Description

Technical Field

[0001] This utility model relates to the field of gasoline engine assembly auxiliary technology, specifically, it is a gasoline engine return water pipe sub-assembly and positioning tool. Background Technology

[0002] The return hose of a gasoline engine is an important component of the cooling system, mainly used to circulate coolant or antifreeze to ensure stable engine temperature. The return hose typically connects to high-temperature components such as the cylinder head, heater core, or turbocharger, returning to the radiator or expansion tank.

[0003] When disassembling the return water pipe, the angle and position need to be constrained. It is difficult to ensure the correct angle by disassembling manually alone, and the production efficiency is low. Utility Model Content

[0004] The purpose of this utility model is to provide a positioning fixture for the sub-assembly of the return water pipe of a gasoline engine, so as to ensure accurate assembly angle and consistent assembly between different batches during the sub-assembly of the return water pipe, while saving manpower in assembly.

[0005] To achieve the above objectives, the present invention employs the following technical means:

[0006] A gasoline engine return water pipe disassembly and positioning fixture includes a worktable and also includes:

[0007] The first support and positioning mechanism includes a first water pipe support block and a second water pipe support block disposed on both sides of the top surface of the workbench. The top surfaces of the first water pipe support block and the second water pipe support block are respectively constructed with pipe end limiting grooves for limiting the two ends of the return water pipe assembly.

[0008] The second support and positioning mechanism includes a bracket support block disposed between the first water pipe support block and the second water pipe support block. The top surface of the bracket support block is provided with a bracket limiting groove, one end of the bracket limiting groove is provided with a bracket adjusting block, and the end of the bracket limiting groove away from the bracket adjusting block and the top surface of the bracket adjusting block are respectively provided with nut limiting holes.

[0009] Preferably, the pipe end limiting groove includes:

[0010] The first inclined groove is provided on the top surface of the first water pipe support block, and the bottom surface of the first inclined groove is constructed with a first inclined surface that matches the angle of the bend section of the first return water pipe.

[0011] The first horizontal groove is provided on the top surface of the first water pipe support block and adjacent to the first inclined groove. The bottom surface of the first horizontal groove is constructed with a first horizontal extension surface that matches the first horizontal end of the second return water pipe.

[0012] The integrated trough is located on the top surface of the second water pipe support block, and the bottom surface is constructed with a second inclined surface that matches the inclination angle of the connecting branch pipe of the second return water pipe. The side wall of the integrated trough is constructed with a second horizontal trough for accommodating the horizontal end of the first return water pipe.

[0013] The third horizontal groove is located on the top surface of the second water pipe support block and is adjacent to the integrated groove. The bottom surface of the third horizontal groove is constructed with a second horizontal extension surface that matches the second horizontal end of the second return water pipe.

[0014] Furthermore, the bracket limiting groove is a linear through groove provided on the top surface of the bracket support block, the side of the bracket adjusting block facing the other end of the bracket limiting groove is constructed as an arc-shaped surface that fits against the outer wall of the bracket ring plate, the top surface of the bracket adjusting block is constructed as a plane that fits against the bracket ear plate, and the angle between the top surface of the bracket adjusting block and the arc-shaped surface is the same as the angle formed by the bracket ear plate and the bracket ring plate.

[0015] Furthermore, the nut limiting hole includes a countersunk hole, and the bottom surface of the countersunk hole is constructed with an internal hexagonal groove.

[0016] Furthermore, the inner diameter of the countersunk hole is greater than the length of the diagonal of the internal hexagonal slot.

[0017] Furthermore, the first water pipe support block, the second water pipe support block, and the bracket support block are all installed on the workbench by means of bolts.

[0018] This utility model has the following beneficial effects during use:

[0019] During assembly, first place half of the bracket in the bracket limiting groove on the top surface of the bracket support block, and place the ear plate of the bracket on the top surface of the bracket adjusting block. By adjusting the height of the bracket adjusting block, the bracket can be arranged at different angles after assembly. After placing the bracket, place both ends of the second return water pipe (which is a straight main pipe) in their respective pipe end limiting grooves. The branch pipe connected to the wall of the second return water pipe can also be inserted into its corresponding pipe end limiting groove by rotating the second return water pipe along its axis. This ensures that the second return water pipe can be stably supported at a specific angle, facilitating later positioning and assembly. Then, insert both ends of the first return water pipe into their corresponding pipe end limiting grooves and position it on the bracket. In this way, the bracket adjusting block allows the bracket to be assembled at a specific angle after the first and second return water pipes are assembled; the layout of the pipe end limiting grooves ensures that the first and second return water pipes are positioned at a specific angle after assembly. Finally, during the final positioning process of installing the other half of the bracket, a nut with a nut limiting hole is constructed. The nut used to assemble the bracket is then embedded and positioned in the nut limiting hole. At the same time, bolts matching the nut are installed on the bracket. This not only frees up the workers' hands, eliminating the need for them to manually position the nut for assembly, but also limits the insertion depth of the bolts by using the bottom end of the nut limiting hole, ensuring the stability of the assembly and the consistency of the tightness of different batches.

[0031] Please refer to Figures 1 to 4A gasoline engine return water pipe disassembly and positioning fixture, including a worktable 1, and further including:

[0032] The first support and positioning mechanism includes a first water pipe support block 2 and a second water pipe support block 3 disposed on both sides of the top surface of the workbench 1. The top surfaces of the first water pipe support block 2 and the second water pipe support block 3 are respectively constructed with pipe end limiting grooves for limiting the two ends of the return water pipe assembly.

[0033] The second support and positioning mechanism includes a bracket support block 4 disposed between the first water pipe support block 2 and the second water pipe support block 3. The top surface of the bracket support block 4 is provided with a bracket limiting groove 5. One end of the bracket limiting groove 5 is provided with a bracket adjusting block 6. The end of the bracket limiting groove 5 away from the bracket adjusting block 6 and the top surface of the bracket adjusting block 6 are respectively provided with nut limiting holes 7.

[0034] In this way, during assembly, the half-piece bracket can be placed in the bracket limiting groove 5 on the top surface of the bracket support block 4, and the ear plate of the bracket can be placed on the top surface of the bracket adjusting block 6. By setting the height of the bracket adjusting block 6, the bracket can be made to form different angles after assembly. After placing the bracket, the two ends of the second return water pipe 21, which is a straight pipe in the main pipe section, are placed in the corresponding pipe end limiting grooves. The branch pipe connected to the pipe wall of the second return water pipe 21 can also be inserted into the corresponding pipe end limiting groove by rotating the second return water pipe 21 along its axis. This ensures that the second return water pipe 21 can stably support the branch pipe at a specific angle, which is convenient for later positioning and assembly. Then, the two ends of the first return water pipe are respectively inserted into their corresponding pipe end limiting grooves, and the first return water pipe is also positioned on the bracket. In this way, using the bracket adjusting block 6, the bracket can be assembled at a specific angle after the first and second return water pipes 21 are assembled; using the layout of the pipe end limiting grooves, the first and second return water pipes 21 can be kept in a specific angle after assembly. Finally, in the process of installing the other half of the bracket and completing the final positioning, the nut for assembling the bracket is embedded and positioned in the nut limiting hole 7 by constructing a nut limiting hole 7. At the same time, the bolt matching the nut is installed on the bracket. This not only frees the workers' hands, eliminating the need for workers to manually position the nut for assembly, but also uses the bottom end of the nut limiting hole 7 to limit the insertion depth of the bolt, ensuring the stability of the assembly and the consistency of the assembly tightness between different batches.

[0035] Furthermore, regarding the pipe end limiting groove, in order to achieve accurate positioning of the first return water pipe 9 and the second return water pipe 21, the pipe end limiting groove includes:

[0036] The first inclined groove 8 is provided on the top surface of the first water pipe support block 2, and the bottom surface of the first inclined groove 8 is constructed with a first inclined surface 10 that matches the angle of the bend section of the first return water pipe 9.

[0037] The first horizontal groove 11 is provided on the top surface of the first water pipe support block 2 and adjacent to the first inclined groove 8. The bottom surface of the first horizontal groove 11 is constructed with a first horizontal extension surface that matches the first horizontal end of the second return water pipe 21.

[0038] The integrated trough 12 is located on the top surface of the second water pipe support block 3, and its bottom surface is constructed with a second inclined surface 13 that matches the inclination angle of the connecting branch pipe of the second return water pipe 21. The side wall of the integrated trough 12 is constructed with a second horizontal trough 14 for accommodating the horizontal end of the first return water pipe 9.

[0039] The third horizontal groove 15 is located on the top surface of the second water pipe support block 3 and is adjacent to the integrated groove 12. The bottom surface of the third horizontal groove 15 is constructed with a second horizontal extension surface that matches the second horizontal end of the second return water pipe 21.

[0040] Furthermore, the bracket limiting groove 5 is a linear through groove provided on the top surface of the bracket support block 4, and the side of the bracket adjusting block 6 facing the other end of the bracket limiting groove 5 is constructed as an arc-shaped surface 17 that fits against the bracket ring plate 16. The top surface of the bracket adjusting block 6 is constructed as a plane that fits against the bracket ear plate 18. The angle between the top surface of the bracket adjusting block 6 and the arc-shaped surface 17 is the same as the angle between the bracket ear plate 18 and the bracket ring plate 16.

[0041] Furthermore, the nut limiting hole 7 includes a countersunk hole 19, the bottom surface of which is constructed with an internal hexagonal groove 20.

[0042] In this way, the countersunk hole 19 allows for easy placement of the corresponding nut into the internal hexagonal slot 20 before assembling the return water pipe. Simply place the nut horizontally into the countersunk hole 19, and then gently rotate it until it aligns with the internal hexagonal slot 20, allowing it to settle and be positioned within the slot. This matching mechanism between the countersunk hole 19 and the internal hexagonal slot 20 also speeds up the nut insertion process during assembly preparation, improving assembly efficiency.

[0043] Specifically, the inner diameter of the countersunk hole 19 is greater than the length of the diagonal of the internal hexagonal groove 20.

[0044] This ensures that after the nut is placed into the countersunk hole 19, there is enough clearance to turn the nut.

[0045] In addition, the first water pipe support block 2, the second water pipe support block 3, and the bracket support block 4 are all installed on the workbench 1 by bolts.

[0046] In this way, by preparing various first water pipe support blocks 2, second water pipe support blocks 3, and bracket support blocks 4, it is convenient to select and combine support blocks of different specifications according to actual assembly needs, satisfying various assembly states. Moreover, the detachable structure also improves the convenience of maintenance.

[0047] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
