Description

Technical Field

[0001] The present application relates to the field of tapered pipe welding, and in particular to a tapered sheet metal welding positioning tool. Background Art

[0002] With the continuous development of industry, welding technology has found widespread application in mechanical manufacturing. In lighting equipment manufacturing, tapered tubes made from sheet metal are not only used as decorative tops for light poles, but also as protective covers for their exteriors. During production, these tapered sheet metal parts are typically cut into fan-shaped flat sheets, which are then pressed into a tapered shape using a forming mold. The sheet metal joints are then manually aligned and welded together to form the tapered tube structure. However, manual alignment of the sheet metal joints can easily lead to misalignment of the upper and lower end faces of the tapered sheet metal and uneven weld widths. Utility Model Content

[0003] In order to solve the above-mentioned deficiencies of the prior art, the present application provides a conical sheet metal welding positioning tool, which can align the upper and lower end surfaces of the conical sheet metal while ensuring that the width of the welds at all locations is consistent.

[0004] In order to achieve the above purpose, the utility model adopts the following technologies:

[0005] A conical sheet metal welding positioning tool, comprising:

[0006] A fixed platform, the exterior of which is a conical structure;

[0007] The adjustment assembly includes a positioning ring, the inner ring of which is a circular structure. The diameter of the inner ring of the positioning ring is larger than the outer diameter of the fixed cone top and smaller than the outer diameter of the fixed cone bottom. A pressure plate is provided above the positioning ring in parallel, and the distance between the positioning ring and the pressure plate is adjustable.

[0008] The adjusting component is arranged at one end of the cone top of the fixing platform, the positioning ring faces the fixing platform, and the positioning ring is coaxial with the fixing platform.

[0009] The beneficial effects of the utility model are as follows: when welding a conical sheet metal, the conical sheet metal positioning tool can realize the positioning of the conical sheet metal by the coordinated action of the adjustment component and the fixing platform, so that the upper and lower end surfaces of the conical sheet metal are flush, and at the same time the joints of the conical sheet metal are neatly fitted, thereby ensuring that the width of the weld is consistent at all locations; the provision of the groove can prevent the molten solder from connecting the conical sheet metal and the fixing platform as a whole during welding, and facilitates the removal of the welded conical sheet metal; the limiting part in the groove can make the joint of the conical sheet metal fall within the range of the groove, thereby improving the welding quality and automation level of the conical sheet metal in many aspects.

[0014] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the implementation methods of the present invention are described in detail below with reference to the accompanying drawings. However, the embodiments described in the present invention are only part of the embodiments of the present invention, rather than all the embodiments.

[0015] The embodiment of the present application provides a tapered sheet metal positioning tool, such as Figure 1 As shown, it includes a fixed platform 1 and an adjustment assembly. The fixed platform 1 has a conical exterior. The adjustment assembly includes a positioning ring 2, whose inner and outer rings are both circular. The inner diameter of the positioning ring 2 is larger than the outer diameter of the top of the cone of the fixed platform 1, but smaller than the outer diameter of the bottom of the cone of the fixed platform 1. A pressure plate 3 is installed above and parallel to the positioning ring 2, and the distance between the positioning ring 2 and the pressure plate 3 is adjustable. The adjustment assembly is located at one end of the top of the cone of the fixed platform, with the positioning ring 2 facing the fixed platform 1 and coaxial with the fixed platform 1.

[0016] When in use, the conical sheet metal is placed on the fixed platform 1, and the joint of the conical sheet metal is facing any side of the fixed platform 1; then, the adjusting component is moved toward the fixed platform 1 along the axis, and the positioning ring 2 will gradually be mounted on the outer wall of the conical sheet metal until the lower edge of the inner ring of the positioning ring 2 contacts the outer wall of the conical sheet metal; and the positioning ring 2 is used to press the conical sheet metal inward, so that the joint of the conical sheet metal is aligned; continue to move the adjusting component, because there is a limiting effect of the fixed platform 1, the positioning ring 2 will not be able to move further, and then, the pressing plate 3 will move toward the conical sheet metal relative to the positioning ring 2, and use the pressing plate 3 to press the upper end surface of the conical sheet metal, so that the upper and lower end surfaces of the conical sheet metal are aligned; when welding, you can first spot weld and fix the two ends of the conical sheet metal joint, then take out the adjusting component, and then fully weld the conical sheet metal joint. Through the positioning tooling, the welding of the conical sheet metal can achieve the technical effect of point-to-point alignment and line-to-line alignment, thereby improving the quality of conical sheet metal welding.

[0017] Preferably, Figure 1 and Figure 2As shown, in order to prevent the molten solder from connecting the tapered sheet metal and the fixing platform 1 as a whole during welding, a groove 11 is provided on the peripheral side of the fixing platform 1 along the busbar direction. When positioning, the joint of the tapered sheet metal is located within the groove.

[0018] Specifically, the tapered sheet metal joint can be manually limited to the groove range, or it can be achieved by setting a limiter 12. Figure 1-Figure 3 As shown, a stopper 12 is provided within the groove 11. Both sides of its cross-section along the length of the groove 11 are inclined surfaces 121. The stopper 2 is arranged to move in a direction perpendicular to the bottom surface of the groove 11. When positioning the tapered sheet metal, the stopper 12 is passed through the joint of the tapered sheet metal. When the positioning ring 2 pulls the tapered sheet metal toward the center, the two side walls at the joint of the tapered sheet metal squeeze the inclined surfaces 121, causing the stopper 22 to move toward the bottom of the groove 11, thereby squeezing the stopper 12 out of the joint of the tapered sheet metal to avoid affecting the alignment of the joint.

[0019] More specifically, Figure 3 As shown, a movable rod 122 is provided at one end of the stopper 12 facing the bottom of the groove 11, which is sheathed with a first spring 14. The movable rod 122 passes through the bottom of the groove 11, and a countersunk hole is formed at the bottom of the groove 11 to accommodate the first spring 14. When the stopper 12 is squeezed out of the joint of the tapered sheet metal, the first spring 12 is compressed, and the movable rod 12 retracts toward the bottom of the countersunk hole 13.

[0020] Preferably, in order to improve the connection stability between the limiting member 12 and the groove 11 , two sides of the limiting member 12 are in sliding contact with two inner walls of the groove 11 .

[0021] Preferably, Figure 1 and Figure 4 As shown, to achieve adjustable distance between the positioning ring 2 and the pressure plate 3, two fixing rods 21 are vertically provided on the top surface of the positioning ring 2. The fixing rods 21 pass vertically through the pressure plate 3. Second springs 22 are inserted through the fixing rods 21. The second springs 22 are located between the positioning ring 2 and the pressure plate 3. When the pressure plate 3 moves toward the tapered sheet metal relative to the positioning ring 2, the second springs 22 will be compressed. Specifically, the movement of the pressure plate 3 can be achieved manually or by setting up a related drive mechanism.

[0022] If it is achieved by setting up relevant driving mechanisms, such as Figure 1 and Figure 4 As shown, a push rod 4 is vertically fixed above the pressing plate 3 , and the other end of the push rod 4 is connected to the telescopic shaft of a linear motor 5 , which is used to control the adjustment component to move along the axis direction of the fixed platform 1 .

[0023] Further preferably, in order to achieve higher precision alignment of the tapered sheet metal joints, the diameter of the positioning ring 2 is equal to the sum of the diameter of the middle section of the fixing table 1 and twice the wall thickness of the tapered sheet metal, so that the positioning ring 2 is at the middle height of the fixing table 1 when the tapered sheet metal is pressed, thereby making the tapered sheet metal joints fit more neatly.

[0024] During application, the conical sheet metal is placed on the fixed platform 1, with the joint of the conical sheet metal facing any side of the fixed platform 1, and then the limiter 12 is used to make it pass through the joint of the conical sheet metal; then, the linear motor 5 is turned on to control the adjustment component to move downward along the axis of the fixed platform 1, and the positioning ring 2 will gradually be sleeved on the middle section of the outer wall of the conical sheet metal until the lower edge of the inner ring of the positioning ring contacts the middle section of the outer wall of the conical sheet metal, and the positioning ring 2 is used to press the conical sheet metal inward. In this process, the two side walls at the joint of the conical sheet metal will squeeze the limiter 22 to the vertical direction through the extrusion slope 121. The linear motor 5 continues to control the adjustment assembly to move downward. Due to the limiting effect of the fixed platform 1, the positioning ring 2 will not be able to move further, and the pressure plate 3 will move toward the conical sheet metal relative to the positioning ring 2. At this time, the second spring 22 mounted on the fixed rod 21 is in a compressed state until the pressure plate 3 is pressed against the upper end face of the conical sheet metal, thereby aligning the upper and lower end faces of the conical sheet metal. When welding, you can first spot weld the two ends of the conical sheet metal joint, then remove the adjustment assembly, and then fully weld the conical sheet metal joint.

[0025] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Obviously, those skilled in the art can make various changes and modifications to the present application without departing from the spirit and scope of the present application.
