[0039] As Figure 2As shown in the figure, a hinge detection and riveting device of the present application is used for riveting the tail end of the ball head pin. It includes a machine table 1, an indexing plate 2 arranged on the machine table 1, a height difference detection mechanism 3, a riveting mechanism 4 and a blanking mechanism 5. Among them, four loading fixtures are arranged at equal intervals along the circumference on the indexing plate 2; four working stations are formed on the machine table 1 and around the indexing plate 2. Among them, the first working station 1-1 is an artificial loading station, the height difference detection mechanism 3 is installed at the second working station 1-2, the riveting mechanism 4 is arranged at the third working station 1-3, and the blanking mechanism 5 is arranged at the fourth working station 1-4. A material collection area 1-5 is arranged on one side of the fourth working station 1-4. The material collection area 1-5 includes a good product collection area and a defective product collection area, and the processed and detected hinges are classified and collected.

[0040] As Figure 2 shown in the figure, manually load materials at the first working station 1-1, place the hinge to be riveted on the loading fixture 21 of the indexing plate 2, and then the indexing plate 2 rotates. The first hinge is driven to the second working station 1-1 to detect the height difference of the ball head pin; at the same time, the loading operation of the second hinge is carried out at the first working station 1-1; then the indexing plate 2 rotates again, and the first hinge is brought to the third working station 1-3 for riveting operation; when the riveting is completed, the indexing plate 2 rotates again, drives the first hinge to the fourth working station 1-4 for blanking operation, and places the finished product in the material collection area 1-5 according to the detection result. At the same time, the second hinge reaches the third working station 1-3, the third hinge reaches the second working station 1-2, and the fourth hinge is loaded at the first working station 1-1. In this way, it runs in a cycle. Only one worker needs to manually operate the loading, and multiple hinges can be processed simultaneously, so it can save labor and effectively improve efficiency.

[0041] As Figure 2-3 shown in the figure, preferably, a locking component 22 is arranged between the machine table 1 and the indexing plate 2 to lock the position of the indexing plate 2 and prevent it from rotating during the processing, causing processing errors. The locking component 22 includes a locking cylinder 221 placed on the machine table 1. The output end of the locking cylinder 221 faces upward and is connected with a locking plug 222. A locking hole 223 is cooperatively opened on the indexing plate 2. When the locking cylinder 221 acts, it drives the locking plug 222 to rise, and the locking plug 222 is correspondingly inserted into the locking hole 223 to complete the locking of the indexing plate 2, so that the position of the indexing plate 2 remains stable during the processing.

[0042] As Figure 1-5As shown in the figure, the material loading fixture 21 is arranged on the machine table 1 and is used to support the hinge. A through hole is vertically formed through the material loading fixture 21, and a placement sleeve 212 is fixed in the through hole. A mutually connected accommodating cavity 213 and a through hole 214 are arranged in the placement sleeve 212. The accommodating cavity 213 is located above the through hole 214 and is used to accommodate the pin head end 631 of the ball pin; a transmission rod 215 is movably arranged in the through hole 214, and a limiting block 216 is arranged at the upper end of the transmission rod 215. The limiting block 216 is clamped above the through hole 214 and is located in the accommodating cavity 213. The transmission rod 215 can move up and down along the through hole 214, and the limiting block 216 at its upper end can correspondingly abut against the pin head end 631 located in the accommodating cavity 213. When the material loading fixture 21 is fixed on the indexing plate 2, a detection hole is formed in the indexing plate 2 corresponding to the placement sleeve 212, which is convenient for subsequent detection of the pin head end 631 of the ball pin in the accommodating cavity 213.

[0043] As Figure 2-5 shown in the figure, a protruding positioning pin 211 is arranged on the upper end surface of the material loading fixture 21. The positioning pin 211 is correspondingly arranged on one side of the placement sleeve 212 and is used to cooperate with the positioning hole 64 on the hinge 6. When the ball pin is assembled on the hinge and is located in the placement sleeve 212, the positioning hole 64 on the hinge can be correspondingly sleeved on the positioning pin 211 to fix the placement position of the hinge, which is convenient for subsequent processing. Preferably, a detection camera is arranged above the first station 1-1 to take pictures and detect the hinge on the material loading fixture 21 to determine whether the model of the hinge manually loaded meets the standard.

A first detection component and a second detection component are arranged on the first support frame 31 and are used to detect the height of the ball pin. Among them, the first detection component is arranged above the indexing plate 2 and is used to detect the height difference of the pin tail end 632 of the ball pin, and the second detection component is arranged below the indexing plate 2 and is used to detect the height difference of the pin head end 631 of the ball pin.

[0045] As Figure 2-6As shown in the figure, the first detection component includes a first lifting cylinder 32 disposed at the upper end of the first support frame 31. The output end of the first lifting cylinder 32 faces downward and is connected to a first height measuring instrument 33. Among them, the first height measuring instrument 33 can adopt a first displacement sensor. The first displacement sensor includes a telescopic first probe 331 and a contact sleeve 332 sleeved on the circumference of the first probe 331. The first lifting cylinder 32 drives the first height measuring instrument 33 to descend. The first probe 331 first contacts the upper end surface of the tail end 632 of the pin, and then the first height measuring instrument 33 continues to descend until the contact sleeve 332 contacts the upper end surface of the first structural part 61. By measuring the height difference between the contact sleeve 332 from the moment the first probe 331 contacts the upper end surface of the tail end 632 of the pin to the moment the contact sleeve 332 contacts the upper end surface of the first structural part 61, the height of the tail end 632 of the pin protruding from the upper end surface of the first structural part 61 can be obtained, and it can be determined whether it meets the model standard according to the measured value.

[0046] As Figure 2-6 shown in the figure, the second detection component includes a second lifting cylinder 34 disposed at the lower end of the first support frame 31. The output end of the second lifting cylinder 34 faces upward and is connected to a second height measuring instrument 35. Among them, the second height measuring instrument 35 can adopt a second displacement sensor. The second displacement sensor includes a second probe 351. The second lifting cylinder 34 drives the second probe 351 to rise. The second probe 351 first contacts the lower end of the transmission rod 215, and then the second probe 351 continues to rise, pushing the transmission rod 215 to continue rising until the limiting block 216 at the upper end of the transmission rod 215 abuts against the lower end surface of the head end 631 of the pin. In this way, the distance between the head end 631 of the ball pin and the transmission rod 215 is measured. According to the internal height of the accommodating cavity 213, the height of the head end 631 of the pin placed in the accommodating cavity 213 can be obtained, and it can be determined whether it meets the model standard according to the measured value.

[0047] As Figure 2-8 shown in the figure, the riveting mechanism 4 includes a riveting machine 41 placed on the machine table 1. The output end of the riveting machine 41 is further provided with a floating pressing member 42. The pressing member 42 includes a pressing head 421. The pressing head 421 and the riveting machine 41 are connected to each other through a telescopic guide rod 422. An elastic member 423 is sleeved on the circumference of the guide rod 422. The output end of the riveting machine 41 moves downward. The pressing head 421 first presses on the upper end surface of the first structural part 61 to press the hinge tightly on the loading fixture 21. The riveting machine 41 continues to move downward, and the riveting head contacts the tail end of the pin for riveting. Preferably, an avoidance hole is provided at the position of the pressing head 421 corresponding to the riveting head, so that the pressing head 421 is correspondingly placed on the circumference of the riveting head and can be pressed on the circumference of the hinge riveting position to improve the stability of the hinge during the riveting process.

[0048] As Figure 2-8As shown in the figure, the blanking mechanism 5 includes a second support frame 51 placed on the machine table 1. A material taking mechanism and a transverse movement driving assembly 52 for driving the material taking mechanism to move are arranged on the second support frame 51.

The output end of the third lifting cylinder 54 faces downward and is configured with a connecting support plate 55. Preferably, a vertically extending guiding slide rail is correspondingly arranged on the connecting plate 53, and the connecting support plate 55 is slidably arranged on the guiding slide rail through a slider. The third lifting cylinder 54 drives the connecting support plate 55 to slide up and down along the guiding slide rail to improve the stability of the connecting support plate 55 during the sliding process. In this embodiment, the transverse movement driving assembly can adopt structures such as a motor screw module, and no specific limitation is made here.

[0049] As Figure 2 and 9 shown, a detecting member and a material taking member are configured on the connecting support plate 55. The detecting member is used to detect whether the height of the pin tail end after riveting meets the requirements, and the material taking member takes and places the finished products into the good product collection area and the defective product collection area respectively according to the detection result.

[0050] As Figure 2 and 9 shown, the detecting member includes a third height measuring instrument 56 configured on the connecting support plate 55. In this embodiment, the third height measuring instrument 56 has the same structure as the first height measuring instrument 33, and will not be elaborated here.

The output end of the material taking cylinder 57 faces downward and is connected with a magnetic suction head 58 for sucking the hinge. A stripping sleeve 59 is fixed on the connecting support plate 55. The magnetic suction head 58 is placed in the stripping sleeve 59 and can move up and down along the central hole of the stripping sleeve 59. The material taking cylinder 57 drives the magnetic suction head 58 to move downward to the lower part of the stripping sleeve 59. The magnetic suction head 58 sucks the hinge. The transverse movement driving assembly 52 drives the magnetic suction head 58 and the hinge to move above the material collection area 1-5. The material taking cylinder 57 drives the magnetic suction head 58 to move upward until the hinge contacts the stripping sleeve 59, and the magnetic suction head 58 no longer contacts the hinge, and the hinge drops to the lower material collection area 1-5.

[0052] As Figure 9 shown, preferably, a vision sensor 510 is also configured on the connecting plate 53 to take a photo test of the diameter of the hinge pin tail end on the fourth station 1-4 loading and fixing jig 21 to determine whether it meets the standard.
