The clamping fixture 100 for the wind power generation gearbox shown in fig. 1 to 3 includes a bottom plate 10, a first supporting structure 20 fixed on the bottom plate 10, and a first positioning structure 30. The first supporting structure 20 is relatively arranged in the first direction a, the first positioning structure 30 is arranged on two sides of the first supporting structure 20 in the second direction B, the first positioning structure 30 includes a limiting plate 31 relatively arranged in the second direction B and clamping pieces 32 connected to the limiting plate 31 along the second direction B, and the clamping pieces 32 relatively arranged in the second direction B are close to or far away from each other to adjust a clamping distance between the clamping pieces 32. Referring to fig. 3, when the clamping fixture 100 is used, the gear box 80 is clamped and fixed, and then the gear box 80 is processed, specifically, the end portions 81 of the gear box 80 are respectively positioned between the two limiting plates 31 on the corresponding side of the bottom plate 10, the end portions 81 of the gear box 80 are respectively supported on the first supporting structures 20, and then the end portions 81 of the gear box 80 are clamped and fixed by adjusting the clamping distance between the clamping pieces 32.
In the embodiment, the base plate 10 has a length direction and a width direction, for example, the length direction of the base plate 10 is defined as a first direction a, and the width direction of the base plate 10 is defined as a second direction B, that is, the second direction B is horizontally perpendicular to the second direction a.
In order to improve the stability of the support of the gear box 80, the first support structure 20 includes two first support blocks 21, and the two first support blocks 21 are arranged right and left in the second direction B. Preferably, the first supporting blocks 21 are symmetrically arranged with respect to the horizontal longitudinal axis C of the base plate 10.
In the present embodiment, the stopper plate 31 is vertically fixed to the base plate 10. The fixing method between the stopper plate 31 and the base plate 10 may be, for example, a method of connecting the stopper plate 31 to the base plate 10 by connecting the connecting plate 311, integrally connecting the bottom of the stopper plate 31 to the connecting plate 311, and fixing the connecting plate 311 to the base plate 10 by a connecting member (not shown). In order to enhance the stability of the limiting plate 31, a reinforcing rib 312 is further disposed outside the limiting plate 31.
In this embodiment, the clamping member 32 is a screw, the screw penetrates through the limiting plate 31 from the outer side of the limiting plate 31 to the inner side of the limiting plate 31 along the second direction B, and the distance between the ends of the two oppositely disposed screws is the clamping distance formed by the clamping member 32 in the second direction B. By rotating the screw, the end of the screw is brought closer to the horizontal longitudinal axis C of the base plate 10 to reduce the width of the clamping gap, thereby clamping the end 81 of the gear case 80 between the clamping members 32.
The clamping fixture 100 further includes at least two second positioning structures 40 fixed on the bottom plate 10, each second positioning structure 40 includes a supporting column 41 protruding upward from the bottom plate 10, and a pressing member 42 disposed at an upper end of the supporting column 41 and detachably connected to the supporting column 41. The pressing member 42 is configured to abut against an upper surface of the gear box 80 when the end portion 81 of the gear box 80 is clamped between the clamping members 32, so as to further fix the gear box 80 in the vertical direction of the clamping jig 100. By additionally arranging the second positioning structure 40, the clamping firmness of the clamping jig 100 in the vertical direction is enhanced.
In this embodiment, the second positioning structure 40 further includes a positioning connector 43, and the supporting column 41 and the pressing member 42 are detachably connected through the positioning connector 43. For example, during installation, the end 81 of the gear box 80 is clamped between the clamping members 32, then the lower surface of one end of the pressing member 42 abuts against the upper end surface of the supporting column 41, the lower surface of the other end of the pressing member 42 abuts against the upper surface of the edge of the gear box 80, and then the pressing member 42 is fixed relative to the bottom plate 10 in the vertical direction of the clamping fixture 100 by the positioning connection member 43. Since the lower surface of the gear box 80 is supported by the first supporting structure 20 and the lower surface of the pressing member 42 is abutted against the upper surface of the edge portion of the gear box 80, in the embodiment, it can be understood that the pressing member 42 is located at a height higher than that of the first supporting structure 20, that is, the supporting column 41 is higher than that of the first supporting structure 20.
The clamping fixture 100 further includes a limiting block 50 fixed to the bottom plate 10 and located on one side of the bottom plate 10 in the second direction B, so as to facilitate positioning of the gear box 80 in the second direction B when the gear box 80 is installed. In this embodiment, two limiting blocks 50 are disposed on the same side of the bottom plate 10 in the second direction B, and when the gear box 80 is installed, the gear box 80 is positioned in the second direction B, and then the end 81 of the gear box 80 is positioned, so that the clamping efficiency of the gear box 80 is further improved.
Further, the clamping fixture 100 further includes a second supporting structure 60 fixed on the bottom plate 10, a distance between the second supporting structure 60 and the center of the bottom plate 10 is smaller than a distance between the first supporting structure 20 and the center of the bottom plate 10, and a height of the second supporting structure 60 is smaller than a height of the first supporting structure 20. The second support structure 60 may further support the gearbox on the underside of the middle part of the gearbox.
The clamping fixture 100 further includes a third supporting structure 70 fixed on the bottom plate 10, a distance between the third supporting structure 70 and the center of the bottom plate 10 is smaller than a distance between the second supporting structure 60 and the center of the bottom plate 10, and a height of the third supporting structure 70 is smaller than a height of the second supporting structure 60. The second support structure 60 may further support the gearbox 80 on the underside of the middle part of the gearbox.
With regard to the arrangement of the second and third support structures 60 and 70, for example, in order to improve the support stability with respect to the middle portion of the gear case 80, the second support structure 60 is annularly arranged centering on the center point of the base plate 10, and the third support structure 70 is annularly arranged centering on the center point of the base plate 10.
According to the clamping jig 100 for the wind power generation gearbox, firstly, the two sides of the end part 81 of the gearbox 80 are limited through the limiting plates 31, meanwhile, the first supporting structure 20 is adopted to support the lower part of the end part 81 of the gearbox 80, and then the clamping distance between the clamping pieces 32 is adjusted to clamp and fix the two sides of the end part 81 of the gearbox 80, so that the clamping efficiency and the repeated positioning accuracy of the gearbox 100 are improved.
The above-listed detailed description is only a specific description of a possible embodiment of the present invention, and they are not intended to limit the scope of the present invention, and equivalent embodiments or modifications made without departing from the technical spirit of the present invention should be included in the scope of the present invention.
