Description

Technical Field

[0001] The utility model relates to the technical field of clamps, in particular to a bench clamp which is easy to install and disassemble. Background Art

[0002] A bench vise that is easy to install and disassemble combines a quick clamping device and a quick changing device, is made of special chromium-molybdenum alloy steel, and has the function of adjustable clamping force. The optimized design makes it easy to install and disassemble, improves operating efficiency; the material optimization enhances wear resistance and stability; the adjustable clamping force is suitable for different workpiece requirements. The existing bench vise that is easy to disassemble (publication number: CN219542866U) has the following disadvantages and needs further improvement.

[0003] 1. Traditional equipment takes a long time to install and disassemble the workpiece, and needs to be fixed by screws or manual operation, which consumes more manpower and time. Moreover, when the workpiece is frequently replaced, this inefficient operation will lead to reduced production efficiency, increasing the downtime and cost of the production line. In addition, since the operation requires certain technical requirements, unskilled operators may cause loose installation, affecting the accuracy and quality of workpiece processing. Therefore, there is an urgent need for a bench vise that is easy to install and disassemble.

[0004] 2. Traditional equipment uses ordinary steel or other materials to manufacture fixtures, and these materials have poor wear resistance and corrosion resistance. After long-term use, the equipment is prone to problems such as surface wear and rust on the fixture, which shortens the service life of the fixture and reduces its stability. Due to material limitations, it is difficult for traditional fixtures to guarantee the clamping force and precision of the workpiece, and the clamping force may be loose or uneven, affecting the quality and precision of workpiece processing. Therefore, a bench vise with optimized material is urgently needed.

[0005] 3. Traditional equipment applies too much clamping force, causing deformation or damage; and for some heavy workpieces, it may not provide sufficient clamping force, resulting in unstable workpieces. The equipment cannot adjust the clamping force precisely according to the requirements of the workpiece, resulting in unstable position or slight deviation of the workpiece during processing, thus affecting the processing accuracy and product quality. Due to the inability to flexibly adjust the clamping force, the equipment requires more time and effort to handle different types of workpieces, resulting in reduced production efficiency. Therefore, a bench vise with adjustable clamping force is urgently needed. Utility Model Content

[0006] The main purpose of the utility model is to provide a bench vise clamp which is easy to install and disassemble, and can effectively solve the problems in the background technology.

[0007] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: there is a bench vise clamp which is easy to install and disassemble, a positioning hole is installed inside the main body, a clamp is installed above the main body, a pneumatic device is installed above the clamp, a chrome-molybdenum alloy steel sandwich base is installed above the clamp, a chrome-molybdenum alloy steel clamping block is installed above the clamp, a transmission shaft is installed above the clamp, a hydraulic adjustment block is installed above the clamp, a driven shaft is installed above the clamp, a quick clamping device is installed on one side of the driven shaft, and a quick mold changing device is installed on one side of the driven shaft.

[0008] Preferably, the exterior of the main body adopts a rounded corner design.

[0009] Preferably, the exterior of the conventional shaft adopts a spiral design.

[0010] Preferably, the exterior of the chromium-molybdenum alloy steel sandwich base is designed to increase friction.

[0011] Preferably, the driven shaft and the transmission shaft can rotate 360°.

[0012] Preferably, the clamp is fixed to the main body by bolts.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. The utility model can significantly shorten the installation and disassembly time of the workpiece by adding a quick clamping device and a quick mold changing device, reduce manpower consumption and operation time, and thus improve production efficiency. The fixation of the workpiece on the fixture is faster and more convenient, which reduces the downtime of the production line and helps to improve the overall production efficiency. The quick clamping device and the quick mold changing device reduce the manpower and time costs, improve the efficiency of the production process, and also reduce the errors caused by improper or unskilled operation, thereby reducing production costs. The accuracy and stability of the quick clamping device and the quick mold changing device can ensure that the workpiece is firmly and accurately fixed on the fixture, avoiding the situation of loose installation or inaccurate position, which is conducive to improving the accuracy and quality of workpiece processing.

[0015] 2. The utility model has excellent wear resistance and corrosion resistance by adding a chrome-molybdenum alloy steel sandwich base and a chrome-molybdenum alloy steel clamping block, which can effectively resist the wear and corrosion problems caused by long-term use, extend the service life of the fixture and maintain stability. The chrome-molybdenum alloy steel sandwich base and the interlayer have higher hardness and strength, can provide a more uniform and stable clamping force, ensure the stability and precision of the workpiece during the processing, avoid the situation of loose clamping or uneven clamping force, and help improve the quality and precision of workpiece processing. It also has better material strength and stability, which can improve the safety of the use of the fixture, reduce the possibility of accidents, and ensure the safety of operators and equipment. In addition, it can reduce the frequent maintenance and replacement of the fixture, reduce maintenance costs and downtime, and help improve production efficiency and reduce production costs.

[0016] 3. The utility model can achieve precise adjustment of the clamping force of the clamp by adding a pneumatic device and a hydraulic adjustment block. By adjusting the working parameters of the pneumatic device or the hydraulic adjustment block, the clamping force of the clamp can be flexibly controlled to meet the requirements of different workpieces. Problems caused by excessive or insufficient clamping force can be avoided, ensuring the stability and accuracy of the workpiece during processing. By accurately adjusting the clamping force, the position of the workpiece in the clamp can be ensured to be stable and accurate, and problems such as slight offset and deformation can be avoided, thereby improving processing accuracy and product quality. The clamp provides just the right clamping force to ensure that the workpiece maintains the correct position and posture during processing, thereby achieving higher processing accuracy. The vise clamp with adjustable clamping force can flexibly adjust the clamping force according to different types of workpieces, reduce the time for adjusting the clamp and re-clamping, and improve production efficiency.
