Description

Technical Field

[0001] The utility model relates to the field of flat grinding fixtures, in particular to a flat surface flat grinding processing device. Background Art

[0002] There are many centering pin structures used for connection and positioning in precision hydraulic valve products. The key core parts are two symmetrical flat surfaces. During processing, not only the thickness of the flat surface is required to be precisely matched with the mating parts, but also the flatness and parallelism requirements must be met. The traditional processing method is to hold the parts by hand after rough processing, grind the flat surface on the ground cast iron, and complete the fine processing to ensure the requirements of various indicators. Because the parts are small, hand-held processing has poor stability, and is prone to problems such as deflection, jitter, and uneven removal of excess. The operator is extremely demanding, and the product quality is unstable, making it difficult to meet the requirements of precision processing, and it is easy to cause quality problems such as scrap.

[0021] The following is a specific embodiment of the present invention. People familiar with the technology can easily understand the other advantages and functions of the present invention from the contents disclosed in this specification. Obviously, the described embodiment is a part of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] In order to better implement the utility model, the following Figure 1 , 2 , 3. The utility model is described in detail.

[0023] A flat surface grinding device, the device is in the shape of a round cake, with a through hole in the center, the through hole shape is composed of two parallel straight sides and two arc sides; and the device is cut along one of the straight sides of the through hole;

[0024] The device is sleeved on the part to be flattened, and the cutting surface is matched with the flat surface.

[0025] The connection between the remaining straight edge of the through hole and the two arc edges is a concave rounded transition to prevent the edges of the parts from getting stuck.

[0026] The thickness of the device is 3 / 4 to 1 times the length of the flat surface of the part, and can effectively support the flat surface of the part to be on the same horizontal plane to ensure the final flatness processing requirements.

[0027] The distance between the two straight edges of the through hole of the device is 0.05mm to 0.10mm smaller than the distance between the two flat surfaces of the part to be flattened, ensuring that only the surface of the part to be processed contacts the grinding strip during flattening, ensuring that the device is not flattened, preventing pollution of the flattening environment, and causing poor roughness of the surface to be processed.

[0028] The two arc edges of the through hole of the device are matched with the outer surface of the part to be flattened, and the matching clearance is 0.01mm-0.03mm, which is convenient for loading and unloading, and the switching is simple and fast.

[0029] During processing, place the grinding cast iron flat on the marble platform, put the part into the flat grinding tool, and apply diamond abrasive paste on the exposed side of the part;

[0030] Use your left hand to press the top of the flat grinding tooling to make the surface of the part coated with corundum grinding paste fit the surface of the cast iron. Use your right hand to move the part back and forth to remove the fine wire cutting and electro-erosion layer. The movement process must be smooth to avoid shaking the part back and forth.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the field can easily think of various equivalent modifications or substitutions within the technical scope disclosed in the utility model, and these modifications or substitutions should be included in the protection scope of the utility model.
