Description

Technical Field

[0001] This utility model belongs to the technical field of clamping devices, specifically relating to a clamping device for square and rectangular tubes. Background Technology

[0002] Rectangular or square tubes are hollow steel sections that are square or rectangular in shape, and are widely used in construction, machinery manufacturing, steel structures, automobiles, shipbuilding, power generation, agricultural greenhouses, and many other fields. During the welding process of rectangular or square tubes, they need to be positioned and clamped, so clamping devices for rectangular or square tubes are required.

[0003] In related technologies, rectangular tubes are generally clamped by adjusting the bolt heads of bolts fixed on both sides. However, this method requires adjusting the position of the bolts every time the material is loaded or unloaded, making the loading and unloading operation inconvenient. Utility Model Content

[0004] The purpose of this invention is to provide a clamping device for square and rectangular tubes, which solves the problem of inconvenient loading and unloading operations during the clamping process of square and rectangular tubes in the prior art.

[0005] Therefore, this utility model provides a clamping device for square and rectangular tubes, including: a fixed part and a movable part, the movable part being rotatably connected to the fixed part, a first clamping member being provided on one side of the fixed part, and a second clamping member being provided on one side of the movable part, the first clamping member being opposite to the second clamping member.

[0006] Preferably, the movable part and the fixed part are rotatably connected by a cylindrical pin.

[0007] Preferably, when the movable component rotates along the cylindrical pin until its top remains horizontal, a placement groove is formed between the movable component and the fixed component. The placement groove is used to place the rectangular tube.

[0008] Preferably, the fixed component has a first placement surface, and the movable component has a second placement surface.

[0009] Preferably, when the first placement surface is parallel to the second placement surface, the height of the first placement surface is higher than or equal to the height of the second placement surface.

[0010] Preferably, when the first placement surface and the second placement surface are not parallel, one end of the second placement surface is higher than the height of the first placement surface.

[0011] Preferably, the first clamping member is an adjusting bolt, and the first clamping member is connected to the fixing component by a thread.

[0012] Preferably, the first clamping member is fastened to the side wall of the fixing member by a first nut.

[0013] Preferably, the second clamping member is an adjusting bolt, and the first clamping member is connected to the movable part by a thread.

[0014] Preferably, the second clamping member is fastened to the side wall of the movable part by a second nut.

[0015] Beneficial effects:

[0016] 1. This utility model provides a clamping device for square and rectangular tubes. By rotating the movable part and the fixed part, the positions of the first clamping member and the second clamping member can be adjusted to facilitate the loading and unloading of square and rectangular tubes. At the same time, before the material is unloaded, one end of the second placement surface is higher than one end of the first placement surface. After the square and rectangular tube is placed, the square and rectangular tube will press down on the second placement surface, causing the movable part to rotate and automatically clamp the square and rectangular tube.

[0017] 2. The clamping distance can be adjusted by the first clamping member and the second clamping member, so that it can be used to clamp square and rectangular tubes of different sizes. Attached Figure Description

[0021] The following detailed description of preferred embodiments of the present invention, along with the included examples, will make the content of the present invention more readily understood. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. In case of any conflict, the definitions in this specification shall prevail.

[0022] Example 1:

[0023] To complete, such as Figure 1The clamping device for a rectangular tube, as shown, includes a fixed component 1 and a movable component 2. The movable component 2 is rotatably connected to the fixed component 1 via a cylindrical pin 3. A first clamping member 4 is provided on one side of the fixed component 1, and a second clamping member 5 is provided on one side of the movable component 2, with the first clamping member 4 and the second clamping member 5 facing each other. When the movable component 2 rotates along the cylindrical pin 3 until its top remains horizontal, a placement groove is formed between the movable component 2 and the fixed component 1. The placement groove is used to place the rectangular tube.

[0024] The fixed component 1 has a first placement surface 11, and the movable component 2 has a second placement surface 21. When the first placement surface 11 is parallel to the second placement surface 21, the first placement surface 11 is higher than or equal to the height of the second placement surface 21. When the first placement surface 11 is not parallel to the second placement surface 21, one end of the second placement surface 21 is higher than the height of the first placement surface 11.

[0025] The first clamping member 4 is an adjusting bolt, and it is threadedly connected to the fixed part 1. The first clamping member 4 is fastened to the side wall of the fixed part 1 by the first nut 6. The second clamping member 5 is an adjusting bolt, and it is threadedly connected to the movable part 2. The second clamping member 5 is fastened to the side wall of the movable part 2 by the second nut 7.

[0026] Working principle: When no rectangular tube is placed, the movable part 2, being heavier at the end near the second clamping member 5, rotates around the cylindrical pin, causing the end of the second placement surface 21 away from the second clamping member 5 to be higher than the first placement surface 11. After the rectangular tube is placed, it presses down the second placement surface 21, and the movable part 2 rotates to bring the second clamping member 5 closer to the rectangular tube. The positions of the first clamping member 4 and the second clamping member 5 are adjusted to clamp the rectangular tube. After processing, the rectangular tube is lifted upwards, and the movable part 2, no longer constrained by the weight of the rectangular tube, rotates again to move the second clamping member 5 away from the first clamping member 4. When clamping rectangular tubes of the same size again, it is only necessary to place or lift the rectangular tube in the placement slot, facilitating the clamping of the rectangular tube.
