Description

Technical Field

[0001] The utility model relates to the technical field of positioning detection, in particular to a rear positioning automatic adjustment device. Background Art

[0002] In the process of bending sheet metal using a bending machine, the rear stop finger is required to limit the placement of the material to calibrate the bending position of the material. This process is called post-positioning, and then the bending operation is performed. Usually, the post-positioning process requires the cooperation of at least two rear stop fingers. On traditional bending machines, the two rear stop fingers are manually adjusted so that the two are on the same straight line to ensure bending accuracy. On CNC bending machines, due to the movement accuracy of components such as cylinders, motors, and transmission guides, the resident positions of the two rear stop fingers are not on the same straight line, and at this time, the CNC panel will still indicate that the two are accurately positioned, thereby producing defective products. In addition, if the post-positioning accuracy is repeatedly measured manually during the bending process, it will seriously reduce production efficiency and increase labor costs.

[0027] DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] See also Figures 1 to 3 , the rear positioning automatic adjustment device may include the following contents.

[0030] A bottom plate 1 with an assembly groove 11 and a limit groove 12 on the bottom surface;

[0031] The sensor 2 is assembled inside the assembly groove 11, and the positioning block 3 is slidably assembled inside the limit groove 12;

[0032] A spring 4 is mounted on one end of the sensor 2, and a signal cable 21 is arranged on the other end;

[0033] The sensor 2 is elastically connected to the inner end of the positioning block via a spring 4;

[0034] The bottom surface of the base plate 1 is mounted with a cover plate 5 .

[0035] Here, the positioning block contacts the material, the spring is squeezed, and a force is applied to the sensor, and the sensor outputs the measured force parameters;

[0036] It is understandable that for a spring with known specifications, when it is compressed to different degrees, the forces generated on the two ends are also different, and the higher the compression degree, the greater the force generated. Based on this, when the specifications of the spring are clear, the current compression degree of the spring, that is, the relative position of the positioning block in the limit groove, can be inferred based on the force parameters measured by the sensor, so as to know the relative position of the material relative to the current rear stop finger.

[0037] Therefore, by measuring the relative position of the material and different rear stop fingers on the same bending machine, it is possible to know whether the rear stop fingers are aligned and in the same straight line, and then correct the rear stop fingers that are not accurately positioned or not in the right position to ensure bending accuracy.

[0038] In this embodiment, one side of the limiting groove 12 is connected to the assembly groove 11 , and the other side is provided with a through hole penetrating the side surface of the bottom plate 1 .

[0039] In this embodiment, the two sides of the middle of the positioning block 3 are outward-facing side wings 31;

[0040] The width of the side wing 31 is adapted to the width of the limiting groove 12 , and the height of the side wing 31 is smaller than the height of the limiting groove 12 .

[0041] In this embodiment, the positioning block 3 slides along the axial direction of the limiting groove 12 , and an outer end of the positioning block 3 slides out of the through hole on the side of the bottom plate 1 .

[0042] Here, the limit groove is used to limit the axial movement limit of the positioning block to avoid excessive protrusion affecting the measurement accuracy, so as to dynamically measure the specific position of each rear stop finger on the bending machine.

[0043] In this embodiment, the bottom plate 1 is fixedly mounted on the rear stop finger of the bending machine, and one outer end of the positioning block 3 is supported against the edge of the material.

[0044] In this embodiment, the sensor 2 measures the force exerted by the spring 4 on it.

[0045] In this embodiment, the signal cable 21 outputs the force generated by the spring measured by the sensor 2 .

[0046] Here, the material limits the positioning block, the positioning block compresses the spring, the spring generates a force on the sensor, the sensor measures the force and outputs it through the signal cable.

[0047] Therefore, the external signal comparison device can receive the electrical signal representing the force output by the sensor on each rear stop finger through the signal cable, thereby converting the force into the compression data of the spring, and then converting the compression data of the spring into the relative position data of the positioning block in the limit groove, and then further converting to obtain the relative position data of each rear stop finger and the material. At this point, the relative position information of each rear stop finger involving the same material on the same bending machine can be accurately known, and the rear stop finger with resident misalignment can be identified from it for targeted positioning and correction.

[0048] In this embodiment, a mounting hole 13 is provided at one end of the bottom plate 1 for fixing the bottom plate 1 on the rear stop finger of the bending machine.

[0049] In this embodiment, a cable hole 14 is provided in the middle of one end of the bottom plate 1 , and the cable hole 14 is used for laying a signal cable 21 or a power cable.

[0050] In this embodiment, an ejector hole 15 is axially defined at one end of the cable hole 14 for the ejector of the bending machine to penetrate.

[0051] Compared with the prior art, the embodiments of the present invention have the following beneficial effects:

[0052] The actual position of the rear stop finger on the bending machine is measured by the positioning block, so as to compare the actual position of each rear stop finger on the same bending machine, and correct the rear stop finger with inaccurate residence position, so that each rear stop finger is in place to ensure bending accuracy. No manual intervention is required in the process, which effectively improves production efficiency and reduces labor costs.
