Step two: carrying out vacuum heat treatment processing on the vehicle part product obtained in the first step; the heating temperature of the spring steel is 810-830 ℃ during heat treatment, and the heat preservation time is determined according to the charging mode. The tempering temperature is 320 ℃, and oil cooling is adopted after full tempering, so that tempering brittleness can be reduced. The hardness is required to be between HRC45 and 45 Rockwell hardness.
Step three: machining the workpiece subjected to the heat treatment in the second step by using a precise CNC; during machining, a professional fixture is adopted to fix a machined product, the outer ring locating surface 12 and the locating edge of the fixture locating bolt 13, the clamping position 15 and the bearing bead are required to be machined, and meanwhile, the conical adjusting surface on the clamping head 5, the screw hole site and the screw hole site avoidance space are machined. In addition, the locating surface 12 is reserved with a single-side 0.1 allowance during machining, and is used for machining by a post-process precision grinding machine.
Step four: grinding the product obtained in the third step by using a precise plane hand-operated grinding machine; the contact surfaces which are contacted with each other are ground, and the flatness tolerance is ensured to be within 0.005 MM. The ground positioning surface 12 is reversely placed on the grinding machine to grind the high-precision positioning surface 12 on the balance base 1 and the connecting seat 6, and the parallelism of the high-precision positioning surface 12 is within 0.002 MM. Because the temperature of the workpiece cannot exceed 50 degrees when the workpiece is processed by a precision grinder, the workpiece can deform by more than 50 degrees, the workpiece is required to be cooled by spraying alcohol when the workpiece is processed by the grinder, the workpiece is kept not to deform, and the precision is controlled within 0.005 MM.
Step five: precise external grinding; and (3) clamping the product obtained in the step four on a precision clamp for slow wire feeding processing, wherein the installation precision is within 0.002 MM. The precise external cylindrical grinding wheel is a resin bond diamond grinding wheel, has high hardness, high strength and strong grinding capability, is mainly used for grinding high-hardness and hard alloy, nonmetallic materials and cutting hard and brittle hard alloy, and has high grinding efficiency. Meanwhile, the grinding wheel is relatively slow in consumption, good in self-sharpening property, small in heating value during grinding, not easy to block, capable of reducing the phenomenon of work burn during grinding, and has certain elasticity, so that the surface roughness of a workpiece is improved, and the grinding wheel is mainly used for working procedures such as fine grinding, semi-fine grinding, knife grinding and polishing. When the grinding wheel is used for processing the outer diameter, the circle run-out precision is ensured to be within 0.002MM, and the planeness, the parallelism, the roundness and the perpendicularity are ensured to be within 0.003 MM.
Step six: surface protection of the workpiece; and (3) the processed product passes through a sand blasting machine, and is sprayed out by using glass sand with 240# particles under the pressure of 3 kg of sand blasting air pressure. The positioning surface 12 of the balance base 1 needs to be protected in the sand blasting process, and then the sand blasting treatment is carried out to achieve the purposes of unifying the surface appearance of the product and protecting the surface. And finally, placing the sand-blasted product on a tool table, spraying the rust-preventive oil, ensuring that the rust-preventive oil is uniform on the surface of the whole product, packaging the product with oil paper, and storing the product in a clamp box.
While the preferred embodiment of the present invention has been described in detail, the present invention is not limited to the embodiments, and those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention, and these equivalent modifications or substitutions are included in the scope of the present invention as defined in the appended claims.
