[0050] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0051] It should be noted that when a metastructure is referred to as being "fixed to" or "set on" another metastructure, it can be directly on the other metastructure or indirectly on the other metastructure. When a metastructure is referred to as being "connected to" another metastructure, it can be directly connected to the other metastructure or indirectly connected to the other metastructure.

[0052] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element structure referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0053] 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.

[0054] The present application provides a jig which can be used to fix a soft pipe (hose) so as to facilitate processing of the pipe.

[0055] For example, when laser processing is performed on a hose used in medical treatment, the hose needs to be fixed so that the laser can process the circumference of the hose. Therefore, the fixture of the present application can fix the hose during laser processing without damaging the hose.

[0056] See also Figure 1 and Figure 2 The fixture includes a first clamping mechanism 100 , a second clamping mechanism 200 and a first supporting member 300 .

[0057] The length of the first support member 300 is longer than that of the pipe 900. The first support member 300 is used to support the pipe 900 after passing through the pipe of the pipe 900.

[0058] The first clamping mechanism 100 and the second clamping mechanism 200 are arranged opposite to each other and on the same axis. The first clamping mechanism 100 and the second clamping mechanism 200 respectively clamp the two ends of the first support member 300. That is, the first clamping mechanism 100 can clamp one end of the first support member 300, and the second clamping mechanism 200 can clamp the other end of the first support member 300.

[0059] When fixing the pipe 900, the first support member 300 can first be inserted into one end of the pipe of the pipe 900, and then passed out from the other end of the pipe, so as to realize the support of the pipe 900 by the first support member 300, and then the two ends of the first support member 300 are clamped and fixed by the first clamping mechanism 100 and the second clamping mechanism 200 respectively, thereby realizing the fixation of the first support member 300 and the pipe 900 supported by the first support member 300.

[0060] It can be seen that in the fixture of the present application, a first support member 300 is arranged between the relatively arranged and coaxial first clamping mechanism 100 and the second clamping mechanism 200. The first support member 300 passes through the tube 900 and the two ends of the first support member 300 are clamped by the first clamping mechanism 100 and the second clamping mechanism 200, so that the tube 900 can be supported. Since the length of the first support member 300 is longer than the length of the tube 900, it is also possible to avoid the first clamping mechanism 100 and the second clamping mechanism 200 clamping the tube 900 and causing damage to the tube 900.

[0061] In some embodiments, the first support member 300 may be made of a hard material such as a steel wire rope.

[0062] Furthermore, mutual friction can be generated between the outer wall of the first support member 300 and the inner wall of the tube 900, which can avoid mutual movement between the first support member 300 and the tube 900, so as to better ensure the stability of the first support member 300 supporting the tube 900, and also ensure the stretchability of the tube 900.

[0063] For example, in some embodiments, the cross-sectional diameter of the first support member 300 can be equal to or slightly smaller than the inner diameter of the tube 900. In this way, since the tube 900 is a soft material and has a certain length, friction can be generated between the tube 900 and the first support member 300 in the pipeline when they contact each other, thereby allowing the first support member 300 and the tube 900 to maintain a relatively static state.

[0064] See also Figure 1 and Figure 5 The fixture may further include a supporting mechanism 400, which is disposed between the first clamping mechanism 100 and the second clamping mechanism 200, and the supporting mechanism 400 is used to support the pipe 900 between the first clamping mechanism 100 and the second clamping mechanism 200 and the first supporting member 300 in the pipe of the pipe 900.

[0065] It is understandable that when the length of the tube 900 is long, the position near the middle of the tube 900 will sag under the action of gravity, so the support mechanism 400 can support the position near the middle of the tube 900 to avoid sagging in the middle of the tube 900 and affect the subsequent processing of the tube 900.

[0066] Furthermore, a through hole 410 may be provided on the support mechanism 400 . The through hole 410 is coaxial with the first clamping mechanism 100 and the second clamping mechanism 200 , and the through hole 410 can allow the pipe 900 to pass through so as to limit the position of the pipe 900 in the vertical direction.

[0067] Specifically, in some embodiments, see Figure 6 The support mechanism 400 may include a second support member 420 and a support block 430. The second support member 420 is provided with an assembly hole (not shown in the figure), the support block 430 is detachably arranged in the assembly hole, and the support block 430 may be provided with a through hole 410.

[0068] The second support member 420 may be an “L”-shaped structure.

[0069] It is understandable that when the fixture needs to support and fix the pipes 900 with different diameters, the support mechanism 400 can support the pipes 900 with different diameters by replacing the support blocks 430 with different diameters of the through holes 410 .

[0070] Furthermore, a top screw (not shown in the figure) may be provided on the second support member 420 , and the top screw abuts against the support block 430 to fix the support block 430 in the assembly hole.

[0071] For example, when the support block 430 needs to be replaced, the support block 430 can be loosened by the top screw and the support block 430 can be taken out from the assembly hole.

[0072] Further, see Figure 5 The support mechanism 400 may also include a first position adjustment structure 440, and the second support member 420 is arranged on the first position adjustment structure 440. The first position adjustment structure 440 enables the second support member 420 to move between the first clamping mechanism 100 and the second clamping mechanism 200 to adjust the position of the second support member 420 between the first clamping mechanism 100 and the second clamping mechanism 200, that is, to adjust the position of the support block 430 between the first clamping mechanism 100 and the second clamping mechanism 200, so that the support block 430 can support the pipe 900 at a suitable position.

[0073] Specifically, in some embodiments, the first position adjustment structure 440 may include a first slide rail and a first slider slidably disposed on the first slide rail, and the second support member 420 is disposed on the first slider. It can be understood that the position of the second support member 420 and the support block 430 mounted on the second support member 420 can be changed by adjusting the position of the first slider on the first slide rail.

[0074] See also Figure 1 and Figure 3 The fixture may further include a tensioning mechanism 500 , which is drivingly connected to the first clamping mechanism 100 to drive the first clamping mechanism 100 to move closer to or away from the second clamping mechanism 200 .

[0075] When the tensioning mechanism 500 drives the first clamping mechanism 100 to move in a direction away from the second clamping mechanism 200, the first clamping mechanism 100 and the second clamping mechanism 200 can tighten the first support member 300, thereby straightening the first support member 300. Similarly, the pipe 900 supported by the first support member 300 can also be straightened, thereby ensuring the processing effect of the pipe 900.

[0076] In addition, when the tensioning mechanism 500 drives the first clamping mechanism 100 to tighten the first support member 300, since the tube 900 and the first support member 300 are inserted into the through hole 410 of the support mechanism 400, the support mechanism 400 can also prevent the tube 900 from shaking in the vertical direction.

[0077] Specifically, in some embodiments, see Figure 3 The tensioning mechanism 500 may include a tensioning driving member 510 and a sliding member 520. The first clamping mechanism 100 is disposed on the sliding member 520, and the tensioning driving member 510 is drivingly connected to the first clamping mechanism 100.

[0078] It can be understood that the sliding member 520 can support the first clamping mechanism 100, and the tension driving member 510 can drive the first clamping mechanism 100 to move on the sliding member 520. The sliding member 520 can be a guide rail; and the tension driving member 510 can be a cylinder.

[0079] In some embodiments, a buffer 530 may be further provided at the end position of the moving path of the first clamping mechanism 100 , and the buffer 530 buffers the first clamping mechanism 100 .

[0080] See also Figure 1 and Figure 5The fixture may further include a compatible mechanism 600, which is driven and connected to the first clamping mechanism 100 and / or the second clamping mechanism 200 so that the first clamping mechanism 100 and the second clamping mechanism 200 are moved closer to or farther from each other, thereby adjusting the distance between the first clamping mechanism 100 and the second clamping mechanism 200, so that the first clamping mechanism 100 and the second clamping mechanism 200 can clamp the first support members 300 of different lengths, thereby supporting and fixing the pipes 900 of different lengths.

[0081] For example, in some embodiments, the compatible mechanism 600 can drive the first clamping mechanism 100 to move toward or away from the second clamping mechanism 200 to adjust the distance between the first clamping mechanism 100 and the second clamping mechanism 200 .

[0082] In other embodiments, the compatible mechanism 600 can drive the second clamping mechanism 200 to move toward or away from the first clamping mechanism 100 to adjust the distance between the first clamping mechanism 100 and the second clamping mechanism 200 .

[0083] Of course, the compatible mechanism 600 can also drive the first clamping mechanism 100 to move toward or away from the second clamping mechanism 200, and can also simultaneously drive the second clamping mechanism 200 to move toward or away from the first clamping mechanism 100.

[0084] See also Figure 5 The compatible mechanism 600 may include a second slide rail 610 , a second slider 620 , a screw rod (not shown) and a rotating member 630 .

[0085] The second sliding block 620 is slidably disposed on the second sliding rail 610 , and the first clamping mechanism 100 or the second clamping mechanism 200 is disposed on the second sliding block 620 .

[0086] The screw rod is rotatably arranged on the second slide rail 610, and the second slider 620 is threadedly connected to the screw rod and can move along the length direction of the screw rod. That is, when the screw rod rotates along its axis, the second slider 620 can move on the screw rod.

[0087] The rotating member 630 is connected to the screw rod so that the screw rod can rotate.

[0088] In some embodiments, the rotating member 630 may be a hand-cranked wheel or a motor.

[0089] The second slide rail 610 may include two oppositely disposed seats 611 , a guide plate 612 may be disposed between the two seats 611 , the second slider 620 is slidably disposed on the guide plate 612 , and both ends of the screw rod are rotatably disposed on the two seats 611 .

[0090] When the compatible mechanism 600 is drivingly connected to the first clamping mechanism 100, and the first clamping mechanism 100 is connected to the tensioning mechanism 500, refer to Figure 3 The fixture may further include a mounting seat 700 , the compatible mechanism 600 is drivingly connected to the mounting seat 700 , and the tensioning driving member 510 and the sliding member 520 are disposed on the mounting seat 700 .

[0091] For example, in some embodiments, the tension driving member 510 and the sliding member 520 may be disposed on the second sliding block 620 .

[0092] That is to say, the compatible mechanism 600 can simultaneously drive the first clamping mechanism 100 and the tensioning mechanism 500 to move, and adjust the positions of the first clamping mechanism 100 and the tensioning mechanism 500 .

[0093] Specifically, a suitable length of the first support member 300 can be selected according to the length of the tube 900, and then the distance between the first clamping mechanism 100 and the second clamping mechanism 200 can be adjusted through the compatible mechanism 600 according to the length of the first support member 300, so that the first clamping mechanism 100 can tighten the first support member 300 under the action of the tensioning mechanism 500.

[0094] Furthermore, in order to make the structure of the fixture more compact, see Figure 1 The fixture may further include a vertical plate 800 , the vertical plate 800 is disposed on the sliding member 520 , the first clamping mechanism 100 is disposed on the vertical plate 800 , the tensioning driving member 510 is drivingly connected to the vertical plate 800 , and the tensioning driving member 510 is located below the first clamping mechanism 100 .

[0095] See also Figure 3 The first clamping mechanism 100 may include a first clamping jaw 110 and a first rotation driving structure 120 , the first rotation driving structure 120 is drivingly connected to the first clamping jaw 110 , and the first clamping jaw 110 is used to clamp one end of the first support member 300 .

[0096] See also Figure 4 The second clamping mechanism 200 may include a second clamping jaw 210 and a second rotation driving structure 220 , the second rotation driving structure 220 is drivingly connected to the second clamping jaw 210 , and the second clamping jaw 210 is used to clamp the other end of the first support member 300 .

[0097] Specifically, the first rotation driving structure 120 drives the first clamping jaw 110 to rotate, thereby causing the first clamping jaw 110 to drive the first support member 300 to rotate, and the second rotation driving structure 220 drives the second clamping jaw 210 to rotate, thereby causing the second clamping jaw 210 to drive the first support member 300 to rotate. When the rotation frequencies of the first clamping jaw 110 and the second clamping jaw 210 are the same, the first support member 300 can be rotated around its axis. In some embodiments, mutual friction can be generated between the outer wall of the first support member 300 and the inner wall of the tube 900. Therefore, when the first support member 300 rotates, the tube 900 can also rotate with the first support member 300 under the action of the mutual friction between the first support member 300 and the first support member 300. It can be understood that when the tube 900 can rotate, it is beneficial to process the outer peripheral surface of the tube 900.

[0098] The first rotation driving structure 120 and the second rotation driving structure 220 may be a rotary motor, or a combination of a rotary motor and a reducer. The first clamping jaw 110 and the second clamping jaw 210 may be pneumatic clamping jaws.

[0099] Furthermore, in some embodiments, the first clamp 110 can be disposed on the vertical plate 800 via the first rotation drive structure 120. At this time, the tension drive member 510 can be located below the first rotation drive structure 120, so that the structure disposed on the mounting base 700 can be more compact.

[0100] See also Figure 4 The second clamping mechanism 200 may also include a second position adjustment structure 230, which is connected to the second rotary drive structure 220 so that the second rotary drive structure and the second clamp 210 can move synchronously in the vertical direction and / or horizontal direction to adjust the position of the second rotary drive structure and the second clamp 210 in the horizontal direction and / or vertical direction.

[0101] It is understandable that by adjusting the horizontal and / or vertical positions of the second rotary drive structure and the second clamp 210 , the second clamp 210 and the first clamp 110 can be ensured to be on the same axis to ensure the supporting effect of the first support member 300 on the pipe 900 .

[0102] Specifically, see Figure 4 The second position adjustment structure 230 may include a fixed plate 231 and a movable plate 232. The second rotation drive structure 220 is arranged on the movable plate 232. A waist hole 233 is arranged on the movable plate 232. The movable plate 232 is arranged on the fixed plate 231 through the cooperation of a height adjustment bolt 234 and the waist hole 233. The movable plate 232 and the fixed plate 231 are also provided with horizontal adjustment bolts 235 in the length direction of the waist hole 233.

[0103] It can be understood that by adjusting the height adjustment bolt 234, the position of the movable plate 232 in the vertical direction relative to the fixed plate 231 can be adjusted, and by adjusting the horizontal adjustment bolt 235, the position of the movable plate 232 in the horizontal direction relative to the fixed plate 231 can be adjusted. When the movable plate 232 moves in the horizontal direction relative to the fixed plate 231, the height adjustment bolt 234 can move in the waist hole 233 to avoid interference.

[0104] Preferably, in some embodiments, the length direction of the waist hole 233 is perpendicular to the axis direction between the first clamping jaw 110 and the second clamping jaw 210 .

[0105] In this way, the distance between the first clamping mechanism 100 and the second clamping mechanism 200 can be adjusted through the compatible mechanism 600, and the position of the second clamping mechanism 200 in the vertical direction and the horizontal direction perpendicular to the coaxial direction of the first clamping mechanism 100 and the second clamping mechanism 200 can be adjusted through the second position adjustment structure 230. If the compatible mechanism 600 is connected to the first clamping mechanism 100, this can not only realize multi-directional and multi-position adjustment, but also facilitate the setting of the compatible mechanism 600 and the second position adjustment structure 230.

[0106] In addition, the present application also provides a laser device, including a laser and the jig in the above embodiment, wherein the laser is arranged on one side of the jig, and the laser is used to process the pipe.

[0107] 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.
