Description

Technical Field

[0001] The utility model relates to the field of wire harness processing, in particular to a wire cutting device for wire harness processing. Background Art

[0002] Wire harnesses are widely used in current industrial production. Wire harnesses are wiring components that connect various electrical devices in the circuit. They are composed of insulating sheaths, terminal blocks, wires, etc. The wire harnesses produced in the workshop are very long and need to be cut according to different application scenarios. When the existing wire harness cutting device is working, the wire harness is first placed on the processing table, and the cylinder can be used to push the cutting knife to move and press it down to cut the wire harness. During processing, since the wire harness has a certain degree of curvature, the position of the processed part of the wire harness is prone to offset during cutting, resulting in a large deviation in the length of the wire harness after cutting, resulting in low overall cutting accuracy. Utility Model Content

[0003] In view of the above situation, in order to overcome the defects of the prior art, the purpose of the present invention is to provide a wire cutting device for wire harness processing, which has the advantages of solving the problems raised in the above background technology.

[0004] The above technical objectives of the utility model are achieved through the following technical solutions:

[0005] A wire cutting device for wire harness processing comprises a base, the top of the base is fixedly connected to an operating table, one side of the operating table is located on the top surface of the base and is vertically fixedly connected to a support rod, the top of the support rod is fixedly connected to a connecting plate, one end of the connecting plate extends above the operating table, the bottom of the extending end of the connecting plate is fixedly connected to an electric cylinder, the output end of the electric cylinder is vertically arranged downward, a mounting plate is provided at the bottom of the output end of the electric cylinder, a fixing plate is provided at the bottom of the mounting plate, a tool holder is provided at the bottom of the fixing plate, a cutting knife is installed at the bottom of the tool holder, a cutting groove is provided on the top surface of the operating table below the cutting knife, symmetrical V-shaped grooves are provided on both sides of the cutting groove, a mounting frame is provided on the top of the V-shaped groove, a clamping screw is threadedly connected to the top of the mounting frame, a clamping block is rotatably connected to the bottom of the clamping screw, and an arc groove is provided at the bottom of the clamping block.

[0006] By adopting the above technical solution, during operation, the operator places the wire harness to be cut in the V-groove, and moves the part of the wire harness to be cut to the cutting groove. Then the operator simultaneously turns the clamping screw on the mounting frame to drive the clamping block to move downward to the surface of the wire harness. The arc groove provided at the bottom of the clamping block fits with the surface of the wire harness and is clamped and fixed to avoid sliding during the cutting operation and affecting the cutting effect. During the cutting operation, the operator turns on the electric cylinder to drive the fixed plate and the knife holder at the bottom of the fixed plate to move downward, and cooperates with the cutter to complete the cutting operation of the wire harness. During the cutting process, the cooperation of the cutting groove and the cutter can play a buffering role, avoiding the cutter from directly hitting the operating table to cause damage and affect the progress of the operation.

[0007] It is further configured that a buffer pad is fixedly connected to the bottom of the groove.

[0008] By adopting the above technical solution, the cutter will extend into the cutting groove during cutting operations, and the buffer pad provided at the bottom of the cutting groove will play a buffering and protective role, thereby avoiding damage to the cutter and affecting the operation.

[0009] It is further configured that a buffer assembly is provided between the bottom of the mounting plate and the fixed plate, and the buffer assembly includes a plurality of damping rods provided between the mounting plate and the fixed plate, and a buffer spring is sleeved on the outer side of the plurality of damping rods.

[0010] By adopting the above technical solution, during the cutting operation, the operator turns on the electric cylinder to drive the fixed plate and the knife holder at the bottom of the fixed plate to move downward, and cooperates with the cutter to complete the cutting operation of the wire harness. During the cutting operation, the cutter is subjected to a certain pressure, and the multiple damping rods and buffer springs arranged between the mounting plate and the fixed plate cooperate to play a supporting and buffering role, thereby improving the cutting operation efficiency.

[0011] It is further configured that: an arc-shaped plate is matched at the bottom of each of the arc-shaped grooves, and a plurality of compression springs are provided between the arc-shaped plate and the arc-shaped groove.

[0012] By adopting the above technical solution, when the arc plate moves downward in coordination with other components to clamp and fix the surface of the wire harness, the arc plate fits with the surface of the wire harness through the setting of the arc plate, and the pressure is increased by squeezing multiple compression springs to ensure the compression of the wire harness and prevent the pulley from affecting the cutting operation.

[0013] It is further configured that: a plurality of anti-slip bumps are fixedly connected to the bottom of the arc-shaped plate.

[0014] By adopting the above technical solution, during the clamping and fixing operation, the arc plate cooperates with other components to fit the surface of the wire harness and clamp it, and the multiple anti-slip bumps on the arc plate contact the surface of the wire harness to increase friction and avoid movement that affects the cutting operation.

[0015] It is further configured that the inner walls of the V-shaped grooves are fixedly connected with anti-slip pads.

[0016] By adopting the above technical solution, when the wire harness is placed in the V-shaped groove, the friction is increased by the contact between the anti-skid pad and the surface of the wire harness, thereby preventing movement from affecting the cutting operation.

[0017] In summary, the utility model has the following beneficial effects:

[0018] When the utility model is in operation, the operator places the wire harness to be cut in the V-groove, and moves the part of the wire harness to be cut to the cutting groove. Then the operator simultaneously turns the clamping screw on the mounting frame to drive the clamping block to move downward to the surface of the wire harness, and the arc plate in the arc groove at the bottom of the clamping block fits and fixes the surface of the wire harness, and the pressure is increased by squeezing multiple clamping springs to ensure the clamping of the wire harness, avoiding the pulley from affecting the cutting operation. When the arc plate fits the surface of the wire harness, the friction is increased by setting multiple anti-skid protrusions on the surface of the wire harness to contact and increase the friction, thereby avoiding the movement of the wire harness during the cutting operation and affecting the cutting operation.
