Description
Technical Field
[0001] The utility model relates to the technical field of permanent magnet synchronous motors for new energy vehicles, and in particular to a fast pin installation device. Background Art
[0002] The core technology of new energy vehicles is the design and manufacture of drive motor controllers and the production and manufacturing of drive assemblies. At present, major domestic suppliers have basically achieved fully automatic or semi-automatic assembly, but there are still a few processes that require manual operation (such as spline grease application, signal harness docking, electrical performance testing, etc.), resulting in a low level of quality control and failure to meet customer quality requirements.
[0003] At present, during the production of the reducer used in the permanent magnet synchronous motor of new energy vehicles, the pins on the reducer are manually installed by employees. This operation requires that the pins be installed in place and cannot be tilted. The existing process method is difficult for employees to operate and has low efficiency. The pins cannot be effectively installed in place and cannot be guaranteed to be installed without tilt. It is easy to cause the pin holes on the casing to not effectively cooperate with the pins on the reducer when the whole machine is assembled. During assembly, it is easy to cause defects such as abnormal noise in the product. Therefore, the current assembly process urgently needs a new pin installation process to solve practical problems. To this end, a quick pin installation device is proposed. Utility Model Content

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0019] Reference Figure 1-4 As shown, a quick pin installation device includes a mounting seat 1 and two positioning members 2, the two positioning members 2 are respectively connected to the two sides of the mounting seat 1, and a positioning pin 3 is connected to the bottom surface of one end of each positioning member 2 away from the mounting seat 1. A cylindrical pressing groove 11 is opened on the top of the mounting seat 1, and a pressing head 4 is provided on the pressing groove 11 for installing pins.
[0020] In this embodiment, a cylindrical pin groove 13 is provided at the bottom of the mounting seat 1, and a cylindrical connecting groove 12 is provided at the bottom of the pressing groove 11 and is connected to the pin groove 13. The pressing groove 11, the connecting groove 12 and the pin groove 13 are coaxially arranged, and the diameter of the pin groove 13 is slightly larger than the diameter of the pin, so that the pin can be easily inserted into the pin groove 13.
[0021] In this embodiment, a connecting column 41 is connected to the bottom of the pressure head 4 , a pressing rod 42 is connected to the bottom of the connecting column 41 , the connecting column 41 is slidably connected to the pressing groove 11 , and the pressing rod 42 is slidably connected to the connecting groove 12 .
[0022] In this embodiment, a limiting groove 14 is opened on the outer wall of the mounting seat 1 and is connected to the pressing groove 11. A limiting hole 43 is set on the connecting column 41. A limiting screw 5 is installed on the limiting hole 43. The limiting screw 5 is slidably connected to the limiting groove 14. The limiting screw 5 is used to prevent the pressure head 4 from detaching from the mounting seat 1 to avoid.
[0023] In this embodiment, the mounting seat 1 and the pressure head 4 are both made of nickel-chromium alloy material, which has high strength and corrosion resistance and wear resistance.
[0024] Working process and principle:
[0025] When in use, first place the pin into the pin slot 13, move the entire device to the reducer product, place the two positioning pins in the positioning holes of the product, and complete the positioning with the product. At this time, the pin slot 13 is aligned with the pin hole on the product, press the pressure head 4 to press the pressure head down, and press the pin in the pin slot 13 into the pin hole of the product through the pressure rod 42. Since the pin in the pin slot 13 is always kept in a vertical state, the pressed pin will not tilt and is pressed into place, which reduces the difficulty and intensity of employee operations and improves the product qualification rate.
