Description

Technical Field

[0001] The utility model belongs to the technical field of steel pipe processing, and in particular relates to a steel pipe processing auxiliary device. Background Art

[0002] During the processing of steel pipes, it is generally necessary to fix the steel pipes in a fixed position to prevent the steel pipes from rolling due to external forces during processing, causing the processing surface to shift and affecting the processing effect.

[0003] Generally speaking, the clamps used in processing steel pipes mostly only fix one end of the steel pipe. However, some specific processing requires fixing both ends, such as truncation or welding and butting. In the prior art, the two-end fixing structures use independent clamps to complete the assembly limit, and there is no linkage function between the two. This not only increases the pre-processing operation process, but also during the steel pipe welding and butt processing, when the two sets of steel pipes are connected, there will be a certain difference in the axis positioning adjustment between the two sets of clamps, which affects the connection accuracy of the two sets of steel pipes.

[0026] The utility model provides a steel pipe processing auxiliary device, such as Figure 1-Figure 5 As shown, the steel pipe processing auxiliary device comprises:

[0027] A base 100, wherein a first limiting platform 210 and a second limiting platform 220 are provided on the base 100;

[0028] The main shaft 310, the first driving unit 320 and the second driving unit 330, several groups of the first driving units 320 and several groups of the second driving units 330 are arranged in the main shaft 310, two groups of the first driving units 320 and the second driving units 330 constitute a group of clamping units, and the first limiting platform 210 and the second limiting platform 220 are respectively provided with a group of clamping units;

[0029] In the present application, the first driving unit 320 includes a first rack 321, a first transmission wheel 322 and a first driving wheel 323, the first rack 321 and the first transmission wheel 322 are meshed with each other through a rack-and-gear structure, and the first transmission wheel 322 and the first driving wheel 323 are connected by gear meshing, and the second driving unit 330 includes a second rack 331 and a second driving wheel 332, and the second rack 331 and the second driving wheel 332 are meshed with each other through a rack-and-gear structure;

[0030] The first driving wheel 323 and the second driving wheel 332 are both arranged on the main shaft 310. The first driving wheel 323 and the second driving wheel 332 will respectively drive the first rack 321 and the second rack 331 to perform linear motion along with the rotation of the main shaft 310. A first transmission wheel 322 is arranged between the first rack 321 and the first driving wheel 323 as a transmission, so that the first rack 321 and the second rack 331 move in opposite directions. The first rack 321 and the second rack 331 are both provided with a limit clamping column. When the first rack 321 and the second rack 331 move, the limit clamping columns on the first rack 321 and the second rack 331 will approach each other to complete the clamping and positioning of the steel pipe.

[0031] A set of clamping units is composed of two sets of first drive units 320 and second drive units 330. The two sets of first drive units 320 and second drive units 330 cooperate to form a clamping effect on both sides of the steel pipe, and the three-point support structure is used to improve the limiting effect of the steel pipe.

[0032] The first limiting platform 210 and the second limiting platform 220 are far away from each other. During the processing, the first limiting platform 210 can independently fix the steel pipe, or form an integral body with the second limiting platform 220 to process the steel pipe. When the first limiting platform 210 and the second limiting platform 220 are fixed as a whole, the first limiting platform 210 and the second limiting platform 220 can be adjusted synchronously, reducing the fixed limiting adjustment structure and operation steps to improve the limiting effect;

[0033] For example, when cutting, the cut surface is placed between the first limit platform 210 and the second limit platform 220. When the cutting is completed, the first limit platform 210 and the second limit platform 220 will respectively fix and clamp the steel pipe into two sections, so as to avoid splashing due to lack of a fixing component at one end, thereby improving the safety during the processing;

[0034] As a preferred implementation in this embodiment, the first limit platform 210 and the second limit platform 220 have the same structure. Taking the first limit platform 210 as an example, the first limit platform 210 includes a top plate 211, a bottom shell 212 and a guide plate 213; the bottom shell 212 is composed of a horizontal chamber and a vertical chamber connected vertically, and the horizontal chamber and the vertical chamber form an inverted L-shaped structure. The guide plate 213 is arranged in the horizontal chamber, and the guide plate 213 divides the horizontal chamber into three sliding areas, namely the first sliding area, the second sliding area and the third sliding area. The top plate 211 is provided with a sliding guide groove adapted to the first sliding area, the second sliding area and the third sliding area; the first transmission wheel 322 of the first driving unit 320 is assembled through a rotating shaft provided on the side wall of the bottom shell 212. The above structural assembly methods and principles are all prior art and are not described in detail here.

[0035] The first driving unit 320 is respectively assembled in the first sliding area and the third sliding area located on both sides, and the second driving unit 330 is arranged in the second sliding area located in the center; in this embodiment, the guide plate 213 and the inner wall of the bottom shell 212 are provided with guide rails, and the first rack 321 and the second rack 331 are provided with guide grooves. During the movement of the first rack 321 and the second rack 331, the first rack 321 and the second rack 331 move along a straight line under the action of the guide rails and the guide grooves;

[0036] The first rack 321 and the second rack 331 are provided with a limit clamping column extending from the sliding guide groove to the outside of the first limit platform 210, and the second limit platform 220 adopts the same way to arrange the clamping unit;

[0037] As a preferred implementation in this embodiment, a driving motor 340 is further provided in the second limiting platform 220, and the driving motor 340 is connected to the main shaft 310 through a bevel gear. The driving motor 340 generates power to drive the clamping unit to move and serves as a limiting mechanism of the clamping unit.

[0038] In this embodiment, a sleeve connection is further provided between the first limit platform 210 and the second limit platform 220, and the spindle 310 extends from the second limit platform 220 to the first limit platform 210 through the sleeve; the side walls adjacent to the first limit platform 210 and the second limit platform 220 are arranged with a bearing structure for fixing the spindle 310, so that the spindle 310 can rotate when passing through the first limit platform 210 and the second limit platform 220 at the same time; the side walls adjacent to the first limit platform 210 and the second limit platform 220 are also equivalent to the support seat of the spindle 310, and the sleeve is wrapped around the outer side of the spindle 310 between the first limit platform 210 and the second limit platform 220 to prevent the rotating parts from being directly exposed to the outside;

[0039] As a preferred implementation in this embodiment, the end face of the first rack 321 away from the first transmission wheel 322 and the end face of the second rack 331 away from the second driving wheel 332 are located in the same plane, ensuring that the limit clamping column is located in the same plane, the limit clamping column has the same structure, and a triangular notch is provided on the limit clamping column for clamping the steel pipe, and the notch of the upper limit clamping column of the first rack 321 and the notch of the limit clamping column of the second rack 331 are arranged oppositely, that is, the notch of the upper limit clamping column of the first rack 321 faces the limit clamping column of the second rack 331, and the notch of the limit clamping column of the second rack 331 faces the upper limit clamping column of the first rack 321;
