The inner sidewall of folder is equipped with and the mutually matched inner conical surface of male cone (strobilus masculinus)；Shifting portion is limited, is used to limit the axial movement of elastic collet chuck；
Positioning power portion is used to control piston cylinder and moves up and down, and piston cylinder is moved up by its own and props up elastic collet chuck, into
And from the through-hole on workpiece to be processed by its stretching；Compressed part is removably connected to the top of piston rod；Power part is compressed,
It is used to control piston rod and moves up and down, and piston rod is moved down by its own workpiece to be processed being pressed on elastic collet chuck
Upper end.Clamping efficiency not only can be improved in the fixture, but also workpiece to be processed is under the action of stretching and compression, it is ensured that it is filled
The stability of folder.
For another example, a kind of centering pressing device structure is also referred in patent CN203542427U, including pedestal, pedestal are
Table tennis bat shape, the center of pedestal disk are equipped with aperture and are connected with support tube, be provided on the disk around support tube several
Evenly arranged circular hole, the two sides of disk are all connected with there are two connecting rod, and circular hole every three are one group and are uniformly distributed.This is practical new
Type realizes interfix set outer circle and directly positions workpiece datum hole, avoids accumulated error caused by positioning datum converts, week
Side pilot hole meets periphery hole and work after processing by the distribution of product drawing size positions is met centered on interfix outer circle
Part datum hole concentricity, another entire annular slab and the big face contact of workpiece, can be used as pressing plate use, instead of pressing plate, operate more square
Just quick.
For another example, a kind of centering compaction fixture is also referred in patent CN202028947U, is included bottom plate, is set on bottom plate
There is cylindricality fixed block, the end of cylindricality fixed block is installed with cylindricality briquetting, is respectively provided with around the surrounding of cylindricality briquetting to extension
The more spokes stretched, the lateral surface of every spoke is respectively the conical surface.The utility model structure is simple, and convenient disassembly is at low cost, ingeniously
The positional relationship of the wonderful internal structure that larger, the complicated workpiece of some sizes is utilized and fixture, so that workpiece is effectively
Fastening on the table, to facilitate production and processing, further improves production efficiency and product quality.
In above-mentioned three kinds of centering pressing devices, still need when centering compresses using to bolt etc. to workpiece
Cooperation is very troublesome, and be also to be limited for the shape of the workpiece of processing to realize, as it is some have it is default
The trouble that the workpiece of position hole and clamping plane is just compared when carrying out positioning compression using above-mentioned three kinds of devices, is less susceptible to reality
It is existing, due to its special structure, need to realize work using the cooperation of the parts such as bolt in multiple orientation of the outer wall of workpiece
The positioning compression of part, structure is complicated, cumbersome.
Utility model content
It is processed the technical problem to be solved by the present invention is to provide a kind of auto parts and components and uses centering compression tooling, it can
The positioning compression of the convenient workpiece with interior location hole and clamping plane.
In order to solve the above technical problems, the technical solution of the utility model are as follows: a kind of auto parts and components processing centering pressure
Tight tooling, innovative point are: including
Centering in the inner cavity of one insertion auto parts and components compresses block main body, and it is a cylindrical body knot which, which compresses block main body,
Structure, outer diameter are greater than the hole size of components；
One is arranged in the cylindric center bridge that centering compresses block main body upper end, and the upper end of the center bridge is circular conical surface, together
When centering compress block main body upper end have one hold center bridge suit cylindric installation protrusion, the outer wall of the center bridge
Bore is consistent with the bore of interior location hole of auto parts and components；
One, which is arranged in centering, compresses holding down assembly in block main body, and described hold down assembly is distributed in including several shapes in a ring
The L shape compact heap of center bridge upper end, hingedly forms between compact heap and center bridge, and is driven by hold-down mechanism and compress automobile zero
The clamping plane of component.
Further, the hold-down mechanism includes a compression axis, which is one by limit section and the common structure of optical axis section
At T shape structure, and limit section bore be greater than optical axis section bore, centering compress block main body medium position also have
Facial expression shaft part runs through the through-hole that entire centering compresses block main body from top to bottom, and the bore of the through-hole is less than the bore of limit section,
Wherein one end of the compact heap is hingedly formed with limit section, and the corner of compact heap is fixed on center bridge by a bolt,
And hingedly formed between compact heap and bolt, the other end of compact heap stretches out outside center bridge.
Further, the outside of the bottom end of the compact heap also has the boss extended downwardly.
Utility model has the advantages that in the present invention, by center bridge and the cooperation to hold down assembly, using calmly
Centering is realized in the cooperation of the interior location hole of heart block and workpiece, cooperates the pressure for realizing workpiece with the clamping plane of workpiece using holding down assembly
Tightly, it is realized to cooperate to the workpiece with interior location hole and clamping plane using the structure type that this built-in centering compresses
Positioning fix, compact-sized, components machinability is good, at low cost, good economy performance.
By the way that the upper end of center bridge is designed as circular conical surface, so that the repetitive positioning accuracy to manipulator is of less demanding, match
The manipulator of amount of deflection float design with matching is closed, high reliablity in real work, positioning clamping effect is good, serious forgiveness
Height, preferably realization functional objective.
Setting for hold-down mechanism utilizes compression by the cooperation between the compact heap and compression axis of hinged L shape
The up and down compact heap that realizes of axis is very convenient to the compression of workpiece.
Boss is set in block main body by compressing in centering, so as to limit the extreme position that compression axis moves downward
System；Simultaneously because compact heap stretches out center bridge, when compression axis moves upwards, when being more than certain position, compact heap can be encountered fixed
The heart compresses block main body, to limit the upper limit position of compression axis.
