[0027] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention. Example 1

[0028] In order to solve the technical problems in the background technology, an automatic clamping and flipping device for a powder metallurgy press is provided as follows:

[0029] Combine Figure 1-Figure 4As shown, the utility model provides an automatic clamping and flipping device for a powder metallurgy press, comprising a vertical mounting plate 1, a slider 11 being mounted on one side of the mounting plate 1 in a vertical sliding manner, a driving mechanism 12 acting on the slider 11 being mounted on the mounting plate 1, for making the slider 11 slide or stop sliding on the mounting plate 1; a mounting frame 2 is mounted on the slider 11, a horizontal telescopic rod 21 being symmetrically fixed on one side of the mounting frame 2 away from the mounting plate 1, a mounting shell 22 being fixedly mounted on the telescopic ends of the two telescopic rods 21, an electric push rod 23 connected to the mounting shell 22 being fixedly mounted on the mounting frame 2, A horizontal rotating shaft 221 is rotatably mounted on the mounting shell 22, and a clamping mechanism 3 for clamping the gear is mounted on one end of the rotating shaft 221. A motor 222 for driving the rotating shaft 221 to rotate is fixedly mounted on the mounting shell 22; two vertical telescopic rods 24 are symmetrically fixed on the top of the mounting shell 22, and a fixing plate 4 is mounted on the top of the two telescopic rods 24. An electric push rod 25 connected to the fixing plate 4 is fixedly mounted on the top of the mounting shell 22, and a positioning mechanism 5 for positioning the gear is mounted on the fixing plate 4 and directly above the clamping mechanism 3. This device is powered by an external power supply.

[0030] When the gear is in use, the slider 11 is displaced on the mounting plate 1 by the driving mechanism 12, and the mounting shell 22 is displaced away from the mounting frame 2 by the cooperation of the electric push rod 12, so that the clamping mechanism 3 is close to the gear. At this time, the gear can be clamped and fixed by the clamping mechanism 3. When the gear is flipped, the slider 11 is displaced on the mounting plate 1 by the driving mechanism 12, and the motor 122 is controlled to rotate the rotating shaft 221 180 degrees on the mounting shell 22, so that the gear can be flipped. When the gear is transferred and unloaded, the gear can be clamped and fixed by the clamping mechanism 3, so that the positioning mechanism 5 is located just above the gear. At this time, the gear can be positioned by the positioning mechanism 5, thereby improving the fixing effect of the gear, replacing the point contact method between the two splints and the gear, and effectively preventing the gear from falling from between the two splints when the gear is transferred and unloaded, thereby improving stability. Example 2

[0031] like Figure 1-Figure 4 As shown, based on the above embodiment, this embodiment further provides the following content:

[0032] In this embodiment, the driving mechanism 12 includes a threaded column 121 that is vertically and rotatably mounted on the mounting plate 1. The threaded column 121 is threadedly connected to the slider 11. A second motor 122 is fixedly mounted on the mounting plate 1 for driving the threaded column 121 to rotate. When in use, the second motor 122 is controlled to be turned on. When the second motor 122 works, the threaded column 121 can be rotated on the mounting plate 1, thereby causing the slider 11 to slide on the mounting plate 1, which is convenient for control.

[0033] The two clamping plates 33 are respectively located on both sides of the gear, and the motor 35 is controlled to work to make the two-way threaded rod 34 rotate on the mounting block 31, so that the two sliding blocks 32 slide close to each other on the mounting block 31, and the gear can be clamped and fixed by the two clamping plates 33.

[0034] In this embodiment, the positioning mechanism 5 includes a transverse plate 51 fixedly mounted on the end of the fixed plate 4 and located directly above the two clamping plates 33. A sliding groove 511 is provided on the transverse plate 51 and located directly above the opposite sides of the two clamping plates 33. Two positioning plates 52 are slidably mounted on the transverse plate 51 and located in the sliding groove 511. A moving block 53 is hinged on the top of the fixed plate 4 and slides along the direction of the transverse plate 51. Two hinged rods 54 are hinged on the moving block 53. The other ends of the two hinged rods 54 are respectively hinged to the two positioning plates 52. An electric push rod 3 55 connected to the moving block 53 is fixedly mounted on the top of the fixed plate 4. Before the gear is clamped and flipped, the mounting shell 22 is displaced along the telescopic rod 1 21 away from the mounting frame 2 through the electric push rod 1 23, so that the mounting block 31 is close to the mounting frame 2 When approaching the gear, the fixed plate 4 is displaced downward along the telescopic rod 24 by the electric push rod 25, so that the two positioning plates 52 are inserted into the center hole of the gear, and the moving block 53 is displaced toward the horizontal plate 51 by the electric push rod 3 55. The two hinged rods 54 rotate around their own hinge points on the moving block 53, and the two hinged rods 54 rotate between the two positioning plates 52 respectively, so that the two positioning plates 52 slide away from each other in the slide groove 511, so that the two positioning plates 52 can form a conflict with the inner side wall of the center hole of the gear, and the gear can be positioned by the positioning mechanism 5, and then the fixed plate 4 is displaced upward along the telescopic rod 24 by the electric push rod 25, so that the gear can be located on the opposite side of the two clamping plates 33. At this time, the gear can be clamped and fixed by the clamping mechanism 3. Example 3

[0035] like Figure 1-Figure 4 As shown, based on the above embodiment, this embodiment further provides the following content:

[0036] In this embodiment, the positioning plate 52 includes a connecting plate 521 slidably mounted in the slide groove 511, and a fan-shaped block 522 is fixedly mounted on the bottom of the connecting plate 521. When the two connecting plates 521 are fitted together, the cross-section of the two fan-shaped blocks 522 forms a circle. The two hinged rods 54 are hinged to the two connecting plates 521 respectively. By setting the connecting plate 521 and the fan-shaped blocks 522, when the gear is transferred, the gear is clamped and fixed by the clamping mechanism 3, and the moving block 53 is moved away from the horizontal plate 51 by the electric push rod 3 55. The displacement can cancel the conflict between the positioning plate 52 and the center hole of the gear. At this time, the fixed plate 4 is displaced downward along the telescopic rod 24 by the electric push rod 25, so that the top of the sector block 522 and the bottom of the gear are located on the same horizontal plane, and then the moving block 53 is displaced toward the horizontal plate 51 by the electric push rod 3 55, so that the two connecting plates 521 can both form a conflict with the inner side wall of the center hole of the gear. At this time, the gear is positioned by the positioning mechanism 5 and the bottom of the gear is supported by the two sector blocks 522, thereby further improving the positioning effect.

[0037] In this embodiment, a V-shaped groove is provided on one side of the two clamping plates 33 close to each other, and a rubber pad 6 is fixedly installed on the one side of the two clamping plates 33 close to each other. The special design of the V-shaped groove is provided on one side of the two clamping plates 33 close to each other facilitates the clamping and fixing of gears of different sizes by the device, thereby improving applicability. By providing the rubber pad 6, when the two clamping plates 33 clamp and fix the gear, the two rubber pads 6 form a conflict with the gear, thereby increasing the friction between the clamping plate 33 and the gear, and increasing the clamping and fixing effect of the gear.

[0038] In this embodiment, the mounting frame 2 is mounted on the slider 11 in a horizontal direction through the rotating shaft 111, and the slider 11 is fixedly mounted with a motor 4 112 for driving the rotating shaft 111 to rotate. By setting the rotating shaft 111 and the motor 4 112, when the gear is transferred and unloaded, the mounting shell 22 is moved along the telescopic rod 1 21 toward the mounting frame 2 through the electric push rod 1 23, and the two clamping plates 33 are moved to the outside of the stamping die base of the stamping machine. The motor 4 112 can be controlled to work, so that the rotating shaft 111 rotates on the slider 11, and the mounting block 31 rotates around the rotating shaft 111 toward one side of the mounting plate 1, thereby facilitating the unloading of the gear.
