Description

Technical Field

[0001] This utility model relates to the field of knife grinding machine technology, specifically to a knife holder clamping device for a knife grinding machine. Background Technology

[0002] The tool holder clamping device is one of the core components of a knife grinding machine. Its main function is to fix and support the tool, ensuring its stability during the grinding process. It supports the tool and securely fixes it to the holder plate. It can be flexibly adjusted according to the size and shape of the tool to accommodate different types of tools. The design of the tool holder clamping device fully considers humanization, safety, and practicality, making the knife grinding process more convenient and efficient, and greatly improving the service life and machining accuracy of the tool. With this device, the knife grinding machine can better serve the grinding needs of various tools.

[0003] According to Chinese Invention Publication No. CN114290134A, an automatic knife sharpening device is disclosed. 1. In this invention, an automatic knife sharpening structure is adopted. A triangular frame, a sliding column, a sliding sleeve, a knife holder, a sharpening block, and a U-shaped frame are set on the top of the base. At the same time, a drive motor, a rotating disc, a transmission shaft, and an O-shaped guide rail are set between the base and the U-shaped frame. When the limiting stud on the knife holder is unscrewed outward from the locking cylinder on the sliding sleeve, the locking state between the knife holder and the sliding sleeve can be released. The sharpening block with a suitable cutting edge angle can then be adjusted to the top of the knife holder. When the drive motor is powered on, it will drive the rotating disc to rotate. Under the transmission action between the transmission column and the O-shaped guide rail, the sharpening block on the knife holder will swing back and forth horizontally, thereby sharpening the knife body on the clamping plate. This structure can adjust and clamp the knife body and perform automatic sharpening, reducing the workload of the operator, thus comprehensively improving the convenience and efficiency of knife sharpening. 2. In this invention, a self-adjusting clamping structure is adopted. The clamping plate is equipped with a transverse groove, an L-shaped frame, a screw sleeve, a front frame, a second electric hydraulic cylinder, a rubber clamping block, a dual-axis motor, and a double-headed screw. When the dual-axis motor is powered on, it drives the double-headed screw to rotate. Under the transmission action between the double-headed screw and the screw sleeve, the two L-shaped frames slide synchronously inward or outward within the transverse groove of the clamping plate, thereby limiting and clamping both ends of the tool body in the X-axis direction. When the second electric hydraulic cylinder extends outward, it drives the rubber clamping block to move backward, thereby pressing the tool body against the clamping plate along the Y-axis direction. This structure allows for the adjustment and clamping of tool bodies of different sizes, improving the stability of tool body clamping and grinding, and also enhancing the applicability of the grinding device.

[0004] However, there are some issues to consider when implementing the above technical solutions: First, the device only clamps the blade on both sides. During sharpening, the blade may shake due to insecure fixing, causing blade damage and safety accidents. Second, the device rigidly fixes the blade during sharpening. If the force is uneven or vibrated suddenly, the device may not be able to counteract the force, which may also cause blade damage. Utility Model Content
