For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0045] like Figure 1-4As shown, an embodiment of the utility model provides an auxiliary device for assembling blades of a gas turbine, comprising an installation shell 1, wherein the installation shell 1 forms an installation cavity with a bottom plate 101, a first side wall 102 arranged at both ends of the bottom plate 101 in the length direction, and a second side wall 103 arranged at both ends of the bottom plate 101 in the width direction. The two first side walls 102, the two second side walls 103 and the bottom plate 101; wherein in order to achieve the clamping and fixing of the wheel shaft and the positioning and support of the blades, two clamping assemblies 2 are arranged in the installation cavity, and the two clamping assemblies 2 are respectively used to clamp the ends of the wheel shaft, and a support assembly 3 for placing the blades is arranged on the outer side wall of one end of the installation shell 1 in the width direction. In this embodiment, the support assembly 3 is installed on the second side wall 103, and the support assembly 3 can be moved along the length direction of the installation shell 1, so that the support assembly 3 can be moved to the side mounting position corresponding to the wheel shaft to position the blades in the mounting position. By means of the clamped axle, the blades can be installed on the outer wall of the axle; in order to be suitable for axles of different lengths, the two clamping assemblies 2 can be close to or far away in the length direction of the mounting shell 1, so that even for axles of different lengths, the two clamping assemblies 2 can still clamp the two ends of the axle to maintain stable clamping of the axle; because a plurality of blades need to be installed on the outer wall of the axle, and because the blades are positioned and placed on the support assembly 3, in order to ensure that the blades are stably installed on the side of the axle, a rolling element 26 in contact with the axle is provided on the clamping surface of the clamping assembly 2, and when the clamping assembly 2 clamps the end of the axle, it is actually clamped by the rolling element 26, so that the axle can also rotate when clamped, so that when a blade is installed on the side of the axle, by rotating the axle, the side wall of the axle without the blade installed is directed toward the blade on the support assembly 3, and then the blade is continued to be installed until the installation of the blade on the main shaft is completed. It should be noted that when installing the blades, the installed blades and the axle need to be supported to prevent the axle from rotating due to gravity when installing another blade, which makes it inconvenient to install the blades. In addition, the two clamping assemblies 2 are initially located at the two ends of the mounting housing 1 in the length direction, that is, the two clamping assemblies 2 are respectively located at the two first side walls 102.

[0046] Specifically, the clamping assembly 2 includes a guide frame 21, a first drive assembly 22, a second drive assembly 23, an upper clamping portion 24 and a lower clamping portion 25; wherein the guide frame 21 is located in the mounting shell 1 and can move along the length direction of the mounting shell 1, the first drive assembly 22 is mounted on the guide frame 21, the second drive assembly 23, the upper clamping portion 24 and the lower clamping portion 25 are mounted on the driving end of the first drive assembly 22, and the driving end of the first drive assembly 22 can move in the vertical direction, thereby driving the second drive assembly 23, the upper clamping portion 24 and the lower clamping portion 25 to move in the vertical direction, and at the same time, the second drive assembly 23 is used to drive the upper clamping portion 24 and the lower clamping portion 25 to move closer or farther in the vertical direction, so that it can be used to clamp axles of different outer diameters, and the first drive assembly 22 is used to make the central axes of axles of different outer diameters at the same height, so as to correspond to the height of the blades on the support assembly 3, so as to facilitate the installation of the blades on the outer side wall of the axle.

[0047] Moreover, a plurality of rolling elements 26 are arranged on the clamping surfaces of the upper clamping portion 24 and the lower clamping portion 25, so that when the upper clamping portion 24 and the lower clamping portion 25 clamp the wheel axle, and in order to ensure stable clamping of the wheel axle, at least two rolling elements 26 on the clamping surfaces of the upper clamping portion 24 and the lower clamping portion 25 are in contact with the outer wall of the wheel axle, so that the circumferential rotation of the wheel axle is ensured without position deviation, so that the wheel axle is stably clamped.

[0048] Specifically, in order to satisfy the requirement that the first driving component 22 drives the second driving component 23, the upper clamping part 24 and the lower clamping part 25 to move in the vertical direction, in the present embodiment, the first driving component 22 includes a first screw rod 221 and a first driving block 222. Correspondingly, a first sliding groove 214 is vertically arranged on the side wall of the guide frame 21 away from the adjacent first side wall 102, wherein one end of the first screw rod 221 passes through the first sliding groove 214 from top to bottom and is rotatably arranged at the bottom of the first sliding groove 214, the upper end of the first screw rod 221 passes through the upper side wall of the mounting shell 1 and is connected with a driving member 223, and the first screw rod 221 can be rotated by the driving member 223. Correspondingly, the first driving block 222 is threadedly connected to the first screw rod 221, and the second driving component 23, the upper clamping part 24 and the lower clamping part 25 are mounted on the first side wall 102. On a driving block 222, and the second driving assembly 23 is installed on the first driving block 222, and the driving end is vertically arranged, and one of the upper clamping part 24 or the lower clamping part 25 is connected to the driving end of the second driving assembly 23, and the other is arranged on the first driving block 222; thereby, by driving the second driving assembly 23, one of the clamping parts is relatively far away from or close to the other clamping part, so that the upper and lower clamping parts 25 clamp the end of the wheel axle; when the height of the wheel axle needs to be adjusted, it is only necessary to drive the driving member 223 to rotate the first screw rod 221, so that the first driving block 222 rises or falls, thereby driving the entire wheel axle end to rise or fall. It can be known that when adjusting the height of the wheel axle, it is necessary to make the two first driving assemblies 22 work at the same time, that is, the two first screw rods 221 rotate at the same time. Of course, the specific structure of the first driving assembly 22 is not limited to the combination of the above-mentioned first screw rod 221 and the first driving block 222, and should be included in the one that can make the driving end realize linear motion. The driving member 223 can be a round handle or a rotating motor.

[0049] Specifically, Figure 1 As shown, in this embodiment, the first driving block 222 includes a vertical plate, an upper mounting plate and a lower mounting plate. A sliding block is provided at the end of the vertical plate close to the guide frame 21. The sliding block is located in the first sliding groove 214 and is threadedly connected to the first screw rod 221. The upper mounting plate and the lower mounting plate are respectively horizontally mounted on the side walls of the vertical plate away from the guide frame 21, and have a certain distance. The second driving component 23 is mounted on the upper mounting plate, and the driving shaft faces downward. The upper clamping portion 24 is connected to the end of the driving shaft away from the second driving component 23, and the lower clamping portion 25 is mounted on the lower mounting plate; the second driving component 23 can be a linear motor.

[0050] Specifically, the upper clamping portion 24 and the lower clamping portion 25 each include a mounting shell 241. In order to adapt to the arcuate surface of the wheel axle as much as possible, the adjacent sides of the two mounting shells 241 are provided with arcuate surfaces, and a plurality of rolling elements 26 are evenly distributed on the arcuate surfaces. When working, the two arcuate surfaces are first moved away from each other, and then the end of the wheel axle is placed between the two arcuate surfaces, and then the two arcuate surfaces are brought closer together, so that the two arcuate surfaces clamp the wheel axle. At this time, at least two rolling elements 26 on each arcuate surface are in contact with the outer wall of the wheel axle, thereby fixing the end of the wheel axle. It can be imagined that a corresponding spherical groove is provided on the arc surface, and the rolling element 26 can be a ball, which is installed in the spherical groove, and the ball part protrudes outside the spherical groove, and in order to ensure that at least two rolling elements 26 on the clamping surfaces of the upper clamping part 24 and the lower clamping part 25 are in contact with the outer wall of the wheel shaft, the rolling elements 26 are symmetrical about the central axis of the arc surface, so that the wheel shaft and the side wall will at least contact the two rolling elements 26 in the middle of the arc surface. Moreover, in actual use, the outer diameter of the wheel shaft is not much different from the outer diameter of the arc surface, so that the clamped wheel shaft is located in the support space surrounded by the upper clamping part 24 and the lower clamping part 25.

[0051] Specifically, in order to realize the two clamping components 2 approaching or moving away from each other, two third driving components 4 are arranged on the installation shell 1, and the two third driving components 4 respectively drive the two clamping components 2 to move in the length direction of the installation shell 1, wherein the third driving component 4 includes a first driving motor 41 and a second screw rod 42, and correspondingly, a first slide plate 5 is arranged at the bottom of the installation shell 1 along its length direction, and the first slide plate 5 is provided with a second sliding groove 51, that is, the second sliding groove 51 is opened on the upper end surface of the bottom plate 101, and the bottom of the second screw rod 42 is rotatably arranged in the second sliding groove 51, and the first driving motor 41 is arranged at the installation shell 1 close to the corresponding clamping component 2. The guide frame 21 is mounted on the outer wall of the housing 1, and its driving shaft passes through the outer wall of the housing 1 and is connected to the second screw rod 42 through a coupling, and the lower end of the guide frame 21 is threadedly connected to the second screw rod 42; thus, the first driving motor 41 rotates, which can drive the second screw rod 42 to rotate, and the second screw rod 42 drives the guide frame 21 to move along the length direction of the housing 1; thus, when in use, it is only necessary to start the first driving motor 41, and the two first driving motors 41 respectively drive the two second screw rods 42 to rotate, and the two second screw rods 42 correspondingly drive the two clamping assemblies 2, that is, drive the two guide frames 21 to move at the same time, so that the two guide frames 21 are moved closer or farther away. It can be known that the two first driving motors 41 are respectively installed on the outer walls of the housing 1 that are close to each other, that is, on the first side walls 102 that are close to each other, so when the two first driving motors 41 are started, the two guide frames 21 driven by the first screw rod 221 will naturally move closer or farther away.

[0052] Preferably, in order to realize the stable movement of the guide frame 21 in the length direction of the mounting shell 1, two second driving blocks 213 are provided at the lower end of the guide frame 21, wherein one second driving block 213 is threadedly connected to the second screw rod 42 provided in the corresponding second sliding groove 51, and the other second driving block 213 is slidably provided in the other second sliding groove 51, that is, there is a second screw rod 42 and two second driving blocks 213 in the same second sliding groove 51 (one for each of the two guide frames 21), wherein the second screw rod 42 can be provided in two ways, the first being that the second The length of the screw rod 42 is half the length of the second sliding groove 51, one second driving block 213 is threadedly connected to the second screw rod 42, and the other only slides in the second sliding groove 51. The second type is that the length of the second screw rod 42 is greater than the length of the second sliding groove 51, and the bottom end of the second screw rod 42 is rotatably mounted on the bottom end of the second sliding groove 51, and the length of the thread on it is half the length of the second screw rod 42. At this time, one second driving block 213 is threadedly connected to the second screw rod 42, and the other second driving rod is slidably mounted on the bare rod of the second screw rod 42 and can slide in the second sliding groove 51 at the same time. Therefore, during the movement of the guide stand 21, the two sliding blocks slide in the two second sliding grooves 51 respectively, so that the guide stand 21 can move stably in the length direction of the mounting shell 1.

[0053] Preferably, in order to reduce the weight of the guide frame 21, so that the movement of the guide frame 21 is more stable and the structure is more streamlined, in the present embodiment, the guide frame 21 includes a guide plate 211 and two support rods 212 arranged at the lower end of the guide plate 211, wherein the angle between the two support rods 212 is an obtuse angle, and the two second driving blocks 213 are respectively installed at the lower ends of the two support rods 212, so that the entire guide rod is in a "human" shape, and the first sliding groove 214 is vertically arranged on the side wall of the guide plate 211.

[0054] Specifically, a second slide plate 6 is provided on the outer side wall of one end of the mounting shell 1 in the width direction, that is, the second slide plate 6 is provided on the second side wall 103, and a third sliding groove 61 is provided on the second slide plate 6, and the third sliding groove 61 is provided along the length direction of the mounting shell 1. Correspondingly, the support assembly 3 includes a support frame, and the support frame is used to place the blades, and for the positioning and installation of the blades, the lower end of the support frame is slidably installed in the third sliding groove 61. During installation, the support frame is first slid on the third sliding groove 61 to the blade installation position, and then the blade is placed on the support frame and installed on the wheel axle accordingly.

[0055] Specifically, the support frame includes a vertical movable plate 31, a first clamping plate 32 and a second clamping plate 33. The lower end of the vertical movable plate 31 is slidably installed in the third sliding groove 61; the first clamping plate 32 and the second clamping plate 33 are spaced apart in the vertical direction, and one end is installed on a side wall of the vertical movable plate 31 facing the wheel axle, and the other end forms a clamping opening 34 adapted to the cross-section of the blade. The blade can be placed in the clamping opening 34, with the installation end of the blade facing the wheel axle, and the free end of the blade passes through the clamping opening 34 and is located in the area between the first clamping plate 32 and the second clamping plate 33, thereby realizing the positioning and clamping of the blade.

[0056] Specifically, in order to fix the support frame after movement, the support assembly 3 also includes a fixing member 35. Correspondingly, a threaded hole is provided at the lower end of the vertical movable plate 31, and the fixing frame is threadedly connected to the threaded hole. When the support frame needs to be fixed, it is only necessary to tighten the fixing member 35 and make the fixing member 35 abut against the second slide plate 6.

[0057] Specifically, in order to facilitate the movement of the support frame, a second drive motor is also provided on the outer wall of the mounting shell 1, and a third screw rod is installed in the corresponding third sliding groove 61. The driving shaft of the second drive motor passes through the outer wall of the mounting shell 1 and is connected to the end of the third screw rod through a coupling.
