Embodiment 1
The straight spring automatic mounting machine device of Upholstered sofa seat frame, including rack 1, horizontal movement unit 2, oblique angle direction moving cell 3,
Hook compresses and nailing unit 4.
Spring installation function is realized：Spring installation function is mainly matched by horizontal movement unit 2 and oblique angle direction moving cell 3
It closes and completes, according to design, oblique angle direction moving cell 3 is mounted in rack 1, and movement driving cylinder is by installing ears or side handles of a utensil installation
In rack, the piston of cylinder drives entire angular movement unit linear bearing 11 by axis pin 13, along with horizontal direction at
The linear axis movement at 75 ° of angles.The moving slide block 8 and horizontal guide rail mounting bracket 10 of horizontal movement unit 2 coordinate, and cylinder 14 acts,
Moving slide block 8 and the opposite sliding of horizontal guide rail mounting bracket 10, complete the extension action of spring.The movement of oblique angle direction drives horizontal fortune
The global facility of moving cell 2 is moved also along with horizontal direction along the direction at 75 ° of angles.Horizontal movement and from the horizontal by
The movement of 75 ° of angles, the common elongation for completing spring and hook-hanging motion.Action process describes：
The first step：On the hook that straight spring one end is hung over to the seat frame one side for having fixed hook, the other end of spring（In Fig. 6
35 pointed locations）It hangs on the hook 7 on horizontal movement unit 2, preparation is completed；
Second step：Start button is pressed, the cylinder piston of angular movement unit stretches out, the non-hook end of spring is raised, it is made
Higher than hook height；
Third walks：Horizontal air cylinder piston stretches out, and spring is moved to the length that can be suspended on hook.
4th step：Angular movement unit cylinder piston is retracted, and spring, which drops to hook 32, can catch on the position of spring；
5th step：2 cylinders retract of horizontal movement unit, spring retraction are hung on hook 32, and hook-hanging motion is completed.Horizontal movement
The cylinder piston return course of unit 2, hook 7 can rotate in the opposite direction, and return stroke is avoided to be suspended on spring.
Hook compresses and nailing unit 4：Spring carrier arm compresses and nailing unit is along transverse movement, when system sends out compression
And after nailing order, hook compresses and nailing unit 4 will be under the action of stepper motor 23 and 27, and band moving gear is along straight line
Rack 19 moves.In motion process, the position of monitoring switch detection spring hook（Element 24 in such as figure, each point of seat frame both sides
Portion 4-7 are differed）, then control operating mechanism and take hold-down mechanism to hook（24 and 32 in such as figure）Top, cylinder movement will
Hook pressing, continues to move to, and further fixes hook by the nailing gun in hook compression and nailing unit 4, prevents
Spring falls off.Referring to Fig. 5, hold-down mechanism principles and methods：But hook compresses and nailing unit 4 moves to after linking up with position and stops automatically
Only, 21 piston of cylinder stretches out, and the hold-down mechanism conduit dress arm shaft 32 that rotates rotates by a certain angle, and compresses hook（24 Hes in figure
32）, then drive nailing gun to be moved to hook position, complete set action.
Hook 7 laterally adjusts design：The different installation width requirement of spring is designed according to sofa seat frame, it can be by adjusting
Adjustable hanging-hook installing frame 6 on spring carrier arm mechanism installation aluminium alloy frame 5 obtains position and is adjusted.
