A device capable of cutting profiles with precision angles

Abstract

The invention discloses a device capable of achieving precise angle cutting of a profile. The device comprises a base, a screw nut base, a screw, a following pressing plate, a cutting assembly and anangle positioning mechanism; the angle positioning mechanism comprises a pointer, a second rotating shaft, a fastening pressing plate, an angle scale and a connection support; the connection support is fixed to the base and is located on the left side of the following pressing plate, an upper horizontal plate and a lower horizontal plate which are parallel are arranged on the right side face of the connection support, and form a hinge base, a horizontal mounting base is arranged on the left side face of the fastening pressing plate and is hinged to the hinge base of the connection support, a locking bolt perpendicular to the upper horizontal plate is arranged on the upper horizontal plate, the fastening pressing plate is locked on the hinge base through the locking bolt, angle indexes arearranged on the angle scale, the angle scale is horizontally mounted on the fastening pressing plate, the lower end of the pointer is fixed to the connection support, and the upper end of the pointeris located above the angle scale. The cutting angle of the profile can be rapidly and precisely positioned, and an outer measuring tool is not needed.

Description

technical field [0001] The invention belongs to profile cutting machines, in particular to a device capable of cutting profiles with precision angles. Background technique [0002] In the fields of prototype car modification and model skeleton production, a large number of profiles with various angle interfaces are required. The profiles purchased in the market are basically of fixed specifications. When using profiles, manual cutting is required. The main tool used for manual cutting is manual cutting machine. , whose organization is as Figure 4 (cutting disc motor assembly is omitted), it consists of a base 1, a second limit bolt 19, a first rotating shaft 9, a third rotating shaft 18, a fastening plate 5, a lead screw nut seat 6, and a lead screw 7 , fastening rod 8, follow-up platen 10 and cutting sheet 11 are formed. The working principle of the mechanism is: before cutting the profile, the cutting piece 11 is in a lifted state. First, the operator puts the profile to...

AI Technical Summary

Problems solved by technology

[0003] (1) The non-90° cutting angle cannot be precisely positioned by itself, and can only be positioned with the help of external measuring tools, which not only has a large error, but also is cumbersome to operate;

[0004] (2) When adjusting the angle of the fastening platen, it is necessary to use a tool to loosen the second limit bolt and the third rotation shaft at the same time, which will cause trouble in angle adjustment
