The slewing bearing includes an inner ring and an outer ring, and the inner ring is provided with a hole to be installed. The bolt installation device includes a workbench, a rotating seat and a rotation-stopping mechanism. The workbench is provided with a pressing mechanism. The pressing mechanism has a downward pressing end that is telescopic in the vertical direction, and the downward pressing end is aligned with one of the holes to be installed up and down. The rotating seat is used to fix the inner ring of the slewing bearing, and the rotating seat is provided with a plurality of clearance holes, and the diameter of the clearance holes is larger than the diameter of the hole to be installed. The rotation-stopping mechanism is arranged on the workbench and is located on one side of the rotating seat. The rotation-stopping mechanism has a locking state connected with the outer ring to limit the rotation of the outer ring, and also has an unlocking state separated from the outer ring. In the locking state, the rotating seat drives the inner ring to rotate so that each hole to be installed is aligned with the downward pressing end in sequence. The bolt installation device provided by the utility model can shorten the bolt installation time and improve work efficiency.

[0004] Similar to the above application, there are still the following shortcomings: when installing the automobile wheel hub bolts, the bolts will become loose when positioning the automobile wheel hub. Utility Model Content

[0005] The utility model discloses an automobile production bolt installation device, which aims to solve the technical problem that when installing the automobile wheel hub bolt, the bolt will be loose when it is positioned at the automobile wheel hub.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A bolt installation device for automobile production comprises a positioning plate, a soft pad is provided on the outer surface of the positioning plate, a fixing frame is fixedly connected to the outer side surface of the positioning plate, a fixing block is fixedly connected to the side of the fixing frame away from the positioning plate, a track ring is fixedly connected to the side of the fixing block away from the fixing frame, a positioning mechanism is slidably connected to the outer surface of the track ring, the positioning mechanism comprises a sliding sleeve, the sliding sleeve is slidably connected to the inner ring of the track ring, a rotating plate is provided on the outer surface of the sliding sleeve, and a positioning tube passes through the outer surface of the rotating plate; a clamping mechanism is fixedly connected to the inner cavity of the fixing frame, the clamping mechanism comprises a threaded ring, the threaded ring is fixedly connected to the inner wall of the fixing frame, and a threaded rod is threadedly connected to the inner cavity of the threaded ring.

[0008] By setting the track ring, the positioning mechanism can be limited, so that the bolt can rotate after being clamped by the positioning mechanism, so that the bolt can be aligned with the hole of the wheel hub. The setting of the sliding sleeve can cooperate with the track ring, so that the rotating plate drives the positioning tube to rotate stably. By setting the clamping mechanism, the device can be connected to the outer surface of the wheel hub and can be tightly connected to the wheel hub to prevent the bolt from tipping over or loosening when the bolt is installed.

[0009] In a preferred solution, the number of the positioning tubes is two, and the two positioning tubes symmetrically penetrate the rotating plate, and a magnet is arranged in the inner cavity of the positioning tube. The number of the magnets is several, and the several magnets are evenly distributed.

[0010] By arranging the magnet, the bolt can be adsorbed, so that the bolt can be positioned in the inner cavity of the positioning tube.

[0011] In a preferred embodiment, the number of the clamping mechanisms is two, and the two clamping mechanisms are symmetrical with the center of the orbital ring as the center, the end of the threaded rod is fixedly connected to the limiting sleeve, the inner cavity of the limiting sleeve is rotatably connected to a rotating ball, the outer surface of the rotating ball is fixedly connected to a fixing column, the end of the fixing column away from the rotating ball is fixedly connected to an extrusion plate, the outer surface of the threaded ring is provided with a fixing plate, the outer surface of the fixing plate is fixedly connected to a first spring sheet, the end of the first spring sheet is provided with a first placement plate, the side of the extrusion plate close to the fixing column is fixedly connected to a second spring sheet, the end of the second spring sheet is fixedly connected to a second placement plate, the upper surface of the second placement plate is provided with an extrusion strip, and the end of the extrusion strip away from the second placement plate is fixed to the upper surface of the first placement plate.

[0012] By setting up two clamping mechanisms, the mechanism can be tightly connected to the wheel hub. The setting of the limit sleeve can cooperate with the rotating ball, so that when the threaded rod rotates, the rotating ball can not rotate. The setting of the fixed column and the extrusion plate can contact the inner wall of the automobile wheel hub. The setting of the first spring piece can be deformed when it is squeezed, so that the first placement plate at the end is tilted. The setting of the second spring piece can be deformed when it is squeezed, so that the second placement plate at the end is tilted. The setting of the extrusion strip can squeeze the inner wall of the automobile wheel hub when the first placement plate and the second placement plate are tilted, so as to achieve the fixing of the device.

[0013] As can be seen from the above, a bolt installation device for automobile production has the following improvements and advantages compared with the prior art:

[0014] First, by setting the track ring, the positioning mechanism can be limited, so that the bolt can rotate after being clamped by the positioning mechanism, so that the bolt can be aligned with the hole of the wheel hub.

[0015] Secondly, by providing a clamping mechanism, the device can be connected to the outer surface of the wheel hub and can be tightly connected to the wheel hub to prevent the bolts from tipping over or loosening when the bolts are installed. BRIEF DESCRIPTION OF THE DRAWINGS

A rotating plate 62 is provided on the outer surface of the sliding sleeve 61, and a positioning tube 63 passes through the outer surface of the rotating plate 62. The setting of the sliding sleeve 61 can cooperate with the track ring 5, so that the rotating plate 62 drives the positioning tube 63 to produce stable rotation; a clamping mechanism 7 is fixedly connected to the inner cavity of the fixing frame 2, and the clamping mechanism 7 includes a threaded ring 71, and the threaded ring 71 is fixedly connected to the inner wall of the fixing frame 2. A threaded rod 72 is threadedly connected to the inner cavity of the threaded ring 71. By setting the clamping mechanism 7, the device can be connected to the outer surface of the wheel hub, and can be tightly connected to the wheel hub to prevent the bolts from tipping over or loosening when the bolts are installed.

[0026] Reference Figure 3 In a preferred embodiment, there are two positioning tubes 63, and the two positioning tubes 63 symmetrically penetrate the rotating plate 62. A magnet 64 is arranged in the inner cavity of the positioning tube 63. There are several magnets 64, and the magnets 64 are evenly distributed. The arrangement of the magnet 64 can adsorb the bolt, so that the bolt can be positioned in the inner cavity of the positioning tube 63.

[0027] Reference Figure 4 and Figure 5In a preferred embodiment, the number of the clamping mechanisms 7 is two, and the two clamping mechanisms 7 are symmetrical with the center of the track ring 5 as the center. By setting up two clamping mechanisms 7, the mechanism can be tightly connected to the wheel hub. The end of the threaded rod 72 is fixedly connected to a limiting sleeve 79, and a rotating ball 710 is rotatably connected to the inner cavity of the limiting sleeve 79. The setting of the limiting sleeve 79 can cooperate with the rotating ball 710, so that when the threaded rod 72 rotates, the rotating ball 710 can not rotate.

The setting of the extrusion strip 76 can squeeze the inner wall of the automobile wheel hub when the first placement plate 75 and the second placement plate 77 are tilted, thereby achieving the fixing work of the device.

[0028] Working principle: When in use, the operator inserts the clamping mechanism 7 into the fixed gap of the automobile wheel, and then rotates the threaded rod 72. During the rotation of the threaded rod 72, the extrusion plate 712 at the end moves toward the fixed plate 73, thereby causing the first spring piece 74 and the second spring piece 78 to deform, and finally causing the extrusion strip 76 to tilt up and squeeze the inner wall of the automobile wheel hub, thereby achieving the effect of fixing the device on the outer surface of the wheel hub. After the device and the wheel hub are positioned, the operator places the bolts to be installed into the inner cavity of the positioning tube 63, and then rotates the rotating plate 62 to make the sliding sleeve 61 slide on the outer surface of the track ring 5 until the positioning tube 63 is aligned with the hole in the wheel hub, and then the bolts can be tightened.
