Description

Technical Field

[0001] The utility model relates to an energy-gathering pot rack welding tool, belonging to the technical field of gas stove production equipment. Background Art

[0002] In actual use, the existing gas stove is heated by placing the pot on the pot rack. Since there is a certain space between the pot and the burner, the heat energy generated by the gas combustion is not only used to heat the pot, but also a considerable amount escapes into the surrounding environment, causing energy waste. To solve this problem, a pot rack with a hollow internal structure of an energy-gathering ring has been developed. The energy-gathering ring directly forms a physical barrier between the flame and the outside air, thereby reducing the heat energy generated by the gas combustion from escaping outward, which can improve the thermal efficiency of the gas stove. The existing energy-gathering ring includes a top plate and a bottom plate distributed above and below. During production, the inner and outer edges of the top plate and the bottom plate are welded. The connection point of the energy-gathering ring of this structure is the inner and outer circumference of the two. The connection length is long, and it is easy to have incomplete welding, and the weld is obvious, affecting the appearance. In response to this, an energy-gathering ring made of two semi-annular hollow tubes connected and welded has been developed. For this purpose, special tooling is required to weld this energy-gathering pot rack. Summary of the Invention

The positioning mechanism contacts the two semi-annular hollow tubes in multiple directions so that the two semi-annular hollow tubes are placed in a fixed position on the bracket to form a ring shape. The clamping mechanism includes a number of driving mechanisms and clamping members. The clamping members are driven up and down by the driving mechanism to press the semi-annular hollow tubes formed in a ring shape onto the support seat, so that it flips together with the support seat.

[0005] Furthermore, the positioning mechanism includes a plurality of positioning members with arc-shaped grooves distributed along the circumference.

[0006] Furthermore, a first clamping mechanism is provided on the support seat, and the first clamping mechanism includes a plurality of first driving mechanisms and a first clamping member.

[0007] It further includes a limiting mechanism, which includes a pair of second driving mechanisms symmetrically arranged on both sides of the support seat, and a limiting member is provided on the second driving mechanism. The limiting member is moved by the second driving mechanism to form a ring-shaped connection between the two semi-annular hollow tubes to contact and cooperate to achieve limitation, and the contact point is located in the lower half of the semi-annular hollow tube.

[0008] Furthermore, the first pressing mechanism is vertically distributed with respect to the limiting mechanism.

[0012] The embodiment of the present utility model: Figure 1 As shown, a welding tool for an energy-gathering pot rack is used to weld two semi-annular hollow tubes 1 into a pot rack energy-gathering ring, including a bracket 2, a support seat 3, and a driving device 4. The driving device 4 includes a motor, a shaft coupling, etc. The support seat 3 is connected to the bracket 2 and driven by the driving device 4 to flip along the horizontal axis. A positioning mechanism and a pressing mechanism are provided on the support seat 3. The positioning mechanism includes a plurality of positioning members with arc grooves distributed along the circumference. The two semi-annular hollow tubes 1 are placed in the arc groove to form a ring shape.

The cylinder 6 is connected There is a clamping piece 7, which is moved up and down by the cylinder 6 to be pressed and matched with the semi-annular hollow tube 1. When in use, the two semi-annular hollow tubes 1 are horizontally placed on the support seat 3 to form a ring with several arc grooves 5 distributed along the circumference. The cylinder 6 contracts to press the clamping piece 7 downward to press the two semi-annular hollow tubes 1 onto the support seat 3. The six-axis manipulator equipped with a welding gun arranged next to the welding tool welds the upper half of the connection between the two semi-annular hollow tubes 1. The driving device 4 drives the support seat 3 to flip 180 degrees, and the six-axis manipulator equipped with a welding gun then welds the lower half of the connection to complete the production of the pot rack energy focusing ring.

The second cylinder 8 is provided with a first clamping member 9. When the first clamping member 9 is pushed out horizontally by the second cylinder, the two semi-annular hollow tubes 1 formed in a ring are tightened, so that the connection between the two annular hollow tubes 1 is tightly matched, thereby improving the quality of welding.

[0014] As a preferred embodiment, a limiting mechanism is included, which includes a pair of third cylinders 10 symmetrically arranged on both sides of the support seat 3. The third cylinder 10 is provided with a limiting piece 11. The two cylinders 8 are one, and are distributed 90 degrees apart from the pair of third cylinders 10. Before welding begins, the limiting pieces 11 on both sides are pushed out by the third cylinder 10 to tighten the connection between the two semi-annular hollow tubes 1 to form a ring, so that the two semi-annular hollow tubes 1 are aligned and not misaligned, and the support seat 3 will not rotate during the welding process. The contact and tightening position is located at the lower half of the semi-annular hollow tube 1, so that the upper half of the connection between the two semi-annular hollow tubes 1 can be welded. After turning 180 degrees, the unwelded lower half is at the top again, and then tightened and limited to achieve full welding of the connection.
