Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the top view of Fig. 1.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, detailed construction of the present utility model is further described.
As shown in drawings: a kind of two leaf cycloidal impeller cap iron tools, comprise pedestal 1, first intermediate plate 2, locating shaft 3, connecting rod 4, second intermediate plate 7, pedestal 1 is inverse-T-shaped structure, pedestal 1 bottom surface is provided with installing hole 1-1, pedestal 1 is provided with the first groove 1-2 topmost, the front end of locating shaft 3 is placed on the middle part of pedestal 1, and tangent with pedestal 1, and point of contact is two; First intermediate plate 2 is positioned at the left side of locating shaft 3, and with locating shaft 3 compact siro spinning technology, locating shaft 3 is trapped among centre by the first intermediate plate 2 and pedestal 1, is provided with the first screwed hole in the first intermediate plate 2; One section of screw thread is all respectively established at the two ends, left and right of connecting rod 4, and the left end screw thread of connecting rod 4 passes from the first screwed hole, and the right-hand member screw thread of connecting rod 4 passes from the first groove 1-2, and the right-hand member top of connecting rod 4 is provided with nut 5; Second intermediate plate 7 is positioned on the right-hand member upper surface of pedestal 1.
First intermediate plate 2 is arc-shaped structure, in the first intermediate plate 2 any cross section centre point therewith in plane the centre point of locating shaft 3 identical, locating shaft 3 can be fixed between the first intermediate plate 2 and pedestal 1 by the first intermediate plate 2 tightly.
The bottom of the second intermediate plate 2 is also provided with pad 6, pad 6 is positioned at the front side of pedestal 1, and pad 6 is adjustable for height layered laminate structure, the convenient height regulating pad 6, the effect of pad 6 made for the second intermediate plate 7 moment keep level, increases the stability of the second intermediate plate 7; Second intermediate plate 7 is provided with the second screwed hole 7-1 of strip, supporting bolt assembly 8 is provided with in second screwed hole 7-1, adjusting bolt assembly 8 is in the position of the second screwed hole 7-1, and the position of adjustable second intermediate plate 7, makes the second intermediate plate 7 reach the object of auxiliary fixing impeller preferably.
The front end of locating shaft 3 is provided with the second groove 3-1 passed for connecting rod 4, facilitates the taking-up of connecting rod 4 and puts into.
The quantity that two leaf cycloidal impeller cap iron tools are used for when fixing impeller is two, and two leaf cycloidal impeller cap iron tools are placed on the two ends of impeller respectively.
Operation principle of the present utility model and using method are: two leaf cycloidal impellers are generally made up of two blades, two blades have impeller installing hole, the symmetrical centre place of two blades generally also can have impeller installing hole, when impeller surface needs plane to add man-hour, installing hole in the middle of impeller is used for penetrating of locating shaft 3 rear end in two leaf cycloidal impeller cap iron tools, after the locating shaft 3 in two two leaf cycloidal impeller cap iron tools has penetrated, the distance between two two leaf cycloidal impeller cap iron tools is regulated to be optimum state, and by the installing hole 1-1 on pedestal 1, pedestal 1 is fixed on lathe, then the left end screw thread of connecting rod 4 is regulated to penetrate position in the first intermediate plate 2, then the first intermediate plate 2 is made to be close to locating shaft 3, with nut 5 from the right-hand member screw thread of connecting rod 4, and tightening nut 5, make nut 5 be close to pedestal 1 to fix, now locating shaft 3 has just been fixed, then the rear end of the second intermediate plate 7 is put in the impeller installing hole on impeller blade, according to the height of the second intermediate plate 7 rear end, select suitable pad 6 height, the second intermediate plate 7 is made to keep level, and determine the position of bolt assembly 8 in the second screwed hole 7-1, then with bolt assembly 8, second intermediate plate 7 is fixed on pedestal 1, each two leaf cycloidal impeller cap iron tools have two fixing points to impeller, two two leaf cycloidal impeller cap iron tools produce four fixing points to an impeller altogether, therefore, impeller can be firmly fixed by two leaf cycloidal impeller cap iron tools, and after the one side of impeller machines, only need right for impeller locating shaft to turn over turnback to carry out plane again and process, in switching process, because the shaft core position of the effect impeller of locating shaft 3 can not free any change or skew, thus can ensure that two leaf cycloidal impellers have higher axiality and symmetry in plane process.
