Description

TECHNICAL FIELD

[0001] The utility model relates to numerical control machine tool blade detection technical field especially, based on automatic lathe processing's blade edge precision detection device. BACKGROUND

[0002] The blade of automatic lathe processing is the key tool component for automatic lathe cutting processing, which directly affects the quality and precision of the processed workpiece. The reason why the precision of the blade edge of automatic lathe processing needs to be detected is that the precision of the blade edge is related to the accuracy of cutting, the flatness of the workpiece surface and the accuracy of the size, etc. The precision detection includes straightness detection of the blade edge, checking whether the blade edge is straight and smooth; sharpness detection and roughness detection of the blade edge to determine the smoothness of the surface and the cutting effect; and angle detection of the blade edge to ensure that the cutting angle meets the processing requirements.

[0003] The blade edge precision detection device for detecting the cutting sharpness of the blade generally includes a fixing structure, a loading structure, a cutting material and a measuring structure. The fixing structure is used to stabilize the blade to ensure that the position of the blade does not shift during the detection process. The loading structure can apply a certain pressure to the blade to simulate the downward pressure in the actual cutting process. The cutting material is generally a soft material with standard specifications (such as paper, rubber, etc. of a certain thickness), which is used as the object of the blade cutting. The measuring structure is used to record the relevant data during the cutting process, such as the cutting force, the cutting depth and the cutting speed. The working principle is that the loading structure makes the blade act on the cutting material with a set pressure. During the cutting process of the blade, the measuring structure collects physical quantity data during the cutting process. According to these data (such as smaller cutting force, which represents a sharper blade to a certain extent), the sharpness of the blade cutting is evaluated.

[0004] In the prior art, different types of blades differ in shape, size, thickness, etc. The clamping structure of the device is usually designed according to a specific size and shape, which is difficult to flexibly adapt to various changes, making it difficult for some devices to adaptively clamp and fix different types of blades. This requires manual adjustment or replacement of the clamping device every time the blade type is changed, which slows down the entire detection process. When facing the detection task of multiple types of blades, multiple clamping devices are needed to adapt, increasing the cost and complexity of the equipment. Therefore, the blade edge precision detection device based on automatic lathe processing is proposed to solve the above problems. UTILITY MODEL CONTENTS

[0032] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

The bottom of the sliding table 8 is fixedly connected with a groove plate 10, the groove plate 10 is in a groove-shaped structure, provides a containing and mounting space for internal components, and provides a sliding track for subsequent structures. The bottom of the groove plate 10 is slidably connected with a sliding seat 11, and the bottom of the groove plate 10 is slidably connected with a fixing seat 12, the sliding seat 11 and the fixing seat 12 can easily slide on the bottom surface of the groove plate 10, so as to control the fixing operation of the subsequent structure on the blade.

The outer wall of the proximal side of the two extension plates 13 is respectively fixedly connected with a plurality of suction cups 14, the movement of the extension plates 13 drives the suction cups 14 to move synchronously until the suction cups 14 contact the blade, so that the suction cups 14 are pressed, and the suction cups 14 can exhaust air to form negative pressure when being pressed, thereby firmly adsorbing the blade. The layout of the plurality of suction cups 14 uniformly applies force from multiple angles, so that the blade is balanced in force, and deformation of the blade edge due to uneven local force is avoided.
