Description

Technical Field

[0001] The present invention relates to the technical field of automatic transmission reconstruction, and particularly to a tool for installing transmission components. 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 away from the separation. The existing method for installing the bearing of the left half shaft flange is to use a hammer to drive the bearing to move axially along the left half shaft by changing the knocking position along the circumference of the bearing. 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 tube on the half shaft, and then an artificial hand holds one end of the tube and pushes the tube forward to impact the bearing, so that the bearing is in interference fit with the flange and the half shaft. However, this method requires the artificial hand to pull the tube backward and then push the tube forward to impact the bearing. When pulling the tube backward, the arm can be extended, which is beneficial for applying force. But when pushing the tube forward, the arm cannot be fully extended, so it is not easy to apply force, which is not conducive to the impact strength on the bearing, thus affecting the efficiency of installing the bearing.

[0004] When the bearing and the half shaft are not in interference fit, the inner diameter of the bearing is larger than the diameter of one end of the half shaft, resulting in the inner diameter of the upper end of the bearing being in contact with the top surface of the half shaft. Therefore, the bearing and the half shaft are not coaxial during the first impact, which is not conducive to the impact of the tube on the bearing. On the one hand, when impacting the bearing, it is impossible to apply force to the bearing well. On the other hand, the tube and the bearing are not coaxial. When the tube impacts the bearing, due to uneven force, the bearing is easily damaged. Summary of the Invention

[0005] Therefore, the present invention is made in view of the above problems. The purpose of the present invention is to provide a tool for installing transmission components, and the present invention solves the above problems through the following technical solutions.

[0008] The impact plate is a half-round tube, and the number is two. The openings are arranged oppositely. The two impact plates are arranged inside the tube. Among them, slider I is respectively provided on the two impact plates, and strip-shaped through opening II is provided at one end of the two impact plates, and shaft II is provided at the other end;

[0009] A block is provided at the extended end of the second shaft, and the width of the block is greater than that of the second shaft;

[0014] The number and shape of the second plates are the same as those of the first plates. The second plates are connected to the connecting rings by inserting bumps into the chutes. There is a certain distance between the two second plates and the two first plates;

[0015] Strip-shaped grooves are respectively formed on the walls of the first plates and the second plates. The strip-shaped grooves are inclined, and the inclination directions of the strip-shaped grooves on the first plates and the second plates are the same;

[0016] The two first shafts and the two second shafts are respectively connected in the strip-shaped grooves of the two first plates and the two second plates. The connection directions of the first shafts and the second shafts to the strip-shaped grooves are opposite;

[0017] The number of the baffles is four. Two of them are fixed on the walls of the two second plates facing the axis of the connecting ring. The distance between the two baffles on a single second plate is the same as the length of the large-diameter end of the half shaft;

[0018] The clamping assembly includes: a clamping plate, a spring, a second slider, and a resisting rod;

[0019] The clamping plates are arc-shaped plates, and the number is two and they are arranged oppositely. The number of the springs is the same as that of the clamping plates.

[0023] In the present invention, the bearing is clamped by the clamping plate. During the first impact, on the one hand, it avoids the situation where it is impossible to apply force to the bearing well when impacting the bearing, and on the other hand, it avoids the misalignment between the first sleeve and the bearing. When the first sleeve impacts the bearing, due to uneven force, it is easy to damage the bearing. Description of the Drawings

[0034] As Figure 1-2 shown, the transmission component installation tool includes: a tube 1, an impact plate 2, a transmission component 3, a clamping component 4, and a handle 5;

[0035] One end of the tube 1 is closed. Bar-shaped through openings 11 are respectively provided on the opposite walls of the tube 1. Inside the tube 1, two shafts 12 extending towards the axis of the tube 1 are provided at the closed end.

[0036] The impact plate 2 is a half-round tube, and there are two of them. The openings are arranged opposite to each other. The two impact plates 2 are arranged inside the tube 1. Sliders 21 are respectively provided on the two impact plates 2. A bar-shaped through opening 22 is provided at one end of the two impact plates 2, and a shaft 23 is provided at the other end.

[0037] A block 231 is provided at the extending end of the shaft 23, and the width of the block 231 is greater than that of the shaft 23.

[0038] The slider 21 is connected to the bar-shaped through opening 11. The impact plate 2 can move in the X-axis and Y-axis directions inside the tube 1 through the slider 21.

[0039] As Figure 3 、 5 shown, the transmission component 3 includes: a connecting ring 31, a plate 32, a plate 33, a bar-shaped groove 34, and a baffle 35;

[0040] There are two connecting rings 31. The two connecting rings 31 are coaxially arranged, and the inner diameters of the two connecting rings 31 are the same as the diameter of the large-diameter section 61 of the half shaft 6.

[0041] Chute grooves 311 are respectively provided at the opposite ends of the connecting ring 31.

[0042] The plate 32 is an arc-shaped plate, and there are two of them. The recessed parts of the two plates 32 are fixedly arranged between the two connecting rings 31 in opposite directions. The angle between the two plates 32 and the chute groove 311 is 90 degrees.

[0043] The number and shape of the plate 33 are the same as those of the plate 32. The recessed parts of the two plates 33 are opposite to each other. The two plates 33 are arranged on the connecting ring 31 by inserting convex blocks into the chute grooves 311. There is a certain distance between the two plates 33 and the two plates 32.

[0044] Strip-shaped grooves 34 are respectively formed on the arc-shaped wall surfaces of the first plate 32 and the second plate 33;

[0045] The strip-shaped grooves 34 are inclined, and the strip-shaped grooves 34 on the first plate 32 and the second plate 33 have the same inclination direction. As Figure 4 shown, the height of the strip-shaped groove 34 formed on the second plate 33 on the side away from the closed end of the pipe 1 is greater than that of the remaining parts;

[0046] The two first shafts 12 are respectively connected in the strip-shaped grooves 34 of the two first plates 32, and the two second shafts 23 are respectively connected in the strip-shaped grooves 34 of the two second plates 33, wherein the directions of the first shaft 12 and the second shaft 2 connecting the strip-shaped grooves 34 are opposite;

[0047] The number of the baffle plates 35 is four, and they are fixed in pairs on the arc surfaces of the recessed parts of the two second plates 33, and the four baffle plates 35 extend towards the axis of the connecting ring 31. As Figure 5 shown, the distance between the two baffle plates 35 on a single second plate 33 is the same as the length of the large diameter end 61 of the semi-axis 6;

[0048] As Figure 6 shown, the clamping assembly 4 includes: a clamping plate 41, a spring 42, a second slider 43, and a resisting rod 44;

[0049] The clamping plate 41 is an arc-shaped plate, and the number of the clamping plates 41 is two and they are arranged oppositely. The two clamping plates 41 jointly clamp the bearing 7;

[0050] The number of the springs 42 is the same as that of the clamping plates 41. The two springs 42 are respectively located on one side of the two opposite ends of the two clamping plates 41, and the two ends of the spring 42 are respectively connected to the two clamping plates 41. Initially, the opposite end faces of the two clamping plates 41 are attached to form a ring, and the inner diameter of the ring formed by the two clamping plates 41 is smaller than that of the bearing 7;

[0051] The number of the second sliders 43 is the same as that of the clamping plates 41. They are respectively fixed on the two clamping plates 41 and are connected to the strip-shaped through holes two 22 of the two impact plates 2;

[0052] As Figure 7 shown, the second slider 43 is composed of two strip-shaped plates connected by a rod. One of the strip-shaped plates of the second slider 43 fits the recessed wall surface of the impact plate 2, and the other strip-shaped plate fits the raised wall surface of the impact plate 2. The rod of the second slider 43 is in the strip-shaped through hole two 22. When the bearing 7 is placed into the ring formed by the two clamping plates 41, the bearing 7 separates the two clamping plates 41. At the same time, the two strip-shaped plates of the second slider 43 pull the two impact plates 2 away. The two impact plates 2 move, and the second shaft 23 follows the movement. The block 231 at the extending end of the second shaft 23 abuts against the side with a greater height of the strip-shaped groove 34 and pulls the two second plates 33 away. At this time, the distance between the relative baffle plates 35 of the two second plates 33 is greater than the diameter of the large diameter section 61 of the semi-axis 6;

[0053] One end of the abutting rod 44 is fixed to the clamping plate 41, and the other end extends forward, wherein the extending length of the abutting rod 44 is the same as the moving distance of the bearing 7 in interference fit on the half shaft 6;

[0054] One end of the handle 5 is connected to the closed end of the tube 1.

[0055] The working principle of the present invention:

[0056] First, pull the impact plate 2 and the clamping assembly 4 along the strip through hole one 11 and the strip through hole two 22 to the ends of the strip through hole one 11 and the strip through hole two 22. Then, place the bearing 7 into the ring formed by the two clamping plates 41. The bearing 7 separates the two clamping plates 41. At the same time, the two strip plates of the slider two 43 pull the two impact plates 2 away. The two impact plates 2 move, and the shaft two 23 follows the movement. The block 231 at the extending end of the shaft two 233 abuts against the side with a larger height of the strip groove 34 and pulls the two plate twos 33 away. At this time, the block 231 is engaged with the strip groove 34, and the impact plate 2 cannot move. As Figure 8 shown, hold the handle 5 and push it forward. The two impact plates 2 are nested on one end of the half shaft 6 to perform interference connection on the bearing 7 until the end face of the half shaft 6 is attached to the closed end of the tube 1. At this time, the abutting rod 44 impacts the wall surface of the flange 8, and the abutting rod 44 drives the clamping plate 41 to move backward. The two clamping plates 41 are separated from the bearing 7 and recombine into a ring. At the same time, the two strip plates of the slider two 43 push the two impact plates 2 closer. The block 231 at the extending end of the shaft two 233 abuts against the two plate twos 33 to move closer, so that the four baffles 35 are nested on the large diameter section 61 of the half shaft 6. The transmission assembly 3 is connected to the large diameter section 61 of the half shaft 6. Pull back the tube 1. When the tube 1 moves, it moves through the shaft one 12 in the strip groove 34, driving the plate two 33 to rotate. When the plate two 33 rotates, it pushes the shaft two 23 through the strip groove 34, so that the two impact plates 2 move forward and impact the bearing 7. By reciprocating the movement of the tube 1, the impact plate 2 impacts the bearing 7, enabling the bearing 7 to achieve interference connection with the half shaft 6 and the flange 8.
