Description

Technical Field

[0001] The utility model relates to a novel material clamping device, belonging to the technical field of material taking equipment. Background Art

[0002] When the workpiece is transferred between different workstations, it will be grasped by a clamping device with a forward component. The traditional clamping device, such as the clamping device disclosed in patent number "CN220388402U", is designed to install two clamping jaws on a bidirectional screw. Rotating the bidirectional screw can synchronously adjust the spacing between the clamping jaws so that the two clamping jaws can clamp the two sides of the workpiece respectively. However, for some irregular workpieces, this design is not completely applicable, specifically, because the clamping jaws need to adjust their own positions individually to find a suitable clamping point.

[0003] Therefore, the applicant designed a new type of clamping device and filed the following application. Utility Model Content

While the grabbing components transport the workpiece with the help of the forward component, the push-pull cylinder provided on the mounting seat can flip the grabbing components to raise the height of the workpiece from the ground.

[0006] Preferably, the material grabbing assembly includes a clamping claw slidably arranged on the auxiliary plate, and the auxiliary plate and the mounting seat are hinged to each other through a flip block, and the cylinder shaft of the push-pull cylinder can push and pull the flip block to drive the clamping claw to flip.

[0007] Preferably, the sub-plate of the material grabbing assembly is also equipped with a mini cylinder for driving the clamping claws to slide and clamp the material.

[0008] Preferably, the solid screw has a smooth section formed thereon for sleeve-fitting with the hollow screw. When the hollow screw and the solid screw are sleeved with each other, the outer surfaces of the threaded parts of the two screws are flush with each other.

[0010] Preferably, the inner side of the adjusting platform has a pad for supporting the hollow screw and the solid screw.

[0011] Preferably, the forward component is a slider that slidably cooperates with the guide rod, and the adjustment platform with the material grabbing component is fixed on the top surface of the slider.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figure 1-Figure 3 As shown: a new type of clamping device includes two sets of gripping components 1. The gripping components 1 can move downward to clamp the two sides of the workpiece, and realize the workpiece transportation and transfer action through the forward component 2.

[0022] Furthermore, the above-mentioned two groups of grabbing components 1 are installed in the same direction on an adjusting platform 3, and a hollow screw 301 and a solid screw 302 are coaxially sleeved in the adjusting platform 3. The two screws are respectively combined with a grabbing component 1 through a mounting seat 4 with a nut block, and can rotate by themselves to adjust the position of the corresponding grabbing component 1 to find a suitable clamping point for the workpiece.

[0023] Specifically, the part of the solid screw 302 used to be socketed with the hollow screw 301 is a smooth section with a smooth surface. When the two screws are socketed with each other, the outer surfaces of the threaded parts are flush with each other; at the same time, the two sides of the adjusting platform 3 are provided with support seats 303 for supporting the screws, and the inner side of the support seat 303 is provided with a soft rubber pad 313. After the extended sections formed by the two screws in the same side direction pass outward from the pad 313 and the support seat 303, a rotating wheel 304 is respectively installed at the end position. Rotating the rotating wheel 304 can rotate the corresponding screw, thereby independently adjusting the above-mentioned grabbing assembly 1.

[0024] Furthermore, the material gripping assembly 1 comprises a clamping jaw 101 combined with a mounting base 4 through a sub-plate 102, and the sub-plate 102 also has a mini cylinder 112 that can push the clamping jaw 101 to slide slightly linearly. When the clamping jaw 101 is located above the workpiece, it can be pushed to move downward horizontally to clamp the workpiece. In addition, since the workpiece is transferred between different workstations, in order to avoid collision during the transfer process, the material gripping assembly 1 also has a flipping function, such as Figure 2 As shown, the sub-plate 102 for mounting the clamp 101 is hinged to the mounting base 4 via a flip block 122. When the push-pull cylinder 401 provided on the mounting base 4 extends or retracts the cylinder shaft, the flip block 122 can be pushed and pulled, thereby driving the clamp 101 to flip accordingly, so that the workpiece is lifted to a certain height.

[0025] Furthermore, the above-mentioned forward component 2 for realizing the transfer of workpiece transportation is specifically a slider 201 fixed to the bottom surface of the adjusting platform 3. The slider 201 is slidably connected with a guide rod 202 provided on the frame (not shown in the figure). The slider 201 can be driven by an external drive to drive the clamping jaw 101 to reciprocate between the two workstations to transfer the clamped workpiece.

[0026] Working method: First, rotate the wheel to adjust the position of the clamp until it is located at the appropriate clamping point to clamp the workpiece; then, the workpiece is transported to another workstation with the help of the forward component, and temporarily turned over on the way to avoid collision; finally, when the workpiece arrives at the designated workstation, the clamp will place it in it for the next processing step.

[0027] As mentioned above, the existing clamping device may not have a good clamping effect on some special-shaped workpieces; for example, one side of the workpiece has an obvious raised feature. Since the two clamping jaws adjusted by the bidirectional screw move synchronously, one of the clamping jaws will be forced to clamp on the raised feature. The clamping position here does not fit the clamping jaw, so the clamping is unstable. It is necessary to find a suitable clamping point for the clamping jaw. In response to this technical problem, this design retains the use of the traditional clamping device while giving the two clamping jaws the ability to adjust independently, so that it can stably clamp and transport such special-shaped workpieces, and has higher applicability overall.

Unless otherwise defined, the technical terms or scientific terms used in this utility model should be understood by people with ordinary skills in the field. Unless otherwise specified, the words "upper", "lower", "front", "back" and the like are only for the convenience of description and are not limited to a position or a spatial orientation.
