DETAILED DESCRIPTION

[0026] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is described in detail below in conjunction with the accompanying drawings. The description in this part is only exemplary and explanatory and should not have any limiting effect on the scope of protection of the present invention.

[0027] like Figure 1-2 and Figure 10-11As shown, the specific structure of the present invention is: a metal parts welding equipment capable of detection, including a frame 1, the frame 1 is provided with a welding carrier 2 matched with a main body 11, the frame 1 is also provided with a welding device 3 matched with the welding carrier 2, a column loading mechanism 4 and a transfer device 5, the transfer device 5 is also matched with a main body conveying device 6 and a blanking conveying device 7, the blanking conveying device 7 includes a blanking conveying trough 91 arranged on the frame 1, the blanking conveying trough 91 is matched with a detection device 92, the detection device 92 includes a detection mounting block 95 arranged on the outer wall of the blanking conveying trough 91, the detection mounting block 95 is provided with a detection lifting cylinder 96 and a detection limit column 99, the detection lifting cylinder 96 is connected to the detection block 9 7. The detection block 97 is located above the unloading conveying trough 91 and is provided with a detection interception block 98 that cooperates with the product in the unloading conveying trough 91 on one side of the conveying end. The detection block 97 is located above the unloading conveying trough 91 and is embedded with a contact sensor. The upper end of the detection limit column 99 is a detection pressure sensor 100. A defective product ejection port 93 corresponding to the intercepted product is provided on one side wall of the unloading conveying trough 91. The defective product ejection port 93 is matched with a defective product collection box 94. A defective product ejection cylinder 101 is provided on the other side wall of the unloading conveying trough 91 opposite to the defective product ejection port 93. The defective product ejection cylinder 101 is connected with a defective product ejection block 102 that can be inserted into the unloading conveying trough 91.

[0028] The specific operation is as follows: first, the main body is conveyed by the main body conveying device 6, and then the main body 11 on the main body conveying device 6 is clamped and transferred by the transfer device 5, so that the main body 11 is placed on the welding carrier 2, and then the column 14 is placed into the column hole 12 of the main body 11 by the column loading mechanism 4, and then it is welded by the welding device 4, and then the welded product is taken away by the transfer device 5 and placed on the unloading conveying trough 91, and conveyed through the conveying structure in the unloading conveying trough 91 until it is intercepted by the detection interception block 98, and then the detection lifting cylinder 96 drives the detection block 97 to continue to descend until it cannot descend, and the welding is judged by observing the signal conditions of the contact sensor under the detection block 97 and the detection pressure sensor 100. Whether the connected product is qualified or not, if it can generate induction signals in any way, it proves that the welded metal parts are qualified. If only the pressure sensor 100 generates induction signals, it proves that the height of the column 14 is not enough, and it is an unqualified product. If only the contact sensor generates induction signals, it proves that the height of the column 14 is too high, and it is also an unqualified product. For unqualified products, the unqualified product ejection cylinder 101 drives the unqualified product ejection block 102 to move, and then the unqualified products are pushed out from the unqualified product ejection port 93 into the unqualified product collection box 94. For qualified products, the detection lifting cylinder 96 rises, and then the detection interception block 98 is separated from the product, and the product continues to be conveyed in the unloading conveying trough 91. In this way, the detection is also integrated, and the defective products can be screened.

[0029] like Figure 4-5 As shown, the welding carrier 2 includes a loading seat 31 arranged on the frame 1, the loading seat 31 is a hollow seat body, and the upper part of the loading seat 31 is installed with a loading bearing sleeve 32 by bolts, and a loading shaft 33 is installed in the loading bearing sleeve 32. The lower part of the loading shaft 33 cooperates with the loading rotation motor 38 through a pulley 36 and a transmission belt 37. The loading rotation motor 38 is installed on a loading motor mounting seat 39 arranged under the frame 1, and the upper part of the loading shaft 33 is provided with a loader that cooperates with the main body 11.

[0030] The specific operation of the loading device 2 is as follows: the main body 11 is placed in the loading device.

[0036] The specific operation of the welding device 3 is as follows: after completing the discharge of the main body 11 and the plug 14, the welding movable seat 23 is driven to move by the welding movable cylinder 22, so that the welding head of the welder 25 is matched with the parts of the main body 11 and the plug 14 that need to be welded, and then welding is performed by the argon arc welder. During the welding process, in order to increase the width of the weld, after completing a circle of welding, the welder 25 can be driven to move slightly by the spiral propeller 24 (the threaded rod is advanced by threaded engagement, and the advancement amplitude is small), and then another circle of welding is performed, so as to ensure the reliability of the welding.

[0037] like Figure 6 As shown, the transfer device 5 includes a transfer mounting seat 51 arranged on the frame 1, and a transfer turntable 52 equipped with a driving structure is arranged on the transfer mounting seat 51, and four transfer arms 53 are evenly arranged on the outer side of the transfer turntable 52, and each transfer arm 53 is connected to a transfer clamper, and the transfer clamper includes a transfer clamping seat 55 arranged on the transfer arm 53, and a transfer clamping cylinder 56 is arranged on the transfer clamping seat 55, and the transfer clamping cylinder 56 is connected to two transfer clamping movable blocks 57, and the two transfer clamping movable blocks 57 are connected to transfer clamping blocks 59, and the two transfer clamping blocks 59 can realize the clamping of the main body 11.

[0040] like Figure 7As shown, the main conveying device 6 includes a main conveying trough 60 arranged on the frame 1, and a main intercepting block 65 is arranged at the end of the main conveying trough 60, and a first conveying belt 61, a second conveying belt 63 and a third conveying belt 64 with increasing conveying speeds are arranged in sequence along the conveying direction in the main conveying trough 60, and the third conveying belt 64 is composed of two sections of conveying belts with the main conveying trough 60, and a transfer contact sensing screen 54 is embedded between the two sections of the conveying belts.

[0041] The specific operation of the main body conveying device 6 is as follows: the main body 11 is placed on the first conveyor belt 61, and then after being conveyed by the first conveyor belt 61, it will enter the second conveyor belt 63, and then continue to be conveyed to the third conveyor belt 64, and then it will be intercepted by the main body interception block 65. After being intercepted, it is clamped by the transfer clamp. After clamping, the transfer contact sensing screen 54 can be used to detect whether the position and diameter of the matching hole 13 are accurate, and then it is transferred by the transfer device. The end of the main body conveying trough 60 is located on one side of the rotation direction of the transfer device, and a main body discharge port will be opened, so that it can be ensured that the main body 11 can be transferred out from the main body discharge port, and there is no need to realize the lifting of the main body 11, saving equipment costs.

[0043] The specific operation of the plug-in column feeding mechanism is as follows: first, the plug-in columns 14 are placed on the plug-in column conveyor belt 74 at intervals. After the first plug-in column 14 is conveyed, it will be intercepted by the plug-in column interception block, and then the conveying of the plug-in column conveyor belt 74 is stopped. Then, the plug-in column picking and placing lifting cylinder 78 drives the plug-in curve picking and placing shock absorber 79 and the plug-in column picking and placing device 80 to descend, so that the plug-in column picking and placing device 80 absorbs the plug-in column, and then the plug-in column picking and placing lifting cylinder 78 is raised again, thereby separating the plug-in column 14 from the plug-in column conveying groove 73, and then the plug-in column picking and placing lifting cylinder 78 is used to pick up the plug-in column 14. The movable cylinder 75 drives the column picking and placing movable frame 76 to move, so that the column 14 is above the main body 11 of the pneumatic telescopic rod top sleeve being loaded, and then the column picking and placing lifting cylinder 78 drives the column picking and placing shock absorber 79 and the column picker 80 to descend, so that the column 14 is inserted into the column hole 12 of the main body 11, and continues to descend, so that the main body 11 is completely inserted into the clamping sleeve 35 and the loading sleeve 34.

[0045] The column picking and placing shock absorber 79 is shock-absorbing through the shock-absorbing spring 82, and the cooperation of the shock-absorbing sleeve 84 and the shock-absorbing plug rod 85 ensures that there will be no positional deviation during the shock absorption process, and the column absorber is connected with the hemispherical part of the column 71 through the suction matching sleeve 86, so that the suction matching sleeve 86 and the platform part of the column 71 are sealed and matched, and then the column 14 can be sucked by the suction air pump 87. In the process of placing, the suction matching sleeve 86 can also press down the platform on the upper part of the main body 11 after completing the discharge of the column 14, which can play a downward operation on the main body, and the design of the shock-absorbing spring can avoid damage to the product due to excessive downward pressure.
