Groove cutting machine

Abstract

The slot cutting machine includes one slot cutting worktable with tracks, one motor spindle for the workpiece to be installed on, one backing mechanism capable of controlling the cut slot number and one slot milling mechanism. The backing mechanism includes one transverse guide rail connected to the front side of the motor box, one fixing block, one rotatable index head connected to the fixing block, one locating unit, and at least three adjusting screws and nuts on the index head. The present invention has the advantages including capacity of machining at least three slots simultaneously, simple structure, convenient operation and high slot cutting precision.

Description

Technical field: [0001] The invention relates to a grooving device, in particular to a grooving machine for cutting circumferential grooves on steel workpieces. Background technique: [0002] As shown in Figure 1, the prior art grooving machine generally includes a grooving table 2 provided with a guide rail 1, a motor box 3 installed with a motor (not shown) on the lateral left side of the grooving table 2 , the motor main shaft 4 that is positioned at the right side of the motor box 3, the groove main body mechanism and the mountain mechanism that can control the number of grooves that are installed on the front end of the motor box 3. The main mechanism of the grooving includes a transverse carriage 5 that can move left and right on the guide rail 1, a longitudinal carriage 7 that can move forward and backward on the longitudinal guide rail 6 provided on the transverse carriage 5, and drives the transverse carriage 5 and the longitudinal carriage. 7 moving two planar lin...

AI Technical Summary

Problems solved by technology

[0005] The prior art slotting machine has the following three deficiencies in the actual application process: 1. Due to the limitation of the longitudinal length of the horizontal carriage, the prior art fixed block fixedly connected to the front end of the motor box near the slot milling mechanism is generally only Can rotatably connect one or two rotating blocks that can connect the adjusting bolt 1 on the rotating shaft rod in the middle thereof, so the groove cutting machine in the prior art can only cut one groove or two grooves, and this cutting The structure of the slot machine is also more complicated; 2. The positions of the first slot and the second slot are determined by the length of the two adjusting bolts I mounted on the rotary block, and the length of the adjusting bolt I is determined by adjusting The locking nut II on the bolt rod is completed. During the long-term left and right rotation of the adjusting bolt I with the turning block, the locking nut II will loosen and change its determined position on the bolt rod, so that the groove is in the The position on the workpiece deviates, so the grooving accuracy of the prior art grooving machine is greatly reduced; 3, due to the reasons of the above 2, the operator often needs to adjust the length of the adjusting bolt 1 to ensure that the grooving is required. position, which inevitably increases the cumbersomeness of the operation
