Description

Technical Field

[0001] This utility model relates to a positioning fixture for processing automotive foot valve switch wiring harnesses, belonging to the field of wiring harness processing technology. Background Technology

[0002] The automotive foot valve switch wiring harness is a key component connecting the foot valve switch to other electrical system components, primarily used to enable the driver to control certain functions (such as acceleration, braking, and starting) via foot operation. With the increasing electrification of automobiles, the functions of foot valve switches have become increasingly complex, and the design and manufacturing requirements of the wiring harness have become increasingly sophisticated. To ensure the high reliability and stability of the foot valve switch system, the wiring harness needs to possess properties such as high temperature resistance, corrosion resistance, and interference resistance, while also ensuring the accuracy and safety of connectors and electrical connections. Against this backdrop, specialized positioning tooling technology has been developed for the processing and assembly of foot valve switch wiring harnesses to help improve production efficiency and ensure product quality.

[0003] Authorization announcement number (CN110473672B) discloses a wire harness processing device, including a guiding mechanism, a wire stripping mechanism fixed to the guiding mechanism, and a wire twisting mechanism slidably disposed on the guiding mechanism. The guiding mechanism includes a guiding assembly comprising a connecting plate and at least two guide rods evenly distributed and fixed to the connecting plate circumferentially. The wire stripping mechanism includes a feeding assembly, a rotating assembly connected to one end of the feeding assembly and capable of relative rotation, a cutting assembly disposed on the rotating assembly, and an adjusting assembly for controlling the radial movement of the cutting assembly. The feeding assembly is fixed to the guide rods. The wire twisting mechanism includes a receiving disc, multiple centrifugal components evenly distributed circumferentially inside the receiving disc, a driving assembly for driving the receiving disc and the centrifugal components to rotate circumferentially, and a fixing ring disposed around the periphery of the receiving disc. This invention simultaneously possesses wire stripping and twisting functions and has high production efficiency.

[0004] In summary, the wire harness processing device described above lacks a positioning component for the wire harness. Without this component, several problems may arise during wire harness processing. First, the lack of precise positioning may lead to inaccurate placement of wire harness components during assembly, affecting the reliability of electrical connections and increasing the risk of poor contact. Second, due to the absence of fixed points, operators need to manually adjust and align the wire harness, increasing labor intensity and the probability of errors during processing, thus reducing production efficiency.

[0005] To address this, a positioning fixture for machining automotive foot valve switch wiring harnesses is proposed. Utility Model Content

[0006] In view of this, the present invention provides a positioning fixture for processing automotive foot valve switch wiring harnesses to solve or alleviate the technical problems existing in the prior art, and at least provides a beneficial option.

[0007] The technical solution of this utility model is implemented as follows: A positioning fixture for processing automotive foot valve switch wiring harness includes a fixture table. A fixing component is provided on the top of the fixture table. The fixing component includes a U-shaped plate, which is fixedly installed on the top of the fixture table. First threaded rods are threadedly connected to both the left and right sides of the U-shaped plate. A spring housing is fixedly installed on the inner side of the first threaded rod. A fixing rod is movably connected to the inner side of the spring housing. A rigid spring is sleeved on the surface of the fixing rod. A fixing ring is fixedly installed on the surface of the fixing rod.

[0008] More preferably, a clamp is fixedly installed on the inner side of the fixing rod, and a rocker arm is fixedly installed on the outer side of the first threaded rod.

[0009] More preferably, a cleaning component is provided on the top of the tooling table. The cleaning component includes a cabinet, which is fixedly installed on the top of the tooling table. A threaded outer shell is fixedly installed on the inner side of the tooling table and at the bottom of the cabinet. A second threaded rod is movably connected to the inner side of the threaded outer shell through a pivot. A threaded sleeve is slidably connected to the surface of the second threaded rod. A brush is fixedly installed on the top of the threaded sleeve.

[0010] More preferably, a motor is fixedly installed on the right side of the threaded housing, and the output end of the motor is fixedly connected to the second threaded rod.

[0011] More preferably, the cabinet has wire harness inlets and outlets on both the left and right sides, and a fan is fixedly installed on the rear side of the cabinet.

[0012] More preferably, a box is fixedly installed on the rear side of the cabinet, and a water pump is fixedly installed at the bottom of the inner cavity of the box, with the output end of the water pump connected to a water pipe.

[0013] More preferably, the end of the water pipe away from the water pump is connected to a corrugated pipe, the end of the corrugated pipe away from the water pipe is connected to a brush, and a water inlet is provided on the top of the box.

[0014] The present invention has the following advantages due to the adoption of the above technical solution:

[0015] I. This utility model uses a rocker arm to drive a first threaded rod and a spring housing. The first threaded rod moves inward toward the U-shaped plate through the action of the surface thread. The wire harness is fixed by a clamp. At this time, the clamp is pressed, which drives the fixing rod and fixing ring to move inward toward the spring housing. The rigid spring deforms under pressure, reducing the pressure of the clamp on the wire harness, ensuring precise alignment of each component, improving processing accuracy and efficiency, and ensuring the reliability and stability of the electrical connection. At the same time, it avoids damage to the wire harness caused by excessive squeezing during fixing.

[0016] II. This utility model utilizes a motor. The motor's output drives a second threaded rod, which, through its surface threads, moves a threaded sleeve and a brush. The brush cleans dust and dirt from the wire harness surface. Simultaneously, a water pump draws water from the housing and distributes it to the water pipes, corrugated pipes, and brushes, wetting the brushes and preventing contaminants from affecting the quality and reliability of electrical connections. This ensures that key components such as connectors and terminals remain clean, preventing corrosion or poor contact and improving the wire harness's performance and durability.

[0026] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0027] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0028] Example 1

[0029] like Figure 1-5 As shown, this utility model embodiment provides a positioning fixture for processing automotive foot valve switch wiring harnesses, including a fixture table 1. A fixing component 2 is provided on the top of the fixture table 1. The fixing component 2 includes a U-shaped plate 201, which is fixedly installed on the top of the fixture table 1. The left and right sides of the U-shaped plate 201 are threadedly connected to a first threaded rod 207. A spring housing 203 is fixedly installed on the inner side of the first threaded rod 207. A fixing rod 205 is movably connected to the inner side of the spring housing 203. A hard spring 204 is sleeved on the surface of the fixing rod 205. A fixing ring 206 is fixedly installed on the surface of the fixing rod 205.

[0030] By rocking the rocker arm 202, the first threaded rod 207 and the spring housing 203 are driven. The first threaded rod 207 moves inward toward the U-shaped plate 201 through the action of the surface thread. The wire harness is fixed by the clamp 208. At this time, the clamp 208 is pressed and drives the fixing rod 205 and the fixing ring 206 to move inward toward the spring housing 203. The rigid spring 204 is compressed and deforms to reduce the pressure of the clamp 208 on the wire harness, ensuring that each component is accurately aligned, improving processing accuracy and efficiency, and ensuring the reliability and stability of the electrical connection. At the same time, it avoids damage to the wire harness caused by excessive squeezing during fixing.

[0031] Example 2

[0032] like Figure 1-6As shown, in one embodiment, a clamp 208 is fixedly installed on the inner side of the fixing rod 205, a rocker arm 202 is fixedly installed on the outer side of the first threaded rod 207, and a cleaning assembly 3 is provided on the top of the tooling table 1. The cleaning assembly 3 includes a cabinet 301, which is fixedly installed on the top of the tooling table 1. A threaded outer shell 302 is fixedly installed on the inner side of the tooling table 1 and at the bottom of the cabinet 301. A second threaded rod 303 is movably connected to the inner side of the threaded outer shell 302 through a pivot. A threaded sleeve 304 is slidably connected to the surface of the second threaded rod 303. The top of the threaded sleeve 304 is fixedly installed... A brush 305 is installed. A motor 306 is fixedly installed on the right side of the threaded housing 302. The output end of the motor 306 is fixedly connected to the second threaded rod 303. The left and right sides of the cabinet 301 are provided with wire harness inlets and outlets 9. A fan 307 is fixedly installed on the rear side of the cabinet 301. A box 4 is fixedly installed on the rear side of the cabinet 301. A water pump 6 is fixedly installed at the bottom of the inner cavity of the box 4. The output end of the water pump 6 is connected to a water pipe 7. The end of the water pipe 7 away from the water pump 6 is connected to a corrugated pipe 8. The end of the corrugated pipe 8 away from the water pipe 7 is connected to the brush 305. A water inlet 5 is provided on the top of the box 4.

[0033] By starting motor 306, the output end of motor 306 drives the second threaded rod 303 to move. The second threaded rod 303, through the action of its surface threads, drives the threaded sleeve 304 and brush 305 to move. The brush 305 cleans the dust and dirt on the surface of the wire harness. By starting water pump 6, the input end of water pump 6 draws water from the housing 4, and the output end of water pump 6 delivers water to water pipe 7, corrugated pipe 8, and brush 305 to wet brush 305, preventing these contaminants from affecting the quality and reliability of electrical connections. This ensures that key parts such as connectors and terminals are kept clean, preventing corrosion or poor contact, and improving the performance and durability of the wire harness.

[0034] In operation, this invention works as follows: First, the wire harness to be processed is placed in the center of the clamp 208. By shaking the rocker arm 202, the first threaded rod 207 and the spring housing 203 are driven. The first threaded rod 207 moves inward towards the U-shaped plate 201 due to the action of its surface threads. The clamp 208 then fixes the wire harness. At this time, the clamp 208 is under pressure, causing the fixing rod 205 and the fixing ring 206 to move inward towards the spring housing 203. The rigid spring 204 deforms under pressure, reducing the pressure of the clamp 208 on the wire harness, ensuring precise alignment of all components, improving processing accuracy and efficiency, and ensuring the reliability of electrical connections. Stability is ensured while preventing damage to the wire harness caused by excessive compression during fixing. By starting the motor 306, its output drives the second threaded rod 303 to move. The second threaded rod 303, through its surface threads, moves the threaded sleeve 304 and the brush 305. The brush 305 cleans dust and dirt from the wire harness surface. Simultaneously, starting the water pump 6 draws water from the housing 4 through its input and delivers it to the water pipe 7, corrugated pipe 8, and brush 305 through its output, wetting the brush 305 and preventing contaminants from affecting the quality and reliability of electrical connections. This ensures that critical parts such as connectors and terminals remain clean, preventing corrosion or poor contact and improving the performance and durability of the wire harness.

[0035] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
