A kind of car seat headrest assembling fixture
Technical field
The utility model relates to the assembly technique of automotive seat.
Background technology
At present, when car seat headrest is assembled, be to rest the head on earlier after foam framework inserts two fixed orifices, manpower is aimed at foam surface with the reverse side of its headrest covering, and bimanual four instigate strength with a little be inserted in of its covering, and finger is firmly very big, tired easily, operator's labour intensity is big like this, and the prolongation that efficient on duty can be in time and reducing, and does not meet human engineering demand and balanced production.
Summary of the invention
The purpose of this utility model is the problem that exists at prior art, proposes a kind of laborsaving, fast speed car seat headrest assembly method and anchor clamps, reduces operator's labour intensity, reduces fatigue exponent, and the productive temp time is accelerated.
The technical scheme that its technical matters that solves the utility model adopts is:
A kind of car seat headrest assembling fixture comprises working cabined, vacuum pump, double-acting cylinder, shaping bench board, copper sheathing, sealing bag, slide block, linear bearing, pressing plate, guide rod, electric control box.
Described vacuum pump and double-acting cylinder are installed in the working cabined, and electric control box is installed in the working cabined outside, and the shaping bench board is installed on the working cabined.
Described shaping bench board is provided with the guide rod of a pair of hollow, and the mesopore size of guide rod conforms to the diameter of head rest pole, to make things convenient for the insertion of head rest pole.The lower end of guide rod is connected with vacuum pump, by linear bearing slide block is installed on the guide rod, and the lower port of sealing bag compresses by pressing plate and rubber seal and is connected the slide block periphery, and slide block is connected with the double-acting cylinder of below.
Advantage of the present utility model is as follows:
1, by vacuum compression, after the employing packing cloth compresses highdensity foam its monnolithic case is diminished, its covering is convenient to easily be inserted in greater than the profile of foam, and is quick like this, laborsaving.
2, packing cloth wraps in the outside of foam, makes not direct contact of the inboard of covering and foam surface, has reduced the friction between them to a great extent, makes the covering cover fashionable easily.
3, after covering is put, turn off vacuum, the just automatic change of foam is full of covering greatly, can amplify the characteristic of dwindling according to foam, considers that the different work steps of assembling need carry out rational and efficient use with its characteristic.
4, be inserted at covering and by cylinder its headrest assembly ejected after finishing, made full use of automation, artificial mode of firmly being inserted in downwards is thought of as cylinder upwards ejects, aspect human engineering, reduced operator's labour intensity in this link.
Description of drawings
Fig. 1 is the structural representation of assembling fixture;
Fig. 2 is the part sectional view of Fig. 1.
Among the figure: 1, lower margin 2, working cabined 3, rotary-vane vaccum pump 4, double-acting cylinder 5, shaping bench board 6, copper sheathing 7, packing cloth 8, plastic jacket 9, slide block 10, linear bearing 11, pressing plate 12, guide rod 13, permanent seat 14, air cylinder fixed plate 15, electric control box
The specific embodiment
Framing member Fig. 1 and Fig. 2 of anchor clamps are connected 1 dozen of expansion bolt of lower margin with ground, again with working cabined 2 welding; Rotary-vane vaccum pump 3 is inserted in the working cabined 2; Shaping bench board 5, electric control box 15 adopt bolted connection with working cabined; Air cylinder fixed plate 14 is fixed on the working cabined 2 by bolted connection, double-acting cylinder 4 is fixed on air cylinder fixed plate 14 times, permanent seat 13 is installed on the air cylinder fixed plate 14, the guide rod 12 of hollow is installed on the permanent seat 13, the gap connects the back with ending a screw lock, the lower end of guide rod 12 has gas-tpe fitting to be connected with rotary-vane vaccum pump 3 by tracheae, by linear bearing 10 slide block 9 is installed on the guide rod 12, the lower port of sealing bag 7 compresses by pressing plate 11 and rubber seal and is connected slide block 9 peripheries, slide block 9 is connected with the double-acting cylinder 4 of below, promotes the slide block up-and-down movement.When not using, plastic jacket 8 is stamped in the upper end of guide rod 12.Copper sheathing 6 is embedded on the shaping bench board 5, makes head rest pole insert copper sheathing and plays fixedly headrest effect, is convenient to shaping.
Assembly method:
(1) foam framework of will resting the head on earlier inserts in the fixed orifice of anchor clamps;
(2) wrap headrest foam on the headrest foam framework from the bottom up with the sealing bag that is fixed on the upper end open on the anchor clamps slide block, packing cloth pulled on encase the headrest foam, open vacuum pump and take out the interior air of sealing bag, the foam of will resting the head under atmospheric effect compresses, and it is diminished;
(3) covering with chair headrest is set on the sealing bag from the top down, turns off vacuum again, and the headrest foam is full of covering after becoming greatly automatically;
(4) slide block by fixing seal bag on the double-acting cylinder pulling anchor clamps of anchor clamps moves downward, and sealing bag is pulled out from covering, finishes the headrest assembling.
