The hydraulic principle diagram rotates the correction head feed knob and opens the trimmer advance and retreat cylinder, and performs 15° rough correction on the grinding wheel. The sample is tested by rough grinding the grinding wheel and the sample is measured. If the sample meets the requirements of the drawing, the part can be ground accordingly; if the sample does not meet the requirements of the drawing, then the adjusting rod is rotated, so that the movable bottom plate of the dresser is adjusted clockwise or counterclockwise by the positioning pin on the fixed bottom plate. A dial gauge fixed to the movable floor reads the amount of radial adjustment. (The geometric relationship between the dial gauge reading and the adjustment angle is as shown in the figure). Specifically, the detachable ropeway cabin (carriage of the passenger car) is clamped by the detachable gripping device, and the wire rope drives the hoisting car to realize high-speed movement. When the station is detached, the sling is installed through the station mouth. Disengager 3. The trimmer uses the effect trimmer to adjust and grind the sample after grinding and grinding the sample. The taper angle of the sample is 30°10′, and then the trimmer is finely adjusted. 30°0′, the reading of the dial gauge calculated by equation (1): h=0.436mm. According to the calculation result, the adjustment rod is rotated, and then the sample is adjusted and the cone angle is measured as 30°1′. Meet the requirements. Transfer to the formal grinding of the workpiece and extract 3 measurements for the first batch of workpiece after grinding. The measurement results are: 30°1', 30°0'48", 30°0'40", which fully meets the requirements of the drawings. Precautions during grinding 1) When trimming the grinding wheel, the feed amount should not be too large to ensure the grinding performance of the grinding wheel and prolong the service life of the correcting cutter head. 2) Grinding wheel selection According to the material of the workpiece and the desired surface roughness value, the abrasive type and abrasive grain size should be selected. 3) The grinding wheel should be regularly corrected during the grinding process to ensure the correct angle and grinding performance of the grinding wheel. 4) Since the taper surface can only be cut and cut, the feed of the grinding wheel should be small when grinding. If it is too large, it will easily burn the surface. The above practice shows that in the ordinary universal cylindrical grinding machine, the special tooling is used for high-precision cone grinding, which is feasible in the process and economically reasonable.

The working principle of the dresser The schematic diagram of the dresser of the grinding wheel is installed on the MG1432A universal cylindrical grinding head head frame, so that the fixed bottom plate of the corrector is parallel with the work table of the grinding machine, and the movable bottom plate is coarsely adjusted to make the center line of the modified cutting head The radial direction of the grinding wheel is 15°. The movement of the modified cutter head is driven by the trimmer's advance and retreat cylinders. It moves linearly on the standard guide rail (simulated dressing grinding wheel). Its stroke is controlled by the stroke switch. The movement speed is adjusted by adjusting the speed control valve. change. The oil circuit system of the dresser is realized by branching out the hydraulic system of the grinding machine itself.
