Description
Technical field
The present invention relates to mechanical processing technique equipment, especially bracket milling bottom surface, borehole drill construction.
Background technology
Bearing is the machine components of using always, and its is porose with parallel with axially bored line base plate generally, is useful on the hole of hold-down support on the base plate.Preceding bearing, rear support as the 6NF series jet-air rice polisher that consumption is big in the paddy process equipment.The base plate bottom surface of the bearing generally hole on processing, base-plate on the milling machine will get out on drilling machine.But no matter be or on drilling machine, hole at milling flat on the milling machine, all must make the plane that processes parallel with the axially bored line of bearing top, with the axially bored line symmetry of bearing top, just on the bearing lateral opening axis in by bearing baseplane center line and the plane vertical with the bottom surface.The group centerline hole that gets out in the bearing bottom surface is also in this plane.Locate with an end face in bearing upper surface hole axis, hole and one side of base-plate when processing the base-plate bottom surface in the past.Because general bearing is a foundry goods, its length and width all have error, reach the axially bored line symmetry with the bearing top so can not guarantee the bottom surface that processes and hole.
Summary of the invention
The purpose of this invention is to provide a kind of bracket milling bottom surface, borehole drill construction, be used to process the bottom surface of bearing and the hole on the bottom surface.Reach axis lateral opening on the bearing in by bearing bottom center line and the plane vertical with the bottom surface.The group centerline hole that gets out in the bearing bottom surface is also in this plane.
The technical solution adopted for the present invention to solve the technical problems is: the location, one side with the bearing bottom surface is become with the both sides of bearing bottom surface locate automatically.
Bracket milling bottom surface, borehole drill construction is by right baffle-plate, regulate bolt, the dextrorotation slide block, pressing plate, stud, support column, body, bushing plate, mandrel, the groove cover plate, the drill jig cover, left-handed slide block, right baffle plate, leading screw, rotating cylindrical and retaining pad are formed, it is characterized in that: dextrorotation slide block and left-handed slide block are contained in respectively on the corresponding double-screw bolt at leading screw two ends, dextrorotation slide block and left-handed slide block are contained in the groove of body front together with leading screw, right baffle-plate is contained in the left side of the groove of body front with bolt, the hole of right baffle plate cooperates the right that is contained in the groove of body front with bolt with the small column of leading screw right-hand member, leading screw is blocked by right baffle-plate and right baffle plate at its axis direction, less clearance is arranged, the groove cover plate be contained in sunk screw the body front groove above, rotating cylindrical is contained in the hole of leading screw small end; The helical pitch equidirectional of dextrorotation slide block and left-handed slide block internal thread is opposite, the adjusting bolt is contained in the top of dextrorotation slide block and left-handed slide block respectively and locks with corresponding nut, and two regulate the front end face of bolts to passing through the mandrel axis plane symmetry vertical with the front end face of body; Have dismountable bushing plate of location structure to be contained in the front end face of body, drill jig is sleeved on the bushing plate; Mandrel is contained on the body with vertical above the groove cover plate, and the endoporus of bearing is contained on the mandrel above the body, the base plate of bearing with pressing plate, support column, stud and corresponding plain washer and nut be pressed on the groove cover plate+.
The advantage of this bracket milling bottom surface, borehole drill construction is: owing to adopt the location structure of advance and retreat simultaneously, just can make the base plate of a plurality of bearings, not being subjected to it the orientation size is inconsistent influences, and the realization centre of location is in the fixed position.Mechanism structure is simple, low cost of manufacture.
