The third guide rail is fixed to the frame in front of the double-station punching mechanism.

[0007] The feeding mechanism and the double-station transfer mechanism cooperate so that there are always two pulley blanks waiting to be transferred on the two placement seats, and each time the double-station transfer mechanism moves back and forth, the two pulley blanks are transferred to the double-station punching mechanism, and the two processed pulley blanks are moved out of the double-station punching mechanism at the same time;

[0008] The double-station punching mechanism includes two punching seats and punching devices corresponding to the two punching seats. The two punching seats have placement holes corresponding to the pulley blanks. The punching device includes two drilling machines fixed on the lifting platform. The drill rods of the two drilling machines are respectively set corresponding to the positions of the two punching seats.

[0011] Furthermore, the spacing between the two placement seats is kept corresponding to the spacing between the two punching seats to meet the structural design requirements of the double-station transfer mechanism.

[0012] Furthermore, the two placement seats and the two punching seats are located on the same straight line.

[0013] Furthermore, the mounting seat is connected to the lifting seat by a lifting cylinder, and a second screw device driven by a second servo motor is provided on the second guide rail. The second guide rail is also provided with a long slot, and the lifting seat is slidably connected to the second guide rail and connected to the second screw device.

DETAILED DESCRIPTION

[0030] The technical solution of the present invention will be further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0031] Combine Figure 1-6 As shown, an automated pulley continuous punching device includes a frame 1 and a feeding mechanism 100, a double-station transfer mechanism 200 and a double-station punching mechanism 300 arranged on the frame 1;

[0032] The feeding mechanism 100 includes a first guide rail 101 fixed to one side of the frame 1, a first clamp 102 that can move left and right along the first guide rail 101 and can be extended and retracted forward and backward, a first driving mechanism that drives the first clamp 102 to move, and two placement seats 103 arranged in front of the first guide rail 101. A workpiece input mechanism is also provided in front of the first guide rail 101 on one side of the two placement seats 103;

[0033] When a pulley blank is input to the end of the workpiece input mechanism, the first clamp 102 is located at a position corresponding to the pulley blank, the first clamp 102 extends and clamps the pulley blank, and then moves toward the placement seat 103 under the drive of the first driving mechanism, places the pulley blank on one placement seat 103, and then the first clamp 102 retracts and resets; repeating the above action, the first clamp 102 places the second pulley blank on the other placement seat 103, and then waits for the double-station transfer mechanism 200 to transfer the two pulley blanks to the bottom of the double-station punching mechanism 300;

[0034] The double-station transfer mechanism 200 includes two pairs of second clamps 201, a mounting base 202, a lifting base 203, a second guide rail 204, and a third guide rail 205. The two pairs of second clamps 201 are respectively telescopically connected to the mounting base 202. The mounting base 202 is lifted and lowered on the lifting base 203. The lifting base 203 is connected to the second guide rail 204 for left-right movement. The second guide rail 204 is connected to the third guide rail 205 for forward and backward movement. The third guide rail 205 is fixed to the frame 1 in front of the double-station punching mechanism 300.

[0035] After the lifting seat 203 of the double-station transfer mechanism 200 moves once toward the feeding mechanism 100, a pair of second clamps 201 are located at corresponding positions of the two placement seats 103, and the lifting seat 203 drives the mounting seat 202 to move downward. The pair of second clamps 201 extend and clamp the two pulley blanks respectively located on the corresponding placement seats 103, then the second clamps 201 retract, the mounting seat 202 rises, and the lifting seat 203 moves toward the double-station punching mechanism 300 to transfer the two pulley blanks to the double-station punching mechanism 300; at this time, the other pair of second clamps 201 also performs corresponding actions to move the two processed pulley blanks out of the double-station punching mechanism 300;

[0036] The feeding mechanism 100 and the double-station transfer mechanism 200 cooperate so that there are always two pulley blanks waiting to be transferred on the two placement seats 103, and each time the double-station transfer mechanism 200 moves back and forth, the two pulley blanks are transferred to the double-station punching mechanism 300, and the two processed pulley blanks are moved out of the double-station punching mechanism 300, so as to realize continuous feeding and improve the processing rhythm.

[0037] The double-station punching mechanism 300 includes two punching seats 301 and punching devices corresponding to the two punching seats 301. The two punching seats 301 have placement holes 302 corresponding to the pulley blanks. The punching device includes two drills 304 fixed on a lifting platform 303. The drill rods of the two drills 304 are respectively arranged corresponding to the positions of the two punching seats 301. The lifting platform 303 is lifted and connected to the column 305. The column 305 is fixed to the rear of the frame 1. The two punching seats 301 are arranged between the column 305 and the third guide rail 205.

[0038] After the double-station transfer mechanism 200 places the two pulley blanks on the two punching seats 301, the two punching devices move downward and punch holes in the two pulley blanks. After punching is completed, the two punching devices are reset. At this time, a pair of second clamps 201 of the double-station transfer mechanism 200 clamp the pulley blanks from the placement seat 103, and the other pair of second clamps 201 also performs the same action and takes the two punched pulley blanks out from the punching seat 301.

[0039] The beneficial effects of the above structure are: a compact and reasonable layout; the position design of the feeding mechanism 100, the double-station transfer mechanism 200, and the double-station punching mechanism 300 shortens the distance between feeding and workpiece transfer, which is conducive to improving the processing cycle and saving the floor space of the entire device;

[0040] The design of the double-station transfer mechanism 200 and the double-station punching mechanism 300 enables the equipment to drill holes in two pulley blanks at the same time. Together with the double-station pulley hole finishing equipment, the two devices can be combined into a smooth double-station production line, which can effectively improve production efficiency.

[0041] The structural design of the double-station transfer mechanism 200 allows it to simultaneously take into account the input and output of the pulley blank on the double-station punching mechanism 300, thereby further simplifying the structure of the equipment and improving the processing cycle;

[0042] Taking into account that the punching of the double-station punching mechanism 300 takes a long time, the feeding mechanism 100 in this technical solution is a single clamp design, which places the two pulley blanks on the two placement seats 103 in turn. On the one hand, it can save the manufacturing cost of the equipment, and on the other hand, it can cooperate with the pulley blank conveying mechanism to feed the pulley blanks in sequence.

[0043] Specifically, such as Figure 3 As shown, the placement seats 103 are two round tables, and the two placement seats 103 are fixed in front of the first guide rail 101 through a fixing frame 104.

The first clamp 102 is connected to the top of the slider 106 through a cylinder telescopic connection. The slider 106 is slidably connected to the first guide rail 101 and is connected to the screw through the long groove. This structure has the advantages of simple construction and controllable stroke.

[0045] In another embodiment, Figure 2 As shown, the distance between the two placement seats 103 is kept corresponding to the distance between the two punching seats 301 to meet the structural design requirements of the double-station transfer mechanism 200.

[0046] In another embodiment, Figure 2 As shown, the two placement seats 103 and the two punching seats 301 are located on the same straight line to meet the structural design requirements of the double-station transfer mechanism 200.

One of the two brackets 208 is also provided with a third screw device driven by a third servo motor 209. The third screw device is connected to the second guide rail 204 to realize displacement control of the double-station punching mechanism 300.

[0048] In another embodiment, Figure 1 and Figure 2 As shown, a baffle 306 is provided on each of the frames 1 on both sides of the double-station punching mechanism 300. The baffle 306 has a avoidance hole 307 corresponding to the second clamp 201 to prevent debris generated during the punching process from splashing outwards.

[0049] In another embodiment, Figure 1As shown, a guide groove 401 is also obliquely provided on the frame 1, and the guide groove 401 is located below the two punching seats 301. A chip box 402 is also provided at the lower end of the guide groove 401 to guide the debris generated during the punching process to the outside of the frame 1 and collect it using the chip box 402.

[0050] In another embodiment, an output crawler is further included, which is located on the side of the frame 1 away from the feeding mechanism 100.
