Description of reference numerals:
The device comprises a base 1, a support bolt 2, a threaded hole 3, a positioning column 4, a column 41, a cover 42, a three-point positioning device 43, a positioning pin 431, a pressure receiving block 432, a pressure receiving block 433, a fastening bolt 434, a pressure plate 5 and a workpiece 6.
Detailed Description
The present invention will be further described with reference to the accompanying drawings.
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail with reference to the accompanying drawings and the following detailed description. It should be understood that the detailed description and specific examples, while indicating the invention, are given by way of illustration only.
Referring to fig. 1-2, a center positioning tool for belt pulley support comprises a base 1, wherein a plurality of support bolts 2, threaded holes 3, positioning columns 4 and a pressing plate 5 are fixedly arranged on the base 1, the support bolts 2 are used for supporting a workpiece 6, the positioning columns 4 are located in through holes of the workpiece 6, and the pressing plate 5 is used for pressing the workpiece 6 through the matching of the bolts and the threaded holes 3. The positioning is firstly carried out through the positioning column 4, and then the fixing is carried out through the pressing plate 5.
In this embodiment, the positioning column 4 includes a hollow column 41, a cover 42 is disposed on the column 41, and a three-point positioning device 43 is disposed in the column.
Referring to fig. 3, the three-point positioning device 43 includes three positioning pins 431 equidistantly arranged, one end of each of the three positioning pins 431 penetrates through the sidewall of the cylinder, the other end of each of the three positioning pins 431 is fixedly provided with a semicircular pressure block 432, a pressing block 433 of a cone structure is arranged above the center of each of the three pressure blocks 432, the upper end of each of the pressing blocks 433 is provided with a fastening bolt 434, and the fastening bolt 434 is in threaded connection with the cover 42. The middle extrusion block 433 is driven to move downwards by rotating the locking bolt 434, and three pressure blocks 432 are synchronously extruded, namely three positioning pins 431 are synchronously extruded, so that the positioning pins 431 can extend out of the cylinder 41 to be clamped in the through hole of the workpiece 6, and the purpose of synchronous centering is achieved.
In this embodiment, the outer diameter of pressure receiving block 432 is larger than the inner diameter of the through hole through which positioning pin 431 passes, so that positioning pin 431 is not separated from cylinder 41.
