Abstract
The utility model discloses a chain dismounting device, including the frame of rectangle, be equipped with a plurality of pinholes in the middle of the frame, the frame four corners is equipped with the installation piece, is equipped with the screw hole on the installation piece, the pole of screwing has four groups, and the pole of screwing includes circular shape handle and branch, and the branch end is fixed on knob, be equipped with the external screw thread on the branch, the branch front end passes the screw hole of installation piece, with installation piece threaded connection, the branch front end is equipped with the convex fixture block, the compact heap is the rectangle structure, is equipped with the convex recess on the compact heap, and is fixed with the convex fixture block cooperation of branch front end. The utility model discloses a compact heap can compress tightly the chain, and in the pinhole in the middle of the insertion machine frame can be aimed at to the round pin axle of chain, the degree of depth of pinhole subtracted a chain plate thickness for the length of round pin axle, guarantees the round pin axle and can not pounded out the link joint.
Description
Technical field
The utility model relates to a kind of provision for disengagement, particularly a kind of chain provision for disengagement.
Background technology
Chain drive is mechanically operated a kind of important form.Driving chain generally adopts bushroller chain, is made up of inner plate, outer plate, sleeve and roller, and bearing pin and outer plate, sleeve and inner plate are all interference fit, are connected between each chain link by outer plate, and sleeve freely can rotate on bearing pin.After a long time use, chain easily weares and teares and occurs elongation and the relaxation of chain, affects the accuracy that chain drive coordinates, affects the normal work of plant equipment.When more renewing chain, the joint number of new chain is not mated with old chain bar, usually needs new chain dismantling to recombinate.
In prior art, the nut of bearing pin is normally a bit larger tham in chain dismounting at the multiple internal diameter of chain underlay, and sample punching is placed on bearing pin stably, then knocks sample punching, until the upper surface of bearing pin is equal with another sheet outer plate end face of below with hammer.And during practical operation, the nut that chain pads below is difficult to aim at the bearing pin of chain, sometimes there will be in hammering process and jumped by padded nut, or sample charges and attacks cunning, hammer knocks the problems such as hand.The more important thing is, in hammering process, be difficult to control sample punching just in time bearing pin upper surface be flushed to the position equal with the upper surface of another sheet outer plate of below, sometimes bearing pin is directly gone out, and bearing pin is difficult to reinstall after going out carrier bar.
Summary of the invention
The purpose of this utility model is to solve the problem, and provides a kind of structure simple, can fix chain, and accurately pin roll end face is flushed to the chain provision for disengagement equal with outer plate end face.
For this reason, the technical solution of the utility model is: a kind of chain provision for disengagement, comprises the frame of rectangle, is provided with some pin-and-holes in the middle of frame; Frame corner is provided with mounting blocks, and mounting blocks is provided with screwed hole; Screw bar and have four groups, screw bar and comprise circular handle and pole, pole end is fixed on knop; Pole is provided with external screw thread, and pole front end, through the screwed hole of mounting blocks, is threaded with mounting blocks; Pole front end is provided with convex fixture block; Compact heap is rectangular configuration, and compact heap is provided with convex grooves, coordinates fixing with the convex fixture block of pole front end.
Further, the pin-and-hole in the middle of described frame is in horizontal, and the aperture of pin-and-hole is corresponding with the pin diameter of chain; The degree of depth of pin-and-hole is the difference of bearing pin length and monolithic thickness of link plates, bearing pin displacement when namely bearing pin upper surface is equal with the upper surface of below outer plate.
Frame of the present utility model four angles are all equipped with and are screwed bar, rotate knop and compact heap can be made to move forward and backward, thus chain can compress by relative compact heap; The bearing pin of chain can be aimed at and insert in the middle pin-and-hole of frame, the degree of depth of pin-and-hole is the thickness that the length of bearing pin deducts one block of carrier bar, when ensureing that bearing pin is flushed to bottom pin-and-hole, the upper surface of bearing pin is just in time equal with the end face of below outer plate, ensures that bearing pin can not be pounded out carrier bar.
Accompanying drawing explanation
Be described in further detail below in conjunction with accompanying drawing and embodiment of the present utility model.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the A-A generalized section of Fig. 1.
Fig. 3 is operating diagram of the present utility model.
Fig. 4 is the B-B generalized section of Fig. 3.
Fig. 5 of the present utility modelly knocks schematic diagram.
Be labeled as in figure: frame 1, pin-and-hole 2, chain 3, bearing pin 31, mounting blocks 4, handle 5, pole 6, convex fixture block 61, compact heap 7, the punching of convex grooves 71,8 sample, 9 hammers.
Detailed description of the invention
See accompanying drawing.The present embodiment comprises the frame 1 of rectangle, 6 pin-and-holes 2 are provided with in the middle of frame, respectively corresponding 5 points single, 5 points double, 6 points of single, 6 points of double and 1 cun of single, 1 cun of double bearing pin sizes, the degree of depth of pin-and-hole 2 is the thickness that the length of chain 3 bearing pin deducts one block of carrier bar; Frame corner is provided with mounting blocks 4, and mounting blocks is provided with screwed hole; Screw bar and have four groups, screw bar and comprise circular handle 5 and pole 6, pole end is fixed on knop; Pole is provided with external screw thread, and pole front end, through the screwed hole of mounting blocks 4, is threaded with mounting blocks; Pole 6 front end is provided with convex fixture block 61; Compact heap 7 is rectangular configuration, and compact heap is provided with convex grooves 71, coordinates fixing with the convex fixture block of pole front end.
During the present embodiment work, lie in frame by chain 3, bearing pin 31 is perpendicular to frame face; During placement, make the bearing pin pounded out and corresponding pin-and-hole 2 co-axially align, rotate the knop 5 of both sides, the compact heap 7 screwing bar front end fixing is moved to chain direction, compresses chain; Finally bearing pin is aimed in sample punching 8, then knock sample punching with hammer 9, until bearing pin is knocked bottom pin-and-hole, chain 3 has just been taken apart.
