Description

Technical Field

[0001] This application relates to the field of NVH equipment foaming technology, and in particular to a device for replacing rigid pipes with hydraulic oil hoses in NVH equipment foaming equipment. Background Technology

[0002] Foaming equipment is a machine used in product packaging to inject raw materials that can generate plastic foam into the gap between the container and the film-lined contents, forming a foam cushioning material that tightly wraps the contents through a chemical reaction. With the continuous development of automated production technology in the automotive industry, in order to reduce the labor intensity of workers, improve work efficiency, and ensure quality and consistency, the NVH foaming production line for automotive bodies is gradually shifting from manual operation to automated robotic operation.

[0003] Current automotive NVH foaming equipment is equipped with hydraulic units, and the gun is controlled by hydraulic hoses. This causes the hydraulic hoses to vibrate during the gun firing process. Over time, this can cause wear and tear on the hydraulic hoses, leading to oil leaks in the hydraulic lines and frequent production stoppages. Therefore, an improvement has been made to a hydraulic hose replacement device for NVH foaming equipment. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a device for replacing the hydraulic hose with a rigid hose in an NVH (Noise, Vibration, and Harshness) foaming equipment. This device overcomes the deficiencies of existing technologies and aims to solve the problem that hydraulic hoses vibrate during the firing process in existing automotive NVH foaming equipment, leading to wear and tear on the hydraulic hoses and subsequent oil leakage during long-term production.

[0005] To achieve the above objectives, this application provides the following technical solution: a device for replacing the hydraulic hose of an NVH equipment foaming device with a rigid hose, comprising a production workshop and a non-flexible hydraulic hose. The non-flexible hydraulic hose is fixedly installed at the outlet of the hydraulic unit of the NVH equipment. The other end of the non-flexible hydraulic hose is fixedly connected to a rigid hydraulic hose through a connecting valve. A robotic arm is installed inside the production workshop. A foaming gun is fixedly installed at the front end of the robotic arm. Several fixing components are fixedly installed on the side arm of the robotic arm. The robotic arm holds a foaming liquid delivery pipe by fixing components. The foaming liquid delivery pipe is formed by bundling several flexible hydraulic hoses together. The front end of the flexible hydraulic hose is connected to the foaming gun, and the rear end of the flexible hydraulic hose is fixedly connected to the rigid hydraulic hose through a connector assembly.

[0006] By adopting the above technical solution, the flexible hydraulic hose is fixed to the side wall of the robotic arm and limited by a fixing component. This ensures that the flexible hydraulic hose will not jump when the foam gun is fired, thus avoiding wear caused by the jump. Furthermore, this method uses a combination of non-flexible hydraulic hoses, rigid hydraulic hoses, and flexible hydraulic hoses, replacing some wear-prone parts of the flexible hydraulic hose with rigid hydraulic hoses. This prevents the flexible hydraulic hose from breaking due to wear, further improving the safety of the NVH equipment foaming equipment during use.

[0007] As a preferred technical solution of this application, the fixing component consists of a positioning block and a clamping block. The positioning block is fixedly installed on the side wall of the robotic arm. The upper surface of the positioning block has a groove one, and the lower surface of the clamping block has a groove two. The circular groove formed by the groove one and the groove two is adapted to the outer diameter of the foaming liquid delivery pipe which is made of several flexible hydraulic hoses bundled together.

[0008] By adopting the above technical solution, the foaming liquid delivery pipe, which is made of several flexible hydraulic hoses bundled together, is fixed between groove one and groove two through the cooperation between the positioning block and the clamping block, ensuring that the flexible hydraulic hose will not jump during use.

[0009] As a preferred technical solution of this application, a rotating seat is fixedly installed on one side of the upper surface of the positioning block, the clamping block is rotatably connected to the rotating seat, and a fixed seat is fixedly installed on the other side of the upper surface of the positioning block, the fixed seat being fixedly installed with the clamping block by bolts and nuts.

[0010] By adopting the above technical solution, the clamping block and the positioning block are assembled together, and the clamping block can be opened to facilitate the placement of the flexible hydraulic hose inside the fixed component.

[0011] As a preferred technical solution of this application, the inner walls of both groove one and groove two are provided with anti-slip rubber pads, and the anti-slip rubber pads are in contact with the outer wall of the foaming liquid delivery pipe.

[0012] By adopting the above technical solution, the outer surface of the flexible hydraulic hose is protected by setting anti-slip rubber pads.

[0013] As a preferred technical solution of this application, the connector assembly includes a connecting sleeve fixedly sleeved on the flexible hydraulic hose. The outer wall of the connecting sleeve has several expansion joints near the upper end. The outer wall of the connecting sleeve is provided with external threads below the expansion joints. The connecting sleeve is fixedly clamped to the outer wall of the hydraulic rigid pipe by a threaded sleeve. The inner wall of the threaded sleeve is provided with internal threads that are compatible with the external threads.

[0014] By adopting the above technical solution, the expansion joint is squeezed by twisting the threaded sleeve, so as to fix the connecting sleeve onto the hydraulic rigid pipe. Through the cooperation between the connecting sleeve, the expansion joint, the external thread and the threaded sleeve, the flexible hydraulic hose and the hydraulic rigid pipe are fixedly connected together.

[0015] As a preferred technical solution of this application, the inner wall of the production workshop is fixedly installed with mounting blocks by screws, the hydraulic hard pipe is located inside the mounting blocks, and the outer surface of the mounting blocks is symmetrically provided with fixing holes.

[0016] By adopting the above technical solution, hydraulic hard pipes are clamped by setting up installation clamps and fixedly installed on the inner wall of the production workshop.

[0017] As a preferred technical solution of this application, the positioning block, rotating seat, clamping block, fixing seat, bolt and nut are all made of stainless steel.

[0018] By adopting the above technical solutions, it is ensured that the fixing components are not easily corroded and have a long service life.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: In this invention, a fixing component is used to fix the flexible hydraulic hose to the side wall of the robotic arm and limit its movement. This ensures that the flexible hydraulic hose will not jump when the foam gun is fired, thus preventing wear caused by the jump.
