Description
Technical Field
The utility model relates to the technical field of oil seal production tools, in particular to a PTFE oil seal assembly tool.
Background
With the continuous development of the automobile industry, the PTFE oil seal also provides higher requirements for automobile parts, and the unique properties of the PTFE oil seal, such as ultrahigh speed resistance, high and low temperature resistance and various corrosive working media, occupy a position in the oil seal market, but due to the production process characteristics, the PTFE lip with sealing function needs to be manually and directly pressed and shaped by a special two-stage shaping tool after the oil seal is vulcanized and shaped at one time, so that the PTFE oil seal is directly pressed and shaped without positioning in the assembly process, concentricity is difficult to ensure, the failure rate of the PTFE oil seal is increased, and the assembly failure is easy to be caused for a customer who adopts a mode of pressing the oil seal on the shaft firstly and then pressing the shaft together with the oil seal into the shell.
Disclosure of utility model
In order to solve the problems in the prior art, the utility model provides the PTFE oil seal assembly tool, which can ensure the concentricity of an oil seal in the lip shaping process and reduce the risk of failure of the PTFE oil seal due to poor concentricity.
In order to achieve the above purpose, the present utility model provides the following technical solutions: the utility model provides a PTFE oil blanket equipment frock, includes supporting seat and location core, the supporting seat includes disc bottom plate and fixed connection at the spacing drum on disc bottom plate upper portion, the location core has been placed on the disc bottom plate, the location core includes drum main part and fixed connection be in the location ring of drum main part surface bottom, the external diameter of location ring with the internal diameter of spacing drum is coaxial.
By adopting the structural design, the PTFE oil seal has better concentricity by fixing the outer diameter of the PTFE oil seal and shaping the lip piece.
Preferably, the top of the cylinder main body is fixedly connected with a handle.
By adopting the structural design, after the adjustment of the PTFE oil seal lip piece is completed, a worker conveniently puts the positioning core out, and the PTFE oil seal is prevented from being directly taken out to cause upper damage to the PTFE oil seal.
Preferably, a circle of annular groove is formed between the limiting cylinder and the cylinder main body, the annular groove is used for placing the PTFE oil seal, the inner diameter of the limiting cylinder is the same as the outer diameter of the PTFE oil seal, and the outer diameter of the cylinder main body is the same as the inner diameter of the PTFE oil seal.
By adopting the structural design, the annular groove formed between the limiting cylinder and the cylinder main body can limit the position of the PTFE oil seal and prevent the PTFE oil seal from shifting.
Preferably, the sides of the limiting cylinder and the cylinder body, which are close to the annular groove, are inclined planes.
By adopting the structural design, the width of the top of the annular groove is increased, and an operator can place the PTFE oil seal into the groove more conveniently.
Compared with the prior art, the utility model has the advantages and positive effects that: the PTFE oil seal has good concentricity by fixing the outer diameter of the PTFE oil seal and shaping the lip piece; the shaping core can enter the oven together with the PTFE oil seal to carry out secondary vulcanization, an independent secondary shaping tool is not needed, a plurality of oil seals can be serially connected and shaped at one time under the condition that the PTFE oil seal is ensured to be not adhered through secondary vulcanization (such as an external leakage framework), and the production efficiency can be improved.

Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
The utility model provides a PTFE oil blanket equipment frock, includes supporting seat 1 and location core 2, supporting seat 1 includes disc bottom plate 12 and fixed connection at the spacing drum 11 on disc bottom plate 12 upper portion, the location core 2 has been placed on the disc bottom plate 12, location core 2 includes drum main part 21 and fixed connection be in the location ring 22 of drum main part 21 surface bottom, the external diameter of location ring 22 with the internal diameter of spacing drum 11 is coaxial. Since the outer diameter of the positioning ring 22 is the same as the inner diameter of the limiting cylinder 11, the positioning core 2 is fixed after being placed on the supporting seat 1. Through the fixing of the outer diameter of the PTFE oil seal 4, the shaping of the lip piece is carried out, so that the PTFE oil seal 4 has good concentricity.
A circle of annular groove is formed between the limiting cylinder 11 and the cylinder main body 21, the annular groove is used for placing the PTFE oil seal 4, the inner diameter of the limiting cylinder 11 is the same as the outer diameter of the PTFE oil seal 4, and the outer diameter of the cylinder main body 21 is the same as the inner diameter of the PTFE oil seal 4.
The top of the cylinder main body 21 is fixedly connected with a handle 3. After the adjustment of the PTFE oil seal 4 lip piece is completed, a worker conveniently puts the positioning core 2 out, and the PTFE oil seal 4 is prevented from being directly taken out to cause upper damage to the PTFE oil seal 4.
A circle of annular groove is formed between the limiting cylinder 11 and the cylinder main body 21, the annular groove is used for placing the PTFE oil seal 4, the inner diameter of the limiting cylinder 11 is the same as the outer diameter of the PTFE oil seal 4, and the outer diameter of the cylinder main body 21 is the same as the inner diameter of the PTFE oil seal 4.
