[0024] like Figures 1-3As shown, a gear disc blank feeding mechanism includes a hot forging press C100. A blank conveying slide C200 is provided on the left side of the worktable of the hot forging press C100. The discharge end of the blank conveying slide is located on the left side of the worktable of the hot forging press C100. A blank turning mechanism D is provided at the discharge end of the blank conveying slide. A feeding robot C300 that can move left and right is provided above the blank turning mechanism D. A baffle is provided at the discharge end of the blank conveying slide to intercept the blank. This utility model's gear disc blank feeding mechanism realizes the mechanical feeding of blanks on a hot forging press. The blank slides down the blank conveyor slide C 200 to the discharge end, and the blank flipping mechanism D flips the blank upward to an upright state. Then, the unloading robot picks up the blank and sends it to the worktable position of the hot forging press C 100. It is convenient, practical, efficient, reduces manual intervention, and improves production safety.

[0025] In this embodiment, the loading robot C 300 includes a base plate C 310. The right end of the base plate C 310 is provided with a pair of clamping arms C 320 with the clamping ends facing right. The base plate is provided with a drive cylinder C 330 for driving the two clamping arms to open and close. The left part of the clamping arm is hinged to the base plate. The hinge part of the clamping arm is provided with an extension handle C 321. The telescopic rod of the drive cylinder and the extension handle of the two clamping arms are respectively connected by a connecting rod C 340. The drive cylinder C 330 can be a pneumatic cylinder or a hydraulic cylinder. The extension handles C 321 of the two clamping arms bend outward to form a V shape. When the telescopic rod of the drive cylinder C 330 extends, it pushes the clamping ends of the two clamping arms to clamp through the connecting rod. When the telescopic rod of the drive cylinder C 330 retracts, it pulls the clamping ends of the two clamping arms to release through the connecting rod, thus realizing the opening and closing of the two clamping arms. When the blank flipping mechanism D flips the blank upward to the upright position, the blank is just located in the middle of the clamping ends of the two clamping arms of the loading robot C.

[0026] In this embodiment, in order to achieve precise positioning, a V-shaped positioning block 322 is provided on the opposite side of the clamping ends of the two clamping arms.

[0027] In this embodiment, a horizontal linear slide 350 is provided below the loading robot 300, and the loading robot is mounted on the slide block of the horizontal linear slide. The horizontal linear slide 350 is used to control the left and right movement of the loading robot 300 to realize the loading and unloading actions.

[0028] like Figures 4-7As shown, in this embodiment, the blank flipping mechanism includes a flipping frame D1, on which a flipping clamping mechanism D2 is rotatably connected. A flipping drive assembly D3 for driving the flipping clamping mechanism to rotate is installed on the flipping frame below the flipping clamping mechanism. The flipping clamping mechanism includes a flipping base D4, on which clamping arms D5 are symmetrically and movably connected on one side. A clamping drive assembly D6 for opening and closing the two clamping arms is installed inside the flipping base. In use, the clamping drive assembly drives the clamping arms to open and close, thereby clamping the cylindrical blank falling from the conveying channel. Then... The flipping drive assembly drives the flipping clamping mechanism to flip upward, changing the flipping clamping mechanism from horizontal to vertical, and sending the cylindrical blank assembly into the upper processing equipment station to complete the flipping and movement of the blank. More specifically, the flipping seat includes horizontal seat plates D7 symmetrically arranged on the upper and lower sides. The clamping drive assembly is installed between one side of the two seat plates, and two clamping arms are symmetrically rotatably connected between the other side of the two seat plates. The two clamping arms are connected to the clamping drive assembly through a linkage mechanism D8, that is, the clamping drive assembly drives the linkage mechanism to move, thereby driving the opening and closing of the two clamping arms.

[0029] In this embodiment, to specifically realize the opening and closing of the two clamping arms, the clamping arms include a swing linkage D9. The middle part of the swing linkage is rotatably connected between the two base plates via a rotating shaft. One end of the two swing linkages is connected to the clamping drive assembly via a linkage mechanism, and the other end extends out of the flipping seat. A pawl D10 is installed on the extended end of the swing linkage. The clamping drive assembly includes a clamping telescopic push rod D11. The clamping telescopic push rod can be an existing telescopic cylinder. The non-telescopic part of the clamping telescopic push rod is fixed between the two base plates, i.e., telescopic... The cylinder liner is fixed between two seat plates, and the telescopic end faces the middle between the two clamping arms. The linkage mechanism includes a sliding block D12, which is fixed to the telescopic end of the clamping telescopic push rod and slidably connected between the two seat plates. The two ends of the sliding block are hinged to connecting rods D13, and the other end of the connecting rod is hinged to one end of the swing connecting rod on the same side. That is, the extension and retraction of the clamping telescopic push rod drives the sliding block to slide, thereby driving the two connecting rods to swing, realizing the rotation of the two swing connecting rods around the axis, and finally realizing the opening and closing of the two clamping arms.

[0030] In this embodiment, in order to achieve the flipping of the flipping seat, a rotating seat D14 is provided on the lower surface of the bottom seat plate. A rotating shaft D15, which is rotatably connected to the flipping frame, is horizontally placed inside the rotating seat. The rotating seat is located below the non-telescopic part of the clamping telescopic push rod. The flipping drive assembly includes a flipping telescopic push rod D16. The flipping telescopic push rod can be an existing telescopic cylinder. One end of the flipping telescopic push rod is hinged to the flipping frame, and the other end is hinged to the lower surface of the bottom seat plate. The end of the flipping telescopic push rod hinged to the lower surface of the seat plate is located below the middle of the two clamping arms. The extension and retraction of the flipping telescopic push rod drives the flipping seat to rotate around the axis, thereby realizing the switching of the flipping seat between horizontal and vertical states.

[0031] In this embodiment, in order to realize the sliding of the sliding block, a sliding groove D17 is provided on the upper surface of the bottom seat plate corresponding to the sliding of the sliding block. In order to limit the extreme position of the sliding block, a limiting block D18 is provided at the middle of the upper end of the sliding block, and a limiting groove D19 is provided on the top seat plate corresponding to the sliding trajectory of the limiting block.

[0032] In this embodiment, in order to extend the clamping area of ​​the two claws, the claws include an L-shaped extension arm D20. One end of the L-shaped extension arm is fixed to the extended end of the swing linkage, and a claw block D21 is installed on the other end. The arm body of the L-shaped extension arm connected to the claw block is located on the outside, that is, the two L-shaped extension arms form a U-shaped area that can be opened and closed, which facilitates the subsequent installation of the claw block.

[0033] In this embodiment, to enable the jaw block to be finely adjusted in angle on the horizontal plane as needed, the jaw block includes a locking seat D22, and a locking groove D23 is provided on the outer side of the locking seat. The end of the L-shaped extension arm is rotatably connected to the locking groove through a vertical rotating shaft. There is an adjustment gap D24 between the bottom of the locking groove and the side of the L-shaped extension arm, that is, the locking seat can swing slightly at the end of the L-shaped extension arm. On the side of the end of the L-shaped extension arm away from the bottom of the locking groove, there are symmetrical horizontal adjustment bolts D25 on both sides of the rotating shaft. The adjustment bolts pass through the L-shaped extension arm and abut against the bottom of the locking groove. That is, by adjusting the screw-in distance of the two adjustment bolts, the angle of the jaw block can be fixed, which is convenient for on-site debugging. The angle between the two jaw blocks can be adjusted as needed, which is convenient for docking with the blank.

[0034] In this embodiment, to make the clamping area of ​​the clamping block adjustable vertically, a claw portion D26 is installed on the inner side of the clamping seat. The claw portion includes a vertically arranged connecting plate D27. At least two guide holes D28 are spaced apart on the upper plate surface of the connecting plate. A guide bolt D29 is slidably connected in the guide hole. The end of the guide bolt passes through the guide hole and is screwed onto the inner side of the clamping seat. The bolt head of the guide bolt abuts against the connecting plate surface on the outer periphery of the guide hole. In use, the guide bolt is loosened, and then the connecting plate slides up and down through the guide hole. After sliding to a suitable position, the guide bolt is tightened so that the bolt head of the guide bolt clamps and fixes the connecting plate with the inner side of the clamping seat, thus achieving fixation. A horizontal V-shaped groove D30 is provided on the lower inner plate surface of the connecting plate. When the V-shaped grooves at the ends of the two L-shaped extension arms are clamped and closed, they can cooperate to fix the cylindrical blank.
