Description

Technical Field

[0001] This utility model relates to the field of battery acid extraction technology, and in particular to a tooling for cutting grooves at the opening of an acid extraction pipe. Background Technology

[0002] During the production of batteries, excess acidic liquid may overflow after pre-charging. Therefore, it is necessary to perform acid extraction on the batteries. Acid extraction is an important process that involves the treatment and preparation of the electrolyte (usually a sulfuric acid solution) to ensure that the batteries have appropriate electrochemical performance during charging and discharging.

[0003] During acid extraction, the acid extraction tube of the acid extraction device is inserted into the battery through the hole in the battery cover. The excess acid is then extracted using negative pressure. To ensure that the excess acid is completely extracted, a groove is made at the opening of the acid extraction tube. When the opening of the acid extraction tube reaches the bottom of the battery compartment, the acid can enter the acid extraction tube through the groove and then be discharged from the battery compartment.

[0004] When installing existing acid extraction pipes in a tank, tooling is required to secure the pipes, such as... Figure 5 As shown, the tooling is generally a column with a limiting hole inside, a groove at the top, and a damping rubber ring at the bottom. The inner diameter of the damping rubber ring is smaller than that of the acid extraction tube. Therefore, when the acid extraction tube passes through the damping rubber ring, the damping rubber ring will undergo a large deformation, thereby fixing the acid extraction tube. However, after long-term use, the inner diameter of the damping rubber ring will gradually increase, and the binding force on the acid extraction tube will decrease. Therefore, after long-term use, the damping rubber ring will no longer be able to stably fix the position of the acid extraction tube, causing the acid extraction tube to shift during the grooving operation, which increases the difficulty of the grooving operation. Utility Model Content

[0005] The main purpose of this utility model is to provide a tooling for cutting grooves at the opening of an acid extraction tube. The elastic positioning component can hold the acid extraction tube in the limiting hole, thereby fixing the position of the acid extraction tube and preventing it from moving downward in the limiting hole due to force during the grooving operation, thus enabling long-term use.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A tooling for grooving the opening of an acid extraction tube includes a column body with a limiting hole for accommodating the acid extraction tube. The limiting hole at the top of the column body has a slot, and the bottom of the column body has a positioning groove communicating with the limiting hole. A damping rubber ring is provided in the positioning groove, and an elastic positioning component is provided on one side of the column body. The elastic positioning component is used to hold the acid extraction tube in the limiting hole.

[0008] Furthermore, the elastic positioning component includes a first hole and a second hole formed on one side of the column. The first hole and the second hole are connected and form a stepped surface. A positioning rod is inserted into the second hole. One end of the positioning rod is inserted into the first hole. An elastic element is sleeved around the positioning rod located in the second hole. One end of the elastic element is connected to the stepped surface, and the other end is connected to the positioning rod through a positioning ring.

[0009] Furthermore, the length of the positioning rod is greater than the sum of the lengths of the first hole and the second hole, and the other end of the positioning rod is located outside the second hole.

[0010] Furthermore, the elastic element is a cylindrical spring.

[0011] Furthermore, the cross-section of the groove is V-shaped.

[0012] Furthermore, the positioning groove includes a straight cylindrical groove and an arched groove, the arched groove being located at the top of the straight cylindrical groove and the top of the arched groove being connected to the limiting hole.

[0013] Furthermore, the damping rubber ring is fixed inside the straight cylindrical groove, and the diameter of the through hole of the damping rubber ring is equal to the diameter of the acid extraction tube.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The elastic positioning component of this utility model can hold the acid extraction tube in the limiting hole, thereby fixing the position of the acid extraction tube and preventing it from moving downward in the limiting hole due to force during the grooving operation, so that this tooling can be used for a long time.

[0016] The positioning rod of this invention compresses the elastic element through the positioning ring, so that one end of the positioning rod can extend into the limiting hole, thereby blocking the acid extraction tube in the limiting hole and preventing the acid extraction tube from moving downward due to force during the grooving process.

[0017] The cross-section of the groove in this invention is U-shaped. Therefore, by moving a blade along the groove, a V-shaped groove can be cut from the opening of the acid extraction tube.

[0018] The through-hole diameter of the damping rubber ring of this invention is equal to the diameter of the acid extraction tube. Therefore, although the acid extraction tube will come into contact with the damping rubber ring when passing through it, it will not cause too much obstruction to the movement of the acid extraction tube, so that personnel can insert the acid extraction tube into the limiting hole.

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] like Figure 1-4 As shown, a tooling for grooving the opening of an acid extraction tube includes a column 1, a limiting hole 2 for accommodating the acid extraction tube on the column 1, a slot 3 at the top of the limiting hole 2, a positioning groove 4 communicating with the limiting hole 2 at the bottom of the column 1, a damping rubber ring 5 in the positioning groove 4, and an elastic positioning component 8 on one side of the column 1 for holding the acid extraction tube in the limiting hole 2.

[0027] In this embodiment, such as Figure 4 As shown, the operator inserts the acid extraction tube to be cut into the limiting hole 2 from the positioning groove 4 upwards, ensuring that the top opening of the acid extraction tube is flush with the top opening of the limiting hole 2. At this time, the damping rubber ring 5 will contact the acid extraction tube, thus initially positioning the position of the acid extraction tube. When the operator uses a blade to cut the acid extraction tube, the operator can further fix the acid extraction tube through the elastic positioning component 8 to prevent the acid extraction tube from moving downwards in the limiting hole 2 due to force during the cutting operation.

[0028] Specifically, such as Figure 2As shown, the elastic positioning component 8 includes a first hole 801 and a second hole 802 formed on one side of the column 1. The diameter of the second hole 802 is larger than the diameter of the first hole 801. The first hole 801 and the second hole 802 are connected and form a stepped surface 803. A positioning rod 804 is inserted into the second hole 802. One end of the positioning rod 804 is inserted into the first hole 801. An elastic element 805 is sleeved around the positioning rod 804 located in the second hole 802. One end of the elastic element 805 is connected to the stepped surface 803, and the other end is connected to the positioning rod 804 through a positioning ring 806. The positioning rod 804 is longer than the first hole 801. The length of the first hole 801 is equal to the combined length of the second hole 802. The other end of the positioning rod 804 is located outside the second hole 802. Under normal conditions, the elastic element 805 is not under force. At this time, the positioning rod 804 will not extend out of the first hole 801 and enter the limiting hole 2. However, when it is necessary to hold the acid extraction tube in place, the operator can manually press the positioning rod 804 located outside the second hole 802. At this time, the positioning rod 804 will compress the elastic element 805 through the positioning ring 806, so that one end of the positioning rod 804 can extend into the limiting hole 2, thereby holding the acid extraction tube in the limiting hole 2 and preventing the acid extraction tube from moving downward due to force during the grooving process.

[0029] Among them, the elastic element 805 is a cylindrical spring.

[0030] Among them, such as Figure 1 and Figure 3 As shown, the cross-section of the groove 3 is V-shaped. Therefore, by moving a blade along the groove 3, the operator can cut a V-shaped groove from the opening of the acid extraction tube.

[0031] Among them, such as Figure 1 As shown, the positioning groove 4 includes a straight cylindrical groove 402 and an arched groove 401. The arched groove 401 is located at the top of the straight cylindrical groove 402, and the top of the arched groove 401 is connected to the limiting hole 2. The damping rubber ring 5 is fixed inside the straight cylindrical groove 402. The diameter of the through hole 501 of the damping rubber ring 5 is equal to the diameter of the acid extraction tube. Therefore, although the acid extraction tube will come into contact with the acid extraction tube when passing through the damping rubber ring 5, it will not cause too much obstruction to the movement of the acid extraction tube, so that personnel can insert the acid extraction tube into the limiting hole 2.

[0032] The working principle is as follows: First, the operator inserts the acid extraction tube upward from the positioning groove 4 into the limiting hole 2, ensuring that the top opening of the acid extraction tube is flush with the top opening of the limiting hole 2. At this time, the damping rubber ring 5 will contact the acid extraction tube, thus initially positioning the acid extraction tube. Then, the operator can manually press the positioning rod 804 located outside the second hole 802. At this time, the positioning rod 804 will compress the elastic element 805 through the positioning ring 806, so that one end of the positioning rod 804 can extend into the limiting hole 2, thereby pressing against the acid extraction tube inside the limiting hole 2 and further fixing the acid extraction tube. Then, the operator uses a blade to move along the groove 3 to cut a V-shaped groove in the opening of the acid extraction tube, completing the grooving operation.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
