As shown in fig. 1-4, the utility model discloses an auxiliary clamping device for detecting a half axle gear, which comprises a support 1, wherein the support 1 is fixedly arranged on a fixed base 2, a mandrel 3 is arranged on the support 1, the mandrel 3 is conical, one end of the mandrel 3 with a large diameter is connected with the support 1, and one end of the mandrel 3 with a small diameter is suspended. 3 periphery of dabber is provided with a plurality of spouts 5 along its length direction, it is provided with a plurality of gauge sticks 4 to slide in

spout

5, 4 outer walls of gauge stick with 3 outer wall laminating of dabber. The measuring rod 4 is cylindrical, and the plurality of measuring rods 4 are identical in shape and size.

When not in use, the measuring rod 4 can not slide off the mandrel. In use, the dipstick 4 drops into the splines 14 of the side gear 13. Through setting up measuring stick 4 in spout 5, when emboliaing half shaft gear 13, the relative position of a plurality of measuring sticks 4 on the same circumference of dabber 3 is fixed, need not earlier manual fixed a plurality of measuring sticks 4, slowly penetrates cover half shaft gear 13 on measuring stick 4 from the little one end of dabber 3 diameter again, operation labour saving and time saving. By providing a tapered spindle 3, this can accommodate side gears 13 of different sizes.

Further, the number of the measuring rods 4 is preferably 3, and the side gear 13 can be well fixed. The more preferable technical scheme is that the three measuring rods 4 are uniformly distributed on the periphery of the mandrel 3.

The connection mode between the mandrel 3 and the measuring rod 4 is as follows: a sliding block 6 is arranged in the sliding groove 5, the sliding block 6 can slide back and forth in the sliding groove 5, and one end, far away from the sliding groove 5, of the sliding block 6 is connected with the measuring rod 4. That is, the slide groove 5 and the slide block 6 are provided to slidably connect the measuring rod 4 and the spindle 3. In order to prevent the measuring bar 4 from sliding out of the sliding groove 5, the sliding groove 5 is closed close to the end with the small diameter of the mandrel 3.

The preferred scheme is that the periphery of the measuring rod 4 is provided with a groove corresponding to the sliding block 6, one end of the sliding block far away from the sliding groove 5 is inserted into the groove, the measuring rod 4 is detachably connected with the sliding block 6, and the measuring rods 4 with different sizes can be replaced according to requirements.

In order to prevent the sliding block 6 from falling from the sliding groove 5, one end of the sliding block 6 connected with the sliding groove 5 can be arranged to be T-shaped, inverted L-shaped and the like, and the sliding groove 5 is arranged to be in a corresponding shape. Or, the shape of the connecting end of the sliding block 6 and the sliding groove 5 is arbitrary, the core shaft 3 is made of cast iron, steel and iron materials, and then the magnet is arranged at one end, close to the sliding groove 5, of the sliding block 6, so that the measuring rod 4 is adsorbed on the outer wall of the core shaft 3.

When the measuring rod device is used, in order to fix the position of the measuring rod 4 on the outer wall of the mandrel 3, the measuring rod 4 is kept still when the half axle gear 13 is sleeved in, the sliding groove 5 is T-shaped, a long rod 7 with an I-shaped cross section is arranged at one end, with the diameter being large, of the mandrel 3 in the sliding groove 5, one end of the long rod 7 abuts against the measuring rod 4, and the other end of the long rod penetrates through and extends out of the support 1. The position of the measuring rod 4 on the outer wall of the mandrel 3 is fixed by fixing the position of the long rod 7 in the sliding groove 5. Specifically, the long rod 7 is provided with a through hole 11 along the length direction thereof, a fixing bolt 12 is inserted into the sliding groove 5 through the through hole 11, and the fixing bolt 12 is screwed and fixed on the long rod 7, thereby fixing the position of the long rod 7 in the sliding groove 5.

Further, when the side gear 13 detects radial run-out, the side gear 13 needs to be rotated, the end with the large diameter of the mandrel 3 is connected with the support 1 through the bearing 10, and the end with the large diameter of the mandrel 3 is fixedly connected with the output shaft 9 of the motor 8. During detection, the motor 8 drives the mandrel 3 to rotate.

The working process of the auxiliary clamping device for detecting the side gear comprises the following steps: according to side gear 13 and the size of its spline 14, tentatively judge the position of side gear 13 on dabber 3, unscrew fixing bolt 12, place stock 7 and measuring stick 4 in the position department of tentatively judging, screw up fixing bolt 12, fix stock 7 and measuring stick 4. The half shaft gear 13 is sleeved from the end, with the small diameter, of the mandrel 3, the measuring rod 4 falls into the spline 14 of the half shaft gear 13, and due to the fact that the mandrel 3 has the taper, the half shaft gear 13 can be automatically locked in the pushing process until the half shaft gear 13 cannot be pushed into the end, with the large diameter, of the mandrel 3, and then the half shaft gear 13 is fixed on the mandrel 3. During detection, the motor 8 is started, and the mandrel 3 drives the half axle gear 13 to rotate. After use, the side gear 13 is removed from the end of the spindle 3 having a smaller diameter.

The above-described embodiments are merely illustrative of the preferred embodiments of the present invention, and do not limit the scope of the present invention, and various changes, modifications, alterations, and substitutions which may be made by those skilled in the art without departing from the spirit of the present invention shall fall within the protection scope defined by the claims of the present invention.
