Abstract

The utility model relates to a grinding device for processing a top circle on a shaft diameter of a grinder end closure. The grinding device comprises a motor, wherein, the motor is arranged on an underplate which is arranged on a tool post of a lathe; a driver is arranged on an output shaft of the motor; one side of the underplate is connected with a driven wheel device through a gripping sleeve; a layer of rubber is arranged outside a driven wheel of the driven wheel device; the driver is connected with the driven wheel through an emery tape. When in work, the driven wheel is lightly pressed on the surface of a workpiece, the motor runs at a high speed to drive the driver to rotate, and the driver drives the driven wheel to rotate for grinding through the emery tape. The grinding device has simple structure and design, the manufacturing precision is not very high, and the cost is low; the allowance of 0.3 mm is left before grinding on a large-scale workpiece, and then the grinding is acted; the working efficiency is increased by multiple times; particularly for the workpiece with high tolerance fit requirement, the operation and the control of the grinding are more easier than that of the turning; the surface roughness of the workpiece which is processed by using the grinding device can reach Ra 0.8.

Description

Grinder shell cover diameter of axle bar grinding attachment
Technical field
The utility model relates to a kind of large-scale workpiece grinding attachment, specifically a kind of grinding attachment that is used for processing grinder shell cover diameter of axle cylindrical.
Background technology
We know, the end cap diameter of axle place of present horizontal grinding machine is as the high-speed slide position, occur giving birth to heat easily when equipment is worked, grind and damage, and the requirement of its precision, surface smoothness is all very high.Use the various cutters on the common vertical lathe of present process equipment----to process at all and can't realize,, also can not reach the requirement of workpiece processing even on numerically controlled lathe, process.
Summary of the invention
The utility model is for overcoming above-mentioned the deficiencies in the prior art, provide a kind of simple in structure, cost is lower, grinding attachment that can grinding grinder shell cover diameter of axle cylindrical.
The purpose of this utility model is to adopt following technical proposals to realize: a kind of grinder shell cover diameter of axle bar grinding attachment, comprise motor, motor is installed on the base plate, motor output shaft is provided with driving wheel, base plate one side is connected with the driven pulley device by gripping sleeve, the driven pulley outside of driven pulley device is provided with one deck rubber, and driving wheel is connected with driven pulley by the abrasive band.
Described driven pulley device comprises gripping sleeve, sleeve, axle and driven pulley, and gripping sleeve is connected with sleeve, by bearing fixing axle is arranged in the sleeve, and the front end of sleeve is provided with logical lid, and the rear end is provided with stifle, and the front end of axle is fixed with driven pulley.
Described base plate is provided with elongated slot, and the electric baseboard of motor by the bottom is installed in the elongated slot on the base plate.
There is the wheel edge at the two ends of described driving wheel, and cylindrical is a sphere.
The cylindrical that contacts with rubber layer on the described driven pulley is provided with left-handed and right-handed thread.
During the utility model work, this device press-fits on the cutter platform of lathe by base plate, driven pulley is pressed in gently on the surface of workpiece, and running up by motor drives the driving wheel rotation, and driving wheel drives driven pulley rotation carrying out grinding by the abrasive band.
The beneficial effects of the utility model: structural design is simple, the accuracy of manufacture need not be too high, cost is low, can before grinding, stay the surplus of 0.3mm for large-scale workpiece, carry out grinding then, during operation can according to the size of spark judge the mill amount what, to guarantee the dimensional tolerance of workpiece, operating efficiency improves several times, especially for the demanding workpiece of tolerance fit, and easier operation of grinding ratio turning and control.The smart rugosity of the surface of the work that uses this device to process can reach Ra0.8.
Description of drawings
Fig. 1 is the utility model structural representation;
1. stifle, 2. sleeve, 3. gripping sleeve, 4. logical lid, 5. spool, 6. driven pulley, 7. base plate, 8. electric baseboard, 9. driving wheel, 10. elongated slot, 11. motors, 12, bolt.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Among Fig. 1, base plate 7 is located on the cutter platform of lathe, and base plate 7 is provided with elongated slot 10, and the electric baseboard 8 of motor 11 by the bottom is installed in the elongated slot 10 on the base plate 7.Motor output shaft is provided with driving wheel 9, and there is the wheel edge at the two ends of driving wheel 9, and cylindrical becomes sphere.Base plate 7 one sides are connected with the driven pulley device by gripping sleeve 3, and driven pulley 6 outsides of driven pulley device are provided with one deck rubber, and driving wheel 9 is connected with driven pulley 6 by the abrasive band.
The driven pulley device comprises gripping sleeve 3, sleeve 2, axle 5 and driven pulley 6, gripping sleeve 3 is connected with sleeve 2, by bearing fixing axle 5 is arranged in the sleeve 2, the front end of sleeve 2 is provided with to lead to and covers 4, the rear end is provided with stifle 1, the front end of axle 5 is fixed with driven pulley 6, and the cylindrical that contacts with rubber layer on the driven pulley 6 is provided with left-handed and right-handed thread.
During the utility model work, driven pulley 6 is pressed in gently on the surface of workpiece, running up by motor 11 drives driving wheel 9 rotations, and driving wheel 9 drives driven pulley 6 rotations by the abrasive band and carries out grinding.
Electric baseboard 8 of the present utility model can slide on the base plate 7 that elongated slot 10 is arranged, and adjusts by bolt 12 during use, keeps certain expanding force to guarantee to be used for the abrasive band of transmission; When between abrasive band and the workpiece certain pressure being arranged, the rubber on the driven pulley 6 produces certain deformation, is unlikely the surface of destroying workpiece, and plays the effect of grinding.Gripping sleeve 3 clamps for open type, to make things convenient for the dismounting maintenance of sleeve 2; There is certain wheel edge at the two ends of driving wheel 9, and cylindrical will be designed to sphere, to guarantee that the abrasive band does not skid off two wheels when running up; The diameter of driven pulley 6 can design according to the size of workpiece table top, changes during use, avoids the interference of sleeve 2, to guarantee can both to carry out grinding to various step surfaces; Choosing of abrasive band will be chosen thickness as required, so that workpiece is roughly ground, finish grinded; Cylindrical is designed to left-handed and right-handed thread before the driven pulley kiss-coating, does not come off when the wheel high speed rotating to guarantee rubber.
This equipment in use with the upper end clamping of base plate 7 on the cutter platform of vertical lathe, motor power is connected and can be used, the rotating speed of workpiece can be chosen according to the diameter of work size, to guarantee certain linear velocity.
