Technical Field

[0001] The utility model belongs to the technical field of automobile wheel hub clamps, and more specifically, particularly relates to a clamp for processing a front wheel hub. Background Art

[0002] The wheel hub is the rotating part of the wheel core connected to the inner profile of the tire by a column, that is, the metal part that supports the center of the tire and is mounted on the shaft. It is also called a rim, steel rim, wheel, or tire bell. There are many types of wheel hubs depending on the diameter, width, molding method, and material. A clamp is usually used during processing to prevent the wheel hub from moving.

[0003] Based on the above, the inventors have discovered the following problems: most of the existing wheel hub clamps usually place the wheel hub directly on an operating table, and use the clamp to clamp the wheel hub from the outside, while the wheel hub processing requires not only processing of both sides but also processing of the outer ring of the wheel hub, and the external clamping requires adjusting the position to process the outer ring, and placing the wheel hub directly on the operating table requires turning it over, which is inconvenient to use.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a clamp for front wheel hub processing is provided, in order to achieve a more practical purpose. Utility Model Content

[0008] Furthermore, the third support rod is arranged in an X shape, and the middle portion of the third support rod is threadedly connected to the threaded rod.

[0009] Furthermore, slide grooves are provided on all four sides of the middle part of the operating table, and the four lifting rods are slidably connected to the four slide grooves respectively, and the height value of the lifting rod is greater than the height value of the first connecting rod.

[0010] Furthermore, a second connecting rod is fixed to one side of the middle portion of the inner side wall of the support block, a second limiting rod is fixed to the top of the second connecting rod, and the second limiting rod is located on one side of the second connecting rod close to the support block.

[0025] As attached Figure 1 To Attachment Figure 4 As shown:

[0026] The utility model provides a clamp for processing a front wheel hub, comprising an operating table 1, wherein support legs 2 are fixed at four corners of the bottom of the operating table 1, a placement groove 3 is opened in the middle of the top of the operating table 1, driven racks 7 are slidably connected on both sides of the placement groove 3, first connecting rods 8 are fixed to the tops of the opposite ends of the two driven racks 7, a second supporting rod 9 is fixed to the top of the first connecting rod 8, a first limiting rod 10 is fixed to the top of the second supporting rod 9, a first supporting rod 4 is fixed to the middle of the top of the operating table 1, a first servo motor 5 is fixed to the middle of the first supporting rod 4, a driving gear 6 is fixed to the power output end of the first servo motor 5, a fourth supporting rod 17 is fixed to the middle of the bottom of the operating table 1, a second servo motor 18 is fixed to the middle of the fourth supporting rod 17, a threaded rod 19 is fixed to the power output end of the second servo motor 18, a lifting rod 12 is movably connected through the middle of the operating table 1, a supporting block 13 is fixed to the top of the lifting rod 12, and a third supporting rod 16 is fixed to the bottom of the lifting rod 12.

[0027] Among them, the third support rod 16 is arranged in an X shape, and the middle part of the third support rod 16 is threadedly connected to the threaded rod 19. The threaded rod 19 is driven to rotate by controlling the second servo motor 18. The threaded rod 19 rotates in the middle part of the third support rod 16, thereby controlling the lifting and lowering of the third support rod 16, driving the horizontal height of the top of the lifting rod 12 to change.

[0028] Among them, slide grooves 11 are opened all around the middle of the operating table 1, and four lifting rods 12 are slidably connected to the four slide grooves 11 respectively. The height value of the lifting rod 12 is greater than the height value of the first connecting rod 8. The lifting rod 12 slides up and down in the slide groove 11. The lifting rod 12 is pre-raised to a horizontal height greater than the first connecting rod 8. At this time, the front wheel hub can be placed above the support block 13 at the top of the lifting rod 12. After adjusting the position of the first connecting rod 8, the lifting rod 12 is controlled to descend so that the front wheel hub falls on the top of the second support rod 9.

[0029] Among them, a second connecting rod 14 is fixed to one side of the middle part of the inner wall of the support block 13, and a second limiting rod 15 is fixed to the top of the second connecting rod 14.

After the front wheel hub is placed on the top of the second support rod 9, the driving gear 6 is driven to rotate by controlling the first servo motor 5, and then the two driven racks 7 are driven to move. The two driven racks 7 simultaneously drive the two first connecting rods 8 to move to both ends, so that the first limit rod 10 can be tightly fitted with the inner ring of the front wheel hub.

[0032] The specific usage and function of this embodiment are as follows:

[0033] In the present invention, firstly, the second servo motor 18 is controlled to drive the threaded rod 19 to rotate, and the threaded rod 19 rotates in the middle of the third support rod 16, thereby controlling the lifting of the third support rod 16, driving the horizontal height of the top of the lifting rod 12 to change, and the lifting rod 12 is preliminarily raised to a horizontal height greater than the first connecting rod 8. At this time, the front wheel hub can be placed above the support block 13 at the top of the lifting rod 12, and the first servo motor 5 is controlled to drive the driving gear 6 to rotate, thereby driving the two driven racks 7 to move, and the two driven racks 7 simultaneously drive the two first connecting rods 8 to move to both ends, so that the second support rod 9 is located at the bottom of the wheel hub. The lifting rod 12 is continued to be controlled to descend, so that the front wheel hub falls on the top of the second support rod 9. After the front wheel hub falls on the top of the second support rod 9, the lifting rod 12 is continued to be controlled to descend, so that the second limit rod 15 can touch the top of the front wheel hub, and the top of the front wheel hub is squeezed and limited. Subsequently, the first servo motor 5 is controlled to drive the driving gear 6 to rotate, thereby driving the two driven racks 7 to move. The two driven racks 7 simultaneously drive the two first connecting rods 8 to move to both ends, so that the first limit rod 10 can be tightly fitted with the inner ring of the front wheel hub. Finally, the wheel hub can be processed, and one side of the outer ring of the wheel hub and the upper and lower sides can be processed.
