Abstract
The utility model discloses an assembling device for an automobile air conditioner fin mould hob. The assembling device comprises a bottom plate, a central spindle and a hob. The hob comprises a flange plate and a ring-shaped cutting blade. The upper end of the bottom plate is fixedly connected with a hob fixing base which is fixedly connected with the central spindle. A key groove is arranged in the hob and matched with a rotation stop pin on the central spindle. A pressure device is arranged at the upper end of the central spindle and comprises a plane pressing wheel connected with the central spindle in a threaded mode, and a steel ball holder which can be movably arranged on the central spindle. Through grooves are respectively arranged in the plane pressing wheel and the steel ball holder. Positions of the through grooves correspond to a position of a bolt hole in the flange plate of the hob. A plurality of steel balls are arranged between the steel ball holder and the plane pressing wheel. According to the assembling device, the hob can be easy to assemble, assembling time is short, and flatness can be adjusted within 0.003mm. In addition, each part of the hob is not dislocated and deformation of a flange is avoided.
Description
Technical field
The utility model relates to a kind of assembling device, relates in particular to a kind of assembling device of air conditioning for automobiles fin die hobboing cutter.
Background technology
At present, air conditioning for automobiles fin die hobboing cutter comprises lower flange and ring cutting blade, and the flat-nose pliers clamping is adopted in its assembling usually, then directly uses the method for die nut tighten the screws, and there is the problem of two aspects in this kind assembly method:
1, flat-nose pliers belongs to the heavy load chucking power, can cause the distortion of hobboing cutter ring flange, can cause after testing about flange distortion 0.02-0.05mm;
2, six interior angle screws of assembling usefulness are the dextrorotation direction, in rundown process, can cause lower flange, the dislocation of ring cutting blade, and in case dislocation, the fin of producing can produce ripple distortion, and upper bottom knife edge of a knife cutting-in is inconsistent, has a strong impact on hobboing cutter service life.
The utility model content
The purpose of this utility model is for the problems referred to above, a kind of assembling device of air conditioning for automobiles fin die hobboing cutter is provided, adopt the flat-nose pliers clamping with the assembling that solves air conditioning for automobiles fin die hobboing cutter, then directly tighten the problem that easily causes flange distortion with die nut, and the problem that goes up lower flange, the dislocation of ring cutting blade.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of assembling device of air conditioning for automobiles fin die hobboing cutter, comprise base plate, mandrel and hobboing cutter, described hobboing cutter comprises ring flange and endless chipping, the upper end of described base plate is fixedly connected with the hobboing cutter holder, described hobboing cutter holder is fixedly connected with mandrel, have keyway on the described hobboing cutter, described keyway matches with spline pin on being arranged on mandrel, described mandrel upper end is provided with pressure apparatus, described pressure apparatus comprises the plane contact roller that is connected with mandrel thread and is removably set on ball retainer on the mandrel, all have groove on described plane contact roller and the ball retainer, the position of described groove is corresponding with the bolt hole position on the ring flange of hobboing cutter, is provided with a plurality of steel balls between described ball retainer and the plane contact roller.
Further, have installing hole on the described base plate, be convenient to install and fix.
Further, described steel ball is 6, is evenly arranged.
Further, described plane contact roller radially has through hole and a dismountable spanner that is provided with.
The beneficial effects of the utility model are that the assembling device of described air conditioning for automobiles fin die hobboing cutter is simple in structure, be easy to realize, and cost of manufacture is low; Adopt the utility model can easily assemble hobboing cutter, the time is short; And flatness is adjustable in the 0.003mm, and in addition, each parts of hobboing cutter can not produce dislocation, and have avoided flange distortion.
Description of drawings
Fig. 1 is the front view of the assembling device of the utility model air conditioning for automobiles fin die hobboing cutter;
Fig. 2 is the top view of the assembling device of the utility model air conditioning for automobiles fin die hobboing cutter.
Among the figure:
1, base plate; 2, spline pin; 3, spanner; 4, plane contact roller; 5, steel ball; 6, mandrel; 7, ball retainer; 8, ring flange; 9, annular blade; 10, hobboing cutter holder; 11, soket head cap screw.
The specific embodiment
Further specify the technical solution of the utility model below in conjunction with accompanying drawing and by the specific embodiment.
Please refer to Figure 1 and Figure 2, in present embodiment, a kind of assembling device of air conditioning for automobiles fin die hobboing cutter, comprise base plate 1, mandrel 6 and hobboing cutter, described hobboing cutter comprises ring flange 8 and endless chipping 9, have installing hole on the described base plate 1, its upper end is fixedly connected with hobboing cutter holder 10, described hobboing cutter holder 10 is fixedly connected with mandrel 6, have keyway on the described hobboing cutter, described keyway matches with spline pin 2 on being arranged on mandrel 6, described mandrel 6 upper ends are provided with pressure apparatus, described pressure apparatus comprises the plane contact roller 4 that is threaded with mandrel 6 and is removably set on ball retainer 7 on the mandrel 6, all have groove on described plane contact roller 4 and the ball retainer 6, the position of described groove is corresponding with the bolt hole position on the ring flange of hobboing cutter 8, has been evenly arranged 6 steel balls 5 between described ball retainer 7 and the plane contact roller 4, described plane contact roller 4 radially have through hole and a dismountable spanner 3 that is provided with.
During assembling, base plate 1 is fixed on the platform, spanner 3 is installed on the plane contact roller 4, thereby driving plane contact roller 4 by rotating spanner 3 rotates, plane contact roller 4 is threaded with mandrel 6, so that plane contact roller 4 moves down when rotating, produce a downward pressure, recycling ball retainer 7 transfers the pressure on the ring flange 8 of hobboing cutter, thereby each parts of hobboing cutter are compressed, so that each parts of hobboing cutter can not produce dislocation, the steel ball 5 that arranges between plane contact roller 4 and the ball retainer 7, being in order to the force of sliding friction on the plane is converted into the force of rolling friction of six points, is that available inner hexagon spanner is tightened six soket head cap screws 11 successively after each parts of hobboing cutter compress; Such as the condition license, ring flange 8 surface planarities of the most handy amesdial check hobboing cutter are finely tuned with inner hexagon spanner.Utilize this device can easily assemble a secondary hobboing cutter, the time is short, and flatness is adjustable in the 0.003mm.
Above embodiment has just set forth basic principle of the present utility model and characteristic; the utility model is not limited by above-described embodiment; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various variations and change, and these variations and change all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
