Abstract
The utility model relates to a machine maintenance device, particularly to a piston cylinder straightening device. The device comprises a frame constituted by a working table and supporting legs mounted at two ends of the working table, and a fluid cylinder mounted at one end of the frame. The device is characterized in that door-shaped frameworks are fixedly mounted at two ends of the working table in the frame respectively, wherein the fluid cylinder is mounted on the door-shaped framework at one end, and support plates are arranged at the positions corresponding to the support plate and the door-shaped framework at the other end and on a piston cylinder required to be straightened and arranged at the middle of the working table respectively; and semicircular arcs are formed on the three support plates respectively and are matched with the piston cylinder to be straightened in diameter. According to the utility model, the three supporting points are all in surface contact during the straightening process, so that the defect that the piston cylinder deforms in the circumferential direction during the straightening process can be avoided effectively; and meanwhile, the device is provided with a detection device which can detect the straightening condition of the piston cylinder conveniently. The device has the characteristics of simple structure, convenience in operation and detection, and the like.
Description
Technical field
The utility model relates to a kind of machine maintenance device, particularly a kind of piston cylinder coalignment.
Background technology
Hydraulic cylinder or cylinder are made up of cylinder body and the piston that is sleeved in the cylinder body, can only bear axial force.Present large-scale self-tipping type engineering truck is to adopt hydraulic cylinder that wagon box jack-up is accomplished self-unloading work.Because problems such as natural environment and climates, in discharge process, the compartment might receive the active force of side force, thereby causes cylinder body or piston bending.And the piston in the hydraulic cylinder that uses on the self-tipping type engineering truck generally is to be processed by seamless steel pipe, carries out causing the distortion of circumferencial direction easily in the alignment repair process, and this is one of difficult point of large-scale self-tipping type engineering truck hydraulic cylinder reparation.And more the expense of transducer set hydraulic cylinder increases the vehicle cost of use generally at one, 20,000 yuan.
Summary of the invention
The purpose of the utility model provides a kind of in the process of alignment piston cylinder, can guarantee that the circumferencial direction of piston cylinder is indeformable basically, promptly in alignment process, guarantees the constant basically piston cylinder coalignment of circularity of piston cylinder part in compression.
For realizing above-mentioned purpose; Technical scheme of the present invention is: a kind of piston cylinder coalignment; Comprise by workbench be installed in the frame that the supporting leg at two ends is formed below the workbench and be installed in the hydraulic cylinder of frame one end, the shape framework that it is characterized in that two ends are installed with respectively on workbench " door " wherein is equipped with hydraulic cylinder on the crossbeam of " door " shape framework of an end; With the piston cylinder that needs alignment at the middle part of the crossbeam opposite position of hydraulic cylinder, the other end " door " shape framework and workbench on; Be placed with gripper shoe respectively, all have semi arch on above-mentioned three gripper shoes, the diameter of this semi arch with matched by alignment piston cylinder diameter.
The measurement mechanism of measuring the piston cylinder linearity is installed in the side of above-mentioned workbench.
Above-mentioned measurement mechanism is by being installed in two the relative bracing frames in workbench side and being installed on the bracing frame two rollers of horizontal symmetrical and forming.
Above-mentioned hydraulic cylinder is a jack.
The utility model mainly is in 3 alignment process; With the contact of existing some contact becoming face; So just make three strong points in the alignment process be the face contact; Avoided causing in the alignment process distortion of piston cylinder circumferencial direction effectively, this device also is equipped with checkout gear simultaneously, can conveniently detect the alignment situation of piston cylinder.That this device has is simple in structure, operation, characteristics such as easy to detect.
Description of drawings
Accompanying drawing 1 is the utility model structural representation;
Accompanying drawing 2 is the left view of the utility model accompanying drawing 1.
The specific embodiment
Like Fig. 1, shown in 2, workbench 7 is supported on ground through the supporting leg at two ends, and two ends are installed with " door " shape framework respectively on workbench, wherein on the crossbeam of " door " shape framework I 3 of left end hydraulic cylinder 1 is installed, and hydraulic cylinder can adopt jack.The measurement mechanism 5 of measuring the piston cylinder linearity is installed in the side of workbench, measurement mechanism by two bracing frame 5-1 that are installed in the workbench side be installed in that two roller 5-2 of horizontal symmetrical form on the bracing frame.
During use, at first will need the piston cylinder 4 of alignment to be placed on the measurement mechanism and be rotated, the piston cylinder surface measured, and find out the laggard rower of crooked position and annotate through dial gauge.On workbench, place then with the piston cylinder that needs alignment matches and have a semi arch gripper shoe II 6; The position that piston cylinder is crooked is placed in the semi arch of gripper shoe II; Under the crossbeam of right side " door " shape framework II 10; The gripper shoe III 9 of band semi arch is buckled on the piston cylinder,, adjusts the piston cylinder maintenance basic horizontal between gripper shoe II, the gripper shoe III through between the crossbeam of the end face of gripper shoe III and right side " door " shape framework, placing cushion block 8; Piston corresponding position on piston cylinder left end and jack is buckled in the gripper shoe I 2 of being with semi arch on the piston cylinder then.Because the intermediate support plate II is supported on the piston cylinder crooked position, when the crooked position right side was adjusted into level, the crooked position left side was upturned; To pressing down the gripper shoe I, pressure passes to piston cylinder through the semicircle cambered surface that matches with the piston cylinder diameter on the gripper shoe I through jack, in, right 2 supports; Under the effect of left end downforce; Through repeatedly pressure straightening, detection repeatedly, just can be with the piston cylinder alignment of bending, and the variation of piston cylinder circularity is very little.
Claims (4)
1. piston cylinder coalignment; Comprise by workbench be installed in the frame that the supporting leg at two ends is formed below the workbench and be installed in the hydraulic cylinder of frame one end; It is characterized in that two ends are installed with " door " shape framework respectively on workbench (7); Wherein on the crossbeam of " door " shape framework of an end hydraulic cylinder (1) is installed, with the piston cylinder that needs alignment at the middle part of the crossbeam opposite position of hydraulic cylinder, the other end " door " shape framework and workbench on, be placed with gripper shoe respectively; All have semi arch on above-mentioned three gripper shoes, the diameter of this semi arch with matched by alignment piston cylinder diameter.
