In the figure: 1. the screening machine comprises a side plate binding face, 2 sieve beam spacing positioning holes, 3 fixing screw rods, 4 fixing nuts, 5 gaps, 6 long sides, 7 short sides, 8 kidney-shaped holes, 9 locking nuts, 10 sieve machine side plates, 11C-shaped beams and 12 notches.

Detailed Description

Referring to fig. 1-6, a C-shaped beam 11 positioning tool of a sieving machine, two sides of the positioning tool are side plate binding surfaces 1, a plurality of sieve beam spacing positioning holes 2 are uniformly arranged on the positioning tool along the distribution direction of sieve beams, fixing screws 3 are arranged on the sieve beam spacing positioning holes 2, the fixing screws 3 penetrate through the positioning tool and are screwed with fixing nuts 4, and gaps 5 for the notches 12 of the C-shaped beam 11 to enter are reserved between the fixing nuts 4 and the positioning tool. The size of the positioning tool and the sieve beam spacing positioning holes 2 are determined according to the width of a sieving machine and the installation size of a sieve plate, and the precision can be ensured by numerical control machining; the side plate binding surface 1 is abutted against the side plate 10 of the screening machine to be used as a reference to ensure the accurate positions of all the screen beams, wherein the screen beams are C-shaped beams 11. The positioning tool is designed according to a certain width, the purpose is to reserve a welding working space for the sieve beam and the support piece, meanwhile, the sieve beam cannot be bent too much in the adjacent space range of the tube beam, and the size precision of the beam distance can be guaranteed. In order to relieve progress pressure, a plurality of positioning tools can be installed simultaneously according to field conditions, the whole screen surface is integrally positioned by the positioning tools, and the mode of installing a screen surface supporting beam by the integral frame type greatly improves the installation quality and the screen surface transformation efficiency.

In order to guarantee the location precision and the location frock installation precision of sieve roof beam, therefore, when needing to guarantee curb plate binding face 1 and the laminating of sieve machine curb plate 10, location frock and sieve machine curb plate 10 mutually perpendicular, it is the rectangle to fix a position the frock at best, thereby guarantee that its long limit 6 and minor face 7 are the vertical relation, again set up sieve roof beam interval locating hole 2 on the long limit 6 of rectangle, and the minor face 7 of rectangle is curb plate binding face 1, when fixing a position, its long limit 6, a plane is constituteed to minor face 7 and sieve machine curb plate 10 two liang, and guaranteed mutually perpendicular between the two planes. After all the C-shaped beams 11 and the positioning tool are fixed by the fixing bolts and the fixing nuts 4, the horizontal and vertical of all the C-shaped beams 11 can meet the requirements in this way. While the gap 5 between the fixing screw 3 and the width of the notch 12 of the C-beam 11 serves as a reasonable accuracy margin.

In the process of fastening by using the bolt, the outer edge of the fixing nut 4 is close to the inner walls of the two sides of the C-shaped beam 11, so that the fixing nut 4 in the C-shaped beam 11 does not rotate along with the bolt, and the purpose of fastening the angle steel and the C-shaped beam 11 is achieved. The positioning in this way can compensate the deformation caused by bending and twisting of the C-shaped beam 11, and plays a decisive role in improving the positioning precision.

When positioning, the side plate binding surface 1 is bound with the side plate 10 of the sieving machine, therefore, the size of the positioning tool is just consistent with the inner diameter size between the two side plates of the sieving machine, the positioning tool is very difficult to place in the sieving machine, the long side 6 and the short side 7 of the positioning tool are detachably connected through bolts, the short side 7 is provided with a kidney-shaped hole 8, the short angle steel keeps a distance of 5mm with the side plate 10 of the sieving machine, the rectangular tool can conveniently enter and exit the sieving machine, the size is adjusted through the kidney-shaped hole 8, the side plate binding surface 1 is close to the side plate 10 of the sieving machine, the horizontal position of the long side 6 is found through the right-angled relation between the long side 6 of the rectangle and the short side 7, after all the placing positions of the C-shaped beams 11 are determined, the short side 7 is closely located and locked with the side plate 10 of the sieving machine, and all the angle steels and the C-shaped beams 11 are fixed through bolts.

Wherein, a locking nut 9 is screwed on the rod part of the fixing screw rod 3 between the head part of the fixing screw rod 3 and the positioning tool.

In order to facilitate processing and manufacturing, the long edge 6 and the short edge 7 of the positioning tool are both made of angle steel. The angle steel of location frock can be equilateral angle steel also can be other angle steels, and the structure that this scheme provided the location frock is not limited to specific manufacturing material and specification.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that changes may be made in the embodiments and/or equivalents thereof without departing from the spirit and scope of the utility model.
