Description

TECHNICAL FIELD

[0001] The utility model relates to track traffic vehicle floor cloth paving auxiliary frock technical field, especially floor cloth angle cutting device. BACKGROUND

[0002] The floor cloth is cut and bonded by the present vehicle research and development mode at the partition wall of the car, and the connection between the floor cloth and the floor is bonded by hot melt glue. The present vehicle research and development mode can avoid the size change caused by the deformation of the floor cloth due to heat, and the size change of the floor cloth cut in advance. Because the floor cloth is paved from the longitudinal center line of the vehicle body to both sides of the vehicle body, the floor cloth angle cutting at the lower partition wall is the last process (as shown in the figure), and the cutting allowance is too large, which causes the floor cloth to interfere with the partition wall and cannot be bonded with the floor. If the cutting allowance is too small, the gap between the partition wall and the floor cloth is out of tolerance. It is more difficult to cut the floor cloth angle at the arc partition wall. Figure 1

[0003] The floor cloth angle cutting at the flat partition wall cabinet requires three operators to complete together. Two operators place the steel ruler on the floor cloth, and one operator cuts the floor cloth according to the edge path of the steel ruler using a wallpaper knife. This operation requires that the actions of the two people controlling the steel ruler be coordinated, and the force of pressing the steel ruler be large. At the same time, the operator holds the wallpaper knife to operate. The floor cloth angle cutting at the arc partition wall is completed by the operator holding the wallpaper knife and cutting and trimming multiple times according to the shape of the arc partition wall, but the operator needs to have high working experience to successfully implement it. In the above two cutting situations, the path control of the knife is controlled by the wrist of the operator, and the cutting path is easy to deviate. At the same time, in the operation process, multiple people cooperate to operate, which is easy to cut wrong. Especially, the floor cloth angle cutting operation at the arc partition wall cabinet requires high skills of the operator, has low production efficiency, and has the risk of material loss due to cutting errors.
