Technical Field

[0001] This application relates to the technical field of motor assembly, and in particular to an installation device for a motor magnetic shield. Background Technology

[0002] A magnetic shield is a tool used to shield electronic signals. Its function is to shield the influence of external electromagnetic waves on internal circuits and to prevent internally generated electromagnetic waves from radiating outwards. It is an essential component of motors.

[0003] Reference Figures 1-3 In the warehouse, a manual press 10 is typically used to install magnetic shielding covers on small motors. For motors of different sizes, a correspondingly sized lower press block 20 needs to be replaced. The lower press block 20 has a connecting plate 23 and a connecting seat 22. The connecting seat 22 is used to place the motor requiring the magnetic shielding cover, and its size is the same as the motor size. The connecting plate 23 also has a connecting hole 2301 for installing a connector 21. The connector 21 is used to fix the connecting plate 23 to the machine base. The lower end of the connector 21 is slidably connected to a connecting groove 12 on the machine base, and the upper end of the connector 21 has a thread that connects to a connecting nut 2101. Tightening the connecting nut 2101 onto the connecting rod 2102 secures the connecting plate 23 to the machine base.

[0004] When it is necessary to replace the lower pressure block 20, first remove the connecting nut 2101, then remove the connecting plate 23, and replace it with a lower pressure block 20 of a different size. Then, reposition the new lower pressure block 20 on the machine base through the connecting piece 21 and the connecting nut 2101 to complete the replacement of the lower pressure block.

[0005] The replacement process for the pressure block 20 is rather cumbersome and affects work efficiency. Utility Model Content

[0014] Preferably, the lower stamping mounting hole is provided with a positioning post, and the lower stamping block is provided with a positioning hole connected to the positioning post.

[0015] By adopting the above technical solution, the lower stamping block is positioned in the lower stamping mounting hole by the positioning pin, thereby ensuring that the center position of the lower stamping block is always on one end of the lower stamping mounting hole.

[0016] Preferably, the quick-release mechanism further includes a fixing component. The benchtop manual press is provided with a base, and the fixing component is used to install the quick-release mounting block on the base.

The outer contour of the mounting block 4303 is the same as that of the mounting groove 3101. The mounting block 4303 is slidably connected in the mounting groove 3101. The mounting rod 4302 is vertically fixedly connected to the upper end of the mounting block 4303. The fixing nut 4301 is threadedly connected to the upper end of the mounting rod 4302. The two mounting ears 4101 are respectively fitted onto the two mounting rods 4302 through their own mounting holes 4102. After the two mounting ears 4101 are fitted onto the two mounting rods 4302, the fixing nut 4301 is tightened onto the mounting rod 4302, thereby fixing the quick-release mounting block 41 onto the stamping seat 31.

[0046] Reference Figures 8-10 The quick-release mechanism 40 also includes quick-release components 42, which are used to clamp the quick-release mounting block 41. In this embodiment, there are 6 sets of quick-release components 42, which are respectively arranged on the 6 sides of the quick-release mounting block 41. Each quick-release component 42 includes a quick-release mounting bracket 4201, a quick-release rod 4203, and an elastic element 4204. One end of the quick-release mounting bracket 4201 is fixedly connected to the side of the quick-release mounting block 41, and the other end of the quick-release mounting bracket 4201 is provided with a connecting sliding hole 4202. The quick-release mounting block 41 is provided with a connecting sliding hole 4202. 02. A quick-release sliding hole 4103 is provided on the coaxial line. One end of the quick-release rod 4203 is slidably connected to the quick-release sliding hole 4103, and the other end of the quick-release rod 4203 is slidably connected to the connecting sliding hole 4202. A lower punching mounting hole 4105 is provided at the upper end of the quick-release mounting block 41. The lower punching mounting hole 4105 is a blind hole and is used to place the lower punching block 60. The quick-release sliding hole 4103 communicates with the lower punching mounting hole 4105. The end of the quick-release rod 4203 passes through the quick-release sliding hole 4103 and into the lower punching mounting hole 4105.

[0047] Reference Figure 8A stop piece 4205 is fixedly connected to the quick-release lever 4203, and an elastic element 4204 is also sleeved on the quick-release lever 4203. The stop piece 4205 is located inside the quick-release mounting bracket 4201. One end of the elastic element 4204 abuts against the stop piece 4205, and the other end of the elastic element 4204 abuts against the quick-release mounting bracket 4201. The elastic element 4204 is used to reset the quick-release lever 4203. In this embodiment, the elastic element 4204 is a spring.

[0048] Reference Figures 8-10 The lower stamping block 60 includes a connecting block 63. An abutment block 62 is fixedly connected to the upper end of the connecting block 63. A placement ring 61 is fixedly connected to the upper end of the abutment block 62. The connecting block 63 has six quick-release grooves 64 arranged circumferentially along the axis of the connecting block 63. Each quick-release rod 4203 corresponds to one quick-release groove 64, and the width of each quick-release groove 64 is equal to the diameter of each quick-release rod 4203. A insert 42 is fixedly connected to the end of each quick-release rod 4203. 06. Each quick-release slide 64 is provided with a groove 65 that connects to the insert 4206 of the quick-release rod 4203. In this embodiment, the insert 4206 is spherical and the groove 65 is a ball groove, which facilitates the disassembly and assembly of the lower punch block 60. In this embodiment, the quick-release slide 64 is vertically arranged and its lower end is inclined towards the axis of the connecting block 63. The purpose of this design is that when the lower punch block 60 is pushed down, the lower punch block 60 will generate a force that pushes outward along the disassembly rod, so as to open the quick-release rod 4203. A positioning post 4104 is vertically fixedly connected in the lower punch mounting hole 4105. The lower punch block 60 is provided with a positioning hole 67, and the lower punch block 60 is mounted on the positioning post 4104 through the positioning hole 67.

[0049] Reference Figures 8-10 The installation process of the lower stamping block 60 is as follows: First, align the positioning hole 67 of the lower stamping block 60 with the positioning post 4104 on the quick-release mounting block 41, and align the six quick-release grooves 64 of the lower stamping block 60 with the six quick-release rods 4203 respectively. Then, push the lower stamping block 60 down. While the lower stamping block 60 moves down, it pushes the six quick-release rods 4203 to move outward. When the lower end of the abutment block 62 on the lower stamping block 60 abuts against the upper end of the quick-release mounting block 41, the insert 4206 of the quick-release rod 4203 is just inserted into the groove 65 of the connecting block 63. At this time, the lower stamping block 60 is restricted by the quick-release rod 4203 and will not rotate or move on its own in the lower stamping mounting hole 4105.

[0050] Reference Figure 7 , Figure 9 , Figure 10As shown, the lower end of the motor 50 is provided with a motor shaft 53, and a blind hole is also opened on the positioning post 4104. The blind hole on the positioning post 4104 is used to place the motor shaft 53. The lower end of the motor 50 is also provided with a positioning pit 54. A positioning head 66 is fixedly connected to the placement ring 61 of the lower punch block 60. The motor 50 is positioned on the lower punch block 60 through the positioning pit 54.

[0051] The implementation principle of the motor magnetic shielding cover installation device in this application embodiment is as follows: the motor 50 that needs to be equipped with the magnetic shielding cover 52 is placed on the lower stamping block 60, and then the magnetic shielding cover 52 is placed on the upper stamping block. The two electrode slots of the magnetic shielding cover 52 are aligned with the positioning slots 3604 on the upper stamping block 60. Then, the lower pressing rod 34 is rotated to move the lower stamping block downwards to press the magnetic shielding cover 52 onto the motor 50 with an interference fit. Then, the motor 50 with the magnetic shielding cover 52 is removed from the lower stamping block. Another motor 50 with the magnetic shielding cover 52 is placed on the lower stamping block 60. When the lower stamping block 60 needs to be replaced, the original lower stamping block 60 is pulled out and another lower stamping block 60 is inserted into the quick-release mounting block 41.
