Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of automobile air-conditioning pipeline production, in particular to a positioning tool for producing automobile air-conditioning pipeline samples. Background Art
[0002] The automobile air conditioning pipeline is an important part of the automobile air conditioning system. Its role is to connect the air conditioning components scattered inside the car body so that the entire air conditioning system can work in an orderly manner. The positioning tool is mainly used to solve the problems of long development cycle and high production cost of the existing automobile air conditioning pipeline assembly positioning tool. It combines components such as the bottom plate, the pressure plate positioning adjustment mechanism and the aluminum tube fixing bracket to achieve fast and accurate automobile air conditioning pipeline sample production.
[0003] Automobile air conditioning pipelines need to be connected to various components, and may need to cross other components or obstacles in the middle, causing the pipelines to bend or turn. Due to the inconsistent bending of automobile air conditioning pipelines, the bends cannot be well fixed on the positioning tooling. When both ends of the pipeline need to be tested for air tightness or the pipeline needs to be tested, the position of the pipeline on the tooling is unstable, and the pipeline may be damaged by external force or extrusion. If the pipeline cannot be stably fixed on the tooling, it may cause the pipeline to move or shake during the test, thereby affecting the accuracy of the test results. Position instability during the test process will lead to errors in the air tightness test, which may miss potential problems or lead to misjudgment. During the air tightness test, the pipeline needs to withstand a certain pressure. If the position is unstable, it is easy to cause the pipeline to leak or rupture. Utility Model Content
[0004] The utility model aims to provide a positioning tool for manufacturing automobile air-conditioning pipeline samples to solve the problems raised in the above-mentioned background technology.
[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0006] A positioning tool for manufacturing automobile air-conditioning pipeline samples, comprising:
[0007] A support plate, with a fixing frame disposed above the support plate for fixing both ends of the pipeline;
[0008] A placing rack 1 and a placing rack 2 are arranged above the support plate, and a connecting rod 1 and a connecting rod 2 are arranged below the placing rack 1 and the placing rack 2. The outer surfaces of the connecting rod 1 and the connecting rod 2 are both provided with limiting rings for adjusting the positions of the placing rack 1 and the placing rack 2.
[0009] Preferably, the tops of the first placement rack and the second placement rack are both configured as curved surfaces, and the fixing rack is provided with a fixing clamp to clamp and fix the pipeline.
[0010] Preferably, a groove is provided through the support plate, and the outer surfaces of the connecting rod 1 and the connecting rod 2 slide in the groove.
[0011] Preferably, the placing rack 1 and the placing rack 2 slide on the supporting plate through the connecting rod 1 and the connecting rod 2 inside the groove.
[0012] Preferably, sliding grooves are symmetrically provided below the support plates, and sliding blocks are slidably connected in the sliding grooves.
[0013] Preferably, the sliding blocks are connected to the ends of the limiting rings, and the ends of the limiting rings are penetrated by threaded rods.
[0014] Preferably, a first limit block and a second limit block are provided on the outer surface of the threaded rod, and the first limit block and the second limit block are fixedly connected to the threaded rod.
[0015] Preferably, the limiting block 1 and the limiting block are both located at both sides of the end of the limiting ring, and a fixing block is threadedly connected to the threaded rod, and the fixing block is fixedly connected to the bottom of the support plate.
[0016] Compared with the prior art, the utility model has the following beneficial effects:
[0017] By adjusting the position of the limit ring, the placement rack one and the placement rack two are prompted to move, and the placement rack one and the placement rack two are fixed to the bend of the air-conditioning pipeline, and then the two ends of the pipeline are fixed by the fixing frame above the support plate, thereby realizing three-point reinforcement of the pipeline, increasing the stability of the pipeline and the overall carrying capacity. When the pipeline is reinforced, it is not easily disturbed and affected by external forces, thereby reducing the risk of vibration and deformation of the pipeline caused by external forces.
[0018] By adjusting the position of the limit ring through the threaded rod, the tooling can adapt to the fit and fixation of air-conditioning pipes of different shapes and sizes, which can effectively deal with pipes of different specifications, improve the scope of application and flexibility of the tooling, and adjusting the threaded rod is simpler than replacing tooling of different sizes, saving the operator's time and energy. The fit and fixation of the pipe can be achieved by simply adjusting the threaded rod, which is more convenient and quicker to operate. The threaded rod drives the multiple groups of placement racks 1 and 2 on the top of the placement plate to adjust, so that multiple stations can achieve synchronous adjustment, ensuring that multiple stations reach the required position or angle simultaneously and accurately.

The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations. The basic principles of the utility model defined in the following description can be used for other implementation schemes, variations, improvements, equivalent schemes, and other technical solutions that do not deviate from the spirit and scope of the utility model.
[0028] Those skilled in the art should understand that, in the disclosure of the present invention, the directions or positions indicated by the terms "longitudinal", "lateral", "up", "down", "left", "right", "front", "back", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc. are based on the directions or positional relationships shown in the accompanying drawings, which are only simplified descriptions for the convenience of describing the present invention, and do not indicate or imply that the device or component referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, the above terms should not be understood as limitations on the present invention.
[0029] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the element may be multiple, and the term "one" should not be understood as a limitation on the quantity. Example
[0030] See also Figure 1-Figure 5 , a positioning tool for making a sample of an automobile air-conditioning pipeline, comprising:
[0031] A support plate 1, with a fixing frame 2 disposed above the support plate 1 for fixing both ends of the pipeline;
[0032] A placing rack 1 3 and a placing rack 2 4 are arranged above the support plate 1, and a connecting rod 1 6 and a connecting rod 2 7 are arranged below the placing rack 1 3 and the placing rack 2 4. The outer surfaces of the connecting rod 1 6 and the connecting rod 2 7 are provided with a limiting ring 10 for adjusting the position of the placing rack 1 3 and the placing rack 2 4.
[0033] By adjusting the position of the limit ring 10, the placement rack 1 3 and the placement rack 2 4 are moved, and the placement rack 1 3 and the placement rack 2 4 are fixed to the bending part of the air conditioning pipeline, and then the two ends of the pipeline are fixed by the fixing frame 2 above the support plate 1, so as to achieve three-point reinforcement of the pipeline. Through three-point reinforcement, that is, the placement rack 1 3, the placement rack 2 4 and the fixing frame 2 above the support plate 1 jointly fix the pipeline, the stability of the pipeline on the tooling is increased, and the pipeline will not move or shake due to unstable position, ensuring the accuracy and stability of the pipeline during inspection or maintenance.
[0034] Among them, the tops of the placement rack 1 3 and the placement rack 2 4 are both set as curved surfaces, which can better fit the outer surface of the pipeline, and the fixing frame 2 is provided with a fixing clamp to clamp and fix the pipeline. A groove 5 is provided through the support plate 1, and the outer surfaces of the connecting rod 1 6 and the connecting rod 2 7 slide in the groove 5. The placement rack 1 3 and the placement rack 2 4 slide on the support plate 1 through the connecting rod 1 6 and the connecting rod 2 7 inside the groove 5. When the limiting ring 10 moves, the placement rack 1 3 and the placement rack 2 4 on the top of the connecting rod 1 6 and the connecting rod 2 7 are driven to move, thereby prompting the placement rack 1 3 and the placement rack 2 4 to fit the bending part of the automobile air-conditioning pipeline to limit it.
[0035] Furthermore, the support plate 1 is symmetrically provided with a slide groove 8 below, and a slider 9 is slidably connected in the slide groove 8. The sliders 9 are connected to the ends of the limit rings 10, and the ends of the limit rings 10 are penetrated by a threaded rod 12. The outer surface of the threaded rod 12 is provided with a limit block 11 and a limit block 2 14, and the limit block 11 and the limit block 2 14 are fixedly connected to the threaded rod 12. The position of the limit ring 10 is adjusted by rotating the threaded rod 12, thereby enabling the placement rack 1 3 and the placement rack 2 4 to adapt to the fixing of automobile air-conditioning pipes of different lengths and shapes. The threaded rod 12 drives the multiple groups of placement racks 1 3 and the placement rack 2 4 on the top of the support plate 1 to adjust, so as to enable multiple stations to achieve synchronous adjustment, ensuring that multiple stations reach the required position or angle simultaneously and accurately.
[0036] The threaded rod 12 can be rotated manually or driven by an external drive motor to achieve accurate adjustment of multiple positions.
[0037] It should be added that when the threaded rod 12 is rotated, one end of the threaded rod 12 with the limit block 11 and the limit block 2 14 installed rotates in the limit ring 10. When the threaded rod 12 moves toward the end of the support plate 1, the limit ring 10 moves synchronously, driving the placement frame 1 3 and the support frame 2 to move toward the end of the support plate 1. When the threaded rod 12 moves toward the middle of the support plate 1, the limit ring 10 drives the placement frame 1 3 and the placement frame 2 4 to move to a position close to the middle of the support plate 1, which is suitable for the fixation of air-conditioning pipelines of different sizes, and the limit ring 10 on which side can be adjusted can be selected according to the pipeline status, thereby increasing the applicability of the equipment.
[0038] Furthermore, the limit block 11 and the limit block are located on both sides of the end of the limit ring 10, and a fixed block 13 is threadedly connected to the threaded rod 12, and the fixed block 13 is fixedly connected to the bottom of the support plate 1. The fixed block 13, the limit block 11 and the limit block 2 14 provide stable supporting force when the threaded rod 12 moves, and cooperate with the slider 9 connected to the limit ring 10 inside the slide groove 8 to ensure the stability of movement.
