Description
Technical field
The utility model belongs to the machining technique field, particularly relates to a kind of thin wall shaft bearing hole processing and positioning device.Be applicable to that hole wall is thin, the processing of the bearing block class part of mutability.
Background technology
The utility model technology relate to a kind of hole wall thin, than the bearing block of mutability, we know, for the part of bearing block class; Common processing method is on horizontal boring machine, horizontal Machining centers, to process; But, be characterized in that hole wall is thinner, is not easy to clamping for the bearing block on the continuous casting machine fan-shaped segment frames; If adopting conventional method processes on horizontal boring machine, horizontal Machining centers; Processing cost is high, and the control of the machining accuracy in hole is very difficult, and we a large amount of waste products occurs in initial processing.Through homemade this covering device on lathe; Change clamping power radially into axial clamping power, again the hole is processed, after machining; There is not distortion; The hole precision guarantees that easily the bearing block that we processed now all adopts this method, on accuracy guarantee, cost and efficient, all has greatly improved in the past.
Summary of the invention
The purpose of the utility model is to provide a kind of thin wall shaft bearing hole processing and positioning device, changes into through the radially clamping power that the hole is received and receives axial clamping power, has solved thin, the yielding bearing block class part centralized positioning complicacy of hole wall, is difficult for processing problems accurately.
The utility model comprise balancing weight 1, balancing weight fastening bolt 2, pressing plate 3, pressing plate fastening bolt 4, position block 5, locating piece fastening bolt 6,, disk body 7, back-up block 8, bearing block 9.
Disk body 7 one sides are connected through bolt with lathe spindle; The opposite side of disk body 7 is connected with bearing block 9 through position block 5, with pressing plate 3, pressing plate fastening bolt 4, back-up block 8 bearing block 9 is fastened on the disk body 7 along axis direction, each hole in the bearing block is processed again.Balancing weight 1 usefulness balancing weight fastening bolt 2 is fixed on the disk body 7.
Hole Φ A, hole Φ B are coaxial vertical with left end face on disk body 7, require under an installation way, to machine (as shown in Figure 2), and bearing block 9 bottom surface locating slots are connected with position block 5, according to the center of bearing block 9 and the dimensional requirement of bottom surface locating slot.
Hole Φ A, hole Φ B are coaxial with its right end face on the disk body; Requirement machines (as shown in Figure 1) under an installation way; The side bus of alignment pin and disk body center line coplane; Just in same plane,, can adjust the size of two alignment pin spacing H according to halfbody part dimension to be processed.
Alignment pin is the step alignment pin, and spring is equipped with at the rear portion, through screw in compression, is in the state of upspringing before the clamping.
The localization method of the utility model device is to be connected with bearing block 9 bottom surface locating slots through position block 5, through pressing plate 3, pressing plate fastening bolt 4, back-up block 8 bearing block is fastened on the disk body 7 along axis direction.Like this, through the above-mentioned this method bearing block 9 that is installed, accomplished centralized positioning, and the pressing plate direction is axially press-fiting along bearing block 9.
The utlity model has following advantage: the one, the bearing block that is installed saves time, laborsaving, can reach quick location; The 2nd, the part quality that processes is reliable, and high conformity satisfies required precision; The 3rd, through this processing method, the hole does not have distortion, saves tool type, and completion for boring, has reduced processing cost with car.
