Abstract
The utility model discloses an upper rubbing head for a grinding machine. The upper rubbing head comprises an upper rubbing plate, a spindle connected with the upper rubbing plate, and a motor for driving the spindle to rotate; an air cylinder is connected at the top of the spindle; a spindle sleeve is arranged outside the spindle; an outer shaft sleeve is mounted outside the spindle sleeve through a copper sleeve; and the spindle is connected with the upper rubbing plate and an output shaft of the air cylinder through universal bearings. According to the upper rubbing head provided by the utility model, the pressure of the air cylinder is transmitted to the spindle through two universal bearings, and the spindle flexibly swings and rotates, so that a force of the spindle is transmitted to the upper rubbing plate, and the upper rubbing plate flexibly swings. Therefore, the rotation problem of the conventional upper rubbing head for the grinding machine can be solved; the rigidity is enough; and a work piece clamp plate can be conveniently mounted and dismounted.
Description
Technical field
The utility model belongs to the cutting machines field, is specifically related to a kind of last rubbing head of grinder.
Background technology
Grinder is widely used in the carbide alloy deep processing, is commonly used to the parts that accurate to dimension and roughness are had relatively high expectations, and this type part work in-process often need could satisfy industrial matching requirements through grinding repeatedly.The last rubbing head of grinder in the prior art, the problem that exists in the use mainly are that the installation and removal of work piece holder dish are all not too convenient.
The utility model content
The purpose of the utility model provides a kind of good rigidly, and upper and lower dish is gone up rubbing head easily.
The utility model solves the technical scheme that its technical problem adopted: a kind of last rubbing head of grinder; Comprise the motor that polishing disk, the main shaft that is connected with last polishing disk and driving main shaft are rotated; The main shaft top is connected with cylinder; Main shaft is provided with collar bush outward, and collar bush is outer to be equipped with outer shaft through copper sheathing, and described main shaft is connected with the gentle cylinder output shaft of last polishing disk respectively through universal bearing.
Wherein, described main shaft is connected with collar bush through the main shaft bearing at two ends, and described bearing is provided with dust cap outward.
The beneficial effect of the utility model is: be delivered on the main shaft through the pressure of two universal bearings with cylinder; And make main shaft swing flexibly and rotate; The power of main shaft is delivered on the polishing disk and polishing disk is swung flexibly; Solved the rotation problem of rubbing head on the grinder in the past, rigidity is enough, and the work piece holder dish can upper and lower very easily dish.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further explain.
With reference to shown in Figure 1; The utility model discloses a kind of last rubbing head of grinder, comprise the motor 11 that the last polishing disk 1 that loads the workpiece clamping apparatus disk, the main shaft 5 that is connected with last polishing disk 1 and driving main shaft 5 are rotated, main shaft 5 is used for pressure and revolving force are delivered to down polishing disk; Main shaft 5 tops are connected with cylinder 12; Be used to promote main shaft 5 and give main shaft 5 pressurizations, main shaft 5 peripheral hardwares are useful on the collar bush 6 that carries main shaft 5, and collar bush 6 outer being equipped with through copper sheathing 8 are led up and down with outer shaft 7; Described main shaft 5 is connected with cylinder 12 output shafts with last polishing disk 1 respectively with 10 through two universal bearings 2; Wherein said main shaft 5 is connected with collar bush 6 with 9 through two main shaft bearings 3 at two ends, and described bearing is provided with dust cap 4 outward, prevents that foreign material such as dust, water from getting into bearing.
The utility model is delivered on the main shaft 5 through the pressure of universal bearing 10 with cylinder 12; And make main shaft 5 swing flexibly and rotate; Be delivered to the power of main shaft 5 on the polishing disk 1 and polishing disk 1 is swung flexibly through universal bearing 2, solved the rotation problem of rubbing head on the grinder in the past, rigidity is enough; And saved shelves and colluded mechanism, the work piece holder dish can upper and lower very easily dish.
The foregoing description is the principle and the effect thereof of illustrative the utility model only; And the embodiment of part utilization; For the person of ordinary skill of the art; Under the prerequisite that does not break away from the utility model creation design, can also make some distortion and improvement, these all belong to the protection domain of the utility model.
