The technical solution of the utility model is:
A kind of damping electric welding machine described in the utility model, include housing, be arranged on the circuit board of enclosure interior, it is characterized in that: between described circuit board and housing bottom, be provided with four longitudinal dampers, between circuit board and housing antetheca, be provided with two transverse dampers;
Wherein, described longitudinal damper includes upper end cover, bottom end cover and shock-absorption air bag; The upper end cover of described four longitudinal dampers is separately fixed at four jiaos of circuit board bottoms, the bottom end cover of described four longitudinal dampers is separately fixed at the position that housing bottom surface and upper end cover cooperatively interact, the sidewall bottom of described upper end cover is embedded in bottom end cover, the inner cavity that forms of the two hollow; In described cavity, be provided with shock-absorption air bag;
Described transverse damper is the damping spring of a horizontal positioned, and described transverse damper one end and circuit board are fixed, and the other end and housing antetheca inner side are fixing.
The utility model is for improving from the vibration problems in circuit board level direction and vertical direction, both direction is realized bumper and absorbing shock by different flexible pieces, there is dough deformation in damper and transverse damper longitudinally when being subject to impacting, mild transition and then elimination are impacted, thereby slow down the vibrations of electric welding machine integral body.
Further, in damping electric welding machine described in the utility model, described shock-absorption air bag is provided with inflation inlet.
Further, in damping electric welding machine described in the utility model, between the upper end cover of described longitudinal damper and circuit board, all adopt screw to be connected between its bottom end cover and housing, firmly locking.
Further, in damping electric welding machine described in the utility model, the described parallel and symmetrical both sides that are arranged on circuit board front end of two transverse dampers, guarantee that stressed buffering is in poised state, prevent circuit board unbalance stress and occur tilting.
The beneficial effects of the utility model are:
1, in the utility model, between circuit board and housing antetheca, bottom, be respectively arranged with transverse damper and longitudinal damper, the horizontal direction causing in can the buffer circuit plate course of work and the vibrations in vertical direction, thus slow down the vibrations of electric welding machine integral body.
2, the longitudinal damper in the utility model adopts inflatable shock-absorption air bag, under jerk effect, and the compressed generation distortion of gas in shock-absorption air bag, thus slow down jerk power; Transverse damper adopts damping spring, and making to be rigidly connected to become flexibly connects, and slows down largely jerk power, improves the stability that electric welding machine uses; And shock-absorption air bag have lightweight, the advantage of can repeated inflation using.
Accompanying drawing explanation
Fig. 1 is the structural representation of damping electric welding machine.
Fig. 2 is the cutaway view Amplified image of longitudinal damper.
The specific embodiment
Now by reference to the accompanying drawings the utility model is further described:
Shown in Fig. 1, a kind of damping electric welding machine described in the present embodiment, mainly includes housing 1, is arranged on the circuit board 2 of housing 1 inside.Between described circuit board 2 and housing 1 bottom, be provided with four longitudinal dampers 4, between circuit board 2 and housing 1 antetheca, be provided with two transverse dampers 3, and two described transverse dampers are parallel to each other and the symmetrical both sides that are arranged on circuit board front end.
Shown in Fig. 1, Fig. 2, described longitudinal damper 4 is demountable structure, includes upper end cover 41, bottom end cover 42 and shock-absorption air bag 43.The upper end cover 41 of described four longitudinal dampers 4 is separately fixed on four jiaos of the bottoms of circuit board 2, the bottom end cover 42 of described four longitudinal dampers 4 is separately fixed at the position that housing 1 bottom surface and upper end cover 41 cooperatively interact, and between upper end cover and circuit board, all adopt screw lock between bottom end cover and housing, guarantee the fastness of its connection.The sidewall bottom of described upper end cover 41 is embedded in bottom end cover 42, and the inner cavity that forms of the two hollow, is provided with shock-absorption air bag 43 in described cavity.Described transverse damper 3 is the damping spring of a horizontal positioned, and described transverse damper 3 one end and circuit board 2 are fixing, and the other end is resisted against on housing 1 antetheca inner side.
In the present embodiment, on described shock-absorption air bag 43, be also provided with inflation inlet 44, so that repeated inflation is used.During inflation, should be noted that gas in shock-absorption air bag 43 is difficult for excessive, prevent that the air bag damping effect that causes really up to the mark from declining.
The principle of this structure is: when circuit board 2 produces certain vibrations, in the horizontal direction, the advantage that performance spring flexible connects, provides a horizontal shock absorbing effect to circuit board 2 and housing 1 with the transverse damper 3 of horizontal setting; In vertical direction, upper end cover 41 absorbs from the energy of circuit board 2 vertical tremors and moves up and down thereupon simultaneously, and the shock-absorption air bag 43 that makes to be arranged in internal cavities is repeatedly squeezed and discharges, thus the jerk on alleviating longitudinally.The present embodiment is simple in structure, takes into account horizontal shock-absorbing and longitudinally damping, has good damping performance.
Specific embodiment described herein is illustrative principle of the present utility model and effect thereof only, but not for limiting the utility model.Any person skilled in the art scholar all can, under spirit of the present utility model and category, modify or change above-described embodiment.Therefore, have in technical field under in every case and conventionally know that the knowledgeable modifies or changes not departing from all equivalences that complete under spirit that the utility model discloses and technological thought, must be contained by claim of the present utility model.
