Description

Technical Field

[0001] The utility model relates to the technical field of wire harness processing, and particularly relates to a wire harness shell pushing fixture. Background Art

[0002] In the production practice of the electronics industry, the assembly of wire harness finished products and shells is a very common operation process. Especially in fields such as automobiles, aviation, robots, and communications, as an aggregate of multiple wires, the wire harness plays important roles such as conducting current and transmitting signals. The wire harness installation shell can protect the wire interfaces, prevent dust and water, and can also fix and support the wire harness to ensure the stable, safe, and efficient operation of electrical equipment. Currently, the assembly of wire harnesses and shells usually adopts the non-threaded hole threading method, and this method requires a simple, practical, and low-cost tooling fixture to achieve efficient and precise assembly.

[0003] Traditional methods for assembling wire harnesses and shells mainly rely on manual operations, and the actions are relatively complex. Taking the plastic shell and the first wire for 4S, inserting the first wire for 4S, taking the second wire for 3S, inserting the second wire for 4S, and pushing each one forcefully into place for 6S, with a total time of 21S. There are problems such as low efficiency and easy fatigue of the operator. In addition, for the assembly of the shell and the wire harness end, a certain extrusion force is required to ensure a firm connection, and it is difficult for manual operation to guarantee the stability and reliability of the assembly of the wire harness and the shell. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a wire harness shell pushing fixture. The pressing plate and the wire harness fixing block fixedly connected to the telescopic rod of the second stretching device fix the position of the wire harness. The first stretching device pushes the shell fixed by the shell fixing block to move, so that the wire harness is inserted into the shell, reducing manual operation, improving production efficiency, reducing operation costs, and improving product quality.

[0005] The utility model is realized through the following technical solutions:

[0006] A wire harness shell pushing fixture includes a base, a bracket, and also includes a controller. The bracket includes a first bracket and a second bracket, which are respectively fixedly connected to both ends of the top surface of the base. The controller is fixedly connected to the top surface of the base beside the first bracket. The first bracket is fixedly connected with a first stretching device, the second bracket is fixedly connected with a second stretching device. The top of the telescopic rod of the first stretching device is fixedly connected with a shell fixing block, the top of the telescopic rod of the second stretching device is fixedly connected with a pressing plate, and the wire harness fixing block is fixedly connected to the top surface of the base below the second stretching device.

[0007] Furthermore, the first bracket, the first stretching device, the shell fixing block, the wire harness fixing block, the second stretching device, and the second bracket are sequentially arranged on the horizontal axis of the base.

[0008] Further, the first stretching device and the second stretching device are cylinders.

[0009] Further, the telescopic rod of the first stretching device is parallel to the top surface of the base, and the telescopic rod of the second stretching device is perpendicular to the top surface of the base.

[0010] Further, the plastic shell fixing block is slidably connected to the slide rail connected to the top surface of the base.

[0011] Further, the plastic shell fixing block includes a limiting block, a limiting groove fixedly connected to the top surface of the limiting block, and a pressing rod.

[0012] Further, the pressing rod is located above the limiting groove, and one end of the pressing rod is hinged to the limiting block, and the other end is clamped to the limiting block.

[0013] Further, grooves matching the shape of the wire harness are provided on the top surface of the wire harness fixing block and the bottom surface of the pressing plate.

[0014] Compared with the prior art, the utility model has the following obvious advantages:

[0015] First, since the limiting groove and the pressing rod are connected to the limiting block of the plastic shell fixing block of the utility model, and grooves matching the shape of the wire harness are provided on the top surface of the wire harness fixing block and the bottom surface of the pressing plate, the plastic shell and the wire harness can be fixed more stably, ensuring the stability and reliability of the assembly of the wire harness and the plastic shell.

[0016] Second, since the position of the wire harness is fixed by the pressing rod fixedly connected to the telescopic rod of the second stretching device and the wire harness fixing block, and the plastic shell fixed by the plastic shell fixing block is moved by the first stretching device, so that the wire harness is inserted into the plastic shell, manual operation can be reduced, the operation cost can be lowered, and the production efficiency can be improved.

[0017] Third, since the plastic shell fixing block fixedly connected to the top of the telescopic rod of the first stretching device is also slidably connected to the slide rail connected to the top surface of the base, the moving direction of the plastic shell fixing block when it is pushed by the first stretching device can be further limited, better ensuring the accuracy of the assembly of the wire harness and the plastic shell.

[0025] When the utility model is in use, the operator controls the telescopic rod of the first stretching device 5 to contract through the controller 4, pulls the rubber shell fixing block 7 fixedly connected to the top of the telescopic rod to move close to the first stretching device 5, the operator opens the clamping position of the pressure rod 703 connected to the limiting block 701 of the rubber shell fixing block 7, pulls the pressure rod 703 open, inserts the rubber shell 11 into the limiting groove 702 connected to the limiting block 701 of the rubber shell fixing block 7, pulls back the pressure rod 703 to re-clamp, and further fixes the position of the rubber shell 11; after the rubber shell 11 is fixed, the operator controls the telescopic rod of the second stretching device 6 to contract through the controller 4, pulls the pressing plate 9 fixedly connected to the top of the telescopic rod to rise to a high position, aligns the end of the wire harness 12 to be inserted into the rubber shell 11 with the interface of the rubber shell 11, and places it in the groove matching the shape of the wire harness on the wire harness fixing block 8.
