[0036] In one embodiment, a butt welding machine frame includes a base plate, two rotating shafts, two angle adjustment rotating plates, and two clamping mechanisms. The base plate is provided with two base plate rotation holes; the angle adjustment rotating plates are provided with rotating plate rotation holes, each rotating shaft passes through one of the rotating plate rotation holes and is disposed in one of the base plate rotation holes, and each of the angle adjustment rotating plates rotates around one of the rotating shafts; each clamping mechanism is disposed on one of the angle adjustment rotating plates, and each clamping mechanism is used to clamp a workpiece, wherein one of the clamping mechanisms moves on the corresponding angle adjustment rotating plate in the direction extending from a first straight line, the first straight line passing through the center point of one of the base plate rotation holes, and the other clamping mechanism moves on the corresponding angle adjustment rotating plate in the direction extending from a second straight line, the second straight line passing through the center point of the other base plate rotation hole.

[0037] like Figures 1 to 3As shown, an embodiment provides a butt welding machine frame 10 , which includes a base plate 100 , two rotating shafts 200 , two angle adjustment rotating plates 300 and two clamping mechanisms 400 . Two base plate rotation holes 101 are provided on the base plate 100; the angle adjustment rotating plate 300 is provided with a rotating plate rotation hole 301, each of the rotating shafts 200 passes through a rotating plate rotation hole 301 and is arranged in a base plate rotation hole 101, and each of the angle adjustment rotating plate 300 rotates around a rotating shaft 200; each of the clamping mechanisms 400 is arranged on a said angle adjustment rotating plate 300, and each of the clamping mechanisms 400 is used to clamp a workpiece, one of the clamping mechanisms 400 moves along the extension direction of the first straight line 20 on the corresponding said angle adjustment rotating plate 300, and the first straight line 20 passes through the center point of one of the base plate rotation holes 101, and the other clamping mechanism 400 moves along the extension direction of the second straight line 30 on the corresponding said angle adjustment rotating plate 300, and the second straight line 30 passes through the center point of another said base plate rotation hole 101. In this embodiment, the center point of the rotating plate rotation hole 301 and the center point of the bottom plate rotation hole 101 are both located on the axis of the rotating shaft 200 .

[0038] like Figures 1 to 4 As shown, the butt welding machine frame 10 and the butt welding machine device are shown in FIG. 1 , wherein the two angle adjustment rotating plates 300 on the bottom plate 100 of the butt welding machine frame 10 can rotate around a rotation axis 200 respectively, thereby driving the clamping mechanism 400 on the angle adjustment rotating plate 300 to rotate. When the two angle adjustment rotating plates 300 rotate a certain angle, the angle between the two angle adjustment rotating plates 300 is the angle between the first straight line 20 and the second straight line 30. When the clamping mechanism 400 clamps the pipe, the pipe on one clamping mechanism 400 is arranged in a direction parallel to the first straight line 20, and the pipe on the other clamping mechanism 400 is arranged in a direction parallel to the first straight line 20. The pipe fittings are arranged in a direction parallel to the second straight line 30, that is, the extension direction of the pipe fittings on one clamping mechanism 400 is parallel to the first straight line 20, and the extension direction of the pipe fittings on the other clamping mechanism 400 is parallel to the second straight line 30, so that the angle between the two pipe fittings is the angle between the first straight line 20 and the second straight line 30. When it is necessary to connect the two pipe fittings at a corner, the angle between the first straight line 20 and the second straight line 30 needs to be equal to the degree of the corner. The angle between the first straight line 20 and the second straight line 30 can be adjusted by rotating the two angle adjustment plates 300 to make it equal to the degree of the corner. The butt-jointed ends of the two pipe fittings are respectively cut into end faces inclined relative to the radial direction of the pipe fittings, and the sum of the inclination angles of the two inclined end faces of the two pipe fittings is equal to the supplementary angle of the corner. If the two angle adjustment plates 300 are in the initial position, that is, Figure 1The angle adjustment rotating plate 300 is shown in FIG. 3 . The angle between the first straight line 20 and the second straight line 30 is 180°, that is, the first straight line 20 and the second straight line 30 are collinear. At this time, if two pipes are to be welded so that the two pipes form a corner, the ends of the two pipes to be butted are cut so that the sum of the angles of the two inclined end faces of the two pipes is (180° - the corner). The pipes are clamped on the clamping mechanism 400, and then the angle adjustment rotating plate 300 is rotated so that the sum of the angles of the two angle adjustment rotating plates 300 is (180° - the corner). 0°-corner), at this time, the two inclined end faces of the two pipe fittings can be made parallel, and then the clamping mechanism 400 is moved to achieve the butt connection of the two inclined end faces, and the two pipe fittings can be butted together by performing a welding operation with a welding mechanism. At this time, the angle between the two pipe fittings is the above-mentioned corner, so the above-mentioned butt welding machine frame 10 and butt welding machine device can efficiently perform butt welding operations on two pipe fittings at various corners; in addition, since the above-mentioned butt welding machine frame 10 and butt welding machine device are lightweight and flexible in structure, they are convenient for on-site operations.

[0039] In one embodiment, a driving mechanism is provided on the base plate 100, and the driving mechanism is connected to at least one of the two angle adjustment rotating plates 300. The driving mechanism drives the angle adjustment rotating plates 300 to rotate around the rotating axis, thereby improving the degree of automation of the butt welding machine device.

[0040] In one embodiment, the angle adjustment rotating plate 300 is parallel to the base plate 100, so that the angle adjustment rotating plate 300 can rotate around the rotation axis 200 above the base plate 100. In one embodiment, the angle adjustment rotating plate 300 slides relative to the base plate 100 when rotating.

[0041] In order to accurately control the rotation angle of the angle adjustment rotating plate 300 and thus control the size of the angle between the first straight line 20 and the second straight line 30, in one embodiment, two arc-shaped angle scales 110 are provided on the base plate 100, and each of the arc-shaped angle scales 110 takes the center point of one of the base plate rotation holes 101 as the center of the circle; each of the angle adjustment rotating plate 300 is provided with a pointer 302, and each of the pointers 302 points to one of the arc-shaped angle scales 110; or, each of the angle adjustment rotating plate is provided with a arc-shaped angle scale, and each of the arc-shaped angle scales takes the center point of one of the rotating plate rotation holes as the center of the circle, and two pointers are provided on the base plate, and each of the pointers points to one of the arc-shaped angle scales, so that after the angle adjustment rotating plate rotates a certain angle, the pointer will also rotate a corresponding angle, and the supplementary angle of the sum of the angles rotated by the two pointers is equal to the angle between the first straight line and the second straight line, that is, the supplementary angle of the sum of the angles rotated by the two pointers is equal to the angle formed after the two pipes are connected. In one embodiment, Figures 1 to 3As shown, two arc-shaped angle scales 110 are provided on the base plate 100, and each of the arc-shaped angle scales 110 takes the center point of one of the base plate rotation holes 101 as its center; each of the angle adjustment rotating plates 300 is provided with a pointer 302, and each of the pointers 302 points to one of the arc-shaped angle scales 110, so that the pointer 302 can point to the scale and the degree of rotation of the pointer 302 can be observed more accurately.

[0042] In order to facilitate the adjustment of the two angles, the rotating plate 300 rotates to adjust the inclined end faces of the two pipes to be parallel to each other. In one embodiment, as shown in FIG. Figure 3 As shown, the angle adjustment rotating plate 300 includes a gear portion 310 and a mounting plate portion 320 connected to each other, the gear portion 310 opens the rotating plate rotation hole 301, the clamping mechanism 400 is arranged on the mounting plate portion 320, the gears of the two gear portions 310 are meshed with each other, the line connecting the center points of the two bottom plate rotation holes 101 is the center line, and the two angle adjustment rotating plates 300 are symmetrical about the perpendicular bisector of the center line. Since the gears of the two gear portions 310 rotate in unison, the two angle adjustment rotating plates 300 are always symmetrical about the perpendicular bisector of the center line when rotating, and rotating one angle adjustment rotating plate 300 can cause the other angle adjustment rotating plate 300 to rotate as well, and the rotation angles of the two angle adjustment rotating plates 300 are equal, so after measuring the angle of the corner, one angle adjustment rotating plate 300 can be rotated according to the calculated bisector angle. , so that the two angle adjustment rotating plates 300 can be moved from the initial position to the position where the included angle is equal to the corner; and the inclination angles of the two inclined end faces of the two pipe fittings can be controlled to be consistent, and the inclination angle of the inclined end face is equal to the complementary angle of the bisecting angle, so that the two inclined end faces of the two pipe fittings can be parallel butted, and a pipe can be cut according to the calculated bisecting angle, so that the included angle between the cutting line and the extension direction of the pipe is the bisecting angle, and the included angle between the cutting line and the radial direction of the pipe is the above-mentioned inclination angle, and the pipe is cut into the above-mentioned two pipe fittings, one of the pipe fittings is clamped on the clamping mechanism 400 of the mounting plate portion 320 of an angle adjustment rotating plate 300, and the other pipe fitting is rotated 180° around its own center line and clamped on the clamping mechanism 400 of the mounting plate portion 320 of an angle adjustment rotating plate 300, and then the two angle adjustment rotating plates 300 are rotated so that the cut end faces of the two pipe fittings are parallel to each other. In one embodiment, the driving mechanism is connected to one of the angle adjustment turn plates 300, and the driving mechanism drives the angle adjustment turn plate 300 to rotate around the rotation axis, thereby improving the degree of automation of the butt welding machine device, and only one angle adjustment turn plate 300 needs to be driven to rotate to make both angle adjustment turn plates 300 rotate.

[0043] In order to facilitate the stable rotation of the angle adjustment plate 300 and ensure that the two pipes can be accurately docked, in one embodiment, as shown in FIG. Figure 1 and Figure 5 As shown, the butt welding machine frame 10 also includes a pressure plate 500, which is provided with two pressure plate rotation holes 501. The pressure plate 500 is arranged on the base plate 100, and each of the rotating shafts 200 is sequentially penetrated by a pressure plate rotation hole 501, a rotating plate rotation hole 301 and a base plate rotation hole 101. A portion of each angle adjustment rotating plate 300 is sandwiched between the base plate 100 and the pressure plate 500. In this way, the angle adjustment rotating plate 300 is sandwiched between the pressure plate 500 and the base plate 100 and is pressed by the pressure plate 500, thereby ensuring that the angle adjustment rotating plate 300 can stably rotate around the rotating shaft 200 without up and down deviation and shaking. Therefore, it can be ensured that the two inclined end faces of the two pipes are parallel to each other after rotation without deviation. In one embodiment, the gear part 310 is sandwiched between the base plate 100 and the pressure plate 500.

[0044] In order to ensure that the pressing plate 500 is stably arranged on the base plate 100 so that the pressing plate 500 can stably press the angle adjustment rotary plate 300, in one embodiment, there is a gap between the pressing plate 500 and the base plate 100, and the butt welding machine frame 10 also includes a plurality of pressing plate 500 support pads, one end of the pressing plate 500 support pad abuts against the base plate 100, and the other end abuts against the pressing plate 500. In this embodiment, the thickness of the support pad relative to the base plate 100 is equal to the thickness of the angle adjustment rotary plate 300 relative to the base plate 100. Since a support pad of the same thickness as the angle adjustment rotary plate 300 is provided, the pressing plate 500 is parallel to the base plate 100, and the pressing plate 500 is stably connected to the base plate 100, so that the angle adjustment rotary plate 300 can be stably pressed. In one embodiment, as Figure 2 and Figure 5 As shown, the base plate 100 is provided with a plurality of base plate fixing holes 102, the pressure plate 500 is provided with a plurality of pressure plate fixing holes 502, and the support pad is provided with a support through-hole. Each of the pressure plate fixing holes 502, a support through-hole and a base plate fixing hole 102 are correspondingly connected. The butt welding machine frame 10 also includes a plurality of fixing parts, each of which is sequentially passed through a pressure plate fixing hole 502, a support through-hole and a base plate fixing hole 102, so that the pressure plate 500, the support pad and the base plate 100 are firmly connected, so that the pressure plate 500 is firmly set on the base plate 100.

[0045] In order to facilitate locking the angle adjustment rotating plate 300 after rotating to a predetermined angle, in one embodiment, as Figure 2 、 Figure 3 and Figure 4As shown, the bottom plate 100 is provided with two locking holes 103, and the angle adjustment rotating plate 300 is provided with an arc-shaped through hole 303. The arc of each of the arc-shaped through holes 303 is centered at the center point of the rotating plate rotation hole 301. Figure 1 and Figure 4 As shown, the butt welding machine frame 10 also includes a locking piece 600, each locking piece 600 passes through a circular arc through hole 303 and is arranged in one of the locking holes 103, and the exposed end of the locking piece 600 is provided with a pressing portion, which is movably abutted against the angle adjustment rotary plate 300. When the angle adjustment rotary plate 300 rotates around the rotating shaft 200, the side wall of the circular arc through hole 303 slides relative to the locking piece 600. In this way, after the angle adjustment rotary plate 300 rotates a predetermined angle, the pipe docking operation needs to be performed, so the angle adjustment rotary plate 300 needs to be locked to prevent it from rotating and affecting the accuracy of pipe docking. The locking piece 600 passes through the circular arc through hole and is arranged in the locking hole 103, and the pressing portion presses the angle adjustment rotary plate 300, so that the angle adjustment rotary plate 300 is fixed and cannot continue to rotate. In one embodiment, the inner wall of the locking hole 103 is provided with an internal thread, and the locking member 600 is provided with an external thread. The external thread cooperates with the internal thread, so that the locking member 600 is screwed into the locking hole 103, thereby allowing the locking member 600 to lock the angle adjustment rotating plate 300. In one embodiment, the arc-shaped through hole 303 is defined at the end of the angle adjustment rotating plate 300 away from the rotating shaft 200, and two locking holes 103 are respectively provided at the two ends of the base plate 100. In this way, in conjunction with the pressure plate 500, both ends of the angle adjustment rotating plate 300 can be limited, thereby allowing the entire angle adjustment rotating plate 300 to be more stably fixed.

[0046] In order to facilitate the movement of the clamping mechanism 400 on the angle adjustment rotating plate 300 along the extending direction of the first straight line 20 or the second straight line 30, in one embodiment, as shown in FIG. Figure 6As shown, the butt welding machine frame 10 also includes two sliding assemblies 700 and two guide rail assemblies 800, each of the guide rail assemblies 800 is arranged on one of the angle adjustment turn plates 300, and each of the sliding assemblies 700 is slidably arranged on one of the guide rail assemblies 800, the sliding direction of one of the sliding assemblies 700 is parallel to the first straight line 20, and the sliding direction of the other of the sliding assemblies 700 is parallel to the second straight line 30; each of the clamping mechanisms 400 is arranged on one of the sliding assemblies 700, so that the clamping mechanism 400 is arranged on the sliding mechanism and slides on the guide rail assembly 800 as the sliding mechanism, one clamping mechanism 400 slides along the direction parallel to the first straight line 20 with the sliding assembly 700, and the other clamping mechanism 400 slides along the direction parallel to the second straight line 30 with the sliding assembly 700.

[0047] In order to facilitate the setting of the clamping mechanism 400, in one embodiment, as Figure 6 and Figure 7As shown, the sliding assembly 700 includes a pushing block 710, a sliding block 720 and a fixed plate 730, and the guide rail assembly 800 includes a pushing rod 810 and a sliding rail 820, the pushing rod 810 and the sliding rail 820 are respectively arranged on the angle adjustment rotating plate 300, and the pushing rod 810 and the sliding rail 820 are spaced apart and parallel to each other.

In one embodiment, the bearing seamlessly abuts against the inner wall of the center hole.

[0050] A butt welding machine device comprises a welding mechanism and a butt welding machine frame 10 as described in any of the above embodiments.

[0051] The above-mentioned butt welding machine device includes a butt welding machine frame 10, and the two angle adjustment rotating plates 300 on the bottom plate 100 of the butt welding machine frame 10 can rotate around a rotation axis 200 respectively, thereby driving the clamping mechanism 400 on the angle adjustment rotating plate 300 to rotate. When the two angle adjustment rotating plates 300 rotate a certain angle, the angle between the two angle adjustment rotating plates 300 is the angle between the first straight line 20 and the second straight line 30; when the clamping mechanism 400 clamps the pipe fitting, the pipe fitting on one clamping mechanism 400 is arranged in a direction parallel to the first straight line 20, and the pipe fitting on the other clamping mechanism 400 is arranged in a direction parallel to the first straight line 20. The pipes are arranged in a direction parallel to the second straight line 30, that is, the extension direction of the pipe on one clamping mechanism 400 is parallel to the first straight line 20, and the extension direction of the pipe on the other clamping mechanism 400 is parallel to the second straight line 30. In this way, the angle between the two pipes is the angle between the first straight line 20 and the second straight line 30. When it is necessary to connect the two pipes at a corner, that is, the angle between the first straight line 20 and the second straight line 30 needs to be equal to the degree of the corner, the angle between the first straight line 20 and the second straight line 30 can be adjusted by rotating the two angle adjustment plates 300 to make it equal to the degree of the corner. The butt-jointed ends of the two pipes are respectively cut into end faces inclined relative to the radial direction of the pipes, and the sum of the inclination angles of the two inclined end faces of the two pipes is equal to the supplementary angle of the corner. If when the two angle adjustment rotating plates 300 are in the initial position, the angle between the first straight line 20 and the second straight line 30 is 180 degrees, that is, the first straight line 20 and the second straight line 30 are collinear, at this time, if two pipe fittings are to be welded so that the two pipe fittings form a corner, the ends of the two pipe fittings to be butted are cut so that the sum of the angles of the two inclined end faces of the two pipe fittings is (180 degrees - angle), the pipe fittings are clamped on the clamping mechanism 400, and then the angle adjustment rotating plates 300 are rotated so that the sum of the angles of rotation of the two angle adjustment rotating plates 300 is (180 degrees - angle), at this time, the two inclined end faces of the two pipe fittings can be made parallel, and then the clamping mechanism 400 is moved to achieve butt connection of the two inclined end faces, and the two pipe fittings can be butted by using the welding mechanism to perform welding operations. At this time, the angle between the two pipe fittings is the above-mentioned angle, so the above-mentioned butt welding machine frame 10 and butt welding machine device can efficiently perform butt welding operations on two pipe fittings with various angles.

[0052] In one embodiment, the welding mechanism includes an electric milling cutter and an electric heating plate, which are respectively arranged on the pressing plate 500. The electric milling cutter is set up to cut and smooth the end faces of the two pipe fittings, and the electric heating plate is set up to heat the end faces of the two pipe fittings. After the temperature reaches the requirement, the docking operation is performed, and the welding operation is completed after the voltage is stabilized and cooled.
