[0032] When the pulley hub 13 is subjected to surface grinding, the pulley hub 13 is placed between two extension tubes 18, and the two extension tubes 18 are driven to approach each other and extend into the interior of the pulley hub 13 through the provided adjustment assembly, and the pulley hub 13 is clamped and fixed by the provided wedge block I25 and wedge block II26 to ensure the grinding stability of the pulley hub 13.

[0033] Specifically, the adjustment assembly includes two coaxially fixed adjustment screws 8 with opposite thread rotation directions. The adjustment screws 8 are coaxially fixed with the output shaft of the motor II10. Each adjustment screw 8 is threadedly sleeved with a sliding frame I9 that is slidably connected to the carrier frame 1, and the transmission sleeve 20 is rotatably mounted on the sliding frame I9. The elastic assembly includes a baffle 24 fixed on the extension tube 18, a rotating ring 35 is rotatably mounted on the sliding frame I9, a spring ring 22 is fixed between the rotating ring 35 and the baffle 24, and a clamping strip II36 slidably embedded in the transmission sleeve 20 is fixed to the inner wall of the extension tube 18.

[0034] Through the above arrangement, the motor II10 can drive the adjusting screw 8 to rotate, the adjusting screw 8 drives the sliding frame I9 to move, and the sliding frame I9 drives the transmission sleeve 20 and the rotating ring 35 to move. At this time, under the action of the spring ring 22, the baffle plate 24 drives the extension tube 18 to move, so that the extension tube 18 enters the inside of the pulley hub 13, and the inner and outer ends of the pulley hub 13 slide and abut against the wedge II26 and the wedge I25 respectively, and under the action of the push assembly, the wedge II26 and the wedge I25 are close to each other to clamp and fix the pulley hub 13.

[0035] Specifically, the push-pushing assembly is rotatably mounted on a push-pushing rotating plate 31 in the extension tube 18, one end of the push-pushing rotating plate 31 is in contact with the wedge block II26, and a torsion spring 34 is fixed between the push-pushing rotating plate 31 and the extension tube 18. The push-pushing assembly also includes an extension rod 49 that slides through the clamping block 23, one end of the extension rod 49 is fixed to the wedge block I25, and a sliding column 33 is fixed to the other end of the extension rod 49. A slideway 32 for sliding the sliding column 33 is provided on the push-pushing rotating plate 31, and a push-pushing plate 27 that is in contact with the push-pushing rotating plate 31 is fixed at the end of the transmission sleeve 20. An extension block 28 is fixed on the wedge block I25, a limit plate 30 is fixed on the clamping block 23, and a support spring 29 is fixed between the limit plate 30 and the extension block 28.

[0036] Through the above-mentioned arrangement, the transmission sleeve 20 drives the push plate 27 to slide toward the pulley hub 13, and the push plate 27 pushes the push rotating plate 31, and the push rotating plate 31 rotates and pushes the wedge block II26, so that the wedge block II26 moves toward the pulley hub 13 and abuts against it, and at the same time, the push rotating plate 31 drives the extension rod 49 to slide toward the extension tube 18 through the sliding column 33, and the wedge block I25 moves toward the pulley hub 13 and abuts against it. At this time, the wedge block I25, the wedge block II26 and the clamping block 23 realize stable and rapid clamping and fixing of the pulley hub 13, and the set motor I4 drives the drive shaft 19 to rotate, and the drive shaft 19 drives the transmission sleeve 20 to rotate through the clamping strip I21, and the transmission sleeve 20 drives the extension tube 18 to rotate through the clamping strip II36, thereby realizing the rotation of the pulley hub 13, and the pulley hub 13 rotates relative to the grinding assembly to realize the surface grinding of the pulley hub 13.

[0037] Example 2

[0038] See also Figure 1-9 On the basis of Example 1, in addition, the grinding assembly includes a vertical sleeve 39 vertically slidably mounted on the sliding frame II40, a vertical slide 47 vertically slidably mounted on the vertical sleeve 39, a grinding head 38 abutting against the pulley hub 13 is fixed at one end of the vertical slide 47, and a vertical spring 48 is fixed between the other end of the vertical slide 47 and the vertical sleeve 39.

[0039] Furthermore, a limit frame 50 is fixed on the side wall of the vertical sleeve 39, a positioning block 42 is slidably installed in the limit frame 50, a push spring 45 is fixed between the positioning block 42 and the limit frame 50, a fixed column 41 is vertically fixed on the sliding frame II40, two V-grooves 46 are provided on the fixed column 41 for the positioning block 42 to be clamped and adapted, an extension plate 44 is fixed on the side wall of the vertical sleeve 39, and a connecting spring 43 is fixed between the extension plate 44 and the sliding frame II40.

[0040] After the pulley hub 13 is clamped and fixed, the push fixing column 41 slides toward one side of the pulley hub 13, and when the positioning block 42 is plugged into the V-groove 46 close to the pulley hub 13, the position of the grinding head 38 is adjusted, so that under the elastic push action of the vertical spring 48, the grinding head 38 abuts against the surface of the pulley hub 13, ensuring that the grinding head 38 has sufficient clamping force on the pulley hub 13, thereby ensuring that the pulley hub 13 is fully polished.

[0041] After the surface of the pulley hub 13 is polished, the fixing column 41 is pulled in the opposite direction so that the positioning block 42 is plugged into the V-groove 46 away from the pulley hub 13. At this time, the polishing head 38 is reset, which facilitates the removal of the polished pulley hub 13.

[0042] In addition, the reciprocating drive assembly of the device includes a driving bevel gear 3 fixedly sleeved on the driving shaft 19, a driven bevel gear 5 is meshedly connected to the driving bevel gear 3, an incomplete bevel gear 6 is coaxially fixed to the driven bevel gear 5, two driving bevel gears 7 alternately meshed with the incomplete bevel gear 6 are rotatably mounted on the transmission box 2, a main gear 17 is coaxially fixed to the driving bevel gear 7, a sub gear 16 is meshedly connected to the main gear 17, and a driving screw 15 threadedly connected to the threaded sleeve 14 is coaxially fixed to the sub gear 16. A rotating plate 11 is rotatably mounted on the carrier 1, and strip holes 12 are provided at both ends of the rotating plate 11, and a driving column 37 fixed to the sliding frame II40 is slidably mounted on the strip hole 12.

[0043] Through the above arrangement, the motor I4 drives the driving bevel gear 3 to rotate, and the driving bevel gear 3 drives the driven bevel gear 5 to rotate, and the driven bevel gear 5 drives the incomplete bevel gear 6 coaxially fixed therewith to rotate, and the incomplete bevel gear 6 alternately meshes with the two transmission bevel gears 7, thereby realizing the main gear 17 to rotate alternately clockwise and counterclockwise, the main gear 17 drives the sub-gear 16 to rotate, and the sub-gear 16 drives the transmission screw 15 to rotate alternately clockwise and counterclockwise, at this time, the threaded sleeve 14 drives the sliding frame II40 to reciprocate laterally, that is, the grinding head 38 is realized to grind different axial positions of the pulley hub 13, and combined with the rotation of the pulley hub 13, sufficient grinding of the pulley hub 13 is guaranteed.

[0044] During the sliding process of the sliding frame II40, the transmission column 37 connected to the sliding frame II40 slides in the strip hole 12, so that the rotating plate 11 rotates alternately clockwise and counterclockwise. At this time, the rotating plate 11 drives another transmission column 37 to slide relative to another strip hole 12, thereby realizing the sliding of another sliding frame II40, and the sliding directions of the two sliding frames II40 are opposite, that is, the two grinding heads 38 move toward or away from each other, which greatly improves the grinding efficiency of the pulley hub 13.

[0045] In summary, the present invention can drive the two sliding frames II40 through the reciprocating drive assembly, so that the sliding frame II40 drives the grinding assembly to move toward or away from each other, and the grinding head 38 reciprocates along the axial direction of the pulley hub 13, while the pulley hub 13 rotates, which greatly improves the surface grinding treatment efficiency and sufficiency of the pulley hub 13. In the process of extending the extension cylinder 18 of the present invention to the inside of the pulley hub 13, the clamping block 23 clamps the end of the pulley hub 13, and the push assembly can simultaneously drive the wedge block I25 and the wedge block II26 to approach each other and clamp the pulley hub 13 radially, effectively ensuring the rotation stability of the pulley hub 13 during the grinding process, while achieving efficient clamping operation efficiency.
