DETAILED DESCRIPTION

[0020] The present invention is described in detail below with reference to the accompanying drawings and embodiments: Figures 1 to 11 As shown, the side roller posture adjustment system for a wheel rolling mill of the present invention comprises a side roller 1 arranged vertically, a vertical adjustment mechanism 2 arranged at the left end of the side roller 1, the vertical adjustment mechanism 2 is connected to the side roller 1 in an up-and-down sliding manner, and the side roller 1 moves up and down along the right end surface of the vertical adjustment mechanism 2 to a set position by driving the vertical adjustment mechanism 2; the left end of the vertical adjustment mechanism 2 is connected to a horizontal adjustment mechanism 3, and the horizontal adjustment mechanism 3 is used to drive the vertical adjustment mechanism 2 to move left and right, and at the same time drive the side roller 1 connected to the vertical adjustment mechanism 2 to move left and right to a set position; In the present invention, the vertical adjustment mechanism 2 includes a fixed portion 4 connected to the left end horizontal adjustment mechanism 3 and a movable portion 5 connected to the right end edge roller 1; In order to realize the up and down movement of the edge roller 1: The fixed part 4 includes a vertically arranged support block 6, a protruding sliding track 7 is arranged on the right surface of the support block 6, a vertically arranged accommodating long groove 8 with a right end opening is arranged in the inner cavity of the support block 6, and a quick-release structure 9 is arranged inside the accommodating long groove 8; during operation, the quick-release structure 9 is connected to the moving part 5, and drives the moving part 5 to move up and down along the sliding track 7 through an external force; The moving part 5 includes a lifting ear 10 located in the inner cavity of the accommodating long slot 8 and connected to the quick-release structure 9 at the left end. The right end of the lifting ear 10 extends to the right end opening of the accommodating long slot 8 and is fixedly connected to the driving block 12. A slide groove 13 is provided at the left end surface of the driving block 12 corresponding to the position of the sliding track 7. The driving block 12 and the supporting block 6 cooperate with the slide groove 13 through the sliding track 7 and are slidably connected up and down. During operation, the quick-release structure 9 drives the lifting eye 10 to make the driving block 12 fixed on the right side of the lifting eye 10 move up and down through the cooperation of the sliding track 7 and the slide slot 13, so as to realize the relative sliding of the supporting block 6 in the fixed part 4 and the driving block 12 in the movable part 5, that is, the quick-release structure 9 drives the edge roller 1 connected to the movable part 5 to move up and down; In this embodiment, the quick-release structure 9 includes a lead screw 11 vertically arranged in the inner cavity of the accommodating long groove 8. The upper and lower ends of the lead screw 11 are respectively connected to the support block 6 through bearings. A lifting ear 10 is passed through the middle of the lead screw 11 and is connected through threads. The lead screw 11 and the lifting ear 10 can form self-locking in a state without relative rotation. In a state of relative rotation, the lead screw 11 and the lifting ear 10 can form a relative position change of the lead screw 11 and the lifting ear 10 through threads.

[0021] During operation, the lead screw 11 is driven to rotate, and the lifting lug 10 threadedly connected to the lead screw 11 moves upward or downward. At the same time, the driving block 12 fixed to the right end of the lifting lug 10 slides with the sliding track 7 and the slide groove 13 to achieve relative sliding between the support block 6 and the driving block 12. The up and down movement of the support block 6 and the driving block 12 can adjust the up and down position of the side roller 1 connected to the right side of the driving block 12. To facilitate the adjustment of the lead screw 11: The accommodating long groove 8 is T-shaped, including an upper transverse groove and a lower longitudinal groove, a partition 14 is arranged at the boundary between the transverse groove and the longitudinal groove, the partition 14 is fixed to the inner cavity at the bottom of the transverse groove, the upper light rod portion of the lead screw 11 is penetrated by the partition 14 and is rotatably connected with the partition 14, the lower light rod portion of the lead screw 11 is inserted into the bottom of the longitudinal groove of the inner cavity of the support block 6 and is rotatably connected with the support block 6, and a hexagonal adjustment nut 15 is concentrically fixedly arranged on the upper part of the lead screw 11; during the working process, the rotation drive of the lead screw 11 is realized by rotating the hexagonal adjustment nut 15; Since the right end of the moving part 5 is fixedly connected to the edge roller 1, and the edge roller 1 has a large mass, the downward gravity exerted on the edge roller 1 is completely transmitted to the threaded fitting point between the middle part of the lead screw 11 and the lifting ear 10 through the lifting ear 10. By rotating the lead screw 11, the edge roller 1 moves slowly upward to the set position. The threaded fitting point between the middle part of the lead screw 11 and the lifting ear 10 is easily deformed by force, making the lead screw 11 difficult to drive, which increases the difficulty of adjustment. In order to overcome this problem, in this embodiment, the quick-release structure 9 further includes a quick-connection portion 16 disposed above the lifting ear 10 and also threadedly connected to the lead screw 11. The quick-connection portion 16 is used to realize that during the assembly or adjustment of the side roller 1, the gravity of the side roller 1 can be distributed to other threads of the lead screw 11 through the quick-connection portion 16, so that the force at the threaded matching point between the middle part of the lead screw 11 and the lifting ear 10 can be distributed, thereby reducing the difficulty of adjustment; In the present invention, the quick-connect portion 16 includes a top block 17 disposed above the lifting ear 10 and threadedly connected to the lead screw 11, and a first gear 18 and a second gear 19 meshing with each other and having the same structure are symmetrically disposed at the front and rear ends of the right side of the lower end of the top block 17, and the first gear 18 and the second gear 19 are connected to the lower end of the top block 17 through a first gear shaft and a second gear shaft, respectively, and the left ends of the first gear shaft and the second gear shaft are respectively fixedly connected to the top block 17, and the right ends are respectively penetrated by the first gear 18 and the second gear 19 meshing with each other and are respectively rotatably connected to the first gear 18 and the second gear 19; In order to achieve better transmission effect through meshing between teeth: In this embodiment, the moving part 5 further includes a first rack 20 and a second rack 21 fixed to the left end surface of the driving block 12 and arranged corresponding to the outer sides of the first gear 18 and the second gear 19 respectively; During the working process, the first gear 18 and the second gear 19 meshing with each other are also meshed with the first rack 20 and the second rack 21 respectively; during assembly, the first gear 18 and the second gear 19 meshing with each other are moved to the middle position of the first rack 20 and the second rack 21 by rotating the gears, and the meshing with the first rack 20 and the second rack 21 is maintained, so that the assembly connection between the moving part 5 and the fixed part 4 can be completed; After the assembly is completed, the first gear 18 and the second gear 19 will no longer move relative to the first rack 20 and the second rack 21, respectively, to form a self-locking state; the downward gravity exerted on the edge roller 1 is transmitted to the thread of the lead screw 11 at the top block 17 through the first gear 18 and the second gear 19, so as to realize force sharing; In the present invention, a first movable through groove 22 and a second movable through groove 23 with the same direction are respectively opened at the positions of the first gear shaft and the second gear shaft corresponding to the first gear 18 and the second gear 19, and the first gear shaft and the second gear shaft respectively pass through the first movable through groove 22 and the second movable through groove 23 to pass through the first gear 18 and the second gear 19, and the first movable through groove 22 and the second movable through groove 23 are respectively opened along the radial direction of the first gear 18 and the second gear 19 and pass through the axis, and the first gear shaft and the second gear shaft are respectively slidably connected with the first gear 18 and the second gear 19 through the first movable through groove 22 and the second movable through groove 23; By driving the first gear 18 and the second gear 19 to move along the first moving through groove 22 and the second moving through groove 23, the first gear shaft and the second gear shaft can be eccentrically inserted into the first gear 18 and the second gear 19 respectively, and the first gear 18 and the second gear 19 are respectively meshed with the first rack 20 and the second rack 21 and squeezed against each other so that they cannot rotate, thereby achieving self-locking; During the assembly process, the lifting device is used to lift the edge roller 1 until the slide groove 13 on the moving part 5 at the left end of the edge roller 1 is in the corresponding position of the sliding track 7 of the fixed part 4, and moves upward along the sliding track 7, and the first gear 18 and the second gear 19 are adjusted so that the first moving groove 22 and the second moving groove 23 are respectively set vertically. At this time, the first gear 18 and the second gear 19 are not in contact with the first rack 20 and the second rack 21. Under the action of gravity, the first gear 18 and the second gear 19 meshing with each other will move downward along the first moving groove 22 and the second moving groove 23, and no relative rotation will occur; at this time, the first gear shaft and the second gear shaft are respectively located at the top of the first moving groove 22 and the second moving groove 23 on the first gear 18 and the second gear 19 meshing with each other, and the first gear shaft and the second gear shaft are both in an eccentric position, that is, the first gear 18 and the second gear 19 squeeze each other and cannot rotate; as the moving part 5 continues to move upward and squeeze the lower ends of the first gear 18 and the second gear 19, the first gear 18 and the first gear 19 are pressed against each other. The two gears 19 move upward without relative rotation. During this process, the first moving groove 22 and the second moving groove 23 on the first gear 18 and the second gear 19 move upward as a whole. When the first gear shaft and the second gear shaft are located in the middle of the first moving groove 22 and the second moving groove 23, they reach the axial position of the first gear 18 and the second gear 19. At this time, the first gear 18 and the second gear 19 meshing with each other start to rotate synchronously, and the first rack 20 and the second rack 21 meshing with the first gear 18 and the second gear 19, respectively, move upward relative to the first gear 18 and the second gear 19; In order to squeeze the first gear 18 and the second gear 19 during the upward movement of the moving part 5, when the first gear shaft and the second gear shaft move to the center of the first gear 18 and the second gear 19, the first gear 18 and the second gear 19 can automatically change from the upward movement to the meshing rotation along the first rack 20 and the second rack 21 respectively: In this embodiment, the left end surfaces of the first gear 18 and the second gear 19 are respectively coaxially provided with circular bosses 24, and a limiting block 25 is provided on the upper side of the circular boss 24. The left end of the limiting block 25 is fixed with the top block 17, so that when the lower end of the limiting block 25 is pressed against the circular boss 24, the first gear shaft and the second gear shaft are just concentrically penetrated by the first gear 18 and the second gear 19; that is, when the first gear 18 and the second gear 19 cannot move upward, the first rack 20 and the second rack 21 continue to be driven, and under the drive of the first rack 20 and the second rack 21, the first gear 18 and the second gear 19 are automatically converted from upward movement to rotation, that is, the driving block 12 fixed at the right end of the first rack 20 and the second rack 21 moves upward to achieve connection with the quick-connection part 16; In the existing assembly process, due to the large gravity of the edge roller 1 itself, it is relatively complicated and cumbersome to drive the edge roller 1 through the lifting equipment to adjust the position of the lifting lug 10 so that the lead screw 11 is correspondingly inserted to form a threaded fit; through the above structure in this embodiment, when the moving part 5 and the fixed part 4 are connected, the quick connection part 16 in the quick release structure 9 can quickly form a self-locking position, in order to reduce the difficulty of the subsequent lead screw 11 to insert the lifting lug 10, and at the same time, the gravity of the edge roller 1 is distributed to different threads of the lead screw 11; In this embodiment, the first gear 18 and the second gear 19 are respectively meshed with the first rack 20 and the second rack 21 and rise to a sufficient distance from the ends of the first rack 20 and the second rack 21, and the driving of the edge roller 1 can be stopped so that the edge roller 1 is only affected by gravity to achieve rapid positioning; under the action of gravity, the edge roller 1 drives the first gear 18 and the second gear 19 to rotate until the first movable through groove 22 and the second movable through groove 23 are first vertically arranged, and since the first gear shaft and the second gear shaft are respectively fixed to the top block 17, that is, the position remains unchanged, under the action of gravity, the first gear 18 and the second gear 19 and the first rack 20 and the second rack gear 21 move downward synchronously until the upper end surfaces of the first moving through groove 22 and the second moving through groove 23 contact the upper end surfaces of the first gear shaft and the second gear shaft, so that the first gear shaft and the second gear shaft are eccentrically penetrated with the first gear 18 and the second gear 19 respectively. Under the trend of the first rack gear 20 and the second rack gear 21 moving downward, the first gear 18 and the second gear 19 continue to drive the first gear 18 and the second gear 19 so that the first gear 18 and the second gear 19 meshing with each other are squeezed against each other to form a quick self-locking position; and then the lead screw 11 is driven to rotate so that the lead screw 11 can smoothly penetrate the lifting ear 10 to form a threaded connection.

[0022] In order to distribute the gravity of the edge roller 1 at different threads of the lead screw 11, in this embodiment, multiple groups of quick-connect parts 16 of the same structure can be provided along the lead screw 11; During the assembly process, when the edge roller 1 drives the first gear 18 and the second gear 19 to rotate until the first movable through groove 22 and the second movable through groove 23 are vertically set for the first time, the edge roller 1 needs to move downward a certain distance under the action of gravity. In order to shorten the distance that the edge roller 1 moves downward and make the first gear 18 and the second gear 19 form eccentric self-locking faster, in the present embodiment, in multiple groups of quick-connect parts 16 with the same structure, the directions of the first movable through groove 22 and the second movable through groove 23 in each pair of quick-connect parts 16 are different.

[0023] In this embodiment, the horizontal adjustment mechanism 3 can be a pull rod cylinder, and the movable end of the pull rod cylinder fixes the vertical adjustment mechanism 2.
