Embodiment Construction
[0043] Such as Figure 1 to Figure 3 , these three figures show the main structure of a device for positioning and pressing pins in this embodiment:
[0044] In the present embodiment, the movable rotating shaft that is used for pressing pin is the rotating shaft of an electric motor; The purpose of this device is to pass coaxial member 13 and movable rotating shaft 11 with pin 19 along the radial direction of movable rotating shaft 11 simultaneously, The movable shaft 11 is provided with a first pin hole 14, and the coaxial member 13 is a worm-shaped part.
[0045] A fixed frame 20 is fixed on the elongated slide rail 9, and the fixed frame 20 can limit the position of the main body 12; there is a sliding frame 30, on which the second pin inserted into the movable shaft can be fixed The coaxial part 13 of the hole 15; the sliding frame 30 is slidably fitted on the slide rail 9, and the sliding frame 30 fixes the coaxial part 13 in position and attitude, and aligns the second...

The invention discloses a method for positioning a pressure pin and a device for implementing the method. The method is characterized by comprising the following steps of: positioning: threading a guide pin sliding coaxially to a first pin hole in a movable rotating shaft to fix the movable rotating shaft; preparing a piece: arranging a coaxial piece at one end of the movable rotating shaft, wherein a second pin hole in the coaxial piece is parallel to the first pin hole; aligning a pin with the first pin hole; and pressing the pin: sheathing the coaxial piece on the movable rotating shaft, pulling the guide pin out from the first pin hole, continuously sheathing the coaxial piece on the movable rotating shaft till the first pin hole and the second pin hole are arrived and the guide pin is completely retreated from the first pin hole, and completely pressing the pin into the first pin hole and the second pin hole. According to the corresponding device, the movable rotating shaft is fixed by using a fixed rack, and the coaxial piece is fixed by using a sliding rack; and the device is also provided with a pressure pin mechanism, and the pin is arranged on a pressure pin head of the pressure pin mechanism. The movable rotating shaft, the coaxial piece and the pin are accurately positioned in a sliding guide pin mode, so that the operation of the pressure pin is reliable and stable.
Description
technical field [0001] The invention relates to a method for assembling a pin and a corresponding device, in particular to a method for positioning a pressing pin and a device for realizing the method. Background technique [0002] The coaxial fittings on which the rotating shaft is fixed by pins are a common fixing method. Firstly, the fixed coaxial fittings are sleeved on the rotating shaft, the pin holes are aligned, and then the pins are pressed into the pin holes to achieve the purpose. For example, a common standard motor has a radial pin hole on its power output shaft. Coaxial accessories such as worms, gears, etc. need to be pierced and fitted on the power output shaft, and the pins pass through the worm or gear at the same time. , and the PTO shaft, complete the fixation. [0003] For mechanisms with movable shafts like motors and gearboxes, the movable shafts have been set on the corresponding main body, the axial direction is basically fixed, and the circumferent...
