Lathe tool for machining helical groove

Abstract

The invention relates to a lathe tool for machining a helical groove. The lathe tool for machining the helical groove comprises a pedestal, the pedestal is provided with a rotating shaft which is connected with the pedestal in a rotary manner, the rotating shaft is provided with a rotary table, a tool rest is fixed on one side of the rotary table, the tool rest is provided with a plurality of mounting racks, each mounting rack is fixed with a tool bit, the end portion of the rotating shaft is provided with a rotating handle, and the rotary table is provided with a positioning bolt which can abut against the pedestal. The pedestal is provided with the rotating shaft which is connected with the pedestal in a rotary manner, the rotating shaft is provided with the rotary table which can rotate freely, the tool rest is fixed on one side of the rotary table, the tool rest is provided with a plurality of mounting racks, each mounting rack is fixed with one tool bit, in this way, the tool rest, the mounting racks and the tool bits all can rotate along with the rotary table, and therefore adjustment is carried out, the tool rest, the mounting racks and the tool bits can be suitable for the helical groove needing to be turned. The end portion of the rotating shaft is provided with the rotating handle, and the operator can operate the rotating angle of the rotary table by means of the rotating handle conveniently, the rotary table is provided with the positioning bolt which can abut against the pedestal, in this way, after the angle is adjusted appropriately, the rotary table can be positioned.

Description

technical field [0001] The invention relates to the field of machining equipment, in particular to a turning tool for machining spiral grooves. Background technique [0002] The large-pitch spiral grooves currently on the market are machined with a single turning tool, and the spiral grooves of the inner barrel are composed of many spiral grooves with a single pitch of 700mm. One turn, the turning tool needs to move 700 mm in the horizontal direction. Even if the lowest speed (5 revolutions per minute) is used for processing, the lateral movement speed of the lathe carriage is still very fast during the working process, and the lowest speed is 5 revolutions per minute. For example, every 12 seconds, the carriage of the lathe moves 700 mm. Since the helix angle of the large pitch is 36°, this requires that the back angle of the turning tool must be greater than 36°. When the back angle of the turning tool is greater than 36°, The mechanical strength of the traditional turnin...

[0002] The large-pitch spiral grooves currently on the market are machined with a single turning tool, and the spiral grooves of the inner barrel are composed of many spiral grooves with a single pitch of 700mm. One turn, the turning tool needs to move 700 mm in the horizontal direction. Even if the lowest speed (5 revolutions per minute) is used for processing, the lateral movement speed of the lathe carriage is still very fast during the working process, and the lowest speed is 5 revolutions per minute. For example, every 12 seconds, the carriage of the lathe moves 700 mm. Since the helix angle of the large pitch is 36°, this requires that the back angle of the turning tool must be greater than 36°. When the back angle of the turning tool is greater than 36°, The mechanical strength of the traditional turning tool is extremely low, so the cutting efficiency is extremely low. It takes 3-4 working days to process the spiral groove of an inner bobbin
