Threading machine

Abstract

The invention relates to a threading machine. The threading machine comprises a machine body and a driver, wherein the machine body is internally provided with a transmission component; the driver isin transmission connection with the transmission component; the upper end of the machine body is provided with a threading guiding component; the threading guiding component comprises a left synchronous belt and a right synchronous belt; a left driving pulley and a right driving pulley arranged longitudinally are arranged on two sides of the upper end of the machine body respectively; a left driven pulley is arranged on the right side of the left driving pulley at the upper end of the machine body, and a right driven pulley is arranged on the rear side of the right driving pulley at the upperend of the machine body; the synchronous belt is arranged outside the left driving pulley and the left driven pulley; the right synchronous belt is arranged outside the right driving pulley and the right driven pulley; and a gap between the left synchronous belt and the right synchronous belt serves as a threading gap. According to the threading machine, the synchronism of a traction threading lead is high, synchronous traction of a cable is carried out through mutual clamping of the left synchronous belt and the right synchronous belt, in the transmission process, power needs to be output tothe left driving pulley and the right driving pulley, and the left driven pulley, the right driven pulley, an additional left intermediate pulley and an additional right intermediate pulley are drivenby the synchronous belts.

Description

technical field [0001] The invention belongs to the field of manufacturing cable guiding and threading equipment, and in particular relates to a threading machine. Background technique [0002] In the prior art, for example, the patent publication number is: CN208623240U, which discloses a threading mechanism of a threading machine, which includes a box body, and a worm is threaded inside the box body, and a left worm drive assembly and a right worm gear are respectively engaged on both sides of the worm. The transmission assembly, the right worm gear transmission assembly includes a right worm gear that is rotatably arranged in the box body, and the right traction wheel is arranged above the right worm gear; the left worm gear transmission assembly includes an inner box, and the inner box is rotatably arranged on the worm and can be opposed to the worm Rotate, the inner box is provided with a left turbine, the left traction wheel is arranged above the left turbine, and the ...

AI Technical Summary

Problems solved by technology

[0003] 1. It is necessary to drive the opposite left traction pulley and right traction pulley at the same time. During the threading and lead-in process, the left traction pulley and the right traction pulley need to rotate synchronously. However, this patented product is affected by its transmission structure and cannot ensure long-term traction. The synchronization of the pulleys leads to poor stability and is prone to jamming, that is, due to the low precision of the transmission of the worm gear itself, the synchronization of each traction wheel is poor; while the worm wheel driven by the worm is connected coaxially with each traction wheel, due to the worm gear The transmission generates a lot of heat. With the passage of time and the increase of the frequency of use, the wear of the worm gear is gradually serious until the transmission structure is damaged.

[0004] 2. Since the worm gear can self-lock in reverse, when the cable is transported in place or the worker stops the machine during use and pulls back along the cable with the machine, it is easy to cause the worm gear to self-lock. If things go on like this, the worm gear will be seriously damaged

[0005] 3. The box body of this patented product can rotate around the worm, and the worm wheel connected to the box body rotates at the same time as the meshing transmission with the worm, that is, the position adjustment mechanism has poor transmission stability and coordination due to its structural characteristics in actual use. With the passage of time and the increase of frequency of use, the transmission noise is also getting louder

[0006] 4. Several pairs of traction wheels on both sides interact to feed the wires. The traction wheels have been used for a long time and wear a lot, resulting in high repair and maintenance costs. That is, the traction wheels need to be replaced in time, and the replacement operation is complicated, and subsequent problems are also difficult. many
