Description

Technical Field

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

[0002] Steel pipes with a hollow cross-section whose length is much greater than their diameter or circumference. They are categorized by cross-sectional shape into round, square, rectangular, and special-shaped steel pipes; by material, into carbon structural steel pipes, low-alloy structural steel pipes, alloy steel pipes, and composite steel pipes; by application, into pipes for pipelines, engineering structures, thermal equipment, the petrochemical industry, machinery manufacturing, geological drilling, and high-pressure equipment; and by production process, into seamless steel pipes and welded steel pipes. Seamless steel pipes are further categorized into hot-rolled and cold-rolled (drawn), while welded steel pipes are further categorized into straight seam welded pipes and spiral seam welded pipes. Positioning and clamping devices are required to secure steel pipes during processing.

[0003] The existing technology has the following deficiencies: the “steel pipe positioning and clamping device” disclosed in the prior art with publication number CN105127662A “comprises a bracket, a horizontal fixed platform provided on the bracket, a first limiting groove and a second limiting groove provided on the fixed platform, two screws provided on the bracket, the bottom ends of the screws being connected to a first positioning block and a second positioning block respectively, the first positioning block being located directly above the first limiting groove, and the second positioning block being located directly above the second limiting groove, a transport platform being provided on the side of the fixed platform, and the bottom end of the transport platform and the bottom end of the bracket being located on the same plane”;

[0004] The above structure can simultaneously clamp and fix two steel pipes through the steel pipe positioning clamping device, which can easily align the pipe ends of the two steel pipes and is easy to operate. However, this structure cannot adjust the position of the steel pipe after the position of the steel pipe is fixed. If the position of the steel pipe needs to be adjusted, the steel pipe needs to be removed again.

[0005] The existing technology has the following problems:

[0006] The current positioning and clamping devices used for steel pipe processing cannot subsequently adjust the position of the steel pipe after positioning and clamping the steel pipe. Therefore, the position of the steel pipe cannot be flexibly adjusted during the processing of the steel pipe, and the specific processing position cannot be accurately changed. Utility Model Content

[0007] In view of the deficiencies in the prior art, the utility model provides a positioning and clamping device for steel pipe processing, which solves the current problem that the position of the clamped steel pipe cannot be flexibly adjusted.

[0008] To achieve the above-mentioned object, the present invention provides the following technical solution: a positioning and clamping device for steel pipe processing, comprising a main frame, a positioning frame, and an adjusting shaft, wherein the positioning frame is arranged on the inner side of the main frame, the adjusting shaft is arranged on the side end of the positioning frame, an adjusting handle is connected to the outer end of the adjusting shaft, a connecting rod is arranged on the other side of the adjusting shaft, and a positioning clamp is connected to the end of the connecting rod;

[0009] The inner bottom end of the main frame is also provided with a side swing support mechanism, the bottom end of the positioning frame is fixedly connected with a connecting block, and the inner top end of the positioning frame is provided with a fixed axis rotating clamp;

[0010] The side-swing support mechanism also includes an axle column and an axle seat. The axle column runs through both ends of the side-swing support mechanism and the connecting block. There are two groups of axle seats, which establish a movable connection relationship with the axle column at both ends.

[0011] As an optimal technical solution of the present invention, the fixed-axis rotating clamp also includes a rotating shaft, a fastening bolt and a handle. The rotating shaft passes through the top of the positioning frame and extends downward to be fixedly connected to the fixed-axis rotating clamp. The fastening bolts are provided in four groups, which pass through the side wall of the fixed-axis rotating clamp from four different directions and establish a threaded connection relationship with it. The handle is fixedly connected to the other side end face of the rotating shaft.

[0012] As an optimal technical solution of the present invention, the adjusting shaft passes through one end of the side wall of the positioning frame and is equipped with a connecting rod. There is a threaded connection between the adjusting shaft and the side wall of the positioning frame. The adjusting handle, adjusting shaft, connecting rod, and positioning clamp are each provided in four groups and are symmetrically distributed with the middle part of the positioning frame as the axis.

[0013] As an optimal technical solution of the present invention, after the positioning frame as a whole completes the rotation adjustment through the side swing support mechanism, if continuous positioning is required, it needs to be assisted by an external bolt structure to fix the position, and the inner walls of the positioning frame and the main frame are both provided with a threaded groove structure.

[0014] As an optimal technical solution of the present invention, the left and right swing range of the side swing support mechanism is fixed, with a maximum angle of 75° on each side, and the main frame needs to be installed at a high position as a whole, with both left and right sides 30 cm above the horizontal plane.

[0015] As a preferred technical solution of the present invention, the side ends of the positioning clamp are further provided with four groups of open rectangular block structures, which are distributed in symmetrical positions.

[0016] As a preferred technical solution of the present invention, a bearing structure is further provided at the connection between the rotating shaft and the top of the positioning frame, and a bearing structure is also provided at the connection positions between the two ends of the shaft column and the shaft seat.

[0017] Compared with the prior art, the present invention provides a positioning and clamping device for steel pipe processing, which has the following beneficial effects:

[0018] This positioning and clamping device for steel pipe processing is provided with a side swing support mechanism, a fixed axis rotating clamp and a connecting block. When the device is used to position and clamp the steel pipe, the operator only needs to insert the steel pipe between the positioning clamps, and then extend it upward until it is inserted into the fixed axis rotating clamp. By holding the adjustment handle and rotating the adjustment shaft, the connecting rod drives the positioning clamp to move toward the steel pipe until the steel pipe is clamped to achieve the positioning effect. After the steel pipe is positioned, the positioning frame can be rotated and swung laterally with the shaft column as the axis. When swinging, the positioning frame will also drive the steel pipe to change from longitudinal to transverse. When the processing position of the steel pipe itself needs to be adjusted, the operator can tighten the four sets of fastening bolts to keep the steel pipe in a fixed position, and then rotate the adjustment shaft by rotating the adjustment handle in the opposite direction to move the connecting rod and the positioning clamp to both sides, loosening the clamping of the steel pipe. Then, the handle can be used to rotate the rotating shaft, and the rotating shaft drives the fixed axis rotating clamp to rotate. The steel pipe inside the fixed axis rotating clamp rotates with the fixed axis rotating clamp until it is adjusted to the appropriate position and the above steel pipe positioning and clamping steps are repeated. The above process can make the device have the following effects:

[0019] After the steel pipe is clamped by the device, it can be fixed and then rotated left and right by the side swing support mechanism. The side swing can change the overall position of the steel pipe from vertical to horizontal, and the position of the steel pipe itself can be adjusted by the fixed-axis rotating clamp to determine the specific processing position. The above settings enable the device to flexibly change the position of the steel pipe through dual-axis adjustment after clamping and positioning the steel pipe, so that the position of the steel pipe can be flexibly changed and the processing position is more precise.

The positioning frame 2 is arranged on the inner side of the main frame 1, and the positioning frame 2 carries the positioning structure of the steel pipe. The adjusting shaft 3 is arranged on the side end of the positioning frame 2. The adjusting shaft 3 cooperates with the adjusting handle 4, the connecting rod 5, and the positioning clamp 6 to clamp the steel pipe. The outer end of the adjusting shaft 3 is connected to the adjusting handle 4, and the other side of the adjusting shaft 3 is provided with a connecting rod 5. The end of the connecting rod 5 is connected to the positioning clamp 6.

[0027] The inner bottom end of the main frame 1 is also provided with a side swing support mechanism 7, which carries the rotation of the positioning frame 2. The bottom end of the positioning frame 2 is fixedly connected with a connecting block 8, which assists in the installation of the positioning frame 2. The inner top end of the positioning frame 2 is provided with a fixed axis rotating clamp 9, which rotates and adjusts the steel pipe.

[0028] The side swing support mechanism 7 also includes a shaft column 701 and a shaft seat 702. The shaft column 701 runs through both ends of the side swing support mechanism 7 and the connecting block 8. There are two groups of shaft seats 702, which establish a movable connection relationship with the shaft column 701 at both ends.

[0029] In this embodiment, the fixed-axis rotating clamp 9 also includes a rotating shaft 901, a fastening bolt 902 and a handle 903. The rotating shaft 901 passes through the top of the positioning frame 2 and extends downward to be fixedly connected to the fixed-axis rotating clamp 9. The fastening bolt 902 is provided with four groups, which penetrate the side wall of the fixed-axis rotating clamp 9 from four different directions and establish a threaded connection relationship with it. The handle 903 is fixedly connected to the other side end face of the rotating shaft 901; the adjusting shaft 3 passes through one end of the side wall of the positioning frame 2 and is installed with a connecting rod 5. There is a threaded connection relationship between the adjusting shaft 3 and the side wall of the positioning frame 2. The adjusting handle 4, adjusting shaft 3, connecting rod 5, and positioning clamp 6 are each provided with four groups, and are symmetrically distributed with the middle part of the positioning frame 2 as the axis. By setting four groups of symmetrically distributed adjusting handles 4, adjusting shafts 3, connecting rods 5, and positioning clamps 6, the stable clamping of the steel pipe can be ensured; the positioning frame 2 as a whole is supported by a side swing mechanism After the structure 7 completes the rotation adjustment, if continuous positioning is required, it needs to be assisted by an external bolt structure to fix the position. The inner walls of the positioning frame 2 and the main frame 1 are both provided with a threaded groove structure, and the reserved threaded groove structure can help fix the position of the positioning frame 2; the left and right swing range of the side swing support mechanism 7 is fixed, and the maximum angle is 75° on each side, and the main frame 1 needs to be installed in a high position as a whole, and both sides are 30 cm above the horizontal plane; the side end of the positioning clamp 6 is also provided with four groups of open rectangular block structures, which are symmetrically distributed.

By setting the bearing structure, the rotating structure can be better assisted to rotate.

[0030] The working principle and usage process of the present invention are as follows: when the device is used to clamp the steel pipe, the operator only needs to insert the steel pipe between the positioning clamps 6, and then extend it upward until it is inserted into the fixed-axis rotating clamp 9. By holding the adjusting handle 4 and rotating the adjusting shaft 3, the connecting rod 5 drives the positioning clamp 6 to move toward the steel pipe until the steel pipe is clamped to achieve the positioning effect. After the steel pipe is positioned, the positioning frame 2 can be rotated and swung laterally with the shaft column 701 as the axis. The positioning frame 2 will also drive the steel pipe to change from longitudinal to transverse during the swing. When the processing position of the steel pipe itself needs to be adjusted, the operator can tighten the four sets of fastening bolts 902 to keep the steel pipe fixed in position, and then rotate the adjusting shaft 3 by rotating the adjusting handle 4 in the opposite direction to move the connecting rod 5 and the positioning clamp 6 to both sides, loosening the clamping of the steel pipe. Then, the rotating shaft 901 can be rotated by the grip 903. The rotating shaft 901 drives the fixed-axis rotating clamp 9 to rotate, and the steel pipe inside the fixed-axis rotating clamp 9 rotates with the fixed-axis rotating clamp 9 until it is adjusted to the appropriate position and the above-mentioned steel pipe clamping steps are repeated.
