Description

Technical Field

[0001] This utility model relates to the field of permanent magnet chuck technology, specifically a highly sealed and waterproof permanent magnet chuck. Background Technology

[0002] A permanent magnet chuck is a tool that uses the magnetic force generated by a permanent magnet to attract workpieces. It does not require an external power source and can stably attract various magnetic materials by relying on the inherent magnetism of the permanent magnet. This type of chuck has a simple structure and is easy to operate. It is widely used in machining, mold making, workpiece handling and other fields. With its characteristic of maintaining the attraction force without power, it not only reduces energy consumption, but also avoids the risk of workpiece falling off due to power failure.

[0003] For example, patent CN212420509U discloses a novel permanent magnet chuck, including an annular permanent magnet chuck with a circular permanent magnet chuck nested inside its inner cavity. A support mechanism is fixedly installed between the annular and circular permanent magnet chucks. The support mechanism includes a movable groove inside the annular permanent magnet chuck, and a connecting block fixedly installed on the circumferential outer wall of the circular permanent magnet chuck. The connecting block has a sliding groove inside, and a fixed sliding rod is fixedly installed in the inner cavity of the movable groove. The fixed sliding rod is located in the corresponding sliding groove cavity, and the connecting block is slidably connected to the circumferential outer wall of the corresponding fixed sliding rod. However, the existing device lacks a waterproof structure. When the permanent magnet chuck is used in a humid workshop environment or for outdoor operations in coastal areas, water or moisture can easily penetrate the chuck. Once the permanent magnet comes into contact with water, it will quickly rust and corrode, causing a significant weakening of the magnetic force, a decrease in adsorption capacity, and an inability to stably grip workpieces, seriously affecting production efficiency and operational safety.

[0004] Therefore, in order to solve this problem, we propose a highly sealed and waterproof permanent magnet chuck. Utility Model Content

[0005] The purpose of this invention is to provide a highly sealed and waterproof permanent magnet chuck to solve the problem mentioned in the background art that, without a waterproof structure, water or moisture can easily penetrate the chuck when it is used in a humid workshop environment or for outdoor operations in coastal areas. Once the permanent magnet comes into contact with water, it will quickly rust and corrode, resulting in a significant weakening of the magnetic force, a decrease in adsorption capacity, and an inability to stably grip workpieces, which seriously affects production efficiency and operational safety.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a highly sealed and waterproof permanent magnet chuck, comprising a housing and a base plate disposed at the bottom of the housing, a U-shaped rod being connected through the top of the housing, a second dovetail groove being provided on both sides of the inner wall of the housing, a fixing block being fixedly connected to both ends of the bottom of the U-shaped rod, a first rack being fixedly connected to the bottom of the fixing block, a first dovetail block being fixedly connected to one side of the outer wall of the first rack, a U-shaped frame being fixedly connected to one side of the top of the U-shaped rod of the inner wall of the housing, a gear being rotatably connected to the U-shaped frame, a second dovetail block being movably connected in the second dovetail groove, a second rack being fixedly connected to the outer wall of the second dovetail block, a pressing rod being fixedly connected to the bottom of the second rack, an air bladder being fixedly connected to the bottom of the inner wall of the housing, and a liquid bladder being fixedly connected to the top of the air bladder.

[0007] Furthermore, both ends of the U-shaped rod are fixedly connected to limiters, a spring is movably sleeved on the U-shaped rod, and a pull ring is fixedly connected to the middle of the top surface of the U-shaped rod.

[0008] Furthermore, side plates are fixedly connected to both sides of the top of the base plate, and a first dovetail groove is provided on the side of the side plate near the first rack, and the first dovetail block is movably connected within the first dovetail groove.

[0009] Furthermore, a magnet is provided on the top of the base plate, and a partition is fitted on the top of the magnet. Both ends of the bottom of the partition are fixedly connected with locking blocks, and the outer walls on both sides of the partition are sealed to the inner wall of the shell.

[0010] Furthermore, a rubber protrusion is fixedly connected to the bottom of the housing, and a sealing groove is fixedly connected to the top of the base plate, with the rubber protrusion engaging within the sealing groove.

[0011] Furthermore, both ends of the outer walls on both sides of the housing are fixedly connected to support blocks, and bolts are movably connected to the support blocks. The housing and the base plate are fixedly connected by bolts.

[0012] Furthermore, the top of the spring is fixedly connected to the top of the inner wall of the housing, and the bottom of the spring is fixedly connected to the top of the fixing block.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the highly sealed and waterproof permanent magnet chuck adopts a novel structural design, the specific details of which are as follows:

[0014] (1) This high-sealing and waterproof permanent magnet chuck, through the setting of air bladder and liquid bladder, when the device is put into operation, the pressing rods located at both ends inside the shell will press down on the air bladder and liquid bladder simultaneously. Under the action of the pressing force, the air bladder will undergo elastic deformation, thereby fully fitting into the gap between the shell and the base plate. This fitting effect is like building a tight waterproof barrier inside the chuck, which can effectively block the intrusion of water or water vapor, providing good protection for the magnet, keeping it in a dry environment, avoiding the risk of rust and corrosion, ensuring the long-term stability of the magnetic force, and the stable adsorption force can ensure the reliable fixation of the workpiece, reducing the workpiece displacement and falling problems caused by poor adsorption, thereby significantly improving production efficiency.

[0015] (2) This high-sealing and waterproof permanent magnet chuck utilizes multiple partitions to seal the magnet at equal intervals. At the structural level, the magnet is precisely installed and positioned. When the device is in operation, it can effectively prevent the magnet from shaking inside the chuck, ensuring that the magnet is always in a stable position and providing a stable adsorption base for the chuck. In terms of protection, the partitions play an important role in moisture prevention. Due to the presence of the partitions, the magnet is divided into multiple independent areas, avoiding large areas of the magnet being directly exposed to environments where moisture may exist. In this way, even under humid working conditions, the risk of the magnet getting damp and rusting can be minimized, thereby maintaining the magnetic effect of the magnet and ensuring that the adsorption performance of the chuck is stable and durable.

[0016] Furthermore, by carefully designed rubber protrusions at the bottom of the housing, it can be tightly engaged in the corresponding sealing groove at the top of the base plate. The rubber protrusions have good elasticity and deformation capacity, and can fully fill the gap during the engagement process, effectively preventing the intrusion of external impurities such as water and dust, thus achieving an excellent sealing effect. Then, by using the support blocks set at both ends of the outer walls on both sides of the housing, and by bolts, the housing and the base plate are firmly fixed together. The tightening action of the bolts provides strong tensile force, ensuring that the housing and the base plate fit tightly together, enhancing the connection strength of the structure, and effectively resisting external impacts and vibrations, thus preventing loosening or separation during use.

[0024] 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.

[0025] This utility model provides the following technical solution: a highly sealed and waterproof permanent magnet chuck.

[0026] Example 1: A highly sealed and waterproof permanent magnet chuck, through the arrangement of components such as a first rack 121, a second rack 141, and a gear 131, when the device is in operation, the pressing rods 15 at both ends inside the housing 1 press the air bladder 19 and the liquid bladder 191, so that the air bladder 19 fully fits the gap between the housing 1 and the base plate 2, providing waterproof protection for the magnet 17. Figure 1 - Figure 5As shown, a highly sealed and waterproof permanent magnet chuck includes a housing 1 and a base plate 2 disposed at the bottom of the housing 1. A U-shaped rod 11 is connected through the top of the housing 1. Second dovetail grooves 114 are provided on both sides of the inner wall of the housing 1. Fixing blocks 12 are fixedly connected to both ends of the bottom of the U-shaped rod 11. A first rack 121 is fixedly connected to the bottom of the fixing block 12. A first dovetail block 122 is fixedly connected to one side of the outer wall of the first rack 121. A U-shaped frame 13 is fixedly connected to one side of the top of the U-shaped rod 11 on the inner wall of the housing 1. A gear 131 is rotatably connected to the U-shaped frame 13. A second dovetail block 14 is movably connected in the second dovetail groove 114. A second rack 141 is fixedly connected to the outer wall of the second dovetail block 14. A pressing rod 15 is fixedly connected to the bottom of the second rack 141. An air bladder 19 is fixedly connected to the bottom of the inner wall of the housing 1. A liquid bladder 191 is fixedly connected to the top of the air bladder 19. Limiting bodies 111 are fixedly connected to both ends of the U-shaped rod 11. A spring 112 is movably sleeved on the U-shaped rod 11. A pull ring 113 is fixedly connected to the middle of the top surface of the U-shaped rod 11. Side plates 16 are fixedly connected to both sides of the top of the bottom plate 2. A first dovetail groove 161 is opened on the side of the side plate 16 near the first rack 121. A first dovetail block 122 is movably connected in the first dovetail groove 161. The top of the spring 112 is fixedly connected to the top of the inner wall of the housing 1, and the bottom of the spring 112 is fixedly connected to the top of the fixing block 12.

[0027] When the permanent magnet chuck needs to be operated, pull the pull ring 113 on the U-shaped rod 11. The U-shaped rod 11 moves upward, causing the bottom fixing block 12 to rise as well. The first rack 121 at the bottom of the fixing block 12 rises accordingly. Since the first dovetail block 122 on one side of the outer wall of the first rack 121 is movably connected in the first dovetail groove 161 of the side plate 16, the first rack 121 moves smoothly. During the upward movement of the first rack 121, it meshes with the gear 131 rotatably connected to the U-shaped frame 13, driving the gear... As wheel 131 rotates, gear 131 rotates and meshes with the second rack 141 on the outer wall of the second dovetail block 14, causing the second rack 141 to move downwards. This, in turn, drives the bottom pressing rod 15 to move downwards. The pressing rod 15 presses down on the air bladder 19 and the liquid bladder 191. The air bladder 19 deforms after being squeezed, fully filling and fitting the gap between the shell 1 and the bottom plate 2, forming a waterproof barrier to prevent water or moisture from entering the suction cup and contacting the magnet 17, thus achieving waterproof protection for the magnet 17.

[0028] Example 2: Unlike Example 1, multiple partitions 18 are used to seal the magnet 17 at equal intervals, while also limiting the installation of the magnet 17 to prevent large-area moisture absorption and rusting, which would affect the magnetic effect. Figure 6As shown, a magnet 17 is provided on the top of the base plate 2, and a partition 18 is sleeved on the top of the magnet 17. Both ends of the bottom of the partition 18 are fixedly connected to the locking blocks 181, and the outer walls on both sides of the partition 18 are sealed to the inner wall of the housing 1. A rubber protrusion 115 is fixedly connected to the bottom of the housing 1, and a sealing groove 21 is fixedly connected to the top of the base plate 2. The rubber protrusion 115 is locked in the sealing groove 21. Both ends of the outer walls on both sides of the housing 1 are fixedly connected to the support blocks 3, and bolts 31 are movably connected to the support blocks 3. The housing 1 and the base plate 2 are fixedly connected by bolts 31.

[0029] Multiple partitions 18 are arranged in an orderly manner on the top of the magnet 17, and the locking blocks 181 at both ends of the bottom are precisely embedded in the corresponding positions to securely limit the installation of the magnet 17, preventing the magnet 17 from shaking randomly inside the suction cup and ensuring the stability of the internal structure of the suction cup. At the same time, the outer walls on both sides of the partitions 18 are sealed to the inner wall of the shell 1. The partitions 18 divide the magnet 17 into multiple relatively independent areas. In a humid environment, this partition structure greatly reduces the area of ​​the magnet 17 that is affected by moisture and rust, effectively delaying the magnetic attenuation caused by the oxidation of the magnet 17 due to moisture. By maintaining the magnetic stability of the magnet 17, the adsorption performance of the permanent magnet suction cup is stabilized, and it can reliably adsorb workpieces under any working conditions, ensuring the smooth operation of production.

[0030] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
