A kind of Novel bevel gear driven type polishing grinding head
Technical field
The invention belongs to ceramic wall and floor bricks (stone material) deep-processing machine equipment technical field, be specifically related to a kind of Novel bevel gear driven type polishing grinding head.
Background technology
At present in China along with living standards of the people and raisings day by day aesthetic standards, to the quality of ceramic, and the roughness on surface is had higher requirement.Ceramic polished brick adapts to current demand becomes one of ceramic that is most widely used in the modern architecture fitting-out work.
Ceramic tile polisher is equipment important in the ceramic tile process, and bistrique most important parts on polishing machine sometimes.Existing Imitation Rock Porcelain Tiles (stone material) grinding head for polishing is of a great variety, and cam-type, inclined disc type, eccentric disc type etc. are arranged, and what wherein be most widely used is cam-type bistrique and inclined disc type bistrique.Along with the raising of large specification ceramic tile processing request and the requirement of energy-saving and emission-reduction, ceramic tile production is produced house bistrique is had higher requirement, and hope can be satisfied by increasing the technological means such as abrading block, expansion bistrique diameter the requirement of production and processing.But what the cam-type bistrique adopted is many waveforms cam, and the swing of an abrading block seat of every increase will be revised the shape of cam, brings difficulty for processing and design, thereby has restricted the development of cam-type bistrique.If increase the bistrique diameter, the swash plate of inclined disc type bistrique will increase, and cause the also corresponding increase of weight of bistrique, and then increase manufacturing cost.In addition, during the operation of cam-type bistrique and inclined disc type bistrique, vibrate greatlyr, the brickbat rate is higher.
Summary of the invention
The object of the invention is to provides a kind of Novel bevel gear driven type polishing grinding head for the deficiencies in the prior art part, and it can increase abrading block seat and bistrique diameter easily according to actual processing request.
For achieving the above object, the present invention adopts following technical scheme:
A kind of Novel bevel gear driven type polishing grinding head, comprise head holder, main shaft, transmission mechanism, swing mechanism and abrading block seat, described transmission mechanism comprises driving gear, travelling gear and driven gear, described main shaft drives head holder and driving gear rotates, and described swing mechanism comprises some swinging axles; Described transmission mechanism also comprises: drive bevel gear, empty set are on main shaft and concentric affixed with driven gear; Some driven wheels of differential wait angle to be arranged in head holder, and mesh with drive bevel gear respectively; Described swing mechanism also comprises: the swing pin that quantity is identical with driven wheel of differential, and an end of each swing pin is eccentric being connected on the end face that there is no the gear teeth of a driven wheel of differential respectively; The quantity of described swinging axle is identical with the swing pin, and an end of each swinging axle radially is provided with a U-lag; The other end of described each swing pin is inserted respectively in a U-lag.
Further, an end of described each swinging axle is provided with a disk, and described U-lag is arranged on disk.
Further, the quantity of described head holder is identical with swinging axle, and each head holder is connected with a swinging axle respectively.Because each head holder is directly driven by swinging axle, therefore need not adopt fork initiatively to drive the mode of driven fork, artificial adjusting play has thoroughly solved the vibration that oscillating grinding head produces because of the fork gap.
As preferably, the quantity of described driven wheel of differential is for being no less than three.
The present invention is by adopting said structure, and have following advantage: (1) has simplified driving mechanism; (2) simplified swing mechanism; (3) can increase abrading block seat quantity according to Production requirement; (4) reduced the vibration of polishing machine; (5) eliminated thoroughly that the cam-type bistrique needs the adjusting play and the inconvenience that brings; (6) extended the service life of bistrique; (7) reduced the ceramic tile wear rate; (8) operate steadily, reliability is high.

Now in conjunction with the accompanying drawings and embodiments the present invention is described in further detail.
The specific embodiment
To shown in Figure 6, Novel bevel gear driven type polishing grinding head of the present invention mainly is comprised of main shaft 1, head holder 2, bistrique lid 3, transmission mechanism, swing mechanism and six abrading block seats 6 as Fig. 1.
Main shaft 1 is multidiameter, is located in the middle part by head holder 2 and bistrique lid 3 bistriques that form, and rotates around the spindle by flange 11 drive head holders 2.Bistrique lid 3 is connected with lathe, not along with main shaft 1 rotates together.
Transmission mechanism mainly is comprised of driving gear 41, travelling gear 42, driven gear 43, drive bevel gear 44 and six driven wheels of differential 45.Driving gear 41 is set on main shaft 1 and with main shaft 1 by key 12 and rotates.Travelling gear 42 is fixed on bistrique lid 3 and with driving gear 41 and meshes.The coaxial empty set of driven gear 43 meshes on main shaft 1 and with travelling gear 42.Drive bevel gear 44 empty sets are fixed together by screw is concentric on main shaft 1 and with driven gear 43.Six driven wheel of differential 45 angles such as grade are arranged in head holder 2, and mesh with drive bevel gear 44 respectively.
Swing mechanism mainly is comprised of six swinging axles 51 and six swing pins 52.Every swinging axle 51 is connected with an abrading block seat 6 respectively.One end of every swinging axle 51 is provided with a disk 511, radially is provided with a U-lag 512 on disk 511.One end of every swing pin 52 is eccentric being connected on the end face that there is no the gear teeth of a driven wheel of differential 45 respectively, and its other end is inserted in the U-lag 512 of swinging axle 51 1 ends.
The course of work of the present invention is as follows:
Motor drives main shaft by belt pulley and rotates, thereby drives the head holder rotation, drives simultaneously the driving gear that is connected together by key and rotates, and driving gear drives travelling gear, and travelling gear drives again driven gear and drive bevel gear is rotated.Due to the engagement of driven wheel of differential and drive bevel gear, thus drive bevel gear horizontally rotate the vertical rotation that changes driven wheel of differential into.The driven wheel of differential rotating drive swings pin, thereby the motion that the swing pin is done in the U-lag of swinging axle as shown in Figure 6 swings swinging axle, and then band dynamic grinding block seat is made wobbling action around swinging axle.The grinding motion of bistrique is that abrading block swings around swinging axle the compound motion that these two kinds motions form around circumference rotation and the abrading block of main shaft, make abrading block and institute's linear contact in flat surface grinding, so grinding pressure is large; Swinging of abrading block, the abrasive particle of blunt are can be very fast squeezed broken and generate new processing corner angle in this swings, and the sand that has processed simultaneously also can be discharged and the gap of unlikely obstruction abrading block in the motion that swings together easily with the abrasive particle of blunt.
