[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-4 The utility model provides a technical solution: a deep hole honing head that is convenient for reducing weight, comprising a main body 1, a honing bar 2, a threaded head 3, an automatic telescopic rod 4, a moving block 5, a first fixed plate 6, a push rod 7, a second fixed plate 8, a slider 9, a slide groove 10, a disc 11 and a power output end 12;

[0021] When honing, if Figure 1 and Figure 2 As shown, the automatic telescopic rod 4 is started. Since the output end of the automatic telescopic rod 4 is fixedly installed with a moving block 5, the automatic telescopic rod 4 drives the moving block 5 to move up and down. Then, the outer end of the moving block 5 is equiangularly fixed with a first fixed plate 6. Two push plates 7 are rotatably installed on each first fixed plate 6 through a latch. The push plates 7 are respectively rotatably connected with second fixed plates 8 through latches, so that the up and down movement of the moving block 5 drives the up and down movement of the first fixed plate 6. Then, the up and down movement of the first fixed plate 6 causes the push rod to rotate, thereby pushing and pulling the second fixed plate 8. Since the seven second fixed plates 8 are all fixedly installed with honing bars 2, the honing bars 2 are pushed out of the outer end of the slot opened on the main body 1, so that the honing bars 2 protrude from the main body 1. Then, the power device drives the power output end 12 to rotate and move up and down, so that the part of the honing head 2 protruding from the main body 1 repeatedly grinds the workpiece.

[0022] like Figure 2 and Figure 4As shown, since a disc 11 is fixedly installed at the bottom end of the main body 1, 7 slide grooves 10 corresponding to the slider 9 are opened on the disc 11, and the slider 9 is fixedly installed at the bottom of the second fixed plate 8, when the second fixed plate 8 is pushed and pulled, the slider 9 slides in the slide groove 10, thereby stabilizing the operation of the honing bar 2 and reducing the damage of the honing bar 2 during the honing process. Then a threaded head 3 is connected to the main body 1, so the honing head is threadedly connected to the power output end 12, so that the honing head is easy to disassemble, thereby facilitating the replacement and cleaning of the honing head. Since the threaded head 3 is limited and connected to the top of the main body 1 of the honing head by an L-shaped plate and screws, the automatic telescopic rod 4 is fixedly connected to the threaded rod 3 by a rod, so it is convenient to check the internal situation of the honing head and repair the automatic telescopic rod 4.
