Description

Technical Field

[0001] This utility model relates to the field of grinding wheel switching technology, specifically a multifunctional grinding machine device for rapid grinding wheel switching. Background Technology

[0002] In the fields of machining and surface treatment, grinding equipment is an indispensable tool, widely used in the processing of various metal and non-metal materials to achieve surface finishing, deburring, or shaping of specific workpieces. As industrial production demands increasing efficiency and precision, the functionality and flexibility of grinding equipment have become crucial indicators of its performance.

[0003] However, in existing technologies, traditional grinding equipment often faces the problem of cumbersome and time-consuming wheel replacement. When it is necessary to change to different specifications of grinding wheels to meet different grinding needs, it is usually necessary to shut down the entire machine, disassemble the original grinding wheel, and install the new one. This process not only increases downtime and reduces production efficiency, but may also lead to a decrease in equipment accuracy due to frequent disassembly and installation. In addition, some grinding equipment also has shortcomings in the connection method of the grinding wheel, making it inconvenient to replace the worn grinding wheel, further affecting the efficiency of the equipment. Therefore, those skilled in the art provide a multifunctional grinding machine device with rapid wheel switching to solve the problems mentioned in the background art. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] This utility model provides a technical solution: a multifunctional grinding machine device with rapid wheel switching. Please refer to [link / reference]. Figures 1 to 5 The system includes a workbench 1, a support 2 mounted on the workbench 1, a ring 3 mounted on the upper end of the support 2, a turntable 8 mounted on the front side of the ring 3, a retaining ring 9 mounted on the rear side of the turntable 8, a motor 6 mounted on the support 2, a drive gear 7 connected to the output end of the motor 6 facing the turntable 8, the drive gear 7 being located at an eccentric position inside the turntable 8, a driven gear 13 mounted on the inner circumference of the turntable 8, a rotating shaft 11 mounted on the central axis of the driven gear 13, a sleeve 15 fitted at the front end of the rotating shaft 11, a second bolt 16 connected to the side wall of the sleeve 15, a grinding wheel 14 mounted on the front side of the sleeve 15, an L-shaped support arm 4 mounted on one side of the ring 3, a first bolt 5 connected to the L-shaped support arm 4, and a first screw hole 10 opened on the outer circumference of the turntable 8.

[0023] Please see Figures 1 to 5The motor 6 is fixedly installed on the bracket 2. The motor 6 is driven by the drive gear 7. The drive gear 7 meshes with the driven gear 13 below. The rotating shaft 11 is rotatably engaged with the front and rear side walls of the turntable 8. When the motor 6 drives the drive gear 7 to rotate, the driven gear 13 meshing with the drive gear 7 drives the corresponding grinding wheel 14 to rotate through the rotating shaft 11 and the sleeve 15. A second threaded hole 12 is provided on the front side wall of the rotating shaft 11. The sleeve 15 is threadedly connected to the second threaded hole 12 on the rotating shaft 11 through a second bolt 16. This structure allows for quick disassembly and replacement when the grinding wheel 14 wears. The first bolt 5 is threadedly connected to the first screw hole 10 on the outer side wall of the turntable 8. When it is necessary to change to a grinding wheel 14 of other specifications according to the grinding situation, the first bolt 5 on the L-shaped support arm 4 on one side of the ring sleeve 3 is unscrewed so that it is disconnected from the first screw hole 10 on the outer side wall of the turntable 8. At this time, the turntable 8 can be rotated, and the grinding wheel 14 to be used can be moved to the position below the turntable 8 with the rotation of the turntable 8, so that the driven gear 13 and the driving gear 7 mesh and contact. Then the first bolt 5 is tightened again to fix the turntable 8 through the first bolt 5, thereby completing the effect of adjusting the grinding wheel specifications.

[0024] In this utility model, a support 2 is installed on the worktable 1 of the grinding machine. A ring 3 is installed on the upper end of the support 2, and a turntable 8 is set on the front side of the support 2. A retaining ring 9 is installed on the rear side of the turntable 8. The ring 3 is rotatably engaged with the retaining ring 9, thereby providing rotational support for the turntable 8. A motor 6 is also installed on the support 2. The output end of the motor 6 towards the turntable 8 drives a drive gear 7. The drive gear 7 is eccentrically positioned inside the turntable 8, with the eccentric position facing downwards. A driven gear 13 is set inside the turntable 8. Multiple driven gears 13 are evenly distributed on the inner periphery of the turntable 8. Because the drive gear 7 is positioned low, the driven gears 13 can only mesh with the drive gear 7 when they are located at the lower inner part of the turntable 8.

[0025] A rotating shaft 11 is longitudinally mounted in the middle of the driven gear 13. The rotating shaft 11 rotates through the turntable 8. A second screw hole 12 is provided on the side wall of the part of the rotating shaft 11 that protrudes from the turntable 8. A sleeve 15 is sleeved on the front end of the rotating shaft 11. A grinding wheel 14 is installed on the front end of the sleeve 15. A second bolt 16 is connected to the sleeve 15. The sleeve 15 and the rotating shaft 11 can be fixed by connecting the second bolt 16 and the second screw hole 12. When the motor 6 drives the driving gear 7 to rotate, the driven gear 13 that meshes with the driving gear 7 drives the corresponding grinding wheel 14 to rotate through the rotating shaft 11 and the sleeve 15. This structure can be quickly disassembled and replaced when the grinding wheel 14 is worn.

[0026] Since there are multiple driven gears 13, and the grinding wheels 14 installed on each shaft 11 through the sleeve 15 are of different specifications, a multi-functional effect can be achieved.

[0027] When it is necessary to replace the grinding wheel 14 with another specification according to the grinding situation, unscrew the first bolt 5 on the L-shaped support arm 4 on one side of the ring sleeve 3 to disengage it from the first screw hole 10 on the outer wall of the turntable 8. At this time, the turntable 8 can be rotated, and the grinding wheel 14 to be used can be moved to the position below the turntable 8 as the turntable 8 rotates, so that the driven gear 13 meshes with the driving gear 7. Then, tighten the first bolt 5 again to fix the turntable 8. Then, the motor 6 restarts and drives the replaced grinding wheel 14 to rotate and grind through the cooperation of the driving gear 7 and the driven gear 13. This structure makes the equipment able to replace the grinding wheel 14 quickly without long-term downtime, thus improving grinding efficiency.
