DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0030] The embodiment of the present application provides a riveted ball pin identification device, which can solve the problem in the related art that operators only rely on naked eye observation and personal experience to identify different models, resulting in adverse effects on the quality and performance of the riveted assembly.

[0031] Embodiment 1:

[0032] like Figures 2 to 4 As shown, a riveted ball stud identification device comprises:

[0033] The positioning seat 1 is provided with a ball head receiving groove 101, the width of which should be equal to the maximum diameter of the ball head end where the ball head pin 13 is to be installed, so that the central axis of the ball head pin 13 is collinear with the central axis of the head ball receiving groove 101 to ensure the accuracy of riveting, and the outer side of the entrance of the ball head receiving groove 101 forms a placement area 102 for placing the ball seat 1302;

[0034] A first detector 2, which is located in the ball head receiving groove 101 and is used to measure the distance from the ball head 1301 of the ball head pin 13;

[0035] A detection rod 3 connected to the rotating shaft 4, wherein the movement path of the first end of the detection rod 3 passes through the placement area 102, and the distance between the first end of the detection rod 3 and the rotating shaft 4 is smaller than the distance between the second end of the detection rod 3 and the rotating shaft 4;

[0036] A second detector 5, which is used to detect the movement distance of the second end;

[0037] The driving mechanism 6 is connected to the second end and is used to drive the detection rod 3 to rotate around the rotating shaft 4.

[0038] The ball pin 13 is placed on the positioning seat 1, the ball head 1301 of the ball pin 13 is placed in the ball head receiving groove 101, and the ball seat 1302 is placed in the placement area 102. If the model of the ball pin 13 is greater than the preset value, there are two possibilities:

[0039] In the first case, the end of the ball head 1301 cannot completely enter the ball head receiving groove 101, and the first detector 2 detects that the distance between the bottom of the ball head of the ball head pin 13 and the first detector 2 does not meet the preset value, the green light of the first detector 2 is off, the detection stops, and the non-compliant ball head pin 13 is removed;

[0040] In the second case, the end of the ball head 1301 can be placed in the ball head receiving groove 101, and there are two results. If the length does not meet the preset value, the first detector 2 will not light up, the detection will stop, and the non-compliant ball head pin 13 will be taken out; if the length is normal, the green light of the first detector 2 will be on.

[0041] If the green light of the first detector 2 is on, it means that the length of the ball pin 13 is correct. The driving mechanism 6 is started to drive the detection rod 3 to rotate around the shaft 4, so that the first end of the detection rod 3 passes through the placement area 2 and contacts the ball seat of the ball pin 13. The distance between the first end of the detection rod 3 and the shaft 4 is L1, and the distance between the second end of the detection rod 3 and the shaft 4 is L2. Since L1 is less than L2, the diameter deviation of the ball seat 1302 is amplified by the lever principle and then fed back to the second detector 5. If the diameter is greater than or less than the set value, the green light of the second detector 5 is not on, and the specification of the ball pin 13 is wrong. On the contrary, the green light of the second detector 5 is on, and the specification of the ball pin 13 is correct. Through the first detector 2 and the second detector 5, the ball pin 13 of abnormal model can be identified, which ensures the stability of riveting quality and prevents the occurrence of defective products.

[0042] like Figure 3 As shown, in this embodiment, the ball head receiving groove 101 is a through groove that penetrates the positioning seat 1, and the first detector 2 is located at the lower end of the ball head receiving groove 101 and has a distance from the bottom of the ball head pin 13.

[0043] In some optional embodiments, the ball head receiving groove 101 is a groove that does not penetrate the positioning seat 1, and the first detector 2 is located at the bottom of the groove.

[0044] Further, such as Figure 4 As shown, two placement blocks 103 are fixedly installed on the positioning seat 1. The two placement blocks 103 are symmetrically arranged on both sides of the ball head receiving groove 101, and the opposite side is arc-shaped. The placement area 102 of the ball seat 1302 is formed between the two placement blocks 103.

[0045] Further, such as Figure 4 As shown, a guide groove 104 is provided between the two placement blocks 103 , and the first end of the detection rod 3 can extend into the guide groove 104 .

[0046] Furthermore, the included angle between the guide groove 104 and the axis of the ball head receiving groove 101 is α, 30°<α<90°, and the inclined guide groove 104 is provided to facilitate the push block 301 to abut against the ball seat 1302 of the ball head pin 13 along the inclined surface.

[0047] Further, such as Figure 3 As shown, a push block 301 is provided at the first end of the detection rod 3. The push block 301 is a wedge-shaped block. The push block 301 is inclined at the bottom near one end of the positioning seat 1 to facilitate the push block to enter the placement area 102 along the guide groove 104, thereby abutting the ball seat 1302 of the ball pin 13.

[0048] Further, such as Figure 2 As shown, a protrusion 302 is disposed at the second end of the detection rod 3 , and the second detector 5 is used to detect the movement distance of the protrusion 302 .

[0049] Furthermore, a connecting member 7 is hinged on the second end of the detection rod 3 , and the connecting member 7 is fixedly connected to the output shaft of the driving mechanism 6 .

[0050] In this embodiment, the driving mechanism 6 is a cylinder, which is fixed on the mounting plate, and the output shaft of the cylinder is fixedly connected to the connecting member 7 .

[0051] In some optional embodiments, the driving mechanism is a hydraulic cylinder or other electric driving means.

[0052] In this embodiment, the first detector 2 and the second detector 5 are both proximity sensors, and the first detector 2 is electrically connected to the driving mechanism 6 .

[0053] In some optional embodiments, the first detector 2 and the second detector 5 may also be CCD detectors.

[0054] In some optional embodiments, the first detector 2 and the second detector 5 are connected to an alarm system.

[0055] Embodiment 2:

[0056] like Figure 5 As shown, a riveting tool includes a base 8, which is fixedly mounted on a riveting device by bolts on left and right sides. A first detector 2 and a second detector 5 are electrically connected to the riveting device. A positioning seat 1, a driving mechanism 6, and a second detector 5 are all fixedly mounted on the base 8. A rotating shaft 4 can be fixedly mounted on the base 8 or on the positioning seat 1, as long as the detection rod 3 can rotate around the rotating shaft 4.

[0057] The workpiece 12 is an engine bracket, which is a U-shaped structure as a whole, with mounting ears on both sides, mounting holes on the mounting ears, other parts are welded to one side of the U-shaped structure, and a positioning hole is provided at the bottom for installing the ball stud 13.

[0058] Two support frames 9 are fixedly installed on the base 8, and the support frames 9 are symmetrically arranged on both sides of the positioning seat 1. The distance between the two support frames 9 can be used to place the workpiece 12. The support frames 9 are provided with positioning pins 10, and the mounting holes on both sides of the workpiece 12 can be inserted into the positioning pins 10 to limit the workpiece 12.

[0059] Since the two sides of the workpiece 12 are different, in order to prevent the workpiece 12 from being loaded in an incorrect direction, an anti-error rod 11 is provided on the positioning seat 1 to prevent the workpiece 12 from being placed in the wrong position.

[0060] The working process of Example 2:

[0061] Place the ball pin 13 on the positioning seat 1, so that the ball head 1301 of the ball pin 13 is placed in the ball head receiving groove 101, and the ball seat 1302 is placed in the placement area 102, and then insert the workpiece 12 into the positioning pin 10 on the support frame 9 so that the central axis of the bottom positioning hole is colinear with the central axis of the riveted ball pin 13.

[0062] The first detector 2 measures the distance between the bottom of the ball end of the ball stud 13 and the first detector 2. If the length meets the set threshold, it means that the length of the ball stud 13 is correct. Otherwise, an alarm buzzer sounds and the length of the ball stud 13 is abnormal.

[0063] If there is no alarm, proceed to the next step. Press the start button to activate the cylinder, so that the first end of the detection rod 3 passes through the placement area 2 and abuts against the ball seat of the ball pin 13. The distance between the first end of the detection rod 3 and the rotating shaft 4 is L1, and the distance between the second end of the detection rod 3 and the rotating shaft 4 is L2. Since L1 is less than L2, the diameter deviation of the ball seat 1302 is amplified by the lever principle and then fed back to the second detector 5. If the diameter is greater than or less than the set value, the green light of the second detector 5 is not on and the specification of the ball pin 13 is wrong. On the contrary, the green light of the second detector 5 is on and the specification of the ball pin 13 is correct. After the end face diameter and length of the ball pin 13 meet the requirements, the equipment starts riveting to rivet the workpiece 12 and the ball pin together. After the riveting is completed, the workpiece 12 is taken out upwards and waits for the next workpiece 12 to be riveted.

[0064] A riveting ball pin identification device is installed on the original positioning seat 1. Under the premise of not affecting the production efficiency, it can identify the ball head of abnormal model, ensure the stability of the riveting quality, and eliminate the occurrence of defective products from the source.
