In the pneumatic cylinder working process, because the frequent reciprocating motion of pneumatic cylinder, especially, engineering machine tool pneumatic cylinder operating mode is more abominable, operating pressure is also bigger, and when the pneumatic cylinder reaches the maximum stroke, can produce a great impact force to the uide bushing, some pneumatic cylinders still can receive the lateral force from the external world, inside impact and outside lateral load all can the direct influence performance of uide bushing, produce the damage of different degrees to the screw thread of uide bushing, so may lead to the screw thread to become invalid for a long time, the uide bushing is not hard up, the performance of direct influence pneumatic cylinder product.
Referring to fig. 1 and 2, in the prior art, a shallow groove is machined at a position, close to the outer circle of a guide sleeve, of the outer circle of a cylinder barrel, and after the guide sleeve is installed, the guide sleeve is bent by external force to prevent looseness;
the anti-loose technology has the following problems:
1. the anti-loosening effect is uncontrollable, the reliability is low, and the anti-loosening effect is not ideal;
2. the risk of thread damage is generated in the process of bending by external force;
3. the bending and looseness prevention are irreversible, the guide sleeve is difficult to disassemble in the later maintenance process and easily damages threads, the disassembled guide sleeve can not be used continuously due to the damage of the threads after the repair is completed, and the maintenance cost is increased.
Disclosure of Invention
In order to solve the technical problem, the utility model provides a pneumatic cylinder uide bushing locking device of bent plate area round pin axle.
The utility model discloses a following technical scheme realizes: a hydraulic cylinder guide sleeve anti-loosening device with a bent plate and a pin shaft comprises a cylinder barrel and a guide sleeve arranged at the end part of the cylinder barrel; the cylinder barrel is characterized by also comprising a bent plate, wherein one end of the bent plate is provided with a pin hole, and the other end of the bent plate is connected with the end part of the cylinder barrel; the end part of the guide sleeve is provided with a positioning hole; and a pin shaft is arranged between the bent plate pin hole and the guide sleeve positioning hole.
It further comprises the following steps: the pin shaft is in interference fit with the bent plate pin hole, the pin shaft is pressed into the bent plate pin hole from the outer side, and the inner end of the pin shaft extends out of the pin hole.
The bent plate is bent by 90 degrees, and one end of the bent plate is attached to the outer circumferential surface of the cylinder barrel and fixed with the outer circumferential surface of the cylinder barrel through spot welding; the other end of the bent plate is attached to the end face of the guide sleeve.
Compared with the prior art, the beneficial effects of the utility model are that:
1. the structure is simple, the anti-loosening effect is good, the oil leakage phenomenon caused by the looseness of the guide sleeve is effectively avoided, and the occurrence of faults is reduced;
2. the threaded connection between the guide sleeve and the cylinder barrel is not damaged; when the hydraulic cylinder is maintained in the later stage, only the welding seam between the bent plate and the cylinder barrel needs to be polished and removed, so that the hydraulic cylinder is convenient to maintain and disassemble and convenient to reassemble, the maintenance cost of the hydraulic cylinder is reduced, and the service life of the hydraulic cylinder is prolonged.
