Description

Technical Field

[0001] The utility model relates to the technical field of clamping tooling, in particular to a high-efficiency tiger-type pressing plate with an elastic rebound structure. Background Art

[0002] Tiger clamps are commonly used in industrial production to secure materials. They are widely used in machining, assembly, and other fields. Their primary function is to clamp materials to ensure stability during processing. Traditional tiger clamps typically rely on springs to apply continuous pressure to the clamping area to ensure material stability during processing. However, this design has several drawbacks in practical applications. For example:

[0003] 1. Traditional tiger-style clamps often feature a spring structure located in the clamping area to provide continuous clamping force. While this design effectively secures the material, the clamp still requires manual adjustment to release the material when the screws are loosened. This increases operational complexity and time consumption, particularly during high-frequency loading and unloading operations, which can lead to decreased work efficiency.

[0004] 2. Because the spring continuously applies pressure during the clamping process, especially for fragile or delicate materials, it is easy to generate excessive clamping force, causing deformation or damage to the material. This is particularly prominent when processing high-precision workpieces, reducing the product qualification rate.

[0005] To mitigate these issues, several improvements have been proposed. For example, some designs employ a snap-in mechanism that uses a spring to automatically apply clamping force when the clamp is engaged. However, while this design simplifies some operational steps, it often presents difficulties in precisely controlling the clamping force, leading to over-clamping. This not only increases the risk of material damage but can also cause the clamp to become stuck and difficult to release, further increasing operational complexity and time costs.

[0006] Therefore, how to simplify the operating process and effectively protect materials, especially to maintain efficiency and safety in high-frequency loading and unloading operations, has become a technical problem to be solved by the present utility model. Utility Model Content

[0007] The technical problem solved by the present invention is to address the defects existing in the above-mentioned prior art and provide a high-efficiency tiger-type pressure plate with an elastic rebound structure to solve the problem proposed in the above-mentioned background technology of simplifying the operating process and effectively protecting materials, especially maintaining efficiency and safety in high-frequency loading and unloading operations.

[0008] In order to solve the above technical problems, the technical solutions adopted by the present invention are as follows:

[0009] A high-efficiency tiger-type pressure plate with an elastic rebound structure, comprising an aluminum alloy base, a U-shaped slider, a countersunk bolt, a spring, a stainless steel pressure plate, a cylindrical bolt and a slide nut. The aluminum alloy base is provided with a slide groove, and the U-shaped slider is slidably connected to the slide groove.

[0010] The U-shaped slider is in the shape of a bent rod, and the bent rod includes a rod sliding portion close to one end of the rod and close to the other end of the rod;

[0011] One end of the U-shaped slider is fixedly connected to the stainless steel pressing plate, and the stainless steel pressing plate is provided with a sliding hole that cooperates with the sliding of the rod body;

[0012] The cylindrical bolt passes through the sliding hole on the stainless steel pressure plate and is fixedly connected to the aluminum alloy base. The spring is sleeved on the cylindrical bolt, and the spring is located between the stainless steel pressure plate and the aluminum alloy base. The cylindrical bolt is connected to the stainless steel pressure plate in a sliding fit.

[0013] The countersunk bolt passes through the aluminum alloy base and cooperates with the slide nut to fix the tiger pressure plate to the processing platform;

[0014] The spring is used to provide rebound force when the cylindrical bolt is loosened, so that the U-shaped slider automatically moves along the slide direction, thereby moving the stainless steel pressure plate away from the clamping position to facilitate the removal of materials.

[0015] As a further solution of the present invention, one end of the spring abuts the stainless steel pressure plate, and the other end abuts the aluminum alloy base so that the rebound force provided by the spring causes the U-shaped slider to move along the sliding groove direction when the cylindrical bolt is loosened.

[0016] As a further solution of the present invention, the aluminum alloy base is made of 6061 aluminum alloy, and the stainless steel pressure plate is made of 304 stainless steel.

[0017] As a further solution of the present invention, the slide nut is fixedly connected to the aluminum alloy base, and the slide nut cooperates with the countersunk bolt to fix the tiger pressure plate on the processing platform.

[0018] As a further solution of the present invention, the U-shaped slider includes a U-shaped opening end, and the U-shaped slider includes a U-shaped opening end fixedly connected to the stainless steel pressure plate.

[0019] As a further solution of the present invention, the fixed connection is a fixed connection by bolt connection.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. The U-shaped slider forms a stable, integrated dual-rail structure, making the sliders slide more smoothly and steadily. Furthermore, the integrated structure links the sliders with the stainless steel pressure plate, ensuring synchronization and stability during the clamping operation. This design effectively avoids the instability issues associated with traditional structures, improving the equipment's operating efficiency and durability while providing a more reliable guarantee for precision machining of workpieces.

[0022] 2. Compared with the traditional design that usually places the spring in the clamping part to continuously provide pressure, the utility model sets the spring structure at the tail, which not only takes advantage of the tail space, but also allows the stainless steel pressure plate to automatically pop open under the action of the spring, realizing quick unlocking and material removal operations, greatly simplifying the use process, especially suitable for high-frequency loading and unloading operations, and improving work efficiency.

[0023] 3. Significantly improved material protection: Traditional clamping methods typically apply continuous and high pressure during material clamping, which can damage the material, especially when handling fragile or delicate materials. The tail spring rebound structure of the present invention uses optimized mechanical design to smoothly release the clamping force when loosening the screw, avoiding excessive compression of the material and significantly reducing the risk of material deformation or damage, thereby providing users with a safer operating experience.

[0024] 4. When the U-shaped slider forms a stable double-slide structure, it can complete the clamping and disassembly operations more quickly, improve the assembly efficiency and reduce the use cost.

In an embodiment of the present invention, a high-efficiency tiger-type pressure plate with an elastic rebound structure includes an aluminum alloy base 1, a U-shaped slider 2, a countersunk bolt 3, a spring 4, a stainless steel pressure plate 5, a cylindrical bolt 6, and a slide nut 7. The aluminum alloy base 1 is provided with a slide groove, the U-shaped slider is in the shape of a bent rod, and the bent rod shape includes a rod sliding portion 13 near one end of the rod shape and near the other end of the rod shape; the U-shaped slider 2 is slidably connected to the slide groove 9; one end of the U-shaped slider 2 is fixedly connected to the stainless steel pressure plate 5, and the stainless steel pressure plate 5 is provided with a sliding hole 10;

[0040] The cylindrical bolt 6 is fixedly connected with the aluminum alloy base 1 through the sliding hole on the stainless steel pressing plate 5, the spring 4 is sleeved on the cylindrical bolt 6, and the spring 4 is located between the stainless steel pressing plate 5 and the aluminum alloy base 1; the cylindrical bolt 6 is in sliding fit with the stainless steel pressing plate 5; the countersunk bolt 3 passes through the aluminum alloy base 1 and cooperates with the sliding groove nut 7, and is used for fixing the tiger type pressing plate to the machining platform;

[0041] The spring 4 is used for providing a rebound force when the cylindrical bolt 6 is loosened, so that the U-shaped sliding block 2 automatically moves in the sliding groove direction, so that the stainless steel pressing plate 5 is away from the clamping position, and the material is convenient to take out.

[0042] One end of the spring 4 abuts against the stainless steel pressing plate 5, and the other end abuts against the aluminum alloy base 1; when the cylindrical bolt 6 is loosened, the spring 4 provides a rebound force to make the U-shaped sliding block 2 move in the sliding groove direction. The end of the stainless steel pressing plate 5 is fixedly connected with the U-shaped sliding block 2 through the detachable connecting device, and the connecting device comprises the cylindrical bolt 6 in screw fit with the U-shaped sliding block 2, so that the stainless steel pressing plate 5 can be conveniently disassembled and maintained.

[0043] The aluminum alloy base 1 is made of 6061 aluminum alloy, which is used for supporting and fixing the U-shaped sliding block 2 and the stainless steel pressing plate 5, and the 6061 aluminum alloy has good mechanical properties and corrosion resistance.

[0044] The stainless steel pressing plate 5 is made of 304 stainless steel, which is used for clamping the material, and the 304 stainless steel has excellent durability and corrosion resistance, which ensures the overall stability and durability of the tiger type pressing plate. The sliding groove nut 7 is fixedly connected with the aluminum alloy base 1, the sliding groove nut 7 cooperates with the countersunk bolt 3, which is used for fixing the tiger type pressing plate on the machining platform, and adjusting the fastening degree of the tiger type pressing plate by adjusting the position of the countersunk bolt 3. The U-shaped sliding block 2 comprises a U-shaped open end, and the U-shaped sliding block 2 comprises a U-shaped open end 8 fixedly connected with the stainless steel pressing plate 5 in a screw connection manner.

[0045] As shown in Figure 1 , the U-shaped sliding block 2 is installed on the aluminum alloy base 1, then the U-shaped sliding block 2 is connected with the stainless steel pressing plate 5 by using a screw, and finally the spring 4 is connected with the cylindrical bolt 6, at this time the installation is basically completed, and then the countersunk bolt 3 is fixedly connected with the sliding groove nut 7 arranged on the machining platform through the aluminum alloy base 1, which is used for connecting the tiger type pressing plate to the machining platform.

[0046] As shown in Figure 4 , at this time the cylindrical bolt 6 has not been screwed, and the tiger type pressing plate is in a relaxed state. By screwing the cylindrical bolt 6, the spring 4 is compressed, and the U-shaped sliding block 2 is pushed to stretch to press the material, as shown in Figure 5 , and when it is retracted, as shown in Figure 6 , at this time it is the isometric view of the U-shaped sliding block 2 when it is stretched, and it can be obviously seen that the sliding block is stretched. Figure 7 As shown, this is the state when the tiger clamp is ready to clamp the material. First, the tiger clamp is fixed to the processing plane 11. The tiger clamp fixes the workpiece 12 as the material by clamping both sides of the workpiece 12. Figure 8 Therefore, place one side of the material close to the tiger press plate, such as Figure 9 As shown, the other side 6 is then tightened to clamp the material and tighten both sides until the material is fixed. After processing is completed, the worker only needs to loosen the bolt 4. At this time, the spring 4 automatically provides a rebound force, causing the stainless steel pressure plate 5 to quickly spring open, thus easily releasing the metal sheet.

[0047] Example 1:

[0048] In a large machining facility, workpieces of varying sizes and materials often need to be clamped and secured for precision machining. These workpieces include sheet metal, plastics, and other fragile materials. Due to the frequent machining operations and the demanding clamping requirements, traditional tiger-style clamps present numerous challenges.

[0049] Traditional Tiger-style clamps rely on a spring structure at the clamping point to provide continuous clamping force. While this secures the workpiece, the user must manually adjust the clamp to release the workpiece when loosening the screws. This process is time-consuming and complex, especially during high-frequency loading and unloading operations. It not only reduces work efficiency but can also lead to workpiece damage due to excessive clamping force, a particularly serious problem when machining precision parts or fragile materials.

[0050] In order to solve this problem, the present invention has made innovative improvements based on the traditional tiger-type pressure plate. By introducing a spring 4 rebound structure at the tail, the operating process is simplified and the workpiece protection effect is improved.

[0051] In practice, the tiger-style pressure plate of the present invention cleverly integrates a spring 4 rebound structure at the rear end. When the user loosens a screw, the spring 4 immediately acts on the stainless steel pressure plate 5, causing it to automatically spring open, eliminating the need for manual adjustment of the pressure plate's position to quickly release the workpiece. This design greatly simplifies the operational process and is particularly suitable for production lines that require frequent replacement and processing of different workpieces. In this implementation scenario, the worker simply loosens the screw, and the stainless steel pressure plate 5 automatically springs open, allowing the workpiece to be quickly removed, significantly improving loading and unloading efficiency.

[0052] Furthermore, because the spring 4 rebound structure applies force only when the screw is loosened, it avoids workpiece deformation or damage caused by continuous pressure in traditional clamping methods. This is particularly critical when machining fragile materials or parts requiring high precision. During one machining process, the tiger-type clamping plate of the present invention was used to secure a batch of plastic parts. Due to their poor flexibility, traditional clamping methods often cause indentations or deformation on the part surface. However, the design of the present invention successfully avoids these problems by smoothly releasing the clamping force, ensuring part integrity and machining accuracy.

[0053] Through this implementation, the tiger-style clamping plate of the present invention not only significantly improves operational efficiency and reduces workpiece clamping time, but also effectively protects the workpiece, especially fragile and delicate workpieces, achieving unexpected technical results and significant progress. The application of this technology enables production lines to operate with higher efficiency and lower wear rates, meeting the demand for efficient and safe clamping devices in modern industrial production.

[0054] Example 2:

[0055] In a certain metal processing company, various metal plates need to be clamped frequently during the production process in order to perform fine operations such as cutting and grinding. The company once used traditional all-steel tiger-type pressure plates, but found that this type of pressure plate had multiple problems. First of all, all-steel tiger-type pressure plates are expensive and can easily damage the surface of the metal plates during the clamping process, especially when processing thinner aluminum or copper plates, which often leave obvious indentations. In addition, since traditional tiger-type pressure plates lack a rebound structure, workers need to manually adjust the screws and the position of the pressure plate when loosening the pressure plate, which not only increases the operation time, but also easily causes worker fatigue during repeated operations, affecting production efficiency.

[0056] To address these issues, the company introduced the present invention's economical tiger-style clamp with a spring-back structure. This clamp utilizes a combination of aluminum alloy and stainless steel, significantly reducing costs and minimizing damage to the metal sheet during the clamping process. The aluminum alloy's moderate material quality makes it particularly suitable for contact with the material, while the stainless steel used for the stainless steel clamp 5 and screw fasteners ensures the clamp's stability and durability.

[0057] During operation, the worker first installs the slider onto the aluminum alloy base 1, then secures the stainless steel pressure plate 5 to the slider with bolts. A spring 4 is positioned over the bolts and between the stainless steel pressure plate 5 and the aluminum alloy base 1. To clamp the sheet metal, the worker tightens the bolts, compressing the spring 4 and pushing the slider and stainless steel pressure plate 5 to tightly clamp the sheet metal. Once the process is complete, the worker simply loosens the bolts, and the spring 4 automatically provides a rebound force, causing the stainless steel pressure plate 5 to quickly spring open, releasing the sheet metal easily.

[0058] By using the tiger-style pressure plate of the present invention, the company has not only significantly improved production efficiency and reduced operator labor intensity, but also effectively protected the surface quality of the workpiece. The stability and durability of the pressure plate have been fully verified during repeated use. The automatic rebound function of the pressure plate greatly simplifies the operation process during frequent clamping and release operations, ensuring an efficient and precise production rhythm.

Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations that come within the meaning and range of equivalents of the claims be embraced within the present invention.
