[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0021] Reference Figure 1 and Figure 2 As shown, a clamping device of this utility model includes: a clamping member 4; a connecting frame 3, wherein two connecting frames 3 are provided, and movable rods 7 are slidably connected to opposite sides of the two connecting frames 3, the ends of the movable rods 7 are connected to the clamping member 4, and elastic members 71 are sleeved on the movable rods 7, the two ends of the elastic members 71 respectively abut against the connecting frame 3 and the clamping member 4, and a clamping space is formed between the two clamping members 4; a driving member, the output end of which is connected to the connecting frame 3, and the two connecting frames 3 can move in a direction that approaches or moves away from each other.

[0022] In this embodiment of the clamping device, after the material to be clamped is positioned between the clamping members 4, the driving member drives the connecting frame 3 to move in a direction of mutual approach, thereby causing the clamping members 4 to move in the same direction. After the two clamping members 4 come into contact with the material to be clamped, the elastic member 71 is compressed, and the clamping members 4 complete the clamping of the material to be clamped. At this time, the position of the clamped material is fixed. Through the cooperation of the driving member and the clamping members 4, the position of the material to be clamped is fixed, thereby maintaining stability during the movement of the material to be clamped. The elastic member 71 can buffer the clamping process of the clamping members 4, preventing damage to the material to be clamped during the clamping process.

[0023] Clamping member 4 is used to clamp the material to be clamped. Two clamping members 4 are provided and arranged opposite each other, forming a clamping space between them. The opposite sides of the clamping members 4 are provided with grooves 41, which are arc-shaped. This allows for a larger contact area between the grooves 41 and the material when clamping cylindrical materials, resulting in more stable clamping and preventing deformation of the material. In another embodiment, depending on the material to be clamped, the grooves 41 can also be rectangular, conical, etc. Weight-reducing through holes are also provided at the included angle of the clamping members 4, thereby reducing the weight of the clamping members 4 and thus reducing the load on the driving component.

[0024] The connecting frame 3 is used to connect with the clamping member 4, and the connecting frame 3 is generally L-shaped. Two connecting frames 3 are provided and arranged opposite each other. Movable rods 7 are slidably connected to the opposite sides of the connecting frame 3. The ends of the movable rods 7 are connected to the clamping member 4, and elastic elements 71 are sleeved on the movable rods 7. The two ends of the elastic elements 71 abut against the connecting frame 3 and the clamping member 4, respectively. Specifically, there are two movable rods 7, and guide members 5 are connected to the connecting frame 3. The guide members 5 can be considered as linear bearings, and they pass through the connecting frame 3. The movable rods 7 are slidably connected to the guide members 5. The elastic elements 71 can be considered as springs, and their two ends abut against the guide members 5 and the clamping member 4, respectively. When the clamping member 4 moves towards the connecting frame 3, the elastic elements 71 compress, thus buffering the movement of the clamping member 4.

[0025] A first baffle 51 is provided at the end of the guide member 5 away from the connecting frame 3. The first baffle 51 is located on the moving path of the movable rod 7 and has a limiting effect on the movement of the movable rod 7, thereby limiting the movement range of the clamping member 4. Preferably, the end of the movable rod 7 away from the clamping member 4 is connected to the first baffle 51. The movable rod 7 passes through the guide member 5, and the first baffle 51 can abut against the end of the guide member 5. That is, the size of the first baffle 51 is larger than the end size of the guide member 5. The setting of the first baffle 51 can prevent the movable rod 7 from disengaging from the guide member 5 during the spring's rebound after compression. In other words, the first baffle 51 can prevent the clamping member 4 from disengaging from the connecting frame 3.

[0026] Preferably, the two guide members 5 are located on the connecting frame 3 near the end. The connecting frame 3 is also connected to a stop block 6. The stop block 6 is located on the side of the connecting frame 3 near the clamping member 4. There are two stops block 6 and they are located between the two guide members 5. The stops block 6 is cylindrical and there is a certain distance between the two stops block 6. The clamping member 4 can abut against the stops block 6. The stops block 6 is used to limit the movement path of the clamping member 4 and prevent the clamping member 4 from colliding with the guide member 5, which would cause the position of the guide member 5 to shift.

[0027] It also includes a support frame 1, one side of which is connected to a slide rail, and one side of the slide plate 2 is connected to a slider. The slider is slidably connected to the slide rail, thereby allowing the support frame 1 to be slidably connected to the slide plate 2 via the slide rail. Two slide plates 2 are slidably connected to the slide rail, and one side of the connecting frame 3 is connected to the slide plate 2, thereby allowing the connecting frame 3 to be slidably connected to the support frame 1.

[0028] The drive unit is connected to the support frame 1. The output end of the drive unit passes through the support frame 1 and is connected to the slide plate 2. Specifically, the drive unit is located in the accommodating space of the support frame 1. The drive unit can be regarded as a motor and a two-way lead screw. The output end of the motor is connected to the two-way lead screw. A slide groove is provided on the side of the support frame 1 that is connected to the slide rail. The movable nut of the two-way lead screw passes through the slide groove and is connected to the slide plate 2, so that the drive unit can drive the slide plate 2 to move, and then drive the clamping member 4 to move towards each other or away from each other, that is, the clamping member 4 can complete the clamping and releasing actions.

[0029] The support frame 1 is also connected to a second baffle 11 and a third baffle 12. The second baffle 11 is connected to the top edge of the support frame 1 and is set along the moving path of the slide plate 2. The second baffle 11 can prevent external dust, debris, etc. from falling onto the slide rail. The third baffle 12 is located at the end of the slide rail. The third baffle 12 is perpendicularly connected to the support frame 1 and is located at both ends of the slide rail. The third baffle 12 can prevent external debris from entering between the slide plate 2 and the support frame 1. The slide plate 2 can abut against the third baffle 12, thereby limiting the movement range of the slide plate 2 and preventing the slide plate 2 from leaving the slide rail.

[0030] It also includes a detection element 9 and a sensing element 8. The detection element 9 can be regarded as a proximity switch. The detection element 9 is connected to the controller and is located on the second baffle 11. The mounting plate 31 is connected to the included position of the connecting frame 3. The sensing element 8 is connected to the mounting plate 31, so that the sensing element 8 can move with the connecting frame 3. The detection end of the detection element 9 is facing the moving path of the sensing element 8. When the sensing element 8 moves to the position of the detection element 9, the controller controls the connecting frame 3 to stop moving. At this time, the clamping element 4 is in the clamping position.

[0031] In use, the clamping device is connected to the external forks. The external forks move so that the material to be clamped is located between the clamping members 4. The driving member drives the connecting frame 3 to move in a direction of mutual approach, thereby causing the clamping members 4 to move in a direction of mutual approach. When the sensing member 8 moves to the position of the detection member 9, the two clamping members 4 abut against the material to be clamped, the elastic member 71 is compressed, and the clamping members 4 complete the clamping of the material to be clamped. At this time, the position of the clamped material is fixed. When the material needs to be released, the driving member drives the clamping members 4 to move in a direction of mutual distance until the clamping members 4 abut against the stop 6 and the first baffle 51 abuts against the guide member 5. At this time, the material can move.

[0032] This utility model discloses a clamping device that, through the cooperation of a driving component and a clamping component 4, fixes the position of the material to be clamped, thereby maintaining stability during the movement of the material. The elastic component 71 provides a buffering effect during the clamping process of the clamping component 4, preventing damage to the material to be clamped. The stop block 6 restricts the movement path of the clamping component 4, preventing collisions between the clamping component 4 and the guide component 5 that could cause the guide component 5 to shift position.

[0033] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
