Description

Technical Field

[0001] This utility model belongs to the field of wire harness assembly technology, and relates to a wire harness sleeve hole enlarging machine, specifically a wire harness sleeve hole enlarging machine and hole enlarging system. Background Technology

[0002] A wire harness sleeve enlarging machine is a device used to enlarge the holes in the sleeves of wire harnesses, making it easier to insert the wire harnesses inside.

[0003] Chinese Patent Publication No. CN202068128U discloses a pneumatic wire harness sleeve reaming machine, including an air pump and an air pump head. The key feature is that an air pump mounting plate is installed at the front end of the air pump, and a vertical clamping plate coaxial with the air pump is installed at the front of the mounting plate. The air pump head reciprocates within the clamping plate. A linkage crank is coaxially hinged to the pump head within the clamping plate. Each head of the linkage crank is fixed with a reaming needle in the same direction. The linkage crank expands and contracts in a concentric circle under the push and pull of the air pump head. This reaming machine uses a pneumatic pump as its power source, providing rapid and reliable operation. The linkage crank mounted on the air pump head, which radially expands the sleeve, effectively reduces labor intensity and improves production efficiency.

[0004] In the aforementioned patent, in order to adjust the opening of the linkage crank, a spiral disk is installed on the air pump mounting plate coaxially with the air pump in a threaded engagement manner. The spiral disk can control the stroke of the linkage crank in a straight line through the stroke change generated by the thread engagement, that is, control the stroke length of the linkage crank, thereby controlling the opening diameter of the linkage crank to adapt to rubber sleeves with different expansion.

[0005] However, in actual use, due to vibration or other factors, the position of the spiral disk may shift, making it impossible to accurately control the opening of the linkage crank, which affects the subsequent assembly of the wiring harness.

[0006] Therefore, it is essential to provide a wire harness sleeve reaming machine that provides accurate and reliable hole enlargement and facilitates subsequent wire harness assembly. Summary of the Invention

[0007] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a wire harness sleeve hole enlarging machine and hole enlarging system that is accurate and reliable in hole enlarging, facilitates subsequent wire harness assembly, and is easy to implement.

[0008] The technical problem solved by this utility model is achieved through the following technical solution:

[0009] A wire harness sleeve reaming machine includes a reaming machine body, characterized in that it further includes a telescopic limiting mechanism, the telescopic limiting mechanism including a guide block, a positioning pin, a pull pin, a guide post, and a spring. A guide block is installed between two clamping plates of the reaming machine body. A pull pin is inserted through the middle of the guide block. A positioning pin is connected to the bottom of the pull pin. Guide posts extending from the upper part of the guide block are fixedly installed on the positioning pins at both ends of the pull pin. A spring is fitted between the guide block and the positioning pin on each guide post. The positioning pin limits the external thread positioning sleeve by meshing with a gear plate.

[0010] Furthermore, the reaming machine body includes a cylinder, a cylinder mounting plate, clamping plates, an internal thread positioning ring, an external thread positioning sleeve, a linkage crank, and reaming pins. A cylinder mounting plate is installed at the front end of the cylinder, and two vertically arranged clamping plates are installed at the front end of the cylinder mounting plate. An internal thread positioning ring is installed on the cylinder mounting plate within the two clamping plates. The internal thread positioning ring is coaxially arranged with the cylinder pump head. An external thread positioning sleeve is threadedly connected to the front end of the internal thread positioning ring. The external thread positioning sleeve has a structure in which a gear plate is coaxially arranged on the outer wall of the front end of the sleeve body. The cylinder pump head extends and retracts within the external thread positioning sleeve. An intermediate machine head is connected to the front end of the cylinder pump head. A linkage crank is hinged at the front end of the intermediate machine head and is arranged between the two clamping plates. Reaming pins are fixedly installed in the same direction at the head of the linkage crank. The linkage crank achieves concentric expansion and contraction under the extension and retraction of the cylinder pump head.

[0011] Moreover, the positioning pin head is an inverted convex structure, including a horizontal part and a vertical part protruding below the horizontal part. The pull pin and guide post are both fixedly connected to the horizontal part. The bottom end of the vertical part is a round head structure, which is adapted to the tooth groove on the gear plate.

[0012] Furthermore, the aforementioned expanding needle has a structure in which reinforcing ribs are provided on the inner side of the needle body along its length.

An electric linear slide is mounted on the other end of the mounting base, and the movable wire harness sleeve reaming machine is slidably mounted on the electric linear slide. The fixed wire harness sleeve reaming machine and the movable wire harness sleeve reaming machine are arranged opposite to each other.

[0014] Furthermore, a rubber head is fitted onto the head of each of the aforementioned reaming needles.

[0015] The advantages and positive effects of this utility model are:

[0016] 1. This wire harness sleeve reaming machine, by setting a telescopic limit mechanism on the existing wire harness sleeve reaming machine, reliably limits the telescopic amount of the cylinder pump head, avoiding the problem of unstable connection between the internal thread positioning ring and the external thread positioning sleeve affecting the reaming accuracy, and ensuring the smooth installation of the wire harness.

[0017] 2. This wire harness sleeve reaming machine has reinforcing ribs on the inside of the reaming pin. These ribs effectively enhance the strength of the reaming pin, preventing deformation caused by long-term manual pulling during material feeding. They also prevent accidental injury to workers due to pin breakage.

[0018] 3. This wire harness sleeve expanding machine and expanding system, by setting rubber heads on the heads of each expanding needle, can avoid the problem of the sharp tip injuring the staff when manually putting on the sleeve; on the other hand, when two expanding needles are close to each other on the expanding system, it can avoid hard contact and extend their service life.

[0019] 4. This wire harness sleeve enlargement system can enlarge the holes of longer wire harness sleeves, achieving stable and efficient enlargement of longer wire harness sleeves.

[0020] 5. This utility model is scientifically and rationally designed, and has the advantages of high hole expansion accuracy, convenient subsequent wire harness assembly, safety and reliability, meeting the hole expansion needs of wire harness sleeves of different lengths, and easy implementation. It is a wire harness sleeve hole expansion machine and hole expansion system with high innovation. Attached Figure Description

Detailed Implementation

[0026] The embodiments of this utility model will be further described in detail below with reference to the accompanying drawings:

[0027] This utility model provides two types of hole-expanding machines for wire harness sleeves: one suitable for expanding holes in shorter wire harness sleeves, and the other suitable for expanding holes in longer wire harness sleeves.

[0028] Example 1: A hole-reaming machine suitable for expanding holes in short wire harness sleeves.

[0029] A wire harness sleeve reaming machine includes a reaming machine body, which comprises a cylinder 8, a cylinder mounting plate, a clamping plate 3, an internal thread positioning ring 7, an external thread positioning sleeve, a linkage crank 1, and reaming pins 2. A cylinder mounting plate is installed at the front end of the cylinder, and two vertically arranged clamping plates are installed at the front end of the cylinder mounting plate. An internal thread positioning ring, mounted on the cylinder mounting plate, is disposed within the two clamping plates. The internal thread positioning ring is coaxially arranged with the cylinder pump head. An external thread positioning sleeve is threadedly connected to the front end of the internal thread positioning ring. The external thread positioning sleeve has a structure in which a gear plate 6 is coaxially arranged on the outer wall of the front end of the sleeve body. The cylinder pump head extends and retracts within the external thread positioning sleeve. An intermediate machine head 5 is connected to the front end of the cylinder pump head, and a linkage crank, disposed between the two clamping plates, is hinged at the front end of the intermediate machine head. Reaming pins are fixedly mounted in the same direction at the head of the linkage crank. The linkage crank achieves concentric expansion and contraction under the extension and retraction of the cylinder pump head.

[0030] Its innovation lies in the fact that it also includes a telescopic limiting mechanism 4, which includes a guide block 9, a positioning pin head 11, a pull pin 10, a guide post 12, and a spring 13. A guide block is installed between the two clamping plates of the reamer body. A pull pin is inserted through the middle of the guide block. A positioning pin head is connected to the bottom of the pull pin. Guide posts extending from the upper part of the guide block are fixed on the positioning pin heads at both ends of the pull pin. A spring is fitted between the guide block and the positioning pin head on each guide post. The positioning pin head achieves the limiting of the external thread positioning sleeve by meshing with the gear plate.

[0031] The locating pin head is an inverted convex structure, including a horizontal part and a vertical part protruding below the horizontal part. The pull pin and guide post are both fixedly connected to the horizontal part. The bottom end of the vertical part has a rounded head structure, which is adapted to the tooth groove on the gear plate. The length of the locating pin head is adapted to the lateral movement length of the gear plate.

[0032] During operation, the gear disc is rotated according to the hole enlargement requirements, and the position of the gear disc limits the forward and backward extension space of the middle machine head. To ensure the reliability of the gear disc's position, this invention designs a telescopic limiting mechanism, which involves manually pulling a pin to insert the positioning pin head into the tooth groove of the gear disc, thereby limiting the gear disc and preventing problems such as disengagement that could cause it to rotate during operation.

[0033] After the wire harness passes through the wire harness sleeve, both ends of the wire harness need to be manually fixed, and the wire harness sleeve needs to be pulled off the reamer pin with force. Long-term dragging during feeding can easily cause the reamer pin to deform or even break. Therefore, in order to enhance the strength of the reamer pin, the reamer pin has a structure with reinforcing ribs set along its length on the inner side of the pin body.

[0034] Example 2: A hole-reaming machine suitable for expanding holes in long wire harness sleeves.

[0035] An innovative wire harness sleeve reaming system includes a mounting base 16, a mounting seat 15, an electric linear slide 17, a fixed wire harness sleeve reaming machine 14, and a movable wire harness sleeve reaming machine 18. The mounting seat is fixedly mounted at one end of the mounting base, and the fixed wire harness sleeve reaming machine is fixedly mounted on the mounting seat. The electric linear slide is mounted at the other end of the mounting base, and the movable wire harness sleeve reaming machine is slidably mounted on the electric linear slide. The fixed and movable wire harness sleeve reaming machines are arranged opposite to each other. The fixed and movable wire harness sleeve reaming machines have the same structure as the wire harness sleeve reaming machine in Embodiment 1.

[0036] In use, the mounting base is fixedly installed on the operating table. The position of the movable wire harness sleeve expander on the electric linear slide is adjusted according to the length of the wire harness sleeve to be assembled. After adjustment, both ends of the wire harness sleeve are respectively fitted onto the expanding pins of the fixed and movable wire harness sleeve expanders. Then, the movable wire harness sleeve expander is driven to move, causing the expanding pins on both machines to contact each other. Subsequently, the cylinders on both machines operate, working together to expand the wire harness sleeve. Finally, the wire is threaded and the material is unloaded.

[0037] To prevent the reaming pins on the fixed wire harness sleeve reaming machine from making hard contact with the reaming pins on the moving wire harness sleeve reaming machine, a rubber head is fitted onto the head of each of the reaming pins.

[0038] Although embodiments and drawings of the present invention have been disclosed for illustrative purposes, those skilled in the art will understand that various substitutions, variations and modifications are possible without departing from the spirit and scope of the present invention and the appended claims. Therefore, the scope of the present invention is not limited to the contents disclosed in the embodiments and drawings.
