Description

Technical Field

[0001] The utility model belongs to the technical field of rim processing, in particular to an internal support type rim rolling machine. Background Art

[0002] The rim, commonly known as the wheel rim, is the part of the wheel that mounts and supports the tire. Together with the spokes, it forms the wheel. There are two common types of rims: deep groove rims and flat bottom rims. There are also split rims, semi-deep groove rims, deep groove wide rims, flat bottom wide rims, and full bevel bottom rims. The rim and spokes can be integral, permanently connected, or detachable.

[0003] During the implementation of the present invention, the inventors discovered that the technology has at least the following problems: When machining the rim, the original rim (the annular portion on the outside of the rim, rather than the entire rim) needs to be fixed to the rolling mechanism so that the rolling mechanism drives the original rim to rotate and performs corresponding mechanical processing during the rotation. Current rim rolling mechanisms are generally not easy to adjust, that is, they can only be used to fix and roll rims of a specific diameter, resulting in a small range of applications (for example, the patent application number CN201010144990.8 - the rim internal support rolling machine, the outer mold 47 and the rotating mechanism 20 used for rim molding cannot cooperate with each other or be used by other means to position rims of different sizes (diameters)).

[0004] For this reason, we propose a kind of inner support type wheel rim rolling machine to solve the above-mentioned problem. Utility Model Content

[0005] The main purpose of the utility model is to provide an internal support type rim rolling machine, on which the position of the movable bracket for positioning the rim original can be adjusted at will, so that the rim rolling machine is suitable for rolling rims with more different inner diameters, which can effectively solve the problems in the background technology.

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

[0007] An internally supported wheel rim rolling machine comprises a base and a rolling assembly located on the base, wherein a support is welded to the base, and a motor is horizontally mounted on one side wall of the support, wherein the motor is powered by external power facilities, and the output shaft of the motor is coaxially connected to a transmission shaft, wherein a baffle is welded to one side of an outer wall of the transmission shaft, and a movable groove is formed on the other side of the outer wall, and a ferrule splined to the transmission shaft is provided between the baffle and the movable groove, the ferrule and the baffle being fitted so that one side of the ferrule is limited by the action of the baffle, wherein the position where the transmission shaft and the ferrule are splined is located on the side of the outer wall of the transmission shaft facing away from the movable groove, so as not to conflict with the position of the movable groove;

[0008] Three outer rods are welded to the outer wall of the ring and distributed in a circular array along its axis. Cylinders are fixed on the three outer rods, and connecting rods are connected to the three cylinders. Telescopic blocks are welded on the three connecting rods. The rolling ring assembly includes movable brackets welded on the three telescopic blocks, wherein a receiving groove is formed on the outer side of each movable bracket, and a plurality of rolling grooves are formed in each receiving groove. A fixed cylinder is fixedly welded in each rolling groove, and a circle of rubber pads is fixedly bonded to the outer side of the fixed cylinder. The rubber pads are used to contact the inner wall of the rim to play a buffering role, so that there is sufficient friction between the fixed cylinder and the rim, so that the rotation of the movable bracket can drive the rotation of the rim. In addition, the base is L-shaped when viewed from the side, which can ensure the stability of the structure thereon and enable the movable bracket and the rim and other structures thereon to be normally installed and rolled.

[0009] As a preferred embodiment, the motor and the transmission shaft are respectively located on both sides of the support, and the transmission shaft is rotatably connected to the support; so that the transmission shaft can run stably under the drive of the motor, and the transmission shaft is arranged horizontally.

[0010] As a preferred embodiment, internal grooves are formed inside the three outer rods, and the three cylinders are respectively installed on the inner walls of the three internal grooves, so that the structures of the three cylinders remain fixed.

[0011] As a preferred embodiment, side grooves are formed on the sides of the three outer rods facing away from the ring, the three connecting rods are respectively located in the three side grooves, and the three telescopic blocks slide into the three side grooves respectively and fit with the inner walls of the side grooves; the telescopic block is limited by the fitting action of the inner walls of the side grooves, so that the telescopic block and the movable bracket can only move in one direction, which is conducive to stabilizing the telescopic block and the movable bracket.

[0012] As a preferred embodiment, a spring is fixedly connected to the inner wall of the movable groove, and an elastic seat is connected to the spring. The side of the elastic seat facing away from the spring extends out from the movable groove and abuts against the other side of the ring; thereby limiting the other side of the ring, so that the ring and structures such as the movable bracket thereon remain stable. At the same time, the elastic seat fits against the inner wall of the movable groove, so that the elastic seat will not shake in the movable groove.

[0013] In summary, the technical effects and advantages of the utility model are:

[0014] This internal support type rim rolling machine drives three sets of cylinders to operate, so that the fixed cylinders on the three sets of movable brackets contact the inner wall of the rim, so that the subsequent rims can be rolled along with the fixed cylinders on the three sets of movable brackets under the drive of the motor, thereby meeting the required processing requirements. Since the position of the movable brackets can be adjusted at will, the rim rolling machine is suitable for rolling rims with more different inner diameters.

[0015] When the ferrule and the structure thereon of the internally supported wheel rim rolling machine become unsuitable for operation or are damaged, the elastic seat can be squeezed to compress the spring and shrink into the movable groove, and then the ferrule can be slid in the direction away from the baffle, so that the ferrule and all the structures thereon (including the three movable brackets) can be removed from the transmission shaft, thereby replacing the movable brackets, and then the movable brackets of new specifications can be installed on the transmission shaft, which facilitates subsequent maintenance work.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Reference Figure 1-Figure 4 , an internal support type wheel rim rolling machine, comprising a base 1 and a rolling assembly located on the base 1. The wheel rim (original) referred to in this application does not refer to the entire wheel rim processed in the factory, but the outer ring of the wheel rim (i.e. the outermost part of the wheel rim, which is annular in design). As for the inner part of the wheel rim, it is not within the scope of the present technical solution. A support 2 is welded on the base 1, and a motor 3 is horizontally installed on one side wall of the support 2, wherein the motor 3 is powered by external power facilities, and the output shaft of the motor 3 is coaxially connected to the transmission shaft 4, the motor 3 and the transmission shaft 4 are respectively located on both sides of the support 2, and the transmission shaft 4 is rotatably connected to the support 2, so that the transmission shaft 4 can run stably under the drive of the motor 3, and the transmission shaft 4 is arranged horizontally;

[0023] Refer to the attached Figure 1 and attached Figure 4A baffle 5 is welded to one side of the outer wall of the transmission shaft 4, and a movable groove 17 is formed on the other side of the outer wall. A ferrule 6 spline-connected to the transmission shaft 4 is provided between the baffle 5 and the movable groove 17. The ferrule 6 fits with the baffle 5 so that one side of the ferrule 6 is limited by the action of the baffle 5. The position where the transmission shaft 4 and the ferrule 6 are spline-fitted is located on the side of the outer wall of the transmission shaft 4 that is away from the movable groove 17, so as not to conflict with the position of the movable groove 17.

[0024] Three outer rods 7 are welded to the outer wall of the ferrule 6 and are distributed in a circular array along its axis. Cylinders 9 are fixed to the three outer rods 7 respectively. Internal grooves 8 are formed inside the three outer rods 7. The three cylinders 9 are respectively installed on the inner walls of the three internal grooves 8, so that the structure of the three cylinders 9 remains fixed, and connecting rods 11 are respectively connected to the three cylinders 9. Telescopic blocks 12 are respectively welded to the three connecting rods 11. The rolling ring assembly includes movable brackets 13 respectively welded to the three telescopic blocks 12. Side grooves 10 are formed on the side of the three outer rods 7 facing away from the ferrule 6. The three connecting rods 11 are respectively located in the three side grooves 10, and the three telescopic blocks 12 slide into the three side grooves 10 respectively and fit with the inner walls of the side grooves 10. The telescopic block 12 is limited by the fitting action of the inner walls of the side grooves 10, so that the telescopic block 12 and the movable bracket 13 can only move in one direction, which is conducive to stabilizing the telescopic block 12 and the movable bracket 13.

[0025] Refer to the attached Figure 1 and attached Figure 3 A receiving groove 14 is formed on the outside of each movable bracket 13, and a plurality of rolling grooves 15 are formed in each receiving groove 14. A fixing cylinder 16 is fixedly welded in each rolling groove 15, and a circle of rubber pad is fixedly bonded to the outside of the fixing cylinder 16. The rubber pad is used to contact the inner wall of the rim to play a buffering role, so that there is sufficient friction between the fixing cylinder 16 and the rim, so that the rotation of the movable bracket 13 can drive the rotation of the rim. In addition, the base 1 is L-shaped when viewed from the side, which can ensure the stability of the structure thereon and enable the movable bracket 13 and the rim and other structures thereon to be normally installed and rolled.

[0026] Refer to the attached Figure 1 and attached Figure 4 In addition, a spring 18 is fixedly connected to the inner wall of the movable groove 17, and an elastic seat 19 is connected to the spring 18. The side of the elastic seat 19 facing away from the spring 18 extends out from the movable groove 17 and abuts against the other side of the ring 6; thereby limiting the other side of the ring 6, so that the ring 6 and the movable bracket 13 thereon and other structures remain stable. At the same time, the elastic seat 19 fits with the inner wall of the movable groove 17, so that the elastic seat 19 will not shake in the movable groove 17.

[0027] The inner-supported wheel rim rolling machine: before rolling the wheel rim, the three movable brackets 13 are first retracted inwardly under the action of the three cylinders 9, so that the wheel rim is horizontally moved from the side of the base 1 facing away from the motor 3 to the outside of the three movable brackets 13, so that the wheel rim corresponds to the position of the three movable brackets 13. Then, the three cylinders 9 are operated to drive the three connecting rods 11 to extend, so that the three telescopic blocks 12 move in the direction away from the ring 6, and finally the rubber pads on the fixed cylinders 16 inside the three movable brackets 13 are in contact with the inner wall of the wheel rim, and the wheel rim is fixed with the help of the fixed cylinders 16 (and the rubber pads thereon) on the three movable brackets 13.

[0028] After that, the driving motor 3 is powered on and the transmission shaft 4 is rotated, so that the ferrule 6 and all the structures thereon (including the three movable brackets 13) rotate and drive the original wheel rim to perform a rolling motion, and the corresponding machining process can be performed on the outer side of the original wheel rim.

[0029] When the ferrule 6 and the structure thereon are unsuitable for work or damaged, the elastic seat 19 can be squeezed to squeeze the spring 18 and shrink into the movable groove 17, and then the ferrule 6 can be slid in the direction away from the baffle 5, and the ferrule 6 and all the structures thereon (including the three movable brackets 13) can be removed from the transmission shaft 4, thereby replacing the movable bracket 13, and then the new specification of the movable bracket 13 can be installed on the transmission shaft 4 (the inside of the new specification of the movable bracket 13 should also have structures such as the ferrule 6, cylinder 9, connecting rod 11 and telescopic block 12).

[0030] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
