Description

Technical Field

[0001] This utility model relates to the field of CNC grinding wheel technology, specifically a CNC grinding wheel angle adjustment mechanism. Background Technology

[0002] CNC grinding wheel refers to the grinding tool installed on a CNC grinding machine for grinding the surface of a workpiece. The grinding wheel is mainly composed of abrasive grains, bonding agent, and holes. The bonding agent tightly binds the abrasive grains to form a grinding tool with a specific shape and a certain strength. When the angle of the CNC grinding wheel is adjusted, the angle adjustment mechanism of the CNC grinding wheel is required.

[0003] The grinding wheel angle adjustment mechanism of the CNC grinding machine changes the angle by driving the rotating panel with a motor. The grinding wheel spindle box is installed on the rotating panel. When the grinding wheel spindle box rotates, it can drive the grinding wheel installed above to adjust the angle. However, the overall mechanism lacks corresponding auxiliary structures, which makes it not very flexible in the rotation adjustment.

[0004] Therefore, we propose a novel CNC grinding machine wheel angle adjustment mechanism to solve the above-mentioned technical problems. Utility Model Content

[0033] Example 1

[0034] This embodiment provides a technical solution: a CNC grinding machine grinding wheel angle adjustment mechanism, such as... Figures 1-5 As shown, it includes a grinding machine four-hole positioning plate 5, a rotating rolling seat, an angle adjustment mechanism, a telescopic contact mechanism, a positioning rotating mounting seat, and a grinding wheel spindle box body.

[0035] The four-hole positioning plate 5 of the grinding machine is installed on an external CNC grinding machine with screws, making it easy to install and remove. The rotating rolling seat is fixed to the upper end of the four-hole positioning plate 5. The rotating rolling seat can be correspondingly installed and connected through the four-hole positioning plate 5. The angle adjustment mechanism is installed and connected between the four-hole positioning plate 5 and the rotating rolling seat. The angle adjustment mechanism can be driven to adjust the angle inside the four-hole positioning plate 5 and the rotating rolling seat. The telescopic abutment mechanism is fixed to the inner side of the front end of the rotating rolling seat. The telescopic abutment mechanism can extend and abut on the rotating rolling seat for positioning. The positioning rotating mounting seat is fixed to the angle adjustment mechanism. The angle of the positioning rotating mounting seat can be changed by the rotation of the angle adjustment mechanism. The grinding wheel spindle box body is installed on the positioning rotating mounting seat with screws. When the angle of the positioning rotating mounting seat changes, the angle of the upper grinding wheel spindle box body can be changed, thus changing the angle for rotating grinding.

[0036] like Figures 1-4 As shown, the angle adjustment mechanism includes a first electric telescopic cylinder 4, which is mounted on the four-hole positioning plate 5 of the grinding machine by screws. The first electric telescopic cylinder 4 can be stably placed on the four-hole positioning plate 5 of the grinding machine for telescopic movement. A gear pulling plate 41 is fixedly connected to the telescopic rod end of the first electric telescopic cylinder 4. When the telescopic rod of the first electric telescopic cylinder 4 is telescopic, it can drive the gear pulling plate 41 to move back and forth. The upper end of the gear pulling plate 41 is engaged with a rotating roller gear 42. When the gear pulling plate 41 moves back and forth, it engages and drives the rotating roller gear 42 to rotate. Positioning rotating rods 43 are fixedly connected to both ends of the rotating roller gear 42. When the rotating roller gear 42 rotates, it can drive the positioning rotating rods 43 to rotate. The rotating roller gear 42 is rotatably mounted on the hollow seat shell 6 through the positioning rotating rods 43, so that the positioning rotating rods 43 can be positioned and rotated on the hollow seat shell 6. A positioning rotating mounting seat is fixedly connected to the outer end of the positioning rotating rod 43. When the positioning rotating rod 43 rotates, it can drive the positioning rotating mounting seat to rotate and change the angle.

[0037] The positioning rotating mounting base includes a concave rotating base 2. Positioning shaft blocks 21 are fixedly connected to the inner sides of both ends of the concave rotating base 2. The concave rotating base 2 can be fixedly connected to the positioning shaft blocks 21. The concave rotating base 2 is fixedly connected to the positioning rotating rod 43 through the positioning shaft blocks 21. Thus, the positioning rotating rod 43 can drive the positioning shaft blocks 21 to rotate during rotation, and the positioning shaft blocks 21 can drive the concave rotating base 2 to rotate. A grinding wheel spindle box body is installed at the upper end of the concave rotating base 2, and the concave rotating base 2 can drive the grinding wheel spindle box body installed at the upper end to rotate.

[0038] The concave rotating seat 2 is fitted onto the periphery of the hollow housing 6 through the bottom cavity, so that the concave rotating seat 2 can be positioned and rotated on the periphery of the hollow housing 6.

[0039] The rotating mounting seat includes a hollow housing 6. The lower end of the hollow housing 6 is fixed to a four-hole positioning plate 5 of the grinding machine. The hollow housing 6, via the four-hole positioning plate 5, can be screwed into a designated position on the grinding machine. Arc-shaped connecting plates 3 are fixed to both sides of the upper end of the hollow housing 6. These arc-shaped connecting plates 3 allow the rotating mounting seat to rotate at an angle. Rolling balls 31 are rotatably mounted on the inner side of the upper end of the arc-shaped connecting plates 3. The rolling balls 31 allow the arc-shaped connecting plates 3 to roll against the inner wall of the rotating mounting seat, thus enabling the rotating mounting seat to adjust its angle. The hollow housing 6 can be rolled and adjusted, making it more flexible during adjustment. A telescopic abutment mechanism is fixedly connected to the inner front end of the hollow housing 6. The telescopic abutment mechanism can telescopically abut against the hollow housing 6. Positioning bearings 61 are fixedly connected to the inner ends of the hollow housing 6. The hollow housing 6 can be positioned by the positioning bearings 61. An angle adjustment mechanism is rotatably installed on the inner side of the hollow housing 6 through the positioning bearings 61. The angle adjustment mechanism can be positioned and rotated in the positioning bearings 61 of the hollow housing 6. An inner cavity 62 is opened inside the hollow housing 6. The hollow housing 6 can be wrapped and positioned through the area of ​​the inner cavity 62.

[0040] In use, the four-hole positioning plate 5 of the grinding machine is installed on an external CNC grinding machine with screws, making it easy to install and remove. The rotating rolling seat can be installed and connected to the grinding machine through the four-hole positioning plate 5. The angle adjustment mechanism can be driven inside the grinding machine four-hole positioning plate 5 and the rotating rolling seat to adjust the angle. The positioning rotating mounting seat can change the angle through the rotation of the angle adjustment mechanism. The grinding wheel spindle box body is installed on the positioning rotating mounting seat with screws, so that when the angle of the positioning rotating mounting seat changes, the angle of the upper grinding wheel spindle box body can be changed, thus changing the angle for rotating grinding. The telescopic abutment mechanism is fixed to the inner side of the front end of the rotating rolling seat. The telescopic abutment mechanism can extend on the rotating rolling seat to abut against the positioning rotating mounting seat for positioning.

[0041] Example 2

[0042] This embodiment is a further optimization based on Embodiment 1. The parts that are the same as those described above will not be repeated here. Figures 1-4 As shown, to further better realize this utility model, the following configuration is specifically adopted: the grinding wheel spindle box body includes a grinding wheel spindle box body 1. The grinding wheel spindle box body 1 is mounted on the concave rotating base 2 by screws on the lower end screw mounting seat 13, so that the grinding wheel spindle box body 1 can be installed accordingly. A drive motor 12 is installed on the outer end screw of the grinding wheel spindle box body 1. The gear inside the grinding wheel spindle box body 1 can be driven to rotate through the output shaft of the drive motor 12. When the gear inside the grinding wheel spindle box body 1 rotates, it can drive the upper output shaft to rotate. A grinding wheel mounting plate 11 is fixedly connected to the upper output shaft of the grinding wheel spindle box body 1. When the output shaft of the grinding wheel spindle box body 1 rotates, it can drive the grinding wheel mounting plate 11 to rotate.

[0043] The telescopic abutment mechanism includes a hollow sleeve 7, which is fixedly connected to the inner sleeve hole at the front end of the hollow base shell 6. The hollow sleeve 7 can be stably placed on the hollow base shell 6. A second electric telescopic cylinder 71 is sleeved on the inner side of the hollow sleeve 7. The second electric telescopic cylinder 71 can stably telescopic within the hollow sleeve 7. An abutment rubber 72 is fixedly connected to the telescopic rod end of the second electric telescopic cylinder 71. When the telescopic rod of the second electric telescopic cylinder 71 telescopically extends and retracts, it can drive the abutment rubber 72 to telescopically extend and retract. When the abutment rubber 72 abuts against the inner wall of the concave rotating seat 2, the friction is increased by the rubber material of the abutment rubber 72, so that it can stably abut against the concave rotating seat 2 for placement.

[0044] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
