[0003] The wire wheel hub is light in weight and has good resilience, but generally an inner tube and an outer tube are installed outside the rim, otherwise it is easy to leak air, affecting the use effect.

[0004] At the same time, due to the installation requirements of the steel wire, the wire hub separates the rim and the hub, and a steel wire needs to be installed between the two. At this time, it is necessary to ensure the concentricity of the connection between the two, and a specific installation mechanism is required. However, there is no such structure now. Generally, after manual installation is completed, it is necessary to use a micrometer to check and then gradually correct it, which is very troublesome and inefficient. Utility model content:

It can fix the wheel hub and the hub part in position, and then install the steel wire. During the installation process, the circular runout of the wheel hub during the manufacturing process is constantly detected, so that there is no need for subsequent correction.

[0017] For example, see Figures 1 to 3As shown, a retro wheel production and correction instrument comprises a machine table 10, a rotating sleeve 20 is fixed in the middle of the top surface of the machine table 10, a rotating shaft 30 is movably connected to the rotating sleeve 20 through a bearing, the top end of the rotating shaft 30 extends out of the top end of the rotating sleeve 20 and is fixed with a horizontal rotating plate 31, an annular protrusion 32 extending upward is formed on the edge of the horizontal rotating plate 31, a plurality of annular steps 33 extending in a stepped manner are formed on the inner side wall of the annular protrusion 32, a central through hole is formed in the middle of the horizontal rotating plate 31, a central rod body 40 is inserted into the central through hole, the lower part of the central rod body 40 is clamped on the inner side wall of the central through hole of the rotating shaft 30, the upper part of the central rod body 40 extends out of the top surface of the horizontal rotating plate 31 and is fixed with a height adjustment block 50 and a positioning cone sleeve 60, and the positioning cone sleeve 60 is located above the height adjustment block 50;

[0018] A lower annular portion is formed in the middle of the bottom surface of the height adjustment block 50, and the bottom end of the plug-in through hole formed in the middle of the height adjustment block 50 extends out of the bottom surface of the lower annular portion, while an upper annular portion is formed in the middle of the top surface of the positioning cone sleeve 60, and the top end of the middle through hole of the positioning cone sleeve 60 extends out of the top surface of the upper annular portion. The side walls of the upper and lower annular portions are formed with threaded through holes extending radially inward. After the height adjustment block 50 and the positioning cone sleeve 60 are inserted into the center rod body 40, a fixing bolt can be screwed into the threaded through hole, and the end of the screw rod of the fixing bolt extends out of the inner end of the corresponding threaded through hole and presses against the outer side wall of the center rod body 40, thereby fixing the height adjustment block 50 or the positioning cone sleeve 60. The connection method is the same as the method in which some existing connecting components are fixed by fixing bolts, which will not be described in detail here. When connected, the concentricity of the central axis of the positioning cone sleeve 60 and the center rod body 40 will have a certain deviation, but the deviation is small and within the allowable range, and does not affect subsequent calibration and use.

[0019] Furthermore, the rim 100 to be processed is placed on the horizontal rotating plate 31, the bottom of the rim 100 is inserted into the corresponding annular step 33, the bottom outer wall of the rim 100 is pressed against the inner wall of the corresponding annular step 33, and the bottom surface of the rim 100 is pressed against the bottom surface of the corresponding annular step 33. A main circular protrusion 35 is formed in the middle of the top surface of the horizontal rotating plate 31, and movable positioning blocks 34 are fixed on the top surfaces of the left, right, front and rear parts of the main circular protrusion 35. The top surface of the movable positioning block 34 is formed with a plurality of elongated mounting grooves, and the bottom surface of the elongated mounting grooves is formed with waist-shaped through grooves, which correspond to the corresponding screw holes formed on the top surface of the main circular protrusion 35. The screw portion of the connecting bolt is inserted into the corresponding waist-shaped through groove and screwed in the corresponding screw hole, and the bottom surface of the rotating portion of the connecting bolt is pressed against the bottom surface of the corresponding elongated mounting groove.

[0020] By loosening the connecting bolts, the position of the movable positioning block 34 can be moved and the distance of the outer end thereof extending out of the outer wall of the main circular protrusion 35 can be adjusted. That is, when the outer wall of the bottom of the rim 100 is inserted into different annular steps 33, all connecting bolts can be loosened to move the position of the movable positioning block 34 and the distance of the outer end thereof extending out of the outer wall of the main circular protrusion 35 can be adjusted to ensure that the outer wall of the side plate portion 341 (whose outer wall is a conical wall surface) extending upward formed on the outer edge of the movable positioning block 34 is pressed against the lower inner wall of the rim 100 to fix the rim 100, and then all corresponding connecting bolts can be tightened.

[0021] Furthermore, a sleeve-shaped hub 200 is pressed against the top surface of the height adjustment block 50, and a positioning cone sleeve 60 is inserted into the hub 200. The outer side wall of the positioning cone sleeve 60 is a conical side wall with a larger diameter at the upper end and a smaller diameter at the lower end. The lower part of the positioning cone sleeve 60 is inserted into the through hole in the middle of the bottom plate of the hub 200, and the lower outer side wall of the positioning cone sleeve 60 is pressed against the upper inner side wall of the through hole in the middle of the bottom plate of the hub 200.

[0022] Furthermore, a connecting seat 11 is fixed on the top surface of the right side of the machine 10, a moving block 12 is installed on the connecting seat 11, a vertical rod 13 is fixed on the top surface of the moving block 12, a micrometer fixing rod 14 is installed on the upper and middle parts of the vertical rod 13, and a micrometer 15 is installed on the end of the micrometer fixing rod 14;

[0023] The detection end of the upper micrometer 15 rests on the outer side wall of the rim 100 below the upper rim of the rim 100 , and the detection end of the middle micrometer 15 rests on the outer side wall of the rim 100 above the lower rim of the rim 100 .

[0024] The detection ends of the two micrometers 15 detect whether the concentricity of the rim 100 meets the requirements when it rotates during the processing. It can continuously detect its circular runout during the processing, so that no correction is required after the installation is completed, which greatly reduces the processing difficulty and processing time and improves the processing efficiency. The micrometer fixing rod 14, the vertical rod 13 and the micrometer 15 are all existing conventional structures and components, and the adjustment method is conventional, so it will not be described in detail.

[0025] Furthermore, an adjustment groove extending left and right is formed in the middle of the top surface of the connecting seat 11, and the moving block 12 is inserted into the adjustment groove. The front and rear side walls of the moving block 12 are close to or close to the front and rear inner walls of the adjustment groove. A plurality of waist-shaped grooves 121 are formed on the moving block 12, and the waist-shaped grooves 121 correspond to the connecting screw holes formed on the bottom surface of the adjusting groove. The screw portion of the fixing bolt is inserted into the corresponding waist-shaped groove 121 and screwed in the corresponding connecting screw hole. The bottom surface of the moving block 12 is pressed against the bottom surface of the adjusting groove, and the top surface of the moving block 12 is pressed against the bottom surface of the rotating portion of the fixing bolt.

[0026] The distance between the two micrometers 15 and the rim 100 can be adjusted by loosening all the fixing bolts, moving the moving block 12, and then loosening the fixing bolts, which can meet the adjustment needs.

[0027] When the present embodiment is used, the rim 100 is first installed, and its bottom end is inserted into the corresponding annular step 33. Then, as in the above-mentioned method, the outer wall of the upwardly extending side plate portion 341 formed on the outer edge of the moving positioning block 34 is pressed against the lower inner wall of the rim 100 to fix the rim 100.

[0028] Then, loosen the fixing bolts of the height adjustment block 50 so that it can move up and down along the central rod body 40 to ensure that the position of the hub 200 subsequently placed thereon corresponds to the position of the rim 100. It can be detected by a depth gauge. After the detection and adjustment are completed, the hub 100 to be processed can be placed on the top surface of the height adjustment block 50, and then the positioning cone sleeve 60 is sleeved on the central rod body 40 and is in the hub 100. The lower part of the positioning cone sleeve 60 is inserted into the through hole in the middle of the bottom plate of the hub 200, and the lower outer wall of the positioning cone sleeve 60 is pressed against the upper inner wall of the through hole in the middle of the bottom plate of the hub 200, so as to realize the positioning and centering of the hub 200. Then, tighten the fixing bolts connected to the positioning cone sleeve 60 to complete the installation.

[0029] Then, the steel wire can be installed between the hub 200 and the rim 100. When the rim 100 is rotated, the rotating shaft 30 is also driven to rotate. The circular runout at the corresponding position of the rim 100 is constantly detected by two micrometers 15. If the circular runout is small or basically non-existent, it means that the rim 100 meets the installation requirements and the processing quality of the hub manufacturing is good and meets the requirements. This makes it unnecessary to make subsequent corrections, which is very convenient and greatly improves the processing efficiency.

[0030] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
