Description
Technical Field
The utility model belongs to the mechanical assembly field relates to a pressure equipment device, especially relates to a pressure equipment device for two skeleton oil seals.
Background
In the prior art, the conventional way of installing a framework oil seal in an inner hole of a bearing seat is as follows: the inner lip of the oil seal is sealed with the shaft, and the excircle of the oil seal is sealed with the inner hole of the bearing seat in a matching way. Generally, the framework oil seal is mostly installed by adopting a manual direct knocking-in mode, so that the labor intensity of workers is high, and the framework oil seal is easy to deform due to uneven stress caused by the manual knocking-in installation mode, so that oil leakage occurs during subsequent debugging; in addition, the method of installing the framework oil seal by manually knocking in cannot ensure the installation precision, the installation precision is poor, and the deformation probability of the framework oil seal is increased by repeated knocking correction; in the past, a framework pressing oil seal device is adopted, which can greatly reduce the labor intensity of workers and improve the production efficiency, but only one framework oil seal can be pressed at a time.
The invention patent application "oil injection type double oil seal device" published by the national intellectual property office 2018.10.09 is filed as follows: 2018.03.28, patent application No.: 201810263889.0, publication number: CN108626358A, which is close to the content of this application. The oil injection type double oil seal device comprises an end cover, a pressing plate, an oil injection pressing cup and an oil seal, wherein the end cover is connected on a shaft which is supported between an upper box body and a lower box body through a bearing in a penetrating mode and is locked through pressing of the pressing plate in a pressing mode, the end cover is locked on the upper box body and the lower box body, the inner wall of the end cover is provided with the oil seal which is arranged by two axial sealing connecting shafts, the upper portion of the end cover is provided with an oil pressing channel, the outer opening of the oil pressing channel is connected with the. This application has prevented the oil blanket wearing and tearing, has improved the sealing performance of oil blanket, but only is limited to the structure of oil blanket itself, still relies on manual operation to oil blanket's installation.
Therefore, a press-fitting device for a double-framework oil seal is needed to be designed, which can meet the processing requirements, and simultaneously can enable an operator to operate conveniently and use efficiently.
SUMMERY OF THE UTILITY MODEL
To the above problem, the utility model provides a pressure equipment device for two skeleton oil seals to solve that the workman intensity of labour who has the mode pressure equipment skeleton oil seal of the manual dress of adopting now exists is big, production efficiency is low, the installation accuracy subalternation problem.
In order to realize the above purpose, the utility model adopts the technical scheme that: a press-fitting device for a double-framework oil seal comprises a base, an inner hexagonal cylindrical head screw, a spring washer, a spring, a positioning shaft, a sliding sleeve, a framework oil seal and a separation bearing seat; after the positioning shaft is sleeved with the spring and the sliding sleeve, the positioning shaft is installed on the base through the inner hexagonal socket head cap screw and the spring washer, the two framework oil seals are sequentially installed on the positioning shaft, and then the separating bearing seat is placed on the sliding sleeve.
The sliding sleeve is a cylinder with the middle part being through and different stepped diameters, the positioning shaft penetrates through the middle part of the sliding sleeve, and the spring can axially stretch and move around the positioning shaft in the cylinder at the lower part of the sliding sleeve.
The size of the aperture at the bottom end of the separation bearing seat is in movable fit with the diameter of the framework oil seal.
The utility model adopts the above technical scheme have following positive effect: the device can press-fit two framework oil seals at a time, has compact structure, simplicity, practicability, simple and convenient operation and light movement, can lighten the labor intensity of an operator, and can improve the working efficiency.
Drawings
Fig. 1 is a schematic sectional structure diagram of the press-fitting device for a double-skeleton oil seal of the present invention.
Wherein: the bearing seat comprises a base 1, a base 2, an inner hexagonal socket head cap screw 3, a spring washer 4, a spring 5, a positioning shaft 6, a sliding sleeve 7, a framework oil seal 8 and a separation bearing seat.
Detailed Description
The present invention will be further described with reference to the accompanying drawings and examples. As shown in figure 1, after a spring 4 and a sliding sleeve 6 are sleeved on a positioning shaft 5, a framework oil seal 7 is sequentially placed on the positioning shaft 5 through an inner hexagonal socket head cap screw 2 and a spring washer 3 and then a separation bearing seat 8 is placed on the sliding sleeve 6. The sliding sleeve 6 is a cylinder with a through middle and stepped different diameters, the positioning shaft 5 penetrates through the middle of the sliding sleeve 6, and the spring 4 can axially stretch and move around the positioning shaft 5 in the cylinder at the lower part of the sliding sleeve 6. The aperture size of the bottom end of the separation bearing seat 8 is in movable fit with the diameter size of the framework oil seal 7.
The working principle is as follows: firstly, sequentially placing two framework oil seals 7 on the upper part of a positioning shaft 5; then the separation bearing seat 8 is placed on the sliding sleeve 6; downward pressing the press head of the press to a proper position; and (3) moving a press head upwards, pushing the sliding sleeve 6 upwards to a limit position through the spring 4, taking down the workpiece separation bearing seat 8 pressed into the two framework oil seals 7, and finishing the whole working process.
The utility model provides a mode pressure equipment skeleton oil blanket of traditional artifical dress of beating, it is big, production efficiency is low, the installation accuracy is poor to have solved workman intensity of labour to the skeleton oil blanket easily receives the damage deformation and leads to the oil leak scheduling problem. The device can press-fit two framework oil seals at a time, and has the advantages of compact structure, simplicity, practicability, simplicity and convenience in operation and movement.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art will understand that various changes, modifications and substitutions can be made without departing from the spirit and scope of the present invention. All changes, modifications, equivalents and the like which come within the spirit of the invention are intended to be embraced therein.
