[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a modular clamping mechanism that can quickly switch, reduce the time spent changing lines, and has low maintenance costs.
[0006] This utility model achieves the above objectives through the following technical means:

Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature.

Example
[0031] Please see Figure 1 and Figure 2This application discloses a modular clamping mechanism, including a locking block 10 and two clamping blocks 20. The locking block 10 includes a mounting base 11 and a vertical plate 12 mounted on the mounting base 11. The mounting base 11 is provided with five fixing holes 111 for fixing the locking block 10 to the substrate, providing a basis for welding, clamping and positioning the battery box. The top surface of the locking block 10 is provided with two screw holes 13. Each clamping block 20 is provided with a racetrack-shaped hole 23. A fixing bolt passes through the racetrack-shaped hole 23 and is installed in the corresponding screw hole 13, thereby connecting the locking block 10 and the two clamping blocks 20 together. The clamping block 20 has a clamping part 21 at one end and a contour clamping part 22 at the other end. A clamping space is formed between the clamping part 21 and the contour clamping part 22, thereby restricting the object to be clamped, i.e., the battery box frame, between the clamping part and the contour clamping part, and positioning and clamping the object. Since the racetrack-shaped hole has a certain length, clamping operations of objects of different widths can be achieved by passing the fixing bolt through different positions in the racetrack-shaped hole. Since the object to be clamped can be positioned and clamped by only the fixing bolt and the clamping block, quick switching can be achieved, reducing line change time. At the same time, because there are fewer parts, the maintenance cost is also low.
[0032] Specifically, a clamping plate 121 is provided on the side of the upright plate 12 closest to the object being clamped, and a locking clamping block 122 is provided on the side of the upright plate 12 furthest from the object being clamped. The locking clamping block 122 is connected to the clamping plate 121 through a clamping positioning block 123. A through hole 124 is provided on the upright plate 12 in the horizontal direction, and the clamping positioning block 123 passes through the through hole 124. By providing a clamping plate on the side of the upright plate closest to the object being clamped, it is possible to effectively prevent the upright plate from damaging the object being clamped and affecting its appearance.
[0033] Example 2: In this example, there are two locking blocks 10, which are arranged opposite each other, forming a clamping space between them. Each locking block 10 has two screw holes 13. There are also two clamping blocks 20, each with two racetrack-shaped holes 23. Two fixing bolts pass through the racetrack-shaped holes and are installed in the corresponding screw holes, thereby connecting the two locking blocks 10 together. Since a clamping space is formed between the two locking blocks 10, the object to be clamped, i.e., the battery box frame, is restricted between the two locking blocks 10, thus positioning and clamping the object. Because the racetrack-shaped holes have a certain length, clamping operations of objects of different widths can be achieved by passing the fixing bolts through different positions in the racetrack-shaped holes. Since the object to be clamped can be positioned and clamped using only fixing bolts and clamping blocks, quick switching can be achieved, reducing line change time. At the same time, because there are fewer parts, the maintenance cost is also low. Everything else is the same as in Example 1, and will not be repeated here.
[0034] like Figure 5 The diagram shows a scenario where the first and second embodiments are combined. Depending on the different parts of the battery box frame, different structures can be selected to position and clamp the object, so as to facilitate other operations on the object.
[0035] In summary, this utility model, through the above-described structural design, overcomes the shortcomings of the prior art and features a reasonable structure, flexibility, and strong adaptability.
[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
