Description

Technical Field

[0001] This application belongs to the technical field of chamfering equipment, and particularly relates to a chamfering machine. Background Art

[0002] Chamfering refers to the machining of cutting the edges of a workpiece into a certain inclined plane. Chamfering is to remove the burrs generated by machining on the part, and also to facilitate the assembly of the part. Generally, chamfers are made at the ends of the part. During the production and manufacturing process of metal workpieces, a large amount of burrs often remain at the edges of the workpiece or the edges of the holes, and chamfering operations need to be performed on the edges of the workpiece.

[0003] For metal products in the form of pipes, chamfering treatment needs to be carried out on the ends of the pipes. Due to the different sizes and heights of the pipes, the required chamfering positions are also different. Existing chamfering equipment can often only chamfer pipes with fixed sizes. When the pipe size changes, different chamfering equipment needs to be replaced to adapt to the new pipes, which affects the construction continuity and also requires preparing different chamfering equipment for different sizes and models of pipes, and the economy is not good. Utility Model Content

[0007] The chamfering machine described in this application also includes the following additional technical features:

[0008] The first driving module includes a first sliding plate and a first driving cylinder. One of the first sliding plate and the mounting plate is provided with a first guide rail extending along the first movement direction, and the other of the two is provided with a first slider adapted to the first guide rail.

[0011] The chamfering mechanism further includes a fastener. The mounting seat is provided with a plurality of fastening holes along the extending direction of the mounting groove. The fastener passes through the fastening holes and presses the chamfering part against the inner wall of the mounting groove.

[0012] The mounting groove includes an upper mounting groove located at the top of the mounting seat and a lower mounting groove located at the bottom of the mounting seat. The chamfering part is detachably installed in any one of the upper mounting groove and the lower mounting groove.

[0015] The fixing part includes a plurality of fixing plates. The fixing plates have arc-shaped abutting surfaces facing away from the rotating shaft. Each fixing plate is connected to the rotating shaft through a telescopic mechanism. The telescopic mechanism can push the fixing plate to expand outwards so that the arc-shaped abutting surface abuts against the inner wall of the pipe.

[0016] Due to the adoption of the above technical solutions, the beneficial effects obtained by this application are:

[0017] 1. The chamfering machine of the present application includes a fixing mechanism, a chamfering mechanism, and a moving unit. The moving unit can drive the chamfering mechanism to move along a first movement direction and a second movement direction. For pipes with different heights and different diameters, the moving unit can drive the chamfering mechanism to move, so as to adjust the relative position between the chamfering part and the pipe, and thus adjust the chamfering part to a position suitable for chamfering the pipe, improving the adaptability of the chamfering machine to different pipes. Among them, the moving unit includes a mounting plate, a first driving module, and a second driving module. On the one hand, the mounting plate provides a mounting position for the first driving module and the second driving module. On the other hand, the mounting plate can limit the movement direction of the first driving module to a certain extent, so that the first driving module can only move along the first movement direction on the outer surface of the mounting plate, reducing the possibility of the first driving module deviating during movement, helping to improve the alignment accuracy between the chamfering part and the pipe, and thus improving the chamfering accuracy.

[0018] 2. As a preferred embodiment of the present application, by setting a first guide rail and a first slider, the first driving module can only move along the laying direction of the first guide rail, that is, along the first movement direction, avoiding the phenomenon of the first driving module deviating during movement. In addition, on the one hand, the first slider and the first guide rail can cooperate to drive the first driving module to move along the first movement direction. On the other hand, the first driving module is fixed to the mounting plate through the first slider and the first guide rail, eliminating the need for a separate fixing part for the user to fix the first driving module, making the functions of the first slider and the first guide rail further integrated and optimizing the structural design of the moving unit. Moreover, the first driving module realizes movement along the first movement direction by sliding the first slider on the first guide rail, which can improve the smoothness of the movement of the first driving module during movement, reduce the risk of the first driving module getting stuck during movement, and thus help to improve the movement speed of the chamfering part, enabling it to quickly shift to a position suitable for grinding the pipe and improving the continuity of chamfering processing.

[0019] 3. As a preferred embodiment of the present application, by providing the second guide rail and the second slider, the second driving module can only move along the laying direction of the second guide rail, that is, move along the second movement direction, avoiding the phenomenon of movement deviation of the second driving module during the movement process; in addition, on the one hand, the second slider and the second guide rail can cooperate to drive the second driving module to move along the second movement direction, and on the other hand, the second driving module is fixed to the first driving module through the second slider and the second guide rail, eliminating the need for a separate fixing member for the user to fix the second driving module, making the functions of the second slider and the second guide rail further integrated, and optimizing the structural design of the moving unit; furthermore, the second driving module realizes the movement along the second movement direction by sliding the second slider on the second guide rail, which can improve the smoothness of the movement of the second driving module during the movement process and reduce the risk of jamming of the second driving module during the movement process, thereby helping to improve the movement speed of the chamfering part, enabling it to quickly shift to a position suitable for grinding the pipe and improving the continuity of the chamfering process.

[0020] 4. As a preferred embodiment of the present application, the chamfering mechanism includes a mounting seat, the mounting seat has a mounting groove extending towards the fixing mechanism, and the chamfering part is mounted in the mounting groove and can slide along the mounting groove to change the distance from the chamfering mechanism. By providing the mounting groove, a mounting position is provided for the chamfering part, and at the same time, the sliding of the chamfering part in the mounting groove is realized. When the chamfering part approaches the end of the pipe that needs to be chamfered under the drive of the moving unit, the relative position between the chamfering part and the pipe can be finely adjusted by sliding the chamfering part in the mounting groove, thereby improving the chamfering accuracy of the pipe.

[0021] 5. As a preferred embodiment of the present application, the fixing mechanism is set to include a fixing part and a rotating part. The fixing part can be sleeved with the pipe to provide a fixing position for the pipe, and the rotating part can drive the fixing part to rotate so that the pipe sleeved on the fixing part rotates synchronously. During the rotation of the pipe, the chamfering part approaches the end of the pipe to chamfer the pipe. Only relying on the rotation of the pipe can realize the relative movement between the pipe and the chamfering part, thereby realizing the chamfering of the pipe by the chamfering part. During the entire chamfering process, the chamfering mechanism does not move, and the rotation of the pipe with the fixing part also does not occupy extra space, greatly reducing the working space required for the chamfering work and contributing to the miniaturization of the chamfering machine.

[0040] As Figures 1 to 5 shown, a chamfering machine includes a machine body 1, a fixing mechanism 2 and a chamfering mechanism 3 installed on the machine body 1. The fixing mechanism 2 is used to fix a pipe, and the chamfering mechanism 3 is used to chamfer the pipe fixed to the fixing mechanism 2. It further includes a moving unit provided on the machine body 1. The moving unit includes a mounting plate 4, a first driving module 5 installed on the mounting plate 4, and a second driving module 6 installed on the first driving module 5. The chamfering mechanism 3 is installed on the second driving module 6. The first driving module 5 has a first moving direction along the mounting plate 4, the second driving module 6 has a second moving direction along the first driving module 5, and the chamfering mechanism 3 has a chamfering portion 32. The chamfering mechanism 3 changes the relative position between the chamfering portion 32 and the fixing mechanism 2 as the first driving module 5 and the second driving module 6 move.

[0041] The chamfering machine of the present application includes a fixing mechanism 2, a chamfering mechanism 3 and a moving unit. The moving unit can drive the chamfering mechanism 3 to move along a first movement direction and a second movement direction. For pipes with different heights and different diameters, the moving unit can drive the chamfering mechanism 3 to move, adjust the relative position between the chamfering part 32 and the pipe, so as to adjust the chamfering part 32 to a position suitable for chamfering the pipe, improving the adaptability of the chamfering machine to different pipes. Among them, the moving unit includes a mounting plate 4, a first driving module 5 and a second driving module 6. On the one hand, the mounting plate 4 provides a mounting position for the first driving module 5 and the second driving module 6. On the other hand, the mounting plate 4 can limit the movement direction of the first driving module 5 to a certain extent, so that the first driving module 5 can only move along the first movement direction on the outer surface of the mounting plate 4, reducing the possibility of the first driving module 5 deviating during movement, which helps to improve the alignment accuracy between the chamfering part 32 and the pipe, and thus improve the chamfering accuracy.

[0042] Figure 1 The directions of the first movement direction and the second movement direction are schematically shown. The path indicated by the double-headed arrow X is the traveling path of the first movement direction. The first driving module 5 can reciprocate in two directions. The path indicated by the double-headed arrow Z is the traveling path of the second movement direction. The second driving module 6 can reciprocate in two directions. Specifically, the extending directions of the first movement direction and the second movement direction are related to the structural form of the fixing mechanism 2. Figure 1 If the extending direction of the fixing mechanism 2 shown is the vertical direction, then the first movement direction extends along the horizontal direction, and the second movement direction extends along the vertical direction.

[0043] As a preferred embodiment of the present application, as Figure 1 、 Figure 4 、 Figure 5 shown, the first driving module 5 includes a first sliding plate 51 and a first driving cylinder 52. One of the first sliding plate 51 and the mounting plate 4 is provided with a first guide rail 41 extending along the first movement direction, and the other of the two is provided with a first slider 511 adapted to the first guide rail 41. The first sliding plate 51 slides along the first movement direction under the driving action of the first driving cylinder 52 through the cooperation of the first guide rail 41 and the first slider 511.

[0044] Specifically, the first slider 511 is provided with a sliding groove adapted to the shape of the first guide rail 41, and the first slider 511 is clamped and matched with the first guide rail 41 through the sliding groove.

[0045] By setting the first guide rail 41 and the first slider 511, the first driving module 5 can only move along the laying direction of the first guide rail 41, that is, along the first movement direction, avoiding the phenomenon of movement deviation of the first driving module 5 during the movement process; in addition, on the one hand, the first slider 511 and the first guide rail 41 can cooperate to drive the first driving module 5 to move along the first movement direction, and on the other hand, the first driving module 5 is fixed to the mounting plate 4 through the first slider 511 and the first guide rail 41, eliminating the need for a separate fixing member for the user to fix the first driving module 5, further integrating the functions of the first slider 511 and the first guide rail 41, and optimizing the structural design of the moving unit; furthermore, the first driving module 5 realizes the movement along the first movement direction by the sliding of the first slider 511 on the first guide rail 41, which can improve the smoothness of the first driving module 5 during the movement process and reduce the risk of jamming of the first driving module 5 during the movement process, thereby helping to improve the movement speed of the chamfering part 32, enabling it to quickly shift to a position suitable for grinding the pipe, and improving the continuity of the chamfering process.

[0046] As a preferred embodiment of this embodiment, as Figure 1 shown, the second driving module 6 includes a second sliding plate 61 and a second driving cylinder 62. One of the second sliding plate 61 and the first sliding plate 51 is provided with a second guide rail 53 extending along the second movement direction, and the other of the two is provided with a second slider adapted to the second guide rail 53. The second sliding plate 61 slides along the second movement direction under the driving action of the second driving cylinder 62 through the cooperation of the second guide rail 53 and the second slider.

[0047] By setting the second guide rail 53 and the second slider, the second driving module 6 can only move along the laying direction of the second guide rail 53, that is, along the second movement direction, avoiding the phenomenon of movement deviation of the second driving module 6 during the movement process; in addition, on the one hand, the second slider and the second guide rail 53 can cooperate to drive the second driving module to move along the second movement direction, and on the other hand, the second driving module 6 is fixed to the first driving module 5 through the second slider and the second guide rail 53, eliminating the need for a separate fixing member for the user to fix the second driving module 6, further integrating the functions of the second slider and the second guide rail 53, and optimizing the structural design of the moving unit; furthermore, the second driving module 6 realizes the movement along the second movement direction by the sliding of the second slider on the second guide rail 53, which can improve the smoothness of the second driving module 6 during the movement process and reduce the risk of jamming of the second driving module 6 during the movement process, thereby helping to improve the movement speed of the chamfering part 32, enabling it to quickly shift to a position suitable for grinding the pipe, and improving the continuity of the chamfering process.

[0048] As a preferred embodiment of the present application, asFigure 3 As shown, the chamfering mechanism 3 includes a mounting base 31 which has a mounting groove 311 extending towards the fixing mechanism 2. The chamfering part 32 is installed in the mounting groove 311 and can slide along the mounting groove 311 to change the distance from the chamfering mechanism 3. By providing the mounting groove 311, a mounting position is provided for the chamfering part 32, and at the same time, the sliding of the chamfering part 32 in the mounting groove 311 is realized. When the chamfering part 32 approaches the end of the pipe to be chamfered driven by the moving unit, the relative position between the chamfering part 32 and the pipe can be finely adjusted by sliding the chamfering part 32 in the mounting groove 311, thereby improving the chamfering accuracy of the pipe.

[0049] Preferably, the size of the mounting groove 311 is adapted to the size of the chamfering part 32. This enables the chamfering part 32 to move only along the extending direction of the mounting groove 311, preventing the chamfering part 32 from swaying, offsetting, etc. during the sliding process and improving the adjustment accuracy of the chamfering part 32.

[0050] As a preferred embodiment under this preferred implementation manner, as Figure 3 shown, the chamfering mechanism 3 further includes a fastener. The mounting base 31 is provided with a plurality of fastening holes 312 along the extending direction of the mounting groove 311. The fastener passes through the fastening holes 312 and presses the chamfering part 32 against the inner wall of the mounting groove 311. Since the chamfering part 32 will have relatively intense friction with the pipe during the chamfering of the pipe, it may cause the chamfering part 32 to shake. By providing the fastener and the fastening holes 312, the chamfering part 32 can be stably placed in the mounting groove 311 under the pressing action of the fastener, reducing the probability of the chamfering part 32 vibrating or shifting under the action of a severe impact and providing stability guarantee for the chamfering work of the chamfering part 32; in addition, along the extending direction of the mounting groove 311, the number of the fastening holes 312 is set to be multiple. When the chamfering part 32 slides to any position in the mounting groove 311, it is always ensured that at least some of the fastening holes 312 are opposite to the chamfering part 32, and the fastener can pass through these part of the fastening holes 312 to press the chamfering part 32 tightly.

[0051] Preferably, the fastener can be a screw. The inner wall of the fastening hole 312 is provided with threads, and the fastener and the fastening hole 312 screw the chamfering part 32 tightly against the mounting groove 311 by means of threading.

[0052] As another preferred embodiment under this preferred implementation manner, as Figure 3As shown in the figure, the installation groove 311 includes an upper installation groove 3111 located at the top of the installation base 31 and a lower installation groove 3112 located at the bottom of the installation base 31. The chamfering part 32 is detachably installed in any one of the upper installation groove 3111 and the lower installation groove 3112. By providing the upper installation groove 3111 and the lower installation groove 3112, multiple installation positions are provided for the chamfering part 32. The chamfering part 32 can be installed in either the upper installation groove 3111 or the lower installation groove 3112. Limited by the movement stroke of the moving unit, it may occur that the chamfering part 32 cannot be driven to a suitable position within the movement stroke of the moving unit. At this time, the installation position of the chamfering part 32 can be adjusted, and the position of the chamfering part 32 in the upper installation groove 3111 and the lower installation groove 3112 can be adjusted to facilitate the chamfering of the pipe, improving the adaptability of the chamfering machine to pipes of different sizes.

[0053] As a preferred embodiment of the present application, the fixing mechanism 2 includes a fixing part and a rotating part. The fixing part is for the pipe to be sleeved thereon, and the rotating part can drive the fixing part to rotate. The pipe fixed to the fixing part rotates synchronously with the rotation of the fixing part.

[0054] The fixing mechanism 2 is set to include a fixing part and a rotating part. The fixing part can be sleeved with the pipe, providing a fixing position for the pipe. The rotating part can drive the fixing part to rotate, so that the pipe sleeved on the fixing part rotates synchronously. During the rotation of the pipe, the chamfering part 32 approaches the end of the pipe to chamfer the pipe. Only relying on the rotation of the pipe can realize the relative movement between the pipe and the chamfering part 32, so as to realize the chamfering of the pipe by the chamfering part 32. During the whole chamfering process, the chamfering mechanism 3 does not move, and the rotation of the pipe with the fixing part also does not occupy extra space, greatly reducing the working space required for the chamfering work and contributing to the miniaturization of the chamfering machine.

[0055] As a preferred embodiment under this embodiment, as Figure 2As shown, the rotating part includes a rotating motor 22 and a main shaft device connected to the rotating motor 22. The main shaft device includes a rotating shaft 23. The fixing part is installed on the rotating shaft 23 and can expand outwards to abut against the inner wall of the pipe. By providing the main shaft device and the rotating shaft 23, on the one hand, the rotating shaft 23 provides an installation position for the fixing part, enabling the fixing part to be stably placed on the rotating shaft 23. On the other hand, the fixing part can expand outwards and abut against the inner wall of the pipe, locking the pipe on the fixing part through friction, enhancing the connection tightness between the pipe and the fixing part, reducing the probability of the pipe being displaced relative to the fixing part during rotation, and thus ensuring the stability of the relative position between the pipe and the chamfering part 32, which helps to improve the chamfering accuracy. In addition, the way that the fixing part expands from the inside to abut against the pipe makes it unnecessary for the fixing part to occupy the space outside the outer wall of the pipe, reducing the interference of the fixing part on the chamfering part 32 and making the spatial layout of the chamfering machine more reasonable.

[0056] As a preferred example in this embodiment, as Figure 2 shown, the fixing part includes a plurality of fixing plates 21. The fixing plates 21 have arc-shaped abutting surfaces 211 facing away from the rotating shaft 23. Each fixing plate 21 is connected to the rotating shaft 23 through a telescopic mechanism. The telescopic mechanism can push the fixing plate 21 to expand outwards, so that the arc-shaped abutting surface 211 abuts against the inner wall of the pipe. Since the inner wall of the pipe is arc-shaped, by providing the arc-shaped abutting surface 211, the fitting degree between the fixing plate 21 and the pipe can be increased, thereby enhancing the friction between the fixing plate 21 and the pipe and providing guarantee for the stable loading of the pipe on the fixing part.

[0057] Specifically, the telescopic mechanism includes a driving motor and a telescopic arm. The two ends of the telescopic arm are respectively connected to the rotating shaft 23 and the fixing plate 21. The driving motor can drive the telescopic arm to freely expand and contract, thereby driving the fixing plate 21 at its end to approach or move away from the rotating shaft 23, so as to realize the abutting against the inner wall of the pipe.

[0060] The above are only the embodiments of this application and are not used to limit this application. For those skilled in the art, this application can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of this application shall be included within the scope of the claims of this application.
