The following describes in further detail the embodiments of the present utility model with reference to the drawings and examples. The following examples are illustrative of the utility model and are not intended to limit the scope of the utility model.
Referring to fig. 1 to 2, the detachable press-fitting mechanism of the embodiment comprises a mounting rack 1, a screw rod sleeve 2 and a screw rod 3 in threaded fit with the screw rod sleeve are fixedly arranged on the mounting rack, a hand wheel 4 is arranged at the top end of the screw rod, a fixing sleeve 5 is arranged at the bottom end of the screw rod, the top end of the fixing sleeve is fixedly connected with the screw rod, a containing groove 6 is arranged at the bottom surface of the fixing sleeve, a limiting ring 7 positioned below the screw rod is arranged on the inner wall of the containing groove, a rotating block 8 is arranged in the fixing sleeve, the upper part of the rotating block is positioned in the containing groove and can move up and down along the containing groove, a mounting groove 9 is arranged on the top surface of the rotating block, a thrust bearing 10 is arranged in the mounting groove, a shaft collar of the thrust bearing is fixedly connected with the screw rod, a seat ring of the thrust bearing is arranged in the mounting groove, an annular limiting groove 11 is further arranged on the peripheral surface of the rotating block, and the inner side of the limiting ring is positioned in the annular limiting groove.
The detachable press-fitting mechanism provided by the utility model has the advantages that the press-fitting of workpieces is realized through the arrangement of the parts such as the fixed sleeve, the rotating block and the like, compared with the existing press-fitting mechanism, the mechanism is simpler, the rotating block structure is more stable, the damage is not easy in the press-fitting process, the reliability is high, and the disassembly and the installation are convenient. Simultaneously, set up the rotor in the storage tank of fixed cover with liftable for the rotor can promote the work piece more smoothly, prevents that the phenomenon that the work piece one side aligns, the opposite side misalignment and block from appearing in the pressure equipment in-process, and it is very convenient to use. In addition, the self-locking function is realized through the arrangement of the rotating block, the fixed sleeve, the thrust bearing, the screw rod and other parts, and the phenomenon of workpiece rollback can be effectively prevented.
During press fitting, an operator rotates the screw rod through the hand wheel, so that the bottom end of the screw rod moves downwards until the rotating block at the bottom end is in contact with a workpiece. In the descending process, the rotating block rotates along with the screw rod under the drive of the screw rod and the fixed sleeve.
After the rotating block is contacted with the workpiece, the rotating block gradually moves upwards along the accommodating groove under the reaction force of the workpiece until the top end of the rotating block is contacted with the top wall of the accommodating groove.
After the top end of the rotating block is contacted with the fixed sleeve, the screw rod can transmit pressure to the workpiece through the thrust bearing and the rotating block. In the initial stage, the rotating block still rotates due to the small pressure, but the rotating speed of the rotating block gradually decreases due to the friction action of the workpiece on the rotating block. In this process, a dynamic balance is gradually formed among the screw rod, the rotating block and the workpiece.
When the screw rod continuously descends, the pressure of the screw rod on the rotating block and the workpiece gradually increases, and the rotating block is gradually and tightly attached to the workpiece under the action of the workpiece and stops rotating. Because the press-fit mechanism is in press-fit, the workpiece is clamped due to the fact that the push bias and the angle misalignment are frequently generated, and the detachable press-fit mechanism is connected with the screw rod not directly but through the thrust bearing, and is in clearance fit with the thrust bearing race.
In addition, when the press fitting is stopped, the internal workpiece has a rollback phenomenon, the rollback force can reach hundreds of kilograms, after adopting the structure of the rotating block, the rollback force of the workpiece can be converted into the rotating force of the thrust bearing, and the precondition of bearing rotation must push the screw rod to reversely rotate, so that an interlocking function exists.
The fixed sleeve and the limiting ring at the bottom end of the fixed sleeve are used for limiting the rotating block and preventing the rotating block from falling off from the accommodating groove of the fixed sleeve. The annular limiting groove on the periphery of the rotating block can move up and down in the accommodating groove for a certain distance.
Preferably, the detachable pressing mechanism of the embodiment comprises a mounting plate 12, and a supporting column 13 with the top end fixedly connected with the mounting plate is arranged on the mounting plate.
The installation plate and the support column are arranged, so that the installation of components such as a screw rod sleeve, a screw rod and the like is realized.
The top end of the screw rod sleeve is fixedly arranged on the bottom surface of the mounting plate through a bolt, and the top end of the screw rod passes through a perforation on the surface of the mounting plate and is connected with the hand wheel.
Preferably, the detachable pressing mechanism of the present embodiment is a thrust ball bearing.
The thrust ball bearing can effectively reduce friction between the screw rod and the rotating block, and meanwhile, transmission of thrust is realized.
Preferably, in the detachable pressing mechanism of this embodiment, the handle 14 is provided at the edge of the hand wheel.
The arrangement of the handle facilitates the operator to rotate the hand wheel.
Preferably, the detachable pressing mechanism of this embodiment includes two fixing blocks 15, and the two fixing blocks are fixedly connected by bolts.
This setting has made things convenient for operating personnel to the installation of fixed cover and dismantles.
