Fig. 1 is a schematic overall structure diagram of a four-dimensional adjustment device provided in an embodiment of the present application, and fig. 2 is a schematic explosion structure diagram of the four-dimensional adjustment device provided in the embodiment of the present application.

Referring to fig. 1 and 2, a four-dimensional adjustment apparatus provided in an embodiment of the present application includes: a translational adjustment mechanism 10 and a tilt adjustment mechanism 20 disposed on the translational adjustment mechanism 10.

Specifically, referring to fig. 1, the translational adjustment mechanism 10 may be located above the tilt adjustment mechanism 20. In some possible examples, the pan adjustment mechanism 10 may also be located below the tilt adjustment mechanism 20.

Alternatively, the pan adjustment mechanism 10 may be coupled to the centering lathe when the pan adjustment mechanism 10 is positioned above the tilt adjustment mechanism 20. The translational adjustment mechanism 10 may be connected to the lathe by a fixing bolt. When the pan adjustment mechanism 10 is located below the tilt adjustment mechanism 20, the tilt adjustment mechanism 20 may be coupled to a centering lathe.

In some possible designs, as shown in fig. 1 and 2, to facilitate the connection of the translational adjustment mechanism 10 to the centering lathe, a connecting member 40 may be further disposed above the translational adjustment mechanism 10, and the translational adjustment mechanism 10 is connected to the centering lathe through the connecting member 40.

Specifically, the connecting member 40 may be a flat plate having a through hole and/or a notch, wherein the through hole may be used for a bolt or a screw to pass through and connect with the centering lathe; the notch can also be used for a bolt or a screw to pass through and be connected with the centering lathe. It will be appreciated that only one of the through-holes or slots may be connected to the centering lathe by a bolt or screw. When the notch is connected with the centering lathe, the four-dimensional adjusting device can be translated greatly, the spherical center image of the large-caliber reflecting mirror can be positioned quickly, and the efficiency of positioning the spherical center image is improved.

Wherein, the inclination adjusting mechanism 20 includes: a first plate 21, a second plate 22 and at least three adjustment posts 23;

the second plate 22 is arranged right below the first plate 21, a first gap 24 is formed between the second plate and the first plate 21, and the first plate 21 and the second plate 22 are connected through an adjusting column 23. That is, the adjusting column 23 can not only adjust the gap between the first plate 21 and the second plate 22 (i.e., the first gap 24, for example, the gap between the first plate 21 and the second plate 22 shown in the z-axis direction in fig. 1 and 2), but also serve as a connecting member of the first plate 21 and the second plate 22.

At least three adjusting columns 23 respectively penetrate through the upper and lower surfaces of the first plate 21 and the second plate 22, and when any one of the adjusting columns 23 rotates with the first plate 21 and the second plate 22, the first gap 24 is used for adjusting to change the inclination angle of the optical centering instrument.

In some possible ways, the adjusting column 23 may be a screw or a bolt with external threads, and one of the first plate 21 and the second plate 22 has an internal threaded through hole matched with the external threads; thus the adjustment post 23 can be threaded to adjust the first gap 24 between the first plate 21 and the second plate 22.

In other possible ways, the adjusting column 23 may be a column structure, and a protrusion protruding in a radial direction is provided on the column structure, then a through hole having a sliding groove and a limiting step is provided on one of the first plate 21 or the second plate 22, and when the first gap 24 needs to be adjusted, the protrusion may be twisted to the sliding groove to slide and then be inserted into the limiting step, so that the first gap 24 can be adjusted in one step.

Alternatively, in some other possible ways, the adjusting column 23 is a screw or a bolt with external threads, and the first plate 21 and the second plate 22 are both provided with through holes with internal threads, wherein the through holes of the first plate 21 are provided with internal threads which rotate in the opposite direction to the internal threads of the through holes of the second plate 22; thus, when the adjusting column 23 is screwed, the first flat plate 21 and the second flat plate 22 can move simultaneously, and the adjusting efficiency is improved.

The four-dimensional adjusting device provided by the embodiment of the application is characterized in that the first flat plate 21 and the second flat plate 22 are connected through at least three adjusting columns 203 to form the whole inclination adjusting mechanism 20, and a first gap 24 is reserved between the first flat plate 21 and the second flat plate 22; thus, any one of the at least three adjusting columns 23 can adjust the distance of the first gap 24 between the first plate 21 and the second plate 22, and when one of the adjusting columns 21 is adjusted, the optical centering instrument can be inclined to one direction; through the mutual matching adjustment of at least three adjusting columns 23, the optical centering instrument can be inclined towards all directions of 360 degrees; therefore, the inclination angle of the optical centering instrument is increased and enriched, the actual requirement for optical centering of the large-caliber reflector is met, and the optical centering precision of the large-caliber reflector is ensured.

Optionally, at least three adjustment columns 23 are arranged in a regular polygon between the first plate 21 and the second plate 22.

Specifically, in the embodiment of the present application, the number of the adjusting columns 23 may be three, four, or five.

The adjusting columns 23 are arranged in a regular polygon mode, so that a wider inclination angle range can be covered when the adjusting columns 23 are matched for adjustment, and actual use requirements are guaranteed.

When the spherical center image of the large-caliber reflector is searched, the whole optical centering instrument is arranged on the four-dimensional adjusting device and then arranged on the centering lathe together. Therefore, when adjusting the inclination angle of the optical centering instrument, the adjusting column 23 needs to be twisted, so that the adjusting column 23 is prevented from falling off from the first plate 21 and falling onto the mirror surface of the reflector, which damages the mirror surface and causes great economic loss.

To this end, with continued reference to fig. 1 and 2, in the embodiment of the present application, the tilt adjustment mechanism 20 further includes: the anti-drop assembly 25 is arranged at the top end of the adjusting column 23, the first flat plate 21 and the second flat plate 22 are provided with through holes (not shown in the figure) for the adjusting column 23 to pass through, and the diameter of the anti-drop assembly 25 is larger than that of the through holes. Thus, when the adjusting columns 23 are screwed to a certain position (for example, taking fig. 1 as an example, when the optical centering apparatus needs to be inclined in the direction indicated by the arrow in the figure, the two adjusting columns 23 on the right side can be respectively screwed, namely, the first gap 24 between the first flat plate 21 and the second flat plate 22 on the right side is reduced, and the two adjusting columns 23 on the left side are unscrewed, namely, the first gap 24 between the first flat plate 21 and the second flat plate 22 on the left side is increased), when the two adjusting columns 23 on the left side are screwed to a certain position, the anti-falling component 25 is abutted against the upper surface of the first flat plate 21, and at this time, the two adjusting columns 23 on the left side cannot be screwed continuously, so that the falling of the adjusting columns 23 can be prevented, the safety of the use of the four-dimensional adjusting apparatus is effectively ensured, the reflecting mirror surface is protected.

Alternatively, the anti-slip assembly 25 may be a nut threadedly connected with the adjusting column 23; of course, in some possible ways, the anti-slip-off assembly 25 may also be a protrusion, a bump, a catch, a blocking wall, or the like protruding from the top end of the adjusting column 23 along the radial direction of the adjusting column 23, and in the embodiment of the present application, the specific structure of the anti-slip-off assembly 25 is not limited.

Further, with continued reference to fig. 1 and 2, the tilt adjustment mechanism 20 further includes: and the elastic component 26 is sleeved on the periphery of the adjusting column 23 and is positioned between the first flat plate 21 and the second flat plate 22, and two ends of the elastic component 26 are respectively abutted against the first flat plate 21 and the second flat plate 22.

Alternatively, in the embodiment of the present application, the elastic member 26 may be one of a compression spring, an elastic sponge block, or an elastic silicone block.

The two ends of the elastic component 26 are abutted to the first flat plate 21 and the second flat plate 22, so that when the first gap 24 is adjusted by the adjusting column 23, because the elastic component can provide linear elastic force change, the change of the first gap 24 is also linear, the situation that the spherical center image of the large-caliber reflector is difficult to find due to the sudden change of the angle when the optical centering instrument is subjected to inclination angle adjustment is avoided, the stability of the inclination angle adjustment of the optical centering instrument is ensured, and the determination efficiency of the spherical center image of the reflector is improved.

Optionally, fig. 3 is a schematic diagram of an overall structure of a four-dimensional adjustment apparatus according to another embodiment of the present application. Referring to fig. 3, in order to ensure the structural beauty of the whole four-dimensional adjusting device, a connecting portion 27 may be further provided below the first plate 21, and the connecting portion 27 may be fixedly connected to the lower surface of the first plate 21. The connecting portion 27 has a through hole with an internal thread. Thus, the adjusting column 23 is connected with the connecting part 27 through the second plate 22, a containing groove can be arranged on the first plate 21, and the top of the adjusting column 23 penetrates into the containing groove. This allows the escape prevention member 25 to be received in the receiving recess without being projected on the upper surface of the first plate 21. The beauty of the upper surface of the first flat plate 21 is ensured.

Further, referring to fig. 1 to fig. 3, an adjusting apparatus provided in an embodiment of the present application further includes: the changeover mechanism 30.

Specifically, when the translational adjustment mechanism 10 is located below the tilt adjustment mechanism 20, the adapter mechanism 30 is disposed on a side of the translational adjustment mechanism 10 facing away from the tilt adjustment mechanism 20, and is connected to the translational adjustment mechanism 10.

When the tilt adjustment mechanism 20 is located below the pan adjustment mechanism 10, the adapter mechanism 30 is disposed on a side of the tilt adjustment mechanism 20 facing away from the pan adjustment mechanism 10 and is connected to the tilt adjustment mechanism 20.

The changeover mechanism 30 includes: a first connecting member 31 provided on the translational adjustment mechanism 10 or on the tilt adjustment mechanism 20,

and the second connecting piece 32 is detachably arranged on one side of the first connecting piece 31, and the second connecting piece 32 is used for being connected with the optical centering instrument.

In a specific use, the four-dimensional adjusting device provided in the embodiment of the present application may be first installed on the centering lathe, and then the optical centering instrument is installed on the second connecting member 32. Thus, since the second connector 32 is detachably connected to the first connector 31; therefore, the second connecting member 32 can be easily connected to the first connecting member 31 together with the optical centering apparatus, or the optical centering apparatus can be easily detached from the four-dimensional adjusting apparatus. The installation convenience of the optical centering instrument is improved.

In some alternative embodiments, referring to fig. 2-4, fig. 4 is an exploded view of a tilt adjustment mechanism and a transfer mechanism of a four-dimensional adjustment device provided in an example of the present application. In the embodiment of the present application, the first connecting member 31 and the second connecting member 32 are both annular structures, the inner sidewall of the first connecting member 31 abuts against the outer sidewall of the second connecting member 32, and the optical centering instrument is installed in the second connecting member 32.

In this way, the first connecting piece 31 and the second connecting piece 32 are both arranged in an annular structure, and the outer side wall of the second connecting piece 32 is abutted against the inner side wall of the first connecting piece 31; when the second connecting piece 32 is installed on the first connecting piece 31, the second connecting piece 32 and the axis of the first connecting piece 31 are in the same position, that is, the second connecting piece 32 and the first connecting piece 31 are coaxially arranged, so that the stability of the connection between the second connecting piece 32 and the first connecting piece 31 is ensured. Meanwhile, the optical centering apparatus is installed in the second connector 32, so that the second connector 32 can play a certain role of protection for the optical centering apparatus.

Alternatively, the second connector 32 may be an annular flange to which the optical centraliser may be attached at the time by means of screws, bolts, screws, etc. It is understood that the second connector 32 may also be a ring structure having a snap structure, and the optical centering apparatus may be snapped with the second connector 32 through the snap structure.

Of course, in some possible ways, the second connector 32 may be connected to the optical centering apparatus by a screw thread, for example, an inner screw thread is provided on an inner side wall of the second connector 32, and an outer screw thread is provided at a connection position (for example, an outer side wall of the optical centering apparatus) of the optical centering apparatus and the second connector 32, so as to connect the second connector 32 to the optical centering apparatus.

It should be further noted that the first connecting member 31 and the second connecting member 32 can be connected by a connecting tool such as a bolt, a screw rod, or a thread. Of course, since the optical centering device has a certain weight (about 2-4 kg), after the optical centering device is installed on the second connecting member 32, the first connecting member 31 and the second connecting member 32 are connected by bolts, screws or threads, which may cause inconvenience in installation and connection, and even cause a problem that the optical centering device drops. Thus, referring to fig. 4 and 5, fig. 5 is a partial enlarged view at a in fig. 4. In the embodiment of the present application, the inner sidewall of the first connecting member 31 has at least two clamping grooves 311, the outer sidewall of the second connecting member 32 has at least two clamping arms 321, and the at least two clamping arms 321 are embedded in the at least two clamping grooves 311 to connect the first connecting member 31 and the second connecting member 32.

The cross section of the engaging groove 311 is "L" shaped, and the engaging groove 311 penetrates the edge of the first connecting member 31.

Thus, when the first connecting member 31 and the second connecting member 32 are assembled and connected, taking fig. 5 as an example, the first connecting member 31 and the second connecting member 32 can be conveniently connected by merely inserting the snap-in arm 321 into the vertical section of the "L" shaped snap-in groove 311 and then screwing the second connecting member 32 counterclockwise (which is only an illustrative example, and in some possible ways, may be screwing clockwise, and in the embodiment of the present application, the screwing direction of the second connecting member 32 is not limited). The connection of the first connector 31 with the second connector 32 is facilitated.

It is understood that the number of the latch grooves 311 and the latch arms 321 may be three, four, or five, etc. The catching grooves 311 and the catching arms 321 may be uniformly arranged along the circumferential direction of the first connector 31 or the second connector 32.

The moving member 112 is provided with two rectangular sliding rails 1121 matched with the rectangular sliding grooves 1111; the rectangular sliding rail 1121 is embedded in the rectangular sliding slot 1111 and can slide in the rectangular sliding slot 1111, and when the rectangular sliding rail 1121 slides in the rectangular sliding slot 1111, the moving member 112 is driven to move relative to the fixing member 111.

Thus, through the matching of the two rectangular sliding grooves 111 and the two rectangular sliding rails 1121, the rigidity and the bearing capacity of the sliding rail are increased, and the stability and the safety of the optical centering instrument during translation are ensured.

Specifically, in the embodiment of the present application, the fixing member 111 may be relatively fixed, for example, when the first translating assembly 11 is connected to the centering lathe, the fixing member 111 of the first translating assembly 11 may be fixed relative to the centering lathe. While the moving member 112 moves relative to the centering lathe.

It will be appreciated that, since the second translating assembly 12 is arranged on the first translating assembly 11, the fixed part 111 of the second translating assembly 12 is also moved with respect to the centering lathe when the moving part 112 of the first translating assembly 11 is moved. While being adjusted by the second moving assembly 12, the fixed part 111 of the second moving assembly 12 is fixed with respect to the centering lathe, and the moving part 112 of the second moving assembly 12 is moved with respect to the centering lathe.
