Description

Technical Field

[0001] This application relates to the technical field of tool grinding, and particularly relates to a grinding positioning device and grinding equipment for a PCBN grooving tool. Background Art

[0002] The production of polycrystalline cubic boron nitride (PCBN) and its products is an important branch of the superhard material industry. Since PCBN tools were first introduced as cutting tool materials, they have gradually become the preferred tools for commonly solving difficult-to-machine materials. They can be used to machine difficult-to-machine materials such as hardened steel, cast iron, superalloy, and powder metallurgy materials after quenching. Nowadays, PCBN tools are gradually replacing traditional carbide tools and ceramic tools with many excellent characteristics such as high wear resistance, high corrosion resistance, high removal rate, and high cost performance, and are widely used in the field of ferrous metal processing in industries such as automotive, aviation, and shipbuilding.

[0003] Cutting off and grooving are important machining methods in turning. They have high requirements for tools. In existing cutting-off and grooving machining applications, due to their machining characteristics, traditional grooving tools have low rigidity, poor chip evacuation, tool chatter, tool breakage, and chipping often occur. This not only seriously affects machining safety and the surface quality of parts, but also reduces tool life and keeps tool costs high. In recent years, machining enterprises have generally found that grooving tools with PCBN material at the tool tip have advantages in machining conditions such as oil grooves, relief grooves, and external turning of difficult-to-machine materials such as hardened steel, cast iron, superalloy, and powder metallurgy materials after quenching that are incomparable to traditional alloy grooving tools. The anti-vibration, high strength, and high hardness demonstrated by PCBN grooving tools are the future development trend of grooving tools.

[0004] However, PCBN grooving tools need to be ground during the manufacturing process, and the PCBN grooving tools need to be positioned during grinding. However, the existing positioning devices have relatively poor stability in fixing PCBN grooving tools, which will affect the production efficiency and machining quality of PCBN grooving tools.

Detailed implementation manners

[0032] The following detailed implementation manners are provided to help readers obtain a comprehensive understanding of the methods, devices, and / or systems described herein. However, after understanding the disclosure of this application, various changes, modifications, and equivalents of the methods, devices, and / or systems described herein will be obvious. For example, the order of operations described herein is merely exemplary and is not limited to the order set forth herein. Rather, changes that will be obvious after understanding the disclosure of this application may be made, except for operations that must occur in a specific order. In addition, descriptions of features known in the art may be omitted for the sake of clarity and conciseness.

[0033] The features described herein may be implemented in different forms and should not be construed as limited to the examples described herein. Rather, the examples described herein are provided only to illustrate some of the many possible ways of implementing the methods, devices, and / or systems described herein that will be obvious after understanding the disclosure of this application.

[0034] Throughout the specification, when an element (such as a layer, region, or substrate) is described as "on" another element, "connected to" another element, "bonded to" another element, "above" another element, or "covering" another element, it may be directly "on" another element, "connected to" another element, "bonded to" another element, "above" another element, or "covering" another element, or there may be one or more other elements therebetween. In contrast, when an element is described as "directly on" another element, "directly connected to" another element, "directly bonded to" another element, "directly above" another element, or "directly covering" another element, there may be no other elements therebetween.

[0035] As used herein, the term "and / or" includes any one of the listed related items and any combination of any two or more of them.

[0036] Although terms such as "first", "second", and "third" may be used herein to describe various elements, components, regions, layers, or sections, these elements, components, regions, layers, or sections are not limited by these terms. Rather, these terms are only used to distinguish one element, component, region, layer, or section from another. Thus, a first element, component, region, layer, or section referred to in the examples described herein may also be termed a second element, component, region, layer, or section without departing from the teachings of the examples.

[0037] For ease of description, spatial relationship terms such as "above", "upper", "below", and "lower" may be used herein to describe the relationship of one element to another as shown in the figures. Such spatial relationship terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, an element described as "above" or "upper" relative to another element will then be "below" or "lower" relative to the other element. Thus, the term "above" includes both the orientation of "above" and "below" depending on the spatial orientation of the device. The device may also be positioned in other ways (e.g., rotated 90 degrees or at other orientations), and the spatial relationship terms used herein will be interpreted accordingly.

[0039] Variations in the shapes shown in the figures may occur due to manufacturing techniques and / or tolerances. Thus, the examples described herein are not limited to the specific shapes shown in the figures but include changes in shape that occur during manufacturing.

[0040] The features of the examples described herein may be combined in various ways that will be apparent after understanding the disclosure of this application. In addition, although the examples described herein have a variety of configurations, other configurations are possible as will be apparent after understanding the disclosure of this application.

[0041] The following will be combined with Figures 1 to 7Describe the grinding positioning device for the PCBN grooving tool of the present application. Among them, the first direction L1 intersects with the second direction L2, and the third direction L3 intersects with the plane determined by the first direction L1 and the second direction L2. Preferably, the first direction L1, the second direction L2, and the third direction L3 are perpendicular to each other in pairs.

[0042] According to one aspect of the present application, a grinding positioning device for a PCBN grooving tool is provided. The grinding positioning device for the PCBN grooving tool is used for grinding the PCBN grooving tool 1. As Figures 1 to 7 shown, the grinding positioning device for the PCBN grooving tool includes a positioning member 2, a pressing member 3, and a fastening member 4. The positioning member 2 includes a first positioning surface S1 and a second positioning surface S2. A protruding portion 23 protruding from the first positioning surface S1 along the first direction L1 is formed on the first positioning surface S1. The second positioning surface S2 is located on one side of the first positioning surface S1 in the second direction L2. The pressing member 3 is hinged to the positioning member 2; the PCBN grooving tool 1 includes a first abutting surface S3 and a second abutting surface S4. A first positioning groove 11 is formed in the middle of the first abutting surface S3 in the third direction L3, and the first positioning groove 11 extends along the second direction L2; the first abutting surface S3 abuts against the first positioning surface S1, a part of the positioning member 2 extends into the first positioning groove 11, the second abutting surface S4 abuts against the second positioning surface S2, and the fastening member 4 can apply a force to the first end of the pressing member 3, so that the second end of the pressing member 3 abuts against the side of the PCBN grooving tool 1 facing away from the first positioning surface S1 in the first direction L1.

[0043] When the grinding positioning device for the PCBN grooving tool is in use, the first positioning surface S1 cooperates with the pressing member 3 to realize the positioning of the PCBN grooving tool 1 in the first direction L1. The second abutting surface S4 abuts against the second positioning surface S2, so as to realize the positioning of the PCBN grooving tool 1 in the second direction L2. A part of the PCBN grooving tool 1 extends into the first positioning groove 11, so as to realize the positioning of the PCBN grooving tool 1 in the third direction L3. In this way, the grinding positioning device for the PCBN grooving tool can realize the positioning of the PCBN grooving tool 1 in three directions of the first direction L1, the second direction L2, and the third direction L3, improving the stability of fixing the PCBN grooving tool 1, and further improving the production efficiency and processing quality of the PCBN grooving tool 1.

[0044] In the embodiment of the present application, as Figure 2 and Figure 3As shown, the positioning member 2 includes a first positioning member 21 and a second positioning member 22. One end of the first positioning member 21 is connected to the second positioning member 22 in the second direction L2. A part of the second positioning member 22 is higher than the first positioning member 21 in the first direction L1. The first positioning surface S1 is located on the side of the first positioning member 21 facing the crimping member 3 in the first direction L1, and the second positioning surface S2 is located on the side of the second positioning member 22 facing the first positioning member 21 in the second direction L2. In this way, the first positioning surface S1 can support the PCBN grooving tool 1, and one end of the PCBN grooving tool 1 in the third direction L3 abuts against the second positioning surface S2 to limit the PCBN grooving tool 1 in the second direction L2.

[0045] Furthermore, the dimension of the first positioning surface S1 in the second direction L2 is smaller than the dimension of the PCBN grooving tool 1 in the second direction L2, which makes the end of the PCBN grooving tool 1 facing away from the second positioning surface S2 protrude relative to the first positioning member 21 in the second direction L2, and can avoid interference between the positioning member 2 and the grinding wheel 9 in the grinding machine during grinding.

[0046] As Figure 2 、 Figure 3 and Figure 5 shown, the PCBN grooving tool grinding positioning device includes a rotating shaft 51 and two supporting members 52. The supporting members 52 protrude from the upper surface of the second positioning member 22 in the first direction L1. The two supporting members 52 are arranged at intervals in the third direction L3. The crimping member 3 is arranged between the two supporting members 52. The rotating shaft 51 passes through the crimping member 3 and the two supporting members 52, so that the crimping member 3 can rotate relative to the two supporting members 52.

[0047] Furthermore, the first end and the second end of the crimping member 3 are respectively located on both sides of the rotating shaft 51 in the second direction L2. A threaded hole penetrating the crimping member 3 is provided at the first end of the crimping member 3. The fastening member 4 extends in the first direction L1. The fastening member 4 is threadedly connected to the threaded hole, and the fastening member 4 abuts against the upper surface of the second positioning member 22 of the positioning member 2. In this way, when the fastening member 4 is tightened, the fastening member 4 rotates relative to the second positioning member 22. Since the fastening member 4 abuts against the upper surface of the second positioning member 22, the first end of the crimping member 3 will move away from the second positioning member 22 relative to the fastening member 4, and the second end of the crimping member 3 moves towards the PCBN grooving tool 1. The second end of the crimping member 3 cooperates with the first positioning surface S1 to realize the positioning of the PCBN grooving tool 1 in the first direction L1.

[0048] Preferably, the fastening member 4 includes a fastening portion 41 and a contact portion 42. The fastening portion 41 abuts against the side of the crimping member 3 facing away from the positioning member 2, and an external thread is formed on the outer sidewall of the contact portion 42. The outer diameter of the fastening portion 41 is larger than that of the contact portion 42, and a pattern is formed on the outer sidewall of the fastening portion 41, which enables an operator to tighten the fastening member 4 by hand-tightening the fastening portion 41, thereby realizing the positioning of the PCBN grooving tool 1.

[0049] Optionally, as Figure 4 and Figure 5 shown, the PCBN grooving tool 1 further includes a third abutting surface S5. The first abutting surface S3 and the third abutting surface S5 are respectively located on both sides of the PCBN grooving tool 1 in the first direction L1. A second positioning groove 12 is formed on the third abutting surface S5, and the second positioning groove 12 extends along the second direction L2. An embedding portion 31 is formed on the side of the second end of the crimping member 3 facing the PCBN grooving tool 1, and the embedding portion 31 can be a strip-shaped structure extending along the second direction L2. In this way, through the cooperation of the embedding portion 31 and the second positioning groove 12, the stability of the contact between the PCBN grooving tool 1 and the crimping member 3 can be ensured, and at the same time, the positioning of the PCBN grooving tool 1 in the third direction L3 can be realized.

[0050] In addition, as Figure 3 and Figure 7 shown, the PCBN grooving tool 1 further includes a mounting member 7. The mounting member 7 is connected to the end of the second positioning member 22 facing away from the second positioning member 22 in the third direction L3. The fixing seat 8 includes a notch 84, a part of the grinding machine extends into the notch 84, and the PCBN grinding fixture is fixed to the grinding machine by a connecting rod 53 passing through the fixing seat 8 and the grinding machine. The fixing seat 8 includes a limiting hole 81 and a connecting groove 82. The limiting hole 81 penetrates the fixing seat 8 along the second direction L2, and the connecting groove 82 is recessed from one side of the fixing seat 8 in the third direction L3 into the fixing seat 8, and the connecting groove 82 communicates with the limiting hole 81; the mounting member 7 is arranged in the limiting hole 81, and the connecting member 6 can apply a force to the fixing seat 8 to make the two parts of the fixing seat 8 on both sides of the connecting groove 82 approach each other in the first direction L1, so as to realize the fixing of the mounting member 7 and the positioning member through the fixing seat 8.

[0051] Preferably, the connecting member 6 can be a bolt.

[0052] Furthermore, a plurality of scale lines 83 are provided on the side of the fixing seat 8 facing away from the second positioning member 22, and the plurality of scale lines 83 are arranged at equal intervals along the circumference of the limiting hole 81; an identification portion 71 is provided on the side of the mounting member 7 facing away from the second positioning member 22, and the mounting member 7 can rotate in the limiting hole 81 so that the identification portion 71 points to a scale line 83. In this way, the inclination of the mounting member 7 and the positioning member 2 connected to the mounting member 7 can be adjusted based on the scale lines 83, thereby adjusting the grinding angle of the PCBN slotting tool 1, so as to meet various complex angle grinding requirements of the PCBN slotting tool 1.

[0053] Optionally, the positioning member 2 encloses a first connecting cavity, and a liquid outlet 211 is provided on the positioning member 2, and the liquid outlet 211 is connected to the first connecting cavity; the mounting member 7 encloses a second connecting cavity, and a liquid inlet 72 is provided on the side of the mounting member 7 facing away from the positioning member 2 in the second direction L2, and the liquid inlet 72 is connected to the second connecting cavity, and the first connecting cavity is connected to the second connecting cavity. In this way, coolant can be provided to the grinding wheel 9 through the liquid inlet 72, the second connecting cavity, the first connecting cavity and the liquid outlet 211. Adding coolant during grinding helps the precision forming of the cutting edge of the PCBN slotting tool 1. The coolant can take away most of the grinding heat and grinding powder, and clean the grinding wheel 9 at the same time.

[0054] When the PCBN slotting tool grinding and positioning device of the present application is used, the first abutting surface S3 of the PCBN slotting tool 1 is abutted against the first positioning surface S1, and the protrusion 23 is placed in the first positioning groove 11 of the PCBN slotting tool 1, and the second abutting surface S4 of the PCBN slotting tool 1 is abutted against the second positioning surface S2, so as to achieve the limitation of the PCBN slotting tool 1 in the first direction L1 and the third direction L3. Then, the fastening member 4 is screwed, so that the second end of the crimping part 3 moves toward the PCBN slotting tool 1, and the embedded part 31 is embedded in the second positioning groove 12. Through the cooperation between the crimping part 3 and the first positioning surface S1, the positioning of the PCBN slotting tool 1 in the second direction L2 can be achieved.
