Abstract
The invention relates to a riveting and machining device for a piston rod sub-assembly component in an automobile damper assembly, in particular to a limiting and fixing sleeve riveting device. The limiting and fixing sleeve riveting device comprises a supporting frame, wherein a positioning seat is arranged at the bottom of the supporting frame. A supporting plate is arranged on the supporting frame. The limiting and fixing sleeve riveting device further comprises a tool body. A connecting sleeve is arranged on the upper portion of the tool body. A material returning rod is arranged in a cavity in the center of the tool body and the center of the connecting sleeve. A pre-tightening bolt is connected to the upper portion of the material returning rod. The pre-tightening bolt is connected to a material returning spring in a sleeved mode. The material returning spring can make the material returning rod and the pre-tightening bolt move vertically in the cavity in the center of the tool body and the center of the connecting sleeve when stretching out and drawing back. A riveting head is arranged at the bottom of the tool body. The limiting and fixing sleeve riveting device has the advantages that a limiting and fixing sleeve is fixed to a piston rod through a riveting process, as a result, a press fitting process can be omitted, electric energy is saved, and cost is reduced.
Description
Technical field
The present invention relates to piston rod sub-unit parts riveting processing device in a kind of automobile absorber assembly.
Background technology
The develop rapidly of car industry has driven greatly developing of car industry parts and components supplier.Along with increasing of kinds of automobile, the shape of automobile absorber also, is upgrading, is being improved in the development and change along with automobile industry.Along with the variation of damper, damper internal structure also changes along with the variation of damper.Such change is in order to meet the demand of people to automotive performance.To damper, it is a qualitative raising.To producing the producer of damper, it is a test, because each equipment of producing the producer of damper is roughly identical, and flourish along with car industry, the variation of automobile product, the producer that manufactures so automobile absorber also must grow with each passing hour, and catches up with the step of car industry development.In the production process of automobile absorber, relate to multiple processing technology.These techniques are also constantly being improved, are being improved.In order meeting, to update technique, just must to design the processing unit (plant) making new advances, meet the specification requirement of damper, guarantee the quality of damper simultaneously.Can boost productivity again, reduce costs.
Present piston rod sub-unit, is by spot-welding technology, and limit fixed sleeve is welded on piston rod.Between limit fixed sleeve and piston rod, can be matched in clearance, can be also interference fit.If interference fit needs increase to press-fit together operation; If matched in clearance easily produces and splashes when welding.
Summary of the invention
The invention provides a kind of limit fixed sleeve riveting set, realize and once having press-fited, reduced and press-fited operation, saved electric energy, reduced cost.
In order to achieve the above object, the technical solution used in the present invention is:
A kind of limit fixed sleeve riveting set, it is characterized in that: comprise that bottom is provided with the bracing frame of positioning seat, bracing frame is provided with supporting disk, also comprise frock body, frock body top is provided with adapter sleeve, in the cavity at frock body and adapter sleeve center, be provided with material returned bar, material returned bar top connects pretension bolt, pretension bolt is socketed on material returned spring, when material returned telescopic spring, can make material returned bar and pretension bolt move up and down in the cavity at frock body and adapter sleeve center, in the bottom of frock body, also be provided with riveted joint.
The invention has the beneficial effects as follows: limit fixed sleeve is fixed on piston rod by riveting process, can reduces and press-fit operation, and saved electric energy, reduced cost.
Accompanying drawing explanation
Fig. 1 is piston rod sub-unit contour structures schematic diagram.
Fig. 2 is structural representation of the present invention.
In figure: 1. piston rod; 2. limit fixed sleeve; 3. positioning seat; 4. bracing frame; 5. supporting disk; 6. riveted joint; 7. frock body; 8. material returned bar; 9. packing ring; 10. pretension bolt; 11. material returned springs; 12. adapter sleeves.
The specific embodiment
As shown in Figure 1, piston rod sub-unit is comprised of piston rod 1 and limit fixed sleeve 2.By riveted joint, process, limit fixed sleeve 2 is fixed on the certain position of piston rod 1.And guarantee the intensity of product needed.
Referring to accompanying drawing 2, the present invention includes the bracing frame 4 that bottom is provided with positioning seat 3, bracing frame 4 is provided with supporting disk 5, also comprise frock body 7, frock body 7 tops are provided with adapter sleeve 12, in the cavity at frock body 7 and adapter sleeve 12 centers, be provided with material returned bar 8, material returned bar 8 tops connect pretension bolt 10, pretension bolt 10 is socketed on material returned spring 11, when material returned spring 11 is flexible, can make material returned bar 8 and pretension bolt 10 move up and down in the cavity at frock body 7 and adapter sleeve 12 centers, in the bottom of frock body 7, also be provided with riveted joint 6.
Before use, first according to the diameter of limit fixed sleeve 2, choose corresponding riveted joint 6, guarantee that after limit fixed sleeve 2 riveted joints, one end of limit fixed sleeve 2 is stuck in the groove on piston rod 1 completely.Then according to the length of piston rod 1, choose corresponding positioning seat 3 and material returned bar 8.
During use, adapter sleeve 12 and press device are connected, and mix up the position of travel switch (not shown).Bracing frame 4 is arranged on the work top of equipment.Operate as follows: limit fixed sleeve 2 is through on piston rod 1, then piston rod 1 is also placed on piston rod 1 one end on positioning seat 3 through supporting disk 5, supporting disk 5 is placed on bracing frame 4.Starting pressure equipment, riveted joint 6 moves down limit fixed sleeve 2 processing of closing up.By control, pressing down the riveted joint that stroke completes limit fixed sleeve 2 processes.In the descending process of riveted joint 6, material returned bar 8 is wanted end in contact on first and piston rod 1, and material returned spring 11 is compressed.After travel switch contact, riveted joint 6 returns, and completes riveted joint processing.
