[0030] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only the parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0031] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0033] In the description of this embodiment, the terms "upper", "lower", "left", "right" and other directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0034] The present embodiment provides a processing structure, which includes a clamp and a tool, wherein one end of the tool is fixed in the clamp. An operator can hold the clamp and use the tool fixed to the clamp to process a groove on the end surface of the workpiece to be processed, so that grooves of various shapes can be processed on the workpiece to be processed, such as a dovetail groove and a V-shaped groove, and the specific shape of the groove is not limited here.

[0035] However, since the diameter of the open end of the dovetail groove gradually decreases, the tool is prone to interfere with the open end of the dovetail groove during the process of machining the dovetail groove, resulting in a decrease in the machining quality of the groove and an inability to ensure the machining quality of the groove.

[0036] In order to solve the above problem, a tool is also provided in this embodiment.

[0037] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0038] like Figure 1 As shown, the tool includes a tool head 10, which includes a cutting member 11 and a connecting member 12. The cutting member 11 is fixedly connected to the first end of the connecting member 12, and the cutting member 11 is used to cut a groove on the end face of the workpiece to be processed; air avoidance structures 121 are respectively arranged on the opposite sides of the connecting member 12, and the air avoidance structures 121 are used to prevent the connecting member 12 from interfering with the open end of the groove during cutting, thereby effectively ensuring the processing quality of the processed groove.

[0039] It should be noted here that in this embodiment, the groove cut on the workpiece is a dovetail groove or a V-shaped groove, and both the dovetail groove and the V-shaped groove can be used for sealing or connecting with other structures. Among them, the dovetail groove presents a notch that is narrow at the top and wide at the bottom, so it is very easy to damage the notch at the upper open end during processing, and the tool avoidance structure 121 provided in this embodiment can effectively solve this problem.

[0040] like Figure 1 As shown, the air avoidance structure 121 is set in an arc shape. If it is designed as a rectangular structure, the right angle of the rectangle will interfere with the open end of the dovetail groove during the groove processing, thereby affecting the processing quality of the groove; and the air avoidance structure 121 is set in an arc shape so that the entire connector 12 can be formed into an arc structure that matches the open end of the groove and has a smooth transition thickness, thereby avoiding the problem that the connector 12 is easily broken during the processing due to the direct setting of the connector 12 as a thinner rectangular structure. Moreover, in this embodiment, the use of the arc-shaped air avoidance structure 121 can also realize the processing of dovetail grooves or V-shaped grooves on the end faces of cylinders with a diameter in the range of 10cm-999cm, expanding the processing range.

[0041] Compared with the prior art, the tool in this embodiment has changed the specific structure of the cutter head 10; by providing arc-shaped air avoidance structures 121 on both sides of the connecting member 12, interference with the open end of the dovetail groove can be effectively prevented. In addition, compared with designing the air avoidance structure 121 as a rectangular structure, setting it in an arc shape is more conducive to increasing the structural strength of the cutter head 10. If it is designed as a rectangle and it is necessary to ensure that the cutter head 10 can effectively prevent interference with the dovetail groove, it is necessary to reduce the thickness of the connecting member 12. At this time, the structural strength of the connecting member 12 will also be greatly reduced, and the cutter head 10 is very easy to break during the processing. Among them, the cutting member 11 is triangular in shape, and the cutting member 11 is protruding in a direction perpendicular to the axis of the cutter head 10.

[0042] It is worth noting that the tool in this embodiment is polished with an arc-shaped air avoidance structure 121, which ensures that the open end of the dovetail groove is not interfered with, while increasing the structural strength of the tool head 10, is simple and efficient, and requires a low level of operation from the operator. As for the process of using this tool to process the groove, it is a conventional method in the art and will not be described in detail in this embodiment.

[0043] At present, since the angles of ordinary dovetail grooves are usually only 24° and 30°, but dovetail grooves with such angles cannot meet various machining requirements, in order to increase the processing angle of the groove and improve the convenience of processing; Figure 1 and Figure 2 As shown, the angle between the blade 111 of the cutting piece 11 and the axis of the cutter head 10 is 45°-48°, so that the cutting angle of the cutting piece 11 is 0°-48°, thereby being able to process a dovetail groove or a V-shaped groove with an angle of 0°-48°. The cutting angle specifically refers to the processing angle of the groove cut by the cutting piece 11.

[0044] It should be noted here that the angle between the blade 111 and the axis of the cutter head 10 is designed to be greater than 45° because the angle between the blade 111 and the axis of the cutter head 10 is greater than the processing angle of the groove to be processed. In this embodiment, the most preferred value of the angle between the blade 111 and the axis of the cutter head 10 is 48°, and the cutting angle is less than or equal to 45°. Therefore, the tool effectively solves the problem that the processing angle of the dovetail groove is too small and cannot meet various mechanical processing requirements, so that the tool has a higher scope of application and versatility.

[0045] The tool also includes a blade body 20, and the second end of the connecting member 12 in the blade head 10 is fixedly connected to the blade body 20. At the same time, in order to facilitate the production of this tool, the blade head 10 and the blade body 20 adopt an integrated structure, and the connection stability between the blade head 10 and the blade body 20 can be ensured. In addition, in order to further ensure the overall strength of the tool, in this embodiment, the entire material from the blade head 10 to the blade body 20 is made of tungsten steel. In other embodiments, materials such as titanium alloy can also be used, as long as the strength and hardness of the tool can be guaranteed to be large enough, and no specific limitation is made in this embodiment.

[0046] In this embodiment, in order to ensure that the entire tool has good structural strength, as Figure 2 and Figure 3 As shown, the total length of the entire tool is 35 cm, the main body of the blade body 20 is cylindrical, and the diameter of the blade body 20 is 5 cm; the distance between the central axis of the blade body 20 and the blade 111 is 1.4 cm; the distance between the blade 111 and the connecting piece 12 close to the blade 111 is 0.9 cm. In other embodiments, the lengths of the blade head 10 and the blade body 20 can also be designed to other values, as long as the overall structural strength of the tool and the convenience of tool processing can be guaranteed, and no other restrictions are made in this embodiment.

[0047] In the prior art, when processing dovetail grooves, most of them are processed by hand sharpening, so the surface flatness of the processed dovetail grooves is poor and extremely rough. Figure 2 As shown, the blade 111 of the cutting member 11 is in an arc shape. With this structure, the resistance generated during cutting is reduced, so that the surface flatness of the groove after cutting is higher. In order to make the blade 111 sharper, the radius of the arc-shaped blade 111 can be designed to be 0.1-0.3 cm. In this embodiment, the most preferred value is 0.2 cm. In other embodiments, the radius of the blade 111 can also be set to other values, as long as the blade 111 can be sharp enough and the surface of the groove after cutting is smooth enough, no other restrictions are made in this embodiment.

[0048] In addition, since the thickness of the connecting member 12 is relatively small, in order to prevent the connection between the connecting member 12 and the blade body 20 from being easily broken, an arc-shaped recessed groove 30 is provided at the connection between the second end of the connecting member 12 and the blade body 20. Since arc-shaped air avoidance structures 121 are provided on both sides of the connecting member 12, the arc-shaped recessed groove 30 can just match the air avoidance structure 121, thereby ensuring that the connection between the cutter head 10 and the blade body 20 is not easy to break, thereby increasing the service life of the tool. At the same time, due to the arc-shaped setting of the arc-shaped recessed groove 30, it is conducive to the discharge of debris generated during the cutting process. If the connection between the cutter head 10 and the blade body 20 is set in a right angle shape, it is not only easy to break, but also easy to accumulate waste chips, which is not conducive to timely chip discharge during the cutting process.

[0049] like Figure 1 As shown, a chip removal arc surface 122 is formed between the air-avoiding structures 121 on opposite sides, one end of the chip removal arc surface 122 is connected to one side of the blade 111, and the other end of the chip removal arc surface 122 extends to the blade body 20. The chip removal arc surface 122 is provided to solve the problem of difficult chip removal during the groove processing process. At the same time, the chip removal arc surface 122 has a simple structure and also plays a role in beautiful appearance.

[0050] What needs to be explained here is that Figure 2 and Figure 3 As shown, a first bevel 21 is provided at one end of the blade body 20 that is not connected to the cutter head 10, and a second bevel matching the first bevel 21 is provided in the clamping member of the processing structure; when the blade body 20 is fixed in the clamping member, the first bevel 21 can be guided and fitted with the second bevel to form a matching structure; that is, when the tool is fixed to the clamping member, the first bevel 21 and the second bevel can play a guiding role, so as to facilitate the rapid clamping between the tool and the clamping member, so that the clamping efficiency is high. In addition, in order to ensure the structural strength of the fitting between the first bevel 21 and the second bevel, in the direction perpendicular to the axis of the cutter head 10, the first bevel 21 does not penetrate the entire blade body 20, so as to reduce the fitting area between the first bevel 21 and the second bevel, so that the blade body 20 can provide a certain structural strength for the fitting between the first bevel 21 and the second bevel.

[0051] When using the tool provided by the utility model, first extend one end of the tool with the first inclined surface 21 into the clamping member, so that the one end of the tool can be quickly installed into the clamping member through the guiding effect between the first inclined surface 21 and the second inclined surface, and the tool and the clamping member are clamped and fixed; then the operator can perform groove processing by holding the clamping member, so that the surface of the workpiece to be processed can be cut into a dovetail groove or a V-shaped groove by the blade 111 of the cutter head 10. If there is no suitable clamping member to fix the tool, the operator can also directly cut the dovetail groove or the V-shaped groove by holding the blade body 20.

[0052] In summary, when using the tool provided by the utility model, it can be ensured that the tool is not easy to interfere with the open end of the dovetail groove during the cutting process, and good processing quality and extremely high work efficiency of the groove can be guaranteed.

[0053] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention.
