Description

Technical Field

[0001] The utility model relates to the field of automobile manufacturing, in particular to a grinding device for automobile wheel hub processing. Background Art

[0002] The automobile wheel hub, also known as the wheel hub, is an important part of the automobile. It connects the brake drum or brake disc, wheel disc and half shaft. Its main function is to bear weight and provide precise guidance for the rotation of the wheel hub. In the production process of automobile wheel hubs, grinding is a key step, which involves fine processing of the wheel hub surface to ensure that its smoothness and dimensional accuracy meet the requirements. Before grinding, the wheel hub needs to be fixed first to prevent the wheel hub from shifting during grinding, resulting in poor grinding effect. However, due to the inconsistent wheel hub size of each model, different fixing equipment is required to fix the wheel hub during grinding, which increases the cost of purchasing grinding equipment, and each wheel hub size needs to be classified before matching the grinding equipment, which increases the step of wheel hub classification. For this reason, we propose a grinding device for automobile wheel hub processing. Utility Model Content

[0026] The adjustment assembly is mounted on two sets of ground rods 5 and is used to fix wheels of different sizes.

[0027] The fixing assembly is installed on the adjusting assembly to prevent the adjusting assembly from being displaced when the wheel hub is polished.

[0028] An arc groove 7 is provided on the top of the support frame 6 , and the wheel hub 8 is movably inserted into the arc groove 7 , and then the wheel rim side of the wheel hub 8 is placed in the arc groove 7 on the support frame 6 .

[0029] The adjusting assembly includes an adjusting spring 4, an adjusting support frame 10 and an arc plate 11. The tops of the two groups of ground rods 5 are slidably connected with the adjusting support frame 10. The top of the adjusting support frame 10 is fixedly provided with an integrated and vertical arc plate 11. One side of the arc plate 11 is fixedly connected with the adjusting spring 4 above the two groups of ground rods 5. When using this device, first pull the arc plate 11 toward one side of the side plate 3 so that the arc plate 11 drives the adjusting support frame 10 to slide on the two groups of ground rods 5. When the adjusting support frame 10 slides, the adjusting spring 4 is compressed by the arc plate 11 to begin to deform and shorten.

[0030] The side of the arc plate 11 facing away from the adjusting spring 4 is in an arc shape and is completely fitted with the outer wall of the hub 8. The side of the arc plate 11 facing away from the arc shape is fixedly connected to one end of the adjusting spring 4, and the other end of the adjusting spring 4 is fixedly connected to one side of the side plate 3. Then the arc plate 11 is loosened, and the elasticity of the side plate 3 is used to make the arc plate 11 slide on the two groups of ground rods 5 through the adjusting support frame 10 until the arc-shaped side of the arc plate 11 is fitted with the outer wall of the wheel rim on the hub 8.

[0031] The fixing assembly includes an adjusting rod 12, a cross bar 13 and an adjusting seat 14. A horizontal adjusting rod 12 is fixedly provided on one side of the arc plate 11, and a cross bar 13 is fixedly provided on the end position of the adjusting rod 12 away from the arc plate 11. An adjusting seat 14 is slidably connected between the arc plate 11 and the cross bar 13 on the adjusting rod 12. The adjusting seat 14 is slid toward one side of the adjustment support frame 10, and the cross bar 13 on the adjusting rod 12 prevents the adjusting seat 14 from sliding out of the adjusting rod 12.

[0032] The fixing assembly also includes a rod head 15 and a hole 16. The adjustment seat 14 is fixedly provided with a rod head 15 perpendicular to the adjustment seat 14 on one side corresponding to the adjustment support frame 10. A hole 16 adapted to the rod head 15 is opened on one side of the adjustment support frame 10. The adjustment seat 14 drives the rod head 15 to be inserted through the hole 16 into a group of limiting holes 9 when the adjustment support frame 10 is stopped, so as to fix the position of the adjustment support frame 10. The adjustment seat 14 drives the rod head 15 to be inserted through the hole 16 into a group of limiting holes 9 when the adjustment support frame 10 is stopped, so as to fix the position of the adjustment support frame 10, thereby preventing the wheel hub grinding device 2 from shaking or shifting in position when grinding the wheel hub 8. By rotating the wheel hub 8 in the arc groove 7 on the support frame 6 and on the arc plate 11, other positions of the wheel hub 8 can be ground.

[0033] A plurality of groups of horizontal and equidistantly arranged limiting holes 9 are provided on one side of one group of ground rods 5 corresponding to the holes 16, and the rod head 15 is movably inserted into one group of limiting holes 9 through the holes 16. By inserting the rod head 15 into the limiting holes 9, the position of the adjusting support frame 10 can be fixed to prevent the adjusting support frame 10 from sliding on the two groups of ground rods 5 during the process of grinding the wheel hub 8 by the wheel hub grinding device 2, thereby causing the wheel hub 8 to shake, resulting in a poor grinding effect on the wheel hub 8.

[0034] Working principle: When using the device, first pull the arc plate 11 toward one side of the side plate 3 so that the arc plate 11 drives the adjustment support frame 10 to slide on the two sets of ground rods 5. When the adjustment support frame 10 slides, the adjustment spring 4 is compressed by the arc plate 11 and begins to deform and shorten. Then, place one side of the wheel rim on the hub 8 in the arc groove 7 on the support frame 6, and then release the arc plate 11. The elasticity of the side plate 3 is used to make the arc plate 11 slide on the two sets of ground rods 5 through the adjustment support frame 10 until the arc-shaped side of the arc plate 11 is aligned with the outer side of the wheel rim on the hub 8. The wall is fitted, and the adjustment seat 14 is slid toward one side of the adjustment support frame 10. The cross bar 13 on the adjustment rod 12 prevents the adjustment seat 14 from sliding out of the adjustment rod 12, so that the adjustment seat 14 drives the rod head 15 to pass through the hole 16 and insert into a group of limit holes 9 when the adjustment support frame 10 stops. The position of the adjustment support frame 10 can be fixed to prevent the wheel hub grinding device 2 from shaking or position shifting when grinding the wheel hub 8. By rotating the wheel hub 8 in the arc groove 7 on the support frame 6 and on the arc plate 11, other positions of the wheel hub 8 can be ground.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
