DETAILED DESCRIPTION

[0028] The technical scheme in the embodiment of the utility model will be described clearly and completely in combination with the drawings in the embodiment of the utility model.

[0029] For example Figures 1-6As shown, the impeller welding fixture in the embodiment comprises a base plate 1 and an impeller table 2. A plurality of shaft seats are arranged on the base plate 1, the center line of the shaft seats coincides with the center line of the impeller table 2, and the impeller table 2 is rotatably connected with the shaft seats. When the impeller table 2 is fixed on the impeller table 2, the impeller table 2 can be adjusted by rotation to change its position, so that the operator or staff does not need to move around for operation, which can provide convenience for welding operation and speed up the processing efficiency of impeller welding maintenance process. In order to ensure that the impeller table 2 can remain stationary during welding processing, the impeller welding fixture further comprises a pressing and limiting mechanism 3 and an adjusting mechanism 4. The pressing and limiting mechanism 3 is controlled by the adjusting mechanism 4, that is, the pressing and limiting mechanism 3 controls whether the impeller table 2 is pressed to control whether the impeller table 2 can rotate.

[0030] Further, the impeller welding fixture can further comprise a support table 5, which is arranged on the ground. Support columns are welded at the four corners of the base plate 1, and the lower end of the support column is fixedly connected with the table top of the support table 5. The impeller table 2 is arranged at a position about one meter away from the ground by the support table 5, so as to facilitate the operator to process.

[0031] Firstly, as shown in the drawings, Figure 2 The impeller table 2 comprises a support disc 21 and a center piece 22. The support disc 21 is located above the base plate 1, and the center piece 22 is rotatably connected with the shaft seat and fixed at the center of the support disc 21. When the center piece 22 rotates, the support disc 21 will not move eccentrically. Further, the shaft seat comprises a boss 11 fixed on the base plate 1, a limiting cover 12 is fixed on the boss 11 by bolts, and a receiving cavity is formed in the boss 11. The center piece 22 comprises a shaft part and a disc part. The shaft part is fixedly connected with the support disc 21, and the disc part is located in the receiving cavity.

[0032] In the above structure, the upper surface of the disc part of the center piece 22 is in contact with the limiting cover 12, and the lower surface of the disc part of the center piece 22 is in contact with the inner bottom wall of the receiving cavity. When the disc part of the center piece 22 or the support disc 21 is subjected to upward or downward pressure, the rotation of the disc part of the center piece 22 is limited. Since the upper surface of the support disc 21 needs to place the impeller of the impeller feeder, the upward pressure is applied to the support disc 21.

[0033] In addition, the support disc 21 is provided with an impeller clamping part 23 for clamping the impeller.

[0034] The structure of the above-mentioned impeller clamping part 23 can be various. Since it is not the focus of the present application, a structure of the impeller clamping part 23 is given for easy understanding, as shown in the drawings. Figure 2As shown, the support disc 21 is provided with a plurality of waist holes, for example, four groups, the impeller clamping component 23 includes clamping blocks 231 slidingly connected in the waist holes, and the outer side of the clamping blocks 231 is integrally connected with side wing plates 232 slidingly connected to the upper surface of the support disc 21, and the side wing plates 232 are provided with fixing bolts for threaded connection with the support disc 21. It should be noted that a plurality of bolt holes are arranged linearly beside the waist holes, and the bolt holes are matched with the fixing bolts. In this way, when the fixing bolts are screwed into the corresponding bolt holes, the impeller clamping component 23 can clamp the impeller of the corresponding size specification.

[0035] In order to control whether the support disc 21 is subjected to upward pressure and in turn control whether the support disc 21 is limited to rotate, the pressing and limiting mechanism 3 in the application includes two groups of sliding frames 31, a vertical sliding column 32 is fixed on the sliding frame 31, a pressing block 33 is slidingly connected to the outer side of the sliding column 32, two groups of sliding blocks 34 are slidingly connected in any one group of sliding frames 31, that is, the number of sliding blocks 34 is four groups, and the two groups of sliding blocks 34 are distributed in the two groups of sliding frames 31, a push plate 35 is hinged between the two groups of sliding blocks 34 and the pressing block 33, that is, the two sides of the push plate 35 are hinged with the sliding blocks 34 and the pressing block 33, respectively. In this way, when the two groups of sliding blocks 34 in any one group of sliding frames 31 move towards or away from each other, the pressing block 33 can slide up or down along the sliding column 32. In order for the operator to complete the work of moving the two groups of sliding blocks 34 in the sliding frame 31 towards or away from each other, the adjusting mechanism 4 is arranged at the bottom of the base plate 1 and is used to drive the two groups of sliding blocks 34 to move towards or away from each other, so that the pressing block 33 can slide up and down along the sliding column 32.

[0036] The structure of the above-mentioned adjusting mechanism 4 can be various, and two specific structures of the adjusting mechanism 4 are provided in this embodiment.

[0037] In the first embodiment, as shown in Figures 2-4 The adjusting mechanism 4 includes a displacement frame one 41, the cross section of the displacement frame one 41 is rectangular, a sliding groove is formed in the bottom side of the displacement frame one 41, a rotating column one 42 is rotatably connected in the sliding groove, two groups of threads with opposite thread directions are arranged on the outer side of the rotating column one 42, two groups of nut seats 43 are slidingly connected in the sliding groove and are threadedly connected with the rotating column one 42 through the two groups of threads, and the bottom of each of the two groups of nut seats 43 is provided with a connection strip one fixed with the corresponding sliding block 34.

[0038] It should be noted that one end of the front surface of the rotating column one 42 is fixed with a hand wheel one for the operator to hold and rotate.

[0039] When designed in this way, the operator can rotate the rotating column 42 by rotating the hand wheel 1, and the two sets of nuts 43 will move towards or away from each other under the influence of the two sets of threads with opposite thread directions. For example, when the two sets of nuts 43 move towards each other, the two sets of sliding blocks 34 will move towards each other through the transmission of the connecting bar 1, and the two push plates 35 will push the pressing block 33 to move upwards and limit the support disc 21. In this way, it can be ensured that the support disc 21 will not rotate randomly during welding processing. When the support disc 21 is not pressed tightly by the pressing block 33, the support disc 21 can be rotated through the central part 22. That is, the impeller table 2 can change its position through rotational adjustment, so that the operator or staff does not need to move around to work, which can provide convenience for welding operation and speed up the processing efficiency of the impeller welding and maintenance process when this impeller welding clamp is applied.

[0040] In Example Two, as shown in Figure 5 and 6 The adjusting mechanism 4 includes a displacement frame 2 44, a transmission space is arranged in the displacement frame 2 44, a rotating column 2 45 is rotatably connected in the transmission space, a first bevel gear is assembled at one end of the rotating column 2 45, a second bevel gear is engaged at the bottom of the first bevel gear, a shaft column 46 is assembled at the center of the second bevel gear and is rotatably connected in the transmission space, the top end of the shaft column 46 penetrates through the displacement frame 2 44 and is assembled with a drive gear 47, a rack 48 is engaged on the left and right sides of the drive gear 47, and the bottom of the rack 48 is fixed with a connecting bar 2 49, which is fixedly connected with the corresponding two sets of sliding blocks 34.

[0041] It should be noted that the front end of the rotating column 2 45 is fixed with a hand wheel 2 for the operator to hold and rotate.

[0042] When designed in this way, the operator can rotate the rotating column 2 45 by rotating the hand wheel 2, which drives the first bevel gear to rotate, and then drives the second bevel gear to rotate the shaft column 46 and the drive gear 47. When the drive gear 47 rotates, the two racks 48 will move towards or away from each other because the two racks 48 are arranged towards each other, and the two connecting bars 2 49 will drive the two sliding blocks 34 in the same sliding frame 31 to move towards or away from each other, and the pressing block 33 can slide upwards or downwards. In this way, the pressing block 33 can complete the work of pressing or not pressing the support disc 21. When the pressing block 33 moves upwards and presses the support disc 21, it can be ensured that the support disc 21 will not rotate randomly during welding processing. When the support disc 21 is not pressed tightly by the pressing block 33, the support disc 21 can be rotated through the central part 22. That is, the impeller table 2 can change its position through rotational adjustment, so that the operator or staff does not need to move around to work, which can provide convenience for welding operation and speed up the processing efficiency of the impeller welding and maintenance process when this impeller welding clamp is applied.

[0043] The above merely is the preferred specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited to this, any skilled person in the technical field according to the technical scheme and the utility model concept of the present utility model is equivalent to replace or change within the technical range disclosed by the present utility model, and should be covered in the protection scope of the present utility model.
