[0002] As precision instruments, watches are widely used in daily life, business settings, and even specialized fields. They not only display the basic time but can also be equipped with a variety of complex functions, such as chronographs, alarms, and calendar displays. Therefore, the quality of a watch directly impacts user satisfaction and brand image.

[0003] During the watch production process, in order to ensure the beauty and durability of the product, some parts often need to be finely ground and polished. These parts, such as the watch case and bottom case, can not only remove burrs and scratches on the surface of the parts, but also give the product a smoother and brighter appearance, thereby improving the overall product grade.

[0004] However, in the traditional manual grinding and polishing process, workers install the workpiece on the machine tool and carefully grind the workpiece with handheld sandpaper and other tools to remove burrs and scratches on the workpiece surface. However, since workers need to keep their hands stable for a long time during the operation, it is easy for workers to experience arm fatigue and muscle tension, which in turn affects work efficiency and product quality.

[0005] Therefore, it is necessary to propose a new technical solution to solve the above problems. Utility Model Content

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] See also Figure 1-3 A grinding and polishing device for watch production includes a workbench 1, a driving mechanism 2 is installed on the workbench 1, a main shaft 21 is provided on one side of the driving mechanism 2, an inner expansion chuck 22 is installed on the main shaft 21, and a protective frame 3 is provided around the upper edge of the workbench 1;

[0034] The inner expansion chuck 22 is mounted on the main shaft 21 of the driving mechanism 2, and the watch workpiece is clamped and fixed by the inner expansion chuck 22. Then, by starting the driving mechanism 2, the main shaft 21 drives the inner expansion chuck 22 and the workpiece to rotate. Then, the staff can use sandpaper or other tools to grind and polish the workpiece.

[0035] During work, the workbench 1 is surrounded by the protective frame 3, so that the staff can use the remaining space of the workbench 1 to place some commonly used tools, which can prevent tools from accidentally falling from the workbench 1 and causing injuries to the staff;

[0036] Preferably, a fixed base 4 is provided at the upper end of the workbench 1, two screws 41 are axially connected to the two sides of the fixed base 4, and a movable block 42 is screwed on the two screws 41. A sleeve 43 is fixed on the movable block 42, and a telescopic rod 44 is screwed inside the sleeve 43. The telescopic rod 44 is provided with a steering portion 45, and a hand support plate 46 is fixed on the steering portion 45;

[0037] Guide portions 47 are respectively provided on both sides of the fixing base 4 , and the two movable blocks 42 are guided and slid on the guide portions 47 .

[0038] Specifically, when a worker is grinding and polishing a workpiece clamped by the inner expansion chuck 22, the worker can place his arms on the two hand support plates 46. The hand support plates 46 are fixedly supported on the movable block 42 through the telescopic rod 44 and the sleeve 43, thereby providing support for the worker's arms, thereby significantly reducing arm fatigue and muscle tension caused by long-term work, thereby improving work efficiency and quality.

[0039] In order to accommodate workers of different body shapes, the positions of the movable blocks 42 screwed to the screws 41 are adjusted by rotating the screw rods 41 axially connected to the fixed base 4. The setting of the guide portion 47 can prevent the movable block 42 from rotating along with the rotation of the screw rod 41, so that the movable block 42 can be displaced laterally along with the rotation of the screw rod 41 in different directions. By rotating the two screw rods 41 respectively, the positions of the two movable blocks 42 are adjusted, and the positions of the two hand support plates 46 are adjusted, so that workers of different body shapes can adjust the positions of the two hand support plates 46 to the optimal positions.

[0040] Furthermore, the staff can also rotate the telescopic rod 44. Since the telescopic rod 44 is screwed inside the sleeve 43, the telescopic rod 44 can drive the hand support plate 46 to be raised and lowered when the telescopic rod 44 is rotated, so that the height of the hand support plate 46 can be adapted to the height of staff of different body shapes. After the height position of the hand support plate 46 is adjusted, the hand support plate 46 can be rotated to a suitable position using the turning portion 45 between the telescopic rod 44 and the hand support plate 46.

[0041] By adjusting the lateral position and the height position of the hand support plate 46 , the hand support plate 46 can be adapted to be used by workers of different body shapes, thereby further improving the comfort brought by the hand support plate 46 .

[0042] Preferably, the steering portion 45 includes a universal ball 451 fixedly connected to the telescopic rod 44 , a steering sleeve 452 is sleeved on the universal ball 451 , and the steering sleeve 452 is fixedly connected to the hand support plate 46 .

[0043] Specifically, the hand support plate 46 is mounted on the universal ball 451 through a fixed steering sleeve 452, so that the hand support plate 46 can be steered at different angles. The effect is that when the staff is grinding and polishing the workpiece at different positions and angles, their arms can be adjusted according to the movements of their hands, such as changes in the angle of the arm, and at the same time, the support effect of the arm can be maintained, making the staff's operation more relaxed and comfortable.

[0044] Preferably, the guide portion 47 includes two guide rods 471 fixed to both sides of the fixed seat 4, the movable block 42 is provided with a guide hole, the movable block 42 is slidably connected to the guide rod 471 through the guide hole, and a linear bearing 472 is provided between the guide hole and the guide rod 471.

[0045] Specifically, when the rotation of the screw 41 causes the movable block 42 to move, the function of the guide rod 471 is to provide directional movement for the movable block 42. During the movement of the movable block, the linear bearing 472 between the guide hole and the guide rod 471 can reduce the friction between the movable block 42 and the guide rod 471, thereby making the movement of the movable block 42 smoother.

[0046] Preferably, the two guide rods 471 extend to opposite sides and are fixed to the protective frame 3 .

[0047] Specifically, the fixed connection between the guide rod 471 and the protective frame 3 can improve the stability of the guide rod 471, thereby improving the stability of the movable block 42 during movement.

[0048] Preferably, through holes 31 are opened on both sides of the protective frame 3 corresponding to the screw rod 41 , and the screw rod 41 passes through the through holes 31 and is connected to the rocker 411 .

[0049] Specifically, the screw 41 is raised and passes through the through hole 31, and the through hole 31 is used to support the other end of the screw 41 and the fixing seat 4, so as to improve the stability of the screw 41 when in use. At the same time, by adding the rocker 411, it is easier to control the rotation of the screw 41.

[0050] Preferably, the hand support plate 46 is arranged in an arc-shaped structure.

[0051] Specifically, the hand support plate 46 with an arc-shaped structure can fit the worker's arm more closely, and also makes the hand support plate 46 adaptable to a wider range of arm sizes.

[0052] Preferably, a soft pad 5 is provided on the inner surface of the palm support plate 46 .

[0053] Specifically, the provision of the soft pad 5 can further improve the comfort of the hand support plate 46 and also prevent the arm from slipping due to sweat.

[0054] Furthermore, a base 6 is provided at the upper end of the driving mechanism 2 , a connecting pipe 61 is connected to the base 6 , an end of the connecting pipe 61 is connected to a lighting lamp 62 , and the lighting lamp 62 illuminates the inner expansion chuck 22 .

[0055] Specifically, when the workpiece is being ground and polished, the lighting lamp 62 connected to the base 6 and the connecting tube 61 is used to mechanically illuminate the workpiece clamped by the inner expansion chuck 22, which can provide the staff with a good working field of vision, so that they can better penetrate the defects on the surface of the workpiece to reduce the occurrence of defective products.

[0056] Preferably, the connecting pipe 61 is a metal shaped hose.

[0057] Specifically, the connecting pipe 61 is made of a metal shaped hose so that the staff can adjust the position and direction of the lighting lamp 62 at will, and the position can be fixed after the adjustment is completed.
