Description
Technical field
The present invention relates to a kind of constant pressure grinding devices.
Background technology
Grinding wheel is overshooted in grinding, and the frictional force of grinding wheel transverse grinding directly influences pressure between grinding wheel and workpiece, at present
Cause constant pressure grinding cannot achieve due to being difficult to realize the stability of microfeed, in this way be easy because friction variation and
Cause the unstable of grinding force, machining accuracy is impacted.
Invention content
In view of this, the object of the present invention is to provide a kind of reliable and stable, constant pressure grinding devices of high precision machining.
The present invention is realized using following scheme：A kind of constant pressure grinding device, including the grinding carriage of grinding wheel, grinding wheel are installed
It is provided with the feed screw that driving grinding carriage moves forward feeding below frame, is provided with below grinding carriage and matches with feed screw screw thread
The nut seat of conjunction, the grinding carriage can opposing nut seat be moved forward and backward, be provided with axial line and feed screw on the nut seat
Parallel piston hole is provided with the piston being slidably matched with it in the piston hole, piston nose is provided with push grinding carriage before
The piston rod moved afterwards, piston hole rear end are connected with pressure oil pipe, pressure reducing valve are provided on pressure oil pipe.
Further, the grinding carriage bottom is provided with the fixed plate positioned at nut seat rear, is arranged in the fixed plate
Have to head on the position block of nut seat trailing flank to limit the distance of grinding carriage opposing nut seat forward movement.
Compared with prior art, the invention has the advantages that：Constant pressure grinding apparatus structure stabilization of the present invention can
It leans on, pressure is constant between holding grinding wheel and workpiece in grinding process, realizes stable microfeed, in this way can be to avoid by grinding
It wipes power variation and causes the unstable of grinding force；Ensure that the dimensional accuracy of workpiece, efficiency increase, and it is super negative to can avoid grinding wheel
Lotus, safe operation.
To make the objectives, technical solutions, and advantages of the present invention more comprehensible, specific embodiment and phase will be passed through below
Attached drawing is closed, invention is further described in detail.
Description of the drawings
Fig. 1 is inventive embodiments organigram；
Figure label explanation：100- grinding carriages, 110- grinding wheels, 120- fixed plates, 121- limited blocks, 200- feed screws,
300- nut seats, 310- piston holes, 320- pistons, 330- piston rods, 340- pressure oil pipes, 341- pressure reducing valves, 400- workpiece.
Specific implementation mode
As shown in Figure 1, a kind of constant pressure grinding device, including the grinding carriage 100 of grinding wheel 110 is installed, under grinding carriage 100
Side is provided with the feed screw 200 that driving grinding carriage 100 moves forward feeding, and the main shaft of feed screw and servo motor coaxially connects
Connect, the lower section of grinding carriage 100 be provided with the nut seat of feed screw screw-thread fit 300, the grinding carriage 100 can opposing nut seat
300 are moved forward and backward, and the piston hole 310 of axial line parallel with feed screw 200, the piston are provided on the nut seat 300
The piston 320 being slidably matched with it is provided in hole 310, piston nose is provided with the piston rod for pushing grinding carriage to be moved forward and backward
330, piston hole rear end is connected with pressure oil pipe 340, and pressure reducing valve 341 is provided on pressure oil pipe；Grinding attachment of the present invention passes through
Pressure oil pushes piston motion, drives grinding carriage to be ground close to workpiece by piston rod, when ensureing grinding, grinding wheel is with certain
Force to workpiece（Or workpiece is forced with certain to grinding wheel）, and keep in grinding process between grinding wheel and workpiece pressure not
Become, the pressure of pressure oil can be changed in adjustment pressure reducing valve, and grinding force is also with variation.
In the present embodiment, 100 bottom of the grinding carriage is provided with the fixed plate 120 positioned at 300 rear of nut seat, described
Be provided with to head on the position block 121 of 300 trailing flank of nut seat in fixed plate 120 with limit grinding carriage opposing nut seat to
The distance of preceding movement, the present invention realize stable microfeed by the way that position block is arranged；Stable microfeed can be as possible
So that the frictional force in traverse feed system is reduced, can cause the unstable of grinding force to avoid being changed by friction in this way；
The dimensional accuracy for ensureing workpiece, ensures that constant pressure grinding is carried out under optimum amount, and efficiency increases, and it is super to can avoid grinding wheel
Load, safe operation.
Above-listed preferred embodiment, has been further described the object, technical solutions and advantages of the present invention, is answered
Understand, the foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
With within principle, any modification, equivalent replacement, improvement and so on should all be included in the protection scope of the present invention god.
