Abstract
The invention discloses a super-precision grinding machine for a disc-shaped grooved cam channel. The super-precision grinding machine comprises a motor, a motor support, a pedestal, a coupling, a bearing pedestal, free grinding grains, a baffle block, a baffle plate and a work shaft; the motor is connected with the motor support by bolts, the motor support is connected with the pedestal by bolts, and the bearing pedestal is connected with the pedestal by bolts; the coupling is connected with the motor output shaft and work shaft; the bearing pedestal supports the work shaft; a workpiece to be ground is connected with the work shaft by a key connection mode. Before grinding, the free grinding grains are filled in a disc-shaped grooved cam channel; the baffle plate is buckled on a disc-shaped grooved cam with free grinding grains, and the baffle plate and disc-shaped grooved cam are arranged on the work shaft in one time. The baffle block is connected with the work shaft in a threaded connection mode, after connecting, the baffle block props against the baffle plate to enable the baffle plate to contact with the workpiece to be ground so as to prevent the free grinding grains from splashing towards the outside in the grinding process. By means of said mode, the super-precision grinding for the disc-shaped grooved cam channel is realized.
Description
Technical field
The present invention relates to a kind of super precise grinding machine, particularly relate to a kind of super precise grinding machine of plate-like grooved cam conduit.
Background technology
At present, the grinder of plate-like grooved cam conduit mostly utilizes NC Interpolation Principle of Grinding and Cutting, adopts the emery wheel of High Rotation Speed to carry out the workpiece that interpolation feed motion is carried out in grinding.This processing mode can put program accordingly according to part shape change, and processing technology is easy to adjust, and machining accuracy retentivity is good, automaticity is high, can flexible integration processing, but be restricted due to the grinding accuracy of emery wheel, make machining accuracy be difficult to meet the requirement of superhigh precision processing.
Summary of the invention
Object of the present invention is exactly to solve the defect being at present difficult to meet superhigh precision processing request for the traditional numeric-control interpolation grinding mode on grinding plate-like grooved cam conduit surface, provides a kind of super precise grinding machine that can meet the plate-like grooved cam conduit of superhigh precision processing request.
For this reason, the present invention is by the following technical solutions: a kind of super precise grinding machine of plate-like grooved cam conduit, comprise motor, support of motor, base, shaft coupling, bearing block, free abrasive, block, baffle plate, working shaft, it is characterized in that, motor and support of motor, support of motor and base, bearing block and base all adopt bolt-connection, shaft coupling connects motor output shaft and working shaft, bearing block support works axle, workpiece to be ground and working shaft adopt key connected mode, block and working shaft adopt threaded connection mode, connect backstop and prop up baffle plate, make it to contact with to be ground, prevent from spattering outside free abrasive in process of lapping.
Before grinding starts, described free abrasive is filled in the conduit of plate-like grooved cam, described baffle plate is buckled in and is filled with on the plate-like grooved cam of free abrasive, then the two is disposablely installed on working shaft.
The abrasive particle that attrition process uses is in free state.
Due to Action of Gravity Field, free abrasive will be in the one section conduit place of plate-like grooved cam closer to base always, and its volume can block this conduit, does not fill full whole piece conduit completely again simultaneously.
The invention has the beneficial effects as follows: workpiece attrition process precision is high, superhigh precision processing request can be met.

Detailed description of the invention
Refer to Fig. 1, Fig. 2 and Fig. 3, content of the present invention is: a kind of super precise grinding machine of plate-like grooved cam conduit, comprises motor 3, support of motor 2, base 1, shaft coupling 4, bearing block 5 and 6, free abrasive 8, block 9, baffle plate 10, working shaft 11.
Motor 3 all adopts bolt-connection with support of motor 2, support of motor 2 with base 1, bearing block 5 and 6 and base 1, shaft coupling 4 connects motor output shaft and working shaft 11, bearing block 5 and 6 support works axle 11, workpiece to be ground and working shaft 11 adopt key connected mode, block 9 and working shaft 11 adopt threaded connection mode, connect backstop 9 and prop up baffle plate 10, make it to contact with to be ground, prevent from spattering outside free abrasive 8 in process of lapping.
Before grinding starts, free abrasive 8 is filled in the conduit 12 of plate-like grooved cam 7, described baffle plate 10 is buckled in and is filled with on the plate-like grooved cam 7 of free abrasive 8, then the two is disposablely installed on working shaft 11.
Due to Action of Gravity Field, free abrasive 8 will be in the one section conduit place of plate-like grooved cam 7 closer to base 1 always, and its volume can block this conduit, does not fill full whole piece conduit 12 completely again simultaneously.
After motor 3 is started working, plate-like grooved cam 7 to be ground starts to rotate around working shaft 11 axis, is in free abrasive 8 in plate-like grooved cam conduit 12 and carries out fine abrasive to conduit 12 surface under the effect of self gravitation and centrifugal force.
