Description

[Technical Field]

[0001] This utility model relates to the field of processing and production equipment technology, and in particular to an adjustment mechanism for adjusting the size of the R-shaped edge in the deep processing of the peripheral edge radius of a sheet metal. [Background Technology]

[0002] In existing technologies, most of the slabs are made of sintered stone, stone, or glass. For deep processing of the peripheral edge radius of the slabs, the peripheral edge radius is generally ground and polished using an inner radius-forming wheel to achieve the desired radius reduction.

[0003] In use, the sheet material to be processed is first fixed in the designated position. Then, the grinding forming wheel grinds the edges around the fixed sheet material. Following this, the material undergoes rough grinding, semi-fine grinding, and precision grinding processes to achieve the predetermined radius requirement.

[0004] During this grinding process, due to the limitation of the radius specification of the grinding forming wheel used, the edge radius of the processed plate cannot be made to any value. [Utility Model Content]

[0005] In view of this, the technical problem to be solved by this utility model is to provide an adjustment mechanism that can grind different R values ​​of R rounded corners to adjust the size of the R rounded corner.

[0006] To address the aforementioned technical problems, the present invention provides an adjustment mechanism for adjusting the size of the R-shaped edge, comprising a mechanism support directly placed on the bottom surface, a sheet metal workpiece to be processed, and the mechanism support including a swing frame bearing plate arranged longitudinally on both sides, and a bearing support frame installed on the top of the swing frame bearing plate.

[0007] A crank mechanism is installed below the support frame, and a swing mechanism is installed at the lower end of the swing frame support plate. A connecting rod mechanism for connection and driving is provided at the intersection of the upper end of the swing mechanism and the lower end of the crank mechanism.

[0008] The crank mechanism device includes two crank mechanisms, a power source device disposed between the two crank mechanisms, and crank shafts disposed at both ends of the power source device and respectively connected to the crank mechanisms.

[0009] The swing mechanism device includes a swing mechanism disposed inside the two swing frame support plates, a swing frame installed between the two swing mechanisms, and a plurality of grinding wheel devices installed on the swing mechanism.

[0010] The linkage mechanism includes two linkage mechanisms respectively located at the intersection of the crank mechanism and the swing mechanism;

[0011] A swing adjustment distance mechanism for adjusting the vertical movement distance of the swing mechanism is provided on the outer wall of the support frame.

[0012] In use, the power source device starts the crankshaft to rotate, which drives the crank mechanism located at both ends of the crankshaft to rotate. The crank mechanism drives the connecting rod mechanism to swing, which in turn drives the swing mechanism to swing. The swing mechanism drives the swing frame located on the swing mechanism to swing, and the swing frame drives the grinding wheel device to swing back and forth. When swinging, the grinding wheel device contacts one right-angled edge and two edge surfaces of the workpiece being processed, thus realizing the grinding action. During processing, the right-angled edge of the workpiece to be processed is placed at the inherent center point of the swing mechanism, and the grinding wheel device swings back and forth around the workpiece. If the center point of the swing mechanism is moved, the grinding wheel device can grind the rounded corners of the workpiece with different R values.

[0013] Further defined, the swing adjustment distance mechanism includes a vertical adjustment structure directly mounted on the swing bearing plate, and a front-back adjustment structure mounted on the vertical adjustment structure;

[0014] The up-down adjustment structure includes a vertical mounting plate directly mounted on the upper end of the swing bearing plate, a longitudinal adjustment motor mounted on the vertical mounting plate, an up-down adjustment bearing box module connected to the longitudinal adjustment motor mounted on the back of the vertical mounting plate, an up-down adjustment lead screw connected to the up-down adjustment bearing box module, a longitudinal guide rail bracket mounted around the up-down adjustment lead screw, a longitudinal guide rail mounting frame mounted on both sides of the upper end of the longitudinal guide rail bracket, and a longitudinal guide rail mounted inside the longitudinal guide rail mounting frame.

[0015] The front and rear adjustment structure includes front and rear adjustment guide rails directly mounted on both ends of the longitudinal guide rail mounting bracket, a front and rear adjustment plate that moves left and right along the front and rear adjustment guide rails and is mounted between the two front and rear adjustment guide rails, and a front and rear adjustment screw rod mounted on one side of the front and rear adjustment plate at the center position.

[0016] The beneficial technical effects of this utility model are as follows: swing adjustment distance mechanisms are respectively provided on the outer wall of the bearing support frame; the swing adjustment distance mechanism includes an up-and-down adjustment structure directly installed on the swing bearing plate, and a front-and-back adjustment structure installed on the up-and-down adjustment structure.

[0017] In this mechanism, the vertical movement distance of the swing mechanism is controlled by the vertical adjustment structure, while the forward and backward movement distance of the swing mechanism is controlled by the forward and backward adjustment structure.

[0018] In use, the crank mechanism drives the swing mechanism through the connecting rod mechanism to complete the swing action. Thus, the working surface of the grinding wheel device swings with the workpiece as the swing center point. If the swing adjustment distance mechanism is used to adjust the up, down, left, and right movement distance of the grinding wheel device, the position of the swing center point can be moved, thereby obtaining R rounded corners with different R values.

[0019] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and embodiments. [Attached Image Description]
