Description

Technical Field

[0001] This utility model relates to an alloy reamer, specifically an alloy reamer with a self-lubricating coating, belonging to the field of machining tool technology. Background Technology

[0002] A reamer can be used to enlarge or reduce the shape of a drilled hole. Depending on the application, it can be used for roughing or finishing. It is a spiral shape, like the straight shape of a drill bit. In the machining process, the reamer plays a vital role as a tool for finishing drilled, bored, or enlarged holes.

[0003] In the prior art, such as the carbide reamer disclosed in announcement number CN222154147U, the feed rate during the reamer machining process is reduced, the temperature rise rate of the reamer itself is slowed down, the possibility of reamer damage is reduced, and the service life of the reamer is improved. The above-mentioned carbide reamer is an integral structure. During use, when the cutting edge of the milling cutter is worn or damaged, the entire milling cutter needs to be replaced, which causes great waste and increases the processing cost. Utility Model Content

[0004] The purpose of this invention is to provide an alloy reamer with a self-lubricating coating to solve the problem that the alloy reamer in the above-mentioned device has an integral structure, and when the cutting edge of the milling cutter is worn or damaged during use, the entire milling cutter needs to be replaced, resulting in great waste and increased processing costs.

[0006] A cutting part is fixedly installed at one end of the tool holder. A cutting tool is provided on the surface of the cutting part. An insert groove adapted to the cutting tool is opened on the surface of the cutting part. The cutting tool is embedded in the insert groove and fixed by a fixing bolt. The surface of the cutting part is coated with a self-lubricating coating.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0022] like Figures 1 to 5 As shown, an alloy reamer with a self-lubricating coating includes a handle 1;

[0023] A cutting part 2 is fixedly installed at one end of the tool holder 1. A cutting blade 3 is provided on the surface of the cutting part 2. An insert groove 13 adapted to the cutting blade 3 is opened on the surface of the cutting part 2. The cutting blade 3 is embedded in the insert groove 13 and fixed by a fixing bolt 8. The surface of the cutting part 2 is coated with a self-lubricating coating.

[0024] The tool holder 1 and the cutting part 2 are fixedly installed to ensure that the overall structure will not loosen or shift during high-speed, high-load cutting, thus guaranteeing machining accuracy and stability. The cutting tool 3 is embedded in the fitting slot 13 and secured by the fixing bolt 8, further preventing the cutting tool 3 from shifting or falling off under cutting force and extending tool life. The surfaces of the cutting part 2 and the cutting tool 3 are coated with a self-lubricating coating, which can form a lubricating film between the cutting tool 3 and the workpiece, reducing the coefficient of friction and reducing cutting heat generation. At the same time, when the cutting tool 3 is worn or damaged, it is not necessary to replace the entire reamer. Simply loosen the fixing bolt 8 to remove the damaged cutting tool 3 from the fitting slot 13 and replace it with a new cutting tool 3. This avoids the waste of discarding the entire reamer due to tool head damage and significantly reduces tool procurement costs.

[0025] Furthermore, a chip groove 5 is provided on the surface of the cutting part 2 and on one side of the cutting tool 3.

[0026] The chip groove 5 is adjacent to the cutting tool 3. When the cutting tool 3 performs cutting operations on the workpiece, the chips can be immediately contained in the chip groove 5. This effectively avoids the accumulation of chips in the cutting area, prevents the chips from rubbing against the machined surface with the cutting tool 3, thereby reducing surface roughness and ensuring machining accuracy.

[0027] Furthermore, a tapered guide head 4 is installed at the end of the cutting part 2 away from the tool holder 1. A guide groove 9 is provided on the surface of the tapered guide head 4, and the guide groove 9 is connected to the chip groove 5.

[0028] When the reamer begins machining the inner hole of the workpiece, the tapered guide head 4, with its tapered structure, can quickly and accurately insert into the hole to be machined, providing accurate initial positioning for the subsequent cutting operation of the reamer. This process effectively avoids the possible deviation or wobbling of the reamer when entering the hole, ensuring that the cutting tool 3 of the cutting part 2 can cut along the correct trajectory, thereby significantly improving machining accuracy. Example 2

[0029] Improvements based on Example 1:

[0030] Furthermore, the tool holder 1 is provided with an internal cooling channel 6, and the outlet of the internal cooling channel 6 is located at the end of the tapered guide head 4.

[0031] Coolant is sprayed from the end of the tapered guide head 4, which generates an additional impact force on the chips. During the cutting process, the chips are more easily dispersed by the coolant and carried out of the chip groove 5 and guide groove 9, preventing chips from accumulating in the hole.

[0032] Furthermore, the surface of the cutting part 2 is provided with a spray hole 7, which is connected to the internal cooling channel 6, and the outlet of the spray hole 7 is inclined toward the cutting tool 3.

[0033] The outlet of the spray hole 7 is inclined towards the cutting tool 3, which enables the coolant delivered from the internal cooling channel 6 to be accurately sprayed onto the cutting edge of the cutting tool 3 and the contact area between the cutting edge and the workpiece, preventing chips from accumulating in the cutting area and affecting machining accuracy and surface quality.

[0034] Furthermore, the surface of the tapered guide head 4 is provided with a fastener 11, and the surface of the fastener 11 is threaded with a fixing bolt 12. The fastener 11 is threadedly connected to the surface of the tapered guide head 4 through the fixing bolt 12. The surface of the cutting tool 3 is provided with a groove 10 that is compatible with the fastener 11.

[0035] The cutting tool 3 is connected to the tapered guide head 4 by fastener 11, making the structure of the cutting part 2 more compact and stable, and enhancing the overall rigidity of the tool.

[0036] It should be noted that the composition of the self-lubricating coating can be based on the authorized patent, authorized (announcement) number: CN109267042B Preparation method of wear-resistant self-lubricating coating for steel materials. The composition of the wear-resistant self-lubricating coating is consistent with that of the self-lubricating coating in the application document itself, and will not be repeated here.

[0037] Working principle: The alloy reamer is installed on a high-precision CNC machine tool and connected to the machine tool spindle via the tool holder 1. When the machine tool starts and the reamer rotates at high speed, the tapered guide head 4 first enters the hole to be machined in the workpiece, guiding the reamer to be precisely positioned. The cutting tool 3 of the cutting part 2 cuts the hole wall during rotation. The self-lubricating coating effectively reduces the friction between the cutting tool 3 and the workpiece, reducing heat generation. The chips generated by cutting are discharged through the chip groove 5 and the guide groove 9. At the same time, coolant is sprayed into the cutting area through the internal cooling channel 6 and the spray hole 7 to cool and lubricate the cutting tool 3, greatly improving machining efficiency and machining accuracy, and extending the service life of the reamer.
