Description

Technical Field

[0001] The utility model relates to the field of oil seal processing tooling, in particular to an oil seal multi-part pre-oiling tooling. Background Art

[0002] The oil seal product is one of the important sealing components to prevent lubricating oil leakage. The original oil seal products need to be manually oiled before shipment or assembly. Due to the special structure of the oil seal products, they usually include a skeleton structure and a rubber body. The rubber body usually has multiple structures such as multiple inner sealing lips and multiple outer sealing lips. The existence of the sealing lips causes spatial stratification of the oil seal in the ordinary pre-oiling tooling. During the pre-oiling process, multiple toolings are required for oiling and pre-lubrication, which leads to an increase in the operation time and a significant decrease in work efficiency. Moreover, due to multiple tooling conversions, there is a risk of oil seal damage.

[0003] To save operation time, improve work efficiency, and simplify the process, it is necessary to develop a tooling according to the shape and size of the oil seal product that can complete the pre-oiling of all parts of the entire oil seal with a single oiling. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an oil seal pre-oiling tooling that can pre-oil multiple parts of the oil seal, aiming to solve the problem that the existing oiling tooling needs to be replaced multiple times to complete the pre-oiling of the oil seal.

[0005] The technical solution adopted by the utility model is: an oil seal multi-part pre-oiling tooling, including a base. There is a thread on the left side wall of the base, a limit rib is provided on the upper left part of the base, an outer support block is provided on the left side of the base, and the outer support block is connected to the base by a thread. The cross-section of the outer support block is in an "L" shape. There is an installation position at the upper end of the outer support block, and a positioning block is installed on the installation position through a screw. A limit block is provided above the base. There is a "U"-shaped groove on the left part of the limit block, and a support foot is provided at the lower right of the "U"-shaped groove. The support foot abuts against the limit rib so that a spaced space is formed between the left part of the positioning block and the outer support block. Multiple oil injection holes are provided on the "U"-shaped groove, and a sunken support surface is provided at the upper end of the left part of the "U".

[0006] A further technical solution of the utility model is: a horizontal oil injection hole is provided on the left part of the "U"-shaped groove, a horizontal oil injection hole is provided on the right side, and a vertical oil injection hole is provided at the bottom. By providing oil injection holes in multiple directions, the oil seal can be oiled at multiple parts during pre-oiling.

[0007] A further technical solution of the utility model is: a pipeline laying space is left between the lower part of the limit block and the base, which is convenient for laying the oil injection pipeline.

[0008] A further technical solution of the present utility model is that a thread is provided on the right side of the base, facilitating docking with an automatic oil injection device.

[0009] A further technical solution of the present utility model is that a thread is provided on the right side of the positioning block, facilitating docking with an automatic oil injection device.

[0010] The beneficial effect of the present utility model is that due to the above technical solution, a multi-part pre-lubricating tooling for oil seals of the present utility model is simple and fast to operate, can quickly pre-lubricate multiple parts of the oil seal product, simplifies the production process, and effectively improves production efficiency.

[0012] The present utility model will be further described below in conjunction with the drawings and specific embodiments.

[0013] Embodiment:

[0014] As Figure 1 shown, a multi-part pre-lubricating tooling for oil seals includes a base 1. A thread is provided on the left side wall of the base. A limiting rib 11 is provided on the upper left part of the base. An outer support block 2 is provided on the left side of the base. The outer support block 2 is connected to the base 1 by a thread. The cross-section of the outer support block is in an "L" shape. An installation position 21 is provided at the upper end of the outer support block. A positioning block 3 is installed on the installation position through a screw 31. The positioning block 3 can effectively prevent the oil seal from jumping during pre-lubrication. A limiting block 4 is provided above the base 1. A "U" - shaped groove 41 is provided on the left part of the limiting block. A support foot 5 is provided right below the "U" - shaped groove. The support foot 5 abuts against the limiting rib to form a spaced space between the left part of the positioning block and the outer support block, and can prevent the limiting block from shifting during operation. A plurality of oil injection holes 6 are provided on the "U" - shaped groove. A sunken support surface is provided at the upper end of the left part of the "U".

[0015] Furthermore, a horizontal oil injection hole is provided on the left part of the "U" - shaped groove, a horizontal oil injection hole is provided on the right side, and a vertical oil injection hole is provided at the bottom. By providing oil injection holes in multiple directions, oil can be applied to multiple parts of the oil seal during pre-lubrication.

[0016] Furthermore, a pipeline laying space 7 is left between the lower part of the limiting block and the base, facilitating the laying of the oil injection pipeline.

[0017] Furthermore, a thread is provided on the right side of the base, facilitating docking with an automatic oil injection device.

[0018] Furthermore, a thread is provided on the right side of the positioning block to facilitate docking with automatic oil filling equipment.

[0019] When using the tooling, place the oil seal 8 on the tooling, the lower half of the oil seal will be in the "U"-shaped groove, the sealing lips (inner sealing lips and outer sealing lips) of the oil seal, and the upper half of the oil seal will be exposed. The positioning block is locked by a screw, and the positioning block will rest against the upper side wall of the oil seal. Then, oil is injected into the tooling through the automatic oil injection equipment, and the oil enters through the oil injection hole to infiltrate multiple parts of the oil seal, completing the pre-oiling process.

[0020] In addition, the positioning block described in the present solution can be designed according to the structural dimensions of the oil seal, and the positioning block can be replaced according to the oil seals of different structures during use, thereby improving the flexibility of the tooling use.
