Abstract
Description
Technical Field
[0001] This utility model belongs to the field of acid adding machine technology, and in particular relates to an acid tube clamping mechanism for a battery acid adding machine. Background Technology
[0002] In the manufacturing process of lead-acid batteries, the electrode group is first pressed into the battery case, then the case cover is covered and sealed with glue, and then acid is injected through the acid filling hole on the cover. When adding acid to the battery, an acid filling machine is required.
[0003] For example, Chinese utility model CN221900161U discloses an acid outlet clamping device. The latex tube of the acid adding machine is fixed neatly by a PVC positioning plate and then passes through the middle of a stainless steel fixing rod. A cylinder is used to clamp the latex tube to control the synchronicity of acid dispensing, thus solving the problem of asynchronous acid dispensing caused by the original separate control of acid dispensing.
[0004] However, in the existing technology, multiple pairs of latex tubes are clamped simultaneously by using a cylinder to drive a fixed tie rod. The fixed tie rod squeezes the latex tubes to one side, which not only increases the pulling force on the latex tubes, which can easily lead to damage, but also makes the clamping process longer, affecting the response speed of clamping and sealing the latex tubes, as well as the accuracy of acid injection. Utility Model Content
[0005] The purpose of this utility model is to provide an acid tube clamping mechanism for a battery acid filling machine. By synchronously driving the two clamping plates to move relative to each other through a telescopic device, the acid filling tube is clamped, which solves the problem that the existing clamping process has a long stroke, affecting the accuracy of acid filling.
[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to an acid tube clamping mechanism for a battery acid filling machine, comprising a positioning plate with a plurality of positioning holes evenly distributed along its length. Two clamping plates are slidably connected to the positioning plate, and the two clamping plates are symmetrically arranged relative to the positioning holes. A rack is fixedly connected to each clamping plate. End plates are fixedly connected to both ends of the positioning plate, and two rotating shafts are rotatably connected to each end plate. The two rotating shafts correspond one-to-one with the two clamping plates and are fixedly connected to a drive wheel that meshes with the rack. A telescopic device is fixedly connected to each end plate, used to drive the two rotating shafts to rotate synchronously, thereby clamping the acid filling tube by relative movement of the two clamping plates.
[0007] As a preferred technical solution of this utility model, the opposite sides of the two clamping plates are curved.
[0008] As a preferred embodiment of this utility model, the upper and lower edges of the positioning hole are both machined with rounded corners.
[0009] As a preferred embodiment of this utility model, the positioning hole is an elliptical hole structure.
[0010] As a preferred technical solution of this utility model, both ends of the rotating shafts are fixedly connected to strip plates. The end of the strip plate away from the rotating shaft is provided with a straight groove, which is set along the length direction of the strip plate. The telescopic end of the telescopic device is fixedly connected to a guide post, which is in clearance fit with the straight groove of the two strip plates. The telescopic device pushes and pulls the strip plates through the guide post to drive the rotating shaft to rotate.
[0011] As a preferred embodiment of this utility model, both ends of the rotating shaft are fixedly connected to strip plates, and both end plates are fixedly connected to telescopic devices.
[0012] This utility model has the following beneficial effects: This utility model has two clamping plates slidably connected to a positioning plate, and the two clamping plates are symmetrically arranged with respect to the positioning holes. The two rotating shafts are driven to rotate synchronously by a telescopic device. By moving the two clamping plates relative to each other, the acid filling tube is clamped, thereby effectively shortening the stroke of a single clamping plate and enabling the acid filling tube to be quickly clamped and sealed, which helps to improve the overall acid filling accuracy.

Detailed Implementation
[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0017] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
[0018] Please see Figure 1 and 2 As shown, this utility model is an acid tube clamping mechanism for a battery acid filling machine, including a positioning plate 1. The positioning plate 1 has a plurality of positioning holes 101 evenly distributed along its length. The upper and lower edges of the positioning holes 101 are machined with rounded corners to reduce wear between them and the acid filling tube.
[0019] like Figures 3-5 As shown, the positioning plate 1 is slidably connected to two clamping plates 2, and the two clamping plates 2 are symmetrically arranged relative to the positioning hole 101. Specifically, the clamping plates 2 are made of PVC board, and the clamping plates 2 can be slidably connected to the positioning plate 1 through a guide rail slider assembly. Alternatively, as shown in the attached figure, the lower surface of the positioning plate 1 has two to four grooves, such as T-grooves or dovetail grooves. The clamping plates 2 are fixed with screws to the sliders that cooperate with the grooves to achieve mutual sliding connection.
[0020] The clamping plate 2 is fixedly connected with a rack 201. There can be multiple racks 201, such as the three racks shown in the attached figure. The three racks 201 are arranged along the length direction of the clamping plate 2, and the length direction of the racks 201 is parallel to the sliding direction of the clamping plate 2.
[0021] like Figure 6As shown, both ends of the positioning plate 1 are welded or fixedly connected to end plates 102 by screws. The length or width of the end plates 102 can be flexibly adjusted according to the installation equipment, facilitating overall installation and fixation via the end plates 102. The two end plates 102 are rotatably connected to two rotating shafts 3 via bearings. The two rotating shafts 3 correspond one-to-one with the two clamping plates 2 and are fixedly connected to a drive wheel 301 that meshes with the rack 201.
[0022] The end plate 102 is fixedly connected to a telescopic device 4 via a mounting base. The telescopic device 4 is a cylinder or an electric push rod, etc., used to drive the two rotating shafts 3 to rotate and use the two clamping plates 2 to move relative to each other to clamp the acid tube.
[0023] Specifically, strip plates 302 are fixedly connected to the ends of both rotating shafts 3. If the ends of the rotating shafts 3 are processed into flat shaft structures or D-shaped shaft structures, connecting holes that match them are opened at the ends of the strip plates 302, and axial positioning is achieved by locking with pins, screws or nuts, so that the strip plates 302 and the rotating shafts 3 remain relatively fixed.
[0024] A straight groove 303 is formed at the end of the strip plate 302 away from the rotating shaft 3, and the straight groove 303 is arranged along the length direction of the strip plate 302. A guide post 401 is fixedly connected to the telescopic end of the telescopic device 4, and the guide post 401 is clearance-fitted with the straight grooves 303 of the two strip plates 302. Furthermore, strip plates 302 are fixedly connected to both ends of the rotating shaft 3, and telescopic devices 4 are fixedly connected to both end plates 102, so that the two telescopic devices 4 drive the two ends of the two rotating shafts 3 respectively, making the load on the rotating shaft 3 more balanced, thereby ensuring the stability of the drive.
[0025] like Figure 7 As shown, in use, the acid-adding tube passes through the positioning hole 101 and is positioned between the two clamping plates 2. When it is necessary to clamp the acid-adding tube, the telescopic end of the telescopic device 4 extends and pushes the strip plates 302 at the ends of the two rotating shafts 3 downward through the guide post 401, thereby driving the rotating shafts 3 to rotate. During the rotation of the rotating shafts 3, the drive wheel 301 drives the rack 201, thereby causing the two clamping plates 2 to move towards each other, that is, towards the direction of the acid-adding tube, and gradually clamp the acid-adding tube, thus blocking the clamping tube. When the telescopic device 4 pulls the strip plates 302 upward, it drives the rotating shaft 3 to reverse, causing the two clamping plates 2 to slide away from the acid-adding tube, that is, to release the acid-adding tube.
[0026] By synchronously driving the two clamping plates 2 to move synchronously to clamp the acid filling tube, the stroke of a single clamping plate 2 is effectively shortened, allowing the acid filling tube to be quickly clamped and sealed, which helps to improve the overall acid filling accuracy.
[0027] Furthermore, by pushing and pulling the strip plate 302 through the telescopic device 4, the rotating shaft 3 is driven to rotate, thereby driving the clamping plate 2. The length of the strip plate 302 can achieve a labor-saving effect. The same type of cylinder can make the clamping plate 2 obtain a greater clamping force. Moreover, the telescopic device 4 is installed on the end plate 102, which facilitates subsequent maintenance and inspection, as well as convenient replacement of cylinder failure, thus further improving the overall practicality.
[0028] Preferably, the opposing sides of the two clamping plates 2 are curved, which reduces the clamping area and ensures that multiple acid-adding tubes can be clamped and sealed simultaneously, guaranteeing overall reliability. Simultaneously, the curved structure also reduces damage to the acid-adding tubes during clamping.
[0029] In addition, the positioning hole 101 is an elliptical hole structure. The design of the positioning hole 101 as an elliptical hole structure allows the positioning hole 101 to better adapt to the deformation of the acid tube when it is clamped, thereby further reducing the additional pressure or pulling force on the acid tube, which helps to improve the overall service life of the acid tube.
