Description

Technical Field

[0001] The present invention relates to the technical field of electric power equipment, in particular to a silver alloy welding wire micro-tension take-up device. Background Art

[0002] Silver alloy solders offer excellent processing properties, a low melting point, good wettability and gap-filling properties, and exceptional strength, plasticity, conductivity, and corrosion resistance. They can be used to braze nearly all ferrous and non-ferrous metals, with the exception of aluminum, magnesium, and other low-melting-point metals, resulting in widespread application. In particular, silver alloy solders are the most widely used and preferred solder in the refrigeration industry, where they are used in relatively large quantities. However, silver is a precious metal, and in recent years, to conserve silver, research institutes producing and manufacturing silver alloy solders have generally adopted multi-element alloying to reduce the silver content without raising the solder's melting point.

DETAILED DESCRIPTION

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] See also Figures 1-8 The present invention provides two technical solutions, specifically including the following embodiments:

[0033] Example 1: Reference Figure 1 , a silver alloy welding wire micro-tension take-up device, comprising a bottom base plate 1, side plates 2 are provided on both sides of the top surface of the bottom base plate 1, pins 3 for connecting to the bottom base plate 1 are inserted on both sides of the inner side plates 2, the side plates 2 and the bottom base plate 1 are detachable, and when disassembling, the pins 3 are pulled upward, and then the side plates 2 on both sides are removed in turn. When installing, the same is true. Rectangular grooves adapted to the bottom base plate 1 are provided on both sides of the bottom of the side plates 2 for clamping. In this way, the convenience of use of the equipment can be improved, while reducing the space occupied during transportation;

[0034] For further reference, Figures 1-8, the top surface of the side plate 2 is fixed with a positioning frame 10, and the two positioning frames 10 are rotatably connected to the transmission end shaft 11, and a transmission shaft 4 is provided between the two transmission end shafts 11, and a transmission end head 401 is fixed at both ends of the transmission shaft 4. A take-up reel 5 is slidably sleeved on the outside of the transmission shaft 4. The transmission end shaft 11 is an open type and a transmission slot 1101 is opened inside. The transmission end shaft 11 is located on one side of the open type and is slidably connected with a locking plate frame 12. The locking plate frame 12 is used to lock the transmission end head 401 inserted into the transmission slot 1101. When the welding wire is wound or unwound, as the transmission end shaft 11 rotates, the transmission end head 401 can be driven to rotate. The driving shaft 4 rotates so that the take-up reel 5 can rotate with the transmission shaft 4 to perform winding or unwinding operations. An arc-shaped limit groove 1103 is provided inside the transmission end shaft 11, and the locking plate frame 12 slides inside the corresponding arc-shaped limit groove 1103. A plurality of return springs 1202 are fixed between the end of the locking plate frame 12 and the inner wall of the arc-shaped limit groove 1103. The locking plate frame 12 can prevent the transmission end head 401 from falling off from the corresponding transmission notch 1101 during the rotation of the transmission end shaft 11. The shape formed between the locking plate frame 12 and the inner wall of the inner transmission notch 1101 is adapted to the transmission end head 401, and both are regular hexagons to ensure the transmission effect.

[0035] For further reference, Figure 3-Figure 5 , a limited slot 1102 is provided inside the transmission end shaft 11, and a slider 1201 is fixedly installed on the outside of the locking plate frame 12. The slider 1201 is slidably installed inside the limited slot 1102. When the take-up drum 5 is disassembled, the slider 1201 can be pushed outward so that the slider 1201 slides along the limited slot 1102 and drives the locking plate frame 12 to retract, so that the open side of the transmission end shaft 11 is opened, and the take-up drum 5 can be set up by hoisting or manually lifting, so that the transmission end head 401 at the end of the transmission shaft 4 is disengaged from the transmission slot 1101, and the disassembly operation can be completed;

[0036] Specifically, refer to Figure 1 A servo motor 6 is fixedly installed inside the side plate 2, and a transmission belt 601 is rotatably connected between the output end of the servo motor 6 and the end of the corresponding transmission end shaft 11, which is used to drive the transmission end shaft 11 to rotate inside the corresponding positioning frame 10. The servo motor 6 is an existing forward and reverse motor and will not be described in detail here. Through the operation of the servo motor 6, the corresponding transmission end shaft 11 can be driven to rotate through the cooperation of the transmission belt 601, so that the transmission shaft 4 and the take-up reel 5 can run with the transmission end shaft 11 to wind or unwind the welding wire. The transmission belt 601 is an existing friction track for transmission operation; specifically, the transmission end shaft 11 always remains coaxial with the locking plate frame 12 and the positioning frame 10;

[0037] Furthermore, the bottom base plate 1 and the side plates 2 of the bottom frame are made of alloy steel material, which has the advantages of high strength, high toughness, wear resistance and corrosion resistance compared to the traditional PE material injection molding frame;

[0038] Furthermore, the bottom frame is a pull rod type, that is, a detachable pull rod is provided on the outside of the side plate 2, and a plurality of rollers are provided at the bottom of the bottom base plate 1. The detachable pull rod and the rollers are both existing devices and are not shown in the figure;

[0039] Furthermore, a manual drive slot is provided on the outside of the transmission end 401, and the internal shape of the manual drive slot is a regular hexagon. During operation, the winding or unwinding operation can be achieved by inserting the rocker into the manual drive slot and manually rotating it. The rocker is Z-shaped and the end is set to a regular hexagon that matches the manual drive slot, which is not shown in the figure.

[0040] Example 2: Based on Example 1, on the basis of Example 1, refer to Figure 4-Figure 7 When the locking plate frame 12 is in the state of being pressed down, the locking plate frame 12 is automatically reset by the return spring 1202 at the end, thereby completing the locking operation of the transmission end 401.

[0041] When the transmission pressure plate 13 slides downward, the sliding rod 1301 can slide inside the corresponding limiting groove 1402 to ensure the limiting effect. When the transmission end head 401 enters the transmission notch 1101 and completes locking, the transmission pressure plate 13 and the sliding rod 1301 can be reset by the cooperation of the spring body 1302.

[0042] Specifically, the outer side of the side limit frame 14 is provided with a plurality of positioning bolts 1401, and is fixedly mounted on the inner side of the positioning frame 10 through the cooperation of the positioning bolts 1401;

[0043] Furthermore, arc-shaped auxiliary frames 15 are fixedly installed on both sides of the interior of the positioning frame 10. The arc-shaped auxiliary frames 15 can be used to limit the position of the transmission shaft 4 and the transmission end head 401 during installation. Through the arrangement of the arc-shaped auxiliary frames 15, the transmission end head 401 can be ensured to be located directly above the transmission pressure plate 13 during the downward movement, ensuring that the transmission end head 401 can be inserted into the transmission slot 1101 when pressed down, thereby ensuring the locking effect;

[0044] For further reference, Figure 2 、 Figure 8 A support plate 8 is provided between the two side plates 2, and a concave frame 801 is slidably connected inside the support plate 8. The installation position of the concave frame 801 is located directly below the take-up drum 5, and is used to limit the welding wire inside the take-up drum 5. The outer side of the concave frame 801 is rotatably sleeved with a limiting roller 802. The support plate 8 and the concave frame 801 are used to limit the welding wire inside the take-up drum 5. Both ends of the concave frame 801 pass through the support plate 8 and are slidably connected thereto. Both ends of the concave frame 801 passing through the support plate 8 are sleeved with support springs 803. When assembling the take-up drum 5, the support plate 8 can be first installed to the When the wire take-up drum 5 is installed between the two side plates 2, as the welding wire inside the wire take-up drum 5 contacts the concave frame 801, the concave frame 801 can be driven to slide down, and the supporting spring 803 can be stretched, so that the concave frame 801 can apply a limiting force upward to prevent the welding wire inside the wire take-up drum 5 from scattering. When the welding wire inside the wire take-up drum 5 is wound or unwound, the limiting roller 802 that is rotatably sleeved on the outer side of the concave frame 801 can always contact the welding wire inside the wire take-up drum 5, and maintain the limiting effect through the cooperation of the concave frame 801, thereby preventing the welding wire from scattering during the winding or unwinding process, further improving the use effect of the equipment.

[0045] Specifically, the inner sides of the two side panels 2 are fixedly mounted with concave limit frames 7, and both ends of the support plate 8 are slidably inserted into the interior of the concave limit frames 7, which can facilitate the disassembly of the support plate 8;

[0046] Bottom support frames 9 are fixedly installed on both sides of the top surface of the support plate 8. The two bottom support frames 9 are respectively located on both sides of the bottom of the take-up drum 5, and the top surface of the bottom support frame 9 is rotatably connected with multiple spherical bodies 901. As the two sides of the take-up drum 5 contact the top surface of the bottom support frame 9, the bottom support frame 9 can provide supporting force, reduce the load-bearing capacity of both ends of the transmission shaft 4, and improve the operating stability of the equipment.
