Description

Technical Field

[0001] This utility model belongs to the field of track processing technology, specifically relating to a track integral forming tool. Background Technology

[0002] Orbit forming tools are tools used to machine orbit forming surfaces. Existing orbit forming tools are simple cylindrical or flat in shape, with a relatively conventional and simple structure. They lack fine partitioning and angle design and can only perform straight line machining. When machining special geometric shapes, multiple tool passes and alignment adjustments of the tool pass angle are required, resulting in complex machining processes and procedures.

[0003] Furthermore, existing track forming tools lack precise partitioning and angle design, making it impossible to accurately grind and process the angles and dimensions of the track. This results in low processing efficiency, large processing errors, and surface roughness that does not meet requirements, failing to guarantee the processing quality and surface accuracy of the track, and also affecting the track's performance. Utility Model Content

[0004] To address the problems of conventional and simple track forming tool structures in the existing technology, which require multiple tool passes, alignment and adjustment of tool pass angles, complex processing technology and low processing efficiency when machining special geometries, this utility model provides an integrated track forming tool.

[0005] The technical effects to be achieved by this utility model are realized through the following technical aspects:

[0006] This utility model provides an integrated track forming tool, comprising: a cylindrical tool body; a plurality of evenly distributed drainage grooves arranged around the circumference of the tool body on its outer side wall; the drainage grooves having identical structures and penetrating the upper and lower surfaces of the tool body; the drainage grooves dividing the tool body into an equal number of cutting edge groups; and a forming groove arranged around the circumference of the tool body on its outer side wall, the forming groove communicating with the drainage grooves to divide the cutting edge groups into upper and lower cutting edges. By using the plurality of evenly distributed drainage grooves arranged around the circumference of the tool body to divide the tool body into an equal number of cutting edge groups, and by using the forming groove arranged around the circumference of the tool body and communicating with the drainage grooves to divide the cutting edge groups into upper and lower cutting edges, the shape of the forming groove matches the shape of the track to be processed, thereby achieving one-time processing of both sides of the track, optimizing the forming process, and improving forming efficiency and quality.

[0007] In some optional implementations, the front side of the cutting edge assembly is straight along the rotation direction of the tool body, and an acute angle is formed between the front side of the cutting edge assembly and the outer side wall of the tool body. The acute angle design at the contact end of the cutting edge assembly with the guide rail forming surface makes the cutting edge sharper during cutting, reduces cutting resistance, and improves cutting efficiency. Simultaneously, during the rotation of the tool body, the several cutting edge assemblies are rotationally symmetrical, ensuring the stability and consistency of the tool body during rotational cutting.

[0008] In some optional implementations, the tool body rotates symmetrically with respect to several cutting edge groups during rotation. This ensures the stability and consistency of the tool body during rotary cutting.

[0009] In some optional implementations, the number of drainage grooves is at least three. The drainage grooves have the same structure and penetrate through the upper and lower surfaces of the tool body, which facilitates the timely discharge of chips from the tool body during machining, preventing chips from accumulating between the tool body and the guide rail, thus affecting machining accuracy and the service life of the tool body.

[0010] In some alternative implementations, the number of drainage grooves is set to four, and the four cutting edge groups are arranged in a centrally symmetrical structure. This centrally symmetrical structure of the four cutting edge groups helps to improve the cutting stability and uniformity of the tool body.

[0011] In some optional implementations, the forming groove is V-shaped; the angle between the upper and lower walls of the forming groove is set to 65°-75°. The V-shape of the forming groove facilitates the precise machining of components such as the side guide structure of the track during the machining process, in conjunction with the cutting edge assembly.

[0012] In some alternative implementations, the upper wall surface and the lower wall surface of the forming groove are symmetrically arranged along the central axis of the forming groove to ensure the symmetry and accuracy of the processed track structure.

[0013] In some alternative implementations, a cross-section is made perpendicular to the travel direction of the tool body, and the cross-sectional shape of the forming groove matches the cross-sectional shape of the side guide structure of the track. This ensures that the tool can accurately machine the required track structure.

[0014] In some alternative implementations, a tool holder is also included, which is cylindrical and disposed on the end face of the tool body and coaxially arranged with the tool body.

[0015] In some optional implementations, the connection end face between the tool body and the tool holder is either flat or curved. The shape design of the connection end face between the tool body and the tool holder can be selected according to different processing requirements and equipment requirements to ensure the connection strength and stability between the tool body and the tool holder.

[0016] In summary, this utility model has at least the following advantages:

[0017] This utility model provides an integrated track forming tool. By providing several evenly distributed drainage grooves around the outer side wall of the tool body, the tool body is divided into an equal number of cutting edge groups. By providing a forming groove along the outer side wall of the tool body that communicates with the drainage grooves, the cutting edge groups are divided into upper and lower cutting edges. The shape of the forming groove matches the shape of the track to be processed, thereby realizing the one-time processing and forming of both sides of the track, optimizing the forming process, and improving forming efficiency and forming quality.

[0042] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are some, but not all, of the embodiments of this utility model.

[0043] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0044] To address the problems of conventional and simple track forming tool structures in the prior art, which require multiple tool passes, alignment and adjustment of tool pass angles, complex processing technology, and low processing efficiency when machining special geometric shapes, this utility model provides an integrated track forming tool.

[0045] This utility model provides an integrated track forming tool, such as... Figure 1 As shown, it includes: a cylindrical tool body 10, with a plurality of evenly distributed drainage grooves 11 on the outer side wall of the tool body 10 around the circumference of the tool body 10. The plurality of drainage grooves 11 have the same structure and penetrate the upper and lower surfaces of the tool body 10. The plurality of drainage grooves 11 divide the tool body 10 into the same number of cutting edge groups 13. A forming groove 12 is provided on the outer side wall of the tool body 10 around the circumference of the tool body 10. The forming groove 12 communicates with the drainage grooves 11 to divide the cutting edge group 13 into an upper cutting edge 131 and a lower cutting edge 132.

[0046] In this embodiment, the tool body 10 is divided into an equal number of blade groups 13 by a plurality of evenly distributed drainage grooves 11 arranged around the outer side wall of the tool body 10. The blade group 13 is divided into an upper blade 131 and a lower blade 132 by a forming groove 12 arranged around the outer side wall of the tool body 10 and communicating with the drainage grooves 11. The shape of the forming groove 12 matches the shape that the track needs to be processed. The upper blade 131 and the lower blade 132 process and form both sides of the track at one time, which optimizes the forming process and improves forming efficiency and forming quality.

[0047] In this embodiment, a plurality of evenly distributed discharge grooves 11 are provided around the outer side wall of the tool body 10. The plurality of discharge grooves 11 have the same structure and penetrate the upper and lower surfaces of the tool body 10. The plurality of discharge grooves 11 can discharge chips in a timely manner during the machining process of the tool body 10, avoiding the accumulation of chips between the tool body 10 and the track, which would affect the machining accuracy and tool life.

[0048] In this preferred embodiment, the number of drainage grooves 11 is set to at least three. Therefore, the number of blade groups 13 is also set to at least three. The three drainage grooves 11 are rotationally symmetrical, which means that the three blade groups 13 are rotationally symmetrical.

[0049] Preferably, the number of drainage grooves 11 is set to four, and the number of cutting edge groups 13 is also set to four. The four cutting edge groups 13 are centrally symmetrical, which helps to improve the cutting stability and uniformity of the tool.

[0050] By using a forming groove 12 arranged circumferentially on the outer side wall of the tool body 10, which communicates with the drainage groove 11, the cutting edge assembly 13 is divided into an upper cutting edge 131 and a lower cutting edge 132. This allows the upper cutting edge 131 and the lower cutting edge 132 to precisely machine components such as the side guide structure of the track in one go during the machining process of the tool body 10, optimizing the forming process and improving forming efficiency and quality.

[0051] The shape of the forming groove 12 matches the side guide structure and other components of the track that need to be machined.

[0052] This embodiment is a preferred embodiment, such as... Figure 2 As shown, the forming groove 12 is V-shaped; the shape design of the forming groove 12 can be used in conjunction with the cutting edge assembly 13 to accurately process components such as the side guide structure of the track during the machining process of the tool body 10.

[0053] In some optional embodiments, the included angle α between the upper wall surface 121 and the lower wall surface 122 of the forming groove 12 is set to 65°-75°.

[0054] Preferably, the included angle α between the upper wall surface 121 and the lower wall surface 122 of the forming groove 12 is set to 70°, so as to realize the processing of the side guide structure of the track with a fixed angle.

[0055] The upper wall 121 of the forming groove 12 is the lower surface of the upper blade 131, and the lower wall 122 of the forming groove 12 is the upper surface of the lower blade 132. Therefore, the included angle α between the upper wall 121 and the lower wall 122 of the forming groove 12 can also be understood as the included angle between the lower surface of the upper blade 131 and the upper surface of the lower blade 132.

[0056] The included angle α between the upper wall 121 and the lower wall 122 of the forming groove 12 can be adjusted according to actual processing requirements.

[0057] Furthermore, the upper wall 121 and lower wall 122 of the forming groove 12 are symmetrically arranged along the central axis of the forming groove 12 to ensure the symmetry and accuracy of the side guide structure of the processed track.

[0058] In addition, in this embodiment, the diameter of the tool body 10 is set to 20mm-50mm, for example, it can be set to 20mm, 25mm, 30mm, 35mm, 40mm, 45mm, 50mm, etc., and the depth of the forming groove 12 along the diameter direction of the tool body 10 is less than the radius of the tool body 10.

[0059] The diameter setting parameters of the tool body 10, the depth design parameters of the forming groove 12, and the angle design parameters of the forming groove 12 can be adjusted and optimized according to the size of the side guide structure 31 of the track 30 to be processed. This embodiment does not explicitly limit them.

[0060] In this embodiment, the specific shape of the blade assembly 13 has been optimized.

[0061] like Figure 3 As shown, along the rotation direction of the tool body 10, the front side 111 of the cutting edge assembly 13 is straight, and the front side 111 of the cutting edge assembly 13 and the outer side wall 101 of the tool body 10 are set at an acute angle.

[0062] The contact end of the cutting edge assembly 13 with the guide rail forming surface adopts an acute angle design, which makes the cutting edge sharper during cutting, reduces cutting resistance, and improves cutting efficiency. At the same time, during the rotation of the tool body 10, the several cutting edge assemblies 13 are rotationally symmetrical, ensuring the stability and consistency of the tool during the rotational cutting process.

[0063] In this embodiment, the track-integrated forming tool rotates clockwise. In actual use, as... Figure 4-6 As shown, the guide structure 31 on the left side of the track 30 is processed and shaped.

[0064] Specifically, a cross-section is made in a direction perpendicular to the travel direction of the tool body 10, and the cross-sectional shape of the forming groove 12 matches the cross-sectional shape of the side guide structure 31 of the track 30, thereby ensuring that the tool can accurately machine the track structure that meets the requirements.

[0065] In some alternative embodiments, the orbital integrally formed tool, such as Figure 7-9 As shown, it rotates counterclockwise. In actual use, as... Figure 10-12 As shown, the guide structure 31 on the right side of the track 30 is processed and shaped.

[0066] In this preferred embodiment, the integrated track cutting tool also includes a tool holder 20, which is cylindrical and is disposed on the end face of the tool body 10 and coaxially arranged with the tool body 10.

[0067] In this embodiment, the tool holder 20 is cylindrical and is disposed on the end face of the tool body 10 and coaxially arranged with the tool body 10, facilitating connection with the spindle of the machining equipment to realize the rotational movement of the tool. The tool body 10 is also cylindrical and is the key part of the tool for cutting.

[0068] In this preferred embodiment, the connecting end face of the tool body 10 and the tool holder 20 is either flat or curved.

[0069] In this embodiment, the connection end face between the tool body 10 and the tool holder 20 is designed to be either flat or curved, so that it can be selected according to different processing needs and equipment requirements, thereby ensuring the connection strength and stability between the tool body 10 and the tool holder 20.

[0070] In this embodiment, the tool holder 20 is mounted on the spindle of the machining equipment, ensuring a firm connection between the tool holder 20 and the spindle, and that the coaxiality meets the requirements. Based on the specific requirements of machining the track 30, a suitable tool body 10 is selected to connect with the tool holder 20; a planar or arc-shaped connection end face can be chosen according to the actual situation.

[0071] In this embodiment, the diameter of the tool holder 20 can also be adjusted according to the diameter of the tool body 10 and the depth of the forming groove 12.

[0072] Preferably, the diameter of the shank 20 is less than or equal to the radius of the tool body 10.

[0073] Alternatively, the diameter of the shank 20 may be less than or equal to the difference between the diameter of the tool body 10 and twice the depth of the forming groove 12.

[0074] Preferably, the diameter of the tool holder 20 can also be adjusted according to the connection structure with the processing equipment, and optimized with the connection strength and stability with the processing equipment as a reference standard.

[0075] In this embodiment, the diameter design parameters of the tool holder 20, the diameter design parameters of the tool body 10, the depth design parameters of the forming groove 12, and the angle design parameters of the forming groove 12 can all be adjusted and optimized according to the shape of the side guide structure 31 of the track 30 to be processed. This embodiment does not impose any explicit limitations on this.
