Abstract
The utility model discloses a rapid sealing and installing device of an auxiliary hole. The rapid sealing and installing device of the auxiliary hole comprises a pressing column and a pressing ball, wherein the cross section of the pressing column corresponds to the cross section of the auxiliary hole and a containing cavity penetrating through the end face at one side is formed in the pressing column, the outer diameter of the pressing ball is in interference fit with the inner diameter of an opening of the containing cavity. The rapid sealing and installing device of the auxiliary hole is simple in structure, convenient to operate, small in installation size, capable of achieving rapid assembly of a sealing body, high in assembling efficiency, good in sealing effect and particularly suitable for installation of sealing plugs used for sealing the auxiliary holes of hydraulic pieces which are provided with the multiple auxiliary holes and produced in batches.
Description
Technical field
The utility model relates to a kind of quick blocking erecting device that is mainly used in the auxiliary hole on hydraulic parts more such as auxiliary hole or that produce in batches.
Background technique
As shown in Figure 1, existing mechanical parts, if hydraulic parts 1 is in manufacture process, all can form a plurality of auxiliary holes 2, and the general twisted off type plug 3 as shown in Figure 2 that adopts of these auxiliary holes carries out shutoff.Its specific embodiment is: at the interior increase tapped hole 21 of auxiliary hole 2 and conical bore 22 is set in outer end, then after evenly smearing sealer in the occluding body 31 of twisted off type plug 3, occluding body 31 is screwed in auxiliary hole completely, finally with instrument, the body 32 that twists off of twisted off type plug is twisted into two parts.But there is following defect in this blocking technological holes mode: first, add need boring man-hour, tapping opens taper hole, increased workload, and the roughness of taper hole has relatively high expectations, more than generally need to reaching Ra1.6, manufacturing procedure is more; Secondly, when twisted off type plug is installed, operating procedure is more, installation time is longer, and sealing effect is closely related with the quality of sealer, when plug is twisted into two parts, breaking part 33 is uneven, easily affect product appearance and quality (as shown in Figure 3), after installation, twisting off body can not recycle, and material is had to waste.
Model utility content
The purpose of this utility model is to provide a kind of auxiliary hole quick blocking erecting device, to solve the deficiencies in the prior art part.
For achieving the above object, the utility model adopts following technological scheme:
A quick blocking erecting device, comprising: a compression leg, and the cross section of its cross section and described auxiliary hole is corresponding, and in it, is provided with a cavity volume that runs through a side end face; With a pressure ball, the internal diameter interference fit of its external diameter and described cavity volume opening.
As preferably, described compression leg is a metal cylinder.
Further, the length of described compression leg is corresponding with the hole depth of auxiliary hole.
As preferably, the outer side wall of described compression leg is provided with some balancing slits and circular groove point.
As preferably, the bottom surface of described cavity volume is a sphere matching with described pressure ball.
As preferably, the degree of depth of described cavity volume is no less than the external diameter of described pressure ball.
The utility model is simple in structure, easy to operate, installation dimension is less, can realize the quick assembling of occluding body, and efficiency of assembling is high; And sealing effect is good, the seal plug that is specially adapted to the more hydraulic parts auxiliary hole with producing in batches of auxiliary hole is installed.

Now in conjunction with the accompanying drawings and embodiments the utility model is described in further detail.
Embodiment
As shown in Figure 4 and Figure 5, a kind of auxiliary hole quick blocking erecting device described in the utility model, is comprised of compression leg 4 and pressure ball 5.Compression leg 4 is a metal cylinder, and the cross section of the counterbore 23 in its cross section and auxiliary hole 2 is corresponding, and the hole depth of the counterbore 23 in its length and auxiliary hole 2 is corresponding.In compression leg 4, be provided with a cavity volume 41 that runs through a side end face, the opening internal diameter of cavity volume 41 and the external diameter interference fit of pressure ball 5.The bottom surface 43 of cavity volume is a sphere matching with pressure ball 5, and the degree of depth of cavity volume 41 is no less than the external diameter of pressure ball 5.The outer side wall of compression leg 4 is provided with some balancing slits 42 and circular groove point 44.
Specific embodiment of the present utility model is:
As shown in Figure 5, first less demanding in the interior increase degree of depth of auxiliary hole 2 of the hydraulic parts 1 counterbore 23(counterbore roughness corresponding with compression leg with internal diameter, be generally Ra3.2 and just can reach requirement, can directly by common driller, be processed easy processing); Then compression leg 4 is inserted in counterbore 23 and near the bottom of counterbore 23; Finally by drill steel 6(or press are installed) pressure ball 5 integral body are pressed in the cavity volume of compression leg, internal diameter interference fit due to external diameter and the cavity volume opening of pressure ball, therefore pressure ball can force compression leg to circumferential expansion in being pressed into compression leg process, be filled in the rough surface gap of counterbore and force counterbore to produce micro-distortion, make compression leg periphery wall (balancing slit and circular groove point) and hydraulic parts carry out interlock sealing, and the phenomenon such as auxiliary hole can not ftracture, seepage.Can on balancing slit, be coated with sealer, play dual sealing functions.When single or small number are installed, also can realize installation by hand hammer.
