Description

Technical Field

[0001] The present invention relates to the field of oilstone clamps, and particularly to an integrated oilstone clamp and its processing method. Background Art

[0002] Oilstones are often used in the field of high-precision machining, mainly applicable to the forming grinding of the instrument industry, precision parts, micro-tools, tools, precision abrasives, etc. The surface roughness of the processed precision can reach about 0.05 μm, making the surface of the processed workpiece smoother and more delicate.

[0003] When in use, the oilstone needs to be clamped to ensure the stability and controllability during grinding. The existing ways of using oilstone clamps include hand-held ones. For example, an oilstone holder with the application number 201020183369.8 operates through a ferrule cooperating with a clamping pen and a wedge part. It is not suitable for mechanical processing, and after long-term use, the ferrule is worn in multiple directions, which easily causes the oilstone to loosen. The existing oilstone clamps applicable to mechanical equipment processing and grinding have increased lateral wear due to the high grinding frequency. The traditional oilstone clamps are severely worn after a period of use, easily causing the oilstone to loosen and the grinding effect to decline. Therefore, an integrated oilstone clamp is provided. Summary of the Invention

[0004] The technical problem to be solved by the present invention is: to provide an integrated oilstone clamp with a simple structure, convenient use, wear resistance, and a long service life, and its processing method.

[0005] To solve the above technical problem, the present invention is solved by the following technical solutions: an integrated oilstone clamp, including an integrally formed oilstone clamp body. The oilstone clamp body is provided with an installation cavity for inserting an oilstone. Installation grooves are provided on the opposite inner side walls of the installation cavity. A wear-resistant member made of diamond is welded and fixed in the installation groove, and the relatively arranged wear-resistant members are in contact with the oilstone inserted into the installation cavity.

[0006] Furthermore, the horizontal cross-section of the installation cavity is square, and installation grooves are provided on the inner side walls of the installation cavity. The advantage is that by setting the installation grooves with a square cross-section, the relative arrangement of the wear-resistant members can be facilitated, thereby more reliably avoiding the contact between the oilstone and the oilstone clamp body during the use of the oilstone, improving the wear resistance and service life of the oilstone clamp.

[0007] Furthermore, the wear-resistant member protrudes from the installation groove and extends into the installation cavity. The benefit is that by setting the wear-resistant member extending into the installation cavity, the contact between the oilstone and the oilstone clamp body can be further avoided, further extending the service life of the oilstone clamp.

[0008] Further, an avoidance groove is provided between two adjacent wear-resistant parts. The advantage is that the wear-resistant parts can stabilize the oilstone inserted into the installation cavity, and the setting of the avoidance groove can effectively avoid interference during the installation, welding, and fixing of the wear-resistant parts, especially when there are machining errors in the dimensions of the wear-resistant parts. Since the wear-resistant parts made of diamond are highly hard and wear-resistant, debris will be generated during the machining and grinding of the workpiece by the oilstone due to the friction between the oilstone and the wear-resistant parts. The debris and dust can also be discharged outward through the provided avoidance groove.

[0009] Further, opposite bosses are provided on the inner side wall of the installation cavity, and the bosses are located between two arranged installation grooves; the advantage is that the bosses provided can limit the oilstone inserted into the installation cavity in one direction, and the relatively arranged wear-resistant parts can limit it in the other direction, thereby reducing the use of diamond, and the protruding part can extend the wear time and increase the service life.

[0010] A processing method for an integrated oilstone clamp, characterized by comprising the following steps:

[0011] Step 1: Machine and turn the workpiece to be processed to obtain an oilstone clamp body with a cubic installation cavity inside.

[0012] Step 2: Perform secondary processing on the oilstone clamp body obtained in Step 1 to obtain an oilstone clamp body with opposite installation grooves on the inner side wall of the installation cavity.

[0013] Step 3: Apply a soldering flux to the oilstone clamp body obtained in Step 2, evenly apply the soldering flux in the installation grooves, and embed the wear-resistant parts made of diamond that match the installation grooves into the installation grooves, and the soldering flux is closely attached to the wear-resistant parts.

[0014] Step 4: Insert a graphite rod into the installation cavity in Step 3, and the graphite rod is closely attached to and abuts against the wear-resistant parts to ensure that the wear-resistant parts are fixed in the installation grooves.

[0015] Step 5: Perform preheating and welding treatment on the oilstone clamp body obtained after Step 4 at a preheating temperature. The preheating temperature is gradually increased from room temperature to 180 °C within the preheating time, and the first constant temperature is maintained so that the current temperature is maintained between 180 °C and 190 °C.

[0016] Step 6: Perform fusion welding treatment on the oilstone clamp that has completed the preheating and welding treatment at a fusion temperature. The fusion temperature is gradually increased from the temperature at the end of the preheating and welding treatment to 720 °C within the fusion time, and the second constant temperature is maintained so that the current temperature is maintained between 700 °C and 750 °C, so that the soldering flux is completely melted to ensure seamless fitting between the wear-resistant parts and the oilstone clamp body.

[0017] Step 7: After the fusion welding process is completed, let the oil stone clamp stand still so that it gradually cools down to room temperature within the standing time.

[0018] Step 8: Carry out dredging treatment on the oil stone clamp obtained in Step 7, remove the graphite rod that abuts against the wear-resistant part in the installation cavity, and carry out polishing treatment on the oil stone clamp after standing still.

[0019] Furthermore, the preheating time in Step 5 is 15 - 17 minutes, and the time for the first constant temperature maintenance is 5 - 10 minutes.

[0020] Furthermore, the fusion time in Step 6 is 50 - 60 minutes, and the time for the second constant temperature maintenance is 3 - 5 minutes; the standing time in Step 7 is 50 - 60 minutes.

[0021] Furthermore, each inner side wall of the installation cavity is provided with an installation groove, and wear-resistant parts are respectively and correspondingly embedded in the installation grooves; the advantage is that wear resistance can be better achieved by providing installation grooves on each inner side wall, thereby improving the service life of the oil stone clamp.

[0022] Furthermore, the wear-resistant part protrudes inward from the side wall of the installation cavity or is flush with the side wall of the installation cavity.

[0023] Compared with the prior art, the present invention has the following beneficial effects: By setting an integrally formed oil stone clamp body, the stability and anti-deformation ability of the oil stone clamp body itself can be effectively improved, especially effectively extending the service life during the machining process. At the same time, an installation cavity is provided in the oil stone clamp body. The wear-resistant parts composed of diamond provided on the inner side wall of the installation cavity can greatly improve the wear resistance of the oil stone clamp, that is, during the process of grinding the workpiece after inserting the oil stone, the wear of the oil stone on the oil stone clamp body, thereby reducing the scrap rate of the oil stone clamp. When the oil stone needs to be replaced later, only the oil stone needs to be disassembled, and the oil stone clamp can be reused, saving costs. Through the one-piece oil stone clamp processing method of the present invention, the reliability of welding and fixing the wear-resistant parts composed of diamond to the oil stone clamp body can be guaranteed, and the change error of the installation cavity size can be controlled, thereby ensuring the smooth insertion of the oil stone during later use, that is, temporarily supported by the graphite rod. Since the graphite rod is heat-resistant and has a soft texture, after the wear-resistant part is welded and fixed to the oil stone clamp body, the graphite rod can be taken out by ejecting or crushed and taken out. Even if graphite remains inside the wear-resistant part, it has little impact on the oil stone inserted into the installation cavity during later use and can play a lubricating role, reducing the wear of the oil stone on the oil stone clamp.
