Description

Technical Field

[0001] The present invention relates to the technical field of steering gear assembly, and specifically to an automotive steering gear wire harness assembly device. Background Art

[0002] An automotive steering gear, also known as a steering machine or a steering gear, is the most important component in an automotive steering system. Its function is to increase the force transmitted from the steering wheel to the steering transmission mechanism and change the direction of force transmission.

[0003] More specifically, the function of the steering gear is to increase the force transmitted from the steering wheel to the steering transmission mechanism and change the direction of force transmission. The steering device is a device that controls the driving direction of an automobile, and it must meet the following requirements: safe and reliable operation, light and flexible operation, appropriate steering force, smooth rotation performance, and little impact transmitted from the road.

[0004] A wire harness is generally a cable assembly composed of wires, connectors, protective sleeves, etc., and is used to transmit electric power and signals. Its functions are to connect a torque sensor: to detect the steering force of the steering wheel and transmit it to the ECU for calculating the assistance requirement, and at the same time to connect a steering angle sensor: to monitor the steering angle of the steering wheel and is used in systems such as ESP and lane keeping. There are also other wire harnesses for powering the sensors: usually a 5V regulated power supply, and for powering the assistance motor: the ECU controls the motor to output the assistance torque through the wire harness.

[0005] As is well known, in order to meet the working requirements of the steering gear, it is generally necessary to assemble the wire harness inside the steering gear.

[0006] In the prior art, for example, in a Chinese patent with the application publication number CN111366100A and the name of an automatic assembly line for a steering gear assembly, the above patent discloses an automatic assembly line for an automotive steering gear assembly, including a mounting seat inspection machine, an end cover assembly machine, a terminal assembly machine, a characteristic inspection machine, and a coating machine. The mounting seat inspection machine inspects the height of the connector on the mounting seat, the height of the insertion piece, the inner hole of the connector, and the size of the through hole; the end cover assembly machine mounts the end cover on the mounting seat; the terminal assembly machine connects the connection terminals to the mounting seat so that the connection terminals are correspondingly connected to the connector.

[0007] For another example, there is a Chinese patent with the authorization announcement number CN219565221 and the name of an automotive power steering gear. The above-mentioned patent discloses a Chinese patent for an automotive power steering gear, which is provided with a steering gear body. A plurality of mounting holes are provided on the steering gear body. The mounting holes are divided into a frame mounting hole and a wire harness mounting hole. A wire harness mounting hole for wire harness installation is provided at the middle position of the steering gear body. A frame mounting hole for frame mounting is provided on one side of the wire harness mounting hole. A bearing hole is provided between the frame mounting hole and the wire harness mounting hole. A wire harness mounting hole is provided on the power steering gear. The wire harness can be well installed by using the wire harness mounting hole, which is convenient for subsequent wire harness installation during vehicle assembly. At the same time, a frame mounting hole is provided on the power steering gear, which can facilitate the assembly of the power steering gear and the frame, making the assembly of the power steering gear more convenient and the assembly effect better, meeting the work requirements of efficient assembly.

[0008] In the prior art such as the above-mentioned patent, the requirement for wire harness installation inside the steering gear can be met to a certain extent. As is well known, in order to further improve the stability of the wire harness body during installation, a protective sleeve made of an elastic material is generally selected to be provided outside the wire harness, and an installation groove adapted to the protective sleeve is provided on the steering gear. More specifically, in order to further improve the stability of the wire harness body during installation, the protective sleeve and the installation groove are set in an interference fit manner. Due to the special structure of the steering gear, the protective sleeve is in an inclined state when installed inside the installation groove. Therefore, when the protective sleeve needs to be snapped into the installation groove, the operation process for the operator to install the protective sleeve into the installation groove using tools is extremely inconvenient, and there are certain deficiencies.

Detailed implementation manners

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0037] Please refer to Figures 1 - 13 , the present invention provides a technical solution: an automotive steering gear wire harness assembly device, including a frame 1 and a bearing plate 2 mounted on the frame 1. A steering gear body 4 is mounted on the frame 1 through a positioning frame 3. An installation groove 15 is provided on the steering gear body 4, and a wire harness body 13 is arranged inside the installation groove 15. A protective sleeve 14 is arranged outside the wire harness body 13. A first mounting plate 5 is vertically slidably connected to the frame 1, and a first cylinder 6 for driving the first mounting plate 5 to slide vertically is arranged on the frame 1. A closing and fastening mechanism 12 is arranged on the first mounting plate 5, and the closing and fastening mechanism 12 drives the protective sleeve 14 to be clamped with the installation groove 15.

[0038] Specifically, the automotive steering gear wire harness assembly device includes a frame 1 and a carrier plate 2 mounted on the frame 1. The steering gear body 4 is mounted on the frame 1 through a positioning frame 3. The steering gear body 4 is a prior art, and its structure and working principle are not elaborated here. An installation groove 15 is provided on the steering gear body 4, and a wire harness body 13 is arranged inside the installation groove 15. A protective sleeve 14 is arranged outside the wire harness body 13. Therefore, when the protective sleeve 14 is snapped into the installation groove 15, it can protect the wire harness body 13 and thus improve the service life of the wire harness body 13. A first mounting plate 5 is vertically slidably connected to the frame 1, and a first cylinder 6 for driving the first mounting plate 5 to slide vertically is arranged on the frame 1. Specifically, the first cylinder 6 can drive the first mounting plate 5 to slide vertically so that the first mounting plate 5 can move to a predetermined position, facilitating the limit snap connection of the position of the protective sleeve 14 and making the installation of the protective sleeve 14 more convenient. Specifically, a closing and fastening mechanism 12 is arranged on the first mounting plate 5, and the closing and fastening mechanism 12 drives the protective sleeve 14 to be snap-connected with the installation groove 15. During use, when the installation sleeve needs to be fixed inside the steering gear body 4, first, the protective sleeve 14 is installed inside the installation groove 15 inside the steering gear body 4, and then the first cylinder 6 is started. The first cylinder 6 can drive the first mounting plate 5 to slide vertically so that the first mounting plate 5 can move to a predetermined position. Then, the closing and fastening mechanism 12 is used to drive the protective sleeve 14 to be snap-connected inside the installation groove 15, so that the protective sleeve 14 is press-fitted and snap-connected inside the installation groove 15 to fix the protective sleeve 14. During this process, after using the first cylinder 6 to control the closing and fastening mechanism 12 to adjust the state, the protective sleeve 14 is fixed through the closing and fastening mechanism 12. While improving the installation stability of the protective sleeve 14, it can also improve the installation efficiency of the protective sleeve 14 to meet the work requirements.

[0039] In the embodiment provided by the present invention, a second mounting plate 7 is further mounted on the first mounting plate 5. A third mounting plate 9 is slidably connected to the second mounting plate 7 through a second cylinder 10. The closing and fastening mechanism 12 is arranged on the third mounting plate 9. At this time, the second cylinder 10 can be used to drive the third mounting plate 9 to slide, and thus the state of the closing and fastening mechanism 12 can be adjusted, enabling the closing and fastening mechanism 12 to move in a more accurate state to clamp the installation sleeve tightly inside the installation groove 15, with better use effects.

[0040] In the embodiments provided by the present invention, the closing and fastening mechanism 12 includes a second clamping plate 122 slidably connected to the third mounting plate 9, and a first clamping plate 121 is further provided on the third mounting plate 9. A third air cylinder 123 for driving the second clamping plate 122 and the first clamping plate 121 to approach each other is provided on the third mounting plate 9. Specifically, during use, the third air cylinder 123 drives the second clamping plate 122 to move towards the first clamping plate 121. At this time, the first clamping plate 121 presses against the top of the protective sleeve 14. At this moment, the second clamping plate 122 clamps the outer wall of the protective sleeve 14. The third air cylinder 123 drives the second clamping plate 122 to move towards the first clamping plate 121, so that the protective sleeve 14 deforms, driving the protective sleeve 14 to be clamped inside the mounting groove 15, and driving the protective sleeve 14 to further press against the mounting groove 15, so that the protective sleeve 14 and the mounting groove 15 are in interference fit, increasing the friction force, and further improving the stability of the protective sleeve 14 during installation.

[0041] In the embodiments provided by the present invention, a pressing block 125 is fixedly connected to the second clamping plate 122, and the pressing block 125 abuts against the outside of the protective sleeve 14. More specifically, a convex ring is provided on the outside of the protective sleeve 14, and the pressing block 125 is adapted to the shape of the convex ring. When the second clamping plate 122 drives upward, the pressing block 125 will be pressed to drive the convex ring upward, better driving the protective sleeve 14 to deform, and further improving the stability of the protective sleeve 14 during installation, with excellent effects.

[0042] In the embodiments provided by the present invention, a prevention unit is further provided on the second clamping plate 122. The prevention unit can prevent the pressing block 125 from not contacting the convex ring on the outside of the protective sleeve 14 during the first movement stroke. Then, during the subsequent upward movement stroke of the second clamping plate 122, the prevention unit can replace the pressing block 125 to contact the convex ring on the outside of the protective sleeve 14, and then continue to drive the protective sleeve 14 upward to clamp the protective sleeve 14 inside the mounting groove 15. At this time, the working efficiency of the assembly equipment can be further improved. If the pressing block 125 fails to contact the protective sleeve 14 in time due to special reasons, instead of driving the second clamping plate 122 to reset by the third air cylinder 123, the second clamping plate 122 is continuously driven to approach the first clamping plate 121, and the prevention unit is used to drive the protective sleeve 14 to fix the protective sleeve 14, which can improve the working efficiency and has better use effects.

[0043] Among them, the prevention unit includes a prevention block 126 slidably connected to the second clamping plate 122. A positioning groove is formed in the second clamping plate 122. The prevention block 126 is slidably connected to the second clamping plate 122 through the positioning groove. A limiting block 127 is provided between the second clamping plate 122 and the positioning groove. The limiting block 127 is slidably connected to the positioning groove, and a positioning spring 128 is provided between the limiting block 127 and the positioning groove. The elastic force of the positioning spring 128 drives the prevention block 126 away from the positioning groove. Specifically, under the action of the positioning spring 128, the prevention block 126 is driven away from the positioning groove. At this moment, during the working process, when the third cylinder 123 drives the second clamping plate 122 to move closer to the first clamping plate 121, the pressing block 125 is adapted to the convex ring on the protective sleeve 14. When the second clamping plate 122 drives upward, the pressing block 125 will be pressed to drive the convex ring upward, better driving the protective sleeve 14 to deform. During this working process, when the pressing block 125 abuts against the convex ring on the protective sleeve 14, at this time, the prevention block 126 abuts against the protective sleeve 14 under the elastic action of the positioning spring 128, which can further improve the stability of the protective sleeve 14 during installation, and the effect is excellent. If the pressing block 125 fails to contact the protective sleeve 14 in time due to special reasons, at this moment, when the second clamping plate 122 continues to move upward, it will drive the prevention block 126 to move upward together. At this time, the prevention block 126 will contact the convex ring on the protective sleeve 14 and drive the protective sleeve 14 to move upward, clamping the protective sleeve 14 inside the installation groove 15. At this moment, the function of the prevention block 126 can be maximally exerted, and the use effect is excellent, which is suitable for wide promotion and use.

[0044] In the embodiment provided by the present invention, a limiting member 11 is provided between the second clamping plate 122 and the third mounting plate 9 to improve the stability of the second clamping plate 122 during sliding; the limiting member 11 includes a limiting rod 111 fixedly connected to the second clamping plate 122. The limiting rod 111 is slidably connected to the third mounting plate 9, and a return spring 112 is provided between the limiting rod 111 and the third mounting plate 9, and the use effect is better.

[0045] In the embodiment provided by the present invention, a servo motor 8 is provided on the second mounting plate 7. The drive shaft of the servo motor 8 is connected to the third mounting plate 9 through a reducer, and is used to drive the third mounting plate 9 to move. Therefore, during the use process, the state of the closing and fastening mechanism 12 can be further adjusted according to the working needs, and the state of the protective sleeve 14 can be better fixed, and the effect is better.

[0046] In the embodiment provided by the present invention, an avoidance groove 124 is formed in the second clamping plate 122. The avoidance groove 124 is adapted to the protective sleeve 14 to meet the fixing requirements of the protective sleeve 14.

[0047] In the embodiments provided by the present invention, the positioning frame 3 is of a telescopic type, and a power unit for driving the steering gear body 4 to move upward is provided at the bottom of the frame 1, which can adjust the state of the steering gear body 4 according to the working needs, making it more convenient to install the wire harness body 13 and achieving better use effects.
