DETAILED DESCRIPTION OF THE EMBODIMENTS
[0014] 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 of the embodiments. Based on the embodiments in 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.
[0015] Please refer to Figures 1-3 , the general performance of the existing chamfering equipment is poor and it cannot adapt to metal bars of different sizes. Therefore, a new type of bar chamfering device is designed, and the specific structure is as follows: It includes a base 1, and a plurality of guide posts 3 are fixedly connected to the top of the base 1. The tops of the guide posts 3 are jointly fixed with a top plate 4. An upper pressing module 7 and a lower pressing module 8 are arranged between the top plate 4 and the base 1. The guide posts 3 all slide through the upper pressing module 7 and the lower pressing module 8. The upper pressing module 7 is driven by an upper hydraulic cylinder 5 installed at the bottom of the top plate 4, and the lower pressing module 8 is driven by a lower hydraulic cylinder 6 fixed on the base 1. A plurality of metal bars 9 are jointly attached between the upper pressing module 7 and the lower pressing module 8. The two pressing modules are respectively driven by hydraulic cylinders to move up and down. When the metal bar 9 is located between them, the pressing modules initially clamp the metal bar 9.
[0016] A driving mechanism for driving the metal bar 9 to rotate is arranged in the lower pressing module 8. Grinding discs 2 are arranged at both ends of the metal bar 9, and the grinding discs 2 are installed above the base 1. After the metal bar 9 is clamped, the driving mechanism drives the metal bar 9 to rotate, and the two ends of the metal bar 9 are chamfered by the grinding discs 2.
[0017] When replacing the metal bar 9 with a shorter length, the two ends of the metal bar 9 cannot contact the grinding discs 2, and thus chamfering cannot be achieved. At this time, the upper hydraulic cylinder 5 and the lower hydraulic cylinder 6 move in coordination to lower the heights of the upper pressing module 7 and the lower pressing module 8. The tops of the two grinding discs 2 are inclined outward, so that the two ends of the metal bar 9 can contact the grinding discs 2.
[0018] Specifically, the upper pressing module 7 includes an upper frame body 71, and a plurality of rotatable upper roller bodies 72 are arranged in the upper frame body 71; the lower pressing module 8 includes a lower frame body 81, and a plurality of rotatable lower roller bodies 82 are arranged in the lower frame body 81. The lower roller bodies 82 are driven by a driving mechanism, and the lower roller bodies 82 and the upper roller bodies 72 are arranged in a staggered manner. The metal bar 9 is located in the triangular space between the lower roller bodies 82 and the upper roller bodies 72. The metal bar 9 is squeezed and clamped by the roller bodies. By driving the lower roller bodies 82 through the driving mechanism, the lower roller bodies 82 drive the metal bar 9 to rotate.
[0019] Among them, the driving mechanism includes a motor, a chain 84 and a sprocket 83. The end of the lower roller body 82 penetrates through the outer wall of the lower frame body 81 and is fixedly connected to the sprocket 83. The sprocket 83 is linked by the chain 84 and driven by the motor. The motor drives the chain 84 and the sprocket 83 to rotate.
[0020] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
