The utility model discloses simple structure, reasonable in design, labour saving and time saving, the grinding speed is fast, and grinding effect is good, can adjust the grinding that the length of drive lever is used for various specification valves wantonly, and it is convenient to maintain and maintain, and vulnerable part low in cost changes swiftly, and easy operation can be suitable for the needs of various adverse circumstances, the utility model discloses a pneumatic motor and drive lever lug connection have reduced the influence of indirect drive to the revolution.
Description
Technical field
The utility model relates to a kind of lapping device, definite a kind of air sander lapping machine of saying so.
Background technique
Valve plays important effect in electric power, petrochemical industry, metallurgical industry, owing to leaking, valve sealing face causes that pollution, the loss that leakage accident caused are comparatively serious, directly influence economic benefit, sealing face damage is the main cause that causes valve to reveal, the extruding of mobile wearing and tearing of medium (water, vapour, wet goods) and corrosion impurity waits until that reason can form damages such as hollow, cut, spot, cause valve leak, must could eliminate through grinding, thus the leakproofness of assurance valve.At present, it is a lot of to grind the employed lapping machine kind of valve, imitated mostly external (European advanced technologies such as West Germany, Sweden) mainly are based on electronic, pneumatic is the kind of drive of assisting, and grinding consumptive material material, be divided into two kinds of materials of self-adhesion emery cloth and diamond grinding head, and research a large-scale valve (more than the Dg200) especially groove mark darker to surpass 0.33mm valve port material harder, use emery cloth to be difficult to eliminate.Can cause motor overheating or damage element because of long-time running makes mechanical driving part metal fatigue occur owing to influenced by the duration, repair time is long, changes element and costs an arm and a leg, and is not suitable for quick repairing needs in the engineering.
Summary of the invention
The purpose of this utility model is to overcome the deficiency that exists in the above-mentioned technology, provides a kind of simple in structure, reasonable in design, and grinding rate is fast, effective air sander lapping machine.
In order to achieve the above object, the technical solution adopted in the utility model is: the center portion is equipped with drive link and is fixed on the housing by end mounted bearing in housing, position, drive link upper end is equipped with the output shaft that position, upper end in coupling shaft and the housing is fixed with air motor and links to each other, the drive link lower end part is equipped with driving bevel gear and is connected with the universal joint that driven bevel pinion is meshing with each other with install in the wheel disc center portion of outside setting, is inlaid with grinding wheel in the groove of wheel disc setting.
The utility model has the advantages that:
1, simple in structure, reasonable in design, time saving and energy saving, grinding rate is fast, and grinding effect is good, and the length that can regulate drive link arbitrarily is used for all size grinding-in of valve;
2, maintenance is convenient, and easily damaged parts is cheap, changes quick;
3, simple to operate, can be suitable for the needs of various rugged environment;
4, the utility model adopts air motor directly to be connected with drive link, has reduced the influence of indirect drive to revolution;
Description of drawings
Fig. 1 is the utility model structural representation;
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
As shown in Figure 1, the utility model is that the center portion is equipped with drive link 2 and is fixed on the housing 1 by end mounted bearing 3 in housing 1, position, drive link 2 upper end is equipped with coupling shaft 4 and links to each other with the output shaft 12 that position, housing 1 interior upper end is fixed with air motor 5, drive link 2 lower end parts are equipped with driving bevel gear 6 and are connected with the universal joint 9 that driven bevel pinion 7 is meshing with each other with install in wheel disc 8 center portions of housing 1 outer installment, are inlaid with grinding wheel 10 in the groove that wheel disc 8 is provided with.
Described wheel disc 8 is provided with fixed emery wheel sheet 10, gland 11.
Working principle:
The compressed air inlet of the utility model by placing on the housing, air directly is blown into the air motor that the position, upper end is provided with in the housing, make the air motor high speed rotating, this motor idling lotus is 6000 rev/mins, also can reach 1000 rev/mins during on-load, drive coupling shaft and rotate the drive drive link rotation concentric with coupling shaft, make the drive link lower end that driving bevel gear and the driven bevel pinion wheel disc that the transmission device that constitutes links to each other with universal joint that is meshed is set and rotate, owing to the valve port that is inlaid with grinding wheel and wheel disc synchronous high-speed spin finishing valve on the wheel disc.
Universal joint adaptation described in the utility model is freely rotated in 30 ° of degree angles, and flexibility and reliability is owing to adopt the umbrella gear driving mechanism to reduce noise.Improved stability, and it is extremely wear-resistant, to the above gate valve of super large valve (Dg400), can change the large-scale abrasive disk of aluminium sheet processing, utilize the self-adhesion emery cloth to grind by the way that reduces blast control revolution, the utility model can be used for the high pressure of the lower valve latus rectum Dg150-Dg400 of domestic and international 600MW unit, the sealing surface of low pressure gate valve grinds, and its ultimate elongation reaches 1.2m.
