Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0031] like Figure 1-2 The image shows an automotive wiring harness sheath clamping and fixing device provided in this embodiment, including a pressure plate 1, a lifting device 2, a sheath positioning device 3, and a pressure regulating device 4;

[0032] The wire harness sheath 8 to be processed is installed on the sheath positioning device 3. The lifting device 2 is located on one side of the sheath positioning device 3.

The pressure adjusting device 4 is connected to the lifting device 2. The pressure adjusting device 4 can adjust the downward pressure of the lifting device 2 and the pressure plate 1.

[0033] This utility model discloses an automotive wiring harness sheath pressing and fixing device. A lifting device drives the pressure plate to descend, thereby pressing and fitting the wiring harness sheath to be processed into the fastener within the sheath positioning device. A pressure regulating device adjusts the required downward pressure of the pressure plate, thus ensuring the bonding effect between the wiring harness sheath and the fastener, guaranteeing processing quality, and improving processing efficiency.

[0034] In a specific embodiment, the lifting device 2 includes a support plate 21 and a cylinder 22. The cylinder 22 is vertically mounted on the support plate 21, and the piston end of the cylinder 22 is provided with the pressure plate 1. The pressure regulating device 4 is connected to the cylinder 22 through a pipeline. The pressure regulating device 4 can adjust the air intake or exhaust of the cylinder 22 to drive the cylinder 22 to extend, hold, or retract, thereby driving the pressure plate 1 to complete the pressing process of the wire harness sheath 8 and the fastener to be processed.

When it is necessary to adjust the downward pressure of the cylinder 22, a basic output pressure is first set by the pressure regulator, and then the pneumatic pressure divider valve is used to further distribute and fine-tune this pressure to meet the precise pressure requirements of the cylinder 22 in different working environments, ensuring the bonding effect between the wire harness sheath and the hook and loop. The adjustment of the downward pressure of the cylinder by the pneumatic pressure divider valve is prior art, and its more specific principle will not be elaborated here.

In this embodiment, the pressure plate is arranged horizontally, and the cross-sectional area of ​​the pressure plate 1 is larger than the cross-sectional area of ​​the sheath mounting groove to ensure that the pressure plate The area of ​​1 ensures the force-bearing area between the hook and the wire harness sheath, thus ensuring the bonding effect between the two; the positioning block 31 facilitates the positioning of the wire harness sheath to be processed and ensures the stability of the position of the wire harness sheath to be processed during the pressing process; the photoelectric sensor 32 is a through-beam photoelectric sensor 32 respectively set on both sides of the bottom of the sheath mounting groove 311. When the sheath is in place, it blocks the light beam, thereby detecting whether the wire harness sheath 8 to be processed is installed in the sheath mounting groove, avoiding poor bonding between the wire harness sheath and the hook due to improper installation of the sheath.

[0039] In a specific embodiment, the device further includes a housing 6 and a base plate 7. The housing 6, the lifting device 2, and the sheath positioning device 3 are mounted on the base plate 7. The housing 6 is located outside the lifting device 2 and the sheath positioning device 3. The control panel 5 and the pressure regulator 41 are mounted on the housing. The pneumatic pressure dividing valve 42 is mounted on the base plate 7. The support plate 21 and the positioning block 31 are detachably mounted on the base plate by bolts. When processing different models of sheaths, the corresponding positioning block 31 can be replaced. The base plate 7 can improve the convenience of overall device movement and also improve the overall stability of the device. The housing 6 is used to protect the internal device. The housing 6 is provided with a pipe installation through hole. The pressure regulator is located on the outside of the housing to facilitate adjustment of the initial air pressure value. One end of the pipe is connected to the pressure regulator, and the other end of the pipe is connected to the pneumatic pressure dividing valve inside the housing through the installation through hole.
