Fastening device for milling machine cutter

Abstract

The invention relates to a fastening device for a milling machine tool. The device comprises a base, a stand column, a cross beam, a fixing block, a positioning plate, a cutter, a supporting mechanismand a connecting mechanism. The cutter comprises a cutter head, a cutter handle, a connecting plate, a positioning block and a moving block; the supporting mechanism comprises a first spring, a firstlimiting block, a piston cylinder, a supporting rod and a second spring; and the connecting mechanism comprises a screw rod and a first screw cap. According to the fastening device for the milling machine cutter, when a worker installs the cutter, the cutter can be fastened through the supporting mechanism, so that a worker can fix the screw cap by two hands, the condition that hands or feet areinjured as one hand cannot hold the cutter due to the too heavy cutter can be avoided, and further the safety during installation is improved. Primary fixing of the cutter is achieved through fixing of a bolt and a positioning strip, the positioning strip can further limit the cutter, the screw rod is more firmly connected with the cutter handle through cooperation of the screw rod and a sleeve, secondary fixing of the cutter is achieved, and the use practicability is improved.

Description

technical field [0001] In particular, the invention relates to a fastening device for milling machine tools. Background technique [0002] A milling machine is a machine tool with a wide range of uses. It can process planes (horizontal planes, vertical planes), grooves (key slots, T-shaped slots, dovetail slots, etc.), toothed parts (gears, spline shafts, sprockets), Spiral surface (thread, spiral groove) and various curved surfaces. In addition, it can also be used to process and cut off the surface and inner hole of the rotary body. When the milling machine is working, the workpiece is installed on the workbench or on the accessories such as the dividing head. , the rotation of the milling cutter is the main movement, supplemented by the feed movement of the table or the milling head, the workpiece can obtain the required processing surface, because it is multi-blade intermittent cutting, so the productivity of the milling machine is high. Simply put, the milling machine ...

AI Technical Summary

Problems solved by technology

[0003] The current vertical ordinary milling machine generally only uses a screw to fix the tool, and when installing, the general staff always climbs to the operating platform, and then installs the tool on the working head with one hand Then the other hand installs the tool by twisting the upper screw, so that when the staff works for a long time, people will be fatigued, resulting in a decrease in physical strength, which will cause a safety accident, and when the tool is replaced , after the milling machine runs for a period of time, it will cause the milling cutter to loosen, and it is necessary to stop the milling machine to tighten the milling cutter, which has a high risk factor and delays production
