Description

Technical Field

[0001] The invention relates to an auxiliary tool, in particular to an automatic gearbox assembly auxiliary tool. Background Art

[0002] As the light truck market becomes younger, more high-end, and more intelligent, users have higher and higher requirements for driving comfort, and automatic transmission has gradually expanded from passenger cars to light trucks. However, during the assembly of the automatic transmission of a light truck and the engine, the TCU cannot push the shift actuator to engage the forward gear because it cannot be connected to an external air source and power source. The first shaft of the transmission can rotate freely during the assembly process, and it cannot be assembled with the gear locked like a manual transmission. Therefore, the assembly of the automatic transmission of a light truck is very difficult, which seriously affects production efficiency.

[0003] In the prior art, the method to solve the above problem is to increase the chamfer of the spline of the first shaft of the automatic transmission, so that the spline shaft and the engine clutch spline sleeve are more accurately positioned during assembly, making it easier for the spline of the first shaft of the automatic transmission to be inserted into the engine. However, the chamfer of the spline of the first shaft of the automatic transmission is increased, and the first shaft needs to be redesigned and molded, and there are many types involved, which is costly; after the automatic transmission is assembled, the clutch spline sleeve is matched with the spline shaft of the first shaft, but the chamfer of the front end of the spline shaft of the first shaft is too long, and the clutch spline sleeve will be suspended, which will cause abnormal clutch noise; during the assembly process of the automatic transmission, the first shaft can still rotate freely, and the problem of difficult assembly is slightly improved, but it cannot be completely solved. Summary of the invention

[0013] Figure 1 It is a structural schematic diagram of the present invention.

[0014] Description of the accompanying drawings: handle 1, connecting rod 2, claw 3, adjusting cross bar 4, locking bolt 5, connecting piece 6, upper positioning boss 7, lower positioning boss 8, threaded hole 9. DETAILED DESCRIPTION

[0015] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be interpreted as limiting the present invention.

[0016] Embodiments of the present invention: Figure 1As shown, an automatic transmission assembly aid includes a handle 1, a connecting rod 2, a claw 3 and a claw angle adjustment mechanism, one end of the connecting rod 2 is connected to the handle 1, and the other end of the connecting rod 2 is rotatably mounted with two claws 3, the claw angle adjustment mechanism is movably mounted on the connecting rod 2, the claw angle adjustment mechanism is also connected to the two claws 3, and the two claws 3 are symmetrically arranged relative to the axis of the connecting rod 2.

[0017] The length of the handle 1 can be selected according to the vehicle model and the requirements. After selecting a handle 1 of a suitable length, connect it to the connecting rod 2, and then separate the two claws 3 from each other through the claw angle adjustment mechanism, even if the opening between the two becomes larger, and then move to one axis, and then use the claw angle adjustment mechanism to clamp the two claws 3 to clamp the one axis. At this time, when installing the automatic transmission, the one axis can be controlled not to rotate, so as to achieve rapid assembly. The technical solution of the present invention does not require modification of one axis, and since the openings of the two claws 3 are adjustable, the present invention is applicable to various vehicle models, and completely solves the problem of one axis rotating when assembling the automatic transmission. In addition, the present invention has a simple structure, low manufacturing cost, and is suitable for popularization and application.

[0018] In a specific embodiment, the connecting rod 2 is a square rod, that is, the cross-section of the connecting rod 2 is square, and the connecting rod 2 is threadedly connected to the handle 1. Designing the connecting rod 2 as a square rod allows the claw angle adjustment mechanism to move only in the axial direction when moving on the connecting rod 2 without generating circumferential rotation, which is convenient for adjustment and control.

[0019] Furthermore, the claw angle adjustment mechanism includes an adjusting cross bar 4 and a connecting piece 6. The adjusting cross bar 4 is perpendicular to the connecting rod 2. A square hole is opened in the middle position of the adjusting cross bar 4. The adjusting cross bar 4 slides with the connecting rod 2 through the square hole. A connecting piece 6 is installed at each end of the adjusting cross bar 4. The two connecting pieces 6 are respectively connected to the two claws 3.

[0020] The connecting member 6 can be a spring or a connecting rod. When a spring is used, one end of the spring is fixedly connected to the end of the adjusting cross bar 4, and the other end of the spring is fixedly connected to the claw 3; when a connecting rod is used, one end of the connecting rod is rotatably connected to the adjusting cross bar 4, and the other end of the connecting rod is rotatably connected to the claw 3. Since the connecting rod connection requires the provision of connecting ear plates on the adjusting cross bar 4 and the claw 3, the processing procedure is complicated, so the spring solution is preferably used in this case.

[0021] Furthermore, an upper positioning boss 7 and a lower positioning boss 8 are provided on the connecting rod 2, and the adjusting cross bar 4 is located between the upper positioning boss 7 and the lower positioning boss 8. The upper positioning boss 7 and the lower positioning boss 8 are provided to limit the movable range of the adjusting cross bar 4. If the adjusting cross bar 4 is too close to the claw 3, the holding force between the two claws 3 will be too large, which will damage the spline of one shaft. If the adjusting cross bar 4 is too far away from the claw 3, the two claws 3 will be overturned, and the angle of the claw 3 needs to be adjusted manually, which affects the assembly efficiency. Therefore, the upper positioning boss 7 and the lower positioning boss 8 are provided to enable the adjusting cross bar 4 to move within a reasonable range.

[0022] Furthermore, a locking bolt 5 is included, and a threaded hole 9 is formed at one end of the adjusting cross bar 4, the threaded hole 9 is connected to the square hole, and the locking bolt 5 is threadedly connected to the threaded hole 9. When the adjusting cross bar 4 is adjusted to a suitable position, the adjusting cross bar 4 is fixed to the connecting rod 2 by rotating the locking bolt 5, so as to realize continuous clamping of one shaft. When the assembly work is completed, the locking bolt 5 is loosened to open the two claws 3.

[0023] The method of using the present invention is as follows: when using, select a handle 1 of a suitable length according to the vehicle model, then fix the handle 1 to the connecting rod 2, then pull the adjusting cross bar 4 backward, the two claws 3 open, move the two claws 3 to an axis, and then push the adjusting cross bar 4. The connecting pieces 6 (springs) at both ends of the adjusting cross bar 4 push the two claws 3 to clamp the one axis. Under the thrust of the spring, the two claws 3 can clamp the one axis well, and then tighten the locking bolt 5. The end of the locking bolt 5 abuts against the connecting rod 2 to position the adjusting cross bar 4 on the connecting rod 2. At this time, the adjusting cross bar 4 cannot be displaced relative to the connecting rod 2. Then hold the handle 1 to keep the one axis from rotating. Another staff member is responsible for assembling the automatic transmission. When the one axis is half inserted into the engine, loosen the locking bolt 5, pull the adjusting cross bar 4, and the two claws 3 release the one axis. At this time, the subsequent assembly work of the automatic transmission can be continued.

[0024] The above describes in detail the structure, features and effects of the present invention based on the embodiments shown in the drawings. The above is only a preferred embodiment of the present invention, but the present invention is not limited to the scope of implementation shown in the drawings. Any changes made according to the concept of the present invention, or modifications to equivalent embodiments with equivalent changes, which still do not exceed the spirit covered by the description and drawings, should be within the protection scope of the present invention.
