Description
Technical Field
[0001] The utility model relates to the technical field of tooling, in particular to a precision thrust bearing thrust surface grinding tooling. Background Art
[0002] Thrust pad is a mechanical component used in rotating equipment, such as turbines. Specifically, the thrust pad is usually installed on the thrust bearing of the equipment and is in direct contact with the thrust plate of the rotating part (such as the rotor). When the rotating part is running, a certain axial thrust will be generated, which will be absorbed and dispersed by the thrust pad.
[0003] However, since the thrust pads are mostly composed of beveled edges and arc edges, it is difficult to effectively adapt to thrust pads of different sizes and fix multiple thrust pads at the same time when the grinding device is started for grinding after the thrust pads are fixed, which reduces the adaptability and grinding efficiency. Utility Model Content
[0004] The purpose of the utility model is to solve the problem in the prior art that thrust pads are mostly composed of beveled edges and arc edges, which makes it difficult to effectively adapt thrust pads of different sizes and fix multiple thrust pads at the same time when the grinding device is started for grinding after the thrust pad is fixed, thereby reducing the adaptability and grinding efficiency. A precision thrust pad thrust surface grinding tool is proposed.
[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0006] A precision thrust bearing thrust surface grinding tool, comprising a grinding device, for grinding the thrust bearing;
[0007] A placement rack, used for placing the thrust pad, the placement rack is located below the grinding device, and a plurality of placement grooves arranged in an annular shape are provided on the top of the placement rack;
[0008] A plurality of clamping plates, used for clamping the thrust washer, wherein the plurality of clamping plates are all located inside the placement frame;
[0009] A fixing piece is used to fix the clamping plate. The fixing piece is located below the placement rack. The fixing piece includes a fixing ring and a threaded ring located below the placement rack. The fixing ring is fixedly sleeved on the top of the outer wall of the threaded ring.
[0010] In a possible design, a concave surface is opened in the top center of the placement rack, a column is fixedly set on the bottom inner wall of the concave surface, a connecting ring is rotatably sleeved on the outer wall of the column, and one end of each of the plurality of clamps is fixedly set on the outer wall of the connecting ring.
[0011] In a possible design, the inner wall of the concave surface is provided with a plurality of inner through holes, and the plurality of inner through holes are respectively connected to the plurality of placement grooves; the outer wall of the placement rack is provided with a plurality of outer through holes, and the plurality of outer through holes are respectively connected to the plurality of placement grooves; and the plurality of splints extend to the outside of the placement rack through the plurality of inner through holes and the plurality of outer through holes.
[0012] In a possible design, a chassis is fixedly provided at the bottom of the placement rack, the threaded ring is threadedly sleeved on the outer wall of the chassis, and the fixed ring is sleeved on the outer wall of the placement rack.
[0013] In a possible design, the inner wall of the fixing ring is configured as an inclined surface, and the inclined surface matches one end of a clamping plate extending to the outside of the placement rack.
[0014] In a possible design, a plurality of fixing grooves are provided on the outer wall of the placement rack, and the fixing grooves are located below the outer through holes, and a threaded rod is provided on the outer wall of the fixing ring, and the threaded rod threads penetrate the fixing ring and cooperate with the plurality of fixing grooves.
[0015] In a possible design, the grinding device includes a grinder and a mirror plate fixedly arranged at an output end of the grinder.

Since one end of the clamping plate extends to the outside of the placement frame, and the inner wall of the fixing ring is an inclined surface (the upper circular hole inside the fixing ring is larger than the lower circular hole), when the fixing ring rotates upward, its inner wall will gradually squeeze one end of the clamping plate to make it tightly fixed, thereby fixing the thrust bearing, and in order to prevent the threaded ring from loosening, the threaded rod is rotated to move the threaded rod to the inside of the corresponding fixing groove to prevent loosening, and then the grinder can be moved downward by means of hydraulic rods and other equipment, so that the mirror plate at the output end of the grinder fits with the thrust surface of the thrust bearing, and then the grinder is started for grinding, so that multiple thrust bearings can be fixed at one time for grinding together, thereby increasing the effect.
[0017] In the utility model, the precision thrust bearing thrust surface grinding tool can place multiple thrust bearings at one time through the placement rack when grinding the thrust surface of the thrust bearing, and then carry out the grinding process together through the grinding device, thereby increasing the grinding efficiency by increasing the number of grindings at one time;
[0018] In the utility model, the precision thrust bearing thrust surface grinding tool can achieve the goal of placing multiple thrust bearings inside the placement frame through the fixing parts, first clamping the thrust bearings with the clamping plates, and then tightening and fixing the multiple clamping plates through the fixing parts, so as to fix the multiple thrust bearings at one time, thereby realizing the work of grinding the multiple thrust bearings at one time;
[0019] In the utility model, when in use, after placing a plurality of thrust pads in the placement groove, the clamping plate can be moved to clamp the thrust pads, and then the clamping plate can be fixed by rotating the fixing ring, thereby achieving the effect of placing and fixing a plurality of thrust pads at one time;
[0020] Afterwards, the grinding device can be moved to fit the mirror plate and the thrust surface of the thrust washer for grinding, thereby achieving the effect of grinding multiple thrust washers at one time, thereby increasing work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
