Description

Technical Field

[0001] This utility model relates to the field of clamping technology, and in particular to a clamp that is easy to install. Background Technology

[0002] Existing fixtures perform fundamental fixing functions in various industry scenarios. In the machinery manufacturing field, manual screw clamps are used to fix small and medium-sized blanks, maintaining workpiece stability during lathe and milling machine processing; pneumatic clamping fixtures are used in automotive assembly lines, enabling rapid clamping and release of workpieces during the positioning and welding of engine blocks and chassis components; hydraulic fixtures are used in heavy machinery manufacturing, such as during the machining of large machine tool beds, providing stable clamping force to prevent workpiece vibration. In scenarios such as electronic product assembly and furniture production, these fixtures, by adjusting the clamping force, meet the fixing requirements of workpieces of different materials, serving as fundamental equipment to ensure the stability of production operations.

[0003] However, among existing clamps, manual clamps are laborious to adjust and inefficient; pneumatic clamps rely on air sources, have complex pipeline layouts, and are easily affected by pressure fluctuations; hydraulic clamps are bulky, have high maintenance costs, and oil leaks can pollute the environment. They also have poor versatility and are difficult to adapt to installation needs of multiple sizes and angles.

[0004] In the prior art, for example, a fixture with easy installation according to publication number CN222449305U includes a fixture platform. The fixture platform has through holes on both its left and right sides. Each of the two through holes contains a transmission block. Two transmission seats are fixedly connected to the bottom surface of the fixture platform. Drive motors are fixedly mounted on the left and right sides of each of the two transmission seats. Transmission screws are fixedly mounted on the output ends of each of the two sets of drive motors. Threaded rings are threaded onto the outer surfaces of both sets of transmission screws. Sliding blocks are fixedly connected to the outer surfaces of both sets of threaded rings, and the outer surfaces of the sliding blocks are slidably connected to the inner walls of the transmission seats. The sides of the two sets of sliding blocks that are close to each other are fixedly connected to the outer surfaces of the two transmission blocks. Positioning holes are provided on the sides of the two transmission blocks that are close to each other. This easy-to-install fixture achieves the effect of automatic clamping of mechanical parts, improving the installation and clamping speed of mechanical parts inside the fixture. However, this design also has certain drawbacks. This design requires the mounting plate to maintain the same direction as the fixing plate and remain fixed, requiring constant monitoring of the fixing plate's position, thus lacking flexibility. Furthermore, to adapt to different installation targets of varying sizes, this design requires repeated replacement of clamps of different specifications, making the process cumbersome.

[0005] Therefore, this application provides an easy-to-install clamp to solve the problems mentioned in the background art. Utility Model Content

[0006] The purpose of this utility model is to overcome the shortcomings of the existing technology by proposing a clamp that is easy to install, with a simple structure and convenient fixation.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] An easy-to-install clamp includes a mounting plate, a second limiting block fixedly disposed on one side of the mounting plate, a motor housing fixedly disposed on one side of the second limiting block, a threaded rod connected to the output end of the motor housing, sliders threadedly connected to the outer walls of both ends of the threaded rod, a main clamping plate fixedly disposed on one side of the two sliders, an extension plate slidably disposed on the inner walls of both ends of the two main clamping plates, a side clamping plate fixedly disposed on one end of the extension plate, and a first buffer pad fixedly disposed on one side of the side clamping plate.

[0009] Furthermore, a rotating shaft is fixedly installed at the lower center of the mounting plate, a fixing plate is rotatably installed on the outer wall of the rotating shaft, and four mounting blocks are evenly fixed on the outer wall of the fixing plate, with mounting screws threaded in the middle of the four mounting blocks.

[0010] Furthermore, a first limiting block is fixedly provided at one end of the extension plate.

[0011] Furthermore, a third limiting block is fixedly provided on one side of the mounting plate.

[0012] Furthermore, the mounting plate is provided with second tightening screws on both sides of its upper end.

[0013] Furthermore, the upper sides of the two main clamping plates are provided with first tightening screws.

[0014] Furthermore, a second buffer pad is fixedly provided on one side of each of the two main clamping plates.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model proposes an easy-to-install clamp. The mounting plate and the fixing plate are connected by a rotating shaft, allowing the mounting plate to rotate flexibly on the fixing plate, greatly improving installation adaptability. During installation, the mounting plate can be rotated according to the angle and position requirements of the object to be fixed, eliminating the need for repeated disassembly and adjustment of the overall position, thus reducing installation steps. The rotating structure is easy to operate and adapts to the installation angle requirements of different scenarios. Especially in situations with limited space or special object angles, it can quickly find the installation position and reduce installation difficulty.

[0017] 2. This utility model proposes an easy-to-install clamp, in which a main clamping plate and a side clamping plate cooperate. The spacing of the side clamping plates can be adjusted by an extension plate that moves within the main clamping plate, flexibly adapting to the installation needs of motors of different sizes. During installation, the distance between the main and side clamping plates can be quickly adjusted by sliding the extension plate according to the width of the motor, eliminating the need to replace the clamp and reducing the hassle of replacing parts. The extension plate moves smoothly and is positioned stably, ensuring that the motor does not wobble after clamping. This improves the versatility of the clamp and simplifies the installation process, making it particularly suitable for batch installation scenarios of multiple motor models, reducing operational difficulty and improving installation efficiency.

Detailed Implementation

[0025] 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.

[0026] Reference Figure 1 , Figure 4 One embodiment provided by this utility model:

[0027] An easy-to-install clamp includes a mounting plate 1. A second limiting block 14 is fixedly installed on one side of the mounting plate 1. A motor housing 13 is fixedly installed on one side of the second limiting block 14. A threaded rod 15 is connected to the output end of the motor housing 13. Slider 7s are threadedly connected to the outer walls of both ends of the threaded rod 15. A main clamping plate 8 is fixedly installed on one side of the two sliders 7. An extension plate 4 is slidably installed on the inner walls of both ends of the two main clamping plates 8. A side clamping plate 3 is fixedly installed on one end of the extension plate 4. A first buffer pad 2 is fixedly installed on one side of the side clamping plate 3.

[0028] Specifically, mounting plate 1 is the main support plate of the fixture; the second limiting block 14 restricts the sliding range of slider 7 to prevent it from disengaging from threaded rod 15; motor box 13 has a built-in DC geared motor that supports forward and reverse rotation control, providing power for the rotation of threaded rod 15; threaded rod 15 is made of 45# steel with heat treatment, and the threads at both ends are opposite in direction, so that when it rotates, it drives the two sliders 7 to move closer or further away synchronously; slider 7 connects threaded rod 15 and main clamping plate 8, transmitting power to realize the adjustment of the distance between main clamping plates 8; main clamping plate 8 is the main clamping component, which houses extension plate 4; extension plate 4 is made of aluminum alloy and is clearance-fitted with main clamping plate 8, and can slide axially along the inner wall of main clamping plate to extend the clamping range; side clamping plate 3 cooperates with main clamping plate 8 to clamp the target from the side, enhancing the fixation stability; first buffer pad 2 is made of nitrile rubber with diamond-shaped anti-slip texture on the surface, which contacts the workpiece surface to avoid damage to the motor during clamping, and at the same time increases friction to prevent loosening.

[0029] Reference Figure 2 , Figure 5 A rotating shaft 17 is fixedly installed at the lower middle of the mounting plate 1. A fixing plate 10 is rotatably installed on the outer wall of the rotating shaft 17. Four mounting blocks 9 are evenly fixed on the outer wall of the fixing plate 10. Mounting screws 11 are threaded in the middle of the four mounting blocks 9.

[0030] Specifically, the rotating shaft 17 is connected to the fixed plate 10 through a bearing, and its upper end is fixed to the mounting plate 1, so that the mounting plate 1 can rotate around the center of the rotating shaft 17 and flexibly adjust the clamping angle; the fixed plate 10 provides a fixed base for the fixture and is connected to the external structure through the mounting blocks 9; the four mounting blocks 9 are evenly distributed around the fixed plate 10, providing mounting positions for the M8 mounting screws 11. After the screws pass through the mounting blocks 9 and are screwed into the external structure, the fixed plate 10 can be firmly fixed to ensure the overall stability of the fixture.

[0031] Reference Figure 3 One end of the extension plate 4 is fixedly provided with a first limiting block 12.

[0032] Specifically, the first limiting block 12 is located at the end of the extension plate 4 away from the side clamping plate 3. When the extension plate 4 slides out from the main clamping plate 8, it can prevent it from completely detaching from the main clamping plate 8, preventing the extension plate 4 from falling and ensuring structural integrity and safety of use.

[0033] Reference Figure 4A third limiting block 16 is fixedly installed on one side of the mounting plate 1.

[0034] Specifically, the third limiting block 16 works in conjunction with the second limiting block 14 to further limit the sliding limit of the slider 7, preventing the slider 7 from failing to hold due to excessive movement and enhancing the stability of the equipment operation.

[0035] Reference Figure 5 The upper end of the mounting plate 1 is provided with second tightening screws 18 on both sides.

[0036] Specifically, after the second tightening screw 18 is tightened, it can press against the fixing plate 10. When the mounting plate 1 is rotated to a suitable angle, the second tightening screw 18 is tightened to lock the rotating shaft 17 through friction, preventing the mounting plate 1 from rotating randomly during the clamping process and ensuring the stability of the clamping angle.

[0037] Reference Figure 1 The two main clamping plates 8 have first tightening screws 5 threaded on both sides of their upper ends.

[0038] Specifically, after the first tightening screw 5 is tightened, it can press against the extension plate 4. When the extension plate 4 is adjusted to the required length, its position is fixed to prevent the extension plate 4 from sliding during the clamping process, which would cause the distance between the side clamping plates 3 to change, thus ensuring the stability of the clamping dimensions.

[0039] Reference Figure 1 A second buffer pad 6 is fixedly installed on one side of each of the two main clamping plates 8.

[0040] Specifically, the second buffer pad 6 is made of nitrile rubber with diamond-shaped anti-slip texture on the surface. It is located inside the main clamping plate 8 and works in conjunction with the first buffer pad 2 to contact the workpiece from the main and side directions simultaneously, further buffering the clamping force, avoiding damage to the workpiece surface, and increasing the friction of the contact surface to improve the clamping firmness.

[0041] Working Principle: In use, the fixing plate 10 is fixed to the base surface via the mounting block 9 using the mounting screw 11. The mounting plate 1 is rotated around the rotating shaft 17 to adjust to a suitable angle, and the second tightening screw 18 is tightened to lock the angle. The motor housing 13 drives the threaded rod 15 to rotate. Because the threads at both ends are reversed, the two sliders 7 and the main clamping plate 8 move closer or further away synchronously, initially adjusting the clamping width. According to the workpiece size, the extension plate 4 is pulled to make the side clamping plate 3 fit against the side of the workpiece, and the first tightening screw 5 is tightened to fix the extension plate 4. The second buffer pad 6 of the main clamping plate 8 and the first buffer pad 2 of the side clamping plate 3 contact the workpiece together, avoiding damage to the motor and increasing friction, realizing convenient installation and fixing of workpieces of multiple angles and sizes.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
