DETAILED DESCRIPTION

[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0025] like Figures 1 to 6 As shown, the present invention provides an auxiliary device for welding processing, including a support frame and a positioning clamping mechanism.

[0026] The support frame includes a base 101 for placing an annular steel plate 10, and an annular steel cylinder 20 is placed on the annular steel plate 10;

[0027] The positioning and clamping mechanism includes a driving plate 201 driven to rise and fall by a power mechanism. The support frame also includes a mounting plate (not shown) mounted above the base 101, and the power mechanism is a cylinder 205 mounted on the mounting plate, and the driving plate 201 is connected to the bottom of the cylinder 205.

[0028] The lower part of the driving plate 201 is connected to a guide plate 204 which can be mounted on the base 101 via a return spring 202.

[0029] A guide rod 213 is disposed on the surface of the guide plate 204 , a guide groove 214 capable of vertically sliding through the guide rod 213 is disposed on the driving plate 201 , and the return spring 202 is sleeved on the outer side of the guide rod 213 .

[0030] The base 101 is provided with a positioning groove 103 , and the bottom of the guide plate 204 can be clamped on the positioning groove 103 , and the diameter of the guide plate 204 is smaller than the inner diameter of the annular steel plate 10 .

[0031] The outer side of the guide plate 204 is connected to a lateral pressure plate 206 via a compression spring 203. In the embodiment of the present invention, a slide groove 215 is provided around the guide plate 204, and a sliding sleeve 216 capable of sliding along the corresponding side of the slide groove 215 is provided on the inner side of the lateral pressure plate 206, and the compression spring 203 is provided inside the slide groove 215 and the sliding sleeve 216.

[0032] A limiting plate 207 with a limiting groove 208 opened outward is installed on the outer side of the lateral pressure plate 206 .

[0033] The limiting plate 207 is located above the surface height of the annular steel plate 10 , and the width of the limiting plate 207 is smaller than the width of the reinforcing plate 30 , so as to avoid the limiting plate 207 blocking the welding position.

[0034] The driving plate 201 is provided with a driving member, and the driving member is provided with a feeding trough 210 for vertically feeding the reinforcing plate 30. When the driving member acts on the inner wall of the lateral pressing plate 206, the lateral pressing plate 206 can move toward the outside. Specifically:

[0035] The driving member is a wedge-shaped connecting plate 209 installed on the driving plate 201 and extending upward from the inside to the outside. The feeding trough 210 is opened on the wedge-shaped connecting plate 209, and the feeding trough 210 can be vertically opposite to the limiting groove 208 on the corresponding side below. The inner side of the top end of the lateral pressure plate 206 is provided with a wedge-shaped surface 212 that cooperates with the wedge-shaped connecting plate 209.

[0036] The driving plate 201 is also connected to a pressing plate 211 , and the pressing plate 211 can press on the top surfaces of the annular steel cylinder 20 and the reinforcing plate 30 .

[0037] The working principle of the device of the present invention is:

[0038] The annular steel plate 10 is placed roughly in the center on the base 101 , and the annular steel cylinder 20 is placed roughly in the center on the annular steel plate 10 .

[0039] Afterwards, the cylinder 205 is started to drive the plate 201 downward, and the guide plate 204 below the driving plate 201 connected by the return spring 202 sinks into the positioning groove 103 on the base 101 .

[0040] At this time, the lateral pressure plate 206 slidably mounted on the guide plate 204 is located inside the inner wall of the annular steel plate 10 .

[0041] The driving plate 201 is further driven downward, and the wedge-shaped connecting plate 209 moves the wedge-shaped surface 212 thereof to the lateral pressure plate 206 to be limited to the limiting groove 208 formed by the limiting plate 207 outside the lateral pressure plate 206, so that the reinforcing plate 30 is placed, which will at least partially overlap the surface of the inner edge plate 11 of the annular steel plate 10.

[0042] Next, the reinforcing plate 30 is vertically dropped from the feeding slot 210 of the wedge-shaped connecting plate 209 , and the reinforcing plate 30 will fall into the limiting slot 208 between the limiting plates 207 , and the bottom of the reinforcing plate 30 will overlap the surface of the inner edge plate 11 , thus completing the loading of the reinforcing plate 30 .

[0043] Finally, the driving plate 201 is further pressed downward, and the wedge-shaped connecting plate 209 connected to the driving plate 201 will squeeze the wedge-shaped surface 212, so that the lateral pressure plate 206 moves along the guide plate 204 toward the inner wall of the annular steel cylinder 20. On the one hand, it can drive the reinforcing plates 30 between the limiting grooves 208 to be supported on the inner wall of the annular steel cylinder 20, thereby completing the centering of the annular steel cylinder 20 and the positioning of the reinforcing plate 30 relative to the annular steel cylinder 20; on the other hand, the lateral pressure plate 206 will realize the centering of the annular steel plate 10, so that the annular steel plate 10 and the annular steel cylinder 20 are coaxially positioned. During the process of the pressing plate 211 pressing down, due to the inward movement of the limiting plate 207, the positions of the reinforcing plate 30 and the feeding trough 210 limited therebetween will be staggered, and the pressing plate 211 will press down on the top surfaces of the annular steel cylinder 20 and the reinforcing plate 30 to achieve positioning and clamping between the annular steel plate 10, the annular steel cylinder 20 and the reinforcing plate 30, and then the connecting parts between them can be welded.

[0044] Through the combination of the support frame and the positioning clamping mechanism, the present invention can realize the positioning and loading of the reinforcing plate 30 and the positioning and clamping between the annular steel plate 10, the annular steel cylinder 20 and the reinforcing plate 30 in steps during the process of driving the driving plate 201 to descend, thereby improving the welding positioning efficiency of the welded parts as a whole.

[0045] Although the present invention has been described in detail above by general description and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to the present invention. Therefore, these modifications or improvements made without departing from the spirit of the present invention all belong to the scope of protection claimed by the present invention.
