Description

Technical Field

[0001] The utility model relates to the technical field related to boring and milling machine clamps, in particular to a tool-changing auxiliary support mechanism for a numerically controlled boring and milling machine clamp. Background Art

[0002] In modern manufacturing, the application of CNC machining equipment is becoming more and more common. They can process with higher precision, faster speed and stronger flexibility, greatly improving production efficiency and product quality. CNC boring and milling machines, as important equipment, play a vital role in parts processing. However, traditional CNC boring and milling machines have some shortcomings in the clamp tool changing process, which has given rise to the development of clamp tool changing auxiliary support mechanism. On CNC boring and milling machines and other machine tools, clamp tool changing is a common operation step, but the traditional tool changing process usually requires operators to make manual adjustments, which is not only time-consuming and labor-intensive, but also poses safety risks.

[0003] In the automatic tool changing device of a CNC boring and milling machine, it is necessary to transfer and load and unload tools between the tool magazine and the boring and milling machine spindle. In the prior art, a manipulator is used, which has a clamping part. When changing tools, the used tool needs to be put back into the tool magazine, and then a new tool is taken out from the tool magazine and installed on the boring and milling machine spindle of the boring and milling machine.

[0004] The shapes of tools currently on the market are different, and the fixture of the automatic tool changing device of the existing CNC boring and milling machine cannot be replaced. Therefore, when facing different tools, the clamping effect of the fixture on each tool is different, and the clamping effect on some tools is poor. Utility Model Content

[0005] Based on this, the purpose of the utility model is to provide a CNC boring and milling machine clamp tool changing auxiliary support mechanism to solve the technical problem that the traditional device has poor clamping effect on some tools.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a CNC boring and milling machine clamp tool changing auxiliary support mechanism, including a driving device and a lathe, the output end of the driving device is connected to a connecting arm, and the upper and lower ends of the movable end of the connecting arm are connected to a clamp, a first limit block is arranged between the inside of the clamp, and two first limit blocks are provided with a clamping groove at one end toward the middle, each of the clamping grooves is connected to a rotating shaft on both sides toward the middle end, and each outer wall of the rotating shaft is rotatably sleeved with a clamp, every two of the clamps in the same horizontal plane cooperate with each other, and the two groups of clamps cooperate with each other, one end of the inner wall of each clamping groove is connected to a plurality of limit springs, and each group of limit springs is connected to a top plate at one end toward the clamp, the top plate is in contact with the corresponding clamp at all times, each of the clamps is in contact with a tool, and one end of the tool is fixed on the lathe.

[0007] By adopting the above technical solution, after the two first limit blocks are closed, the multiple clamps clamp the tool, and then the driving device controls the connecting arm to rotate, so that the tool is separated from the lathe, and the tool replacement is completed.

[0008] The utility model is further configured such that each of the clamps is slidably connected to a second limit block that passes through both ends of the clamp, each of the second limit blocks is provided with a limit hole, the first limit block passes through the corresponding limit hole, each of the first limit blocks is provided with a clamping top surface at one end facing the clamp, each of the first limit blocks is provided with a clamping inclined surface at one end away from the clamp, and the inner wall of each limit hole close to one end of the clamping top surface cooperates with the clamping inclined surface and the clamping top surface.

[0009] By adopting the above technical solution, the driving device controls the rotation of the connecting arm. When the second limit block on one side of the clamp touches the lathe, the corner on one side of the limit hole in the second limit block pushes the clamping slope. At this time, the clamping slope decomposes the thrust into a force in the vertical direction. Therefore, the first limit block moves outward until the corner on one side of the limit hole in the second limit block contacts the clamping top surface and stops. At this time, the two first limit blocks are closed to complete the clamping of the tool.

[0010] The utility model is further configured such that each of the first limit blocks is provided with a reset slope at one end opposite to the clamping slope and facing the clamping plate, each of the first limit blocks is provided with a reset top surface at one end away from the clamping plate, and the inner wall of each of the limit holes close to the reset top surface is matched with the reset slope and the reset top surface.

[0011] By adopting the above technical solution, the driving device controls the connecting arm to rotate away from the lathe. After stopping rotation, it presses the other side of the second limit block. At this time, the corner on the other side of the limit hole in the second limit block pushes the reset slope. At this time, the reset slope decomposes the thrust into a force in the vertical direction. Therefore, the first limit block retreats until the corner on the other side of the limit hole in the second limit block contacts the reset top surface and stops. At this time, the two first limit blocks open to release the clamping of the tool.

[0012] In summary, the utility model mainly has the following beneficial effects:

[0013] The utility model controls the rotation of the connecting arm through a driving device, and when the second limit block on one side of the clamp touches the lathe, the corner on one side of the limit hole in the second limit block pushes the clamping inclined surface, and the clamping inclined surface decomposes the thrust into a force in the vertical direction, so the first limit block moves outward until the corner on one side of the limit hole in the second limit block contacts the clamping top surface and stops. At this time, the two first limit blocks are closed. After the two first limit blocks are closed, multiple clamps clamp the tool, and then the driving device controls the connecting arm to rotate so that the tool is separated from the lathe. The driving device controls the connecting arm to rotate away from the lathe. After stopping rotation, press the other side of the second limit block. At this time, the corner on the other side of the limit hole in the second limit block pushes the reset inclined surface, and the reset inclined surface decomposes the thrust into a force in the vertical direction, so the first limit block retreats until the corner on the other side of the limit hole in the second limit block contacts the reset top surface and stops. At this time, the two first limit blocks are opened, the clamping of the tool is released, and the quick replacement of the tool is completed. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0021] The following describes an embodiment of the utility model based on its overall structure.

[0022] A tool changing auxiliary support mechanism for a CNC boring and milling machine clamp, such as Figure 1-5 As shown, it includes a driving device 1 and a lathe 13. The main structure of the driving device 1 is a rotating motor. The output end of the driving device 1 is connected to a connecting arm 2, and the upper and lower ends of the movable end of the connecting arm 2 are connected to a clamp 3. A first limit block 6 is arranged between the inside of the clamp 3, and the two first limit blocks 6 are provided with a clamping groove 17 at one end toward the middle. Each clamping groove 17 is connected to a rotating shaft 4 on both sides of the middle end, and the outer wall of each rotating shaft 4 is rotatably sleeved with a clamping plate 5, and every two clamping plates 5 on the same horizontal plane cooperate with each other. , and the two groups of clamps 5 cooperate with each other, one end of the inner wall of each clamping groove 17 is connected to a plurality of limit springs 15, and each group of limit springs 15 is connected to a top plate 16 at one end facing the clamping plate 5, and the top plate 16 is in contact with the corresponding clamping plate 5 at all times, each clamping plate 5 is in contact with the tool 14, and one end of the tool 14 is fixed on the lathe 13. After the two first limit blocks 6 are closed, multiple clamps 5 clamp the tool 14, and then the driving device 1 controls the connecting arm 2 to rotate, so that the tool 14 is separated from the lathe 13, and the replacement of the tool 14 is completed.

[0023] according to Figure 5 It can be seen that each clamp 3 is slidably connected to a second limit block 11 that passes through both ends of the clamp 3, each second limit block 11 is provided with a limit hole 12, the first limit block 6 passes through the corresponding limit hole 12, each first limit block 6 is provided with a clamping top surface 10 at one end facing the clamp 5, each first limit block 6 is provided with a clamping inclined surface 9 at one end away from the clamp 5, and the inner wall of each limit hole 12 close to the clamping top surface 10 is connected to the clamping inclined surface 9 and the clamping top surface 10. In coordination, the driving device 1 controls the connecting arm 2 to rotate. When the second limit block 11 on one side of the clamp 3 touches the lathe 13, the corner on the side of the limit hole 12 in the second limit block 11 pushes the clamping slope 9. At this time, the clamping slope 9 decomposes the thrust into a force in the vertical direction, so the first limit block 6 moves outward until the corner on the side of the limit hole 12 in the second limit block 11 contacts the clamping top surface 10 and stops. At this time, the two first limit blocks 6 are closed to complete the clamping of the tool 14.

[0024] according to Figure 5It can also be known that a reset bevel 7 is provided at the end of each first limit block 6 opposite to the clamping bevel 9 and facing the splint 5, and a reset top surface 8 is provided at one end of each first limit block 6 away from the splint 5. The inner wall of each limit hole 12 close to the reset top surface 8 cooperates with the reset bevel 7 and the reset top surface 8. The driving device 1 controls the connecting arm 2 to rotate away from the lathe 13. After stopping rotation, it presses the other side of the second limit block 11. At this time, the corner on the other side of the limit hole 12 in the second limit block 11 pushes the reset bevel 7. At this time, the reset bevel 7 decomposes the thrust into a force in the vertical direction. Therefore, the first limit block 6 retreats until the corner on the other side of the limit hole 12 in the second limit block 11 contacts the reset top surface 8 and stops. At this time, the two first limit blocks 6 open to release the clamping of the tool 14.

[0025] Working principle: The driving device 1 controls the connecting arm 2 to rotate. When the second limit block 11 on one side of the clamp 3 touches the lathe 13, the corner on one side of the limit hole 12 in the second limit block 11 pushes the clamping inclined surface 9. At this time, the clamping inclined surface 9 decomposes the thrust into a force in the vertical direction, so the first limit block 6 moves outward until the corner on one side of the limit hole 12 in the second limit block 11 contacts the clamping top surface 10 and stops. At this time, the two first limit blocks 6 are closed. After the two first limit blocks 6 are closed, multiple clamps 5 clamp the tool 14, and then the driving device 1 controls the connecting arm 2 to rotate. The arm 2 rotates to disengage the tool 14 from the lathe 13, and the driving device 1 controls the connecting arm 2 to rotate away from the lathe 13. After stopping rotation, it presses the other side of the second limit block 11. At this time, the corner on the other side of the limit hole 12 in the second limit block 11 pushes the reset slope 7. At this time, the reset slope 7 decomposes the thrust into a force in the vertical direction, so the first limit block 6 retreats until the corner on the other side of the limit hole 12 in the second limit block 11 contacts the reset top surface 8 and stops. At this time, the two first limit blocks 6 open, releasing the clamping of the tool 14, and completing the rapid replacement of the tool 14.
