installing plate 102 of these gripper shoe 101 tops.Briquetting 5 is positioned at workbench 1 top, and briquetting 5 is unfixing with workbench 1.Hollow hydraulic cylinder 2 is fixedly installed on workbench 1 below, is arranged in the space that installing plate 102 and gripper shoe 101 form.Screw rod 6 one end are positioned at workbench 1 top, and the other end is also fixing by nut 8 through the piston (not indicating in figure) of briquetting 5 and hollow hydraulic cylinder 2.This briquetting 5, for directly lining 20 being exerted pressure, in the time that the piston of hollow hydraulic cylinder 2 moves downward, promotes nut 8 and screw rod 6 and moves down, and then drives this briquetting 5 that lining 20 is press-fited to parts 30(to be press-fited as the spiral case of centrifuge) in.
Hollow hydraulic cylinder 2 can be fixed on installing plate 102 belows by contiguous block 3, specifically can adopt many conventional connected modes, as be threaded etc.Certainly, it also can be directly fixed on installing plate 102 belows, the concrete visual selecting factors that waits easy for installation.
The driving of hollow hydraulic cylinder 2 may be implemented in a variety of ways, and as a kind of mode, hollow hydraulic cylinder 2 drives by air-driven hydraulic pump.Air-driven hydraulic pump 7 can be selected the XA11G model of En Paike (ENERPAC), and this air-driven hydraulic pump 7 can produce the hydraulic pressure of 700bar.Hollow hydraulic cylinder 2 can be selected the RCH206 model of En Paike, and under the pressure of 700bar, bearing capacity is 20T, and in the time that air-driven hydraulic pump 7 is worked, the large pressure that at least can realize the magnitude of interference and be 0.05mm-0.2mm is pressed into action.
As a kind of preferred version, nut is halfnut.Adopt halfnut, easy accessibility, has improved the efficiency that press-fits of lining.Particularly, referring to Fig. 2, Fig. 3, this halfnut 8 comprises left half-nut 801, right half-nut 802 and connecting pin 803, right half-nut 802 offers groove 804 along sidepiece, one side of left half-nut 801 has the protuberance 805 that can embed in this groove 804, simultaneously on the sidewall that forms groove 805 and all to offer cross section on protuberance 805 be semicircular hole (not indicating in figure), in the time that the protuberance 804 of left half-nut 801 embeds in the groove 805 of right half-nut 802, two semicircular holes can form a circular hole that holds connecting pin 803.
Need for convenience the location of the parts of mounting bush, above workbench 1, be fixedly installed locating piece 4, press-fit parts 30 and locate for treating.
Continue referring to Fig. 1, it shows the shift motion of the piston of hollow hydraulic cylinder.When use, parts 30 to be installed are positioned on locating piece 4, lining 20 is positioned on parts 30 to be installed, screw rod 6 is passed to briquetting 5, and successively through the piston of lining 20, parts to be installed 30 and hollow hydraulic cylinder 2, tightened nut 8 at the end of screw rod 6, now ready, the piston of hollow hydraulic cylinder 2 is arranged in figure upper side position.Start air-driven hydraulic pump 7, drive the piston of hollow hydraulic cylinder 2 to move downward, piston promotes nut 8 and screw rod 6 moves downward, and moves to the lower position in figure, thereby drive briquetting 5 to move downward simultaneously, lining 20 is pressed into parts 30 complete operations to be installed.
Above, be only schematic description of the present utility model, it will be recognized by those skilled in the art that and do not departing from the basis of operation principle of the present utility model, can make multiple improvement to the utility model, this all belongs to protection domain of the present utility model.
