Description

Technical Field

[0001] The utility model relates to the technical field of electric control cabinet processing, in particular to a positioning frame for riveting. Background Art

[0002] The electric control cabinet frame consists of an internal skeleton 1 and an external protective shell, and the external protective shell is composed of multiple plates 2. The external protective shell is fixed to the skeleton by welding or riveting. Since the position of the welding points is inconvenient to process during welding, the riveting method is mostly adopted. During riveting, the operator first presses the plate 2 tightly against the skeleton and aligns the pre-drilled holes, and then performs the riveting operation. During the riveting process, one operator needs to keep positioning the plate 2, while the other performs the riveting operation. However, during the positioning process, due to the shaking of the operator and other reasons, it will affect the riveting operation, and the operation is quite difficult.

[0016] Figure 3 The enlarged view of part B is shown. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] As Figures 1 to 3 shown, a positioning frame for riveting includes two pairs of support legs 3. The support legs 3 are symmetrically arranged in pairs. A cross plate 30 is provided at the upper end of the support legs 3 on the same side. A connecting head 31 is provided at the inner side of one end of the cross plate 30. A rotating block 32 is rotatably provided at the inner end of the connecting head 31. A lead screw 33 is provided on the rotating block 32. A rotating cap 34 is provided at the outer end of the lead screw 33. In some other embodiments, the lead screw 33 is rotatably provided on the rotating block 32. An L-shaped top plate 35 is threadedly connected to the lead screw 33. The inner end of the L-shaped top plate 35 is in an arc structure.

[0018] At the other end of the cross plate 30, there is a connecting plate 36. At the inner end of the connecting plate 36, there is a positioning back plate 4. Four rotating columns 40 are rotatably arranged on the positioning back plate 4. An eccentric chuck 41 is arranged at the inner end of the rotating column 40. At the outer end of the rotating column 40, there is a pulling arm 42. A kidney-shaped hole 43 is opened at the inner end of the pulling arm 42. A convex plate 48 is arranged on the outer wall of the positioning back plate 4. A pair of guide rods 47 are arranged on the convex plate 48. Movable plates 46 are respectively sleeved at both ends of the guide rod 47. A spring 49 is arranged between the movable plate 46 and the convex plate 48. The spring 49 is sleeved on the guide rod 47. Rotating heads 50 are respectively arranged at the upper and lower ends of the outer wall of the positioning back plate 4. An inner top rotating plate 51 is rotatably arranged at the outer end of the rotating head 50. The inner end of the inner top rotating plate 51 is of an arc structure. The screw rod 33 is rotatably arranged on the rotating block 32. An L-shaped top plate 35 is threadedly connected to the screw rod 33. The inner end of the inner top rotating plate 51 acts on the outer wall of the movable plate 46. A transverse arm 45 is arranged at the inner end of the movable plate 46. Acting rods 44 are respectively arranged at both ends of the transverse arm 45. The acting rods 44 pass through the kidney-shaped hole 43.

[0019] During the operation of this embodiment, the positioning frame is transferred to the inner skeleton 1, and the cross plate 30 is located on both sides of the inner skeleton 1.

[0020] Then the operator places the plate 2 between the chucks 41.

[0021] Then the operator rotates the two inner top rotating plates 51 so that the inner end of the inner top rotating plate 51 acts on the movable plate 46, causing the movable plate 46 to move towards the convex plate 48 and compressing the spring 49. When the movable plate 46 moves inwards, it will cause the transverse arm 45 to move, and as the transverse arm 45 moves, it will cause the acting rod 44 to act on the kidney-shaped hole 43, and then the pulling arm 42 will rotate, further causing the chuck 41 to rotate, and the outer periphery of the chuck 41 will position both sides of the plate 2. At this time, the plate will be fixed on the positioning frame.

[0022] Then the operator rotates the L-shaped top plate 35 so that its length direction is parallel to the length direction of the cross plate 30, and then rotates the screw rod 33 to move the plate 2 closer to one side of the inner frame 1.

[0023] Finally, the operator performs the riveting and positioning operation on the plate 2 and the inner frame 1.

[0024] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalent technologies, the present invention also intends to include these modifications and variations.
