Description

Technical Field

[0001] The utility model relates to the technical field of aluminum profile processing, in particular to a fixing device for punching holes in aluminum profiles. Background Art

[0002] At present, due to the advantages of low density, light weight, strong corrosion resistance, good weather resistance, etc., aluminum profiles are widely used in the building materials industry and other industries. According to actual usage needs, multiple holes often need to be opened on each surface of the aluminum profile, and generally a punching device is used for punching.

[0003] During operation, the aluminum profile is fixed on the workbench with a fixing device, and then the punching machine is controlled to move to the corresponding position according to the position of the hole for punching.

[0004] However, the existing fixing device can only fix a single aluminum profile at a time. To fix multiple aluminum profiles, they need to be fixed one by one and cannot be fixed together simultaneously, thus affecting work efficiency. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a fixing device for punching holes in aluminum profiles, which has the advantage of facilitating the simultaneous fixing of multiple aluminum profiles.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions:

[0007] A fixing device for punching holes in aluminum profiles includes a mounting plate. Two parallel cross plates are fixedly connected to the upper part of the mounting plate. Four equally spaced baffle plates are fixedly connected between the two cross plates. The baffle plates are perpendicular to the cross plates and fixedly connected to the mounting plate. There are two clamping plates between adjacent two baffle plates. The clamping plates are slidably connected to the mounting plate. On one side of the clamping plate perpendicular to the mounting plate, a chute is opened. It further includes a hinge rod. One end of the hinge rod is embedded in the chute of the clamping plate, and the other end of the hinge rod is hinged to the cross plate. It also includes a cylinder fixedly connected to the lower part of the mounting plate. The cylinder is in transmission connection with the hinge rod through a transmission mechanism.

[0008] By adopting the above technical solution, the aluminum profile is placed between the two clamping plates between adjacent two baffle plates. The cylinder drives the hinge rod to rotate. The two hinge rods between adjacent two baffle plates rotate in opposite directions, thereby driving the two clamping plates between each two baffle plates to approach each other and clamp the aluminum profile to fix it, preventing the aluminum profile from moving when the punching machine punches, facilitating the simultaneous fixing of multiple aluminum profiles, and saving working time.

[0009] Preferably, the transmission mechanism includes a gear and a rack. The gear is located at the hinge joint of the articulated rod and the cross plate, and is fixedly connected to the articulated rod. The gear is located outside the cross plate. The output shaft of the cylinder is fixedly connected with a connecting plate, and the rack is fixedly connected with the connecting plate. The gear and the rack are meshed with each other. The two racks located between two adjacent backing plates are respectively located on different sides of the two gears meshed with them.

[0010] With the above technical solution, the cylinder drives the rack to move in the vertical direction, and the movement of the rack drives the gear meshed with it to rotate. The rotation directions of two adjacent gears are opposite, so that the rotation directions of two adjacent articulated rods are opposite.

[0011] Preferably, a rubber pad is fixedly connected to the surface of the clamping plate in contact with the aluminum profile.

[0012] With the above technical solution, the damage to the aluminum profile is reduced.

[0013] Preferably, a rotating shaft is rotatably connected to one end of the articulated rod connected to the clamping plate, and the rotating shaft is embedded in a sliding groove opened in the clamping plate.

[0014] With the above technical solution, the friction between the articulated rod and the clamping plate is reduced, and the articulated rod drives the clamping plate to move better.

[0015] Preferably, it further includes a sliding rod. The sliding rod is fixedly connected to the mounting plate. The clamping plate passes through the sliding rod, and the clamping plate is slidably connected to the sliding rod.

[0016] With the above technical solution, the clamping plate slides along the sliding rod. BRIEF DESCRIPTION OF THE DRAWINGS
