The first positioning mechanism includes two positioning pin assemblies. The fixture body is provided with two third elongated holes extending along the left-right direction of the vehicle body. The lower ends of the two positioning pin assemblies are detachably fixed at the two third elongated holes, and the upper ends of the two positioning pin assemblies are respectively used to be inserted into the positioning holes on the left longitudinal beam and the right longitudinal beam of the chassis.

[0010] Optionally, the positioning pin assembly includes a pin seat and a positioning pin, the positioning pin being detachably fixed to the pin seat; the pin seats of the two positioning pin assemblies are respectively detachably fixed to the two third elongated holes, the positioning pins of the two positioning pin assemblies are respectively used to be inserted into the positioning holes on the left longitudinal beam and the right longitudinal beam of the chassis, and the upper end faces of the pin seats of the two positioning pin assemblies are respectively used to abut against the lower end faces of the left longitudinal beam and the right longitudinal beam of the chassis.

[0011] Optionally, a first anti-slip structure is provided at the connection between the tooling body and the pin seat. The first anti-slip structure is used to increase the frictional resistance when the pin seat moves relative to the tooling body in the left-right direction.

[0012] Optionally, the first anti-slip structure includes a plurality of first anti-slip teeth and a plurality of second anti-slip teeth. The plurality of first anti-slip teeth are laid along the left-right direction on the part of the tooling body where the third elongated hole is provided, and the plurality of second anti-slip teeth are laid along the left-right direction on the pin seat, and the first anti-slip teeth and the second anti-slip teeth mesh with each other.

[0013] Optionally, the shock absorber tower assembly manufacturing fixture further includes a second positioning mechanism, which is located on one side of the second positioning mechanism along the left-right direction.

[0015] The beneficial effects of the shock absorber tower pack manufacturing fixture of this utility model are: the tower pack positioning mechanism can be installed on the fixture body by connecting the base of the tower pack positioning mechanism to the fixture body; at the same time, by setting an adjustment component in the tower pack positioning mechanism and connecting the adjustment component to the base, the tower pack positioning component can be detachably connected to the upper end of the adjustment component, so as to use the adjustment component to adjust the spatial angle of the upper end face of the tower pack positioning component. In this way, before modifying the shock absorber tower pack, the position of the tower pack positioning part (i.e., the tower pack positioning part blank) relative to the vehicle body can be roughly adjusted on a machining equipment such as a CNC machine tool, with machining allowance. Then, the spatial angle of the upper end face of the tower pack positioning part blank is adjusted using an adjustment component so that the spatial angle of the upper end face of the tower pack positioning part blank is approximately close to the angle of the upper end face of the shock absorber tower pack of the vehicle body. Then, the tower pack positioning part blank is machined to obtain a tower pack positioning part that matches the shock absorber tower pack of the vehicle body. This achieves the goal of machining the tower pack positioning part in one go, so that the shock absorber tower pack manufacturing tooling can be replaced by remachining the tower pack positioning part to adapt to the suspension system of different modified vehicles. This eliminates the need to develop a special modification tooling for each vehicle body, thereby shortening the development cycle and development cost of the shock absorber tower pack manufacturing tooling and improving the modification efficiency of the vehicle suspension system. In addition, the adjustment components allow the shock absorber tower housing manufacturing tooling to coarsely adjust the spatial angle of the upper end face of the tower housing positioning part blank when the machining allowance in the thickness direction of the tower housing positioning part blank is small. This spatial angle is made to be approximately close to the angle of the upper end face of the shock absorber tower housing of the vehicle to be modified relative to the vehicle body. Then, the tooling is processed to obtain a tower housing positioning part that matches the shock absorber tower housing of the vehicle to be modified. This can save the amount of tower housing positioning part blank used, thereby further reducing the development cost of the shock absorber tower housing manufacturing tooling.

[0022] In related technologies, to shorten the R&D cycle, save R&D costs, and verify the rationality of the vehicle body design structure, it is common practice to test the vehicle under development by modifying some systems of existing similar models. When modifying the chassis suspension system of existing similar models, a set of suspension system modification tooling needs to be developed and manufactured for each modified model to ensure the accuracy of the modification and installation. However, this repeated development of the same type of tooling not only wastes financial and material resources but also increases development costs and modification cycles.

[0023] To address the problems existing in the aforementioned related technologies, this utility model provides a manufacturing tooling for a shock absorber tower package.

[0024] Combination Figures 1 to 3As shown in the figure, the present invention provides a shock absorber tower pack manufacturing fixture, including a fixture body 1 and a tower pack positioning mechanism 2. The tower pack positioning mechanism 2 includes a base 21, an adjustment component 22 and a tower pack positioning component 23. The base 21 is connected to the fixture body 1, the adjustment component 22 is connected to the base 21, and the tower pack positioning component 23 is detachably connected to the upper end of the adjustment component 22. The adjustment component 22 is used to adjust the spatial angle of the upper end surface of the tower pack positioning component 23.

[0025] It should be noted that, Figure 1 The X-axis direction in the diagram represents the front-to-back direction of the vehicle body, often referred to simply as the front-to-back direction. Figure 1 The Y-axis direction in the diagram represents the left-right direction of the vehicle body, or simply the left-right direction. Figure 1 The Z-axis direction is the vertical direction of the vehicle body, or simply the vertical direction. The end of the tooling body 1 and other components located in the positive Y-axis direction is the left end of the component, and correspondingly, the end located in the Y-axis direction is the right end of the component.

[0026] It should also be noted that during the modification process, a vehicle model is equipped with two shock absorber tower assembly manufacturing fixtures arranged symmetrically on the left and right sides to modify the left shock absorber tower assembly 300 and the right shock absorber tower assembly 400 of the vehicle body, respectively. The shock absorber tower assembly manufacturing fixture in this embodiment is one of these two fixtures, for example... Figure 2 As shown, the shock absorber tower assembly manufacturing fixture is a left shock absorber tower assembly manufacturing fixture, used for modifying the left shock absorber tower assembly 300 of the vehicle body.

[0027] Specifically, the fixture body 1 is the main supporting structure of the shock absorber tower assembly manufacturing fixture, used to support the tower assembly positioning mechanism 2, and also to support the first positioning mechanism and the second positioning mechanism 4, which will be described later. The fixture body 1 can be as follows: Figure 1 The frame structure shown can also be a flat plate structure, which is not specifically limited here. The tower bag positioning mechanism 2 is installed on the left or right end of the tooling body 1. For example, when the shock absorber tower bag manufacturing tooling is a left shock absorber tower bag manufacturing tooling, the tower bag positioning mechanism 2 is installed on the left end of the tooling body 1; when the shock absorber tower bag manufacturing tooling is a right shock absorber tower bag manufacturing tooling, the tower bag positioning mechanism 2 is installed on the right end of the tooling body 1.

[0028] More specifically, the tower positioning mechanism 2 includes a base 21, an adjustment assembly 22, and a tower positioning component 23 connected sequentially from bottom to top. The base 21 is detachably installed at one end of the tooling body 1 in the left-right direction. The tower positioning component 23 is used to support the shock absorber tower and is inserted into the positioning hole on the shock absorber tower. When inserted, the upper end face of the tower positioning component 23 is parallel to the upper end face of the shock absorber tower. The tower positioning component 23 is detachably installed on the upper end of the adjustment assembly 22 for easy quick replacement. Moreover, the tower positioning component 23 can be made of thermoplastic material, such as ABS plastic, so that it can be processed in one go on a CNC machine tool. Before modifying the shock absorber tower, the position of the tower positioning part 23 (i.e., the tower positioning part blank) relative to the vehicle body can be roughly adjusted on a machining equipment such as a CNC machine tool, according to the vehicle body size of the model to be modified. For example, the position of the tower positioning part blank relative to the vehicle body can be adjusted according to the distance between the left longitudinal beam 100 and the right longitudinal beam 200 of the chassis of the model to be modified, as well as the height of the lower end face of the left longitudinal beam 100 and the right longitudinal beam 200 of the chassis. Then, the spatial angle of the upper end face of the tower positioning part blank is adjusted using the adjustment component 22. This spatial angle is the spatial angle of the upper end face of the tower positioning part blank in the three-dimensional coordinate system of the vehicle body, so that the spatial angle of the upper end face of the tower positioning part blank is approximately close to the angle of the upper end face of the shock absorber tower of the model to be modified relative to the vehicle body. Then, the tower positioning part blank is machined to obtain the tower positioning part 23 that matches the shock absorber tower of the model to be modified, thereby achieving the purpose of machining the tower positioning part 23 in one go. Furthermore, when the tower cushion positioning part blank has sufficient machining allowance, it can be machined directly after adjusting its position relative to the vehicle body. This machining process ensures that the spatial angle of the upper surface of the machined tower cushion positioning part 23 matches the angle of the upper surface of the shock absorber tower cushion of the vehicle to be modified relative to the vehicle body. In other words, when the machining allowance in the thickness direction of the tower cushion positioning part blank is small, the spatial angle of the upper surface of the tower cushion positioning part blank can be coarsely adjusted using the adjustment component 22 to make the spatial angle approximately close to the angle of the upper surface of the shock absorber tower cushion of the vehicle to be modified relative to the vehicle body before machining.

[0029] In this embodiment, the tower bag positioning mechanism 2 can be installed on the tooling body 1 by connecting the base 21 of the tower bag positioning mechanism 2 to the tooling body 1; at the same time, by setting an adjustment component 22 in the tower bag positioning mechanism 2 and connecting the adjustment component 22 to the base 21, the tower bag positioning component 23 can be detachably connected to the upper end of the adjustment component 22, so as to use the adjustment component 22 to adjust the spatial angle of the upper end surface of the tower bag positioning component 23. In this way, before modifying the shock absorber tower pack, the position of the tower pack positioning part 23 (i.e., the tower pack positioning part blank) relative to the vehicle body can be roughly adjusted on a machining equipment such as a CNC machine tool, with machining allowance. Then, the spatial angle of the upper end face of the tower pack positioning part blank is adjusted using the adjustment component 22 so that the spatial angle of the upper end face of the tower pack positioning part blank is approximately close to the angle of the upper end face of the shock absorber tower pack of the vehicle body. Then, the tower pack positioning part blank is machined to obtain the tower pack positioning part 23 that matches the shock absorber tower pack of the vehicle body. This achieves the purpose of machining the tower pack positioning part 23 in one go, so that the shock absorber tower pack manufacturing tooling can be replaced by remachining the tower pack positioning part 23 to adapt to the suspension system of different modified vehicles. This eliminates the need to develop a special modification tooling for each vehicle body, thereby shortening the development cycle and development cost of the shock absorber tower pack manufacturing tooling and improving the modification efficiency of the vehicle suspension system. In addition, the adjustment component 22 allows the shock absorber tower housing manufacturing tooling to use the adjustment component 22 to coarsely adjust the spatial angle of the upper end face of the tower housing positioning component blank when the machining allowance in the thickness direction is small. This makes the spatial angle approximately close to the angle of the upper end face of the shock absorber tower housing of the vehicle to be modified relative to the vehicle body. Then, the tooling is processed to obtain the tower housing positioning component 23 that matches the shock absorber tower housing of the vehicle to be modified. This saves the amount of tower housing positioning component blank used, thereby further reducing the development cost of the shock absorber tower housing manufacturing tooling.

[0030] When modifying and developing a vehicle's suspension system, the mounting position of the chassis longitudinal beams on the vehicle body remains unchanged; instead, the structure of the shock absorber tower and / or its mounting position on the vehicle body are altered. For ease of description, the working principle of the shock absorber tower manufacturing tooling is explained here using the example of changing the mounting position of the shock absorber tower without changing its structure. During modification, the distance between the two positioning pins 32 (described later) in the first positioning mechanism is first adjusted to match the distance between the positioning holes on the left longitudinal beam 100 and the right longitudinal beam 200 of the chassis of the vehicle to be modified. Then, the fixed position of the seat 21 is adjusted in the left-right direction, thereby adjusting the position of the tower positioning component 23 relative to the vehicle body. Next, the shock absorber tower of the vehicle to be modified is cut off and installed onto the tower positioning component 23. Finally, the shock absorber tower manufacturing tooling is assembled onto the cut... On the vehicle to be modified, after the shock absorber tower, two positioning pins 32 are inserted into the positioning holes on the left longitudinal beam 100 and the right longitudinal beam 200 of the chassis of the vehicle to be modified, respectively. The upper end faces of the two pin seats 31 corresponding to the two positioning pins 32 are respectively attached to the lower end faces of the left longitudinal beam 100 and the right longitudinal beam 200 of the chassis to complete the positioning of the manufacturing tooling on the vehicle to be modified. Finally, the shock absorber tower installed on the tower positioning part 23 is welded to the adjusted position to complete the modification.

[0031] Furthermore, combined Figure 4 As shown, the base 21 includes a support column 211 and a base plate 212. The upper end of the support column 211 is connected to the adjustment component 22, and the lower end of the support column 211 is connected to the base plate 212. The base plate 212 is arranged parallel to the upper surface of the tooling body 1 and is detachably fixed to the tooling body 1 by fasteners. In this way, the support column 211 is used to support the adjustment component 22, making the structure of the base 21 simple and easy to implement. At the same time, the base plate 212 increases the connection area between the base 21 and the tooling body 1, improving the stability of the connection.

[0032] Optionally, combined Figure 4 and Figure 5 As shown, the adjustment assembly 22 includes a first turntable 221 and a second turntable 222 arranged opposite to each other. The second turntable 222 is fixed to the upper end of the base 21. The first turntable 221 is located above the second turntable 222 and is detachably fixed to the second turntable 222 by a threaded fastener 81. The upper and lower end faces of the first turntable 221 are set at an angle. The upper end face of the first turntable 221 is connected to the tower bag positioning member 23 and is parallel to the upper end face of the tower bag positioning member 23. The first turntable 221 is used to rotate relative to the second turntable 222 when the threaded fastener 81 is released to adjust the spatial angle of the upper end face of the first turntable 221.

[0033] Specifically, the lower end face of the first turntable 221 and the upper end face of the second turntable 222 are fitted together. Since the upper end face and the lower end face of the first turntable 221 are set at an angle, that is, the thickness of the first turntable 221 is inconsistent in the rotation circumferential direction, the spatial angle of the upper end face of the first turntable 221 will change when the first turntable 221 is rotated relative to the second turntable 222.

[0034] In this optional embodiment, the tower bag positioning member 23 is also disc-shaped. The lower end face of the tower bag positioning member 23 is fitted and connected to the upper end face of the first turntable 221. The upper end face of the first turntable 221 is set to be parallel to the upper end face of the tower bag positioning member 23, so that the spatial angle of the upper end face of the first turntable 221 can reflect the spatial angle of the upper end face of the tower bag positioning member 23. Moreover, by fixing the second turntable 222 to the upper end of the base 21 and keeping it stationary, the first turntable 221 is detachably fixed by threaded fasteners 81 (such as screws). At the upper end of the second turntable 222, the first turntable 221 is fixed on the second turntable 222 when the threaded fastener 81 is locked, so as to ensure that the trolley positioning component 23 will not rotate during the manufacturing and use of the tooling, thereby ensuring the accurate position of the trolley positioning component 23; at the same time, the first turntable 221 can rotate relative to the second turntable 222 when the threaded fastener 81 is released, so as to adjust the spatial angle of the upper end face of the first turntable 221, thereby realizing the adjustment of the spatial angle of the upper end face of the trolley positioning component 23.

[0035] Optionally, combined Figure 5 As shown, both the first turntable 221 and the second turntable 222 are toothed disc structures. The lower end face of the first turntable 221 and the upper end face of the second turntable 222 are engaged by a toothed structure, and the included angle formed by the upper end face and the lower end face of the first turntable 221 is between 3° and 10°.

[0036] In this optional embodiment, the first turntable 221 and the second turntable 222 are configured as toothed disc structures, meaning that the lower end face of the first turntable 221 and the upper end face of the second turntable 222 are respectively provided with mutually meshing tooth structures, thereby achieving mutual meshing between the first turntable 221 and the second turntable 222. Furthermore, during assembly, the two toothed discs can be detachably connected via threaded fasteners 81 and ball washers 82. During adjustment, the first turntable 221 and the second turntable 222 are rotated relative to each other until the spatial angle of the upper end face of the first turntable 221 changes for each tooth offset.

[0037] In addition, since in practical applications, the angle between the upper end face of the shock absorber tower and the horizontal plane is approximately 5° for different vehicle models, in this optional embodiment, by making the upper end face of the first turntable 221 parallel to the lower end face of the second turntable 222, and the lower end face of the first turntable 221 parallel to the upper end face of the second turntable 222, and setting the included angle between the upper and lower end faces of the first turntable 221 to be between 3° and 10°, the difference between the initial spatial angle and the target spatial angle of the upper end face of the tower positioning part blank is small. In this way, the number of adjustments can be reduced and the adjustment efficiency can be improved.

[0038] Optionally, combined Figure 1 and Figure 8 As shown, the tooling body 1 is provided with a first elongated hole extending in the left and right direction along the vehicle body. The tooling body 1 is detachably connected to the seat 21 at the first elongated hole by fasteners.

[0039] In this optional embodiment, the first elongated hole is an oblong hole structure extending in the left-right direction. During assembly, fasteners such as screws and T-nuts 83 can be used to detachably fix the seat 21 to the first elongated hole of the tooling body 1, so that the fixed position of the seat 21 on the tooling body 1 can be adjusted in the left-right direction. This allows the fixed position of the seat 21 to be adjusted left and right according to the body parameters of different vehicle models to be modified, thereby adjusting the fixed position of the tower cushion positioning member 23 installed on the seat 21 by the adjustment component 22, so that the shock absorber tower cushion manufacturing tooling can be adapted to different modified vehicle models.

[0040] Optionally, combined Figure 1 and Figure 8 As shown, the seat 21 is provided with a second elongated hole 2121 extending along the front-rear direction of the vehicle body. The seat 21 is detachably connected to the tooling body 1 at the second elongated hole 2121 by fasteners.

[0041] In this optional embodiment, the second elongated hole 2121 is provided on the base plate 212 of the seat 21, and the second elongated hole 2121 is an oblong hole structure extending in the front-back direction. During assembly, the seat 21 can be detachably fixed to the tooling body 1 at the overlapping part of the first elongated hole and the second elongated hole 2121 using fasteners such as screws and T-nuts 83. This allows the fixed position of the seat 21 and the tower bag positioning member 23 installed on the seat 21 through the adjusting component 22 to be adjusted not only in the left-right direction but also in the front-back direction, thereby further expanding the adjustment range of the fixed position of the tower bag positioning member 23 and improving the versatility of the shock absorber tower bag manufacturing tooling.

[0042] Optionally, combined Figure 1 and Figure 3As shown, a second anti-slip structure 6 is provided at the connection between the tooling body 1 and the seat 21. The second anti-slip structure 6 is used to increase the frictional resistance when the seat 21 moves relative to the tooling body 1 in the left and right directions. Thus, when adjusting the fixed position of the shock absorber tower jack relative to the vehicle body according to the position of the shock absorber tower jack of different models to be modified, that is, when adjusting the fixed position of the seat 21 on the tooling body 1, the second anti-slip structure 6 can be used to increase the frictional resistance between the seat 21 and the tooling body 1, preventing the seat 21 from needing repeated back and forth adjustments due to the large distance moved by the seat 21 in the left and right directions at one time, thereby improving the adjustment efficiency.

[0043] Furthermore, combined Figure 4 and Figure 8 As shown, the second anti-slip structure 6 includes multiple third anti-slip teeth 61 and multiple fourth anti-slip teeth 62. The multiple third anti-slip teeth 61 are laid along the left-right direction on the part of the tooling body 1 where the first elongated hole is provided, and the multiple fourth anti-slip teeth 62 are laid along the left-right direction on the seat 21, and the third anti-slip teeth 61 and fourth anti-slip teeth 62 mesh with each other. In this way, when adjusting the fixed position of the seat 21 on the tooling body 1, the third anti-slip teeth 61 and fourth anti-slip teeth 62 can be used to achieve misalignment adjustment, which not only improves the adjustment efficiency, but also facilitates precise adjustment.

[0044] Optionally, combined Figure 1 , Figure 2 and Figure 3 As shown, the shock absorber tower assembly manufacturing fixture also includes a first positioning mechanism. The tower assembly positioning mechanism 2 is located on one side of the first positioning mechanism along the left and right direction of the vehicle body. The first positioning mechanism includes two positioning pin assemblies 3. The fixture body 1 is provided with two third elongated holes 11 extending along the left and right direction of the vehicle body. The lower ends of the two positioning pin assemblies 3 are detachably fixed at the two third elongated holes 11, and the upper ends of the two positioning pin assemblies 3 are respectively used to be inserted into the positioning holes on the left longitudinal beam 100 and the right longitudinal beam 200 of the chassis.

[0045] In this optional embodiment, since the shock absorber tower mount is located on the side of the chassis longitudinal beam facing outwards, the first positioning mechanism for positioning and connecting with the chassis longitudinal beam is positioned on one side of the tower mount positioning mechanism 2 in the left-right direction to avoid interference with the vehicle body when the shock absorber tower mount manufacturing fixture is installed onto the vehicle body. When using the manufacturing fixture, such as... Figure 2As shown, the manufacturing tooling is positioned on the vehicle to be modified by inserting the upper ends of the two positioning pin assemblies 3 into the positioning holes on the left longitudinal beam 100 and the right longitudinal beam 200 of the chassis, respectively. By setting two positioning pin assemblies 3 on the tooling body 1 and inserting the upper ends of the two positioning pin assemblies 3 into the positioning holes on the left longitudinal beam 100 and the right longitudinal beam 200 of the chassis, the two positioning pin assemblies 3 can be used as reference points for positioning, further ensuring the convenience and accuracy of machining the tower positioning part 23. The two third elongated holes 11 are waist-shaped holes extending in the left-right direction. During assembly, fasteners such as screws and T-nuts 83 can be used to detachably fix the two locating pin assemblies 3 to the two third elongated holes 11 of the tooling body 1, so that the fixed position of the two locating pin assemblies 3 on the tooling body 1 can be adjusted in the left and right direction. In this way, the fixed position of the two locating pin assemblies 3 can be adjusted left and right according to the body parameters of different modified models, so that the shock absorber tower assembly manufacturing tooling can be applied to different modified models.

[0046] Optionally, combined Figure 3 and Figure 6 As shown, the positioning pin assembly 3 includes a pin seat 31 and a positioning pin 32. The positioning pin 32 is detachably fixed to the pin seat 31. The pin seats 31 of the two positioning pin assemblies 3 are detachably fixed to the two third elongated holes 11 respectively. The positioning pins 32 of the two positioning pin assemblies 3 are respectively used to be inserted into the positioning holes on the left longitudinal beam 100 and the right longitudinal beam 200 of the chassis. The upper end faces of the pin seats 31 of the two positioning pin assemblies 3 are respectively used to fit against the lower end faces of the left longitudinal beam 100 and the right longitudinal beam 200 of the chassis.

[0047] In this optional embodiment, the pin seat 31 and the positioning pin 32 can be cylindrical structures. The pin seat 31 has a slot for inserting the positioning pin 32, and a locking hole 311 is provided on its side. During assembly, the two pin seats 31 are first detachably fixed to the two third elongated holes 11 of the tooling body 1 using fasteners such as screws and T-nuts 83. Then, the positioning pin 32 is inserted into the slot of the pin seat 31 and locked onto the pin seat 31 by screws screwed into the locking hole 311 from the side of the pin seat 31. By detachably fixing the positioning pin 32 to the pin seat 31, the positioning pin 32 can be disassembled and replaced. Furthermore, after releasing the locking between the pin seat 31 and the tooling body 1, the fixed position of the pin seat 31 at the third elongated hole 11 can be adjusted by moving the two pin seats 31 in the left-right direction, thereby adjusting the distance between the two positioning pins 32. In addition, when the distance between the positioning holes on the left longitudinal beam 100 and the right longitudinal beam 200 of the chassis of the vehicle to be modified is small compared with the initial distance between the two positioning pins 32, the positioning pin 32 (which can be called the first positioning pin) near the tower positioning mechanism 2 can be adjusted in the left and right directions to match the positioning holes on the left longitudinal beam 100 of the chassis of the vehicle to be modified, and used as the origin of the coordinates in the X and Y directions on the CNC machine tool. At the same time, the upper surfaces of the two pin seats 31 that are respectively used to fit with the lower end surfaces of the left longitudinal beam 100 and the right longitudinal beam 200 of the chassis of the vehicle to be modified are used as reference surfaces for positioning in the Z direction. Then, the outer diameter of the positioning pin 32 (which can be called the second positioning pin) away from the tower positioning mechanism 2 is reduced by machining on the CNC machine tool, so that the distance between the first positioning pin and the machined second positioning pin reaches the target distance value, thereby improving the convenience and accuracy of adjusting the distance between the two positioning pins 32.

[0048] Optionally, combined Figure 3 and Figure 6 As shown, a first anti-slip structure 5 is provided at the connection between the tooling body 1 and the pin seat 31. The first anti-slip structure 5 is used to increase the frictional resistance of the pin seat 31 relative to the tooling body 1 when moving in the left and right directions. Thus, when adjusting the distance between the positioning pins 32 of the two positioning pin assemblies 3 according to the distance between the positioning holes on the left longitudinal beam 100 and the right longitudinal beam 200 of the chassis of different models to be modified, that is, when adjusting the fixed position of the pin seat 31 of the two positioning pin assemblies 3 on the tooling body 1, the first anti-slip structure 5 can be used to increase the frictional resistance between the pin seat 31 and the tooling body 1, preventing the pin seat 31 from needing repeated back-and-forth adjustments due to the large distance moved in one go in the left and right directions, thereby improving the adjustment efficiency.

[0049] Furthermore, combined Figure 6As shown, the first anti-slip structure 5 includes multiple first anti-slip teeth 51 and multiple second anti-slip teeth 52. The multiple first anti-slip teeth 51 are laid along the left-right direction on the part of the tooling body 1 where the third elongated hole 11 is provided, and the multiple second anti-slip teeth 52 are laid along the left-right direction on the pin seat 31, and the first anti-slip teeth 51 and the second anti-slip teeth 52 mesh with each other. In this way, when adjusting the distance between the positioning pins 32 of the two positioning pin assemblies 3, the first anti-slip teeth 51 and the second anti-slip teeth 52 can be used to achieve misalignment adjustment, thereby improving the adjustment efficiency. Furthermore, when the distance between the positioning holes on the left longitudinal beam 100 and the right longitudinal beam 200 of the chassis of the vehicle to be modified is not an integer millimeter, the second positioning pin with machining allowance can be installed on the corresponding pin seat 31 before modification. Then, the distance between the two pin seats 31 can be adjusted to an integer millimeter closest to the target distance value. Then, the outer diameter of the second positioning pin can be reduced by machining on a CNC machine tool, so that the distance between the first positioning pin and the machined second positioning pin reaches the target distance value. In this way, the distance accuracy between the two positioning pins 32 can be controlled within 0.1mm, thereby achieving precise adjustment and further expanding the applicability of the manufacturing tooling. In addition, the machining operation of the second positioning pin can be completed at the same time as machining the tower housing positioning part 23, so that machining can be completed in one go without the need for three-coordinate inspection, further improving the convenience of adapting the shock absorber tower housing manufacturing tooling to different modified vehicle models.

[0050] Optionally, combined Figure 1 , Figure 2 and Figure 3 As shown, the shock absorber tower assembly manufacturing fixture also includes a second positioning mechanism 4. The tower assembly positioning mechanism 2 is located on one side of the second positioning mechanism 4 in the left-right direction. The second positioning mechanism 4 includes a first positioning boss 41 and a second positioning boss 42. The fixture body 1 is provided with two fourth elongated holes 12 extending in the front-rear direction of the vehicle body. The first positioning boss 41 and the second positioning boss 42 are respectively detachably fixed at the two fourth elongated holes 12, and the upper end faces of the first positioning boss 41 and the second positioning boss 42 are respectively used to fit against the lower end faces of the left longitudinal beam 100 and the right longitudinal beam 200 of the chassis.

[0051] In this optional embodiment, similar to the principle of the first positioning mechanism being located on one side of the shock absorber tower positioning mechanism 2 along the left-right direction, the second positioning mechanism 4 is also located on one side of the shock absorber tower positioning mechanism 2 along the left-right direction to avoid interference with the vehicle body when the shock absorber tower manufacturing fixture is installed onto the vehicle body. When using the manufacturing fixture, such as... Figure 2As shown, the upper surfaces of the first positioning boss 41 and the second positioning boss 42 are respectively attached to the lower surfaces of the left longitudinal beam 100 and the right longitudinal beam 200 of the chassis to position the manufacturing tooling on the vehicle to be modified. By setting a second positioning mechanism 4 on the tooling body 1, and having the upper end faces of the first positioning boss 41 and the second positioning boss 42 of the second positioning mechanism 4 respectively abut against the lower end faces of the left longitudinal beam 100 and the right longitudinal beam 200 of the chassis of the vehicle to be modified, the tooling is positioned in the Z-axis direction. Therefore, in addition to using the upper end faces of the two pin seats 31 as reference surfaces for positioning in the Z-axis direction, and using the two positioning pins 32 as reference points to match the positioning holes on the chassis longitudinal beams for positioning in the X-axis and Y-axis directions, the upper end faces of the first positioning boss 41 and the second positioning boss 42 can also be used as reference surfaces for positioning in the Z-axis direction to improve the positioning effect of the tooling, thereby further ensuring the convenience and accuracy of machining the tower positioning parts 23. The two fourth elongated holes 12 are waist-shaped hole structures extending in the front-rear direction. During assembly, fasteners such as screws and T-nuts 83 can be used to detachably fix the first positioning boss 41 and the second positioning boss 42 to the two fourth elongated holes 12 of the tooling body 1, so that the fixed positions of the first positioning boss 41 and the second positioning boss 42 on the tooling body 1 can be adjusted in the front and rear direction. In this way, the fixed positions of the first positioning boss 41 and the second positioning boss 42 can be adjusted in the front and rear according to the body parameters of different modified models, so that the shock absorber tower assembly manufacturing tooling can be applied to different modified models.

[0052] Optionally, combined Figure 1 and Figure 7 As shown, the second positioning boss 42 is located on the side of the first positioning boss 41 away from the tower bag positioning mechanism 2, and the second positioning boss 42 is provided with a fifth elongated hole 421 extending in the left and right direction. The second positioning boss 42 and the tooling body 1 are detachably connected at the fifth elongated hole 421 and the corresponding fourth elongated hole 12 by fasteners.

[0053] In this optional embodiment, the fifth elongated hole 421 is an oblong hole structure extending in the left-right direction. By providing the fifth elongated hole 421 on the second positioning boss 42, the fixed position of the second positioning boss 42 on the tooling body 1 can be adjusted in the left-right direction. Furthermore, based on the fact that the fixed positions of the first positioning boss 41 and the second positioning boss 42 can be adjusted in the front-back direction, the fixed position of the second positioning boss 42 can be further adjusted left-right to make the distance between the first positioning boss 41 and the second positioning boss 42 match the distance between the left longitudinal beam 100 and the right longitudinal beam 200 of the chassis of the vehicle to be modified. This ensures that the first positioning boss 41 and the second positioning boss 42 can respectively fit against the lower end faces of the left longitudinal beam 100 and the right longitudinal beam 200 of the chassis of the vehicle to be modified, thereby achieving the positioning function of the reference surface and further improving the versatility of the shock absorber tower assembly manufacturing tooling.

[0054] Optionally, combined Figure 1 and Figure 3 As shown, a third anti-slip structure 7 is provided at the connection between the tooling body 1 and the first positioning boss 41, and at the connection between the tooling body 1 and the second positioning boss 42. The third anti-slip structure 7 is used to increase the frictional resistance when the first positioning boss 41 and the second positioning boss 42 move relative to the tooling body 1 in the front-back direction. In this way, when adjusting the fixed position of the positioning boss on the tooling body 1 in the front-back direction, the third anti-slip structure 7 can be used to increase the frictional resistance between the positioning boss and the tooling body 1, preventing the positioning boss from needing repeated back-and-forth adjustments due to the large distance it moves in one step in the front-back direction, thereby improving the adjustment efficiency.

[0055] Furthermore, combined Figure 7 As shown, the third anti-slip structure 7 includes multiple fifth anti-slip teeth 71 and multiple sixth anti-slip teeth 72. The multiple fifth anti-slip teeth 71 are laid along the front-back direction on the part of the tooling body 1 where the fourth elongated hole 12 is provided. The multiple sixth anti-slip teeth 72 are laid along the front-back direction on the first positioning boss 41 and the second positioning boss 42, and the fifth anti-slip teeth 71 and the sixth anti-slip teeth 72 mesh with each other. In this way, when adjusting the fixed position of the positioning boss on the tooling body 1 along the front-back direction, the fifth anti-slip teeth 71 and the sixth anti-slip teeth 72 can be used to achieve misalignment adjustment, which not only improves the adjustment efficiency but also facilitates precise adjustment.

[0056] Although the present invention has been disclosed above, its protection scope is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the protection scope of the present invention.
