[0040] As shown in Figures 1 to 3, the present invention provides a turbine seat ring guide vane positioning assembly device, comprising a turbine seat 1, a guide vane 2 and an assembly group 4, wherein the assembly group 4 comprises an assembly seat 403, the turbine seat 1 is placed on the assembly seat 403, that is, the assembly seat 403

[0041] The top surface is the bearing plane of the turbine base 1 .

[0042] Example 1

[0043] As shown in Figures 3 and 4, a cross plate 402 is installed in the assembly seat 403. The cross plate 402 consists of two mutually perpendicular and integrally formed plates. The end of the cross plate 402 extends to the outside of the assembly seat 403. A vertical rod 405 is installed on the cross plate 402. An external positioning block 401 is installed on the vertical rod 405. The outer end of the guide vane 2 contacts the external positioning block 401. The external positioning block 401 limits the position of the outer end surface of the guide vane 2. In order to simultaneously position multiple guide vanes 2 on the turbine base 1, the cross plate 402 can be composed of multiple plates. One end of the multiple plates converges together, and the other end forms a circle, and the angles between adjacent plates are the same.

[0044] A groove 404 is provided on the cross plate 402, the bottom of the vertical rod 405 is slidably connected to the groove 404, and the outer positioning block 401 is connected to the vertical rod 405.

[0045] The rod 405 is connected, and the vertical rod 405 moves along the groove 404 while driving the outer positioning block 401 to move.

[0046] The outer end surface of the guide vane 2 is limited. The movement of the multiple outer positioning blocks 401 changes the circular area surrounded by the multiple circumferentially arranged outer positioning blocks 401, thereby achieving the positioning of the guide vanes on turbine bases of multiple different diameters.

[0047] Furthermore, as shown in FIG4 , an outer positioning groove 304 is provided on the outer positioning block 401, and the outer end of the guide vane 2 is located at the outer

[0048] In the positioning groove 304, by inserting the outer end of the guide vane 2 into the outer positioning groove 304, the three-sided position of the guide vane 2 is limited, effectively limiting the position of the guide vane 2 and avoiding the position deviation of the guide vane 2 during assembly. In order to strengthen the contact surface between the guide vane 2 and the outer positioning groove 304,

[0049] Stability, as shown in Figure 9, a plurality of springs 418 are embedded in the outer positioning groove 304, the guide vane 2 is fixed, the outer positioning block 401 moves toward the guide vane 2, and the outer end of the guide vane 2 is inserted into the outer positioning groove 304. A rubber pad 417 is installed at the outer end of the spring 418. When the guide vane 2 contacts the rubber pad 417, the spring 418 is compressed. At the same time, due to the elastic force of the spring 418, the rubber pads 417 on three sides of the outer positioning groove 304 squeeze the guide vane 2, stably fixing the guide vane 2. The rubber pad 417 is in direct contact with the guide vane 2, which serves the purpose of anti-slip and protects the surface of the guide vane.

[0050] Furthermore, a rotating motor 419 is installed in the vertical rod 405, and the rotating motor 419 is connected to the external positioning block 401.

[0051] When assembling the guide vane 2, the guide vane 2 needs to be installed at a certain angle. When assembling multiple guide vanes separately, it is necessary to ensure that the guide vane 2 is installed correctly.

[0052] The angle is the same, the rotary motor 419 works, so that the outer positioning block 401 rotates relative to the vertical rod 405, and the outer positioning block 401 rotates relative to the vertical rod 405.

[0053] Drive the outer end of the guide vane 2 to rotate, improving the consistency of the guide vane installation angle during assembly.

[0054] As shown in FIG3 and FIG4, in addition to positioning the outer end surface of the guide vane 2 by the outer positioning block 401, the assembly seat 403

[0055] A support column 5 is installed on the support column 5, and an upper positioning group 3 is installed on the support column 5. The upper positioning group 3 and the support column 5 are slidably connected. The inner end surface of the guide vane 2 is positioned by the upper positioning group 3 to achieve the purpose of limiting the positioning of the inner and outer rings.

[0056] Specifically, the upper positioning group 3 includes a positioning seat 301, which is sleeved on the supporting column 5.

[0057] The inner positioning block 302 is arranged on the upper circumference. The position of the inner positioning block 302 corresponds to the position of the outer positioning block 401, completing the positioning of the inner and outer rings of the guide vane.

[0058] The inner positioning block 302 is mounted on the upper positioning seat 301 by means of bolts 306. The inner positioning block 302 can be removed separately. An inner positioning groove 303 is provided on the outer end surface of the inner positioning block 302. The inner positioning groove 303 contacts the guide vane 2. Furthermore, a plurality of balls 305 are movably mounted on the groove wall of the inner positioning groove 303. The balls 305 form point contact with the guide vane 2. When the outer positioning block 401 drives the outer end of the guide vane 2 to rotate, the inner end of the guide vane 2 applies force to the inner positioning block 302, causing the upper positioning seat 301 to rotate a corresponding angle. The inner positioning groove 303 and the guide vane 2 are clearance-fitted, and the inner positioning groove 303 only serves as a limit.

[0059] As shown in Figure 1, it consists of two turbine bases 1 and two guide vanes evenly distributed between the turbine bases 1.

[0060] When the turbine base is first placed on the assembly base 403, the manipulator grabs the guide vane 2 and places it on the turbine base.

[0061] When placing, place the inner end surface of the guide vane 2 close to the inner positioning groove 303, first perform preliminary positioning on the inner end surface of the guide vane 2, and then

[0062] The rod 405 moves in the groove 404, causing the outer positioning block 401 to move toward the outer end surface of the guide vane 2. The height of the guide vane 2 is greater than the outer positioning block 401.

[0063] The height of the block 401 is convenient for the robot to grab until the outer end surface of the guide vane 2 is stuck in the outer positioning groove 304, the rubber pad 417 and

[0064] The outer end surface of the guide vane 2 is tightly fitted, the outer end surface of the guide vane 2 is fixed, and the rotating motor 419 drives the outer positioning block 401 to rotate a certain angle

[0065] After the guide vane 2 is rotated to a certain angle by the external positioning block 401, the contact surface between the guide vane 2 and the water cooling base 1 is adjusted.

[0066] Continue the operation, then take it out, and place another water-cooling machine base 1 on the assembly base 403, reverse the taken out guide vane and the water-cooling machine base so that the other end of the guide vane contacts the other water-cooling machine base, repeat the above operation to complete the assembly of the water-cooling machine base ring guide vane.

[0067] On the basis of the above-mentioned embodiment 1, in addition to positioning the guide vanes 2, the turbine base 1 also needs to be positioned during the assembly process to further improve the assembly quality of the turbine base ring guide vanes. A plurality of limit rods 409 are further installed on the assembly base 403, wherein two limit rods 409 form a group and are respectively located on the inner ring and outer ring of the limit base 403. The two limit rods 409 are in contact with the inner ring and outer ring of the turbine base 1. The limit rods 409 limit the position of the turbine base to prevent the turbine base from moving during assembly. Specifically, as shown in Figures 5 to 7, a circular hole 411 is provided on the assembly seat 403, and the circular hole 411 is located in the upper middle part of the assembly seat 403, so that when the limit rod 409 works, the position of the turbine seat can be limited. The circular hole 411 is located between two adjacent vertical poles 405, and bosses 412 are symmetrically provided in the circular hole 411. A dual-axis motor 413 is installed between the bosses 412. The motor rod of the dual-axis motor 413 is provided with a thread, and a threaded sleeve 414 is provided on the motor rod. The motor rod and the threaded sleeve 414 form a screw-nut transmission mechanism. The dual-axis motor 413 drives the motor rod to rotate, so the threaded sleeve 414 can move linearly along the motor rod. The threaded sleeve 414

[0068] The outer ring fixed sleeve is provided with a rotating sleeve 415, and connecting blocks 410 are installed at both ends of the rotating sleeve 415. A shaft is installed between the two connecting blocks 410. The shaft is located on one side of the threaded sleeve 414. The shaft is rotatably connected to the limit rod 409. As the threaded sleeve 414 moves linearly, the limit rod 409 connected to the threaded sleeve 414 moves linearly along the circular hole 411. The threaded sleeve 414 is on one side and the limit rod is on the other side.

[0069] A soft spring 416 is installed on the end face of 409. When the threaded sleeve 414 moves toward the inside of the circular hole 411, the limiting rod 409 is restricted by the circular hole 411, so that the limiting rod 409 is located horizontally in the circular hole 411. When the threaded sleeve 414 moves toward the outer end of the circular hole 411, when the threaded sleeve 414 moves to a certain position, the limiting rod 409 is completely located outside the circular hole 414. At this time, the soft spring 416 is used to prevent the limiting rod 409 from being located outside the circular hole 414.

[0070] The limiting rods 409 are in a vertical direction, so the two limiting rods 409 swing relative to each other, thereby fixing the inner ring and outer ring of the turbine base.

[0071] Furthermore, when the turbine base is fixed, in order to improve the centering of the turbine base and the assembly base 403, the assembly base 403

[0072] A vibrator 407 is also installed inside. The vibrator 407 is located above the dual-axis motor 413. Ejectors 408 are evenly distributed on the vibrator 413. The top of the ejector 408 passes through the assembly seat 403 and extends to the top of the assembly seat 403. The top of the ejector 408 contacts the bottom end surface of the turbine base 1. The vibrator 407 transmits the vibration force to the ejector 408. The turbine base is further fine-tuned through the ejector 408 so that the axis of the limit rod 409 located on the inner and outer rings of the turbine base and the threaded sleeve 404 are perpendicular to each other.

[0073] Example 3

[0074] On the basis of the above-mentioned embodiment 2, in addition to the assembly and positioning of the turbine seat ring guide vanes as shown in Figure 1, as shown in Figure 4, a lower concave cavity 406 is opened in the assembly seat 403, and the central intersection of the cross plate 402 is located in the lower concave cavity 406. A support column 5 is threadedly installed on the cross plate 402 to facilitate the detachable installation of the support column 5 and the assembly seat 403. The purpose of installing the support column 5 in a detachable manner is that when assembling the turbine seat ring guide vanes as shown in Figure 2, the support column 5 can be removed. Specifically, after the support column 5 and the upper positioning group 3 are removed, the turbine seat is placed on the assembly seat 403, and the threaded sleeve 414 is inserted into the circular hole 411.

[0075] The outer end moves so that the limit rod 409 is completely moved out of the circular hole 414, and the limit rod 409 is fixed in the vertical direction by the soft spring 416.

[0076] The inner and outer rings of the fixed turbine base are fixed, and at the same time, the vertical rod 405 moves in the groove 404, so that the outer positioning block 401 moves toward the turbine base 1.

[0077] The outer end face moves, and the outer positioning block 401 is pressed against the outer end face of the turbine base 1, completing the fixation of the turbine base 1. The multiple guide vanes are sequentially plugged into the turbine base 1 by the manipulator, and then other processes are carried out.

[0078] Furthermore, in order to facilitate the movement of the vertical rod 405, as shown in FIG10 , a driving group 6 is installed on the cross plate 402.

[0079] The drive group 6 is connected to the vertical rod 405. A through hole (not shown) is provided in the cross plate 402 and the assembly seat 403 for cooperating with the drive group 6. The drive group 6 includes a threaded slide 604. The bottom of the vertical rod 405 extends to the bottom of the groove 404 and is connected to the threaded slide 604. A drive motor 601 is installed at the bottom of the cross plate 402. The drive motor 601 is preferably a dual-spindle motor. A screw 602 is connected to the drive motor 601. The end of the screw 602 is sleeved with an end fixing bracket 605. The end fixing bracket 605 is connected to the cross plate 402. The threaded slide 604 is sleeved on the screw 602. The screw 602 is also sleeved with a step collar 603. The threaded slide 604 is located at the step.

[0080] The purpose of setting the step collar 603 and the end fixing frame 605 between the collar 603 and the end fixing frame 605 is to prevent the thread from

[0081] The slide 604 is separated from the threaded area of ​​the screw 602 , and the screw 602 is rotated by driving the motor 601 . The threaded slide 604 moves along the screw 602 , driving the vertical rod 405 to move in the groove 404 .

[0082] The working principle of the present invention is as follows: the bottom turbine base is placed on the assembly base 403, the dual-axis motor 413

[0083] The motor rod is driven to rotate, and the threaded sleeve 414 moves out of the circular hole 411, so that the limiting rod 409 is completely located outside the circular hole 414.

[0084] The soft spring 416 makes the limit rod 409 fix the inner and outer rings of the bottom turbine seat in the vertical direction, and the vibrator 407 works and transmits the vibration force to the ejector pin 408. The bottom turbine seat is further fine-tuned through the ejector pin 408 so that the axes of the limit rod 409 and the threaded sleeve 404 located on the inner and outer rings of the bottom turbine seat are perpendicular to each other; the manipulator grabs the guide vane 2, presses the inner end surface of the guide vane 2 against the inner positioning groove 303 and places it on the bottom turbine seat, first performs preliminary positioning on the inner end surface of the guide vane 2, drives the motor 601 to rotate the screw 602, and the threaded slide 604 moves along the screw 602, driving the vertical rod 405 to move in the groove 404, so that the outer positioning block 401 moves toward the outer end surface of the guide vane 2 until the outer end surface of the guide vane 2 is stuck in the outer positioning groove 304, and the rubber pad 417

[0085] The outer end surface of the guide vane 2 is tightly fitted to fix the outer end surface of the guide vane 2; the rotating motor 419 drives the outer positioning block 401 to rotate a certain

[0086] After the guide vane 2 is rotated to a certain angle by the external positioning block 401, the contact surface between the guide vane 2 and the bottom water cooling base is adjusted.

[0087] Perform subsequent operations, then remove it, and then place the top water cooling machine base on the assembly base 403, and then remove the guide vanes and the bottom water cooling machine base.

[0088] Assemble the base in reverse so that the other end of the guide vane contacts the top water-cooled base. Repeat the subsequent operations of the guide vane 2 and the contact surface of the bottom water-cooled base to complete the assembly of the water-cooled base ring guide vane.
