Description

Technical Field

[0001] The invention relates to the technical field of clamping jaws, in particular to an artificial manual module clamping jaw. Background Art

[0002] In new energy module production lines and pack production lines, grippers are often used to facilitate the up and down handling of materials. However, most of these gripper devices are large in size, heavy in weight, and have no self-locking mechanism. When the cylinder is cut off, the objects clamped by the gripper will automatically fall off, which is prone to safety accidents. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a manual module clamp with simple structure, light weight, strong clamping force, low cost and high safety performance.

[0004] The technical solution adopted by the present invention to solve its technical problems is: to provide a manual module clamp, including a crossbeam and a clamp device, two clamp devices arranged symmetrically with the center are installed on both sides of the lower end of the crossbeam, the clamp device includes a bracket and a clamp, the front and rear sides of the bracket are vertically installed with fixed plates, the middle part of the lower end of the bracket is vertically installed with a cylinder, the piston rod at the lower end of the cylinder is hinged to two first connecting plates, one end of each first connecting plate is hinged with a clamp, the upper and lower sides of the clamp located on the first connecting plate are hinged with second connecting plates, one end of the second connecting plate is hinged to the adjacent fixed plate, the axes of the two second connecting plates and the clamp and the axes of the two second connecting plates and the adjacent fixed plates are arranged in a parallelogram structure.

[0005] As a supplement to the technical solution described in the present invention, a lifting ring is installed in the middle of the upper end of the beam.

[0006] As a supplement to the technical solution described in the present invention, a positioning pin is vertically installed at the lower end of one of the fixing plates of the clamping device.

[0007] As a supplement to the technical solution described in the present invention, a U-shaped fixing frame is installed on the upper end of the clamping device, and the U-shaped fixing frame consists of a horizontal plate and two vertical plates. The lower end of the horizontal plate is fixed to the middle part of the bracket, and the upper end of the horizontal plate is slidably connected to the cross beam. The horizontal plate slides back and forth along the length direction of the cross beam, and each vertical plate is installed with a locking screw, and one end of the locking screw supports the cross beam.

[0008] Beneficial effects: The present invention relates to a manual module clamp. The positioning pin positions the module. When the cylinder contracts, it drives the two hinged first connecting plates. Each of the two first connecting plates has a hinge axis at both ends. The two first connecting plates have four hinge axes in total, so that the four hinge axes form a self-locking mechanism on the same line. The two clamps clamp the module under the action of the tensioning force of the self-locking mechanism; the axes of the two second connecting plates and the clamps and the axes of the two second connecting plates and the adjacent fixed plates are arranged in a parallelogram structure. The two clamps are parallel, so that the module and the clamps achieve surface contact, which greatly enhances the clamping force. Since the self-locking mechanism itself has a large self-locking property, it requires a lot of force from the outside to crack it. Therefore, even in the case of air failure, the clamp can still maintain the clamping function and will not fall off automatically, which has great safety. The present invention also has the advantages of simple structure, light weight, large clamping force, low cost, and high safety performance. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] The present invention will be further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms fall within the scope limited by the appended claims of the application equally.

[0012] The embodiment of the present invention relates to a manual module clamp, such as Figure 1 As shown, it includes a crossbeam 1 and a clamping device, two clamping devices arranged in a central symmetrical manner are installed on both sides of the lower end of the crossbeam 1, and the clamping device includes a bracket 5 and a clamping jaw 8. Fixed plates 6 are vertically installed on the front and rear sides of the bracket 5, and a cylinder 11 is vertically installed in the middle of the lower end of the bracket 5. The piston rod at the lower end of the cylinder 11 is hinged to two first connecting plates 9, and one end of each first connecting plate 9 is hinged to a clamping jaw 8. The clamping jaw 8 is hinged to a second connecting plate 10 on the upper and lower sides of the first connecting plate 9, and one end of the second connecting plate 10 is hinged to the adjacent fixed plate 6. The axes of the two second connecting plates 10 and the clamping jaws 8 are hinged and the axes of the two second connecting plates 10 and the adjacent fixed plates 6 are arranged in a parallelogram structure.

[0013] A lifting ring 2 is installed at the middle of the upper end of the crossbeam 1.

[0014] A positioning pin 7 is vertically mounted on the lower end of one of the fixing plates 6 of the clamping device.

[0015] A U-shaped fixing frame 4 is installed at the upper end of the clamping device, and the U-shaped fixing frame 4 consists of a horizontal plate and two vertical plates. The lower end of the horizontal plate is fixed to the middle of the bracket 5, and the upper end of the horizontal plate is slidably connected to the crossbeam 1. The horizontal plate slides back and forth along the length direction of the crossbeam 1. A locking screw 3 is installed on each vertical plate, and one end of the locking screw 3 supports the crossbeam 1.

[0016] Example

[0017] The positioning pin 7 positions the module. When the cylinder 11 contracts, it drives the two hinged first connecting plates 9. Each of the two ends of the first connecting plates 9 has a hinge axis. The two first connecting plates 9 have four hinge axes in total, so that the four hinge axes form a self-locking mechanism on the same line. The two clamps 8 clamp the module under the action of the tension of the self-locking mechanism; the axes of the hinged two second connecting plates 10 and the clamps 8 and the axes of the hinged two second connecting plates 10 and the adjacent fixed plates 6 are arranged in a parallelogram structure. The two clamps 8 are parallel, so that the module and the clamps are in surface contact, which greatly enhances the clamping force. Since the self-locking mechanism itself has a strong self-locking property, it requires a lot of force from the outside to crack it. Therefore, even in the case of air failure, this clamp can still maintain the clamping function and will not fall off automatically, which has great safety.
