Summary of the invention
The utility model provides a kind of simple in structure, the depressing cam assembly of control knitting needle with intermediateness.
A kind of depressing cam assembly, comprise the depressing cam briquet, the depressing cam briquet is made of base plate and vertical base head, the base head connects depressing cam and following depressing cam respectively, base plate both sides up and down is respectively equipped with depressing cam take-up housing and following pressing cam block seat, following pressing cam block seat afterbody connects the cylinder that has push rod, top rod driving depressing cam briquet integral body seesaws, the movement position that the top rod driving depressing cam briquet integral body of described cylinder seesaws is divided into three operating points and is respectively outermost end, intermediate ends, inner terminal, three operating points that top rod driving depressing cam briquet by cylinder constitutes, also just formed from the inner terminal to the intermediate ends, and two kinds of duties of outermost end have increased the colored type of footwear machine, the difficulty of weaving that raising can adapt to.
Described depressing cam and the following depressing cam gone up is provided with the up-down drive device that driving depressing cam regulating block moves up and down by the depressing cam regulating block base head that is connected in the base head.Described up-down drive device comprises the centre bore of being located in the base head, and first back-moving spring, the transverse screw that connects the depressing cam regulating block, the top of airtight cooperation centre bore internal diameter are installed in the centre bore successively; The airtight connection end cap in described centre bore outer face, be provided with pore in the end cap by connecting the tracheae of air pump, being communicated with centre bore makes centre bore become an air cavity, thus by connecting the tracheae of air pump, drive the top and press down transverse screw, and then realize that the depressing cam regulating block moves downward, and reset by first back-moving spring and to realize that the depressing cam regulating block moves upward.
Be provided with two air chambers in the described cylinder, be respectively first air chamber and second air chamber, first push rod, subluxation inductor, adjusting screw(rod) are installed in first air chamber successively; Second push rod is installed in second air chamber.Described go up depressing cam take-up housing upper surface respectively before and after connecting band the limited block and the position-limitting pin of spacing screw rod are arranged, position-limitting pin connects the base head by second back-moving spring.This kind air cylinder structure at first moves to the centre position by first push rod promotion depressing cam briquet that air pump drives in first air chamber from inner terminal, and after putting in place by subluxation inductor induction, realize knitting needle meta duty, thereafter the promotion of second push rod in second air chamber depressing cam briquet to outermost position, is realized the high-order duty of knitting needle from middle end motion.
Described base plate both sides up and down connects upward depressing cam take-up housing and following pressing cam block seat by last linear slider, following linear slider respectively, improves the stability that the depressing cam briquet seesaws.
The utility model is by three operating points of the top rod driving depressing cam briquet formation of cylinder, realize intermediate ends and outermost end duty that two kinds of duties are the depressing cam briquet, increased the colored type of footwear machine, the scope of difficulty of weaving that raising can adapt to and cross directional stretch length.
Description of drawings
Be illustrated in figure 1 as the utility model depressing cam assembly perspective view;
Be illustrated in figure 2 as the utility model depressing cam assembly and blow the mounting structure schematic diagram.
The specific embodiment
A kind of as shown in Figure 1, 2 depressing cam assembly, comprise depressing cam briquet 10, depressing cam briquet 10 is made of base plate 4 and vertical base head, the base head connects depressing cam 11 and following depressing cam 6 respectively, base plate connects upward depressing cam take-up housing 3 and following pressing cam block seat 2 by last linear slider 12, following linear slider 13 respectively in both sides about in the of 4, last depressing cam take-up housing 3 upper surfaces respectively before and after connecting band the limited block 5 and the position-limitting pin 7 of spacing screw rod 25 are arranged, position-limitting pin 7 connects the base heads by second back-moving spring 8.Following pressing cam block seat 2 afterbodys connect the cylinder 1 that has push rod, top rod driving depressing cam briquet 10 integral body seesaw, and the movement position that top rod driving depressing cam briquet 10 integral body of cylinder 1 seesaw is divided into three operating points and is respectively outermost end, intermediate ends, inner terminal.
