The technical solution of the present application is further described by the following embodiments with reference to fig. 1.

Referring to fig. 1, the present application provides a technical solution: a sprocket measuring tool comprising a sprocket chuck 9, the sprocket chuck 9 being for securing a sprocket to be measured, the form of the sprocket chuck 9 not being limiting in this application. For ease of describing the measurement tool in this application, the present embodiment employs a cylindrical sprocket chuck 9. Measuring tool still includes measuring mechanism, and measuring mechanism is located one side of sprocket chuck 9, and measuring mechanism includes dipperstick 1 and adjustment mechanism, and dipperstick 1 is used for measuring the sprocket, and adjustment mechanism is used for adjusting the accuracy in order to improve dipperstick 1 survey data to the position of dipperstick 1.

The adjusting mechanism comprises an adjusting slide rail 2, a first hand screwing bolt 4, a second hand screwing bolt 5, a fixed seat 3 and a plurality of fixing bolts 6. Fixing base 3 is the setting of rectangle platelike, and fixing base 3 can be dismantled and connect in the side of sprocket chuck 9, and is concrete, and a plurality of fixing bolt 6 all runs through fixing base 3 and with sprocket chuck 9 threaded connection, in this embodiment, the quantity of fixing bolt 6 sets up to four, and four fixing bolt 6 are located the four corners edge of fixing base 3 respectively. In addition, an avoiding opening is formed in the fixed seat 3 so that the chain wheel to be measured can be clamped or released by the adjusting chain wheel chuck 9 conveniently. Can dismantle with sprocket chuck 9 through making fixing base 3 be connected, not only be favorable to changing different sprocket chuck 9 so that sprocket chuck 9 centre gripping not unidimensional sprocket, improved measuring tool's suitability, be favorable to increasing measuring tool's portability moreover.

Adjust slide rail 2 and fix 3 and slide and be connected to adjust slide rail 2 and slide along the axial lead direction of sprocket chuck 9, it is specific, be provided with two sets of stoppers 7 on the fix 3, two sets of stoppers 7 set up along the axial lead direction interval of sprocket chuck 9. Every stopper 7 of group includes stopper 7 that two L appear, and two stoppers 7 symmetry set up and two stoppers 7 enclose jointly with fixing base 3 and close formation second sliding groove, promptly in this embodiment, two sets of stoppers 7 enclose jointly and close formation two second sliding grooves, adjust slide rail 2 and two second sliding grooves cooperation of all sliding for adjust slide rail 2 and can slide along the axial lead direction of sprocket chuck 9. The end of the second hand-operated bolt 5 penetrates through one limiting block 7, the second hand-operated bolt 5 is in threaded connection with the limiting block 7, and the end of the second hand-operated bolt 5 is abutted to the adjusting slide rail 2. When the reading is needed, the second hand is rotated to screw the bolt 5, so that the end part of the second hand is tightly abutted to the adjusting slide rail 2, the sliding of the adjusting slide rail 2 can be limited, the stability during the measurement is improved, and the reading is convenient for a worker.

Dipperstick 1 is located the one end of adjusting 2 ascending length directions of slide rail, and dipperstick 1 is along the radial sliding of sprocket chuck 9, and is specific, and dipperstick 1's cross-section is the T font, adjusts 2 ascending one end of length directions of slide rail and has also seted up the first groove that slides of T shape, dipperstick 1 and the first cooperation that slides of sliding groove for dipperstick 1 can follow the radial sliding of sprocket chuck 9. The tip of first hand bolt 4 runs through and adjusts slide rail 2 to first hand bolt 4 and the regulation slide rail 2 threaded connection, the tip and the dipperstick 1 butt of first hand bolt 4. When needs the reading, twist bolt 4 through rotatory first hand, make the tip of twisting bolt 4 on the first hand support tightly with dipperstick 1 to restricted the sliding of adjusting slide rail 2, improved the stability when measuring, the staff of being convenient for carries out the reading.

One side that dipperstick 1 kept away from first sliding groove tank bottom is provided with first scale (not shown in the figure), adjusts to be provided with on the slide rail 2 with first scale matched with second scale (not shown in the figure), through comparing first scale and second scale, can realize sprocket root radius or addendum radius's measurement. One end integrated into one piece that dipperstick 1 is close to sprocket chuck 9 axial lead has measurement needle 8, and the cross sectional area of measuring needle 8 is less than dipperstick 1's cross sectional area, and the one end that dipperstick 1 was kept away from to measurement needle 8 is provided with the curved surface, is favorable to stretching into in the gullet of small-size sprocket to realize dipperstick 1 to the measurement of small-size sprocket.

The working principle is as follows: when the root circle radius of sprocket is measured to needs, at first with the sprocket of awaiting measuring prefixed to sprocket chuck 9, then install measuring mechanism on sprocket chuck 9, adjust dipperstick 1 afterwards, make dipperstick 1 align with the tooth root center of sprocket, locking sprocket chuck 9 afterwards, make sprocket chuck 9 fix the sprocket centre gripping firm, then the position of slide rail 2 is adjusted in the adjustment, make dipperstick 1 and sprocket transversely align, then screw up the second hand-operated bolt 5, adjust dipperstick 1 afterwards, make the tooth root butt of dipperstick 1 and sprocket, then screw up first hand-operated bolt 4, read the root circle radius of sprocket according to first scale and second scale at last, thereby the measurement of the root circle radius of sprocket has been accomplished.

To sum up, this sprocket measuring tool, through setting up fixed sprocket and dipperstick 1, utilize fixed sprocket to fix the back with the sprocket that awaits measuring, recycle dipperstick 1 and measure the size of sprocket, especially root circle radius and addendum circle radius, the one end that makes dipperstick 1 carries out the butt with the sprocket, later on first scale on the comparison dipperstick 1 and the second scale on the adjusting part, can record the root circle radius and the addendum circle radius of sprocket, the device is simple portable, it is difficult to the accurate problem of partial size measurement with the sprocket when measuring to the sprocket to have solved the scene.
