Detailed Implementation

[0032] In the description of this invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the indicated position or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0033] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0034] like Figures 1-8 As shown, the present invention discloses a precision fine-tuning triangular base, including a base body 10, and a plurality of sliders 20, a plurality of adjustment mechanisms 30, and a plurality of locking mechanisms 40 disposed on the base body 10.

[0035] Several sliders 20 are spaced apart on the base body 10 in the vertical direction, and the sliders 20 are slidably disposed on the base body 10.

[0036] The adjustment mechanism 30 corresponds one-to-one with the slider 20. The adjustment mechanism 30 has a reset member 31 and an adjustment screw 32. The adjustment screw 32 is threadedly connected to the base body 10. The cooperation between the adjustment screw 32 and the reset member 31 can adjust the position of the slider 20 relative to the base body 10.

[0037] Specifically, one end of the adjusting screw 32 has a tapered portion 321, and the circumferential outer wall of the tapered portion 321 forms a tapered surface (not shown). The slider 20 is provided with an inclined surface 21, which fits and abuts against the tapered surface. The axial direction of the adjusting screw 32 is perpendicular to the movement direction of the slider 20 (the axial direction of the adjusting screw 32 is defined as the front-back direction). The tapered portion 321 of the adjusting screw 32 pushes the slider 20, causing the slider 20 to move downward. The reset member 31 keeps the slider 20 moving upward. The reset member 31 is a pressure spring or a tension spring. The base body 10 is provided with limiting screws 11 that correspond one-to-one with the slider 20. When the slider 20 abuts against the limiting screw 11, the slider 20 stops moving upward. The tapered portion 321, the inclined surface 21, the reset member 31, and the limiting screw 11 are all existing mature technologies.

[0038] The locking mechanism 40 corresponds one-to-one with the adjusting screw 32. The locking mechanism 40 is located between the adjusting screw 32 and the base body 10. The locking mechanism 40 has an annular part 41 and a limiting part 42. The annular part 41 surrounds the adjusting screw 32. The central axis of the annular part 41 is coaxial with the central axis of the adjusting screw 32. The annular part 41 has several circumferentially evenly distributed locking portions 411. The length direction of the locking portion 411 is parallel to the axial direction of the adjusting screw 32. The limiting part 42 is movably locked with the locking portion 411 so that the adjusting screw 32 has several positions in its rotation direction. The positions correspond one-to-one with the locking portions 411. When the adjusting screw 32 rotates from the Nth position to the N+1th position, the adjusting screw 32 moves axially by one unit distance, and one end of the adjusting screw 32 pushes against the slider 20, causing the slider 20 to move by one unit distance.

[0039] The length of a unit distance is 0.01mm, and there are fifty gear positions. When the adjusting screw 32 rotates to the first gear position, the adjusting screw 32 pushes the slider 20, causing the slider 20 to move a distance of 0.01mm. When the adjusting screw 32 rotates to the fiftieth gear position (i.e., the adjusting screw 32 rotates one revolution), the adjusting screw 32 pushes the slider 20, causing the slider 20 to move a distance of 0.5mm. By setting the length of a unit distance to 0.01mm, the minimum adjustment accuracy of the adjusting screw 32 each time is 0.01mm, achieving precise fine-tuning.

[0040] The locking part 411 is a groove, and the movable part 421 on the limiting member 42 is movablely locked in the groove along the radial direction of the annular member 41 so that the adjusting screw 32 is kept in the current position.

[0041] The limiting member 42 is provided on the base body 10, the annular member 41 is provided on the adjusting screw 32, the annular member 41 and the adjusting screw 32 move axially and rotate synchronously, and the groove is provided on the circumferential outer wall surface of the annular member 41.

[0042] The other end of the adjusting screw 32 has a radially outward protruding head 322. The head 322 is integrally formed with the adjusting screw 32. The outer end face of the head 322 has an internal hexagonal groove 3221. The annular part 41 is connected to the head 322. The head 322, the annular part 41 and the adjusting screw 32 move axially and rotate synchronously.

[0043] On the base body 10 and the head 322, one is provided with a plurality of circularly distributed scales 3222, and the other is provided with a reading mark 12 corresponding to the scales 3222. The scales 3222 correspond one-to-one with the gear positions. For example, the scales 3222 are set on the head 322, and the reading mark 12 is set on the base body 10. In use, when the head 322 is rotated, the scales 3222 follow the rotation of the head 322, and the scale 3222 aligned with the reading mark 12 is the current gear position of the adjusting screw 32.

[0044] The base body 10 is provided with a connected receiving groove 13 and a first mounting hole 14. The annular member 41 and the adjusting screw 32 are both axially movable in the receiving groove 13. One side of the receiving groove 13 is open to form a clearance opening 131, which allows the adjusting screw 32 and the annular member 41 to extend axially. The end of the first mounting hole 14 away from the receiving groove 13 penetrates the outer wall of the base body 10. The limiting member 42 is provided in the first mounting hole 14. The movable part 421 extends into the receiving groove 13 and is movably engaged with the groove.

[0045] The groove is an arc-shaped groove or a V-shaped groove, preferably an arc-shaped groove with an arc-shaped cross-section, and the V-shaped groove with a V-shaped cross-section.

[0046] A ridge 412 is formed between two adjacent grooves. The ridge 412 protrudes radially from the annular member 41 and extends axially from the adjusting screw 32. Each ridge 412 has an arc-shaped guide surface 413 on the side near the groove. By having an arc-shaped guide surface 413 on the side of the ridge 412 near the groove, the moving part can move back and forth stably and smoothly between adjacent grooves when the adjusting screw 32 drives the annular member 41 to rotate, thus achieving stable and smooth adjustment of the adjusting screw 32.

[0047] The limiting member 42 is a ball screw, the movable part 421 is a movable steel ball, and a thrust spring 422 is provided inside the ball screw. The two ends of the thrust spring 422 abut against the ball screw and the movable steel ball, respectively. The movable steel ball can extend and retract along the axial direction of the ball screw. The axial direction of the ball screw is parallel to the radial direction of the annular part 41. When the adjusting screw 32 rotates relative to the base body 10, the movable steel ball rolls relative to the annular part 41. When the adjusting screw 32 is stationary relative to the base body 10, the circumferential outer wall surface of the movable steel ball fits against the inner wall surface of the arc-shaped groove. By setting the groove to an arc-shaped groove, and... The limiting component 42 is a ball screw, and the movable part 421 is a movable steel ball. The elastic action of the thrust spring 422 inside the ball screw on the movable steel ball is used to achieve the movable steel ball engaging with the arc-shaped groove. When the adjusting screw 32 rotates relative to the base body 10, the movable steel ball rolls relative to the annular part 41, so that the wear between the movable steel ball and the annular part 41 is small, thus maintaining the fitting accuracy between the movable steel ball and the arc-shaped groove. When the adjusting screw 32 is stationary relative to the base body 10, the circumferential outer wall surface of the movable steel ball fits against the inner wall surface of the arc-shaped groove, thus restricting the free rotation of the adjusting screw 32 and ensuring the accuracy of the adjusting screw 32 at any position.

[0048] The depth h of the arc-shaped groove along the radial direction of the annular part 41 is less than 1 / 2 of the radius of the movable steel ball. By setting the depth h of the arc-shaped groove along the radial direction of the annular part 41 to be less than 1 / 2 of the radius of the movable steel ball, when the annular part 41 is rotated, the movable steel ball can smoothly disengage from the current arc-shaped groove and be inserted into the next arc-shaped groove, further improving the stability and smoothness of the adjustment screw 32.

[0049] The ball screw is threaded into the first mounting hole 14. By setting the ball screw to be threaded into the first mounting hole 14, the tightness of the fit between the movable steel ball and the arc-shaped groove can be adjusted by rotating the ball screw into the first mounting hole 14. This ensures that the operator is comfortable when rotating the adjusting screw 32 with the required force, and prevents the adjusting screw 32 from rotating freely, so that the adjusting screw 32 maintains accuracy in the current gear position.

[0050] The adjustment mechanism 30 also includes a sleeve 33, which is detachably disposed in the receiving groove 13. The sleeve 33 has a threaded hole 331, and the adjustment screw 32 is threadedly connected to the threaded hole 331.

[0051] The base body 10 is provided with a second mounting hole 15 communicating with the receiving groove 13. The end of the second mounting hole 15 away from the receiving groove 13 penetrates the outer wall of the base body 10. The second mounting hole 15 and the first mounting hole 14 are located on the same side of the base body 10. A fastening screw 16 is threaded into the second mounting hole 15. The axial direction of the fastening screw 16 is parallel to the radial direction of the sleeve 33. The fastening screw 16 abuts against the circumferential outer wall surface of the sleeve 33 to press the sleeve 33 into the receiving groove 13. When disassembling, the fastening screw 16 is loosened, and the sleeve 33 can be moved out from the clearance opening 131. By setting the fastening screw 16 to press the sleeve 33 into the receiving groove 13 in an abutting manner, the sleeve 33 is easy to install and can be easily removed from the receiving groove 13 by loosening the fastening screw 16.

[0052] The sleeve 33 is also provided with a guide hole 332, which is connected to and coaxially arranged with the threaded hole 331. One end of the adjusting screw 32 extends axially with a guide rod 323, which is movably inserted into the guide hole 332. The inner circumferential wall surface of the guide hole 332 and the outer circumferential wall surface of the guide rod 323 are both smooth surfaces. One end of the guide rod 323 has the tapered portion 321. By providing the guide hole 332 and the guide rod 323, and by ensuring that the inner circumferential wall surface of the guide hole 332 and the outer circumferential wall surface of the guide rod 323 are both smooth surfaces, the guide hole 332 provides precise guidance and positioning for the guide rod 323. Thus, during the rotational and axial movement of the guide rod 323 driven by the adjusting screw 32, the precise cooperation between the guide rod 323 and the guide hole 332 further enables the adjusting screw 32 to precisely adjust the slider 20.

[0053] The sleeve 33 extends axially to form a connecting ring 333 near the annular member 41. The threaded hole 331 is provided on the connecting ring 333. The annular member 41 is sleeved on the connecting ring 333. An anti-detachment structure 34 is provided between the connecting ring 333 and the annular member 41. The anti-detachment structure 34 restricts the annular member 41 from detaching from the connecting ring 333.

[0054] The anti-detachment structure 34 has a first annular groove 341, a second annular groove 342, and a retaining spring 343. The first annular groove 341 is recessed in the circumferential inner wall of the annular member 41, and the second annular groove 342 is recessed in the circumferential outer wall of the connecting ring 333. The second annular groove 342 extends along the axial direction of the adjusting screw 32. The retaining spring 343 is sleeved on the outside of the connecting ring 333. The outer edge of the retaining spring 343 is located in the first annular groove 341, and the inner edge of the retaining spring 343 is located in the second annular groove 342. In the groove 342, the cross-section of the retaining spring 343 is circular. The retaining spring 343 is a C-shaped retaining spring 343. During assembly and disassembly, the elastic contraction and expansion characteristics of the C-shaped retaining spring 343 can be used to install the C-shaped retaining spring 343 between the first annular groove 341 and the second annular groove 342, or to disassemble the retaining spring 343 from the first annular groove 341 and the second annular groove 342. It can be understood that the first annular groove 341 can also be set to extend along the axial direction of the adjusting screw 32.

[0055] It should be noted that the snap-fit ​​part 411 can also be set as a protrusion, and a corresponding recess is provided on the limiting member 42 to cooperate with the protrusion; the limiting member 42 can also be provided on the adjusting screw 32, and when the annular member 41 is set on the base body 10, the groove is provided on the circumferential inner wall surface of the annular member 41.

[0056] The present invention also discloses a circular loom (not shown) including the aforementioned precision fine-tuning triangle.

[0057] The adjustment process of this invention is as follows: When the head 322 is rotated forward, the head 322, adjusting screw 32, ring part 41, and scale 3222 rotate synchronously and move synchronously towards the slider 20 along the axial direction of the adjusting screw 32. The adjusting screw 32 drives the guide rod 323 to move synchronously, so that the conical part 321 pushes against the inclined surface 21 on the slider 20, and the slider 20 moves down. At the same time, the ring part 41 rotates relative to the movable part 421 and the connecting ring 333. The movable part 421 is movably engaged with the locking part 411. The scale 3222 aligned with the reading mark 12 is the current position of the adjusting screw 32. When the adjusting screw 32 rotates to the first position, the adjusting screw 32 pushes against the slider 20, causing the slider 20 to move a distance of 0.01mm. Similarly, when the adjusting screw 32 rotates to the fiftieth position, the adjusting screw 32 pushes against the slider 20, causing the slider 20 to move a distance of 0.5mm.

[0058] When the head 322 is rotated in the opposite direction, the slider 20 slides upward under the action of the reset member 31.

[0059] In summary, this invention provides a locking mechanism 40 between the adjusting screw 32 and the base body 10. The locking mechanism 40 has an annular member 41 and a limiting member 42. The annular member 41 surrounds the adjusting screw 32 and has several circumferentially evenly distributed locking portions 411. The length direction of the locking portions 411 is parallel to the axial direction of the adjusting screw 32. The limiting member 42 is movably locked with the locking portions 411, so that the adjusting screw 32 has several positions in its rotation direction. Each position corresponds to a locking portion 411. When the adjusting screw 32 rotates from the Nth position to the N+1th position, one end of the adjusting screw 32 pushes against the slider 20, causing the slider 20 to move a unit distance. The smaller the set unit distance, the higher the adjustment accuracy, thereby achieving higher adjustment accuracy of the slider 20. The adjusting screw 32 can be rotated to any position to obtain a corresponding and unique adjustment result, making the adjustment fast and efficient.

[0060] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc., made to the above embodiments based on the actual technology of the present invention shall still fall within the scope of the technical solution of the present invention.
