Description

The thread generator automatic feeding

The utility model relates to the parts of a kind of thread generator, particularly a kind of thread generator.

Traditional thread generator pay-off, be provided with one and can make upper and lower reciprocating feedboard, its desirable situation is, when feedboard moves back and forth, bunchiness can be carried and arrive push out one to set the milling in the dental lamina of board without milling tooth screw round bar, by milling dental lamina this round bar is milled out screw thread again, waits that the screw that is milled with screw thread sends the thread generator pay-off, its feeding and mill tooth and have following shortcoming:

1, because pay-off vertically is built up on the board, when feedboard moved upward, bunchiness was carried and often once falling in a large number without the screw round bar that mills tooth of arriving milled in the dental lamina, so that influenced it and mill the tooth process, can't take into account the integrality of each screw, increase the defect rate that mills tooth;

2, vertically be built up on the board owing to pay-off, when feedboard moves downward, if the time mismatch that arrives with the conveying of screw round bar, this feedboard can directly impact the screw round bar, not only easily cause the damage of feedboard, and therefore this round bar also can wreck reduction productivity ratio.

The purpose of this utility model is that a kind of improved thread generator automatic feeding will be provided, and it can reduce the defect rate of product, improves milling tooth quality, increase output, the life-span of reducing fault rate and prolongation dental lamina of screw.

Utility model is achieved in that automatic feeding establishes a pusher and mainly be made up of a holder, a sliding seat and a pushing plate, establish a spring between holder and sliding seat, establish a lever arm on the sliding seat, one end of lever arm is connected on the sliding seat with a movable axis, the other end then is located on the circular shaft, on sliding seat, establish a contiguous block, the rear portion of contiguous block is provided with circular hole, circular hole and connecting rod are connected to each other and can affect mutually, and a fixed head with suitable gradient is established in the bottom of holder; One pallet arrangement is mainly by a pedestal, and a dental lamina and a supporting plate constitute; Pusher in the above-mentioned member is to be about 30 a ° angle to be built up on the board of thread generator, the top of set supporting plate is located on the pedestal with a rotating shaft in the pallet arrangement, its bottom is to be a suitable inclined-plane and can to fit mutually with pedestal, establish a spring between supporting plate and pedestal, the elastic force of spring can suitably outwards eject supporting plate.

Pushing plate of the present utility model down push out a screw round bar and upwards contracted again after, but the mat supporting plate is with feed track outlet sealing, can guarantee once only to send a screw round bar, improve the quality of milling tooth, also avoid a large amount of screw round bars to fall into dental lamina is damaged; Set up because pusher is 30 ° of angles of constraint, when pushing plate pushes the screw round bar downwards, can avoid to protect pushing plate and screw round bar injury-free, increase the service life because of the direct positive impact that is produced that contacts.Reduce coefficient of losses; Simple in structure, be easy to make; The screw round bar cooperates automatic feeding, can make the time of sending into accurate and stable, during simultaneously because of incision one corner mouth is arranged, and can reach the purpose of time delay, improves the screw-tjread system manufacturing accuracy; Can reduce the defect rate of product, increase the life-span of dental lamina.

The concrete structure of utility model is provided by following examples and accompanying drawing thereof.

Fig. 9 is another action schematic diagram of Fig. 1 structure.

With reference to Fig. 1, the thread generator automatic feeding includes a pusher 1 and a pallet arrangement 2, pusher 1 is slightly to be 30 ° angle to be installed on the board A, below board A, establish a belt pulley A1, the axle center A11 of belt pulley A1 drives a cam A2 disposed thereon and rotates, and the reciprocating motion about driving a reciprocating apparatus A5 simultaneously and doing, the tail end of reciprocating apparatus A5 is established a dental lamina seat A51, so dental lamina seat A51 can be along with the motion of reciprocating apparatus do reciprocating action in the set chute of board, below cam A2, establish a toggle-action lever A3, because the bottom surface of cam A2 is an inclined-plane, when contacting when its rotation and with toggle-action lever, can drive toggle-action lever A3 and do lever motion with its axle center A31, establish a connecting rod A4 at the other end of toggle-action lever A3, the top of connecting rod A4 is connected the pusher 1 of thread generator automatic feeding, the feed track C of a screw round bar is established in pusher 1 below, mat one is arranged on the vibration of feed track C front end and arranges machine D, screw round bar B can be arranged identical direction, and send among the feed track C.

With reference to Fig. 2,3,4, pusher 1 is by holder 11, sliding seat 12, pushing plate 13 is formed, 12 of holder 11 and sliding seats are established a spring 14, establish a lever arm 15 on the sliding seat 12, one end of lever arm 15 is connected in sliding seat 12 by a movable axis 16, its other end is arranged in a circular shaft 17, establish a contiguous block 18 on the sliding seat 12, there is circular hole 19 at the rear portion of contiguous block 18, circular hole 19 and connecting rod A4 shown in Figure 1 are connected to each other and affect mutually, a fixed head 111 with suitable gradient is established in the bottom of holder 11, and the gradient of fixed head 111 is to cooperate the gradient of feed track C shown in Figure 1 and establish.

With reference to Fig. 5,6,7, pallet arrangement 2 is made of a pedestal 21, a dental lamina 22, a supporting plate 23, supporting plate 23 is elasticity, and supporting plate 23 tops are located on the pedestal 21 by a rotating shaft 24, and its bottom is a suitable inclined-plane and can fits mutually with pedestal 21, establish a spring 25 at supporting

plate

23 and 21 of pedestals, utilize the elastic force of spring 25, supporting plate 23 suitably outwards can be ejected nature, when supporting plate 23 was squeezed, its inclined-plane, bottom can be fitted on the pedestal.

With reference to Fig. 8, screw round bar B is in sending into feed track C continually, axle center A11 is driven and is rotated by belt pulley A1 (as Fig. 1), when the inclined-plane of cam A2 bottom contacts with toggle-action lever A3, the pushing plate 13 of pusher 1 is to be one with feed track C closed state, pushing plate 13 is to be compressed on the supporting plate 23 simultaneously, and it inwardly is fitted on the pedestal 21.

With reference to Fig. 9, when the protuberance of cam A2 bottom contacts with crank A3 and when suppressing the end of bent tenon bar A3, can make toggle-action lever A3 do lever motion with its axle center A31, and its other end is upturned, then driving connecting rod A4 moves upward, driving sliding seat 12 simultaneously upwards slides, pushing plate 13 is to feed track C opening, supporting plate 23 discharges simultaneously, and therefore supporting plate 23 outwards ejects and be blocked in the opening part of feed track C, and this moment, the set dental lamina seat A51 of tail end of reciprocating apparatus A5 had been advanced to sliding tray A6 foremost, finish the tooth process of milling of a screw round bar B, after treating this screw that has milled tooth sent board, be returned to the state as Fig. 8 again, this pushes a screw round bar, it is dropped at the dental lamina seat, mat dental lamina and dental lamina seat slide forward, and with set screw thread on dental lamina and the dental lamina seat, the ganoid screw round bar of script can be milled out predetermined required screw thread, at this moment, be to be state as shown in Figure 9, so go round and begin again, can repeat to mill the program of tooth.
