Description

Technical Field

[0001] This invention relates to a magnetic lifting clamp for processing chemical pump housings, belonging to the field of lifting clamp technology. Background Technology

[0002] A fixture is a device used in mechanical manufacturing to fix a workpiece in the correct position for operation or inspection. Also known as a clamp, broadly speaking, any device used to quickly, conveniently, and safely install a workpiece in any step of the manufacturing process can be called a fixture. A fixture typically consists of positioning elements (to determine the correct position of the workpiece in the fixture), clamping devices, tool setting and guiding elements (to determine the relative position of the tool and the workpiece or guide the direction of the tool), indexing devices (to enable the workpiece to complete machining at several stations in one setup; there are two types: rotary indexing devices and linear indexing devices), connecting elements, and the fixture body (fixture base). There are many types of fixtures, including lifting fixtures, which are required when machining the casing of a chemical pump.

[0003] Chinese Patent Publication No. CN 221876337 U discloses a lifting clamp, including a connecting plate. A lifting ring is located at the top of the connecting plate, and a lifting body is located at the bottom of the connecting plate. The lifting body has a trapezoidal structure and a sliding groove at its bottom. A limiting groove is formed in the middle of the sliding groove, and a moving block is slidably disposed within the sliding groove. A clamping assembly is located at the bottom of the moving block. The clamping assembly includes a first clamping ring and a second clamping ring. One end of each clamping ring is hinged to the bottom of the moving block, and the other end of each clamping ring is provided with a connecting fixing plate. The connecting fixing plate has a locking through hole. The first and second clamping rings form a ring and are fixed by locking bolts and nuts. This invention relates to the field of lifting technology, specifically providing a lifting clamp.

[0004] However, when using the above technology, the clamping position and the spacing between the clamps need to be adjusted by the operator, which is a cumbersome process. Each time the casing of a chemical pump of different sizes is clamped, the operator needs to adjust the clamps himself, which is inconvenient for the operator to use.

[0005] Chinese Patent Publication No. CN217756520U discloses a lifting clamp, relating to the field of lifting fixtures. The lifting clamp includes a guide rail, a lifting connector, and two fixing components. Each fixing component includes a sliding block, a cylinder, and two clamping plates. The lifting connector is installed in the middle of the guide rail. The sliding block is slidably mounted on the guide rail. The cylinder is installed at the lower end of the sliding block. The two clamping plates are respectively connected to the output ends on both sides of the cylinder. The clamping plates are vertically arranged. The cylinder is a pneumatic cylinder. Rubber pads are provided on the inner side of the clamping plates. The two fixing components of this invention can slide on the guide rail to accommodate and clamp finned heat exchangers of different sizes. Then, the cylinder brings the two clamping plates together to fix the finned heat exchanger. The rubber pads on the clamping plates prevent the fins on the finned heat exchanger from tilting or deforming during clamping. This invention has a simple structure and reasonable design, facilitating the movement of heavy finned heat exchangers.

[0006] However, the above-mentioned technology uses a planar clamp design, which may result in a small contact area with the material when clamping curved materials. In actual use, this may lead to the curved material falling accidentally. In addition, the above-mentioned device relies solely on the clamping force of the clamp to work on the material, which may cause deformation of thin-walled or easily deformable workpieces, resulting in relatively poor flexibility and adaptability.

[0007] To address this, a magnetic lifting clamp for machining chemical pump housings is proposed. Summary of the Invention

[0008] In view of this, the present invention provides a magnetic lifting fixture for processing chemical pump housings, so as to solve or alleviate the technical problems existing in the prior art, and at least provide a beneficial option.

[0009] The technical solution of the present invention is implemented as follows: A magnetic lifting clamp for processing chemical pump housings includes a lifting base. Mounting rings are fixedly installed on both the left and right sides of the top of the lifting base. Lifting rings are fitted onto the surfaces of both mounting rings. Connecting steel cables are fixedly installed onto the surfaces of both lifting rings. The other ends of both connecting steel cables are fixedly connected to an external winding device. An adjustment assembly is provided on the surface of the lifting base. The adjustment assembly includes a drive motor, which is fixedly installed on the right side of the lifting base. A bidirectional screw is fixedly connected to the output end of the drive motor. Screw blocks are fixedly installed on both the left and right sides of the surface of the bidirectional screw. Mounting blocks are fixedly installed on the front and rear sides of both screw blocks. A bearing block is fixedly installed on the other end of each of the four mounting blocks. Mounting rods are fixedly installed on the surfaces of each of the four bearing blocks.

[0010] The surface of the mounting rod is provided with a clamping assembly, which includes a horizontal plate. Two horizontal plates are fixedly installed on the other end of the four mounting rods. The front and rear sides of the surface of the two horizontal plates are provided with slots. A hydraulic telescopic cylinder is fixedly installed on the top of the horizontal plate. A lifting block is fixedly installed on the top of the hydraulic telescopic cylinder. Movable rods are movably connected to the front and rear sides of the surface of the lifting block. A moving block is movably connected to the other end of the movable rod. A fixed rod is fixedly installed at the bottom of the moving block. A clamping plate is fixedly installed at the other end of the fixed rod. Electromagnets are fixedly installed on the surface of the clamping plate.

[0011] More preferably, the thread directions on the left and right sides of the bidirectional screw surface are opposite, and the thread pitch on the left and right sides of the bidirectional screw surface is consistent with each other.

[0012] More preferably, each of the four mounting rods has a reinforcing rib on its surface, and the reinforcing rib is welded to the surface of the mounting rod.

[0013] More preferably, the lifting base has movable slots on both the front and rear sides, and the mounting rod passes through the inner cavity of the movable slot and extends to the outer side of the lifting base.

[0014] More preferably, each of the lifting bases has a guide rail fixedly installed in its inner cavity, and the four bearing blocks are slidably connected to the surfaces of two of the guide rails.

[0015] More preferably, a limiting plate is fixedly installed in the inner cavity of the hoisting base, and both screw blocks are slidably connected to the surface of the limiting plate.

[0016] More preferably, a guide rod is fixedly installed in the inner cavity of the slot, and the moving block is slidably connected to the surface of the guide rod.

[0017] More preferably, a limit frame is fixedly installed on the top of the horizontal plate, and the lifting block is slidably connected to the surface of the limit frame.

[0018] More preferably, a wireless switch for the motor is fixedly installed on the right side of the hoisting base, and the output terminal of the wireless switch is electrically connected to the input terminal of the drive motor.

[0019] More preferably, an electromagnetic wireless switch is fixedly installed on the left side of the hoisting base, and the output terminal of the electromagnetic wireless switch is electrically connected to the input terminal of the electromagnet.

[0020] The embodiments of the present invention have the following advantages due to the adoption of the above technical solutions:

[0021] I. This invention, through the setting of an adjustment component and the output of a drive motor, enables a bidirectional screw to move the screw block and the mounting rod. The movement of the mounting rod synchronously moves the clamping component, allowing the clamping component to clamp and fix chemical pump housings of different lengths. This improves the flexibility and convenience of clamping the chemical pump housing, making it easier for operators to use. By setting the clamping component and extending the hydraulic telescopic cylinder, the lifting block and the movable rod can cooperate, allowing the clamping plate to move inward for clamping. The electromagnet can electromagnetically attract the chemical pump housing, thus achieving clamping and fixing of chemical pump housings of different widths. Furthermore, due to the shape characteristics of the clamping plate, stability is ensured when clamping chemical pump housings with curved surfaces. The electromagnet further enhances the firmness of the chemical pump housing inside the clamping plate, avoiding situations where excessive force is required to fully clamp and lift the chemical pump housing.

[0022] Second, this invention provides support for the mounting rod by setting reinforcing ribs, preventing deformation after prolonged use. The moving groove guides the movement of the mounting rod, ensuring directional accuracy. The guide rail guides the movement of the load-bearing block, preventing changes in direction. The limiting plate limits the movement of the screw block, preventing it from rotating synchronously with the bidirectional screw. The guide rod guides the movement of the moving block, preventing directional deviation. The limiting frame limits the movement of the lifting block, ensuring directional accuracy.

[0034] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of the invention. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0035] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0036] Example 1

[0037] like Figure 1-8As shown, this embodiment of the invention provides a magnetic lifting clamp for processing chemical pump housings, including a lifting base 1. Mounting rings 4 are fixedly installed on both the left and right sides of the top of the lifting base 1. Lifting rings 5 ​​are fitted onto the surface of each mounting ring 4, and connecting steel cables 6 are fixedly installed on the surface of each lifting ring 5. The other ends of the connecting steel cables 6 are fixedly connected to an external winding device. An adjustment assembly 2 is provided on the surface of the lifting base 1. The adjustment assembly 2 includes a drive motor 201, which is fixedly installed on the right side of the lifting base 1. A bidirectional screw 20 is fixedly connected to the output end of the drive motor 201. 2. Screw blocks 203 are fixedly installed on both the left and right sides of the surface of the bidirectional screw 202. Mounting blocks 204 are fixedly installed on both the front and rear sides of the two screw blocks 203. Bearing blocks 205 are fixedly installed on the other end of the four mounting blocks 204. Mounting rods 206 are fixedly installed on the surface of the four bearing blocks 205. The thread directions on the left and right sides of the surface of the bidirectional screw 202 are opposite, and the thread spacing on the left and right sides of the surface of the bidirectional screw 202 is consistent with each other. A motor wireless switch 7 is fixedly installed on the right side of the lifting base 1. The output end of the motor wireless switch 7 is electrically connected to the input end of the drive motor 201.

[0038] The surface of the mounting rod 206 is provided with a clamping assembly 3, which includes a horizontal plate 301. Two horizontal plates 301 are fixedly installed on the other end of the four mounting rods 206. The front and rear sides of the surface of the two horizontal plates 301 are provided with slots 302. A hydraulic telescopic cylinder 303 is fixedly installed on the top of the horizontal plate 301. A lifting block 304 is fixedly installed on the top of the hydraulic telescopic cylinder 303. Movable rods 305 are movably connected to the front and rear sides of the surface of the lifting block 304. A moving block 306 is movably connected to the other end of the moving rod 305. A fixing rod 307 is fixedly installed at the bottom of the moving block 306. A clamping plate 308 is fixedly installed at the other end of the fixing rod 307. Electromagnets 309 are fixedly installed on the surface of the clamping plate 308. An electromagnetic wireless switch 8 is fixedly installed on the left side of the hoisting base 1. The output end of the electromagnetic wireless switch 8 is electrically connected to the input end of the electromagnet 309.

[0039] By setting the adjustment component 2, the output of the drive motor 201 allows the bidirectional screw 202 to move the screw block 203 and the mounting rod 206. When the mounting rod 206 moves, it simultaneously moves the clamping component 3, enabling the clamping component 3 to clamp and fix chemical pump housings of different lengths. This improves the flexibility and convenience of clamping the chemical pump housing, making it easier for operators to use. Furthermore, by setting the clamping component 3 and extending the hydraulic telescopic cylinder 303, the lifting block 304 can engage with the movable rod 305. This allows the clamping plate 308 to move inwards for clamping, while the electromagnet 309 can electromagnetically attract the chemical pump housing, thereby achieving clamping and fixing of chemical pump housings of different widths. At the same time, due to the shape characteristics of the clamping plate 308, the stability of clamping the curved surface of the chemical pump housing can be ensured. In addition, the electromagnet 309 can further improve the firmness of the chemical pump housing inside the clamping plate 308, avoiding the situation where the clamping plate 308 needs to use excessive force to fully clamp and lift the chemical pump housing.

[0040] Example 2

[0041] like Figure 2-8 As shown, in one embodiment, the surfaces of the four mounting rods 206 are provided with reinforcing ribs 207, which are welded to the surfaces of the mounting rods 206. The front and rear sides of the lifting base 1 are provided with moving slots 208. The mounting rods 206 pass through the inner cavity of the moving slots 208 and extend to the outer side of the lifting base 1. The inner cavity of the lifting base 1 is fixedly installed with guide rails 209. The four bearing blocks 205 are slidably connected to the surfaces of the two guide rails 209. The inner cavity of the lifting base 1 is fixedly installed with a limiting plate 210. The two screw blocks 203 are slidably connected to the surface of the limiting plate 210. The inner cavity of the slot 302 is fixedly installed with a guide rod 310. The moving block 306 is slidably connected to the surface of the guide rod 310. The top of the horizontal plate 301 is fixedly installed with a limiting frame 311. The lifting block 304 is slidably connected to the surface of the limiting frame 311.

[0042] By setting the reinforcing rib 207, the mounting rod 206 can be supported, preventing its shape from deforming after long-term use. By setting the moving groove 208, the movement of the mounting rod 206 can be guided, ensuring the accuracy of its movement direction. By setting the guide slide rail 209, the movement of the bearing block 205 can be guided, preventing its movement direction from changing. By setting the limiting plate 210, the movement of the screw block 203 can be limited, preventing the screw block 203 from rotating synchronously with the bidirectional screw 202. By setting the guide rod 310, the movement of the moving block 306 can be guided, preventing its movement direction from deviating. By setting the limiting frame 311, the movement of the lifting block 304 can be limited, ensuring the accuracy of its movement direction.

[0043] In operation, when hoisting and clamping the chemical pump housing, the bidirectional screw 202 rotates based on the length of the chemical pump housing, driven by the output of the drive motor 201. During this rotation, the bidirectional screw 202 drives the screw block 203 to move. The movement of the screw block 203 synchronously moves the mounting block 204 and the bearing block 205. As the bearing block 205 moves, the mounting rod 206 causes the clamping assembly 3 to shift, ensuring that the positions of the clamping assemblies 3 on both sides match the length of the chemical pump housing. After moving the chemical pump housing to the inside of the clamping plate 308, the hydraulic telescopic cylinder 303 extends. 3. The lifting block 304 is moved upward, and the lifting block 304 cooperates with the movable rod 305. At this time, the movable rod 305 will pull the moving block 306 and the fixed rod 307 to move downward and inward in sync. When the fixed rod 307 moves inward, it will drive the clamping plate 308 to move inward. The clamping plate 308 clamps and fixes the chemical pump housing. At the same time, the electromagnet 309 is controlled to magnetically attract, so as to fix the chemical pump housing again. Then, through the external winding equipment, the connecting steel cable 6 is wound up, so that the connecting steel cable 6 drives the lifting ring 5, the mounting ring 4, the lifting seat 1 and the chemical pump housing to move upward in sync, so as to realize the overall lifting work of the chemical pump housing.

[0044] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in the present invention, and these should all be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
