Description
Technical Field
The utility model relates to a machine-building technical field, especially emery wheel turbulent flow interference ware.
Background
At present, dust generated during the operation of a grinding and polishing machine is usually collected and filtered by a dust collection device, a suction inlet of the dust collection device is communicated with a grinding and polishing bin on the polishing machine, and the dust is sucked into the device by enabling the suction inlet to form negative pressure; however, the grinding wheel for driving the polishing abrasive belt to roll can drive peripheral air to move when rotating, so that air turbulence is formed, the air turbulence can destroy the balance of air flow in the polishing bin, and dust in the polishing bin is leaked out from a gap or an opening.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a simple structure can prevent that the dust from raising outward and guarantee the emery wheel turbulent flow interference ware of the collection of dust to the not enough of above-mentioned prior art.
The utility model discloses a realize above-mentioned purpose like this:
the grinding wheel turbulence interference device comprises a plurality of air collecting guide vanes which are fixed between the baffle plates at two sides and are close to the surface of the grinding wheel and face to an air inlet of the air suction flow distribution box.
The upper ends of the two side baffles are fixedly provided with connecting plates, the connecting plates are movably connected with one ends of the adjusting screws, the other ends of the adjusting screws penetrate through nuts matched with the adjusting screws to be connected with hand wheels, and the nuts are fixed on the mounting plate.
The two side baffles are positioned in the limiting cover, the air outlet of the limiting cover faces the air inlet of the air suction flow distribution box, and the limiting cover is fixed on the inner wall of the mounting plate.
Wherein, the middle lower part of the air-collecting guide vane is provided with a gap for being sleeved in the grinding wheel, and each part of the air-collecting guide vane is respectively positioned on the two sides and the upper surface of the grinding wheel.
The upper section of the air collecting guide vane faces to an air inlet of the air suction flow dividing box and is bent.
The utility model has the advantages that: a plurality of air collecting guide vanes are arranged between the baffle plates at the two sides, and the air collecting guide vanes are close to the surface of the grinding wheel and face the air inlet of the air suction flow dividing box. Therefore, the air driven by the grinding wheel and used for clamping the dust can flow to the air inlet of the air suction flow distribution box under the guide of the air collection guide vane and is sucked away by the air suction flow distribution box, the dust is prevented from being raised outwards, and the collection of the dust is ensured. The utility model discloses simple structure to can effectively block the dust and outwards give off.
Drawings
The invention will be further described with reference to the following figures and examples:
fig. 1 is a schematic side view of the present invention;
fig. 2 is a schematic view of the structure of the present invention.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the following description, in conjunction with the examples and the accompanying drawings, is intended to illustrate the present invention in further detail, and the exemplary embodiments and the description thereof are only used for resolving the present invention, and are not intended to limit the present invention.
Referring to fig. 1 and 2, the air collecting and guiding device comprises a plurality of air collecting and guiding blades 5, wherein the air collecting and guiding blades 5 are fixed between two side baffles 10 and are close to the surface of the grinding wheel 4 and face an air inlet 15 of the air suction diversion box 3. Therefore, the air which is driven by the grinding wheel 4 and used for clamping the dust can flow to the air inlet of the air suction flow distribution box under the guide of the air collection guide vane and then is sucked away by the air suction flow distribution box, so that the dust is prevented from being raised outwards and the collection of the dust is ensured.
The upper ends of the two side baffles 10 are fixedly provided with connecting plates 1, the connecting plates 1 are movably connected with one ends of adjusting screws 12, the other ends of the adjusting screws 12 penetrate through nuts 14 matched with the adjusting screws to be connected with hand wheels 16, and the nuts 14 are fixed on the mounting plate 11. The hand wheel 16 is rotated, the connecting plate 1 connected with the adjusting screw 12, the two side baffles 10 and the air collecting guide vane 5 move up and down, so that the installation requirements of grinding wheels with different diameters are met. When a grinding wheel with a larger diameter needs to be installed, the hand wheel 16 is rotated to enable the connecting plate 1, the two side baffles 10 and the wind collecting and guiding sheet 5 to move upwards, otherwise, the opposite is true. The connection plate 1 is movably connected with one end of the adjusting screw 12 in a manner that one end of the adjusting screw 12 is fixed on an inner ring of the bearing, and an outer ring of the bearing is fixed on the connection plate 1 or a bearing seat thereof.
In order to further ensure that the air containing dust flows to the air inlet of the air suction shunting box, the two side baffles 10 are positioned in the limiting cover 18, the air outlet 13 of the limiting cover 18 also faces to the air inlet 15 of the air suction shunting box 3, and the limiting cover 18 is fixed on the inner wall of the mounting plate 11. Thereby further preventing dust from rising to the outside of the polishing and grinding machine.
Besides, the middle lower part of the air-collecting guide vane 5 is provided with a gap 20 which is sleeved in the grinding wheel 4, and each part of the air-collecting guide vane 5 is respectively positioned on the two sides and the upper surface of the grinding wheel 4. Therefore, the air flow of the dust-collecting air clamped at the periphery of the grinding wheel can be more effectively guided to the air inlet of the air suction flow distribution box, and the dust is further prevented from being raised outwards to the polishing and grinding machine.
In addition, the upper section 7 of the air collecting guide vane 5 is bent towards the air inlet 15 of the air suction shunting box 3, and the structure can effectively guide the air which clamps dust to flow to the air inlet of the air suction shunting box, so that the dust is prevented from being raised outwards to the polishing and grinding machine in a maximum angle.
It is to be understood that the foregoing examples merely represent preferred embodiments of the present invention, and that the description thereof is more specific and detailed, but not intended to limit the scope of the invention; it should be noted that, for those skilled in the art, the above technical features can be freely combined, and several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention; therefore, all changes and modifications that come within the meaning and range of equivalency of the claims are to be embraced within their scope.
