Description

Technical Field

[0001] This utility model relates to the field of automotive positioning tooling technology, specifically a flexible positioning tooling for a commercial vehicle axle housing leaf spring. Background Technology

[0002] In the commercial vehicle manufacturing sector, the assembly precision of axle housing leaf springs directly affects the vehicle's load-bearing capacity, driving stability, and safety.

[0003] Traditional commercial vehicle axle housing leaf spring positioning fixtures are mostly rigid structures. During assembly, due to their poor flexibility and adaptability, they are prone to large assembly errors, resulting in inaccurate axle housing leaf spring installation positions. Furthermore, the clamping methods for the half-shaft sleeve and half-housing are relatively simple, and the components are prone to shaking or displacement during assembly, making it difficult to ensure the accuracy and stability of positioning.

[0004] Therefore, this utility model provides a flexible positioning tooling for commercial vehicle axle housing leaf springs to solve the above problems. Summary of the Invention

[0005] (a) Technical problems to be solved

[0006] This utility model provides a flexible positioning tooling for axle housing leaf spring in commercial vehicles, which aims to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A flexible positioning fixture for a commercial vehicle axle housing leaf spring includes a base plate and a pressing mechanism, the pressing mechanism being fixedly installed at the center of the back of the base plate.

[0009] The base plate has a base fixedly installed on both sides of the top. A V-shaped block is slidably installed on the top of the base. A half-shaft sleeve is fixedly snapped onto the top of the V-shaped block. A half-shell is fixedly connected to one side of the surface of the half-shaft sleeve.

[0010] The extrusion mechanism includes a hydraulic cylinder, a hydraulic telescopic rod is fixedly connected to one side of the hydraulic cylinder, and a fixing plate is fixedly installed on one side of the hydraulic telescopic rod.

[0011] The bases on both sides of the top of the base plate cooperate with the slidingly installed V-blocks, which can be flexibly adjusted according to the length of the half-shaft sleeve to achieve stable clamping of the half-shaft sleeve, ensuring the stability of the half-shell during the positioning process and effectively avoiding assembly errors caused by inaccurate positioning. The hydraulic cylinder in the extrusion mechanism drives the fixing plate through the hydraulic telescopic rod, which can position and fix the various parts of the tooling.

[0012] As a preferred technical solution of this application, a bolt guard plate is fixedly installed on one side of the top surface of the V-block, and a leaf spring seat plate is movably snapped onto the top of the bolt guard plate. When installing the leaf spring seat plate, the bolt guard plate can effectively protect the connecting bolts from external impact and wear, extend the service life of the bolts, and ensure the stability of the connection between the leaf spring seat plate and the V-block. At the same time, the movable snapping method facilitates the quick installation and disassembly of the leaf spring seat plate.

[0013] As a preferred technical solution of this application, a motor mounting plate is fixedly installed on one side of the base surface, and a slide table is slidably installed inside the base. The bottom of the V-block is fixedly connected to the top of the slide table, which drives the slide table to slide and adjust on the top of the base. The connection between the slide table and the V-block allows the V-block to slide and adjust flexibly on the base. The position of the V-block can be quickly adjusted according to the different sizes of the half-shaft sleeve, so as to realize the positioning of half-shaft sleeves of different specifications and improve the adaptability of the tooling.

[0014] As a preferred technical solution of this application, a connecting rod is fixedly installed on the top of the V-block, a linkage rod is rotatably connected to one side of the connecting rod, an extrusion block is fixedly installed at the bottom of one side of the linkage rod, and a handle is fixedly installed on one side of the connecting rod. By operating the handle, the connecting rod can be rotated, and the extrusion block can be raised and lowered by the transmission of the linkage rod. The operator can flexibly control the clamping force between the extrusion block and the half-shaft sleeve according to actual needs, so as to further fix the half-shaft sleeve.

[0015] As a preferred technical solution of this application, one side of the surface of the fixing plate corresponds to the back of the half shell, and is clamped to the back of the half shell by means of a hydraulic cylinder and a hydraulic telescopic rod. The hydraulic cylinder drives the fixing plate through the hydraulic telescopic rod, and the clamping force and position can be flexibly adjusted according to the shape and size of the half shell to achieve stable clamping of the half shell.

[0016] As a preferred technical solution of this application, the bottom of the extrusion block is perpendicularly aligned with the top surface of the half-shaft sleeve, and is engaged with the top surface of the half-shaft sleeve by a linkage rod. When the extrusion block is engaged by descending, it can work together with the V-block from both the top and bottom to form a stable clamping structure, effectively preventing the half-shaft sleeve from shaking or shifting during positioning and assembly, and further improving the accuracy and stability of the half-shaft sleeve positioning.

[0017] As a preferred technical solution of this application, the bottom surface of the half-shaft sleeve is fixedly fastened to the top surface of the base plate by a V-block and bolt guard plate, and the back of the half-shell is fixedly fastened to the top surface of the base plate by a fixing plate. The V-block and bolt guard plate provide support and protection for the half-shaft sleeve from the bottom and sides, and the fixing plate fixes the half-shell from the back. Together, they form a stable overall positioning structure, which can effectively distribute the force during the assembly process and ensure that the half-shaft sleeve and the half-shell remain stable during positioning and assembly.

[0018] The base and V-block at the top of the base plate can be flexibly adjusted to precisely fit half-shaft sleeves of different lengths, ensuring stable positioning of the half-shell and reducing assembly errors. The hydraulic cylinder in the extrusion mechanism is linked to the hydraulic telescopic rod and the fixing plate, which can flexibly adjust the clamping force according to the shape and size of the half-shell, ensuring the reliability of the half-shell fixation. The extrusion block and V-block cooperate to build a stable clamping structure, enhancing the positioning stability of the half-shaft sleeve. The V-block, bolt guard plate and fixing plate cooperate with each other to form a stable three-dimensional positioning structure, effectively distributing the force and ensuring that the half-shaft sleeve and half-shell remain stable throughout the assembly process.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] This utility model provides a flexible positioning fixture for axle housing leaf spring in commercial vehicles, such as... Figure 1-5As shown, it includes a base plate 100 and an extrusion mechanism 200, which is fixedly installed at the center of the back of the base plate 100.

[0029] The base plate 100 has a base 101 fixedly installed on both sides of the top. A V-block 102 is slidably installed on the top of the base 101. A half-shaft sleeve 104 is fixedly snapped onto the top of the V-block 102. A half-shell 103 is fixedly connected to one side of the surface of the half-shaft sleeve 104.

[0030] The extrusion mechanism 200 includes a hydraulic cylinder 201, a hydraulic telescopic rod 202 is fixedly connected to one side of the surface of the hydraulic cylinder 201, and a fixing plate 203 is fixedly installed on one side of the surface of the hydraulic telescopic rod 202.

[0031] The bases 101 on both sides of the top of the base plate 100 cooperate with the slidingly installed V-blocks 102, which can be flexibly adjusted according to the length of the half-shaft sleeve 104 to achieve stable clamping of the half-shaft sleeve 104, ensuring the stability of the half-shell 103 during the positioning process, and effectively avoiding assembly errors caused by inaccurate positioning. The hydraulic cylinder 201 in the extrusion mechanism 200 drives the fixing plate 203 through the hydraulic telescopic rod 202, which can position and fix the various parts of the tooling.

[0032] like Figure 3 As shown, a bolt guard plate 107 is fixedly installed on one side of the top surface of the V-block 102. A leaf spring seat plate 108 is movably snapped onto the top of the bolt guard plate 107. When the leaf spring seat plate 108 is installed, the bolt guard plate 107 can effectively protect the connecting bolts from external impact and wear, extend the service life of the bolts, and ensure the stability of the connection between the leaf spring seat plate 108 and the V-block 102. At the same time, the movable snap-fit ​​method facilitates the quick installation and removal of the leaf spring seat plate 108.

[0033] like Figure 1-2 As shown, a motor mounting plate 105 is fixedly installed on one side of the base 101. A slide table 106 is slidably installed inside the base 101. The bottom of the V-block 102 is fixedly connected to the top of the slide table 106, which drives the slide table 106 to slide and adjust on the top of the base 101. The connection between the slide table 106 and the V-block 102 allows the V-block 102 to slide and adjust flexibly on the base 101. The position of the V-block 102 can be quickly adjusted according to the different sizes of the half-shaft sleeve 104, thereby achieving the positioning of half-shaft sleeves 104 of different specifications and improving the adaptability of the tooling.

[0034] like Figure 4As shown, a connecting rod 110 is fixedly installed on the top of the V-shaped block 102. A linkage rod 111 is rotatably connected to one side of the surface of the connecting rod 110. A pressing block 112 is fixedly installed at the bottom of one side of the surface of the linkage rod 111. A handle 109 is fixedly installed on one side of the surface of the connecting rod 110. By operating the handle 109, the connecting rod 110 can be rotated. Then, by using the transmission of the linkage rod 111, the pressing block 112 can be raised and lowered. The operator can flexibly control the clamping force between the pressing block 112 and the half-shaft sleeve 104 according to actual needs, so as to further fix the half-shaft sleeve 104.

[0035] like Figure 5 As shown, one side of the surface of the fixing plate 203 corresponds to the back of the half shell 103, and is clamped to the back of the half shell 103 by means of the hydraulic cylinder 201 and the hydraulic telescopic rod 202. The hydraulic cylinder 201 drives the fixing plate 203 through the hydraulic telescopic rod 202, and can flexibly adjust the clamping force and position according to the shape and size of the half shell 103 to achieve stable clamping of the half shell 103.

[0036] like Figure 2 and Figure 4 As shown, the bottom of the extrusion block 112 is perpendicular to the top surface of the half-shaft sleeve 104, and is engaged with the top surface of the half-shaft sleeve 104 by means of the linkage rod 111. When the extrusion block 112 is engaged, it can work together with the V-block 102 from both the top and bottom to form a stable clamping structure, which effectively prevents the half-shaft sleeve 104 from shaking or shifting during positioning and assembly, and further improves the accuracy and stability of the positioning of the half-shaft sleeve 104.

[0037] like Figure 2-3 As shown, the bottom surface of the half-shaft sleeve 104 is fixedly fastened to the top surface of the base plate 100 by the V-block 102 and the bolt guard plate 107, and the back of the half-shell 103 is fixedly fastened to the top surface of the base plate 100 by the fixing plate 203. The V-block 102 and the bolt guard plate 107 provide support and protection for the half-shaft sleeve 104 from the bottom and the side, and the fixing plate 203 fixes the half-shell 103 from the back. Together, they form a stable overall positioning structure, which can effectively distribute the force during the assembly process and ensure that the half-shaft sleeve 104 and the half-shell 103 remain stable during positioning and assembly.

[0038] In summary: First, based on the length of the half-shaft sleeve 104, the V-block 102 is slidably adjusted on the top of the base 101 by the slide table 106 inside the base 101, so that the V-block 102 adapts to the specifications of the half-shaft sleeve 104, completing the initial positioning and clamping; then, the top of the half-shaft sleeve 104 is fixedly snapped onto the V-block 102, and the half-shell 103 is connected to the half-shaft sleeve 104. At this time, the extrusion mechanism 200 is activated, and the hydraulic cylinder 201 pushes the hydraulic telescopic rod 202, driving the fixing plate 203 to move towards the back of the half-shell 103. The clamping force and position are adjusted according to the shape and size of the half-shell 103 to achieve a stable clamping of the half-shell 103. When installing the leaf spring seat plate 108, it is movably snapped onto the V-block 102. On the top bolt guard plate 107, the connecting bolts are protected and the installation and removal are facilitated. The operator holds the handle 109 and drives the connecting rod 110 to rotate. The linkage rod 111 drives the pressing block 112 to rise and fall. The clamping force between the pressing block 112 and the half-shaft sleeve 104 can be flexibly controlled according to actual needs. Together with the V-block 102, a stable clamping structure is formed from the top and bottom to prevent the half-shaft sleeve 104 from shaking or displacing. Finally, the bottom of the half-shaft sleeve 104 is supported and protected by the V-block 102 and the bolt guard plate 107, and the back of the half-shell 103 is fixed by the fixing plate 203. All components cooperate with each other to form a stable overall positioning structure, effectively distributing the force and ensuring the stability of the commercial vehicle axle shell leaf spring during positioning and assembly.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
