Description

Technical Field

[0001] This utility model relates to the field of vehicle maintenance technology, specifically to an auxiliary tooling and system for disassembling a drive shaft ten-byte assembly. Background Technology

[0002] During vehicle maintenance, old drive shafts are often damaged due to lack of lubrication or excessive wear of the tenon sleeve needle rollers. Old drive shafts can be reused by disassembling, cleaning, replacing the tenon sleeves, and repairing them, thus having extremely high repair and reuse value.

[0003] During the repair of vehicle drive shafts, it is necessary to disassemble the universal joint. Currently, the traditional disassembly method mainly involves using a hammer to strike the universal joint fork to vibrate the cross shaft, and finally prying open the bearing cover to remove the universal joint. This method is time-consuming and labor-intensive. In addition, prolonged hammering of the universal joint can easily cause mechanical damage to the parts and has low disassembly efficiency.

[0004] Based on the above background, the inventors designed a disassembly auxiliary tooling and system for a transmission shaft ten-byte structure, which solves at least one of the above problems, and thus, this application is filed. Summary of the Invention

[0005] The purpose of this application is to provide an auxiliary tooling and system for disassembling a universal joint of a drive shaft, in order to solve the problem that in the prior art, the universal joint of a drive shaft is disassembled by hitting it with a hammer, which not only easily causes mechanical damage to the parts, but also has low disassembly efficiency.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following solution:

[0007] On the one hand, this application provides a disassembly auxiliary tooling for a drive shaft ten-piece, including a base plate and a first support plate and a second support plate disposed on the base plate, wherein there is a gap between the first support plate and the second support plate for cooperating with a top pressure sleeve to disengage one end of the ten-piece sleeve from the ten-piece body;

[0008] The top of the first support plate and the second support plate are respectively provided with a first support recess and a second support recess for suspending two horizontal sections of the ten-byte main body.

[0009] The first support recess and the second support recess have the same structure and are at the same height.

[0010] Optionally, both the first support recess and the second support recess are C-shaped with their openings facing upwards.

[0011] Optionally, both the first support plate and the second support plate are L-shaped.

[0012] Optionally, it also includes a reinforcing plate fixed to the first support plate and the second support plate, both of which are perpendicular to each other.

[0013] Optionally, the first support plate is detachably fixed to the base plate, and the second support plate is welded to the base plate.

[0014] Optionally, the first support plate is provided with strip-shaped adjustment holes;

[0015] It also includes fasteners, with the first support plate being detachably connected to the base plate via fasteners installed through a through-strip adjustment hole.

[0016] Optionally, the fastener is a fastening bolt or a fastening screw.

[0017] On the other hand, this application provides a disassembly system for a drive shaft ten-piece, including any of the above-described auxiliary tooling for disassembling a drive shaft ten-piece, a top-pressure sleeve for fitting onto the ten-piece body and pushing the ten-piece sleeve, and a hydraulic pushing device, the output end of which is a hydraulic push rod vertically arranged above the first support plate and the second support plate.

[0018] Beneficial effects of the utility model:

[0019] This application sets up a base plate and a first support plate and a second support plate on the base plate, with a gap between the first support plate and the second support plate. The top of the first support plate and the second support plate are respectively provided with a first support recess and a second support recess, so that the universal joint can be placed on the first support recess and the second support recess. At this time, the top pressure sleeve is then put on the universal joint, and then the top pressure sleeve is pushed by a hydraulic jacking device, so that the universal joint sleeve on the universal joint body can be separated from it, thereby removing the universal joint body from the universal joint sleeve. This can effectively solve the problem that in the prior art, the universal joint of the drive shaft is removed by hitting it with a hammer, which not only easily causes mechanical damage to the parts, but also has low disassembly efficiency.

[0028] Example 1:

[0029] like Figure 1 As shown, this embodiment provides a disassembly auxiliary tooling for a drive shaft ten-piece, including a base plate 1 and a first support plate 2 and a second support plate 3 disposed on the base plate 1. The first support plate 2 and the second support plate 3 have a gap between them for cooperating with the top pressure sleeve 8 so that one end of the ten-piece sleeve 7 is disengaged from the ten-piece body 6.

[0030] The top of the first support plate 2 and the second support plate 3 are respectively provided with a first support recess 201 and a second support recess 301 for suspending two horizontal sections of the ten-byte main body 6.

[0031] The first support recess 201 and the second support recess 301 have the same structure and are at the same height.

[0032] This embodiment sets up a base plate 1 and a first support plate 2 and a second support plate 3 on the base plate 1. The first support plate 2 and the second support plate 3 have a gap between them. The top of the first support plate 2 and the second support plate 3 are respectively provided with a first support recess 201 and a second support recess 301, so that the universal joint can be placed on the first support recess 201 and the second support recess 301. At this time, the top pressure sleeve 8 is then fitted onto the universal joint. Then, the top pressure sleeve 8 is pushed by a hydraulic jacking device, so that the universal joint sleeve 7 on the universal joint body 6 can be separated from it. Thus, the universal joint body 6 can be disassembled from the universal joint sleeve 7. This can effectively solve the problem that in the prior art, when disassembling the universal joint of the drive shaft, it is necessary to knock it out with a hammer, which not only easily causes mechanical damage to the parts, but also has low disassembly efficiency.

[0033] In this embodiment, as Figure 1 As shown, the first support recess 201 and the second support recess 301 are both C-shaped with the opening facing upwards. In some embodiments, those skilled in the art may also set the shapes of the first support recess 201 and the second support recess 301 to other shapes, such as V-shaped or U-shaped.

[0034] In this embodiment, as Figure 1 As shown, both the first support plate 2 and the second support plate 3 are L-shaped. In some embodiments, the first support plate 2 and the second support plate 3 may also adopt other shapes, such as an inverted T-shape.

[0035] In this embodiment, as Figure 1 As shown, it also includes a reinforcing plate 4 fixed to the first support plate 2 and the second support plate 3, with both the first support plate 2 and the second support plate 3 perpendicular to each other. The reinforcing plate 4 improves the structural strength of the first support plate 2 and the second support plate 3.

[0036] In this embodiment, the first support plate 2 is detachably fixedly connected to the base plate 1, and the second support plate 3 is welded and fixed to the base plate 1. The detachable connection between the first support plate 2 and the base plate 1 allows the spacing between the first support plate 2 and the second support plate 3 to be adjustable, thereby enabling the tooling of this embodiment to be applicable to the disassembly of various types of ten-byte components.

[0037] In this embodiment, the first support plate 2 is provided with a strip-shaped adjustment hole 202;

[0038] It also includes fasteners. The first support plate 2 is detachably connected to the base plate 1 via fasteners that pass through the strip-shaped adjustment holes 202. In this embodiment, the base plate 1 is provided with through holes that are compatible with the fasteners, and two strip-shaped adjustment holes 202 are provided on both sides of the reinforcing plate 4 of the first support plate 2, so that the stability is better when the first support plate 2 is connected to the base plate 1.

[0039] In this embodiment, the fastener is a fastening bolt; in some embodiments, the fastener may also be a fastening screw.

[0040] Example 2:

[0041] like Figure 2 and Figure 3 As shown, this embodiment provides a disassembly system for a drive shaft ten-piece, including any of the above-described auxiliary tooling for disassembling a drive shaft ten-piece, a pressing sleeve 8 for mounting on the ten-piece body 6 and pushing the ten-piece sleeve 7, and a hydraulic pushing device, the output end of which is a hydraulic push rod 9 vertically arranged above the first support plate 2 and the second support plate 3.

[0042] In this embodiment, the top pressure sleeve 8 is a rigid sleeve, which can be made of steel to ensure the structural stability of the top pressure sleeve 8. The rest of the structure in this embodiment is the same as that in Embodiment 1 above, and will not be described again here.

[0043] The hydraulic jacking device in this embodiment is an existing device and will not be described in detail here.

[0044] It is understood that the above embodiments are merely exemplary implementations used to illustrate the principles of this utility model, and the utility model is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of this utility model, and these modifications and improvements are also considered to be within the protection scope of this utility model.
