Description

Technical Field

[0001] The invention relates to the field of automobile final assembly, in particular to an automobile ESP assembly and brake pipe subassembly positioning device and method. Background Art

[0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] There are many differences in the current car models in the market, and the pipeline layout of each OEM model is quite different. The pipeline layout of different models needs to be controlled during the assembly process to meet the design definition. Among them, the ESP assembly (electronic stability system) to the front and rear combination valve left / right brake exhaust pipe needs to adopt a sub-assembly process to ensure product assembly consistency and avoid risk quality problems such as pipeline connection interference, deformation, and de-stuck.

[0004] For this purpose, it is necessary to use external auxiliary tooling to sub-assemble and position the ESP assembly and the brake pipe. For example, Chinese patent application CN201720056930.8, filed on January 18, 2017, discloses a sub-assembly fixture for an automobile ESC and a brake pipe, which is provided with a workbench, on which a fixed base, an ESC clamping mechanism and a brake pipe positioning and installation mechanism are fixed, which can achieve the positioning accuracy of the brake pipe, but there are the following problems:

[0005] When the brake drain pipe is installed on the ESP, the direction of the brake drain pipe is to bend upward first, bypass the ESP and then come to the lower side of the ESP. After the brake drain pipe is installed on the ESP, it is necessary to press the brake drain pipe manually to tighten the nut of the brake drain pipe with an open-end wrench. One person presses the pipe and performs torque operation at the same time, which is inconvenient to operate and the assembly quality cannot be guaranteed. If multiple people cooperate, there is a problem of wasting manpower. Because there is no external restriction, when one of the brake drain pipes is tightened, the other untightened brake drain pipes are easy to detach from the ESP. In this way, when the next brake drain pipe is tightened, it needs to be installed and tightened again, affecting the assembly efficiency. Summary of the invention

[0040] As introduced in the background technology, in the prior art, when the brake pipe is connected to the ESP assembly, the operator needs to press the brake pipe before applying torque. In order to solve the above technical problem, the present invention proposes a vehicle ESP assembly and brake pipe assembly and positioning device.

[0041] Embodiment 1

[0043] Considering the structural setting, the fixing frame 6 is L-shaped, the fixing frame 6 is arranged higher than the supporting frame, the bottom of the fixing frame is fixed to the workbench 8, and a lifting component is arranged on one side of the top of the fixing frame.

[0044] Among them, the clamping component 12 is detachably connected to the lifting component, and the clamping component 12 includes a supporting member, a flexible member is arranged on the side of the supporting member facing the supporting frame, and a recess is arranged on the flexible member, and the recess is arranged along the length direction of the brake pipe 15. The shape of the recess 13 is compatible with the shape of the brake pipe it clamps, because the brake pipe 15 is first bent upward into a door shape and then comes to the side of the ESP assembly 14, the length of the recess is smaller than the length of the U-shaped section of the brake pipe, and the flexible member can be a rubber member. During the molding process of the flexible member, the shape of the recess is contoured according to the brake pipe.

[0045] It is understandable that the lifting component is an existing lifting cylinder or a quick clamp 11 , and the lifting component such as a support plate of the quick clamp is detachably mounted on the end of the horizontal section of the fixed frame, and the bottom end of the quick clamp is connected to the clamping component 12 .

[0046] In this embodiment, reference Figure 3 and Figure 4 As shown, at least two support frames are provided, namely a first support frame 4 and a second support frame 5. The structure of the first support frame 4 is the same or different. The first support frame 4 and the second support frame 5 are provided with a distance between them. The first support frame 4 is used to assemble a separate ESP assembly 14, that is, the ESP body and the mounting frame 16 are supported at the first support frame, and a fixing frame 6 is provided on the side of the second support frame 5.

[0047] In this embodiment, the support frame includes a base 17, which is fixed to the workbench 8. The base can be a flat plate. The base supports two lateral frames 18. The lateral frames on both sides are arranged parallel to each other. A support portion is respectively arranged on the top of each lateral frame. The distance between the two lateral frames is set to accommodate the mounting frame 16 in the middle of the ESP assembly. The two support portions cooperate to support the ESP assembly. The plane where the fixing frame 6 is located is located between the lateral frames on both sides.

[0048] One of the support parts is L-shaped, and the other support part is provided with an arc-shaped groove 19 on the top. The horizontal section of the L-shaped support part 20 supports the bottom of the ESP assembly, and the vertical section of the L-shaped support part 20 is closed or open. The vertical section of the L-shaped support part of the first support frame is closed, and the L-shaped support part of the second support frame is hollow and open. When the vertical section of the L-shaped support part 20 is open, the setting path of the brake drain pipe 15 is guaranteed.

[0049] It should be noted that two limit blocks 21 are also arranged on the surface of the workbench 8, one of which is set at a distance between the limit block 21 and the second support frame 5, and the limit block 21 is set along the path direction of the brake pipe. The two limit blocks 21 are set parallel to each other, and a limit groove 22 is opened on the top side of the limit block 21. Multiple brake pipes 15 are set through the limit groove 22. The limit block 21 is set on one side of the L-shaped support part 20 in the second support frame 5. In this way, the brake pipe 15 passes through the hollow part of the L-shaped support part to reach the first limit block, and then continues to extend outward after passing through the limit groove 22 of the other limit block.

[0050] In addition, in this embodiment, reference Figure 6As shown, a support clamp 24 is provided on one side of the first limit block 21 close to the second support frame, and a support clamp 24 is also provided on the side of the second limit block away from the first limit block. The support clamp 24 is provided with a plurality of clamping openings, and the size of the clamping openings is adapted to the size of the brake pipe 15 (the brake pipe is also called the brake oil pipe). The support clamp 24 supports a plurality of brake pipes arranged side by side at the same time, thereby ensuring the distance between the brake pipes and avoiding the problem of the pipes coming off.

[0051] It is easy to understand that the body 1 is a frame structure, and supporting feet 9 are arranged at the bottom of the frame 1, and the supporting feet 9 are anchor bolts. A workbench 8 is arranged on the upper side of the body, and a support plate 23 is arranged on the lower side. The support plate 23 is located below the workbench. The workbench is also provided with a material box 3. Specifically, a plurality of openings are arranged on the surface of the workbench, and the top of the material box 3 is hung at the opening of the workbench. The material box 3 can be arranged on the side of the support frame. The workbench is also provided with a ring-shaped tray 2, which is arranged on the outer side of the workbench 8. The material box 3 is used to place materials, and the ring-shaped tray 2 can be used to set the torque wrench.

[0052] The device provided in this embodiment, after the brake drain pipe 15 is pre-installed from the threaded cavity of the ESP assembly 14, the clamping component is driven by the lifting component to move toward the brake drain pipe. The part of the brake drain pipe at the connection with the ESP assembly protrudes upward relative to the ESP assembly 14 at this time and then bends to the side of the ESP assembly. The protruding section located on the upper side of the ESP assembly 14 can be inserted into the corresponding recess of the clamping component, and the clamping component provides a downward clamping force to the brake drain pipe from above. In this way, the industry can tighten the nut of the brake drain pipe conveniently without the cooperation of other personnel. The operation is convenient and simple, and the ergonomics is reasonable. It can be compatible with different ESP assemblies and brake drain pipes of the same platform and co-line models for separate packaging. When a new model is introduced, only the clamping component needs to be replaced. The modification cost is low and the modification time is short. While saving the modification cost, the labor intensity of personnel is reduced and the line side packaging space is saved.
