The stretching device generally comprises a guide screw, a bedplate, a base plate and a supporting seat, wherein the guide screw is fixed on the bedplate, the base plate moves up and down along the guide screw through a guide sleeve, the supporting seat is arranged below the base plate, and the base plate has air tightness requirements due to pneumatic equipment of the device, so that a sealing ring is required to be installed on the base plate, and a buffer device is required to be installed between the base plate and the supporting seat due to larger impact force of the device on the base plate. The sealing ring and the buffer device in the prior equipment are independently installed. In the actual production process, the sealing ring is easy to damage due to frequent up-and-down movement of the base plate, the buffer device is also likely to malfunction, and the two parts are difficult to maintain.
Therefore, how to improve the existing stretching device to overcome the above problems is a problem to be solved by those skilled in the art.
Disclosure of Invention
The invention mainly aims to provide the bag-type stretching device with the sealing and buffering functions, which has the advantages of simple structure, good sealing performance, reliable buffering and convenient maintenance.
In order to achieve the above purpose, the invention adopts the following technical scheme: the bag-type stretching device with the sealing and buffering functions comprises a bedplate, guide screws, a base plate and a supporting seat, wherein the guide screws are fixed on the bedplate, the base plate is arranged on the guide screws in a sliding mode through guide sleeves, and the supporting seat is arranged below the base plate; the method is characterized in that: be provided with outer lane baffle and inner circle baffle on the supporting seat, outer lane baffle with the inner circle baffle sets up with one heart, outer lane baffle with be provided with tire-shaped gasbag between the inner circle baffle, the inside spherical gasbag that is provided with of inner circle baffle, tire-shaped gasbag with the spherical gasbag upper and lower both sides closely laminate the backing plate with the supporting seat, tire-shaped gasbag with spherical gasbag thickness is the same, and all is greater than outer lane baffle with the height of inner circle baffle.
As an improved implementation mode, the tire-shaped air bags and the spherical air bags are provided with air leakage holes, and elastic balls are filled in the tire-shaped air bags and the spherical air bags.
Preferably, the air leakage hole is formed in a side surface of the tire-shaped air bag and a side surface of the spherical air bag. The reason that the upper side and the lower side of the air bag are not provided with the air leakage holes is that the air bag is prevented from being tightly attached to the backing plate and the supporting seat, and the air tightness of the device is further prevented from being influenced.
As an improvement, the tire-shaped air bag and the spherical air bag are provided with replacement ports, the replacement ports can be opened and closed, and the elastic balls are allowed to enter and exit when the replacement ports are opened. Is used for conveniently replacing the elastic ball.
Further improved, the outer ring baffle is provided with an outer maintenance door, the inner ring baffle is provided with an inner maintenance door, and the outer maintenance door and the inner maintenance door can be opened and closed and are fixed through a lock catch when closed; the replacement port of the tire-shaped bladder is aligned with the outer service door and the replacement port of the spherical bladder is aligned with the inner service door. With the above arrangement, the elastic ball can be replaced without taking out the air bag.
Compared with the prior art, the invention has the following advantages: the arrangement of the tire-shaped air bag and the spherical air bag replaces a sealing ring and a buffer device, combines the functions of the tire-shaped air bag and the spherical air bag together, has the sealing effect and the buffer effect, and ensures that the device has a simple and reliable structure; and the arrangement of two air bags ensures that the device has better sealing performance and buffering effect.
In addition, the improvement setting of gas leakage hole and elastic ball still has following advantage: when the equipment is used for a plurality of times or fails, the tire-shaped air bag and the spherical air bag are air-tight, so that the air bag is not damaged, and only the elastic ball inside the air bag is damaged; taking a tire-shaped air bag as an example, if the tire-shaped air bag is damaged for the first time or less times, the outer maintenance door can be directly opened, then the replacement port of the tire-shaped air bag is opened, and the elastic ball is directly added into the tire-shaped air bag; if the tire is maintained for many times, a plurality of broken elastic balls remain in the tire, the whole tire-shaped air bag is taken out, the broken elastic balls are removed, the pressure balls are reloaded, and the tire-shaped air bag is replaced for normal use. The improvement can ensure that the tire-shaped air bags and the spherical air bags are always in a normal working state, ensure the air tightness and the buffering function of the device, and the structure has long service life and is convenient to maintain.
