DETAILED DESCRIPTION
[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0019] Embodiment 1: Figure 1-3As shown in the figure, the present utility model provides a tool holder for gear processing. A tool holder for gear processing includes a support frame 1. A support plate 11 is fixedly connected to the bottom end of the support frame 1. A clamping device 2 is fixedly provided at the top end of the support plate 11. A rotating mechanism 4 is movably provided on one side of the top end of the support plate 11. A motor housing 3 is fixedly installed on one side of the bottom end of the support plate 11. The clamping device 2 includes two connecting rods 24. One end of each of the two connecting rods 24 is fixedly connected to a toothed plate 21. Fixed plates 23 are fixedly provided at the top ends of the two toothed plates 21. A rotating shaft 22 is rotatably provided on the outer surface of the top end of each of the two fixed plates 23. The rotating shaft 22 penetrates through the fixed plate 23 and the toothed plate 21. Claw jaws 27 are fixedly provided at the other ends of the two connecting rods 24. One end of each of the two claw jaws 27 is slidably connected to a slider 28. One end of each of the two sliders 28 is fixedly connected to the support frame 1. Fixing members 25 are fixedly connected to the middle parts of the two connecting rods 24. A first fixed shaft 251 is rotatably provided at the top end of each of the two fixing members 25. The first fixed shaft 251 penetrates through the connecting rod 24. A cylinder 26 is fixedly connected between the two fixing members 25.
[0020] By adopting the above technical solution, when the output end of the cylinder 26 pulls, the pulling force causes the fixing members 25 at both ends of the cylinder 26 to drive the two connecting rods 24 to move inward through the two first fixed shafts 251, thereby driving the two claw jaws 27 at one end of the connecting rods 24 to perform a clamping motion. The two claw jaws 27 maintain a horizontal movement through the sliding grooves 281 in the two sliders 28. The two toothed plates 21 at the other end of the connecting rods 24 rotate relative to each other through the rotating shafts 22 in the fixed plates 23, achieving the principle of automatic centering. Thus, the clamping forces of the two claw jaws 27 are consistent, ensuring that the gear does not move or deform during the clamping process. The clamping groove 271 in the claw jaw 27 is designed in a "V" shape to help the claw jaw 27 perform two-point positioning on the gear, thereby achieving the purpose of automatic centering clamping.
[0021] Clamping grooves 271 are formed at one end of each of the two claw jaws 27. The clamping groove 271 is in a "V" shape. A sliding groove 281 is formed at the end of the slider 28 connected to the claw jaw 27. The inner wall of the sliding groove 281 is slidably attached to the outer surface of one end of the claw jaw 27.
[0022] By adopting the above technical solution, the purpose is to facilitate the two-point positioning of the clamping groove 271, and the sliding groove 281 is for keeping the slider 28 moving on the same horizontal line.
[0023] Both of the two toothed plates 21 are in a fan shape, and the two toothed plates 21 are meshed with each other.
[0024] By adopting the above technical solution, it plays a role in keeping the clamping forces of the two connecting rods 24 through the cylinder 26 equal.
[0025] The support frame 1 is in a "J" shape.
[0026] The above technical solution is adopted to facilitate the two clamping claws 27 to slide through the two sliders 28 at one end of the support frame 1 .
[0027] The clamping jaws 27 are distributed in a mirror image, and the two clamping jaws 27 are on the same horizontal plane.
[0028] The purpose of adopting the above technical solution is to ensure that the fixed points of the two clamping grooves 271 are the same, thereby improving the positioning accuracy.
[0029] Embodiment 2: Figure 3 As shown, the rotating mechanism 4 includes a top plate 41, a base 42 is rotatably provided in the middle of the top plate 41, four rectangular grooves 421 are opened on the outer surface of the bottom end of the base 42, a rotating rod 43 is rotatably provided on one side of the bottom end of the base 42, a sliding pin 431 is fixedly provided on one side of the top end of the rotating rod 43, a first gear 44 is fixedly installed on the outer surface of the lower end of the rotating rod 43, a second gear 45 is meshingly connected to the outer surface of the first gear 44, a motor 47 is fixedly connected to the bottom end of the second gear 45, and the output end of the motor 47 is fixedly connected to the second gear 45, a second fixed shaft 46 is fixedly installed on the top end of the second gear 45, and the second fixed shaft 46 is fixedly connected to the central inner surface of the base 42.
[0030] By adopting the above technical solution, the output end of the motor 47 rotates the second gear 45, and the second gear 45 is fixed to the central lower end of the base 42 through the second fixed shaft 46, thereby driving the first gear 44 meshing with the second gear 45 to rotate, and the first gear 44 drives the rotating rod 43 to rotate, and the sliding pin 431 located at the top of the base 42 rotates around the rotating rod 43 as the axis point. When the sliding pin 431 passes through the rectangular groove 421 in the base 42, the eccentric force of the rotation will drive the base 42 to rotate. When the sliding pin 431 disengages from the rectangular groove 421, the force disappears and the base 42 stops rotating. When the sliding pin 431 enters the rectangular groove 421 on the other side again, it drives the base 42 to rotate again. The rotation causes the sliding pin 431 to pass through the four rectangular grooves 421 in sequence, thereby achieving the purpose of intermittent rotation.
[0031] The height of the sliding pin 431 is consistent with the depth of the rectangular groove 421 , and the outer surface of the sliding pin 431 slides in contact with the inner wall of the rectangular groove 421 .
[0032] By adopting the above technical solution, it is convenient for the sliding pin 431 to enter the rectangular groove 421 through rotation and perform eccentric movement.
[0033] The four rectangular slots 421 are distributed in a circular array.
[0034] The above technical solution is adopted to facilitate the sliding pin 431 to pass through the four rectangular slots 421 in sequence.
[0035] Working principle: The gear is placed between the two clamping jaws 27 in the clamping device 2, the cylinder 26 is started, and the output end of the cylinder 26 is pulled. The pulling force causes the fixing parts 25 at both ends of the cylinder 26 to drive the two connecting rods 24 to move inward through the two first fixed shafts 251, thereby driving the two clamping jaws 27 at one end of the connecting rod 24 to perform clamping movement. The two clamping jaws 27 maintain horizontal movement through the slide grooves 281 in the two sliders 28, and the two tooth plates 21 at the other end of the connecting rod 24 rotate with each other through the rotating shaft 22 in the fixed plate 23 to achieve the automatic centering principle, so that the clamping force of the two clamping jaws 27 is consistent, ensuring that the gear will not move or deform during the clamping process. The clamping groove 271 in the clamping jaw 27 is a "V"-shaped design, which helps the clamping jaw 27 to position the gear at two points, thereby achieving the purpose of automatic centering clamping. , start the motor 47, the output end of the motor 47 rotates the second gear 45, and the second gear 45 is fixed to the central lower end of the base 42 through the second fixed shaft 46, thereby driving the first gear 44 meshing with the second gear 45 to rotate, and the first gear 44 drives the rotating rod 43 to rotate, and the sliding pin 431 located at the top of the base 42 rotates around the rotating rod 43 as the axis point. When the sliding pin 431 passes through the rectangular groove 421 in the base 42, the eccentric force of the rotation will drive the base 42 to rotate. When the sliding pin 431 disengages from the rectangular groove 421, the force disappears, and the base 42 stops rotating. When the sliding pin 431 enters the rectangular groove 421 on the other side again, it drives the base 42 to rotate again. The rotation causes the sliding pin 431 to pass through the four rectangular grooves 421 in sequence, thereby achieving the purpose of intermittent rotation.
