[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] Example

[0018] See also Figure 1-2 The utility model provides the following technical solutions: a clamp for a metal cutting machine tool, comprising a reinforcing beam 2, an adaptive adjustment mechanism 4 is arranged at the upper front end of the reinforcing beam 2, three groups of clamping blocks 3 are arranged at the front end face of the adaptive adjustment mechanism 4, a positioning drive device 10 is arranged at the upper end face of the adaptive adjustment mechanism 4, and a positioning sensor 9 is arranged at the front end face of the positioning drive device 10.

[0019] In this embodiment, the adaptive adjustment mechanism 4 realizes its working principle through the following steps:

[0020] First, the adaptive adjustment mechanism has a plurality of retractable clamping blocks 3, one end of which is fixed on the base of the clamp, and the other end is provided with a retractable clamping end. The retractable function of these support arms is realized by the corresponding positioning drive device 10. The positioning drive device 10 can be electric, hydraulic or pneumatic type, and can be selected according to specific needs and application scenarios.

[0021] When workpieces of different sizes or shapes need to be clamped, the positioning drive device 10 will control the telescopic length of the support arm according to a preset program or real-time feedback information, so that the clamping end can adaptively adjust its position and posture to ensure a close fit with the workpiece surface.

[0022] During the adjustment process, the high-precision positioning mechanism plays a key role. The positioning sensor 9 detects the position information of the workpiece in real time, including the position, angle, and posture, etc. This information will be transmitted to the positioning drive device 10, and the positioning drive device 10 will fine-tune the adaptive adjustment mechanism 4 based on this information. Through continuous iteration and adjustment, the clamping end and the workpiece will eventually achieve the best matching state.

[0023] In addition, the adaptive adjustment mechanism 4 also has a certain flexibility and fault tolerance. When there is a slight change in the size or shape of the workpiece, the mechanism can automatically adapt and adjust the position and posture of the clamping end to ensure the stability and reliability of the clamping. This flexibility and fault tolerance is achieved through the design of the mechanism and the selection of materials, which can reduce processing errors and improve processing efficiency to a certain extent.

[0024] In summary, the adaptive adjustment mechanism 4 realizes adaptive clamping of workpieces of different sizes and shapes through the working principles of telescopic support arms, high-precision positioning, flexibility and fault tolerance. This mechanism has important application value in fixtures for metal cutting machine tools, and can improve processing efficiency and precision and reduce production costs.

[0025] The positioning drive device 10 plays a vital role in the adaptive adjustment mechanism. Its working principle is mainly based on accurate position sensing and power transmission. The following is a detailed explanation of the working principle of the positioning drive device 10:

[0026] First, the positioning sensor 9 detects the position information of the workpiece in real time. These sensors can be contact or non-contact, depending on the specific application environment and requirements. The sensor converts the detected position information into an electrical signal and transmits it to the control system.

[0027] After receiving the position information, the control system will compare it with the target position and calculate the deviation value. Then, the control system will generate corresponding control signals based on the deviation value, which will instruct the positioning drive device to take action.

[0028] After receiving the control signal, the positioning drive device 10 starts to work. It may be a power device such as an electric motor, a hydraulic cylinder or a pneumatic cylinder, and the specific type depends on the application requirements and system configuration. The drive device adjusts its output force or motion trajectory according to the command of the control signal to drive the support arm in the adaptive adjustment mechanism to extend or rotate, thereby changing the position and posture of the clamping end.

[0029] During the driving process, the positioning drive device 10 will continue to receive real-time feedback signals from the positioning sensor to monitor the current position state. If there is still a deviation between the current position and the target position, the control system will continue to adjust the control signal to make the drive device continue to move until the target position is reached.

[0030] Through such closed-loop control, the positioning drive device can achieve high-precision positioning of the workpiece. It can quickly respond to the control system's instructions and accurately adjust the position and posture of the clamping end to meet the processing requirements of different workpieces.

[0031] In addition, the positioning drive also has a certain degree of stability and reliability. It can work normally in various working environments and conditions, and has a certain adaptability to changes in the size and shape of the workpiece. At the same time, the structural design and material selection of the drive are also optimized to ensure its stability and reliability in long-term use.

[0032] In summary, the positioning drive device 10 achieves high-precision positioning of the workpiece through precise position sensing, power transmission and closed-loop control. It is an important component of the adaptive adjustment mechanism and provides a stable and reliable positioning function for the fixture of the metal cutting machine tool.
