Description

Technical Field

[0001] This utility model belongs to the field of disassembly tooling technology, and specifically relates to a disassembly tooling. Background Technology

[0002] In existing technologies, the separation of the front suspension cylinder from the front wheel assembly is generally achieved by pushing the cylinder head upwards or pulling the wheel assembly downwards. Because the cylinder head can move up and down, the cylinder head must be at its limit position before the wheel assembly can be separated. Since the wheel assembly is suspended by the cylinder, a jack is needed to continuously raise the height of the jack when pushing it upwards, and the wheel assembly needs to be pulled downwards to ensure a stable descent. Both methods require constant adjustment of the tooling height during disassembly, which presents difficulties in disassembling the front suspension cylinder from the wheel assembly.

[0017] Explanation of reference numerals in the attached figures Detailed Implementation

[0018] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0019] The disassembly fixture according to this utility model is described below with reference to the accompanying drawings.

[0020] like Figure 1 , Figure 2 and Figure 4 As shown, in this embodiment, a disassembly fixture is proposed. This disassembly fixture is used to separate the front suspension cylinder 10 and the front wheel assembly 20. The front wheel assembly 20 has an insertion hole 201 for the piston rod 101 of the front suspension cylinder 10 to be inserted. The disassembly fixture includes a fixture plate assembly 1 and a locking member 2. The fixture plate assembly 1 abuts against the end of the piston rod 101. The locking member 2 is used to drive the fixture plate assembly 1 to move towards the front wheel assembly 20 and lock the fixture plate assembly 1 and the front wheel assembly 20. During the locking process, a supporting force is applied to the piston rod 101 through the fixture plate assembly 1, causing the piston rod 101 to separate from the insertion hole 201. Thus, the front suspension cylinder 10 can be separated from the front wheel assembly 20, solving the technical problem of inconvenient disassembly and reassembly of the front suspension cylinder 10 and the front wheel assembly 20 in the prior art.

[0021] In addition, the front wheel assembly 20 also includes a mounting plate. A limiting hole for inserting the mounting plate is provided at the bottom of the front wheel assembly 20. The limiting hole communicates with the insertion hole 201, and the diameter of the limiting hole is larger than the diameter of the insertion hole 201. The mounting plate is used to detachably connect the piston rod 101 to the front wheel assembly 20. When it is necessary to separate the piston rod 101 from the insertion hole 201 using a disassembly tool, the mounting plate must be removed first to avoid affecting the supporting force applied to the piston rod 101 by the tooling plate assembly 1. In existing technologies, when using tools such as jacks for disassembly, a platform needs to be placed underneath to elevate the jack, requiring a relatively large working space. However, the tooling plate assembly 1 of the disassembly tooling of this application can directly abut against the piston rod 101. The disassembly tooling of this application requires less working space and is more convenient to use.

[0022] like Figure 1As shown, in this embodiment, the bottom of the front wheel assembly 20 is provided with a plurality of mounting holes arranged circumferentially. The tooling plate assembly 1 includes a tooling plate 11 and a protrusion 12 provided on the tooling plate 11. The protrusion 12 is inserted into the insertion hole 201 from the end opposite to the piston rod 101 and abuts against the end of the piston rod 101 to efficiently apply a supporting force to the piston rod 101. The tooling plate 11 is also provided with positioning holes 111. There are multiple positioning holes 111, and they are arranged one by one corresponding to the mounting holes. The locking member 2 is used to connect the multiple positioning holes 111 to the mounting holes one by one to lock the tooling plate 11 and the front wheel assembly 20. It should be noted that the multiple mounting holes provided at the bottom of the front wheel assembly 20 are used to install the steering knuckle arm 30. The steering knuckle arm 30 can be detachably connected to the front wheel assembly 20 by bolts. When it is necessary to separate the piston rod 101 from the insertion hole 201 using the disassembly fixture, the steering knuckle arm 30 must first be removed from the front wheel assembly 20 and the bolts removed to avoid affecting the assembly of the disassembly fixture with the front wheel assembly 20. If the steering knuckle arm 30 is not removed, since the steering knuckle arm 30 has a certain thickness, the dimensions of the locking part 2 and the protrusion 12 need to be adjusted accordingly to ensure that the disassembly fixture can efficiently separate the front suspension cylinder 10 and the front wheel assembly 20.

[0023] like Figure 1 and Figure 3 As shown, in this embodiment, the outer diameter of the piston rod 101 gradually decreases towards the front wheel assembly 20. The inner diameter of the insertion hole 201 is greater than the minimum outer diameter of the piston rod 101 but less than the maximum outer diameter of the piston rod 101, ensuring that a portion of the piston rod 101 can be located outside the insertion hole 201. The protrusion 12 has a cylindrical structure, and its outer diameter is less than or equal to the end outer diameter of the piston rod 101. When the outer diameter of the protrusion 12 is equal to the end outer diameter of the piston rod 101, the supporting effect is optimal, stably driving the piston rod 101 upward.

[0024] like Figure 4 As shown, in this embodiment, multiple positioning holes 111 are all opened on the tooling plate 11 and are arranged at equal intervals around the protrusion 12, resulting in good installation stability.

[0025] Furthermore, in this embodiment, the mounting hole has an internal thread, and the outer peripheral wall of the locking member 2 has an external thread adapted to the internal thread. The locking member 2 passes through the positioning hole 111 and the mounting hole in sequence to lock the tooling disc 11 onto the front wheel assembly 20. In this application, the tooling is fixed onto the front wheel assembly 20 by using a threaded connection, which can further improve the installation stability of the tooling disc 11. The locking member 2 is a bolt. By applying a uniform torque to the bolt, the separation of the front wheel assembly 20 from the front suspension cylinder 10 can be made smoother, reducing vibration during separation.

[0026] In this embodiment, the diameter of the positioning hole 111 is larger than the diameter of the mounting hole, which can effectively reduce the accuracy required for machining the tooling disc 11 and ensure that the locking member 2 can stably pass through the positioning hole 111 and the mounting hole in sequence.

[0027] like Figure 4 and Figure 5 As shown, in this embodiment, an observation port 112 is provided in the middle of the tooling tray 11, and a weight reduction notch 121 is provided in the middle of the protrusion 12, which can effectively reduce the overall weight of the tooling tray assembly 1. The diameter of the weight reduction notch 121 is larger than the diameter of the observation port 112, and the weight reduction notch 121 is connected to the observation port 112.

[0028] like Figure 1 and Figure 5 As shown, in this embodiment, there are multiple locking components 2, and these multiple locking components 2 are arranged symmetrically about the center of the tooling plate 11, resulting in good installation stability. The number of locking components 2 used to lock the disassembly tooling to the front wheel assembly 20 can be adjusted according to actual needs. It is not necessary for each positioning hole 111 to have a corresponding locking component 2 inserted, as this would lead to cumbersome operation.

[0029] like Figure 4 and Figure 5 As shown, in this embodiment, the protrusion 12 is coaxially arranged with the tooling plate 11, and the top support has good stability, which can ensure that the piston rod 101 moves upward from the insertion hole 201 under the support of the protrusion 12 and eventually separates from the insertion hole 201. The disassembly tooling structure of this application is simple and highly practical.

[0030] In this embodiment, the height of the protrusion 12 ranges from 150mm to 180mm. Preferably, the height of the protrusion 12 is set to 150mm, which allows the piston rod 101 to be pushed upwards, thus ensuring that the piston rod 101 can be separated from the insertion hole 201. The height of the protrusion 12 can be adjusted according to actual needs.
