Description

Technical Field

[0001] This utility model relates to the field of knife grinding machine technology, specifically to a multi-functional automatic clamping structure. Background Technology

[0002] Currently, the fixtures used in double-sided grinding machines have simple structures, employing manual material loading and unloading with pin-mounted components. These fixtures suffer from poor rigidity and stability, resulting in inconsistent machining accuracy, long setup times, and an inability to adapt to different workpiece processing requirements. They also fail to meet the needs of automated loading and unloading equipment, hindering mass production. Therefore, to overcome these shortcomings, it is necessary to improve the existing technology. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings and deficiencies in the existing technology and provide a multi-functional automatic clamping structure that is stable in operation and highly versatile.

[0004] This utility model is achieved through the following technical solution:

[0005] A multifunctional automatic clamping structure includes a lower slide plate, an upper slide plate that can move back and forth slidably connected to the top of the lower slide plate, a tool holder central shaft mounted on the upper slide plate, and a front-to-back adjusting screw screw screwed to the central shaft of the tool holder mounted on the lower slide plate. The front-to-back adjusting screw screw is connected to a front-to-back adjusting handwheel. A tool holder is mounted on the top of the upper slide plate, and the central shaft of the tool holder is connected to the tool holder via a central shaft bearing. A tool holder shaft is mounted on the tool holder, and a thrust cylinder is mounted on the right side of the tool holder shaft. The thrust cylinder is connected to a push rod, and an upper push plate and a lower push plate are respectively hinged to the ends of the push rod. An upper jaw is hinged to the end of the upper push plate, and a lower jaw is hinged to the end of the lower push plate. The middle parts of the upper jaw and the middle parts of the lower jaw are hinged to each other via a jaw central shaft.

[0006] Furthermore, the upper slide plate is equipped with slide plate adjustment screws.

[0007] Furthermore, the upper slide plate is equipped with slide plate locking screws.

[0008] Furthermore, a shaft adjusting screw is installed on the top of the tool holder.

[0009] Furthermore, a tool holder adjustment screw is installed on the front side of the upper slide plate.

[0010] Furthermore, the upper jaw is equipped with an upper clamping handle, and the lower jaw is equipped with a lower clamping handle.

[0011] Compared to existing technologies, this invention features a sliding upper slide plate connected to the top of the lower slide plate, allowing for forward and backward movement. The lower slide plate is fitted with a front-to-back adjusting screw threaded to the central shaft of the tool holder. This screw thread is connected to a front-to-back adjusting handwheel. The central shaft of the tool holder is connected to the tool holder via a central shaft bearing. A thrust cylinder is mounted on the right side of the tool holder shaft, connected to a push rod. The ends of the push rod are hinged to an upper push plate and a lower push plate. An upper clamping jaw is hinged to the end of the upper push plate, and a lower clamping jaw is hinged to the end of the lower push plate. The middle portions of the upper and lower clamping jaws are hinged to each other via a clamping jaw central shaft. This allows for adjustment of the clamp's front-to-back position, enabling the tool holder to rotate horizontally for fine-tuning its horizontal position, and allowing the tool holder shaft to rotate for fine-tuning its vertical position. The workpiece can be quickly and precisely adjusted for swing angle via the tool holder shaft. The cylinder pushes the clamp connecting parts to quickly clamp the workpiece for processing. This design is suitable for different workpiece processing requirements, meets the needs of automatic loading and unloading equipment, and is beneficial for mass production. It offers the following advantages:

[0012] 1. The upper and lower sliding plates of this fixture use rigid rails for sliding, which enhances rigidity and stability.

[0013] 2. The tool holder uses a central precision bearing for fixed-point rotation to ensure accuracy and stepless horizontal rotation.

[0014] 3. Combining three adjustable structures, it can effectively reduce machine setup time and be applicable to different workpiece processing techniques, giving this automatic fixture structure the advantages of wide applicability, strong versatility, and high automation.
