Abstract
Description
Technical Field
[0001] This invention relates to the field of hot forging technology, and in particular to a multi-angle flipping gripper for forging workpieces. Background Technology
[0002] The hot die forging industry is characterized by high noise and dust levels, poor working conditions, and high labor intensity, leading to difficulties and high costs in recruiting personnel, and thus increasing the demand for automation. With product iteration and innovation, it has been found that for workpieces requiring rotation during handling, rotary cylinders cannot achieve ideal results and suffer from poor precision due to production line layout and equipment space limitations. Therefore, a multi-angle rotating gear and rack gripper designed for forging workpieces requiring rotation angles during product handling is essential. Summary of the Invention
[0003] In view of this, the purpose of this invention is to provide a multi-angle flipping clamping gripper for forging workpieces, which solves the problems in the background art.
[0004] To achieve the above objectives, the present invention provides a multi-angle flipping gripper for forging workpieces, comprising a mounting rod, a connecting flange at one end of the mounting rod, and a cylinder at the other end of the mounting rod. The end of the cylinder away from the connecting flange is an output end, which is connected to an adapter. A floating connector is connected to the adapter. A rack is connected to the side of the floating connector away from the adapter, and the rack is meshed with a gear. A transmission box is located at the end of the mounting rod away from the connecting flange. A shaft is connected to the gear and rotatably connected within the transmission box. A gripping mechanism is connected to the end of the shaft away from the gear through the transmission box. The rack is limited to its maximum stroke by a limiting mechanism. The floating connector adjusts the cylinder stroke by an adjusting mechanism.
[0005] Preferably, the clamping mechanism includes a mounting base disposed at the end of the shaft away from the gear, a cylinder seat disposed on one side of the mounting base, two finger cylinders disposed inside the cylinder seat, a clamping arm connected to the output end of the finger cylinders, and fingers disposed on the clamping arm.
[0006] Preferably, the limiting mechanism includes a slide rail disposed on the back side of the rack, a slider sliding on the surface of the slide rail, one side of the slider being fixed to the surface of the transmission box via a connecting arm; limiting blocks are provided at both ends of the rack to restrict the movement of the slider.
[0007] Preferably, the adjustment mechanism includes two threaded blocks disposed on the surface of the mounting rod, a floating joint located between the two threaded blocks, and an adjusting screw threadedly connected to the threaded hole of the threaded block. The floating joint contacts the adjusting screw to achieve limit adjustment of the cylinder stroke.
[0008] Preferably, a heat insulation pad is provided between the clamping arm and the cylinder seat.
[0009] Preferably, the finger has a U-shaped groove.
[0010] Preferably, the cylinder is equipped with a speed regulating valve connected to an air source for adjusting the pushing and pulling speed.
[0011] Preferably, the finger cylinder is equipped with a speed regulating valve connected to an air source for adjusting the pushing and pulling speed.
[0012] The beneficial effects of this invention are as follows: This invention achieves movement operation by connecting a flange to a robot arm. A cylinder drives an adapter to move, thereby moving the floating joint, which in turn causes the rack to shift laterally, rotating the gear and causing the clamping mechanism to flip. The clamping mechanism holds the workpiece, thus achieving high-torque rotation with reliable precision. The rack is limited by a limiting mechanism to control the maximum stroke angle of the gear rotation. The floating joint adjusts the cylinder stroke through an adjustment mechanism to control the gear rotation stroke.
[0013] The limiting mechanism achieves the limiting of the direction of movement by sliding the slide rail on the back of the rack and the slider fixed to the surface of the transmission box by the connecting arm, thereby achieving stable control of the rotation angle of the gear; the rack limits the movement position of the slider by the limiting blocks set at both ends, thereby limiting the maximum angle of gear rotation.
[0014] The adjustment mechanism uses two screws threaded into the threaded hole of the threaded block to limit the position of both ends of the floating joint. The position of the adjusting screws on the threaded block can be adjusted through the thread, thereby realizing the adjustment of the gear stroke.
[0015] The clamping mechanism achieves rotation by connecting the mounting base to the gear shaft. The mounting base is connected to the cylinder seat to set the finger cylinder. Activating the finger cylinder drives the clamping arm to move, thereby moving the finger to achieve clamping. The clamping arm and the cylinder seat are equipped with heat insulation pads to isolate a certain amount of heat. The finger is equipped with a U-shaped groove for strong compatibility.
[0016] Both the cylinder and the finger cylinder are equipped with speed control valves connected to the air source to adjust the pushing and pulling speed, thereby adjusting the flipping and clamping speed. Attached Figure Description

[0022] like Figures 1 to 3As shown, a multi-angle flipping gripper for forging workpieces includes a mounting rod 1, with a connecting flange 2 at one end of the mounting rod 1. The connecting flange 2 is connected to a robot arm. A cylinder 3 is mounted on the surface of the mounting rod 1. The end of the cylinder 3 away from the connecting flange 2 is the output end, which is connected to an adapter 4. A floating connector 5 is connected to the adapter 4. A rack 6 is connected to the side of the floating connector 5 away from the adapter 4. The rack 6 is meshed with a gear 7. A transmission box 8 is located at the end of the mounting rod 1 away from the connecting flange 2. A shaft is connected to the gear 7 and is rotatably connected inside the transmission box 8. A gripping mechanism is connected to the end of the shaft away from the gear 7 through the transmission box 8. The rack 6 is limited to its maximum stroke by a limiting mechanism. The floating connector 5 adjusts the cylinder stroke by an adjusting mechanism. The movement is achieved by connecting flange 2 to the robot arm. The movement of the floating joint 5 is achieved by moving the adapter 4 through cylinder 3, thereby realizing the lateral displacement of rack 6, driving gear 7 to rotate, and realizing the flipping of the clamping mechanism. The clamping mechanism holds the workpiece, thus achieving high torque rotation with reliable precision. The rack 6 achieves maximum stroke limit through the limit mechanism to control the maximum angle of rotation of gear 7. The floating joint 5 controls the rotation stroke of gear 7 by adjusting the cylinder stroke through the adjustment mechanism.
[0023] The clamping mechanism includes a mounting base 9 located at the end of the shaft away from the gear 7. A cylinder seat 10 is located on one side of the mounting base 9, and two finger cylinders 11 are housed within the cylinder seat 10. A clamping arm 12 is connected to the output end of each finger cylinder 11, and a finger 13 is mounted on the clamping arm 12. Each finger 13 has a U-shaped groove. A heat insulation pad 20 is placed between the clamping arm 12 and the cylinder seat 10. The clamping mechanism is flipped by connecting the mounting base 9 to the shaft of the gear 7. The mounting base 9 connects to the cylinder seat 10 to hold the finger cylinders 11. Activating the finger cylinders 11 moves the clamping arm 12, thereby moving the finger 13 and achieving clamping. The heat insulation pad 20 between the clamping arm 12 and the cylinder seat 10 isolates some heat. The U-shaped groove on the finger 13 provides strong compatibility.
[0024] The limiting mechanism includes a slide rail 14 disposed on the back side of the rack 6, and a slider 15 sliding on the surface of the slide rail 14. One side of the slider 15 is fixed to the surface of the transmission box 8 via a connecting arm 16. Limiting blocks 17 are provided at both ends of the rack 6 to restrict the movement of the slider 15. The limiting mechanism achieves the limiting of the direction of movement by means of the sliding cooperation between the slide rail 14 on the back side of the rack 6 and the slider 15 fixed to the surface of the transmission box 8 via the connecting arm 8, thereby achieving stable control of the rotation angle of the gear 7. The limiting blocks 17 at both ends of the rack 6 limit the movement position of the slider 15, thereby limiting the maximum angle of rotation of the gear 7.
[0025] The adjustment mechanism includes two threaded blocks 18 disposed on the surface of the mounting rod 1, with a floating joint 5 located between the two threaded blocks 18. An adjusting screw 19 is threadedly connected to the threaded hole of each threaded block 18. The floating joint 5 contacts the adjusting screw 19 to limit the cylinder stroke. The adjustment mechanism limits the positions of both ends of the floating joint 5 through the two screws 19 threaded into the threaded holes of the threaded blocks 18. The adjusting screw 19 can be adjusted in position on the threaded blocks 18 via the thread, thereby adjusting the gear stroke.
[0026] The cylinder 3 is equipped with a speed-regulating valve connected to an air source for adjusting the pushing and pulling speed. The finger cylinder 11 is also equipped with a speed-regulating valve connected to an air source for adjusting the pushing and pulling speed.
