Description

Technical Field

[0001] The present invention relates to the technical field of optical debugging, and in particular to an adjustment lens frame for laser equipment. Background Art

[0002] The position of lenses within a laser's optical cavity significantly impacts the quality of the output beam. Deviations in lens position can directly alter the optical path, resulting in suboptimal laser beam quality and even component damage. During laser optical path commissioning, some lenses and components must be flexible enough to accommodate complex optical systems. Furthermore, as industrial equipment, the fixed optical cavity must remain stable and reliable, preventing any sluggish position changes to maintain optimal performance.

[0003] The traditional fixed laser lens adjustment frame is fixed with screws and is adjusted by adding metal sheets or grinding under the screws. It has a compact structure, but cannot achieve continuous adjustment. It is necessary to repeatedly change the thickness of the metal sheet or the amount of grinding to find the best angle, which is a lot of work and complicated to operate. Most of the optical adjustment frames purchased on the market are laboratory supplies with poor stability. They cannot adapt to transportation, impact and other environments and cannot be used in actual engineering production. Some adjustable frames use motors to control pitch and azimuth, which can be fixed and locked, and have high adjustment accuracy, but they often take up a large space and do not meet the requirements of compact structure and small size of the equipment. Summary of the Invention

[0004] In order to solve the above problems, the present invention provides an adjustment frame for laser equipment, which can realize continuous fine-tuning of the pitch direction of the lens, ensure that the structures are always in close contact during the adjustment process, and the adjusted frame structure is fixed, and the optical path is stable and reliable.

[0016] Furthermore, it also includes a slit, which is arranged on the side of the vertical plate opposite to the pushing assembly, connected to the special-shaped pin hole, extending through the front and rear sides of the vertical plate to divide the vertical plate into an upper section and a lower section, and the upper section is pressed down to achieve special-shaped pin locking.

[0017] Furthermore, an annular plate is provided on the side of the vertical plate close to the lens assembly. The annular plate extends out of the side of the vertical plate, and the special-shaped pins are sequentially inserted into the annular plate and the special-shaped pin holes.

[0018] Furthermore, a knob centering hole and an annular hole are provided on the knob, and the annular hole takes the knob centering hole as the center of a circle. A sleeve shaft is formed between the knob centering hole and the annular hole, and a torsion spring is sleeved on the outside of the sleeve shaft. A first elastic pin is provided on the vertical plate, and the first elastic pin is extended into the annular hole. A second elastic pin is inserted into the annular hole in the knob, and one end of the torsion spring is pressed against the inner side of the first elastic pin, and the other end is hooked around the outer side of the second elastic pin.

[0019] Furthermore, the knob is connected to the special-shaped pin through a centering screw, and a special-shaped pin centering hole is provided along the center axis of the special-shaped pin. The centering screw passes through the knob centering hole and the special-shaped pin centering hole in sequence.

[0020] Furthermore, a pushing hole is provided on the vertical plate, which is connected to the special-shaped pin hole. The pushing assembly is located in the pushing hole. The pushing assembly includes a pressure adjusting pin, a compression spring and a spherical body connected in sequence. The compression spring sleeve is placed on the outside of the pressure adjusting pin stud, and the end portion is against the spherical body. A notch is provided on the peripheral wall of the annular special-shaped pin body, and the spherical body rotates and presses against the notch.

[0021] Furthermore, an upper locking hole is provided on the upper section of the slit partition, and a lower locking hole is provided on the lower section opposite to the upper locking hole. The locking screw passes through the upper locking hole, the slit and the lower locking hole in sequence, and a locking spring and a gasket are successively mounted on the stud of the locking screw. The gasket is located on the surface of the upper section, and the locking spring presses against the surface of the gasket.

[0022] Furthermore, a press-turn thread pair hole is provided on the horizontal plate, and the central axis of the press-turn thread pair hole is located beside the central axis of the special-shaped pin hole. The press-turn thread pair includes a fine-thread screw and a screw sleeve placed on the outside of the fine-thread screw. The screw sleeve is located in the press-turn thread pair hole, and the fine-thread screw is threadedly connected to the screw sleeve. The end of the fine-thread screw is a spherical structure, extending out of the horizontal plate to press against the lens seat.

[0023] Furthermore, a centering pin hole and an arc-shaped hole are provided on the horizontal seat. The centering pin is inserted into the centering pin hole. The arc-shaped hole is located around the centering pin hole. A positioning screw is detachably connected in the arc-shaped hole. The lens seat is sequentially embedded with a pressure ring and a gasket, and the lens is installed in the gasket.

[0024] The adjusting mirror frame for laser equipment of the present invention has the following beneficial effects:

[0025] 1. The present invention maintains the lens center during pitch adjustment. A shaped pin is inserted into a shaped pin hole on the riser, with the pin's central axis passing through the lens center. This allows the shaped pin to act as a pitch adjustment axis, maintaining the lens center during pitch adjustment.

[0026] 2. The present invention realizes continuous fine-tuning of the lens pitch. The central axis of the pressure-turn thread pair hole provided on the horizontal plate is located beside the central axis of the special-shaped pin hole. When the pressure-turn thread pair inserted into the pressure-turn thread pair hole is rotated and pressed down, its point of action is the lens seat beside the central axis of the special-shaped pin, which can bias the lens seat in a biasing manner, so that the lens seat rotates and realizes the lens pitch adjustment. In particular, the lens pitch adjustment can maintain continuous fine-tuning and can also make the lens seat always in close contact with the pressure-turn thread pair: specifically, the knob is connected to the special-shaped pin through a centering screw nail, and a torsion spring is installed inside the knob. One end of the torsion spring presses against the inner side of the first elastic pin on the vertical plate, and the other end is hooked around the outer side of the second elastic pin provided through the knob. In actual use, the knob will be rotated first to press against the torsion spring to form a certain pre-tightening force, and then the centering screw nail is inserted to connect the knob to the special-shaped pin. When the pressure-turn thread pair is rotated downward, the biased lens rotates, driving the special-shaped pin, centering screw, and knob to rotate with it. The knob continues to press against the torsion spring, which generates a continuous and stable rebound reaction force, pushing the lens holder to always keep close contact with the pressure-turn thread pair. When the pressure-turn thread pair is rotated upward, the rebound reaction force of the torsion spring causes the lens holder to rotate in the opposite direction. Throughout the entire reversal process, the lens holder remains in close contact with the pressure-turn thread pair, thereby achieving close and continuous fine-tuning of the lens pitch.

[0027] 3. The present invention's push assembly consists of a pressure-adjusting pin, a compression spring, and a spherical body, which abuts the shaped pin. This contact pattern of the spherical body's arcuate surface prevents optical path position shifts caused by creep during metal point contact. Furthermore, the pressure-adjusting pin is pressed against the spherical body by the compression spring, which in turn abuts the shaped pin. The spring's flexible, cushioning properties ensure that the spherical body maintains a firm, flexible contact with the shaped pin, preventing structural wobbling and pitch axis position shifting during pitch adjustment.

[0028] 4. The present invention's special-shaped pin is a cylindrical structure with a notch on the pin's circumferential wall, and a spherical body abuts against the notch. The inclined notch facilitates the snap-fitting and accommodating of the spherical body. Furthermore, compared to a straight pin with a spherical body directly contacting the pin, which generates only a vertical force directed toward the pin, the inclined notch decomposes the downward pressure into horizontal and vertical forces. This not only vertically pushes the pin to secure it, but also ensures close horizontal contact between the pin and adjacent components.

[0029] 5. In the present invention, an annular plate is provided on the side of the vertical plate close to the lens assembly. The annular plate extends out of the side of the vertical plate, and the portion directly in contact with the lens seat is the protruding annular plate, so that the lens seat and the vertical plate are more closely attached.

[0030] 6. The present invention provides a slit on the side of the riser opposite the push assembly. This slit connects to the special-shaped pin hole and extends through the front and rear sides of the riser, dividing the riser into an upper section and a lower section. A locking screw is provided, sequentially passing through the upper section, the slit, and the lower section. Turning the locking screw presses down the upper section, narrowing the gap in the slit and completing the surrounding locking of the special-shaped pin.

[0031] 7. In the present invention, the cross seat is sleeved on the outside of the centering pin, and the central axis of the centering pin passes through the center of the lens. The movement of the cross seat with the centering pin as the center is equivalent to the movement with the center of the lens as the center. The center of the lens remains unchanged during the orientation adjustment process. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0044] In order to better understand the purpose, structure and function of the present invention, the following is a further detailed description of an adjustment mirror frame for laser equipment of the present invention in conjunction with the accompanying drawings.

[0045] like Figure 1-9 As shown, an adjustment lens frame for laser equipment includes a centering pin 1, a horizontal seat 2, a vertical seat 3, a lens assembly 4, a knob assembly 5, a pressing thread pair 6, a pushing assembly 7, etc., wherein:

[0046] The centering nail 1 can be fixedly arranged on the operating table. The horizontal seat 2 is sleeved on the outside of the centering nail 1.

[0047] Furthermore, the horizontal base 2 is provided with a centering pin hole 21 and an arc-shaped hole 22. The centering pin 1 is inserted into the centering pin hole 21, and the arc-shaped hole 22 is located around the centering pin hole 21. The arc-shaped hole 22 is detachably connected to the arc-shaped hole 22. The horizontal base 2 rotates around the centering pin 4 to adjust the orientation of the lens 411. The central axis of the centering pin 1 passes through the center of the lens 411. This ensures that the center of the lens 411 remains unchanged during the rotation of the horizontal base 2, and the optical path does not change. When the horizontal base 2 is rotated into position, the set screw in the arc-shaped hole 22 is tightened to securely fix the adjusted lens 411.

[0048] Furthermore, the vertical seat 3 is formed by connecting a vertical plate 31 and a horizontal plate 32 . The vertical plate 31 is connected to the horizontal seat 2 . A special-shaped pin hole 311 is provided on the vertical plate 31 .

[0049] Furthermore, the vertical plate 31 is vertically connected to the horizontal plate 32 to form a T-shaped structure. The vertical plate 31 is vertically connected to the horizontal seat 2, and the horizontal plate 32 is parallel to the horizontal seat 2; the special-shaped pin hole 311 on the vertical plate 31 is arranged horizontally.

[0050] Furthermore, the lens assembly 4 is formed by connecting a lens seat 41 and a special-shaped pin 42. The special-shaped pin 42 is located at the end of the lens seat 41. The central axis of the special-shaped pin 42 passes through the center of the lens 411. The special-shaped pin 42 is inserted into the special-shaped pin hole 311.

[0051] Furthermore, a lens 411 is installed in the lens holder 41. More specifically, a pressure ring 412 and a gasket 413 are sequentially embedded in the lens holder 41. The lens 411 is installed in the gasket 413, so that the installation and connection of the lens 411 are more stable. In addition, the lens 411 can also rotate around its center.

[0052] Furthermore, an annular plate 9 is provided on the side of the riser 31 adjacent to the lens assembly 4. The annular plate 9 extends beyond the side of the riser 31, and a shaped pin 42 is sequentially inserted through the annular plate 9 and the shaped pin hole 311. When the shaped pin 42 is connected to the riser 31, the lens holder 41 connected to the shaped pin 42 directly abuts against the protruding annular plate 9, achieving a closer contact.

[0053] Furthermore, the knob assembly 5 is attached to the side of the vertical plate 31 opposite to the lens assembly 4, and consists of a knob 51 and a torsion spring 52. The knob 51 is connected to the special-shaped pin 42, and the torsion spring 52 is sleeved inside the knob 51, with its two ends respectively connected to the vertical plate 31 and the knob 51.

[0054] Furthermore, the knob 51 is a horizontal, concave-shaped structure. It is provided with a knob centering hole 511 and an annular hole 512. The annular hole 512 is centered around the knob centering hole 511. A sleeve shaft 513 is formed between the knob centering hole 511 and the annular hole 512. The torsion spring 52 is sleeved on the outside of the sleeve shaft 513. The vertical plate 31 is provided with a first elastic pin 314, which extends into the annular hole 512. The knob 51 is penetrated by a second elastic pin 53, which extends into the annular hole 512. One end of the torsion spring 52 abuts against the inside of the first elastic pin 314, while the other end is hooked around the outside of the second elastic pin 53. When the knob 51 is rotated, the second elastic pin 53 rotates with the knob 51, thereby pushing the end of the torsion spring 52 hooked around the outside of the second elastic pin 53, causing the torsion spring 52 to twist.

[0055] Furthermore, the knob 51 is connected to the special-shaped pin 42 through a centering screw 54. A special-shaped pin centering hole 421 is provided along the central axis of the special-shaped pin 42. The centering screw 54 passes through the knob centering hole 511 and the special-shaped pin centering hole 421 in sequence to fix the knob 51 to the special-shaped pin 42.

[0056] Furthermore, the thread pair 6 is pressed and turned, passes through the horizontal plate 32 , and presses against the lens holder 41 , with the pressing position being located beside the central axis of the special-shaped pin 42 .

[0057] More specifically, the horizontal plate 32 is provided with a press-turn thread pair hole 321, into which the press-turn thread pair 6 is mounted. The central axis of the press-turn thread pair hole 321 is located to the side of the central axis of the shaped pin hole 311. This ensures that the point of pressure applied by the press-turn thread pair 6 against the lens holder 41 is located to the side of the central axis of the shaped pin 42, biasing the lens holder 41 and enabling rotation of the lens holder 41.

[0058] Furthermore, the pressed-turn thread pair 6 includes a fine-pitch screw 61 and a screw sleeve 62 placed on the outside of the fine-pitch screw 61. The screw sleeve 62 is located in the pressed-turn thread pair hole 321. The fine-pitch screw 61 is threadedly connected to the screw sleeve 62. The fine-pitch screw 61 extends out of the horizontal plate 32 and presses against the lens seat 41. The end of the fine-pitch screw 61 is a spherical structure and is in point contact with the lens seat 41, which facilitates the rotation of the lens seat 41 during the adjustment process.

[0059] Furthermore, the pushing assembly 7 is placed on one side of the vertical plate 31 and presses against the special-shaped pin 42 .

[0060] Furthermore, a pushing hole 315 is provided on the vertical plate 31, and the pushing hole 315 is connected to the special-shaped pin hole 311. The pushing assembly 7 is located in the pushing hole 315. The pushing assembly 7 includes a pressure adjustment pin 71, a compression spring 72 and a spherical body 73 connected in sequence. The compression spring 72 is placed on the outside of the stud of the pressure adjustment pin 71, and the end thereof presses against the spherical body 73. The spherical body 73 rotates to press against the special-shaped pin 42.

[0061] Furthermore, a notch 422 is provided on the peripheral wall of the annular shaped pin 42, and the spherical body 73 rotates and presses against the notch 422. The notch 422 is a V-shaped structure, but due to processing errors, this V-shaped structure is usually asymmetrical. After the shaped pin 42 is inserted into the shaped pin hole 311, the spherical body 73 is inserted into the push hole 315, and can contact the inclined surface on one side of the V-shaped structure, leaving a gap on the other side. After the pressure adjustment pin 11 is screwed in, the spherical body 73 is pressed tightly against the inclined surface of the notch 422 of the shaped pin 42. Under the action of the compression spring 72, the spherical body 73 always presses against the inclined surface of the V groove. In addition, vertical and horizontal force components are formed at the contact point, which can not only push the shaped pin 42 pin body vertically to fix it, but also ensure that the shaped pin 42 pin body is in close contact with adjacent components in the horizontal direction, making the entire structure more stable and preventing loosening during the optical path debugging process.

[0062] Furthermore, the slit 8 is arranged on the side of the vertical plate 31 opposite to the pushing assembly 7, connected to the special-shaped pin hole 311, extending through the front and rear sides of the vertical plate 31 to divide the vertical plate 31 into an upper section 312 and a lower section 313, and the upper section 312 is pressed down to lock the special-shaped pin 42.

[0063] Furthermore, an upper locking hole is provided on the upper section 312 divided by the slit 8, and a lower locking hole is provided on the lower section 313 opposite the upper locking hole. The locking screw 316 passes through the upper locking hole, the slit 8 and the lower locking hole in sequence. The locking spring 316a and the gasket 316b are sequentially mounted on the stud of the locking screw 316. The gasket 316b is located on the surface of the upper section 312, and the locking spring 316a is pressed against the surface of the gasket 316b.

[0064] The working process of the adjustment mirror frame for laser equipment of the present invention is described below with reference to the accompanying drawings:

[0065] Azimuth adjustment: Loosen the positioning screw, rotate the horizontal seat 2 to the desired position, and then tighten the positioning screw to complete the orientation adjustment.

[0066] Pitch Adjustment: Insert the shaped pin 42 into the shaped pin hole 311. Rotate the knob 51 to press against the torsion spring 52 to create a preload. Screw the centering screw 54 into the knob centering hole 511 and the shaped pin centering hole 421 to secure the knob 51 to the shaped pin 42. Insert the spherical body 73 into the push hole 315 and tighten the pressure adjustment screw 71 until the spherical body 73 is in close contact with the shaped pin 42. The pressure-rotating threaded pair 6 is rotated downward, causing the bias lens 411 to rotate, driving the shaped pin 42, centering screw 54, and knob 51 to rotate with it. The knob 51 continues to press against the torsion spring 52. The spring reaction force generated by the torsion spring 52 ensures that the lens holder 41 is always in close contact with the pressure-rotating threaded pair 3. The pressure-rotating threaded pair 6 is rotated upward, causing the lens holder 41 to rotate in the opposite direction. The spring reaction force of the torsion spring 52 ensures that the lens holder 41 is always in close contact with the pressure-rotating threaded pair 3 during the reverse rotation. The locking screw 316 is rotated downward to press the upper section 312, reducing the gap in the slit 8 and locking the shaped pin 42, completing the fixation after the pitch adjustment.

[0067] The present invention is further described below with the aid of specific embodiments. However, it should be understood that the specific description herein should not be construed as limiting the essence and scope of the present invention.
