For example, the utility model patent with the authorization announcement number CN220179370U on December 15, 2023 announced a three-finger clamp for grasping coil cylinders, which disclosed a three-finger cylinder. When multiple coils need to be clamped in batches, if multiple finger cylinders or multiple pneumatic finger clamps are installed, sufficient space is required, which is not applicable to environments with high space utilization; and the cost is high.

Figure 4 , Figure 7 The upper end surface of the bottom plate 2 is provided with four mutually parallel switching rod grooves 3, and four fixed clamping claws 4 are fixed below one side of each switching rod groove 3, and the fixed clamping claws 4 extend from the top to the bottom of the bottom plate 2, as shown in FIG. Figure 1 As shown, and extending out of the bottom of the base plate 2;

[0027] Four clamping jaw switching rods 5, four guiding inclined surfaces 6 are arranged on the same side of the four clamping jaw switching rods 5, and are driven by the same cylinder 7 to move back and forth along the switching rod slot 3;

[0028] Sixteen movable jaws 8, each movable jaw 8 is slidably disposed on the switch rod slot 3. In this embodiment, four movable jaws 8 are provided on one side of each switch rod slot 3 and are respectively located on one side of four guide slopes 6. An inclined top block 9 is integrally formed at the upper end of each movable jaw 8. The inclined top block 9 matches the guide slope 6. Four elastic members forcing the inclined top block 9 to lean against the guide slope 6 are provided between each of the four movable jaws 8 and the switch rod slot 3.

[0029] When the cylinder 7 drives the four clamping jaw switching rods 5 to move synchronously away from the cylinder 7, the guide slope 6 on each clamping jaw switching rod 5 forces the four movable clamping jaws 8 to move away from the four fixed clamping jaws 4, and the four elastic members are compressed, that is, the sixteen pairs of clamping jaws are in a loose state;

[0030] When the cylinder 7 drives the four clamping jaws switching rods 5 to move synchronously toward the cylinder 7, the sixteen elastic members release their elastic force, forcing the sixteen movable clamping jaws 8 to approach the sixteen fixed clamping jaws 4. At this time, the sixteen pairs of clamping jaws are in a clamped state.

[0031] The same end of each clamping jaw switching rod 5 in this embodiment is detachably connected to the connecting rod 10, the telescopic shaft of the cylinder 7 is detachably connected to the middle part of the connecting rod 10, the same end of the four switching rod grooves 3 is provided with a sliding groove 11 connected thereto, and the cover plate 1 is provided with a sliding through hole 12, the width of the sliding groove 11 and the sliding through hole 12 are both greater than the width of the connecting rod 10, the width of the sliding through hole 12 is less than or equal to the width of the sliding groove 11, and the connecting rod 10 can move back and forth in the sliding through hole 12 and the sliding groove 11.

[0032] The elastic member in this embodiment is a spring 13. Figure 6 As shown, two springs 13 are provided, which are respectively located on one side of the movable clamping jaw 8 and one side of the inclined top block 9. The inclined top block 9 and the movable clamping jaw 8 are provided with spring mounting grooves 14, and the same ends of the two springs 13 are respectively located in the two spring mounting grooves 14.

[0033] like Figure 7 As shown, a spring partition 15 is detachably installed in the switch rod groove 3. The spring partition 15 includes a plurality of equal height portions 15a of the same height as the bottom plate 2 and a partition portion 15b for connecting two adjacent equal height portions 15a. The two springs 13 are respectively located above and below the partition portion 15b.

The second vertical surface 8c cooperates with the fixed jaw vertical surface 4a to clamp the coil 16.

[0035] The working principle of this embodiment is:

[0036] When it is necessary to clamp sixteen coils 16, the cylinder 7 drives the four jaw switching rods 5 to move synchronously in the direction close to the cylinder 7 until the four jaw switching rods 5 stop until the four guide slopes 6 of each jaw switching rod 5 correspond to the slopes of the four slope top blocks 9 on one side, and the four elastic parts force the four guide slopes 6 to always fit with the slopes of the four slope top blocks 9 on one side, and the sixteen movable jaws 8 approach the sixteen fixed jaws 4, and the sixteen coils 16 are clamped at this time.

[0037] When it is necessary to loosen the sixteen coils 16, the cylinder 7 drives the four jaw switching rods 5 to move synchronously away from the cylinder 7, and the four guide slopes 6 of each jaw switching rod 5 pass over the slopes of the four slope top blocks 9. The four slope top blocks 9 are forced to move outward, and the four groups of elastic parts are compressed. As the four slope top blocks 9 move outward, the movable jaws 8 will be driven to move outward, and the sixteen movable jaws 8 will move away from the sixteen fixed jaws 4, and the sixteen coils 16 will be loosened.

It cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
