Abstract
The utility model discloses a tool for mounting a main shaft sealing cover. The tool comprises a sleeve and a push mechanism, wherein an accommodating cavity which penetrates through the lower end surface of the sleeve is arranged in the sleeve, and a main shaft can be arranged in the accommodating cavity; the push mechanism is arranged on the sleeve. Optimally, a through hole is formed in the upper end part of the sleeve, and the push mechanism is arranged in the through hole. As a choice, the push mechanism can be a screw and movably penetrates through the through hole. When the tool is used for mounting the main shaft sealing cover, the main shaft sealing cover can be stably pressed in an upper casing of a pump, and a framework oil seal cannot be damaged. More convenient and rapid mounting can be realized, and greater advantages are presented in the massive mounting process of the main shaft sealing cover.
Description
Technical field
The utility model relates to a kind of frock of machinery production manufacture field, is specifically related to a kind of main shaft seal lid mounting tool that is mainly used in the products such as hydraulic pump.
Background technology
At present, in the assembling process such as products such as hydraulic pumps, when main shaft seal covers in being installed to the pump housing, easily produce, make the outside framework oil seal in seal cover occur turning over lip or wearing and tearing, finally cause pump in use to occur leaking oil condition.And, also there is no special-purpose main shaft seal lid mounting tool at present, make main shaft seal lid installation effectiveness lower, be unfavorable for assembling in enormous quantities.
Utility model content
The purpose of this utility model is to provide a kind of main shaft seal simple in structure lid mounting tool, effectively to solve the deficiencies in the prior art part.
For achieving the above object, the utility model adopts following technical scheme:
Main shaft seal lid mounting tool, comprises a sleeve, is provided with the cavity volume that always wears a lower surface and can insert for main shaft in described sleeve; And described sleeve is provided with a delivery device.
As preferably, a through hole is offered in the upper end of described sleeve, and described delivery device is arranged in this through hole.Further preferably, the axis of described through hole overlaps with the axis of described cavity volume.
As a kind of selection, described delivery device is a screw, and activity is located in described through hole.Further, described screw is a soket head cap screw.
As preferably, lateral wall corresponding described cavity volume opening in described sleeve bottom radially extends to form and presents a theatrical performance as the last item on a programme.The diameter of presenting a theatrical performance as the last item on a programme further preferably, is more than or equal to the diameter of end face outside described seal cover.
As preferably, described in present a theatrical performance as the last item on a programme and be provided with limited bayonet.Further preferably, in described limited bayonet, magnet is installed, to facilitate for installing.
As preferably, in described sleeve lateral wall, radially offer at least one through hole.Further preferably, described sleeve lateral wall is offered two through holes, and one for fixing and prevent rotating in same direction by main shaft and frock; Another one is masks peephole.
The utility model, by adopting said structure, can be pressed into reposefully the upper casing of pump by main shaft seal lid while covering for main shaft seal is installed, and can not damage outside framework oil seal; And more convenient and quicker, at main shaft seal, cover and in installation process in enormous quantities, embody larger advantage.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is that the utility model is for installing the working state schematic representation one of main shaft seal lid.
Fig. 3 is that the utility model is for installing the working state schematic representation two of main shaft seal lid.
In figure:
1-sleeve; 11-cavity volume; 12-through hole; 13-present a theatrical performance as the last item on a programme; 14-limited bayonet; 15-through hole; 2-soket head cap screw; 3-pump housing upper casing; 4-main shaft; 5-main shaft seal lid; 6-outside framework oil seal.
Now in conjunction with the accompanying drawings and embodiments the utility model is described in further detail.
The specific embodiment
As shown in Figure 1 to Figure 3, main shaft seal lid mounting tool described in the utility model, is mainly comprised of sleeve 1 and delivery device.
In described sleeve 1, be provided with the cavity volume 11 that always wears a lower surface and can insert for main shaft 4.The through hole 12 that an axis overlaps with cavity volume axis is offered in the upper end of sleeve 1.In sleeve lateral wall, radially offer 15, one of two through holes for rotating in same direction is fixed and prevented to main shaft and frock; Another one is masks peephole.。Lateral wall corresponding described cavity volume opening in sleeve bottom radially extends to form and presents a theatrical performance as the last item on a programme 13, and this diameter of 13 of presenting a theatrical performance as the last item on a programme is more than or equal to the diameter that main shaft seal covers 5 outside end faces; On presenting a theatrical performance as the last item on a programme, be also provided with limited bayonet 14, magnet (not indicating in figure) is installed in limited bayonet, to facilitate for installing.
Described delivery device is a soket head cap screw 2, and activity is located in the through hole of sleeve.
The course of work of the present utility model is as follows:
As shown in Figures 2 and 3, first main shaft seal lid 5 be inserted in gently in main shaft 4 and be placed on the installation site of pump housing upper casing 3, then main shaft seal lid being set level.Then with sleeve of the present utility model, main shaft 4 is inserted in cavity volume and presenting a theatrical performance as the last item on a programme of sleeve is pressed on the outside end face of main shaft seal lid, then by little soket head cap screw from one of them through hole 15(mounting hole) be screwed into, to prevent main shaft and sleeve rotating, upper end soket head cap screw cannot be screwed into main shaft; Finally by soket head cap screw 2, the through hole 12 through sleeve 1 is screwed in the screwed hole of main shaft 4, at soket head cap screw, be screwed in the process of main shaft, the nut of soket head cap screw can promote sleeve and along the axis of main shaft, move all the time, sleeve also promotes main shaft seal lid and along the axis of main shaft, to pump housing upper casing, moves all the time by presenting a theatrical performance as the last item on a programme, until main shaft seal lid is pressed in upper casing; Because main shaft seal lid moves along the axis of main shaft all the time, be not easy to produce, so the outside framework oil seal in seal cover 6 there will not be and turns over lip or wearing and tearing.
