[0028] In the prior art, when welding the first box column and the second box column, a fixing plate is first welded to the first box column and the second box column to temporarily fix the first box column and the second box column, and then the fixing plate is polished after the first box column and the second box column are welded. However, this method is complicated to operate, and the welding and polishing workloads are large, resulting in low efficiency in welding the first box column and the second box column.

[0029] In order to solve the above problem, this embodiment provides a fixing device for fixing the first box-type column and the second box-type column. Figure 1 is a side view of a fixing device provided by an embodiment of the utility model, Figure 2 2 is a top view of the fixing device provided by the embodiment of the utility model. Figure 1 and Figure 2 The fixing device includes a clamp mechanism and a connecting assembly 30. The clamp mechanism includes a first clamp assembly 10 and a second clamp assembly 20. The first clamp assembly 10 is used to clamp the first box-type column, and the second clamp assembly 20 is used to clamp the second box-type column. The connecting assembly 30 is detachably connected to the first clamp assembly 10 and the second clamp assembly 20, and is used to fix or separate the first box-type column and the second box-type column along the axial direction of the first box-type column. The connecting assembly 30 is arranged on the clamp mechanism. When in use, the clamp mechanism is locked to clamp the first box-type column and the second box-type column. After the first box-type column and the second box-type column are welded, the clamp mechanism can be opened, which makes welding the first box-type column and the second box-type column easier and improves the efficiency of welding the first box-type column and the second box-type column.

[0030] In order to facilitate the connection of the connecting component 30 to the first clamp component 10 and the second clamp component 20, a first ear plate 11 is provided on the side wall of the first clamp component 10, and a second ear plate 21 is provided on the side wall of the second clamp component 20. The connecting component 30 can connect the first ear plate 11 and the second ear plate 21 to connect the first clamp component 10 and the second clamp component 20, thereby fixing the first box-type column and the second box-type column.

[0031] Specifically, the first clamp assembly 10 is provided with at least one pair of first ear plates 11 along a first direction, and the second clamp assembly 20 is provided with at least one pair of second ear plates 21 along a first direction, and the first direction intersects with the axial direction of the first box type; one of the at least one pair of first ear plates 11 is arranged opposite to one of the at least one pair of second ear plates 21 along a second direction, and the other of the at least one pair of first ear plates 11 is arranged opposite to the other of the at least one pair of second ear plates 21 along the second direction, and the second direction is parallel to the axial direction of the first box type.

[0032] In this embodiment, the first ear plate 11 and the second ear plate 21 are both vertically arranged on the side walls of the first clamp assembly 10 and the second clamp assembly 20. In other embodiments, the first ear plate 11 and the second ear plate 21 can also be fitted with the side walls of the first clamp assembly 10 and the second clamp assembly 20.

[0033] In order to make the connection assembly 30 more stable in connecting the first clamp assembly 10 and the second clamp assembly 20, the connection assembly 30 includes a first connection portion 31 and a second connection portion 32, which are clamped on both sides of the first ear plate 11 and the second ear plate 21 arranged opposite to each other along the second direction, and fixed by a first fixing member 40. In this embodiment, the first connection portion 31 and the second connection portion 32 can both adopt connection plates, and the connection plates are arranged on both sides of the first ear plate 11 and the second ear plate 21, so as to avoid the first box column being displaced when welding the first box column and the second box column, resulting in insufficient connection force of a single connection plate and thus breaking.

[0034] Specifically, four first ear plates 11 and four second ear plates 21 are provided, and they are arranged opposite to each other in pairs. Three second through holes are provided on each first ear plate 11 and second ear plate 21, and the remaining first through holes, third through holes and first fixing member 40 are provided with corresponding numbers. In this embodiment, the first fixing member 40 is provided as a bolt and nut assembly, a first through hole is provided on the first connecting portion 31, a second through hole is provided on the first ear plate 11, and a third through hole is provided on the second connecting portion 32. The bolts pass through the first through hole, the second through hole and the third through hole in sequence and are screwed with the nuts to fix the first connecting portion 31 and the second connecting portion 32 to the two sides of the first ear plate 11. The method of fixing the first connecting portion 31 and the second connecting portion 32 to the two sides of the second ear plate 21 is also the same, which will not be repeated here.

[0035] Further, the first clamp assembly 10; and / or, the second clamp assembly 20 is set as a split structure. The first clamp assembly 10 and the second clamp assembly 20 are both formed by the sub-clamp assembly. In this embodiment, the first clamp assembly 10 and the second clamp assembly 20 are set as a pair of clamps. In other embodiments, when the volume of the workpiece to be fixed is large, more than two sub-clamps can be spliced ​​to meet the fixing requirements. The sub-clamp includes a first abutment plate 121 and two second abutment plates 122 arranged oppositely, the first abutment plate 121 is connected between the two second abutment plates 122, and the two sub-clamps are enclosed to form a square clamp space. In this embodiment, the first clamp 12 and the second clamp 13 both include a first abutment plate 121 and two second abutment plates 122, the two second abutment plates 122 are arranged oppositely and vertically on the first abutment plate 121, and the ends of the four second abutment plates 122 abut against each other to form a square clamp space. In other embodiments, the first clamp 12 and the second clamp 13 can be both configured as two mutually perpendicular abutment plates. When the two abutment plates are placed at right angles to each other and the ends of the two abutment plates are vertically connected to each other, a square clamp space can also be formed.

[0036] Furthermore, the sub-hoop also includes a fixing ear plate 50 and a second fixing member 60, the fixing ear plate 50 is connected to the end of the second abutment plate 122 away from the first abutment plate 121, and the second fixing member 60 clamps the first box-type column by fixing the two fixing ear plates 50. In this embodiment, the second fixing member 60 is also configured as a bolt and nut assembly, and a plurality of fixing ear plates 50 are provided with fourth through holes, and the bolts pass through two opposite fourth through holes and are screwed with nuts to fix the first hoop 12 and the second hoop 13.

[0037] In order to lock the first box column and the second box column, the sub-hoop further includes a reinforcing portion 70, which is disposed between the second abutting plate 122 and the fixed ear plate 50. In this embodiment, the reinforcing portion 70 is configured as a triangular plate, which can support the fixed ear plate 50 and prevent the fixed ear plate 50 from being deformed by impact when the first box column and the second box column are displaced. Further, a plurality of reinforcing portions 70 are disposed at intervals along the axial direction of the sub-hoop.

[0038] When the connection assembly 30 is connected to the first clamp assembly 10 and the second clamp assembly 20, the first clamp assembly 10 and the second clamp assembly 20 are spaced apart along the axial direction of the first box-type column, so as to facilitate welding of the first box-type column and the second box-type column along the axial direction of the first box-type column.

[0039] In order to increase the locking force of the first clamp assembly 10 and the second clamp assembly 20 on the first box-type column and the second box-type column, a flexible anti-skid member 80 is provided on the inner side of the first clamp assembly 10 and the second clamp assembly 20. Specifically, the flexible anti-skid member 80 can be provided as a rubber pad, which increases the friction between the clamp mechanism and the first box-type column and the second box-type column, so that the clamp mechanism can more stably fix the first box-type column and the second box-type column.

[0040] When the fixing device provided in this embodiment is used, the second fixing member 60 is used to lock the fixing ear plate 50 to hold the first box-type column and the second box-type column tightly. After the first box-type column and the second box-type column are docked, the first fixing member 40 is used to fix the first connecting portion 31 and the second connecting portion 32 to the first ear plate 11, so that the first clamp assembly 10 and the second clamp assembly 20 are fixed, thereby fixing the first box-type column and the second box-type column. After the first box-type column and the second box-type column are welded, the clamp mechanism can be opened by loosening the first fixing member 40 and the second fixing member 60. The fixing device provided in this embodiment makes welding the first box-type column and the second box-type column easier and improves the efficiency of welding the first box-type column and the second box-type column.
