[0027] See also Figure 1-Figure 4As shown, a variable-distance clamping device of the utility model comprises a mounting plate 1 and at least one set of clamping distance-changing mechanisms, wherein the clamping distance-changing mechanisms comprise a first clamping portion 2, a second clamping portion 3, a linkage member and a driving member mounted on the mounting plate 1, wherein the first clamping portion 2 and the second clamping portion 3 are respectively connected to the mounting plate 1 in a sliding manner along a preset direction, and the driving member is connected to the first clamping portion 2 to drive the first clamping portion 2 to slide along the preset direction. The linkage member comprises a first end and a second end, wherein the first end is fixedly connected or integrally formed with the second clamping portion 3, and the second end is movably matched with a matching structure provided with the first clamping portion 2, so that the first clamping portion 2 can move a preset distance relative to the linkage member in a preset direction, and the preset distance is less than the distance that the first clamping portion 2 slides under the driving of the driving member. Therefore, when the first clamping portion 2 is driven to slide by the driving member, after the first clamping portion 2 moves a preset distance relative to the linkage member, as the first clamping portion 2 continues to slide, the first clamping portion 2 can pull the linkage member to slide, thereby driving the second clamping portion 3 to slide along.

The use of buffering pieces can reduce the impact and noise generated when the linkage rod 6 contacts the first matching piece 5 and the second matching piece 51. The first mating member 5 and the second mating member 51 can be adjusted. Specifically, the distance between the first mating member 5 and the second mating member 51 can be adjusted by adjusting the thread of the buffer member, thereby adjusting the distance that the first clamping jaw portion 2 moves relative to the linkage member (i.e., the linkage rod 6). In other embodiments, the mating structure includes a slide groove extending along the preset direction, and the second end of the linkage member is slidably connected to the slide groove.

[0031] The utility model also includes a third clamping jaw part 4, which is fixedly mounted on the mounting plate 1 and arranged with the first clamping jaw part 2 and the second clamping jaw part 3 along a preset direction, and the second clamping jaw part 3 is located between the first clamping jaw part 2 and the third clamping jaw part 4. The second clamping jaw part 3 includes a second clamping jaw 31 and a second mounting seat 32, the second clamping jaw 31 is mounted on the second mounting seat 32, the second mounting seat 32 is slidably connected to the mounting plate 1 along a preset direction, and is fixedly connected to the first end of the linkage; the third clamping jaw part 4 includes a third clamping jaw 41 and a third mounting seat 42, the third mounting seat 42 is fixedly mounted on the mounting plate 1, and the third clamping jaw 41 is mounted on the third mounting seat 42.

The third jaw part 4 is located between the two groups of jaw pitch changing mechanisms. Therefore, the utility model can achieve five jaw part pitch changes at one time.

[0033] The above-mentioned driving component is preferably a linear driving component, which includes one of a cylinder, an electric push rod and a hydraulic cylinder. Specifically, in this embodiment, the driving component is an example of a cylinder 9, the piston rod of the cylinder 9 is located on one side of the first mounting seat 22, and the rear end of the piston rod of the cylinder 9 is connected to the first mounting seat 22 by a connecting block 91. The two sets of jaw pitch changing mechanisms of the utility model each use a cylinder 9, so the utility model uses a total of two cylinders 9 for jaw pitch changing, and the piston rods of the two cylinders 9 are both located in the left and right directions and extend in opposite directions, that is, the piston rod of the cylinder 9 on the left extends to the left, and the piston rod of the cylinder 9 on the right extends to the right.

[0035] The utility model is a variable-distance clamping device, which can be used to carry a battery 10 (the battery 10 is specifically a square-shell lithium battery). One state of the utility model is as follows Figure 3 As shown, at this time, the distance between the clamping jaws reaches the maximum, and the other state is as follows Figure 4 As shown, at this time, the distance between the clamping jaws reaches the minimum. The switching process between the two states is described below.

[0036] exist Figure 3 When the cylinder 9 is started in this state and the piston rod of the cylinder 9 is retracted, the cylinder 9 drives the first clamping jaw part 2 to slide in the direction close to the second clamping jaw part 3. When the first clamping jaw part 2 moves a preset distance relative to the linkage rod 6, the second end of the linkage rod 6 contacts the second matching piece 51. As the first clamping jaw part 2 continues to slide in the direction close to the second clamping jaw part 3, the first clamping jaw part 2 pushes the linkage rod 6 to move through the second matching piece 51, thereby driving the second clamping jaw part 3 to slide in the direction close to the third clamping jaw part 4 until the second clamping jaw part 3 touches the first limit piece 7 and stops, thereby switching the utility model to the state as shown in FIG. Figure 4 Status shown.

[0037] exist Figure 4When the cylinder 9 is started in this state and the piston rod of the cylinder 9 is extended outward, the cylinder 9 drives the first clamping jaw part 2 to slide in the direction of the second clamping jaw part 3. When the first clamping jaw part 2 moves a preset distance relative to the linkage rod 6, the second end of the linkage rod 6 contacts the first matching piece 5. As the first clamping jaw part 2 continues to slide in the direction away from the second clamping jaw part 3, the first clamping jaw part 2 pushes the linkage rod 6 to move through the first matching piece 5, thereby driving the second clamping jaw part 3 to slide in the direction away from the third clamping jaw part 4 until the second clamping jaw part 3 touches the second limiter 8 and stops, thereby switching the utility model to the state as shown in FIG. Figure 3 The mounting plate 1 may further be provided with a cylinder in-position detector to control the extension / retraction stroke of the piston rod of the cylinder 9 .

[0038] Therefore, the utility model can realize accurate pitch change, and adopts two cylinders 9 to control the pitch change of five batteries at one time, and the overall structure is simple, the adjustment is convenient, and it is economical and practical.
