The connecting holes 43 are vertical, and the cross-sectional size of the connecting holes 43 is adapted to the cross-sectional size of the rotating plate 44. A fixed frame 47 is fixedly connected to the surface of the collection frame 41 corresponding to the connecting holes 43, and a rotating block 46 is rotatably connected to the inner wall of the fixed frame 47. The cross-section of the rotating block 46 is "L"-shaped, and an inlay hole 49 is provided on the surface of the rotating block 46. The inner wall of the inlay hole 49 slides through the arc surface of the fixed column 45, and both ends of the inner wall of the fixed frame 47 are sleeved with coil springs 48, and the two ends of the coil spring 48 are respectively fixedly connected to the fixed frame 47 and the rotating block 46, and the side walls of the two ends of the collection frame 41 are fixedly connected with a pull rod 42, and the cross-section of the pull rod 42 is "U"-shaped.

[0033] In the embodiments of the present invention, please refer to Figure 4 and Figure 5 The auxiliary device 5 includes four rotating columns 52 and a magnetic frame 51. The bottom ends of the four rotating columns 52 are rotatably connected to the upper surface of the machine tool 1. The cross-section of the four rotating columns 52 is semicircular. The side walls of the magnetic frame 51 at both ends are provided with slots 53 corresponding to the positions of the rotating columns 52.

[0034] The working principle of a spring end face grinder for precision spring processing provided by the utility model is as follows: in the process of precision processing of springs by using the grinder, in order to facilitate the collection and transportation of the processed springs, one side of the collection frame 41 is first plugged into the fixed column 45 through two connecting holes 43, and then the rotating plate 44 on the surface of the fixed column 45 is rotated to allow the rotating plate 44 to penetrate the collection frame 41 and rotate the rotating plate 44 at the same time, so that the rotating plate 44 is placed horizontally.

In this process, in order to prevent the fixed column 45 from falling off from the collection frame 41, the "L"-shaped rotating block 46 in the fixed frame 47 is used at the same time, so that the inlay hole 49 opened on the surface of the rotating block 46 slides through the rotating plate 44 and the fixed column 45.

At this time, in order to facilitate the collection of the metal debris, the magnetic frame 51 is first plugged and fixed to the surface of the machine tool 1, and then the positioning shafts 54 at both ends of the machine tool 1 are rotated to allow the positioning shafts 54 to drive the rotation and movement of the position of the rotating column 52, so that the rotating column 52 with a semicircular cross-section is plugged and limited with the slots 53 opened at both ends of the magnetic frame 51. At this time, the position of the entire magnetic frame 51 will not be able to shift, and then the limiting rod 57 is plugged and fixed to the limiting slot 56 through the limiting block 58 to avoid the position deflection of the rotating column 52. At this time, the entire magnetic frame 51 will absorb and collect the metal debris in the processing process.
