Technical Field

[0001] The utility model relates to the technical field of bogie clamping, in particular to a clamping machine for numerical control machining of bogies. Background Art

[0002] The bogie is one of the most important components in the rail vehicle structure. The main structure of the bogie is composed of a crossbeam and two side beams, among which the side beam is a hollow structure composed of an upper plate, a lower plate, a vertical plate and an end plate that cooperate with each other.

[0003] Since the side wall shape of the bogie side beam is arc-shaped, the bogie side beam has concave and convex parts. When the clamping plate is used to clamp the side wall of the bogie side beam, it is mostly in contact with the convex part of the bogie side beam and cannot fit with the side wall of the bogie side beam, resulting in unstable clamping of the bogie. In order to adapt to the clamping of the concave and convex parts of the side wall of the bogie side beam, a clamping machine for CNC machining of the bogie is proposed. Utility Model Content

DETAILED DESCRIPTION

[0020] 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.

[0022] See also Figure 1-5 The housing 1 and the movable seat 2 are provided with an adaptive clamping assembly 4 for adaptively clamping the bogie. The adaptive clamping assembly 4 includes a servo motor 41, a bidirectional threaded rod 42, a connecting seat 43, a driven seat 44 and a clamping seat 45. The servo motor 41 is fixedly mounted on the side wall of the housing 1, the bidirectional threaded rod 42 is fixedly mounted on the output shaft of the servo motor 41, the connecting seat 43 is threadedly connected to the outer surface of the bidirectional threaded rod 42, and the connecting seats 43 on both sides are threadedly connected to the positive and negative threads on the outer surface of the bidirectional threaded rod 42. When the bidirectional threaded rod 42 rotates forward and backward, the two sides are driven The connecting seats 43 move closer to or away from each other, and the inner wall of the fixing hole 3 is slidably connected to the connecting seat 43, which limits the freedom of the connecting seat 43 in the rotation direction, so that the connecting seat 43 can only move but not rotate. After the servo motor 41 is started, the bidirectional threaded rod 42 rotates, driving the connecting seats 43 on both sides to move relative to each other, gradually performing adaptive clamping work on the bogie. The connecting seat 43 is fixedly connected to the movable seat 2, and the side wall of the connecting seat 43 is fixedly connected to a connecting rod 5 fixedly connected to the movable seat 2. The connecting rod 5 is arc-shaped and can drive the movable seat 2 to move together.

[0023] Moreover, the driven seat 44 is longitudinally slidably connected inside the movable seat 2. The driven seat 44 can slide back and forth inside the movable seat 2. The shape of the driven seat 44 is an isosceles trapezoid. The clamping seat 45 is transversely slidably connected inside the movable seat 2. The clamping seat 45 can slide left and right inside the movable seat 2. The end of the driven seat 44 is in contact with the end of the clamping seat 45. The driven seat 44 can push the clamping seat 45 to move back and forth, and then push the driven seat 44 on the other side to move back and forth accordingly, so as to adapt to the concave and convex parts of the outer contour of the bogie side beam, thereby stably clamping the bogie. The contact surface between the clamping seat 45 and the driven seat 44 is an inclined surface, enabling the driven seat 44 and the clamping seat 45 to push each other and fit with the concave and convex parts of the bogie side beam. The side of the clamping seat 45 away from the driven seat 44 is an arc surface.

[0024] Meanwhile, a protrusion 6 is fixedly connected to the side wall of the driven seat 44. A groove 7 is formed on the side of the clamping seat 45 close to the driven seat 44. The protrusion 6 is slidably connected with the groove 7. The shapes of the protrusion 6 and the groove 7 are both dovetail-shaped. With the connection between the protrusion 6 and the groove 7, the separation between the driven seat 44 and the clamping seat 45 is avoided. A limiting groove 8 corresponding to the driven seat 44 and the clamping seat 45 is formed inside the movable seat 2. The shape of the limiting groove 8 is a U-shaped, enabling the driven seat 44 to only move back and forth, and the clamping seat 45 to only move left and right. An extension groove 9 communicating with the limiting groove 8 is formed inside the movable seat 2, providing a moving space for the driven seat 44 and the clamping seat 45. The shape of the extension groove 9 is square.

[0025] Please refer to Figure 2 , a shielding assembly 10 for protecting the bidirectional threaded rod 42 is provided on the housing 1 and the connecting seat 43. The shielding assembly 10 includes a fixed plate 101, a movable plate 102 and an extension plate 103. The fixed plate 101 is fixedly installed on the inner top wall of the housing 1. The movable plate 102 is fixedly installed on the opposite sides of the two connecting seats 43 and can move along with the connecting seat 43. The lower surface of the fixed plate 101 is slidably connected with the upper surface of the movable plate 102, capable of pushing off the debris on the upper surface of the movable plate 102. The side shape of the movable plate 102 is an inverted V shape, reducing the retention of debris on the movable plate 102.

[0026] In addition, the extension plate 103 is fixedly installed on the outside of the connecting seat 43. The fixed plate 101, the movable plate 102 and the extension plate 103 can shield the bidirectional threaded rod 42, preventing debris from falling on the outer surface of the bidirectional threaded rod 42 and affecting the transmission work of the bidirectional threaded rod 42. An opening 11 slidably connected with the extension plate 103 is formed on the side wall of the housing 1. The housing 1 can push off the debris on the outer surface of the extension plate 103. The fixed plate 101, the movable plate 102 and the extension plate 103 are all located directly above the bidirectional threaded rod 42.

[0027] When this embodiment is in use, the bogie is placed on the upper surface of the casing 1, the servo motor 41 is started, the bidirectional threaded rod 42 rotates, and the connecting seats 43 on both sides move relatively along the inner wall of the fixing hole 3, and the driven seat 44 and the clamping seat 45 on the movable seat 2 move toward the side wall of the bogie side beam, and the clamping seat 45 first contacts the convex part of the bogie side beam. As the connecting seat 43 continues to move, the clamping seat 45 that first contacts the bogie side beam pushes the driven seat 44, and the driven seat 44 pushes the clamping seat 45 on the other side, so that the clamping seat 45 on the other side also moves toward the bogie side beam and gradually contacts the concave part of the bogie side beam. When it contacts and abuts with the concave and convex parts of the bogie side beam, the clamping work of the bogie is completed.

[0028] The beneficial effects of the above embodiments are:

[0029] The clamping machine for CNC machining of the bogie is provided with an adaptive clamping component 4. After use, the adaptive clamping component 4 drives the connecting seats 43 on both sides to move under the rotation of the bidirectional threaded rod 42, so that the driven seat 44 and the clamping seat 45 in the movable seat 2 move accordingly. When the clamping seat 45 contacts the convex part of the bogie side beam, it will push the driven seat 44, so that the driven seat 44 pushes the clamping seat 45 on the other side to move toward the concave part of the bogie side beam, so that the clamping seat 45 is respectively in contact with the concave and convex parts of the bogie side beam, thereby improving the fit of the bogie clamping and ensuring the stability of the bogie clamping. The clamping seat 45 is moved and adjusted according to the concave and convex parts of the bogie side beam, so as to realize adaptive clamping of the bogie.
