Abstract
The utility model relates to an I-shaped wheel pneumatic tightening device, which comprises a top shaft, a top disc and a cylinder. An inner sleeve is arranged at the inner side of the outer sleeve of the cylinder. The inner end of the inner sleeve is in a sealing connection with the outer sleeve through a piston head. The outer end of the inner sleeve is in a sealing connection with the port of the outer sleeve through a sealing ring. The top shaft is sleeved inside the core space of the inner sleeve. The inner and outer ends of the top shaft are respectively sleeved inside the inner sleeve through a roller bearing and a thrust bearing. The part of the outer end of the top shaft extending out of the inner sleeve is sleeved with the top disc. The top shaft and the top disc are cooperated with each other through a key arranged between the top shaft and the top disc. According to the utility model, the key cooperation structure between the top disc and the top shaft instead of a conventional bolt connection structure is adopted by the device, so that the problem that a bolt is easily broken when bearing an axial load and a radial load is solved. The top disc adopts an inner-outer ring combination structure, thus is easy in replacement and maintenance. Meanwhile, the service life of the top disc is prolonged and the production cost is lowered.
Description
Technical field:
The utility model relates to the pneumatic technology that holds out against of a kind of Loosen up wire wheel, is specifically related to the pneumatic holding device of a kind of I-beam wheel.
Background technology:
At present; The stopping of existing material retractable machine locking cylinder is mainly taked two kinds of forms: a kind of is the wedge lock block mode; In this mode, utilize screw-nut body or the stopping wedge is pushed up on the sliding sleeve of holding device through hydraulic gear (referring to utility model patent CN201613275U) by the operator; Utilize the inclined-plane on the wedge to increase friction force, guarantee that sliding sleeve can not prevent the industrial accident of I-beam wheel flywheel because of cylinder leakage tester falls back; Another kind is a twin shaft cylinder stopping mode; Wherein expansion link item of being responsible for I-beam wheel is tight for the twin shaft cylinder that promptly utilizes holding device; Another root expansion link of cylinder is stretched out by afterbody, and retaining plate is installed on it, when cylinder hold out against I-beam wheel put in place after; Stopping bolt and stopping thick stick that the operator will be installed on the casing put down; Make the stopping bolt be positioned at retaining plate hole afterwards, after the rotation of the stopping thick stick on the stopping bolt is put in place, utilize the self-locking of screw thread to guarantee that the cylinder expansion link can not fall back because of gas leakage.But in the unwrapping wire process, because of the dilating effect of wire rod extruding for I-beam wheel weakens gradually, after the I-beam wheel wing plates on two sides is attenuated to a certain degree, taking over a business of both sides can't be withstood I-beam wheel again, and the accident of I-beam wheel flywheel can take place in I-beam wheel unwrapping wire process.
Summary of the invention:
The utility model is to overcome deficiency and the defective that prior art exists, and provides a kind of I-beam wheel pneumatic holding device.
Technical scheme: the pneumatic holding device of a kind of I-beam wheel, comprise apical axis, take over a business, cylinder, outer sleeve one end of cylinder is provided with butt flange, and the other end is provided with the sealed outer end lid; The inboard of cylinder lagging tube is set with inner sleeve, and the inner of this inner sleeve is tightly connected through piston head and outer sleeve, and the outer end of this inner sleeve is connected with the outer sleeve port sealing through seal ring; Said inner sleeve contains inner chamber, and the inner of inner chamber is provided with the sealing internal end cover; Be set with apical axis in the inner chamber of inner sleeve vertically, the inside and outside end of this apical axis is set in the inner sleeve through coro bearng and thrust baring respectively; The part that inner sleeve is stretched out in the outer end of said apical axis is set with, and this apical axis with take over a business between key be set cooperate; The air inlet pipe of cylinder is communicated in first air chamber between outer end cap and the internal end cover, and freeing pipe is communicated in second air chamber between piston head and the outer sleeve.
Said take over a business to comprise taking over a business in ring and take over a business outer shroud, be provided with between ring and the apical ring outer shroud in the apical ring and mate the step surface that interlocks, two step surfaces through the bolt that is uniformly distributed with together.
The apical axis center is provided with axial oilhole, and the inner part of this axial oilhole is provided with radial hole, and the outer end of this axial oilhole is provided with oil filling port.
The outer end of apical axis also is fixed with cover plate, and the center of this cover plate is provided with central through hole.
The beneficial effect of the utility model: between cylinder lagging tube of the utility model and the inner sleeve piston head is set; Through bearing carrier ring apical axis is housed in the inner sleeve inner chamber; Taking over a business with apical axis adopts key to cooperate; Replace original bolt fastening structure, avoid bearing axially and the problem that is radially firmly fractureed easily because of bolt.Take over a business to be set to the inner and outer ring unitized construction, change easily and maintenance, strengthen and take over a business service life, reduce production costs.
