Description
Technical field
The utility model is a kind of assembly apparatus for locating, and belongs to machinery production field.
Background technique
Along with mechanical industry fast development in the world, the prosperity of machine industry whether and the self-water-supply Heisei of machine equipment be the real mark of measurement one state's level of economic development and scientific and technological level.Mechanical seal structure is a kind of structure often adopted in machine building industry, and especially on axle, the structure of seal ring is common especially.On axle, seal ring plays a crucial role in hydraulic pressure or pneumatic system, but it is very high to the requirement of installation environment, once installation environment is affected, just be very easy to damage, simultaneously on axle, Sealing improperly also very easily causes damage because placing, and visible, on axle, seal ring belongs to easy-to-damage element.In the prior art, normally seal ring on axle is pressed between axle and the mounting hole of housing, the endoporus of seal ring on axle is coordinated with axle, cylindrical coordinates with the mounting hole of housing, to reach the effect of sealing, but when being pressed into seal ring on axle on axle because seal ring on axle is not located, on axle, each position pressure of seal ring ring edge in the process of press-in can be uneven, cause seal ring deflection on axle, and then make seal ring with outer and housing decentraction on axle, to cause on axle seal ring easily by the aperture scratch of the mounting hole of housing, and then cause poor sealing between axle and housing, the normal operation of impact machinery, so need a kind of assembly apparatus for locating to solve this problem.
Summary of the invention
In view of this, the purpose of this utility model is to provide a kind of assembly apparatus for locating, easy to use, convenient operation, and structure is simple, time saving and energy saving.
The purpose of this utility model is realized by following technological means: a kind of assembly apparatus for locating, by nut, pad, spring, coning sleeve, positioning ring, seal groove on axle, block is installed, housing seal groove, installation shaft, housing, positioning hole and locating stud composition, described nut is arranged on the front end of installation shaft by screw thread, described pad is arranged on the lower end of nut, described spring fitting is in the upper end of housing, described positioning ring is fixedly mounted on the middle part of the outer surface of housing, on described axle, seal groove is arranged on the middle part of installation shaft, described installation block has two and symmetry is fixedly installed on the bottom of installation shaft, described housing seal groove is opened in the middle part of shell inner surface, described housing snugly fits into the outside of installation shaft, described locating stud and positioning hole closely cooperate installation.
Further, the middle part of described housing is installed with coning sleeve.
Further, the lower left corner of described housing is provided with positioning hole.
Further, the upper surface of described installation block is provided with locating stud.
The beneficial effects of the utility model: a kind of assembly apparatus for locating of the present utility model, utilize taper fit on tapering ring and axle, make seal ring and housing on axle concentric, the use of block and locating stud is installed, to ensure that pressure uniform distributes, make seal ring not crooked, like this seal ring on axle is being pressed in the process between axle and housing, remain that on axle, seal ring with outer is concentric with housing, axle is in operation process, on axle, seal ring is concentric with housing, on axle seal ring would not and housing between scrape damage, avoid the phenomenon that the housing that causes because of Rig up error makes sealing reduce to the scratch of seal ring on axle, also extend the working life of seal ring on axle simultaneously.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further described.
Fig. 1 is a kind of assembly apparatus structural representation for locating of the utility model.
Embodiment
Below with reference to accompanying drawing, the utility model is described in detail,
Embodiment 1
Refer to Fig. 1, the utility model provides a kind of technological scheme: a kind of assembly apparatus for locating, by nut 1, pad 2, spring 3, coning sleeve 4, positioning ring 5, seal groove 6 on axle, block 7 is installed, housing seal groove 8, installation shaft 9, housing 10, positioning hole 11 and locating stud 12 form, nut 1 is arranged on the front end of installation shaft 9 by screw thread, pad 2 is arranged on the lower end of nut 1, pad 2 plays the locking effect to nut 1, spring 3 is arranged on the upper end of housing 10, coning sleeve 4 is fixedly mounted on the middle part of housing 10, coning sleeve 4 is for keeping the coaxality that installation shaft 9 is identical with housing 10, positioning ring 5 is fixedly mounted on the middle part of the outer surface of housing 10, positioning ring 5 is for the auxiliary positioning of whole device, on axle, seal groove 6 is arranged on the middle part of installation shaft 9, on axle, seal groove 6 is for laying seal ring, on axle, seal groove 6 can select different sizes according to different functions, block 7 is installed and has two and symmetry is fixedly installed on the bottom of installation shaft 9, block 7 is installed for making positive pressure suffered on seal ring even, housing seal groove 8 is opened in the middle part of housing 10 internal surface, housing seal groove 8 is for placing seal ring, housing 10 snugly fits into the outside of installation shaft 9, positioning hole 11 is arranged on the lower left corner of housing 10, locating stud 12 is arranged on the upper surface installing block 7, locating stud 12 and positioning hole 11 closely cooperate.
In use, first adjusting nut 1, seal ring to be arranged on axle in seal groove 6, then installation shaft 9 is slowly installed in housing 10, coning sleeve 4 can keep the coaxality that installation shaft 9 is identical with housing 10, and then seal ring is stablized, do not tilt, block 7, locating stud 12 and positioning hole 11 are installed and can ensure that the positive pressure suffered by seal ring is even.
What finally illustrate is, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
