Description

Technical Field

[0001] This utility model relates to the field of ceramic bearing technology, and in particular to a ceramic bearing material handling tweezers. Background Technology

[0002] Ceramic bearings are high-end bearing products with special properties and wide applications. They are typically made of advanced ceramic materials such as silicon nitride (Si3N4) and zirconium oxide (ZrO2) to manufacture rolling elements and inner and outer rings. The hardness of ceramic materials is much higher than that of metals, enabling them to work for a long time under high load and high speed conditions, reducing wear and extending service life. They are used in many high-tech and high-requirement industries such as aerospace, machine tools, medical devices, new energy vehicles, petrochemicals, and semiconductor manufacturing. During the material handling process, tweezers are used to assist manual handling of ceramic bearings.

[0003] Existing technologies, such as the utility model with authorization announcement number CN203751992U, disclose a tweezers belonging to the field of clamping instrument technology. It includes two opposing tweezer handles, one end of which is connected together, and the other end of each handle is connected to a claw. The opposing surfaces of the two handles are provided with a first anti-slip texture for gripping. The opposing surfaces of the two claws have raised and recessed teeth. A heat-insulating sleeve is fitted onto each handle at the position of the first anti-slip texture. The tweezers provided by this utility model, when the claws come into contact with a high-temperature reagent, although the high temperature of the reagent is rapidly transferred to the handles through the claws, causing the handle temperature to rise rapidly, is mitigated by the heat insulation effect of the sleeve. This design prevents heat transfer to the fingers, effectively avoiding the problem of fingers being unable to grip the tweezers handle due to high temperatures, causing reagents to fall and become unusable. It also avoids the risk of finger burns. This design addresses the issue of existing tweezers, which consist of a handle and claws fixed to the handle. The handle is used to apply clamping force, and the claws are used to hold objects. In laboratory experiments, sometimes tweezers are used to hold high-temperature reagents directly for convenience. However, since the handle and claws are generally made of metal, when the claws come into contact with high-temperature reagents, the high temperature of the reagent is quickly transferred through the claws to the handle, causing the handle temperature to rise rapidly. This makes it impossible for the fingers to grip the handle, causing them to release the tweezers and the reagent to fall. This not only renders the reagent unusable but also easily burns the fingers.

[0004] In daily work, it has been found that the existing ceramic bearing picking tweezers have a simple structure and cannot meet the gripping needs of ceramic bearings of different sizes. For larger ceramic bearings, the gripping part may not be long enough to grip them securely, while for smaller ceramic bearings, the gripping part may be too long and cause inconvenience in operation. This leads to the problem that the existing ceramic bearing picking tweezers have a simple structure and are not easy to adjust. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as simple structure and inconvenience in adjustment, by proposing a ceramic bearing material handling tweezers.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a ceramic bearing picking tweezers, comprising a tweezers body and an adjustment device. The surface of the tweezers body is provided with two sets of tweezers heads. The adjustment device is disposed on the surface of the tweezers heads, and includes an adjustment head. An adjustment groove is formed on the surface of the tweezers head, and the adjustment head is slidably connected to the inner wall of the adjustment groove. A through hole is formed on the surface of the tweezers head, and the through hole communicates with the inner wall of the adjustment groove. A push block is fixedly connected to the surface of the adjustment head, and the push block is slidably connected to the inner wall of the through hole. A limit component is provided in the push block. Through these components, when adjustment is required, the push block in the through hole can be pushed, causing the adjustment head to slide in the adjustment groove, thereby adjusting the length of the tweezers head gripping part and enabling the gripping of ceramic bearings of different sizes.

[0007] Preferably, the surface of the adjusting head is fixedly connected with an anti-slip pad, and there are multiple anti-slip pads. The multiple anti-slip pads are arranged at equal intervals on the adjusting head. With the above-mentioned components, when the adjusting head is used in conjunction with the tweezers head for clamping, the anti-slip pads can improve the overall anti-slip effect, making it safer and more stable when picking up ceramic bearings.

[0008] Preferably, the limiting component includes a slide rod, which is slidably connected to the inner wall of the push block. A pressing ring and a locking rod are fixedly connected to both ends of the slide rod, respectively. The pressing ring and the locking rod are slidably connected to the inner wall of the push block. A slot is formed in the inner wall of the perforation, and the locking rod engages with the inner wall of the slot. A spring is sleeved on the surface of the slide rod, and both ends of the spring are fixedly connected to the inner walls of the pressing ring and the push block, respectively. During adjustment, the pressing ring is first pushed, causing the slide rod and the locking rod to move. The spring is stressed, and the locking rod loses its restraint on the slot. The push block then moves the adjusting head. After moving to a certain position, the pressing ring is released, and the spring causes the pressing ring and the locking rod to reset. The locking rod can then engage in the slot, achieving the limiting function.

[0009] Preferably, the card slot is formed by a straight groove for the card rod to slide through and a plurality of limiting groove assemblies for the card rod to engage.

[0010] Preferably, the surface of the tweezers body is provided with an auxiliary device, which includes a screw fixedly connected to the surface of the tweezers body. The surface of the tweezers body has a moving hole through which the screw passes. A threaded ring is threadedly connected to the surface of the screw, and a handle is fixedly connected to the surface of the threaded ring. There are three handles. With the above components, when it is necessary to clamp the ceramic bearing for a long time, the threaded ring can be rotated by the handle. The threaded ring rotates in the screw, and then the threaded ring squeezes the tweezers body. The tweezers head can cooperate with the tweezers body to clamp stably, reducing the manual burden.

[0011] Preferably, a positioning ring is fixedly connected to one end of the screw. Through the above-mentioned components, the positioning ring can play a role in intercepting and protecting the threaded ring.

[0012] Preferably, a pressure plate is fitted onto the surface of the screw, and the pressure plate is positioned between the threaded ring and the tweezers body. Through the above-mentioned components, the threaded ring can be squeezed by the pressure plate and the tweezers body, thereby improving the overall stability.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] In this invention, by setting an adjustment device, it can adapt to ceramic bearings of different specifications and sizes. Whether it is a small, medium or large ceramic bearing, stable and accurate clamping can be achieved by adjusting the length of the clamping part, reducing the trouble of frequently changing tools due to mismatch between the tweezers and the bearing size.

[0015] In this invention, by setting an auxiliary device, when it is necessary to grip the ceramic bearing for a long time, there is no need for manual hand to exert force to grip it, which reduces the manual burden and improves ease of use. Attached Figure Description

[0023] Please see Figures 1-5 This utility model provides a technical solution: a ceramic bearing picking tweezer, including a tweezer body 1 and an adjustment device 3. Two sets of tweezer heads 2 are provided on the surface of the tweezer body 1, and the adjustment device 3 is provided on the surface of the tweezer heads 2.

[0024] Specifically, the adjustment device 3 includes an adjustment head 31, an adjustment groove 35 is provided on the surface of the tweezers head 2, the adjustment head 31 is slidably connected to the inner wall of the adjustment groove 35, a through hole 36 is provided on the surface of the tweezers head 2, the through hole 36 is connected to the inner wall of the adjustment groove 35, a push block 33 is fixedly connected to the surface of the adjustment head 31, the push block 33 is slidably connected to the inner wall of the through hole 36, and a limit component 34 is provided in the push block 33.

[0025] In this implementation scheme: when adjustment is required, the push block 33 in the perforation 36 can be pushed, and the push block 33 can drive the adjustment head 31 to slide in the adjustment groove 35, thereby adjusting the length of the clamping part of the tweezers head 2, which can clamp ceramic bearings of different sizes.

[0026] Specifically, an anti-slip pad 32 is fixedly connected to the surface of the adjusting head 31. There are multiple anti-slip pads 32, which are evenly spaced on the adjusting head 31. When the adjusting head 31 is used in conjunction with the tweezers head 2 for clamping, the anti-slip pads 32 can improve the overall anti-slip effect, making it safer and more stable when picking up ceramic bearings.

[0027] Specifically, the limiting component 34 includes a slide rod 342, which is slidably connected to the inner wall of the push block 33. A pressing ring 341 and a locking rod 343 are fixedly connected to both ends of the slide rod 342, respectively. The pressing ring 341 and the locking rod 343 are slidably connected to the inner wall of the push block 33. A slot 346 is provided on the inner wall of the through hole 36, and the locking rod 343 is engaged with the inner wall of the slot 346. A spring 345 is sleeved on the surface of the slide rod 342, and both ends of the spring 345 are fixedly connected to the pressing ring 341 and the inner wall of the push block 33, respectively.

[0028] In this implementation scheme: During the adjustment process, the pressing ring 341 is first pushed, which drives the slide bar 342 and the locking rod 343 to move. The spring 345 is under force, and at this time the locking rod 343 loses its restraint on the locking groove 346. The adjusting head 31 is driven to move through the push block 33. After moving to a certain position, the pressing ring 341 is released, and the spring 345 drives the pressing ring 341 and the locking rod 343 to reset. The locking rod 343 can then be locked into the locking groove 346 to achieve the limiting function.

[0029] Specifically, the card slot 346 is formed by a straight groove for the card rod 343 to slide through and a plurality of limiting groove assemblies for the card rod 343 to engage.

[0030] Specifically, the surface of the tweezers body 1 is provided with an auxiliary device 4, which includes a screw 41. The screw 41 is fixedly connected to the surface of the tweezers body 1. The surface of the tweezers body 1 is provided with a moving hole 42 for the screw 41 to pass through. The surface of the screw 41 is threadedly connected with a threaded ring 44. The surface of the threaded ring 44 is fixedly connected with a handle 45. There are three handles 45.

[0031] In this implementation scheme: when it is necessary to clamp the ceramic bearing for a long time, the threaded ring 44 can be rotated by the handle 45. The threaded ring 44 rotates in the screw 41, and then the threaded ring 44 squeezes the tweezers body 1. The tweezers head 2 can cooperate with the tweezers body 1 to clamp stably, reducing the manual burden.

[0032] Specifically, a positioning ring 43 is fixedly connected to one end of the screw 41, and the positioning ring 43 can intercept and protect the threaded ring 44.

[0033] Specifically, a pressure plate 46 is sleeved on the surface of the screw 41, and the pressure plate 46 is positioned between the threaded ring 44 and the tweezers body 1.

[0034] In this implementation scheme: the threaded ring 44 can be squeezed by the pressure plate 46 and the tweezers body 1 to improve the overall stability.

[0035] Working principle: During adjustment, push the pressing ring 341 towards the side closest to the push block 33. The pressing ring 341 drives the slide rod 342 and the locking rod 343 to move, and the spring 345 is stressed. At this time, the locking rod 343 moves to the straight groove in the locking slot 346, losing its restraint on the limiting groove in the locking slot 346. The push block 33 drives the adjusting head 31 to move. After moving to a certain position, release the pressing ring 341. The spring 345 drives the pressing ring 341 and the locking rod 343 to reset. The locking rod 343 can then be locked into the limiting groove in the locking slot 346, thus enabling adjustment. After the holiday, the ceramic bearing is positioned, and then the ceramic bearing is picked up by the tweezers body 1 in conjunction with the tweezers head 2 and the adjusting head 31. The anti-slip pad 32 can improve the anti-slip effect. When it is necessary to hold the ceramic bearing for a long time and move it, the threaded ring 44 can be rotated in the screw 41 by the handle 45. Then the threaded ring 44 and the pressure plate 46 squeeze the tweezers body 1. The tweezers body 1 can drive the tweezers head 2 and the adjusting head 31 to hold the ceramic bearing. The threaded ring 44 and the screw 41 can lock the clamping state without the need for continuous manual force to clamp.
