Description

Technical Field

[0001] The utility model belongs to the technical field of lead-acid battery production, and in particular relates to a lug oxide removal tool. Background Art

[0002] The structure of a lead-acid battery includes a group formed by alternately stacking positive and negative plates, the top surfaces of which are provided with positive and negative pole ears, respectively. All positive pole ears in the same pole group are connected in series using a positive pole bus, and all negative pole ears in the same pole group are connected in series using a negative pole bus. Adjacent pole groups are then connected in series by connecting the positive and negative buses.

[0003] Since the end of the pole ear needs to be cast-welded to connect the busbar, at least the position where the pole ear is connected to the busbar needs to be kept clean and free of oxides, otherwise it will affect the connection between the pole ear and the busbar.

[0004] In the prior art, it is necessary to brush the tabs of the pole plates before cast welding to remove oxides on the surface of the tabs.

[0005] For example, the invention application with publication number CN101098001A discloses a brush ear device, including: a frame, a motor and a mounting plate are arranged on the frame, a rotating shaft is arranged on the mounting plate through a bearing and a bearing seat, a roller-shaped brush is arranged on the rotating shaft, the output shaft of the motor is connected to the rotating shaft through a transmission device, one side of the table panel is movably arranged on the mounting plate through a guide rail pair, and the other side of the table panel is abutted against the mounting plate, so that the table panel can move straight back and forth along the guide rail pair, and the table panel is provided with a washing hole matching the roller-shaped brush and a positioning device matching the washing hole.

[0006] However, if the plate after the ear is brushed is not cast-welded in time, it may be oxidized again. Therefore, before the plate is cast-welded, the ear of the individual plate is checked for oxides, and the oxides on the surface of the ear are generally removed manually. At present, there is a lack of a good device for manually removing the oxides on the surface of the ear. Utility Model Content

[0024] like Figures 1 to 3 As shown, a tab oxide removal tool is used to remove oxide 12 at the end of the tab 11 on the top surface of the plate 1.

[0025] The lug oxide removal tool of the present application comprises a long-nosed pliers, which comprises a pair of pliers handles which are crossed with each other and hinged at the intersection by a fixed rotating shaft 2, and the pliers handles comprise a handle end 3 for operation and a pliers head end 4 for removing oxides 12 on the surface of the lug 11.

[0026] A pair of mutually matching clamping blocks 6 are respectively provided at the ends of the two clamp head ends 4, and a receiving cavity 61 for accommodating the cast welding area of ​​the end of the pole ear 11 and an avoidance cavity 62 for avoiding the part of the pole ear 11 that does not extend into the receiving cavity 61 are provided on the clamping surfaces of the two clamping blocks 6. Scrapers 63 for resisting against the surface of one side of the pole ear 11 are respectively provided in the avoidance cavity 62 near the receiving cavity 61, and the blade range of the scraper 63 is not less than the width of the pole ear 11.

[0027] One of the pliers head ends 4 is divided into two sections, and the clamp block 6 of the pliers head end 4 is located on one of the sections. The two sections are hinged by a rotating shaft 5, and the axial direction of the rotating shaft 5 is parallel to the axial direction of the fixed rotating shaft 2. By dividing one of the pliers head ends 4 into two hinged sections, the two clamp blocks 6 can keep the front and rear ends of the clamping surfaces moving synchronously when opening (i.e., in the process of moving away from each other), and the spacing changes at the same speed at the front and rear ends. Otherwise, if the two pliers head ends with only one section are opened, the spacing at the end close to the fixed rotating shaft 2 changes slowly, while the spacing at the end away from the fixed rotating shaft 2 changes quickly.

[0028] The two clamping blocks 6 are provided with a positioning step 64 on the clamping surface near one end of the clamp handle. The positioning step 64 can be used for positioning between the two clamping blocks 6 during use.

[0029] The two clamping blocks 6 are provided with bolts 65 passing through the two clamping blocks 6 in the area where the positioning steps 64 are located. One end of the bolt 65 extends out of the clamping block 6 and is matched with a nut 66. A reset spring 67 is sleeved in the area between the nut 66 and the clamping block 6 on the bolt 65. The reset spring 67 is located on the side where the clamp head end 4 divided into two sections is located. The setting of the bolt 65 further limits the movement between the two clamping blocks 6. In addition, the reset spring 67 can provide a force for the clamping blocks 6 to keep close to each other.

[0030] The clamp block 6 is provided with a mounting groove 68 for mounting the scraper 63. The mounting groove 68 opens on the clamping surface of the clamp block 6. The bottom surface of the mounting groove 68 has a threaded hole 69 that opens to the side of the clamp block 6 away from the clamping surface. The threaded hole 69 is provided with an adjustment stud 610 for abutting against the back side of the scraper 63. By rotating the adjustment stud 610 with a thread, the depth of the adjustment stud 610 in the threaded hole 69 can be adjusted, so that the position of the scraper 63 can be adjusted.

[0031] The end of the scraper 63 where the blade is located has an inclined surface 611 that tilts from the side close to the avoidance cavity 62 to the side close to the accommodating cavity 61 , and the inclined surface 611 is located on one side of the clamping surface to form a blade.

[0032] A limiting hole is provided on the side wall of the mounting groove 68 close to the avoidance cavity 62 , in which a push rod 612 whose end abuts against the upper inclined surface of the scraper is provided, and a support spring 613 for supporting the push rod 612 is provided on the inner side of the push rod 612 in the limiting hole.

[0033] In order to facilitate the extension of the pole ear 11 between the two clamping blocks 6 , the clamping block 6 is provided with a chamfer 614 at the mouth of the avoidance cavity 62 .

[0034] When the utility model is used, the pole ear oxide removal tool is used to control the movement of the pliers head end by operating the handle end, the two clamping blocks 6 clamp the pole ear 11, and then the long-nosed pliers are pulled away from the pole ear 11. In the process of the long-nosed pliers moving away from the pole ear 11, the two scrapers 63 scrape off the oxides 12 attached to both sides of the pole ear 11.
