Description

Technical Field

[0001] This utility model relates to the technical field of thermos cup production equipment, and in particular to a rotary clamping mechanism and a grinding machine. Background Technology

[0002] Currently, the grinding process for most thermos cups involves manual processing of the cup rim using sandpaper. When loading, unloading, and grinding are done manually, production efficiency is limited by manpower and cannot be effectively improved, while costs increase. During the loading and unloading process, some thermos cups are exposed to high temperatures or acidic / alkaline conditions, which can harm bodily functions. Long-term exposure to this environment can lead to occupational diseases such as pneumoconiosis and finger joint deformities caused by the metal dust generated during grinding, seriously affecting health.

[0003] Some thermos cups employ automated grinding processes for their rims. For example, CN222958209U discloses an automated grinding device for thermos cups, comprising a detachably connected grinding machine body and a dust collection water tank. The grinding machine body includes a housing mechanism; a thermos cup rotation mechanism, at least one grinding mechanism, and a dust collection mechanism, all mounted on the housing mechanism. The grinding mechanism includes a longitudinal motion component; a transverse motion component slidably mounted on the longitudinal motion component; a grinding component, drivenly connected to the transverse motion component, which includes a support mechanism; a sanding belt turntable and a sanding belt take-up mechanism, both rotatably mounted on the support mechanism; a coarse grinding mechanism movably mounted on the support mechanism and in contact with the sanding belt roll on the sanding belt turntable; and a fine grinding mechanism mounted on the coarse grinding mechanism. While this technical solution enables automated grinding, the thermos cup body is directly mounted on the rotating spindle, making it prone to wobbling and shifting, thus affecting the grinding effect. Therefore, a rotating clamping mechanism and a grinding machine are provided to address these issues. Utility Model Content

[0004] One of the purposes of this utility model is to provide a rotary clamping mechanism and a grinding machine to solve the problem of wobbling and displacement that occurs when the thermos cup body is directly sleeved on the rotating spindle.

[0031] Please see Figures 1-6 As shown, the present invention provides a rotary clamping mechanism 1, which includes a rotary spindle assembly 10 and a clamping assembly 20. The thermos cup is placed on the rotary spindle assembly 10, and the rotary spindle assembly 10 drives the thermos cup to rotate. The clamping assembly 20 is disposed on the rotary spindle assembly 10 and clamps the thermos body disposed on the rotary spindle assembly 10, thereby effectively preventing the thermos cup from shaking or shifting.

The fixed plate 11 serves as a support body and is fixedly mounted on the main body of the grinding machine. The spindle mechanism 12 is rotatably mounted through the fixed plate 11, and a rotating motor drives the spindle mechanism 12 to rotate relative to the fixed plate 11. The pulley 13 is fixedly connected to the spindle mechanism 12, and the rotating motor drives the pulley 13 and the spindle mechanism 12 to rotate sequentially via a transmission belt. The top plate mechanism 14 is tractively connected to one end of the spindle mechanism 12 and is mounted through the clamping assembly 20. It moves with the spindle mechanism 12, and the thermos cup is placed on the top plate mechanism 14. The conductive slip ring 15 is mounted on the other end of the spindle mechanism 12 and is positioned opposite to the top plate mechanism 14. The conductive slip ring 15 provides electrical energy to the clamping assembly 20.

[0033] Please see Figure 3 As shown, in this embodiment, the spindle mechanism 12 includes a sleeve 121, multiple bearings 122, and a spindle body 123. The sleeve 121 is a hollow cavity, which is fixedly disposed on the fixed plate 11. The multiple bearings 122 are sequentially disposed in the sleeve 121. The spindle body 123 is rotatably disposed on the sleeve 121 through the multiple bearings 122. The pulley 13 is fixedly disposed on the spindle body 123.

Specifically, the spindle body 123 is provided with an external thread 1231, and the pulley 13 is fixedly threaded to the spindle body 123 through the external thread 1231. In this embodiment, the top plate mechanism 14 includes a support rod 141 and a top plate body 142; the support rod 141 is connected to the main shaft body 123 and moves with the movement of the main shaft body 123; the top plate body 142 is fixedly connected to the support rod 141, and the thermos cup is placed on the top plate body 142.

[0034] Please see Figure 1 , Figure 2 and Figure 4As shown, the clamping assembly 20 includes a support mechanism 21 and multiple clamping mechanisms. The support mechanism 21 is disposed through the rotating spindle assembly 10, and the multiple clamping mechanisms are arranged longitudinally on the support mechanism 21. These clamping mechanisms clamp different parts of the insulated cup body disposed on the top plate body 142, effectively preventing the insulated cup body from shaking or shifting. In this embodiment, the clamping assembly 20 includes a support mechanism 21, a first clamping mechanism 22, and a second clamping mechanism 23. The first clamping mechanism 22 and the second clamping mechanism 23 are arranged longitudinally on the support mechanism 21, clamping the upper and lower parts of the insulated cup body disposed on the top plate body 142 respectively. In other embodiments, the number of clamping mechanisms 22 can be three, four, or other multiples, depending on actual needs. Specifically, the support mechanism 21 includes a support base plate 211 and multiple support side plates 212. The support base plate 211 is disposed through the main shaft body 123. The multiple support side plates 212 are vertically fixedly connected to the support base plate 211, and the first clamping mechanism 22 and the second clamping mechanism 23 are respectively connected to the multiple support side plates 212.

The active gripper structure 223 and the multiple driven gripper structures 224 are sequentially and movably connected to the mounting plate 221. The active gripper structure 223 is connected to the drive structure 222. The drive structure 222 drives the active gripper structure 223 to move, which in turn drives the multiple driven gripper structures 224 to move sequentially, thereby clamping the insulation body placed on the top plate mechanism 14. It can clamp insulation bodies of different sizes. In this embodiment, three driven gripper structures 224 are sequentially and circumferentially connected to the active gripper structure 223. In other embodiments, the number of driven gripper structures 224 can be two, four, or other plurality of structures, depending on actual needs.

[0036] Please see Figure 5As shown, specifically, a mounting side plate 2211 is fixedly mounted on the mounting plate 221, and a drive structure 222 is mounted on the mounting side plate 2211. In this embodiment, the drive structure 222 includes a drive motor 2221, a worm gear 2222, and a drive gear 2223; the drive motor 2221 is mounted on the mounting side plate 2211 and can rotate in both directions; the worm gear 2222 is driven to the rotating shaft of the drive motor 2221; the drive gear 2223 is driven to the worm gear 2222 and is also driven to the active gripper structure 223. The drive motor 2221 drives multiple driven gripper structures 224 to move sequentially through the worm gear 2222, the drive gear 2223, and the active gripper structure 223, thereby clamping or releasing the insulation body placed on the top plate mechanism 14.

[0037] Please see Figure 5 As shown in Figure 6, specifically, the active gripper structure 223 includes a gripper body 2231, a rack 2232, and a connecting rod 2333. The gripper body 2231 is movably connected to the mounting plate 221. The rack 2232 is fixedly mounted on the gripper body 2231 and meshes with the drive gear 2223 for transmission. The drive motor 2221 drives the gripper body 2231 to move sequentially through the worm gear 2222, the drive gear 2223, and the rack 2232. One end of the connecting rod 2333 is movably connected to the gripper body 2231, and the other end is connected to the adjacent driven gripper structure 224 for transmission. In this embodiment, the structure of the driven gripper structure 224 is similar to that of the active gripper structure 223, so its specific structure will not be described in detail here.

[0038] Please see Figure 1 , Figure 2 and Figure 4 As shown, in this embodiment, the structure of the second clamping mechanism 23 is the same as that of the first clamping mechanism 22, so its specific structure will not be described in detail here.

[0039] Please see Figure 7 As shown, a grinding machine includes at least one of the above-described rotary clamping mechanisms 1.

[0040] It should be noted that the specific working process of a rotary clamping mechanism and a grinding machine is as follows: First, the thermos cup body is placed on the top plate mechanism 14. Then, the drive motors 2221 on the first clamping mechanism 22 and the second clamping mechanism 23 synchronously drive multiple driven gripper structures 224 to move through the worm gear 2222, drive gear 2223, and active gripper structure 223 in sequence to clamp the thermos body placed on the top plate mechanism 14. Finally, the rotating motor drives the pulley 13, the main shaft mechanism 12, and the top plate mechanism 14 to rotate through the transmission belt in sequence, thereby realizing the rotary clamping operation of the thermos cup body placed on the top plate mechanism 14.

[0041] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
