4, anticreep boss 4 is interference fitted at 1 aperture of mounting hole, and Bowl Plug 5, Bowl Plug 5 and 1 interference of mounting hole are socketed on compression bar head 3
Cooperation.
Specifically, in order to keep press mounting tool overall structural strength higher, compression bar main shaft 2, compression bar head 3 and anticreep boss 4 one
Body cutting forming, overall structure are more stable.
Specifically, it for the ease of adjusting different press fitting depth, compression bar main shaft 2 and the integrated cutting forming of anticreep boss 4, presses
Head 3 is set as stretching structure and is detachably connected between compression bar main shaft 2, and spiral shell between compression bar head 3 and compression bar main shaft 2 can be used
The mode of line connection, to adjust the length of compression bar head 3 and then adjust press fitting depth.
Specifically, the settable triangular prism of this prism structure, tetragonous as shown in figure 3, anticreep boss 4 is set as prism structure
Column etc., shown in Fig. 3 is tetragonous rod structure, and the central axis of anticreep boss 4 is overlapped with the central axis of compression bar head 3, makes to prevent
Every seamed edge outside de- boss 4 outwardly against deformation, makes the aperture of mounting hole 1 become irregular shape in the aperture of mounting hole 1
Shape effectively prevents the risk that Bowl Plug falls off outward.
Specifically, the inside of compression bar head 3, which is inlayed, is provided with magnet block 6, even if the pressure by way of interference fit of magnet block 6
In the inlaid hole for entering compression bar head 3, makes being adsorbed on compression bar head 3 tightly under the action of magnet block 6 of Bowl Plug 5, do not shake not
It falls off, facilitates subsequent press fitting；Magnet block 6 may be provided with one, and be arranged at the central axis of compression bar head 3 or magnet
Block 6 is provided with multiple, and multiple magnet blocks 6 are evenly arranged along the central axis of compression bar head 3, makes to the adsorption capacity of Bowl Plug 5 more
Uniformly, the situation of absorption skew is avoided.
Optimally, the end face of compression bar head 3 is set as the curved-surface structure 31 to match with 5 inner wall shape of Bowl Plug, bending
Radian is consistent with the inner wall shape of Bowl Plug 5, forms location fit, while also increasing the contact of Bowl Plug 5 with compression bar head 3
Area is more uniformly stressed when ensure that press fitting, improves press fitting quality；Optimally, the outside of compression bar main shaft 2 is provided with anti-skidding
Structure 21 can be used special checkering tool and process staggered tiny groove, can also be socketed antiskid glue sleeve etc., increase hand
Frictional force is held, effectively prevents from tapping the rubber sleeve phenomenon that may occur when being pressed.
Embodiment 1: as shown in figure 3, the process of this press mounting tool is: first by compression bar main shaft 2, compression bar head 3 and anti-
The de- preliminary cutting forming of 4 integral type of boss, then processes the inlaid hole of embedded magnet block 6 on compression bar head 3, and by corresponding magnetic
In this inlaid hole of 6 force fit of iron block, curved-surface structure 31 then is processed in 3 overall structure of compression bar head of installation magnet block 6,
The anti-skid structures such as annular knurl 21 are finally processed on compression bar main shaft 2.
It is with the process that this press mounting tool is pressed Bowl Plug: firstly, compression bar head 3 of the selection containing corresponding size
Bowl Plug 5 is manually installed on compression bar head 3 by press mounting tool, and the curved-surface structure 31 and 5 inner wall of Bowl Plug of 3 front end of compression bar head are fixed
Position cooperates, and the magnet block 6 on compression bar head 3, which adsorbs Bowl Plug 5, to be fixed；Then, when Bowl Plug 5 is stably mounted at compression bar head 3
After upper, the alignment engine cylinder of compression bar head 3 is covered the peace for being used to install Bowl Plug 5 by the annular knurl position of man-hour manually hand-held compression bar main shaft 2
Hole 1 is filled, compression bar main shaft 2 is rapidly and uniformly firmly tapped using hammer, Bowl Plug 5 is pressed into mounting hole 1, when compression bar main shaft 2
Step surface contacted with 1 end face of mounting hole, while the pointed part of anticreep boss 4 has penetrated the chamfer site of mounting hole 1, installation
Hole 1 produces deformation in the case where the extruding of anticreep boss 4 destroys, and the accident that effectively preventing Bowl Plug 5 may occur falls off, this
When Bowl Plug 5 be installed in place.
Embodiment 2: as shown in figure 4, the process of another press mounting tool is: first that compression bar main shaft 2 and anticreep is convex
The preliminary cutting forming of 4 integral type of platform drills out threaded hole in compression bar main shaft 2 and anticreep boss 4, then processes corresponding size
Compression bar head 3 processes the external screw thread with the cooperation of this threaded hole in 3 end of compression bar head, then processes embedded magnet on compression bar head 3
The inlaid hole of block 6, and by this inlaid hole of corresponding 6 force fit of magnet block, it is then whole in the compression bar head 3 of installation magnet block 6
Curved-surface structure 31 is processed in body structure, and the anti-skid structures such as annular knurl 21 are finally processed on compression bar main shaft 2.
The process that Bowl Plug is pressed with this press mounting tool unlike the first embodiment, according to press fitting before press fitting
Depth requirements adjust the length of compression bar head 3 first, i.e., by turn compression bar head 3, extend compression bar head 3 relative to compression bar main shaft 2
Or shorten, this structure not only increases the versatility of the components of press mounting tool, and replacement easy to disassemble, improves indirectly
The service life of this press mounting tool.
To sum up, the utility model structure is simple, versatile, realizes the positioning during being pressed and fixes, effectively prevent
The risk that Bowl Plug falls off outward under any circumstance, improves press fitting quality, reduces press fitting cost.
The above, some principles of the utility model that only explains through diagrams, this specification are not intended to this is practical
It is novel to be confined in the shown specific structure and the scope of application, thus it is all it is all may be utilized accordingly modify and wait
Jljl belongs to the applied the scope of the patents of the utility model.
