Fig. 1 is a schematic structural diagram of an integrating rod clamping device according to an embodiment of the present disclosure. For ease of understanding, integrator rod 100 and light source adapter 70 are shown in fig. 1, it being explained that integrator rod 100 and light source adapter 70 are not part of the structure of an integrator rod holder.

As shown in fig. 1, the integrating rod holding device includes at least: the method comprises the following steps of (1) installing a reference plate 10, a fixed seat group and an installation cylinder (comprising a first installation cylinder 31 and a second installation cylinder 32 in the figure); the installation reference plate 10 is used for providing an installation reference, and is a part forming an illumination light path; the fixing seat group at least comprises two fixing seats (consisting of an upper fixing seat 22 and a lower fixing seat 21 in the figure) which are oppositely arranged, and the bottoms of the fixing seats are fixed on the upper plate surface of the installation datum plate 10; the opening has at the installation section of thick bamboo both ends, and inside is provided with installation cavity 33, and integrating rod 100 sets up in installation cavity 33, sets up a plurality of clamping parts 41 in the installation cavity 33, through a plurality of (for example in figure 1) clamping part 41 with integrating rod 100 be fixed in the installation section of thick bamboo, installation section of thick bamboo and fixing base fixed connection, through the fixing base with installation section of thick bamboo fixed mounting on the installation benchmark board promptly, and then realize integrating rod's rigidity.

Fig. 2 is a schematic structural view of the clamping portion 41. As shown in fig. 2, the clamping portion 41 is a split structure, and includes an upper pressing member 412 and a lower pressing member 411; the clamping portion 41 is designed such that after the integrating rod 100 is pressed by the upper pressing member 412 and the lower pressing member 411, a gap is formed between a lower wall surface 4121 of the upper pressing member and an upper wall surface 4111 of the lower pressing member, threaded holes are formed in the mounting cylinder corresponding to the cylinder walls of the upper pressing member 412 and the lower pressing member 411, and the outer wall surface of the integrating rod 100 is clamped by the upper pressing member 412 and the lower pressing member 411 through locking of screws 51 (see fig. 1).

So, through setting up the clamping part into the components of a whole that can function independently structure, make things convenient for the centre gripping installation of integrating rod, the last piece that compresses tightly of clamping part has gapped design behind the piece of compressing tightly with lower compressing tightly piece pressfitting part, guarantees that the internal face that compresses tightly has sufficient area of contact with the contact surface of integrating rod, increase frictional force, reduces the stress of contact.

With continued reference to fig. 2, the outer wall 4120 of the upper pressing member 412 and the outer wall 4110 of the lower pressing member 411 are provided with a groove 410 at a position corresponding to the threaded hole, and after the screw is tightened through the threaded hole, the end of the screw abuts against the groove wall of the groove 410.

The setting of recess on the clamping part plays the guide orientation to the end of screw on the one hand, and on the other hand prevents to compress tightly an axial float and rotation in a circumferential direction, and then prevents the axial float and the rotation in a circumferential direction of total mark stick, realizes effectively fixing the total mark stick.

It is easily understood that the outer wall surface of the upper pressing member and the outer wall surface of the lower pressing member mean wall surfaces exposed to the outside after the upper pressing member and the lower pressing member are pressed, for example, wall surfaces indicated by 4120 and 4110 in fig. 2.

In one example, the screw may be a flat-end screw, that is, the end of the screw is a screw with a planar structure, and the grooves on the upper pressing member and the lower pressing member are circular grooves adapted to the end of the flat-end screw. On one hand, the flat-end screw is adopted as the screw, so that the problem that the optical performance of the integral rod is influenced because the screw end penetrates through the outer wall of the clamping part to damage the integral rod due to screwing transition is avoided; on the other hand, the screw end cooperates with circular recess and realizes that the screw is connected more firmly with the line contact of the outer wall of last pressing member in the circumferencial direction, plays the spacing effect to last pressing member simultaneously, prevents that the installation section of thick bamboo from scurrying and circumferential direction in the axial.

In order to further ensure the clamping force of the clamping portion 41 on the integrator rod, a plurality of threaded holes, for example, two threaded holes, may be provided at intervals on the mounting cylinder corresponding to the cylinder walls of the upper pressing member 412 and the lower pressing member 411, and two grooves 410 may be provided on the outer wall surfaces of the upper pressing member 412 and the lower pressing member 411 corresponding to the two threaded holes (see fig. 3).

In an example, the integrating rod 100 is a rectangular parallelepiped structure, the lower wall surface 4121 of the upper pressing member 412 is a planar structure, the upper wall surface 4111 of the lower pressing member 411 is provided with a containing groove 4112, and an avoiding notch 41120 is formed in the inner wall surface of the containing groove 4112 corresponding to the corner position of the integrating rod 100, so that the damage caused by the collision between the corner of the integrating rod and the inner wall of the containing groove in the installation process can be prevented.

It will be readily appreciated that the clamping portion may be located adjacent the end of the mounting cylinder in order to facilitate mounting of the integrating rod into the mounting cylinder.

Returning to fig. 1, a plurality of (for example, two in fig. 1) guide sleeves 42 arranged at intervals are further arranged in the mounting cavity 33 of the mounting cylinder, the outer wall surface of each guide sleeve 42 is tightly attached to the inner wall surface of the mounting cavity 33, and the inner wall surface is tightly attached to the outer wall surface of the integrating rod 100; the inner wall surface of the guide sleeve 42 is provided with an avoidance gap corresponding to the corner position of the integrating rod 100.

Exemplarily, the built-in through-hole with the sectional shape looks adaptation of integrating rod of uide bushing, for example, the integrating rod is the cuboid structure, then sets up the rectangle through-hole in the uide bushing, sets up on four angles of rectangle through-hole and dodges the breach to dodge four edges and corners of integrating rod, the integrating rod break-through is worn to locate in the uide bushing through the rectangle through-hole.

It is easy to understand, the quantity of uide bushing is set up to visual integrator rod's length, if the length of integrator rod is longer (for example >100mm), then the uide bushing quantity is a plurality ofly (for example 2), and the interval sets up, and one of them sets up in the one end that the clamping part was kept away from to the installation cavity, for further fixed integrator rod, sets up the screw hole in the position that the installation section of thick bamboo corresponds the uide bushing, and through the outer wall of fastener fastening locking messenger's uide bushing and integrator rod closely laminating, further fixed integrator rod. If the length of the integrating rod is short (for example 50mm), only one guide sleeve can be arranged at one end far away from the clamping part, and the integrating rod is supported and limited under the combined action of the guide sleeve and the clamping part.

The arrangement of the guide sleeve in the integrating rod clamping device in the embodiment plays roles in supporting and limiting the integrating rod, and ensures that the central axis of the integrating rod is coaxial with the optical axis of the light beam; simultaneously, the corresponding edges and corners position of the internal face of the guide sleeve is provided with an avoiding notch, so that the damage of the edges and corners of the integrating rod in the assembling process is further effectively prevented.

In one example, the adapter 61 and the light source interface 62 are respectively disposed at two ends of the mounting cylinder, and the mounting cylinder is fixedly connected with at least two oppositely disposed fixing seats through the adapter 61 and the light source interface 62.

With continued reference to fig. 1, the integrating rod holding apparatus further comprises: an adjustment ring 80; the adjusting ring 80 is arranged between the end part of the mounting cylinder close to the light source interface part 62 and the light source interface part 62, after the light source interface part 62 and the mounting cylinder are mounted in place, two opposite end faces of the adjusting ring 80 are respectively abutted against the end face of the mounting cylinder and the end face of the light source interface part 62, and after the light source joint 70 and the light source interface part 62 are mounted in place, a gap is formed between a light emitting face of the light source joint 70 and the integrating rod 100.

It is easy to understand that the adaptor and the mounting cylinder, the light source interface and the mounting cylinder, and the light source interface and the light source connector can be fixedly connected by adopting a proper connection mode according to the actual situation, including but not limited to connection modes such as plugging, screwing and the like; the adaptor and the installation section of thick bamboo, light source interface spare and light source connect simultaneously, and the three can adopt the same connected mode, also can adopt different connected modes, and this application does not prescribe a limit.

For example, the adapter and the mounting cylinder are connected by screw connection, and the light source interface and the mounting cylinder, and the light source interface and the light source connector are connected by plug connection; or the adaptor and the mounting cylinder, the light source interface and the mounting cylinder, and the light source interface and the light source connector all adopt a connection mode of splicing or screwing.

When the adaptor and the mounting cylinder or the light source interface and the light source connector are connected and fixed in a screwed connection mode, the adaptor and the mounting cylinder or the light source interface and the light source connector are provided with guide matching surfaces, on one hand, the assembling efficiency of the adaptor and the mounting cylinder or the light source interface and the light source connector is increased, on the other hand, the axial positioning of the adaptor and the mounting cylinder or the light source interface and the light source connector is ensured.

In order to further ensure the installation stability of the light source adaptor 62 and the installation cylinder, after the light source adaptor and the installation cylinder are installed in place, the light source adaptor and the installation cylinder are fastened and connected through a fastening piece, for example, in fig. 1, the fastening piece is a thin nut 53 with a large diameter, an external thread is arranged at the connecting end of the light source adaptor and the installation cylinder, and the light source adaptor and the installation cylinder are fastened through screwing of the thin nut 53 and the external thread, so that the connection of the light source adaptor and the installation cylinder is more reliable.

In one example, the outer wall profiles of the adapter piece 61 and the light source interface piece 62 are both circular; as shown in fig. 4, the inner wall surface 23 of the fixing seat is an arc surface adapted to the outer wall surfaces of the adaptor 61 and the light source adaptor 62; the fixing base is the components of a whole that can function independently structure, including last fixing base 22 and lower fixing base 21, it sets up engaging lug 24 on fixing base 22 and the lower fixing base 21 respectively to go up, set up connecting hole 240 on the engaging lug 24, go up behind the outer wall of fixing base 22 and lower fixing base 21 pressfitting adaptor 61 or light source interface piece 62, the engaging lug 24 of going up fixing base 22 and the engaging lug of lower fixing base 21 have the clearance, pass connecting hole 240 fastening connection on the engaging lug 24 through the fastener and go up fixing base 22 and lower fixing base 21, and then with adaptor and the fixed centre gripping of light source interface piece and fixing base, and then guarantee the rigidity of an installation section of thick bamboo, and then guarantee the rigidity of the integrating rod of installing in the installation section of thick bamboo.

The utility model provides an integral rod clamping device sets up the internal face of fixing base into the arc surface with the outer wall adaptation of adaptor and light source interface spare, conveniently adjusts the angle of integral rod.

With continued reference to fig. 4, the bottom of the lower fixing base 21 is provided with a connecting plate 210 extending to one side, and the connecting plate 210 is provided with a plurality of kidney-shaped holes 2100, for example, in fig. 4, two kidney-shaped holes 2100 are respectively provided at two opposite ends of the connecting plate 210; the fastener fixedly connects the lower fixing base 21 to the mounting reference plate 10 through the kidney hole 2100. The arrangement of the waist-shaped hole is beneficial to the adjustment of processing or installation errors.

In another example, a water cooling jacket 90 is sleeved on the outer wall of the mounting cylinder, a liquid outlet a is arranged on the upper wall surface of one end of the water cooling jacket 90 at two opposite ends, and a liquid inlet B is arranged on the lower wall surface of the other end (see fig. 1), when a high-power light beam passes through the integrating rod, the liquid inlet B can be filled with cooling liquid, the cooling liquid cools the outer wall of the mounting cylinder, so that the integrating rod is cooled, and the cooling liquid with the increased temperature flows out of the liquid outlet.

For example, the laser light source is used as the light source input, so that the laser light source can bear large input power, the long side of the section of the light bar is more than or equal to 3mm, the short side of the section of the light bar is more than or equal to 2mm, and the length of the section of the light bar is more than or equal to 100 mm.

It is easy to understand that, in order to realize cooling of the integrator rod, the water cooling jacket should cover a large area of the outer wall of the mounting cylinder as much as possible, for example, in fig. 1, one end of the opposite ends of the water cooling jacket 90 abuts against the adaptor 61, and the other end extends to the vicinity of the light source adaptor 62, so that the water cooling jacket covers a large area of the outer wall surface of the mounting cylinder, and effective cooling of the integrator rod is realized.

In order to limit the displacement of the water cooling jacket in the axial direction and the circumferential direction, a large-diameter thin nut 53 is arranged at one end of the water cooling jacket 90 close to the light source interface part 62 for fastening and locking, illustratively, an external thread is arranged on the outer wall surface of the end part of the mounting cylinder close to the water cooling jacket (the end close to the light source interface part), and the thin nut 53 is matched with the external thread to lock the water cooling jacket 90 (see fig. 1).

In order to make the cooling liquid fully contact with and smoothly circulate through the outer wall surface of the mounting cylinder, the outer wall surface of the mounting cylinder is provided with spline grooves 303 extending along the length direction thereof and a plurality of cooling ring grooves 302 extending along the circumferential direction thereof (see fig. 5).

In order to ensure that the cooling liquid only flows between the water cooling jacket and the outer wall of the installation cylinder and prevent the cooling liquid from flowing out, the two opposite ends of the water cooling jacket are in sealing connection with the outer wall surface of the installation cylinder, for example, a sealing ring 52 is arranged between the two opposite ends of the water cooling jacket and the outer wall surface of the installation cylinder to realize sealing connection, and the space between the water cooling jacket and the installation cylinder is sealed and isolated from the external space to prevent the cooling liquid from flowing out.

Returning to fig. 5, sealing ring grooves 301 for mounting sealing rings are provided on the outer wall of the mounting cylinder at positions corresponding to both ends of the cooling jacket, and the sealing rings 52 are provided in the sealing ring grooves, so that the positions of the sealing rings are fixed.

Of course, if the application scene of the integrating rod is a low-power light source, the water cooling jacket is not needed, and the spline groove, the water cooling ring groove, the sealing ring groove and the sealing ring are correspondingly not needed to be arranged on the outer wall of the mounting cylinder.

In another example, the mounting cylinder includes a first mounting cylinder 31 and a second mounting cylinder 32, the first mounting cylinder 31 is screwed with the second mounting cylinder 32, and one cooling ring groove 302 of the plurality of cooling ring grooves 302 is disposed at a connection position of the first mounting cylinder 31 and the second mounting cylinder 32.

For example, the ends of the first installation cylinder 31 and the second installation cylinder 32 are respectively provided with an L-shaped wall surface, after the first installation cylinder 31 and the second installation cylinder are installed in place, the two L-shaped wall surfaces are combined to form the cooling ring groove 302, the cooling ring groove is arranged here to prevent the first installation cylinder and the second installation cylinder from being locked in a screwing manner, the groove of the spline groove on the outer wall of the first installation cylinder is not aligned with the groove of the spline groove on the outer wall of the second installation cylinder, so that the cooling liquid is blocked, the cooling liquid can only circulate on the outer wall surface of the second installation cylinder, and the cooling liquid can not reach the outer wall surface of the first installation cylinder, so that the outer wall of the first installation cylinder can not be cooled.

In order to prevent the cooling liquid from flowing into the mounting cavity through the joint of the first mounting cylinder and the second mounting cylinder and damaging the integrator rod, the joint of the first mounting cylinder and the second mounting cylinder is subjected to sealing treatment, for example, a sealing ring is arranged between the first mounting cylinder and the second mounting cylinder, so that the first mounting cylinder and the second mounting cylinder are connected in a sealing manner.

The installation cylinder is of a split structure, so that the installation of a long and thin integrating rod is facilitated, and the integrating rod is not easy to damage.

Of course, if the length of the integrating rod is short, the mounting cylinder does not need to adopt a split structure, the first mounting cylinder and the second mounting cylinder can be combined into a part, and a sealing ring and a guide sleeve (namely the sealing ring and the guide sleeve arranged at the connecting position of the first mounting cylinder and the second mounting cylinder) are removed.

The use and assembly steps of the integrating rod clamping device provided by the embodiment of the application are as follows: except for the installation reference plate 10, the lower fixed seat 21, the upper fixed seat 22 and the light source connector 70 in fig. 1, the components are firstly assembled into a whole, then the whole is placed in the arc groove of the lower fixed seat 21, the two positions are total, the angle of the integrating rod can be adjusted along the circumferential direction to meet the requirement of a light path, and then the upper fixed seat 22 is installed and fastened by screws, so that the modular design is realized.
