Description

Technical Field

[0001] The present invention relates to the technical field of automatic transmission reconstruction, and particularly to a transmission component installation tool and its usage method. Background Art

[0002] The left half shaft is a component of an automatic transmission. One end of the left half shaft supports a flange through a bearing. During the reconstruction of the transmission, it is necessary to install the bearing between the shaft hole of the flange and the left half shaft to rotatably connect the flange to the left half shaft. During the installation of the bearing, the bearing can only be installed from the end of the left half shaft far from the separation. The existing method for installing the bearing of the left half shaft flange is to use a hammer to change the knocking position along the circumference of the bearing to drive the bearing to move axially along the left half shaft. Due to the small thickness of the bearing and the interference of the half shaft, it is very inconvenient to install the bearing and the installation speed is slow. Moreover, this local knocking method is likely to cause damage to the bearing surface.

[0003] The known method is to nest a pipe on the half shaft, and then manually hold one end of the pipe and push the pipe forward to impact the bearing, so that the bearing is in interference fit with the flange and the half shaft. However, this method requires manually pulling the pipe backward and then pushing the pipe forward to impact the bearing. The arm needs to reciprocate once before and after to complete one impact on the bearing, and the force of the arm driving the pipe to move backward is not utilized at all, resulting in low efficiency of installing the bearing. Summary of the Invention

[0004] Therefore, the present invention is made in view of the above problems. The purpose of the present invention is to provide a transmission component installation tool and method, and the present invention solves the above problems through the following technical solutions.

[0005] A transmission component installation tool includes: a housing, a pipe, a handle, a connecting rod, a connecting plate, and a baffle;

[0006] One end of the housing is provided with a first impact portion. Opposite inner wall surfaces of the housing are provided with strip-shaped slideways one, and springs are respectively arranged in two strip-shaped grooves one, wherein the first impact portion is communicated with one side wall surface of the housing;

[0007] The pipe is arranged inside the housing, and the axis of the pipe is on the same straight line as that of the first impact portion. The diameter of the pipe is smaller than that of the first impact portion, and the pipe is slidably connected to the housing;

[0008] Opposite inner wall surfaces on both sides of the middle part of the pipe are provided with strip-shaped grooves two. The pipe is axially provided with a strip-shaped notch, and one end of the pipe facing the first impact portion is a second impact portion;

[0009] The end surfaces of the second impact portion and the first impact portion are flush initially;

[0010] The length, extension direction of the second strip-shaped groove are the same as those of the first strip-shaped groove;

[0011] The handle is fixed on one side wall of the housing, and the handle forms a ninety-degree angle with the pipeline;

[0012] The number of the connecting rods is two. The two connecting rods are oppositely arranged inside the housing. Three shafts 41 are fixedly arranged straight on the connecting rods. The three shafts are respectively located at both ends and the middle of the connecting rod. The shaft in the middle of the connecting rod is located above the pipeline;

[0013] The two connecting rods are located on both sides of the pipeline. The shafts at one ends of the two connecting rods are connected to the second strip-shaped groove, and the shafts at the other ends of the two connecting rods are connected to the first strip-shaped groove;

[0014] The number of the connecting plates is two. The two connecting plates are axially connected to the shafts in the middle of the two connecting rods. Two symmetrical slideways are arranged on the wall surface of the connecting plates;

[0015] The baffle is composed of a first plate, sliding blocks and a second plate. The first plate is located between the two connecting plates. The number of the sliding blocks is four. The sliding blocks are fixedly arranged in pairs on both sides of the first plate and inserted into the slideways on both sides. The number of the second plates is two. One ends of the two second plates are respectively fixed on the side wall surfaces of the first plate where the sliding blocks are arranged at an angle.

[0034] As Figure 3 As shown, the number of the connecting rods 4 is two, and the two connecting rods 4 are oppositely arranged inside the housing 1. Three shafts 41 are fixedly arranged straight on the connecting rod 4, and the three shafts 41 are respectively located at both ends and the middle of the connecting rod 4. Among them, the shaft 41 in the middle of the connecting rod 4 is located above the pipe 2;

[0035] The two connecting rods 4 are located on both sides of the pipe 2, and the shafts 41 at one ends of the two connecting rods 4 are connected to the second strip-shaped groove 22, and the shafts 41 at the other ends of the two connecting rods 4 are connected to the first strip-shaped groove 12.
