The specific embodiment
See also Fig. 1 to shown in Figure 4, the utility model first preferred embodiment comprises:
One polishing machine body 10, it is the housing of bottom opening, and be provided with an intake valve 11 and a dust leg 12 in upper and lower the stretching respectively of a side, communicate with the downside of polishing machine 10 body interior and can be in order to bleeding control of dust by dust leg 12, polishing machine body 10 tops be pivoted with one can press by and the plate machine 13 of control intake valve 11 air inlets.
One power motor 20, it is the upside that is installed in the polishing machine body 10, and connect pneumatic supplies and power resources are provided by intake valve 11, in addition, power motor 20 also can be the pattern of electro-motor, the utility model does not limit at this, power motor 20 at the shaft core position of bottom to having an eccentric shaft 21, these eccentric shaft 21 bottoms are a balance-weight crankshaft portion 211, balance-weight crankshaft portion 211 is that an end outwards protrudes out and horizontal microscler block, but ties the sanding disc axle center 22 of a rotation at balance-weight crankshaft portion 211 bottoms off-centre pivot.
One dust cover 30A, it is the ring bodies that outer peripheral edges form an annular eaves 31A of portion downwards, and be incorporated into the periphery of polishing machine body 10 bottoms with inner peripheral, dust cover 30A uniformly-spaced is equipped with 12 column casing 32A in the bottom, be provided with vertical screw 321A in each column casing 32A, and each screw 321A has screwed togather a brake unit 40A, each unit 40A that brakes is provided with a cylinder 41A who is screwed together in each screw 321A, cylinder 41A is a double-screw bolt, and forms an enlarged head 411A in cylinder 41A bottom, as shown in Figure 3A.Enlarged head 411A is the hexagon block in this preferred embodiment, stretches downwards in enlarged head 411A bottom to be provided with a friction piece 42A, and this friction piece 42A is a brush body in this preferred embodiment.In addition, the quantity of the quantity of column casing 32A and brake unit 40A can optionally increase and decrease, and also can not do mutual equally spaced setting, and also can not be provided with column casing 32A and cylinder 41A directly is incorporated into dust cover 30A bottom, and this preferred embodiment does not limit at this.
One sanding disc 50, be greater than the disc of dust cover 30A and be located at place, dust cover 30A below, sanding disc 50 is vertically stretched up in the central authorities of end face and is provided with a screw rod 51, be fixed at the bottom in sanding disc axle center 22 with screw rod 51, and the periphery of sanding disc 50 end faces contacts with the friction piece 42A of each brake unit 40A and rubbed by it.
See also second preferred embodiment shown in Fig. 5, Fig. 6, it is that the dust cover 30A in first preferred embodiment is improved, be not provided with column casing 32A through improved this dust cover 30B, and in the downward annular eaves 31B of portion that forms of outer peripheral edges, and directly be equipped with several brakes unit 40B in the bottom of the ring eaves 31B of portion, each unit 40B that brakes stretches the cylindrical projection 41B that establishes downwards, the periphery at each friction sanding disc 50 top, projection 41B bottom.
When using the utility model, with first preferred embodiment is example, be to drive eccentric shaft 21 and sanding disc axle center 22 with power motor 20, and then drive sanding disc 50 swings and in order to burnishing, because the friction piece 42A contact sanding disc 50 of each brake unit 40A, therefore there is predetermined frictional force to be continuously applied on sanding disc 50.Yet because the driving force of power motor 20 is big, the frictional force of friction piece 42A is unlikely to influence sanding disc 50 operations again when polishing,
When power motor 20 stops, sanding disc 50 can run out of steam and rotation, but because each brake unit 40A puts on frictional force on the sanding disc 50, the brake effect that sanding disc 50 is reached comparatively fast stop, and can increase and decrease the quantity of brake unit 40A according to circumstances, to change the frictional force size of whole brake.
In addition, because brake unit 40A is screwed together in the column casing 32A with cylinder 41A, when using after a period of time brush body as friction piece 42A to shorten because of wearing and tearing, can be downward with the position of cylinder 41A rotation adjustment brake unit 40A, reach the effect that continues use and do not need often to change new brake unit 40A.
