Description

Technical Field

[0001] The invention relates to the technical field of welding, and in particular to a positioning device. Background Art

[0002] In the traditional welding process, especially when welding the circumferential seam between the drum skin and the plugging plate, it is difficult to ensure perfect cylindricality during the manufacturing process of the drum skin, which results in axial movement of the drum when it rotates on the roller frame during the welding process. This movement causes the position of the welding groove to move in the axial direction, which poses a challenge to the accuracy and stability of the welding work.

[0003] When the drum rotates on the roller frame, there will be axial movement. The author has to frequently adjust the telescopic arm position of the submerged arc welding machine to ensure that the welding gun can track the correct welding position to ensure the continuity and quality of welding. However, this frequent adjustment not only consumes a lot of time and labor, but also reduces the efficiency of welding work. In addition, due to the continuous movement of the drum during welding, the welding quality is also difficult to guarantee, because the weld may have defects such as incomplete penetration, pores, cracks, etc. due to the instability of the drum.

The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0026] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0027] Example 1, reference Figure 1 to Figure 2 , which is the first embodiment of the present invention, provides a positioning device, including a support frame 100, a roller 101 is arranged at the end of the support frame 100; a positioning mechanism 200, the positioning mechanism 200 is connected to the support frame 100, the positioning mechanism 200 includes a connecting component 201 and a limiting component 202 arranged on the connecting component 201, the connecting component 201 is used to be connected to the support frame 100, the limiting component 202 is connected to the connecting component 201, and the limiting component 202 is used to limit the axial movement position of the roller 101.

[0028] Specifically, an arc-shaped groove is provided at the end of the support frame 100, and a storage groove is provided in the arc-shaped groove.

[0029] It should be noted that the arc groove and the storage groove are arranged at the end of the support frame 100 in order to further enhance the stability of the roller 101 and reduce friction. The storage groove opened in the arc groove can accommodate a part of the roller 101 to provide additional support, and the multiple groups of first rollers arranged in the storage groove and the second rollers 102 arranged on both sides of the end of the support frame 100 work together to reduce the friction of the roller 101 when rolling, so that the roller 101 can rotate more smoothly during the welding process, reduce the error caused by friction, and improve the welding efficiency.

[0030] Among them, multiple groups of first rollers are arranged in the storage slot, and second rollers 102 are arranged on both sides of the end of the support frame 100;

[0031] The first roller and the second roller 102 are used to reduce the friction force when the drum 101 rolls.

[0032] Furthermore, a first connecting through hole is opened at the bottom end of the support frame 100, and the connecting assembly 201 is connected to the support frame 100 by a connecting bolt 103 passing through the first connecting through hole.

[0033] Example 2, reference Figure 1 to Figure 2 This embodiment is different from the first embodiment in that: the connecting assembly 201 includes a connecting rod 201a, a first cross bar 201b fixedly connected to the connecting rod 201a, and a first adjusting rod 201c connected to the first cross bar 201b; and a plurality of first adjusting holes are provided on the first adjusting rod 201c.

[0034] Specifically, a second connecting through hole is formed at one end of the connecting rod 201a away from the first cross bar 201b, and the connecting bolt 103 is adapted to the second connecting through hole.

[0035] It should be noted that the connecting rod 201a is the main part of the connecting assembly 201, which is directly connected to the support frame 100 and connected to the first adjustment rod 201c through the first crossbar 201b, forming a stable triangular structure to ensure the stability and strength of the connection; the first crossbar 201b is fixedly connected to the connecting rod 201a, providing additional support and stability, and the first adjustment rod 201c is connected to the first crossbar 201b, increasing the flexibility of adjustment;

[0036] The multiple groups of first adjustment holes on the first adjustment rod 201c are mainly used to adjust the position of the limit column 202a. The first adjustment holes allow the position of the limit column 202a to be changed by inserting the adjustment holes at different positions, so as to adapt to rollers 101 of different lengths, so that the positioning device can flexibly adapt to rollers 101 of different sizes, ensuring that the axial position of the roller 101 is accurately controlled during the welding process;

[0037] The second connecting through hole is provided at one end of the connecting rod 201a away from the first cross bar 201b, and its function is to connect the connecting component 201 with the support frame 100. The connecting bolt 103 is connected to the support frame 100 by passing through the second connecting through hole, so that the connecting component 201 can be firmly fixed on the support frame 100, and the possibility of quick disassembly and adjustment is provided. The matching design of the connecting bolt 103 and the second connecting through hole ensures the tightness and reliability of the connection, and prevents the loosening of the connecting component 201 due to vibration or external force during the welding process, thereby ensuring the stability and safety of the welding process.

[0038] The rest of the structure is the same as that of Example 1.

[0039] Example 3, reference Figure 1 to Figure 2 This embodiment is different from the above embodiments in that: the limiting assembly 202 includes a limiting column 202a arranged at the end of the connecting rod 201a, and a lifting column 202b plugged into the limiting column 202a; the limiting column 202a and the lifting column 202b cooperate to limit the axial position of the drum 101.

[0040] Specifically, the side wall of the limiting column 202a is provided with multiple groups of second adjustment holes, and the limiting column 202a and the lifting column 202b are each provided with two groups. The second cross bar 202c is fixedly connected between the two groups of limiting columns 202a, and the third cross bar 202d is fixedly connected between the two groups of lifting columns 202b.

[0041] Furthermore, a third roller 202e is provided at one end of the lifting column 202b away from the limiting column 202a, and a connecting hole is opened at one end of the lifting column 202b close to the limiting column 202a; a fourth roller 202f is provided on the third cross bar 202d, the connecting hole has the same diameter as the second adjustment hole, and the connecting hole and the second adjustment hole are connected by a first rotating bolt 202g.

[0042] Furthermore, a third connecting through hole is provided on the second cross bar 202c, the third connecting through hole has the same diameter as the first adjusting hole, and the third connecting through hole is connected to the first adjusting hole via a second rotating bolt 202h.

[0043] It should be noted that the second cross bar 202c fixedly connected between the two groups of limit posts 202a and the third cross bar 202d fixedly connected between the two groups of lifting posts 202b are used to enhance the stability of the limit assembly 202 and provide additional support, so that the limit assembly 202 is more stable when adjusting the position of the drum 101, and the displacement caused by vibration or external force during welding is reduced.

[0044] The rest of the structure is the same as that of Example 2.

[0045] Operation process: During the welding process, the roller 101 rotates around its center line to match the welding trajectory set by the automatic welding machine. Due to the inertia of welding and rotation during the welding process, the welded roller 101 will be axially offset and move, which requires the use of the positioning device invented by us.

[0046] When using the device, first place the support frame 100 at a suitable position, then place the roller 101 at the end of the support frame 100 by a crane, and then connect the positioning mechanism 200 according to the length and diameter of the roller 101;

[0047] When connecting the positioning mechanism 200, firstly, the connecting bolt 103 is connected to the first connecting through hole, so as to connect the support frame 100 to the connecting rod 201a, and then the position of the limiting column 202a at the end of the connecting rod 201a is adjusted according to the length of the roller 101. The specific operation is to insert the second rotating bolt 202h into the first adjusting hole at different positions of the first adjusting rod 201c to change the position of the third cross bar 202d at the end of the first adjusting rod 201c, thereby changing the position of the limiting column 202a at the end of the connecting rod 201a to adapt to rollers 101 of different lengths;

[0048] Next, according to the diameter of the drum 101, the distance between the limit column 202a and the lifting column 202b is adjusted. The specific operation is to insert the first rotating bolt 202g into the second adjustment hole of the lifting column 202b at different heights and connect it with the connecting hole at the end of the lifting column 202b, thereby changing the total height of the lifting column 202b and the limit column 202a to adapt to the drums 101 with different diameters in turn.

[0049] After the positions of the connecting rod 201a, the lifting column 202b and the support frame 100 are fixed in sequence, the welding work of the roller 101 can be carried out.

[0050] After the roller 101 is positioned, during welding, the welding posture of the welder is more comfortable, which simplifies and standardizes the welding work, reduces the labor intensity of the workers, and improves the welding quality and efficiency.

[0051] It should be noted that the positioning mechanism 200 in the present invention can also be used in conjunction with the positioning support in the prior art. The prerequisite for the positioning mechanism 200 to be used in conjunction with other devices is that the device can support the roller 101 and can reduce the friction generated when the roller 101 rotates, so that the roller 101 can rotate according to different welding points during welding.
