Description

Technical Field

[0001] The utility model relates to the technical field of optical experimental equipment, and particularly relates to an industrial six-axis optical adjustment frame. Background Art

[0002] In various optical experiments or application scenarios, it is necessary to assemble and build optical elements to form an optical system. And in the built optical system, in order to obtain better imaging effects, an optical adjustment frame is required to support and adjust the optical elements in the optical system, so as to realize the adjustment of the optical elements in one or more directions of the X-axis, Y-axis or Z-axis.

[0003] CN201910438369.3 discloses a cage-type five-axis optical adjustment frame, which includes an adjustment frame bracket, two indexing heads, four hooked tension springs and eight internal hexagonal set screws, etc. Among them, the two indexing heads are used to realize the horizontal movement and vertical movement of the adjustment frame slider, so as to drive the lens to move and realize the adjustment of the horizontal position and vertical position of the lens; two hooked tension springs are used to horizontally hook the internal hexagonal screws on the adjustment frame slider and the internal hexagonal set screws assembled on the adjustment frame bracket, and the other two hooked tension springs are used to vertically hook the internal hexagonal screws on the adjustment frame slider and the internal hexagonal set screws assembled on the adjustment frame bracket. This kind of lens frame reduces the difficulty, cycle and connecting rod purchase cost of the user in building the optical system. When building the optical system, multiple cage-type five-axis optical adjustment frames are combined and connected to realize multiple turns of the optical path in up to three mutually perpendicular directions.

[0004] When using the above-mentioned optical adjustment frame to adjust the positions of the optical elements in the X-axis (horizontal direction) and Y-axis (vertical direction), not only is it necessary to use the indexing head for adjustment, but also it is necessary to use the hooked tension springs arranged near the indexing head and connected between the slider and the adjustment frame bracket. Only under the pushing of the indexing head and the return action of the hooked tension springs can the fine adjustment of the positions of the optical elements in the horizontal direction (X-axis) and vertical direction (Y-axis) be realized. However, after long-term use, the load and stability borne by the hooked tension springs are relatively low, and when used under working conditions of high vibration and high load, the stability of the optical adjustment frame will be even lower, greatly reducing the adjustment accuracy of the optical elements and the applicable range of the optical adjustment frame.

[0005] Therefore, there is an urgent need to provide an optical adjustment frame with high stability and a wider applicable range to solve the above technical problems. Summary of the Utility Model

[0006] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide an industrial six-axis optical adjustment frame with a simple structure and high stability.

A gland is provided on one side of the base close to the substrate, and a floating ring is installed inside it. First and second thread pairs for driving the floating ring to move along the X-axis and Y-axis are respectively installed on two adjacent side walls of the gland. Third, fourth, and fifth thread pairs for pushing the base to move towards the substrate relative to the substrate are installed on the substrate. I-shaped grooves extending inward are formed on both sides of the floating ring close to the first and second thread pairs, and guide blocks are connected to both sides of the floating ring far from the first and second thread pairs. Guide grooves matching the guide blocks are formed on both sides of the base far from the first and second thread pairs. Protrusions are provided at the tails of the first and second thread pairs, and the protrusions extend into the base and are clamped in the I-shaped grooves.

[0008] Further, the base includes two driving frames, two guiding frames, and a bottom plate provided at the bottom. The two driving frames are used to install the first and second thread pairs, and they are sequentially connected to the two guiding frames to form a square frame of the base. A sunken platform is also provided between the direction frame and the bottom plate, and through holes are formed on the bottom plate.

The cross-section of the guide block is U-shaped, and its two vertical sides are clamped in the guide grooves, and a cylindrical compression spring is installed between its horizontal side and the inner side wall of the sunken platform.

[0010] Further, mounting holes are formed at the four corners of the floating ring, and a top-tightening steel ball assembly is installed in the mounting holes.

[0011] Further, the top-tightening steel ball assembly includes a first set screw, a tension spring, and a top-tightening steel ball. The first set screw is detachably installed in the mounting hole. One end of the tension spring is connected to the inner wall of the first set screw, and the other end is connected to the top-tightening steel ball. Part of the top-tightening steel ball is exposed outside the floating ring.

[0012] Further, the substrate is of an L-shaped structure, and its vertical side and horizontal side are elastically connected to the base through a tension spring assembly. The third and fourth thread pairs are respectively installed at the corners of the vertical side and horizontal side of the substrate, and the fifth thread pair is installed at the connection of the vertical side and horizontal side of the substrate.

[0013] Further, the tension spring assembly includes a second set screw, a return spring, a fixing pin, and a pull ring connected to the fixing pin. The head of the return spring is connected to the pull ring, and it is sleeved on the second set screw.

[0014] Further, a limiting hole and a limiting groove that communicate with each other are formed in the substrate. The pull ring is located in the limiting hole, and both ends of the fixing pin are lapped in the limiting groove. A countersunk hole is formed in the position of the base corresponding to the limiting hole. The second set screw penetrates through the bottom plate and is screwed into the countersunk hole. The tail of the return spring is connected to the countersunk table of the countersunk hole.

[0015] Further, the bronze bushes of the third thread pair, the fourth thread pair, and the fifth thread pair are connected to the substrate by third set screws. The tails of the third thread pair, the fourth thread pair, and the fifth thread pair all pass through the substrate and abut against the base.

[0016] Further, a pair of V-shaped grooves are symmetrically formed on the bronze bushes of the third thread pair, the fourth thread pair, and the fifth thread pair.

By providing an I-shaped groove on the outer side wall of the floating ring, and providing bosses clamped in the I-shaped groove at the tails of the first thread pair and the second thread pair, when it is necessary to move the floating ring in the X-axis or Y-axis direction, the position of the floating ring in the X-axis or Y-axis can be adjusted by screwing the first thread pair or the second thread pair inward; when it is necessary to move the floating ring in the opposite direction of the X-axis or Y-axis or reset it, only need to screw out the first thread pair or the second thread pair outward to drive the floating ring to move or reset in the opposite direction of the X-axis or Y-axis; this structure adopts a rigid connection method between the floating ring and the first thread pair and the second thread pair, and can directly pull the entire floating ring to move through the first thread pair and the second thread pair. Compared with the traditional adjustment bracket for X and Y direction movement with spring return, the angle offset value of the adjustment bracket is greatly reduced, the stability and load capacity of the overall structure are effectively enhanced, and the adjustment accuracy of the optical element is improved.

Detailed implementation manners

[0031] The following further illustrates the present utility model in conjunction with the accompanying drawings and embodiments, but these specific implementation manners do not limit the protection scope of the present utility model in any way.

[0032] Embodiment 1

[0033] See Figures 1-10, An industrial six-axis optical adjustment mount, comprising a base, a gland 2 and a substrate 3. The substrate 3 is arranged behind the base. The gland 2 is covered on one side of the base close to the substrate 3 and is detachably connected to the substrate 3 by countersunk head screws.

[0034] A floating ring 11 is installed inside the base, and it includes two integrally formed driving frames (specifically, a first driving frame 12 and a second driving frame 13), two guiding frames (specifically, a first guiding frame 14 and a second guiding frame 15) and a bottom plate 16. The first driving frame 12, the second driving frame 13, the first guiding frame 14 and the second guiding frame 15 are connected end to end and sequentially to form a square frame of the base. The bottom plate 16 is located at the bottom of the square frame. A counterbore 17 is also provided between the square frame and the bottom plate 16. A through hole 31 is opened at the center of the bottom plate 16. The floating ring 11 is installed in the counterbore 17. An avoidance hole 18 communicating with the through hole 31 is provided in the middle of the gland 2.

[0035] A connecting sleeve 19 is also connected to the inner side of the floating ring 11. The front end of the connecting sleeve 19 extends away from the gland 2 to the outside of the floating ring 11, and a part extending to the outside of the floating ring 11 is detachably connected with an optical element mounting assembly 4 penetrating through the through hole 31. The detachable connection method can be a threaded connection or a screw connection.

[0036] The optical element mounting assembly 4 in the present utility model only needs to have the function of mounting an optical element on the assembly, such as the Z-axis moving assembly disclosed in CN202322282826.9, a dovetail optical element adjustment mount. A specific structure of the optical element mounting assembly 4 is listed in the present utility model, including an optical element mounting seat 43 with a knurled knob, a connecting seat 44 without a knurled knob, a snap ring 45 and a retaining ring 46. The connecting seat 44 is threadedly connected to the rear end of the optical element mounting seat 43. The retaining ring 46 is installed on the periphery of the optical element mounting seat 43, and it is connected to the optical element mounting seat 43 and the connecting sleeve 19 by screws. The snap ring 45 is threadedly connected to the inside of the optical element. During use, the optical element can be mounted on the mounting seat and fixed by the snap ring 45.

[0037] First thread pairs 5 and second thread pairs 6 are respectively installed on both side walls of the first driving frame 12 and the second driving frame 13. The first thread pair 5 is used to drive the floating ring 11 to move in the X-axis direction to realize the position adjustment in the X-axis direction. The second thread pair 6 is used to drive the floating ring 11 to move in the Y-axis direction to realize the position adjustment in the Y-axis direction.

[0038] Both the screw tails of the first screw pair 5 and the second screw pair 6 are provided with bosses 20. On the side of the floating ring 11 close to the first screw pair 5 and the second screw pair 6, I-shaped grooves 21 extending inwards are respectively formed. And on the side of the floating ring 11 far from the first screw pair 5 and the second screw pair 6, a first guide block 22 and a second guide block 23 are respectively connected. The boss 20 at the tail of the first screw pair 5 and the boss 20 at the tail of the second screw pair 6 respectively pass through the first driving frame 12 and the second driving frame 13 and extend into the base and are clamped in the I-shaped groove 21. The structures of the first guide block 22 and the second guide block 23 are the same.

[0039] The I-shaped groove 21 includes a first groove 32, a second groove 33 and a connecting groove 34 connecting the first groove 32 and the second groove 33. The screw tails of the first screw pair 5 and the second screw pair 6 connected to the boss 20 are both clamped in the second groove 33.

[0040] On the first guide frame 14 and the second guide frame, guide grooves 24 matching the first guide block 22 and the second guide block 23 are respectively formed. And the guide grooves 24 are formed on the side of the counterbore 17 far from the first screw pair 5 and the second screw pair 6. The cross section of the guide block is U-shaped. Its two vertical sides are clamped in the guide groove 24. Its horizontal side abuts against the floating ring 11. And a cylindrical compression spring is installed between the side of its horizontal side far from the floating ring 11 and the inner side wall of the counterbore 17.

[0041] In the utility model, by providing the I-shaped groove 21 on the floating ring 11 and providing the bosses 20 clamped with the I-shaped groove 21 at the tails of the first screw pair 5 and the second screw pair 6, a rigid connection is formed between both the first screw pair 5 and the second screw pair 6 and the floating ring 11. By directly adopting this structure and screwing the first screw pair 5 and the second screw pair 6 inwards or outwards, the first screw pair 5 and the second screw pair 6 directly pull the floating ring 11 to move, so as to realize the position adjustment in the X and Y axis directions. Compared with the adjustment frame for X and Y direction movement with spring return in the prior art, this rigid connection structure can bear a greater load and has stronger long-term stability performance. It is suitable for use under working conditions with high vibration and high load. It not only increases the bearing load and stability of the optical adjustment frame, but also greatly expands the application range of the optical adjustment frame.

[0042] In addition, the utility model is provided with a first guide block 22 and a second guide block 23 connected to the floating ring 11 and clamped with the guide groove 24. When the floating ring 11 is driven to move by the first thread pair 5 and the second thread pair 6 to adjust the X and Y axis positions, since the two vertical parts of the first guide block 22 and the second guide block 23 are clamped in the guide groove 24, when the floating ring 11 moves, the two vertical parts of the first guide block 22 and the second guide block 23 can only move linearly along the X and Y axes in the guide groove 24, thereby pulling the floating ring 11 to move linearly along the X and Y axes, playing a guiding role, and further improving the adjustment accuracy of the optical adjustment frame.

[0043] An opening is provided at the bottom of the I-shaped groove 21, and the opening is located at the second groove 33. The arrangement makes it easy for the floating ring 11 to clamp the boss 20 of the first thread pair 5 and the second thread pair 6 in the I-shaped groove 21 through the opening, thereby facilitating the assembly and disassembly of the floating ring 11 and the first thread pair 5 and the second thread pair 6.

[0044] The four corners of the floating ring 11 are provided with mounting holes 35, and a tightening steel ball 25 assembly is installed in the mounting holes 35. The tightening steel ball 25 assembly includes a first set screw, a tension spring and a tightening steel ball 25. The first set screw is detachably installed in the mounting hole 35 through a threaded connection, one end of the tension spring is connected to the inner wall of the first set screw, and the other end thereof is connected to the tightening steel ball 25. The upper part of the tightening steel ball 25 is exposed outside the floating ring 11. The tightening steel ball 25 assembly is used to eliminate the gap in the Z-axis direction and improve the adjustment accuracy of the optical adjustment frame.

[0045] In order to adjust the pitch / yaw angle of the optical adjustment frame, a third thread pair 7, a fourth thread pair 8 and a fifth thread pair 9 are installed on the base plate 3 for pushing the base to move relative to the base plate 3. The base plate 3 is an L-shaped structure, and its vertical part and horizontal part are elastically connected to the base through multiple tension spring assemblies (specifically 3 in this embodiment), the third thread pair 7 and the fourth thread pair 8 are respectively installed at the corners of the vertical part and the horizontal part of the base plate 3, and the fifth thread pair 9 is installed at the connection between the vertical part and the horizontal part of the base plate 3.

[0046] The tension spring assembly is used for adjustment and resetting in the opposite direction of the third thread pair 7, the fourth thread pair 8 and the fifth thread pair 9, and specifically includes a second set screw 26, a reset spring 27, a fixing pin 28 and a pull ring connected to the fixing pin 28. The head of the reset spring 27 is connected to the pull ring, and it is sleeved on the second set screw 26.

[0047] The substrate 3 is provided with a limiting hole 37 and a limiting groove 38 that communicate with each other. The pull ring is located within the limiting hole 37. Both ends of the fixing pin 28 are lapped within the limiting groove 38. A countersunk hole 39 is provided at a position on the counterbore 17 of the base corresponding to the limiting hole 37. The second set screw 26 passes through the substrate 3 and the bottom plate 16 and is screwed into the countersunk hole 39. The tail of the return spring 27 is connected to the countersunk head of the countersunk hole 39.

[0048] The third thread pair 7, the fourth thread pair 8, and the fifth thread pair 9 have the same structure. The bronze bushings 40 of the third thread pair 7, the fourth thread pair 8, and the fifth thread pair 9 are connected to the substrate 3 by the third set screw 29. This third set screw 29 can improve the connection between the substrate 3 and the third thread pair 7, the fourth thread pair 8, and the fifth thread pair 9, avoiding the phenomenon that the third thread pair 7, the fourth thread pair 8, and the fifth thread pair 9 are pulled under the action of the return spring 27, and improving the stability of the optical adjustment mount. The tails of the third thread pair 7, the fourth thread pair 8, and the fifth thread pair 9 all pass through the substrate 3 and abut against the counterbore 17 of the base, and wear-resistant gaskets 30 are provided at the parts in contact with the counterbore 17. The wear-resistant gaskets 30 can increase the contact strength of the steel balls at the tails of the third thread pair 7, the fourth thread pair 8, and the fifth thread pair 9, preventing part wear from affecting the accuracy.

[0049] A pair of V-shaped grooves 41 are symmetrically provided on the bronze bushings 40 of the third thread pair 7, the fourth thread pair 8, and the fifth thread pair 9. A cylindrical pin is connected to the inner side wall of the lower part of one of the V-shaped grooves 41. An upwardly extending opening groove is provided on the substrate 3 at a position corresponding to the cylindrical pin. The cylindrical pin is clamped within the opening groove. In this solution, by providing the cylindrical pin 42 and the opening groove, the installation position of the third set screw 29 can be positioned when the thread pair, the fourth thread pair 8, and the fifth thread pair 9 are assembled onto the substrate 3, improving the convenience during installation; the setting of the V-shaped grooves 41 can facilitate the extrusion deformation of the bronze bushings 40, improving the service life of the thread pair.

[0050] The working principle of an industrial-grade six-axis optical adjustment mount of the present utility model:

[0051] In the industrial-grade six-axis optical adjustment mount of the present utility model, the first thread pair 5 and the second thread pair 6 are used to provide power and tensile force, realizing a ±2 mm adjustment range in the X and Y axis directions, with an adjustment accuracy of 0.25° / revolution; the third thread pair 7, the fourth thread pair 8, and the fifth thread pair 9 are used to provide power, enabling a ±4° angular adjustment range for pitching / deflection, with an adjustment accuracy of 0.23° / revolution, and Z-axis translation; the optical element mount 43 with a knurled knob is used to mount optical elements, which can rotate 360° with graduations, and the rotation graduation is 2°.

[0054] When adjusting the position of the optical element in the Y-axis direction by using the second thread pair 6, by screwing the second thread pair 6 inward, the floating ring 11 moves along the Y-axis direction under the push of the second thread pair 6 and the guiding action of the second guiding block 23, thereby driving the optical element to move along the Y-axis direction; and when the floating ring 11 moves along the Y-axis direction, the screw rod of the first thread pair 5 moves along the Y-axis direction in the corresponding second groove 33, so that the floating ring 11 does not displace in the X-axis direction, and the optical element only moves along the Y-axis direction, thereby enabling the position of the optical element in the Y-axis to be adjusted in a single direction; screwing out the second thread pair 6 outward can directly drive the floating ring 11 to move in the opposite direction of the Y-axis, realizing the reset of the floating ring 11;

[0055] When it is necessary to adjust the pitching / deflection angle of the optical element, directly screw the third thread pair 7, the fourth thread pair 8 and the fifth thread pair 9 inward to adjust the optical element to the required pitching / deflection angle.
