Abstract
The invention relates to a device for assembling a spiral check ring for a hole. The device comprises a pressure head and a guide cone. The pressure head is in a T shape, and the lower portion of the pressure head is conical; and the guide cone is annular, and the inside of the guide cone is in a cone shape matched with the cone shape of the pressure head. A guide pin extending downwards is arranged on the pressure head, and the guide pin can penetrate a hole in the guide cone and enables the pressure head to perpendicularly move. A step is arranged at the lower portion of the guide cone, and the step is in clearance fit with a shaft inner hole of the to-be-installed spiral check ring and extends to the installing position of the spiral check ring. The device has the beneficial effects of being simple in structure, convenient to use and the like, and the assembling efficiency can be greatly improved.
Description
Technical field
The present invention relates to a kind of spiral back-up ring assembling device, be particularly useful for the assembling of hole spiral back-up ring.
Background technology
Part axial play in hole, all can consider its axial limiting during design, is usually all to install spiral back-up ring in the one or both ends in hole.In installation spiral back-up ring process, because installing space is little sometimes, the volume of spiral back-up ring is little in addition, elasticity is comparatively large, and not only efficiency of assembling is low to install spiral back-up ring so artificial, and labour intensity is large.
Summary of the invention
The object of this invention is to provide a kind of hole spiral back-up ring assembling device, described device has easy to use, simple operation and other advantages, greatly can improve efficiency of assembling.
Concrete technical scheme of the present invention is: hole spiral back-up ring assembling device comprises pressure head, guide cone, described pressure head is T-shaped, bottom is taper, guide cone ringwise, the inner taper for matching with pressure head taper, described pressure head is provided with the guide pin to downward-extension, guide cone is arranged porose, guide pin can through the hole in guide cone, pressure head is moved both vertically, the cone element length of described pressure head is not less than the bus length of the inner conical surface of guide cone, ensures that the taper of pressure head can move to the bottom of guide cone; Described guide cone bottom is provided with step, the axle endoporus matched in clearance of described step and spiral back-up ring to be installed, and prolongs the installation site rising to spiral back-up ring.Described pressure head and the cone angle of guide cone are 15 ~ 20 degree, are preferably 16 degree, and the material of pressure head and guide cone is steelwork, conical surface Carburization Treatment.The conical surface of described pressure head is provided with the groove along bus, and the quantity of described guide pin is no less than 2.
The present invention operationally, guide cone lower end leans against on the end face of the axle of spiral ring washer to be installed, step in guide cone extends the inside of axle, and with the internal diameter matched in clearance of axle, spiral back-up ring is put on the conical surface of guide cone inside, again the guide pin cover on pressure head is inserted on the hole of guide cone, to pressing down pressure head.When pressure head lower end touches spiral back-up ring, uniform force is applied in pressure head upper end, spiral back-up ring is steadily moved down, to the end of guide cone, because the end design of guide cone is in the position of installing spiral back-up ring, move to the end of guide cone when spiral ring washer and after deviating from, just in time can be stuck in installation site, ensureing that spiral ring washer is in place.
The present invention is exerted pressure by pressure head, the guiding of guide cone and guide pin, and spiral back-up ring is in place stably; Frustoconical bevel angle can ensure that namely spiral back-up ring can move down stably, and be unlikely to again have excessive stroke, the conical surface of pressure head devises keyway arrangements, reduces the contact area of the pressure head conical surface and guide cone, is convenient to being separated of pressure head and guide cone.Pin on pressure head and the pin-and-hole of guide cone are matched in clearance, achieve the centering function of pressure head.The present invention is simple in structure and convenient in use, and greatly can improve efficiency of assembling.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is embodiments of the present invention schematic diagram.
Detailed description of the invention
As shown in the figure, hole spiral back-up ring assembling device comprises pressure head 1, guide cone 2, described pressure head 1 is T-shaped, bottom is taper, guide cone 2 ringwise, the inner taper for matching with pressure head 1 taper, described pressure head 1 is provided with the guide pin 3 to downward-extension, guide cone 2 is arranged porose, guide pin 3 can through the hole in guide cone 2, pressure head 1 is moved both vertically, and the cone element length of described pressure head 1 is not less than the bus length of the inner conical surface of guide cone 2, ensures that the taper of pressure head can move to the bottom of guide cone; Described guide cone 2 bottom is provided with step, the axle 5 endoporus matched in clearance of described step and spiral back-up ring 4 to be installed, and prolongs the installation site rising to spiral back-up ring 4.Described pressure head 1 and the cone angle of guide cone 2 are 15 ~ 20 degree, are preferably 16 degree, and the material of pressure head 1 and guide cone 2 is steelwork, conical surface Carburization Treatment.The conical surface of described pressure head 1 is provided with the groove along bus, and the quantity of described guide pin 3 is no less than 2.
