Description

Technical Field

[0001] The present invention belongs to the technical field of supporting rollers and relates to a follow-up supporting mechanism for a cutting machine. Background Art

[0002] At present, the cutting of small-sized profiled bars and round wire rods by a pipe cutting machine is relatively common, but there are great hidden dangers when cutting large-sized square and profiled bars. The main manifestations are as follows: 1. Currently, the supporting rollers are mainly pneumatically lifted supporting rollers. When the profiled bar is engraved or truncated and rotated, a height difference is generated, which impacts the pneumatic supporting table. At the same time, it directly impacts the chuck. Over time, the accuracy of the chuck is affected. 2. Pneumatic lifting is not easy to control. Since the cutting machine can process a wide range of profiled bar models, the lifting height fluctuates greatly and is not easy to adjust. 3. The length of the cut material is uncertain, ranging from a few millimeters to six or seven meters at most. If the longer and heavier cut workpieces are not supported, accidents are very likely to occur. Summary of the Invention

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The following combines the drawings to describe a specific embodiment of the present invention in detail, but it should be understood that the protection scope of the present invention is not limited by the specific embodiment.

[0021] Example 1:

[0022] As Figures 1-4As shown in the figure, a follow-up material supporting mechanism for a cutting machine includes a material supporting roller group 1 and a distance sensor 2. The material supporting roller group 1 and the distance sensor 2 are carried and driven by a Z-axis reciprocating follow-up mechanism 3, so that they follow the Z-axis reciprocating follow-up mechanism 3 to reciprocate along the Z-axis. The distance sensor 2 can be a capacitive height adjuster, which has high precision and can achieve high-precision follow-up adjustment. Specifically, the material supporting roller group 1 and the distance sensor 2 are carried by a Z-axis fixing plate 4, and the Z-axis fixing plate 4 is fixed on the Z-axis sliding support plate 31 of the Z-axis reciprocating follow-up mechanism 3. The Z-axis reciprocating follow-up mechanism 3 is a Z-axis linear module and is driven by a Z-axis follow-up motor 32;

[0023] The distance sensor 2 is connected to the control system, transmits the distance signal to the control system, and the control system compares it with the set value accordingly, and then controls the corresponding movement adjustment of the Z-axis reciprocating follow-up mechanism 3, so that the material supporting roller group 1 follows the workpiece 7 for follow-up, and the supporting roller in the material supporting roller group 1 is in tangential contact with the workpiece 7.

[0024] The distance sensor 2 is driven by an X-axis reciprocating follow-up mechanism 5 to reciprocate with the X-axis reciprocating follow-up mechanism 5 for tracking the minimum rotational height difference of the workpiece 7. The X-axis reciprocating follow-up mechanism 5 is carried by the Z-axis fixing plate 4. The X-axis reciprocating follow-up mechanism 5 is an X-axis linear module and is driven by an X-axis follow-up motor 51. The X-axis reciprocating follow-up mechanism 5 moves at the same speed and synchronously with the cutting head 8 of the cutting machine, but in the opposite direction. The workpiece 7 rotates clockwise, the cutting head 8 moves to the left, and the X-axis reciprocating follow-up mechanism 5 moves to the right at the same speed and synchronously. When the cutting head 8 runs to the leftmost side, the X-axis reciprocating follow-up mechanism 5 drives the distance sensor 2 to move to the rightmost side, and the sensing point of the distance sensor 2 is at the rightmost end, that is, at the minimum rotational height difference with the workpiece 7. At this time, the detection error is very small or negligible. Therefore, detecting the height difference at this point ensures its accuracy, so that the height of the material supporting roller group 1 can be adjusted with high precision to avoid unnecessary collisions and cause unnecessary damage to the workpiece 7 and the machine body.

[0025] Embodiment 2: On the basis of Embodiment 1, a Z-axis lifting mechanism 6 is added. The Z-axis reciprocating follow-up mechanism 3 is carried by the Z-axis lifting mechanism 6 and reciprocates with the Z-axis lifting mechanism 6. The Z-axis lifting mechanism 6 includes a lifting movable plate 61, a fixed seat 62 and a lifting driving member 63. The lifting movable plate 61 is slidably connected to the fixed seat 62 and is driven by the lifting driving member 63 to move. The lifting movable plate 61 is slidably connected to the fixed seat 62 through a guide rail. The lifting driving member 63 is a lifting cylinder or a lifting hydraulic cylinder, and the lifting movable plate 61 is a "T" - shaped plate.

[0026] The function of the Z-axis lifting mechanism 6 is to lift the cut workpiece 7 and facilitate the avoidance of the rear chuck during feeding;

[0027] The above are only several specific embodiments of the present invention. However, the embodiments of the present invention are not limited thereto, and any changes that can be conceived by those skilled in the art shall fall within the protection scope of the present invention.
