Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of supporting rotating tables, in particular to an optical equipment stable supporting rotating table. BACKGROUND

[0002] The optical equipment stable supporting rotating table is a core component for providing stable and precise positioning in optical experiments, measurement or processing systems. For example, CCD / CMOS cameras, video monitors and photoelectric detectors in detection and imaging equipment, and collimated light sources in laser and light source equipment all use supporting rotating tables.

[0003] The current supporting rotating table mainly includes a fixed base at the bottom, a rotating platform for circumferential rotation, and a pitch platform for adjusting the pitch angle. The optical equipment is fixed on the pitch platform. During use, the circumferential angle is adjusted by the rotating platform, and the pitch angle is adjusted to the set pitch angle by the pitch platform.

[0004] In the existing stable supporting rotating table, the following problems exist: after adjusting the pitch angle, the current method is to use an internal mechanical locking method to lock at the axis of rotation of the pitch platform. The optical equipment is usually long and cylindrical. Therefore, when locked by the existing method, a cantilever beam structure appears. When the pitch angle is set, the supporting state is not stable due to the gravity of the optical equipment and the pitch platform, which affects the normal use of the optical equipment. In addition, the internal locking method requires internal components at the rotating part, which increases the design cost. Therefore, during the use of the optical equipment in detection and imaging equipment, the difficulty of maintaining the set pitch angle for a long time increases, and the stability is poor.

[0005] Therefore, there is an urgent need for an optical equipment stable supporting rotating table that can solve the supporting requirements of the optical equipment during locking and the requirements of long-term maintenance of the set pitch angle. SUMMARY

[0006] Therefore, it is necessary to provide an optical equipment stable supporting rotating table to solve the above problems of the prior art.

[0007] The present application provides an optical equipment stable supporting rotating table, which comprises a base, a U-shaped rotating table rotatably arranged on the base, the opening of the rotating table facing upward, and a U-shaped mounting table rotatably arranged between the two vertical segments of the rotating table through a rotating shaft.

[0010] The diagonal brace, together with the mounting platform and the vertical section of the rotating platform, forms a triangular frame.

[0012] The locking assembly also includes a movable plate. A movable plate sleeved on the rotating shaft is fixedly mounted on the movable column. A spring for resetting the movable plate is provided between the movable plate and the movable column. A matching groove is provided through the upper end of the movable plate on the left and right.

[0013] The mounting platform has multiple extrusion strips hinged to each other on both sides of its two vertical sections. All extrusion strips are evenly distributed circumferentially around the surface of the rotating shaft and are located in the mating groove. The outer circumferential surface of the extrusion strips is inclined from top to bottom toward the vertical section of the rotating platform, and the inner wall of the mating groove is mated with the outer circumferential surface of the extrusion strips.

[0014] According to an advantageous embodiment, the diagonal bracing plate is fixedly sleeved on the movable column, and the two diagonal bracing plates are respectively located on the left and right sides of the rotating platform. Two docking cylinders with left and right axes are fixedly installed on the opposite sides of the two vertical sections of the mounting platform, and docking rods are provided on the diagonal bracing plates.

[0015] By connecting the connecting rod to the connecting cylinder, the diagonal brace, the mounting platform, and the vertical section of the rotating platform together form a triangular frame.

[0016] According to an advantageous embodiment, the opening of the docking cylinder and the end of the docking rod near the docking cylinder are both chamfered. When the center of gravity of the optical device is located on the front side of the rotation axis, the docking rod docks with the front docking cylinder, and when the center of gravity of the optical device is located on the rear side of the rotation axis, the docking rod docks with the rear docking cylinder.

[0017] According to an advantageous embodiment, a rectangular groove is provided on the inclined support plate, and a sliding seat is slidably disposed in the rectangular groove along the length direction of the inclined support plate.

[0018] The second locking assembly includes a sliding block, a receiving cavity is provided in the sliding seat, the sliding block is slidably arranged in the receiving cavity, a spring is provided between the sliding block and the receiving cavity, and a connecting rod is fixedly arranged at the end of the sliding block facing the mounting platform.

[0019] The upper and lower end faces of the sliding seat are both slidably equipped with abutment plates via a sliding rod. Two springs distributed front and back are provided between the abutment plates and the sliding seat. The end face of the sliding rod near the sliding block is a hemispherical surface.

[0020] The upper and lower end faces of the sliding block are provided with mating grooves. The two mating grooves are symmetrical to each other. The upper mating groove is divided into an upper horizontal section, an inclined section and a lower horizontal section in the direction from the mounting platform to the brace plate. The distance between two adjacent lower horizontal sections is smaller than the distance between two adjacent upper horizontal sections. The inclined section connects the upper horizontal section and the lower horizontal section.

[0021] According to an advantageous embodiment, the upper and lower inner walls of the rectangular groove are provided with mounting grooves, and a mating plate is movably installed in the mounting groove.

[0022] According to an advantageous embodiment, the opposing surfaces of the mating plate and the corresponding abutting plate are both made of cast iron.

[0023] According to an advantageous embodiment, the mating plate and the corresponding abutting plate each have a plurality of triangular grooves continuously distributed along the length of the bracing plate on their opposite surfaces.

[0024] According to an advantageous embodiment, the locking unit further includes a locking hole, and the moving plate has a locking hole extending through it from front to back. The two vertical sections of the rotating platform are each provided with a locking rod that slides back and forth on their opposite surfaces and engages with the corresponding locking hole.

[0025] In summary, the present invention has at least one of the following beneficial effects: First, the present invention forms a two-point locking through the locking process of locking group one and locking group two, and after final locking, a rigid triangular frame is formed by the vertical sections of the inclined brace plate, mounting platform and rotating platform, which avoids the problem of the overall stability being affected by the cantilever beam structure and improves the stable support effect for optical equipment. Secondly, by using external support and locking, stable support is provided while avoiding the high cost design of built-in components.

[0026] Second, in this invention, the locking method of the contact plate and the mating plate is selected according to the frequency of pitch angle changes, so as to be applicable to two situations: frequent adjustment of the pitch angle and long-term maintenance of a certain pitch angle.

[0037] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0038] like Figure 1 As shown, an optical device stable support turntable includes: a base 1, on which a U-shaped turntable 2 is rotatably mounted, the opening of the turntable 2 facing upward, and a U-shaped mounting platform 3 is rotatably mounted between the two vertical sections of the turntable 2 via a common rotation axis, and the optical device (not shown in the figure) is mounted in the U-shaped area of ​​the mounting platform 3.

[0039] The rotary table 2 is provided with a locking unit 4 for locking the mounting platform 3. The locking unit 4 includes a bracing plate 40. The two vertical sections of the rotary table 2 are slidably provided with bracing plates 40 on their opposite sides, and the mounting platform 3 and optical equipment are supported by the bracing plates 40.

[0040] like Figure 1 , Figure 2 , Figure 3 and Figure 7 As shown, the locking unit 4 also includes a locking group 1 42 for initially locking the mounting platform 3 and a locking group 2 43 for rigidly locking the inclined support plate 40. The locking group 1 42 is located between the vertical section of the mounting platform 3 and the vertical section of the rotating platform 2, and the locking group 2 43 is located on the inclined support plate 40. The locking group 1 42 includes an extrusion strip 420 for pressing and locking the rotating shaft, and the locking group 2 43 includes a docking cylinder 430 and a docking rod 431 for locking the mounting platform 3 and the inclined support plate 40.

[0041] The diagonal brace 40, together with the mounting platform 3 and the vertical section of the rotating platform 2, forms a triangular frame. During the locking process of the diagonal brace 40, the locking group 1 42 first forms an elastic initial lock at the rotating shaft, then the locking group 2 43 elastically locks the diagonal brace 40, and finally the rigid lock of the locking unit 4 makes the triangular frame form a rigid support frame.

[0042] It should be noted that both the rotary table 2 and the mounting table 3 are driven by external rotary motors. For example, the mounting table 3 adjusts its pitch angle relative to the optical equipment under the drive of the external rotary motor, while the rotary table 2 adjusts the circumferential angle of the optical equipment during rotation.

[0043] During operation, after the optical equipment is installed on the mounting platform 3, when the mounting platform 3 rotates to the set pitch angle, the locking unit 4 operates to make the inclined support plate 40 slide towards the mounting platform 3. The rotating shaft is elastically locked by the extrusion strip 420 in the locking group 1 42, and the docking rod 431 in the locking group 2 43 docks with the docking cylinder 430 to form two preliminary triangular frames on the left and right. Finally, the locking unit 4 locks the position of the inclined support plate 40, so that the triangular frame forms a rigid triangular frame, that is, the pitch angle of the mounting platform 3 is locked. In the above way, the mounting platform 3 and the optical equipment are provided with stable support at the required set pitch angle. It should be noted that when the pitch angle needs to be adjusted later, the locking unit 4 should be activated first, and then the pitch angle should be adjusted. Finally, the above locking process is repeated to reset to a stable support state.

[0044] like Figure 1 and Figure 3 As shown, the locking unit 4 also includes a movable column 41. The movable column 41, which slides horizontally through both vertical sections of the rotating platform 2, is driven to move left and right by an external hydraulic cylinder.

[0045] like Figure 1 , Figure 3 and Figure 4 As shown, the locking assembly 42 also includes a movable plate 410. The movable plate 410, which is sleeved on the rotating shaft, is fixedly mounted on the movable column 41. A spring 411 for resetting the movable plate 410 is provided between the movable plate 410 and the movable column 41. A fitting groove 412 is provided through the upper end of the movable plate 410 on the left and right.

[0046] Multiple extrusion strips 420 are hinged to each other on the two vertical sections of the mounting platform 3. All extrusion strips 420 are evenly distributed circumferentially around the surface of the rotation axis and are all located in the mating groove 412. The outer circumferential surface of the extrusion strip 420 is inclined from top to bottom toward the vertical section of the rotating platform 2. The inner wall of the mating groove 412 is mated with the outer circumferential surface of the extrusion strip 420.

[0047] After the mounting platform 3 is adjusted to the set pitch angle, the external hydraulic cylinder operates, causing the moving column 41 to drive the moving plate 410 to move synchronously towards the mounting platform 3. This causes the spring 411 to deform, and the inner wall of the mating groove 412 on the moving plate 410 gradually squeezes all the extrusion strips 420. All the extrusion strips 420 gradually adhere to the outer side of the rotating shaft. It should be noted that the opposing surfaces of the extrusion strips 420 and the rotating shaft, as well as the outer circumferential surface of the rotating shaft, are made of materials with a high coefficient of friction. Therefore, during the above extrusion process, the friction between the extrusion strips 420 and the rotating shaft increases, thereby initially locking the mounting platform 3 through the above process. The elastic force generated by the deformation of the spring 411 facilitates the subsequent reset process by pushing the moving plate 410 to reset.

[0048] like Figure 1 , Figure 2 and Figure 7 As shown, the inclined support plate 40 is fixedly sleeved on the movable column 41. The two inclined support plates 40 are located on the left and right sides of the rotating table 2 respectively. Two docking cylinders 430 with left and right axes are fixedly installed on the opposite sides of the two vertical sections of the mounting platform 3. The inclined support plate 40 is provided with docking rods 431.

[0049] The connection between the connecting rod 431 and the connecting cylinder 430 enables the diagonal brace 40, the mounting platform 3, and the vertical section of the rotating platform 2 to form a triangular frame.

[0050] The opening of the docking cylinder 430 and the end of the docking rod 431 near the docking cylinder 430 are both chamfered. When the center of gravity of the optical equipment is located on the front side of the rotation axis, the docking rod 431 docks with the front docking cylinder 430. When the center of gravity of the optical equipment is located on the rear side of the rotation axis, the docking rod 431 docks with the rear docking cylinder 430.

[0051] Before installing the optical equipment onto the mounting platform 3, the external hydraulic cylinder operates, moving the column 41 to move the inclined support plate 40 away from the mounting platform 3. The docking rod 431 disengages from the docking cylinder 430. At this point, the inclined support plate 40 is adjusted according to the center of gravity position of the optical equipment to be installed, so that the docking rod 431 is aligned with the docking cylinder 430 again. The external hydraulic cylinder then operates, causing the inclined support plate 40 to reset and move closer to the mounting platform 3. The docking rod 431 inserts into the corresponding docking cylinder 430, completing the initial installation of the mounting platform 3. The optical equipment is then installed onto the mounting platform 3. By selecting the docking and support positions based on the center of gravity position, support is directly provided at the offset position, improving support stability and avoiding the problem of high support strength and instability caused by supporting the end far from the center of gravity.

[0052] like Figure 1 and Figure 5 As shown, a rectangular groove 432 is provided on the inclined support plate 40, and a sliding seat 433 is slidably disposed in the rectangular groove 432 along the length direction of the inclined support plate 40.

[0053] like Figure 1 and Figure 7 As shown, the second locking assembly 43 includes a sliding block 434. A receiving cavity is provided inside the sliding seat 433. The sliding block 434 is slidably arranged in the receiving cavity. A second spring 435 is provided between the sliding block 434 and the inner wall of the receiving cavity. The connecting rod 431 is fixedly arranged at the end of the sliding block 434 facing the mounting platform 3.

[0054] like Figure 1 , Figure 5 , Figure 6 and Figure 7As shown, the upper and lower end faces of the sliding seat 433 are slidably provided with abutment plates 436 via sliding rods. Two springs 437 distributed front and back are provided between the abutment plates 436 and the sliding seat 433. The end face of the sliding rod near the sliding block 434 is a hemispherical surface.

[0055] The sliding block 434 has mating grooves 438 on both its upper and lower end faces. The two mating grooves 438 are symmetrical to each other. Taking the upper mating groove 438 as an example, the upper mating groove 438, from the mounting platform 3 to the inclined support plate 40, consists of an upper horizontal section, an inclined section, and a lower horizontal section. The distance between two adjacent lower horizontal sections is smaller than the distance between two adjacent upper horizontal sections. The inclined section connects the upper horizontal section and the lower horizontal section. It should be noted that both spring 2 435 and spring 3 437 can provide sufficient elastic force during the reset process. This characteristic process was obtained by those skilled in the art through multiple tests on the component materials and springs 2 435 and 3 437, and will not be elaborated further here.

[0056] like Figure 1 and Figure 6 As shown, the upper and lower inner walls of the rectangular groove 432 are provided with mounting grooves, and a mating plate 439 is movably installed in the mounting groove. It should be noted that the mating plate 439 is locked into the mounting groove by bolts, and the contact plate 436 can also be disassembled, so that the mating plate 439 and the contact plate 436 can be replaced after long-term use, thus maintaining the mating effect of the mating plate 439 and the contact plate 436.

[0057] After the docking rod 431 is inserted into the docking cylinder 430, the mounting platform 3 moves the optical equipment to the set pitch angle. Then, the external hydraulic cylinder operates, causing the moving column 41 and the inclined support plate 40 to move synchronously towards the mounting platform 3. During the movement, initial compression and locking occur at the rotation axis. Next, as the inclined support plate 40 gradually moves, the docking rod 431 contacts the bottom of the docking cylinder 430. At this point, the docking rod 431 stops moving with the inclined support plate 40, thereby causing relative movement between the inclined support plate 40 and the sliding block 434. The sliding rod starts moving from the lower horizontal section of the mating groove 438 and moves through the inclined section. When the sliding rod moves to the upper horizontal section, it is pushed up by the inner wall of the mating groove 438 when it passes the inclined section of the mating groove 438. Therefore, the sliding rod drives the abutment plate 436 on it to approach the mating plate 439. When the sliding rod moves to the upper horizontal section of the mating groove 438, the abutment plate 436 and the mating plate 439 are in close contact. During the above process, both spring 2 435 and spring 3 437 are deformed. Thus, during the subsequent unlocking and reset process, the elastic force generated by the deformation of spring 2 435 and spring 3 437 respectively causes the mating rod 431 and the abutment plate 436 to reset and move.

[0058] like Figure 8As shown, the opposing surfaces of the mating plate 439 and the corresponding contact plate 436 are both made of cast iron, which has a high coefficient of friction and good wear resistance.

[0059] After the contact plate 436 and the mating plate 439 are in close contact, the inclined support plate 40 is locked by the locking unit 4. At this time, the contact state between the contact plate 436 and the mating plate 439 is locked, and the friction generated between the two maintains the stable support for the mounting platform 3.

[0060] It should be added that when the optical equipment needs to be adjusted frequently and multiple times, a friction contact method is used for locking, which facilitates repeated locking and unlocking processes while providing stable support.

[0061] like Figure 6 As shown, the mating plate 439 and the corresponding contact plate 436 are provided with a plurality of triangular grooves that are continuously distributed along the length of the bracing plate 40 on their opposite surfaces.

[0062] During the contact process between the contact plate 436 and the mating plate 439, the triangular groove on the contact plate 436 and the triangular groove on the mating plate 439 engage with each other, and the inclined support plate 40 is locked by the locking unit 4, so that the contact state between the contact plate 436 and the mating plate 439 is locked, and the stable support for the mounting platform 3 is maintained by the engagement of the two.

[0063] It should be added that when adjusting the pitch angle of optical equipment and maintaining a certain pitch angle for a long time, using a locking mechanical cooperation method can provide a stronger stable support effect.

[0064] like Figure 1 and Figure 4 As shown, the locking unit 4 also includes a locking hole 45. The moving plate 410 has a locking hole 45 extending through it from front to back. The two vertical sections of the rotating table 2 are each provided with a locking rod 450 that slidably engages with the corresponding locking hole 45 on their opposite surfaces. The locking rod 450 is driven by an electric push rod to move back and forth.

[0065] After the initial locking of the mounting platform 3 is completed at the rotating shaft, the locking hole 45 moves with the moving plate 410 to be opposite the locking rod 450. The electric push rod works to move the locking rod 450 into the corresponding locking hole 45, locking the moving plate 410 and the moving column 41, and indirectly locking the left and right positions of the diagonal brace plate 40, so that the docking rod 431 is always located in the docking cylinder 430, and the contact plate 436 and the mating plate 439 maintain a close fit. At this point, the rigid locking of the triangular frame is completed, and a rigid triangular support frame is formed on the left and right sides of the mounting platform 3, improving the support stability of the mounting platform 3 and the optical equipment.

[0066] It should be further explained that, compared to the self-locking method at the rotating shaft in the prior art, this technical solution adds a bracing plate 40, a locking group 1 42, and a locking group 2 43. When locking is required, the locking group 1 42 performs initial locking at the rotating shaft, and the vertical sections of the bracing plate 40, the mounting platform 3, and the rotating platform 2 together form a triangular frame, which forms a rigid triangular support frame after final locking. Secondly, according to the frequency of the tilt angle adjustment of the optical equipment, the corresponding locking method is selected between the contact plate 436 and the mating plate 439 to adapt to different situations. The added components are all existing conventional components, but the support area is located outside the turntable, providing stable support while avoiding interference with the rotation process of the mounting platform 3 and the rotating platform 2 due to the built-in installation locking components. It can be used for a long time after a single installation. In summary, this technical solution is a specific improvement made entirely based on and to solve the defects of the prior art.
