DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.

[0020] As Figures 1 to 5 Indicated, the utility model provides a kind of automatic punching equipment for automobile shock absorber production and processing, including frame 1, the top vertical fixed connection of frame 1 has cylinder 2, the output end of cylinder 2 is fixedly connected with connecting frame 3, connecting frame 3 is horizontally provided with rotating shaft 4, rotating shaft 4 is rotationally matched with connecting frame 3, one-way bearing 5 is installed on the outer wall of one-way bearing 5, and ring gear 6 is installed on the outer wall of one-way bearing 5, rack 7 is vertically fixedly connected on the top of frame 1, rack 7 is matched with ring gear 6, fixed seat 8 is rotationally matched in connecting frame 3, fixed seat 8 is fixedly installed on rotating shaft 4, and multiple punch 9 are fixedly connected on the outer wall of fixed seat 8 at equal intervals to punch workpiece.

[0021] When punching workpiece, cylinder 2 drives connecting frame 3 to vertically move down, and punch 9 also moves down synchronously with connecting frame 3, so that punch 9 punches the workpiece below.

[0022] During the movement of connecting frame 3, ring gear 6 also moves down, since rack 7 is engaged with ring gear 6, rack 7 drives ring gear 6 to rotate, since one-way bearing 5 exists, ring gear 6 only idles in this process, and rotating shaft 4 is not rotated.

[0023] After punch 9 finishes punching, cylinder 2 drives connecting frame 3 to move up, and punch 9 also moves up and resets, and the upward movement of connecting frame 3 makes ring gear 6 move up, and rack 7 drives ring gear 6 to rotate reversely during the upward movement of ring gear 6, at this time, reversely rotating ring gear 6 drives rotating shaft 4 to rotate through one-way bearing 5.

[0024] The rotation of the rotating shaft 4 drives the fixed seat 8 to rotate synchronously, and the punch 9 on the fixed seat 8 also revolves around the rotating shaft 4, so that the punch 9 for punching work is switched.

[0025] Compared with the prior art, the automatic punching equipment for automobile shock absorber production and processing provided by the utility model can switch the punch 9 for punching work through the rotation of the fixed seat 8, so as to reduce the wear rate of the single punch 9 and ensure the quality of workpiece punching.

[0026] As shown in Figure 6 and Figure 7 , the rotating shaft 4 is provided with a limiting structure for preventing the rotating shaft 4 from rotating at will, the limiting structure comprises a rotating disc 10, a plurality of arc-shaped limiting grooves 11 are formed at equal intervals on the outer wall of the rotating disc 10, a sliding rod 14 is vertically and fixedly connected to the inner wall of the connecting frame 3, a sliding pipe 13 is slidably connected to the bottom of the sliding rod 14, a round head marble 12 is fixedly connected to the bottom end of the sliding pipe 13, the round head marble 12 is slidably connected with the limiting groove 11, and the sliding rod 14 is provided with a spring 15 for applying an elastic force to the sliding pipe 13.

[0027] Under the elastic force of the spring 15, the round head marble 12 at the bottom of the sliding pipe 13 can enter the limiting groove 11, and the round head marble 12 and the limiting groove 11 cooperate to limit the rotating shaft 4 to a certain extent, thereby preventing the rotating shaft 4 from rotating during the idling process of the ring gear 6.

[0028] As shown in Figures 2-4 , the bottom of the rack 1 is fixedly connected with a motor frame 23, the middle of the motor frame 23 is fixedly connected with a stepping motor 22, and the output end of the stepping motor 22 is fixedly connected with a workbench 16.

[0029] During the punching work, the workbench 16 is used to carry the workpiece, and after completing a punching work, the workbench 16 is driven to rotate by the stepping motor 22, so as to complete the feeding and discharging of the workpiece.

[0030] As shown in Figure 2 and Figure 3 , a plurality of clamps are arranged at equal intervals on the upper surface of the workbench 16 to clamp the workpiece, the number of clamps is equal to the number of punches 9, the clamp comprises a supporting block 17, the supporting block 17 is fixedly connected to the upper surface of the workbench 16, and the bottom of the supporting block 17 penetrates through the workbench 16, a sliding groove 20 is formed on the upper surface of the supporting block 17, a sliding block 18 is slidably connected in the sliding groove 20, a tension spring 19 is arranged in the sliding groove 20 to apply a tension force to the sliding block 18, and a clamping block 21 is fixedly connected to the upper surface of the sliding block 18.

[0031] Under the elastic force of the tension spring 19, the sliding blocks 18 on the two sides of the supporting block 17 have a tendency to approach each other, so that the distance between the clamping blocks 21 on the two sliding blocks 18 is reduced, the workpiece is placed between the two sliding blocks 18, and the clamping blocks 21 clamp and fix the workpiece.

[0032] The working principle and use process of the utility model are as follows:

[0033] When the workpiece is punched, the cylinder 2 drives the connecting frame 3 to move vertically downward, and the punch 9 also moves downward synchronously with the connecting frame 3, so that the punch 9 punches the workpiece below.

[0034] During the downward movement of the connecting frame 3, the ring gear 6 also moves downward, and since the rack 7 is engaged with the ring gear 6, the rack 7 drives the ring gear 6 to rotate, and since the one-way bearing 5 exists, the ring gear 6 only idles during this process and does not drive the rotating shaft 4 to rotate.

[0035] After the punch 9 finishes punching, the cylinder 2 drives the connecting frame 3 to move upward, and the punch 9 also moves upward and resets, and the upward movement of the connecting frame 3 causes the ring gear 6 to move upward, and during the upward movement of the ring gear 6, the rack 7 drives the ring gear 6 to rotate in the opposite direction, at this time, the ring gear 6 rotating in the opposite direction drives the rotating shaft 4 to rotate through the one-way bearing 5.

[0036] The rotation of the rotating shaft 4 drives the fixed seat 8 to rotate synchronously, and the punch 9 on the fixed seat 8 also revolves around the rotating shaft 4, thereby switching the punch 9 that is punching.

[0037] Compared with the prior art, the automatic punching equipment for automobile shock absorber production and processing provided by the utility model switches the punch 9 that is punching through the rotation of the fixed seat 8 to reduce the wear rate of a single punch 9 and ensure the quality of workpiece punching.

[0038] The sliding pipe 13 allows the round head marble 12 at the bottom of the sliding pipe 13 to enter the limiting groove 11 under the elastic force of the spring 15, and the round head marble 12 cooperates with the limiting groove 11 to limit the rotating shaft 4 to a certain extent, thereby preventing the rotating shaft 4 from rotating during the idling of the ring gear 6.

[0039] During the punching work, the workbench 16 is used to carry the workpiece, and after completing a punching work, the workbench 16 is driven to rotate by the stepping motor 22, thereby completing the feeding and discharging of the workpiece.

[0040] Under the elastic force of the tension spring 19, the sliding blocks 18 on both sides of the supporting block 17 have a tendency to approach each other, thereby reducing the spacing of the clamping blocks 21 on the two sliding blocks 18, and the workpiece is placed between the two sliding blocks 18, and the clamping blocks 21 clamp and fix the workpiece.
