[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0031] Refer to Figure 1 - Figure 3, an embodiment provided by the present utility model: a preparation device for a vermicular graphite cast iron component of a robot, including a base 1. Multiple fixing holes are provided on the base 1. The moving plate 2 can be fixed by bolts, and at the same time, the position of the moving plate 2 can be adjusted to adapt to vermicular graphite cast iron components of different specifications. A moving plate 2 is fixedly installed at the top of the base 1. There are two sets of moving plates 2. A limiting plate 3 is arranged on the right side of the moving plate 2. A double-threaded screw rod 4 is rotatably connected to the inner wall of the limiting plate 3. A slider 5 is threadedly connected to the outer wall of the rear side of the double-threaded screw rod 4. By the combined use of the limiting plate 3, the double-threaded screw rod 4 and the slider 5, two clamping components can be driven to quickly clamp vermicular graphite cast iron components of different specifications. A clamping component is arranged on the right side of the slider 5. The clamping includes a limiting shell 61. The left side of the limiting shell 61 is fixedly connected to the right side of the slider 5. It is a fixed component that provides the framework and support for the clamping component. An extrusion belt 62 is fixedly installed at the front end of the limiting shell 61 through bolts. The extrusion belt 62 is made of rubber material and has a certain ductility. By the combined use with the compression spring 64 and the stabilizing rod 63, it can be attached to the outer wall of vermicular graphite cast iron components of different specifications, increasing the contact area and stability. A stabilizing rod 63 is fixedly installed at the rear side of the extrusion belt 62. The outer wall of the rear side of the stabilizing rod 63 is slidably connected to the inner wall of the limiting shell 61. The stabilizing rod 63 and the limiting shell 61 are elastically connected by a compression spring 64. When the extrusion belt 62 deforms, it drives the stabilizing rod 63 to slide on the inner wall of the limiting shell 61, squeezing the compression spring 64. Through the elastic force direction of the compression spring 64 acting on the extrusion belt 62, the extrusion belt 62 can closely adhere to the outer wall of vermicular graphite cast iron components of different specifications.
[0032] Referring to Figure 2 and Figure 3 , a sliding rod 65 is slidably connected to the inner wall of the limiting shell 61 near the right side of the stabilizing rod 63. A stabilizing plate 66 is fixedly connected to the left side of the sliding rod 65 near the bottom end of the stabilizing rod 63. The movement of the sliding rod 65 drives the stabilizing plate 66 to move. Anti-slip strips are provided on the inner wall of the top end of the stabilizing plate 66, which can increase the friction with the stabilizing rod 63, thereby improving the stability of the stabilizing rod 63. The inner wall of the top end of the stabilizing plate 66 slides on the bottom end of the stabilizing rod 63. The top end of the sliding rod 65 is hinged with a rotating column 67. A pull rod is fixedly connected to the rear side of the rotating column 67, which is convenient for the staff to rotate the rotating column 67. The sliding rod 65 is hinged at a position deviating from the center of the rotating column 67, so that when the rotating column 67 rotates, the sliding rod 65 can generate a vertical movement. A chute is provided at the top end of the limiting shell 61 near the bottom end of the rotating column 67. The chute is usually used to limit the movement range of the rotating column 67 to ensure the stability and safety when limiting the stabilizing rod 63. There are multiple sets of the stabilizing rod 63 and the compression spring 64, which further enhance the limitation of the extrusion belt 62, thereby improving the stability.
[0033] Referring to Figure 1 Figure 4 and Figure 5, a limiting component is arranged on the left side of the limiting plate 3. The limiting component includes a rotating rod 71. The right side of the rotating rod 71 is fixedly connected to the center of the left side of the limiting plate 3, which is used to limit the limiting plate 3 so that the clamping component can be adjusted in angle. A rotating handle 72 is fixedly connected to the middle of the left side of the rotating rod 71, which is convenient for the staff to rotate the clamping component. A sliding bead 73 is slidably connected to the inner wall of the right side of the rotating rod 71. The sliding bead 73 and the rotating rod 71 are elastically connected by a return spring 74. The sliding bead 73 is extruded by the elastic force of the return spring 74 so that the sliding bead 73 is fixed on the inner wall of the limiting groove 75, thereby limiting the rotating rod 71. There is no need to frequently replace the clamping tool or adjust the equipment, which not only saves time but also reduces the labor intensity of the workers. A limiting groove 75 is opened in the inner wall of the moving plate 2 near the right side of the rotating rod 71. The right side of the sliding bead 73 slides on the inner wall of the limiting groove 75. Multiple groups of sliding beads 73, return springs 74 and limiting grooves 75 are provided. The multiple groups of sliding beads 73, return springs 74 and limiting grooves 75 are evenly distributed along the center line of the rotating rod 71. The rotating rod 71 can be locked at multiple positions, thereby providing a wider position adjustment ability and a stronger locking effect.
[0034] Working principle: When in use, first place the robot vermicular graphite cast iron part to be processed between the two limiting shells 61. At this time, rotate the two double-threaded screws 4 to drive the sliders 5 to move on the inner wall of the limiting plate 3, drive the two limiting shells 61 to move towards each other, make the extrusion belt 62 contact with the vermicular graphite cast iron part, cause the extrusion belt 62 to deform, and at the same time the extrusion belt 62 drives the stabilizing rod 63 to slide on the inner wall of the limiting shell 61 and extrude the compression spring 64. When the clamping is completed, pull the pull rod to drive the rotating column 67 to slide on the inner wall of the chute, drive the sliding rod 65 to move upward, and make multiple groups of stabilizing plates 66 limit multiple groups of stabilizing rods 63, thereby limiting the shape of the extrusion belt 62 and making the extrusion belt 62 fit on the outer wall of the vermicular graphite cast iron part, increasing the contact area between the extrusion belt 62 and the vermicular graphite cast iron part, and thus improving the stability when clamping the vermicular graphite cast iron part.
[0035] When it is necessary to adjust the angle of the vermicular graphite cast iron part, the rotating handle 72 can be rotated to drive the rotating rod 71 to rotate on the inner wall of the moving plate 2. While the rotating rod 71 is rotating, multiple groups of sliding beads 73 slide out from the inner walls of multiple groups of limiting grooves 75, and at the same time multiple groups of return springs 74 are extruded, driving the sliding beads 73 to slide into the inner wall of the rotating rod 71. The sliding beads 73 are extruded by the elastic force of the return springs 74 so that the sliding beads 73 slide into the inner walls of the limiting grooves 75, thereby limiting the rotating rod 71 and at the same time limiting the angle of the limiting plate 3, and the angle adjustment of the clamped vermicular graphite cast iron part is completed.
[0036] Finally, it should be noted that the above are only preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
