The specific embodiment

See also Fig. 1 and Fig. 4, the transmission mechanism 20 that reloads that is provided for the utility model one preferred embodiment, the transmission mechanism 20 that reloads is installed in an end of a bar feeder 10, bar feeder 10 includes a rotating shaft 12, and rotating shaft 12 has second cam 124 that one first cam 122 and is positioned at first cam, 122 belows.See also Fig. 1 and Fig. 2, the transmission mechanism 20 that reloads includes a drive unit 30, a fixed head 40, a portable plate 50, a continous action base 60 and a drivening piece 70.

Drive unit 30 has reduction box 34 that a motor 32, is fixed in motor 32 is connected reduction box 34 with one gear 36.

Fixed head 40 is fixed in bar feeder 10.The top of fixed head 40 has two slide rails 42 of being separated by a preset distance, and fixed head 40 is provided with a tooth bar 44 in addition between two slide rails 42.In addition, a side of fixed head 40 is installed with a holder 46 (as shown in Figure 1).

The top of portable plate 50 locks in the reduction box 34 of drive unit 30 admittedly, and the top of portable plate 50 has the protuberance 52 of a circle, is located at two slide rails 42 respectively and the below of portable plate 50 has two slide blocks, 54, two slide blocks 54.Portable plate 50 offers a perforation 56, the gear 36 of drive unit 30 pass perforation 56 and with tooth bar 44 engagement of fixed head 40.Gear 36 can be subjected to the driving of motor 32 and move forward and backward along tooth bar 44, and drives portable plate 50 synchronously, makes portable plate 50 see through two slide blocks 54 along two slide rails 42 and relative fixed plate 40 extreme position before is afterwards mobile between the extreme position with one.See also Fig. 4 and Fig. 6, a side of portable plate 50 has a roller 58, and roller 58 can roll along first cam 122 and second cam 124 of rotating shaft 12.When portable plate 50 when extreme position moves backward, roller 58 rolls along second cam 124, and drive rotating shaft 12 is rotated towards counterclockwise, promptly finish the action (as shown in Figure 3) of uncapping this moment, and when portable plate 50 when extreme position moves forward, roller 58 rolls along first cam 122, and drives rotating shaft 12 towards rotating clockwise, then finishes the action (as shown in Figure 5) of closing lid this moment.

Please cooperate and consult Fig. 7, continous action base 60 is installed in portable plate 50, and between a feed pipe 18 of portable plate 50 and bar feeder 10.Continous action base 60 utilizes an extension spring 62 to be connected with holder 46, and the bottom surface of continous action base 60 has a projection 64.

Drivening piece 70 is hubbed at the top of portable plate 50, and an end of drivening piece 70 has a hook part 72, as shown in Figure 2.

Via said structure, after the signature rod 16 of bar feeder 10 is sent bar into machined into and is finished, giving as security rod 16 can together take back remaining bar in the feed pipe 18 through the feed mechanism of bar feeder 10, and utilize a chuck remaining bar to be clamped (this is for existing structure, do not give unnecessary details in this appearance), at this moment, motor 32 can rotate by beginning driven wheels 36, make portable plate 50 along two slide rails 42 backward extreme position move.In the process that portable plate 50 moves, the hook part 72 of drivening piece 70 can connect gives as security rod 16, make portable plate 50 drive signature rod 16 moves backward, the signature rod 16 of this moment can break away from bar, in order to finish the action of pulling out material, chuck then can unclamp bar, bar is slipped in the material collecting tank carry out follow-up processing.

Pawn rod 16 and arrive fixed point, portable plate 50 continues backward, and extreme position moves, drivening piece 70 can produce and pivot, make the hook part 72 of drivening piece 70 break away from signature rod 16, at this moment, the roller 58 of portable plate 50 can roll along second cam 124, rotate towards counterclockwise in order to drive rotating shaft 12, make rotating shaft 12 lift and finish the action of uncapping giving as security rod 16, as shown in Figure 3, the portable plate 50 of this moment promptly is positioned at the back extreme position.Then a bar to be processed can fall into feed pipe 18, see through a push rod will bar to be processed deliver to give as security excellent 16 front end after, and utilize chuck that bar to be processed is clamped, push rod can be got back to original position, and (this is existing structure, do not give unnecessary details in this appearance), at this moment, motor 32 can begin driven wheel 36 again and rotate, make portable plate 50 along two slide rails 42 forward extreme position move.In portable plate 50 process that extreme position moves forward, this moment, 58 on the roller of portable plate 50 can roll along first cam 122, in order to drive rotating shaft 12 towards rotating clockwise, make rotating shaft 12 action of closing lid can be put down and be finished to signature excellent 16, as shown in Figure 5, at this moment, the protuberance 52 of portable plate 50 can push against the projection 64 of continous action base 60, as shown in Figure 8, continous action base 60 is moved forward, and continous action base 60 is when moving forward, and promote to give as security rod 16 and move forward and combine with bar, in order to finish the action of inserting material, the portable plate 50 of this moment promptly is positioned at preceding extreme position, thus, bar can be sent into lathe again and processes.

By this, structure of the present utility model is quite simple, utilizes moving back and forth of portable plate, can drive apace to give as security the action that rod pulls out material and inserts material, if wherein have member to be damaged, it is also quite convenient to keep in repair, in order to increase the convenience in the operation.
