Abstract

Disclosed is a planet surface grinding machine, which is composed of a motor, a machine frame, a work table, a grinding wheel, a gear box, a central shaft, etc. The utility model adopts a mechanism of a differential planet gear for transmission; two internal gears, two central gears and a tie rod are arranged on a central shaft in the gear box; one of the internal gears is fixed and the other internal gear rotates along the central shaft; an upper central gear is connected with the two internal gears through a planet gear; a lower central gear is connected with a grinding wheel spindle and the grinding wheel through the planet gear; the grinding wheel is driven to rotate along the grinding wheel spindle in high speed by the central shaft; besides, the grinding wheel is driven to rotate in slow speed along the central shaft. The utility model has the advantages of compact structure and small size; because work pieces do not do any movement when grinded, the energy consumption of the whole machine can be lowered.

Description

The planet surface grinding machine

The utility model relates to grinding machine, especially a kind of planet surface grinding machine.

Existing vertical grinder is that emery wheel rotates at a high speed, utilize the abrasive wheel end face grinding work piece, by a cover reducing gear workpiece is rotated around fixed axis simultaneously, reach the rapid stock-removal and the technological requirement of feeding at a slow speed, emery wheel fixed-site just, workpiece motion s, the grinding machine volume requirement of this form is bigger, and energy consumption is corresponding also big.

The purpose of this utility model just provides a kind of compact conformation, volume is little, energy consumption is low planet surface grinding machine, and it is to rotate at a high speed by emery wheel, and emery wheel reaches the rapid stock-removal and the technological requirement of feeding at a slow speed around the central shaft low speed rotation simultaneously.

The purpose of this utility model is realized by following technical scheme:

The planet surface grinding machine is by motor, frame, work stage, emery wheel, grinding wheel spindle, gear-box, formations such as central shaft, adopt the differential planet gear mechanism driving, central shaft is provided with two internal gears in the gear-box, two central gears and tie-rod, wherein an internal gear is fixed, another internal gear can move around central shaft, the fixing interlock of two central gears and central shaft, last central gear is by planetary gear and fixed annulus, movable internal gear links to each other, following central gear passes through planetary gear, grinding wheel spindle links to each other with emery wheel, central shaft had both driven grinding wheel spindle and emery wheel self fast rotational, and grinding wheel spindle and emery wheel are rotated at a slow speed around central shaft.

Planet surface grinding machine of the present utility model is owing to adopt the differential planet gear mechanism driving, so have compact conformation, little, the advantage of low energy consumption of volume, manufacturing cost is corresponding also low, because workpiece is not done any motion during grinding, as long as adopt suitable workbench, can carry out partly processing to large-scale workpiece or large-scale non-disconnectable part, be specially adapted to the manufacturing processing and the repairing of mould.

Below in conjunction with accompanying drawing the utility model is elaborated.

Fig. 1 is the utility model structural representation;

Fig. 2 is the utility model gear drive schematic diagram.

The planet surface grinding machine is by motor 1, frame 2, work stage 3, emery wheel 4, grinding wheel spindle 5, gear-box 6, central shaft 7 formations such as grade, adopt the differential planet gear mechanism driving, central shaft 7 is provided with internal gear 8 in the gear-box 6, internal gear 9, following central gear 10, last central gear 16 and tie-rod 14, internal gear 8 is fixed on the gear-box 6, internal gear 9 can be around central shaft 7 motions,

central gear

10,16 with the fixing interlock of central shaft 7, last central gear 16 links to each other with internal gear 8 by planetary gear 15, planet pin 13 links to each other with tie-rod 14, the one end is a planetary gear 15, the other end is a planetary gear 12, planetary gear 12 is meshed with internal gear 9, following central gear 10 and planetary gear 11 engagements, planetary gear 11 is located at an end of grinding wheel spindle 5, the other end of grinding wheel spindle 5 is an emery wheel 4, and grinding wheel spindle 5 is located on the internal gear 9, moves around central shaft 7 with internal gear 9.

Planet surface grinding machine operation principle of the present utility model:

Motor 1 drives central shaft 7 motions by belt, belt pulley, central shaft 7 is by central gear 10, planetary gear 11 make grinding wheel spindle 5 and emery wheel 4 rotation at a high speed down, central shaft 7 makes internal gear 9 rotate at a slow speed around central shaft 7 by last central gear 16 and planetary gear 15, planetary gear 12, grinding wheel spindle 5 and emery wheel 4 rotate at a slow speed around central shaft 7 again when self rotating at a high speed like this.
