Description
Technical field
The utility model belongs to field of mechanical technique, particularly a kind of polishing machine.
Background technology
Polishing machine has a wide range of applications in industries such as five metals, hot-water heatings.In the polishing machine use, need often to change polishing wheel.Polishing wheel is socketed on the turning cylinder of polishing machine.Because polishing wheel can not rotate with respect to turning cylinder in polishing process, so polishing wheel and turning cylinder are fixed together.If unload polishing wheel, just must make the turning cylinder difference, could the switching polishing wheel.
When polishing machine used, polishing wheel was along with the turning cylinder high speed rotating.Usually, between polishing wheel and the turning cylinder connect very tight.Therefore, when the dismounting polishing wheel, need make turning cylinder keep motionless as far as possible, firmly rotate polishing wheel then.
For this reason, the method that turning cylinder is not rotated is tightly to clamp turning cylinder with spanner or pipe vice.This method is required great effort very much, and damages turning cylinder easily.Simultaneously, when operation, need two people to finish.The method for dismounting of existing this polishing wheel makes the operation of polishing machine very loaded down with trivial details, has directly influenced the operating efficiency and the service life of polishing machine.
Summary of the invention
The purpose of this utility model is at the existing above-mentioned weak point of existing polishing machine, a kind of stop device of polishing machine turning cylinder is provided, make polishing machine easy to operate when changing polishing wheel by this device, improve the operating efficiency of polishing machine and prolong service life of polishing machine.
The purpose of this utility model can realize by following technical proposal: the stop device of this polishing machine turning cylinder is arranged at the bearing place of polishing machine turning cylinder, it is characterized in that, on turning cylinder, be with a stopping wheel, stopping wheel is in the sidepiece of bearing and is connected with turning cylinder, be provided with a positioning seat in the outside of stopping wheel, positioning seat is fixed on the bearing cap, a latch is arranged in positioning seat, latch passes positioning seat, its the inner can contact with the cylindrical of stopping wheel, the recess that has at least a front end that makes latch to embed on the cylindrical of stopping wheel is provided with a flexible control device of control latch between latch and positioning seat.
In the stop device of this polishing machine turning cylinder, stopping wheel is different with respect to turning cylinder, and latch can stretch.When latch inwardly stretches out, when making its front end embed the recess of stopping wheel cylindrical, latch just blocks stopping wheel, and stopping wheel can't be rotated, and turning cylinder can't have been rotated.At this moment, the operation of loading and unloading polishing wheel is just very convenient on turning cylinder.Behind the polishing wheel completed loading, outwards spur latch, make in the latch retraction positioning seat, stopping wheel just can be along with turning cylinder has freely rotated.Under this state, polishing machine can carry out normal polishing operation.
In the stop device of above-mentioned polishing machine turning cylinder, described stopping wheel can be a gear, and its recess is exactly the tooth paddy of cylindrical teeth, at the front end of latch the shape that matches with the tooth paddy of teeth is arranged.As long as the front end of latch embeds in the tooth paddy of stopping wheel cylindrical, can make the stopping wheel locking, also just can not rotate.
In the stop device of above-mentioned polishing machine turning cylinder, described stopping wheel also can be provided with several recess at its cylindrical.As long as latch inserts in one of them recess, stopping wheel can't have been rotated.
In the stop device of above-mentioned polishing machine turning cylinder, described control device comprises a spring, spring housing is connected on the latch, the two ends of spring act on respectively on latch and the positioning seat, on latch, also be provided with a blend stop, the guide groove that passes through for blend stop and the retaining edge at guide groove notch place are arranged on positioning seat.
In this control device, when blend stop was in the guide groove, under the effect of spring, latch inwardly stretched out, and its inner can embed in the recess of stopping wheel cylindrical, and stopping wheel is in the lock state.When outwards pulling out latch, its blend stop is come out and the pivot stop pin from guide groove, blend stop will be by the retaining of guide groove notch along blocking.At this moment, latch is in the retraction state, and stopping wheel can rotate along with turning cylinder, and polishing machine also just is in normal duty.
Compared with prior art, on polishing machine, set up the stop device that a utility model provides, just can control turning cylinder, make and change the easy to operate of polishing wheel, the operating efficiency and the service life of effectively having improved polishing machine.In use, as long as make latch flexible, operate very simple.Stop device can be arranged on various types of polishing machines, has higher utility.

Fig. 2 is the partial enlarged drawing at the stop device of this polishing machine turning cylinder latch place when being in the lock state.
Fig. 3 is the partial enlarged drawing at the stop device of this polishing machine turning cylinder latch place when being in unlock state.
Among the figure, 1, turning cylinder; 2, stopping wheel; 21, recess; 3, positioning seat; 31, guide groove; 32, retaining edge; 4, bearing; 5, motor; 6, latch; 61, blend stop; 7, bearing cap; 8, spring.
The specific embodiment
As shown in Figure 1, the turning cylinder 1 and the motor 5 of polishing machine link, and drive turning cylinder 1 by motor 5 and rotate together.Turning cylinder 1 passes bearing 4, supports by bearing 4.Stop device of the present utility model just is arranged at bearing 4 places.
Stop device comprises parts such as stopping wheel 2, positioning seat 3, latch 6 and spring 8.Stopping wheel 2 is in bearing 4 sidepieces, is fixed together with turning cylinder 1.Stopping wheel 2 rotates along with the rotation of turning cylinder 1.In the present embodiment, stopping wheel 2 is gears, and its cylindrical has teeth.The tooth paddy of teeth is promptly as the recess 21 of this stopping wheel.
Positioning seat 3 is in the outside of stopping wheel 2, is fixed on the bearing cap 7.Obviously, in the polishing machine use, positioning seat 3 is the same with bearing cap 7, is actionless.
As depicted in figs. 1 and 2, latch 6 passes positioning seat 3, spring 8 of socket on the latch 6.The two ends of spring 8 act on respectively on latch 6 and the positioning seat 3.Under the effect of spring 8, latch 6 can inwardly stretch out.The front end of latch 6 has the shape that matches with stopping wheel 2 recesses 21.
As shown in Figure 2, on latch 6, fixing blend stop 61.The guide groove 31 that passes through for blend stop 61 is arranged on the positioning seat 3.In the time of in blend stop 61 is in guide groove 31, under the effect of spring 8, the front end of latch 6 will embed the recess 21 of stopping wheel 2 cylindricals, promptly in the tooth paddy of teeth.At this moment, the turning cylinder 1 of polishing machine just is in the lock state.Under this state, the operation that the workman can carry out demolition and replacement to polishing wheel easily.
As shown in Figure 3, after the workman finishes operation to polishing wheel, can outwards spur latch 6, make the front end of latch 6 break away from the recess 21 of stopping wheel 2.Simultaneously, make blend stop 61 slide and skid off guide groove 31 along guide groove 31.After blend stop 61 skidded off guide groove 31, as long as rotate an angle, the retaining that makes blend stop 61 and guide groove 31 notches contacted along 32, just can prevent that latch 6 from inwardly stretching out.At this moment, turning cylinder 1 is in unlock state, and polishing machine can carry out normal polishing operation.
