The specific embodiment
The utility model relates to a kind of unsteady grinding head device of ceramic flat surface process equipment, in order to realize that ceramic brick surface is carried out polishing, below in conjunction with accompanying drawing, feature of the present utility model is elaborated:
Fig. 1 is the structure cutaway view according to the unsteady grinding head device of the ceramic flat surface process equipment of a kind of specific embodiment of the present utility model.With reference to Fig. 1, the unsteady grinding head device 100 of ceramic flat surface process equipment of the present utility model comprises motor 14, motor 14 output shafts are downward, be inversion state, the housing 141 of motor 14 is fixed in the upper surface of rotary table 30, rotary table 30 the one side with partly throw the machine host (not shown) and be connected, make it to drive rotation by partly throwing machine host, also being provided with power supply machine 14 output shafts 142 on the rotary table 30 passes through, and supply a bearing block 13 to be installed on its interior hollow-out parts 301, bearing block 13 be fixed in the motor fixation side to a right side, bearing block does not have through hole 131 to pass through for motor output shaft 142 for 13 kinds.Motor output shaft is affixed with rotating shaft 12 in the bearing seat surface, the partly cut-away of the countershaft among Fig. 1 has shown such structure, rotating shaft 12 has flange 121, the both sides of flange 121 respectively are provided with a bearing 10 again, and the outside of the bearing of close below also is provided with bearing gland 21, and bearing gland 21 is connected with the end of bearing block, form a chamber 40, this chamber 40 is used for from axial restraint bearing 10, and and then with rotating shaft 12 axial restraints, simultaneously can make it rotate.
The free end 122 of rotating shaft 12 stretches out from cavity 40, and with inner ring 51 tight fits, the outer ring 52 of oscillating bearing 5 and the inner surface tight fit of a bistrique mounting disc 3 of an oscillating bearing 5.Shown in Fig. 4,5, bistrique mounting disc 3 has a cylindrical tube 31, and cylindrical shell 31 has hollow lumen to hold oscillating bearing 5, outer ring 52 tight fits of its inner surface and oscillating bearing 5.The root edge of cylindrical shell 31 type that stretches out is chimb 311, and this chimb is in order to fixing bistrique (not shown); The top of cylindrical shell has hole 32, for rotating shaft by this hole and the hollow lumen that stretches into cylindrical shell 31 with the inner ring tight fit of oscillating bearing 5.Preferably, can also be by the inner ring 51 of joint switch 5 further being fixed in the end of rotating shaft 12 from going up the screw 1, spring washer 2 and the packing ring 4 that cooperate mutually.Preferably, can also fix a seal cover 24 by circlip 25 at the openend of the bottom of bistrique mounting disc.
In the present embodiment, this oscillating bearing 5 can be a self-lubricating plain radial bearing.
Yet the amplitude of fluctuation of the bistrique of above-mentioned grinding head device is also uncontrolled, therefore, can further increase a position-limit mechanism.
Position-limit mechanism can be realized in the following manner, and a locking nut 23 also is set above bistrique mounting disc 3, and this locking nut can be connected with rotating shaft by the form of screw thread, and its structure is shown in Fig. 6,7.Symmetry is provided with the pit 231 that holds the first sphere pin 81 on the locking nut 23, in the present embodiment, such pit 231 symmetries be provided with two, yet predictably, also can more pit be set, to hold the more first sphere pin in centrosymmetric mode.
At two pits 33 that are provided with of the top of bistrique mounting disc 3 correspondence, these two pits are used to hold the second sphere pin sphere pin 82 equally.Equally, can predict, the pit identical with the pit quantity of locking nut can be set more.
In the utility model, be example with the first sphere pin 81, as shown in Figure 3, the sphere pin refers to a kind ofly have cylindrical outer shape 811, and has the parts of sphere pit 812, these parts use in pairs, can be used for realizing that angle, position, spacing between parts regulate.
As shown in Figure 1, 2, the first sphere pin 81, the second sphere pin 82 are arranged at the pit 231 of locking nut respectively, and in the pit 33 of bistrique mounting disc, and keep the sphere pit of sphere pin to be oppositely arranged.In the first sphere pin that is oppositely arranged, the second sphere pin, be provided with steel ball 7.Being provided with of steel ball 7 need have such relation with sphere pin 8, guarantee that promptly steel ball 7 its outer surfaces fully contact with the sphere pit of first, second sphere pin that is oppositely arranged, and after guaranteeing steel ball 7 and first, second sphere pin cooperating, 81,82 of first, second sphere pins that are oppositely arranged leave the gap.Thereby, locking nut 23 and 3 gaps of also leaving same widths of bistrique mounting disc.
Preferably, be with flexible waterproof jacket 6 in the outside of locking nut 23 and bistrique mounting disc 3, as the rubber waterproof cover, this waterproof jacket 6 needs long enough, to shelter from the gap of 3 of locking nut 23 and bistrique mounting discs fully.
Often can not accurately estimate in advance because rotating shaft 12 middle parts are used to install the length of the screw thread of locking nut, therefore, what locking nut sometimes can not be firm is fixed in the rotating shaft, thereby can cause the location of locking nut inaccurate.Prevent that locking nut from taking place loosening and cause spacing inaccurate, can be above locking nut the top be provided with nut 9 with locking nut, like this, can guarantee that for the nut and the locking nut that are provided with locking nut can not become flexible, thereby the spacing accuracy that guarantees, in addition, by adjusting this round nut, can also adjust the gap that forms between the first sphere pin and the second sphere pin facing surfaces.
When the unsteady grinding head device of ceramic flat surface process equipment of the present utility model to ceramic product, when carrying out polishing operation as ceramic tile etc., as run into the surface of wavy fluctuating, oscillating bearing 5, the first sphere pin 81, the second sphere pin 82, steel ball 7 can be had an effect, oscillating bearing has guaranteed that rotating shaft keeps under the situation of plumbness, and bistrique mounting disc 3 can drive bistrique and freely tilt under the effect of oscillating bearing; Simultaneously, because the setting of sphere pin and steel ball has guaranteed that the angle that tilts can not surpass the spacing of first, second sphere pin that is oppositely arranged.
Being the utility model preferred embodiment only in sum, is not to be used for limiting practical range of the present utility model.Be that all equivalences of doing according to the content of the utility model claim change and modification, all should belong to technology category of the present utility model.
