Description

Technical Field

[0001] The invention relates to the technical field of lead-acid batteries, and in particular to a lead-acid battery terminal shaping tool. Background Art

[0002] Lead-acid battery is a storage battery whose electrodes are mainly made of lead and its oxides, and whose electrolyte is sulfuric acid solution. When the lead-acid battery is in the discharge state, the main component of the positive electrode is lead dioxide, and the main component of the negative electrode is lead; when it is in the charging state, the main components of the positive and negative electrodes are both lead sulfate. When processing lead-acid batteries, the external dimensions of the terminals on the large cover must meet the national standard or enterprise standard.

[0003] The existing technology has the following shortcomings: since the terminals are mass-produced parts, and the molds may be worn or the employees' operation methods may not be standard during welding, the terminal dimensions may not meet the standards during the actual production process. Therefore, there is an urgent need for a lead-acid battery terminal shaping tool to trim the terminal shape to within the standard range to meet the requirements of national standards or enterprise standards. Summary of the invention

[0004] Aiming at the deficiencies in the prior art, the present invention provides a lead-acid battery terminal shaping tool.

[0005] The present invention solves the above-mentioned technical problems through the following technical means: a lead-acid battery terminal shaping tool, comprising a shell, a top cover connected to the top of the shell, an adjusting screw penetrating the inside of the top cover, the adjusting screw and the top cover being threadedly connected, a pressure plate and a linkage disk arranged at the top of the inner cavity of the shell, the pressure plate and the linkage disk are both connected to the bottom of the adjusting screw, and ejector pins distributed in a ring array are arranged at the bottom of the linkage disk, the adjusting screw can be rotated to drive the pressure plate, the linkage disk, and the ejector pin to move up and down, the top of the ejector pin is embedded in the linkage disk, the pressure plate restricts the ejector pin in the linkage disk, a cutting knife is embedded at the bottom of the inner cavity of the shell at the position corresponding to the ejector pin, the bottom of the ejector pin is penetrated in the cutting knife, and the up and down movement of the ejector pin drives the cutting knife to move synchronously along the horizontal direction.

[0006] Preferably, a fixing ring is provided at the bottom of the inner cavity of the shell, a limiting groove is provided on the inner surface of the fixing ring, the cutting blade is movably arranged in the limiting groove, a through hole is provided on the top of the cutting blade, and the ejector pin is inserted in the through hole on the top of the cutting blade.

[0007] Preferably, the through hole and the ejector pin are both arranged to be inclined inwardly, and the angle between the central axis of the through hole and the horizontal plane is matched with the angle between the central axis of the ejector pin and the horizontal plane. When the ejector pin moves upward, the cutting knife is driven by the ejector pin to expand outward synchronously, and when the ejector pin moves downward, the cutting knife is driven by the ejector pin to move inward synchronously.

[0008] Preferably, a bottom cover is provided at the bottom of the outer shell. The bottom of the cutting tool is horizontal and is in close contact with the bottom cover. The top and bottom of the cutting tool are in close contact with the fixing ring and the bottom cover respectively.

[0009] Preferably, placement openings are formed at corresponding positions on the top of the linkage disk corresponding to the positions of the ejector pins, and the ejector pins are respectively placed in the placement openings at corresponding positions.

[0010] Preferably, a compression nut is provided on the top of the top cover, and the compression nut is threadedly connected to the outside of the adjusting screw rod.

[0011] Advantages of the present invention:

[0012] In the present invention, by rotating the adjusting screw rod, the driving pressure plate, the linkage disk, and the ejector pins are synchronously moved up and down. When the ejector pins move up and down, the driving cutting tool is synchronously moved. In this way, the size of the cone formed by the rotation between the cutting edges of the cutting tool can be adjusted. When the ejector pins move upward and drive the cutting tool to expand outward synchronously through the ejector pins, the cone formed between the cutting edges of the cutting tool becomes larger. When the ejector pins move downward and drive the cutting tool to move inward synchronously through the ejector pins, the cone formed between the cutting edges of the cutting tool becomes smaller. Therefore, by adjusting the movement of the cutting tool through the adjusting screw rod, the size of the cone formed by the rotation between the cutting edges of the cutting tool can be adjusted. The size of the cone formed by the rotation between the cutting edges of the cutting tool is adjusted to match the standard range of the lead-acid battery terminals under the national standard or enterprise standard. After the shaping tooling is adjusted to the required size, it is placed on the terminal and made perpendicular to the horizontal plane of the large cover. At this time, manually rotate the shaping tooling 1 to 2 circles, and the shape of the terminal can be trimmed through the cutting tool, so that the shape of the trimmed terminal will meet the standard requirements.

Obviously, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts shall fall within the protection scope of the present invention.

[0021] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there may also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time.

[0022] Embodiment

[0023] Please refer to Figure 1 And Figure 6As shown in the figure, a lead-acid battery terminal shaping tooling in this embodiment includes a housing 1. A top cover 2 is connected to the top of the housing 1. An adjusting screw rod 7 is disposed through the interior of the top cover 2, and the adjusting screw rod 7 is threadedly connected to the top cover 2. At the top of the inner cavity of the housing 1, there is a pressing plate 6 and a linkage disk 8. Both the pressing plate 6 and the linkage disk 8 are connected to the bottom of the adjusting screw rod 7. At the bottom of the linkage disk 8, there are thimble 9s distributed in an annular array. Rotating the adjusting screw rod 7 can drive the pressing plate 6, the linkage disk 8, and the thimble 9s to move up and down. The top of the thimble 9 is embedded in the linkage disk 8, and the pressing plate 6 restricts the thimble 9 in the linkage disk 8. At the bottom of the inner cavity of the housing 1, there is a fixing ring 16. A limiting groove 15 is formed on the inner surface of the fixing ring 16. A cutting tool 10 is movably disposed in the limiting groove 15. A through hole is formed at the top of the cutting tool 10, and the thimble 9 is inserted into the through hole at the top of the cutting tool 10. The bottom of the thimble 9 passes through the cutting tool 10. Both the through hole and the thimble 9 are inclined inward, and the included angle between the central axis of the through hole and the horizontal plane matches the included angle between the central axis of the thimble 9 and the horizontal plane. When the thimble 9 moves upward, the thimble 9 drives the cutting tool 10 to expand outward synchronously. When the thimble 9 moves downward, the thimble 9 drives the cutting tool 10 to move closer inward synchronously. A bottom cover 3 is disposed at the bottom of the housing 1. The bottom of the cutting tool 10 is horizontal and is in contact with the bottom cover 3. The top and bottom of the cutting tool 10 are in contact with the fixing ring 16 and the bottom cover 3 respectively. At the connection between the linkage disk 8 and the adjusting screw rod 7, there are a first screw 11 and a flat washer 12. The linkage disk 8 is fixedly connected to the adjusting screw rod 7 through the first screw 11 and the flat washer 12. At the connections between the bottom cover 3 and the top cover 2 and the housing 1, there are third screws 14. At the connections between the top cover 2 and the housing 1, there are second screws 13. The top cover 2 is fixedly connected to the housing 1 through the second screws 13. At the connections between the bottom cover 3 and the housing 1, there are third screws 14. The bottom cover 3 is fixedly connected to the housing 1 through the third screws 14. At the connection between the adjusting nut 4 and the adjusting screw rod 7, there is a fourth screw 18. The adjusting nut 4 is fixedly connected to the adjusting screw rod 7 through the fourth screw 18. A through groove is formed at the bottom of the bottom cover 3, and the lead-acid battery terminal can enter the housing 1 through the through groove at the bottom of the bottom cover 3.

[0024] The included angle between the cutting edge of the cutting tool 10 and the horizontal direction is set to match the included angle between the tapered surface side of the lead-acid battery terminal under national or enterprise standards and the horizontal direction. Since the cutting edge of the cutting tool 10 is inclined, when the cutting edge of the cutting tool 10 rotates, a cone that gradually increases from top to bottom will be formed between them. The lead-acid battery terminal under national or enterprise standards is also a cone that gradually increases from top to bottom.

[0025] By rotating the adjusting nut 4 to rotate the adjusting screw 7, since the adjusting screw 7 is threadedly connected to the top cover 2, when the adjusting screw 7 rotates, it will drive the pressure plate 6, the linkage disk 8, and the thimble 9 to move up and down synchronously. Since both the through hole and the thimble 9 are inclined inwardly, the included angle between the central axis of the through hole and the horizontal plane matches the included angle between the central axis of the thimble 9 and the horizontal plane. Also, the top and bottom of the cutting tool 10 are respectively in contact with the fixed ring 16 and the bottom cover 3. Under the restricting action of the fixed ring 16 and the bottom cover 3, when the thimble 9 moves up and down, it will drive the cutting tool 10 to move synchronously. In this way, the size of the cone formed by the rotation of the cutting edges of the cutting tool 10 can be adjusted. When the thimble 9 moves upward and drives the cutting tool 10 to expand outward synchronously through the thimble 9, the cone formed between the cutting edges of the cutting tool 10 becomes larger. When the thimble 9 moves downward and drives the cutting tool 10 to move inward synchronously through the thimble 9, the cone formed between the cutting edges of the cutting tool 10 becomes smaller. Thus, by adjusting the movement of the cutting tool 10 through the adjusting screw 7, the size of the cone formed by the rotation of the cutting edges of the cutting tool 10 can be adjusted. The size of the cone formed by the rotation of the cutting edges of the cutting tool 10 is adjusted to match the standard range of lead-acid battery terminals under national or enterprise standards. After the shaping tooling is adjusted to the required size, it is placed on the terminal and made perpendicular to the horizontal plane of the large cover. At this time, manually rotate the shaping tooling 1 to 2 circles, and the outer shape of the terminal can be trimmed through the cutting tool 10, so that the outer shape of the trimmed terminal will meet the standard requirements.

[0026] Please refer to Figure 6 As shown, placement openings 19 are provided at the positions corresponding to the thimbles 9 on the top of the linkage disk 8, and the thimbles 9 are respectively placed in the placement openings 19 at the corresponding positions; the setting of the placement openings 19 facilitates providing a carrier for the placement of the thimbles 9. The thimbles 9 are restricted within the linkage disk 8 by the pressure plate 6, so that it is convenient for the pressure plate and the linkage disk 8 to move up and down to drive the thimbles 9 to move up and down.

[0027] Please refer to Figure 1 and Figure 2 As shown, a compression nut 5 is provided on the top of the top cover 2, and the compression nut 5 is threadedly connected to the outside of the adjusting screw 7; when the adjusting screw 7 adjusts the pressure plate 6, the thimble 9, and the linkage disk 8, due to the poor stability of the adjusting screw 7, the adjusting screw 7 may rotate itself, resulting in the movement of the cutting tool 10. Therefore, the compression nut 5 is installed on the adjusting screw 7. By means of the compression nut 5, positioning treatment can be carried out on the adjusted adjusting screw 7, effectively preventing the adjusting screw 7 from rotating, and further preventing the movement of the cutting tool 10 from causing the correction accuracy of the terminal to deteriorate.
