Clamping device for reinforcement cross beam

Abstract

The invention discloses a clamping device for a reinforcement cross beam and relates to a clamping fixture. The clamping device for the reinforcement cross beam comprises a base and at least two clamping mechanisms arranged side by side. Each clamping mechanism comprises a clamping jaw, an ejector rod, a linkage rod and a drive screw. A beam fixed to the base is further arranged on the base. One end of each clamping jaw is hinged to the beam. The middle of each clamping jaw is provided with a pressing block. The other end of each clamping jaw is provided with a U-shaped opening. The base is further provided with an upward protruding edge. The protruding edge is opposite to the beam. The linkage rods are vertically connected with the protruding edge in a sliding manner. The ejector rods are horizontally connected with the protruding edge in a sliding manner. The wedge surfaces of the linkage rods are matched with the wedge surfaces of the ejector rods. The drive screws are hinged to the upper ends of the linkage rods and connected with handles in a threaded manner respectively. The drive screws can be clamped into the U-shaped openings in the corresponding clamping jaws. The clamping device is used for clamping the reinforcement cross beam and guaranteeing the straightness of the reinforcement cross beam.

Description

technical field [0001] The invention relates to a clamping fixture, in particular to a clamping device for reinforcing a beam. Background technique [0002] In order to improve the loading capacity and safety of the car, there are always many reinforcement devices on the car, such as reinforcement plates, bumpers, and guardrails; and in the carrier car, reinforced beams can be seen everywhere, because the carrier car is usually spliced ​​by steel plates. Therefore, in order to ensure the straightness of the steel plate, the reinforced beam is usually welded on the steel plate; the reinforced beam not only plays the role of strengthening, but also sometimes plays the role of suspension, such as the installation of car lights and the installation of spreaders; the reinforced beam Because it is longer, it is more likely to be warped when the steel plate is combined with other reinforced beams. Therefore, when drilling the reinforced beams, in order to make the holes accurate, i...

[0002] In order to improve the loading capacity and safety of the car, there are always many reinforcement devices on the car, such as reinforcement plates, bumpers, and guardrails; and in the carrier car, reinforced beams can be seen everywhere, because the carrier car is usually spliced ​​by steel plates. Therefore, in order to ensure the straightness of the steel plate, the reinforced beam is usually welded on the steel plate; the reinforced beam not only plays the role of strengthening, but also sometimes plays the role of suspension, such as the installation of car lights and the installation of spreaders; the reinforced beam Because it is longer, it is more likely to be warped when the steel plate is combined with other reinforced beams. Therefore, when drilling the reinforced beams, in order to make the holes accurate, it is necessary to ensure that the reinforced beams are straight when drilling; and now The fixing method when drilling the reinforced beam is the same as the fixing method when welding the reinforced beam. They are all fixed by spot welding. Spot welding; this method is not only time-consuming and laborious, but also needs to knock off the spot welding slag when loosening the reinforcing beam, thereby deforming the reinforcing beam
