Description

[Technical Field]

[0001] This utility model relates to the technical field of processing and production equipment, and in particular to a grinding rounded edge swing mechanism for processing the right-angled edges around the perimeter of a sheet metal. [Background Technology]

[0002] In existing technology, stone slabs are made of rock or stone materials, or glass slabs are made of glass materials; both stone slabs and glass slabs are collectively referred to as slabs. When processing the right-angled edges around the perimeter of the slab, the right angles are transformed into rounded corners or rounded edges of different radius (R). Generally, the radius of the right-angled edges around the perimeter of the slab is ground and polished using an inner radius forming wheel to achieve the purpose of radius processing.

[0003] In use, the sheet material to be processed is first clamped in the designated position of the equipment. The grinding wheel remains stationary, while the sheet material moves to the position of the grinding wheel under the action of the clamping device to complete the grinding. Then, the grinding wheel grinds the edges of the right-angled sides of the sheet material. Through rough grinding, semi-fine grinding or fine grinding, and final polishing, the radius requirement of the predetermined curvature is achieved.

[0004] During the aforementioned grinding process, if the grinding and polishing motion feed direction or the grinding direction is consistent with the feed direction of the workpiece, the hard points on the workpiece and the grinding wheel cause the brushed lines to remain, resulting in burrs and rough edges on the surface of the R-shaped edge of the workpiece. Consequently, the surface appearance of the R-shaped edge is not ideal. Furthermore, uneven wear and deformation of the R-shaped edge surface within the forming wheel also deforms the R-shaped edge surface processed on the workpiece, thus failing to meet the processing requirements. [Utility Model Content]

[0005] In view of this, the technical problem to be solved by this utility model is to provide a grinding R-circle edge swing mechanism that can solve the technical problems of burrs, rough edges and irregular shapes on the R-circle edge surface of the processed sheet metal workpiece.

[0006] To address the aforementioned technical problems, the present invention provides a grinding R-shaped edge swing mechanism, which includes a mechanism support directly placed on the bottom surface, a plate workpiece to be processed, and the mechanism support includes 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 under the support frame, a swing mechanism is installed at the lower end of the swing frame support plate, a connecting rod mechanism for connection and driving is installed at the intersection of the upper end of the swing mechanism and the lower end of the crank mechanism, and a swing adjustment distance mechanism is installed on the outer wall of the support frame.

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

[0009] The linkage mechanism includes two linkage mechanisms respectively located at the intersection of the crank mechanism and the swing mechanism;

[0010] 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 frame;

[0011] In use, the power source device starts the crank rotating shaft to rotate, which drives the crank mechanism set at both ends of the crank rotating shaft to rotate. The crank mechanism drives the connecting rod mechanism to swing, the connecting rod mechanism drives the swing mechanism to swing, the swing mechanism drives the swing frame set on the swing mechanism to swing, and the swing frame drives the grinding head wheel device to perform a back-and-forth swinging motion. When the grinding head wheel device swings, it contacts the right-angled edges of the workpiece plate around the perimeter to achieve grinding.

[0012] During processing, the right-angled edge of the sheet metal 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 sheet metal workpiece. If the center point of the swing mechanism is moved, the grinding wheel device can grind the R rounded corners of the sheet metal workpiece with different R values.

[0013] Further defined, the swing mechanism includes a long horizontal arm installed on the upper inner side of the swing frame support plate, a short horizontal arm installed on the lower inner side of the swing frame support plate, a long vertical arm installed on the front inner side of the swing frame support plate, and a short vertical arm installed on the rear inner side of the swing frame support plate; a lower swing pivot installed at the intersection of the lower end of the long vertical arm and the front end of the short horizontal arm; and an upper swing pivot installed at the intersection of the upper end of the long vertical arm and the front end of the long horizontal arm, which hinges the adjustable-length connecting rod, the long vertical arm, and the long horizontal arm together; the upper ends of the long vertical arm and the short vertical arm are respectively hinged to the two ends of the long horizontal arm; one end of the short horizontal arm is fixed to the top of the swing frame support plate, and the other end of the short horizontal arm is hinged to the lower end of the long vertical arm; the short horizontal arm with the long vertical arm installed swings along the end of the short horizontal arm fixed to the swing frame support plate as the center.

[0014] Further defined, the swing frame includes a swing box crossarm bracket directly mounted on the lower end of the short crossarms on both sides, multiple longitudinally arranged swing guide rails mounted on the swing box crossarm bracket, a guide rail slide plate that can move back and forth mounted on the multiple swing guide rails, and multiple grinding wheel devices mounted on the guide rail slide plate.

[0015] Further specifying, the grinding wheel device includes a grinding head motor directly fixedly mounted on the guide rail slide, and a grinding wheel mounted on the grinding head motor.

[0016] The beneficial technical effects of this utility model are as follows: because a swing mechanism is provided on the inner wall of the support frame, the swing mechanism includes a swing mechanism provided on the inner side of 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 frame.

[0017] The swing mechanism includes a long horizontal arm installed on the upper inner side of the swing frame support plate, a short horizontal arm installed on the lower inner side of the swing frame support plate, a long vertical arm installed on the front inner side of the swing frame support plate, and a short vertical arm installed on the rear inner side of the swing frame support plate; a lower swing pivot installed at the intersection of the lower end of the long vertical arm and the front end of the short horizontal arm, and an upper swing pivot installed at the intersection of the upper end of the long vertical arm and the front end of the long horizontal arm, which hinges the connecting rod, the long vertical arm, and the long horizontal arm together; the upper ends of the long vertical arm and the short vertical arm are respectively hinged to the two ends of the long horizontal arm; one end of the short horizontal arm is fixed to the top of the swing frame support plate, and the other end of the short horizontal arm is hinged to the lower end of the long vertical arm; the short horizontal arm with the long vertical arm is installed swings along the end of the short horizontal arm fixed to the swing frame support plate as the center.

[0018] In the above structure, multiple sets of parallelogram frames are formed by hinged connections of long horizontal arm, short horizontal arm, long vertical arm, and short vertical arm. By setting an upper swing pivot and a lower swing pivot on the same side of the swing frame support plate, the line connecting the center points of the two fixed pivots is located on one side of the swing support plate.

[0019] In operation, when the crank mechanism and connecting rod mechanism drive the long horizontal arm to rotate along the upper swing shaft, the short horizontal arm and the swing box horizontal arm will also rotate synchronously by the same angle, and the grinding wheel device will also change its angle synchronously. Simultaneously, the center lines of the upper and lower swing shafts intersect at a point formed by extending the line connecting the centers of the two shafts of the swing box horizontal arm. This intersection point does not change with the rotation of the swing box horizontal arm. The center of the R-shaped edge of the sheet metal workpiece is placed at this intersection point, and the working surface of the grinding wheel is also placed at this intersection point. The swing frame drives the grinding wheel to move around this intersection point, so the trajectory of the grinding wheel's working surface falls on the outer circle of the R-shaped edge of the sheet metal, thus completing the grinding and polishing of the outer R-shaped edge of the sheet metal. Changing the distance from this intersection point to the two sides of the sheet metal to be processed also changes the size of the R-shaped edge. This technology fundamentally solves the problem of consistent grinding direction between the workpiece and the grinding wheel in existing technologies, as well as technical defects such as uneven wear and deformation. This achieves the goal of solving technical problems such as burrs, rough edges, and irregular shapes on the R-shaped edge surface of the processed workpiece.

[0026] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0027] Please refer to Figures 1 to 5 As shown below, an embodiment of a grinding R-shaped edge swing mechanism is described, which includes a mechanism support directly placed on the bottom surface, a sheet metal workpiece 1 to be processed, a crank mechanism, a swing mechanism, a connecting rod mechanism, and a swing adjustment distance mechanism 5.

[0033] The swing mechanism includes a swing mechanism disposed inside the two swing frame support plates 201, a swing frame installed between the two swing mechanisms, and a plurality of grinding wheel devices installed on the swing mechanism.

[0034] The swing mechanism includes a long horizontal arm 601 installed on the upper inner side of the swing frame support plate 201, a short horizontal arm 602 installed on the lower inner side of the swing frame support plate 201, a long vertical arm 603 installed on the front inner side of the swing frame support plate 201, and a short vertical arm 604 installed on the rear inner side of the swing frame support plate 201; a lower swing pivot 605 installed at the intersection of the lower end of the long vertical arm 603 and the front end of the short horizontal arm 602; and a connecting rod 403 and a long horizontal arm 604 installed at the intersection of the upper end of the long vertical arm 603 and the front end of the long horizontal arm 601. The upper swing shaft 606 is hinged together with the vertical arm 601 and the long horizontal arm 602; the upper ends of the long vertical arm 601 and the short vertical arm 602 are respectively hinged to the two ends of the long horizontal arm 601; one end of the short horizontal arm 602 is fixed to the swing frame support plate 201, and the other end of the short horizontal arm 602 is hinged to the lower end of the long vertical arm 603; the short horizontal arm 602, which is equipped with the long vertical arm 603, swings around the end of the short horizontal arm 602 that is fixed to the swing frame support plate 201.

[0035] The swing frame includes a swing box crossarm support 607 directly mounted on the lower end of the short crossarms 602 on both sides, multiple longitudinally arranged swing guide rails 608 mounted on the swing box crossarm support 607, a guide rail slide plate 609 that can move back and forth mounted on the multiple swing guide rails 608, and multiple grinding head wheel devices mounted on the guide rail slide plate 609. The grinding head wheel device includes a grinding head motor 610 directly fixedly mounted on the guide rail slide plate 609, and grinding wheels 611 mounted on the grinding head motor 610.

[0036] During installation, the crank mechanism is mounted below the support frame 202, the swing mechanism is mounted at the lower end of the swing support plate 201, and the connecting rod mechanism is mounted at the intersection of the upper end of the swing mechanism and the lower end of the crank mechanism. This connecting rod mechanism is mainly used for connection and driving. The swing adjustment distance mechanism 5 is mounted on the outer wall of the support frame 202. This swing adjustment distance mechanism 5 is mainly used to adjust the vertical movement distance of the swing mechanism. The upper end of the connecting rod mechanism is connected to the eccentric hole on the crank rotating disk 306, while the lower end of the connecting rod mechanism is connected to the upper end of the long vertical arm 603 in the swing mechanism through the upper swing shaft 606.

[0037] In the aforementioned mechanism, the vertical movement distance of the swing mechanism 5 is controlled by a vertical adjustment structure, while the forward and backward movement distance of the swing mechanism 5 is controlled by a horizontal adjustment structure. In use, the crank mechanism drives the swing mechanism to complete the swinging motion via a connecting rod mechanism. The right-angled edge of the workpiece 1 is placed at the inherent center point of the swing mechanism, and the grinding wheel device swings back and forth around the workpiece 1. By adjusting the vertical, horizontal, and vertical movement distance of the grinding wheel device through the swing adjustment distance mechanism 5, the position of the swing center point can be moved, thereby obtaining R-rounded edges with different R values.

[0038] In use, the power source device starts the crank rotating shaft 301 to rotate. The crank rotating shaft 301 drives the crank mechanism set at both ends of the crank rotating shaft 301 to rotate. The crank mechanism drives the connecting rod mechanism to swing. The connecting rod mechanism drives the swing mechanism to swing. The swing mechanism drives the swing frame set on the swing mechanism to swing. The swing frame drives the grinding head wheel device to perform a back-and-forth swinging motion. When the grinding head wheel device swings, it contacts the right-angled edges of the plate workpiece 1 being processed, thereby realizing grinding.

[0039] During processing, the right-angled edge of the sheet metal 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 sheet metal workpiece 1. By moving the center point of the swing mechanism, the grinding wheel device can grind the R-rounded edges of the sheet metal workpiece 1 with different R values. In the aforementioned swing mechanism, multiple sets of connected parallelogram frames are formed by hinged connections of the long horizontal arm 601, short horizontal arm 602, long vertical arm 603, and short vertical arm 604. The upper swing shaft 606 and lower swing shaft 605 on the same side of the swing frame support plate 201 are positioned so that the line connecting the center points of the two fixed shafts is located on one side of the swing support plate 201. In use, when the crank mechanism and connecting rod mechanism drive the long horizontal arm 601 to rotate along the upper swing shaft 606 and upper swing shaft 605, the short horizontal arm 602 and the swing box horizontal arm 607 will also rotate synchronously by the same angle, and the grinding wheel device will also change its angle synchronously. Simultaneously, the center lines of the upper swing shaft 606 and the lower swing shaft 605 intersect at a point formed by extending the connecting line between the centers of the two shafts of the swing box cross arm 607. This intersection point remains unchanged as the swing box cross arm 607 rotates. The center of the R-shaped edge of the workpiece 1 being processed is placed at this intersection point, as is the working surface of the grinding wheel 611. The swing frame drives the grinding wheel 611 to move around this intersection point, so the trajectory of the grinding wheel's working surface falls on the outer circle of the R-shaped edge of the workpiece 1, thus completing the grinding and polishing of the outer R-shaped edge of the workpiece 1. Changing the distance from this intersection point to the two right-angled surfaces of the workpiece 1 being processed also changes the size of the R-shaped edge. This fundamentally solves the problem of consistent grinding direction between the workpiece and the grinding wheel in existing technologies, as well as technical defects such as uneven wear and deformation, thereby achieving the goal of solving technical problems such as burrs, rough edges, and irregular shapes on the surface of the R-shaped edge of the workpiece being processed.

[0040] The preferred embodiments of this utility model have been described above with reference to the accompanying drawings, but this does not limit the scope of the utility model. Any modifications, equivalent substitutions, and improvements made by those skilled in the art without departing from the scope and essence of this utility model should be within the scope of the utility model.
