Embodiment 1

[0018] The thread cutting device that ensures uniform tangent includes a scribing base 7 and a scribing knife 13 installed on the scribing base 7. The scribing base 7 includes a fixing seat 6, a connecting seat 10, and a mounting seat 8 connected to the connecting seat 10. And the upper and lower two blocking pieces 9 that are connected with the fixed seat 6, wherein the upper and lower two blocking pieces 9 are connected with the connecting seat 10 through a rotating shaft; The connected hollow second assembly part 2 and the knife 3, the knife 3 is slidably arranged in the cavity structure formed by the first assembly part 1 and the second assembly part 2, and the bottom of the first assembly part 1 is provided with The installation hole 11 ; the marking knife 13 also includes an elastic element 4 , one end of the elastic element 4 presses against the top of the knife body of the marking knife 3 , and the other end presses against the inner wall of the top of the second assemb...

Embodiment 2

[0021] In this embodiment, on the basis of Embodiment 1, the inner diameter of the first assembly part 1 is equal to the maximum diameter of the blade of the knife 3, and the inner diameter of the mounting hole 11 is smaller than the maximum diameter of the blade of the knife 3.

[0022] The inner diameter of the first assembly part 1 is equal to the maximum diameter of the knife body of the knife 3 , and the effect of limiting the radial shaking of the knife 3 can be achieved during the working process of the knife 3 . The inner diameter of the mounting hole 11 is less than the maximum diameter of the blade body of the scratching knife 3, so that the scratching knife 3 will not fall off therefrom when moving up and down in the clamp.

Embodiment 3

[0024] In this embodiment, on the basis of Embodiment 1, the elastic element 4 is a spring.

[0025] An elastic element 4 is arranged above the knife 3 , the elastic element 4 is a spring, one end of the spring is against the top of the knife 3 , and the other end is against the inner wall of the top of the second assembly part 2 . In the initial state, the lowering fixture lowers the scribing knife 3 to a preset position and compresses the spring to a certain extent. When the scribing knife 3 touches the depression on the scribing surface, the scribing knife 3 is pushed out by the restoring force of the spring. Touching the concave surface, when the scribing knife 3 touches the convex part of the scribing surface, the scribing knife 3 is lifted, and the spring is compressed again and at the same time gives the scribing knife 3 a reaction force to make the scribing knife 3 complete the work of scribing, thus The self-adjustment function of the scribing knife 3 in the scribing ...

Abstract

The invention records a line cutting device capable of guaranteeing uniform line cutting. The line cutting device comprises a scribing pedestal and a scribing knife which is arranged on the scribing pedestal, wherein the scribing pedestal comprises a fixed seat, a connecting seat, a mounting seat and upper and lower blocking pieces; the mounting seat is connected with the connecting seat; the upper and lower blocking pieces are connected with the fixed seat and are connected with the connecting seat through a rotating shaft; the scribing knife comprises a first hollow assembly part, a second hollow assembly part and a knife; the second assembly part is connected with the first assembly part; the knife is arranged in a cavity structure constituted by the first assembly part and the second assembly part in a sliding manner; the bottom of the first assembly part is provided with a mounting hole; the scribing knife also comprises an elastic element; one end of the elastic element is abutted against the top of the knife body of the knife, and the other end of the elastic element is abutted against the inner wall of the top of the second assembly part. According to the device, the scribing knife can rotate as required, the function that scribing planes in various directions can be scribed by the knife is realized, and the depth of cutting can also be automatically adjusted by the knife through the spring so as to guarantee uniform scribing.

Description

technical field [0001] The invention relates to a thread cutting device, in particular to a thread cutting device for ensuring uniform thread cutting. Background technique [0002] Now, woodworkers often use a scribe knife to scribe lines in slotting, starting lines, etc., but because the depth of the knife is very small, the distance between the blade and the surface of the wood board after the knife is lowered is constant, and it is not suitable for slight fluctuations on the surface of the wood board. The phenomenon of uneven marking or missing marking will eventually affect the entire processing accuracy. And the marking knife can't rotate, can only carry out marking to the plank that is positioned at horizontal position, has bigger limitation. Contents of the invention [0003] The invention provides a thread cutting device that ensures uniform thread cutting, and aims to solve the problems of uneven scoring, non-rotatable scoring knife and the like in the prior art....
