[0065] The dummy shaft blanking machine includes a second machine platform, a flip loading assembly 2, a casing handling assembly, a casing conveying assembly, a dummy shaft conveying assembly 8, a nut conveying assembly 9, a nut tightening assembly 10 and a pressing assembly 6;

[0066] The flip loading assembly 2, the housing handling assembly, the housing conveying assembly, the dummy shaft conveying assembly 8, the nut conveying assembly 9, the nut tightening assembly 10 and the pressing assembly 6 have the same structure as the dummy shaft loader;

[0067] The dummy shaft blanking machine obtains the finished products that have passed the test in the noise testing machine and blanks the dummy shafts and nuts from them.

[0068] The noise testing machine is a combination of multiple process machines, and the assembled finished product is transported through the multiple process machines through a mechanical handling component.

[0069] The mechanical handling assembly includes a test manipulator, a test track and a test cylinder;

[0070] The test track is arranged on one side of the plurality of process machines, the test robot is arranged on the test track, the output end of the test cylinder is connected to the test robot, and the test robot is driven by the test cylinder to move on the test track.

[0071] Specifically, in the previous process of the dummy shaft loading machine, the motor has been assembled. In order to test various performances of the motor, it is necessary to insert a shaft into the motor to fully test the motor. Therefore, the dummy shaft is inserted into the motor, and then after the test, the dummy shaft is removed, and then the qualified motor is unloaded. In this article, the motor is collectively referred to as the "housing" in the following text;

[0072] First, the dummy shaft loader places the casing from the previous process on the loading base 202. The loading base 202 is then driven by the loading cylinder along the loading guide rail 201 to move to the first machine platform 1. The casing is then rotated to the corresponding position by the rotation motor 203 and then transported to the casing carrier 4 by the casing handling component, wherein the casing handling component is the robot 3.

[0073] After the housing is placed on the housing carrier 4, the initial position of the housing carrier 4 on the conveying guide rail 5 is at the far right end. Then, the housing carrier 4 will gradually move to the left on the conveying guide rail 5 driven by the conveying cylinder. During the gradual leftward movement, the dummy shaft conveying assembly 8 and the nut conveying assembly 9 will assemble the housing with the prepared dummy shaft and nut, so that the assembled housing can be easily tested for good quality.

[0074] Among them, the dummy shaft clamping member 807 will be driven by the dummy shaft longitudinal cylinder 804 to rise and fall on the dummy shaft longitudinal guide rail 805 as the dummy shaft connecting seat 806 is driven by the dummy shaft longitudinal cylinder 804, and the dummy shaft longitudinal guide rail 805 will be driven by the dummy shaft transverse cylinder to move laterally on the dummy shaft transverse guide rail 802 as the dummy shaft connecting plate 803 is driven by the dummy shaft transverse cylinder. Therefore, the dummy shaft clamping member 807 will clamp the dummy shaft from the outside and then move it in the transverse and longitudinal directions, moving the dummy shaft from the outside to the casing carrier 4, inserting the dummy shaft into the center of the casing, and the dummy shaft will be inserted from the top of the opening of the casing to the bottom;

[0075] At the same time as the dummy shaft is inserted, the nut is also caught from the outside by the nut longitudinal guide rail 905 and the nut transverse guide rail 902 through the nut clamping part 907. It is not placed on the casing, but on the nut tightening assembly 10, that is, the adjusting part 1007. When the casing carrier 4 transports the casing with the dummy shaft inserted to the leftmost end of the transport guide rail 5, the top pressure seat 603 will be driven by the clamping cylinder to sink on the clamping guide rail 602, and the top pressure seat 603 will be in contact with the dummy shaft, giving the dummy shaft a downward pressure. Moreover, the casing in this position is subjected to the downward pressure of the top pressure seat 603 above, and the adjusting part at the bottom is pressed down. 1007 will apply an upward force to the part of the bottom of the casing where the dummy shaft passes through. Specifically, the abutting cylinder 1004 drives the tightening slide 1003 to generate an upward force on the abutting guide rail 1002, that is, it drives the rotary adjustment member 1007 to abut the dummy shaft at the bottom of the casing. It does not need to resist the downward pressure of the pressure seat 603, and only needs to keep it level. When the rotary adjustment member 1007 abuts the dummy shaft, the rotating motor 1005 will drive the coupling 1006 and the rotary adjustment member 1007 to rotate, driving the nut on the rotary adjustment member 1007 to be sleeved on the dummy shaft at the bottom of the casing and rotate along with the thread, and the nut is fixed to the bottom of the casing along with the dummy shaft;

[0076] After the nut is assembled on the bottom of the housing and the housing and the dummy shaft are fixed, the upper and lower forces applied by the pressing seat 603 and the adjusting member 1007 are withdrawn and separated. At this time, the housing carrier 4 moves the housing with the assembled dummy shaft and nut from the leftmost end to the rightmost end of the conveying guide rail 5 along with the conveying cylinder, and then the manipulator 3 grabs and conveys it to the noise tester for testing;

[0077] After the test is completed, the qualified products will be carried by the test robot into the dummy shaft blanking machine, where the dummy shaft and nut will be unloaded and blanked, and then the casing will be transported to the outside world;

[0078] In the same way, in the dummy shaft blanking machine, the initial position of the casing carrier 4 on the dummy shaft blanking machine on the transport guide rail 5 is at the rightmost end, and then the casing carrier 4 will gradually move to the left on the transport guide rail 5 driven by the transport cylinder. In the process of gradually moving to the left, it will be transported to the leftmost end, and the dummy shaft on the top of the casing will be pressed tightly by the pressing seat 603. The rotary adjustment member 1007 at the bottom will apply an upward force to the part of the bottom of the casing where the dummy shaft passes through, and then the nut at the bottom of the casing will be loosened by the rotation of the rotary adjustment member 1007. Finally, the nut will stop on the rotary adjustment member 1007, and then, in the process of the casing carrier 4 moving from the leftmost end to the rightmost end of the transport guide rail 5, it will be taken out of the casing by the dummy shaft clamping member 807, and the nut stopped on the rotary adjustment member 1007 will be taken out by the nut clamping member 907 for recycling to the next casing test to form a complete loop.

[0079] In this embodiment, the dummy shaft nut reflux assembly 7 is further included, and the dummy shaft nut reflux assembly 7 is laterally connected to the dummy shaft loading machine and the dummy shaft unloading machine respectively;

[0080] The pseudo-shaft nut return assembly 7 includes a lower belt 702, an upper belt 701, a belt motor 704, a lifting module 703, a material receiving seat 707, a linear module 705 and a material pushing seat 706, as well as a number of material transfer seats 708 and a fixed vertical plate 709;

[0081] The upper belt 701 and the lower belt 702 are connected in parallel up and down through several fixed vertical plates 709. The output ends of the belt motor 704 are respectively connected to the upper belt 701 and the lower belt 702. Several material transfer carriers 708 are used to carry material nuts and false shafts. The lifting module 703 is arranged at the ends of the upper belt 701 and the lower belt 702. The material receiving seat 707 and the linear module 705 are both arranged on the lifting module 703. The pushing seat 706 is arranged on the linear module 705.

[0082] Specifically, the upper and lower belts 702 pass through the entire dummy shaft loading machine, pass through multiple noise test machines, and then pass through the dummy shaft unloading machine, thereby reciprocating the nuts and dummy shafts used for casing testing.

[0083] The upper belt 701 is used for processing at the top surface of the first and second machines, and the lower belt 702 is used for conveying at the inner position of the first and second machines. The upper belt 701 and the lower belt 702 are combined to form a counterclockwise rotation cycle.

[0084] The upper belt 701 and the lower belt 702 are fixed by a plurality of fixed vertical plates 709 on both sides. At the ends of the upper belt 701 and the lower belt 702, there is a nut and a dummy shaft that are transferred from the lower belt 702 to the upper belt 701. The specific process is as follows:

[0085] There are two positions in the plurality of material transfer carriers 708, which are used to place nuts and dummy shafts respectively. After placing the nuts and dummy shafts, the material transfer carrier 708 will be driven by the belt motor 704 of the upper belt 701 and the lower belt 702. Assuming that at the rightmost end, that is, the position of the dummy shaft unloader, when the lower belt 702 moves toward the upper belt 701, first, the lifting module 703 will drive the receiving seat 707 and the linear module 705 to descend to align with the end of the lower belt 702. Because the linear module 705 and the pusher seat 706 have a horizontal moving mechanism, the pusher seat 70 6 There is a forward and backward moving mechanism relative to the linear module 705. Therefore, the material pushing seat 706 on the linear module 705 will extend to assist in pushing the material transfer carrier 708 from the lower belt 702 to the material receiving seat 707, and play a role in limiting the material receiving seat 707. Then, the material receiving seat 707 will rise with the lifting module 703 to a position aligned with the upper belt 701. Similarly, the material pushing seat 706 will push the material transfer carrier 708 in the material receiving seat 707 into the upper belt 701, and then it will be transported from the upper belt 701 of the dummy shaft unloader to the dummy shaft loader.
