Description

Technical Field

[0001] This utility model relates to the field of wire harness fixing technology, specifically a wire harness cutting and fixing structure. Background Technology

[0002] A wire harness is a component that bundles multiple wires together. With the development of society, there are more and more types of wire harnesses, making their applications more and more widespread. When using wire harnesses, people sometimes use a cutting knife to cut them.

[0003] In the process of realizing this utility model, the inventors found that the following problems in the prior art have not been solved: the existing wire harness cutting and fixing structure does not have the corresponding fixed-length pushing wire harness function, and it mostly relies on personnel to adjust the position of the wire harness according to the scale line for cutting, which is time-consuming and laborious. Moreover, the existing methods are mostly single-group wire harness cutting, which cannot be carried out simultaneously for multiple groups, resulting in unsatisfactory efficiency. Therefore, we propose a wire harness cutting and fixing structure. Utility Model Content

[0004] The purpose of this invention is to provide a wire harness cutting and fixing structure, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a wire harness cutting and fixing structure, comprising a carrier plate, a bottom plate placed on the bottom of the carrier plate, and side plates fixedly installed on both sides of the bottom plate;

[0006] Both sets of side plates are movably inserted through the guide openings on both sides of the carrier plate. A servo motor is fixedly installed on the outer wall of one set of side plates. A rotating rod is fixedly installed on the inner side of the transmission shaft of the servo motor, and the rotating rod rotates with the other set of side plates through a bearing.

[0007] A traction roller is fixedly installed on the outside of the rotating rod, and there are three sets of traction rollers. A rubber layer is fixedly installed on the outside of the traction roller, and baffles are fixedly installed on both sides of the traction roller.

[0008] A straightening cylinder is fixedly installed on the side of the carrier plate near the traction roller, and a wire hole is opened inside the straightening cylinder;

[0009] A limit switch is fixedly installed on the rear side of the carrier plate, and the signal output terminal of the limit switch is connected to the signal input terminal of the servo motor.

[0010] Guide rods are movably inserted through both sides of the base plate and are fixedly connected to the carrier plate. They can be used in conjunction with three sets of traction rollers, limit switches, and straightening cylinders. During the use of the fixed structure, the wire harness is passed through the straightening cylinder and pressed under the traction rollers. Then, the limit switch is pressed, and the servo motor drives the rotating rod to rotate a certain number of times and stop. The rotating rod, together with the traction rollers and the rubber layer, drives the wire harness to move and supply it to the cutting mechanism for cutting. The setting of the straightening cylinder and the limit switch allows the wire harness to be driven and pulled at a fixed length, which is more efficient and accurate than manual labor. At the same time, the traction and cutting of three sets of wire harnesses can be completed simultaneously, resulting in more ideal efficiency.

[0011] As an optional solution to the technical solution of this application, a drive motor is fixedly installed in the middle of the lower surface of the base plate, and a screw is fixedly installed on the top of the drive motor's transmission shaft. The top of the screw is screwed to a threaded cylinder through an external thread, and the top of the threaded cylinder is fixedly connected to the carrier plate. The screw and threaded cylinder can be used together to drive the screw to rotate. Due to the setting of the threaded cylinder, the base plate can be moved up, increasing the distance between the traction roller and the carrier plate, allowing personnel to insert new wire harnesses. The adjustable design supports batch replacement of wire harnesses and avoids the excessive time spent inserting multiple sets of wire harnesses.

[0012] As an optional solution to the technical solution of this application, support rods are fixedly installed at the four corners of the bottom of the carrier plate, and positioning blocks are fixedly installed at the bottom of the support rods. The positioning bolts can be moved through the positioning blocks of the support rods and screwed into the pre-set threaded structure on the support, so as to realize the detachable and stable positioning of the device.

[0013] As an optional solution to the technical solution of this application, the traction roller is provided with a cutting area on the side facing away from the straightening cylinder, and the cutting area is set on the carrier plate. The cutting area can be used to warn operators and improve the safety factor.

[0014] As an optional solution to the technical solution of this application, an indicator plate is fixedly installed on the side of the carrier plate near the limit switch, and the indicator plate is fixed by welding. The indicator plate can be used to introduce and promote the product, as well as to provide instructions for use and process descriptions.

A base plate 4 is placed at the bottom of the carrier plate 1, and side plates 2 are fixedly installed on both sides of the base plate 4. Both sets of side plates 2 are movably inserted into pre-set guide openings 14 on both sides of the carrier plate 1. A servo motor 21 is fixedly installed on the outer wall of one set of side plates 2. A rotating rod 22 is fixedly installed on the inner side of the drive shaft of the servo motor 21, and the rotating rod 22 rotates with the other set of side plates 2 through a bearing 23. Traction rollers 3 are fixedly installed on the outer side of the rotating rod 22, and there are three sets of traction rollers 3. The system includes a rubber layer 31 and baffles 32 fixedly installed on both sides of the traction roller 3. A straightening cylinder 13 is fixedly installed on the side of the carrier plate 1 near the traction roller 3, and a wire hole 15 is opened inside the straightening cylinder 13. A cutting area 12 is provided on the side of the traction roller 3 facing away from the straightening cylinder 13, and the cutting area 12 is set on the carrier plate 1. The cutting area 12 can be used to warn operators and improve the safety factor. A limit switch 11 is fixedly installed on the rear side of the carrier plate 1, and the signal output terminal of the limit switch 11 is connected to the signal input terminal of the servo motor 21. An indicator sign is fixedly installed on the side of the carrier plate 1 near the limit switch 11, and the indicator sign is fixed by welding. The indicator sign can be used to introduce and promote the product, and also to provide instructions for use and process introduction. Guide rods 41 are movably inserted through both sides of the bottom plate 4, and the guide rods 41 are fixedly connected to the carrier plate 1.

[0025] In this technical solution, components such as three sets of traction rollers 3, limit switches 11, and straightening cylinders 13 can be used together. During the use of the fixed structure, the wire harness can be passed through the straightening cylinder 13 and pressed under the traction rollers 3. Then, the limit switch 11 is pressed, and the servo motor 21 can drive the rotating rod 22 to rotate a number of times and stop. The rotating rod 22, together with the traction rollers 3 and the rubber layer 31, drives the wire harness to move and supply the cutting mechanism for cutting. The setting of the straightening cylinder 13 and the limit switch 11 can enable the wire harness to be driven at a fixed length, which is more efficient and accurate than manual labor. At the same time, the traction and cutting of three sets of wire harnesses can be completed simultaneously, resulting in more ideal efficiency.

The top of the screw 51 is screwed to the threaded cylinder 52 through an external thread, and the top of the threaded cylinder 52 is fixedly connected to the carrier plate 1.

[0027] In this technical solution, components such as screw 51 and threaded cylinder 52 can be used together. The screw 51 can be driven to rotate by the drive motor 5. Due to the setting of the threaded cylinder 52, the base plate 4 can be moved upward, so that the distance between the traction roller 3 and the carrier plate 1 increases, allowing personnel to put in new wire harnesses. The adjustable design supports batch replacement of wire harnesses and avoids the excessive time spent on putting in multiple sets of wire harnesses.

[0028] Working principle: It should be noted that this utility model is a wire harness cutting and fixing structure. All components are general standard parts or parts known to those skilled in the art. Its structure and principle can be learned by those skilled in the art through technical manuals or conventional test methods.

[0029] When using a wire harness cutting fixing structure, the fixing structure is placed in the wire harness cutting area, and then the fixing structure is placed under the external cutting mechanism, and the cutting area 12 is directly under the cutting blade. During this period, the wire harness cutting operation can be carried out in conjunction with the fixing structure.

[0030] By setting up three sets of traction rollers 3, limit switches 11, and straightening cylinders 13, during the use of the fixed structure, the wire harness can be passed through the straightening cylinder 13 and pressed under the traction rollers 3. Then, by pressing the limit switch 11, the servo motor 21 can drive the rotating rod 22 to rotate a number of times and stop. The rotating rod 22, together with the traction rollers 3 and the rubber layer 31, drives the wire harness to move and supply it for cutting by the cutting mechanism. The setting of the straightening cylinder 13 and the limit switch 11 can enable the wire harness to be driven at a fixed length, which is more efficient and accurate than manual labor. At the same time, the traction and cutting of three sets of wire harnesses can be completed simultaneously, which is more efficient. By setting up a screw 51 and a threaded cylinder 52, the drive motor 5 can drive the screw 51 to rotate. Due to the setting of the threaded cylinder 52, the base plate 4 can be moved upward, which increases the distance between the traction rollers 3 and the carrier plate 1, allowing personnel to put in new wire harnesses. The adjustable design supports batch replacement of wire harnesses and avoids the excessive time spent putting in multiple sets of wire harnesses.
