The auxiliary fixing device has the advantages that the structure is simple, and the positioning is accurate, and the sealing performance is good.
Description
Technical field
The present invention relates to damper manufacturing technology field, particularly relate to a kind of automobile absorber inflation fixing-aid device.
Background technology
In automobile industry standard, some explanations are carried out for the technical conditions of vehicle shock absorber and Bench test methods, wherein make as given a definition about " inflating force ": for gas-filled shock absorber, when piston is in the centre position of stroke, the gas power acted on piston rod is inflating force.But, when carrying out air test to piston lever of reducer for automobile, need effectively to fix damper.
Summary of the invention
The object of the invention is the technological deficiency for existing in prior art, and a kind of servicing unit that can be fixed it when automobile absorber carries out air test is provided.
The technical scheme adopted for realizing object of the present invention is: a kind of automobile absorber inflation fixing-aid device, it is characterized in that comprising base plate and with the upper location-plate that base plate be arranged in parallel, be fixed connection by support column between the two; Described base plate being provided with lower location-plate, base plate being fixed with the joint pin for supporting described lower location-plate; Described upper plate being provided with upper junction plate, upper plate being fixed with the joint pin for supporting described upper junction plate; Described upper location-plate and lower location-plate have the locating hole for positioning damper; Described upper junction plate is provided with locking nut, and the below of described locking nut is connected with the inflation compact heap that bottom is provided with cavity, and the position that described inflation compact heap contacts with damper is provided with the adhesive tape for sealing; Described inflation compact heap has vertical slide opening, and described slide opening is equipped with the inverted T shape traveller with described slide opening sliding connection; The contact point of described traveller and described inflation compact heap is provided with spring; The side of described inflation compact heap is provided with the charging connector being connected to described cavity.
Further, the side of described locking nut is provided with the lock-screw of locking described traveller for horizontal direction.
Operation principle of the present invention and beneficial effect are: the bottom suspension ring end of damper is located by lower location-plate, and its upper end is located by upper location-plate.Gases at high pressure are entered in the cavity of inflation compact heap by charging connector.Because adhesive tape sealing is passed through on the top of inflation compact heap and damper, gases at high pressure extruding traveller moves upward, and spring is compressed; Meanwhile, gases at high pressure apply downward pressure to the damper (liquid container) below inflation compact heap, thus damper is fixedly clamped.Structure of the present invention is simple, and accurate positioning, good airproof performance, can carry out air test to piston lever of reducer fast and effectively.
Accompanying drawing explanation
Figure 1 shows that the structural representation of a kind of automobile absorber inflation fixing-aid device;
Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is described in further detail.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Embodiment:
Be illustrated in figure 1 a kind of automobile absorber inflation fixing-aid device, a kind of automobile absorber inflation fixing-aid device, it is characterized in that comprising base plate 1 and with the upper location-plate 5 that base plate 1 be arranged in parallel, be fixed connection by support column 4 between the two; Undertaken fastening by screw 2 between base plate 1 and support column 4, upper location-plate 5 is fastening by bolt 6 with support column 4; Described base plate 1 being provided with lower location-plate 3, base plate 1 being fixed with the joint pin for supporting described lower location-plate 3; Described upper plate 5 being provided with upper junction plate 14, upper plate 5 being fixed with the joint pin 16 for supporting described upper junction plate 14, joint pin 16 and upper junction plate 14 are undertaken fastening by hex nut 13; Described upper location-plate 5 and lower location-plate 3 have the locating hole for positioning damper, and the lower end suspension ring of damper are positioned by lower location-plate 3, and the top of upper location-plate 5 pairs of dampers positions; Described upper junction plate 14 is provided with locking nut 11, the below of described locking nut is connected with the inflation compact heap 15 that bottom is provided with cavity, the position that inflation compact heap 15 contacts with damper is provided with the adhesive tape 7 for sealing, described inflation compact heap 15 has vertical slide opening 9, and described slide opening 9 is equipped with the inverted T shape traveller 10 with the sliding connection of described slide opening 9; Described traveller 10 is provided with spring 8 with the contact point of described inflation compact heap 15; The side of described inflation compact heap 15 is provided with the charging connector 17 being connected to described cavity.
Further, the side of described locking nut 11 is provided with the lock-screw 12 of locking described traveller 10 for horizontal direction, and lock-screw 12 is preferably socket cap screw.
The course of work: the bottom suspension ring end of damper is located by lower location-plate 3, and its upper end is located by upper location-plate 5.Gases at high pressure are entered in the cavity of inflation compact heap 15 by charging connector 17.Because inflation compact heap 15 and the top of damper pass through adhesive tape sealing, gases at high pressure extruding traveller 10 moves upward, and spring 8 is compressed; The upper end of damper is liquid container, and gases at high pressure apply downward pressure to the damper (liquid container) below inflation compact heap simultaneously, thus damper is fixedly clamped.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
