Description

Part plane grinding tool

Technical Field

The utility model relates to a grind the frock field, especially relate to a grind frock to part plane.

Background

In the steel processing process, need grind the surface of part many times, just at this time need the workman to use handheld abrasive paper to grind the part, hold abrasive paper always and can lead to the workman tired easily, the incident easily takes place, so develop a section can replace the handheld grinding frock of abrasive paper of workman just seem to be especially necessary.

Object of the Invention

The utility model relates to a part plane grinds frock is the instrument that is used for replacing the manpower to grind workpiece surface.

SUMMERY OF THE UTILITY MODEL

The utility model provides a frock is ground on part plane, the on-line screen storage device comprises a base, the base is a rectangular frame, the fixed motor and the reduction gear that is provided with of right-hand member of base, reduction gear power input shaft and motor spindle are connected, and reduction gear power output shaft front end fixedly connected with crank, the crank is perpendicular with reduction gear power output shaft, the one end of keeping away from reduction gear power output shaft on the crank is rotated and is connected with the stock, the stock is parallel with the crank, the one end of keeping away from reduction gear power output shaft on the stock is rotated and is connected with the steel sheet, the steel sheet is perpendicular with the axis extending direction of stock, be fixed with the log on the steel sheet, and log.

Preferably, the lower end of the long rod is provided with a plurality of hanging rings which are distributed along the axial direction of the long rod, and at least one lower part of the plurality of hanging rings is detachably connected with a balancing weight.

Preferably, the lower end face of the rectangular frame is provided with a bottom plate.

Preferably, the bottom plate on along left right direction evenly distributed have a plurality of first nuts, the axis of first nut extends along vertical direction, the top of bottom plate is equipped with fixing device, fixing device includes double-screw bolt, second nut and clamp plate, the vertical setting of double-screw bolt and lower extreme and first nut threaded connection, the double-screw bolt upper end run through the clamp plate and with clamp plate sliding connection, the second nut be located the clamp plate top and with double-screw bolt threaded connection.

The beneficial effects lie in that, the crank turns into the removal of stock along left and right direction with the rotation of speed reducer power output shaft, and abrasive paper grinds the workpiece surface along left and right direction under the drive of stock, and rings can increase the overdraft of abrasive sheet through suspending the heavy object in midair, make the grinding effect better.

Detailed Description

The present invention will be further described with reference to the specific embodiments, as shown in fig. 1 to 4, a part plane grinding tool includes a base 1, the base 1 is a rectangular frame, a bottom plate 2 is disposed on the lower end surface of the rectangular frame, the bottom plate 2 is disposed to prevent the workpiece from contacting the ground and being scratched by the ground impurities, a plurality of first nuts 3 are uniformly distributed on the bottom plate 2 along the left and right direction, the axes of the first nuts 3 extend along the vertical direction, a fixing device is disposed above the bottom plate 2, the fixing device includes a stud 13, a second nut 14 and a pressing plate 15, the stud 13 is vertically disposed and has a lower end in threaded connection with the first nut 3, the upper end of the stud 13 penetrates through the pressing plate 15 and is in sliding connection with the pressing plate 15, the second nut 14 is disposed above the pressing plate 15 and is in threaded connection with the stud 13, a motor 4 and a speed reducer 5 are fixedly disposed at the right, the motor 4 and the reducer 5 are the prior art, which is not described herein any more, the power input shaft of the reducer 5 is connected with the main shaft of the motor 4, the front end of the power output shaft of the reducer 5 is fixedly connected with a crank 6, the crank 6 is perpendicular to the power output shaft of the reducer 5, one end of the crank 6, which is far away from the power output shaft of the reducer 5, is rotatably connected with a long rod 7, the long rod 7 is parallel to the crank 6, along with the rotation of the power output shaft of the reducer 5, the crank 6 drives the long rod 7 to rotate in a vertical plane extending along the left-right direction, the lower end of the long rod 7 is provided with a plurality of hanging rings 8 axially distributed along the long rod 7, at least one hanging ring 8 of the hanging rings 8 is detachably connected with a counterweight 9, if the surface roughness of a part to be processed is large, keep away from 5 power output shaft's of reduction gear one end rotation on stock 7 and be connected with steel sheet 10, the axis extending direction of stock 7 is perpendicular with steel sheet 10, is fixed with log 11 on the steel sheet 10, and the diameter of log 11 is greater than the diameter of stock 7, and 11 axis extending directions of log are perpendicular with 7 axis extending directions of stock, and the winding has abrasive paper 12 on the log 11, and abrasive paper 12 is fixed to on the log 11 through the nail

The specific working process is as follows: as shown in fig. 3: when needs grind the part, place the part on bottom plate 2, the vertical setting of double-screw bolt 13 and lower extreme and 3 threaded connection of first nut, double-screw bolt 13 upper end run through clamp plate 15 and with clamp plate 15 sliding connection, clamp plate 15 compresses tightly the part, second nut 14 is located 15 tops of clamp plate and with double-screw bolt 13 threaded connection, then fix abrasive paper 12 to log 11 on, hang in midair the weight increase piece 9 and increase the holding down force of stock 7 on rings 8, open motor 4, power transmits for crank 6 after 5 speed reductions of reduction gear, crank 6 turns into the removal of stock 7 along the left and right directions with 5 power output shaft's of reduction gear rotation, abrasive paper 12 grinds the workpiece surface along the left and right directions under the drive of stock 7.
