Detailed Description

In order to clearly explain the technical features of the present solution, the present solution is explained by the following detailed description.

As shown in fig. 2 and 3, the utility model comprises a fixing base 1, a positioning base 2 installed on the fixing base 1 and a positioning sleeve 3 sleeved outside the positioning base 2. The positioning base 2 is connected with the fixing base 1 through bolts, and in the embodiment, the number of the bolts is four, so that the positioning base 2 and the fixing base 1 are fixed firmly.

Set up the second locating pin 7 that is used for the first locating pin 5 that band pulley locating pin hole 4 detected and is used for band pulley locking hole 6 to detect on location base 2, in this embodiment, first locating pin 5 is five, second locating pin 7 is one, five first locating pins 5 and five locating pin hole 4 positions one-to-one of band pulley, and second locating pin 7 corresponds with the locking hole 6 position of band pulley.

First locating pin 5 diameter is less than the diameter of locating pin hole 4, makes things convenient for first locating pin 5 to insert in the locating pin hole 4 of examining the work piece, and 7 diameters of second locating pin are less than the diameter of locking hole 6, make things convenient for second locating pin 7 to insert in the locking hole 6 of examining the work piece.

Set up round location boss 8 in location base 2 bottom, set up fixed pin 9 on unable adjustment base 1, set up the jack that corresponds with fixed pin 9 on position sleeve 3, fixed pin 9 corresponds inserts in the jack and position sleeve 3 and location boss 8 interference fit.
