Description

Technical Field

[0001] The utility model relates to the technical field of wire grasping and shearing, in particular to a wire grasping and shearing device. Background Art

[0002] As a common power material, wires often need to be stored in and retrieved from the distribution network warehouse. Since the length of wires used is relatively flexible, there are often remaining loose pieces. It is very inconvenient to rewind the loose pieces back onto the wire reel for storage. Therefore, in actual operation, the loose pieces are generally directly stacked in the corner of the warehouse when they are stored. When stacking the loose pieces, the length of the loose pieces needs to be adjusted according to the actual situation and the wire ends need to be cut off. The current adjustment method is that workers need to use bolt cutters to cut first and then store them. The labor intensity of the operator is high. When the wire diameter is relatively thick or the mechanical strength of the wire is relatively large, it is very difficult to cut the wire manually.

[0003] Therefore, there is an urgent need for a wire grasping and shearing device to solve the deficiencies in the prior art. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the deficiencies of the prior art and provide a wire grasping and shearing device to improve the efficiency of the storage and retrieval of electric power fittings.

[0007] The wire clamping device includes a pneumatic finger connected to the main support plate and a clamping piece sleeved on the clamping jaw of the pneumatic finger; the wire cutting device includes a piston driven by a hydraulic system, two scissor blades, and a connecting rod connecting the piston and the two scissor blades; the connecting rod is divided into two groups, each group of connecting rods is respectively connected to the end of the piston and the upper end of one blade, and each group of connecting rods is composed of two connecting blocks. The upper connecting block is hinged to the piston at one end, the lower connecting block is hinged to the free end of the upper connecting block at one end, and the free end of the lower connecting block is fixedly connected to the upper end of the blade; the position of the clamping piece corresponds to that of the blade.

[0008] Preferably, a plurality of support plates are arranged on one side of the main support plate, and a pressing plate is detachably connected to each support plate correspondingly. The wire cutting device is sleeved between the pressing plate and the support plate.

[0009] Preferably, a plurality of friction pieces are arranged at equal intervals on the inner side of the clamping piece, and the friction pieces are arc-shaped on the contact surface with the loose wire.

The connecting rod 52 is divided into two groups, and the two groups of connecting rods 52 are arranged in layers. Each group of connecting rods 52 is respectively connected to the end of the piston 51 and the upper end of a blade 53. Each group of connecting rods 52 is composed of two connecting blocks.
