Description

Technical Field

[0001] This utility model belongs to the field of cutting tool technology, and in particular relates to a double-hole internal groove cutting tool structure. Background Technology

[0002] In the field of water pipe fitting processing, Swiss-type lathes are widely used due to their high processing efficiency. As the core processing component of a Swiss-type lathe, the rationality of its structure directly affects processing efficiency and product quality. Currently, most cutting tools used for processing water pipe fittings on Swiss-type lathes adopt an integrated structure design; the cutting head and the tool body of such tools are an inseparable, integral structure.

[0003] In actual machining, the cutting head, as the component directly involved in cutting, is highly susceptible to wear and chipping due to prolonged high-speed friction and collision with the water pipe connector workpiece. When the cutting head is damaged, the operator needs to remove the entire one-piece cutting tool from the Swiss-type lathe for replacement. Because one-piece cutting tools lack a precise positioning reference structure, a tool setting operation must be performed again after replacing the new tool. During tool setting, the operator needs to repeatedly adjust the tool's position parameters using specialized measuring tools to ensure that the cutting trajectory meets the machining requirements of the water pipe connector. This tool setting process often consumes a significant amount of time, interrupting the continuous machining flow of the water pipe connector and reducing overall production efficiency. Utility Model Content

A first fixing hole 11 and a second fixing hole 12 are provided on the cutter body 1, and the first fixing hole 11 and the second fixing hole 12 are arranged sequentially.

[0033] The tool body 1, the tool head 2, and the positioning head 3 are integrally formed from cemented carbide material to ensure the stability of the overall structure. The tool head 2 is fixed to one end of the tool body 1, and the positioning head 3 is fixed to the other end of the tool body 1.

During machining, a circular arc milling cutter is used for milling to ensure a smooth transition.

[0034] A left clearance groove 21 and a right clearance groove 22 are machined and provided at the connection between the cutter head 2 and the cutter body 1. The left clearance groove 21 is located inside the cutter head 2 and its depth is 0.5-3mm, preferably 1.4mm. The right clearance groove 22 is located outside the cutter head 2 and its depth is adapted to the left clearance groove 21 to meet the requirement of avoiding cutting interference.

[0035] In another embodiment of this utility model, a first fixing hole 11 and a second fixing hole 12 are sequentially disposed in the middle of the tool body 1. Both the first fixing hole 11 and the second fixing hole 12 are inclined and form a locking slope. The diameter of the first fixing hole 11 and the second fixing hole 12 is 2-8 mm, preferably 4.25 mm, and the distance between the center holes of the first fixing hole 11 and the second fixing hole 12 is 6-12 mm, preferably 9.05 mm.

[0036] The tool body 1 has a first fixing hole 11 and a second fixing hole 12 sequentially arranged in the middle. A drilling machine with an inclined drill bit is used to machine both fixing holes so that they are inclined and form a locking bevel. The diameter of the first fixing hole 11 and the second fixing hole 12 is controlled to be 4.25 mm. A precision ranging tool is used to determine the center distance between the two fixing holes, ensuring that the distance is 9.05 mm.

[0037] In another embodiment of this utility model, the width of the tool body 1 is 5-12mm, preferably 8.15mm, and the thickness of the tool body 1 is 2-8mm, preferably 5mm.

[0038] In another embodiment of this utility model, the blade head 2 is provided with a blade tip arc-shaped portion 23 at both ends. The blade tip arc-shaped portion 23 is arc-shaped and the radius of the blade tip arc-shaped portion 23 is 0.1-2mm, preferably 0.15mm.

[0039] In another embodiment of this utility model, the cutter head 2 is provided with a cutting surface 24, which forms a cutting angle α with the cutter body 1. The angle of the cutting angle α is 1-10°, preferably 5°. This angle can reduce the cutting resistance when the cutter head 2 cuts into the workpiece, reduce the plastic deformation of the workpiece material, and improve the surface finish of the end face groove.

[0040] In another embodiment of this utility model, the length of the blade 2 is 1-8mm, preferably 4mm, and the width of the blade 2 is 1-7mm, preferably 3.2mm.

[0041] In another embodiment of this utility model, the depth of the left clearance groove 21 is 0.5-3mm, preferably 1.4mm.

[0042] In another embodiment of this utility model, the tool body 1 is provided with a positioning inclined surface 13, which is located on one side of the positioning head 3. The inclination angle of the positioning inclined surface 13 is adapted to the mounting groove angle of the Swiss-type lathe to ensure a tight fit during installation.

[0043] In another embodiment of this utility model, an arc-shaped transition portion 14 is provided between the tool body 1 and the positioning head 3. The arc-shaped transition portion 14 is arc-shaped and has a radius of 0.1-2 mm, preferably 0.2 mm. The arc-shaped transition portion 14 can reduce stress concentration at the connection between the positioning head 3 and the positioning inclined surface 13, and improve the structural stability of the tool body 1.

[0044] The installation and use process of the vertically mounted end-face grooved insert structure provided in this application is as follows:

[0045] Installation procedure: Align the positioning head 3 of this double-hole inner groove cutter head structure with the cutter bar on the Swiss Army machine, so that the positioning bevel 13 fits against the corresponding surface of the cutter bar. Then, pass the bolts of the matching specifications through the first fixing hole 11 and the second fixing hole 12. When tightening the bolts, use the locking bevel of the fixing hole to enhance the locking effect, so that the cutter head is firmly fixed on the Swiss Army machine.

[0046] Machining operation: Start the Swiss-type lathe. The cutting surface 24 of the cutter head 2 smoothly cuts into the water pipe connector 4 workpiece under the action of a cutting angle of 1-10°. The arc-shaped part 23 of the cutter tip performs arc-shaped cutting on the inner groove of the water pipe connector 4. During the machining process, the left clearance groove 21 and the right clearance groove 22 prevent friction interference between the cutter head 2 and the non-cutting part of the workpiece from the inside and outside of the cutter head 2, respectively, to ensure a smooth cutting process.

[0047] Tool replacement operation: When the tool head 2 is worn, unscrew the bolts in the first fixing hole 11 and the second fixing hole 12, remove the worn tool, and replace it with a new tool of the same specification. Due to the positioning effect of the positioning head 3 and the positioning inclined surface 13, the cutting position of the new tool is consistent with that of the original tool after installation. There is no need to re-set the tool. After installation, the processing of the water pipe joint 4 can be resumed.

[0048] The vertically mounted end face grooved insert structure provided in this application avoids interference between the inner side of the insert 2 and the workpiece step surface and the outer side of the insert 2 and the workpiece outer surface by setting a left clearance groove 21 and a right clearance groove 22 between the insert 2 and the cutter body 1, respectively, thereby reducing processing resistance and the risk of workpiece scratches and ensuring the stability of the processing process.

[0049] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
