The invention is capable of other and different embodiments and of being practiced or of being carried out in various ways, and its several details are capable of modification in various respects, all without departing from the spirit and scope of the present invention.
It should be noted that the drawings provided in the present embodiment are only for illustrating the basic idea of the present invention, and the components related to the present invention are only shown in the drawings rather than drawn according to the number, shape and size of the components in actual implementation, and the type, quantity and proportion of the components in actual implementation may be changed freely, and the layout of the components may be more complicated.
The self-piercing riveting point positioning device and the positioning method thereof can quickly position the self-piercing riveting points, are orderly arranged, have uniform space and high positioning efficiency, and greatly improve the user experience.
As shown in fig. 1-3, in an embodiment, the self-piercing rivet point positioning apparatus of the present invention includes:
the positioning seat 1 is used for being fixed on a part, and a linear clamping groove 11 is formed in the upper surface of the positioning seat.
Specifically, the positioning seat 1 is in contact with a part to be calibrated with a self-piercing riveting point and is stably arranged on the surface of the part so as to ensure the accuracy of calibration of the self-piercing riveting point.
In an embodiment of the present invention, a magnetic component 12 is disposed on a lower surface of the positioning seat 1, and the positioning seat 1 is fixed on the component through the magnetic component 12. Preferably, as shown in fig. 3, the magnetic assembly 12 is made of a magnetic strip material.
At least one positioning block 2 arranged in the linear clamping groove 11; the center of the positioning block 2 is provided with a hole 21 for passing through self-piercing riveting point calibration equipment.
Specifically, the upper surface of the positioning seat 1 is provided with a linear clamping groove 11. The positioning block 2 is arranged in the linear clamping groove 11 in a clamping mode. It should be noted that the positioning blocks 2 can flexibly move in the linear slot 11, so that the distance between two adjacent positioning blocks 2 can be adjusted according to needs. When the number of the positioning blocks 2 is larger than two, the positioning blocks 2 are arranged in the linear clamping grooves at equal intervals. Therefore, after the at least one positioning block 2 is arranged at equal intervals, the self-piercing riveting point calibration equipment penetrates through the holes in the positioning block 2, and self-piercing riveting points which are arranged neatly and uniformly in interval can be calibrated on the surface of the part.
It should be noted that the size and shape of the hole 21 depend on the self-piercing riveting point calibration device.
In an embodiment of the present invention, a scale 13 is further disposed on the upper surface of the positioning seat 1; the scale table 13 is parallel to the linear clamping groove 11. Therefore, the scale 13 assists in adjusting the distance between the positioning blocks 2 to ensure that the positioning blocks 2 are arranged at equal intervals.
In order to enable the self-piercing riveting points calibrated in the front and back directions to be located on the same straight line or be parallel to each other, in an embodiment of the present invention, the self-piercing riveting point positioning device further includes a light horizontal positioning component 3, and the light generated by the light horizontal positioning component 3 and the linear clamping groove 11 are located in the same straight line direction. Therefore, the calibrated self-piercing riveting points can be kept on a straight line or parallel to each other by adjusting the position relation between the light rays and the center line of the existing self-piercing riveting points. Specifically, the light and the existing self-piercing riveting point are adjusted to be located in the same linear direction or in a parallel direction, the linear clamping groove 11 and the existing self-piercing riveting point are also located in the same linear direction or in the parallel direction, and the new self-piercing riveting point obtained based on the positioning block 2 is correspondingly located in the same linear direction or in the parallel direction with the existing self-piercing riveting point, so that the regular arrangement of the self-piercing riveting points on the surface of the part is ensured.
In an embodiment of the present invention, the light horizontal positioning component 3 employs a single-line laser level or a single-line infrared level. Preferably, the light horizontal positioning component 3 is located below the linear clamping groove 11 and is arranged on the side surface or in the internal channel of the positioning seat 1. When the light horizontal positioning component 3 is located in the internal channel of the positioning seat 1, the light generated by the light horizontal positioning component 3 needs to pass through the positioning seat 1 and extend to the outside of the positioning seat 1, so as to adjust the position and direction of the positioning seat 1 according to the center line of the existing self-piercing riveting point.
The positioning method of the self-piercing riveting point positioning device of the invention is simply produced below. Specifically, the positioning method of the self-piercing riveting point positioning device comprises the following steps:
and step S1, clamping the at least one positioning block in the linear clamping groove according to a preset distance so as to ensure that the positioning blocks are linearly arranged at equal intervals.
And step S2, fixing the positioning seat on the surface of the part.
The sequence of the step S1 and the step S2 can be adjusted according to actual requirements.
And step S3, performing self-piercing riveting point calibration on the surface of the part on the basis that self-piercing riveting point calibration equipment penetrates through the hole of the at least one positioning block.
After the positioning blocks are arranged at equal intervals, the self-piercing riveting point calibration equipment passes through the hole of the at least one positioning block to perform self-piercing riveting point calibration on the surface of the part, so that self-piercing riveting points which are arranged at equal intervals and in a straight line are calibrated on the surface of the part. Therefore, the positioning of a plurality of self-piercing riveting points can be completed at one time through one positioning seat.
In an embodiment of the present invention, when the light horizontal positioning assembly is disposed on the positioning seat, the method further includes adjusting the positioning seat based on the light horizontal positioning assembly, so that a center line of an existing self-piercing riveting point on the part is located in a same straight line direction or parallel to a light emitted by the light horizontal positioning assembly.
Specifically, in order to achieve the arrangement consistency with the existing self-piercing riveting points, the light rays generated by the light ray horizontal positioning assembly are adjusted to be located in the same linear direction or parallel to the existing self-piercing riveting points, so that the position and the direction of the positioning seat are determined.
In summary, the self-piercing riveting point positioning device and the positioning method thereof can accurately position the self-piercing riveting point based on the single-line horizontal laser and the positioning block; compared with manual calibration, the positioning of the self-piercing riveting points is greatly improved, a plurality of self-piercing riveting points can be positioned on a single positioning block, and the positioning efficiency is high; the self-piercing riveting points are arranged regularly and uniformly, and the phenomena of influence on the appearance quality, such as inconsistent intervals, jumping and the like, are avoided.
