Description

Technical Field

[0001] The present application relates to the technical field of oil seal devices, and in particular to a pressurized oil seal tooling. Background Art

[0002] Right angle motors, also known as right angle gearboxes or right angle transmissions, are a special type of motor whose notable feature is that the rotor shaft is at right angles to the stator shaft, thereby achieving a right angle turn for power transmission. Right angle motors include a cover and a housing, both of which require oil seals to be installed to ensure that the lubricating oil inside the housing does not leak and external contaminants do not enter. Before installing the oil seal, ensure that the surface of the sealing part on the right angle housing is smooth and has no obvious wear or damage. At the same time, before installation, apply a layer of lubricant on the lip of the oil seal to reduce friction during installation and prevent damage to the oil seal; then use a rubber hammer or other tools to slowly and evenly push the oil seal into the oil seal seat.

[0003] During the installation of the oil seal, some tools are used to install the oil seal, and the oil seal may have problems such as deflection, eccentricity, and even scratches on the housing or the surface of the oil seal, all of which will affect the quality of the oil seal. Summary of the invention

[0004] In order to facilitate the installation of the oil seal, the present application provides an oil seal pressing tool.

[0005] This application provides the following technical solutions:

[0006] A pressure oil seal tooling comprises a workbench, an extrusion member slidably arranged on the workbench up and down, a material receiving part vertically arranged on the workbench, and a support member arranged on the workbench and located below the extrusion member, wherein the support member comprises a support plate and an elastic member connected between the support plate and the workbench; the upper end of the material receiving part passes through the support plate and has a portion exceeding the surface of the support plate, and the support plate can be pressed by the extrusion member to move downward and the elastic member is compressed.

[0007] By adopting the above technical solution, the upper end of the material receiving part is used to place the oil seal, the box is placed on the support plate, and the material receiving part can extend into the inner cavity of the box. When the extrusion part moves downward and abuts against the box, it can simultaneously push the support plate to move downward, while the material receiving part remains stationary. Therefore, during the downward movement of the box, the oil seal at the upper end of the material receiving part can be squeezed into the corresponding position of the inner cavity of the box; when the extrusion part is reset, the support plate also moves upward and resets under the action of the elastic part, so that the oil seal can be installed in the box and the box can be removed. By adopting the above tooling, the efficiency of oil seal installation is improved and the installation is more accurate, and the situation of artificial scratching of the box and the oil seal can be reduced.

[0008] Optionally, the material receiving portion includes a column and a material receiving platform arranged at the upper end of the column, and a protrusion extending upward is coaxially arranged on the upper end surface of the material receiving platform, and a first step edge for placing an oil seal is formed between the protrusion and the material receiving platform.

[0009] By adopting the above technical solution, the oil seal sleeve is arranged on the outer wall of the protrusion. When the box moves downward, the first step can move relatively close to the position where the oil seal is installed in the box, and the oil seal is installed at the corresponding position of the box.

[0010] Optionally, a second step edge is further provided on the periphery of the first step edge on the upper edge of the material receiving platform, and when the support plate is pressed by the extrusion member and moves downward, the second step edge can abut against the inner wall of the box body.

[0011] By adopting the above technical solution, a second step edge is also provided on the material receiving table. When the oil seal is pushed into the installation position of the box body through the first step edge, the second step edge can abut against the inner wall of the box body, so that the first step edge will no longer squeeze the oil seal, thereby reducing deformation of the oil seal caused by excessive squeezing.

[0012] Optionally, a positioning platform is provided on the support plate, a clearance hole is opened on the positioning platform, the material receiving part passes through the clearance hole, and the box body can be snap-connected to the positioning platform.

[0013] By adopting the above technical solution, the lower end of the positioning platform can be clamped in the hole at the lower end of the box, so that the positioning platform can pre-position the box, and the box is not prone to displacement during the extrusion process of the extrusion plate.

[0014] Optionally, the support plate is provided with a sliding rod extending downward and slidingly passing through the workbench, and the elastic member is provided on the outer wall of the sliding rod.

[0015] By adopting the above technical solution, the sliding rod slides through the workbench. When the support plate moves downward, the elastic member is compressed and the sliding rod slides downward. Under the action of the sliding rod, the support plate slides more stably.

[0016] Optionally, a frame is provided on the workbench, and the extrusion member includes an extrusion plate and a driving source installed on the frame and used for driving the extrusion plate to move up and down, and the extrusion plate is located above the support plate.

[0018] Optionally, a guide rod is provided on the extrusion plate, and the guide rod slides through the frame.

[0019] By adopting the above technical solution, under the action of the guide rod, the extrusion plate can move up and down more stably, thereby improving the stability when installing the press-fit oil seal.

[0020] Optionally, a plurality of the material receiving parts are provided, and the positioning platforms correspond to the material receiving parts one by one.

[0021] By adopting the above technical solution, a plurality of material receiving parts are provided, so that a plurality of boxes can be installed simultaneously each time, thereby improving work efficiency.

[0022] Optionally, it also includes a lifting plate capable of moving up and down in a vertical direction and a power source for driving the lifting plate to move up and down. The upper surface of the workbench is provided with a material placement table for placing the cover body, and the lifting plate is provided with a material seat for positioning the oil seal. The power source moves downward so that the material seat is inserted into the cover body.

[0023] By adopting the above technical solution, the cover body is placed on the material discharge table, the oil seal sleeve is arranged on the material seat, and when the material seat moves downward and extends into the cover body, the oil seal is installed in the cover body.

[0024] In summary, the present application includes at least one of the following beneficial effects:

[0025] 1. When installing the oil seal in the box, place the oil seal on the material receiving platform, place the box on the support plate, and then move the extrusion plate downward to push the support plate downward, so that the material receiving platform pushes the oil seal into the installation position of the oil seal in the box. After the extrusion plate is reset, the elastic member pushes the support plate to reset, so that the box and the material receiving platform are out of contact. BRIEF DESCRIPTION OF THE DRAWINGS
