Description

Technical Field

[0001] This utility model relates to the field of welding wire production and packaging technology, specifically a clamp for making metal welding wire spools. Background Technology

[0002] The structure of the finished welding wire packaging metal welding wire spool with a center hole is formed by bending and welding 4mm steel wire to form a skeleton spool structure. First, the outer ring, inner ring, and spokes need to be welded into a side ring assembly. Then, two side ring assemblies and 12 transverse ribs are welded together to form a complete metal welding wire spool. During the welding process of the side ring assembly and transverse ribs, the two side ring assemblies need to be concentric and the spacing needs to be precisely controlled. The transverse ribs need to be evenly distributed at the spokes. Therefore, when the two side ring assemblies are installed into the fixture, center positioning, spacing positioning of the two side ring assemblies, and spoke angle positioning are required to complete the clamping and positioning of the side ring assembly and transverse ribs. The transverse ribs are divided into 4 inner transverse ribs and 8 outer transverse ribs, with a total of 24 welding points. While completing the clamping and positioning of the side ring assembly and transverse ribs, space for the electrode of the welding mechanism to move must be left. Currently, a shaft is typically used to center the side ring assembly by passing through the inner ring of the two side ring assemblies. The spoke angle is positioned by positioning the side plate near the edge. During the welding process, it is necessary to ensure that the side ring assembly does not move and the distance between the two side ring assemblies cannot be changed. This requires manual operation. When there are many welding points, manual operation is complicated and difficult. Utility Model Content

[0024] The present invention will be described in detail below with reference to the embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of the present invention can be combined with each other.

[0025] Please see Figure 1-6 This utility model provides a technical solution: a clamp for making metal welding wire spools, characterized in that: it includes a tray 2, eight support plates A3, multiple support plates B5, multiple guide rods 4, and four support plates C7 arranged on the tray 2;

[0026] Each of the aforementioned backplates A3 is provided with a groove A for the vertical tray 2. A lever 33 is installed in the groove A via a pin 32. The lever 33 can rotate around the pin 32. A spring 31 is provided at one end of the groove A near the tray 2. A protrusion is provided on one side of the backplate A3 near the center of the tray 2. The protrusion is provided with a groove B for the vertical tray 2. The groove B is located at the position of the corresponding preset horizontal rib A14. The two ends of each horizontal rib A14 are welded to the spokes 13 of the corresponding two side ring assemblies 1. Each horizontal rib A14 is pushed into the corresponding groove B by a feeding device to clamp and position each horizontal rib A14.

[0027] Each of the back plates B5 has a spring plunger 6 on the side near the groove B at the end away from the tray 2. The spring plunger 6 cooperates with the toggle block 33 to precisely position the spokes 13 of the second side ring assembly 1.

[0028] A gap is provided between the opposite sides of the back plate A and the corresponding back plate B. The width of the gap is greater than the cross-sectional diameter of the spoke and less than 1.13 times the cross-sectional diameter of the spoke, for positioning the spoke 13 of the first side ring assembly 1.

[0029] Each of the backing plates C7 is provided with a groove C of the vertical tray 2. The groove C is set at the position of the corresponding preset horizontal rib B15. The two ends of each horizontal rib B15 are respectively welded to the inner ring 11 of the two side ring assemblies 1. Each horizontal rib B15 is pushed into the corresponding groove C by the feeding device to clamp and position each horizontal rib B15.

[0030] The distance from the surface of each guide rod 4 near the center of the tray 2 to the center of the tray 2 is equal to the radius of the inner ring 11 of the side ring assembly 1. Multiple guide rods 4 work together to accurately position the inner ring 11 of the two side ring assemblies 1.

[0031] The number of the back plate B5 and the guide rod 4 are both even numbers less than 10. The angle between the line connecting two adjacent back plates A3 and the center of the tray 2 is 45°. The angle between the line connecting two adjacent guide rods 4 and the center of the tray 2 is a multiple of 45°. The angle between the line connecting two adjacent back plates C7 and the center of the tray 2 is 90°. The angle between the adjacent spokes 13 of the side ring assembly 1 is 45°.

[0032] Preferably, each of the backplates A3, B5, C7, and guide rods 4 has a chamfer at the end away from the tray 2 to facilitate the arrangement of the two side ring assemblies 1.

[0033] Preferably, each of the grooves A, B, and C has a chamfer at the end away from the tray 2 to facilitate the arrangement of the corresponding cross ribs A14 and B15.

[0034] Preferably, the number of the backing plate B5 and the guide rod 4 are both 4, so as to better clamp and position the side ring assembly 1 and the transverse rib A14.

[0035] like Figure 5 In the initial state, the two side ring assemblies 1, the eight horizontal ribs A14 and the four horizontal ribs B15 have not yet been installed in this utility model. Under the action of the spring 31, the lower end of the lever 33 pops out and its upper end is fully embedded in the groove A.

[0036] During the installation of the first side ring assembly 1, the spokes 13 on the first side ring assembly 1 slide down along the gap between the opposite sides of the back plate A3 and the back plate C5. At the same time, this gap also restricts the movement of the first side ring assembly 1. In addition, the area enclosed by the four guide rods 4 restricts the movement of the inner ring 11 of the first side ring assembly 1, thus completing the guiding and positioning of the first side ring assembly 1.

[0037] like Figure 4 After the first side ring assembly 1 is fully installed, it is placed on the tray 2. The spokes 13 of the first side ring assembly 1 move the corresponding lever 33. The lever 33 compresses the corresponding spring 31. The lower end of the lever 33 is fully embedded in the groove A, and its upper end rotates and protrudes to expose a platform. At this time, the second side ring assembly 1 is installed. The three-dimensional spokes 13 of the second side ring assembly rest against the upper platform of the corresponding lever 33. The spring plunger 6 at the top of the backing plate B5 holds the corresponding spoke, and the second side ring assembly 1 is fixed, completing the guiding and positioning of the second side ring assembly 1 and realizing the spacing positioning of the first side ring assembly 1 and the second side ring assembly 1.

[0038] Eight horizontal ribs A14 are inserted into the groove B of the backing plate A3, and four horizontal ribs B15 are inserted into the groove C of the backing plate C7. All side ring assemblies 1 and horizontal ribs are clamped and positioned, leaving room for the electrodes of the welding mechanism to move, so that the next welding process can be carried out.

[0039] After welding is completed, the metal welding wire spool is unloaded. All spokes 13 and transverse ribs are dislodged from the back plate A3, guide rod 4, back plate B5, spring plunger 6 and back plate C7. Each lever 33 loses the obstruction of the corresponding spoke 13 and rotates outward under the action of the corresponding spring 31, restoring the initial state of this utility model.

[0040] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions and substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the protection scope of the present invention.
