It aims to solve the problem in the prior art that a large amount of waste chips will be generated during the cutting process of wire harness plates. The waste chips are easily scattered around when the cutter rotates, causing pollution to the environment and inconvenient cleaning. A protective cover is installed on one side of the drive box, and the protective cover is fixedly connected to the drive box by fastening screws. A cutting knife is provided inside the protective cover. A collection bin is installed above the base, and the collection bin is fixedly connected to the base by bolts. A first motor is installed above the base, and the first motor is fixedly connected to the base by bolts.

[0004] The above patent has the function of collecting waste generated during the cutting process, which helps to reduce the subsequent cleaning burden. However, when cutting automotive wiring harnesses, the rotating cutting of the circular saw blade will apply tangential and radial forces to the wiring harness. In this case, only one end of the wiring harness is fixed, resulting in the tangential force pushing the wiring harness to move laterally, resulting in the need for manual correction in the subsequent cutting process, resulting in a decrease in cutting efficiency. Summary of the Invention

The wire harness is pulled by cooperating with the clamping block and the conveying roller, which can not only meet different cutting requirements, but also prevent the wire harness from being offset due to the tangential force of the circular saw cutter during the cutting process.

[0007] According to the above technical solution, a groove is provided on the surface of the clamping block, and the connecting rod provides support for the clamping block to ensure that the clamping block stably clamps the wire harness through the groove. An arc-shaped blade is fixedly installed in the groove, and a rectangular groove is provided on the outer wall of the sliding platform. The arc-shaped blade forms a high-friction engagement with the wire harness to ensure that when the clamping block pulls the wire harness, the wire harness will not slip and affect the cutting accuracy.

[0008] According to the above technical solution, a conveying roller is rotatably installed on the inner wall of the fixed plate, and friction is generated between the wire harness and the conveying roller. The conveying roller rotates under the action of the friction force. A through hole is opened on the surface of the clamping block, and the clamping block is slidingly connected to the connecting rod through the through hole. The conveying roller is in close contact with the wire harness to ensure stable transportation of the wire harness.

[0009] According to the above technical solution, a long rod is fixedly installed on the surface of the sliding platform, and the sliding platform moves along the guide rail in the direction away from the conveying roller. The sliding platform drives the long rod to move synchronously. The side of the long rod away from the sliding platform is provided with an arc surface. By providing the arc surface, it is ensured that the long rod can successfully complete subsequent work.

According to the above technical solution, the auxiliary device includes a base plate, which is fixedly installed on the surface of the fixed plate, and a guide groove is provided on the top of the base plate. A support rod is slidably installed in the guide groove, and a connecting plate is fixedly installed on the circumferential surface of the support rod. A collision rod is fixedly installed on the circumferential surface of the support rod, and a convex piece is fixedly installed on the top of the base plate. The connecting plate drives the connecting plate to move toward the convex piece.

Power is provided by the connecting plate to achieve stable collision between the impact rod and the convex piece to generate vibration, and then transmit the vibration to improve the smoothness of the movement of the long rod in the linear bearing.

[0011] According to the above technical solution, a linear bearing is fixedly installed on the top of the base plate, and a guide frame is fixedly installed on the outer side wall of the linear bearing. The linear bearing contacts the circumferential surface of the long rod. When the long rod is out of contact with the linear bearing, the linear bearing releases the support provided to the long rod. By adding a guide frame to the linear bearing, the long rod is guided to pass through the linear bearing, thereby ensuring the smooth implementation of the support function and preventing the long rod from deviating and causing unexpected risks.

[0012] According to the above technical solution, a conical surface is provided on one side of the impact rod close to the convex piece, and the conical surface of the impact rod collides with the outer wall of the convex piece.

[0013] The present invention provides a cutting device for a wire harness assembly, which has the following beneficial effects: (1) In the cutting device of the wire harness assembly, the arc blade contacts the surface of the wire harness and cuts into the surface, so that the arc blade and the wire harness form a high friction bite, ensuring that when the clamping block pulls the wire harness, the wire harness will not slip and affect the cutting accuracy. The pre-cut marks formed on the surface of the wire harness can also improve the subsequent wire stripping efficiency. At the same time, the clamping block pulls the wire harness axially, and the wire harness and the conveying roller generate friction.

The centering function of the rubber plate can effectively reduce the deflection of the wire harness, ensure that the clamping block can stably clamp the wire harness, eliminate the manual correction step, and help enhance the automation of cutting.

[0015] (3) In the cutting device of the harness assembly, the guide frame guides the long rod to smoothly enter the linear bearing, ensuring that the linear bearing can smoothly provide support for the long rod. By adding a guide frame to the linear bearing, the long rod is guided to pass through the linear bearing, ensuring the smooth implementation of the support function and preventing the long rod from deviating and causing unexpected risks. At the same time, the impact rod collides with the convex piece, and the vibration generated by the collision is transmitted to the linear bearing through the convex piece.

[0018] The following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0019] See also Figure 1-Figure 5 One embodiment of the present invention is: a cutting device for a wire harness assembly, comprising an outer frame 1, a lifting device 21 is provided on the top of the outer frame 1, a circular saw cutter 22 is provided on the movable end of the lifting device 21, wherein the outer frame 1 is provided with a wire pulling device, the wire pulling device comprising: a fixed plate 3, the fixed plate 3 is fixedly mounted on the surface of the outer frame 1, and the surface of the fixed plate 3 is provided with a slide rail; a linear drive device 4, the linear drive device 4 is arranged on the inner wall of the fixed plate 3; a sliding platform 5, the sliding platform 5 is threadedly connected to the output end of the linear drive device 4, and the bottom of the sliding platform 5 is slidably connected to the slide rail; a connecting rod 6, the connecting rod 6 is fixedly mounted on the outer wall of the sliding platform 5; a cylinder 7, the cylinder 7 is fixedly mounted on the inner wall of the sliding platform 5; a clamping block 8, the clamping block 8 is fixedly mounted on the output end of the cylinder 7, and when the cylinder 7 is started, its output end drives the clamping block 8 to perform a clamping action. By cooperating with the clamping block 8 and the conveying roller 10 to pull the wire harness, it can not only meet different cutting requirements, but also prevent the wire harness from being offset due to the tangential force of the circular saw cutter 22 during the cutting process.

[0020] A groove is provided on the surface of the clamping block 8, and the connecting rod 6 provides support for the clamping block 8 to ensure that the clamping block 8 stably clamps the wire harness through the groove. An arc-shaped blade 9 is fixedly installed in the groove, and a rectangular groove is provided on the outer wall of the sliding platform 5. The arc-shaped blade 9 forms a high-friction bite with the wire harness to ensure that when the clamping block 8 pulls the wire harness, the wire harness will not slip and affect the cutting accuracy.

[0021] A conveying roller 10 is rotatably installed on the inner wall of the fixed plate 3. Friction is generated between the wire harness and the conveying roller 10. The conveying roller 10 rotates under the action of the friction. A through hole is provided on the surface of the clamping block 8. The clamping block 8 is slidingly connected to the connecting rod 6 through the through hole. The conveying roller 10 is in close contact with the wire harness to ensure stable transportation of the wire harness.

[0022] A long rod 11 is fixedly installed on the surface of the sliding platform 5. The sliding platform 5 moves along the guide rail in the direction away from the conveying roller 10. The sliding platform 5 drives the long rod 11 to move synchronously. The side of the long rod 11 away from the sliding platform 5 is provided with an arc surface. By providing the arc surface, it is ensured that the long rod 11 can successfully complete subsequent work.

[0023] When this embodiment is working, the wire harness is manually pulled to move to the preset position through the conveying roller 10, and the cylinder 7 is started, and its output end drives the clamping block 8 to perform the clamping action. At this time, the connecting rod 6 provides support for the clamping block 8 to ensure that the clamping block 8 stably clamps the wire harness through the groove. After the clamping action is completed, the linear drive device 4 is started to drive the sliding platform 5 to translate along the guide rail in the direction away from the conveying roller 10, and the sliding platform 5 drives the cylinder 7, the clamping block 8 and the long rod 11 to translate synchronously; in this process, the clamping block 8 pulls the wire harness axially for displacement, and at this time the wire harness and the conveying roller 10 generate friction, and the conveying roller 10 rotates under the action of friction to ensure stable transportation of the wire harness; when the sliding platform 5 reaches the set cutting length position, the lifting device 21 drives the circular saw cutter 22 to cut vertically to cut the wire harness. When the wire harness is cut, the wire harness in close contact with the conveying roller 10 will not deviate at a large angle, and the cutting After completion, the lifting device 21 automatically resets, and the cylinder 7 drives the clamping block 8 to release the clamping, and the material is taken manually. The clamping block 8 and the conveying roller 10 cooperate to pull the wire harness, which can not only meet different cutting requirements, but also prevent the wire harness from being offset due to the tangential force of the circular saw cutter 22 during the cutting process, thereby ensuring the smooth progress of subsequent cutting. When the cylinder 7 drives the clamping block 8 to close, the arc-shaped blade 9 in its groove contacts the surface of the wire harness and cuts into the surface, thereby enhancing the clamping force of the clamping block 8 on the wire harness and preventing the wire harness from slipping during the traction process. After the cutting is completed, the arc-shaped blade 9 disengages from the wire harness together with the clamping block 8. The pre-cut marks formed on the surface of the wire harness can improve the efficiency of subsequent wire stripping, and the high friction bite formed by the arc-shaped blade 9 and the wire harness ensures that when the clamping block 8 pulls the wire harness, the wire harness will not slip and affect the cutting accuracy. The pre-cut marks formed on the surface of the wire harness can also improve the efficiency of subsequent wire stripping.

A linkage block 207 is fixedly installed at the bottom of the connecting plate 206. A slope is provided on the side of the linkage block 207 close to the long rod 11. The slope of the linkage block 207 contacts the arc surface of the long rod 11. The arc surface of the long rod 11 and the slope of the linkage block 207 gradually separate. The stretched spring 204 begins to contract under the action of the elastic restoring force. The centering positioning function of the rubber plate 205 can effectively reduce the deflection of the wire harness, ensure that the clamping block 8 can stably clamp the wire harness, eliminate the step of manual correction, and facilitate enhanced cutting automation. The auxiliary device includes a base plate 301, which is fixedly mounted on the surface of the fixed plate 3, and a guide groove is provided on the top of the base plate 301, in which a support rod 302 is slidably installed, and a connecting plate 303 is fixedly mounted on the circumferential surface of the support rod 302, and a collision rod 304 is fixedly mounted on the circumferential surface of the support rod 302, and a convex piece 305 is fixedly mounted on the top of the base plate 301, and the connecting plate 206 drives the connecting plate 303 to move toward the convex piece 305, and a circular hole is provided on the top of the connecting plate 303, and the connecting plate 303 is fixedly connected to the circumferential surface of the connecting plate 206 through the circular hole, and power is provided by the connecting plate 206 to achieve stable collision between the collision rod 304 and the convex piece 305 to generate vibration, and then transmit the vibration to improve the smoothness of the movement of the long rod 11 in the linear bearing 306.

[0025] A linear bearing 306 is fixedly installed on the top of the base plate 301, and a guide frame 307 is fixedly installed on the outer wall of the linear bearing 306. The linear bearing 306 contacts the circumferential surface of the long rod 11. When the long rod 11 is out of contact with the linear bearing 306, the linear bearing 306 releases the support provided for the long rod 11. By adding a guide frame 307 to the linear bearing 306, the long rod 11 is guided to pass through the linear bearing 306, thereby ensuring the smooth implementation of the support function and preventing the long rod 11 from deviating and causing unexpected risks.

[0026] A conical surface is provided on one side of the impact rod 304 close to the convex piece 305. The conical surface of the impact rod 304 collides with the outer wall of the convex piece 305. The vibration generated in the collision is transmitted to the linear bearing 306 through the convex piece 305. The convex piece 305 itself is elastic. By setting up the elastic convex piece 305, the collision vibration work can be used for a long time.

[0027] When the present embodiment is working, when the sliding platform 5 drives the long rod 11 to move away from the mounting bracket 201, the arc surface of the long rod 11 gradually separates from the inclined surface of the linkage block 207, and the stretched spring 204 begins to contract under the action of the elastic restoring force, pulling the round rod 203 to move toward the hollow tube 202, and the round rod 203 drives the rubber plate 205 and the connecting plate 206 to move synchronously, and the connecting plate 206 further drives the linkage block 207 to move synchronously until the rubber plate 205 moves to the designated position and stands by. At this time, the rubber plate 205 is out of contact with the wire harness, ensuring that the wire can be transported freely. When the cutting is completed, the sliding platform 5 drives the long rod 11 to the mounting bracket 201. The round rod 203 moves in the direction of rotation, the arc surface of the long rod 11 contacts the inclined surface of the linkage block 207 and applies a lateral thrust. The linkage block 207 pushes the connecting plate 206 to move the round rod 203 away from the hollow tube 202. The round rod 203 stretches the spring 204 during the movement to store energy. At the same time, the round rod 203 drives the rubber plate 205 to move synchronously, so that the rubber plate 205 contacts the wire harness. At this time, the rubber plate 205 moves to center the wire harness to ensure that the wire harness is stably straightened. The centering positioning function of the rubber plate 205 can effectively reduce the deflection of the wire harness, ensure that the clamping block 8 can stably clamp the wire harness, eliminate the step of manual correction, and help enhance the automation of cutting. When the long rod 11 moves in the direction away from the linear bearing 306, the long rod 11 is out of contact with the linear bearing 306, and the linear bearing 306 releases the support provided for the long rod 11; when the long rod 11 is reset, the long rod 11 contacts the inner wall of the guide frame 307 during movement, and the guide frame 307 guides the long rod 11 to smoothly enter the linear bearing 306, ensuring that the linear bearing 306 can smoothly provide support for the long rod 11. By adding a guide frame 307 to the linear bearing 306, the long rod 11 is guided to pass through the linear bearing 306, thereby ensuring the smooth implementation of the support function and preventing the long rod 11 from deviating and causing unexpected risks.

The long rod 11 in contact with the linear bearing 306 moves more smoothly under the action of vibration, and the power is provided by the connecting plate 206 to achieve stable collision between the impact rod 304 and the convex piece 305 to generate vibration, and then transmit the vibration to improve the smoothness of the movement of the long rod 11 in the linear bearing 306.
