Harness presser machine fixing mechanism

Abstract

This utility model discloses a wire harness crimping machine fixing mechanism, including a base, on which a first conveying mechanism for conveying the wire harness to be crimped is installed. A gantry frame is connected to the base, and an electric push rod is installed on the top of the gantry frame. A toothed movable rod is connected to the electric push rod, and a clamping structure for pressing and limiting the wire harness is connected to the lower end of the toothed movable rod. A linkage structure connected to the toothed movable rod is installed on the side of the gantry frame. This wire harness crimping machine fixing mechanism, through the cooperation of a T-shaped pressure rod and a pressure spring, can stably limit and fix the wire harness. The counterforce of the pressure spring acts on the T-shaped pressure rod, causing the T-shaped pressure rod to press tightly onto the wire harness, ensuring that the wire harness will not shift during crimping, thereby ensuring that the terminals can be accurately installed at the ends of the wire harness. Simultaneously, by adjusting the position of the threaded ring, the pressure on the wire harness can be flexibly changed, avoiding damage to the wire harness sheath due to excessive pressure and effectively protecting the integrity of the wire harness.

Description

Technical Field

[0001] This utility model relates to the technical field of wire harness processing equipment, specifically a wire harness pressing machine fixing mechanism. Background Technology

[0002] In modern electronics, electrical, and automotive manufacturing industries, wire harness processing and assembly are crucial processes. As a vital carrier connecting various electrical components, the quality and reliability of wire harnesses directly impact the performance and safety of the entire equipment. Wire harness crimping machines, a common type of wire harness processing equipment, are widely used in the process of installing terminals onto wire harnesses. However, in practice, to ensure that terminals are stably and accurately fixed to the ends of the wire harness, a fixing mechanism is often required to limit and secure the wire harness.

[0003] Because wire harnesses are easily displaced by external forces during processing, this can lead to loose connections and poor contact between terminals and the wire harness, thus affecting the normal operation of the entire electrical system. Traditional wire harness fixing methods have many problems. For example, some simple manual fixing methods are not only inefficient but also fail to guarantee the accuracy and consistency of each crimping. In addition, manual fixing is prone to quality variations due to differences in operator skill, making it difficult to meet the requirements of product quality stability in large-scale production.

[0004] Therefore, developing a simple and easy-to-operate fixing mechanism is of great significance for improving the working efficiency and crimping quality of wire harness crimping machines. Utility Model Content

[0005] This utility model addresses the problem that existing technical solutions are too simplistic by providing a wire harness pressing machine fixing mechanism that is significantly different from existing technologies, thus solving the problems mentioned in the background.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a wire harness crimping machine fixing mechanism, including a base, a first conveying mechanism for conveying the wire harness to be crimped is installed on the base, and a gantry frame is connected to the base, and an electric push rod is installed on the top of the gantry frame, a toothed movable rod is connected to the electric push rod, and a clamping structure for clamping and limiting the wire harness is connected to the lower end of the toothed movable rod. A linkage structure connected to the toothed movable rod is installed on the side of the gantry frame, and a second conveying mechanism is connected to the linkage structure. The second conveying mechanism is installed on the base between the first conveying mechanism and the gantry frame, and a crimping mechanism for crimping the wire harness and terminals is installed on the other side of the gantry frame on the base.

[0007] Preferably, the first conveying mechanism consists of a motor and a chain-driven conveying roller for transmission, and a limit switch is installed on the top of the gantry frame, and both the limit switch and the motor are electrically connected to the PLC controller.

[0008] Preferably, the clamping structure includes a T-shaped cylinder, a threaded area, a threaded ring, a pressure spring, and a T-shaped pressure rod. The lower end of the toothed movable rod is connected to the T-shaped cylinder, and the outer wall of the T-shaped cylinder is provided with a threaded area. A threaded ring is threadedly connected to the threaded area. A pressure spring is connected to the bottom of the threaded ring, and the lower end of the pressure spring is connected to the T-shaped pressure rod. The upper end of the T-shaped pressure rod is located inside the T-shaped cylinder.

[0009] Preferably, the T-shaped pressure bar and the T-shaped cylinder form an "I" shaped structure, and the T-shaped pressure bar and the T-shaped cylinder are connected by a snap-fit ​​sliding connection.

[0010] Preferably, the linkage structure includes a first rotating shaft, a first full gear, a transmission chain, a second rotating shaft, a second full gear, and a third full gear. The first rotating shaft is rotatably connected to the side of the gantry frame, and the outer wall of the first rotating shaft is respectively connected to the first full gear and the transmission chain via a sprocket. The transmission chain is connected to the second rotating shaft via a sprocket, and the second rotating shaft is rotatably connected to the side of the gantry frame. The outer wall of the second rotating shaft is connected to the second full gear, and the second full gear is meshed with the third full gear. The third full gear is connected to a conveyor roller shaft of the second conveying mechanism. The second conveying mechanism is composed of several conveyor roller shafts linked by chains, and a conveyor track is provided outside the conveyor roller shafts.

[0011] Preferably, the diameter of the second full gear is larger than that of the first full gear, and the diameter of the first full gear is larger than that of the third full gear.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the fixing mechanism of the wire harness crimping machine realizes precise fixing, efficient conveying and automated control of the wire harness, which significantly improves the production efficiency and crimping quality of the wire harness crimping machine, while effectively avoiding damage to the wire harness during processing.

[0013] First, the T-shaped pressure bar and the pressure spring work together to stably limit and fix the wire harness. The counterforce of the pressure spring acts on the T-shaped pressure bar, pressing it firmly against the wire harness and ensuring that the wire harness will not shift during the crimping process, thus ensuring that the terminals can be accurately installed at the end of the wire harness. At the same time, by adjusting the position of the threaded ring, the pressure on the wire harness can be flexibly changed, avoiding damage to the wire harness sheath due to excessive pressure and effectively protecting the integrity of the wire harness.

[0014] Secondly, this fixed mechanism achieves fully automated control of the entire process of wire harness feeding, crimping, conveying, and subsequent automatic transmission. Through the cooperation of a PLC controller and limit switches, the start and stop of the first conveying mechanism can be precisely controlled, ensuring a smooth transition of the wire harness between each process. After crimping, the linked structure and the second conveying mechanism automatically transport the crimped wire harness to the collection box, simultaneously triggering the start of the first conveying mechanism to transmit the next batch of wire harnesses, greatly improving production efficiency, reducing manual intervention, and lowering labor intensity.

[0015] Furthermore, the fixing mechanism is ingeniously designed, compact in structure, and occupies little space, making it easy to install on existing wire harness pressing machines without requiring large-scale modifications to the equipment. At the same time, it can adapt to wire harnesses of different diameters by adjusting the position of the threaded ring, exhibiting good versatility and applicability, and can meet the processing needs of various specifications of wire harnesses, thereby improving the utilization rate and flexibility of the equipment.

The second conveying mechanism 8 is installed on the base 1 between the first conveying mechanism 2 and the gantry 3, and the other side of the gantry 3 on the base 1 is equipped with a clamping mechanism 9 for clamping the wire harness and terminals.

[0023] The first conveying mechanism 2 consists of a motor and a chain-driven conveying roller for transmission. The top of the gantry 3 is equipped with a limit switch, and both the limit switch and the motor are electrically connected to the PLC controller.

[0024] The clamping structure 6 includes a T-shaped cylinder 601, a threaded area 602, a threaded ring 603, a pressure spring 604, and a T-shaped pressure rod 605. The lower end of the toothed movable rod 5 is connected to the T-shaped cylinder 601, and the outer wall of the T-shaped cylinder 601 is provided with a threaded area 602. A threaded ring 603 is threadedly connected to the threaded area 602. A pressure spring 604 is connected to the bottom of the threaded ring 603, and the lower end of the pressure spring 604 is connected to the T-shaped pressure rod 605. The upper end of the T-shaped pressure rod 605 is located inside the T-shaped cylinder 601.

[0025] The T-shaped pressure bar 605 and the T-shaped cylinder 601 form an "I" shaped structure, and the T-shaped pressure bar 605 and the T-shaped cylinder 601 are connected by a snap-fit ​​sliding connection.

[0026] The linkage structure 7 includes a first rotating shaft 701, a first full gear 702, a transmission chain 703, a second rotating shaft 704, a second full gear 705, and a third full gear 706. The first rotating shaft 701 is rotatably connected to the side of the gantry frame 3. The first full gear 702 is connected to the outer wall of the first rotating shaft 701, and the transmission chain 703 is connected to it via a sprocket. The transmission chain 703 is connected to the second rotating shaft 704 via a sprocket. The second rotating shaft 704 is rotatably connected to the side of the gantry frame 3. The second full gear 705 is connected to the outer wall of the second rotating shaft 704. The second full gear 705 is meshed with the third full gear 706. The third full gear 706 is connected to a conveyor roller shaft of the second conveying mechanism 8. The second conveying mechanism 8 is composed of several conveyor roller shafts linked by chains, and a conveyor track is provided outside the conveyor roller shafts.

[0027] The diameter of the second full gear 705 is larger than that of the first full gear 702, and the diameter of the first full gear 702 is larger than that of the third full gear 706.

[0028] Working principle: According to Figure 1 As shown, the wire harness with the crimped terminal is first placed on the first conveying mechanism 2. As the PLC controller issues a command, the motor drives the first conveying mechanism 2 to transmit the wire harness to the gantry 3 and then into the crimping mechanism 9. At this time, the electric push rod 4 starts and pushes the toothed movable rod 5 down. The T-shaped cylinder 601 disengages from the limit switch on the gantry 3 and transmits a signal to the PLC controller to control the motor of the first conveying mechanism 2 to stop. The wire harness on it will no longer be conveyed. As the toothed movable rod 5 moves down, the toothed block surface on it contacts the inclined surface of the toothed block on the first full gear 702 during the downward movement of the toothed movable rod 5. The toothed block surface on the toothed movable rod 5 is pressed into the toothed movable rod 5 and no meshing occurs. Therefore, the first full gear 702 will not be driven to rotate.

[0029] When the T-shaped pressure bar 605 contacts the wire harness, as the toothed movable rod 5 continues to move downward, the T-shaped pressure bar 605 moves into the T-shaped cylinder 601. Under the limit of the threaded ring 603, the pressure spring 604 is compressed. The counterforce of the pressure spring 604 acts on the T-shaped pressure bar 605, so that the T-shaped pressure bar 605 presses tightly on the wire harness to limit it, while avoiding excessive pressure on the wire harness, which could cause damage to the wire harness skin. In addition, the distance between the threaded ring 603 and the T-shaped pressure bar 605 can be changed by rotating the threaded ring 603 to move it on the threaded area 602, thereby adjusting the pressure of the clamping structure 6 on the wire harness.

[0030] Subsequently, the pressing mechanism 9 compacts the wire harness and terminals. After compaction, the electric push rod 4 drives the toothed movable rod 5 to move upward. During the upward movement of the toothed movable rod 5, its upper tooth block surface meshes with the first full gear 702, driving the first rotating shaft 701 to rotate. The first rotating shaft 701 drives the second rotating shaft 704 to rotate through the sprocket and transmission chain 703. The second rotating shaft 704 drives the third full gear 706 to rotate through the second full gear 705. The rotation of the third full gear 706 drives the conveying roller shaft of the second conveying mechanism 8 connected to it to rotate, so that the second conveying mechanism 8 conveys the compacted wire harness to one side and drops it into the collection box connected to the other end of the second conveying mechanism 8.

[0031] At the same time, the upward movement of the toothed movable rod 5 causes the upper end of the T-shaped cylinder 601 to contact the limit switch on the top inner side of the gantry 3, transmitting a signal to the PLC controller, causing the first conveying mechanism 2 to work again to transmit the next batch of wire harnesses. This is the working principle of the wire harness pressing machine fixing mechanism.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
