[0002] The automotive wiring harness is the network backbone of the vehicle's electrical circuits; without it, there would be no electrical circuit. A wiring harness is a component that connects the electrical circuits by crimping the sheath to the wires and cables. The sheath is typically made of a plastic metal material to enhance the harness's wear resistance. When crimping the sheath to the wires and cables, the crimping position must be determined, the wires inserted, and finally, the sheath is crimped using a crimping mechanism.

[0003] The common wire harness and cable sheath crimping equipment on the market usually requires manual positioning of the uncrimped position of the sheath. This not only fails to guarantee processing accuracy, but also affects the efficiency of single-piece processing. Utility Model Content

[0004] The purpose of the utility model is to provide a wire harness protective cover crimping device to solve the problems raised in the above background technology.

[0006] Preferably, the hydraulic tooling comprises a plurality of hydraulic blocks gathered toward the center, and the wiring harness is inserted into the positioning groove from a channel formed by the plurality of hydraulic blocks.

[0007] Preferably, the sheath positioning and adjustment assembly includes a fixing bracket, a positioning cylinder fixed on the fixing bracket, and a contact plate provided at the end of the positioning cylinder piston rod for contacting the sheath, and the thickness of the hydraulic block is smaller than the length of the sheath.

[0008] Preferably, at least two serrations are provided on the end surfaces of the hydraulic blocks that converge toward the center.

[0009] Preferably, the contact plate is fixed on a positioning block, and there is a positioning protrusion / positioning groove on the positioning block. The processing table is provided with a positioning groove / positioning protrusion used to cooperate with the positioning protrusion / positioning groove. When the contact plate is in operation, the positioning protrusion and the positioning groove are connected to each other.

[0010] Preferably, the fixed bracket includes two step columns and a fixed plate fixed on the processing table, the positioning cylinder is fixed on the fixed plate, one side of the fixed plate is overlapped on the step of the step column, a fixed cover is provided on the top of the step column, and a shock-absorbing and yielding spring is provided on the step column and located between the fixed cover and the fixed plate.

[0011] Preferably, a fixed compensation assembly is also provided on the processing table, and the fixed compensation assembly includes a pair of clamping rings and a driving cylinder for controlling the opening and closing of the clamping rings. The clamping rings are used to clamp the end of the sheath away from the end positioning groove of the wiring harness, and the pressure applied by the contact plate to the sheath is greater than the friction between the sheath and the clamping ring.

[0012] The beneficial effects of the utility model are as follows: the present invention provides a wiring harness end positioning groove so that the end of the wiring harness can be inserted therein to achieve positioning and fixation. At the same time, the position of the sheath is adjusted by the cooperation between the sheath reference positioning seat and the sheath positioning adjustment component so that it can be automatically positioned on the wiring harness. The process only requires manually putting the sheath on the wiring harness and inserting the wiring harness into the wiring harness end positioning groove to achieve automatic positioning of the sheath, which effectively improves work efficiency.

[0013] Among them, by setting the positioning groove and positioning protrusion, the travel route of the resistance plate will be corrected and confirmed during the process of the positioning cylinder controlling the movement of the resistance plate to ensure the processing accuracy;

[0014] In order to avoid excessive squeezing between the contact plate and the sheath due to the influence of the specifications, quality and position of the sheath, a shock-absorbing and yielding spring is provided to play a buffering and yielding role in movement, thereby avoiding damage to the equipment or product;

[0015] Among them, when the distance between the exposed end of the wire harness and the sheath is small, the height of the wire harness end positioning groove will also become smaller. In this way, if the center of the wire harness is offset, the wire harness will easily break away from the wire harness end positioning groove, which makes it impossible to ensure the production accuracy of the product. By setting a fixed compensation component and fixing the sheath, the wire harness is constrained by the sheath, ensuring the subsequent crimping accuracy of the sheath.

[0022] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more precise definition of the protection scope of the present invention. Example

[0023] See Figure 1 A wire harness protective cover crimping device includes a processing table 1 and a hydraulic tooling arranged thereon. The processing table 1 is provided with a wire harness end positioning groove 12, and a sheath reference positioning seat 13 for positioning the lower end face of the sheath is provided above the wire harness end positioning groove 12. The processing table 1 is also provided with a sheath positioning adjustment component 2 that moves along a fixed stroke. The sheath positioning adjustment component 2 contacts the upper end face of the sheath during the movement stroke and makes the lower end face of the sheath contact smoothly with the sheath reference positioning seat 13 at the end position of the stroke.

[0024] Among them, see Figure 1 、 Figure 3 、 Figure 4 and Figure 5 The hydraulic tooling includes a plurality of hydraulic blocks 11 that converge toward the center, and the wiring harness is inserted into the positioning groove from the channel formed by the plurality of hydraulic blocks 11. In addition, at least two serrations 101 are provided on the end faces of the hydraulic blocks 11 that converge toward the center. This is done to enhance the stability between the sheath and the wiring harness after crimping.

[0025] Among them, see Figure 1 、 Figure 2 and Figure 3The sleeve positioning adjustment assembly 2 includes a fixed bracket, a positioning cylinder 23 fixed on the fixed bracket, and a contact plate 25 provided at the end of the piston rod of the positioning cylinder 23 for contacting the sleeve. The thickness of the hydraulic block 11 is less than the length of the sleeve. The fixed bracket includes two step columns 21 and a fixed plate 22 fixed on the processing table. The positioning cylinder 23 is fixed on the fixed plate 22. One side of the fixed plate 22 overlaps the step of the step column 21. A fixed cover 27 is provided on the top of the step column 21. A shock-absorbing and yielding spring 26 is provided on the step column 21 and is located between the fixed cover 27 and the fixed plate 22. , wherein a connecting plate 28 is fixed on the processing table 1, and at least one positioning protrusion 29 is fixed on the connecting plate 28. In this embodiment, the positioning protrusion 29 is pin-shaped. At the same time, the contact plate 25 is fixed on a positioning block 24. The positioning block 24 is provided with a positioning groove that is aligned with the positioning protrusion 29 and passes through it. In this embodiment, the positioning groove is a hole-shaped positioning groove used to cooperate with the pin-shaped positioning protrusion 29. In the process of the positioning cylinder 23 controlling the positioning block 24 and the contact plate 25 to run along a fixed path, the pin-shaped positioning protrusion 29 is inserted into the hole-shaped positioning groove so that its route accuracy is determined, thereby ensuring the accuracy of the contact plate 25 when it contacts the end face of the sheath.

[0026] See Figure 1 、 Figure 3 A fixed compensation component 3 is also provided on the processing table, and the fixed compensation component 3 includes a pair of clamping rings 32 and a driving cylinder 31 for controlling the opening and closing of the clamping rings 32. The driving stem adopts a conventional finger clamping cylinder. The clamping ring 32 is used to clamp the sheath away from the end of the wiring harness end positioning groove 12. In addition, the pressure applied by the contact plate 25 to the sheath needs to be greater than the friction between the sheath and the clamping ring 32, so as not to affect the normal operation of the sheath positioning adjustment component 2.

[0027] Working principle and process:

[0028] When using this product, the sheath can be manually put into the wiring harness and then inserted into the wiring harness end positioning groove 12. At this time, one end of the sheath will overlap the sheath reference positioning seat 13. Due to the influence of the curvature of the wiring harness, the sheath may not be flat or cannot be overlapped with the sheath reference positioning seat 13. Therefore, after the wiring harness is inserted into the wiring harness end positioning groove 12, it is necessary to start the sheath positioning adjustment component 2. Under the action of the positioning cylinder 23, the contact plate 25 will contact the sheath to complete its positioning on the wiring harness. In addition, when the distance between the exposed end of the wiring harness and the sheath is small, the sheath is initially fixed by adding a fixed compensation component 3. In this way, under the limitation of the two points of the wiring harness end positioning groove 12 and the top of the sheath, the wiring harness will not be affected by the center offset and will not be separated from the wiring harness end positioning groove 12, thereby ensuring the processing accuracy.

[0029] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, is also included in the patent protection scope of the present invention.
