Abstract
The utility model discloses a grinder for a valve seat of a compressor. The grinder is characterized by comprising a bracket, a machine body installed at the top of the bracket, and a motor installed on a cross plate of the bracket, wherein the machine body comprises a tray, a gear ring fixed on the tray, as well as a grinding disc, a plurality of intermediate gears and a sun gear arranged in the gear ring; the grinding disc is detachably installed on the tray, and abrasive sand is covered on the surface of the grinding disc; a crankshaft of the motor is in transmission connection with a transmission shaft which upwards penetrates through centers of the centers of the tray and the grinding disc; the plurality of intermediate gears are uniformly distributed at the periphery of the sun gear; the gear ring is provided with an inner gear, and the intermediate gears are meshed with the sun gear and the gear ring. According to the grinder for the valve seat of the compressor, workpieces such as the valve seat of the compressor and the like which are damaged due to abrasion are ground to be repaired for utilization, so that a large quantity of maintenance cost of the compressor is saved; and the grinder has a simple structure, is reliable in running and low in noise, and consumes less power.
Description
Technical field
The utility model relates to a kind of equipment that keeps in repair workpiece such as compressor valve valve seat that is used to grind, and specifically, relates to a kind of compressor valve valve seat grinder.
Background technology
In enterprises such as chemical fertilizer factory, oil plant, chemical plant, compressor is a kind of common equipment of indispensability.Compressor in inlet and outlet work running since its inlet and outlet valve block incessantly reciprocation cycle open, close work, valve seat contact seal surface wear is serious; The valve base sealing contact-making surface is uneven, thereby causes compressor operating when operation return-air, gas leakage, and cylinder pressure at different levels are uneven; Simultaneously, compressor casing, valve heating, temperature rises; Cause compressor to break down, will increase the enterprise production cost like this, influence the enterprise production benefit.
Summary of the invention
The technical problem that the utility model will solve is to overcome above-mentioned defective; Provide a kind of and make the bad workpiece smooth grinding reparations such as compressor valve valve seat of wearing and tearing utilize, save maintenance cost, and simple to operate, reliable, noise is low, the compressor valve valve seat grinder of energy saving.
For addressing the above problem, the technical scheme that the utility model adopted is:
A kind of compressor valve valve seat grinder is characterized in that: comprise support, be installed in the body of a top of the trellis and be installed in the motor on the support transverse slat; Said body comprises pallet, is fixed on the gear ring on the pallet, and is located at abrasive disk, idler gear and central gear in the gear ring; Abrasive disk is removably mounted on the pallet, and its surface is covered with abrasive sand; The arbor of the motor power transmission shaft that is in transmission connection, power transmission shaft is upward through the center of pallet, abrasive disk; Central gear is fixedly mounted on the top of power transmission shaft; Idler gear is provided with several, is evenly distributed on around the central gear; Gear ring is provided with internal tooth, and idler gear and central gear, gear ring often mesh.
Say that further the arbor of said motor is through the reductor power transmission shaft that is in transmission connection.
Owing to adopted technique scheme, the utility model can make the bad workpiece smooth grinding reparation utilizations such as compressor valve valve seat of wearing and tearing, thereby saved a large amount of compressor maintenance costs; And the utility model is simple to operate, reliable, noise is low, energy saving.
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described further.
Description of drawings
Fig. 1 is the structural representation of a kind of embodiment of the utility model;
Fig. 2 is the vertical view of a kind of embodiment of the utility model.
Among the figure: the 1-support; 2-support transverse slat; The 3-motor; The 4-power transmission shaft; The 5-chassis; The 6-gear ring; The 7-abrasive disk; The 8-abrasive sand; The 9-idler gear; The 10-central gear; The 11-reductor.
The specific embodiment
Embodiment:
A kind of compressor valve valve seat grinder shown in Fig. 1-2, comprises support 1, is installed in the body at support 1 top and is installed in the motor 3 on the support transverse slat 2.Said body comprises pallet 5, is fixed on the gear ring 6 on the pallet 5, and is located at abrasive disk 7, idler gear 9 and central gear 10 in the gear ring 6.Abrasive disk 7 adopts wearable ductile iron to make, and anti-wear performance is strong, and in the valve seat process of lapping, abrasive disk 7 ability self-grind equatings remain smooth.Abrasive disk 7 is removably mounted on the pallet 5, and abrasive disk 7 wearing and tearing backs are changed easily, and are easy to maintenance.The surface of abrasive disk 7 is covered with abrasive sand 8.Abrasive sand 8 overlays on the abrasive disk 7 after being mixed into the mud shape with kerosene or diesel oil.The arbor of motor 3 is through reductor 11 power transmission shaft 4 that is in transmission connection, and power transmission shaft 4 is upward through the center of pallet 5, abrasive disk 7.Central gear 10 is fixedly mounted on the top of power transmission shaft 4.Idler gear 9 is provided with several, is evenly distributed on around the central gear 10.Gear ring 6 is provided with internal tooth, and idler gear 9 often meshes with central gear 10, gear ring 6.
When compressor valve valve seat is ground maintenance, place it in earlier in the idler gear 9, can place 1-4 compressor valve valve seat in each idler gear.
Process of lapping is divided into two stages: rough lapping and smooth grinding.
Rough lapping: with 60～80 order abrasive sands and kerosene or diesel oil be mixed into the mud shape overlay on abrasive disk 7 table and; The valve valve seat that will grind then is positioned in the idler gear 9; Open motor, power transmission shaft 4 drives central gear 10, and central gear 10 drives idler gear 9 and rotates; Can accomplish rough lapping in 4～5 hours, and treat to carry out smooth grinding again after valve valve seat abradant surface minimum point polishes compressor valve valve seat.
Smooth grinding: after the rough lapping of valve valve seat, with 120～180 order abrasive sands it is carried out smooth grinding, smooth grinding generally needs 1 hour.
