Description

Technical Field

[0001] This utility model belongs to the field of cutting tooth processing technology, and in particular relates to a fixing device for cutting tooth processing. Background Technology

[0002] Cutting teeth are key wear parts widely used in mining, tunneling and other engineering projects. They are mainly used to cut hard materials such as coal seams and rocks. They are usually composed of three parts: the tooth head, the tooth body and the tooth shank. The tooth head is the part that directly contacts the rock and has high hardness and wear resistance. The tooth body is the main part that supports the tooth head and has good toughness and impact resistance. The tooth shank is the part that fixes the cutting tooth and fits tightly with the cutting tooth holder.

[0003] During machining processes such as turning, milling, and grinding, cutting teeth need to withstand cutting forces, impact forces, and vibrations. In order to prevent the cutting teeth from shifting and causing wavy vibration marks on their surface, which would affect wear resistance, a fixing fixture is required to fix the cutting teeth. When using a fixing fixture to install and fix the cutting teeth, manual installation is required. The installation process requires manual adjustment of the fixture, which is time-consuming. Furthermore, the uncertainty of manual operation may lead to fluctuations in the fixing quality, affecting the dimensional accuracy and surface quality of the cutting teeth. Utility Model Content

[0026] The working principle of this utility model:

[0027] When clamping and fixing the cutting tooth, insert the tooth shank into the inner cylinder 103, start the drive motor 502, and the output end of the drive motor 502 drives the drive gear 503 to rotate. During the rotation of the drive gear 503, the first screw 301 and the second screw 401 are driven to rotate through the first gear 303 and the second gear 405 respectively. During the rotation of the two first screws 301, the extrusion ring 302 is driven to move upward. During the movement of the extrusion ring 302, the extrusion ring 302 extrudes multiple extrusion cylinders 202, causing the multiple extrusion cylinders 202 to move inward. During the rotation of the two second screws 401, the lifting ring 402 is driven to move downward. During the movement of the lifting ring 402, multiple extrusion cylinders 202 are driven to move inward. The connecting block 403 drives the lifting plate 404 to move downward. After the multiple extrusion cylinders 202 move inward, they clamp and fix the cutting tooth, keeping it stable. After the cutting tooth is processed, the drive motor 502 is started to reverse. During the reverse rotation of the two first screws 301, the extrusion rings 302 move downward. The multiple reset springs 203 rebound, driving the multiple extrusion cylinders 202 to move outward. All the extrusion cylinders 202 disengage from the cutting tooth. During the reverse rotation of the two second screws 401, the lifting rings 402 move upward. During the movement of the lifting rings 402, the lifting plate 404 moves upward. The lifting plate 404 pushes the cutting tooth upward, thereby removing the cutting tooth.
