The terms "first," "second," and similar terms used in this application do not indicate any order, quantity, or importance, but are simply used to distinguish different components.

[0039] The embodiment of the present application discloses a clamping device.

The guide rail 6 passes through the slider 7, and the slider 7 slides in engagement with the guide rail 6. A positioning groove 13 is defined on the base 1, and the guide rail 6 is mounted in the positioning groove 13. This ensures the installation accuracy and stability of the guide rail 6 and improves the stability and reliability of the sliding seat 2 during the sliding process.

[0041] Reference Figure 2 , the sliding cooperation between the sliding seat 2 and the base 1, and the driving of the sliding seat 2 by the sliding drive 3, enable the clamping mechanism 4 to move flexibly on the base 1, thereby improving the flexibility and applicability of the clamping device. The sliding drive 3 can adopt an electric motor, a hydraulic motor or a cylinder, and the specific choice depends on the actual application scenario and needs. For example, in application scenarios that require high precision and low noise, a stepper motor or a servo motor can be selected; in application scenarios that require large torque and high load, a hydraulic motor can be selected. A circular avoidance hole 15 is also provided on the support 12. When the sliding drive 3 is a cylinder, the avoidance hole 15 allows the piston rod or related moving parts of the cylinder to have sufficient movement space when driving the sliding seat 2 to slide, thereby avoiding interference with the support 12 or other parts.

The bottom of the guide groove 422 is also provided with a through hole 423 that penetrates the sliding hole 421. The driving inclined rod 431 passes through the through hole 423 and slides with the through hole 423.

[0044] Reference Figure 3 and Figure 4 The driving block 44 on the piston rod of the driving cylinder 41 slides with the sliding hole 421 on the guide seat 42, realizing the conversion of the linear motion of the driving cylinder 41 into the lateral movement of the clamping assembly 43, thereby realizing the function of clamping and releasing the workpiece. The clamping assembly 43 includes a driving bevel rod 431, a guide block 432 and a clamping portion 433. The driving bevel rod 431 slides with the driving bevel hole 441 on the driving block 44, ensuring the stability and accuracy of the clamping action. The sliding cooperation between the guide block 432 and the guide groove 422, as well as the through hole 423 at the bottom of the guide groove 422, enable the driving bevel rod 431 to smoothly transmit power, thereby improving the working efficiency and reliability of the clamping mechanism 4. The different sliding directions of the driving bevel rod 431 and the guide block 432 further enhance the uniform distribution of the clamping force and avoid damage to the workpiece during the clamping process.

These four first bolts 8 engage with the drive cylinder 41 in a threaded manner, thereby achieving a secure connection between the guide base 42 and the drive cylinder 41. This ensures the relative positions of the components remain stable during the drive process, improving clamping accuracy and reliability. Furthermore, this threaded engagement facilitates assembly and disassembly, facilitating maintenance and replacement.

[0048] Continue to refer to Figure 3 Four second bolts 9 are also threaded through the guide base 42.

The position sensor 14 interacts directly or indirectly with the sliding base 2 to provide feedback signals regarding the distance traveled and the current position of the sliding base 2. By reading these signals, the control system can precisely control the operation of the sliding drive 3, ensuring that the sliding base 2 and the clamping mechanism 4 accurately reach the predetermined working position, thereby achieving high-precision operation and automated control of the clamping device. This not only improves the operating efficiency of the clamping device, but also enhances its stability and reliability.

[0051] The implementation principle of this embodiment is as follows: by adding structures such as a base 1, a sliding seat 2 and a sliding drive 3, the overall movement and adjustment of the clamping mechanism 4 on the production line or workbench is realized.
