Description

Technical Field

[0001] The present invention relates to the technical field of dial grinding and processing, and in particular, to a multifunctional watch dial grinding device. Background Art

[0002] In the current watch production industry, during the production process of various precision components inside the watch, grinding is an essential process. At present, the structural design of domestic grinding equipment mainly relies on a large grinding wheel and the grinding stone on the bottom surface of the large grinding wheel for grinding. The rotation speed of the large grinding wheel is driven by a motor and a reduction motor, and the lifting of the large grinding wheel is driven by a cylinder. Due to the large centrifugal force of the large grinding wheel, it is easy to cause swing between the grinding wheels, resulting in uneven grinding planes, uneven thickness, broken feet of the dial, concave and convex feet, dented corners at the hole edges, scratches on the plane, etc. Especially the overall appearance of the dial completely fails to meet the requirements of high grades. During the grinding production process, due to the large grinding wheel and the small size of the product to be ground, it is easy to cause grooves or unevenness on the grinding stone, and the grinding stone needs to be frequently ground, thus causing unnecessary loss of the grinding stone.

[0003] For example, a special multi-head grinding wheel grinding machine for watch dials proposed in the application number CN201821203266.6 includes a machine body, a workbench is provided on the machine body, and a machine head is further provided above the workbench on the machine body. A control panel and a control box are also installed on the machine head; three grinding units arranged in parallel are installed on the machine head.

[0004] In the above application, the rotation speed of the grinding motors of the three grinding units and the air pressure of the lifting cylinders can be controlled separately. The rotation speeds of the grinding motors of the three grinding units and the air pressures of the lifting cylinders can be adjusted differently, so that better grinding effects can be achieved for dials of different materials. However, after the dial is ground, a large amount of dust will remain on the surface of the dial. When the worker takes it outside, the dust is easily scattered in the air, resulting in a deterioration of the working environment quality. Therefore, how to invent a multifunctional watch dial grinding device to improve these problems has become an urgent problem to be solved by those skilled in the art. Summary of the Invention

[0005] To make up for the above deficiencies, the present invention provides a multifunctional watch dial grinding device, aiming to improve the problem that the existing dial grinding device lacks measures to blow off the dust on the surface of the dial after grinding.

On the left side of the upper end face of the device base, there is a fixedly connected support frame. The lower end face of the support frame is fixedly connected with a grinding assembly through a lifting cylinder. On the upper end face of the device base, there is a fixedly connected electric control box. The electric control box is electrically connected to the lifting cylinder and the grinding assembly.

In the middle of the inner cavity of the base, there is a rotatably connected rotating column. The placement table is fixedly connected to the upper end face of the rotating column.

[0012] By adopting the above technical solution, by starting the servo motor to drive the rotating column to rotate the placement table, the watch dial placed on the placement table can be rotated, improving the efficiency of the blowing mechanism for blowing off the dust on the surface of the watch dial.

[0013] Preferably, the servo motor is electrically connected to the electric control box, and the output shaft end of the servo motor is fixedly connected to the rotating column.

[0014] Preferably, the clamping mechanism includes a sliding seat, a clamping seat, a connecting rod, a connecting sleeve, a limiting seat, a limiting column, a rack and a gear. In the inner cavity of each fixing seat, there is a fixedly connected sliding seat. On the upper end face of each sliding seat, there is a fixedly connected clamping seat. On the front and rear sides of the right part of the upper end face of the base, there are fixedly connected limiting seats. In the inner cavity of each limiting seat, there is a slidably connected limiting column. On the upper end face of each limiting column, there is a fixedly connected connecting rod. In the inner cavity of each connecting sleeve, there is a slidably connected connecting rod

[0015] By adopting the above technical solution, through the setting of the clamping mechanism, the watch dial can be clamped, ensuring its stability during grinding.

[0016] Preferably, the connecting rod on the front side is fixedly connected to the rack. On the outer side wall of the rotating column, there is a fixedly connected gear. The gear is meshed with the rack. The connecting rod slides in the inner cavity of the connecting sleeve. On the inner side wall of each clamping seat, there is a pressure sensor.

[0017] By adopting the above technical solution, through the setting of the pressure sensor, the dial can be clamped adaptively according to the force, avoiding damage to the dial caused by excessive force.

[0018] Preferably, the blowing mechanism includes a support rod, an air storage box, a piston plate, a return spring, a magnetic steel plate, an air inlet pipe and an air blowing pipe.

[0022] By adopting the above technical solution, through the cooperation of the air storage box and the two one-way air valves, the effect of replacing the use of an air pump for pressurization and inflation can be achieved, saving the production cost.

[0023] The beneficial effects of the present invention are as follows:

[0024] When the servo motor is started to drive the rotating column to rotate, with the cooperation of the clamping mechanism, the three clamping seats can approach each other. At this time, the clamping seats can realize the function of clamping the dial, ensuring the stability of the dial when the grinding assembly grinds the surface of the dial, improving the grinding quality. After the dial is ground, with the cooperation of the clamping mechanism and the blowing mechanism, at this time, the piston plate can squeeze the inner cavity of the air storage box, and finally high-pressure gas is ejected from the air blowing pipe to blow away the dust on the surface of the dial, avoiding the dust falling into the working environment of the worker when the worker takes the dial, resulting in a decline in the environmental quality of the worker and harm to the physical health of the worker, and improving the safety of the entire device.

[0035] Embodiment

[0036] Embodiment 1:

[0037] Referring to Figure 1-7 , a multifunctional watch dial grinding device includes a device base 1, a support frame 2, a lifting cylinder 3, and an electric control box 4. A support frame 2 is fixedly connected to the left side of the upper end surface of the device base 1. The lower end surface of the support frame 2 is fixedly connected to a grinding assembly through a lifting cylinder 3. An electric control box 4 is fixedly connected to the upper end surface of the device base 1. The electric control box 4 is electrically connected to the lifting cylinder 3 and the grinding assembly. It further includes a base 5 and a watch dial. Fixed seats 6 are fixedly connected to the periphery of the upper end surface of the base 5;

[0038] A rotating mechanism 7 is arranged in the middle of the inner cavity of the base 5. The rotating mechanism 7 is used to rotate the watch dial;

[0039] A clamping mechanism 8 is arranged in the inner cavity of the fixed seat 6. The clamping mechanism 8 is used to clamp the watch dial;

[0040] A blowing mechanism 9 is fixedly connected to the outer side of the upper end surface of the base 5. The blowing mechanism 9 is used to blow off the dust on the surface of the watch dial

[0041] Referring to Figure 1-3 , further; the rotating mechanism 7 includes a servo motor 71, a rotating column 72, and a placement table 73. A servo motor 71 is fixedly connected to the middle of the lower end surface of the base 5 through a frame. A rotating column 72 is rotatably connected to the middle of the inner cavity of the base 5. The placement table 73 is fixedly connected to the upper end surface of the rotating column 72. The servo motor 71 is electrically connected to the electric control box. The output shaft end of the servo motor 71 is fixedly connected to the rotating column 72.

[0042] It should be noted that: through the setting of the rotating mechanism 7, the rotating column 72 can drive the placement table 73 to rotate. At this time, the watch dial on the placement table 73 also rotates accordingly, improving the efficiency of the blowing mechanism 9 to blow off the dust on the surface of the watch dial.

[0043] Referring to Figure 1-4, Further, the clamping mechanism 8 includes a sliding seat 81, a clamping seat 82, a connecting rod 83, a connecting sleeve 84, a limiting seat 85, a limiting column 86, a rack 87 and a gear 88. A sliding seat 81 is fixedly connected to the inner cavity of each fixed seat 6, and a clamping seat 82 is fixedly connected to the upper end surface of each sliding seat 81. The front and rear sides of the right part of the upper end surface of the base 5 are fixedly connected with limiting seats 85. A limiting column 86 is slidably connected to the inner cavity of each limiting seat 85, and a connecting rod 83 is fixedly connected to the upper end surface of each limiting column 86. A connecting rod 83 is slidably connected to the inner cavity of each connecting sleeve 84. The connecting rod 83 located on the front side is fixedly connected with the rack 87. The outer side wall of the rotating column 72 is fixedly connected with a gear 88, and the gear 88 is meshed with the rack 87. The connecting rod 83 slides in the inner cavity of the connecting sleeve 84, and a pressure sensor is arranged on the inner side wall of each clamping seat 82.

[0044] It should be noted that when the servo motor 71 drives the rotating column 72 to rotate, at this time, with the cooperation of the clamping mechanism 8, the three clamping seats 82 can move closer to each other. At this time, the clamping seat 82 can realize the function of clamping the dial, ensuring the stability of the dial when the grinding assembly grinds the surface of the dial and improving the grinding quality.

[0045] Refer to Figure 1-7 , Further, the blowing mechanism 9 includes a support rod 91, an air storage box 92, a piston plate 93, a return spring 94, a magnetic steel plate 95, an air inlet pipe 96 and an air blowing pipe 97. The support rod 91 is fixedly connected to the outer side of the upper end surface of the base 5, and the support rod 91 is fixedly connected with the air storage box 92. The right end face of the inner cavity of the air storage box 92 is fixedly connected with the return spring 94, and the other end of the return spring 94 is fixedly connected with the piston plate 93. The piston plate 93 slides in the inner cavity of the air storage box 92. The upper end surface of the connecting sleeve 84 is fixedly connected with the magnetic steel plate 95, and the magnetic steel plate 95 is magnetically connected with the piston plate 93. The upper end surface of the air storage box 92 is fixedly connected with the air blowing pipe 97. A one-way air valve with an outlet towards the air blowing pipe 97 end is arranged at the connection between the air blowing pipe 97 and the air storage box 92. The front and rear end faces of the air storage box 92 are fixedly connected with the air inlet pipe 96, and a one-way air valve with an outlet towards the air storage box 92 end is arranged at the connection between the air inlet pipe 96 and the air storage box 92.

[0046] It should be noted that after the dial is ground, with the cooperation of the clamping mechanism 8 and the blowing mechanism 9, at this time, the piston plate 93 can squeeze the inner cavity of the air storage box 92, and finally, the high-pressure gas is ejected from the air blowing pipe 97 to blow off the dust on the surface of the dial, avoiding the dust falling into the working environment of the worker when the worker takes the dial, which causes the decline of the environmental quality of the worker and endangers the physical health of the worker, and improving the safety of the whole device.

[0047] The working principle of this multifunctional watch dial grinding device:

[0048] It should be noted that the entire device is arranged inside a cover with a sealing effect. When the dial to be processed needs to be processed, the staff first place the dial to be processed on the placement table 73. At this time, by starting the servo motor 71, the rotating column 72 rotates. Since the rotating column 72 is fixedly connected to the gear 88, the gear 88 will drive the rack 87 to move. The rack 87 will drive the limit post 86 to move to the left side of the inner cavity of the limit seat 85, and the connecting rod 83 will move into the inner cavity of the connecting sleeve 84, so that the three sliding seats 81 will also move to the left side of the inner cavity of the fixed seat 6 at the same time. Since the sliding seat 81 is fixedly connected to the clamping seat 82, at this time, the three clamping seats 82 will be able to approach each other simultaneously, and under the action of the pressure sensor, the clamping seat 82 can realize the function of safely clamping the dial to be processed, ensuring the stability of the dial when the grinding assembly grinds the surface of the dial and improving the grinding quality;

[0049] Embodiment 2: The difference between this embodiment and Embodiment 1 is that:

[0050] After the dial is ground, by starting the servo motor 71 to reverse the rotating column 72. At this time, under the cooperation of the gear 88 and the rack 87, etc., the limit post 86 will drive the connecting rod 83 to move to the outer side of the inner cavity of the limit seat 85. When the magnetic steel plate 95 moves to the right side of the air storage box 92 (as Figure 7 shown), at this time, the magnetic steel plate 95 can drive the piston plate 93 to move to the right side of the inner cavity of the air storage box 92. The piston plate 93 can squeeze the air inside the air storage box 92. When the air inside the air storage box 92 is greater than the threshold of the one-way air valve at the air blowing pipe 97, the high-pressure air will be able to be discharged from the air blowing pipe 97 (at this time, the servo motor 71 can drive the rotating column 72 to rotate the dial on the placement table 73). Then, the entire device can blow off the dust on the surface of the dial, avoiding the dust falling into the working environment of the worker when the worker takes the dial, resulting in a decline in the environmental quality of the worker and causing harm to the physical health of the worker, improving the safety of the entire device. When clamping the next dial to be processed, start the servo motor 71 to rotate the rotating column 72 forward, so that the limit post 86 will drive the connecting rod 83 to move into the inner cavity of the limit seat 85. When the magnetic steel plate 95 moves to the left side of the air storage box 92 (as Figure 6 shown), the magnetic steel plate 95 can drive the piston plate 93 to move to the left side of the inner cavity of the air storage box 92. At this time, the available area of the cavity of the air storage box 92 becomes larger, and the internal air pressure becomes smaller. When the pressure is less than the threshold of the one-way air valve at the air inlet pipe 96, the external air can supplement the air inside the air storage box 92, making preparations for the next cleaning.

[0051] It should be noted that the specific model and specification of the motor need to be selected according to the actual specifications of the device, etc. The specific selection calculation method uses the existing technology in the field, so it will not be elaborated in detail.

[0052] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
