Description

Technical Field

[0001] The utility model relates to the technical field of turning tools, in particular to a high-pressure inner-cooling press plate turning tool. Background Art

[0002] A turning tool is a tool with a cutting part used for turning. It is one of the most widely used tools in cutting. The cutting part of a turning tool consists of a main cutting edge, a secondary cutting edge, a rake face, a main flank face, a secondary flank face, and a tool tip angle.

[0003] When the turning tool is processed, the temperature of the turning tool will increase. In order to reduce the temperature of the turning tool, some turning tools will set a flow channel on the pressure plate. The cooling water from the internal cooling channel on the tool body passes through the flow channel on the pressure plate to reach the cutting edge of the turning tool to cool the turning tool.

[0004] After the production of the turning tool pressure plate in the prior art, one end of the water inlet of the turning tool pressure plate needs to be polished to adapt to the water outlet end of the internal cooling channel of the tool body. During this operation, it is not only necessary to ensure that the water inlet end of the turning tool pressure plate is a plane, but also to ensure that the angle of the plane and the plane at the water outlet end of the internal cooling channel of the tool body are adapted. The processing is difficult and very inconvenient, so a high-pressure internal cooling pressure plate turning tool is needed. Utility Model Content

[0005] In view of the problems existing in the prior art, the utility model solves the problems with the following technical structure.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A high-pressure internally-cooled pressure plate turning tool, comprising: a tool body, an adapter plate and a pressure plate, wherein a mounting groove is provided on the tool body, the bottom of the cross section of the mounting groove is arc-shaped, and the outlet of the internal cooling channel of the tool body is located at the bottom of the mounting groove;

[0008] The annular surface of the adapter plate includes a receiving plane and an arc surface adapted to the bottom of the mounting groove, and a through hole adapted to the outlet of the inner cooling channel of the tool body is provided through the adapter plate, and the inlet end and the outlet end of the through hole are respectively located on the arc surface and the receiving plane, and the adapter plate is placed in the mounting groove;

[0009] The pressing plate is placed on the blade body, and the pressing plate comprises a mounting plane. A flow channel adapted to the through hole is arranged on the pressing plate, and an inlet end of the flow channel is located at the mounting plane.

[0010] It is further characterized in that

[0011] The knife body is provided with a limiting column in the installation groove, the adapter plate is provided with a waist-shaped hole, and the adapter plate is sleeved on the limiting column through the waist-shaped hole.

[0012] The cutter body is provided with two internal cooling channels, two through holes and two flow channels.

[0013] The end of the pressing plate is provided with three water cooling outlets, and the three water cooling outlets are connected with the flow channel.

[0014] The diameter of the water cooling outlet is smaller than the diameter of the flow channel.

[0015] The pressing plate is fixed on the cutter body by bolts.

[0016] The pressure plate includes two protrusions, and the inlet ends of the two flow channels are respectively located at the suspended ends of the two protrusions.

[0017] The pressing plate is made of metal.

[0018] The pressing plate is made of plastic.

[0019] The pressing plate is integrally formed by 3D printing.

[0020] The above structure of the utility model can achieve the following beneficial effects:

[0021] An adapter plate is used to connect the tool body and the pressure plate. The through holes on the adapter plate lead the cooling water at the internal cooling channel of the tool body to the flow channel of the pressure plate. The arc surface of the adapter plate fits tightly with the bottom of the installation groove, and the receiving plane fits tightly with the installation plane. Since the adapter plate is rotatably set in the installation groove, it is only necessary to ensure that the flatness of the installation plane of the pressure plate is matched with the flatness of the receiving plane during processing. The rotation of the adapter plate can compensate for the angular error between the receiving plane and the installation plane, which reduces the manufacturing difficulty of the pressure plate and improves the processing efficiency.

[0028] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0029] It should be noted that the terms "including" and "having" and any variations thereof in the specification and claims of the present invention and the above-mentioned drawings are intended to cover non-exclusive inclusions. For example, a process, method, apparatus, product or equipment comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or equipment.

[0030] The following is combined with Figure 1-5 This application is described in further detail.

[0031] refer to Figure 1-4 A high-pressure internally-cooled pressure plate turning tool shown in the figure comprises: a tool body 1, an adapter plate 2 and a pressure plate 3, wherein a mounting groove 11 is provided on the tool body 1, the bottom of the cross section of the mounting groove 11 is arc-shaped, and the outlet of the internal cooling channel of the tool body 1 is located at the bottom of the mounting groove 11; the annular surface of the adapter plate 2 comprises a receiving plane 21 and a circular arc surface 22 adapted to the bottom of the mounting groove 11, and a through hole 23 adapted to the outlet of the internal cooling channel of the tool body 1 is provided through the adapter plate 2, and the inlet end and the outlet end of the through hole 23 are respectively located on the circular arc surface 22 and the receiving plane 21, and the adapter plate 2 is placed in the mounting groove 11; the pressure plate 3 is placed on the tool body 1, and the pressure plate 3 comprises a mounting plane 31, and a There is a flow channel 32 adapted to the through hole 23, and the inlet end of the flow channel 32 is located at the installation plane 31. In this way, the adapter plate 2 is used to connect the tool body 1 and the pressure plate 3, and the through hole 23 on the adapter plate 2 guides the cooling water at the internal cooling channel of the tool body 1 to the flow channel 32 of the pressure plate 3; the arc surface 22 of the adapter plate 2 fits tightly with the bottom of the installation groove 11, and the receiving plane 21 fits tightly with the installation plane 31. Since the adapter plate 2 is rotatably set in the installation groove 11, it is only necessary to ensure that the flatness of the installation plane 31 of the pressure plate is adapted to the flatness of the receiving plane 21 during processing. The rotation of the adapter plate 2 can make up for the angular error between the receiving plane 21 and the installation plane 31, which reduces the manufacturing difficulty of the pressure plate and improves the processing efficiency.

[0032] refer to Figure 2 ,3 As shown in Figure 5, the knife body 1 is provided with a limiting column 4 in the mounting groove 11, and the adapter plate 2 is provided with a waist-shaped hole 24. The adapter plate 2 is sleeved on the limiting column 4 through the waist-shaped hole 24. In this way, the adapter plate 2 is limited by the limiting column 4 so that the adapter plate 2 can only rotate but cannot translate.

[0033] Further optimization is that Figure 2 , 4 As shown in FIG. 5 , in order to improve the water cooling effect, the inner cooling channel, the through hole 23 and the flow channel 32 of the tool body 1 are each provided with two.

[0034] like Figure 4 As shown, three water cooling outlets 33 are provided at the end of the pressure plate 3, and the three water cooling outlets 33 are connected with the flow channel 32. The diameter of the water cooling outlet 33 is smaller than the diameter of the flow channel 32. In this way, the diameter of the three internal cooling outlets 33 is small, which is equivalent to compressing the water flow diameter inside the pressure plate 3 and increasing the water flow pressure.

[0035] like Figure 1 As shown, the pressing plate 3 is fixed to the cutter body 1 by bolts, so that the pressing plate 3 is easy to disassemble and assemble.

[0036] like Figure 4 As shown, the pressing plate 3 includes two protrusions 34, and the inlet ends of the two flow channels 32 are respectively located at the suspended ends of the two protrusions 34. In this way, when the pressing plate 3 is installed, the two protrusions 34 are placed at the opening of the installation groove 11, which makes it easy to position the pressing plate 3.

[0037] It is further optimized that the pressing plate 3 can be made of metal, plastic or ceramic, and since the flow channel 32 is arranged inside the pressing plate 3, it can be integrally formed by 3D printing, which not only has high processing efficiency but also low cost.

[0038] The working principle of the utility model is as follows: an adapter plate 2 is used to connect the tool body 1 and the pressure plate 3, and the through hole 23 on the adapter plate 2 guides the cooling water at the inner cooling channel of the tool body 1 to the flow channel 32 of the pressure plate 3; the arc surface 22 of the adapter plate 2 is tightly fitted with the bottom of the installation groove 11, and the receiving plane 21 is tightly fitted with the installation plane 31. Since the adapter plate 2 is rotatably set in the installation groove 11, it is only necessary to ensure that the flatness of the installation plane 31 of the pressure plate is adapted to the flatness of the receiving plane 21 during processing. The rotation of the adapter plate 2 can make up for the angular error between the receiving plane 21 and the installation plane 31, which reduces the manufacturing difficulty of the pressure plate and improves the processing efficiency.

[0039] The above are only preferred embodiments of the present application, and the present invention is not limited to the above embodiments. It is understood that other improvements and changes directly derived or associated by those skilled in the art without departing from the spirit and concept of the present invention should be considered to be included in the protection scope of the present invention.
