Description

Technical Field

[0001] The utility model relates to the technical field of machine tools, in particular to a supporting device and a machine tool having the same. Background Art

[0002] At present, when operating a boring machine to perform boring processing, a boring sleeve is usually used to support the boring bar to ensure that the boring bar has a high processing accuracy.

[0003] In the prior art, one of the most common types of boring sleeves is the external roller boring sleeve. The innermost sleeve of the external roller boring sleeve can rotate synchronously with the boring bar. The innermost sleeve is provided with a guide groove and a tool groove. The guide groove cooperates with the guide key on the boring bar, and the tool groove is used to avoid the tool on the boring bar. When the staff assembles the boring sleeve and the boring bar, it is necessary to adjust the rotation angle of the innermost sleeve of the boring sleeve to ensure that the guide groove is aligned with the guide key on the boring bar and the tool groove is aligned with the tool on the boring bar, thereby avoiding collision between the two during assembly.

[0004] However, since the innermost sleeve of the outer roller boring sleeve can rotate, after the staff adjusts the rotation angle of the boring sleeve, the boring sleeve may still rotate due to the vibration of the machine tool or other reasons, which may cause the boring bar to collide with the boring sleeve during the assembly process, seriously affecting the service life of the boring bar and the boring sleeve.

The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0027] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0029] In order to solve the problem of easy accidental collision between the boring bar and the boring sleeve of the boring machine in the prior art, the present application provides a supporting device and a machine tool having the same.

[0030] like Figures 1 to 3 As shown, the support device includes an outer ring structure 10, an inner ring structure 20 and a stopper 40. The inner ring structure 20 is rotatably arranged in the outer ring structure 10. A through hole 23 is arranged on the inner ring structure 20. The through hole 23 extends along the radial direction of the inner ring structure 20. The inner hole of the inner ring structure 20 is used for the installation rod of the tool assembly to pass through. The inner ring structure 20 and the installation rod are in a stop-rotation cooperation to support the installation rod. The stopper 40 is telescopically arranged in the through hole 23 and the inner ring structure 20 is in a stop-rotation cooperation. The stopper 40 has a stopper position and a follow-up position. When the stopper 40 is in the stopper position, the stopper 40 stops the inner ring structure 20 by limiting the position with at least part of the outer ring structure 10; when the stopper 40 is in the follow-up position, the stopper 40 is separated from the outer ring structure 10 and rotates synchronously with the inner ring structure 20.

[0031] According to the technical solution of this embodiment, the inner ring structure 20 of the support device is rotatably arranged in the outer ring structure 10, and a through hole 23 is arranged on the inner ring structure 20, and the through hole 23 extends along the radial direction of the inner ring structure 20. The inner hole of the inner ring structure 20 is used for the installation rod of the tool assembly to pass through, and the inner ring structure 20 is matched with the installation rod to stop rotation, so as to support the installation rod, and the stopper 40 is telescopically arranged in the through hole 23 and is matched with the inner ring structure 20 to stop rotation. Among them, the stopper 40 has a stop position and a follow-up position. When the stopper 40 is in the stop position, the stopper 40 stops the inner ring structure 20 by limiting the position with at least part of the outer ring structure 10; when the stopper 40 is in the follow-up position, the stopper 40 is separated from the outer ring structure and rotates synchronously with the inner ring structure 20. In this way, after the staff adjusts the rotation angle of the inner ring structure 20 to a suitable position, the staff can operate the stopper 40 to move to the stop position to stop the inner ring structure 20, thereby preventing the inner ring structure 20 from continuing to rotate due to other reasons such as machine tool vibration, causing the installation rod to accidentally collide with the inner ring structure 20 during the installation process, thereby affecting the service life of the support device and the installation rod, thereby solving the problem of easy accidental collision between the boring rod and the boring sleeve of the boring machine in the prior art. At the same time, after the installation rod is inserted into the inner hole of the inner ring structure 20, the staff can also operate the stopper 40 to move from the stop position to the follow-up position, so that the stopper can rotate synchronously with the inner ring structure 20, thereby ensuring that the support device can normally support the tool assembly.

[0032] In this embodiment, the supporting device is a boring sleeve of a boring machine, and the mounting rod is a boring bar of the boring machine.

[0033] In this embodiment, a keyway and a tool groove are further provided on the inner wall of the inner ring structure 20. The keyway is used to cooperate with the guide key of the boring bar, and the tool groove is used to avoid the tool on the boring bar. When the staff operates the inner ring structure 20 to rotate to a suitable angle, the keyway on the inner ring structure 20 can be opposite to the guide key on the boring bar, and the tool groove can be opposite to the tool on the boring bar.

[0034] In this embodiment, an installation space 30 is formed between the outer ring structure 10 and the inner ring structure 20. A bearing is also arranged in the installation space 30. The bearing is used to realize the relative rotation between the inner ring structure 20 and the outer ring structure 10 and to support the inner ring structure 20 to ensure that the inner ring structure 20 has high rotation stability.

[0035] In this embodiment, the function of the support device can be realized by only processing the original boring sleeve. Specifically, only one additional through hole 23 needs to be processed on the inner ring structure 20 to install the anti-rotation member 40 and realize the anti-rotation function of the anti-rotation member 40, which not only makes the inner ring structure 20 have less material removed, but also reduces the thermal deformation and stress caused by processing, and also makes the above processing have little effect on the inner hole accuracy of the inner ring structure 20.

[0036] like Figure 1 and Figure 2 As shown, the penetration hole 23 is also connected to the inner hole of the inner ring structure 20. When the stopper 40 is in the stop position, at least part of the stopper 40 is located in the inner hole of the inner ring structure 20. When the mounting rod is penetrated into the inner hole of the inner ring structure 20, the mounting rod abuts against at least part of the stopper 40 to push the stopper 40 to move from the stop position to the follow-up position. In this way, when the boring machine passes the mounting rod into the inner hole of the inner ring structure 20, the mounting rod can spontaneously push the anti-rotation member 40 to move from the anti-rotation position to the follow-up position, so as to ensure that the inner ring structure 20 can rotate synchronously with the mounting rod after the mounting rod is installed. On the one hand, the staff does not need to operate the anti-rotation member 40 to move to the follow-up position, thereby reducing the labor intensity of the staff and improving the automation degree of the boring machine; on the other hand, it can prevent the staff from forgetting to operate, which will cause interference between the inner ring structure 20 and the mounting rod, and then cause damage to the inner ring structure 20 and the mounting rod, thereby improving the operating stability of the boring machine and extending the service life of the support device and the mounting rod.

[0037] In this embodiment, one end of the penetration hole 23 close to the inner hole of the inner ring structure 20 is arranged in the keyway of the inner ring structure 20. In this way, during the penetration process of the mounting rod, the guide key on the mounting rod can extend into the keyway and press against the anti-rotation member 40, thereby improving the matching reliability between the mounting rod and the anti-rotation member 40.

[0038] like Figure 1 and Figure 2As shown, the inner ring structure 20 includes an inner ring body 21 and a mounting structure 22, and a through hole 23 is provided on the inner ring body 21. The mounting structure 22 is provided on the surface of the inner ring body 21 facing the outer ring structure 10. The support device further includes a reset structure 50, and the two ends of the reset structure 50 are respectively connected to the stop member 40 and the mounting structure 22, so as to apply a reset force to the stop member 40 to move toward the stop position. In this way, after the mounting rod is withdrawn from the inner hole of the inner ring structure 20, the staff only needs to rotate the inner ring structure 20 to a suitable angle, and the stop member 40 can be automatically reset under the action of the reset force of the reset structure 50, so that the staff does not need to manually operate the stop member 40 to reset to the stop position, thereby reducing the operating difficulty and labor intensity of the staff. At the same time, since the mounting structure 22 is arranged on the inner ring body 21, the mounting structure 22 can rotate along with the inner ring body 21, that is, the mounting structure 22 and the stop member 40 rotate synchronously, so that the two ends of the reset structure 50 have no relative position, thereby avoiding friction and deformation between the reset structure 50 and the mounting structure 22 or the stop member 40, thereby extending the service life of the reset structure 50.

[0039] Optionally, the reset structure 50 is a spring.

[0040] In this embodiment, the mounting structure 22 is actually an outer spacer of the boring sleeve, which is used to separate the bearings arranged in the mounting space 30. That is, the support device uses the original outer spacer to realize the installation of the reset structure 50, which not only makes the structure of the support device simpler, but also reduces the processing cost of the support device and the processing difficulty of the staff.

[0041] In this embodiment, the mounting structure 22 is arranged in an annular shape and includes a third annular plate body 221 and a fourth annular plate body 222. One end of the third annular plate body 221 is connected to the outer peripheral surface of the inner ring body 21, and the fourth annular plate body 222 is arranged on the other end of the third annular plate body 221. The third annular plate body 221 and the fourth annular plate body 222 are arranged at a first angle. In this way, the above arrangement enables the shape of the mounting structure 22 to match the shape of the outer ring structure 10 on the one hand; on the other hand, the structure of the mounting structure 22 is simpler, easier to process and realize, thereby reducing the processing degree of the mounting structure 22 and the processing difficulty of the staff.

[0042] In this embodiment, the third annular plate body 221 and the fourth annular plate body 222 are arranged at 90 degrees.

[0043] In this embodiment, one end of the reset structure 50 away from the rotation-stopping member 40 is connected to the fourth annular plate body 222 .

[0044] like Figure 1 and Figure 2As shown, the stopper 40 is provided with a receiving recess 43, and one end of the reset structure 50 away from the mounting structure 22 extends into the receiving recess 43 and is connected to the bottom wall of the receiving recess 43. In this way, the receiving recess 43 can fix and limit the reset structure 50, so as to prevent the reset structure 50 from being separated from the stopper 40 or the mounting structure 22, thereby preventing the reset function of the reset structure 50 from failing, thereby improving the reset reliability of the reset structure 50.

[0045] like Figure 1 and Figure 2 As shown, the outer ring structure 10 has a first matching portion, the anti-rotation member 40 has a second matching portion, one of the first matching portion and the second matching portion is a protrusion, and the other of the first matching portion and the second matching portion is a recess. When the anti-rotation member 40 is in the anti-rotation position, the protrusion extends into the recess and engages with the recess. In this way, the above-mentioned setting, on the one hand, improves the reliability of the limit stop between the anti-rotation member 40 and the outer ring structure 10 through the engagement between the first matching portion and the second matching portion, thereby improving the anti-rotation reliability of the anti-rotation member 40; on the other hand, the structure of the first matching portion and the second matching portion is made more flexible and diverse to adapt to different working conditions and usage requirements, and also improves the processing flexibility of the staff.

[0046] In this embodiment, the first matching portion is a recessed portion, and the second matching portion is a protrusion.

[0047] In other embodiments shown in the accompanying drawings, the first matching portion is a protrusion, and the second matching portion is a recess.

[0048] like Figures 1 to 3 As shown, the outer ring structure 10 includes an outer ring body 11 and a stopper structure 12, and the first matching portion is arranged on the stopper structure 12, and the stopper structure 12 is arranged on the surface of the outer ring body 11 facing the inner ring structure 20. Among them, the stopper structure 12 has an annular guide channel 123, and when the stopper 40 is in the follower position, at least part of the stopper 40 is located in the annular guide channel 123, and the annular guide channel 123 is used to guide the movement direction of the stopper 40. In this way, by arranging the first matching portion on the stopper structure 12, it is ensured that the first matching portion can match with the second matching portion on the stopper 40, thereby improving the matching reliability between the first matching portion and the second matching portion. At the same time, by arranging the annular guide channel 123 to guide the movement direction of the stopper 40, the movement stability of the stopper 40 can be improved, so as to avoid the interference between the stopper 40 and the outer ring structure 10 that rotate synchronously with the inner ring structure 20, thereby affecting the rotation stability of the inner ring structure 20, thereby improving the operation stability of the support device.

[0049] In this embodiment, the stop structure 12 is actually an inner spacer sleeve of the boring sleeve, and the inner spacer sleeve is used to separate the bearings installed in the installation space 30. That is, the present application improves the original inner spacer sleeve in the boring sleeve to achieve the coordination between it and the stop member 40, thereby achieving a simpler structure of the support device, which is easier to process and realize, and also reduces the processing difficulty of the staff and the processing cost of the support device.

[0050] like Figures 1 to 3 As shown, the first matching portion is a recessed portion, which is a notch 1221. The stopper structure 12 includes a connecting portion 121 and a stopper body 122. The stopper body 122 is connected to the inner wall of the outer ring body 11 through the connecting portion 121. An annular guide channel 123 is formed around the stopper body 122 and the connecting portion 121. The notch 1221 is connected to the annular guide channel 123. When the stopper 40 is in the stop position, at least part of the stopper 40 is located in the notch 1221 and is limited and stopped by the inner wall of the notch 1221. When the stopper 40 moves from the stop position to the follow-up position, the part of the stopper 40 used for limiting and stopping with the inner wall of the notch 1221 passes through the notch 1221 and moves into the annular guide channel 123. In this way, on the one hand, the above-mentioned arrangement makes the formation of the annular guide channel 123 simpler, easier to process and realize; on the other hand, since the recess is a notch 1221 connected to the annular guide channel 123, the stop member 40 can spontaneously move into the annular guide channel 123 through the notch 1221 or escape from the annular guide channel 123 through the notch 1221 during the switching process between the stop position and the follow-up position, thereby achieving a more compact and reasonable structure of the stop structure 12.

[0051] In this embodiment, the connecting portion 121 is arranged in an annular shape and includes a first annular plate body 1211 and a second annular plate body 1212 that are connected to each other. The plate surface of the first annular plate body 1211 away from the second annular plate body 1212 is connected to the inner wall of the outer ring body 11. The second annular plate body 1212 and the first annular plate body 1211 are arranged at a second angle. The stop body 122 is annular and is arranged on the second annular plate body 1212. The stop body 122 is arranged opposite to at least part of the first annular plate body 1211 so that an annular guide channel 123 is formed between the stop body 122, the first annular plate body 1211 and the second annular plate body 1212.

[0052] In this embodiment, the second annular plate body 1212 and the first annular plate body 1211 are arranged at 90 degrees.

[0053] like Figure 1 and Figure 2As shown, the second matching portion is a protrusion, and the stopper 40 includes a columnar penetration portion 41 and a block-shaped stopper 42. The columnar penetration portion 41 can be telescopically penetrated in the penetration hole 23, and the block-shaped stopper 42 is arranged on one end of the columnar penetration portion 41 close to the outer ring structure 10. The length of the block-shaped stopper 42 is greater than the diameter of the columnar penetration portion 41, so that at least part of the block-shaped stopper 42 forms a protrusion. Among them, a guide slope 411 is arranged on one end of the columnar penetration portion 41 away from the block-shaped stopper 42. The guide slope 411 is used to abut against the installation rod. During the penetration process of the installation rod, the installation rod moves along the guide slope 411 to push the stopper 40 from the stop position to the follow-up position. In this way, on the one hand, the above-mentioned arrangement makes the formation of the protrusion simpler and easier to process, thereby reducing the processing degree of the anti-rotation part 40 and the processing difficulty of the staff; on the other hand, it enables the mounting rod to cooperate with the guide bevel 411 on the columnar penetration part 41, thereby improving the reliability of the mounting rod pushing the anti-rotation part 40.

[0054] like Figure 1 and Figure 2 As shown, the support device further includes a sealing member 60, which is sleeved on the stop member 40, and the sealing member 60 is used to seal at least part of the gap between the stop member 40 and the hole wall of the through hole 23. In this way, by providing the sealing member 60 to seal the gap between the stop member 40 and the hole wall of the through hole 23, it is possible to prevent impurities such as cutting materials and cutting fluid from flowing into the support device through the gap during the operation of the boring machine, thereby preventing the support device from being damaged, thereby extending the service life of the support device.

[0055] Optionally, the sealing member 60 is a Y-shaped sealing ring.

[0056] The present application also provides a machine tool (not shown), which includes a machine tool body, a tool assembly and a support device, wherein the support device is arranged on the machine tool body to support the mounting rod of the tool assembly.

[0057] From the above description, it can be seen that the above embodiments of the utility model achieve the following technical effects:

[0058] The inner ring structure of the support device is rotatably arranged in the outer ring structure, and a through hole is arranged on the inner ring structure, and the through hole extends along the radial direction of the inner ring structure. The inner hole of the inner ring structure is used for the installation rod of the tool assembly to pass through, and the inner ring structure and the installation rod are matched to stop rotation, so as to support the installation rod, and the stopper is telescopically arranged in the through hole and the inner ring structure is matched to stop rotation. Among them, the stopper has a stop position and a follow-up position. When the stopper is in the stop position, the stopper stops the inner ring structure by limiting the position with at least part of the outer ring structure; when the stopper is in the follow-up position, the stopper is separated from the outer ring structure and rotates synchronously with the inner ring structure. In this way, after the staff adjusts the rotation angle of the inner ring structure to a suitable position, the staff can operate the stopper to move to the stop position to stop the inner ring structure, thereby preventing the inner ring structure from continuing to rotate due to other reasons such as machine tool vibration, causing the installation rod to accidentally collide with the inner ring structure during the installation process, thereby affecting the service life of the support device and the installation rod, thereby solving the problem of easy accidental collision between the boring bar and the boring sleeve of the boring machine in the prior art. At the same time, after the installation rod is inserted into the inner hole of the inner ring structure, the staff can also operate the stopper to move from the stop position to the follow-up position, so that the stopper can rotate synchronously with the inner ring structure, thereby ensuring that the support device can normally support the tool assembly.
