DETAILED DESCRIPTION

[0019] The following is combined with Figure 1-5 The embodiments of the present utility model are described in detail.

[0020] A positioning device for the inner ring of a wheel hub comprises a base 1 and a fixed platform 2 arranged on the upper part of the base 1. The base 1 is square and the fixed platform 2 is round. A plurality of sliding grooves 3 are opened on the upper part of the fixed platform 2. The sliding grooves 3 are arranged in the radial direction of the fixed platform 2. A movable block 4 and a clamping block 5 are arranged in the sliding groove 3. The clamping block 5 can slide in the sliding groove 3 along the direction of the sliding groove 3. The movable block 4 is located on the outer side of the clamping block 5. A spring 6 is connected between the movable block 4 and the clamping block 5. A threaded seat 9 is arranged at a position corresponding to the sliding groove 3 on the outer periphery of the fixed platform 2. An adjusting screw 8 is connected to the inner thread of the threaded seat 9. A hand wheel 10 is connected to the outer end of the adjusting screw 8. The inner end of the adjusting screw 8 extends into the sliding groove 3 and is rotatably connected to the movable block 4.

[0021] The inner ring of the wheel hub is placed on the fixed platform 2, and is clamped and fixed from the outside or inside by the clamping block 5 under the action of the spring 6. The adjusting screw 8 is driven to rotate by the hand wheel 10, so as to adjust the position of the movable block 4 in the sliding groove 3, and the movable block 4 drives the clamping block 5 to move in the sliding groove 3, so as to adjust the initial position of the clamping block 5, which can be applied to fix the inner rings of wheel hubs with different diameters, thereby increasing the scope of application.

[0022] Preferably, inclined surfaces 7 are provided on both the inner and outer sides of the upper portion of the clamp block 5. When the inner ring of the wheel hub contacts the clamp block 5, the inclined surfaces 7 are used to guide the clamp block 5, thereby conveniently pushing the clamp block 5 to the outer or inner side of the inner ring of the wheel hub.

[0023] Preferably, a mounting ring 11 is provided on the upper part of the fixed platform 2, a gear ring 12 is rotatably provided in the mounting ring 11, a support frame 13 is provided on the fixed platform 2 at a position outside the mounting ring 11, a screw rod 14 is rotatably connected between the support frame 13 and the fixed platform 2, a screw rod nut block 15 is provided on the screw rod 14, a pressure block 16 is installed on the screw rod nut block 15, a driven gear 23 is connected to the screw rod 14, and the driven gear 23 is meshed with the gear ring 12, and a driving motor is provided on the upper part of the fixed platform 2, and the driving motor is connected to the driving gear 22, and the driving gear 22 is meshed with the gear ring 12. The driving motor drives the driving gear 22 to rotate, and the driving gear 22 drives the gear ring 12 to rotate in the mounting ring 11, and the gear ring 12 then drives each meshing driven gear 23 to rotate synchronously. The driven gear 23 drives the screw rod 14 to rotate to control the screw rod nut block 15 to move downward, so that the pressure block 16 is pressed on the inner ring of the wheel hub, thereby fixing the inner ring of the wheel hub in the vertical direction. A sponge block, a rubber block, etc. can be installed at the bottom of the pressing block 16 to avoid direct contact between the pressing block 16 and the inner ring of the wheel hub, thereby protecting the inner ring of the wheel hub and preventing the inner ring of the wheel hub from being crushed.

[0024] Preferably, the screw nut block 15 and the pressure block 16 are connected by a fixing bolt 17, and the fixing bolt 17 is set through the pressure block 16 and the screw nut block 15. The pressure block 16 and the screw nut block 15 are relatively fixed by the fixing bolt 17, so that the relative position between the pressure block 16 and the screw nut block 15 can be adjusted when the fixing bolt 17 is loosened. When placing and removing the inner ring of the wheel hub on the fixing table 2, the pressure block 16 can be rotated to a vertical state with the screw nut block 15, so as to prevent the pressure block 16 from affecting the removal of the inner ring of the wheel hub.

[0025] Preferably, the pressure block 16 is provided with a through hole 18, a fixing pin 20 is inserted into the through hole 18, and the screw nut block 15 is provided with a fixing hole 19 and a fixing hole 21 that match the fixing pin 20, and the angle between the fixing hole 21 and the fixing hole 19 is 90 degrees. When the pressure block 16 and the screw nut block 15 are in a straight line, the fixing pin 20 passes through the through hole 18 and is inserted into the fixing hole 19 to limit the pressure block 16 and the screw nut block 15. When the pressure block 16 and the screw nut block 15 are perpendicular to each other, the fixing pin 20 passes through the through hole 18 and is inserted into the fixing hole 21 to limit the pressure block 16 and the screw nut block 15.

[0026] Preferably, a plurality of sliding grooves 3 are evenly distributed on the fixed platform 2, and the number of the sliding grooves 3 is at least three, so as to realize the centering of the clamping block 5 on the inner ring of the wheel hub, making the positioning of the inner ring of the wheel hub more accurate.

[0027] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
