Description

Technical Field

[0001] The present invention belongs to the technical field of automotive transmission assembly, and particularly relates to a positioning tool for installing a transmission top cover. Background Art

[0002] Currently, with the rapid development of the automotive industry and the diversification of market demands, automotive transmissions are also developing towards multi-polarization. In order to quickly complete the assembly of transmission top covers with different structural requirements, replacing the assembly tool that saves time and effort is an effective way to improve assembly efficiency.

[0003] Due to the large volume of the transmission top cover, when installing the positioning pin in the workshop currently, one person needs to hold the operating shaft to overcome the pressure of the spring on the operating shaft so that the operating shaft retracts and the pin hole on the operating shaft is exposed from the assembly window of the top cover housing before the positioning pin can be installed. Therefore, a single person cannot operate, and it requires the cooperation of two people. One person presses the shaft and the other installs the pin, which requires a lot of labor and has low assembly efficiency. Summary of the Invention

[0004] The technical problem to be solved by the present invention is that when installing the positioning pin in the transmission top cover in the workshop currently, it requires the cooperation of two people, which requires a lot of labor and has low assembly efficiency.

[0005] The present invention provides the following technical solution: A positioning tool for installing a transmission top cover, including a support table, on which a number of support points are distributed. The number of support points respectively correspond to the force application points on the transmission top cover. The number of support points are used to horizontally support the transmission top cover. Among them, some support points cooperate with the concave-convex structure on the transmission top cover to limit the axial movement of the transmission top cover along its operating shaft. A pushing component that advances towards the operating shaft is arranged in the front of the support table in the axial direction of the operating shaft. The pushing component cooperates with the guiding component on the support table. A elastic component is arranged between the pushing component and the reaction support on the support table. The elastic component makes the pushing component maintain the tendency to move towards the operating shaft. A limiting component is arranged in front of the moving path of the pushing component to limit the stroke of the pushing component.

[0006] Further, the support table includes a bottom plate, on which a first vertical plate and a second vertical plate are erected. A first cushion block and a push plate are sequentially arranged between the first vertical plate and the second vertical plate. A second cushion block is attached to the side of the first vertical plate facing away from the first cushion block. The first cushion block and the second cushion block are used to support the transmission top cover. The part of the first vertical plate that is higher than the second cushion block is used to be inserted into the structural gap of the transmission top cover. A linear guiding component is arranged between the push plate and the second vertical plate. The push plate is slidably matched with the linear guiding component.

[0007] Further, the linear guiding component includes two sliding rods, which are parallel to each other and horizontally connected between the first vertical plate and the second vertical plate. The distance between the two sliding rods allows the transmission top cover to pass through and rest on the first cushion block. The push plate is assembled on the sliding rods through the guide holes corresponding to the two sliding rods one by one, and a spring is sleeved on the sliding rod section between the push plate and the second vertical plate.

[0008] Further, a limiting block is arranged on the bottom plate. The spring pushes the push plate, and the bottom end of the push plate abuts against the limiting block.

[0009] Further, two holes are formed in the push plate, and a sleeve is installed in each hole. The hole of the sleeve is in guiding fit with the sliding rod.

[0010] Compared with the prior art, the advantages of the present invention are as follows:

[0011] A transmission top cover installation and positioning tool provided by the present invention adopts a push plate spring structure, which not only realizes single-person operation, but also improves the assembly efficiency. The assembly efficiency is increased from 10 per hour to 15 per hour, and at the same time, the labor intensity of the operator is reduced, ensuring the operation safety of the operator.

[0016] In order to more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the following will briefly introduce the drawings required for the description of the embodiments or the prior art. Obviously, the following drawings are only some embodiments of the present invention. For those of ordinary skill in the art, without creative efforts, other drawings can be obtained based on these drawings.

[0017] A transmission top cover installation positioning tool includes a support platform, on which several support points are distributed. The several support points respectively correspond to the force application points on the transmission top cover, and the several support points are used to horizontally support the transmission top cover. Among them, some support points cooperate with the concave-convex structure on the transmission top cover to limit the axial movement of the transmission top cover along its operation axis. A pushing component that advances towards the operation axis is arranged on the support platform directly in front of the operation axis in the axial direction. The pushing component cooperates with the guiding component on the support platform, and an elastic element is arranged between the pushing component and the reaction support on the support platform. The elastic element makes the pushing component maintain a tendency to move towards the operation axis. A limiting component is arranged in front of the moving path of the pushing component, and the limiting component limits the stroke of the pushing component.

[0018] As Figure 1 、 Figure 2 、 Figure 3 shown: The support platform includes a bottom plate 1, on which a first vertical plate 2 and a second vertical plate 3 are erected. A first cushion block 4 and a push plate 5 are sequentially arranged between the first vertical plate 2 and the second vertical plate 3. A second cushion block 6 is attached to the side of the first vertical plate 2 facing away from the first cushion block 4. The first cushion block 4 and the second cushion block 6 are used to support the transmission top cover. The part of the first vertical plate 2 that is higher than the second cushion block 6 is used to be inserted into the structural gap of the transmission top cover. A linear guiding component is arranged between the push plate 5 and the second vertical plate 3, and the push plate 5 is slidably matched with the linear guiding component.

[0019] The linear guiding component includes two sliding rods 7, which are parallel to each other and horizontally connected between the first vertical plate 2 and the second vertical plate 3. The distance between the two sliding rods 7 allows the transmission top cover to pass through and be placed on the first cushion block 4. The push plate 5 is assembled on the sliding rods 7 through the guide holes corresponding to the two sliding rods 7 one by one, and a spring 8 is sleeved on the sliding rod section between the push plate 5 and the second vertical plate 3. The push plate spring structure can effectively avoid scratching the operation shaft 12 and is also applicable to transmission top covers with different lengths, with strong versatility.

[0020] A limiting block 9 is arranged on the bottom plate 1. The spring 8 pushes the push plate 5, and the bottom end of the push plate 5 abuts against the limiting block 9. The limiting block 9 effectively limits the stroke of the push plate 5, which is limited to the loading and unloading of the transmission top cover.

[0021] Two holes are opened on the push plate 5, and a sleeve 10 is installed in each hole. The hole of the sleeve 10 is in guiding cooperation with the sliding rod 7. The sleeve structure is adopted at the hole of the push plate 5, which can reduce friction and increase the service life. Since the push plate 5 is relatively thin, the addition of the sleeve 10 extends the cooperation length between the push plate 5 and the sliding rod 7, and can improve the stability of the push plate 5 during sliding.

[0022] As Figure 2 、 Figure 3As shown: When installing the positioning pin inside the transmission top cover, push the push plate 5 to the left, then clamp the transmission top cover onto the installation positioning tool. The push plate 5 is reset by the thrust of the spring 8 and pushes the operating shaft to retract into the transmission top cover for the installation of the positioning pin.

[0023] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
