Description
Technical field
The utility model belongs to grinding machine equipment technical field, is related to a kind of grinder center frame.
Background technology
When grinding machine is polished the columnar workpiece periphery wall with greater depth, the cutter head of grinding machine stretches out and supported from sidepiece
Lean against on Workpiece periphery wall, therefore cutter head can produce horizontal applied force to workpiece, the active force can cause the lateral deformation of workpiece, shadow
Polishing precision is rung, and when Workpiece length is larger, therefore the gravity of workpiece also results in vertical deformation, can also influence precision of polishing,
Therefore grinding machine needs centre frame to position workpiece, and the side of workpiece is resisted against typically by the located lateral seat crossed out
Portion, to offset the active force of cutter head, the bottom of workpiece is resisted against by the vertical positioning seat stretched out upwards, to support workpiece, but
It is that vertical positioning seat needs larger stroke space and the space for installing driving part when rising vertically from lower to upper, but
Grinding machine has work top, smaller with the distance between work top when workpiece is positioned on grinding machine.
Therefore above-mentioned technical problem, Chinese invention patent application (application number are directed to：201610365161.X) disclose one
Kind crankshaft grinding machine servo center frame, including bracket, locating rod one, locating rod two and 2 groups of drive components, locating rod two include tilting
Drive section, drive component include screw-drive mechanism and drive screw-drive mechanism motor, locating rod one is in direct rod shape,
The shaft horizontal distribution of locating rod one, the positioning end face vertical distribution of locating rod one, locating rod two also include supporting section, supporting section
Supporting surface be arranged to horizontal, withstanding tight block is distributed vertically, and support block horizontal distribution, two locating surfaces are in 90 ° of angles, jointly to song
Axle carries out auxiliary positioning, can prevent deformation of the bent axle under Gravitative Loads, and can prevents bent axle in the extruding force of grinder wheel
Under Light deformation, i.e., the grinder center frame by locating rod two, drive locating rod two motor and screw mandrel be obliquely installed, with reduce
To the occupancy of vertical direction spatial, but due to vertical positioning seat and workpiece against when influence for eliminating the gravity of workpiece, but such as
The feeding accuracy of measurement of the vertical positioning seat of fruit is not high enough so that vertical positioning seat is too small to the active force of workpiece, then does not have counteracting
The effect of workpiece gravity, and it is excessive if effect run counter to desire, similarly, the feeding accuracy of measurement of located lateral seat is also of equal importance,
But driving the screw mandrel of vertical positioning seat and motor to be obliquely installed in above-mentioned documents, the active force of vertical positioning seat can be led
Screw mandrel and nut radial force are caused, this will increase the abrasion of screw mandrel and nut, so as to influence the feeding accuracy of measurement of vertical positioning seat,
Similarly, workpiece can produce downward frictional force in rotating at a high speed in bruting process to located lateral seat, and the frictional force also can
Cause the screw mandrel and nut radial force for driving located lateral seat, so as to increase the abrasion of the screw mandrel and nut, so as to influence horizontal stroke
Feeding accuracy of measurement to positioning seat.
The content of the invention
The purpose of this utility model is above mentioned problem be present for existing technology, it is proposed that a kind of grinder center frame, should
Grinder center frame can reduce the abrasion of the functional parts such as screw mandrel, improve the precision of the amount of feeding.
