[0033] The direction adjustment device 2 also includes a driving member 3 arranged in the housing 12, and the driving member 3 includes a limiting sleeve 31 fixedly connected to the inner wall of the housing 12, and a driving bevel gear 32 is relatively rotatably arranged on the limiting sleeve 31. Rotating bevel gears 33 are rotatably arranged on both sides of the limiting sleeve 31 on the inner wall of the housing 12, and the two rotating bevel gears 33 are meshed with the driving bevel gear 32. The two rotating bevel gears 33 are respectively located at two card cavities 22 on the rotating card sleeve 21, and the end faces of the rotating bevel gears 33 are provided with card teeth 34 meshing with the ratchet 24 in the card cavity 22. The main shaft of the reducer 11 is axially connected to one of the rotating bevel gears 33, and the swing head device 4 is transmission-coordinated with the rotating card rod 25;
[0034] When the workpiece is processed by the cutter head device 7, one of the rotating bevel gears 33 is rotated under the drive of the reducer 11. When one of the rotating bevel gears 33 rotates, it can drive the two driving bevel gears 32 on the limit sleeve 31 to rotate, and the two driving bevel gears 32 can drive the other rotating bevel gear 33 to rotate. At this time, the two rotating bevel gears 33 rotate clockwise and counterclockwise respectively.

When the two rotating bevel gears 33 rotate, one rotating bevel gear 33 can drive the meshed ratchet 24 to make the rotating clamping sleeve 21 rotate clockwise, and the ratchet 24 on the rotating clamping sleeve 21 abuts against the clamping ball 26 on the rotating clamping rod 25, thereby synchronously driving the rotating clamping rod 25 to rotate clockwise, so that the rotating clamping rod 25 can drive the subsequent swing head device 4 to rotate and swing;
[0045] When the swing head device 4 needs to adjust the swing direction, the adjusting frame 213 is driven to extend in the dovetail groove 212 by pushing the electric cylinder 211, and the adjusting frame 213 will drive the ring sleeve 29 to slide on the rotating clamping sleeve 21. At this time, the clamping rod 210 on the ring sleeve 29 contacts the inclined groove 27 on the rotating clamping rod 25, and the rotating clamping rod 25 rotates in the rotating clamping sleeve 21. When the rotating clamping rod 25 deflects, the two clamping balls 26 set on the rotating clamping rod 25 will contact the two pawls 24 respectively, so that the two pawls 24 deflect on the vertical rod 23, and the pawl 24 meshing with the rotating bevel gear 33 rotating clockwise will separate the pawl 24 from the rotating bevel gear 33 under the abutment of the clamping ball 26, and the other pawl 24 will mesh with the clamping teeth 34 on the other rotating bevel gear 33. At this time, the two pawls 24 are realized. The switching of the meshing with the two rotating bevel gears 33, since the two rotating bevel gears 33 have different rotation directions, when the other rotating bevel gear 33 rotates, the other rotating bevel gear 33 rotates counterclockwise, which will drive the corresponding meshing ratchet 24 to make the rotating sleeve 21 rotate counterclockwise, and the rotating sleeve 21 rotates counterclockwise to drive the rotating clamping rod 25 to rotate counterclockwise, thereby realizing the switching of the two rotation directions of the reducer 11. Through this setting, when the swing head device 4 controls the tool head device 7 to process the workpiece, the swing head device 4 can be flexibly swung in different directions under the switching of the rotation direction of the reducer 11. The device only uses one reducer 11 to adjust the direction of the swing head device 4, which can improve the stability of the equipment, reduce the energy consumption of workpiece processing, and is more convenient to use.
[0046] When adjusting the rotation angle of the cutter head device 7A in the axial direction, the clamping rod 54 in the accommodating cavity 53 is driven by the pressure spring 55 to make the upper end of the clamping rod 54 dock with the clamping slot 52 on the rotating clamping rod 25. At this time, the rotation of the rotating clamping rod 25 will drive the clamping rod 54 clamped in the clamping slot 52 to drive the carrier 51 to rotate around the center of the rotating clamping rod 25. When the carrier 51 rotates, it can synchronously drive the swing frame 610 to rotate with the center of the rotating clamping rod 25, thereby realizing the rotation and swing of the cutter head device 7A in the axial direction.
[0047] When the cutter head device 7 is swung on the B axis, the switching frame 613 needs to slide on the two fixed rods 612. When the switching frame 613 slides, the two wedge frames 615 on the switching frame 613 will contact the bottom of the clamping rod 54 and the wedge clamping plate 64. At this time, the clamping rod 54 moves downward under the drive of the pressure spring 55, and the upper end of the clamping rod 54 will separate from the clamping groove 52 on the rotating clamping rod 25, so that the carrier 51 stays in the swing position of the A axis, and the other wedge frame 615 in contact with the wedge clamping plate 64 will drive the wedge clamping plate 64 to move toward the direction of the positioning clamping shaft 63. The side wall of the wedge clamping plate 64 squeezes the conically arranged positioning clamping shaft 63, so that the outer wall of the positioning clamping shaft 63 is tightly attached to the inner wall of the rotating sleeve shaft 61. At this time, when the rotating clamping rod 25 rotates, the rotating clamping rod 25 drives the positioning clamping shaft 63 to rotate, which will cause the rotating sleeve shaft 6 1 rotates, the rotation of the rotating sleeve shaft 61 will cause the rotating bevel gear 62 to rotate, and the rotating bevel gear 62 drives one of the transmission bevel gears 67 to rotate so that the other transmission bevel gear 67 rotates, and the other transmission bevel gear 67 drives the adjusting bevel gear 69 to rotate. When the adjusting bevel gear 69 rotates, the adjusting bevel gear 69 drives the swing rod 68 to rotate, so that the swing frame 610 can rotate around the center of the swing rod 68, thereby realizing the swing of the cutter head device 7 in the B-axis direction. Through this setting, the cutter head device 7 can be swung in the A-axis direction and the B-axis direction, so that the cutter head device 7 can quickly change direction during use, and when the rotating clamping rod 25 is driven by the direction adjustment device 2 to rotate in different directions, it can drive the carrier frame 51 and the swing frame 610 to swing in different directions, so that the cutter head device 7 can rotate and swing in any direction;
[0048] When the rotating motor 71 drives the driving rod 72 to rotate, the rotation of the driving rod 72 will drive the limiting cylinder 73 and the moving cylinder 77 which are clamped on the driving rod 72 to rotate synchronously. When the rotating motor 71 adjusts the speed, the driving rod 72 rotates rapidly. Under the action of centrifugal force, the centrifugal frame 79 hinged on the outer wall of the driving moving cylinder 77 will be expanded. When the centrifugal frame 79 on the outer wall of the moving cylinder 77 is expanded outward, the moving cylinder 77 will move on the driving rod 72. The movement of the moving cylinder 77 drives the connecting frame 710 to deflect the limiting frame 76. When the connecting frame 710 set at the other end of the limiting frame 76 contacts the limiting groove 75 on the limiting cylinder 73, the limiting cylinder 73 will be The movable rod 72 moves, and the outer wall of the limiting cylinder 73 is conically set and abuts against the contact rod 611, so that the contact rod 611 can slide on the adjusting bevel gear 69, and the end of the contact rod 611 away from the adjusting bevel gear 69 contacts the switching frame 613, so that the switching frame 613 moves so that the two wedge frames 615 contact the clamping rod 54 and the wedge clamping plate 64 respectively, thereby realizing the switching of the tool head device 7 in the A-axis and B-axis directions. The rotation speed of the driving rod 72 is adjusted by this setting, and the contact rod 611 is moved under the action of the rotational speed centrifugal force, and then the rotation and swinging switching of the tool head device 7 is realized in cooperation with the swing head device 4, thereby improving the effect of switching different angles of the workpiece during machining.
