The carbon fiber needled preform is a three-dimensional network structure formed by connecting Z-direction fiber bundles by needling, for example: the prefabricated parts of the carbon-carbon crucible, the heat preservation cylinder, the guide cylinder, the crucible support and the like in the thermal field component of the single crystal furnace all adopt needling technology. The parameters of the needling (such as the initial needling distance, needling depth, needling height, inclination angle and the like) directly influence the size and length of the Z-direction fiber bundles formed during needling, and the thickness of the working section determines the size of the needle hole of the preform. Therefore, the testing of critical parameters of the lancet needs to be tightly controlled.

Referring to FIG. 1, the lancet essentially comprises a needle handle, a curved handle attached to one end of the needle handle, and a needle hook attached to the other end of the needle handle. During the inspection process, the hook portion needs to be stably fixed, and at the same time, the hook portion needs to be at a proper viewing angle, for example: under an electron microscope, the needle hook can be observed at a vertically downward angle. However, conventional clamps typically employ miniature vice clamps to clamp the needle shank. After the needle handle is clamped, if the needle hook angle is not opposite or the observation angle needs to be changed in the inspection process, the needle handle cannot be directly rotated because the needle handle is clamped by the jaw. Meanwhile, even if the jaw is loosened to adjust the observation angle, the adjusted angle is easy to deviate due to vibration when the jaw is re-clamped, and the puncture needle is difficult to fix at an ideal measurement position, so that the accuracy of a test result is affected.

To this end, referring to fig. 1-3, the present application provides a lancet testing fixture 100, the lancet testing fixture 100 comprising: base 10, clamp 20 and elastic member 30. The base 10 is provided with a fixing position 11 for placing the needle handle 210 of the puncture needle 200, the clamping piece 20 is movably arranged on the base 10 through the elastic component 30, and the clamping piece 20 elastically abuts against the fixing position 11 under the action of the elastic component 30.

The lancet checking fixture 100 described above overcomes the elastic force of the elastic member 30 during the clamping process, so that the clamping member 20 is separated from the base 10; next, the shank 210 of the lancet 200 is placed on the fixture 11 and the clamping angle of the shank 210 is adjusted so that the hook 230 on the lancet 200 can be at the proper viewing angle; finally, the clamp 20 is released so that it will press against the needle shank 210 under the force of the spring force, thereby stabilizing the clamping of the lancet 200. Because the clamping piece 20 abuts against the fixing position 11 under the action of the elastic component 30, if the clamping angle of the needle handle 210 needs to be adjusted again, the needle handle 210 can be directly rotated to realize rapid adjustment under the state that the puncture needle 200 is clamped, so that the clamping of the puncture needle 200 is rapid and efficient. Meanwhile, the positioning of the puncture needle 200 is accurate due to the convenience in adjustment, which is beneficial to improving the accuracy of the test result.

In addition, the elastic component 30 is adopted in the present embodiment, the clamping piece 20 is used for stably clamping the lancet 200, so that when the needle handle 210 is adjusted, the needle handle 210 is always subjected to elastic interference action in the rotation adjustment process, and the adjusted angle is not affected by external vibration or shake, so that the observation angle of the needle hook is easily changed, and the positioning of the lancet 200 is more accurate.

It should be noted that the lancet 200 refers to a component applied to a needling process of a preform, and may include a shank 210, a bent shank 220 connected to one end of the shank 210, and a hook 230 connected to the other end of the shank 210. The curved handle 220 is arranged to bend relative to the needle handle 210; the number of hooks 230 is plural, similar to the barb structure, so that in the inspection process, if each hook 230 is inspected, the clamping angle of the lancet 200 needs to be adjusted multiple times so that different hooks 230 are at proper viewing angles.

It should be noted that, the fixing portion 11 is a position where the pointer handle 210 may be placed, and may be configured in a groove-like structure or a planar structure. When the fixing portion 11 is in a planar structure, in order to avoid the needle handle 210 from being offset during the clamping process, a plurality of anti-slip stripes and the like may be disposed on the fixing portion 11.

The clamping member 20 is movably disposed on the base 10, and the moving manner thereof can have various designs, such as: the clamping member 20 is rotatably mounted on the base 10, such as: the clamping piece 20 is fixed on the base 10 through a torsion spring and other structures; alternatively, the clamping member 20 may be slidably mounted on the base 10, such as: the clamping member 20 is connected with the base 10 through a spring.

The number of the elastic members 30 may be one or more. When the number of the elastic components 30 is plural, the clamping piece 20 is movably arranged on the base 10 through the plural elastic components 30, so that the stress on the clamping piece 20 is more balanced, which is beneficial to improving the stability of the structure.

Further, referring to fig. 2 and 4, the lancet checking fixture 100 further includes a positioning member 40 disposed on the base 10, and a positioning slot 41 is disposed on the positioning member 40 for inserting the bent shank 220 of the lancet 200. The positioning groove 41 is disposed opposite to the fixed position 11, wherein the bent handle 220 is disposed at one end of the needle handle 210. It will be appreciated that when the shank 210 is placed in the fixing location 11, the bent shank 220 of the lancet 200 can be inserted into the corresponding positioning slot 41 such that the clamping angle of the shank 210 is fixed such that the needle hook 230 is at the proper viewing angle. Thus, the positioning slot 41 of the positioning member 40 is utilized to facilitate rapid and accurate positioning of the lancet 200, which is beneficial to improving accuracy of the test result.

It should be noted that the positioning groove 41 may be a concave structure on one side of the positioning member 40, or may be a through groove structure penetrating through the positioning member 40. Meanwhile, the position of the positioning slot 41 on the positioning member 40 may be preset according to the observation angle of the hook portion 230, for example: when the curved shank 220 is inserted into the positioning slot 41, the hook 230 on the shank 210 is at the right viewing angle.

The number of the positioning grooves 41 may be one or more. When the number of the positioning grooves 41 is plural, the bending shank portion 220 may be inserted into different positioning grooves 41 so that different needle hook portions 230 are at a proper viewing angle.

It should be noted that, the positioning member 40 may be detachably connected to the base 10, or may be non-detachably connected to the base. Wherein, the detachable connection can be, but is not limited to, a bolt connection, a clamping connection, a magnetic attraction and the like. The non-detachable connection may be, but is not limited to, a welded, riveted, integrally formed connection. The integrally formed connection can be in injection molding, die casting, 3D printing and other modes. In particular, referring to fig. 2 and 3, the base 10 is provided with a fixing hole 14, and the positioning member 40 is fixed in the fixing hole 14 by a fastener 60.

Further, referring to fig. 1 and 3, the fixing portion 11 is configured as a groove 11a extending along the predetermined direction X, and the positioning member 40 is disposed on a side surface of the base 10 along the predetermined direction X. The positioning groove 41 extends in a direction intersecting the preset direction X. Since the curved handle 220 is bent at a certain angle with respect to the needle handle 210, when the needle handle 210 is placed at the fixing location 11, the curved handle 220 is in an intersecting relationship with the extending direction of the fixing location 11 (i.e., the preset direction X). Therefore, the extending direction of the positioning slot 41 is intersected with the preset direction X, so that the bent handle 220 is convenient to be inserted into the positioning slot 41, and the needle hook 230 on the needle 200 can be ensured to be at a proper observation angle, and the inspection efficiency is improved.

It should be noted that, the extending direction of the positioning slot 41 is intersected with the preset direction X, for example: the extending direction of the positioning slot 41 is perpendicular to the preset direction X, and at this time, during the structural assembly process, a side surface of the positioning member 40 may be disposed perpendicular to the preset direction X, so that the extending direction of the positioning slot 41 is always perpendicular to the preset direction X.

It should be noted that, to facilitate insertion of the bent portion 220 of the lancet 200 on the fixing portion 11 into the positioning slot 41, one end of the recess 11a may extend to and penetrate through a side of the base 10 along the predetermined direction X. Of course, the groove 11a may also extend along the preset direction X and respectively penetrate through two opposite sides of the base 10 along the preset direction X.

In addition, in order to make the clamping of the lancet 200 more stable, the shape of the groove 11a may be designed in a semicircular shape; can also be designed into a V shape. Such as: the groove wall of the groove 11a comprises a first side wall 111 and a second side wall 112 which are oppositely arranged, and the distance between the first side wall 111 and the second side wall 112 is larger as the distance is closer to the notch of the groove 11a, so that the puncture needle 200 can be prevented from shaking in the groove 11a, and the clamping stability is improved; but also facilitates the handle 210 being in a horizontal state when clamped, improving the accuracy of the test.

In some embodiments, referring to fig. 4, the positioning slot 41 includes a plurality of positioning slots. One ends of all the positioning grooves 41 intersect and define positioning holes 42, and all the positioning grooves 41 are circumferentially spaced along the positioning holes 42, and the positioning holes 42 are opposite to the grooves 11a in the preset direction X. It can be seen that the positioning hole 42 is opposite to the groove 11a in the predetermined direction X, so that the shank 210 disposed in the groove 11a can be secured, and one end thereof can correspondingly extend into the positioning hole 42. Since the positioning holes 42 are defined by one end of each positioning groove 41, the shank portion 210 placed in the groove 11a can easily insert the shank portion 220 into the corresponding positioning groove 41 so that the corresponding needle hook portion 230 is at a proper viewing angle.

It should be noted that the number of the positioning slots 41 may be not limited to three as shown in fig. 4, but may be other. Such as: the number of the positioning grooves 41 can be, but not limited to, two, four, five, etc., and can be determined according to the number of the needle hook portions 230 at different positions.

In some embodiments, referring to fig. 2 and 5, the elastic member 30 includes an elastic member 32 and a guiding shaft 31. One of the base 10 and the clamping member 20 is provided with a guide hole 21, the other is provided with a guide shaft 31 penetrating into the guide hole 21, and the elastic member 32 is used for driving the clamping member 20 to abut against the fixing position 11. It can be known that the distribution positions of the guide holes 21 and the guide shafts 31 can be two, in which, the guide holes 21 are disposed on the base 10, and the guide shafts 31 are disposed on the clamping members 20; 2. the guide hole 21 is provided on the holder 20, and the guide shaft 31 is provided on the base 10. In any event, however, the clamping member 20 can be moved toward or away from the mounting location 11 on the base 10 by the engagement of the guide shaft 31 with the guide hole 21 to effect clamping or unclamping of the lancet 200.

In the embodiment, the elastic component 30 is designed into the guide shaft 31 and the elastic component 32, and the guide shaft 31 is matched with the guide hole 21, so that the movement of the clamping piece 20 is more stable, and the puncture needle 200 is clamped or unclamped stably. Simultaneously, the clamping piece 20 is used for elastically pressing the puncture needle 200 on the fixing position 11 by the elastic piece 32, so that the puncture needle 200 is stably clamped; but also allows the lancet 200 to be rotated under pressure when clamped to adjust the viewing angle of the needle hook 230.

It should be noted that, the elastic member 32 may be mounted between the clamping member 20 and the base 10 in various manners, and only the clamping member 20 can be elastically abutted against the fixing portion 11. Such as: the elastic piece 32 is connected between the base 10 and the clamping piece 20, and the clamping piece 20 is abutted against the fixing position 11 in a pulling mode; alternatively, the elastic member 32 is disposed at a side of the clamping member 20 facing away from the base 10, so as to press the clamping member 20 against the fixing portion 11. The elastic member 32 may be a spring, elastic rubber, elastic metal sheet, or the like.

Further, referring to fig. 2 and 5, the guide shaft 31 is disposed on the base 10 and penetrates the guide hole 21 of the clamping member 20. The part of the guide shaft 31 extending out of the guide hole 21 is provided with a limiting part 33, and the elastic piece 32 is sleeved on the guide shaft 31 and is abutted between the limiting part 33 and the clamping piece 20. Thus, the clamping member 20 is lifted or jacked up, and the elastic member 32 is compressed, so that the clamping member 20 can be separated from the fixing position 11; when the clamping member 20 is released, the clamping member 20 moves towards the fixing position 11 under the elastic force of the elastic member 32, so that the clamping member 20 elastically abuts against the fixing position 11.

The limiting portion 33 may be fixed to the guide shaft 31; and can also be in an adjustable state. The stopper 33 is configured such that a position on the guide shaft 31 can be adjusted in the axial direction of the guide shaft 31. When the position of the limiting part 33 on the guide shaft 31 is adjustable, the clamping force of the clamping piece 20 on the base 10 can be adjusted by moving the limiting part 33 upwards or downwards. Such as: the limiting portion 33 is screwed on the guide shaft 31 and can be adjusted up and down along the axial direction of the guide shaft 31, for example, the limiting portion 33 can be designed as a nut or the like.

The guide shaft 31 is disposed on the base 10 in various manners, such as: threaded connection, clamping connection, pin connection, welding and the like. In some embodiments, referring to fig. 2 and 3, the base 10 is provided with a mounting hole 12, and one end of the guiding shaft 31 is inserted into the mounting hole 12. Meanwhile, when the elastic component 30 includes two, the number of the mounting holes 12 is also two, and the two mounting holes 12 are arranged on the base 10 at intervals along the preset direction X, so that the guide shafts 31 of the elastic component 30 are distributed along the preset direction X, and the guiding and the stress of the clamping piece 20 are more balanced.

It will be appreciated that the clamping member 20 is movable on the guide shaft 31 with the guide hole 21 being of a through-hole configuration, i.e. the guide hole 21 is provided through the clamping member 20.

In some embodiments, referring to FIG. 2, the lancet verification clamp 100 further comprises an operating member 50. The operating member 50 is movably disposed on the base 10 and is used to separate the clamping member 20 from the fixed position 11. Thus, by triggering the operating member 50, the clamping member 20 can be separated from the fixing portion 11, so that the clamping operation of the lancet 200 is greatly facilitated, and the inspection efficiency is improved.

It should be noted that, the operating member 50 refers to a member that facilitates separation of the clamping member 20 from the fixing portion 11, and various manners of driving separation of the clamping member 20 from the fixing portion 11 by the operating member 50 are provided, such as: the operating piece 50 and the clamping piece 20 can be driven by meshing of a gear and a rack, and the clamping piece 20 is driven to be separated from the fixed position 11 by the up-and-down movement of the rack; alternatively, a link is provided between the operating element 50 and the holder 20, which is rotatably connected to each other, and the holder 20 is opened by pushing the connection portion of the link, thereby achieving separation and the like.

Further, referring to fig. 2 and 3, a side surface of the base 10 facing the clamping member 20 is provided with a mounting groove 13. The operating member 50 is rotatably disposed on a groove wall of the mounting groove 13, and one end of the operating member 50 is configured to rotatably abut against a side surface of the clamping member 20 facing the base 10, and separate the clamping member 20 from the fixing portion 11. Therefore, during the clamping process, one end of the operating member 50 is pressed down, so that the other end of the operating member 50 is tilted up and abuts against the clamping member 20, and the clamping member 20 is lifted up to be separated from the fixing position 11. Thus, the clamping operation of the lancet 200 is greatly facilitated.

In addition, after the lancet 200 is placed, one end of the operating member 50 can be released so that the clamping member 20 is pressed down on the lancet 200 by the resilient member 30 to achieve a stable grip.

For the convenience of triggering the operation member 50, please refer to fig. 2 and 6, the operation member 50 may include a first member 51 and a second member 52, the first member 51 and the second member 52 are connected to each other and disposed at an angle, and an angle opening between the first member 51 and the second member 52 is disposed towards one side of the clamping member 20. The first member 51 and/or the second member 52 are/is connected to the groove wall of the mounting groove 13 through a rotation shaft 53, one end of the first member 51 is located at a side of the clamping member 20 facing the base 10 and is used for abutting against the clamping member 20, and one end of the second member 52 is located outside the clamping member 20. Thus, by pressing one end of the second member 52, one end of the first member 51 is tilted and the holder 20 is lifted to be separated from the fixing position 11. Wherein, the operation member 50 is mounted in the mounting groove 13, the shaft hole 15 is provided on the wall of the mounting groove 13, and the rotation shaft 53 is inserted into the shaft hole 15.

It should be noted that, the length of the second member 52 may be designed to be greater than that of the first member 51, which is not only beneficial for the one end of the second member 52 to extend out of the mounting groove 13, but also beneficial for increasing the pressing amount of the second member 52 and improving the convenience of operation.

It should be noted that, when the elastic members 30 include two elastic members 30, the two elastic members 30 are spaced apart along the predetermined direction X, and the mounting groove 13 is located between the two elastic members 30. Wherein one end of the mounting groove 13 may extend below the clamping member 20 in a direction intersecting (e.g., perpendicular to, etc.) the predetermined direction X. By the design, the structure design of the puncture needle inspection clamp 100 is more reasonable, the movement of the clamping piece 20 is driven to be more balanced, and the stress is more balanced, so that the stability of the structure is improved.

In some embodiments, referring to FIG. 7, a lancet verification clamping operation method, employing the lancet verification clamp 100 of any of the above, comprises the steps of:

s100, driving the clamping piece 20 to overcome the elastic force of the elastic part 30 and separate from the fixed position 11 on the base 10;

s200, placing the needle handle 210 of the puncture needle 200 on the fixed position 11, and adjusting the clamping angle of the needle handle 210;

s300, loosening the clamping piece 20, so that the clamping piece 20 clamps the needle handle 210 on the fixing position 11 under the elastic force.

The above-mentioned lancet checking clamping operation method, adopting the above lancet checking fixture 100, overcomes the elastic force of the elastic member 30 during clamping, so that the clamping member 20 is separated from the base 10; next, the shank 210 of the lancet 200 is placed on the fixture 11 and the clamping angle of the shank 210 is adjusted so that the hook 230 on the lancet 200 can be at the proper viewing angle; finally, the clamp 20 is released so that it will press against the needle shank 210 under the force of the spring force, thereby stabilizing the clamping of the lancet 200. Because the clamping piece 20 abuts against the fixing position 11 under the action of the elastic component 30, if the clamping angle of the needle handle 210 needs to be adjusted again, the needle handle 210 can be directly rotated to realize rapid adjustment under the state that the puncture needle 200 is clamped, so that the clamping of the puncture needle 200 is rapid and efficient. Meanwhile, the positioning of the puncture needle 200 is accurate due to the convenience in adjustment, which is beneficial to improving the accuracy of the test result.

In step S100, by pressing one end of the operating member 50, the other end of the operating member 50 is tilted to abut against a side surface of the clamping member 20 facing the base 10, so as to be lifted and separated from the fixing position 11. Thus, the lancet checking fixture 100 is conveniently opened, and the convenience of clamping the lancet 200 is improved.

Further, the step of S200 and adjusting the clamping angle of the needle handle 210 includes: the needle handle 210 is rotated so that the bent handle 220 on the lancet 200 can be inserted into the corresponding positioning slot 41 on the positioning member 40. Therefore, the bent handle 220 is positioned by the preset positioning groove 41, so that the clamping angle of the needle handle 210 is rapidly and accurately positioned, and the inspection efficiency is improved.
