Description

Technical Field

[0001] The utility model relates to the technical field of automobile flywheel processing, in particular to an automobile flywheel positioning device. Background Art

[0002] During the automotive flywheel manufacturing process, permanent markings must be applied to the workpiece surface to ensure accurate traceability. This requires placing the semi-finished or finished flywheels on a marking machine for marking. To facilitate inspection and calibration, the marking is typically placed in the same location on each batch of flywheels. However, due to the flywheel's heavy weight, workers struggle to precisely position the flywheels during handling. This results in deviations in the marking position on each flywheel, hindering both finding and viewing the markings and the uniform aesthetics of the finished flywheels. Utility Model Content

[0003] In view of the deficiencies in the prior art, the present invention proposes an automobile flywheel positioning device to solve the above problems.

The telescopic cylinder is installed on the top of the base and below the support platform, with its telescopic shaft end facing upward and mounted with the top plate. The tip of the top cone faces upward and is axially rotatably mounted on the top of the top plate. The top cone is located directly below the positioning hole.

[0008] A control mechanism is used to control the rotation of the top cone.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0028] like Figure 1-4 As shown, this embodiment provides an automobile flywheel positioning device, which includes a base 1, a positioning mechanism 2 and a control mechanism 3.

[0029] A support platform 12 is installed on the top of the base 1 through multiple support columns 11 at intervals, so that the support platform 12 has a certain height. The top of the support platform 12 is used to place the flywheel to be marked, and a positioning hole 121 is opened in the middle of the support platform 12.

[0030] The positioning mechanism 2 includes a telescopic cylinder 21, a top plate 22 and a top cone 23. The telescopic cylinder 21 can be a hydraulic cylinder or an electric cylinder. The telescopic cylinder 21 is installed on the top of the base 1 and is located below the support platform 12. The telescopic shaft end of the telescopic cylinder 21 faces upward and is installed with the top plate 22. The tip of the top cone 23 faces upward and is axially rotatably installed on the top of the top plate 22. Specifically, a bearing is installed between the bottom of the top cone 23 and the top of the top plate 22. The top cone 23 is located directly below the positioning hole 121. When the telescopic shaft of the telescopic cylinder 21 extends upward, the top tip of the top cone 23 can protrude upward from the positioning hole 121. When the flywheel is placed on the top of the support platform 12 and its hole is roughly within the range of the positioning hole 121, the tip of the top cone 23 can protrude into the middle hole of the flywheel, and as the top cone 23 rises, the middle hole of the flywheel is pushed and corrected by the side wall of the top cone 23, so that the middle hole of the flywheel is gradually aligned with the center of the top cone 23, thereby realizing the center correction positioning of each flywheel on the support platform 12.

[0031] Preferably, the surface of the top cone 23 is covered with a rubber layer, which is beneficial to increasing the friction between the surface of the top cone 23 and the hole in the flywheel, while preventing the two from being damaged by collision.

[0032] The control mechanism 3 is used to control the rotation of the top cone 23, and further control the flywheel to rotate to a specified position.

[0033] By utilizing the thrust when the top cone 23 rises and the flywheel's own gravity, the side wall of the top cone 23 can apply lateral thrust to the inner wall of the flywheel's center hole, and as the top cone 23 rises, the diameter of its side wall in the same plane as the flywheel will gradually approach the diameter of the flywheel's center hole, which is conducive to aligning the flywheel center with the center of the top cone 23, thereby achieving auxiliary positioning of the flywheel. After the top cone 23 completely positions the flywheel, the top cone 23 continues to rise, causing the flywheel to be pushed off the surface of the support platform 12 by the top cone 23. At this time, the flywheel position can be synchronously adjusted by rotating the top cone 23 through the control mechanism 3, and excessive wear on the bottom of the flywheel and the support platform 12 can be avoided.

[0034] Specifically, the control mechanism 3 includes a U-shaped seat 31, a rack 32 and a ring gear 33. The ring gear 33 is installed on the bottom periphery of the top cone 23. The U-shaped seat 31 is installed on one side of the top plate 22 with its notch facing the ring gear 33. The rack 32 is slidably installed on the inner side of the U-shaped seat 31 and engages with the ring gear 33. By sliding the rack 32, the ring gear 33 can be engaged to rotate, thereby driving the top cone 23 to rotate, which is convenient for control.

[0035] Furthermore, a movable gap 34 is left between an inner side of the U-shaped seat 31 and the rack 32, and a strip groove 321 is opened on the side of the rack 32 facing the movable gap 34, and a locking rod 322 is axially rotatably installed in the strip groove 321. One side of the locking rod 322 has an arc protrusion 323. Rotating the locking rod 322 can make the arc protrusion 323 retract into the strip groove 321 or press against the inner wall of the U-shaped seat 31, and when the arc protrusion 323 rotates to press against the inner wall of the U-shaped seat 31, it can increase the friction between it and the inner wall of the U-shaped seat 31, thereby limiting the movement of the rack 32 and achieving the effect of locking the movement of the rack 32.

[0036] Preferably, one end of the locking rod 322 passes through one end of the rack 32 and is installed with a turning handle 324. The rack 32 can be controlled to move by pushing the turning handle 324, and the locking rod 322 can be controlled to rotate by rotating the turning handle 324, which is convenient for operation.

[0037] In one embodiment, a plurality of movable balls 122 are evenly embedded on the top surface of the support platform 12. The movable balls 122 can be freely rotatably embedded on the top surface of the support platform 12. When the flywheel is placed on the top surface of the support platform 12, it can contact the movable balls 122 and rotate to realize its own movement. The flywheel can be moved more effortlessly, and the friction between the flywheel and the top surface of the support platform 12 is reduced, thereby improving the protection of the flywheel.

[0038] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some or all of the technical features therein. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the various embodiments of the present invention, and they should all be included in the scope of the claims and description of the present invention.
