Detailed Implementation

[0024] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[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 and clamping mechanism.

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

[0027] The positioning and clamping mechanism includes a drive plate 201 that is driven to move up and down by a power mechanism. The support frame also includes a mounting plate (not shown in the figure) installed above the base 101. The power mechanism is a cylinder 205 installed on the mounting plate, and the drive plate 201 is connected to the bottom of the cylinder 205.

[0028] The drive plate 201 is connected below a guide plate 204 that can be locked onto the base 101 via a return spring 202. Specifically:

[0029] The guide plate 204 is provided with a guide rod 213 on its surface, and the drive plate 201 is provided with a guide groove 214 that can slide vertically through the guide rod 213. The reset spring 202 is fitted on the outside of the guide rod 213.

[0030] The base 101 is provided with a positioning groove 103, the bottom of the guide plate 204 can be locked in 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] A lateral pressure plate 206 is connected to the outer side of the guide plate 204 via a compression spring 203. In this embodiment of the invention, a groove 215 is formed around the guide plate 204, and a sliding sleeve 216 is provided on the inner side of the lateral pressure plate 206, which can slide along the corresponding side of the groove 215. The compression spring 203 is disposed inside the groove 215 and the sliding sleeve 216.

[0032] A limiting plate 207 with an outward opening forming a limiting groove 208 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. The width of the limiting plate 207 is smaller than the width of the reinforcing plate 30, which can prevent the limiting plate 207 from obstructing the welding part.

[0034] The drive plate 201 is equipped with a drive component, which has a feeding groove 210 for vertically feeding the reinforcing plate 30. When the drive component acts on the inner wall of the lateral pressure plate 206, the lateral pressure plate 206 can move outward. Specifically:

[0035] The driving component is a wedge-shaped connecting plate 209 that extends upward from the inside to the outside and is mounted on the driving plate 201. The feeding groove 210 is opened on the wedge-shaped connecting plate 209, and the feeding groove 210 can be directly aligned with the limiting groove 208 on the corresponding side below. The inner side of the top of the lateral pressure plate 206 is provided with a wedge-shaped surface 212 that cooperates with the wedge-shaped connecting plate 209.

[0036] A pressure plate 211 is also connected to the drive plate 201, and the pressure plate 211 can press on the top surface of the annular steel cylinder 20 and the reinforcing plate 30.

[0037] The working principle of the device of this invention is as follows:

[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 start cylinder 205 drives the plate 201 down, and the guide plate 204 connected to the bottom of the drive plate 201 by the reset spring 202 sinks into the positioning groove 103 on the base 101.

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

[0041] As the drive plate 201 descends further, the wedge-shaped connecting plate 209 moves into the lateral pressure plate 206 where the wedge-shaped surface 212 is located, and the reinforcing plate 30 is placed in the limiting groove 208 formed by the limiting plate 207 outside the lateral pressure plate 206. The reinforcing plate 30 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. 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 feeding of the reinforcing plate 30.

[0043] Finally, the drive plate 201 is further pressed down, and the wedge-shaped connecting plate 209 connected to the drive plate 201 will squeeze the wedge-shaped surface 212, causing the lateral pressure plate 206 to move along the guide plate 204 towards the inner wall of the annular steel cylinder 20. On the one hand, it can drive the reinforcing plates 30 between each limiting groove 208 to be supported in the inner wall of the annular steel cylinder 20, completing the centering positioning of the annular steel cylinder 20 and the positioning of the reinforcing plates 30 relative to the annular steel cylinder 20; on the other hand, the lateral pressure plate 206 will realize the centering positioning of the annular steel plate 10, so that the annular steel plate 10 and the annular steel cylinder 20 are coaxially positioned. During the pressing process of the pressure plate 211, due to the inward movement of the limiting plate 207, the positions of the reinforcing plate 30 and the feeding trough 210 will be misaligned, and the pressure plate 211 will press down on the top surface 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. After that, the connecting parts between them can be welded.

[0044] By combining the support frame and the positioning and clamping mechanism, this invention can achieve the positioning and feeding 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 stages during the descent of the drive plate 201, thereby improving the overall welding positioning efficiency of the welded parts.

[0045] Although the present invention has been described in detail above with general descriptions and specific embodiments, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
