The utility model discloses a parallel arrangement's top board and holding down plate to set up the connecting rod between top board and holding down plate, drive the holding down plate motion through the motion of nut on the connecting rod external screw thread and impose pressure to the spindle nose, just steadily extrude the running roller very easily. Be the form that the combination of two semi -ring shape clamp plates formed, easy to assemble and extracting tool with the top board design. The utility model discloses simple to operate, the location is accurate, the extrusion pressure is steady. And the utility model discloses simple to use, processing ease have reduced the use of manpower, material resources, have reduced cost of maintenance, make overhaul more convenient.
Description
Technical field
The utility model belongs to running roller repair apparatus technical field, is specifically related to a kind of running roller extracting tool.
Background technology
Running roller is parts common in flour mill's production equipment, running roller and axle generally are interference fit, owing to entering the reason such as impurity or rust corrosion after operation a period of time, make running roller tightr with coordinating of axle, break down need to carry out field-strip time, running roller and axle are difficult to separate.In prior art, use draws horse to dismantle more, but draws horse to be easy to cause the damage of drawing horse self and running roller because pullout forces is too concentrated.Therefore a kind of specific purpose tool is just sought after to dismantle running roller.
Utility model content
The purpose of this utility model is to provide a kind of running roller extracting tool, solves in prior art to use to draw horse to dismantle running roller due to the too concentrated problem being easy to cause running roller to damage of pullout forces.
The technical scheme that the utility model adopts is: a kind of running roller extracting tool, comprise top board and lower platen, top board and lower platen are parallel to each other and are oppositely arranged, and top board and lower platen are connected with the connecting rod of the spacing that can regulate top board and lower platen.
Feature of the present utility model is also:
Top board is made up of two block pressur plate a, and pressing plate a is semi-circular plate, is diametrically connected with contiguous block outside the two ends of pressing plate a, and two block pressur plate a are connected by bolt and nut a at contiguous block place.
Lower platen is square.
Connecting rod is provided with four, and four connecting rods are symmetrical centered by the center of top board.
One end and the top board of connecting rod are affixed, and the other end of connecting rod is flexibly connected with lower platen through after lower platen, and connecting rod one section of coordinating with lower platen is provided with external screw thread.
The position that connecting rod is connected with lower platen is provided with nut b, and nut b is positioned at the side away from top board.
The beneficial effects of the utility model are: a kind of running roller extracting tool of the present utility model, by the top board that be arranged in parallel and lower platen, and connecting rod is set between top board and lower platen, drive lower platen motion to press to spindle nose by the motion of nut on connecting rod external screw thread, be easy to just running roller steadily be extruded.Top board is designed to the form that two semi-circular pressing plates combine, be easy for installation and removal instrument.The utility model is easy for installation, accurate positioning, extrusion pressure are steady.And the utility model uses simple, processing ease, decreases the use of human and material resources, reduces maintenance cost, make maintenance convenient.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of running roller extracting tool of the utility model;
Fig. 2 is the structural representation of a kind of running roller extracting tool of the utility model top board.
In figure, 1. top board, 1-1. pressing plate a, 1-2. contiguous block, 2. lower platen, 3. bolt, 4. nut a, 5. connecting rod, 6. nut b.
Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the utility model is described in further detail:
A kind of running roller extracting tool of the present utility model, as shown in Figure 1 and Figure 2, comprise top board 1 and lower platen 2, top board 1 and lower platen 2 are parallel to each other and are oppositely arranged, and top board 1 and lower platen 2 are connected with the connecting rod 5 of the spacing that can regulate top board 1 and lower platen 2.Top board 1 is made up of two block pressur plate a1-1, and pressing plate a1-1 is semi-circular plate, is diametrically connected with contiguous block 1-2 outside the two ends of pressing plate a1-1, and two block pressur plate a1-1 are connected by bolt 3 and nut a4 at contiguous block 1-2 place; Lower platen 2 is preferably designed to square.Connecting rod 5 is provided with four, and four connecting rods 5 are symmetrical centered by the center of top board 1.One end and the top board 1 of connecting rod 5 are affixed, and the other end of connecting rod 5 is flexibly connected with lower platen 2 through lower platen 2, and connecting rod 5 one section of coordinating with lower platen 2 is provided with external screw thread.The position that connecting rod 5 is connected with lower platen 2 is provided with nut b6, and nut b6 is positioned at the side away from top board 1.
In use, first, make running roller pass the middle circular hole of two block pressur plate a1-1, then use bolt 3 and nut a4 to be tightened by two block pressur plate a1-1, two block pressur plate a1-1 form top boards 1 to the utility model; Then lower platen 2 is installed, allows lower platen 2 be placed on the termination of axle through connecting rod 5; Again nut b6 is installed to the external screw thread place of connecting rod 5; Finally, turn nut b6, make its external screw thread along connecting rod 5 close to the direction of top board 1, meanwhile, lower platen 2 press against spindle nose and moves to the direction of top board 1, so axle is just slowly steadily extruded, and separates with running roller.If there is the hypodynamic situation of extrusion, available sledgehammer knocks the medium position of lower platen 2.
The utility model makes top board 1 contact with running roller when mounted, can play the effect that dispersion pressure is exerted oneself like this, and running roller is steadily extruded.Top board 1 is designed to combined by two pieces of semi-circular pressing plates, can conveniently installs.Certainly, according to the difference of roller diameter, the Circularhole diameter in the middle of top board 1 is also designed to different sizes thereupon.
The utility model is easy for installation, accurate positioning, extrusion pressure are steady.And the utility model uses simple, processing ease, decreases the use of human and material resources, reduces maintenance cost, make the maintenance of pump convenient.
