Description

Technical Field

[0001] The present application belongs to the field of laser processing technology, and more specifically, relates to a support mechanism and laser cutting equipment. Background Art

[0002] When the laser tube cutting machine cuts a long workpiece, one end of the workpiece will extend out of the chuck of the laser tube cutting machine, causing the workpiece to swing and sag due to its own gravity during the cutting process. In order to prevent the bending of the workpiece from affecting the cutting accuracy, manufacturers usually set a reducing wheel to support the extended workpiece.

[0003] However, the part of the reducing wheel that contacts the workpiece is generally an arc groove, which cannot fit well with non-circular workpieces such as square or rectangular structures. For example, when the reducing wheel is rising, if the arc groove of the reducing wheel first contacts one of the edges of the workpiece, the workpiece may be overturned and deflected if the reducing wheel continues to rise. At this time, if the chuck clamps the workpiece, it may cause damage to the chuck or the workpiece. Utility Model Content

[0025] Optionally, the lifting structure is arranged on the side of the mounting member, and the lifting structure and the mounting member are connected via a driving connection member.

[0036] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of some applications, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0037] The present application provides a support mechanism that can be used to support a workpiece. For example, the support mechanism can be set on a laser processing device such as a laser cutting device, and the support mechanism can be used to support a workpiece extending out of a chuck on the laser processing device to prevent the workpiece from swinging or sagging due to its own gravity during the cutting process.

[0038] See also Figure 1 , the supporting mechanism includes a first supporting member 100, a second supporting member 200 and a lifting structure 300.

[0039] A groove 110 is provided on the surface of the first support member 100 . The groove 110 is used to accommodate the workpiece and can contact with the workpiece to support the workpiece.

[0040] Furthermore, the cross section of the groove 110 is an arc surface.

[0041] The second support member 200 is disposed on one side of the first support member 100. The second support member 200 supports the workpiece simultaneously when the groove 110 supports the workpiece.

[0042] The lifting structure 300 is drivingly connected to the first supporting member 100 and the second supporting member 200 respectively to drive the first supporting member 100 and the second supporting member 200 to perform lifting motion.

[0043] Specifically, when the lifting structure 300 drives the first support member 100 and the second support member 200 to rise, the groove 110 of the first support member 100 supports the workpiece, and at the same time, the second support member 200 supports the workpiece synchronously.

[0044] That is to say, after the lifting structure 300 drives the first support member 100 and the second support member 200 to rise, the second support member 200 can synchronously support the workpiece while the groove 110 of the first support member 100 supports the workpiece. Since the second support member 200 can synchronously support the workpiece, if the groove 110 of the first support member 100 causes the workpiece to deflect during the process of supporting the workpiece, the second support member 200 can limit the deflection of the workpiece, thereby preventing the support mechanism from causing the workpiece to be off-axis when supporting the workpiece.

[0045] See also Figure 1The supporting mechanism may further include a mounting member 400 , the first supporting member 100 and the second supporting member 200 are respectively disposed on the mounting member 400 , and the lifting structure 300 is drivingly connected to the mounting member 400 .

[0046] Specifically, the lifting structure 300 drives the first support member 100 and the second support member 200 to perform lifting motion synchronously through the mounting member 400. This method can facilitate the lifting structure 300 to drive the first support member 100 and the second support member 200 to move simultaneously.

[0047] See also Figure 1 In some embodiments, the first support member 100 is rotatably disposed on the mounting member 400 , and the groove 110 is disposed on the circumferential surface of the first support member 100 along the circumferential direction of the first support member 100 .

[0048] In some embodiments, the depth of the groove 110 in the radial direction of the first support member 100 increases continuously along the circumferential direction of the first support member 100, and the opening of the groove 110 in the axial direction of the first support member 100 increases continuously along the circumferential direction of the first support member 100. In this way, the groove 110 can support workpieces of different sizes, and when the groove 110 supports workpieces of different sizes, the axis of the workpiece can be at the same position, thereby ensuring the processing accuracy of workpieces of different sizes.

[0049] In actual use, according to the size of the workpiece, the first support member 100 can be rotated so that the groove 110 with the appropriate opening size and depth in the first support member 100 can be rotated to support the workpiece.

[0050] See also Figure 1 In some embodiments, in order to prevent the first support member 100 from rotating when supporting the workpiece, a plurality of positioning holes 120 may be respectively provided on the end surface of the first support member 100 along the circumferential direction of the first support member 100, and a latch 130 may be provided on the mounting member 400, and the latch 130 cooperates with the positioning hole 120 to fix the first support member 100.

[0051] Specifically, after the first support member 100 is rotated to select a portion of the groove 110 with a suitable depth and opening size to support the workpiece, the first support member 100 can be fixed by inserting the pin 130 into the positioning hole 120 .

[0052] See also Figure 1 In some embodiments, the second support member 200 can be movably disposed on the mounting member 400 along a vertical direction.

[0053] It can be understood that since the second support member 200 needs to be able to support the workpiece synchronously when the groove 110 supports the workpiece, when grooves 110 with different depths and opening sizes are selected to support the workpiece, the second support member 200 can be positioned in the vertical direction accordingly so that the second support member 200 can also be able to support the workpiece synchronously when the groove 110 supports the workpiece.

[0054] In some embodiments, the height of the second support member 200 can be adjusted by manually adjusting the second support member 200 to move in the vertical direction.

[0055] In other embodiments, the second support member 200 may be elastically connected so that the second support member 200 can move in the vertical direction.

[0056] See also Figure 1 The second support member 200 may specifically include a support portion 210 and a connection portion 220. The support portion 210 is located at one side of the first support member 100. The support portion 210 supports the workpiece when the groove 110 supports the workpiece. The connection portion 220 is disposed on the mounting member 400. The connection portion 220 can move in a vertical direction on the mounting member 400. This structure is convenient for supporting the workpiece and also convenient for being movably disposed on the mounting member 400.

[0057] Furthermore, the support portion 210 extends on the connection portion 220 along a radial direction parallel to the first support member 100 , so as to be able to fully support the workpiece at least in the radial direction parallel to the first support member 100 .

[0058] It can be understood that when the support portion 210 can completely support the workpiece in a radial direction parallel to the first support member 100, it means that the support portion 210 can completely fit with the bottom of the workpiece in a radial direction parallel to the first support member 100 to avoid the bottom of the workpiece being suspended in the air. In this way, when the groove 110 supports the workpiece, the support portion 210 can better limit the deflection of the workpiece.

[0059] See also Figure 1 It is understandable that, in some embodiments, the second support member 200 can be disposed on the mounting member 400 by means of an elastic connection, so that the second support member 200 can adaptively support workpieces of different sizes.

[0060] For example, a linear bearing 500 may be further provided on the mounting member 400 , and the connecting portion 220 may be slidably matched with the linear bearing 500 , so that the connecting portion 220 may move along the vertical direction on the mounting member 400 .

[0061] Furthermore, an elastic member 600 is sleeved on the connecting portion 220 between the supporting portion 210 and the linear bearing 500 , and the elastic member 600 enables the supporting portion 210 to move in the vertical direction when subjected to pressure.

[0062] For example, in some embodiments, in order to ensure that the support portion 210 can synchronously support the workpiece when the groove 110 supports the workpiece, during the process of the upgraded structure driving the first support member 100 and the second support member 200 to rise, the support portion 210 of the first support member 100 can first contact the workpiece to support the workpiece, at this time, the upgraded structure continues to drive the first support member 100 and the second support member 200 to rise, and during the process of the second support member 200 continuing to rise, the support portion 210 of the second support member 200 is subjected to the downward pressure of the workpiece and can move in the vertical direction under the action of the elastic member 600, and the elastic member 600 gradually shrinks until the groove 110 of the first support member 100 can contact the workpiece and support the workpiece. In addition, since the elastic member 600 can provide elastic force to the support portion 210, the support portion 210 can closely fit the workpiece to support the workpiece, and this method can better limit the deflection that may occur when the workpiece contacts the groove 110.

[0063] In addition, in some embodiments, the workpiece needs to rotate along its axis during processing, such as cutting, so when the support portion 210 is movably disposed on the mounting member 400 in the vertical direction through the elastic member 600, the support portion 210 can both support the workpiece and not affect the rotation of the workpiece. It can be understood that when the workpiece rotates, the support portion 210 can move in the vertical direction under the action of the elastic member 600.

[0064] Furthermore, the connection portion 220 may also be connected to a stopper 700 , and the stopper 700 is located at one end of the linear bearing 500 away from the support portion 210 , and the stopper 700 is used to prevent the connection portion 220 from being separated from the linear bearing 500 under the action of the elastic member 600 .

[0065] Optionally, a thread (not shown in the figure) may be provided on the outer peripheral surface of the connecting portion 220, and the stopper portion 700 and the connecting portion 220 are connected via the thread.

[0066] It can be understood that the stop portion 700 is connected to the connecting portion 220 via a thread, so that the position of the stop portion 700 on the connecting portion 220 can be adjusted. By adjusting the position of the stop portion 700 on the connecting portion 220, the height of the support portion 210 can be adjusted, and at the same time, the elastic force of the elastic member 600 can be adjusted, so that the support mechanism can be compatible with workpieces in different processing conditions, thereby improving the compatibility of the support mechanism.

[0067] In some embodiments, the stopper 700 may be a nut.

[0068] See also Figure 1 In some embodiments, in order to facilitate the support mechanism to be arranged on the laser cutting device, to avoid interference between the lifting structure 300 of the support mechanism and the laser cutting device, and to make the laser cutting device more compact, the lifting structure 300 can be arranged on the side of the mounting member 400, and the lifting structure 300 and the mounting member 400 are connected by a driving connection member 800. The lifting structure 300 can be a lifting cylinder.

[0069] In addition, the present application also provides a laser cutting device, including a laser and a support mechanism in the above embodiment, wherein the laser is used to cut a workpiece supported by the support mechanism.

[0070] The above are only preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of some applications should be included in the protection scope of some applications.
