Description

Technical Field

[0001] The utility model relates to the technical field of metal part processing, in particular to a device for pushing metal structural parts. Background Art

[0002] When small metal structural parts are processed on a machining center, if the manual feeding method is adopted, first, the efficiency is relatively low, which is likely to cause production delays. Second, the working intensity of manual feeding is imaginable. Third, since the metal structural parts are small in size, it is difficult to operate the manual feeding and clamping. Therefore, how to realize the automatic feeding of structural parts has become an urgent technical problem to be solved. At present, the automatic feeding has been realized through an automatic discharging and attitude correcting device, and the feeding method adopted in the process of automatic feeding is belt feeding. As an alternative, the metal structural parts are supplied by the way of pushing from the back end. For the former, the motor needs to start and stop frequently, which will affect the service life of the motor. For the latter, the problem of jammed structural parts and poor discharging is likely to occur. Therefore, how to realize the individual feeding operation of structural parts has become the key to realizing automatic feeding. Content of the Utility Model

[0003] The utility model provides a device for pushing metal structural parts to solve the above-mentioned deficiencies of the prior art, solves the problem of individual automatic pushing and feeding, and has strong practicability.

[0004] In order to achieve the purpose of the utility model, the following technology is proposed:

[0005] A device for pushing metal structural parts includes a concave part. The concave part limits the structural parts inside it. Rectangular holes are opened on both sides of the concave part. A pair of guide rails are installed on the outer wall of the concave part. A movable side plate is movably arranged on the guide rails. Multiple movable insertion plates are inserted through the movable side plate. The movable insertion plates are arranged in an equally spaced array. An inner top plate is provided at the outer end of the movable insertion plate. Multiple spring pins are inserted through the inner top plate. The inner ends of the spring pins are arranged on the movable side plate. Springs are sleeved on the inner ends of the spring pins. The springs are located between the movable side plate and the inner top plate. A top convex plate is provided on the outer wall of the inner top plate. Mounting plates are respectively installed on the upper and lower sides of the movable side plate. Side plates are installed on the mounting plates. Movable holes are opened on the side plates. A rotating arm is swingably arranged in the movable holes. The rotating arm is arranged on the side plate through a pair of hinged convex plates. The inner end of the rotating arm acts on the outer end of the top convex plate. A rocker is provided at the outer end of the rotating arm. A mounting frame is installed on the concave part. A cylinder is installed on the mounting frame. The movable end of the cylinder is installed with a movable end plate. A pair of movable arms are installed at the lower end of the movable end plate. Kidney-shaped holes are opened at the outer ends of the movable arms. The upper end of the rocker passes through the kidney-shaped hole. The cylinder can drive the movable arms to perform reciprocating motion. When the movable arms are pushed forward, it will act on the kidney-shaped hole through the rocker, so that the rotating arm rotates first, and the inner end of the rotating arm acts on the top convex plate, so that the movable insertion plates are inserted between each structural part. When the movable insertion plates move inward, then they will be driven by the cylinder to move forward. The movement of the movable insertion plates will drive each structural part to move forward, and finally realize the automatic pushing operation of the structural parts. And this pushing operation is in a one-by-one pushing mode, which can avoid the problem of material jamming. At the same time, the one-by-one pushing mode can only push out one structural part in a single movement, which is also convenient for the later clamping operation of the structural parts.

[0006] Further, in order to facilitate the rotation of the rotating arm and make the top convex plate move inward, the outer end of the top convex plate is in an outward convex arc structure.

[0007] Further, in order to improve the flexibility of the rotation of the rotating arm, a top push wheel is rotatably arranged at the inner end of the rotating arm. The outer circumference of the top push wheel is tangent to the outer end of the top convex plate.

[0008] Further, in order to limit the rotation angle of the rotating arm to ensure the normal progress of the pushing operation, a stop pin is installed on the upper mounting plate.

[0009] Further, when the rotating arm is pushed to rotate, the movable side plate is also prone to move forward. In order to prevent the movable side plate from moving forward and causing the movable insertion plate to be unable to be inserted between the structural members, top plates are respectively provided at both upper ends of the movable side plate. The outer ends of the top plates are formed with inclined surfaces. L-shaped plates are respectively installed on both sides of the concave member. A movable vertical rod is inserted through the upper end of the L-shaped plate. A limiting plate is provided at the lower end of the movable vertical rod. The lower end of the limiting plate is in a wedge-shaped structure. A restoring spring is sleeved on the lower end of the movable vertical rod. The restoring spring is located above the limiting plate.

[0010] The advantages of the above technical solution are as follows:

[0011] The utility model basically realizes the automatic pushing and feeding of structural members, and only one structural member can be pushed at a time during the pushing, thus facilitating the subsequent clamping operation of the structural members. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] As Figures 1 to 3As shown in the figure, a device for pushing metal structural parts includes a concave part 1. Rectangular holes 10 are provided on both sides of the concave part 1. A pair of guide rails 2 are installed on the outer wall of the concave part 1. A movable side plate 3 is movably arranged on the guide rails 2. A plurality of movable insertion plates 4 are inserted through the movable side plate 3. The movable insertion plates 4 are arranged in an equally spaced array. An inner top plate 40 is provided at the outer end of the movable insertion plate 4. A plurality of spring pins 41 are inserted through the inner top plate 40. The inner ends of the spring pins 41 are arranged on the movable side plate 3. A spring 42 is sleeved on the inner end of the spring pin 41. The spring 42 is located between the movable side plate 3 and the inner top plate 40. A top convex plate 43 is provided on the outer wall of the inner top plate 40. The outer end of the top convex plate 43 is of an outward convex arc structure. Mounting plates 44 are respectively installed on the upper and lower sides of the movable side plate 3. A side plate 45 is installed on the mounting plate 44. A movable hole 46 is provided on the side plate 45. A rotating arm 48 is swingably arranged in the movable hole 46. The rotating arm 48 is arranged on the side plate 45 through a pair of hinged convex plates 47. The inner end of the rotating arm 48 acts on the outer end of the top convex plate 43. Preferably, a top pushing wheel 49 is rotatably arranged at the inner end of the rotating arm 48. The outer circumference of the top pushing wheel 49 is tangent to the outer end of the top convex plate 43. A rocker 50 is provided at the outer end of the rotating arm 48. A mounting frame 51 is installed on the concave part 1. A cylinder 52 is installed on the mounting frame 51. A movable end plate 53 is installed at the movable end of the cylinder 52. A pair of movable arms 54 are installed at the lower end of the movable end plate 53. A kidney-shaped hole 55 is provided at the outer end of the movable arm 54. The upper end of the rocker 50 is inserted into the kidney-shaped hole 55. A stop pin is installed on the upper mounting plate 44.

[0017] Top plates 30 are respectively provided at the upper ends of both sides of the movable side plate 3. The outer ends of the top plates 30 are formed with inclined surfaces. L-shaped plates 31 are respectively installed on both sides of the concave part 1. A movable vertical rod 32 is inserted through the upper end of the L-shaped plate 31. A limit plate 34 is provided at the lower end of the movable vertical rod 32. The lower end of the limit plate 34 is of a wedge-shaped structure. A restoring spring 33 is sleeved on the lower end of the movable vertical rod 32. The restoring spring 33 is located above the limit plate 34.

[0018] In this embodiment, the feeding end of the device for pushing metal structural parts is connected to an automatic feeding device. The automatic feeding device arranges the structural parts neatly and can adjust the structural parts with incorrect postures into postures that can be directly clamped. Therefore, the postures of the structural parts entering the concave part 1 are consistent.

[0019] When pushing the structural member, the cylinder 52 is started. Driven by the cylinder 52, the movable arm 54 moves forward. When the movable arm 54 moves forward, the kidney-shaped hole 55 on it acts on the rocker 50, thereby causing the outer end of the rotating arm 48 to rotate forward. And when rotating, the inclined surface of the limit plate 34 acts on the inclined surface of the top plate 30. Therefore, at this time, the movable side plate 3 will not move forward. As the rocker 50 rotates, the push wheel 49 at the inner end of the rotating arm 48 acts on the top convex plate 43, thereby causing the movable side plate 3 to move inward, and causing the movable insertion plate 4 to be inserted between two adjacent structural members. Then, driven by the cylinder 52, the movable insertion plate 4 will move forward. As the movable insertion plate 4 moves, each structural member located in the concave member 1 will be pushed forward by a certain distance, and the structural member at the forward end will be pushed out. Then, the clamping operation of the structural member is carried out.
